Effects of Cow Horn Particulates as Addictive on Microstructure, Tensile and Compressive Properties of Recycled Aluminium Alloy

In the recent time, the development of low cost metal alloys reinforced with waste materials such as agricultural waste and industrial waste has been one of the major innovations in the area of material science. Aluminium scraps were used as raw material and reinforced with locally available inexpensive cow horn particulate (CHp) of 3, 6, 9 and 12% by weight to develop a new material in the present study. The microstructure view was studied using optical microscope for analysing the distribution of CHp. The tensile and compressive strengths were studied for the reinforced CHp aluminium alloy. The results revealed that the tensile and compressive strengths values increase as the CHp increases and falls when the weight proportion reaches 12% due to poor wettability. Increment of 10.1%, 19.2%, 29.4% and 8.7% in tensile strength and 13.3%, 31.2%, 43.2% and 12.7% in the compressive strength were recorded for addition of 3%, 6%, 9% and 12% CHp reinforcement, respectively. The microstructure examination shows that the control sample contained fine, packed and shining grained structure while the CHp reinforced aluminium alloy contained less packed, dull with some inclusion grained structure. The inclusion and dull surface of the grains was observed increases as the percentages of the cow horn particles added increased. The spectrographic analysis conducted to determine the chemical compositions of all the specimens, showed various elements present in control sample and CHp reinforced aluminium alloy. Aluminium is in the range 91.3-93.0%, followed by silicon with 4.36-5.01%, other elements present include iron, copper, magnesium, manganese, chromium, nickel, zinc, titanium, lead, and others.
Effects of Low-Intensity Vestibular Noise Stimulation on Postural Instability in Patients with Parkinson's Disease.

BACKGROUND Postural instability is a major disabling factor in patients with advanced Parkinson's disease (PD) and often resistant to treatment. Previous studies indicated that imbalance in PD may be reduced by low-intensity noisy galvanic vestibular stimulation (nGVS). OBJECTIVE To investigate the potential mode of action of this therapeutic effect. In particular, we examined whether nGVS-induced reductions of body sway in PD are compatible with stochastic resonance (SR), a mechanism by which weak sensory noise stimulation can paradoxically enhance sensory information transfer. METHODS Effects of nGVS of varying intensities (0-0.7 mA) on body sway were examined in 15 patients with PD standing with eye closed on a posturographic force plate. We assumed a bell-shaped response curve with maximal reductions of sway at intermediate nGVS intensities to be indicative of SR. An established SR-curve model was fitted on individual patient outcomes and three experienced human raters had to judge whether responses to nGVS were consistent with the exhibition of SR. RESULTS nGVS-induced reductions of body sway compatible with SR were found in 10 patients (67%) with optimal improvements of 23±13% . In 7 patients (47% ), nGVS-induced sway reductions exceeded the minimally important clinical difference (optimal improvement: 30±10% ), indicative of strong SR. This beneficial effect was more likely in patients with advanced PD (R = 0.45; p = 0.045). CONCLUSIONS At least half of the assessed patients showed robust improvements in postural balance compatible with SR when treated with low-intensity nGVS. In particular, patients with more advanced disease stages and imbalance may benefit from the non-invasive and well-tolerated treatment with nGVS.
The Effectiveness of CFRP- and Auxetic Fabric-Strengthened Brick Masonry under Axial Compression: A Numerical Investigation

Bonded brickwork used for loadbearing walls is widely found in heritage structures worldwide. The evaluation of bonded masonry structures and their strengthening strategies against dynamic actions require appropriate understanding under cyclic loading. Subsequently, a simplified 3D microscale numerical model is developed in this paper to analyse bonded brickwork under cyclic compression. A plasticity-based damage constitutive model to represent damage in masonry bricks under cyclic compression loading was employed, and zero-thickness interfaces were considered with non-linear damage properties to simulate the mechanical behaviour of masonry. A threshold strain level was used to enact the element deletion technique for initiating brittle crack opening in the masonry units. The developed model was validated against the experimental results published by the authors in the past. The models were able to accurately predict the experimental results with an error limit of 10% maximum. Mainly, two types of strengthening materials, possessing (1) high energy absorption characteristics (auxetic fabric) and (2) high strength properties (carbon fibre reinforced polymer composites/CFRP) were employed for damage mitigation under cyclic compression. Results show that the CFRP-strengthened masonry failure was mainly attributed to de-bonding of the CFRP and crushing under compression. However, the auxetic strengthening is shown to significantly minimise the de-bonding phenomenon. Enhanced energy dissipation characteristics with relatively higher ductility (up to ~50%) and reduced damages on the bonded brickwork were observed as compared to the CFRP-strengthened brickwork under cyclic compression loading. Additionally, the auxetic fabric application also increased the compressive resistance of brickwork by 38–60% under monotonic loading, which is comparably higher than with the CFRP strengthening technique.
Assessment of the nutritional status and dietary intake of women of childbearing age in the city of Comè, Benin

Introduction over nutrition and undernutrition problems affect many women of childbearing age in Benin. The inadequacy of the diet is the major reason. The objective of this study is to assess their nutritional status and diet in Comè, a city with the highest proportions of adverse neonatal outcomes in the Mono regional department of Benin in 2015. Methods data were collected in June 2017 in a cross-sectional survey with a two-stage random sampling of non-pregnant or lactating women aged 15-49 years. Their sociodemographic characteristics, diet and nutritional status were reported and explored through descriptive and bivariate analysis. Results the prevalence of underweight was 9.5% and overweight (overweight and obese) was 31.7%. The dietary diversity score was low for 47.9% of them. Compared to the Recommended Dietary Allowances, the energy and protein intakes were insufficient for 78.7% and 11.8% respectively. None of them had an energy-balanced diet according to the energy distribution between macronutrients after normalization of intakes. The contribution of carbohydrates was high in 99.1%, low in 96.2% for fats and adequate in 60.2% for proteins. Conclusion these results reiterate the importance of developing nutritional interventions to improve the nutritional status and the diet of women of childbearing age in Benin. Periodically national food surveys must be conducted to evaluate their real nutritional intakes and promote better nutrition.
Burnout and Online Medical Education: Romanian Students in Lockdown and Their Residency Choices

The primary aim of the study was to investigate the prevalence of burnout in Romanian medical students during the COVID-19 pandemic using the Maslach Burnout Inventory-General Survey for Students (MBI-GS(S)). The presence of burnout was assessed based on Exhaustion (EX), Cynicism (CY) and Professional Efficacy (PE) subscales. The secondary aim of the study was to identify the presence of intentional shift in medical specialty compared to their initial pursued choice within the population investigated. Data was collected online at the end of 2020 and beginning of 2021 through a licensed, customized MBI-GS(S) questionnaire from a sample of 126 Romanian medical students at the two leading medical schools in the country, Iasi (N = 56) and Cluj Napoca (N = 70). Descriptive statistics and bivariate correlations were also applied to describe the data set (age and gender of participants) and the relationship between variables (EX, CY, PE). Subsequently, the MBI-GS(S) group report revealed that 36.5% of the medical students in the sample (46) experienced burnout, with problematic results both in Exhaustion and Cynicism. Exhaustion and Cynicism, which contribute to burnout, showed high scores compared to the average scale (EX = 3.5/2.4; CY = 2.8/1.8), while the Professional Efficacy score was relatively high (PE = 3.8/4.4), showing a protective effect and burnout reduction. One of the main conclusions is that the consequences of burnout in medical students plays a significant role in shaping the future healthcare practitioners’ perception of the medical profession and of patients’ wellbeing. Exhaustion and Cynicism are mainly associated with depersonalization and disconnection from the patient. Another conclusion of the study is that about one third of the respondents (30% Cluj students and 37.5% Iasi students) considered changing residency options. The pandemic has also revealed the limitations of and challenges facing current medical education, and that further research is required to assess the trends in prevalence of burnout in medical students.
Bypassing Confines of Feature Extraction in Brain Tumor Retrieval via MR Images by CBIR

To check out the health of the patient, digital images are generated every single day and are used by the radiologist for extracting out the details and anomalies. The complicated part is to figure out the disease in those images. By the manual diagnosis of the images through the radiologists, the doctors can get to know exact scenario of the abnormalities in images, but is considerably more difficult with Content Based Image Retrieval (CBIR) to get those finer details from MR images. These CBIR approaches are now frequently employed in the automatic diagnosis of disease from MR images, mammograms, and other sources. Bridging this gap can be done with deep learning feature extraction algorithm and the canny edge detection technique we propose, and accuracy closer to the manual results of a human evaluator can be achieved to a significant extent as part of the goal of sustainable development through innovation.
Waiting Time of Patients in Outpatient Hospital Before and After Pandemic Covid 19: A Literature Review

Patient waiting times is an important factor that affecting hospital services quality. Waiting time will affect service satisfaction and repeat visits at the hospital, especially for outpatients. This study aims to determine the literature review of the patient waiting time at the hospital. Method: The literature review method with the PRISMA approach used in this literature review. Synthesis of data used the PICO method. The articles source was through Google Scholar, Pubmed NCBI and DOAJ. The inclusion criteria set were articles with the keywords "factor, waiting time, outpatients, hospitals", articles in Indonesian or English, published in 2012-2022, and accessible in full text. Results: In this literature, 10 articles were found that matched the inclusion and exclusion criteria. A total of 4 articles were obtained after the Covid 19 pandemic and 6 articles before the covid 19 pandemic. Before the covid 19 pandemic, the average waiting time for 6 articles was 83.62 minutes with the fastest time of 65 minutes and the longest time of 149 minutes. After the COVID-19 pandemic, the average waiting time for 4 articles was 42.6 minutes with the fastest waiting time of 19.2 minutes and the longest waiting time of 93 minutes. This shows that the waiting time is faster during the pandemic than before the pandemic. In the results, the factors that influence the waiting time before the pandemic are human resources and medical records. One article states that the waiting time factor is the type of hospital and gender. After the pandemic, the influencing factors were found: arrival time, number of patients, registration time, medical records and medical records. Conclusion: the addition of hospital staff and an electronic-based medical record system can be an effort that can be made to shorten waiting times. However, if this is not possible, information on the order and time of service to patients can be an alternative to reduce waiting times
Overview of the Effect of Different Regenerative Materials in Class II Furcation Defects in Periodontal Patients

The aim of this review was to give an overview of the outcomes of the use of different regenerative materials to treat molars with class II furcation defects in patients with periodontitis in comparison with open flap debridement (OFD). A search of five databases (PubMed-Medline, Embase, Cochrane, Scopus and Web of Science) was conducted up to and including January 2022. According to the PICOS guidelines, only randomized control trials (S) considering periodontal patients with at least one molar with a class II furcation involvement (P) treated with regenerative materials (I) in comparison to OFD as control treatment (C) and a minimum follow-up period of 6 months were included. Vertical clinical attachment level (VCAL) was considered as the primary outcome (O), while horizontal clinical attachment level (HCAL), horizontal probing depth (HPD) and vertical probing depth (VPD) were considered as secondary outcomes. The search through the databases initially identified 1315 articles. Only 25 of them met the eligibility criteria and were included. The studies were grouped in four macro-categories according to the material used: absorbable and non-absorbable membranes, blood derivatives and a combination of different materials. The greater part of the included studies reported a statistically significant difference in using regenerative materials when compared to OFD. The blood derivatives groups reported a range of mean changes in VCAL of 0.86–4.6 mm, absorbable membrane groups reported −0.6–3.75 mm, non-absorbable membranes groups reported −2.47–4.1 mm, multiple materials groups reported −1.5–4.87 mm and enamel matrix derivatives reported a mean change in VCAL of 1.45 mm. OFD showed a range of mean VCAL changes of −1.86–2.81 mm. Although no statistical analysis was performed, the use of regenerative materials may be considered moderately beneficial in the treatment of molars with grade II furcation involvement. However, the substantial heterogeneity in the protocols’ design does not allow us to draw definitive conclusions. In addition, low levels of evidence for morbidity and patient-centered outcomes were reported.
Exploring the Five-Factor Structure of the Need for Closure Scale on Indian Samples Using Exploratory and Confirmatory Factor Analysis

This study was conducted to explore the five-factor structure of the Need for Closure scale on Indian samples using exploratory and confirmatory factor analysis. Data were initially collected from 450 samples which were reduced to 235 cases later based on the lie score criteria of the Need for Closure Scale. To rule out the problems caused by all questionnaire items like low reliability and low communalities, parceling of the items (creating three parcels from each facet) was done before the multivariate analysis (EFA and CFA). In the results, EFA showed that the five-factor structure of the NFC scale explains 52% of the variance. The goodness of fit statistics in the CFA model met the criteria (χ2 = 190.153, GFI = 0.908, TLI = 0.855, CFI = 0.890, RMSEA = 0.077) for the reasonable fit of the single factor structure of the NFC construct. In conclusion, this study presented the good psychometric properties of the NFC scale. It can be used to assess the individual's need for closure in the wider contexts of Indian studies.
Comparison of Short- and Long-term Outcomes
of Laparoscopic and Open Right Hemicolectomy
for Colon Cancer

Introduction: Colorectal cancer is still among the most common malignancies in the world. Aim: The aim of this study is to compare the outcomes of open and laparoscopic right hemicolectomy for colon cancer. Materials and methods: This retrospective study included 87 patients who underwent laparoscopic and open right hemicolectomy for colon cancer between January 2014 and January 2020. Patients were categorized into two groups according to the surgical technique: laparoscopic (46 cases) and open (41 cases). Patient characteristics and clinicopathological findings, surgical findings, short- and long-term results were included in the evaluation parameters. Patients with pathological diagnosis other than adenocarcinoma, distant metastases, and incomplete file datas were excluded from the study. Results: Forty-six (52.9%) patients underwent laparoscopic and 41 (47.1%) patients underwent open right hemicolectomy. The operation time of the laparoscopic group was found to be significantly higher (P<0.001). The amount of blood loss was significantly higher in the open group (P < 0.001). The incidence of post-operative complications in the open group (26.8%) was higher than in the laparoscopic group (6.5%) (P = 0.010). The rate of anastomotic leakage (9.8%) was higher in patients who underwent open surgery compared to laparoscopic group (0%) (P = 0.045). It was found that the laparoscopic group had a shorter hospital stay (P = 0.009). No statistically significant differences were found between the groups in terms of overall overall survival (OS) rate (P = 0.400) and disease-free survival (DFS) rate (P = 0.781). Conclusion: Laparoscopic right hemicolectomy for colon cancer is a feasible and reliable method with lower postoperative morbidity and similar long-term results to the open method.
Predicting Emotional-Social Competence Based on Academic Engagement, Self-efficacy and Perception of School Climate in High School Students

: The aim of this study was to predict emotional-social competence based on academic conflict, self-efficacy and perception of school climate in high school students in Minab. The research method was correlational, and regression was used to test the research hypotheses. The statistical population consisted of the second-high school students of Minab city from whom 380 people (200 male students and 180 female students) were selected as the study sample by stratified random sampling method. Four questionnaires including Social Emotional Competence, Academic Conflict, Academic Self-efficacy and Perception of School Atmosphere were used to collect data. The results showed that the predictor variables explained about 39% of the variance of the criterion variable. According to the findings, academic engagement (β = 0.224, P = 0.001) significantly predicted socio-emotional competence, which means that as students' academic engagement increases, their socio-emotional competence increases. Also, academic self-efficacy (β = 0.436, P = 0.001) positively and significantly predicted emotional-social competence, which means that with increasing students' academic self-efficacy, their socio-emotional competence also increases. Likewise, perception of school climate (β = 0.193, P = 0.001) positively and significantly predicted emotional-social competence, which means that with increasing perception of school atmosphere, students' emotional-social competence increases. According to the results, academic self-efficacy with a standardized coefficient (β = 0.436) compared to other predictor variables was a stronger predictor of students' emotional-social competence. In general, the research findings support the role of motivational and cognitive variables in students' emotional-social competencies.
Physico-chemical parameters and sensory attributes of different chicken meat of consumer’s choice from poultry market

Generally, consumers prefer the indigenous chicken meat compare to commercial chicken like sonali or broiler chicken because of their concept of having more nutritious and palatability and ready to pay more. Whether the concept is true or not, and on which aspects, indigenous chicken meat is superior compare to that of commercially reared chicken, validation is required. Therefore, an experiment was conducted to compare the carcass characteristics, meat proximate composition, physico-chemical parameters and sensory attributes of indigenous/deshi, sonali and broiler chicken that are available in the poultry market of Bangladesh. Three types of finisher chicken: indigenous/deshi, sonali and broiler chicken were bought from local market of Bangladesh. Birds were slaughtered following halal method; carcass traits and meat quality parameters were analyzed after collection and processing of meat samples. Result indicated that, there is a variation in the carcass characteristics, proximate composition, physico-chemical attributes and sensory evaluation. Broiler chicken live weight, slaughter weight and abdominal fat was higher as compared to sonali and indigenous/deshi chicken (P<0.05). The dry matter, crude protein and ether extract was higher in deshi chicken followed by sonali and broiler chicken (P<0.05). Drip loss and cooking loss was higher in broiler chicken followed by sonali and deshi chicken, while pH24 was lower in deshi chicken followed by sonali and broiler chicken (P<0.05). Broiler chicken meat was more tender in relation to sonali and deshi chicken (P<0.05), where flavor of deshi chicken meat was higher as compared to the broiler chicken (P<0.05). Result suggested that, based on level of status of people, consumers can choose indigenous or deshi chicken due to better proximate composition and meat flavour; however, sonali and broiler chicken are also acceptable by the consumers with higher carcass weight and meat tenderness with short interval to become marketable weight and cheap price which can be afford by all class of people to meet their protein demand, eventually can secure national human health.
Anisotropic topographies restore endothelial monolayer integrity and promote the proliferation of senescent endothelial cells

Thrombogenicity remains a major issue in cardiovascular implants (CVIs). Complete surficial coverage of CVIs by a monolayer of endothelial cells (ECs) prior to implantation represents a promising strategy but is hampered by the overall logistical complexity and the high number of cells required. Consequently, extensive cell expansion is necessary, which may eventually lead to replicative senescence. Considering that micro-structured surfaces with anisotropic topography may promote endothelialization, we investigated the impact of gratings on the biomechanical properties and the replicative capacity of senescent ECs. After cultivation on gridded surfaces, the cells showed significant improvements in terms of adherens junction integrity, cell elongation, and orientation of the actin filaments, as well as enhanced yes-associated protein nuclear translocation and cell proliferation. Our data therefore suggest that micro-structured surfaces with anisotropic topographies may improve long-term endothelialization of CVIs.
