Large eddy simulation of a utility-scale horizontal axis turbine with woody debris accumulation under live bed conditions

Tidal and riverine flows are viable energy sources for consistent energy production. Installing and operating marine hydrokinetic (MHK) turbines requires assessing any potential impact of debris accumulation on turbine performance and sediment transport. More specifically, MHK devices may alter the natural sediment transport processes and cause debris accumulation, disrupting the natural sediment dynamic. In turn, these processes could affect the turbine’s performance. We carried out a series of large-eddy simulations coupled with bed morphodynamics, introducing various debris loads lodged on the upstream face of a utility-scale turbine tower. The objective is to systematically investigate the impact of debris accumulation on the performance and hydro-and morpho-dynamics interactions of the horizontal-axis MHK turbine under rigid and mobile bed conditions. To that end, we (1) employed the actuator line and surface methods for modeling turbine blades and the nacelle, respectively,(2) directly resolved individual logs, and (3) solved the Exner equation to obtain the instantaneous bed deformation of the mobile bed. Our analysis revealed that while the spinning rotor amplifies scour around the pile, debris accumulation modifies the sediment dynamics of the system. Also, it found that morphodynamic processes accelerate the wake recovery, slightly enhancing the turbine's performance.

Nonstop mutation in the kisspeptin 1 receptor (kiss1r) gene causes normosmic congenital hypogonadotropic hypogonadism

Purpose: Congenital hypogonadotropic hypogonadism (CHH) is a rare genetic disorder mostly characterized by gonadotropins release and/or action deficiencies. Both isolated (idiopathic hypogonadotropic hypogonadism) and syndromic (Kallmann) forms are identified depending on the olfactory ability. Clinical and genetic heterogeneities of CHH have been widely explored, thus improving our understanding of the disease's pathophysiology. This work aims to (1) provide a detailed clinical and hormonal description of normosmic CHH patients and (2) identify the mutation linked to the studied phenotype. Participants and methods: We investigated three affected patients with normosmic CHH, belonging to a consanguineous Tunisian family. Patients underwent an insulin-induced hypoglycemia test. We performed whole exome sequencing to identify the causal mutation. Results: At first diagnosis, a total gonadotropic deficiency was identified in all patients. The insulin-induced hypoglycemia test has also revealed a reduced cortisol secretion and complete growth hormone deficiency. At 20.8 years, one female exhibited a spontaneous recovery of the hypothalamic-pituitary-adrenal axis function, unlike her affected siblings who still depend on corticosteroid replacement therapy. Herein, we identified a novel homozygous nonstop mutation (c.1195T>C) in KISS1R gene in all affected subjects. This mutation led to the substitution of the physiologic stop codon by an arginine (p.X399R). Conclusions: Our study highlights the importance of the KISS1R signaling, in gonadotropin-releasing hormone neurons, in the control of reproductive function. Additionally, our data suggests a complex central and peripheral metabolic control of puberty, through the hypothalamic KISS1R signaling. We suggest a mutual link between the hypothalamic-pituitary-gonadal, -adrenal, and -somatotropic axes.

Assessment of current community pharmacist labeling practice: a simulated client approaches

The labeling of medications includes the provision of information and instructions as well as a unique identity for the medical product. It is one of the most important sources of information for patients. Good labeling practice is critical to ensuring patients' safe and effective use of products. Misreading the label, insufficient data on the label, inappropriate labeling font, writing style, and placement on the dosage form can all have disastrous consequences. The objective of this study was to assess medication labeling practices among community pharmacists in Libya. A simulated client method (SCM) was used, and the study was carried out in the City of Zawia, where 146 local pharmacies were visited over three months for the investigation (January to March 2023). These visits were made at random, without the pharmacist's knowledge. The findings revealed that all dispensed drugs were not labeled, and none of the practicing pharmacists in any pharmacies visited displayed any drug label, printed or handwritten. The majority of pharmacists did not address or explain significant information to the patient in an effective manner, which led to inappropriate and harmful consumption of medications. The absence of dispensed drug labels reduces the patient's knowledge of the necessary information about the medicine, resulting in a treatment deficit or unsuccessful therapy. Thus, more effort should be made by health authorities to instruct pharmacists to use and work according to international labeling standards or to establish local labeling specifications.

A systematic review on self-reported questionnaires to assess medication adherence in diabetic patients

Adherence to pharmacological therapies are keys to effective treatments in diabetic patients. Previous reviews found that most adherence measurement studies on chronic diseases used a self-reported scale. However, there is no consensus on the best scale to measure adherence in diabetic patients. The purpose of this systematic review was to identify the potential self-reported scale that could be considered for measuring medication adherence in diabetic patients and to provide recommendations for researchers or clinicians to determine appropriate adherence self-reported scales in diabetic patients. This review follows general guidelines in the implementation of systematic reviews. After further review, it was found that 33 studies met all inclusion criteria from 4 databases (Wiley, Science Direct, Scopus, and PubMed). The articles were done by the PRISMA, while the keywords were determined by the PICO method. Most research was conducted in Asia (69.7%) and America (18.2%) on patients with type 2 diabetes (81.3%), patients in hospitals (54.5%), suffering for 1–6 months (54.5%), and using a cross-sectional study design (78.8%). HbA1c clinic data (57.6%) were used in most studies as biological markers of adherence. The measurement scales of medication adherence in diabetic patients are MMAS-8 (57,.5%), MMAS-4 (12.1%), BMQ (9%), MCQ (6%), ARMS (3%), ARMS-D (3%), GMAS (3%), LMAS-14 (3%), and MARS-5 (3%). This review provides information on the different self-reported scales most widely used in diabetic medication adherence research. Various aspects need to be considered before choosing the scale of adherence.

Clinico-histopathological correlation in hansen’s disease: a retrospective study

Abstract Background: Hansen’s disease is a chronic infectious disease with a wide range of clinical manifestations. The clinical diagnosis must be confirmed by histopathological and bacteriological studies in order to adequately manage the condition and prevent drug resistance. Aim: To perform a clinico-histopathological correlation of skin lesions in all patients with a clinical suspicion of Hansen’s disease. Materials and methods: A retrospective, hospital based, cross-sectional study was conducted in the Department of Pathology, Father Muller Medical College, Mangalore. Skin biopsies of all suspected cases of Hansen’s disease received over a period of three and a half years were included in the study. Haematoxylin and eosin, Fite-Faraco stained sections of all cases were reviewed. The cases were classified according to Ridley–Jopling classification into TT, BT, BB, I, BL, and LL. Clinical details of the patient, including type and site of lesion were obtained from the patient’s medical records. Clinico-histopathological correlation was done for all the cases. In addition, wherever available, the corresponding slit-skin smears were also included. Results: A total of 76 cases were clinically diagnosed as Hansen’s disease. Clinico- histopathological correlation was seen in 33/76 cases (43.42%). The most common histological subtype of Hansen’s was Borderline Tuberculoid (BT) - 24/76 cases (31.58%). Maximum agreement was seen in Mid-borderline leprosy (92.11%). Fite Faraco stain was positive in 21 out of 76 cases. Slit skin smears were available for 55 cases and positive in 20 cases. Conclusion: Due to clinical and morphological overlap, it is imperative to correlate the clinical, histopathological and bacteriological index results in order to accurately subtype the categories in Hansen’s disease.

Online medical education in india – different challenges and probable solutions in the age of covid-19

Introduction: During the COVID-19 pandemic, most educational institutions have opted for online education rather than traditional modes of education to protect their employees and students. Online education has been gaining momentum in almost all countries around the world. This coincides with the recently introduced competency-based medical education in India which has embraced online education. This poses a new challenge for the institutions involved, the instructors or teachers, and the students since they must adapt quickly to the new mode of learning. Online education requires teachers to improve their competency in three major areas; pedagogy, technology, and content knowledge. Some of the challenges include; lack of technological skill, poor time management and lack of infrastructure. As technology rapidly advances, health care education systems must also advance in tandem. To implement the new competency-based system and online education, the institutions and the individuals must realize the importance of online education, identify the barriers and quickly work on solutions for success. Methods: This review was conducted based on various research papers on the topic of online medical education, the challenges faced by faculty members, and the opinion of students on this dilemma. Search terms included online medical education, COVID19, competency-based medical education. Conclusion: This review identified various challenges posed by online education on the current medical curriculum, faced by both faculty members and students, especially under the light of the Competency-Based Undergraduate Curriculum for Indian Graduates. Different solutions were proposed to overcome these challenges.

Effect of national crisis on mental health and academic performance of pharmacy students at attahadi university

Among the consequences of armed conflict, the effect on the mental health of the civilian population is one of the most significant aspect of psychiatric disorders. Studies of the general population show a positive increase in the incidence and prevalence of mental disorders. This study is aimed to determine the relationship of the national crisis on the mental health conditions of university students and their academic performance. Specifically, this study was aimed to evaluate the national crisis effects on the mental health and the academic performance as well as the association of the national crisis, mental health and academic performance. 40 sample size of pharmacy students at the academic year 2019-2020 at Attahadi University, Tripoli, Libya were used in this study and a survey of validated questionare for mental health was considered. The findings revealed that the effects of national crisis on the mental health of the students disclosed the verbal interpretation of rarely grade. Indeed it can be found that mental health of the students was not of greatly affected in this sample. The academic performance of the students disclosed that academic year levels one and three have verbal interpretation of good and academic year level two has fair. Though the academic performance of the students did not show a verbal interpretation of weak or very weak. It is still worthwhile to note that none of them has reached the very good and the excellent performance. It can be concluded that a need for the students coping strategies be enhanced for them to reach their maximum potential with their academic performance. This study shows also that a weak positive relationship among the variables. Though it’s not that high, indeed, the mental health of the students can be a predictor to their academic performance.

Traditional health practices concerning pregnancy, bırth, and the postpartum period of women giving birth in the hospital

Objective: This study was conducted to investigate traditional beliefs and practices of women regarding care of the mother and the infant during pregnancy, in childbirth, and in the postpartum period. Methods: This was a descriptive, cross-sectional study conducted at a public hospital in Istanbul. The data collected consisted of socio-demographic and obstetric characteristics, and responses to questions about some traditional customs regarding pregnancy, delivery, and the postpartum period. Results: In our research, some non-harmful cultural practices were found, such as the belief that to have a clever and beautiful baby the mother should eat fruit; that to have a healthy and peaceful pregnancy, the mother should not look upon ugly things; the mother should indulge her food cravings; and to have an easy birth, the mother should walk and focus on prayers. On the other hand, we also found beliefs that could be harmful, such as wiping the mouth of a baby with a date before breastfeeding, and practices believed to be protective that could cause harm, such as putting a knife under the baby’s bed, fastening a safety pin to the baby’s clothes, and for the mother and child to remain at home for 40 days. Conclusion: While non-harmful and beneficial practices related to maternal and infant health should be accepted and supported as a part of our cultural richness, practices that could be harmful should be prevented in pregnancy classes or with training upon hospital discharge

Investigating students’ attitudes toward poverty and impoverished persons - a case study: ho chi minh city open university, data of vietnam

Efforts to understand the causes of poverty, how poverty is perceived have become important in the fight to mitigate poverty. In Vietnam, studies on the attitudes of poverty in specific populations, such as Vietnamese students, are rare. Thus, this dataset reports the results collected from 180 social work students and non-social work students of Ho Chi Minh City Open University through attitudes toward poverty and poor people in Vietnam. The Attitude toward Poverty Short Form 21-item scale, developed by Yun & Weaver, was used for the data collection. The survey results showed that when looking for causes of poverty, social work students and non-social work students put the most emphasis on structural factors of poverty. However, social work students, compared with non-social work students, consider personal deficiency and stigma more important. In future, this dataset can serve as a reference source for comparative studies on student’ attitudes toward poverty and impoverished persons and for social work education.

Variation diachronique complexe des formes du présent de l’indicatif du français

Étudier les phénomènes grammaticaux actuels sans s’interroger sur la longue trajectoire historique qui a servi de support et de canal au français moderne manquerait de pertinence. En effet, une telle étude permet une meilleure compréhension des phénomènes linguistiques contemporains. Ainsi, notre domaine de recherche, la linguistique diachronique, met l’accent sur les connaissances étymologiques de la langue. Il s’agira, pour les besoins de l’article, de rendre compte de l’évolution morphologique du présent de l’indicatif depuis le latin jusqu’au français moderne. Notre curiosité nous poussera à nous interroger sur les raisons qui expliquent l’écart morphologique du présent de l’indicatif entre le latin et le français moderne. En sus, l’étude des variations diachroniques du présent de l’indicatif renseigne sur les formes actuelles de ce temps verbal. Du latin au français moderne, le présent de l’indicatif subit des flottements aussi bien dans ses radicaux que dans ses désinences. Ceci met en chef l’écart formel existant entre le présent latin et celui du français actuel. Toutefois, les phonèmes subirent des transformations selon qu’ils étaient toniques ou atones, radicaux ou désinentiels. Certaines formes se sont maintenues avec modification ou non de sons; d’autres ont complètement disparues du système. Suivant un ordre chronologique et des lois phonétiques cohérentes, nous montrerons que les formes actuelles du temps le plus usuel du système, le présent, ne sont pas le fruit du hasard. De ce fait, la langue moderne gagnerait à revisiter la morphologie des temps verbaux depuis leur origine pour mieux asseoir les difficultés liées à la conjugaison et fournir une explication authentique sur les variations de forme jusque-là ignorées par certains.

Finance for decision makers

In their different ownership structures, business enterprises pursue different strategies towards accomplishing their owners’ needs and interests. At the heart of these accomplishments is the generation of sufficient financial returns to cover obligations as they become due and residual incomes for the owners. It is doubtless that without a grip of financial stability, the survivability of for-profit organizations becomes bleak. Financial management plays and instrumental role in this case. The generation of sufficient information for decision making for the business and investors alike is integrally critical in shaping the progression of the business enterprise. While businesses provide financial statements according to prevailing laws and accounting standards to the public for their consumption in decision making, they are further needed to be accountable to them regarding their performance and investors’ engagements, especially considering that investors are foundational sources of capital for organizational operations.

Prevalence of gastrointestinal helminth parasites of local chicken slaughtered at jalingo market, taraba state, nigeria

Gastrointestinal parasites constitute a serious problem to poultry production in Africa. But often times they are usually ignored by the majority of farmers. Whereas, it is one of the major leading causes of ill-health and high mortality rates in the poultry industry. This study was conducted to determine the prevalence of gastrointestinal parasites of chicken slaughtered at the Jalingo market. A total of 500 gastrointestinal tracts of local chicken comprising of 250 from males and 250 from females were collected from the poultry slaughtering and dressing section of the Jalingo market, and screened for gastrointestinal helminths using the saturated sodium chloride floatation techniques. An overall prevalence of 28.6% (143/500) was recorded with a prevalence of 16.8% (84/500) in males and 11.8% (59/500) females. Nine different species parasites comprising five nematodes and four cestodes, were recorded. Nematodes were the most predominant intestinal parasite with a prevalence rate of 89 (62.2%). And Ascaridia galli 45 (50.5%) was found to be the most prevalent nematode. Other nematodes observed were Capillaria annulata 13.4% (12/89), Heterakis gallinarum 2.2% (2/89), Strongyloides avium 32.5% (29/89), and Syngamus trachea 1.1% (1/89) having the lowest prevalence. Railliatina tetragona 57.4% (31/143) was the most prevalent cestode recorded. Other Cestodes were Hymenolepis carioca 27.7% (15/54), Raillietina cesticellus 12.9% (7/54), and Davainea proglottina 1.8% (1/54). No trematode was recorded in this study. This study showed that nematodes and cestodes were the common helminth parasites in local chicken. There is therefore the need for educating the farmers on the impact of gastrointestinal parasite infection in chicken and the need to institute good management practices so as to reduce their effects on productivity. Sex of the chicken had no statistically significant difference (X2 = 6.12, df = 1; P > 0.05) on the prevalence of helminths.

The impact of turbulence and phytoplankton dynamics on foam formation, seawater viscosity and chlorophyll concentration in the eastern english channel

The space-time dynamics of chlorophyll a concentration and seawater excess viscosity has been investigated in the hydrographically contrasting inshore and offshore water masses of the eastern English Channel. This was done during the phytoplankton spring bloom dominated by Phaeocystis globosa before and after the very large-scale formation of foam induced by an increase in wind-driven turbulence and the related wave breakings. The results suggest that the dynamics of chlorophyll a concentration and seawater excess viscosity are differentially controlled by the formation of foam through the intensity of the spring bloom and wind-generated turbulence.
