Hall MHD simulations of collisionless multiple X line reconnection

[1] A Hall MHD simulation of multiple X line reconnection, in which a diffusion region around the standing X line and the moving plasmoids are involved, is presented. The observed features of Hall magnetic and electric fields in the diffusion region and the direction reversal of the electron flow in the vicinity of the magnetic separatrices are displayed in case 1 with the guide field By0 = 0. During the passage of a tailward moving plasmoid the bipolar By waveform signatures caused by the Hall current and the Hall electric field signatures in case 1 are qualitatively in line with the observations from the Geotail and Cluster spacecraft. Case 2 with By0 = 0.15 is carried out to investigate the reconnection configuration on the earthward side of the X line. The peaking signature of the positive By correlated with the bipolar (−/+) Bz is observed while an earthward moving plasmoid passes though the given point below the current sheet and close to the midplane; but the negative By is recorded at the given point above the current sheet. Such positive and negative By signatures, which are comparable with the observations from Cluster 3 and other Cluster spacecraft, are attributed to the By asymmetric structures associated with the Hall effect. The enhancement and variation of the electric field detected by Cluster 3 might be related to the −V′ × B electric field associated with the earthward movement of the X line.

Immunohistochemical Study of C-cells morphology, distribution and localization in the thyroid gland: A pilot study in cadaveric tissue

Objective: Exact identification of C-cells in thyroid with defined morphological features, number of cells present in whole population, ratio of parafollicular to follicular cells and localization is a challenge with conventional analysis. A specific and sensitive calcitonin immunohistochemistry is necessary for the demonstration. Method: Tissue obtained from 30 cadaveric specimens at AIIMS Jodhpur were processed, sectioned and stained for immunohistochemical analysis using calcitonin. The results obtained were also compared with H&E staining for same section. Results: C-cells were found distributed in both lateral lobes, concentrated around a vertical axis in cranio-caudal direction. It was a randomized distribution with hardly any symmetry. A complete homogeneous distribution of C-cells all over the thyroid was never demonstrated. C-cells were usually concentrated in the middle thirds of the thyroid, and more in the right lobe. Upper third predominantly had more C-cells as compared to lower third of the gland. Incidentally, no C-cells were found in the isthmus in any thyroid at all. When observed for the localization, most of the C-cells were in the interfollicular position. Conclusion: The present study findings corroborate the use of IHC for C-cell analysis in thyroid gland. Calcitonin proved to be an important diagnostic marker in C-cell identification. Quantification was done reliably, proving calcitonin used in the procedure justified due to its high specificity and affinity.
Semi-perimeter and inner site-perimeter of k-ary words and bargraphs

Given a bargraph B, a border cell of B is a cell of B that shares at least one common edge with an outside cell of B. Clearly, the inner site-perimeter of B is the number of border cells of B. A tangent cell of B is a cell of B which is not a border cell of B and shares at least one vertex with an outside cell of B. In this paper, we study the generating function for the number of k-ary words, represented as bargraphs, according to the number of horizontal steps, up steps, border cells and tangent cells. This allows us to express some cases via Chebyshev polynomials of the second kind. Moreover, we find an explicit formula for the number of bargraphs according to the number of horizontal steps, up steps, and tangent cells/inner site-perimeter. We also derive asymptotic estimates for the mean number of tangent cells/inner site-perimeter.
Native arteriovenous fistula, surgical outcomes and primary failure in Taiz Yemen: A prospective study

Background: Haemodialysis (HD) is a lifesaving and life-sustaining management for patients with End Stage Renal Disease (ESRD). There are number of vascular access options including native Arteriovenous Fistulas (AVF), artificial arteriovenous grafts (AVG) and dialysis catheters. AVF is generally recognized as the cornerstone of long-term dialysis treatment due to its superior patency and lower complication rates. The present study investigates surgical outcomes and complications post AVF creation by Parachute Vascular Anastomosis Technique (PVAT) in Taiz, Yemen. Materials and methods: This prospective study of 196 patients who underwent a native AVF created by parachute anastomosis technique from October 2017 to September 2019 in Authority of Althawra hospital in Taiz- Yemen. Detailed physical examination (inflow arterial pulses and outflow veins) was performed. Patients with abnormal physical examination were sending for preoperative sonography mapping. Non-dominant upper extremity was used as priority site for vascular access creation. AVF was performed under local anesthesia. Patients were followed up in outpatient clinic for six months. Result: Total of 231 AVF in 196 patients, 121 (61.7%) were male and 75 (38.3%) were female. Mean age was 48.5 ± 16.8 (range 9–85) years. A majority of AVF were brachiocephalic 112 (48.5%) while the remaining was radiocephalic 74 (32%) and brachiobasilic 43 (18.6%). Most of patients had left non-dominant upper arm AVF. The immediate patency rate (palpable thrill intra operative) was 218(94.4%) with an overall functional rate (successful use of the AVF for six consecutive sessions of HD) of 198 (85.7%). The primary failure rate (within 3 months) was 33 (14.3%). Six months primary patency was 186 (80%). During study period, the most common complication of AVF was thrombosis 30 (13%). Conclusion: Based in our result and literature review we could report excellent functional rate (85.7%) of AVF created by parachute vascular anastomosis technique. For that, parachute technique may be suggested as one of optimal selection to create AVF especially in elderly, diabetic patients.
A Speech Act Analysis of English Utterances of Two Chinese Children in a Multilingual Setting

A lot of scholarship on speech acts has focused on the implementation of speech actions by foreign learners (Bardovi-Harlig, 2001; Olshtain & Blum-Kulka, 1985; Yang, 2009). Most of these studies, however, adopt interview to conduct their study. This study explored 20 English utterances produced by two Chinese children in the Philippines, employing Speech Acts Theory of Austin and Searle. The results of the study concluded that illocutionary acts that are assertive, directive, commissive, expressive, and declarative were employed by both of the kids; there were some similarities and differences in the two kids’ speech acts; to some degree, speech acts can reflect the speaker’s characteristics. From the results, we can see that assertive, directive, commissive, expressive, and declarative are effective pragmatic strategies in communication for children. It is strongly recommended that we should do more research on English speech acts performance produced by Non-native English children living in a multilingual setting.
Board Gender Diversity and Corporate Expropriations: Evidence from Pakistan Stock Exchange

Sadaf Parveen, Hamid Ullah, Muhammad Kamran Khan, Shahid Jan Islamia College Peshawar, Pakistan, gulsadaf17@gmail.com Islamia College University, Peshawar, Pakistan, hamidullah@icp.edu. pk Bacha Khan University, Charsadda, Pakistan, drkamrankhan@bkuc.edu. pk Islamia College University, Peshawar, Pakistan ARTICLE DETAILS ABSTRACT History Revised format: February 2021 Available Online: March 2021 This research study investigates the role of board gender diversity in mitigating the risk of corporate expropriation of listed companies in Pakistan. For this purpose, data from 2009 to 2019 has been collected for 223 firms randomly selected from 24 non-financial sectors. The current study used panel data analysis techniques i.e. random vs fixed-effect regression models were estimated for testing the relationship of board gender diversity and corporate expropriations. The results of the panel data analysis showed that Hausman test results support the random effect models for the analysis of the data. The results of the random effect models showed that board gender diversity has a negative significant effect on the dividend ratios and director loans, which are used as a proxy for corporate expropriations. Moreover, external audit quality, growth, and leverage are also found to hurt corporate expropriations. However, managerial ownership, net profit margin, and size variables are found to have a positive effect on corporate expropriations. The results of the study will be helpful for the corporate managers and policy makers regarding the corporate governance and provide a deep insight in to the role of the gender in managing and aligning the benefits of the outsider shareholders by reducing the corporate expropriations of controlling large shareholders. The study is novel in its nature as being the first study that has been conducted in the context of Pakistan and has studied the role of gender in managing corporate expropriations.
Standard setting anchor statements: a double cross-over trial of two different methods

This article was migrated. The article was marked as recommended. Context: We challenge the philosophical acceptability of the Angoff method, and propose an alternative method of standard setting based on how important it is for candidates to know the material each test item assesses, and not how difficult it is for a subgroup of candidates to answer each item. Methods: The practicalities of an alternative method of standard setting are evaluated here, for the first time, with direct comparison to an Angoff method. To negate bias due to any leading effects, a prospective cross-over design was adopted involving two groups of judges (n=7 and n=8), both of which set the standards for the same two 100 item multiple choice question tests, by the two different methods. Results: Overall, we found that the two methods took a similar amount of time to complete. The alternative method produced a higher cut-score (by 12-14%), and had a higher degree of variability between judges’ cut-scores (by 5%). When using the alternative method, judges reported a small, but statistically significant, increase in their confidence to decide accurately the standard (by 3%). Conclusion: This is a new approach to standard setting where the quantitative differences are slight, but there are clear qualitative advantages associated with use of the alternative method.
Depression in children and adolescents in primary care

Depression is a commonly occurring illness in children and adolescents. Appropriate and timely care of these patients is essential in the primary care setting. A narrative review was undertaken for pediatric depression based on the AAP-approved guidelines, GLAD–PC, for the management of depression in the primary care setting. Emerging research regarding suicidality and social media was also reviewed. There are many tools to assist primary care in the assessment and management of adolescents and children with depression. The key components include: Assessment and Diagnosis, Initial Management (including safety planning), Treatment, and Ongoing Management. Comprehensive interviews with patients individually and with caregivers along with the use of tools are critical to the assessment process. Initial management after confirming the diagnosis of depression includes safety planning, psychoeducation and referral to peer support. Evidenced-based treatments for depression in children and adolescents include psychotherapy, antidepressants (SSRIs), and the combination of the two. Brief psychosocial interventions (BPI) have also been demonstrated to be efficacious when compared to CBT. Ongoing management is essential to reach or to maintain remission. Depression is common in the pediatric population and it is critical that primary care provide accessible and timely care to this population and their families.
Forecastability of Earnings Surprises

I investigate whether it is possible to profitably trade on predicted earnings surprises, forecasted using the Foster (1977) model. Unlike the extant literature, which documents a strong positive relation between actual earnings surprises and returns, I find that trading on predicted earnings surprises, generated by the Foster (1977) model, has earned a small negative, but statistically indistinguishable from zero, return. This result highlights the difficulty in forecasting earnings surprises.
Analysing self-regulated learning strategies of MOOC learners through self-reported data

Massive open online courses (MOOCs) require registered learners to be autonomous in their learning. Nevertheless, prior research studies showed that many learners lack the necessary self-regulated learning (SRL) skills to succeed in MOOCs. This research study aimed to gain insights into the relationships that exist between SRL and background information from MOOC learners. To this end, a series of three MOOCs on computer programming offered through edX were used to collect self-reported data from learners using an adaptation of the Motivated Strategies for Learning Questionnaire. Results show significant differences in general learning strategies and motivation by continent, prior computing experience and percentage of completed MOOCs. Men reported higher motivation than women, whereas pre-university learners needed further guidance to improve their learning strategies.
Lifestyle practices among hypertensive patients attending the Family Medicine Clinic in a tertiary hospital in Nigeria

Introduction: Hypertension is a major modifiable cause of cardiovascular disease affecting more than one billion people globally. Lifestyle modifications form the corner stone for the mitigation of identified risk factors and the prevention and control of hypertension. Some of these factors include cessation of cigarette smoking, weight reduction, increase in physical activity, moderation of dietary sodium and alcohol intake and following the DASH eating plan. They may also facilitate drug step-down and drug withdrawal in highly motivated individuals. The objective of this study was to determine the extent to which diagnosed hypertensive patients modify their lifestyle. Methods: This was a cross-sectional study among 230 patients with essential hypertension in the Family Medicine clinic in a tertiary hospital using a structured pretested questionnaire. Results: Most of the participants (149; 64.8%) were educated on lifestyle practices by health workers. Abstaining from tobacco products (230; 100%) and drinking alcohol (230; 100%) were the most used lifestyle practices. Dietary fruit consumption (93; 40.4%) and engagement in physical activity for thirty minutes per day (35; 15.2%) were the least used lifestyle practices. Conclusion: Health workers were the main source of education of the participants on lifestyle modification. Use of alcohol and consumption of tobacco products were not practiced by all the study participants. Dietary fruit consumption and engagement in physical activity were not popular lifestyle practices. It is recommended that primary care clinicians inquire about unhealthy lifestyles during clinical consultations as well as motivate hypertensive patients to adopt and adhere to appropriate lifestyle modifications.
A Study on Risk Factors for Malnutrition among Primary School Children in Karnataka, South India

Primary school age is a dynamic period of physical growth and mental development of the child. Research indicates that nutritional deficiencies and poor health in primary school age children are among the causes of low school enrolment, high absenteeism, early dropout, and poor classroom performance. The present situation with regard to the health and nutritional status of the children in our country is very unsatisfactory. Apart from mid-day meal program, which is run by the Government of India in government run schools, there are no other efforts for children in age group of 5–14 years. [1]
The Effect of Translation on the Approximated First Order Polarization Tensor of Sphere and Cube

Throughout this paper, the translation effect on the first order polarization tensor approximation for different type of objects will be highlighted. Numerical integration involving quadratic element as well as linear element for polarization tensor approximation will be presented. Here, we used different positions of an object of fixed size and conductivity when computing the first order polarization tensor. From the numerical results of computed first order polarization tensor, the convergence for every translation is observed. Moreover, discretization of the geometric objects into triangular meshes was done by using meshing software called NETGEN mesh generator while for the numerical computation, MATLAB software was used. We found that the translation has no effect on the approximated first order PT for sphere and cube after we have computed the first order PT for both geometries with a few center of masses. The numerical results of approximated first order polarization tensor is plotted by comparing the numerical results with analytical solution provided.
Hydrogen for heating? Decarbonization options for households in the United Kingdom in 2050

The heating sector makes up 10% of the United Kingdom’s carbon footprint, and residential homes account for a majority of demand. At present, central heating from a natural gas-fired boiler is the most common system in the UK, but low or zero-carbon hydrogen and renewable electricity are the two primary energy replacement options to reduce the carbon footprint. An important consideration is how using either energy source would affect heating costs. This assessment projects the costs for a typical single-family UK household and climate performance in 2050 using low-GHG or GHG-neutral hydrogen, renewable electricity, or a combination of both. The cost of using boilers or fuel cells in 2050 with two types of hydrogen are assessed: produced via steam-methane reforming (SMR) combined with carbon capture and storage (CCS), and electrolysis using zero-carbon renewable electricity. The costs of heat pumps, the most promising heating technology for the direct use of renewable electricity, are also assessed in two scenarios: a heat pump only and a hybrid heat pump with an auxiliary hydrogen boiler.You can download this document from the International Council On Clean Transportation website linked here

Association between Polycystic Ovary Syndrome and Breast Cancer: A Review

Aims: Polycystic ovary syndrome (PCOS) is a common endocrine disorder seen in women of reproductive age. The hormonal profile and comorbidities seen in women with PCOS like obesity and diabetes are some of the main risk factors of breast cancer. The aim of this review is to investigate the plausible association between PCOS and breast cancer. This review focuses on the epidemiological evidence, association of PCOS-related symptoms and PCOS medications on the incidence of breast cancer. Methodology: A comprehensive literature search using Ovid MEDLINE, Google Scholar and PubMed was performed to identify epidemiologic studies that have been published in the last 10 years (from 2010 to 25th June 2020) that reported on the association between PCOS and breast cancer. The following keywords were used: polycystic ovary syndrome, breast cancer and breast neoplasms. Results: Most of the epidemiological studies did not observe significant association between PCOS and breast cancer. However, evidence shows that elevated androgen levels and estrogen levels are associated with increased risk of estrogen receptor positive breast cancer. In addition, this review found increased breast cancer risk in women with obesity, hyperinsulinemia and low level of sex Review Article Kwan et al.; ARJGO, 4(4): 1-12, 2020; Article no.ARJGO. 62514 2 hormone binding globulin. Unlike metformin and clomiphene citrate, combined hormonal contraceptive, being the first line treatment for PCOS is linked with higher breast cancer risk. Conclusion: Clinical findings from this review are inconsistent, hence a firm conclusion cannot be made regarding the association between PCOS and breast cancer, emphasizing the need for more prospective studies to be conducted in the future.
