The abundance of agricultural products often causes environmental problems. The utilization of agricultural waste from carrots can reduce both the feed cost and environmental pollution and become a source of vitamin A for the health of the native chicken. The study aims to analyze carrot (Daucus carota L.) waste juice on native chicken performance. It was conducted from April to July 2019 at Pandu experimental field in North Minahasa Regency. The practical method used was a completely randomized design with four replications. The experimental livestock used in the study was 80-day-old chickens of native chicken. The concentration of carrot juice during the study was as follows: 100% drinking water without carrot juice (W0), 80% water drinking + 20% carrot juice (W1), 60% drinking water + 40% carrot juice (W2), and 20% drinking water + 80% carrot juice (W3). Observed variables included feed intake, body weight gain, feed conversion ratio (FCR), and mortality rate. The results showed that carrot waste juice significantly impacted the body weight gain, feed conversion rate, and 0% mortality rate during the 8 weeks. The concentration of 20% drinking water + 80% carrot juice (W3) with the feed intake ratio of 1.608 g, body weight gain value of 775.63 ± 301  g, and the FCR of 2.1 ± 0.06. However, the consumption ratio did not differ among treatments. The addition of carrot waste juice, as much as 80%, in the drinking water of native chickens showed an increase in body weight compared to other treatments. In conclusion, the current study showed that treatment of carrot waste juice has a significant effect on body weight in 8 weeks of maintenance. Meanwhile, the feed intake ratio of carrot waste juice treatment has no real effect. There was no dead chicken (0%) in the present study. The carrot waste juice can be used in chicken drinks 40–80% by paying attention to the balance of energy content and feed proteins used to grow chickens.

Existential Isolation as a Correlate of Mental Health Problems, Predictor of Treatment Outcome, and Moderator of a Patient-Therapist Match Effect

Published: February 2023

Introduction: Ample research has established that interpersonal isolation—the objective separateness from others—is a correlate of maladaptive psychological outcomes. However, existential isolation (EI)—the feeling of aloneness in one's subjective experience—has received less empirical attention. From the limited existing research, higher EI has been associated with greater severity of mental health concerns and more negative beliefs about treatment. Yet, these investigations have largely been conducted with non-clinical samples. Further, virtually no studies have examined EI as a predictor of current psychotherapy outcomes. Moreover, given their risk of holding negative treatment beliefs, it is plausible that therapy would be most effective if more existentially isolated individuals experienced being well matched to their therapist. This study extended EI research to a clinical sample and provided a novel test of EI as a direct predictor of outcome and moderator of a patient-therapist match system in naturalistic psychotherapy. Method: Data derived from a randomized trial comparing the effectiveness of prospectively matching patients (N = 218) to therapists (N = 48) with empirical strengths in treating the patient's specific presenting problem(s) versus case assignment as usual (Constantino et al., 2021). Patients rated EI at baseline and mental health outcomes repeatedly through treatment. We conducted correlations to examine baseline EI-symptom associations and multilevel modeling to test EI as a predictor of symptom change and moderator of the known beneficial match effect on outcome. Results: As predicted, higher EI was associated with greater depression, anxiety, and distress at baseline, as well as poorer therapy outcome across and at the end of treatment. In the expected direction, though not to a statistically significant level, the positive match effect was stronger for patients with higher versus lower EI. Discussion: We discuss research and practice implications at the intersection of social and clinical psychology.
Evolutionary Medicine
Authors: Beeson Chay , Kosal Erica
Published: February 2023

Evolutionary medicine is a growing area of research and practice; however, it is not widely discussed in introductory biology courses. Because of the interest in human biology, using evolutionary medicine is a great way to hold students’ interest, placing topics in context, making the subject of evolution relevant. Too often students lose interest in learning about evolution because they think it is not pertinent. The pedagogical technique of using case studies in the classroom engages students in a way that will grow their understanding of topics, in this case evolution, as well as helping students with critical thinking and process skills, growing their scientific literacy.

The following case study is appropriate for an introductory biology course that focuses on evolution, an AP biology course, or an introductory evolution course for undergraduates. The case focuses on the evolutionary perspectives of what might be causing human ear infections, as well as the role of beneficial species of gut bacteria in maintaining a healthy immune system. It is advantageous for students to know about natural selection and coevolution before using the case study.

Published: February 2023

Introduction

In our hospital, physicians noticed high free thyroxine (fT4) concentrations without complete suppression of thyroid-stimulating hormone (TSH) in blood samples of patients at the outpatient clinic, which appeared to occur more often following the introduction of a new fT4 immunoassay. This discordance may be explained by incorrect reference intervals, analytical issues, or patient-related factors. We aimed to establish the contribution of the possible factors involved.

Methods

Reference intervals of both fT4 immunoassays were re-evaluated using blood samples of healthy volunteers and the new immunoassay’s performance was assessed using internal quality controls and external quality rounds. The frequency of discordant fT4 and TSH pairings obtained from laboratory requests were retrospectively analysed using a Delfia (n = 3174) and Cobas cohort (n = 3408). Last, a literature search assessed whether the time of blood draw and the time of levothyroxine (L-T4) ingestion may contribute to higher fT4 concentrations in L-T4 users.

Results

The original reference intervals of both fT4 immunoassays were confirmed and no evidence for analytical problems was found. The Delfia (n = 176, 5.5%) and Cobas cohorts (n = 295, 8.7%) showed comparable frequencies of discordance. Interestingly, 72–81% of the discordant results belonged to L-T4 users. Literature indicated the time of blood withdrawal of L-T4 users and, therefore, the time of L-T4 intake as possible explanations.

Conclusions

High fT4 without suppressed TSH concentrations can mainly be explained by L-T4 intake. Physicians and laboratory specialists should be aware of this phenomenon to avoid questioning the assay’s performance or unnecessarily adapting the L-T4 dose in patients.
Effects of plant extract and wood on anatomical structure in ecological environment interaction
Authors: Atılgan Abdi
Published: February 2023

In this study, the impregnation of a 3% solution of a mixture of medicinal aromatic plant extract, borax, and ferula plant extract on wood of eastern spruce (Picea orientalis L. (Link)) and mahogany were carried out and the changes in the anatomical structure of the impregnated wood were determined. Through obtaining extracts of various medicinal aromatic plants (ferula) and dual treatment with borax, the anatomical properties of wood material were examined and the related adhesion scale was determined. The highest retention (retention) was in mahogany wood borax (1.86%), and the lowest retention was again in mahogany wood ferula extract (0.31%). Both wood types demonstrated improved outcomes in comparison to the control sample when the air-dry and fully-dry specific gravity changes were investigated. The maximum air-dried specific gravity value was found in mahogany at 3% borax and ferula + borax (0.56 g/cm3), and the lowest at 3% ferula and borax (0.37 g/cm3). Mahogany wood with 3% borax had the greatest full dry specific gravity value (0.54 g/cm3), and spruce wood with 3% ferula and ferula + borax had the lowest (0.35 g/cm3). There was no retention in the tracheid and trachea cells that perform the transmission function. Because the sapphire cells are the cells that act as storage, adhesion has occurred in these cells.
Inverse Hall-Petch Behavior in Nanocrystalline Aluminum Using Molecular Dynamics
Authors: Melhorance Barboza Alexandre , Rodríguez Aliaga Luis César , Napoleão Bastos Ivan
Published: February 2023

This work investigates the mechanical behavior of nanocrystalline aluminum, with special focus on deformation mechanisms, using molecular dynamics simulations with an interatomic potential parameterized by the authors. To this end, four nanocrystalline samples with grain sizes ranging from 8,2 to 14,2 nm were constructed, each with a volume of 15 x 15 x 20 nm3. As expected, the data from the tensile tests at a strain rate of 1,0 x 109 s−1 showed an inverse Hall-Petch relationship. The work hardening behavior revealed no significant gain in mechanical strength. The dislocation analysis indicated that perfect dislocation density decreases during tensile testing, while the Shockley partials increase. Grain boundary-mediated plasticity was evidenced with atomic diffusion along grain boundaries, as well as by grain rotation. Thus, it is concluded that the conventional plastic deformation mechanisms of metals are not preponderant for nanocrystalline aluminum.
Aqueous Recovery of Zinc and Lead from Coal Fly Ashes of a Colombian Thermoelectric Plant
Authors: Borda Johana , González Claudia , Torres Robinson
Published: February 2023

A hydrometallurgical treatment under ambient conditions was proposed in order to eliminate and recover the lead and zinc contained in a sample of thermal coal fly ash used to produce energy. By using leaching solutions with conventional inorganic acids (HCl, HNO3, and H2SO4), ferric chloride, and sodium citrate, more than 90% zinc and approximately 40% lead were obtained. The most favorable leaching conditions were set at 0,5 M, with a pH value of 8 for citrate. Two leaching stages were necessary to optimize metal recovery: the first with nitric acid for zinc extraction and the second one with citrate for the lead. The sulfur phases of the metals limited a complete metal extraction.

Determining optimal harvest point for champa (Campomanesia lineatifolia R. & P.) fruit based on skin color
Authors: Balaguera-López Helber Enrique , Herrera Arévalo Aníbal
Published: February 2023

Optimal perfume guava fruit harvest point is unknown; fruits are therefore harvested at different ripening stages which reduces product quality. Postharvest quality was assessed in six treatments regarding different fruit ripening stages based on skin colour aimed at determining the optimal harvest point as follows: 100% green (G) being physiologically mature, 25% yellow (Y) 75%G, 50%Y-50%G, 75%Y-25%G, 100%Y and a control (fruit collected from the ground). The fruit was harvested in the municipality of Miraflores (Boyacá, Colombia). At the end of storage it was found that the fruits could be harvested 100%G, being physiologically mature, and had a 7.6-day shelf-life; harvesting riper fruits significantly reduced shelf-life. The same fruits continued to ripen during storage maintaining characteristics such as firmness, weight, total soluble solids and total titratable acidity for a longer time. It could be observed that the fruit's postharvest life became extended by harvesting fruit 100%G; the other treatments ripened normally but their postharvest life was shorter.

Authors: Mejía Osorio Julio César , Rodríguez Baracaldo Rodolfo , Olaya Florez Jhon Jairo
Published: February 2023

This work analyses the effect of alkali treatment on the mechanical properties of banana fibre (Musa Paradisiaca). Fibres were extracted from the pseudostem by a defibring machine; they were mercerised and modified by 5% NaOH (w/v) alkali treatment. Morphological characterisation showed that treated fibres' surface was rougher than that of untreated fibres. Mechanical characterisation indicated that Young's modulus, ultimate tensile strength and strain became decreased by increasing both treated and untreated fibres' diameter.
The impact of topographical characteristics and land use change on the quality of Umbaniun micro-watershed water resources, Meghalaya
Authors: Rymbai Phyllbor , Dey Sudipta , Jha L. K.
Published: February 2023

A watershed is a geohydrological unit draining at a common point. Such natural unit has evolved through rain water interaction with land mass, typically comprising arable land, non-arable land and natural drainage lines in rain-fed areas. Sustainable production depends on the health, vitality and purity of a particular environment in which land and water are important constituents. A pilot study was thus undertaken to study the geomorphology, land-use systems and their impact on water resource management on the Meghalaya Umbaniun micro-watershed. In this Micro-watershed (3951.18 ha), water body covers an area of 5.69ha (0.14%). The paper highlights the linkage between geomorphology, land use systems and its impact on quality of water resources on the Umbaniun Micro-Watershed, Meghalaya. Topographical and physical-chemical characteristics, such as pH, conductivity, dissolved oxygen, turbidity and water temperature, were used as environmental degradation indicators.

Authors: Andrade Pizarro Ricardo , Skurtys Olivier , Osorio Lira Fernando
Published: February 2023

Liquid drop impact on solid surfaces has been well studied due to its wide industrial application; however, there are very few studies of liquid drop impact on vegetable surfaces. The present work determined the drop impact pattern on purple cabbage leaves' surface and evaluated the influence of water drop viscosity and surface tension. The pattern of fluid impact on cabbage surface was evaluated by using a high-speed camera (1250 frames/s) at different impact heights for Weber numbers ranging from 100-800. The results showed that greater maximum spread factor was achieved with higher impact speed and lower surface tension drops. Viscosity had great influence on maximum spread factor and on dynamic impact. Maximum scaled spread factor ξmax was We1/4 for low viscosity water drops (water and Tween20-water). Fluid viscosity could be increased or surface tension decreased to prevent droplet rebound and keep them on purple cabbage surface by spraying them with an edible coating.

Published: February 2023

Linear programming (LP) is one of the most widely-applied techniques in operations research. Many methods have been developed and several others are being proposed for solving LP problems, including the famous simplex method and interior point algorithms. This study was aimed at introducing a new method for solving LP problems. The proposed algorithm starts from an interior point and then carries out orthogonal projections using parametric straight lines to move between the interior and polyhedron frontier defining the feasible region until reaching the extreme optimal point.
A study of shallow water's effect on a ship's pivot point
Authors: Carreño Jorge Enrique , Mora Jaime David , Pérez Francisco Lázaro
Published: February 2023

Information regarding a turning ship's pivot point has been collected, taking practical notes and ship maneuvering manuals into account as well as experimental data and simulated results, together revealing consistent behaviour when varying water depth or some ship's particulars. Results from studies already carried out using the Colombian Navy's River Support Patrol Vessel (RSPV) are included here to estimate the pivot point and contrast results with theory and available observations. Linear manoeuvrability theory was tested and the results revealed poor agreement with kinematic equations. As to the depth variation effect, full-scale experiments confirmed that the pivot point's position, when in shallow water, always varied in the same way, thereby agreeing with available pivot point information.
Manoeuvre test simulation of a teleoperated robot designed for flow measurement in natural water bodies
Authors: Díaz Gutiérrez Carlos Eduardo , Segovia de los Ríos Jose Armando , Garduño Gaffare Mayra P. , Benítez Read Jorge S.
Published: February 2023

This article describes the simulation results of manoeuvring operations used in ships, but applied to an SA-1 teleoperated aquatic robot. The SA-1 is a type of robot designed for flow measurement in natural water bodies (rivers, lakes). A robot's dynamic stability and course stability must be guaranteed due to the different tasks assigned to it. These features can be demonstrated through the pull-out manoeuvre, the Dieudonné spiral manoeuvre, modified Kempf manoeuvre and turning circle manoeuvre. System behaviour when using such manoeuvres can be used to propose a better control system for improving robot performance or modify system design.
Characterising μ-AlTiN coating and assessing its performance during Ti-6Al-4V milling
Authors: Moreno Téllez Carlos Mauricio , Sánchez José Manuel , Higuera Cobos Oscar Fabián
Published: February 2023

This study investigated the mechanical properties and performance of μ-AlTiN coating deposited by PVD cathodic arc technique for a specific Al0, 67Ti0, 33N composition deposited on a WC-Co and AISI D2 steel substrate. The structure of the coating was analysed using SEM, EDAX, XRD, AFM and TEM. Nano indentation measurements were used for analysing mechanical properties; the coating’s performance was evaluated during the milling of a titanium alloy (Ti6Al4V). The TiN film was initially deposited to improve adhesion between coating and substrate, where columnar grains ranging in size from 200 to 500 nm were observed having NaCl-type structure. μ-AlTiN grain growth was also columnar but had ~50 nm grain size. The μ-AlTiN coated tool life was compared to an uncoated tool to determine the coating’s influence during Ti6Al4V milling. The μ-AlTiN coating improved tool life by 100% compared to that of an uncoated tool due to aluminium oxide and TiC formation on the surface and a decrease in friction coefficient between the chip and the tool.

Authors: García Ubaque César Augusto , González Hässig Andrés , Vaca Bohórquez Martha Lucía
Published: February 2023

This paper presents analytical data from tests on bricks made from different clay/ash mixtures. The ashes used were obtained from a Hoffmann-type brick-making furnace equipped for coal and municipal solid waste co-firing. The bricks were physically and chemically characterised and their quality was determined by porosimetry, water absorption, breaking load and tensile strength tests. Brick loading capacity increased by up to 10% with ash mixtures and decreased at higher percentages, whereas water absorption increased brick loading capacity for all mixtures. This study showed that clay/ash bricks complied with all the quality standards required in Colombia.

Authors: Kunst Sandra Raquel , Ludwig Gustavo Alberto , Ortega Vega María Rita , De Fraga Malfatti Célia
Published: February 2023

This study was aimed at coating galvanised steel with a hybrid film obtained from a sol consisting of silane precursors 3 - (trimetoxisililpropil) methacrylate (TMSPMA) and tetraethoxysilane (TEOS). The pH of the hydrolysed-silane solution was 1 and 3. The influence of adding corrosion inhibitor (i.e. 0.01M cerium nitrate) was evaluated for all samples. The hybrid films were deposited by dip-coating. The film was characterised scanning electron microscopy (SEM), profilometry, contact angle measurement, potentiodynamic polarisation and electrochemical impedance spectroscopy. The results showed that solution pH influenced hybrid film formation and final surface properties. Additionally, cerium nitrate as corrosion inhibitor addition enhances corrosion resistance of the films.
Zeolite LTA synthesis: Optimising synthesis conditions by using the modified sequential simplex method
Authors: García Soto Andrés Ricardo , Rodríguez Niño Gerardo , Trujillo Carlos Alexander
Published: February 2023

This paper presents research concerning the simultaneous effect of the most influential synthesis variables in the preparation of Zeolite LTA. The simplex method was used for ascertaining optimal synthesis conditions, where the relative crystallinity (regarding a commercial sample) of synthesised zeolite was defined as response function. Crystallinity was measured by X-ray diffraction. Optimum conditions were found after 24 trials, giving 95.4% relative crystallinity and Na2O/SiO2=2.58, SiO2/Al2O3=1.45 and H2O/Na2O=46.92 molar ratios; 11.7 h crystal growth time, 6.1 h crystallisation time (reaction) and 78oC reaction temperature were found to be optimal synthesis conditions. A computer programme for simulating a zeolite phase diagram was designed to verify whether the molar ratios indicated by the optimisation algorithm were leading to the desired zeolite type. The results were compared to those in previous work where the fixed factor method was used.
Towards a systemic assessment of environmental impact (SAEI) regarding alternative hydrosedimentological management practice in the Canal del Dique, Colombia
Authors: Vega Mora Leonel , Ordoñez Jaime Iván , Pinilla Agudelo Gabriel Antonio
Published: February 2023

The Canal del Dique, located on the Colombian Caribbean Coast, can be seen as an "artificial" branch of the River Magdalena. Since its inception in 1650, it has undergone a series of interventions aimed at optimising river navigation between Cartagena and the interior of the country, little consideration having been paid to institutional, economic, social and environmental impacts. This paper presents a systemic assessment of environmental impact (SAEI) methodology, based on systemic parameterisation of the environment, proposed by Vega [2011], for the strategic environmental assessment of policy, plans, programmes or large-scale projects, considering a case study of the Canal del Dique environmental rehabilitation as proposed by the Colombian government. Information arising from the framework of an inter-administrative agreement between the Universidad Nacional de Colombia and the Regional Autonomous Corporation for the Rio Grande de la Magdalena (CORMAGDALENA) was used for studying the environmental restoration of and navigation in the Canal del Dique [UN-LEH, 2008]. The authors developed and summarised SAEI regarding six alternatives for hydrosedimentological management in the canal to obtain results concerning environmental impairment or improvement regarding each factor considered, and the degree of aggressiveness or betterment involved in each alternative. Alternative 4, an enhanced version of current condition (ECC) would have produced the greatest environmental benefit (i.e. limited dredging plus optimising channel-wetland interconnection) requiring the narrowing of three straight reaches along the canal and the construction of a sluice-gate system in the Strait of Paracuica (near the town of El Recreo).
How to assess responsible digital citizenship? Economics students in the digital world
Authors: Görög Vivien , Udvari Beáta
Published: February 2023

The 21st century is characterized by digital transformation, which affects economic processes and social life, and results in the parallel existence of life in both online and offline spheres. Thus, the concept of citizenship should no longer be restricted to its traditional understanding, but expanded to digital citizenship as well, and it should be adapted to the challenges of the 21st century. Thus, we need to analyze responsible digital citizenship, and our research is aimed at the question of how to assess this. As a pilot, we conducted a survey among university students to understand the focal points in this field. Our results confirm that most students can be considered responsible digital citizens, and can also be classified according to various aspects of responsible digital citizenship.
Nature of Human Rights Violation on Female Garments Workers in Bangladesh
Authors: Basirulla MD. , Tasnim Farhat
Published: February 2023

Bangladesh, a fast-growing developing country, has been experiencing rapid development in export-oriented industrialization. The total contribution of the garment industries to the national foreign exchange earnings is around 83%. About 80% of garment workers are women, and most have migrated from rural areas to industrial cities. Female workers have been an important factor in the growth of the garment industry in Bangladesh. Despite its contribution to the national economy and employment opportunities, the garment industry in Bangladesh is beset by many grievances. Such as sexual harassment, health problems, lack of toilet facilities, exploitation of low-paid and overworked workers and large-scale social insecurity. The present research analyzed such violations from different aspects with a qualitative approach, The main objective of this paper is to find out the types and nature of human rights violations that occur against female garment workers in Bangladesh. The present research combines both exploratory and descriptive methods. Sampled garment workers from two selected factories were surveyed and interviewed to understand the practical situation at the field level. The data findings have provided a complete picture of the nature of the human rights violations that occurred. The human rights of women workers have been found to be violated from all nine indicators. The patriarchal socio-economic setting and economic vulnerability of the women and their lack of awareness, as well as reluctance and quick profit motive of the factory owners, have contributed most to such unwanted situations.

It is commonly supposed the first Russian Old Testament Translation was made by Gerasim Pavskij during the work of Russian Bible Society. But Fotinskij’s translation is earlier one. This translation hasn’t been described, studied and published before. In the article main peculiarities of the translation are described. It is the new-type translation which breaks off with the tradition of Church Slavonic translations. The purpose of the translation is interpretation of Judaic exegesis, and the method is literal. Additionally, translator’s stylistic conception is examined. The language of the translation is characterized as a variant of the Russian language by XVIII–XIX centuries with archaic, vernacular and Ukrainian elements.
Bośnia i Hercegowina w życiu Adama Stefana Sapiehy
Authors: Lis Tomasz Jacek
Published: February 2023

Krakow priest Adam Stefan Sapieha, like his father Adam Stanislaw, was interested in the southern Slavs. As a young boy he accompanied in journeys that “Red Prince” took place on the Balkan Peninsula. Also, as an adult, he held expeditions to the south. One of them took place in 1896. When Adam Stefan was in Croatia, he decided to visit the neighboring Bosnia and Herzegovina. Historians believe that he was helping the Poles in Bosnia. They also claim that in 1912 he was the initiator of the mission to Bosnia and Herzegovina. In my article, I would like slightly modify so far posed thesis, because sources analysis shows that the reality was different than it was presented in the past by Polish historiography.

El estudio de las trayectorias escolares permite observar el comportamiento académico de los estudiantes a lo largo de su formación, desde el ingreso hasta la conclusión de los estudios de licenciatura, en el contexto de una institución superior con un plan de estudios determinado. El objetivo de esta investigación fue caracterizar las trayectorias escolares de una muestra de alumnos de la cohorte 2017 de la licenciatura en Psicología en una universidad pública. A través de una convocatoria abierta a los estudiantes de dicha generación, se conformó una muestra de 17 escolares. Se realizó un estudio cuantitativo descriptivo, mediante el análisis de una base de datos que se construyó a partir de la consulta de la plataforma de la Dirección General de Administración Escolar (DGAE) y del Sistema Integral de Administración Escolar (SIAE) (http//:www.dgae.unam.mx) de la Universidad Nacional Autónoma de México, organizada en 198 variables y 691 casos, con la que se realizó el análisis estadístico en el programa SPSS-20. Las variables analizadas fueron: sexo, promedio de bachillerato, escuela de procedencia, calificaciones en cada una de las 52 asignaturas, ciclo y tipo de examen. Los resultados mostraron que los alumnos cursaron los ciclos académicos de acuerdo con los criterios del plan de estudios y el nivel de avance fue el esperado, con promedio de calificación de 8 y superior, logrando el 100% de créditos del plan de estudios. No obstante, no se puede concluir si ocurrió algún efecto por la modificación curricular.

Las consecuencias negativas que ha dejado a su paso la pandemia se han sentido en todo el mundo y en todos los ámbitos de la actividad humana. El sector educativo ha sido uno de los más golpeados, y uno de los aspectos que más se tornó fundamental tanto por su relevancia como por su ausencia, fue la capacidad estudiantil para aprender por cuenta propia. Considerada esta capacidad como desempeño autodidacta, el presente trabajo tuvo como objetivo identificar la relación entre dicho desempeño y el desempeño docente, en particular el didáctico en el nivel educativo superior. El método que se empleó fue usar como punto de partida un análisis lógico y funcional de las relaciones necesarias para el aprendizaje por cuenta del propio estudiante, empleando como base la categoría teórica de interacción didáctica. A partir de esto, se enuncian condiciones y factores encontrados que posibilitan su emergencia en términos de lo que corresponde al docente y al estudiante llevar a cabo. Para concluir, a la luz de esta perspectiva y del análisis hecho, se describe la relevancia del mencionado desempeño en la conformación de capacidades complejas, desempeños profesionales y condiciones adversas como lo es un confinamiento.

Las estrategias de aprendizaje son fundamentales para guiar el proceso formativo y mejorar el desempeño académico de los estudiantes. En ese sentido, el propósito investigativo fue diseñar una estrategia de aprendizaje para fortalecer el rendimiento académico numérico variacional, bajo las fases Van Hiele. El problema de bajo desempeño matemático por dificultades en competencias numérico variacionales permitió preguntar ¿Qué estrategia de aprendizaje (TIC) fortalece el rendimiento académico del componente numérico variacional? Para responder a la cuestión, se adelantó un estudio inductivo, de investigación aplicada, cualitativa, no experimental, fenomenológico-hermenéutico, con docentes de matemáticas de segundo a cuarto grado, quienes participaron en una entrevista semiestructurada, y con estudiantes de quinto grado, que participaron en la estrategia desarrollando un diario de campo. Se concluye que, para diseñar estrategias de aprendizaje que fortalezcan el rendimiento académico del componente numérico variacional, bajo fases Van Hiele, se deben considerar la introducción, la vinculación al currículo, las actividades de enseñanza y de evaluación con los niveles Van Hiele: 1) información, 2) orientación dirigida, 3) explicitación y 4) orientación libre. Permitiendo, la motivación y desarrollo de aprendizajes autorregulados del estudiante, procesos académicos asertivos, secuenciales, coherentes y dinámicos.

O artigo tem o objetivo de analisar as dimensões e regimes da regulação enquanto produção social na Rede de Atenção às Urgências e Emergências (RUE) em duas regiões de saúde. Trata-se de um estudo de casos múltiplos, de caráter qualitativo, realizado por meio de 61 entrevistas com gestores, usuários e gerentes de serviços de saúde. A análise teve como referencial teórico a Teoria da Produção Social. Foram identificados os regimes de regulação profissional, leiga, clientelista e governamental, nas dimensões sistêmica, dos serviços e de acesso. Os principais resultados apontam para fluxos de regulação produzidos por movimentos de diversos atores sociais, com destaque para a ação de representantes de prestadores de serviços hospitalares, sobretudo privados, caracterizando a proposta de um outro regime: a regulação mercantil. Os limites e potências de arranjos como as centrais de regulação hospitalares e do Serviço de Atendimento Móvel de Urgência (SAMU), os núcleos internos de regulação hospitalar e o uso do WhatsApp são evidenciados. A regulação em saúde na RUE é constituída por processos sociais complexos, contraditórios e conflitantes, cujos fluxos são produzidos no limite entre o interesse público e o privado.

RESUMO Este trabalho avaliou o comportamento de fratura da liga de alumínio AA7075-T6 submetida a carregamento de fadiga. Ambos os corpos de prova entalhados e não entalhados foram submetidos a um tratamento térmico de retrogression and re-aging (RRA) e nitretação a plasma antes dos ensaios mecânicos. A nitretação a plasma, que tem sido um método escolhido para aumentar a dureza superficial e as resistências à fadiga, desgaste e corrosão de diversas ligas, foi realizada com tela ativa com fonte DC de 20 Hz e ciclo de trabalho de 40 Hz. O tratamento RRA, que é utilizado para aumentar a resistência e a dureza da liga de alumínio AA7075 e obter melhorias nos comportamentos de fadiga e corrosão, foi realizado a 200 °C por 20 minutos com resfriamento a água (resolubilização), seguido de 24 horas a 120 °C (reenvelhecimento). Os ensaios de fadiga axial de corpos de prova entalhados e não entalhados foram realizados com R = 0,1, frequência de 14 Hz, e em nível de tensão de 150 MPa para corpos de prova entalhados e 500 MPa para corpos de prova não entalhados. A fratura por fadiga foi então realizada via estereomicroscopia e microscopia eletrônica de varredura. Para os corpos de prova não entalhados, as condições AA7075-T6 e AA7075-RRA apresentaram características de fratura semelhantes, com boa definição dos três estágios de falha por fadiga; a condição nitretada AA7075 não apresentou evidência de fratura por fadiga típica. Os corpos de prova entalhados apresentaram fractografias semelhantes à condição de concentração de tensão severa, com marcas superficiais convexas à região de nucleação.

Abstract Studies have shown that carbon tetrachloride (CCl4) induces hepatic and renal damage arising from oxidative stress. The present study was undertaken to examine the effect of omega-3 fatty acids and/or soya isoflavones on CCl4 induced toxicity in male albino rat liver and kidney. For this purpose, 42 rats were divided as follows: group 1, rats serves as the control without any treatment; group 2, rats were administered a single dose of CCl4 intraperitoneally (1 mg/kg b. wt.); group 3, rats were supplemented daily with omega-300 orally (400 mg/kg b. wt.); group 4, rats were supplemented daily with pro-S orally (50 mg/kg b. wt.); group 5, rats were supplemented daily with omega-300 orally for four weeks, then after 24 hours treated with a single dose of CCl4 at the same tested doses. group 6, rats were supplemented daily with pro- S orally for four weeks, then after 24 hours treated with a single dose of CCl4 at the same tested doses; group 7, rats were supplemented daily with an oral combination of omega-300 and pro-S orally for four weeks, then after 24 hours treated with a single dose of CCl4 at the same tested doses. Results showed that CCl4 administration induces hepatic damage indicated by a significant increase in the activities of alkaline phosphatase (ALP), aspartate aminotransferase (AST) and Aalanine aminotransferase (ALT) enzymes and glucose level, with a significant increase in malondialdehyde (MDA) and nitric oxide (NO) levels and a significant decrease of reduced glutathione (GSH) level in liver tissue. Also, CCl4 toxicity induce renal damage manifested in a significant increase in serum urea, creatinine, uric acid, and oxidative stress of kidney tissue reflected by increase of MDA, NO and the decrease of GSH levels. The pre-treatment with omega-3 fatty acids and/or soya isoflavones revealed ameliorative effect against deleterious effects of CCl4 toxicity on hepatic and renal tissues and all tested parameters. Results of the current study revealed also that the pre-treatment with omega-3 fatty acids and/or soya isoflavones to rats improved liver and kidney function and produced high antioxidant activity.
