Full textAbstract:
Recent literature in second language acquisition shows that syntax-driven structures give way to successful modal interpretation and morphological production, while discourse-dependent environments do not (Sorace, 2005; Tsimpli & Sorace, 2006, Borganovo, Bruhn de Garavito, & Prévost, 2008; Iverson, Kempchinsky, & Rothman, 2008). It has also been suggested that discourse-dependent environments involve both structural and pragmatic knowledge of L2, which intersect at the syntax-discourse interface (Sorace, 2005; Iverson, Kempchinsky, & Rothman, 2008), thereby requiring a multi-layered understanding of the target language. The present study contributes to this line of research by further examining morphological variability (Prévost & White, 2000; Sorace, 2000; Sorace, 2005; Iverson, Kempchinsky, & Rothman, 2008; Slabakova, 2009) in L2 acquisition at the morphosyntactic-semantic interface, following the work of Borganovo, Bruhn de Garavito, & Prévost (2008). The results of our study reveal that learners, even at advanced stages of acquisition, perform poorly in epistemic environments where syntax and discourse intersect. In such environments, there appears to be an interaction with pragmatics (cf. Iverson, Kempchinsky, & Rothman, 2008) that causes learners to opt for the indicative mood, even when the subjunctive is prescriptively required. Unlike deontic modality, which is essentially syntax-driven, epistemic modality requires structural knowledge, as well as knowledge from other domains (Sorace, 2005). Our study reveals that learners at all levels of instruction performed better in “purely syntactic” environments of deontic modality than in pragmatically challenging epistemic environments.

Full textAbstract:
A set of relationships between parameters of the Dunham and Murrell-Sorbie potential energy function is developed. By employing Taylor series expansion and comparison of terms arranged in increasing order of bond length, a set of Dunham coefficients is obtained as functions of Murrell- Sorbie parameters. The conversion functions reveal the importance of factorials in extracting Dunham coefficients from Murrell-Sorbie parameters. Plots of both functions, based on parameters of the latter, reveal good correlation near the equilibrium bond length for a group of diatomic molecules. Potential function relations, such as that shown in this paper, are useful when the preferred/reliable data is based on a potential function different from that adopted in available computational software.

Extensive exposure of zinc(II) ions may cause eminent health problems, such as stomach cramps, skin irritations, vomiting, anaemia, a damage of pancreas, the disturbance of protein metabolism, and also respiratory disorders. Due to these problems, zinc(II) concentration in drinking water should be controlled. Peat is one of the material that can be used to minimize zinc(II) ions from a solution. The study was done to determine the performance and sorption equilibrium of zinc ions onto oligothropic peat particles. The sorption experiments were conducted in a several batch reactor of erlenmeyer flask at a constant temperature of 26 ± 3 oC. The initial zinc ions concentration and pH were varied. Response variable was residual zinc concentration that was measured spectrophotometrically. Experimental data show that the optimum sorption efficiency was about 90% for the initial zinc(II) concentration of 50 mg/L. Sorption equilibrium can be represented by the Freundlich and Langmuir isotherm models. For the initial pH of 6, the optimum sorption capacity, qo was 3,736 mg/g, and the Freundlich’s characteristic constant, Kf was about 0,342 L/g. Key words : peat, sorption equilibrium, sorption isotherm, zinc(II) ions AbstrakPaparan ion seng(II) pada kadar tertentu dapat menyebabkan berbagai masalah kesehatan seperti kram perut, iritasi kulit, batuk, anemia, kerusakan pankreas, gangguan metabolisme protein, penyumbatan pembuluh darah, hingga kerusakan sistem pernafasan. Karena itu, seng(II) termasuk kategori unsur yang harus dibatasi konsentrasinya dalam air minum. Gambut adalah salah satu material yang dapat digunakan untuk mengurangi ion seng dari larutan. Penelitian ini bertujuan untuk mempelajari performansi dan kesetimbangan sorpsi ion seng(II) pada partikel gambut oligotropik Indonesia. Penelitian dilakukan secara batch di dalam sejumlah labu erlenmeyer pada temperatur konstan 26 ± 3 oC. Eksperimen dilakukan dalam beberapa variasi konsentrasi awal ion seng dan pH. Data primer adalah konsentrasi residual seng dalam larutan yang diukur secara spektrofotometrik. Hasil penelitian menunjukkan bahwa efisiensi optimum sorpsi mencapai lebih dari 90% untuk konsentrasi awal seng 50 mg/L. Kesetimbangan sorpsi logam seng(II) pada partikel gambut dapat direpresentasikan dengan baik oleh model isoterm Freundlich dan Langmuir. Untuk rentang pH awal 6, nilai kapasitas sorpsi optimum, qo adalah 3,736 mg/g, sedangkan nilai konstanta karakteristik Freundlich, Kf adalah 0,342 L/g.

The application of spatiotemporal (ST) analytics to integrated data from major sources such as the World Bank, United Nations, and dozens of others holds tremendous potential for shedding new light on the evolution of cultural, health, economic, and geopolitical landscapes on a global level. Realizing this potential first requires an ST data model that addresses challenges in properly merging data from multiple authors, with evolving ontological perspectives, semantical differences, and changing attributes, as well as content that is textual, numeric, categorical, and hierarchical. Equally challenging is the development of analytical and visualization approaches that provide a serious exploration of this integrated data while remaining accessible to practitioners with varied backgrounds. The WSTAMP project at Oak Ridge National Laboratory has yielded two major results in addressing these challenges: 1) development of the WSTAMP database, a significant advance in ST data modeling that integrates 10,000+ attributes covering over 200 nation states spanning over 50 years from over 30 major sources and 2) a novel online ST exploratory and analysis tool providing an array of modern statistical and visualization techniques for analyzing these data temporally, spatially, and spatiotemporally under a standard analytic workflow. We discuss the status of this work and report on major findings.

AbstractSome key physical processes that impact the evolution of Earth's atmosphere on time-scale from days to millennia, such as the EUV emissions, are determined by the solar magnetic field. However, observations of the solar spectral irradiance are restricted to the last few solar cycles and are subject to large uncertainties. We present a physics-based model to reconstruct short-term solar spectral irradiance (SSI) variability. The coronal magnetic field is estimated to employ the Potential Field Source Surface extrapolation (PFSS) based on observational synoptic charts and magnetic flux transport model. The emission is estimated to employ the CHIANTI atomic database 8.0. The performance of the model is compared to the emission observed by TIMED/SORCE.

Abstract. Although exit polling has not been used to study Canadian elections before, such polls have methodological features that make them a potentially useful complement to data collected through more conventional designs. This paper reports on an experiment with exit polling in one constituency in the 2003 Ontario provincial election. Using student volunteers, a research team at Wilfrid Laurier University conducted an exit poll in the bellwether constituency of Kitchener Centre to assess the feasibility of mounting this kind of study on a broader scale. The experiment was successful in a number of respects. It produced a sample of 653 voters that broadly reflected the partisan character of the constituency, and which can hence be used to shed light on patterns of vote-switching and voter motivations in that constituency. It also yielded insights about best practices in mounting an exit poll in the Ontario context, as well as about the potential for using wireless communication devices to transmit respondent data from the field. The researchers conclude that exit polling on a limited basis (selected constituencies) is feasible, but the costs and logistics associated with this methodology make a province-wide or country-wide study unsupportable at present.Résumé. Bien que les sondages “sortie des urnes” n'aient pas été utilisés jusqu'ici dans l'étude des élections au Canada, de tels sondages possèdent certaines caractéristiques qui en font un complément potentiellement très utile des méthodes plus traditionnelles de cueillette des données. Cet article rend compte d'un sondage “sortie des urnes” expérimental effectué dans une circonscription lors de l'élection provinciale de 2003 en Ontario. Utilisant des bénévoles étudiants, une équipe de recherche de l'Université Wilfrid Laurier a conduit un sondage “sortie des urnes” à Kitchener Centre, une circonscription indicatrice de tendance, afin de déterminer la faisabilité de ce type d'étude au niveau fédéral. L'expérience a réussi à plusieurs égards. Elle a fourni un échantillon de 653 électeurs qui reflétaient en gros le caractère partisan de la circonscription, ce qui a rendu possible l'étude des motivations des électeurs et des revirements de vote dans la région. L'expérience a aussi fourni des renseignements sur les pratiques exemplaires concernant l'utilisation des sondages “sortie des urnes” au niveau provincial, ainsi que sur la possibilité d'employer des techniques de communication sans fil pour transmettre les données recueillies des répondants. Les chercheurs ont conclu que les sondages “sortie des urnes” sont réalisables dans un cadre restreint, dans certaines circonscriptions sélectionnées, mais que les coûts et la logistique nécessités par cette méthodologie la rendent actuellement impraticable pour une étude à l'échelle provinciale ou nationale.

Full textAbstract:
Pepper (Capsicum annuum) is one of the major vegetable species in the world, and Serbia as well. The pepper assortment of the Institute of Field and Vegetable Crops includes varieties of different fruit type such as the bell, conical, kapia, elongated, pepperoni and tomato-shaped peppers. However, in the assortment of the Institute, there is no variety of sweet pepper with conical and hanging fruits. Because of that, we wanted to develop a new pepper variety with this fruit type and offer it to the market. Selected lines from one of the crossbreeding combinations were grown in the open field and the greenhouse area by the pedigree method in the period 2012-2017. Based on the phenotype, the most vital plants that had the desired characteristics of the fruit were selected. During the many years of breeding, a new pepper variety NS Prva was obtained. NS Prva has been registered in the Republic of Serbia in 2019 and from that period it has been on the National variety list. The fruits of this variety are about 150 g, have one peak, grow hanging on the plant, with light yellow colour in technological maturity, and red in full maturity. A new pepper variety NS Prva is recommended for growing in a greenhouse where it gives uniform fruits suitable for the market in all maturity stages. It can also be recommended for growing in the open field where it gives slightly longer fruits. NS Prva showed good storage ability three weeks after harvest since it had the smallest reduction in fruit weight during storage in a cold chamber

Full textAbstract:
In this paper we present an analysis of Spanish heritage speakers’ oral production of gender agreement outside the DP as an innovative source of support for the Interface Hypothesis (Sorace & Filiaci 2006). We demonstrate that, besides commonly known factors such as the gender, animacy and morphology of the antecedent, the interface domain in which gender agreement takes place also seems to play a role in how accurately heritage speakers apply gender agreement. Pronominal reference, located at the external syntax-discourse interface, turns out to be more problematic than adjectival predication, which pertains to the internal morpho-syntax interface. Furthermore, we discuss the possibility that, besides the amount of input heritage speakers receive, the quality of this input may also play a role in their gender agreement accuracy, given that the heritage speakers’ error pattern with respect to linguistic factors is very similar to that of first generation immigrants.

Full textAbstract:
I describe research done in collaboration with J. Sorce showing that one cannot over-charge and/or over-spin an initially slightly nonextremal Kerr–Newman black hole via the type of gedanken experiments proposed by Hubeny and others, assuming that the nonelectromagnetic stress-energy tensor of the matter entering the black hole satisfies the null energy condition. Analysis of such gedanken experiments requires that we calculate all effects on the final mass of the black hole that are second-order in the charge and the angular momentum carried into the black hole. We do so using Lagrangian methods, and our formula for the second-order correction to mass, [Formula: see text], is obtained by generalizing the canonical energy analysis of Hollands and Wald to the Einstein–Maxwell case. Our formula for [Formula: see text] automatically includes all self-force and finite size effects.

In the specified large combustion plant, fuel with a large content of sulfur is burned. The current desulfurisation method is not able to meet the new emission limits, therefore it is necessary to design an adequate desulphurisation method. The theoretical part of this diploma thesis contains a description of the legislation related to emission limits for large combustion plants and an analysis of individual technological methods of desulphurization together with a description of the relevant sorbents. The practical part of the work contains a design of dry conditioned sorption with the using of a calcium-based sorbent. The basic technological and structural design is designed together with the spatial solution and dispositional solution of the whole technology.

Analysis of the regional energy supply, shows that suitable alternative may be a combination of primary energy sources with the municipal solid waste to energy plant. Starting from the fact that the regional thermal energy needs are characterized by smaller power demand, but relatively significant seasonal fluctuations in heat supply. These factors limit the processing performance of the considered waste to energy plant that could be included in the system of regional energy supply. The aim of the thesis was to propose adequate treatment capacity for regional waste to energy plant and explore alternative solutions in off-gas cleaning for exhaust gases generated during incineration of MSW. The balance sheets of two alternative solutions off gas cleaning are part of the thesis, both in terms of material and energy consumption. Presented evaluation of economic demands alternative arrangement of off gas cleaning includes operating costs and the impact on earnings from energy production.

In the face of the overall state of affairs in society, which seems to be characterised by crises, (right-wing) populism, uncertainty and radicalisation, the concept of ‘concern’ appears to be a key idea in modern society. The underlying idea behind the discussion compiled in this book is to investigate concern from the perspective of a carefree attitude. Such an approach might provide us with a clearer understanding of the multifaceted and complex phenomenon of concern. Concern can be regarded as the manifestation of a longing for a carefree life without the burden of tedious tasks or demands that are too high. However, concern can also be understood as something active—being carefree through lovingly caring for someone or behaving responsibly. This study’s approach of incorporating the idea of being carefree into the debate about concern makes the ambiguity of this concept clear: concern both inhibits and incentivises action; it is both restrictive and empowering.

Full textAbstract:
Mevalonate kinase deficiency (MKD) is an autosomal recessive inborn error of isoprenoid biosynthesis, a pathway yielding sterols and nonsterol isoprenoids.In patients, the enzyme activity of mevalonate kinase is severely reduced due to mutations in the encoding gene, MVK. The substrate, mevalonate, accumulates and is elevated in blood and urine. Shortage of certain downstream products of the pathway, nonsterol isoprenoids, leads to dysregulation of the innate immune system, activation of inflammasomes, and interleukin (IL)-1 mediated inflammation.Symptoms start in early childhood with recurrent attacks of fever, vomiting, diarrhea, headache, sore throat, abdominal pain, arthralgias, painful lymphadenopathy, hepatosplenomegaly, skin rash, and mucosal ulcers. Severely affected patients have additional symptoms, such as intellectual impairment, progressive cerebellar ataxia, and tapetoretinal degeneration. Complications include intestinal obstruction, AA-amyloidosis, hemophagocytosis, and severe infection.Management of MKD is directed at controlling inflammation.

Full textAbstract:
AbstractAtrophic scars may be defined as depressive areas on the skin, due to a defect of fatty tissue under the skin. This situation may lead to adherence to the depth (fascia, bone, tendon) to be a source of functional impairment. Most of the atrophic scars are secondary to acne localized over the face. Multiple techniques were proposed to restore the volume and uniformize the surface, like laser, injection of fat, microneedling, microdermabrasion, dermal fillers, and surgical techniques such as subcision and platlet rich plasma (PRP). On the basis of level 1 evidence currently available, it appears that PRP can improve the quality of atrophic acne scars treated with ablative fractional CO2 laser and decrease the duration of laser-related side effects including edema and erythema (Goutos). Regenerative surgery, including fat harvesting, centrifugation, and isolation of adipocyte stem cells, has been promoted since years and should be repeated when injected fat progressive crush is observed. The clinical case presented here is a paraplegic patient presenting a pressure sore in the left ischiatic area. The flap was successful but the depth of the transplanted fatty tissue was decreasing after some years. A first fat injection was programmed.

Bleeding into the skin may occur for local reasons or as part of a systemic disorder. The distribution of lesions is important: widespread lesions suggest a systemic problem, whereas regional lesions suggest that local factors predominate. Widespread flat purpura without erythema should prompt a search for underlying haematological abnormalities such as platelet disorders. In patients with acute peripheral ischaemia, it is important to exclude embolism. A pressure ulcer (decubitus ulcer, bedsore, pressure sore) is due to localized injury to the skin and/or underlying tissue as a result of pressure alone, or in combination with shear and/or friction. Meanwhile, acute deep venous thrombosis may be silent but usually results in skin erythema and limb oedema. Consequences of post-thrombotic vein damage include further deep venous thrombosis, superficial thrombophlebitis, oedema, skin changes, and eventually ulceration.

Severe Acute Respiratory Syndrome Virus 2 (SARS-CoV-2) is the causative agent of coronavirus disease 2019 (COVID-19), which was identified at the end of December 2019 in China. Symptoms of COVID-19 can appear after an incubation phase of the virus of 2 to 14 days, the most common being fever, cough, and asthenia. Other specific symptoms may include shortness of breath or difficulty breathing, muscle pain, sore throat, chills, loss of smell or sensation, chest pain, headache, nausea, rash, diarrhea, and vomiting. The severity of these symptoms can be mild or even extreme causing serious damage to several organs, directly and indirectly, namely pulmonary, renal, hepatic, cardiac, digestive, neurological. Some people have only mild symptoms, while others are asymptomatic. Seniors or those at risk for certain chronic diseases, such as massive obesity, diabetes, heart disease, lung disease, kidney disease, immune system abnormalities, and liver disease are more susceptible to COVID-19 and can develop more serious and fatal complications.

Before learning about the symptoms of psychosis, it is important to understand what doctors mean by the words symptoms, signs, syndromes, and diagnosis. In this chapter, we explain these four words and then describe the various symptoms of early psychosis. Nearly any illness, whether it affects the body or the brain, causes symptoms. A symptom is an obvious change from one’s normal health that happens when an illness or disease occurs. For example, symptoms of a heart attack may include chest pain, pressure in the chest, pain running down the left arm, problems breathing, nausea, and sweating. Symptoms of the fl u may include fever, chills, cough, sore throat, and nausea. Symptoms often are the reason you go to a doctor or other health-care provider. The doctor then examines the patient to look for signs. Signs are like symptoms, but a doctor sees them through an interview, exam, or test, while symptoms are experienced by the patient. The patient may not even know that he or she has signs of an illness. For example, during a routine check-up, the doctor may discover that the patient has high blood pressure or high cholesterol. These signs could mean that the patient has heart disease or is at risk for a heart attack. Most medical diseases and mental illnesses cause both symptoms that patients experience and signs that doctors observe. A combination of both symptoms and signs is a syndrome. A heart attack is an example of a medical syndrome. Another example, diabetes, has symptoms such as being thirsty and frequent urination, and signs such as high levels of glucose, or sugar, in the blood. Some other medical syndromes are an ear infection, the flu, arthritis, and stroke. There also are many types of mental illness syndromes, such as depression, panic attacks, psychosis, and dementia. This book focuses on the syndrome of psychosis. It especially focuses on the first time psychosis appears, usually between the ages of 16 and 30 years. The word diagnosis (plural, diagnoses) refers to the specific medical word(s) given to an illness or syndrome by health-care providers. Examples of medical diagnoses include “diabetes mellitus” (diabetes), “acute myocardial infarction” (heart attack), and “cerebrovascular accident” (stroke).

Fibromyalgia is a syndrome rather than a disease, and as such has a variety of features. Any part of the body can be involved, especially when fibromyalgia is induced or aggravated by multiple factors. This chapter will review some of the generalized complaints expressed by fibromyalgia patients and place them in perspective. One of the major problems fibromyalgia sufferers encounter is difficulty communicating how they really feel. Complaints can be subjective and hard to verify or quantify. They consist of symptoms, or expressions of what is bothersome, and signs. Physical signs are observed during a physical examination, such as a rash or an irregular heartbeat, and are easier to validate. Constitutional symptoms or signs are generalized and do not belong to any specific organ system or region of the body. Jane was an anthropology graduate student. In addition to carrying a full load of classes, she moonlighted as a waitress 20 hours a week. This pace was maintained until Jane caught what seemed to be a bad case of flu with a sore throat, runny nose, cough, fever, aching, fatigue, and swollen glands. Although most of her flu symptoms disappeared after several weeks, Jane never felt the same. The fatigue and aching became more pronounced, and Jane had to quit her waitressing job. She forced herself to go to class and was so exhausted that she spent most weekends in bed. Despite all of the bed rest, Jane never slept well and began noticing stiffness and spasm in her upper back and neck areas. The Student Health Service referred her to an internist, who ordered tests, all of which were normal. Jane now paces herself with rest periods alternating with active ones, avoids daytime sleeping, takes cyclobenzaprine (Flexeril) two hours before retiring at night, and engages in a general conditioning program. Even though Jane is still unable to work, at least she did not have to drop out of school. Fatigue is still a major problem, but its level of intensity seems to be slowly diminishing. As with Jane, generalized fatigue is a prominent feature of fibromyalgia.

Full textAbstract:
Children experience a variety of oral medicine and oral surgical problems, of which some last into adulthood and some resolve with or without intervention by the dentist or doctor. Even where the same pathology is found in both adults and children the approach to management and the issues of delivering dental care may be very different in each group. This chapter reviews conditions of the orofacial region, oral soft tissues, and bone that are frequently found in children or require a particular approach to their management in a paediatric population. The examination of the child starts as soon as the dentist and the child meet. Observations about a child’s weight, height, and development for his/her age, the attachment to the parent or siblings, and even the clothing worn by the child can be important. Apart from being a good starter to a conversation, the child’s new clothes or shoes can suggest a period of growth. Facial and perioral observation is best completed when seeing the child initially, as first impressions of swelling or asymmetry can be investigated later during the standard clinical examination. Although the history will elicit the findings needed to diagnose dental as well as non-dental conditions, the information needed for non-dental conditions and the impact that these conditions have on the child need particular exploration. When at all possible the child should be the source of the information—usually supported by the views of a parent—but it is important to have the child as the focus for initial information gathering. Be careful not to interpret the language used too literally—not every ‘ulcer’ turns out to be such, and always ask ‘What do you mean by …’ if the child or parent uses a word with a particular meaning to the dentist. Many ulcers subsequently turn out to be ‘sore bits’ with questioning—let the child use language with which they are comfortable. Always ask the child for permission before starting an extra- or intraoral examination of the soft tissues and explain what is going to happen.

Full textAbstract:
There is widespread recognition that children with specific learning difficulties may experience social and emotional problems because of their learning difficulties, but it is often not realized that impairment of social skills may itself be a form of learning difficulty. This is due to a limitation in the way that the brain is able to understand social conventions. This is called a social cognition (or social learning) deficit. In this chapter, I shall first discuss social cognition deficit, and then discuss a number of behaviour problems that may occur as a result of a specific learning difficulty. Social skills, like any other skills, have to be learned. Yet much of what children learn about socially appropriate behaviour is not actually taught to them; they simply pick it up as they go along. Some children of normal intelligence seem to be less able to learn these things, even when taught. This may be their only area of difficulty, but it is commonly associated with other learning difficulties. These children have been accurately described as being ‘socially tone deaf’. They do not pick up the same cues as other children of the same age. They do not seem to predict the social consequences of their actions. They may be uninhibited, undressing in public without the same embarrassment that their peers would experience. They may be overfriendly to strangers. They may frequently say very tactless things without realizing the effect they are having. They often do not read facial expressions and are oblivious to whether someone is angry or upset with them. They may kiss classmates at an age where this is no longer appropriate. They may make unusual sounds in public. They may be insatiable in their activities, not knowing when to stop in the way another child of their age would. Although such behaviour may be apparent to all who meet the child, the people who are most likely to notice it are the child’s peers. With them, the child often sticks out like a sore thumb. This is something that may not be apparent if the child is only observed in a one-to-one relationship at a clinic.

Spam, undesired and usually unsolicited e-mail, has been a growing problem for some time. A 2003 Sunbelt Software poll found spam (or junk mail) has surpassed viruses as the number-one unwanted network intrusion (Townsend & Taphouse, 2003). Time magazine reports that for major e-mail providers, 40 to 70% of all incoming mail is deleted at the server (Taylor, 2003), and AOL reports that 80% of its inbound e-mail, 1.5 to 1.9 billion messages a day, is spam the company blocks. Spam is the e-mail consumer’s number-one complaint (Davidson, 2003). Despite Internet service provider (ISP) filtering, up to 30% of in-box messages are spam. While each of us may only take seconds (or minutes) to deal with such mail, over billions of cases the losses are significant. A Ferris Research report estimates spam 2003 costs for U.S. companies at $10 billion (Bekker, 2003). While improved filters send more spam to trash cans, ever more spam is sent, consuming an increasing proportion of network resources. Users shielded behind spam filters may notice little change, but the Internet transmitted-spam percentage has been steadily growing. It was 8% in 2001, grew from 20% to 40% in 6 months over 2002 to 2003, and continues to grow (Weiss, 2003). In May 2003, the amount of spam e-mail exceeded nonspam for the first time, that is, over 50% of transmitted e-mail is now spam (Vaughan-Nichols, 2003). Informal estimates for 2004 are over 60%, with some as high as 80%. In practical terms, an ISP needing one server for customers must buy another just for spam almost no one reads. This cost passes on to users in increased connection fees. Pretransmission filtering could reduce this waste, but creates another problem: spam false positives, that is, valid e-mail filtered as spam. If you accidentally use spam words, like enlarge, your e-mail may be filtered. Currently, receivers can recover false rejects from their spam filter’s quarantine area, but filtering before transmission means the message never arrives at all, so neither sender nor receiver knows there is an error. Imagine if the postal mail system shredded unwanted mail and lost mail in the process. People could lose confidence that the mail will get through. If a communication environment cannot be trusted, confidence in it can collapse. Electronic communication systems sit on the horns of a dilemma. Reducing spam increases delivery failure rate, while guaranteeing delivery increases spam rates. Either way, by social failure of confidence or technical failure of capability, spam threatens the transmission system itself (Weinstein, 2003). As the percentage of transmitted spam increases, both problems increase. If spam were 99% of sent mail, a small false-positive percentage becomes a much higher percentage of valid e-mail that failed. The growing spam problem is recognized ambivalently by IT writers who espouse new Bayesian spam filters but note, “The problem with spam is that it is almost impossible to define” (Vaughan-Nichols, 2003, p. 142), or who advocate legal solutions but say none have worked so far. The technical community seems to be in a state of denial regarding spam. Despite some successes, transmitted spam is increasing. Moral outrage, spam blockers, spamming the spammers, black and white lists, and legal responses have slowed but not stopped it. Spam blockers, by hiding the problem from users, may be making it worse, as a Band-Aid covers but does not cure a systemic sore. Asking for a technical tool to stop spam may be asking the wrong question. If spam is a social problem, it may require a social solution, which in cyberspace means technical support for social requirements (Whitworth & Whitworth, 2004).

Full textAbstract:
Abstract Scroll expanders are generally used for low temperature power generation applications due to their inherently small built-in volume ratio. The working fluid and operating conditions play an important role in the expander performance as well as its physical size and volume ratio. Hence, a comparative study of scroll expander performance was carried out between two different working fluids, R433C and supercritical (s-CO2). The s-CO2 Brayton cycle achieved a maximum cycle efficiency of 13.6% at an expander supply pressure of 11 MPa. Two separate scroll geometries were modeled for supercritical Organic Rankine Cycle (SORC) using R433C and s-CO2 Brayton cycle for the operating conditions that provided the maximum cycle performance. The s-CO2 scroll geometry achieved a maximum expander efficiency of 80% with a volume ratio of 2.5 and a diameter of 19 cm. The high inlet temperatures required a much higher volume ratio of 6.2 and scroll diameter of 30 cm for the R433C based SORC leading to greater leakages and lower expander efficiency of 62%. The comparative study shows that s-CO2 is better suited for scroll expander than R433C at such high expander supply temperatures.

Full textAbstract:
Abstract This paper is dedicated to the selection of the most effective way of mitigating surfactant adsorption in chemical EOR flooding. Mitigation strategies based on either water treatment or adsorption inhibitors were benchmarked for a sea water injection brine, on both performances and economics aspects. Performances in surfactant adsorption reduction were evaluated by applying salinity and/or hardness gradient strategies through dedicated water softening techniques, such as reverse osmosis or nanofiltration. Adsorption inhibitor addition, which does not require any water treatment, was also assessed and optimized for comparison. For each scenario, a suitable surfactant formulation was designed and evaluated through phase diagrams, static adsorption and diphasic coreflood experiments. Then the real benefit of surfactant adsorption reduction on the overall EOR process economics (including the costs of chemicals and water treatment) was assessed depending on the selected strategy. Sea water was considered as the injection brine for this study as it is widely used in chemical EOR process and often suffers high surfactant adsorption level. It was found that residual oil saturation after chemical flooding (SORc) dropped from 29% to 7% by applying a hardness gradient through nanofiltration process while 4% was reached with reverse osmosis. Regarding costs and footprint however, nanofiltration was found to be more advantageous. Adsorption inhibitors addition met similar performances to nanofiltration-based process (SORc=7%) and could be a valuable option depending on injected volume (pilot or small deployment) or field location (off-shore) as they do not require water treatment plant investment. Overall, this study provides useful practical insights on both performances and economics for selecting the most adapted strategy depending on the considered field case.

Full textAbstract:
Aircrew members sit on ejection seats for a long period of time on operational missions. It is paramount for them to be as comfortable as possible within the constraints of this seat system to maximize their operational performance. Several health effects like numbness, pressure sore, low back pain, and vein thrombosis have been associated with protracted sitting. The cushion, and of late the installation rail angle are the only components of the ejection seat system that can be modified to reduce these adverse effects. This comprehensive static comfort assessment for ejection seats provides comparison between a variety of operational and prototype cushions (three in all: baseline cushion, honeycomb and air-cushion) and different installation rail angles (14°, 18°, and 22°) with 18° nominally used as the starting point. Three operational cockpit environment mockups with adjustable rail angle were built. Ten volunteer subjects, six females and 4 males, ages 19 to 35, participated in the comfort assessment. The volunteers fit within the JPATS cases 1–7 range of anthropometry, and each of them tested all cushions in all three installation rail angles. The volunteer clothing was similar the fighter pilot clothing ensemble (including harness). Each comfort assessment test lasted for six-hours, during which the subjects could not leave the seat and movement activities in the seat system were reduced as much as possible to reflect flight conditions. The subjective comfort survey and objective data such as seat pressure, blood pressure, and oxygen blood flow were gathered during the sitting period. The test results indicated that for objective methods, rail angle 22° persistently has a lowest seated pressure, while 18° has the highest pressure. An air-cushion has and maintains the lowest seated pressure, while a honeycomb cushion has the highest for all rail angles. When it comes to subjective comfort rating, the baseline cushion has the highest comfort rating, while the air-cushion has the lowest for all rail angles. The results for blood pressure and pulse rates are inconclusive. However, the oxygen blood flow (basal Sp02) favors the baseline cushion with the highest oxygen flow over the period of the testing, somewhat similar to the comfort rating.

Full textAbstract:
Purpose – to reveal the scientific approach to the regional policy in the field of research, use and increase the recreational potential of the regions of Ukraine, creating an effective mechanism for the development of the recreational system of the region due to an in-depth study of the recreational system potential, the quality of the recreational environment and highlighting its special structure. As a sub-goal of the study was determined the identification of factors affecting the competitiveness of the recreational system of the regions, which will make it possible to clarify the directions of activities to increase the competitiveness of the tourism and recreation sector of the economy of Ukraine. Findings – the paper proposes the mechanism of well-balanced mutual development of humanʼs health and recreational system management. Research limitations – the study addresses the problem of using recreational potential in such a way that, as a result of its use, the least damage is inflicted on the territory and on the population. To determine the direction of development were identified as “sore spots” groups of the recreational system. To solve this problem has been proposed a mechanism for the balanced development of the recreational system, which will allow: 1) to maintain and develop the existing recreational potential; 2) to increase the share of regional profits from the use of recreational potential. Methodology – the methodology and research tools are based on the methods of theoretical generalization, refinement of the conceptual apparatus, logical-structural modelling, scientific argumentation, and comparative analysis. Practical implications – the practical significance lies in the fact that the article reveals the problematic issues of recreation in Ukraine and suggests a mechanism for the management and sustainable development of the countryʼs recreational potential. The use of the proposed mechanism will lead to an increase in the incomes of the regions from the exploitation of the recreational potential and will create the conditions for the preservation of the recreational systems themselves. Originality/Value – the article value lies in the fact that it proposes a mechanism for the balanced development of the recreational system and the person in it; carried out the allocation of recreational management in a special function of the recreational system. The relationship between the development strategies of the recreational system and the assessment of the recreational competitiveness of the region is shown.

In ASME 2010 Pressure Vessels and Piping Division/K-PVP Conference. ASMEDC, 2010. http://dx.doi.org/10.1115/pvp2010-25886.
Full textAbstract:
This paper describes the finite element considerations employed in a seismic response spectrum analysis of a skirt supported, liquid containing pressure vessel. Like many axisymmetric cylindrical vessels, the gross seismic response to an input response spectrum can be categorized by a simplified lump mass model that includes both the mass of the vessel proper in combination with the associated mass of multiple fluid levels. This simplified response may be utilized to determine the initial sizing of the supporting configuration, such as a skirt, but lacks the ability to properly address the fluid-structure interaction that creates sloshing loads on the vessel walls. The most obvious method to address the fluid-structure interaction when considering the finite element method is to build a three-dimensional model of the vessel proper, including, but not limited to the shell courses, the top and bottom heads (for a vertical vessel), and the support skirt. The inclusion of the fluid effects may now be incorporated with a “contained fluid” finite element, however, for vessels of any significant volume, the number of finite elements can easily exceed 100,000 and the number of degrees of freedom can sore from as few as 300,000 to as many as 500,000 or more. While these types of finite element analysis problems can be solved with today’s computer hardware and software, it is not desirable in any analysis to have that volume of information that has to be reviewed and approved in a highly regulated nuclear QA environment (if at all possible). With these items in mind, the methodology described in this paper seeks to minimize the number of degrees of freedom associated with a response spectrum analysis of a liquid filled, skirt supported vertical pressure vessel. The input response spectra are almost always provided in Cartesian coordinates, while many, if not most liquid containing pressure vessels are almost always axisymmetric in geometry without having benefit of being subjected to an axisymmetric load (acceleration in this case) due to the specified seismic event. The use of harmonic finite elements for both the vessel structure and the contained fluid medium permit the efficiencies associated with an axisymmetric geometry to be leveraged when the seismic response spectrum is formulated in terms of a Fourier series and combined to regain the effects of the two orthogonal, horizontally applied accelerations as a function of frequency. The end result as discussed and shown in this paper is a finite element model that permits a dense mesh of both the fluid and the structure, while economizing on the number of simultaneous equations required to be solved by the chosen finite element analysis.
