LARGE EDDY SIMULATION OF FLOW OVER ELLIPTIC CYLINDER ARRAY IN SQUARE CONFIGURATION AT SUBCRITICAL REYNOLDS NUMBERS

Flow over arrays of cylinders of different cross-sections has been an essential area of research interest for a long time. For the estimation of flow characteristics around arrays of cylinders, numerical simulation of the flow past four elliptic cylinders in a square arrangement for a range of spacing ratios is analysed in this paper. Three spacing ratios considered in the present study are 3.45, 4.14 and 5.17. The results from the numerical simulation are compared with the experimental findings obtained previously using square cylinder arrays. The fluid flow modelling is performed by applying three-dimensional LES (Large-eddy simulation) with commercial software ANSYS Fluent 19R1. The results from the simulation for elliptic cylinder arrays involve both quantitative and qualitative analyses in the form of various patterns of flow, drag and lift coefficients, St (Strouhal number) and PSD (Power Spectral Density) plots. The Strouhal number values found for cylinder 1 and cylinder 2 in case of elliptic cylinder arrays are 0.642 and 0.703. It is observed that the force coefficients encountered by the cylinders are moderately varying for different spacing ratios.
First-Year Student Transition at the University of the Free State during Covidâ€‘19: Challenges and Insights

First-year seminars and university induction programmes are embedded with academic and social skillsrequired by students to transition into their first year of study. The first-year seminar at the Universityof the Free State is a credit-bearing module called UFS101, and is a prerequisite for degree completion.Students are assessed through summative assessment opportunities throughout the year. In 2020, theUFS101 module embarked on new territory by condensing the contact time for the first semester intoa week-long summer school. Furthermore, the summer school was presented a week prior to the start of university, with repeat sessions during the first week of class, and during the March holiday. However, due to national lockdown regulations as a result of Covidâ€‘19, a part of the cohort had to self-study the content via an interactive online study guide. This created four distinct groups of students: those who attended face-to-face classes, some face-to-face classes and some self-study, self-study only, and students who could not access the content. In order to measure their transition into university, a questionnaire was distributed to the students, and the results were stratified according to one of the aforementioned categories. Unique similarities and differences were observed in the findings. The results depict that effective content design is at the heartbeat of student transition, but that other factors such as face-to-face interaction with students, and access to resources assist with the transition into university. This study highlighted the need to explore the challenges students experience within their first six months at university, and substantiates that this type of exploration should be routinely conducted to assist with the understanding and implementation of first-year student support.
Corporate Social Responsibility And Brand Equity Of Malaysian Top 100 Brand Companies

In the recent economic systemic shifts perceived by the company value system from tangible to intangible assets, interest in brand equity receives growing attention from both practitioners and academics. Nevertheless, since most of these organisations accept these activities as part of their corporate social responsibility (CSR), corporations are also gradually implementing more ethical behaviours in relation to their communities. They are also acknowledging their crucial role in social, environmental and economic issues and the way in which they can enhance their companies’ brand equity. Having acknowledged the significance of CSR activities, the purpose of this paper is to provide a greater insight into how CSR practices affect company brand equity. Very few studies have examined this relationship in the context of Malaysian public listed companies (PLCs). Secondary data obtained through content analysis of Malaysian PLCs’ 2016 Annual Reports and a sample of Malaysia’s Top 100 Brands (whose names and brand equity values are set out on The Brand Finance website) was used to cover the assessment. The results showed that companies aggressively involved in CSR operations, especially environmental, community and workplace operations, found that this involvement enhanced their brand value. Reasonable CSR activities can effectively achieve high brand value. The findings are pertinent to both practice and theory.
Bioimage analysis of cell physiology of primary lens epithelial cells from diabetic and non-diabetic cataract patients

Abstract Cataract is a multifactorial disease with increasing prevalence with age. Adult diabetics develop cataract earlier. Lens epithelial cells (LECs) exposed to oxidative stress (ROS), increased calcium deposit and membrane damage, undergo apoptosis, which results in lens opacification. Remaining LECs post-surgery leads to posterior capsular opacification (PCO). This study’s aim was to investigate the physiological characteristics of LECs from cataractous diabetic and non-diabetic lenses. Leader cells migration from age-related cataracts started on day 5–7 and from type-2 diabetics on day 8–10. Differences were found in the collective migratory activity and colony formation. On day 22, the colonies formed by LECs from age-related cataracts were three times more, than those formed by diabetic LECs. DNA synthesis and FOXM1 expression occurred in 55.76% of age-related cataract LECs, but only in 33.45% of diabetic LECs. The highest level of reactive oxygen species (ROS) was found in diabetic LECs. Extracellular matrix calcification followed the same pattern as ROS. Among the main reasons for the development of age-related and diabetic cataracts is lens damage due to ROS release and elevated calcium levels. Diabetic LECs experience significantly lower in vitro migration and proliferative activities, compared to LECs from age-related cataracts. This is the first study of its kind in Bulgaria, contributing to the elucidation of the mechanisms of primary and secondary cataractogenesis in diabetic and non-diabetic adults.
A prospective study on awareness of postnatal mothers regarding self and newborn care in a tertiary care centre in Mangalore, Karnataka

Postnatal period begins after the third stage of labour and includes first six weeks after delivery. During this time women’s reproductive organs gradually return to the normal size and shape. Postnatal period is a crucial period in woman’s life as physiological changes occur. Women are in need of special care during pregnancy, at the time of labour as well as after delivery of child in order to have safe motherhood and healthy living. The postnatal period is a critical transitional time for a woman and her newborn physiologically, emotionally and socially. Postnatal care is one of the most important maternal health care for not only prevention of impairment and disabilities, but also for reduction of maternal mortality. Women should be advised of the signs and symptoms of potentially life-threatening conditions.

Testing Common Knowledge: Are Northern Europeans and Millennials More Concerned about the Environment?

This study explores whether there are differences in several environmental dimensions, when the European Region and Generation cohort are considered. In doing so, this study compares millennials in North and South Europe with members of Generation X in three environmental dimensions: attitudes, personal norms, and behavior. Using data from the European Social Survey (n = 6.216), the researchers tested the hypothesis that Northern Europeans and millennials have more pro-environmental standing than southerners and Generation Xers. The findings challenge the common belief that millennials are more committed to being environmentally conscious, showing that many millennials do not feel responsible for their climate footprint, nor do they behave in a way that shows more concern than previous generations to improve their environmental performance. Furthermore, contrary to expectations, Northern European participants are not the most committed, in all environmental dimensions, compared to Southern Europeans.
Influence of English Language on the Cultural Identity of Learners

The current research endeavored to find out the influence of English language learning on the Cultural Identity of Pakistani secondary school students. For purpose of investigation, 60 students of secondary level from private schools were selected for the data collection. A questionnaire consisting of close-ended questions was delivered to the participants to be filled in; the study had applied a quantitative method for data analysis. The result indicates that learning the English language has both positive and negative effects on student's Cultural Identity (CI). Learning the English Language is important, being the language of technology and lingua franca. But language never comes alone; it comes with its culture. The school students are getting affected by Western culture. This study has significant implications for further research work in this area.

Dynamic Deformation Behaviour of Chiral Auxetic Lattices at Low and High Strain-Rates

The mechanical behaviour of three different auxetic cellular structures, hexa-chiral 2D, tetra-chiral 2D and tetra-chiral 3D, was experimentally investigated in this study. The structures were produced with the powder bed fusion method (PBF) from an austenitic stainless steel alloy. The fundamental material mechanical properties of the sample structures were determined with classic quasi-static compressive tests, where the deformation process was captured by a high-resolution digital camera. The Split Hopkinson Pressure Bar (SHPB) apparatus was used for dynamic impact testing at two impact velocities to study the strain-rate dependency of the structures. Two synchronised high-speed cameras were used to observe the impact tests. The captured images from both quasi-static and dynamic experiments were processed using a custom digital image correlation (DIC) algorithm to evaluate the displacement/strain fields and the Poisson’s ratio. Predominant auxetic behaviour was observed in all three structures throughout most of the deformation process both under quasi-static and impact loading regimes. The tetra-chiral 2D structure showed the most significant auxetic behaviour. Significant stress enhancement in all tested structures was observed in dynamic testing. The Poisson’s ratio strain-rate dependency was confirmed for all three auxetic structures.

The finishing process using natural products has obtained satisfactory results with various tests for analyzing the properties of textiles after finishing. The critical analysis of this article has revealed that the textile finishing process using natural products seem to be economical, sustainable, have control over environmental and health hazard.
Root and Canal Morphology of Permanent Maxillary and Mandibular Incisor Teeth: A Systematic Review and Comparison with Saudi Arabian Population

Here we summarize the original studies and case reports addressing the root and root canal morphology of permanent anterior teeth among the Saudi Arabian population, comparing findings to the international literature. The maxillary and mandibular central and lateral incisors are among the most likely teeth to require endodontic treatments, so their morphology should be considered for root canal treatment success. All related literature published between 1980 and 2020 in peer-reviewed journals were included in this review. A systematic literature exploration was carried-out using the PubMed, ScienceDirect, Scopus, Evidence-Based Dentistry Journal, and Dental Practice databases. The search terms used were: “root canal morphology”, “root morphology”, “case report for anterior maxillary and mandibular teeth”, and “Saudi Arabian population”. Twenty-nine original research articles were identified. Most of the studies used the cone beam computed tomography (CBCT) technique. A total of 29 original research studies were included in this review. In the Saudi-based original research, three studies addressed mandibular and one study maxillary teeth and were conducted in various cities. Twenty-nine clinical case reports are presented: among these, three were Saudi patients. When comparing Saudi data to data gathered in other populations, the findings were mostly consistent in canal and root configuration of maxillary and mandibular anterior teeth. New devices and technologies are clinically useful in the identification of morphological variations in permanent teeth. Greater attention should be given to detecting additional canals. Variation among canals of mandibular anterior and maxillary teeth should be considered for successful endodontic treatment.
Fatal post-parturient diarrhoea in a nursing cow transported to Akinyele International Cattle Market, Ibadan, Nigeria: A case report

A pregnant cow of Kuri breed, estimated age of six years old with second calving was transported on land from Maiduguri, Borno state Nigeria. The journey took four days to the Akinyele International Cattle Market. The pregnant cow calved immediately on arrival at the market. A week after calving, the nursing cow was offered for sale and slaughter. The nursing cow and the calf were purchased and put under intensive medical and management care of an experienced cattle stockman in the market. The nursing cow became diarrheic on the second week of arrival at the market. Clinical examination by visual observation revealed projectile watery faeces, stained hindquarter and the pair rectal sterile swab samples were collected. Though the temperature and pulse rate were within the normal range. Standard bacteriological faecal culture of the rectal swab incubated overnight at 370C in selenith F- broth, Nutrient and blood agars at 370C for 24 hours were done, revealing heavy mixed growth of Escherichia coli, Klebsiella species and Bacillus species. Identification of colonies were based on morphology, gram staining, cultural and biochemical characteristics. In-vitro Antibiotic sensitivity testing on discrete colonies of bacteria faeces were done, using agar- Disk diffusion method. The E. coli, Klebsiella and Bacillus species were sensitive to ciprofloxacin® (10μg) and pefloxacin® (30μg). Sulfanol® (sulphadimidin) a broad spectrum antibiotic was administered immediately intramuscularly at 333mg in 3ml per 10kg for four days. Defaecation of the nursing cow stopped for two days after treatment. On the third day of the treatment, the faeces became pasty but the cow died overnight despite the good response to therapy.
Tobacco Smoking Among First Nations Youth Living On-Reserve and in Northern Communities: A Mixed Methods Study

The prevalence of tobacco smoking among First Nations youth living on reserve and in Northern communities is significantly higher than off-reserve Indigenous youth in Southern communities and non-Indigenous youth, although the majority do not smoke. Using a mixed-methods approach, we examine factors that support on-reserve First Nations youth’s resilience to smoking. Logistic regression analyses using data from the nationally representative First Nations Regional Early Childhood, Education, and Employment Survey suggest that not using other substances, having friends who do not smoke or use other substances, and having good mental health is associated with not smoking. A review of select community initiatives and in-depth interviews with First Nations anti-tobacco initiative managers and frontline workers about the initiatives also revealed the need for gender- and community-specific programming, recognition of Indigenous social determinants of health, and addressing the normalization of smoking in some community contexts.
Knowledge and attitude regarding organ donation among undergraduate medical students in a tertiary healthcare centre

Background: In India the rate of organ donation is less than 1 per million population. The need for organ transplantation is more than 5 lakhs per year. There is a wide discrepancy between demand and donation. Health care professionals can play a vital role in creating awareness in the society and encouraging the people to donate organs and thus help in filling the gap between the demand and donation. Aim of the study was to assess the knowledge and attitude regarding organ donation among medical students.Methods: A 24 item semi structured and self-administered questionnaire was used to assess the knowledge and attitude regarding organ donation from 300 undergraduate medical students in PGIMS, Rohtak. Data was collected, compiled and analyzed using SPSS.Results: The awareness regarding different organ donation was found to be kidney (79%), liver (70.7%), heart (61%), intestine (3.7%), and lung (10.3%). 28% participants were knowing about NOTTO (National organ and tissue transplant organization). 85% participants were willing to donate their organs.Conclusions: There is good knowledge and positive attitude towards organ donation among undergraduate medical students. But their attitude is not being transformed into organ donation. Separate chapters on organ donation and its need in our country should be included in the school curriculum, interactive sessions should be held in medical colleges and opportunities should be given to them during their college life to voluntarily donate their organs, only then we can cultivate their positive attitude and knowledge.
