Trabajo social en la dictadura
Authors: Ramírez Marchant Constanza 
Published: May 2021

El trabajo social como disciplina y espacio de resistencia histórica guarda un análisis político y social desde su formación y rápido desarrollo. La dictadura militar instaurada por Augusto Pinochet en Chile, encarnó un recorrido de represión, tortura y clandestinidad para la disciplina, por lo que fue necesario generar nuevas esferas de intervención profesional, lejos de la mirada asesina del gobierno de facto. Los movimientos feministas de la época y el rol de las trabajadoras sociales, se convirtieron en ejes claves para organizar a la comunidad y resistir ante el estado de terror generado por el gobierno de facto. Además de visualizar dicha trinchera de lucha, la disciplina logró construir procesos de resistencia que hoy mantienen en su identidad profesional.

Published: May 2021

Plusieurs recherches rapportent un écart important entre les étudiantes et étudiants autochtones et non autochtones en ce qui a trait à la persévérance scolaire et à l’obtention d’un diplôme qualifiant. Chez les membres de la communauté innue d’Essipit (Québec, Canada) qui poursuivent des études secondaires, collégiales ou universitaires, la situation est toutefois moins problématique. Cet article est le résultat d’une étude qualitative réalisée auprès de neuf jeunes issues de cette communauté et qui persévèrent dans leurs études. Trois questions ont guidé la réalisation de l’étude : 1) Quels sont les facteurs de protection liés à la persévérance scolaire des jeunes de la communauté d’Essipit? 2) Quels sont les motifs qui encouragent les jeunes de cette communauté à poursuivre leurs études? 3) Quelles interventions mises en place dans cette communauté favorisent la persévérance scolaire? Cet article démontre que différents motifs et facteurs de protection influencent positivement la persévérance des jeunes, dont les encouragements et le soutien que ceux-ci reçoivent de leur entourage et des membres de leur communauté, ainsi que les programmes qui leur sont offerts.
Réflexion portant sur une expérience d’adaptation d’un programme en gestion de l’éducation en contexte autochtone offert en ligne
Authors: Deschênes Émilie 
Published: May 2021

Ce texte est issu d’une recherche qualitative et interprétative menée au sein d’une université québécoise et porte sur l’expérience d’adaptation du programme de formation en gestion de l’éducation pour l’offrir dans un contexte autochtone et en ligne. Les objectifs du texte sont : 1) poser un regard sur l’expérience, 2) rapporter des réflexions en lien avec les adaptations et 3) partager les apprentissages et les pratiques prometteuses. Trente-deux (32) personnes participant au projet ont été interrogées. Les résultats proposent que, pour ce type d’adaptation de programme aux milieux autochtones, la pleine collaboration de personnes autochtones soit essentielle, tout comme la sensibilité, la souplesse et les compétences interculturelles des personnes impliquées. Aussi, le rôle de dirigeant est encore en transformation, tout comme l’école autochtone, et un ajustement des pratiques est nécessaire. Notamment faut-il prendre les personnes où elles sont et les accompagner. La formation en ligne a complexifié l’adaptation, mais le succès de l’initiative n’a pas été freiné par cet enjeu. Enfin apparaît la nécessité du codéveloppement pour la prise de décisions et la mise en oeuvre d’actions permettant la décolonisation graduelle des milieux scolaires sur laquelle se poseront des actions d’autochtonisation.

Published: May 2021

Background
Some studies indicate vitamin D’s significant contribution to metabolic processess. Therefore, the purpose of this study was to evaluate the level of carbohydrate and lipid metabolism indices in relation to seasonal changes in 25-hydroxyvitamin D (25(OH)D) concentration in postmenopausal women.

Methods
Sixteen postmenopausal women meeting health criteria and not using vitamin D supplementation were included in the study. Seasonal variation of somatic features and the serum concentration of 25(OH)D, glucose, insulin, parathormon, sclerostin and lipid profile were determined on two terms (autumn-winter).

Results
Comparative analysis of the variables between the study terms revealed a marked decrease in the concentration of 25(OH)D (p ≤ 0.0001), insulin (p < 0.05), insulin resistance index (HOMA-IR), (p < 0.05). The significant positive correlations of changes (Δ) between autumn and winter in 25(OH)D with body mass (p < 0.05), and fat mass (p ≤ 0.01), measured in the first study term, in the group of women with normal body mass index (BMI), and negative correlation with fat mass (p < 0.05) in women with a BMI value above the reference values, were found. The relationship analysis showed that in women with normal BMI, the decrease in 25(OH)D concentrations was greater when the body fat percentage was higher, whereas in women with a BMI value above the reference values, the higher the fat percentage, the smaller was the decrease in 25(OH)D concentration.

Conclusions
Seasonal changes in 25(OH)D concentration did not significantly affect the concentration of carbohydrate and lipid metabolism indices. The magnitude of decline in 25(OH)D levels depends on the fat mass. We suppose that environmental or lifestyle-related factors, e.g., nutritional behaviours, may have had more influence on metabolic indices than changes in 25(OH)D.

Published: May 2021

Aims: To describe a case of hydatidiform mole coexisting with healthy and alive fetus at birth in Mexico.
Presentation of Case: A 35 years old pregnant patient at 18+5 weeks of gestational age and a viable fetus by ultrasound, with atypical pneumonia, plus scant bilateral pleural effusion and partial mole implants on admission to hospital. At week 39 of gestation, the pregnancy was interrupted abdominally; a gestation product was obtained, alive, female, and without malformations. The patient did not present complications. The histopathological report of the placenta was compatible with a partial mole.
Discussion: Gestational trophoblastic disease includes partial hydatidiform mole, its occurrence in coexistence with alive and healthy fetus at birth is 0.005-0.01% respect to the total number of pregnancies. The viability of the term of pregnancy will depend on maternal comorbidities, fetalsss well-being and accessible medical surveillance. The ultrasound is the main diagnostic tool. Clinical monitoring is of vital importance after the end of pregnancy, mainly in mother, due to the risk of developing metastatic disease and recurrence of molar pregnancy.
Conclusion: The case report described is relevant, due to its infrequency. In addition, the imaging findings, emphasizes the importance of a complete and adequate evaluation of the placenta and the fetus, in viable gestation conditions in coexistence with partial mole.

Published: May 2021

This study analyzed Nigeria’s price sector using a formulated model for the price sector of the Nigeria economy. A set of simultaneous equations were used to reflect the implicit gross domestic product deflators for each of the sectors of the Nigeria economy and was found to be over identified under the order condition for identification. The model was estimated by ordinary least square method and two stage least square methods. All the variables have expected signs and as indicated by the F –statistic, the overall performance of the entire regression is significant. The high measure of R2 and Ṝ2, in each case indicates that the explanatory variables included in the equation jointly account for the entire variation. The small RMSE also indicates that the equations have good fit. Durbin –Watson statistics shows that there is no positive first order autocorrelation. The small value of the Theil’s inequality indicates that the equation has good predictive performance. The researcher therefore recommends that government should employ the model so as to be able to monitor price of each of the sectors of the economy and put proper mechanism in place to control those sectors that affect the overall price sector of the economy.

Authors: Alex-Wele M. A. , Obunge O. K. 
Published: May 2021

Aim: Drug resistant tuberculosis is a major challenge in the global bid to control the disease burden and improve treatment outcomes of DRTB infected individuals.
Methods: The Line Probe Assay (LPA) was used to assess the drug resistance pattern and gene mutations in 260 sputum specimens collected consecutively from 260 adult, HIV sero-positive subjects presenting with symptoms suggestive of TB in clinical settings across Rivers State, Nigeria.
Results: The results showed a 61.2% (n = 159) prevalence of TB among all study subjects. LPA analysis showed that 16 (10.1%) were multidrug resistant strains, 17 (10.7%) Rifampicin (RIF) monoresistant strains, 24 (15.1%) Isonaizid (INH) monoresistant strains and 102 (64.2%) drug susceptible strains. Among all 32 RIF-resistant strains, 24 (75%) had a mutation in rpoB S531L at the MUT3 band. Another mutation was observed at rpoB H526D (1/17) in RIF-monoresistant strains but not in MDR-TB strains. In INH resistant strains, mutations were observed at the katG gene [32/39 (82.1%)] which constituted 13/15 (86.7%) in MDR-TB strains and 19/24 (79.2%) in INH-monoresistant strains (p =0.002). Overall frequency of inhA mutation was 6/39 (15.4%); MDR-TB strains [2/15 (13.3%)] and INH-monoresistant strains [4/24 (16.7%), p = 0.2]. Combined KatG and inhA mutation was found in 1/39 (2.6%) of INH-monoresistant strains and in none of MDR-TB strains. Of the single inhA mutation bands, only 1/39 (4.2%) MUT 3B (T8A mutation) was observed in INH-monoresistant strains.
Conclusion: The results showed that drug-resistant TB is prevalent in Rivers State with various gene mutations observed in the different TB strains isolated, making LPA analysis a necessity in the bid to improving prevention and control efforts in the region.

Crop simulation models plays a vital role for estimating the effects of soil, water, nutrients on grain and biomass yields and water productivity of different crops. Among the various crop simulation models, Aqua Crop model was adopted for the predicting the crop water requirement in the Madakasira region, Anantapur district, Andhra Pradesh. The Brinjal crop was selected for the study and was irrigated through two different methods i.e., drip and flood irrigation. The model generated the crop yield and crop water requirement for the drip and flood irrigation of Brinjal crop was compared with the actual field results of crop yield and crop water requirement. The simulated crop yield and crop water requirement for the Brinjal crop under flood irrigation was 5.23 t/ha and 326 mm. The actual crop yield and crop water requirement for the Brinjal crop under flood irrigation was 4.2 t/ha and 335 mm. The simulated crop yield and crop water requirement for the Brinjal crop under Drip irrigation was 5.76 t/ha and 318.3 mm. The actual crop yield and crop water requirement for the Brinjal crop under drip irrigation was 4.8 t/ha and 290 mm. From the results, it was clear that the model simulated the actual conditions of the crop. The benefit cost ratio was done for the experimental field data which clearly shows that the crop yield under drip irrigation has achieved the higher cost benefit ratio. Therefore, Aqua Crop model was suitable for simulating the crop conditions under any circumstances.

Published: May 2021

The present field study was conducted to characterize the blackgram genotypes based on morpho and nutrient content under yellow mosaic virus disease infection. The present investigation was carried out with ten blackgram genotypes (5 known tolerant + 5 known susceptible) in Randomized Block Design (RBD) during summer 2018. Experimental crop was affected by yellow mosaic virus (YMV) naturally at 30 DAS. No management practices were taken for controlling of whitefly population during crop season. Correlation studies were done at 50 DAS which helps to find out the most resistant and most susceptible genotypes among ten backgram genotypes based on leaf pubescence and nutrient content in leaf. Leaf pubescence is one of the most important resistant factors in a number of crops and Minerals, apart from being a vital part of the plant nutrition, may manifest certain maladies in the plants either through disturbing normal metabolism and physiology of the plants or by favouring or by discouraging the plant pathogens, if in excess or otherwise deficient.
Correlation analysis of present field investigation revealed that blackgram genotypes showed strong negative correlation for leaf pubescence, leaf Phosphorous (P) and leaf potassium (K) content with percentage disease index (PDI%) as well as strong positive correlation for leaf Nitrogen (N), leaf Iron (Fe) and leaf Zinc (Zn) content under YMV.

Introduction: Down syndrome is a genetic condition arising from three chromosomal abnormalities, namely trisomy 21 (the most well-known); translocation, and/or mosaicism. This chromosome change occurs in the formation of the fetus, in more detail at the time of cell division, which will characterize the signs and symptoms of the syndrome.
Objective: The purpose of this article is to research the main scientific findings in the last 10 years regarding physical therapy treatments, to verify the best techniques and their respective results, and to address the role of physiotherapy in the development of children with Down syndrome.
Methods: The research only included studies published in the period from 2009 to 2019, systematic review articles and limited the Portuguese and English languages ​​were excluded, excluding all incomplete articles, duplications, abstracts that did not address, and those works that do not have a scientific basis.
Results: In this systematic review, it can be seen that the main research results were disseminated and stored in databases (SciELO, Medline, and LILACS), focusing on the study of and DS patients, specifical children in early childhood. There are few studies on down syndrome in adults. Another important aspect is the concentration of research in the field of sports physiotherapy, few studies have focused on other areas of physiotherapy, such as respiratory, cardiovascular, and cognitive physiotherapy, which go in the opposite direction.
Conclusion: Physiotherapy for patients with DS can improve the quality and life expectancy of these individuals, but the needs of patients with this syndrome involve some physical, physiological and psychological aspects and require the attention of a multidisciplinary team.
Development of a Simpler but Accurate Free Gas Deviation Factor for Fractured (Dual-Porosity) Volumetric Gas Reservoir Fluid
Authors: Alawode A. J. , Falode O. A. 
Published: May 2021

Gas compressibility factor, also known as gas deviation factor or Z-factor, is a thermodynamic correction factor which describes the deviation of a real gas from ideal gas behaviour. The, free gas Z-factor in the Material Balance Equation (MBE) of single-porosity gas reservoirs with insignificant rock (matrix) compaction (after pressure depletion) does not reflect cases in low-permeability gas reservoirs having remarkable rock compaction. Through gas MBE modifications, previous researchers developed Z-factors for dual-porosity (fractured) low permeability gas reservoirs by incorporating gas desorption; however, their approaches create complexity for routine calculations. Therefore this study was designed with the purpose of deriving a free gas Z-factor for single-porosity low-permeability gas reservoirs and further modifying it for more simplicity and accuracy in a dual-porosity scenario. The free gas Z-factor derived for single-porosity low-permeability gas reservoirs is expressed as: where , , , , and are single-porosity Z-factor without rock compaction at pressure , water compressibility, initial water saturation, matrix compressibility, initial gas saturation and pressure depletion, respectively. However, the developed dual porosity free gas Z-factor model incorporates ratio of dual porosity to initial matrix porosity, and it is expressed as: where and are initial matrix porosity and fracture porosity, respectively. The Z-factor model was graphically and statistically correlated with an existing free gas Z-factor model for dual porosity reservoirs. For all the hydraulically fractured shale gas formations considered, the correlations yield R2 values of 1.000.

Published: May 2021

AbstractCarbon dots (CDs), defined by their size of less than 10 nm, are a class of photoluminescent (PL) and electrochemiluminescent (ECL) nanomaterials that include a variety of carbon‐based nanoparticles. However, the control of their properties, especially ECL, remains elusive and afflicted by a series of problems. Here, the authors report CDs that display ECL in water via coreactant ECL, which is the dominant mechanism in biosensing applications. They take advantage of a multicomponent bottom‐up approach for preparing and studying the luminescence properties of CDs doped with a dye acting as PL and ECL probe. The dependence of luminescence properties on the surface chemistry is further reported, by investigating the PL and ECL response of CDs with surfaces rich in primary, methylated, or propylated amino groups. While precursors that contribute to the core characterize the PL emission, the surface states influence the efficiency of the excitation‐dependent PL emission. The ECL emission is influenced by surface states from the organic shell, but states of the core strongly interact with the surface, influencing the ECL efficiency. These findings offer a framework of pre‐ and post‐synthetic design strategies to improve ECL emission properties, opening new opportunities for exploring biosensing applications of CDs.
Dust cloud explosion characteristics and mechanisms in MgH2‐based hydrogen storage materials
Authors: Tsai Yun‐Ting , Huang Guan‐Ting , Zhao Jue‐Quan , Shu Chi‐Min 
Published: May 2021

AbstractThe mechanisms involved in premixed magnesium and hydrogen hybrid and synthetic MgH2 dust cloud explosions were investigated. The results revealed that trace amounts of H2 in Mg explosions can markedly increase explosion severity. Furthermore, H2 addition can weaken the influence of oxygen deficiency on Mg explosion. Moreover, the explosion intensity of synthetic MgH2 was far stronger than that of premixed Mg/H2 mixture or Mg alone because the vacancy defects in Mg and H atoms can form after dehydrogenation of MgH2, which caused that Mg and H2 are prone to oxidation and nitrification in air atmosphere at a low temperature, thereby promoting the explosion. This demonstrates that the explosion risk of MgH2 (even other H2 storage materials) is related to its H2 storage capacity and dehydrogenation temperature. Therefore, for H2 storage materials, the better H2 storage performances can exhibit higher explosion risks.

Published: May 2021

AbstractHypoxia‐inducible factors (HIFs) activate gene transcription in response to reduced O2 availability and play critical roles in development, physiology, and disease pathogenesis. Mutations that dysregulate HIF activity are the genetic basis for tumor predisposition in the von Hippel–Lindau syndrome and excess red blood cell production in hereditary erythrocytosis.

AbstractLittle is known about FOP in Africa and few cases of nonclassic fibrodysplasia ossificans progressiva (FOP) have been reported on the continent. Here we report a three‐year‐old girl from Angola with a nonclassic FOP clinical presentation that is characterized by complex malformations of the toes and fingers, reduction defects of the digits, absence of nails, progressive heterotopic ossification, and a confirmed heterozygous ACVR1 variant at c.983G > A. Emerging knowledge of FOP can serve as a catalyst for increasing awareness of FOP in under‐represented medical communities by achieving a correct FOP diagnosis, improving access of individuals with FOP to clinical trial recruitment, and enhancing the ability of affected individuals to be part of and interact with the international FOP community.
