Taylor Cone and Jetting from Liquid Droplets in Electrospinning of Nanofibers

Sessile and pendant droplets of polymer solutions acquire stable shapes when they are electrically charged by applying an electrical potential difference between the droplet and a flat plate, if the potential is not too large. These stable shapes result only from equilibrium of the electric forces and surface tension in the cases of inviscid, Newtonian, and viscoelastic liquids. In liquids with a nonrelaxing elastic force, that force also affects the shapes. It is widely assumed that when the critical potential φ0* has been reached and any further increase will destroy the equilibrium, the liquid body acquires a conical shape referred to as the Taylor cone, having a half angle of 49.3°. In the present work we show that the Taylor cone corresponds essentially to a specific self-similar solution, whereas there exist nonself-similar solutions which do not tend toward a Taylor cone. Thus, the Taylor cone does not represent a unique critical shape: there exists another shape, which is not self-similar. The exp.
Regional anesthesia in patients with pregnancy induced hypertension

Pregnancy induced hypertension is a hypertensive disorder, which occurs in 5% to 7% of all pregnancies. These parturients present to the labour and delivery unit ranging from gestational hypertension to HELLP syndrome. It is essential to understand the various clinical conditions that may mimic preeclampsia and the urgency of cesarean delivery, which may improve perinatal outcome. The administration of general anesthesia (GA) increases morbidity and mortality in both mother and baby. The provision of regional anesthesia when possible maintains uteroplacental blood flow, avoids the complications with GA, improves maternal and neonatal outcome. The use of ultrasound may increase the success rate. This review emphasizes on the regional anesthetic considerations when such parturients present to the labor and delivery unit.
The effects of Perceived Mobility and Satisfaction on the adoption of Mobile-based Assessment

Mobile-based Assessment is increasingly used in different educational settings. Its successful implementation though depends on user acceptance. While previous research provides evidence on acceptance of mobile learning and computer-based assessment, there are not many studies focusing explicitly on the acceptance of Mobile-based Assessment. This study examines the impact of Perceived Mobility, Satisfaction, Perceived Usefulness and Perceived Ease of Use on students' Behavioral Intention to Use Mobile-based Assessment. 47 secondary school students, using their mobile devices and Quick Response (QR) - coding technology, participated in an outdoor Mobile-based Assessment procedure during their visit in a Botanic Garden. Partial Least Squares (PLS) was used for the data analysis of the recorded students' perceptions about the Mobile-based Assessment. Results show that Perceived Mobility, Satisfaction, Perceived Usefulness and Perceived Ease of Use are all significant determinants of Behavioral Intention to Use mobile-based assessment. Several important implications for designing and implementing mobile-based assessment procedures are discussed.
Attitudes toward direct predictive testing for the Huntington disease gene. Relevance for other adult-onset disorders. The Canadian Collaborative Group on Predictive Testing for Huntington Disease.

OBJECTIVE To assess attitudes toward, and projected utilization of, direct mutation testing by individuals at risk for Huntington disease (HD). DESIGN Prior to the cloning of the gene for HD, a questionnaire concerning the use of a definitive test was constructed and mailed to 354 participants in the Canadian Collaborative Study for HD. Completed questionnaires were received from 250 participants (response rate, 71%). Persons were asked to indicate whether they would participate in a new predictive test that was either 100% accurate (the definitive test, requiring blood only from the proband) or only 99% accurate. RESULTS Most (72%) of the persons who had previously received a result in a predictive testing program said they would request testing in either situation. Significantly more persons would request the definitive test than the 99% accurate test (72% vs 58%; P < .02). Respondents for whom testing was uninformative in the linkage test program or who had previously received an increased-risk result were more likely to indicate they would use the test than those who received a decreased-risk result or chose not to have the original test (P = .0003). Less than half (46%) of the participants who initially chose not to have the linkage test said they would return for the new direct test. The major factor that has limited acceptance of predictive testing for this group is the concern about receiving an increased-risk result in the absence of any therapy to alter progression of the disease. CONCLUSIONS A direct mutation test for HD will most readily be accepted by persons who wanted but could not previously receive a result in the linkage test program and those who previously received an increased-risk result. In the absence of therapy, the majority of persons who previously chose not to have predictive testing are unlikely to participate in a new test despite improved accuracy. This has implications for the expected demands for testing services for other adult-onset genetic disorders.
Resonant LGS microsensor for scanning microdeformation microscopy

Scanning microdeformation microscopy (SMM) is a near field microscopy in the mesoscopic domain. Such a microscope has become an alternative to the high resolution acoustic microscope that operates at very high frequencies. SMM is based on a vibrating contact tip and piezoelectric detection. The lateral resolution is essentially related to the tip diameter. Classically, the SMM sensor is obtained by a complex mounting process. The tip is glued on a Si cantilever driven by a piezoelectric ceramic. Piezoelectric crystal is an alternative to get a monolithic vibrating cantilever. Quartz crystal, which is the most often used piezoelectric material, can be advantageously replaced by Langasite crystal because of its higher piezoelectric coefficients and its better temperature behaviour.
Response to Comments on “Productivity Is a Poor Predictor of Plant Species Richness”

Pan et al. claim that our results actually support a strong linear positive relationship between productivity and richness, whereas Fridley et al. contend that the data support a strong humped relationship. These responses illustrate how preoccupation with bivariate patterns distracts from a deeper understanding of the multivariate mechanisms that control these important ecosystem properties.
Transport and noise behavior of cascaded realistic tunnel barriers

We present a numerical investigation of the conductance and shot noise behavior of a cascade of realistic tunnel barriers, defined in a GaAs/AlGaAs heterostructure using negatively biased depletion gates. We show that, even in the presence of irregularities in the gate boundaries, strong localization dominates the transport through the device and consequently the shot noise suppression factor does not approach, increasing the number of barriers, the 1/3 limit characteristic of diffusive conductors.
Credit Constraints, Firm Investment and Growth: Evidence from Survey Data

We assess the impact of credit constraints on investment, inventories and other working capital and firm growth with a large panel of small and medium-sized enterprises from 12 European countries for the period 2014-2016. The data come from the Survey on the access to finance of enterprises (SAFE), a survey that is especially designed to analyse the problems in the access to external finance of European SMEs. The key identification challenge is a potential reverse-causality bias, as firms with poor investment and growth opportunities may have a higher probability of being credit constrained. We implement several strategies to overcome this obstacle: proxies for investment opportunities, lagged regressors, random effects and instrumental variables. Our findings suggest that credit constraints, both in bank financing and other financing (e.g. trade credit), have strong negative effects on investment in fixed assets, while the impact on firm growth and working capital is less robust.
INFORMATION-SEEKING BEHAVIOUR OF INTERNATIONAL ISLAMIC UNIVERSITY MALAYSIA LAW FACULTY MEMBERS

Adequate knowledge about the information needs and seeking behaviour of users is vital for developing library collections, services and facilities to meet their information needs effectively. The purpose of this study is to identify the information channels used by the International Islamic University Malaysia (IIUM) law faculty members, information sources preferred by them, methods employed for getting the needed information and their library use pattern. A questionnaire was distributed to 80 IIUM law faculty members and 66 filledin questionnaire s were returned, giving an overall response rate of 82.5 percent. It was found that respondents used various sources for acquiring the needed information. Books were ranked as the most important source for teaching and research purposes, followed by law reports and statutes. Respondents preferred to first consult their personal collection before resorting to other information providing sources and agencies. The Online Public Access Catalogue (OPAC) and CD-ROM were the most frequently used IT-based sources and facilities. E-mail was the most popular among the Internet-based services and applications. On the whole, respondents perceived IIUM library collections, services and facilities as adequate to meet their information needs effectively.
Relative Effectiveness of Central, Peripheral, and Abrupt-onset Cues in Visual Attention

The relative effectiveness of central arrow, peripheral arrow, and abrupt-onset cues was assessed in a character recognition task. On each trial, either a central or a peripheral arrow cue was presented 0, 100, or 200 msec before the appearance of a three-digit display. Two of the digits were “uncamouflaged” from previous figure-eight masks, whereas the third digit appeared abruptly in a previously empty space. Four different groups of subjects were run in factorial combinations of high or low expected validities for arrow and onset cues. In Experiment 1, arrow cues were located centrally, near the fixation point. Abrupt onsets showed larger cost-plus benefits than central arrows, except when subjects expected the central cues to have higher validity than the onsets. In Experiment 2, arrow cues were located peripherally, near the display digits, and abrupt onsets were again more effective in capturing attention except when peripheral cues had higher validity and led the onsets by 100 msec or more. In both experiments, the relative effectiveness of abrupt onsets decreased with arrow SOA. The results were consistent with a model in which automatic and voluntary processes interact in their control of attentional resources.
Effects of cigarette smoking on HDL quantity and function: Implications for atherosclerosis

Cigarette smoking has been identified as an independent and preventable risk factor for atherosclerosis and cardiovascular disease. Population studies have shown that plasma high density lipoprotein (HDL) cholesterol levels are inversely related to the risk of developing cardiovascular disease. Cigarette smoking is associated with reduced HDL cholesterol levels. Cigarette smoking can alter the critical enzymes of lipid transport, lowering lecithin: cholesterol acyltransferase (LCAT) activity and altering cholesterol ester transfer protein (CETP) and hepatic lipase activity, which attributes to its impact on HDL metabolism and HDL subfractions distribution. In addition, HDL is susceptible to oxidative modifications by cigarette smoking, which makes HDL become dysfunctional and lose its atheroprotective properties in smokers. Therefore, cigarette smoking has a negative impact on both HDL quantity and function, which can explain, in part, the increased risk of cardiovascular disease in smokers. J. Cell.

Requirement of Histidine Kinases HP0165 and HP1364 for Acid Resistance in Helicobacter pylori

ABSTRACT In this study, we investigated a potential requirement of two-component signal transduction systems for acid resistance in Helicobacter pylori. In comparison to a wild-type strain, isogenic strains with null mutations in either HP0165 or HP1364 histidine kinases were impaired in their ability to grow at pH 5.0. The growth of complemented mutant strains was similar to that of the wild-type strain. H. pylori DNA array analyses and transcriptional reporter assays indicated that acid-responsive gene transcription was altered in the HP0165 and HP1364 null mutant strains compared to the parental wild-type strain. These results indicate that intact HP0165 and HP1364 histidine kinases are required for acid resistance in H. pylori.
THE PATTERNS OF PULMONARY CIRCULATION IN PULMONARY ATRESIA

Pulmonary atresia implies complete organic obstruction to normal direct outflow from the right ventricle to the pulmonary trunk. When such obstruction is present, survival is dependent on diversion of the systemic venous return to the left side of the heart through the atrial or the ventricular septum with subsequent flow of blood to the lungs through a persistent patent ductus or through bronchial or other anomalous vessels arising from the aorta. In some subjects who appear on clinical and even investigatory findings to have pulmonary atresia, necropsy reveals instead extreme pulmonary stenosis, but such an error is not very important or relevant. This discussion presents the spectrum of phenomena associated with the varied forms of the pulmonary circulation in pulmonary atresia illustrated by specific cases, without detailing complete experience of the various syndromes, as it is felt desirable that these syndromes should be placed in perspective to each other. The development of left ventricular failure secondary to excessive pulmonary flow in some infants with pulmonary atresia and ventricular septal defect will be described. Further, attention is drawn to the probable role of a small tricuspid orifice or actual tricuspid valve stenosis in determining the size of the right ventricular cavity in patients with pulmonary atresia with an intact ventricular septum. Pulmonary atresia is not rare. Keith, Rowe, and Vlad (1958) recorded that the incidence of pulmonary atresia was about 20 per cent in various necropsy series of the tetrad of Fallot, and referred to 46 reported cases of pulmonary atresia without ventricular septal defect proven by postmortem examination. Necropsy figures probably overestimate the incidence in the tetrad of Fallot, but the number of reported cases without ventricular septal defect is steadily rising. The atresia may be localized to the level of the pulmonary valve with or without the presence of fused but otherwise fairly normally formed cusps, or it may be more extensive representing the ultimate severity of the usual fairly diffuse right ventricular outflow obstruction of the tetrad of Fallot. As in incomplete forms of obstruction to outflow (pulmonary stenosis), an intact ventricular septum is usually associated with localized valvar obstruction. The 6 cases recorded by Allanby et al. (1950) provide an excellent illustration of the various types of obstruction seen. The physiological variations and clinical syndromes encountered with pulmonary atresia depend finally not on the anatomy of the atresia but on the presence or absence of a significant ventricular septal defect and on the amount and route of pulmonary flow.
Lymphomas in dogs a morphologic, immunologic, and clinical study

One hundred seventy‐six canine lymphomas were classified morphologically using four of the major human lymphoma classification schemes (Rappaport, Lukes‐Collins, Kiel, and the Working Formulation). All 176 dogs received the same chemotherapeutic protocol. Sixty‐two of these lymphomas had their immunophenotypes established by examination of cell surface markers by automated cytofluorography. Several different morphologic types of canine lymphoma were identified and these were comparable to morphologic categories in human classification schemes. Follicular and low grade lymphomas were rare. The two most common morphologic types were diffuse large cell (centroblastic) and immunoblastic. The Kiel classification appeared to be the most useful human scheme for classifying the canine lymphomas. Cytofluorographic analysis was generally straightforward, and 60 of the 62 lymphomas were placed into one of three immunophenotypic categories: 27 pan‐T(LQ1)+SIg+, 21 pan‐T(LQ1)−SIg+, and 12 pan‐T(LQ1)+SIg. Two of the lymphomas could not be characterized immunologically because a pre‐existing or reactive non‐neoplastic population of lymphocytes made interpretation of single cell suspension analysis difficult. The authors identified correlations between morphology and survival and disease‐free remission; dogs with high‐grade tumors generally survived the longest and had the longest remissions. No correlations were identified between high concentrations of serum lactate dehydrogenase, age, sex, or stage of disease, and morphology, immunophenotype, remission, or survival times. A significant correlation between clinical illness and survival time was documented. The median age of the dogs was nine years, no significant effect of sex on prevalence was observed, and some breeds were significantly overrepresented. Significant morphologic‐immunophenotypic correlations included shorter remission and survival times for T‐cell tumors than B‐cell tumors, and a highly significant correlation between the pan‐T(LQ1)+SIg− “T cell” phenotype and hypercalcemia.
Worker, workplace or families: What influences family focused practices in adult mental health?

UNLABELLED WHAT IS KNOWN ON THE SUBJECT? : Family focused practice leads to positive outcomes for parents and children. There are barriers and enablers for practitioners being family focused. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE? : Worker skill, knowledge and confidence about family work are the most important factors associated with family focused practices. WHAT ARE THE IMPLICATIONS FOR PRACTICE? : Mental health nurses require specific skill training in family focused practices, time to engage with clients on parenting issues and that there are adequate services to refer family members to. ABSTRACT Introduction Family focused practice is thought to lead to positive outcomes for all family members. However, there are multiple barriers and enablers in adult mental health services to practitioners undertaking these actions. Aim The aim of this study was to examine the relative importance of worker, workforce and family factors to predict family focused practices (FFPs) in adult mental health services. Method Three hundred and seven adult mental health workers completed a 45 items family focused practice measure of 16 family focused practices. Thesis It was found that worker skill and knowledge about family work and an ability to assess the degree of parental insight into the child's connections to other family members and the community were important predictors of FFP, along with the closely related-worker confidence. While aspects of the worker, workplace and family each contribute to FFPs, this study highlighted the importance of worker skill, knowledge and confidence as central issues for adult mental health workers. Implications for practice Study implications include the need for training in specific FFPs, the provision of time to engage with clients on parenting issues and the need 5 to ensure that there are adequate services for workers to refer family members to.
A five- to fifteen-year follow-up study of infantile psychosis. IV. Patterns of cognitive ability.

Sixty-three children with an unequivocal diagnosis of infantile psychosis who attended the Maudsley Hospital between 1950 and 1958 were individually matched for age, sex, IQ and year of attendance with a control group of clinic children with non-psychotic disorders. Both groups were re-examined in 1963–4 and given individual psychiatric, neurological, social and psychological assessments. At follow-up (mean age 15 years 7 months) the psychotic children showed low scores on tests of verbal ability and higher scores on performance tests. They showed a characteristic WISC subtest pattern of high scores on the Block Design, Object Assembly and Digit Span subtests combined with a very low score on Comprehension; this pattern was more marked among the children with a pronounced language retardation. Similar patterns of Wechsler Performance Scale scores have been found in deaf children with poor language and in children with developmental disorders of language. This was interpreted in terms of the hypothesis that infantile psychosis develops on the basis of a central disorder of language and of perception of sounds. The psychotic children as a group were inferior to the controls in terms of social competence. Among the psychotics the mean SQ was significantly lower than their Non-Verbal IQ, whereas, among the controls, the two scores were approximately the same.
Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) Processing Speed Scores as Measures of Noncredible Responding: The Third Generation of Embedded Performance Validity Indicators

Research suggests that select processing speed measures can also serve as embedded validity indicators (EVIs). The present study examined the diagnostic utility of Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) subtests as EVIs in a mixed clinical sample of 205 patients medically referred for neuropsychological assessment (53.3% female, mean age = 45.1). Classification accuracy was calculated against 3 composite measures of performance validity as criterion variables. A PSI ⩽79 produced a good combination of sensitivity (.23–.56) and specificity (.92–.98). A Coding scaled score ⩽5 resulted in good specificity (.94–1.00), but low and variable sensitivity (.04–.28). A Symbol Search scaled score ⩽6 achieved a good balance between sensitivity (.38–.64) and specificity (.88–.93). A Coding—Symbol Search scaled score difference ≥5 produced adequate specificity (.89–.91) but consistently low sensitivity (.08–.12). A 2-tailed cutoff on the Coding/Symbol Search raw score ratio (⩽1.41 or ≥3.57) produced acceptable specificity (.87–.93), but low sensitivity (.15–.24). Failing ≥2 of these EVIs produced variable specificity (.81–.93) and sensitivity (.31–.59). Failing ≥3 of these EVIs stabilized specificity (.89–.94) at a small cost to sensitivity (.23–.53). Results suggest that processing speed based EVIs have the potential to provide a cost-effective and expedient method for evaluating the validity of cognitive data. Given their generally low and variable sensitivity, however, they should not be used in isolation to determine the credibility of a given response set. They also produced unacceptably high rates of false positive errors in patients with moderate-to-severe head injury. Combining evidence from multiple EVIs has the potential to improve overall classification accuracy.
