Inflammation-induced processes commence with the activation of signalling pathways at the cellular level, which mobilize inflammatory cells and stimulate the secretion of chemokines, cytokines, and damage-associated molecular pattern molecules (DAMPs). Physical effort stimulates inflammation, contributing to muscle repair and regeneration. We have examined the impact of different protocols of progressive-effort tests on T-cell DAMP levels, extracellular cleavage products (fibronectin and hyaluronan), and Th-cell-related cytokine levels among soccer players. Thirty male soccer players with a median age of 17 (16–22) years performed different defined protocols for progressive exercise until exhaustion: (1) YO-YO intermittent recovery test level 1 (YYRL1, n = 10); (2) maximal multistage 20 m shuttle run (Beep, n = 10); and mechanical treadmill (MT, n = 10); and (3) shuttle-run test (n = 10). Blood samples were taken three times as follows: at baseline, post effort, and in recovery. Significantly higher post-effort concentrations of IL-4, IL-6, IL-10, and IFN-γ were observed in the Beep group, IL-4 in the YYRL1 group, and IL-6 and IFN-γ in the MT group as compared with the baseline values. Recovery values were significantly higher for concentrations of IL-4, IL-10, and IFN-γ in the YYRL1 group, only for IFN-γ in the Beep group, and for IL-6, IL-10, and INF-γ in the MT group as compared with the baseline values. Post-effort concentrations of DEFβ2, Hsp27, Fn, and UA in the Beep group and Hsp27 and HA in the YYRL1 group were significantly higher as compared with the baseline values. It seems the performed efficiency test protocols caused a short-term imbalance in Th1/Th2 cytokine levels without giving common molecular patterns. The rapidity of these changes was apparently related to specific physical movements and the type of running surface.

This study uncovers the predictive relationship of middle school students’ ability beliefs (self-efficacy and expectancy-related beliefs) and incentives (outcome expectancy, importance, interest, and usefulness) to intention, cardiovascular fitness, and teacher-rated effort in physical education. Participants (N = 252; 118 boys, 134 girls) completed questionnaires assessing their ability beliefs, incentives, and intention for future participation in physical education, and then had their cardiovascular fitness assessed with the Progressive Aerobic Cardiovascular Endurance Run (PACER) test. Students’ effort in class was rated by their respective physical education teachers. Correlation analysis yielded significantly positive relationships between ability beliefs and incentives. Regression results revealed that ability beliefs, importance, interest, and usefulness significantly predicted intention for future participation. Ability beliefs also emerged as significant predictors of PACER test scores whereas self-efficacy was the only predictor of teacher-rated effort. Implications for educational practice are discussed.

Summary Background During karate fight muscles work at a very high intensity, and their contractions are extremely strong. The movement pattern contains a great number of feints, dodges, frequent changes in movements’ tempo and direction, hits and kicks, all of which is highly stressful for athlete’s organism, including the immune system. Methods T lymphocyte subsets’ distribution and selected cytokines in peripheral blood of three elite karate athletes aged 30 years old (range 21–31 years) with minimum 15 years of training experience were analysed in two experiments: at the beginning of the preparatory phase (a progressive test until exhaustion; an analysis of immune system’s selected parameters and cardiorespiratory fitness measures, including VO2max, VE, AT, MVV, MET, Rf), and during the start-up period (Karate Championships; an analysis of selected parameters of the immune system). Results Maximal effort caused an increase in total lymphocyte percentage (p<0.05). A decrease in Th cells in recovery (p<0.05 compared to post-exercise), and an increase in Th naïve cells in recovery (p<0.05) were observed. A significant increase in CD8+ central memory cells (p<0.05) was found only after the progressive test, and no changes in both central and effector memory subsets of CD4+ cells during the first experiment. An increase (p<0.05) in Treg and Th1 and a decrease (p<0.05) in Th2 cells’ distribution during recovery time were found. Additionally, changes (p<0.05) in TNF-α, IL-6, IL-8, IL-10 and IL-12p70 were observed. Conclusion Post-effort disorder in immune balance activated compensation pathways involving CD4+ cells. Treg and Th1 cells seem to be subsets of key importance involved in the anabolic effect of physical effort, at least among karate athletes.

The use of fitness testing is a practical means for measuring components of health-related fitness, but there is currently substantial debate over the motivating effects of these tests. Therefore, the purpose of this study was to examine the cross-fertilization of achievement and friendship goal profiles for early adolescents involved in the Progressive Aerobic Cardiovascular Endurance Run (PACER). Participants were 214 middle school students who reported their achievement goals, social goals, and preparation effort toward a PACER test. Performance was also examined. Confirmatory factor analysis supported the six-factor approach–avoidance model. Cluster analysis highlighted three distinct profiles. The high-goals profile group reported significantly higher amounts of effort put forth in preparation for the PACER test. Our findings suggest that the cross-fertilization of approach and avoidance achievement and social goals can provide important information about effort and performance on fitness testing in middle school physical education.

With the belief that theoretical integration in motivation may help us better understand motivational behavior, we designed this study to explore adolescents’ motivational profiles and their associations with knowledge acquisition, leisure-time exercise behaviors, and cardiorespiratory fitness. Middle school students from a large urban inner-city school district (N = 603, ages 12–14) completed questionnaires assessing motivational constructs and leisure-time exercise behavior. Knowledge and cardiorespiratory fitness were also assessed with a knowledge test and the Progressive Aerobic Cardiovascular Endurance Run (PACER) test, respectively. Using hierarchical cluster analysis, we found that students’ motivation in physical education could be explained from a multi-theoretical perspective. The interactive patterns among different motivation constructs were homogeneous overall and associated with in-class effort, knowledge, and leisure-time exercise behavior. These findings suggest that students’ development in physical education may depend upon a collective impact of changes in knowledge, physical activity ability, and sources of motivation.

ABSTRACT Objective To evaluate the acute effects of maternal and fetal hemodynamic responses in pregnant women submitted to fetal Doppler and an aerobic physical exercise test according to the degree of effort during the activity and the impact on the well-being. Methods Transversal study with low risk pregnant women, obtained by convenience sample with gestational age between 26 to 34 weeks. The participants carry out a progressive exercise test. Results After the exercise session, reduced resistance (p=0.02) and pulsatility indices (p=0.01) were identified in the umbilical artery; however, other Doppler parameters analyzed, in addition to cardiotocography and fetal biophysical profile did not achieve significant change. Maternal parameters obtained linear growth with activity, but it was not possible to establish a standard with the Borg scale, and oxygen saturation remained stable. Conclusion A short submaximal exercise had little effect on placental blood flow after exercise in pregnancies without complications, corroborating that healthy fetus maintains homeostasis even in situations that alter maternal hemodynamics.

A avaliação da variabilidade da frequência cardíaca (VFC) possibilita quantificar a participação do sistema nervoso autônomo simpático e parassimpático. Clinicamente, esta relaciona-se com o prognóstico e risco de morte súbita em diversas afecções no homem, mas ainda permanece incerta em importantes enfermidades caninas como a degeneração mixomatosa valvar e obesidade. Dentre as alternativas terapêuticas capazes de modificar o balanço autonômico de forma benéfica, o exercício físico se destaca para o homem, entretanto, ainda pouco pesquisado em cães. Neste estudo, avaliou-se o comportamento da VFC, no domínio do tempo, em cães com endocardiose e obesidade mórbida, assim como os efeitos do treinamento sobre as funções autonômicas e hemodinâmicas de cães saudáveis. Nos cães do presente estudo, a endocardiose valvar e obesidade mórbida não modificaram os índices de VFC, sendo estes semelhantes aos índices observados nos cães hígidos. Em etapa posterior, o teste de esforço progressivo e treinamento físico preconizados foram bem tolerados pelos cães saudáveis. Maior participação autonômica parassimpática foi detectada por índices de VFC (SDANN, rMSSD e SDNN), frequências cardíacas mínima, máxima e sua amplitude, além da mudança percentual dos ritmos apresentados no teste de esforço após o treinamento. Em seu aspecto hemodinâmico observou-se melhor função diastólica (relação E/A mitral), redução dos índices indicadores de pré-carga (IEPFd e diâmetro AE) e pós-carga (IEPFs).
Heart rate variability (HRV) is a tool capable to measure the sympathetic and parasympathetic autonomic nervous system participation. These measurements are clinically related to prognosis and sudden death risk in different human diseases, but it remains unknown in dogs even in important disorder such as myxomatous valvar degeneration and obesity. Physical exercises has a special role on therapy of patients with heart disorders, leading to an autonomic balance improvement, but these effects are not still studied in dogs. This study evaluated time domain HRV in dogs with endocardiosis and obesity, and in parallel, the effects of physical training on hemodynamic and autonomic function in health dogs. Myxomatous mitral valve degenetation, and obese dogs presented similar HRV measures compared to health dogs. In subsequent study, the progressive physical effort test and training program were well tolerated for health dogs. Increased parasympathetic participation was detected by HRV (SDANN, rMSSD and SDNN), minimum, maximum and amplitude heart frequencies, besides the rhythm percentage modifications in the effort test after training. In the hemodynamic evaluation improvement of diastolic function (E/A mitral), decreased preload (IEPFd and diâmetro AE) and afterload (IEPFs) indexes were observed. Concluding, the dogs from this study with an initial phase of endocardiosis (class Ib) or morbid obesity did not present autonomic damages detectable by HRV, and training cold change the autonomic control and hemodynamic function in health dogs, opening a new research perspective to use it in canine cardiac diseases.

Les données issues de la recherche en neurosciences permettent de considérer la dépression comme une affection invalidante générale, caractérisée par des déficits neurocognitifs et comportementaux, au delà des symptômes dépressifs cliniques définis dans les classifications nosographiques. Ces déficits coexistent à la phase aiguë d’un épisode dépressif caractérisé (EDC) et interfèrent dans la prise de décision et réalisation d’un comportement orienté vers un but, et la sensation d’effort associée. Ils semblent persister en période de rémission clinique, altérant la qualité de la réponse thérapeutique et fonctionnelle et aggravant à terme le pronostic du trouble. L’objectif de ce travail est d’identifier des marqueurs neurocognitifs objectivement mesurables en pratique clinique, et d’étudier leur association au pronostic d’un EDC, afin de mieux prédire les probabilités de rémission et d’optimiser les stratégies de prescription thérapeutique des patients. L’altération des processus neurocognitifs liés à la récompense constitue un premier marqueur de vulnérabilité du trouble dépressif : dans une étude explorant la production d’un effort moteur dans le but d’obtenir une récompense, les patients déprimés présentaient un déficit de production d’effort, à la différence des sujets sains. Ce trouble de la motivation par incitation - processus sous tendu en imagerie fonctionnelle chez le sujet sain par l’activation de circuits cortico-striataux ventraux -pourrait constituer une dimension spécifique de la maladie dépressive. Participant à l’altération des processus de prise de décision et d’action, ce déficit motivationnel est associé, et possiblement secondaire, à des déficits plus spécifiquement cognitifs que nous avons ensuite étudiés. Dans une étude explorant plusieurs fonctions cognitives chez des patients déprimés au sein d’une large cohorte, la présence d’un ralentissement psychomoteur séquellaire après 6 à 8 semaines de traitement – chez des patients pourtant en rémission clinique -, était positivement et de manière indépendante, significativement corrélée au nombre d’épisodes dépressifs passés, constituant ainsi un marqueur d’une sévérité « cumulative » du trouble dépressif. Enfin, dans une revue de la littérature sur le caractère progressivement évolutif des déficits cognitifs dans le trouble dépressif unipolaire, nous avons discuté l’existence d’un effet « neurotoxique » cérébral de l’accumulation d’EDC, à l’origine de troubles neurocognitifs et de conséquences sur le cours évolutif de la maladie (risque majoré de rémission clinique et/ou fonctionnelle partielle, de récurrence, d’évolution démentielle). Un des principaux intérêts de l’identification de marqueurs de vulnérabilité cliniques et cognitifs est de mettre en évidence leur rôle prédictif du cours évolutif d’un épisode -ou d’un trouble- dépressif. Dans une étude menée sur une cohorte de plus de 500 patients déprimés, une variable attentionnelle (d2 test d’attention) était capable de prédire l’évolution ultérieure vers la rémission complète (clinique et fonctionnelle) de façon significative, linéaire, et indépendante des autres variables et de représenter un marqueur-trait de la dépression, aisément utilisable en pratique clinique. D’autres marqueurs cognitifs (tels que les fonctions exécutives) ont montré une valeur prédictive élevée de la réponse thérapeutique, avec une précision proche de celle de marqueurs d’imagerie ou électrophysiologie, selon les résultats d’une méta-analyse récente, justifiant leur emploi dans le suivi des patients
Hese deficits coexist in the acute phase of a depressive episode and interfere with decision-making and goal-directed behaviors, and the associated feeling of effort. They appear to persist in periods of clinical remission, decreasing the quality of the therapeutic and functional response and lately worsening the prognosis of the disorder. The aim of this work is to identify objectively measurable neurocognitive markers in clinical practice, and to study their association with the prognosis of a depressive episode, in order to better predict remission and potentially to optimize therapeutic prescribing strategies for patients accordingly. The impairment of neurocognitive processes related to reward constitutes a first vulnerability marker for major depressive disorder (MDD): in a study assessing the production of motor effort in order to obtain a reward, depressed patients had a deficit in production of effort, unlike healthy subjects. Such deficit in incentive motivation - a process underpinned by the activation of ventral cortico-striatal circuits in healthy subjects - may constitute a specific dimension of MDD. It participates in the decision-making and action processes impairments and is associated with – and possibly a consequence of- more specifically cognitive deficits. In a study assessing several cognitive functions in a large cohort of depressed patients, the persistence of psychomotor retardation after 6 to 8 weeks of treatment - in patients considered as being in clinical remission - was positively and independently correlated with the number of past depressive episodes, thus constituting a marker of "cumulative" marker of past depressive episodes. Finally, in a literature review on the progressive evolution of cognitive deficits in MDD, we discussed the existence of a “neurotoxic” effect of the lifetime accumulation of depressive episodes on neurocognitive deficits and its consequences on disease prognosis (increased risk of incomplete functional/clinical remission, relapses, evolution towards dementia). One of the main interest in identifying clinical and cognitive markers of vulnerability is to highlight their capacity to predict the course of a depressive episode-or disorder. In a study based on a cohort of more than 500 depressed patients, a measurement of attention (d2 attention test) was able to significantly and independently predict the subsequent course towards complete remission (clinical and functional) and to constitute a trait -marker of depression, easy to use in clinical practice. Other cognitive markers (such as executive functions) have shown high predictive values for therapeutic response, comparable to those provided by imaging or electrophysiology markers, according to the results of a recent meta-analysis, that emphasizes the interest of using them in patient’s follow-up. Finally, in order to better assess the prognosis of depressive disorder, we have shown that Seasonal Affective Disorder (SAD) diagnosis criteria - which nevertheless represents a specific depressive disorder with well-known physiopathology substrates (construction validity) - had a low predictive validity, prompting to consider this disorder as a temporary expression of a mood disorder, rather than a specific disorder. The identification of clinical tools measuring motivational and cognitive deficits in clinical routine and predicting the course of a depressive episode or disorder represents a major challenge in the improvement of personalized therapeutic management and the long-term prognosis in depressed patients

Psychological factors specific to overuse injury pain in physical activity contexts were explored within a social identity theoretical framework. Study 1 involved development of a method for designating overuse injury pain occurrence of hikers (N = 751), along with exploration of relationships between psychological measures, overuse injury pain occurrence, and effort levels. The findings of this cross-sectional, mixed-methods investigation revealed that social identification, social identity content, and mental toughness differentiated hikers who incurred overuse injury pain or selected a higher-effort behaviour from those who did not. From qualitative analysis, several social identity constructs (i.e., group member's presence, in-group status, social creativity, additional social identity content) emerged as contributors to overuse injury occurrence. The focus of Study 2 was a prospective examination of the aforementioned psychological factors in relation to overuse injury severity of hikers (N = 283). Additionally, the Test of Intentions to Reduce Effort (TIRE) was developed to identify individuals with susceptibility to higher overuse injury severity. Results provided evidence of factorial, construct, and predictive validity of TIRE factor scores. TIRE factors and social identity content significantly predicted higher severity of hikers' overuse injury pain. Mental toughness scores moderated the relationship between social identification and overuse injury severity. Study 3 consisted of a qualitative examination of social identity mechanisms of overuse injury pain in a physical activity context, CrossFit®, involving the presence of group leaders, and in which group members view each other. Findings revealed mechanisms pertaining to social identity content, in-group status, and social threats. Overall, the findings support a new means for assessing overuse injury occurrence and susceptibility to higher overuse injury severity, whilst demonstrating the potential applicability of social identity theory to the study of overuse injury. Knowledge gained may ultimately aid development of interventions to reduce overuse injury occurrence and severity of physical activity participants.

The relation between metabolic demand and maximal oxygen consumption during exercise have been investigated in different areas of knowledge. In the health field, the determination of maximal oxygen consumption (VO2max) is considered a method to classify the level of physical fitness or the risk of cardiocirculatory diseases. The accuracy to obtain data provides a better evaluation of functional responses and allows a reduction in the error margin at the moment of risk classification, as well as, at the moment of determination of aerobic exercise work load. In Brasil, the use of respirometry associated to ergometric test became an opition in the cardiorespiratory evaluation. This equipment allows predictions concerning the oxyredutase process, making it possible to identify physiological responses to physical effort as the respiratory threshold. This thesis focused in the development of mathematical models developed by multiple regression validated by the stepwise method, aiming to predict the VO2max based on respiratory responses to physical effort. The sample was composed of a ramdom sample of 181 healthy individuals, men and women, that were randomized to two groups: regression group and cross validation group (GV). The voluntiars were submitted to a incremental treadmill test; objetiving to determinate of the second respiratory threshold (LVII) and the Peak VO2max. Using the m?todo forward addition method 11 models of VO2max prediction in trendmill were developded. No significative differences were found between the VO2max meansured and the predicted by models when they were compared using ANOVA One-Way and the Post Hoc test of Turkey. We concluded that the developed mathematical models allow a prediction of the VO2max of healthy young individuals based on the LVII
A rela??o entre a demanda metab?lica e o consumo de oxig?nio durante a pr?tica de exerc?cios f?sicos ? alvo de investiga??o em distintas ?reas do conhecimento. No campo da sa?de, a determina??o do consumo m?ximo de oxig?nio (VO2m?x) ? considerada um m?todo para classificar o n?vel de aptid?o f?sica ou risco de doen?as cardiocirculat?rias. A obten??o de dados de forma acurada possibilita uma melhor avalia??o das respostas funcionais, o que permite reduzir a margem de erros tanto no momento da classifica??o dos riscos, como tamb?m no momento da determina??o das cargas de treinamento aer?bico. No Brasil a utiliza??o da ventilometria conjugado ao teste de ergom?trico passou a ser uma op??o na avalia??o cardiorrespirat?ria. O emprego deste equipamento possibilita inferir sobre o processo de oxidorredutase, permitindo identificar respostas fisiol?gicas ao esfor?o como o limiar ventilat?rio. A presente tese centrou-se no desenvolvimento de modelos matem?ticos desenvolvidos por meio de regress?o m?ltipla com valida??o pelo m?todo stepwise com o objetivo de predi??o do VO2m?x tomando como base, as respostas ventilat?rias ao esfor?o. Para tanto, o estudo contou com uma amostra aleat?ria de 181 indiv?duos saud?veis, de ambos os sexos, que foram randomizados em dois grupos: grupo de regress?o e o grupo de valida??o cruzada (GV). Os volunt?rios foram submetidos a teste cardiopulmonar em esteira rolante em protocolo incremental; onde se visou a determina??o do limiar ventilat?rio II (LVII) e o VO2m?x de pico. Atrav?s da aplica??o do m?todo adi??o forward foram desenvolvidos 11 modelos de predi??o do VO2m?x em esteira rolante. N?o foram encontradas diferen?as significativa entre o VO2m?x mensurado com os preditos pelos modelos quando comparados pelo teste t pareado. Os resultados possibilitam-nos concluir que os modelos matem?ticos desenvolvidos permitem estimar o VO2m?x de indiv?duos jovens e h?gidos, tendo como ponto de refer?ncia o LVII

Because no laboratory test or imaging study is both highly sensitive and highly specific for multiple sclerosis, some uncertainty often accompanies the diagnosis. Various guidelines have been developed to assist the clinician, including the much-modified and commonly used McDonald criteria. Typical features of the history, the physical examination, and magnetic resonance imaging findings usually allow for a secure diagnosis. However, limitations inherent in any testing modality still pose challenges. This is especially true for diagnosis of primary progressive multiple sclerosis because the sensitivity and specificity of the evaluations are lower.

Cystic fibrosis (CF) is an inherited, autosomal recessive, multisystem disease. Dysfunction of the cystic fibrosis transmembrane conductance regulator protein (CFTR) in epithelial cells is the primary defect in CF. Defects in CFTR are the cause for lung disease, exocrine pancreatic insufficiency and failure, male infertility, and liver disease. CF can present with a variety of respiratory and gastrointestinal signs, including meconium ileus in the newborn period, hypernatremic dehydration, pulmonary insufficiency, nasal polyps, and insulin-dependent diabetes mellitus. As affected children grow, dysfunction in CFTR leads to chronic and progressive lung disease, characterized by suppurative infection and the development of bronchiectasis. CFTR dysfunction also affects exocrine function, leading to pancreatic insufficiency, malabsorption, and growth failure. In the past, history and physical exam with sweat chloride testing were the cornerstones of diagnosis. Diagnosis is now made with the newborn screening test for immunoreactive trypsinogen.

Nationalism: Past as Prologue began as a single volume being compiled by Ad Akande, a scholar from South Africa, who proposed it to me as co-author about two years ago. The original idea was to examine how the damaging roots of nationalism have been corroding political systems around the world, and creating dangerous obstacles for necessary international cooperation. Since I (Bruce E. Johansen) has written profusely about climate change (global warming, a.k.a. infrared forcing), I suggested a concerted effort in that direction. This is a worldwide existential threat that affects every living thing on Earth. It often compounds upon itself, so delays in reducing emissions of fossil fuels are shortening the amount of time remaining to eliminate the use of fossil fuels to preserve a livable planet. Nationalism often impedes solutions to this problem (among many others), as nations place their singular needs above the common good. Our initial proposal got around, and abstracts on many subjects arrived. Within a few weeks, we had enough good material for a 100,000-word book. The book then fattened to two moderate volumes and then to four two very hefty tomes. We tried several different titles as good submissions swelled. We also discovered that our best contributors were experts in their fields, which ranged the world. We settled on three stand-alone books:” 1/ nationalism and racial justice. Our first volume grew as the growth of Black Lives Matter following the brutal killing of George Floyd ignited protests over police brutality and other issues during 2020, following the police assassination of Floyd in Minneapolis. It is estimated that more people took part in protests of police brutality during the summer of 2020 than any other series of marches in United States history. This includes upheavals during the 1960s over racial issues and against the war in Southeast Asia (notably Vietnam). We choose a volume on racism because it is one of nationalism’s main motive forces. This volume provides a worldwide array of work on nationalism’s growth in various countries, usually by authors residing in them, or in the United States with ethnic ties to the nation being examined, often recent immigrants to the United States from them. Our roster of contributors comprises a small United Nations of insightful, well-written research and commentary from Indonesia, New Zealand, Australia, China, India, South Africa, France, Portugal, Estonia, Hungary, Russia, Poland, Kazakhstan, Georgia, and the United States. Volume 2 (this one) describes and analyzes nationalism, by country, around the world, except for the United States; and 3/material directly related to President Donald Trump, and the United States. The first volume is under consideration at the Texas A & M University Press. The other two are under contract to Nova Science Publishers (which includes social sciences). These three volumes may be used individually or as a set. Environmental material is taken up in appropriate places in each of the three books. * * * * * What became the United States of America has been strongly nationalist since the English of present-day Massachusetts and Jamestown first hit North America’s eastern shores. The country propelled itself across North America with the self-serving ideology of “manifest destiny” for four centuries before Donald Trump came along. Anyone who believes that a Trumpian affection for deportation of “illegals” is a new thing ought to take a look at immigration and deportation statistics in Adam Goodman’s The Deportation Machine: America’s Long History of Deporting Immigrants (Princeton University Press, 2020). Between 1920 and 2018, the United States deported 56.3 million people, compared with 51.7 million who were granted legal immigration status during the same dates. Nearly nine of ten deportees were Mexican (Nolan, 2020, 83). This kind of nationalism, has become an assassin of democracy as well as an impediment to solving global problems. Paul Krugman wrote in the New York Times (2019:A-25): that “In their 2018 book, How Democracies Die, the political scientists Steven Levitsky and Daniel Ziblatt documented how this process has played out in many countries, from Vladimir Putin’s Russia, to Recep Erdogan’s Turkey, to Viktor Orban’s Hungary. Add to these India’s Narendra Modi, China’s Xi Jinping, and the United States’ Donald Trump, among others. Bit by bit, the guardrails of democracy have been torn down, as institutions meant to serve the public became tools of ruling parties and self-serving ideologies, weaponized to punish and intimidate opposition parties’ opponents. On paper, these countries are still democracies; in practice, they have become one-party regimes….And it’s happening here [the United States] as we speak. If you are not worried about the future of American democracy, you aren’t paying attention” (Krugmam, 2019, A-25). We are reminded continuously that the late Carl Sagan, one of our most insightful scientific public intellectuals, had an interesting theory about highly developed civilizations. Given the number of stars and planets that must exist in the vast reaches of the universe, he said, there must be other highly developed and organized forms of life. Distance may keep us from making physical contact, but Sagan said that another reason we may never be on speaking terms with another intelligent race is (judging from our own example) could be their penchant for destroying themselves in relatively short order after reaching technological complexity. This book’s chapters, introduction, and conclusion examine the worldwide rise of partisan nationalism and the damage it has wrought on the worldwide pursuit of solutions for issues requiring worldwide scope, such scientific co-operation public health and others, mixing analysis of both. We use both historical description and analysis. This analysis concludes with a description of why we must avoid the isolating nature of nationalism that isolates people and encourages separation if we are to deal with issues of world-wide concern, and to maintain a sustainable, survivable Earth, placing the dominant political movement of our time against the Earth’s existential crises. Our contributors, all experts in their fields, each have assumed responsibility for a country, or two if they are related. This work entwines themes of worldwide concern with the political growth of nationalism because leaders with such a worldview are disinclined to co-operate internationally at a time when nations must find ways to solve common problems, such as the climate crisis. Inability to cooperate at this stage may doom everyone, eventually, to an overheated, stormy future plagued by droughts and deluges portending shortages of food and other essential commodities, meanwhile destroying large coastal urban areas because of rising sea levels. Future historians may look back at our time and wonder why as well as how our world succumbed to isolating nationalism at a time when time was so short for cooperative intervention which is crucial for survival of a sustainable earth. Pride in language and culture is salubrious to individuals’ sense of history and identity. Excess nationalism that prevents international co-operation on harmful worldwide maladies is quite another. As Pope Francis has pointed out: For all of our connectivity due to expansion of social media, ability to communicate can breed contempt as well as mutual trust. “For all our hyper-connectivity,” said Francis, “We witnessed a fragmentation that made it more difficult to resolve problems that affect us all” (Horowitz, 2020, A-12). The pope’s encyclical, titled “Brothers All,” also said: “The forces of myopic, extremist, resentful, and aggressive nationalism are on the rise.” The pope’s document also advocates support for migrants, as well as resistance to nationalist and tribal populism. Francis broadened his critique to the role of market capitalism, as well as nationalism has failed the peoples of the world when they need co-operation and solidarity in the face of the world-wide corona virus pandemic. Humankind needs to unite into “a new sense of the human family [Fratelli Tutti, “Brothers All”], that rejects war at all costs” (Pope, 2020, 6-A). Our journey takes us first to Russia, with the able eye and honed expertise of Richard D. Anderson, Jr. who teaches as UCLA and publishes on the subject of his chapter: “Putin, Russian identity, and Russia’s conduct at home and abroad.” Readers should find Dr. Anderson’s analysis fascinating because Vladimir Putin, the singular leader of Russian foreign and domestic policy these days (and perhaps for the rest of his life, given how malleable Russia’s Constitution has become) may be a short man physically, but has high ambitions. One of these involves restoring the old Russian (and Soviet) empire, which would involve re-subjugating a number of nations that broke off as the old order dissolved about 30 years ago. President (shall we say czar?) Putin also has international ambitions, notably by destabilizing the United States, where election meddling has become a specialty. The sight of Putin and U.S. president Donald Trump, two very rich men (Putin $70-$200 billion; Trump $2.5 billion), nuzzling in friendship would probably set Thomas Jefferson and Vladimir Lenin spinning in their graves. The road of history can take some unanticipated twists and turns. Consider Poland, from which we have an expert native analysis in chapter 2, Bartosz Hlebowicz, who is a Polish anthropologist and journalist. His piece is titled “Lawless and Unjust: How to Quickly Make Your Own Country a Puppet State Run by a Group of Hoodlums – the Hopeless Case of Poland (2015–2020).” When I visited Poland to teach and lecture twice between 2006 and 2008, most people seemed to be walking on air induced by freedom to conduct their own affairs to an unusual degree for a state usually squeezed between nationalists in Germany and Russia. What did the Poles then do in a couple of decades? Read Hlebowicz’ chapter and decide. It certainly isn’t soft-bellied liberalism. In Chapter 3, with Bruce E. Johansen, we visit China’s western provinces, the lands of Tibet as well as the Uighurs and other Muslims in the Xinjiang region, who would most assuredly resent being characterized as being possessed by the Chinese of the Han to the east. As a student of Native American history, I had never before thought of the Tibetans and Uighurs as Native peoples struggling against the Independence-minded peoples of a land that is called an adjunct of China on most of our maps. The random act of sitting next to a young woman on an Air India flight out of Hyderabad, bound for New Delhi taught me that the Tibetans had something to share with the Lakota, the Iroquois, and hundreds of other Native American states and nations in North America. Active resistance to Chinese rule lasted into the mid-nineteenth century, and continues today in a subversive manner, even in song, as I learned in 2018 when I acted as a foreign adjudicator on a Ph.D. dissertation by a Tibetan student at the University of Madras (in what is now in a city called Chennai), in southwestern India on resistance in song during Tibet’s recent history. Tibet is one of very few places on Earth where a young dissident can get shot to death for singing a song that troubles China’s Quest for Lebensraum. The situation in Xinjiang region, where close to a million Muslims have been interned in “reeducation” camps surrounded with brick walls and barbed wire. They sing, too. Come with us and hear the music. Back to Europe now, in Chapter 4, to Portugal and Spain, we find a break in the general pattern of nationalism. Portugal has been more progressive governmentally than most. Spain varies from a liberal majority to military coups, a pattern which has been exported to Latin America. A situation such as this can make use of the term “populism” problematic, because general usage in our time usually ties the word into a right-wing connotative straightjacket. “Populism” can be used to describe progressive (left-wing) insurgencies as well. José Pinto, who is native to Portugal and also researches and writes in Spanish as well as English, in “Populism in Portugal and Spain: a Real Neighbourhood?” provides insight into these historical paradoxes. Hungary shares some historical inclinations with Poland (above). Both emerged from Soviet dominance in an air of developing freedom and multicultural diversity after the Berlin Wall fell and the Soviet Union collapsed. Then, gradually at first, right wing-forces began to tighten up, stripping structures supporting popular freedom, from the courts, mass media, and other institutions. In Chapter 5, Bernard Tamas, in “From Youth Movement to Right-Liberal Wing Authoritarianism: The Rise of Fidesz and the Decline of Hungarian Democracy” puts the renewed growth of political and social repression into a context of worldwide nationalism. Tamas, an associate professor of political science at Valdosta State University, has been a postdoctoral fellow at Harvard University and a Fulbright scholar at the Central European University in Budapest, Hungary. His books include From Dissident to Party Politics: The Struggle for Democracy in Post-Communist Hungary (2007). Bear in mind that not everyone shares Orbán’s vision of what will make this nation great, again. On graffiti-covered walls in Budapest, Runes (traditional Hungarian script) has been found that read “Orbán is a motherfucker” (Mikanowski, 2019, 58). Also in Europe, in Chapter 6, Professor Ronan Le Coadic, of the University of Rennes, Rennes, France, in “Is There a Revival of French Nationalism?” Stating this title in the form of a question is quite appropriate because France’s nationalistic shift has built and ebbed several times during the last few decades. For a time after 2000, it came close to assuming the role of a substantial minority, only to ebb after that. In 2017, the candidate of the National Front reached the second round of the French presidential election. This was the second time this nationalist party reached the second round of the presidential election in the history of the Fifth Republic. In 2002, however, Jean-Marie Le Pen had only obtained 17.79% of the votes, while fifteen years later his daughter, Marine Le Pen, almost doubled her father's record, reaching 33.90% of the votes cast. Moreover, in the 2019 European elections, re-named Rassemblement National obtained the largest number of votes of all French political formations and can therefore boast of being "the leading party in France.” The brutality of oppressive nationalism may be expressed in personal relationships, such as child abuse. While Indonesia and Aotearoa [the Maoris’ name for New Zealand] hold very different ranks in the United Nations Human Development Programme assessments, where Indonesia is classified as a medium development country and Aotearoa New Zealand as a very high development country. In Chapter 7, “Domestic Violence Against Women in Indonesia and Aotearoa New Zealand: Making Sense of Differences and Similarities” co-authors, in Chapter 8, Mandy Morgan and Dr. Elli N. Hayati, from New Zealand and Indonesia respectively, found that despite their socio-economic differences, one in three women in each country experience physical or sexual intimate partner violence over their lifetime. In this chapter ther authors aim to deepen understandings of domestic violence through discussion of the socio-economic and demographic characteristics of theit countries to address domestic violence alongside studies of women’s attitudes to gender norms and experiences of intimate partner violence. One of the most surprising and upsetting scholarly journeys that a North American student may take involves Adolf Hitler’s comments on oppression of American Indians and Blacks as he imagined the construction of the Nazi state, a genesis of nationalism that is all but unknown in the United States of America, traced in this volume (Chapter 8) by co-editor Johansen. Beginning in Mein Kampf, during the 1920s, Hitler explicitly used the westward expansion of the United States across North America as a model and justification for Nazi conquest and anticipated colonization by Germans of what the Nazis called the “wild East” – the Slavic nations of Poland, the Baltic states, Ukraine, and Russia, most of which were under control of the Soviet Union. The Volga River (in Russia) was styled by Hitler as the Germans’ Mississippi, and covered wagons were readied for the German “manifest destiny” of imprisoning, eradicating, and replacing peoples the Nazis deemed inferior, all with direct references to events in North America during the previous century. At the same time, with no sense of contradiction, the Nazis partook of a long-standing German romanticism of Native Americans. One of Goebbels’ less propitious schemes was to confer honorary Aryan status on Native American tribes, in the hope that they would rise up against their oppressors. U.S. racial attitudes were “evidence [to the Nazis] that America was evolving in the right direction, despite its specious rhetoric about equality.” Ming Xie, originally from Beijing, in the People’s Republic of China, in Chapter 9, “News Coverage and Public Perceptions of the Social Credit System in China,” writes that The State Council of China in 2014 announced “that a nationwide social credit system would be established” in China. “Under this system, individuals, private companies, social organizations, and governmental agencies are assigned a score which will be calculated based on their trustworthiness and daily actions such as transaction history, professional conduct, obedience to law, corruption, tax evasion, and academic plagiarism.” The “nationalism” in this case is that of the state over the individual. China has 1.4 billion people; this system takes their measure for the purpose of state control. Once fully operational, control will be more subtle. People who are subject to it, through modern technology (most often smart phones) will prompt many people to self-censor. Orwell, modernized, might write: “Your smart phone is watching you.” Ming Xie holds two Ph.Ds, one in Public Administration from University of Nebraska at Omaha and another in Cultural Anthropology from the Chinese Academy of Social Sciences, Beijing, where she also worked for more than 10 years at a national think tank in the same institution. While there she summarized news from non-Chinese sources for senior members of the Chinese Communist Party. Ming is presently an assistant professor at the Department of Political Science and Criminal Justice, West Texas A&M University. In Chapter 10, analyzing native peoples and nationhood, Barbara Alice Mann, Professor of Honours at the University of Toledo, in “Divide, et Impera: The Self-Genocide Game” details ways in which European-American invaders deprive the conquered of their sense of nationhood as part of a subjugation system that amounts to genocide, rubbing out their languages and cultures -- and ultimately forcing the native peoples to assimilate on their own, for survival in a culture that is foreign to them. Mann is one of Native American Studies’ most acute critics of conquests’ contradictions, and an author who retrieves Native history with a powerful sense of voice and purpose, having authored roughly a dozen books and numerous book chapters, among many other works, who has traveled around the world lecturing and publishing on many subjects. Nalanda Roy and S. Mae Pedron in Chapter 11, “Understanding the Face of Humanity: The Rohingya Genocide.” describe one of the largest forced migrations in the history of the human race, the removal of 700,000 to 800,000 Muslims from Buddhist Myanmar to Bangladesh, which itself is already one of the most crowded and impoverished nations on Earth. With about 150 million people packed into an area the size of Nebraska and Iowa (population less than a tenth that of Bangladesh, a country that is losing land steadily to rising sea levels and erosion of the Ganges river delta. The Rohingyas’ refugee camp has been squeezed onto a gigantic, eroding, muddy slope that contains nearly no vegetation. However, Bangladesh is majority Muslim, so while the Rohingya may starve, they won’t be shot to death by marauding armies. Both authors of this exquisite (and excruciating) account teach at Georgia Southern University in Savannah, Georgia, Roy as an associate professor of International Studies and Asian politics, and Pedron as a graduate student; Roy originally hails from very eastern India, close to both Myanmar and Bangladesh, so he has special insight into the context of one of the most brutal genocides of our time, or any other. This is our case describing the problems that nationalism has and will pose for the sustainability of the Earth as our little blue-and-green orb becomes more crowded over time. The old ways, in which national arguments often end in devastating wars, are obsolete, given that the Earth and all the people, plants, and other animals that it sustains are faced with the existential threat of a climate crisis that within two centuries, more or less, will flood large parts of coastal cities, and endanger many species of plants and animals. To survive, we must listen to the Earth, and observe her travails, because they are increasingly our own.

The thermoregulation mechanisms during the physical effort can be easily study by using the thermovision. The thermoregulation mechanisms in human body keep the body core temperature on basic level 37 ± 2oC. However, the question is if there are any differences in skin surface temperature distribution between trainee sportsmen and amateur. Is there any possibility to show the sportsman level of practise using the thermal imaging? Would it be possible to evaluate the efficiency of athlete or evaluate the level of sports possibilities in average amateur who just wants to start cycle training. To find how the thermoregulation mechanisms work the different measurements were done i.e. during the cyclist endurance test for group of male cyclist (intermediate level of cycling skill) and during the Aerobic Circuit Training (ACT) for trainee and amateur group of women.

Ultrasonic material characterization or inspection for defects is conventionally performed using either liquid coupling (water, usually) or some type of gel or oil in contact-mode coupling. Mechanical waves can be transmitted only through some sound-supporting medium from their source (a transducer) to the object under study, and back again. Using distilled, degassed water to couple ultrasound to an object under test works quite well and has many technical advantages, including relatively low signal loss over laboratory or shop dimensions at typical frequencies, almost zero toxicity, and low cost. For many applications, the use of water is acceptable and preferred. There are, however, certain testing applications for which water can be a disadvantage. These situations include materials that are sensitive to contact with water, such as uncured graphite-epoxy composites or certain electronics. Large objects, whose total immersion is impractical, or objects for which rapid scanning is required might also be unsuitable for water coupling. Recent technological developments are beginning to permit the judicious replacement of water by a far more ubiquitous sound coupling medium—air. Ultrasonic testing in air has been investigated for more than 30 years, but recently there has been an upsurge in interest and application because of the availability of much more efficient sound-generating devices designed specifically for operation in air. In water- or direct-coupled ultrasonics, one typically employs piezoelectric transducers to generate sound waves because they are well suited to the generation of sound in water or in solids because of their high acoustic impedance. In air, however, we need just the opposite. Air is very compliant, so waves from a high-impedance source couple poorly into air. Much effort has been invested in finding suitable impedance matching materials that will render the familiar piezoelectric probe efficient in air-coupled (A-C) ultrasound. The problem, however, is nearly insurmountable because of the large acoustic impedance difference between air and quartz, for example. Quartz has an acoustic impedance of about 15 MRayl, while air’s impedance is about 425 Rayl, a ratio of about 35,000. The challenge is to find a material with an acoustic impedance that nearly equals the geometric average of these two widely disparate values.

At all taxonomic levels, there exists tremendous variation in life expectancy. A field mouse Peromyscus may live 1.2 years, while the African elephant may persist for 60 years, and even a mousesized bat such as Corynorhinus rafinesquei lives a healthy 20 years (Promislow 1991). Part of this variance is caused by differences in ecological risks, rodents being perhaps the most susceptible to predation, and to vagaries of climate and resources. Another portion is caused by differences in senescence, the intrinsic degeneration of function that produces progressive decrement in age-specific survival and fecundity. Senescence occurs in natural populations, where it affects life expectancy and reproduction as can be seen, for instance, from the progressive change in age-specific mortality and maternity of lion and baboon in East Africa. The occurrence of senescence and of the widespread variation in longevity presents a paradox: How does the age-dependent deterioration of fitness components evolve under natural selection? The conceptual and empirical resolutions to this problem will be explored in this chapter. We shall see that the force of natural selection does not weigh equally on all ages and that there is therefore an increased chance for genes with late-age-deleterious effects to be expressed. Life histories are expected to be optimized to regulate intrinsic deterioration, and in this way, longevity evolves despite the maladaptive nature of senescence. From this framework, we will then consider how the model is tested, both through studies of laboratory evolution and of natural variation, and through the physiological and molecular dissection of constraints underlying trade-offs between reproduction and longevity. As humans are well aware from personal experience, performance and physical condition progressively deteriorate with adult age. And in us, as well as in many other species, mortality rates progressively increase with cohort age. Medawar (1955), followed by Williams (1957), stated the underlying assumption connecting these events: Senescent decline in function causes a progressive increase in mortality rate. Although mortality may increase episodically across some age classes, such as with increases in reproductive effort, we assume that the continuous increase of mortality across the range of adult ages represents our best estimate of senescence.

The progressive ageing of populations leads to a high burden of elderly patients with cardiac disease and is associated with comorbidities, cognitive/psychological deterioration, disability, social deprivation, and frailty. All these conditions complicate the clinical course of cardiac disease and worsen the outcome. Cardiac rehabilitation (CR), as a multidisciplinary intervention, improves mortality, morbidity, re-hospitalization, physical function, and quality of life in adult patients after acute cardiac events. Older patients without clinical complexity can follow a CR programme slightly different from that for middle-aged patients, mainly based on aerobic training, with similar functional improvement. CR for elderly cardiac patients with comorbidities, sarcopenia, or frailty should be based mainly on strength exercise integrated with aerobic and balance training, but the most appropriate exercise programme has yet to be defined. Future studies should test whether interventions tailored to the presence and severity of frailty are effective in improving specific outcomes, with particular reference to functional capacity, physical function, health-related quality of life (HQoL), disability, frailty, hospitalization, and institutionalization.

Cardiovascular disorders remain one of the commonest causes of ill health and death but their incidence in Western society has been declining and there have also been significant reductions in death rates due to major advances in treatment over the last 20 years. Cardiovascular disease (CVD) affects working-age people and occupational physicians will see it regularly in the clinic. It affects fitness to work in two ways. First, an individual may suffer from symptoms on effort that limit their working capacity. Such disability is quantifiable and can often be alleviated by effective treatment. The second less common but more difficult problem is the risk of sudden incapacity, especially in individuals who appear well. This may occur for a variety of reasons including the risk of sudden cardiac death following ventricular fibrillation and whilst the instantaneous risk of sudden incapacity is very small, the consequences can be unacceptable. Assessment of this risk and its impact is possible in populations but explaining this concept to a bus driver who has lost his job is not easy. Limitation of working capacity and the risk of sudden incapacity can be well judged in populations by specialist opinion. For the individual this must be backed up by objective data, usually derived from the results of non-invasive tests such as electrocardiography (ECG) and exercise testing. Whilst disease progression can be unpredictable the use of objective data can ensure the individual is not unfairly excluded from work they can safely do. Sometimes cardiovascular symptoms are out of all proportion to the objective evidence of disease. This may arise from psychological disturbance following the development of CVD which in itself is associated with a high rate of common mental health problems. A heart attack proves devastating and the patient never returns to work despite prompt treatment, a full cardiac recovery, and only modest residual disease. The occupational physician needs to recognize the mental health problems associated with CVD and ensure that all treatment options are considered to facilitate rehabilitation to the workplace.

Smart territories favor social entrepreneurship, which develops in a collaborative effort requiring networking and skilled facilitation. Coworking spaces (CWS) advance as mediating organizations that bring together entrepreneurial communities in smart territories. This chapter develops a practical framework for knowledge dissemination in CWS. It bases this framework on the analysis of three spatial characteristics that allow for the assessment of the knowledge transcendence originating in CWS, namely, physical, social, and informational spaces. To test this framework, the authors analyze the Roma-Norte corridor in Mexico City, whose results indicate the presence of two models: one constituted of private organizations that place collaboration as a secondary value, subject to their office rental services, and an umbrella model that clusters other social innovation facilitators that transcend their territorial strip. This latter meta-space model expresses positive effects in terms of knowledge spillover, suggesting the concentrated bottom-up construction process of a smart territory.

Quadrotor control is an exciting research area. Despite last years developments, some aspects demand a deeper analysis: How a quadrotor operates in challenging trajectories, how to define trajectory limits, or how changing physical characteristics of the device affects the performance. A visual interface development platform is a valuable tool to support this effort, and one of these tools is briefly described in this Chapter. The quadrotor model uses Newton-Euler equations with Euler angles, and considers the effect of air drag and propellers’ speed dynamics, as well as measurement noise and limits for propeller speeds. The tool is able to test any device just by setting a few parameters. A three-dimensional optimal trajectory defined by a set of waypoints and corresponding times, is calculated with the help of a Minimum Snap Trajectory planning algorithm. Small Angle Control, Desired Thrust Vector (DTV) Control and Geometric Tracking Control are the available strategies in the tool for quadrotor attitude and trajectory following control. The control gains are calculated using Particle Swarm Optimization. Root Mean Square (RMS) error and Basin of Attraction are employed for validation. The tool allows to choose the control strategy by visual evaluation on a graphical user interface (GUI), or analyzing the numerical results. The tool is modular and open to other control strategies, and is available in GitHub.

<em>Abstract.</em>—Described in this paper are my experiences with, and reflections on, managing salmon for 30 years with the Oregon Department of Fish and Wildlife. Specifically, I will focus on lessons learned from Oregon’s struggle to effectively manage coho salmon <em>Oncorhynchus kisutch </em>in Oregon’s coastal streams. In the 1980s–1990s, salmon managers discovered that the fishery management strategies were based on false assumptions regarding the capability of freshwater habitat to produce smolts, the constancy of ocean productivity, and the role of hatchery fish in coastal ecosystems. As managers, we misinterpreted spawning stock assessment data and stock-recruitment relationships, an error which, when combined with a pressing need to harvest returning hatchery fish, led to overly aggressive harvest strategies that drove the less productive stocks of Oregon’s wild coastal coho salmon toward extinction. A progressive research program helped identify these errors and the new information generated through this research program helped fishery managers re-formulate management strategies to meet changing threats to coho salmon. As a result, federal listing of Oregon’s coastal coho salmon stocks under the Endangered Species Act was avoided. The successful conservation and harvest of coho salmon stocks in the 1970s led to complacency among fishery managers, which then subtly shifted into arrogance over time. This shift caused managers to be slow to recognize the changes occurring in the ecosystem. Managers must not become complacent or arrogant in their abilities to manage; they must look for potential surprises and must be ready to respond to future challenges and threats to salmon. Three major lessons from were learned from the author’s experiences with Oregon’s coastal coho salmon. Lesson number one—be careful about the use of stock recruitment relationships in management. Meeting the minimum escapement goals does not mean that harvesting the rest of the population is a wise or sustainable practice. Lesson number two—carefully consider planting locations for hatchery fish, and how stocking locations and practices will change the distribution of fishing effort and affect fishing mortality of wild fish and confuse assessment indices. Lesson number three—challenge your assumptions under which you are managing. Conduct the research required to test your assumptions, and change management strategies when necessary. The two big future challenges facing coho salmon are the increasing size of human populations and predicted warming of the climate along Oregon’s coast. The lessons learned over the past 30 years should be applied to future challenges to ensure the sustainability of salmon.

Abstract The objective of this study is to predict ceramic matrix composites (CMCs) erosion behavior and Retained Strength (RS) under environmental conditions using an Integrated Computational Material Engineering (ICME) physics-based approach. The state-of-the-art erosion analysis using phenomenological algorithms and Finite Element Models (FEM) models follows a test duplication methodology and is not able to capture the physics of erosion. In this effort, two CMC systems are chosen for Erosion evaluation: (a) Oxide/Oxide N720/alumina; and (b) MI SiC/SiC. Experiments are conducted at room and elevated temperatures (RT/ ET). Erosion testing considers: (i) a high velocity oxygen fuel (HVOF) burner rig for ET, and (ii) a pressurized helium impact gun for RT. Erodent particles are chosen as alumina and garnet. Experimental observations show that the type of erodent materials affects CMC erosion degradation at ET. Alumina exhibits to be an effective erodent for maintaining a solid phase particle erosion, while Garnet, experiences some degree of melting. Erosion of the oxide/oxide composite is more severe for the same erodent, temperature, mass, and velocity conditions than the MI SiC/SiC composite for all conditions tested. In general, increasing erosion temperature results in increasing erosion rate for the same erodent mass/velocity condition. In conjunction with experiments, a computational Multi-Scale Progressive Failure Analysis (MS-PFA) is also used to predict erosion of the above-mentioned material systems at RT/ET. The MS-PFA augments FEM by a de-homogenized material modeling that includes micro-crack density, fiber/matrix, interphase, and degrades both fiber and matrix simultaneously during the erosion process. Erodent particles are modeled by Smooth Particle Hydrodynamic (SPH) elements. Erosion evolution in CMCs considering strain rate effect predicts a) spallation, b) mass-loss, and c) damages in fiber, matrix, and their interphase. ICME modeling is capable of predicting the erosion process and reproducing the test observation for the MI SiC/SiC at RT, where: a) erodent particles break up the layer of matrix covering fiber due to interlaminar shear (delamination); b) fiber is fractured because of brittle behavior; c) the process (erosion tunneling) continues till it gets to the next thick matrix layer that slows down the tunneling; and d) Erosion tunnel widens as exposed fiber layers are removed (eroded). Simulations are also performed for erosion of the oxide/oxide due to glass beads at RT and ET. Predictions show that erosion rate is lower at ET because voids in the CMC vanish and the glass beads are less effective at ET. Finally, prediction of retained strength of eroded CMC test specimens is predicted by MS-PFA.

This study aims to further promote the understanding of the antecedents of the acceptance and use of digital wellness technologies among elderly people through a follow-up to our two prior studies, one which examines the potential longer-term temporal changes in the use intention of digital wellness technologies and its antecedents in the case of the young elderly segment and physical activity logger applications. We base this examination theoretically on UTAUT2 and empirically on survey data that is collected from 92 Finnish young elderly users of a physical activity logger application in three subsequent time points and analysed with partial least squares structural equation modelling (PLS-SEM). We find that the initial strong decline in the scores of the antecedent constructs and use intention becomes weaker as the construct scores stabilise over time, whereas especially the effects of performance expectancy and effort expectancy on use intention remain relatively unstable.

Physical interaction with tools is ubiquitous in functional activities of daily living. While tool use is considered a hallmark of human behavior, how humans control such physical interactions is still poorly understood. When humans perform a motor task, it is commonly suggested that the central nervous system coordinates the musculo-skeletal system to minimize muscle effort. In this paper, we tested if this notion holds true for motor tasks that involve physical interaction. Specifically, we investigated whether humans minimize muscle forces to control physical interaction with a circular kinematic constraint. Using a simplified arm model, we derived three predictions for how humans should behave if they were minimizing muscular effort to perform the task. First, we predicted that subjects would exert workless, radial forces on the constraint. Second, we predicted that the muscles would be deactivated when they could not contribute to work. Third, we predicted that when moving very slowly along the constraint, the pattern of muscle activity would not differ between clockwise (CW) and counterclockwise (CCW) motions. To test these predictions, we instructed human subjects to move a robot handle around a virtual, circular constraint at a constant tangential velocity. To reduce the effect of forces that might arise from incomplete compensation of neuro-musculo-skeletal dynamics, the target tangential speed was set to an extremely slow pace (∼1 revolution every 13.3 seconds). Ultimately, the results of human experiment did not support the predictions derived from our model of minimizing muscular effort. While subjects did exert workless forces, they did not deactivate muscles as predicted. Furthermore, muscle activation patterns differed between CW and CCW motions about the constraint. These findings demonstrate that minimizing muscle effort is not a significant factor in human performance of this constrained-motion task. Instead, the central nervous system likely prioritizes reducing other costs, such as computational effort, over muscle effort to control physical interactions.

Less than 15 years ago the National Heart, Lung and Blood Institute surveyed physicians in the United States in order to characterize the demographics of hemophilia. The average age of persons with hemophilia in the United States was found to be 11.5 years old. By 10 years later, the life expectancy was predicted to be normal, and indeed the average age of persons with hemophilia in the U.S. is now in the early twenties. Early, intensive and predictably efficacious control of hemorrhage has made this result possible, and the therapeutic product which has allowed such control is commercial clotting factor concentrate.We now know that starting in 1978, and with great frquency during 1982 and 1983, the majority of U.S. hemophiliacs were infected with human immunodeficiency virus (HIV). It is estimated that as of January, 1987, approximately two thirds of the 20,000' persons with hemophilia in the United States have been infected with HIV. Among those with severe factor VIII deficiency, more than 9056 are seropositive. As of 1/5/87, there were 288 cases of AIDS among U.S. hemophiliacs, for an AIDS rate of approximately 2.256 of those with HIV infection. This number included 185 with severe, 32 with moderate and 28 with mild hemophilia A; 12 with severe, 6 with moderate and 1 with mild hemophilia B; 9 with vWD, and 4 others. A disproportionate number were older patients: 55 were ages 1-19; 62 ages 20-29; 85 ages 30-39, and 86 age 40 or older. Although the AIDS attack rate is no longer climbing logarhythmically, new cases are certainly still occurring.A variety of other HIV-related syndromes have emerged. Of great concern is immune thrombocytopenia, which is now relatively common; among a group of 209 carefully followed HIV-positive patients at our center, 31 (1556) are or have been thrombocytopenic. Progressive failure to normally gain height and weight in children with hemophilia has recently been shown by our group to correlate with HIV antibody positivity, and also with decreased T4/T8 ratio, decreased T4 cell count, decreased skin test reactivity, and subsequent development of ARC or AIDS in some such children. Finally, a picture of progressive fall in T4 count associated with recurrent non-specific infections and increased likelihood of positive viral culture, may predict an increased risk of developing AIDS.We know that the immune dysfunction in hemophilia is complex, and not wholly explained by HIV infection. One important factor may be the many foreign proteins contained in commercial clotting factor concentrates, and their ability to stimulate T cells. It is known that latent HIV infection in cultured T4 lymphocytes can be induced to enter the proliferative, viral secretory phase by the addition of soluble foreign antigens to the cell culture. Recent data of Brettler and colleagues, to be presented at this meeting, suggest that the use of highly purified VI!I:C (specific activity >3000 u/mg) in place of the present extremely impure products, may improve the immune dysfunction in hemophilia. This observation offers a new hypothetical approach to the prevention of progressive T4 cell depletion in HIV infected hemophiliacs, and requires immediate and extensive further study.The psychosocial burden of HIV infection is immense. The need for extensive, formal education and support programs is largely unmet in most parts of the world. Such programs are best run out of hemophilia treatment centers in most cases, and must include an active program on prevention of sexual transmission, provision of HIV testing before and during pregnancies, provision for maintenance of confidentiality, etc. Education concerning HIV is like all other forms of education. It requires formal organization, a curriculum, active rather than passive learning in which there is interaction between the teacher and the pupil, time for planned repetition, reinforcement with written materials, and assessment of goals achieved. For all of these reasons it is inappropriate to assume that the physician at the hemophilia center will be able to provide an adequate education program. Adquate paramedical personnel will need to undertake this effort, under the directjon of the physician.

Harnessing the power of ocean waves offers enormous potential as a source of renewable energy. To date the technologies for capturing this resource, collectively known as wave energy converters (WECs), have yet to reach commercial viability and continued research and development efforts are required to move wave energy to the industrial scale. Integral to this process is ensuring that technologies progress along a staged development pathway; proving WEC concepts using small scale physical models in controlled settings such as laboratory wave tanks before eventually advancing to testing sub-prototype and full scale devices in real sea conditions. The primary objective of this research is to improve the understanding of how best to address the scaling of wave resource measurements and wave energy device power production when analyzing the results of sea-trials. This paper draws on measured data from three test sites; Galway Bay in Ireland, the Pacific Marine Energy Test Centre off the coast of Oregon, and Lake Washington, and assesses how accurately they recreate, at reduced scale, the conditions that commercial WEC installations are likely to encounter at exposed deployment locations. Appropriate techniques for extrapolating these results to predict the performance of commercial WECs at energy-rich locations on the west coasts of Ireland and the US are also demonstrated and discussed. The output from this research will be a set of protocols for addressing wave energy resource scalability to help guide device developers through this important stage of technology progression. Improved knowledge regarding resource scalability will allow for more streamlined progression of WEC concepts from wave tanks to sea-trials, and eventually to full-scale ocean deployment. It will also result in a reduced uncertainty about device power output and survivability, which are key drivers in determining the economic viability of projects.

Technical systems must be continuously improved so that they can remain competitive on the market. Also, the time-to-market is an important factor for the success of a product. To achieve this goal, new methods and processes are needed. Especially the testing and calibration are important phases in the development process. This paper introduces a method, which helps to reduce the time effort while increasing the quality of the calibration process. The basic idea is to use measured test data to parameterize a physical (or mostly physical) model structure to create adequate models for the optimization. The main advantage of the method is the reduction of test effort because the number of variations of the design parameter is one, or extremely decreased (depending on the system). Another advantage is that the uncertainty and the limit of the model can be quantified more accurately compared to common approaches based on non-physical model structures. These normally use artificial neuronal networks (ANN) or polynomial approaches for the test-based optimization. This contribution illustrates the method by using the example of the calibration process of a double clutch gearbox (DCT) regarding energy efficiency and drivability on a roller test bench. First step is the test planning and test execution. In this step the method calculates the optimal execution order of the measuring points. In this example 81% timesaving can be achieved compared to the equivalent on the test track. The second step is the automated generation of the simulation model. In this step the unknown parameters of the model structure are calculated. The contribution shows different approaches for the identification of non-linear systems. In the last step the model is used to perform the optimization of the design parameters.

Tidal energy has received increasing attention over the past decade. This increasing focus on capturing the energy from tidal currents has brought about the development of many designs for tidal current turbines. Several of these turbines are progressing rapidly from design to prototype and pre-commercial stages. As these systems near commercial development, it becomes increasingly important that their performance be validated through laboratory tests (e.g., towing tank tests) and sea tests. Several different turbine configurations have been tested recently. The test results show significant differences in turbine performance between laboratory tests, numerical simulations, and sea tests. Although the mean velocity of the current is highly predictable, evidence suggests a critical factor in these differences is the unsteady inflow. To understand the physics and the effect of the inflow on turbine performance and reliability, Verdant Power (Verdant) and the National Renewable Energy Laboratory (NREL) have engaged in a partnership to address the engineering challenges facing marine current turbines. As part of this effort, Verdant deployed Acoustic Doppler Current Profiler (ADCP) equipment to collect data from a kinetic hydropower system (KHPS) installation at the Roosevelt Island Tidal Energy (RITE) project in the East River in New York City. The ADCP collected data for a little more than one year, and this data is critical for properly defining the operating environment needed for marine systems. This paper summarizes the Verdant-NREL effort to study inflow data provided by the fixed, bottom-mounted ADCP instrumentation and how the data is processed using numerical tools. It briefly reviews previous marine turbine tests and inflow measurements, provides background information from the RITE project, and describes the test turbine design and instrumentation setup. This paper also provides an analysis of the measured time domain data and a detailed discussion of shear profiling, turbulence intensity, and time-dependent fluctuations of the inflow. The paper concludes with suggestions for future work. The analysis provided in this paper will benefit future turbine operation studies. In addition, this study, as well as future studies in this topic area, will be beneficial to environmental policy makers and fishing communities.

An approach to increasing sensor performance and detection reliability for buried objects is to better understand which physical processes are dominant under certain environmental conditions. The present effort (Phase 2) builds on our previously published prior effort (Phase 1), which examined methods of determining the probability of detection and false alarm rates using thermal infrared for buried-object detection. The study utilized a 3.05 × 3.05 m test plot in Hanover, New Hampshire. Unlike Phase 1, the current effort involved removing the soil from the test plot area, homogenizing the material, then reapplying it into eight discrete layers along with buried sensors and objects representing targets of inter-est. Each layer was compacted to a uniform density consistent with the background undisturbed density. Homogenization greatly reduced the microscale soil temperature variability, simplifying data analysis. The Phase 2 study spanned May–November 2018. Simultaneous measurements of soil temperature and moisture (as well as air temperature and humidity, cloud cover, and incoming solar radiation) were obtained daily and recorded at 15-minute intervals and coupled with thermal infrared and electro-optical image collection at 5-minute intervals.

This report describes the results of technical analysis, field tests, and laboratory tests that were performed for LED highway lighting options by the Energy Efficiency and Reliability Center (EERC) at Purdue University Northwest for the Indiana Department of Transportation (INDOT). This effort was conducted over the past 3 years to evaluate and test the technology and viability of using modern highway lighting technology to enhance energy efficiency, safety, security, and economic development of communities and roadways. During the testing period there was a continuous discussion between INDOT and EERC regarding the laboratory and field testing of INDOT approved luminaires submitted by vendors. There were multiple discussions with INDOT and vendors regarding the individual details and issues for the 29 luminaires that were tested. A comparison study was conducted by EERC of the various alternatives and comparison to currently installed luminaires. Data was collected for field tests of the luminaires by EERC and INDOT personnel for the luminaires. Field data was evaluated and compared to lighting models using vendor supplied ies data files. Multiple presentations were made at 3 separate Purdue Road Schools regarding the results and procedures of the testing program by EERC in conjunction with INDOT. A total of 22 final reports, considered confidential by INDOT, for individual vendor luminaires have been prepared as part of this effort. These reports were submitted sequentially to INDOT as testing was completed during the course of this effort. A total of 29 luminaires were tested. Some luminaire testing was terminated during testing due to design issues or vendor requests. All testing was summarized in the INDOT specification sheet attached to each report. Observations regarding the consistency of the supplied test luminaire with the requirements of Section 7.2 of the INDOT test procedure “Procedure for evaluation and approval list requirements for solid state ballasted luminaires ITM 957-17P” is provided in the Appendix to the report for each luminaire. Details regarding how these tests were performed and the respective associated evaluation of performance and reliability are provided in the report. This effort included: consideration of published and vendor information; appraisal of products consistent with national industry standards; review of physical design, thermal performance; laboratory testing of photopic performance, reliability, life cycle data and characteristics, and power characteristics; technical and probabilistic risk studies; and field testing and analysis of LED light sources including comparison to currently installed conventional light sources. Assistance in preparing INDOT standards for highway lighting was provided on multiple occasions.
