Experimental study of second sound quench detection for superconducting cavities

Superconducting rf cavities are used in particle accelerators to provide energy to the particle beam. Such cavities are mostly fabricated in niobium and often operated in superfluid helium. One of their limits of operation is the appearance of a local quench, initiated by a local field enhancement due to a defect, which leads to a normal conducting transition of the cavity. Localizing the quench area can be achieved with temperature mapping systems. Another method is the use of second sound wave propagation in superfluid helium. Measuring the time of propagation of these waves from quench location to special sensors, called oscillating superleak transducers (OSTs), and using their well-known velocity should allow trilateration. However, most of the experimental measurements on cavities show premature signals, i.e., the second sound signals arrive earlier on the OSTs than expected. This paper presents several quench experiments on cavities equipped with OSTs and temperature mapping quench detection systems. Two hypotheses can explain the observed premature signals. The first one assesses faster propagation in helium. An experimental setup has been developed for testing this hypothesis, where second sound is created by a localized heater in a controlled environment up to 4 . 3 kW = cm 2 and 2.8 J. Premature signals could not be verified in this setup. A second hypothesis based on a simple model including several processes in niobium and second sound propagation in helium is discussed. The model improves significantly the prediction of the times of arrival of the second sound waves. The overall study shows that the processes in niobium play a prominent role in the
Exploring the impact of interprofessional taught modules and placement experience on the development of professional identify and understanding of roles in first year mental health students

Mental health services are under continuous pressure to develop multidisciplinary service models in response to government policy. Mental health professionals, however, continue to be trained in isolation with little preparation for working within a multidisciplinary environment. This thesis explored the development of professional identification amongst nine students in their first year of qualifying training. It focussed on their understanding of their role and the roles of other mental health professionals, specifically nursing, social work and occupational therapy. It also focused on the impact of interprofessional education (IPE) and work-based placements. The research undertaken in this thesis was framed by a social constructionist approach and utilised semi-structured interview data collection methods, discourse analysis and the analysis of course syllabii to explore student experiences. The findings indicate that there may be benefits that can be achieved through IPE regarding enabling students to understand their professional roles within the broader context of health and social care. IPE can offer a means of preparing social work, nursing and OT students for the multidisciplinary team environments that they will be required to work within should they choose to work in mental health services. This thesis suggests that the impact of placement experiences within the first year of study on identity and knowledge of own roles and those of other professions, whether in MDTs or uni-disciplinary teams is significant. These findings indicate that consideration should be given by education providers to the weight and significance of the first practice based experiences, as a potent learning and development experience that can shape professional identity and understanding.
Existence and blow up of solutions to the $ 2D $ Burgers equation with supercritical dissipation

This paper is concerned with the Cauchy problem for a fractal Burgers equation in two dimensions. When \begin{document}$ \alpha\in (0, 1) $\end{document} , the same problem has been studied in one dimensions, we can refer to [ 1 , 17 , 24 ]. In this paper, we study well-posedness of solutions to the Burgers equation with supercritical dissipation. We prove the local existence with large initial data and global existence with small initial data in critical Besov space by energy method. Furthermore, we show that solutions can blow up in finite time if initial data is not small by contradiction method.

The result showed that the applied of water hyacinth (Eg) was the best treatment in decreasing parameter of tempe waste water quality with efficiency value, such as turbidity of 85.03%; TSS of 66.44%; COD of 59.11%; BOD of 77.91% and N of 61.77%. Keywords: phytoremediation, tempe waste water, water hyacinth, water lettuce, water spinach
Exploring Family Planning the Perception among Women of Reproductive Age Group in a Slum of Kolkata.

Introduction: The single most important problem that India is facing now is the uncontrolled growth of population. In spite of availability of a wide range of contraceptives, mass media campaigns and IEC programs for family planning, population control still remains a distant dream to achieve. The roots of the factors influencing family planning issues are entrenched in the socio-cultural milieu of Indian society. Objectives: To determine the pattern of family planning practices and to find out its association with different socio-demographic characteristics if any. Methodology: A cross-sectional, community based study was conducted among 120 married women of 15-49 year age group in a slum of Kolkata. Results: Knowledge about different family planning methods was present among 115(95.8%) of women. The number of current users of family planning methods was 88(73.3%). Among those who were currently using contraceptive methods 76(86%) used modern methods, and 12(10%) used natural methods. Among the modern methods, permanent method i.e. female sterilization was adopted by 41(46.7%) of women followed by oral contraceptive pills 16(18.1%), condoms 13(14.7%) and IUDs 6 (6.8%). Current contraceptive use increased significantly with increase in the age of the mother [OR=0.37 (0.16-0.87)], number of living children [OR=0.19(0.07-0.87)] and with per capita income [OR = 2.73 (1.01-7.31)] which remained significant even after adjustment with other covariates such as age of the women at marriage, education of the women, husband’s occupation and education. Conclusion: Although knowledge about contraceptive methods seemed adequate, the perceptions and practice of contraception seemed to be dismally poor.

The role of attentional focus on walking efficiency among older fallers and non-fallers

Abstract Background This study evaluated the effect of attentional focus instructions on movement efficiency during a level-ground walking task in older adults with and without a history of falls. Methods One hundred and thirty-four community-dwelling older adults were categorised into older fallers (OF) (n = 37) and older non-fallers (ONF) (n = 97). Each participant was instructed to walk at a self-selected pace along a 6 m walkway under three attentional focus conditions (i.e. internal, goal-directed and control) for a total of nine trials. Average muscle activity indices of lower limb co-contractions were measured using surface electromyography. Results Both shank and thigh muscle co-contractions were higher in OF than in ONF in all three conditions. OF also demonstrated higher shank muscle co-contraction under the internal relative to the goal-directed condition, with no such change observed in ONF. Conclusion Despite no significant between-group differences in functional balance and balance confidence, relative walking inefficiencies were observed in OF compared with ONF. This finding demonstrates the debilitating consequences of falling that can occur with relative independence from various physiological or psychological factors that are commonly associated with falling and used to rationalise behavioural change. We also provide evidence that OF are more susceptible to conditions that provoke them to allocate attention internally. Therefore, in clinical contexts (e.g. gait rehabilitation), verbal instructions that refer to body movements (internal focus) might serve to compromise movement efficiency in older adults with a history of falls. Such changes will, theoretically, lessen the ability to react efficiently to changing environments experienced in daily life.
A Credit Spread Puzzle for Reduced-Form Models

Reduced-form models of default calibrated to expected default losses and comovements between default losses and an equity-based pricing kernel generate CDS spreads that tend to fall below historical values. In frictionless markets, resolving this credit spread puzzle requires credit-market investors, especially those in high-quality debt, to be more risk adverse than equity-market investors. In the absence of market segmentation, however, the puzzle points to a liquidity component that, depending on the model specification, can account for more than half of historical CDS spreads. These findings caution against fitting reduced-form models to CDS spreads without accounting for market segmentation or frictions.
Design of a High Efficiency DC-DC Converter with Wide Bandgap Devices for Aircraft Applications

This thesis focuses on developing a 5 kW isolated DC-DC step-down converter. Work is categorized into designing, modelling, optimization and simulations. Our goal is to reach > 95 % efficient converter that fulfills strict weight, volume and thermal requirements and EMI standards of the aviation industry. Constantly improving semiconductor industry produces ever-improving switching devices, that allow access to higher switching frequencies. These developments allow for leaps in converter design. To utilize the development in material technology, the modelling of high-frequency effects in magnetic components needs to be reliable and accurate. This thesis focuses on numerically modelling these effects in MatlabTM environment. Results obtained from the mathematical model proved to be a good starting point for selecting materials and required windings in a transformer and for overall optimization of the converter and simulations confirm operation of the converter.
Correlation between Tissue Pathology and Vitreal Levels of hsCRP, IL-6 and TNF-α in Diabetic Rats Treated with Aspirin

Diabetic retinopathy is a progressive neurological complication of diabetes. Microvascular changes accompany diabetic retinopathy and may result in blindness. Inflammation has been shown to underlie the pathogenesis of diabetic retinopathy. We investigated the correlation between inflammatory markers and tissue pathology in diabetic rat eye. We also tested the role of anti-inflammatory drugs (aspirin) in the prevention of diabetic retinopathy. Ninety male Wistar albino rats were used in the present study. Rats were equally divided into 3 groups; control group, diabetic (streptozotocin, 50 mg/kg i.p), and aspirin-treated (ASPIRIN PROTECT, 2 mg/kg/d) diabetic group. All animals were scarified 6 months after the induction of diabetes. Histology and immunohistochemistry were conducted on the tissues of the rats' eyes, while vitreous samples were collected for the measurement of hsCRP, IL-6 and TNF-α. The levels of the measured inflammatory markers were significantly higher in diabetic rats, and notably correlated to the histo-pathological changes. Treatment with aspirin lowered the elevated levels of hsCRP, IL-6 and TNF-α with a considerable protective effect on the affected tissues. Our data suggest the possibility that hsCRP, IL-6 and TNF-α may be a cause of diabetic retinopathy progression and not necessarily a result. We also concluded that anti-inflammatory drugs which target hsCRP, IL-6 and TNF- α may play a crucial role in the prevention of diabetic microvascular complications.
User preferences on transformations of shopping centers into private urban public spaces: The case of Izmir, Turkey

With the spread of globalization, shopping centers are becoming a part of the urban lifestyle in many countries, including Turkey. Their numbers are increasing rapidly in metropolitan areas. In addition to their retail outlets, these newly designed, well-kept shopping centers offer facilities that enable people to pursue leisure activities and engage in social interaction. The study demonstrates that Turkish people using shopping centers as a private public space (community space) rather than simply a shopping space. To explore this phenomenon, we researched the activities and characteristics of a centre that attracts mostly Turkish people. To explore their implications for different centre characteristics and activities, user characteristics, such as gender, age and occupation, were investigated via survey and interviews. A field survey was carried out in EGE Park MaviAŸehir shopping centre in Izmir, the third largest city in Turkey. The centre is in a suburban area that was recently established as a high-income housing settlement. The results of statistical analysis of the data show that shopping centers corporate community space functions in, and attracts their users especially teenagers for its physical attractiveness, entertainment and leisure facilities and social interaction more than the shopping activities. Key words: Shopping centre, private public space, user preferences, transformation, physical attractiveness, entertainment and leisure facilities, socializing.

Parental acceptance of the Human Papillomavirus vaccination among South Asian immigrants living in the Midwest USA

Khan, Samina S. M.P.H. , Purdue University, August 2014. Parental Acceptance of the Human Papillomavirus Vaccination among South Asian Immigrants Living in the Midwest USA. Major Professor: Gerald Hyner. The objective of this investigation was to initiate the first study of Human Papillomavirus (HPV) vaccination acceptance among South Asian parents living in the USA. The primary focus of this study was to identify the knowledge, awareness, acceptance, and those factors that influenced South Asian parents’ decision regarding the vaccination of their children against HPV. This research utilized a cross-sectional study design conducted among South Asian parents in Indianapolis and the Greater Lafayette area of Indiana. The data were collected online using Qualtrics survey software. The survey included six segments containing questions on: socio-demographic information, knowledge and source of information about HPV, cervical cancer, genital warts, and other relevant questions. The study sample consisted of 136 participants which was diverse in terms of age, sex, country of origin, and religion. The participants were highly educated with 71.3% having or completing a graduate degree. Among all participants, 58.8% were females and 41.2% were males. In this study females were more knowledgeable than men. Duration of stay in the US, annual household income and family history of cancer were the key determinants of HPV related knowledge. More parents were willing to vaccinate
Antipsychotic medications: linking receptor antagonist properties to neuropsychological functioning

Antipsychotic medications are thought to contribute to the neuropsychological impairments associated with schizophrenia, but specific links with pharmacology are not well established. This study investigated associations of specific medication properties with neuropsychological and psychiatric symptoms in a first-episode psychosis sample. Medication doses and indices of receptor antagonism were used to estimate dopamine antagonist, serotonergic antagonist, and anticholinergic loads (i.e., impact of participants’ medications on those receptors). Results indicated that higher anticholinergic load was associated with poorer verbal long-term memory and higher D2 load was associated with poorer motor functioning. Additional exploratory analyses indicated that in non-smokers, higher D1 load was associated with more severe negative symptoms, whereas higher 5HT2A load was associated with less severe negative symptoms. Furthermore, in smokers, higher 5-HT2A load was associated with poorer verbal working memory. These results support the validity of estimating medication receptor loads to elucidate specific and dissociable effects of antipsychotic medication properties.
Shouldice Versus Lichtenstein Hernia Repair Techniques: A Prospective Randomized Study

Background : The objectives of this study was to compare the tension-free mesh (Lichtenstein), and the 4-layer tissue repair (Shouldice) techniques of inguinal hernia surgery and to determine to what extent doctors in a general surgical unit were able to reproduce the excellent results reported from specialist hernia centres. Methods : Patients with primary unilateral inguinal hernia were over an 18 month period randomized to either the Shouldice group (experiment) or to the Lichtenstein group (control). The operating time, convalescence, hospital stay, postoperative analgesic consumption and complications, were assessed and compared. Results : There Lichtenstein group had a shorter operating time but had a higher occurrence of persistent postoperative pain compared to the Shouldice group. There was no significant difference in convalescence between the two groups and no recurrences have been recorded in either group. Conclusion : Despite Shouldice being more challenging to perform compared to Lichtenstein, the postoperative results are comparable. Our experience shows that both procedures can be taught to medical officers who can perform them with relative safety, efficacy and reproducibility to surgeons. Shouldice method being the more cost effective procedure should be encouraged in men with primary unilateral inguinal hernias.
Atomic-Scale Observation of Titanium-Ion Shifts in Barium Titanate Nanoparticles: Implications for Ferroelectric Applications

Ferroelectric nanoparticles (NPs) have attracted considerable attention owing to their size effect on the ferroelectricity and their possible application toward future electronic devices such as multilayer ceramic capacitors and ferroelectric random access memory. The ferroelectricity disappears for NPs smaller than the critical size, which has been an obstacle for the development of materials. Although the fundamental mechanisms of the size effect should be clarified to overcome this problem, the understanding has been made ambiguous by the fact that NPs of different morphologies prepared by different methods exhibit various critical sizes, which indicates that more investigations should be conducted on the appearance/disappearance of ferroelectricity in NPs. To gain insight into the appearance of ferroelectricity, atomic-scale characterizations are beneficial because the ferroelectricity is closely related to the atomistic structures. In the present study, atomic-scale scanning transmission electron mic.
Perceived Usefulness of Reciprocal Peer Teaching Among Doctor of Physical Therapy Students in the Gross Anatomy Laboratory

Background and Purpose. Reciprocal peer teaching (RPT) describes an education method whereby students alternate between teacher and student roles. The use of RPT has not been described in previous physical therapist education literature. The first purpose of this study was to assess the perceived usefulness of RPT among first‐year Doctor of Physical Therapy (DPT) students as a method for teaching and learning human anatomical relationships in the dissection laboratory. The second purpose was to determine if exposure to RPT during a semester course in gross anatomy had an effect on students' anatomy course grade. Subjects. Participants were 27 professional (entry‐level) DPT students, graduating class of 2008, who participated in the RPT experience in the gross anatomy laboratory, and 21 DPT students, graduating class of 2007, who did not participate in the RPT experience. Methods. Students in teacher roles worked in pairs and rotated among their fellow classmates within the laboratory, illustrating anatomical concepts previously discussed in the classroom. At the completion of the course, students were queried about the perceived usefulness of the RPT experience using a 12‐item survey instrument that used a 5‐point Likert scale. The internal consistency of the survey instrument was estimated by Cronbach's alpha. The median anatomy course grade (MACG) for the class of 2008 and class of 2007 was compared statistically using a Mann‐Whitney U‐test. Results. Cronbach's alpha was 0.85. Students provided the strongest responses for survey items that assessed the perceived usefulness of RPT for teaching and learning anatomical relationships (median Likert scores ranged from 4 to 5). MACG for the class of 2008 (MACG = 3.70) was significantly greater than the MACG for the class of 2007 (MACG = 3.30; Z = ‐2.19, P = .029). Discussion and Conclusion. First‐year DPT students perceived the usefulness of RPT in the dissection laboratory as a valuable resource for teaching and learning anatomical concepts. In addition, the RPT experience was also perceived to be helpful when communicating with patients. Furthermore, exposure to RPT had a significant effect on the MACG.
