Published: November 2020

Introduction: Diarrhea still ranks third as the leading cause of death for children under five years. It is estimated that as many as 800,000 deaths under five years were caused by diarrhea in 2010; 11% of the total deaths were under five yearsâ€”about 80% of these deaths occurring in Africa and Southeast Asia.Methods: This manuscript's writing used the literature review method in which a detailed search was carried out on the document in national and international databases.Results and Discussion: The leading cause of diarrhea in children is a virus. The most commonly known virus is Rotavirus (40â€“60%). Viruses that enter through food and drink to enterocytes will cause infection and damage to the small intestine villi. According to WHO, there are five lines of diarrhea management, namely: adequate rehydration, zinc, nutrition, appropriate antibiotics, and education.Conclusion: With good diarrhea management, diarrhea has a good prognosis. Death in sufferers of diarrhea is caused by severe dehydration and secondary malnutrition.Â Â PendahuluanÂ : Diare masih menempati urutan ketiga sebagai penyebab kematian terbanyak untuk anak-anak dibawah lima tahun. Diperkirakan sebanyak 800.000 kematian dibawah lima tahun disebabkan oleh diare pada tahun 2010, yang merupakan 11% dari total kematian dibawah lima tahun. Dengan sekitar 80% kematian ini terjadi di Afrika dan Asia tenggara.Metode: Penulisan naskah ini menggunakan metode tinjauan pustaka dimana dilakukan penelusuran terdahap naskah pada database nasional dan internasional.Hasil dan Diskusi: Penyebab utama diare pada anak oleh virus, virus terbanyak yang diketahui adalah jenis Rotavirus (40â€“60%). Virus dapat masuk kedalam tubuh melaui makanan dan minuman yang dikonsumsi. Setelah sampai sampai ke enterosit, virus akan menimbulkan infeksii dan kerusakan pada villii usus, terutama usus halus. Menurut badan kesehatan dunia (WHO) dipublikaskan lima lintas penatalaksanaan diare, diantaranyai: pemberian carian yang adekuat, pemberian suplement zinc, lanjutkan nutrisi sesuai, pemberian antibiotik bila diperlukan, dan edukasi orang tua.Kesimpulan: Dengan penatalaksanaan diare yang baik, diare memiliki prognosis yang baik. Dominan, angka kematian anak yang mengalami diare disebabkan oleh karena dehidrasi berat serta malnutrisi sekunder yang tidak tertangani dengan baik.

Positive calretinin stain with immunohistochemistry in a 49 year-old female with cardiac myxoma: A case report
Authors: Dewi I Gusti Ayu Sri Mahendra
Published: November 2020

Background: Primary tumors of the heart are scarce. Cardiac myxoma is a primary benign heart tumor most often found with an incidence of 0.5-1.0 cases per million population per year and 90% diagnosed in the fourth to seventh decades of life, rarely found in children. Cardiac myxoma is three times more common in women than in men. These tumors are mostly found in the left atrium.Case description: Female, a 49-year-old patient, came with palpitations, shortness of breath, and weakness since the previous six months. On echocardiography, found a mass in the left atrium suspected of a left atrial myxoma. Surgery was performed, and the specimen was sent for histopathological examination. Macroscopically, the tumor mass shows an irregular shape, brownish color, and spongy consistency. Microscopic examination shows the tumor consisting of proliferation of spindle-shaped and stellate cells, with oval to round nuclei, eosinophilic cytoplasm, mostly scattered, some of which are arranged cord and nest, infiltrative between the myxoid stroma and partially surround small blood vessels to form a vasoformative ring. The specimen also contains the proliferation of blood vessels, extravasation of erythrocytes, and the distribution of inflammatory cells and hemosiderophages. The result of the immunohistochemical examination with calretinin was positive.Conclusion: This case was concluded as cardiac myxoma based on clinical features, echocardiography, macroscopic, routine histopathological, and immunohistochemical examinations.

Introduction: The mortality of severe traumatic brain injury (TBI) is contributed by the severity of the head injury, associated trauma, and complication during treatment. This study aimed to develop a prognostic scoring system of risk factors that contribute to the 14-day mortality of severe TBI.Methods: This was a prospective cohort study including 105 severe TBI patients recruited consecutively from March to October 2016. Multivariate analysis with logistic regression was performed to determine the most contributing risk factors. The validation of prognostic factor was performed with ROC, sensitivity and specificity analysis.Result: There were five significant risk factors of 14-day mortality, which were age > 60 years old (RR: 15.6, 95% CI: 1.88 â€“ 129.95), hypoxia (RR: 17.78, 95% CI: 2.05 â€“ 154.11), GCS 3 â€“ 5 (RR: 34.71, 95% CI: 6.85 â€“ 175.98), effacement of basal cistern (RR: 12.71, 95% CI: 2.61 â€“ 61.95), and traumatic subarachnoid hemorrhage (tSAH) (RR:7.57, 95% CI: 1.19 â€“ 48.36). The prognostic score ranged from 0 to 6 with the best cut-off point of 1. The best predictive AUC with ROC analysis was 0.817, 81.2% of sensitivity, and 75.0% of specificity.Conclusion: The proposed prognostic score has shown good predictive ability.

Published: November 2020

ABSTRACT Objective: to understand the experiences of relatives of critically ill children before bad news report. Method: a phenomenological study based on Heidegger’s philosophical framework. Data collection was carried out from October 2018 to March 2019, through phenomenological interviews with 15 relatives of children hospitalized in a Pediatric Intensive Care Unit. Results: relatives, in their existentiality, experience the facticity thrown into unpredictable situations, regardless of their choices and are faced with feelings of shock, despair and fear before bad news. After emotional impact, especially regarding the possibility of death, relatives reveal hope as a mechanism for coping with the situation. Final considerations: solidarity and sensitivity by health professionals, especially nurses, are essential in understanding the existential dimension of relatives who experience such an experience, understanding the several facets of their existence and offering them opportunities to project themselves.

Relationship between earnings management and abnormal book-tax differences in Brazil
Authors: Morais Henrique Carvalho Bezerra , Macedo Marcelo Alvaro da Silva
Published: November 2020

ABSTRACT The aim of this study was to verify whether the discretionary actions of managers to manage earnings can be captured by abnormal book-tax differences (ABTD). In Brazil, there are no studies with the disaggregated use of earnings management (EM) through operational choices as a proxy for discretionary decisions to be captured by ABTD. Moreover, the previous studies focus on the period before the International Financial Reporting Standards (IFRS) were required in Brazil or when they were still being implemented, which may change the context of earnings management in the country and, consequently, the relationship with ABTD. This study is relevant for accounting information users, such as investors, creditors, the tax authorities, and regulatory bodies, as the findings may help them to identify manager opportunism through earnings management. The identification that tax management can be affected by EM through accounting and operational decisions reveals that investors, creditors, the tax authorities, regulators, and auditors should remain vigilant against deteriorations in accounting information quality and, consequently, in the utility of that information. An analysis of 201 non-financial companies was carried out, covering 2012 to 2016, thus totaling 1,005 observations. Five panel data regression models were used: three to capture EM, one to identify ABTD, and one to relate these variables. A significant and positive relationship was revealed between accounting and operational EM and ABTD, indicating that companies that manage earnings upward have positive ABTD, and companies that manage earnings downward have negative ABTD. This research therefore contributes to identifying that ABTD captures the discretionary actions of managers related to EM through accounting and operational decisions.

RESUMO Este trabalho buscou selecionar cultivares de amendoim resistentes a Spodoptera frugiperda, dos tipos não-preferência para oviposição e alimentação, em testes com e sem chance de escolha. Utilizaram-se cultivares de amendoim de hábitos de crescimento ereto (IAC 5, IAC 8112, IAC 22 e IAC Tatu ST) e rasteiro (IAC 503, IAC 505, IAC 147, IAC 125, IAC Caiapó e IAC Runner 886). Os testes de não-preferência para oviposição foram realizados com adultos recém-emergidos, os quais foram alimentados com solução de mel a 10%, permanecendo nas gaiolas por quatro dias até o início das avaliações. Estas consistiram na quantificação do número de ovos e posturas, com posterior cálculo do número de ovos por postura. Para os testes de não-preferência para alimentação foram colocados discos foliares das cultivares em placas de Petri, liberando uma lagarta de terceiro ínstar por cultivar. Avaliou-se a atratividade a 1, 5, 10, 15, 30, 60, 120, 360, 720; 1.440 minutos, contando-se o número de lagartas que se alimentavam nas cultivares e, ao término do experimento, quantificou-se a área foliar consumida por cultivar. Nos testes de não-preferência para oviposição ou alimentação, com ou sem chance, nenhuma cultivar de hábitos de crescimento ereto ou rasteiro influenciou a oviposição ou alimentação de S. frugiperda. Dessa maneira, as cultivares de amendoim não apresentaram resistência dos tipos não-preferência para oviposição e alimentação.

ABSTRACT Ants are found worldwide playing an important environmental role. Some species are considered as agricultural pests and potential risk to human life and public health acting as pathogens carriers. Ants as Paratrechina longicornis and Camponotus spp. have been found inside hospitals. The aim of this study was the research of mycobacteria in 138 samples of ants (137 Paratrechina longicornis and only one Camponotus spp.) which got into the laboratories of tuberculosis diagnosis. These ants were suspended in sterile saline solution and inoculated into Petragnani and Stonebrink media, incubated at 37° C until 90 days and the isolates were identified as environmental mycobacteria (1 Mycobacterium fortuitum peregrinum, 1 Mycobacterium smegmatis) and 1 Mycobacterium tuberculosis complex. These results showed that ants should also act as mechanical vectors of mycobacteria dissemination in risk environments, reinforcing their significance in public health.

Published: November 2020

Abstract In this work, it was evaluated the phenolic content, redox behavior and antioxidant capacity of several selected teas and tisanes from Brazilian market. The samples were classified as simple (single herb) or composed (blend of two or more herbs). In addition, complementary multivariate statistical approaches were used to identify the correlation and interdependence between the amount of major phytocomponents, such as phenols and flavonoids, as well as the antioxidant activity of the products. Results showed that the total polyphenol and total flavonoid concentrations are correlated to thermodynamic feasibility of reactive oxygen species reduction. The statistical modeling differentiated the results datasets in principal components, whose flavonoid content presented itself as the main parameter to segregate data between simple and composed products. On the other hand, the whole polyphenol content, in both teas and tisanes, was more relevant regarding their antioxidant capacity than the flavonoids content. Considering that the manufactures do not display the real amount of each herb in the labels of the composed products, it was not possible to confirm whether the blends of several species lead to a substantial enhancement on their antioxidant capacity. Furthermore, the redox profile and overall polyphenol content suggest that the consumption of green and black teas as well as traditional yerba mate may be worthwhile in preventing ailments associated with oxidative stress in Brazilian population. Notwithstanding, further clinical studies are required to validate this hypothesis.

ABSTRACT Objective: This prospective study aimed at assessing the effects of anxiety and a follow-up text message on pain perception after the installation of fixed orthodontic appliances and its impact on the patients’ routine. Methods: The sample of this study consisted of 103 orthodontic patients, 40 males and 63 females (mean age 20.5 years), distributed in two groups: G1 (n=51), including control patients that did not receive any post-procedure communication; and G2 (n=52), including patients that received a structured text message. In baseline phase, the patients completed a questionnaire to assess their level of anxiety prior to treatment. Pain was assessed by using 100-mm visual analog scale (VAS) in baseline and ten times prospectively in predetermined time points. VAS was also applied to assess the patient’s routine alterations caused by the pain. All data were analyzed using ANOVA, Tukey, Mann-Whitney, t-test, chi-square and Spearman’s correlation tests. All statistical tests were performed with significance level of 5%. Results: Low-level and high-level anxiety was observed in 42.7% and 7.8% of the patients, respectively. Statistically significant correlation was observed between anxiety and pain (p< 0.05). Maximum mean pain intensity was detected in the second treatment day (G1=36.9mm and G2=26.2mm) and was significantly higher in G1. Nearly 53% of the patients in G1 reported alterations in the routine (18.8mm), while in G2 the percentage rate reached 28.8% (9.9mm) (p=0.013). Conclusions: Anxious patients report more pain after the installation of orthodontic appliances. Text messages were effective to reduce pain levels and to decrease the negative effects on patients’ daily routine.

Abstract: The objective of this work was to quantify the reduction of soybean grain yield caused by Tetranychus urticae damage, and to propose an economic injury level (EIL) for this pest in the crop. The experimental design was set up in randomized complete blocks, with four replicates and a 4x2 factorial arrangement with four levels of mite infestation, with or without mite control. Chlorotic symptoms were evaluated using a damage scale of 1 to 4. Soybean grain yield, number of pods, number of grains, and 1,000-grain weight were quantified for each segment of plant canopy (lower, middle, and upper) and for the whole plants. The chlorophyll content in the leaves was evaluated using the SPAD index. The population density of one two-spotted spider mite per cm2 of leaf area caused the following reductions: one pod per plant, two grains per plant, 0.7 g of 1,000-grain weight, and 0.35 g of grain yield per plant or 42 kg ha-1. Based on the equation y = 4,369 - 41.99x, the EIL of one two-spotted spider mite per cm2 is determined by considering a control cost of US$ 20.00 ha-1 and a soybean crop value of US$ 350.00 Mg-1. As to chlorotic symptoms, the EIL is set between damage scores 1 (no apparent mite damage) and 2 (yellow mottling beginning to appear).

Published: November 2020

The possibility of using a barium-strontium modifier as a gasprotective and refining additive for welding the fluxes based on crushed slag from the production of ferrosilicomanganese is presented. The barium-strontium modifier BSK-2 produced by JSC “NPK Metalltekhnoprom” according to TU 1717-001-75073896–2005 was used as a material for the study. The base of the welding flux was silicomanganese slag produced by the West Siberian Electrometallurgical Plant. The research work on new welding fluxes and flux-additives was carried out using the equipment of the Scientific and Production Center “Welding Processes and Technologies” and the Center for Collective Use “Materials Science”. The use of barium-strontium flux additive was carried out in two ways. In the first option, the flux-additive was made by grinding barium-strontium to a dust-like fraction of less than 0.2 mm with further mixing with liquid sodium glass, drying in a furnace, crushing and separating a fraction of 0.45 – 3.00 mm. In the second option, the flux additive was used in the form of dust with a fraction of less than 0.2 mm. The additives were mixed at a ratio of 2 – 10 % of mass of the slag produced by silicomanganese. Surfacing of the samples was carried out with a welding wire of the sv-08GA grade on a substrate of steel grade 09G2S with a thickness of 20 mm. Quality of the deposited metal was studied, the chemical compositions (deposited layers, slag crusts, the used flux) were investigated by X-ray fluorescence method on XRF-1800 spectrometer and by atomic emission method on DFS-71 spectrometer. The degree of contamination with non-metallic inclusions (non-deforming silicates, point oxides, sulfides) was studied using OLYMPUS GX-51 optical microscope in the magnification range from 100 to 1000. The laboratory studies on the surfacing of steel samples have shown that due to introduction of a flux additive made from barium-strontium modifier, the metal is refined, and the concentration of sulfur and phosphorus decreases. The use of a mixture of a barium-strontium modifier with liquid glass as an additive is preferable to the use of an additive in the form of a dust. It was revealed that the best samples from the point of view of the degree of contamination of the deposited metal with nonmetallic inclusions are samples made using no more than 8 % of barium-strontium flux additive.

The results of molecular phylogenetic studies based on the sequencing of matK gene and trnG-R intergenic spacer of the chloroplast DNA and analysis of the concatenated data of these loci of North Asian representatives of the Cystopteridaceae family are presented. In the genus Gymnocarpium, a dryopteris-clade was distinguished including species without glandular pubescence of fronds – Gymnocarpium dryopteris. Species having glandular pubescent fronds have formed the robertianum-clade (G. robertianum and G. fedtschenkoanum), and 2 subclades, including G. continentale, G. jessoense, and G. tenuipes. In the genus Cystopteris, the analysis confirmed the separation of C. montana from other Cystopteris species, and the separation of C. sudetica from the C. fragilis-complex. This advocate the recognition of monotypic genus Rhizomatopteris including Rh. montana (≡Cystopteris montana), and allows to recognize the section Khokhrjakovia (with C. sudetica) within the genus Cystopteris. This analysis did not allow to separate the species of the type subgenus Cystopteris (C. fragilis-complex) from each other.

Hybridisation in the wild between closely related species is a common mechanism of speciation in the plant kingdom and, in particular, in the grass family. Here we show the usefulness of integrative taxonomy as a tool for revealing hybridisation events in Stipa (one of the largest genera in Poaceae). We demonstrate the usage of the classical morphological approach combining with scanning electron microscopy data, as well as analyses of pollen grains, and the application of molecular techniques including data derived from next generation sequencing. We illustrate the application of this integrative tool by specific examples: (1) in the S. × heptapotamica hybrid complex comprising morphologically distant but genetically closely related species, and (2) in the S. × lazkovii hybrid complex containing genetically distant species.

Açelyalar sahip oldukları etkileyici çiçekleri sayesinde geçmişten günümüze kadar insanların dikkatini çeken önemli süs bitkilerinden olmuştur. Dolayısıyla, bu türün üretilmesi, devamlılığının sağlanması ve nihayetinde özellikle halka açık alanlardaki bitkilendirme alanlarında kullanılması önem arz etmektedir. Vejetatif üretim tekniklerinden biri olan yarı odunsu çelikle üretim tekniği ile sera koşullarında gerçekleştirilen bu çalışmada, köklenmeyi teşvik eden oksin grubu hormonlarından İndol-3-Bütrik Asit (IBA), İndol-3-Asetik Asit (IAA) ve a-Naftalin Asetik Asit (NAA) 1000, 3000 ve 5000 ppm dozlarında, Polystimulin-A6 (POLY) ise 50, 100 ve 150 mg L-1 konsantrasyonlarında hazırlanarak kullanılmıştır. Yarı odunsu çeliklerde elde edilen en yüksek köklenme %67,7 ile POLY 50 mgL-1 işleminde elde edilmiştir. Kontrol uygulamasında %26,7 oranında bir köklenme yüzdesi elde edilmiştir. Açelya çeliklerinin köklenme yüzdelerinin belirlendiği bu araştırmada, oksin grubu hormonları (POLY, NAA ve IAA) kullanılarak yüksek köklenme yüzdesi değerlerinin elde edilmiş olması, bu fitohormonların açelyaların köklenmesinde etkili olduğunu göstermiştir.

Historically, the role of agriculture in our country is quite large, and recently, after some decline, there’s a growing interest tothis segment of the economy. This is usually due to a change in Ukraine’s land policy, with an owner appearing in the land who isinterested in its optimal use. Huge areas of agricultural land are difficult to control due to a lack of accurate maps, anunderdeveloped network of operational monitoring points, ground stations, including meteorological ones, a lack of aviationsupport due to expensive maintenance, and so on. In addition, due to various natural processes, the boundaries of sown areas,soil characteristics and growing conditions in different fields and from plot to plot are constantly changing. All these factorsprevent the receipt of objective operational information necessary to ascertain the current situation, its assessment andforecasting. And without this it is almost impossible to increase agricultural production, optimize land use, forecast the harvest,reduce costs and increase profitability. Abroad, similar problems are successfully solved with the use of data from aerial andspace imagery, as well as the widespread use of satellite navigation during crop and harvest monitoring, to study the state ofvegetation and forecast the productivity of crops.The agricultural sector is one of the most promising industries in Ukraine, for which it is advisable to use remote sensingdata, which provide detailed and necessary information that greatly simplifies the work of research and analysis of agriculturalland productivity. Space images well reflect the boundaries of sown areas, it is possible to track the dynamics of crops, analysisof crop rotation and much more. According to the results of the work, a number of features of automated decoding of agriculturallands were formed.

Authors: El-Yazal Mohamed A. Seif
Published: November 2020

The possibility of improving growth and yield of broad bean (Vicia fabaL.) plants grown in newly cultivated land was conducted during the two successive seasons of 2018 and 2019. For achieving this aim, broad bean plants were fertilized with different rates of organic fertilizers (poultry or farmyard manures) and minerals (NPK). Different growth parameters, chemical constituent and yield were determined in this study. The results indicated that organic fertilized plants achieved higher values of different growth parameters (plant height, number of branches, plant leaf lets blade area and dry weight / plant) and yield and its components (number of pods / plant, no of seeds / pod, weight of seeds / pod, weight of 100 seeds and weight of seeds / plant). The best results were obtained when the plants were fertilized with high rate of poultry manure (8 tons) and NPK fertilizers (50 kg ammonium nitrate 33.5% + 200 kg superphosphate 15.5% + 50 kg potassium Sulphate 48%). The present results also show that the concentration of chlorophyll. A, b, carotenoids, crude proteins, total free amino acids, total carbohydrates, total sugars, reducing sugars an non soluble carbohydrates recorded the higher values in both leaves and seeds of those plants fertilized with either poultry or farmyard manures when compared with those fertilized with NPK. The present study clearly shows that the best effect was recorded by supplying the plants with poultry manure(8 tons + NPK nutrients (50 kg ammonium nitrate 33.5% + 200 kg superphosphate 15.5% + 50 kg potassium Sulphate 48%).

Authors: Mohammed Ibrahim
Published: November 2020

The study evaluated the effect of selected Vinca alkaloids on the microtubule network of CHO cells line and the recovery of its disruption. Model experiments were used for demonstration of the quantification of microtubule network changes induced by Vinca alkaloids using computer-assisted image analysis cells were treated with Vincristine or Vinblastine at various concentrations from 2 μg/l to 800 μg/l for 60 min, or with Vincristine at a concentration of 4615 μg/l and 9230 μg/l for 60 min. Microtubules were detected by means of indirect immunofluorescence. The damage was examined in a fluorescence microscope. Also, cells were treated for 60 min with Vincristine at concentrations of 20 μg/l or 800 μg/l and the recovery process was studied in time intervals of 6, 7, 8, 9, 10h, or 8 and 12h, respectively. Differences in the arrangement of microtubules were assessed by means of a software for quantification of the cytoskeleton changes in cells treated with Vincristine at a concentration of 20 μg/l and in untreated control cells. The microtubule network recovery process in time intervals of 6, 7, 8, 9, and 10h was quantified after treatment with Vincristine at a concentration of 20 μg/l for 60 min using the software for quantification of the cytoskeleton changes.

Published: November 2020

Women undergoing IVF procedures tend to have high levels of estradiol hormone because of the drugs used to stimulate egg production, and this may lead to display cervical cytomorphological changes & may affects pregnancy outcome in IVF cycles. The aim of the study is to correlate serum estradiol level on preovulatory day in women undergoing IVF/ICSI with cytomorphological changes in cervix and pregnancy test result. In this prospective case-control study, a total 100 cases were included 50 case group and 50 control group both in age range between (20-44) First blood sample to test serum estradiol taken on day 2 of menstrual cycle in both groups and second blood sample taken in preovulatory in both case and control group. Serum estradiol measured by Minividas. Cervical pap smear taken in preovulatory day in both case and control groups and stained with conventional pap stain then assessed according to Bethesda system 2001. There is non-significant correlation between serum estradiol in preovulatory day and appearance of abnormality in pap smear reports (P value=0.9). There is non-significant correlation between serum estradiol in preovulatory day and pregnancy test result (P value =0.5). In conclusion, serum estradiol does not have an association with IVF outcome and does not affect pap smear outcome.
Role of expression IL-23 pathway in myocardial injury after global ischemia and reperfusion/cross talk with IL-17
Authors: Ogiku Ling , Fujii Runqiu
Published: November 2020

Myocardial injury caused by global ischemia/reperfusion is a complicated pathophysiological course, in which inflammation is thought to play an important role. Endothelial dysfunction plays a critical role in the pathogenesis of reperfusion injury in the myocardium. This role stems from the close proximity of the endothelium to neutrophils and other inflammatory cell types at the vascular interface during the critical early phase as well as the later phase of reperfusion. IL-17A is a cytokine expressed by a variety of cells in response to inflammatory cytokines that are released following tissue injury and/or inflammation. IL-17A induces epithelial cells to secrete neutrophil chemoattractants. The cytokine IL-23, which can be produced by epithelial cells, plays an important role in IL-17A production. Global myocardial injury induced by abdominal heart transplant model in IL-17A deficient (Il17a-/-), IL-23R deficient (Il23r-/-) and WT mice. Our data showed that cTn-I, neutrophil accumulation MCP-1 and ICAM-1 were significantly less in both Il17a-/- mice and Il23r/- mice than in WT controls. These two pathways may become possible therapeutic targets for the treatment of global ischemia induced myocardial injury.
Parental Human Capital and Adolescents’ Executive Function: Immigrants’ Diminished Returns

Racial minorities, particularly non-Hispanic Blacks (immigrants) in the US, experience weaker effects of family socioeconomic status on tangible outcomes, a pattern called Minorities' Diminished Returns (MDRs). These MDRs are frequently shown for the effects of family SEP on immigrant adolescents' school performance. As a result of these MDRs, immigrant adolescents from high SEP families show worse than expected cognitive outcomes, including but not limited to school performance. However, the existing knowledge is minimal about the role of executive function in explaining diminished returns of family SEP on adolescents’ outcomes. To investigate racial differences in the effects of parental human capital on adolescents’ executive function, we compared non-Hispanic White (non-immigrant) and immigrant adolescents for the effect of parental human capital on adolescents’ executive function. This was a cross-sectional analysis that included 2,723 non-twin non-Hispanic White adolescents from the Adolescent Brain Cognitive Development (ABCD) study. The independent variable was parental human capital (parental educational attainment), treated as a continuous measure with a higher score reflecting higher subjective socioeconomic status. The primary outcome was adolescents’ executive function measured by the stop-signal task (SST). Age, sex, parental marital status, parental employment, family income, and financial difficulties. Immigration status was the effect modifier. Overall, high parental human capital was associated with higher task-based executive function. Immigration status showed statistically significant interactions with parental human capital on adolescents’ executive function outcomes. This interaction term suggested that high parental human capital has a smaller effect on increasing immigrants' executive function than non-immigrant adolescents. The boosting effect of parental human capital on executive function is diminished for immigrants than non-immigrant adolescents. To minimize the inequalities in executive function-related outcomes such as school performance, we need to address the diminishing returns of existing resources for immigrants. Not only should we equalize groups based on their SEP but also equalize the marginal returns of their existing SEP. Such efforts require public policies that aim for equal processes. As such, social policies should address structural and societal barriers such as xenophobia, segregation, racism, and discrimination that hinder immigrant families’ ability to effectively utilize their resources. In a fair society, immigrant and non-immigrant families should be equally able to leverage their SEP resources and turn them into tangible outcomes.

Este trabalho tem como objetivo utilizar o Método dos Caminhos Alternativos de Cargas (MCAC) e os critérios estabelecidos pelo General Services Administration (GSA), a fim de verificar, em um estudo de caso, se as vigas de uma estrutura de concreto armado, dimensionada conforme a NBR 6118 (ABNT, 2014), resistem ao colapso progressivo. Após a análise, as vigas, que possivelmente sofreriam danos, foram redimensionadas para resistir ao colapso. Os resultados indicaram que as vigas têm uma grande probabilidade de sofrer colapso progressivo, apenas com relação aos momentos fletores. Para combater o colapso, observou-se um aumento significativo na área de aço das vigas.
