Partial discharge simulation under various applied voltage waveforms

In high voltage power equipment, partial discharge (PD) measurement is widely used in the performance assessment of an insulation system. However, from modelling of PD, a better understanding of the phenomenon may be attained. PD activity within a void in a solid dielectric insulation material is influenced by many factors. One of the factors is the applied voltage. Different types of the applied voltage yield in different PD patterns and the condition for breakdown of insulation to occur. In this work, PD activity under various types of the applied voltages has been studied. A finite element analysis (FEA) software was used to simulate PD occurrence within a void in a dielectric material. The applied voltages that were considered are AC sinusoidal, damped AC and impulse voltages. PD patterns were observed through phase resolved partial discharge (PRPD) patterns. The obtained result may improve an understanding on PD behaviour under different types of the applied voltage. It may also assist in insulation diagnostics and performance assessment of an insulation system.
A necessidade do acaso: um convite ao diálogo filosófico

Um posicionamento filosofico realista que nao coloque em duvida a inteligibilidade do universo ao qual investiga e nao se pretenda detentor de qualquer privilegio para alcancar a verdade admite a falibilidade de qualquer representacao da realidade, nao vendo motivo para fugir ao dialogo com aqueles que propoem explicacoes diferentes das suas, mesmo que por vezes com elas conflitantes.
Design of a Ring Probe-Fed Metallic Cavity Antenna for Satellite Applications

This communication presents the design of a novel ring probe-fed metallic cavity antenna with circular polarization for satellite applications. The motivation for this work is to propose a novel design that has the advantage of electrically large size and improved 3-dB axial-ratio bandwidth in the Ku-band and other higher-frequency bands as well as low cost and easy fabrication. The resonant mode and circular polarization of the proposed antenna is excited by a ring probe. To verify the design concept, a brass C-band antenna prototype of the proposed antenna is fabricated and measured. The measured impedance bandwidth for |S11| ≤ -10 dB and 3-dB axial-ratio bandwidth are 1.08 GHz (6.94 GHz to 8.02 GHz) and 0.80 GHz (7.11 GHz to 7.91 GHz), respectively. The 3-dB axial-ratio bandwidth of the antenna is 10.7%. The measured gain is about 8.3 dBic across the whole 3-dB axial-ratio bandwidth. Very good consistency between the measurement and simulation for the return loss and radiation patterns is achieved.
Correlation Coefficient based Loss Differentiation Algorithm (CCLDA) for TCP vis-à-vis traditional LDAs

This paper proposes an LDA to help us tune a wireless network thus enabling better network utilization and throughputs, which in turn result into increased customer satisfaction. Correlation between various TCP parameters is used. CC-LDA uses a statistical approach but ensures fewer loads on a client side processing applications. Various samples were collected from the IPDM server and were analyzed. I also propose a monitoring lifecycle using CC-LDA involving a knowledge base to gain some priori knowledge through tests. The paper ends with a comparison with other existing LDAs.
Oral delivery of particulate prostate cancer vaccine: In vitro and in vivo evaluation

Background: Various approaches have been evaluated for generation of efficient immune response against tumor antigens. Our approach exploits usage of particulate delivery to generate immune response against prostate cancer antigens. Purpose: The aim of this study was to evaluate the efficacy of prostate cancer vaccine derived from a murine prostate cancer cell line, TRAMP C2 in murine model via oral route using aleuria aurantia lectin as a targeting ligand for M-cells in the intestinal Peyer’s patches. Methods: The whole cell lysate (WCL) was obtained from TRAMP C2 murine prostate cancer cell line and was formulated into particles using one step spray drying process. For in vivo studies, 4–6 week old C57BL/6 male mice were vaccinated orally biweekly for 10 weeks. Serum samples were analyzed at regular intervals to determine serum IgG levels. The mice were then challenged with live TRAMP C2 cells to determine efficacy of the vaccine. Results: The serum IgG levels of vaccinated animals were higher compared to that of the controls. Moreover, the tumor growth was retarded significantly in the vaccinated mice compared to that of controls (p < 0.001). Conclusions: The above findings suggest that oral particulate WCL vaccine can trigger an immune response against prostate cancer antigens.
Hemodynamic Effects of Endobronchial Application of Ornipressin versus Terlipressin

Background: Ornipressin and terlipressin, two ADH-derivates, are instilled endobronchially for bronchoscopy- related bleeding without sufficient evidence of efficacy, nor safety. Objectives: To compare the immediate hemodynamic effects of ornipressin and terlipressin used for procedure-related bleeding during flexible bronchoscopy. Methods: This retrospective study included patients referred for flexible bronchoscopy who needed administration of ornipressin (15 patients) or terlipressin (15 patients) for procedure-related bleeding. Endobronchial ornipressin (5 IU) or terlipressin (0.5 mg) was administered through the bronchoscope when bleeding persisted for 2 min of continuous suction, or when bleeding was considered increasing in time or major. Hemodynamic data were collected before, during and after administration of either drug. Results: Biopsy-associated hemoptysis requiring medical treatment occurred in 110 (4.2%) of 2,592 bronchoscopies. After administration of ornipressin, no significant change in heart rate or blood pressure was observed. Following terlipressin instillation, heart rate increased from 93 ± 17 to 101 ± 22 b.p.m. (p = 0.03), and blood pressure decreased from 107 ± 14 to 101 ± 17 mm Hg (p = 0.04). Oxygen saturation under supplemental nasal oxygen was not different in both groups. None of the 110 patients died from bronchoscopy-related hemoptysis or needed further intervention to stop bleeding or prolonged monitoring because of hemodynamic instability. Conclusions: In contrast to ornipressin, administration of terlipressin is associated with significant changes in heart rate and blood pressure. However, these changes are of minor clinical importance, and terlipressin can be safely given for bronchoscopy-associated bleeding.
Malignant Disease in Von Recklinghausen's Neurofibromatosis

In the old nomenclature the terms primary and secondary sarcoma of Garre (1892) were used in reference to malignant tumours of the nerve sheath occurring respectively without or with associated generalized neurofibromatosis. Evidence suggestive of the origin of a tumour from nerve sheath comprises: (1) Entry of nerve into tumour. (2) Presence of nerve fibres within the tumour. (3) Extension of tumour tissue along nerves marginal to it. (4) Histological features including whorling and myxoid change (Willis 1953). In practice such features are present in only a proportion of sarcomas in von Recklinghausen's disease. The fact that tumours of nerve sheath origin may give no evidence of this is the basis for the contention of Stewart & Copeland (1931) and others that probably many fibroblastic tumours not demonstrably related to nerve are nevertheless of nerve sheath origin. The study of 'primary' sarcomas of nerve is the study of soft tissue sarcomas as a whole. This paper reports the findings in 14 cases of malignancy in neurofibromatosis. The frequency of malignant change in von Recklinghausen's disease is difficult to assess. In hospital cases an aggregate of four series (Heard 1962) revealed 33 sarcomas in 195 cases (17 %). Obviously this does not represent the risk of malignancy in the patient found incidentally to have neurofibromatosis. This risk remains unknown mainly because of difficulty in establishing criteria of von Recklinghausen's disease, and in enumerating the many uncomplicated cases in patients who do not seek medical advice. <]4 LU 3
When Do First-Year College Students Drink Most During the Academic Year? An Internet-Based Study of Daily and Weekly Drinking

Abstract Objective: The authors investigated the alcohol consumption trajectories among first-year university students. Participants: A sample of 415 students attending a large university in Southwestern Ontario, Canada, was recruited. Methods: Students completed a baseline questionnaire and 26 weekly brief Internet surveys assessing alcohol consumption from September 2006 to April 2007. Results: Findings indicated that alcohol consumption varies considerably as a function of time of the academic year. Overall trends indicate that students drink more heavily at the beginning of each semester and less during exam periods. Daily patterns indicate that most drinking occurs on weekends. The highest drinking days in the first academic year included Halloween, New Year's Eve, and St. Patrick's Day. Conclusions: The present study provides evidence that periods of high and low alcohol consumption are contingent upon specific events and the time of the year.
Effect of Abciximab Therapy in Patients Undergoing Coronary Angioplasty for Acute ST-Elevation Myocardial Infarction Complicated by Cardiogenic Shock.

BACKGROUND The effect of abciximab on survival in patients with ST-elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS) undergoing primary percutaneous coronary intervention (PCI) is not clear. METHODS AND RESULTS: We evaluated outcome in 410 consecutive patients with STEMI and CS who underwent PCI treated without (n=123) or with (n=287) abciximab. The endpoint was survival at 1-year follow-up. The predictors of death at 1 year were also investigated. The groups with and without abciximab had similar survival at 1-year follow-up. Propensity score-adjusted Cox proportional hazards model identified age (adjusted hazard ratio [HR], 1.02; 95% confidence interval [95% CI]: 1.01-1.03, P=0.001), oro-tracheal intubation (HR, 1.49; 95% CI: 1.12-1.96, P=0.05), post-PCI TIMI flow grade 0-1 (HR, 2.08; 95% CI: 1.52-2.83, P=0.0001) but not abciximab use (HR, 1.08; 95% CI: 0.70-1.60, P=0.60) as independent predictors of death at 1-year follow-up. Cox adjusted 1-year survival rates were 42.8% and 51.6%, (P=0.56) in patients treated without vs. with abciximab, respectively. CONCLUSIONS Patients with STEMI complicated by CS undergoing PCI treated with or without abciximab have similar 1-year survival rates; age, final TIMI 0-1 and oro-tracheal intubation are predictors of death.
Balancing rigour and relevance in guideline development for depression: the case for comprehensive cohort studies.

PURPOSE Clinical guidelines for the treatment of depression have not yet realized their potential for improving the delivery of the psychological therapies within national healthcare systems. Current guidelines emphasize treatment efficacy and issues in service delivery are relatively neglected. Hence, there is a hierarchy of evidence in which randomized efficacy trials are given primacy over naturalistic (i.e. practice-based) data. Such a strategy is inadequate to address important questions about best delivery of safe and acceptable psychological therapies and exacerbates divisions between research and practice communities. METHODS Selected narrative review. RESULTS Both randomized controlled trials and practice-based studies have shortcomings that can be ameliorated by the adoption of practical clinical trials embedded within large cohort studies - that is, comprehensive cohort studies. CONCLUSIONS Comprehensive cohort studies have the potential to deliver an evidence base which is both rigorous and relevant. This could satisfy the scientific community as well as allowing practitioners and service users to be fully involved and committed to the process of collecting evidence and implementing guidance. We argue this would be a sound foundation upon which to build an evidence base upon which to develop future clinical guidelines for depression.
Periodic Breathing

Periodic breathing (PB) has been described in normal adults’ and newborns’ who are living at high altitude. It has also been noted in adults with central nervous system (CNS) disturbance^,^. ^ in cardiac f a i l ~ r e , ~ ~ and during hypoxemia. lo,ll It has been found in excessive amounts in the preterm infant12 and in some full-term infants,I3 as well as in some infants who have apnea of infancy (AOI),I4-l5 in some who are victims of the sudden infant death syndrome (SIDS) and have a history of A01 or a family history of SIDS,I6 and in some who are siblings of SIDS victims (SS). ” In addition, studies by Southall et al. have suggested a relationship between PB and SIDS in some apparently normal infants who had no family history of SIDS. Because PB with a very similar pattern is found in multiple clinical settings, including apnea and sudden death, and because the origins of PB in an individual subject are unexplained, a computer model of respiratory control was developed. ” By using this model, one can determine the specific type and magnitude of changes in the respiratory control system which are necessary to generate an unstable breathing pattern. The maximum instability is demonstrated in this model by a pattern of periodic respirations alternating with periodic apnea. ” Respiratory control has been studied by many physiologists, using multiple variable^'^-'^ to describe the three basic components of the control system: (1) the controller, which represents the CNS input for directing ventilation, ( 2 ) the controlled system or total body gas storage, and (3) the feed-back delay or time necessary for blood to travel from the controlled system to the controller. In general, these models describe an equilibrium among the key components. This equilibrium encourages restabilization following a disturbance (e.g., a sigh) if the loop gain is substantially less than 1.0. However, if the gain exceeds 1.0, instability is perpetuated, as demonstrated by oscillatory breathing which grows to a maximum and is sustained. These models have not been experimentally validated, primarily because they included 15 or more physiological variables which, basically, are impossible to measure on any one subject at any one time. Carley and Shannonlg have developed a minimal model that includes 5 physiological variables, all of which are measured in about 20 min in adults. Loop gain depends on the interaction of these 5 variables and determines the relative stability of the chemoreceptor control system. These variables are (1) central chemosensitivity to carbon dioxide, ( 2 ) mixed venous Pco2, (3) cardiac output, (4) circulation delay, and (5) mean lung volume for C 0 2 (functional residual capacity of the lungs plus half of the mean tidal volume). This model has now been validated in awake (n = 15) and asleep (n = 22) young healthy adults. In addition, a simulation model has been developed26 that allows manipulation of variables singly or in combinations.
Étude de la fiabilité à long terme des transistors HEMT à base de GaN

Les performances des HEMTs AlGaN/GaN sont en passe de devenir une technologie de reference pour les applications de forte puissance dans le domaine radiofrequence. Cependant, le manque de retour d'experience sur la fiabilite de ces dispositifs se fait ressentir chez les industriels des domaines de la defense, de l'automobile et des telecommunications a cause de la jeunesse de cette filiere. Cette etude se porte donc sur la fiabilite a long terme de transistors HEMT AlGaN/GaN de puissance en regime RADAR. Elle repose notamment sur des caracterisations electriques des composants, le developpement d'une methode athermique de caracterisation de pieges ainsi que le stress de ces transistors sur un banc de vieillissement dedie. La somme des caracterisations avant, pendant et apres vieillissement ainsi que les analyses micro-structurales permet de definir des hypotheses quant a l'origine physique des derives de performances de ces composants.
School Nurses and Teachers

School nurses and middle and high school teachers (N = 107) participated in a survey that explored their attitudes and behaviors related to the inclusion of breastfeeding content to highlight the scientific and exceptional health advantages of breastfeeding and to promote a breastfeeding culture. Although some participants believed that breastfeeding content should not be part of school curriculum, the vast majority (86.9%) agreed that the benefits of breastfeeding should be taught to high school students; and over half (57.9%) supported teaching about the value of breastfeeding to middle school children. School nurses are well positioned to promote healthy lifestyle behaviors among student populations and play a pivotal and important role in the promotion of a breastfeeding culture and related positive behaviors.
Dopamine efflux in the rat striatum evoked by electrical stimulation of the subthalamic nucleus: potential mechanism of action in Parkinson's disease

The precise mechanism whereby continuous high‐frequency electrical stimulation of the subthalamic nucleus ameliorates motor symptoms of Parkinson's disease is unknown. We examined the effects of high‐frequency stimulation of regions dorsal to and within the subthalamic nucleus on dopamine efflux in the striatum of urethane‐anaesthetized rats using constant potential amperometry. Complementary extracellular electrophysiological studies determined the activity of subthalamic nucleus neurons in response to similar electrical stimulation of the subthalamic nucleus. High‐frequency stimulation of the subthalamic nucleus increased action potential firing in the subthalamic nucleus only during the initial stimulation period and was followed by a cessation of firing over the remainder of stimulation. Electrical stimulation of the subthalamic nucleus with 15 pulses elicited stimulus‐time‐locked increases in striatal dopamine efflux with maximal peak effects occurring at 50 Hz frequency and 300 µA intensity. Extended subthalamic nucleus stimulation (1000 pulses at 50 Hz; 300 µA) elicited a similar peak increase in striatal dopamine efflux that was followed by a relatively lower steady‐state elevation in extracellular dopamine over the course of stimulation. In contrast, extended stimulation immediately adjacent and dorsal to the subthalamic nucleus resulted in an 11‐fold greater increase in dopamine efflux that remained elevated over the course of the stimulation. Immunohistochemical staining for tyrosine hydroxylase revealed catecholaminergic fibers running immediately dorsal to and through the subthalamic nucleus. Taken together, these results suggest that enhanced dopamine release within the basal ganglia may be an important mechanism whereby high‐frequency stimulation of the subthalamic nucleus improves motor symptoms of Parkinson's disease.
A hybrid approach to identifying sentiment polarity for new words

Microblog is a typical form of heterogeneous information. For this information, identifying sentiment polarity of new words plays a fundamental role in sentiment analysis. In this paper, we proposed a hybrid approach using both statistic and syntax information to identifying the sentiment polarity of new words. We first filter the raw tweets out some noises and segment the clean data with POS tagging. Next, we collect new words by filtering rules. Then, we assign each new word with a polarity using both statistics and patterns information. We evaluate our approach on a real dataset from Sina Weibo, achieving a relatively high F-score of 0.241 compared with the baseline of 0.22.
Parental prevention practices for young children in the context of maternal depression.

OBJECTIVE To assess the relationship between maternal depression and 4 parent-based prevention practices (use of car seats and electrical plug covers, presence of syrup of ipecac in the home, and reading to their child), using a large nationally representative follow-back sample. METHODS The maternal self-report components of 2 databases were used for this study, the 1988 National Maternal and Infant Health Survey and the linked companion 1991 Longitudinal Follow-Up Survey. A total of 7537 mothers with newborns in 1988 served as the subjects. Measures of the 4 prevention practices were extracted from the 1991 survey. Depressive symptom measures were derived from both surveys using the Center for Epidemiologic Studies-Depression Scale. Weighted bivariate and multivariate logistic analyses were used to assess the relationship between maternal depressive symptoms (trichotomized to depression at both time points, at 1 time point, and at neither time point) and parental prevention practices, while controlling for a wide variety of sociodemographic variables. RESULTS Mothers reporting a high level of depressive symptoms (Center for Epidemiologic Studies-Depression Scale score >/=16) reported significantly poorer prevention practices for car seat use, covering electrical plugs, and having syrup of ipecac in the home. High depressive symptoms were also related to a lower likelihood of daily reading, but only for those mothers presently living with a male partner. Engagement in all prevention practices, except having syrup of ipecac in the home, were less likely if the mother reported high levels of depressive symptoms at both time points versus a single time point. CONCLUSION Maternal depression may significantly impede parental prevention practices. As maternal depression is a treatable condition, screening and treating this disorder may contribute to improvement in childhood prevention practices and ultimately child health.
Temporalidad y texto: un problema de traducción

El propósito de este trabajo es una reflexión sobre el complejo problema de la temporalidad en francés y su funcionamiento discursivo. Nuestra aproximación comportará dos niveles. Por una parte, haremos un pequeño recorrido sobre nociones de tipo general tales como la temporalidad, el problema de la referencia en el texto y los diferentes tipos (deixis, anáfora y expresiones cronológicas), comportamiento temporal y aspectual de los tiempos en el texto. Por otra, intentaremos, dentro de una óptica contrastiva, analizar el funcionamiento temporal a través de un pequeño corpus de ejemplos de un relato traducido al español. Pondremos de relieve no sólo las áreas de dispersión, como tradicionalmente se hace, algunas de ellas de gran utilidad para el traductor, sino también aquellos puntos de encuentro, debido al fondo común romance, de los que extraeremos un cierto "saber" sobre el sistema temporal, uno de los temas más espinosos, pero a la vez más atrayentes de la lingüística.
New Unstable Variants of Green Fluorescent Protein for Studies of Transient Gene Expression in Bacteria

ABSTRACT Use of the green fluorescent protein (Gfp) from the jellyfishAequorea victoria is a powerful method for nondestructive in situ monitoring, since expression of green fluorescence does not require any substrate addition. To expand the use of Gfp as a reporter protein, new variants have been constructed by the addition of short peptide sequences to the C-terminal end of intact Gfp. This rendered the Gfp susceptible to the action of indigenous housekeeping proteases, resulting in protein variants with half-lives ranging from 40 min to a few hours when synthesized in Escherichia coli andPseudomonas putida. The new Gfp variants should be useful for in situ studies of temporal gene expression.
