Lateral–Torsional Buckling of Cantilever Steel Beams under 2 Types of Complex Loads

Cantilever steel beams are an essential structural element in civil engineering fields such as bridges and buildings. However, there is very little research on the critical moment (Mcr) of cantilever beams subjected to a concentrated load (CL) or a combination of concentrated load and uniformly distributed load (CUDL) when the concentrated load is not limited to the free end. Therefore, the focus of the current paper is the calculation of Mcr for cantilever steel beams under CL and CUDL. This paper proposes a program and a simple closed-form solution for Mcr that are applicable to the elastic buckling analysis of cantilever I-beams under CL and CUDL. Based on the Rayleigh–Ritz method, a matrix equation and the corresponding procedure about Mcr under CL and CUDL are derived by using infinite trigonometric series for the buckling deformation functions. The value of Mcr and the corresponding mode of buckling can be obtained efficiently by considering the symmetry of the section, the ratio of two load values and the load action position. Experimental results and finite element calculations validate the numerical solutions of the procedure. A closed-form solution for Mcr is derived according to the assumption of a small torsion angle and the specific values of each coefficient in the closed-form solution of Mcr are calculated by the proposed procedure. The results show that the procedure and closed-form solution for Mcr presented in this paper have a high degree of accuracy in calculating the Mcr of the cantilever beam under CL and CUDL. The deviations between the results calculated by the proposed procedure and data from existing literature are less than 8%. These conclusions are capable of solving the calculation problem of Mcr for cantilever beams under CL or CUDL, which are both significant load cases in engineering. The study provides a reference for the design of cantilever steel beams.
Perceived Economic Stress and Adolescents’ Bullying Victimization: The Roles of Self-Esteem and Student-Student Relationships

In the present study, we sought to examine the relationship between perceived economic stress and adolescents’ bullying victimization and extended previous literature by examining the mediating effect of self-esteem as well as the moderating effects of student-student relationships and gender in this association. The research hypotheses were tested among 2407 adolescents from China (M age = 12.75 years, SD = 0.58) with a moderated mediation model. Results indicated that adolescents with high perceived economic stress were more likely to be bullied. Self-esteem mediated the relationship between perceived economic stress and bullying victimization. Furthermore, student-student relationships moderated the relationship between perceived economic stress and bullying victimization and the relationship between perceived economic stress and self-esteem. Gender did not moderate the direct and indirect relationships between perceived economic stress and bullying victimization. These findings have potential applications for reducing the risk of bullying victimization and promoting positive development for adolescents.
Clinico-Pathological Outcomes of Patients With Crescentic Glomerulonephritis: A Single-Center Study

Background Crescentic glomerulonephritis (CrGN) is a pathological description of rapidly progressive glomerulonephritis (RPGN). It is characterized by renal failure and is associated with a grave prognosis. This study aimed to investigate the clinical outcomes of patients diagnosed with crescentic glomerulonephritis at the King Abdulaziz University Hospital (KAUH) in Jeddah, Saudi Arabia. Method This retrospective study included patients with CrGN who underwent treatment at the nephrology department at KAUH from June 2021 to August 2022. We collected and analyzed data from 56 patients diagnosed with CrGN on the basis of renal biopsies between 2002 and 2015. Result The study included 17 cases of CrGN. The mean age of patients at the time of diagnosis was 18.06 ± 13.49 years. The distribution of histological findings showed that cellular crescents (94.1%) and interstitial fibrosis and tubular atrophy (IFTA) (76.5%) were the most commonly observed histological findings. The most common underlying etiology was lupus nephritis (41.2%). Regarding the lab results, the mean serum creatinine level at admission was 378.88 ± 273.27 μmol/L, proteinuria was 1.53 ± 1.23 and glomerular filtration rate (GFR) level was 36.94 ± 45.08 mL/min. The factors associated with poor renal outcome were IFTA (P=0.01), phosphate level before discharge, serum creatinine level before and after discharge (P=0.032), and GFR level after discharge (P=0.001). Conclusion Crescentic glomerulonephritis is an important cause of acute kidney injury due to its potential to result in severe glomerular injury. In our study, 12 out of 17 patients experienced poor renal outcomes, which were associated with a high risk of morbidity and mortality. Therefore, early detection and treatment of CrGN is crucial in order to manage the disease.
Impact of body mass index on semen parameters and reproductive hormones among men undergoing microsurgical subinguinal varicocelectomy

ABSTRACT Background Few studies assessed the relationships between BMI and post varicocelectomy semen quality and fertility potential and they reported inconsistent findings. Objective To assess the association of BMI with semen parameters and reproductive hormones before and after microsurgical varicocelectomy. Materials and Methods Retrospective chart review in a tertiary infertility center. Of 1170 patients with clinical varicocele during the study period (8 years), 813 patients were eligible and included. Patients were grouped into: Group A (kg/m2, n = 251 patients), B (BMI 25–29.9 kg/m2, n = 289), C (BMI 30–34.9 kg/m2, n = 183) and D (kg/m2, n = 90). Clinical data, semen parameters, sperm DNA fragmentation and hormonal profile were collected before and 3 months after microsurgical varicocelectomy. Results Patients’ mean age was 35.87 ± 8.17 years. Higher-grade varicocele was significantly more prevalent in the lower BMI groups. BMI was significantly negatively correlated with preoperative sperm concentration, total motility progressive motility and total motile sperm count. Pre-operatively, sperm concentration, total motility, progressive motility and total motile sperm count showed significant differences between BMI groups, where higher BMI (Groups C and D) exhibited the poorest semen parameters. Postoperatively, all groups showed significant improvement in sperm concentration compared with pre-operative values. However, total and progressive motility were significantly improved in Groups A, B and C, while in Group D (highest BMI), total motility improved clinically but not statistically, progressive motility did not display improvement, and total motile sperm count was significantly improved only in Groups B and C. Postoperatively, mean improvements in semen parameters across the BMI groups were not significantly different, except for morphology, which improved significantly more in the less obese patients. Conclusion For infertile patients with clinical varicocele undergoing micro-surgical varicocelectomy, BMI appears not to impact the improvements across most of the semen parameters and hormones. The procedure might improve the fertility potential.
Illicit Online Pharmacies: A Scoping Review

This scoping review presents the extent and nature of the body of literature on illicit online pharmacies (IOPs) and identifies research gaps. Using the five-step framework developed by Arksey and O’Malley, we searched PubMed, Web of Science, EMBASE, CINAHL, Science Direct and PsycInfo to retrieve relevant studies published in English in peer-reviewed journals. The search strategy identified forty-three articles that met the inclusion criteria. Ten themes were identified and categorized into five clusters: patient risk, healthcare providers, marketing and supply chain, public health and society, and policy and regulation. Research into these clusters has evolved over time and has focused increasingly on issues related to specific drugs rather than the overall phenomenon. Data collection has been dominated by convenience sampling, online searches, content analysis and surveys. Data analysis remains primarily descriptive. Gaps within the extant literature suggest an agenda for future research into regulation and enforcement; public health awareness and education; healthcare services; risks to patients and public health; patient-, price- and product-related issues; website design; social media promotion; and supply chains and logistics. We conclude that IOPs are vastly understudied and suggest an urgent need for further empirical and conclusive research.
FENUGREEK SEEDPROTEIN ISOLATE: AMINOACID COMPOSITION AND FUNCTIONALPROPERTIES

: With increasing demand for new protein sources, research on plant protein extraction and evaluation of the functional properties of protein isolates is necessary. Proteins were obtained from fenugreek seeds. Protein solubility, emulsifying capacity and emulsion stability, foaming capacity, and foam stability were used to determine the fenugreek a chemical composition and functional properties of proteins. The profiles of the solubility curves corresponding to the participating fenugreek protein indicate a minimum solubility at pH2. The emulsifying capacity of fenugreek participated fenugreek protein was low (3.2%) but it has high emulsifying stability (98.9%). Fenugreek proteins have show a high foaming capacity at pH 2 and the suitable time to form the foam is 30 min. the high stability of foam was 78.8%. The result of this study emphasized that fenugreek protein has a greater ability to absorb water than oil. Thus, the experiments suggest that fenugreek protein can be successfully used as a food ingredient due to its nutritional value, chemical composition, and functional properties.
Entropy generation in rectangular microchannels

Entropy generation in a rectangular microchannel with fully developed steady gaseous flow at slip flow regime is studied. Two different thermal versions, uniform temperature (H1) and uniform heat flux (H2) on the walls, are considered. Analytically obtained expressions for temperature and velocity fields are used for entropy generation calculations. The effects of rarefaction, geometry, Peclet number Pe and group parameter Br/ on entropy generation (irreversibility) and local variation of entropy generation are explored. The main findings are; irreversibility decreases with rarefaction regardless of the thermal versions, irreversibility increases with aspect ratio for H1 thermal version and exhibits very little change with aspect ratio for H2 thermal version. For H1 thermal version the points of maximal entropy generation are at the middle of walls. For H2 thermal version entropy generation is generally high at immediate vicinity of walls and decreases by departing the walls toward the centre of the microchannel.
“We Got to Fight for What We Want”: Black School Rebellions In Louisiana, 1965–1974

Background/Context: Historians have established that Black students used force to challenge racist repression in schools throughout the United States during the 1960s and 1970s. However, the existing literature’s national focus raises unanswered questions about the extent to which Black students’ forceful responses to discrimination varied across local contexts. Focus of Study: This article examines 42 episodes from Louisiana secondary schools in which Black students collectively used force to resist subordination between 1965 and 1974. Drawing upon Black Studies scholarship, it treats these incidents as political acts of rebellion rather than lawless “riots. ” Research Design: To determine where, when, how, and why Louisiana’s Black students used force, this historical study draws upon archival materials from eight collections at five archives, more than one dozen local and national newspapers, and author-conducted interviews. Conclusions/Recommendations: Although Black students acted on shared concerns about systemic inequality, site-specific factors shaped each rebellion. This essay therefore argues that scholars should not mistake the ubiquity of Black students’ violent opposition to white supremacy as an indication that subordination or resistance remained static across time and space. It encourages further localized study that is attentive to the temporal and geographic contingencies that shape the racial politics of education.
EFFECT OF DIETARY ω-3, ω -6 AND ω -9 FATTY ACIDS ON PRODUCTIVE AND PHYSIOLOGICAL TRAITS OF LAYING HENS

SUMMARY his study investigated the effect of various sources and levels of vegetable oil as a source of omega-3, omega-6 and omega-9 fatty acids on productive performance, egg quality, fatty acids profile and some physiological traits of laying hens. Two hundred and seventy Bovens laying hens at 45 weeks of age were randomly divided equally into nine treatments resulting from factorial design (3×3); three sources of vegetable oil (soybean, sunflower and linseed oil) with three levels (1, 1.5 and 2%). Obtained results showed that, final body weight, hen-day egg production percentage, feed consumption, egg quality characteristics, plasma total protein, globulin, aspartate transaminase, alanine aminotransferase, total lipids and very low density lipoprotein concentrations were not significantly affected (P>0.05) by various sources or levels of vegetable oils. The use of linseed oil in laying hens' diets led to a significant increase (p≤0.05) in the egg mass and weight of eggs produced from those hens. Feed conversion ratio of laying hens fed either linseed or sunflower oil diets were significantly (P≤0.05) improved compared to those received dietary soybean oil. There was a significant increase in the level of MUFAsin the egg yolk occurred as a result of using sunflower or linseed oil, compared to soybean oil. The inclusion of sunflower oil in the layer diets was able to improve significantly (P≤0.01) the concentration of γ-linolenic (C18:3n6) and arachidonic (C20:4n6) fatty acids in the egg yolk. The use of different levels of sunflower or linseed oil up to 2% led to a significant (P≤0.01) improvement in the level of high density lipoprotein. Moreover, layer fed diet with different levels of linseed oil significantly (P≤0.01) had the lowest concentration of low density lipoprotein. Significant (P≤0.01) improvement in the level of antioxidants was observed for the groups fed on diet containing linseed oil, followed by those fed dietary sunflower oil, compared to the control group that fed on soybean oil. In conclusion, the use of both sunflower oil or linseed oil up to 2% in the diet of laying hens are able to improve egg production, egg quality, the level of essential fatty acids in egg yolk, in addition improving the level of antioxidants and blood biochemical parameters.
Psychometric Properties of PERMA Proﬁler Scale in Argentinian Adolescents

Abstract. Aim. To adapt and validate the PERMA Proﬁler Scale (Butler & Kern, 2016) for Argentinian adolescents. Method. The items were reviewed by 6 expert judges and 21 adolescents. The sample consisted of 421 adolescents (M = 14.9; SD = 1.75). The content validity and the discrimination capacity of the items were assessed. Afterwards, the structure of the scale was analyzed, as well as the internal consistency and the concurrent validity. Results. All the items obtained an Aiken’s V between . 8 and 1 and were discriminatory. The factor analysis conﬁrmed the ﬁve-dimension structure (CFI = .94, T LI = .92; RMSEA = .08, SRMR = .04). An Alpha of . 92 was obtained for the full scale and satisfactory levels were obtained for the subscales. The correlations for concurrent validity were signiﬁcant and in line with what was theoretically expected. Conclusion. This adaptation enables the assessment of ﬂourishing in a practical way.
Characteristic Gut Bacteria in High Barley Consuming Japanese Individuals without Hypertension

Background: Barley, a grain rich in soluble dietary fiber β-glucan, is expected to lower blood pressure. Conversely, individual differences in its effects on the host might be an issue, and gut bacterial composition may be a determinant. Methods: Using data from a cross-sectional study, we examined whether the gut bacterial composition could explain the classification of a population with hypertension risks despite their high barley consumption. Participants with high barley intake and no occurrence of hypertension were defined as “responders” (n = 26), whereas participants with high barley intake and hypertension risks were defined as “non-responders” (n = 39). Results: 16S rRNA gene sequencing revealed that feces from the responders presented higher levels of Faecalibacterium, Ruminococcaceae UCG-013, Lachnospira, and Subdoligranulum and lower levels of Lachnoclostridium and Prevotella 9 than that from non-responders. We further created a machine-learning responder classification model using random forest based on gut bacteria with an area under the curve value of 0.75 for estimating the effect of barley on the development of hypertension. Conclusions: Our findings establish a link between the gut bacteria characteristics and the predicted control of blood pressure provided by barley intake, thereby providing a framework for the future development of personalized dietary strategies.

Practical implications – This study shows a relationship between Islamic leadership, organizational culture, self-efficacy, and OCB variables on lecturer performance and gives the importance of strengthening OCB to improve lecturer performance.
Non-equilibrium Shock Structure Calculation with High-order Modified Navier–Stokes Equations

Abstract High-order modified Navier-Stokes (NS) equations are introduced to describe the transitional flow derived from Burnett equations considering the inaccurate simulation of shock structure using traditional NS continuum methods, particularly at high Mach numbers. This process is performed by defining the effective transportation coefficient, which is associated with Mach number, molecule propriety, and continuum failure criterion. Within this method, the linear Stokes and Fourier relationships are replaced by nonlinear constitutive relationships to describe transitional flow. The traditional NS equation formulation is preserved. The shock structures of both monatomic and diatomic gases are concentrated with different Mach numbers to validate the accuracy and effectiveness of the derived method. The comparison of shock structure with DSMC and Burnett equations shows that the high-order modified NS equations obtain better results than traditional NS equations in terms of shock wave, particularly at high Mach numbers. The modified NS equations also capture the significant features of Burnett equations in shock structure simulation.
A Comparative Study of Intralesional Acyclovir vs Immunotherapy for Treatment of Viral Warts

Background: Viral warts are caused by human papillomavirus (HPV), are difficult to treat with conventional modalities, and are cosmetically disfiguring; hence, immunomodulators are being used. The viral origin of warts suggests the antiviral drug acyclovir as a potential therapeutic option. The current study compares the effect of intralesional acyclovir (nucleoside analogue) and intralesional purified protein derivative (PPD) (immunotherapy) in treating various viral warts. Methodology: Prospective observational comparative study was conducted to determine the efficacy of acyclovir, and PPD administered via the intralesional route in patients with viral warts. The study population was categorized into two groups. One group received intralesional acyclovir, and the other received intralesional PPD. Patients were followed-up with for three months. Outcomes considered in our study were recovery (complete, partial, and no recovery) and side effects like pain, burning sensation, and desquamation. Statistical analysis was carried out by coguide software. Results: In our study total of 40 participants, 20 in each group were included. 25 and 15 were of age <30, and ≥ 30, respectively, while 20 were males, and 20 females. Our study reported 60%, and 30% of complete recovery with intralesional acyclovir treatment and intralesional PPD treatment, respectively, in the twelfth week. However, p-value > 0.05 represented no significance between groups. 90% in the acyclovir-treated group presented with pain, and 100% presented with burning sensation, while in the case of PPD-treated group, 60% presented no side effects and the rest 40% showed pain. Conclusions: Intralesional acyclovir is more effective in treating viral warts than PPD. The focus is to be laid on anticipated side effects.
