Geogrid-soil interaction: experimental analysis of factors influencing load transfer
Authors: Derksen J. , Fuentes R. , Ziegler M.
Published: May 2022

This paper presents interaction experiments with transparent soil to investigate the load transfer at the interface of different geosynthetic reinforcements. Microscopic interaction performance was evaluated in terms of mobilised tensile loads and interfacial shear stresses resulting from the relative movement between geosynthetic and soil. The effects of geogrid aperture size, tensile stiffness, geogrid type and reinforcement configurations on the load transfer were analysed. It was found that with increasing soil deformation, the contribution of friction to the total load transfer decreased and the transverse ribs were increasingly activated. The interfacial shear stresses were reduced as the ratio of geogrid aperture to mean particle size increased, resulting in lower geogrid loads. Higher geogrid loads were mobilised with increasing tensile stiffness of the reinforcement, but lower displacements of geogrid and adjacent soil occurred. Consistent results were found for woven PET and laid PP geogrids. The most effective load transfer was obtained for the aperture configuration with two closely spaced transverse members at each rib, as the soil particles were additionally confined. When the geogrid was attached to a nonwoven geotextile, the separation function was enabled, but the reinforcement performance of the geocomposite was lower due to reduced particle-aperture interaction.
Analytical solution for solute transport in a triple liner under non-isothermal conditions
Authors: Qiu J. , He Y. , Song D. , Tong J.
Published: May 2022

Analytical solutions for the transport of contaminant through a 1D triple-layer composite liner system consisting of a geomembrane (GMB), a geosynthetic clay liner (GCL) and a compacted clay liner (CCL) under non-isothermal conditions are derived using the generalized integral transform technique. The proposed analytical solutions account for the combined effects of molecular diffusion, sorption and thermodiffusion as well as the temperature-dependent distribution coefficient and effective diffusion coefficient. The proposed analytical solutions are successfully validated against the experimental results of thermodiffusion tests and verified against an analytical solution available in the literature and a numerical model based on commercial finite element software. Using the verified analytical solutions, simulations are performed with representative geometry and material properties for a GMB/GCL/CCL liner system. The results indicate that neglecting the effect of non-isothermal condition can underestimate the benzene outflow rate by over 30% when the temperature difference between the surface and bottom of the liner system exceeds 10 K. The temperature-dependent CCL effective diffusion coefficient and CCL distribution coefficient have a significant effect on benzene transport through the GMB/GCL/CCL liner system, whereas the liner thermal conductivity and the temperature-dependent GCL effective diffusion coefficient and GCL distribution coefficient have a negligible effect.
Instability of gold mine tailings subjected to undrained and drained unloading stress paths
Authors: Fotovvat Amirreza , Sadrekarimi Abouzar , Etezad Michael
Published: May 2022

The drained instability of two gold mine tailings under lateral stress relief is investigated in this study. Constant deviator stress (CDS) unloading tests were performed using a triaxial apparatus to examine instability imposed by unloading in a drained condition. Instability was induced by enforcing a constant deviator stress while simultaneously reducing the mean effective stress. Stress paths and shear strengths of CDS tests were compared with undrained triaxial tests on comparable specimens which were anisotropically consolidated to the same initial stress ratios of the CDS tests. Several techniques were employed to determine the onset of instability in the CDS tests. The effects of unloading rate and initial stress ratio on the behaviour and the triggering of instability in the CDS tests were further investigated. It was observed that specimens consolidated to the same void ratio and initial stress ratio undergo instability at similar stress ratios or friction angles in both CDS and undrained shear tests. This suggests that the instability characteristic of tailings prone to stress relief can be predicted using undrained triaxial tests on anisotropically consolidated specimens. Critical states and state parameters of specimens subjected to CDS and unloading stress paths were also compared and analysed.

Published: May 2022

Troublesome events are related to the stabilisation of sulfate-rich soils with calcium-based materials. To overcome these inconveniences, research studies have been conducted applying modified and alternative treatments to soils containing low and high sulfate levels. This paper intends to assess the effects of mellowing period (MP) (2 and 4 days), Portland cement content (5%, 7% and 9%), density (15.75, 16.60 and 17.50 kN/m3) and curing time (14 and 28 days) on the performance of a clayey soil from the Paraguayan Chaco region containing high amounts of sulfates. A complete factorial design set was carried out to assess the unconfined compressive strength (UCS) and the one-dimensional free vertical swelling of compacted soil–cement–lime mixtures. The results showed a positive effect of the MP relative to the swelling of the stabilised soil. In addition, the curing period, the amount of cement and the dry unit weight were the most influential factors regarding the UCS. The stabilisation method addressed in this research – that is, extended mellowing combined with lime and Portland cement, seems to be of great importance for practical purposes on the stabilisation of soils containing high amounts of sulfates.
Edge punching shear of waffle slabs subjected to moment parallel to the slab's free edge
Authors: Al-Bayati Ahmed Faleh , Lau Teck Leong , Clark Leslie A.
Published: May 2022

The test results of five one-tenth scale micro-concrete waffle slabs subjected to edge punching shear in the presence of moment transfer parallel to the slab's free edge are presented. Although the observed punching failure mechanism of the waffle slabs was found to be very similar to that of a flat slab, the shear capacity was reduced because some of the potential failure surface is lost when it extends into the waffle section. Since the current codes of practice do not specifically consider the punching shear mechanism of waffle slabs, comparisons with test results revealed that the application of various codes overestimated the punching capacities of waffle slabs. An upper-bound plasticity theory model was developed to predict the punching shear failure load. The proposed model assumes concrete to be a perfectly rigid plastic material with the modified Mohr–Coulomb failure criterion. The model showed good agreement with the test results.

Authors: Xiao Jianzhuang , Poon Chi Sun , Zhao Yuxi , Wang Yuyin , Ye Taohua , Duan Zhenhua , Peng Ligang
Published: May 2022

Although recycled aggregate concrete (RAC) has been extensively studied, several critical problems with its fundamental behaviors still urgently need to be figured out. Therefore, this series of two reviews re-thinks fundamental behaviors of RAC based on the latest literature. In the last review (part I), the mechanical and deformation behaviors of RAC were intensively discussed. Here in part II, the relationships between the replacement ratio of recycled aggregates (RA) and the durability of RAC are further presented. It is found that, owing to the increase of total porosity, the resistance of RAC to freeze–thaw cycles, carbonation, and chloride ion penetration is usually decreased with the increasing replacement ratio of RA. As a result, the steel corrosion and corrosion-induced cracking in RAC are more serious than those in natural aggregate concrete (NAC). The prediction models for carbonation and chloride ion penetration of RAC and the corrosion-induced crack patterns are also presented. To address the degradation on the performance of RAC, several enhancement technologies such as the combined/optimisation pre-treatment on RA and fiber reinforcement are put forward. Finally, the prospects of the high-performance/efficiency methodologies and applications of RAC are also shown.

Inicios de la Comunicación Social: de la razón crítica al auge de la razón instrumental
Authors:   Universidad de Buenos Aires (UBA), Entel Alicia
Published: May 2022

Los estudios de Comunicación Social en sentido amplio, que ya han recorrido un siglo en América Latina, se enriquecieron en sus inicios con las dimensiones políticas, sociales, culturales – a veces en tensión- así como con un conjunto de perspectivas teóricas y metodológicas que les permitieron desarrollar prospectiva, anticipar futuro. Tales posibilidades han atravesado un periplo que no los dejó inmunes frente al impacto de los modos de construir poder del capitalismo neoliberal así como de sus legitimaciones socioculturales. El artículo intenta demostrar cómo las huellas de dicha visión de mundo han impactado y puesto en riesgo a la densidad del propio campo. De ahí el pensar en el deslizamiento de la razón crítica al auge de la razón instrumental.

El periodismo enfrenta retos que han puesto en peligro su continuidad y la confianza del público. Algunos toman forma por el incremento de las fake news. El objetivo del estudio es conocer la percepción y experiencia de periodistas de la Comunidad Andina, a través de 12 entrevistas en profundidad, con miras a identificar claves para su futuro. Los resultados reflejan que los periodistas se autoperciben como competentes para confrontarlas, y que los mayores retos son: la priorización de contenidos light, la competencia fomentada por el prosumo y las nuevas exigencias laborales. Se concluye que existe una necesidad latente de formación respecto a nuevos modelos de negocio y contenidos periodísticos, junto al desarrollo de políticas empresariales, que permitan fortalecer la profesión.

Los medios de comunicación facilitan los procesos de socialización, en un contexto donde la interactividad, la digitalización y el desarrollo de plataformas avanza de forma vertiginosa, y la ciudadanía demanda el desarrollo de competencias que potencien capacidades y promuevan el ejercicio de derechos con responsabilidad, independencia y autonomía. La comprensión crítica es una dimensión de la competencia mediática que, desde la toma de conciencia, se corresponde con el pensamiento crítico para resolver problemas. En la presente investigación, se presentan resultados de la aplicación de un cuestionario a 2158 jóvenes usuarios de redes en Bolivia, Colombia y Ecuador. El objetivo del estudio fue explorar la comprensión crítica como una de las dimensiones de la competencia mediática, y se concentró en las capacidades de: lectura, comprensión y evaluación. Se observó que los jóvenes tienen desarrollada la comprensión crítica, con autonomía, que muestra una propia lectura y resignificación de los medios, más allá del determinismo tecnológico. Por esa razón, es necesario el fortalecimiento del potenciamiento crítico ante los contenidos que reciben y producen los jóvenes, con el acompañamiento de docentes que accedan a la formación en educación mediática, para avanzar en un proceso transformador e integral.

Freire más allá de Freire: a cien años de su nacimiento
Authors:   Flacso, Cerbino Mauro
Published: May 2022

En este texto se elabora un mapa conceptual que se compone de tres problemas para pensar la sociedad contemporánea con la contribución de Paulo Freire. Se describen cada uno de ellos y asoman así tres facetas de Freire: política, epistemología y ética. Así también, se intenta pensar a Freire más allá de Freire, gracias a las resonancias o convergencias que se evidencian con los aportes de otros autores. Los problemas que se describen son: educación bancaria, transformación, persuasión y contenido. El analisis de los tres problemas en su contemporaeneidad permite proyectar al pedagogo brasileño como un pensador y activista imprescindible para entender y afrontar algunas de las acuciantes cuestiones que nuestro tiempo plantea. Las ideas de Freire permiten proyectar un hipertexto que guía el izado de las velas del barco de la historia para repensarla y reescribirla.

Evolution of Sialendoscopy in clinical practice: Survey of attending practitioners
Authors: Maharaj Shivesh H , Kana Nadir O , Cassim Zarreen , Mungul Sheetal
Published: May 2022

Sialendoscopy is a relatively new technique that is safe, minimally invasive and effective as a diagnostic as well as a therapeutic tool for the management of deep seated, proximal, salivary ductal obstruction. However, more than 20 years since its inception it is still not in mainstream use worldwide. Objectives Our aim of this study was to ascertain the awareness of sialendoscopy amongst the medical fraternity in South Africa. More specifically, to determine whether it was frequently used amongst practitioners and the type of cases managed using sialendoscopy. Methods An exploratory survey design involving 100 practitioners was used to collect data, using an online survey involving 10 closed-ended multiple choice questions. Results The results of the study revealed that while practitioners saw patients who could benefit from sialendoscopy, most practitioners did not feel comfortable performing the procedure independently, and as such, most patients were referred on to other professionals for management. The majority of attending practitioners believed that they would benefit from further practical and theoretical training in the field of sialendoscopy, illustrating the need for continued professional development in this area.
La chanson française dans les classes de lecture et compréhension de textes en français
Authors: DE OLIVEIRA RAMOS Jozelma
Published: May 2022

Cet article a pour but de partager mon expérience, en tant que professeur de FLE – français langue étrangère – en enseignant la lecture et compréhension de textes en français ; puisque, dans ces classes, l’une de mes stratégies pédagogiques était l’utilisation de la chanson française et francophone. Effectivement, cette stratégie a proportionné aux élèves, au-delà d’une immersion interculturelle, une importante sensibilisation vers l’intérêt d’apprendre d’autres compétences linguistiques de la langue française, telles que la compréhension orale et l’expression orale. Parallèlement, ce processus d’apprentissage, en utilisant les chansons françaises, était aussi un moment d’étude – toujours amusant et ludique – de certains points grammaticaux difficiles à comprendre. Enfin, le moment de partage d’expérience ici proposé discutera comme la chanson, dans les classes de lecture et compréhension de textes en français, peut être un vrai « déclencheur » interculturel pour que les apprenants puissent avancer dans leur apprentissage du FLE.
ПРОТИВОРЕЧИЯ ЭНЕРГЕТИЧЕСКОГО РЫНКА: ОСНОВНАЯ СУТЬ И РАЗВИТИЕ
Authors: Тимонина Виктория Ивановна
Published: May 2022

Цель исследования. За последнее время на мировых энергетических рынках произошли противоречивые трансформации, в которых существуют новые риски и новые возможности. Трансформация придала особый характер процессу глобализации. Появилась возможность реализации производственных процессов с использованием экономических преимуществ по всему миру. Несмотря на развитие альтернативных источников энергии, традиционные виды топлива остаются главными составляющими мирового энергопотребления, ведь неслучайно нефтяная и газовая отрасль оказались в эпицентре геополитического противостояния, стали объектом санкций и ограничений. В статье обсуждаются противоречия энергетического рынка. Также автором проведен анализ причинно-следственных связей.

Методология исследования. В процессе написания статьи были использованы источники, имеющие прямое отношение к этой теме.

Результат исследования. Каждый этап развития энергетики — это особый период возникновения противоречий в энергетике. При этом на её развитие влияют не только сугубо социально-экономические и политические факторы, но и внедрение качественно новых технологий. Иными словами, целесообразно рассматривать развитие энергетики через смену технологических укладов.

Перспективы исследования. В статье анализируются технологические уклады с вытекающими из них противоречиями, которые заставляют нас рассмотреть четвёртый технологический уклад как основной в современной парадигме, и в силу последних событий есть предположение, что общество не перейдёт к «пятому» технологическому укладу в ближайшие 20 лет.
ЭТНОКУЛЬТУРНЫЙ ТУРИЗМ В КОНТЕКСТЕ ФОРМИРОВАНИЯ И РАЗВИТИЯ ПАТРИОТИЗМА
Authors: Дашкова Елена Валерьевна
Published: May 2022

Цель статьи заключается в исследовании этнокультурного туризма в контексте формирования и развития патриотизма в российском обществе.

Результаты исследования. В работе делается вывод о том, что историческая Россия по своим географическим, климатическим, геополитическим и культурным показателям является «идеальной» страной для преимущественного развития именно внутреннего туризма, и данный вид досуговых практик может предоставить людям самые разнообразные программы отдыха, связанные с историко-культурным наследием страны и ее обитателей. Вместе с тем ядро практически любой этнической культуры содержит в себе довольно устойчивые представления, связанные с любовью к собственной Родине, которые далеко не всегда носят политический характер, а обусловлены, например, повышенным вниманием к природе и людям родного края. Этнокультурный туризм занимает существенную роль в процессе патриотического воспитания граждан современной России, что связано с тем, что в его рамках возможно полноценное межэтническое взаимодействие.

Перспективы дальнейшего использования результатов. Актуальность имплементации этнокультурного туризма в процессы патриотического воспитания и его отдельные преимущества заключаются в восприятии окружающего мира в позитивном ключе. При этом с точки зрения философии речь идет о расширении опыта так называемого «своего собственного» на просторы страны (в том числе локации в сельской местности), находящиеся за пределами крупных городов и городских агломераций.
БИОЦЕНТРИЗМ КАК МИРОВОЗЗРЕНЧЕСКАЯ МОДЕЛЬ УСТОЙЧИВОГО РАЗВИТИЯ СОВРЕМЕННОГО ОБЩЕСТВА
Authors: Майснер Татьяна Николаевна
Published: May 2022

Цель исследования заключается в рассмотрении биоцентризма как новой мировоззренческой модели устойчивого развития современного города.

Методологической основой исследования являются аксиологический подход, концепции биоэтики, глубинной экологии, теории коэволюции, теории устойчивого развития города как урбоэкосистемы.

Результаты исследования. Решение экологических проблем современного города возможно только на основе формирования новой мировоззренческой парадигмы, которая бы утверждала гуманистическое отношение к природе. Кризисная ситуация, сложившаяся в последние десятилетия в экологии городской среды, отчасти является следствием доминирования антропоцентрического мировоззрения и потребительской психологии, которые длительное время определяли отношения в системе «человек — природа». Мировоззренческой парадигмой, способной изменить антропоцентристкие установки и потребительскую модель отношения человека к природе, может стать осознанный биоцентризм.

Перспективы исследования. Работа открывает перспективы для дальнейшего исследования ценностных оснований для устойчивого развития урбанистической цивилизации.

Цель исследования состоит в социологическом анализе конструктов маскулинности и феминности в гендерных представлениях современной студенческой молодежи, определении меры соотношения в их (стереотипов) структуре традиционных (инерционных) и эгалитарных (инновационных) гендерных представлений, что позволит судить о скорости и характере социокультурных преобразований в сегодняшнем российском обществе, перспективах его демократизации и модернизации.

Методологическую базу исследования представляют социальный конструкционизм, основные положения структурно-функционального анализа. В работе также использовались общенаучные методы исследования (аналитический, системный, компаративный анализы), методы социологического исследования (анализ материалов, документов; анкетирование и др.) и методы математической статистики.

Результаты исследования. Выявлены существенные трансформации традиционных конструктов маскулинности-феминности в гендерных представлениях современной студенческой молодежи, а также склонность последней к андрогинизму в оценке женских и мужских образов, что отмечено также в ряде работ отечественных исследователей и позволяет констатировать, что в условиях современного российского общества формируется новый тип личности — андрогинный, в котором на паритетных началах представлены сущностные черты как маскулинного, так и феминного типов.

Перспективы исследования. Изучение ценностно-нормативных представлений, гендерных стереотипов современной студенческой молодежи различных типов поселения и профиля образования позволит прогнозировать характер динамики трансформирующегося российского общества, выявить перспективы его модернизации

Corrupción organizacional: Una propuesta de marco teórico
Authors: Morales Inga Sergio , Morales Tristán Oswaldo
Published: May 2022

Diferente de los casos típicos de crimen corporativo, el término corrupción organizacional es empleado por diversos estudios para referir a aquella conducta corrupta cuyo principal beneficiario no es el individuo sino la organización. Mediante una revisión de literatura, este artículo discute los principales mecanismos (socialización, normalización y racionalización) y rasgos (vinculados a elementos organizativos como estructura, liderazgo, ética empresarial, cultura organizacional y cultura nacional) de la corrupción organizacional. Como aporte, esta revisión propone un marco teórico para una comprensión cualitativa de los mecanismos y rasgos que posibilitan la transmisión y evolución de la corrupción organizacional. Asimismo, como finalidad, este artículo señala que una mejor comprensión del fenómeno citado permitirá diseñar políticas anticorrupción mejor adaptadas a su inherente complejidad.
Heterogeneización agroalimentaria y sustentabilidad: complejidades manifiestas para una interpretación en clave organizacional
Authors: Cattaneo Carlos Alberto , Bocchicchio Ana María , Candelino Elizabeth
Published: May 2022

La creciente demanda social por la sustentabilidad de los sistemas agroa- limentarios ha sido una de las razones que ha posibilitado el surgimiento y consolida- ción de nuevas formas de producción, abastecimiento y consumo. Estas modalidades se reflejan en organizaciones que desarrollan diversas estrategias con el fin de integrar a un perfil productivo y comercial uno nuevo que privilegie dicho enfoque. Así, surgen distintas propuestas que buscan articular lógicas diferentes y heterogéneas, si bien al mismo tiempo se revela un conjunto de limitaciones para lograr ese objetivo. Para superarlas, es necesario avanzar hacia una verdadera imbricación de una lógica soste- nible en toda su multidimensionalidad en la estructura y acciones de las organizacio- nes alimentarias. A partir de esta problemática y centrado en las organizaciones que representan estas nuevas modalidades productivas, este trabajo presenta un recorrido a través de los elementos aportados por la teoría socio-organizativa, con el objetivo de construir un marco conceptual que, de manera heurística, contribuya a orientar la investigación empírica de un fenómeno que se asume como complejo. Esta complejidad remite al funcionamiento de una dinámica organizativa renovada (con sus lógicas y aspectos de gestión interna) que debe operar en coordinación con las reglas de gobernanza de todo el sistema agroalimentario, así como con las nuevas demandas sociales.

Method for Analyzing Complex Natural Data and Detecting Anomalies
Authors:   Institute of Cosmophysical Research and Radio Wave Propagation, Far Eastern Branch of the Russian Academy of Sciences, Kamchatka krai, Russian Federation, Mandrikova B. S.
Published: May 2022

A method for analysing natural data of a complex structure based on the use of wavelet data decomposition operations and their combination with threshold functions is proposed. By using adaptive thresholds, operations for noise suppression and detection of anomalous changes in data are built. The implementation operations of the method are described and the application of neutron monitors to data is shown. We used data from the network of ground stations of neutron monitors (www.nmdb.eu), which are secondary cosmic rays. Anomalies in cosmic rays can create a radiation hazard, cause failures in radio communications, as well as defects in the operation of satellites, leading to loss of orientation and destruction. Therefore, the task of timely diagnosis of such events is relevant. The application of the method made it possible to clearly detect and evaluate anomalous changes in cosmic ray data that were observed during disturbed periods in the magnetosphere.
Current State and Prospects of Development of the General Theory of Systems

In the article the approaches to the general theory of systems put by founders of this theory in the sixties of the last century are considered. These approaches are considerably characteristic also of todays submission of the general theory of systems. These approaches can be classified on three conditional groups — mathematical approach to the general theory of systems (M. Mesarovich, Y.

The concept of a regular memory area of an artificial intelligence system defined. Semantic hierarchies are considered as a uniform and universal format for structural descriptions of knowledge representations. An infinite saturated binary tree, the vertices of which are binary sequences, implements a single memory format. Finite saturated binary trees with labeled vertices represent individual knowledge in infinite memory. Regular expressions are used as a specification for the memory areas in question. Regular memory domains generalize the system of morphism domain class developed for semantic hierarchy formalisms. The study of regular memory structures and the choice of special tools for modeling memory and thought processes in artificial intelligence systems carried out. The structure of regular memory is associated with classes of knowledge processing operations, as well as the goals of classifying, storing and applying knowledge of a given structure in such systems. Applications of regular memory structures creates conditions for a deep formalization of the tools of constructing memory structures and modeling thought processes in intelligent systems. Associating regular expressions with state machines allows using them as a parameter for effective modeling of the intelligent processes.

Second law analysis on an elliptical twisted tube for a heat exchanger
Authors: DAGDEVIR Toygun
Published: May 2022

This works presents a second law analysis on a heat exchanger tube configurated as circular smoot tube (CST), elliptical smooth tube (EST) and elliptical twisted tube (ETT) with different aspect ratios and pitch lengths. The ETTs were configurated with different aspect ratio (AR) of 1.5 and 2.0 and twist pitch length (PL) of 50, 100 and 200 mm. The hydraulic diameter was kept as constant for all cases, since the results are influenced by the change in hydraulic diameter. CFD analyzes were run to perform the second law analysis of the considered cases. The analyzes were carried out by considering that the thermo-physical properties of the water fluid change depending on the temperature. Besides, the analyzes were carried out under steady state condition and turbulent flow condition which corresponds to Reynolds number ranging from approximately 4000 to 27,000. The results are evaluated and discussed in terms of the thermal, the frictional and the total entropy generation, the Bejan number, the entropy generation number, the exergy destruction and the second law efficiency. It is resulted that the increase in AR and the decrease in PL for the ETTs show better the second law efficiency. As a result, in the case of ETT_AR=2.0_PL=50 at the minimum mass flow rate considered in the study, the highest second law efficiency is obtained as 0.45, which corresponds to a value greater than 80% in the case of CST.

Energy usually plays a critical role in the development of a country. With the gradual decrease of available traditional fuel reserves and air pollutions problems that being followed by using them, the need to replace alternative renewable and sustainable options to decrease our dependence on fossil fuels has drawn attention. Biomass is a kind of reliable renewable energy that is used to derive combined heat and power systems known as the Organic Rankin Cycle (ORC). This paper presents of exergy analysis of three cycles which have been modeled by EES software for a laundry that needs 32 (kW) power and 2500 (kg/h) 65 (Co) hot water which hot water is our main goal in this study. In RC (gas fuel) and ORC (biomass fuel) power which is produced provides part of electricity needed in the laundry but for Boiler Proving Hot Water (BPHW) the whole electricity needed is bought from the grid. R245fa is a friendly environmentally organic fluid that is used in ORC as a working fluid. The result of this analysis shows for the same conditions the most exergy destruction occurs in the boiler and the least in the pump in three cycles. It also shows the most efficiency of second law respectively is belongs to RC, ORC, BPHW with 0.21%, 0.16%, 9% total efficiency respectively. Moreover, by utilizing EES software and genetic algorithm all of the configurations have been optimized and compared.

Agents that control fertility are termed as antifertility agents or oral contraceptives. Many plant-based products have the antifertility potential which need to be explored.The present study therefore was undertaken to evaluate possible antifertility effects of hydroalcoholic extract of fruits of (HAEMD) and aqueous extract of leaves of (AELS) in experimental rats. Experiments were carried using wistar rats of either sex. Animals were administered with different doses of HAEMD and AELS (250, and 350 mg/kg, p. o) for 30 days. The body weight and reproductive organs weights for male (Testis) and for female (Uterus) were analyzed. Sperm count and Sperm motility was determined in male rats by manually. Testosterone in male and progesterone levels in female rats were checked. Effect of both extracts on Estrous cycle in female rats were checked. Section of testis were taken for histopathological study. The effect of the extract on male rats showed decreased testis weight, reduced sperm count and motility as compared to control animals. The blood testosterone level in male rats was reduced in treatment groups. The testicular histology was altered as compared to control male rats. In female animals, extracts showed antiovulatory activity, alteration in estrous cycle, decreased uterus weight and serum progesterone levels. It is concluded that HAEMD and AELS are effective as antifertility plants for both male and female rats.

Recent estimates show that almost 15% of the Jamaican population is 60 years old or more. About 7% of this population need help with at least one activity of daily living. The demand for long-term care services is expected to rise as the countrys population grows older. In a context in which family sizes are shrinking and older adults are experiencing poor health and critical socioeconomic vulnerability, the means to meet care needs privatelyeither by relying on unpaid care, provided by their families or close networks, or by purchasing services in the marketare scarce. The regulation and provision of long-term care services in the country is highly fragmented and focuses mostly on those that are economically and socially vulnerable, as part of poverty-relief programs. Residential care is the main long-term care service available in Jamaica. Public institutions target the poor, while the private sector also offers various levels of institutional care, from residential to nursing care. The nongovernmental sector is also heavily involved in the provision of residential care in Jamaica, especially through churches. All things considered, women in the family are still the main providers of care. The main conclusion of the report is that long-term care in Jamaica is still an unmet need that requires the development of comprehensive policies and programs.

Published: May 2022

Objective: Hepatic glucose release plays a potential role in hyperglycemia in type 2 diabetes (T2D) patients. The aim of this experimental study was to determine the effect of 6 weeks of high-intensity interval training (HIIT) on fasting levels of glucose and insulin as well as glucokinase (GCK) expression in liver tissue in obese T2D rats.
Materials and Methods: T2D was induced by a high-fat diet (HFD) and streptozotocin (STZ) intraperitoneal injection in 14 male wistar rats, then were randomly divided into HIIT (n=7) and control (n=7) groups. The HIIT group practiced 6-week HIIT (5 days/ weekly). Finally, 48 hours after the last session, fasting levels of glucose, insulin, and GCK expression in liver hepatocytes of both groups were measured and compared by independent T-test (SPSS, Version 22.0).
Results: HIIT resulted in a significant decrease of fasting glucose compared to the control group (P< 0.0001). Compared with the control group, serum insulin (P: 0.018) and GCK expression in hepatocytes (P: 0.030) were significantly increased.
Conclusion: Based on these findings, the improvement in glucose in response to HIIT may be rooted in increased insulin and GCK expression in hepatocytes. However, understanding the mechanisms responsible for the effect of exercise training on the processes affecting hepatic glucose release requires further studies.
