Coordination is a key element in emergency response. This paper focuses on coordination as it occurred in a county-level Emergency Operations Center (EOC) during a simulated tornado. The EOC is responsible for locating, purchasing, and transporting resources to the disaster scene(s). The EOC is an ad hoc team made up of government agencies, private companies (i.e., hospitals, utilities, etc.), and non-governmental agencies. These decision makers come together to engage in creative problem solving in order to solve often complex logistics and coordination problems generally under intense time pressure during a rapidly evolving situation. Lessons learned from this exercise highlight coordination challenges including asymmetric information flow, natural fault lines, roles and functions, co-location benefits, emergent leadership, fragmented situation awareness, information displays, room design, and quick reference tools.

COVID-19 is a disease caused by coronavirus; it is also called a SARS-COV-2 virus. Over the last six months, it has spread rapidly worldwide and made it a pandemic. The pandemic has forced people to stay indoors and work, which may increase chronic diseases among them. Immunomodulators are the substances which influence the immune system. It includes some medications as well as some activities like exercise, Yoga, meditation etc. Elderly citizens who used to walk generally before lockdown may suffer from pedestrian problems including hyperthyroidism, sugar problems blood. When the media used to do the work regularly, we had one kind of stress to do all the desired or targeted work on time. But now the person became very lazy due to self-reliant schedule that may lead to many diseases. So physical exercise is essential in this pandemic situation. Physical activity results in better immune response, which may result in many health benefits. An individual who regularly does physical exercises is healthy and fit in every aspect that can beat any of the diseases. It can also refine cardiovascular risk factor. In addition to this, it also enhances - pro thrombogenesis, improves endothelial functions, increases inculcation, depletes sympathetic tone and some other undefined factors. But all these have been put at bay due to Covid-19 pandemic. It is challenging to keep up an exercise routine due to daily restricted movements. Physical exercise helps in boosting the immune system of our body which reduces stress, anxiety. Brain gets the supplement of endorphins, chemicals that revitalise one's mind and body enriching the mental and spiritual faculty of an individual.

ABSTRACT Introduction: The main reason for the decline in college students’ physical fitness and health is the lack of physical exercise, the emphasis on study and the neglect of physical exercise, and the lowering of the physical fitness requirements of college students. Objective: The paper analyzes the status quo and existing problems of college students’ physical fitness and proposes that the school party committee issues policy-based health intervention measures, encourages school physical education teachers to participate in students’ after-school physical exercises, and extensively develops school mass sports activities. Methods: The paper uses a literature method, questionnaire survey, comprehensive evaluation method, etc., to analyze the internal and external factors of college students’ physical decline. Results: Through the practice density test of students in physical education teaching, it is learned that physical education in the first grade can fully develop students’ physical fitness, and the practice density of each class reaches 60%. The practice density of the second-grade optional courses is about 20%, and it cannot achieve the purpose of effective physical exercise. Conclusions: The current teaching content and teaching methods of physical education classes cannot effectively complete physical education tasks. It is necessary to adjust the teaching content further and improve the teaching methods. Level of evidence II; Therapeutic studies - investigation of treatment results.

The paper is devoted to the problems concerning the legal nature, normative regulation and the procedure for the implementation of the institute of preliminary constitutional review in the Russian Federation. Although the exercise of this type of constitutional control ensurs the prevention of the detected violations, it also carries certain risks associated with the limited time frame of its implementation, impossibility of taking into account interpretation of the contested norm in law enforcement, etc. The author demonstartes permissible forms of the use of preliminary control in the activity of the bodies of constitutional justice in Russia (when checking the constitutionality of international agreements and treaties of the Russian Federation, evaluating constitutional amendments, etc.). The author also investigates the practice of implementing the relevant powers. Particular attention is paid to the analysis of the legal positions of the Constitutional Court of the Russian Federation that stipulate the limits of the implementation of preliminary judicial constitutional review. The paper examines the issue of the powers of constitutional (charter) courts of constituent entities of the Russian Federation in the area under consideration.

Background: Urinary incontinence is defined as the complaint of involuntary loss of urine. It is a common and embarrassing problem. Pelvic floor muscle training has been effective for the prevention and treatment of urinary incontinence during pregnancy and after childbirth. Thus, the aim of this study is to explore the effectiveness & outcome of physiotherapy in pelvic floor muscle training during pregnancy & childbirth in urinary incontinence. Methodology: In this scoping review articles are searched from the search engines like PUBMED, GOOGLE SCHOLAR, etc. These articles are reviewed according to the inclusion criteria which include articles from last 10 years, randomized control trials, systematic review, experimental study, etc. 7 articles were selected according to it. Later the qualities of these articles were analyzed using PEDRO Scale. Conclusion: In conclusion our study demonstrates that the pelvic floor muscle training might be effective in solving the problems of urinary incontinence during pregnancy and after childbirth. Pelvic floor muscle training can be advised by the physiotherapist or the pregnant women can be trained on how to perform the pelvic floor muscle exercises. Thus, pregnant women can take care of themselves and independently perform pelvic floor muscle exercises, thereby eliminating the problems of urinary incontinence. Key words: Pelvic Floor Muscle Training, Pregnancy, After Childbirth, Prevention, Treatment, Urinary Incontinence.

Military personnel are in high-risk group for health disorders, musculoskeletal pathology and psychological overload. We provide evaluation of the anthropometric parameters and health status of military personnel, Cadets, who have participated in ten days duration Combat training course. Combat training course is associated with life-style change – social, environmental, climate and geographical conditions, biorhythms, nutrition etc., with an increase in physical and psych emotional loads. It is characterized with transition from daily routine of military study process in National Defence academy to military exercise in external environment. Cadets faced to feeding limitation, sleeping deprivation intensive and continuous training, strict discipline etc. We provided analysis of anthropometric parameters before, and in time of Combat training course, summarized data of health statement and health problems that were fixed in the medical cards. The proper body mass supports good health capacity and we provided assessment of it. Physical fitness and body composition have adverse effect on military performance. Body composition undergoes changes during higher physical load performance. Military personnel have high risk to health, concerning impact of external and internal factors. According the review of medical cards of cadets group, we indicated main problems, which are fixed after the Combat training course.

The authors propose a web-based system to support students' homework, and letting their parents have access to it. From the teacher's point of view, the authors believe that one of the major advantages of their system is time saving. Like other systems available, this system gathers statistical data concerning different groups of students selected by the teacher. From these data on, the teacher can easily see where students are having problems and decide what to do next. From the student's point of view, the authors elected as main advantages of this system the prompt feedback about the exercises correctness, added to the training with different exercises sets about the same subject, besides the utilization of video, color, sound, etc., that positively reinforce child's senses. Their previous results show that students prefer to solve exercises in digital form, rather than exercises in paper form, also showing a more positive attitude towards the former. Also, the authors have seen that the use of computers has enabled the development of tactile sensitivity and motor coordination in children with special education needs.

The article discusses a new strategy of professionally-directed (didactic-oriented) foreign language teaching to students of a language pedagogical university (future teachers of a foreign language). The study analyses the components of the teacher’s methodological (linguodidactic) competence, revealing a number of problems concerning their formation in a pedagogical university, as well as showing the dependence of their development on the intensity of their actualisation in the Foreign Language Practice discipline. The article identifies several factors hindering the formation of the linguodidactic competence within foreign language classes. In order to overcome these negative factors, the article offers a new model of teaching foreign languages, described in the formula “from the acquisition of didactic experience to one’s own educative decisions”. The methodology of this model is based on two interrelated methods: contextual teaching and vocation-focused foreign languages teaching, as well as related methods for organizing productive teaching of a foreign language. The model mentioned above assumes a two-stage implementation. At the first stage, analytical work of students is organized. Its aim is to understand and analyse the teaching practice. An important condition is the modelling of basic structural elements and some procedural features of a school lesson while organising university foreign language classes. Particular attention is paid to the implementation of individualised goal-setting, planning and self-assessment (reflection), demonstration of lexis, grammar and phonetics mastering, of active forms and techniques for organising communicative activities, methodological reflection. At the first stage, university students are also offered some methodological tools (for example, goalsetting maps and maps for academic work planning, etc.), which can be used in teaching foreign languages at school. When organising the educational process, much attention is paid to the awareness of methodological facts, phenomena, patterns. Therefore, a new type of exercises (educational-methodological) has been proposed. In addition to an educational task, these exercises contain a methodological task in form of a short comment, an additional question, etc. At the second stage, there is a transition to the organising of a productive methodologically oriented foreign language activity. Three main methods of methodologically oriented teaching are distinguished: modification of authentic (university) materials for different age groups of schoolchildren, conventional “professional test”, and project educational-methodological activity. In conclusion, the main results of the study are summarised.

This paper focuses on some important choices that have to be made in the design of an environmental regulation system of a recreational activity that is exercised on private property and causes external effect on outsiders. Many types of tourist and recreational uses of private property exhibit these features, such as sport fishing; mountain biking; hiking; motorized and non-motorized boating, road or off-road driving; camping; caravans and mobile-homes parking; etc. Under a licence regulation of snowmobile driving that has been proposed in Sweden, a limited number of zonal licences would be sold at predetermined prices. We develop a ‘classic-style’ regulation model and show that a socially efficient solution can be obtained in a licence system where landowners are allowed to sell licences but not to collect penalty charges.

Resumo: A presente pesquisa explorou as relações entre o desempenho no ENADE 2005, o desempenho no EGRAF e o raciocínio dedutivo de 141 estudantes ingressantes e concluintes da Ciência da Computação quando envolvidos em atividades que exploraram o pensar matemático. Os instrumentos foram o exame do ENADE, o exame do EGRAF e o teste psicológico GfRLD. Além disso, doze desses sujeitos foram submetidos a uma testagem individual de alguns componentes da habilidade matemática e a representação mental, além das variáveis estudadas para os 141 estudantes. Para a habilidade e a representação foram utilizados cinco problemas da série XIX-B de Krutetskii e uma entrevista semi-estruturada. Durante a aplicação do teste de Krutetskii, os doze estudantes foram solicitados a pensar em voz alta. Foram feitas anotações complementando informações não captadas via gravação de voz e imagem. Os principais resultados mostraram que nove dos doze estudantes foram considerados mais habilidosos e apresentaram uma tendência para representar os problemas de maneira proposicional. Essa representação sempre que usada por estudantes que dominavam os elementos do problema e suas relações levavamnos ao sucesso em suas soluções. Os desempenhos desses estudantes no ENADE não indicaram estar associados ao fato de serem ingressantes ou concluintes, mas relacionados ao desempenho em nível acadêmico. O raciocínio dedutivo diferiu significativamente entre estudantes concluintes e ingressantes e, dentre os bem e mal sucedidos em atividades acadêmicas. De uma maneira geral, os 141 estudantes tenderam a apresentar associação entre os desempenhos do ENADE e os do EGRAF, que avaliam as inteligências fluido-cristalizadas e cristalizadas, respectivamente
Abstract: he present research explored the relations between the performance in ENADE 2005, the performance in EGRAF and the deductive reasoning of 141 Freshman and Senior students of the Computer Science course when involved in tasks that explored the mathematic thinking. The instruments were the ENADE exam, the EGRAF exam and the psychological test GfRLD. In addition, twelve of those students were submitted to an individual test of some mathematical ability components and the mental representation, over there the variables studied for the 141 students. For the ability and the representation five of Krutetskii's serie XIX- B series problems and a semi structurated interview were used. During the application of the Krutetskii's test, the twelve students were invited to think out loud. Notes were made to complement information not captured by the voice and image videotape. The main results showed that nine out of twelve students were considered more skilful and presented a tendency to represent the problems in a propositional way. This representation when used by students that dominated the elements of the problem and its relations took them to success in their solutions. Those students' performances in ENADE indicated no association with the fact that they were Freshmen or Senior students, but they were related with the level academic performance. The deductive reasoning differed significantly between Freshmen and Senior students and, between well and bad succeeded in academic tasks. In general, the 141 students tended to present association between ENADE performance and EGRAF performance, that evaluate the fluid-crystallized and crystallized intelligences, respectively

Resumo: Esta pesquisa teve como objetivo analisar a importância de se trabalhar uma fase intermediária, que estaria entre a escrita e a reescrita, de um texto narrativo. A partir de um texto narrativo produzido por meus alunos de uma 6ª série de um colégio da rede particular de ensino, elaborei seis exercícios que envolviam recursos lingüísticos que fazem parte do conteúdo programático desta série, que neste trabalho são chamados de exercícios de análise lingüística, apliquei esses exercícios em momentos distintos das aulas de Língua Portuguesa e observei de que maneira eles fizeram uso dos recursos lingüísticos nas duas vezes em que reescreveram o texto narrativo produzido individualmente por eles. É importante ressaltar que as reescritas não foram corrigidas em nenhum momento por mim. que, além de pesquisadora, era professora da turma. De trinta textos escritos e reescritos, oito foram selecionados para a análise. Foram analisadas a primeira e a última versão do texto narrativo. Foi possível observar que os alunos não só modificaram seus textos considerando os exercícios de análise lingüística como também fizeram alterações de ordem gramatical nas reescritas
Abstract: This research aimed to analyze the importance of working an intermediate phase, which would be between the writing and rewriting in a narrative text. Starting from a text produced by my 6th grade students , from a private school I prepared six exercises that involved linguistic resources that are part of the programmatic content of this grade, which is called in this work, exercises of linguistic analysis. I assigned these exercises in different moments of the Portuguese classes , and I observed how they used the linguistic resources on the two moments they rewrote the narrative text , individually produced by themselves. It's important to emphasize that the rewritings were not corrected at any moment by myself , who besides being a researcher , was also their class teacher. Eight out of the thirty rewritten texts were selected for analyses. It was analyzed the first and last version of the narrative text. It was possible to notice that the students not only changed their texts , considering the exercises of linguistic analysis , but also the grammatical order in the rewriting

Texto completoResumen
Alguns instrumentos avaliativos, aplicados aos alunos brasileiros do ensino fundamental (EF), têm mostrado que eles apresentam um fraco desempenho na resolução de situações -problemas de matemática. Segundo os indicadores, os alunos têm concluído a 48 série do Ensino Fundamental (EF) com sérias deficiências em relação aos conteúdos específicos de Matemática. Quando procuramos justificativas para as lacunas existentes na apreensão dos conteúdos da Matemática, existe uma tendência a atribuir grande parte do fracasso dos alunos às metodologias baseadas em técnicas e métodos tradicionais. Visando a mudar o quadro, reformas curriculares apontam para uma abordagem baseada na exposição do aluno a situações-problemas, estimulando o
discente a propor soluções com base nas relações existentes entre o conhecimento matemático, o conteúdo correntemente apresentado e situações concretas do dia-a-dia. Contudo, resultados de avaliações de desempenho de alunos no que diz respeito à Matemática têm revelado que o aluno pode demonstrar dificuldades para compreender as situações-problemas a ele apresentados, o que indica que as dificuldades podem não se limitar simplesmente à falta de conhecimento matemático. O presente Trabalho teve como objetivo investigar se a competência leitora dos alunos interfere na compreensão dos enunciados dos problemas de Matemática. Para o desenvolvimento da Pesquisa, utilizamos, além dos princípios metodológicos de resolução de situações-problemas, considerações teóricas sobre a leitura, acrescidas às contribuições da Lingüística Textual. Para alcançarmos os objetivos do Trabalho, realizamos uma investigação em uma turma de quarta série do EF numa escola municipal de Jaboatão dos Guararapes- PE. Quanto à metodologia, foram realizadas duas atividades para avaliar a compreensão leitora dos alunos e outra para verificar as dificuldades desses alunos quanto à resolução dos problemas matemáticos. Também foi empregado o Teste de Cloze, cujo resultado foi utilizado para agrupar os alunos. Os grupos foram então caracterizados com relação entre a compreensão leitora e à resolução dos problemas matemáticos para avaliarmos a relação entre a compreensão leitora e a resolução dos problemas. A partir da análise das habilidades de cada grupo, pôde-se observar que o baixo desempenho apresentado na resolução dos problemas não está ligado apenas a limitações de cunho eminentemente matemático, mas há uma relação com a baixa competência em leitura observadaSome estimatory instruments, applied to Brasilian basic teaching (BS) students, have shown up displayed that they present a weak performance in mathematics situations problems solution. According to indicators, the students have concluded their BS fourth series, with serious deficiencies regarding to mathematics specifical contents. As we search justifications for these existing gaps in these contents apprehension, understanding, there is a propensity to ascribe most of these failures to methodologies based on traditional know-hows techiniques and methods. Aiming at changing this frame situation, some school curricula reformulations improvements point out to an approaching founded, based on the student exposure to situations-problems, stimulating, encouraging the student, the learning people proposing solutions based on existing rapports between mathematical knowledge, the currently presented content and day by day concrete situations. However, his/her performance evaluations results on Mathematics have revealed displayed that the student con show out manifest some difficulties to understand the situations-problems presented to him/her, which denotes that his/her difficulties can go beyond the mathematical knowledge absence dack. This work aimed at researching whether the students reading skill competency interferes in the mathematics problems enuntiates comprehension. For this research performance, we have used employed beyond the situations-problems solution methodological principles, theoretical considerations regarding to reading, enlarged added- by the textual linguistics contributions. In order to achieve attain this work aims, we have fulfilled an investigation in a BS fourth Series shift, belonging to Jaboatão dos Guararapes/PE `S teaching municipal network. Regarding to the methodology, we have accomplished two activities in order to evaluate the students reading comprehension and another one in order to verify these difficulties as for the mathematical problems solution. We have also employed Clozes Test of which result was used in order to put together the students of the groups were then characterized as for the reading comprehension and mathematical problems solution. From each group habilities, skills analysis, we were able observing that the low performance, presented in the problems solution is connected only with straightly mathematical nature limitations, but there is a strict relation with low skill, competency in observed reading

The purpose of this study is to investigate various solution strategies employed by Grade 7 learners and their teachers when solving a given set of mathematical tasks. This study is oriented in an interpretive paradigm and is characterised by qualitative methods. The research, set in nine schools in the Eastern Cape, was carried out with nine learners and their mathematics teachers and was designed around two phases. The research tools consisted of a set of 12 tasks that were modelled after the Third International Mathematics and Science Study (TIMSS), and a process of clinical interviews that interrogated the solution strategies that were used in solving the 12 tasks. Aspects of grounded theory were used in the analysis of the data. The study reveals that in most tasks, learners relied heavily on procedural understanding at the expense of conceptual understanding. It also emphasises that the solution strategies adopted by learners, particularly whole number operations, were consistent with those strategies used by their teachers. Both learners and teachers favoured using the traditional, standard algorithm strategies and appeared to have learned these algorithms in isolation from concepts, failing to relate them to understanding. Another important finding was that there was evidence to suggest that some learners and teachers did employ their own constructed solution strategies. They were able to make sense of the problems and to 'mathematize' effectively and reason mathematically. An interesting outcome of the study shows that participants were more proficient in solving word problems than mathematical computations. This is in contrast to existing research on word problems, where it is shown that teachers find them difficult to teach and learners find them difficult to understand. The findings of this study also highlight issues for mathematics teachers to consider when dealing with computations and word problems involving number sense and other problem solving type problems.

Thesis (MTech(Education))--Cape Technikon, 1998This study presents a model for the evaluation of educational innovation in a context of transformation. The model incorporates formative, summative and illuminative evaluation goals and emphasises the need to locate the innovation which is being evaluated within the context and policy framework of its operation. The evaluation framework provided by the model takes into account the full range of variables impacting on innovative educational practice and subjects the innovation, along with its transforming educational context, to the scrutiny of evaluation. The ten-stage generalised evaluation model is presented as a framework for the evaluation of any type of educational innovation. In this study the model is applied to the evaluation of an innovative intervention, LEAP (Learning in English for Academic Purposes), at a tertiary institution in South Africa. The LEAP course aims to develop English academic literacy skills in students, foster student-centred learning and teaching and promote the transfer of academic literacy skills across the curriculum. The background to, theoretical underpinnings and development of the course are expanded on in the study. In line with the model, the LEAP intervention is located within the context and policy framework of its academic context. The principal stakeholders in the LEAP intervention are identified. They are used as sources to identify the aspects of LEAP to be evaluated, as well as to identify the criteria for evaluation. An eclectic approach is adopted in the evaluation of the LEAP course. Both quantitative and qualitative data collection methods are employed, using a variety of instruments. A range of sources is consulted to cross-validate the analysis of the data, and recommendations are made on the basis of conclusions drawn from the interpretation of the data. The final section of the study reflects on the whole evaluation process and areas for further research are also discussed.

Resumo: Tornar o ensino dos conteúdos de matemática significativo para os alunos do Ensino Médio é um dos desafios que os atuais professores brasileiros tem enfrentado durante suas aulas. Diante disso, considerando que a matemática é uma ciência de observação e abstração e que as funções reais fazem parte do currículo de matemática do 1º ano do Ensino Médio, propomos como metodologia de ensino a abordagem das principais funções reais ¿ afim, quadrática, exponencial, logarítmica ¿ e suas respectivas representações gráficas a partir de situações-problema do cotidiano. Posteriormente a identificação de qual expressão se adequa à situação, discutimos as principais características dessa função e como elas se relacionam com o cotidiano descrito. Além disso, apresentamos alguns exercícios inéditos e de processos de seleção universitária, que tanto exemplificam qual tipo de questão pode ser usada como avaliação, como demonstram o alinhamento deste método com o Exame Nacional do Ensino Médio (Enem), principal avaliação do governo federal deste segmento da educação básica. Por fim, discutimos uma importante função real presente nas ciências biológicas, a equação logística. Após relembrar historicamente como ocorreu sua conceituação aplicamos a metodologia proposta apresentando a expressão a partir de situações-problema. Feito isto, analisamos as possíveis variações gráficas e o que cada um significa do ponto de vista prático
Abstract: Make the teaching of significant Mathematical content for High School students is one of the challenges that the current Brazilian teachers have faced during their classes. Therefore, considering that Mathematics is a science of observation and abstraction and the real functions are part of the Mathematics curriculum of the 1st year of High School, we propose as a teaching methodology addressing the major real functions - linear, quadratic, exponential, logarithmic - and their graphical representations from everyday problem situations. Later determining which expression suits the situation, we discuss the main features of this function and how they relate to the described daily. In addition, we present some exercises, unpublished and university selection processes that both exemplify the kind of question can be used as evaluation, as demonstrated alignment of this method with the National Secondary Education Examination (Enem), the main assessment of the federal government this segment of basic education. Finally, we discuss an important real function present in the Biological Sciences, the logistic equation. After recall occurred historically as its conceptualization apply the proposed methodology showing the expression from problem situations. This done, we analyze the possible graphical variations and what each means from a practical point of view

This thesis is concerned principally with tangential geometry and the applications of these concepts to tangentially symplectic foliations. The subject of tangential geometry is still at an elementary stage. The author here systematises current concepts and results and extends them, leading to the definition of vertical connections and vertical G-structures. Tangentially symplectic foliations are then characterised in terms of vertical symplectic forms. Some significant particular cases are discussed.

Texto completoResumen
Most of the student’s educational exposure is to well behaved, deterministic problems with known results. Most courses expose students to material in compartmentized modules (chapters of a book) with exercises/problems (at the end of the chapter) where the majority of the material is readily found in the compartmentized module. Unfortunately, real world problems never fit this simple mold. Laboratory is the perfect place for students to become exposed to real world problems and solutions to those problems. Laboratory is the perfect place to put all the student’s knowledge of basic STEM material to the test. However, many times the real world measurement is much more complicated than the textbook problems and students often struggle with methods and procedures to solve a given problem (with no answer at the back of the book). This is true for a mechanical measurement of a simple second order mass, spring, dashpot system which is measured with displacement and acceleration instruments in an existing mechanical engineering laboratory exercise. The measurement is plagued with measurement errors, drift, bias, digital data acquisition amplitude/quantization errors, etc. In order to understand the basic underlying measurement and associated “problems” with the measurement, a simple simulation model was developed. The simulation model allows the students to define a basic second order system and then add different types of “problems” (drift, bias, quantization, noise, etc) to the measurement to see their effects. The simulation module further allows the student to “cleanse” the distorted data using common measurement tools such as coupling, filtering, smoothing, etc. to understand the effects of processing the data. The simulation model is built using Simulink/MATLAB and allows a simple GUI to modify the model, the “problems” added to the data and the “cleansing” of the data, to obtain a better understanding of the problem and tools to process the data. The simulation model is presented and discussed in the paper. Several data sets are presented to illustrate the simulation module.

The paper presents a continuation of the research on the problem of realization of compensation for damage caused by the commission of criminal offense. In the first paper created within the same project, the author laid the foundations of the problem, dealing with the theoretical notion of damage caused by a criminal offense, the notion of civil torts and tortious liability, and the distinction between the notion of damage and the consequence of a criminal offence. This time, the author will concentrate on settling the receivables for damages by presenting the entire path that one claim for damages should take. Namely, obtaining a property claim should occur primarily in criminal proceedings, but it is most often adjudicated in litigation because in most cases the subject entitled to it is referred to litigation in order to exercise his right to compensation. After the judgement in the civil procedure is rendered, which orders the defendant-convict in the criminal procedure to compensate the caused damage either by compensating the damage in money or by returning the thing, or by annulling a certain legal deal, the concrete execution of the verdict in the executive procedure begins. While studying the manner of collecting the claims of the entitled subject through all three different procedures for the damage caused by the commission of criminal offense, the author also deals with controversial issues that may arise (the issue of statute of limitations for property claim, the issue of subjects who may be holders of property claims, the adequacy of the procedure in which the property claim is exercised, the means of execution of a monetary claim for damages caused by the commission of criminal offense, etc.).

Abstract Design fixation has been extensively studied in the context of engineering design, leading to several interventions to reduce its negative effects. The concept of mental fixation has roots in diverse psychological contexts from Freudian psychoanalysis to Gestaltism and eating disorders. Although the underlying concepts are similar, the phenomenon has different names, including mental set, rumination, functional fixedness, obsession, etc. Mental fixation in its various forms is always a barrier to problem solving, whether the problem is a psychological disorder or an engineering-design task. The present paper explores the applicability to design fixation of cognitive therapy, a form of psychotherapy that relies on questioning to identify and modify inaccurate perceptions. Originally developed to treat depression, it is now used to treat a variety of psychiatric disorders. Specific interventions used in cognitive therapy are described in detail towards developing new means of overcoming design fixation. These interventions include cognitive restructuring and exposure response prevention. Also explored are links to other research results from psychology and cognitive science, including focused distraction, and the effects of music and physical exercise. In addition to developing new interventions, existing design-fixation interventions can also be supplemented using insights from these research results.

Design Structure Matrices (DSMs) are a widely spread and useful tool for structuring and analysing design processes and related aspects such as products themselves, organisations, etc. Though this tool is simple, yet quite powerful, problems might arise in using them due to the subjectivity of the set up model within the DSM, as it is with every model building exercise. This contribution looks at the individual differences in filling out a DSM, the reasons for those differences, as well as means to overcome them. This covers a clear procedure for using DSMs, extended tools using and supporting DSMs, and a better understanding of this matrix approach. The latter covers different issues and “linkage types” that can be addressed by a DSM and its use in a system theory context. It also emphasises that DSMs are just one method using a matrix approach, which is only one representation of a graph or a network, with other methods using similar approaches and covering other useful aspects. A simple, yet important contribution of our research is the appropriate direction of DSMs, i.e. the dependencies going from rows to columns or vice versa, since this is an often discussed subject concerning DSMs.

Texto completoResumen
Owing to the persistent interest in the approximate methods, the order of magnitude analysis is revisited in the present work and a method is proposed for the quick estimation of drop in temperature of a fluid flowing through a circular duct. The principle involves judicious guessing of temperature drop for one of the investigated cases, while the temperature estimates for rest of the cases are deduced from the initial guess. A problem of duct flow with widely varying inlet temperature and mass flow rate conditions, typical of a high altitude simulation ground test facilities for scramjet combustors, re-entry vehicles, etc., are considered which vary from 400 K to 1200 K with corresponding mass flow rates of 300 kg/s to 0.5 kg/s. The results of this quick estimation method portray remarkable agreement with the exit temperatures of the fluid as predicted by solving the problem using transient quasi-one dimensional codes and two dimensional CFD techniques over the entire operating regime and hence provide a conservative estimate of vital parameters for any design exercise as well as to rate an existing system at off-design conditions. The significant advantages of the proposed method over the others are viz. (a) simplicity (b) lesser computational effort and (c) reasonable accuracy, will be elucidated in detail in this article.

Increasing compressor pressure ratios (thereby gaining a benefit in cycle efficiency), or reducing the number of stages (to reduce weight, cost, etc.), will require an increase in pressure rise per stage. One method of increasing the pressure rise per stage is by increasing the stage-loading coefficient and it is this topic which forms the focus of the present paper. In the past, a great deal of effort has been expended in trying to design highly loaded blade rows. Most of this work has focused on optimizing a particular design rather than looking at the fundamental problems associated with high loading. This paper looks at the flow physics behind the problem, makes proposals for a new design strategy and explains sources of additional loss specific to highly loaded designs. Detailed experimental measurements of three highly loaded stages (Δh0/U2 ≈ 0.65) have been used to validate a CFD code. The calibrated CFD has then been used to show that as the stage loading is increased the flow in the stator passages breaks down first. This happens via a large corner separation which significantly impairs the stage efficiency. The stator can be relieved by increasing stage reaction, thus shifting the burden to the rotor. Fortunately, the CFD calculations show that the rotor is generally more tolerant of high loading than the stator. Thus, when stage loading is increased, it is necessary to increase the reaction to achieve the optimum efficiency. However, the design exercise using the calibrated CFD also shows that the stage efficiency is inevitably reduced as the stage loading is increased (in agreement with the experimental results). In the second part of the paper, the role profile loss plays in the reduction in efficiency at high stage loading is considered. A simple generic velocity distribution is developed from first principles to demonstrate the hitherto neglected importance of the pressure surface losses in highly loaded compressors.

In this short paper the author tries to explain how a learner-centered student course portfolio has helped him to document the educational outcomes. The author has taught and is currently teaching the subject matter of Hydraulics, Hydrology and Fluid Mechanics at an undergraduate level. Here the author tries to correlate the assessment of student learning to the assessment of instructor teaching methodologies. It is well known that industry is in need of employees that are committed to long-term development and continuous improvement. The key element here is to recognize the fundamental concept that teaching and learning are connected and therefore it is essential that the interaction between the instructor and learner is properly documented in the portfolio. (Cerbin, 1994). While addressing these issues, the author raises five questions: 1. What should be counted as appropriate goals in an undergraduate engineering course that has a significant laboratory component? 2. Are the teaching practices utilized by the instructor in this course providing reasonably acceptable paths toward accomplishing the specified learning goals? 3. What do students actually accomplish in the course and the laboratory exercises and how does the instructor’s teaching methodologies contribute to students’ intellectual development and progress? 4. How does the instructor respond to students’ learning difficulties? Does the teacher revise the teaching strategies to address such problems? 5. What impact does this type of teaching have on students’ life-long learning attitudes? Are they able to “learn, how to learn.” A course portfolio is deemed as a specified document that represents the specific accomplishments of the student and is structured to explain what, how and why the students learnt in that particular course. The portfolio shall include everything that was accomplished in that particular course. It should contain a teaching statement that provides a flow-chart. (Knapper, 1995). Further, an assessment analysis of student learning should be supported by class work, problem sets, quizzes, examinations, research reports, term papers, examinations, laboratory reports, etc. An analysis of student feedback is essential to document teaching effectiveness. Finally, a comprehensive course summary. The summary should describe the strengths and weaknesses of the course in terms of students’ learning. (Richlin, 1995).

The FPSOs are a type of offshore platforms that are directional in nature. Since a large ship (presently the use of a VLCC - Very Large Crude Carrier - is very common) is used, there is a great importance the direction the waves hit the hull. Differently from a real ship, the FPSO cannot resort to maneuvering to avoid waves. It has been found that there is a possibility, in certain cases, that a rolling resonant wave may reach some stationary FPSOs and consequently, a very high response may be obtained. Sometimes, it is not possible to use large bilge keel and the alternative is to consider the use of other devices such as stabilizing tanks and U-tubes. Faced with this problem, the present work performed model tests in a deepwater ocean basin showing the effectiveness of the stabilizing tank. On the other hand, it is clear that due to the presence of mass, restoring motion and damping that the design problem may be tackled by the use of classical dynamic absorber theory. For this reason, a simplified problem was formulated by replacing the stabilizing tank by a passive concentrated mass on board. The fully nine dimensional and non-linear model are then recovered. Six degrees of freedom are to describe the ship motion and the renaming three are for the mass on board. Based on these preliminary studies, the work describes the use of tests with reduced models showing the usefulness of the theory in practice. The test results together with 2 and 4 degrees of freedom system addresses the importance of the roll-sway coupling. Subsequently, a careful linearization is made for the purpose of identifying the commanding variables such as the mass, the position above the keel, the damping, the dynamic absorber natural frequencies, etc. After that, several parametric studies have been performed, identifying the range of applicability of the variables. Finally, this theoretical-experimental exercise addresses back the use of the applicability of the stabilizing tank.

Conventional learning guidance systems are typically automated machines for creating teaching materials: quizzes, exercises, examinations etc. In the future, systems will also offer ease of use, attention to sociality, ability to adapt to the pupil's needs and skill levels, and time savings. Ease-of-use and adaptation can be sought using systems based on Artificial Intelligence (AI). Chatbots would save teachers time by talking with students about their problems automatically. The virtual classroom would release people from the physical state and offer the opportunity to play with different roles. For the teaching of physics, the virtual classroom provides an opportunity to try out things that are not practically possible. AI could enable automatically identify students’ strengths and weaknesses and utilize them. On the other hand, AI also could allow pupils to gain strength through peer learning by bringing students of the same level from all over the world to discuss their own views and could automatically filter out sub-standard and clearly false answers. AI can also be capable of automatically creating tailor-made materials based on student-level learning using deep learning. Finally, AI can also be used to treat pupils' reviews to a large extent. In this research we will evaluate how well new technology powered by AI could respond to the demands of different teaching-learning environments. We will present a learning system that is in use and discuss its differences between opportunities of Artificial Intelligence (AI) can support different teaching-learning environments and discuss little how AI could support different learning styles. Keywords: automatic teaching machine, artificial intelligence, student centric learning, learning environment, learning style.

"Integrated Gas Source Analysis for Wells with Sustained Casing Pressure: A Case Study from Sour Gas Fields in Sichuan Basin, China". En International Petroleum Technology Conference. IPTC, 2021. http://dx.doi.org/10.2523/iptc-21485-ms.
Texto completoResumen
Abstract Sustained casing pressures are observed in many gas-field wells in Sichuan Basin. The presence of corrosive sour gas i.e. H2S and/or CO2 in the annulus, coupling with the none corrosion-resistant alloy (CRA) casing materials, may damage the casing and lead to loss of containment, which could be a disaster to the asset, local communities, and the environment. It is thus of significance to identify the gas source for the wells with sustainable casing pressure. Several wells in the study area were identified as risky wells with an initial risk screening exercise. The further determination of gas source, either sweet gas in the shallow formation or sour gas in the deep formation, would have a big impact on the risk levels and subsequent mitigation plans. An integrated forensic study was conducted to investigate the gas source, including annulus gas composition analysis, isotope fingerprinting, casing pressure profile construction and analysis, casing pressure bleed-off and build-up operations, cement quality evaluation, temperature and noise logging analysis, etc. In this paper, the integration of various tools and data enabled a quality diagnosis of the gas source for two risky wells. It is believed the most likely gas source for the first well is from the shallow sweet gas formation. The risk was then revised down to Low-Medium, and the well was temporarily plugged and abandoned (P&A) for future use. For the second well, the gas source is confirmed from the deep sour gas formation, and thus the risk is relatively high. A permanent P&A program was performed, and both the sour and sweet gas layers were successfully isolated per the standard barrier requirement to protect community and environment. In conclusion, most of the subsurface measurements have limitations and thus result in the imperfect data. The key to solving the subsurface puzzle is to consolidate all the perceptions together after reviewing the problem from different angles. The integration of multiple types of data in this study, including geological and engineering data, static and dynamic measurements, etc., allows a mostly likely interpretation of gas source to support the key operations decision. The results from integrated data analysis have helped improve the risk assessment, guide the development of risk mitigation plans and operations procedures to eliminate and/or reduce the risk of these wells and secure the subsurface integrity.
