Authors: Powell Robert M , Swords Michael , Rodeghier Mark , Budinger Phyllis 
Published: May 2022

A sample from the Ubatuba fragment collected in Brazil in 1957 was tested with the intent of examining the isotope ratios of its primary element, magnesium, and the trace elements strontium, barium, copper, and zinc. As background, the history of chemical testing of the Ubatuba fragments during the 1960s-1980s at multiple labs with varying capabilities is reviewed and then the remainder of the paper examines recent tests completed in 2017 and 2018 that for the first time used HR-ICPMS techniques to look at the isotopic ratios of the minor constituents as well as the primary magnesium makeup of the sample. The magnesium isotope ratios were found to fall within terrestrial limits while the results on the isotope ratios of the trace elements was inconclusive. Recommendations are made for improving the process of examining the trace elements.

Disordered Eating and Sexual Concerns in Chinese and Euro-Caucasian Undergraduate Women
Authors: Svatko Yana , Dunkley Cara R. , Brotto Lori A. 
Published: May 2022

While a growing body of research points to considerable sexual concerns among women with an eating disorder, this research predominantly focuses on Western samples of Euro-Caucasian women. As eating disorder rates continue to increase globally, research on sexuality and disordered eating among ethnically diverse samples is needed to understand whether these associations differ cross-culturally. The present study examined disordered eating and sexual concerns in Chinese and Euro-Caucasian undergraduate women. Chinese ( n = 512; Mage = 20) and Euro-Caucasian ( n = 494; Mage = 21) undergraduate women completed online questionnaires assessing sexual function, sexual insecurities, symptoms of disordered eating, body dissatisfaction, and psychological traits of eating disorders. In both samples, body dissatisfaction, eating disorder symptoms, and psychological traits of eating disorders were associated with increased sexual concerns. Group membership only moderated the associations between disordered eating and performance-based cognitive distractions, such that it was stronger in Euro-Caucasian women. These findings might be used to develop cross-cultural interventions that address sexual concerns and disordered eating.

Published: May 2022

Purpose: The objective of our study was to analyze visual and textual content of private physiotherapy clinic Web sites with a critical analysis framework. Method: We analyzed 43 private physiotherapy clinics’ Web sites from all regions of one Canadian province (Quebec). For each Web site, we collected and aggregated the data using a standardized extraction grid to index visual and textual content. We then conducted an analysis of the collected data using the Seven-Step Framework for Critical Analysis proposed by Nixon and colleagues. Results: Most Web sites presented elements related to sports and active lifestyles in their names, logos, or pictures. Persons represented in the Web sites were mainly young, white, and active. Ethnic and body diversity were generally not depicted. Information encompassing manual therapy and sports injuries management largely prevailed. Conclusions: The textual and visual content of private physiotherapy clinic Web sites was not consistent with the physiotherapy community’s commitments to upholding equity principles and to serving a wide range of individuals. To fulfill the highest professional and ethical standards, the physiotherapy community should reflect on the representation of physiotherapy services and clients on Web sites to ensure that the trend towards privatization of physiotherapy services does not perpetuate the systems of inequality present in society.

Authors: Lira Munizaga Juan , Pérez-Salas Claudia 
Published: May 2022

The Superior Education Access Program (PACE: Programa de Acceso a la Educación Superior) in Chile is an initiative that aims to provide a better possibility for equity in the access to higher education for students from less wealthy backgrounds and to promote persistence in their studies. Economically disadvantaged students are at greater risk of dropping out. Therefore, the study of variables intervening in dropout is a major concern to the Program.The academic engagement construct offers predictive insights into academic achievement and student attrition. Evidence about the characteristics of student engagement in vulnerable populations is mixed, with some researchers claiming that such students show higher engagement when entering university while others disagree. This investigation aims to compare the academic engagement and disengagement between PACE students in their first yearÂ and their first-year peers at Universidad de Concepción in Chile.The study findings show a significantly higher emotional engagement in PACE students, suggesting a deeper affective attachment with their educational institution and a lower behavioral disengagement. That is, students are more respectful to the institutional norms.Â

The punishment for the perpetrator of murder is not always required qishas, but it can be done with the payment of Diyat in exchange for the Qishas punishment, in some provisions even the victims’s heir is given the right to choose between Qishas or aplogize. Giving forgiveness is the closest heir of the victim such as husband / wife, father, mother, and child (male / female), and also brothers (male / female), uncle, aunt. The consideration of forgiveness is the motivation to gain rewards, alms, penance, the way to taqwa, forgiveness is one of God's commands. The Apology is filed by the murderer himself or his family, it is asked to the guardian of the murder victim. If the family’s victim decides to apologize the murderer, the offender must pay Diyat in accordance with Islamic Law provision.

Relevance. The study aimed to develop the composition of an artificial nutrient medium for the rearing of Gallery mellonella larvae. In the process of the research, the relative contributions of the feed component to the biological growth parameters of larvae and their morphological indicators were determined.Methods. In the experiment the plan 27-4 was used, that is, fractional factor experiments were varied in which seven factors — feed ingredients. The matrix of the complete factor experiment 23 was taken as a basis, and the coefficients in the interaction of three or more factors were assumed to be insignificant and replaced by additional factors. Morphophysiological parameters of larvae were used as the main indicators: mass, length, width of the head capsule.Results To obtain biomass in the production cycle, the mass of larvae should be at least 0.15 g, length 20-22 mm, width of the head capsule 1.9-2.3 mm (VI-early VII age), survival rate of at least 85%. In the regression equation for larval masses, wheat flour (X1), yeast (X3) and honey (X5) turned out to be significant ingredients. In the regression equation for the length of the larvae, the ingredients that make the maximum contribution are again yeast (X3) and honey (X5). Yeast (X3) was significant for the width of the head capsule. The obtained regression equations enable mathematical modeling within the framework of a linear model represented by regression equations in the studied range of morphological parameters of larvae, depending on the composition of the feed.

Introduction. According to world statistics, some of the young teachers leave educational organizations. The reason is in the “axiological conflict”: the contradiction between the value orientations of the teacher himself and the values of the education system. The desire to resolve this contradiction determines the purpose of the study: to determine the content and methods of forming the value orientations of young teachers as a predictor of their professional detail. Materials and methods. The theoretical part of the study is based on the analysis and generalization of primary sources on the problem under study. Empirical methods are presented by a formative experiment conducted on the basis of the author's program of additional professional education, aimed at resolving the axiological conflict of young teachers. Value orientations were studied using the methodology of N. A. Samoilik "Diagnostics of the professional and value orientations of the individual". The results were processed using the methods of mathematical statistics (Student's t-test). The study involved teachers of the Kirov region with work experience from 1 to 5 years (N = 161 people). Research results. It has been empirically proven that the program of additional professional education causes positive dynamics in the development of value orientations of novice teachers: in the emotional (the difference between the results of the input and final diagnostics was 2.75 walls), cognitive (2.6), and behavioral (2.3) components. The empirical value for each criterion is tCR = 1.99 at p ≤ 0.05, tCR = 2.64 at p ≤ 0.01. The greatest changes have occurred in such structural components of value orientations as: "values - goals" (3.5), "values - relationships" (2.8) and "values - skills" (2.7). Less changed were "values - qualities" (1.9), "values - result" (2.0) and "values - knowledge" (2.4). Discussion and conclusions. The reasons for the axiological conflict, caused by the contradictions between: the values of the education system and the requirements imposed on it by society, the state and the market, have been determined; "Values-expectations" to the young teacher and his value orientations. The effectiveness of the author's additional professional program in the development of the emotional, cognitive and behavioral components of the value orientations of novice teachers has been proved.

The aim of the study is to look into the nurse’s views of the conflict in family and work demands working in various hospitals of Sargodha District. The study follows a quantitative methodology hence survey research design is considered as the most appropriate research design for this research. Structured questionnaires was developed containing 21 items. Data was collected through personal visits. The population for this study was nurses working in government and private hospitals of district Sargodha. For the respondent selection, a multi-stage sampling method was used. In first stage six government and private hospitals were selected through simple random sampling. Target was three government and three private hospital located in district Sargodha. Purposive sampling was employed in the second stage of sampling to choose a sample of 150 nurses from randomly selected hospitals. Results from the study showed that work family conflict was more evident among nurses aged 25-35 and married having 1-3 children. The result of the study showed that as compared to family demands, work demands are more strongly associated with work family conflict. The study recommends that work family conflict should continue to be researched further. In particular, a national study of nurses and the profession should be conducted. The nursing profession’s collective voice ought to be heard in Pakistan.

Aim: Trans-arterial chemoembolization (TACE) in combination with tyrosine kinase inhibitor (TKI) has been evidenced to improve outcomes in a portion of patients with hepatocellular carcinoma (HCC). Developing biomarkers to identify patients who might benefit from the combined treatment is needed. This study aims to investigate the efficacy of radiomics/deep learning features-based models in predicting short-term disease control and overall survival (OS) in HCC patients who received the combined treatment.Materials and Methods: A total of 103 HCC patients who received the combined treatment from Sep. 2015 to Dec. 2019 were enrolled in the study. We exacted radiomics features and deep learning features of six pre-trained convolutional neural networks (CNNs) from pretreatment computed tomography (CT) images. The robustness of features was evaluated, and those with excellent stability were used to construct predictive models by combining each of the seven feature exactors, 13 feature selection methods and 12 classifiers. The models were evaluated for predicting short-term disease by using the area under the receiver operating characteristics curve (AUC) and relative standard deviation (RSD). The optimal models were further analyzed for predictive performance on overall survival.Results: A total of the 1,092 models (156 with radiomics features and 936 with deep learning features) were constructed. Radiomics_GINI_Nearest Neighbors (RGNN) and Resnet50_MIM_Nearest Neighbors (RMNN) were identified as optimal models, with the AUC of 0.87 and 0.94, accuracy of 0.89 and 0.92, sensitivity of 0.88 and 0.97, specificity of 0.90 and 0.90, precision of 0.87 and 0.83, F1 score of 0.89 and 0.92, and RSD of 1.30 and 0.26, respectively. Kaplan-Meier survival analysis showed that RGNN and RMNN were associated with better OS (p = 0.006 for RGNN and p = 0.033 for RMNN).Conclusion: Pretreatment CT-based radiomics/deep learning models could non-invasively and efficiently predict outcomes in HCC patients who received combined therapy of TACE and TKI.

ObjectiveTo systematically examine the association between metformin and abdominal aortic aneurysm (AAA) and provide a basis for the treatment of AAA.MethodsPubmed, Embase, Cochrane Library, and Ovid databases were searched by computer to identify the literature related to metformin and AAA published until February 2022. The literature was screened according to the inclusion and exclusion criteria, data were extracted, and a quality assessment was conducted. The meta-analysis was performed using Stata 16.0 and RevMan 5.3 software.ResultsSeven articles containing a total of 10 cohort studies (85,050 patients) met the inclusion criteria and were included in the review. Meta-analysis showed that metformin can limit the expansion of AAA (MD = – 0.72, 95% CI: – 1.08 ~ −0.37, P &lt; 0.00001), as well as reduce AAA repair or AAA rupture-related mortality (OR = 0.80, 95% CI:0.66 ~ 0.96, P = 0.02). The difference was statistically significant (P &lt; 0.05).ConclusionMetformin can limit the expansion of AAA and reduce the incidence of AAA and postoperative mortality. However, further biological experiments and clinical trials still need to be conducted to support this.
Experimental Study on the Heat Transfer Characteristics of an Inclined Shell-and-Tube Phase-Change Thermal Energy Storage Unit
Authors: Zhang Kun , He Xiaoliang , Wang Liangbi , Yu Yan 
Published: May 2022

Detailed experimental investigation is presented for the heat transfer characteristics of an inclined shell-and-tube phase-change thermal energy storage unit. For the case of inclined angle α = π/4, the solid–liquid interface presented a concave surface because the heat transfer can be affected not only by conduction in the phase-change material (PCM) domain but also by natural convection significantly. The heat transfer rate increases with the increasing flow rate and inlet temperature of heat transfer fluid (HTF), but the flow rate of the HTF has little effect on the charging process for the case of qv ≥ 40 L/h. The heat transfer rate of PCM above the HTF tube increases with the increase of inclined angle. The effects of inclined angle on the heat transfer rate can be not negligible due to the obvious natural convection in the charging process.

Published: May 2022

Background: Pearson’s syndrome (PS) is a rare multi-system disorder caused by mitochondrial DNA deletion. Most PS cases in the literature are individual reports, and there is a lack of systematic analysis of clinical features and gene mutations in large samples.Objective: To report a case of PS and summarize the clinical features and genetic characteristics of PS by reviewing the literature.Methods: We reported a case of PS in a boy with severe anemia and multi-system disorder. Genetic etiology was identified by mitochondrial DNA sequencing and whole-exon sequencing. Clinical features and gene mutations were summarized by literature review.Results: The patient had major clinical manifestations with recurrent anemia and multiple organ failure after infection. Mitochondrial DNA sequencing revealed a de novo heteroplasmic deletion of 3.063 kb (nt 6,224–9,287) with 75% heteroplasmy in peripheral blood. A total of 139 PS cases were retrieved after a literature search. The most common initial symptom was refractory anemia requiring repeated blood transfusion (86.2%), digestive system symptoms (26.9%), and failure to thrive (15.4%). During the course of disease, the observed symptoms were bone marrow failure (100%), metabolic disorders (61.87%) and gastrointestinal symptoms (61.87%), failure to thrive (48.9%), renal disorders (42.45%), and pancreatic exocrine insufficiency (39.6%). The mean heteroplasmy of mitochondrial DNA mutation in peripheral blood in deaths (76.29 ± 11.86%, n = 29) was higher than that in survivals (59.92 ± 23.87%, n = 26, p &lt; 0.01). Among the patients with the 4.977 kb deletion, the heteroplasmy in peripheral blood in deaths (79.64 ± 9.71%, n = 11) was higher than that in survivals (56.67 ± 27.65%, n = 9, p &lt; 0.05).Conclusion: PS can affect multiple systems, and mitochondrial DNA sequencing should be performed early. The heteroplasmy in peripheral blood is related to prognosis.
