Analyzing the 3D-MHD flow of a sodium alginate-based nanofluid flow containing alumina nanoparticles over a bi-directional extending sheet using variable porous medium and slip conditions
Authors: Aldhafeeri Anwar Ali 
Published: August 2024

Abstract
The sodium alginate (SA)-based nanofluid flow comprising alumina nanoparticles on a bi-directional extending sheet has many applications, which include thermal management, automotive radiators, industrial heat exchangers, conductive coatings, flexible electronics, electromagnetic shielding, solar panels, etc. A numerical study based on the SA-based nanofluid flow containing alumina nanoparticles over a bi-directional extending sheet in the presence of variable Darcy porous media has not yet been examined. Therefore, this study focuses on numerically investigating the flow behavior of a nanofluid of SA containing nanoparticles of alumina (Al2O3) over a bi-directional extending sheet. The variable Darcy porous media, magnetic field, thermal radiation, and thermal-dependent and space-dependent heat sources are applied to examine heat transfer flow. The velocity and thermal slip conditions have been used in the present model. The model is first shown as partial differential equations and is then converted to ordinary differential equations (ODEs). A numerical technique called bvp4c MATLAB function is applied to solve the modeled ODEs. The model is validated with previously published results. From the obtained results, it is found that high magnetic factor increases the thermal distribution, skin frictions, and heat transfer rate and reduces the velocity profiles along both directions. The Casson factor reduces the skin friction, heat transfer rate, and velocity profiles along both directions while increasing the thermal distribution. High velocities and temperature distributions of a SA-based nanofluid flow containing alumina nanoparticles are found for the scenario of no-slip condition when matched to the slip condition. It is concluded from the observed results that the percentage increase is higher for the no-slip conditions compared to the slip conditions.

Published: August 2024

Abstract
An original numerical matrix algorithm aimed at solving the optimal control problems for linear systems of ordinary differential equations with constant coefficients is proposed. The work of the algorithm is demonstrated with the problem, which consists in generating a given small disturbance of the Poiseuille flow in an infinite duct by blowing and suction through the walls. The costs of creating the leading modes and optimal disturbances are compared, which is of independent interest.
Nitrogen cycle module for INM RAS climate model

Published: August 2024

Abstract
Nitrogen is one of the most abundant chemical elements on the Earth and plays an important role in global environmental change. Leading Earth system models include coupled carbon and nitrogen cycle modules of varying complexity, but the INM RAS climate model family has not yet included an explicit N-cycle description. This paper presents a parameterization of the terrestrial N-cycle based on a simplification of the JULES-CN model, adapted for coupled use with the INM-CM land C-cycle module. Numerical simulations were carried out with a standalone carbon cycle model with nitrogen feedback disabled and enabled versions for the period 1850–2100. The simulated global pools show good agreement with results of other models with an implemented N-cycle. Taking into account the N-limitation of the C-cycle, the modelled dynamics of total carbon storage in terrestrial ecosystems from 1850 to the mid-20th century is specified.

Published: August 2024

Abstract
The paper presents an algorithm for three-dimensional modelling of two-phase flows on the scale of pore size order for numerical evaluation of relative phase permeability curves of porous materials. Such an evaluation is performed based on the results of numerical simulation of primary drainage with subsequent waterflooding. In this case, models of porous materials based on three-dimensional tomographic images of rocks are used. The simulation of the flow considers the Stokes equation and the Cahn–Hilliard equation for modelling phase transfer, which allows us to determine phases using the concentration function. The combination of the phase field method and finite difference method makes it possible to correctly take into account the contact angle and stably calculate surface tension forces in domains with complex topology.

Abstract
Kamiş, O, Gürses, VV, Şendur, HN, Altunsoy, M, Pekel, HA, Yıldırım, E, and Aydos, L. Low-load resistance exercise with blood flow restriction vs. high-load resistance exercise on hamstring muscle adaptations in recreationally trained men. J Strength Cond Res 38(10): e541–e552, 2024—Low-load resistance exercise with blood flow restriction (BFR-RE) has been suggested as a viable alternative exercise for traditional high-load resistance exercise (HL-RE). However, very little is known about hamstring muscle thickness, stiffness, and strength after BFR-RE. This study aimed to compare the effects of 6 weeks of BFR-RE and HL-RE on hamstring muscle thickness, stiffness, and strength. Twenty-nine recreationally trained men were pair matched and randomly assigned to the BFR-RE (n = 15) and HL-RE (n = 14) groups. The BFR-RE groups performed bilateral lying leg curl exercise (30-15-15-15 reps, 30-second rest between the sets, 30% 1RM) with BFR cuffs (60% of limb occlusion pressure), whereas HL-RE performed the same exercise (3 × 12 reps, 90-second rest between the sets, 70% 1RM) without BFR cuffs. Hamstring muscle thickness, muscle stiffness, isokinetic muscle strength, and 1RM were assessed at baseline and follow-up after completing a 6-week resistance exercise program (3× a week). Hamstring muscle thickness was assessed by ultrasonography, whereas muscle stiffness was evaluated by shear wave elastography. Isokinetic dynamometry and a 1RM strength test were used to determine muscular strength before and after the exercise program. Statistical significance was set at p < 0.05. No significant effect was found for hamstring muscle strength, thickness, and stiffness for group and group × time interaction, and only a significant main effect of time (p < 0.001) was observed for all outcomes. Both groups experienced significant improvements for all outcomes from baseline to follow-up without any between-group differences. In conclusion, results revealed that BFR-RE can provide similar hamstring muscle strength, thickness, and stiffness compared with HL-RE.
A RELAÇÃO ENTRE POLÍTICA E RELIGIÃO NOS DISCORSI DE MAQUIAVEL
Authors: Veliq Fabrício 
Published: August 2024

O presente artigo visa apresentar, de maneira geral, a relação estabelecida por Maquiavel entre política e religião em sua obra Discorsi sopra la prima deca di Tito Livio. Para tal, iniciamos o texto com um breve percurso histórico, no intuito de compreender o contexto em que Maquiavel escreve seu texto. Em seguida, abordamos a obra maquiaveliana em questão, bem como alguns comentadores e comentadoras, no intuito de mostrar que Maquiavel considerava a religião em dois aspectos: o primeiro, como instrumentum regni na medida em que é útil para o exercício e manutenção do poder, e o segundo enquanto algo que faz parte da cultura de um povo, sendo também responsável pela manutenção da união política interna. Nos dois modos, intentamos mostrar que a religião não é desassociada da ação política no pensamento de Maquiavel.
Flipping the Narrative: A Unifying Framework for Juvenile Court-based Forensic Social Work Practice
Authors: Walker Elizabeth Loizeaux 
Published: August 2024

Professional social workers are trained in multiple competencies and occupy various positions within the forensic landscape. Unified by a code of ethics that emphasizes social justice and the protection and empowerment of marginalized populations and a philosophical approach that recognizes the interplay of individual and environmental factors, social work leadership in youth justice policy and practice is vital. This article proposes a unifying framework for macro, mezzo, and micro court-based forensic social work practice in the 21st century that draws from post-modern critical social work theory.
The lifelong negative impacts of court involvement for young people are well documented and contribute to persistent societal inequities. Pre-disposition court practices can mitigate or further harm court-involved youth. “Flipping the Narrative” is a culturally relevant practice framework for evaluating and designing youth court practices that recognize the intersectionality of the identities and experiences of court-involved youth. The proposed framework incorporates the practical implications of Critical Theory, specifically Critical Race Theory, the Theory of African American Offending, and Queer Theory, and relevant practice approaches, such as Social Justice Youth Development and Narrative Therapy, to analyze current youth court practices, propose areas for further evaluation and innovation, and recommend practice enhancements for defense-based forensic social workers. The urgency for innovation in one New England state is illustrated through a case study.
