Dentro de las plagas que afectan al cultivo de aguacate encontramos Oligonychus perseae o mejor conocida como araña cristalina. Este ácaro produce afectaciones en la epidermis de las hojas decolorando las áreas lesionadas, en ataques severos causan defoliación y baja producción, todo esto a consecuencia de la extracción del contenido celular de los tejidos. En el Estado de México, existen cerca de 10 000 ha plantadas con aguacate, con una producción promedio de 15.602 t ha-1. Se determinó la distribución espacial de O. perseae en cuatro municipios productores de aguacate var. Hass mediante la aplicación de análisis geoestadístico y el krigeado ordinario. Los resultados muestran que las poblaciones de araña cristalina se presentan de manera agregada ajustándose a modelos esféricos en su mayoría. La superficie infestada con el ácaro superó 73% del municipio en todos los muestreos y el número máximo de individuos encontrados fue de 1 445 organismos por árbol. Los municipios más afectados fueron Coatepec Harinas y Donato Guerra.

México es el centro de origen y domesticación del maíz (Zea mays L.), en algunas regiones aún existen poblaciones criollas con potencial para generar variedades mejoradas. El objetivo de este estudio fue evaluar el comportamiento agronómico y fisiológico de doce poblaciones de maíz nativas del sureste de México. El experimento se realizó en Tizimín, Yucatán en el año 2017. Se evaluaron 32 parámetros correspondientes a variables vegetativas, fenológicas, agronómicas y fisiológicas. Los resultados mostraron una diferencia de 75 cm entre las plantas más bajas (Xn-69) y las de porte más alto (CNB), las plantas de la población DZ-252 presentaron mayor follaje (19.1 hojas) y mayor diámetro de tallo (26 mm), las poblaciones más precoces fueron CM y CCB (65.5 y 65.8 días, respectivamente). El 58% de las poblaciones evaluadas superó el rendimiento promedio de la región (4.5 t ha-1). El mayor rendimiento lo obtuvieron las poblaciones CM, Cro, H1 y SP2015 (117.7, 105.8, 111.5 y 109.5 g planta-1, respectivamente). Las poblaciones CM, DZ2015, Cja y Cro tuvieron mayor tasa fotosintética; sin embargo, la mayor eficiencia del uso del agua lo presentaron las poblaciones DZ-252 y XnQroo (8.9 μmol CO2/mmol H2O). La población CM destacó por su rendimiento y precocidad, la DZ-252 podría utilizarse como forraje por la cantidad de biomasa que generó y la XnQroo debería ser estudiada bajo condiciones de restricción hídrica por su eficiencia del uso del agua, estas tres poblaciones deberían incluirse en programas de mejoramiento genético.

Published: September 2019

Ante a possibilidade do uso de águas com restrições quanto à salinidade e de fertilizantes alternativos na produção de hortaliças, esta pesquisa objetivou avaliar os componentes de crescimento e a produção de diferentes cultivares de alfaces quando cultivadas sob condições de salinidade hídrica em substratos, com e sem aplicação de urina de vaca. O experimento foi conduzido em delineamento inteiramente casualizado, em arranjo fatorial 4 x 2 x 2, correspondentes a quatro cultivares de alfaces crespas (Mônica, Veneranda, Scarlet e Rosabela), duas concentrações de urina de vaca (0,0 e 2,5%) e dois níveis de condutividade elétrica da água de irrigação (0,2 e 3,0 dS m-1), com três repetições e três plantas por parcela. A salinidade da água de irrigação reduziu o crescimento em altura das cultivares Mônica, Scalet e Rosabela. O uso da urina de vaca foi mais eficiente no número de folhas comerciais da cultivar de alface roxa Scarlet. Com exceção da cultivar Veneranda, o estresse salino reduziu o número de folhas comerciais das cultivares de alface. O estresse salino promoveu depleção na circunferência da cabeça das cultivares de alface, independentemente do uso de urina de vaca até 2,5% de concentração. A elevação da salinidade da água de irrigação a 3,0 dS m-1 reduziu a área foliar nas alfaces não fertilizadas com urina de vaca. A cultivar de alface Veneranda apresentou maior massa fresca da parte aérea e produtividade, independentemente das condições de salinidade hídrica e uso de urina de vaca.

Published: September 2019

Introduction. The activities of health workers are associated with the impact of many harmful factors that lead to loss of health. Compared with other professional groups, health care workers are ill longer and harder, which may be due to polymorbidity pathology.

The aim of the study based on the survey data to study the representation of health workers about working conditions and to identify their impact on the formation of occupational diseases.

Materials and methods. In order to get a real idea of the attitude of medical workers to their working conditions in 2018, an anonymous survey was conducted of 1129 doctors and 776 employees of secondary and junior medical personnel working in health care institutions in St. Petersburg, Moscow, Krasnoyarsk, Vologda and Orel.

Results. Research of working conditions and health of physicians allowed to establish that work in medical institutions imposes considerable requirements to an organism of working, its physical condition and endurance, volume of operational and long-term memory, ability to resist to mental, moral and ethical overloads.

Conclusions: The most important method of combating the development of occupational diseases is their prevention. Organizational and preventive measures should be aimed primarily at monitoring the working conditions and health of medical staff .

Published: September 2019

Introduction.The modern stage of development of electronics is characterized by the widespread use of integrated circuits (IC). Assessment of working conditions in a promising, developing production of electronic components with hygienic positions is an urgent task.

The aim of the studyis to conduct a hygienic assessment of working conditions of workers in the main professions in the production of IC.

Materials and methods.Hygienic research conducted at three modern enterprises for the production of chips and semiconductor devices, included the study of the conditions and nature of work of workers in the main professions. 215 chemical analyses for the content of harmful substances were carried out in order to assess the air environment and 270 measurements of the levels of physical factors at 18 workplaces.

Results.Findings of hygienic assessment of working conditions for employees engaged in manufacture of microcircuits: operators of chemical processing, precision photolithography (PPL), diffusion processes, vacuum deposition, and IMC assemblers are reported. Based on the analysis of the technological process and the list of materials used and time-study data, the studies of workplace air pollution, sound levels, artificial lighting, microclimate parameters (temperature, humidity, air velocity), working process parameters were carried out. The jobs in which work is characterized by toxic chemicals exposure, precision visual operations using optical instruments during 55% of the shift were singled out. Priority occupational health risk factors for workers employed in modern IMC production and main areas of working environment optimization were revealed.

Conclusions.Based on the conducted hygienic studies, musculoskeletal system load combined with visual strain were found to bethe priority occupational health risk factors for microcircuit production workers.Manual operations taking up a significant part of the working process and introduction of automated IMC technological processesbeing insufficient, preventive measures should be aimed at organizing a rational working regime that provides reducing of visual strainand musculoskeletal system load.
Does visual scanpath reflect self-focused and other-focused attention, a maintenance factor of social anxiety?
Authors: Tomita Nozomi , Ayumi Minamide , Kumano Hiroaki
Published: September 2019

Social anxiety disorder has two
critical attentional processes, self-focused attention (SFA) and other-focused
attention (OFA). These biases are caused by two
psychological aspects: Strategies known as positive metacognitive beliefs and negative
metacognitive beliefs. A method
in which the occurrence of OFA is predicted by eye movement has been proposed.
However, few studies have investigated the relationship between SFA and changes
of eye movement. The relationship between the degree of SFA and OFA during speech and eye movements was investigated in this study, based on the psychosomatic relationship in which eye movements reflect psychological changes.
Anti-politics of the Heterodox Poetry and Life history of Shah Abdul Latif: Ambedkarian Perspective
Authors: Hussain Ghulam
Published: September 2019

This paper is an attempt to analyze from the Ambedkarian perspective the interpretation of Latif’s poetry by the Progressives to assess its emancipatory potential for the Dalits. Building my critique primarily on the scholarly work of H.T.Sorley, I argue that in an attempt to construct the Sufi image of ‘Sindhi nation’, the Progressives undermine the casteist, fatalist and sectarian import of Latif’s poetry and life-history. Latif’s heterodox and multivocal nature of poetry and ambiguity regarding the originality of his verses gives expression to multiple and contradictory signifiers, including the casteist ones. This heterodoxy of Latif creates the anti-political crises of interpretations and self-contradictory projections that depoliticizes the problem of casteism. It allows the ‘Progressives’, like any other social and political group, to legitimize and popularize the selective verses that may have, at least on surface, the egalitarian and patriotic import, to exonerate Latif from any possible hegemonic impact of the orthodox casteist values and the Ashrafia privileges that he enjoyed during his lifetime, or the Ashrafia-Savarna Progressives themselves continue to enjoy.

Thinking through prior bodies: autonomic uncertainty and interoceptive self-inference
Authors: Allen Micah , Legrand Nicolas , Correa Camile Maria Costa , Fardo Francesca
Published: September 2019

The Bayesian Brain Hypothesis, as formalized by the Free Energy Principal, is ascendant in the cognitive sciences. But how does the Bayesian Brain obtain prior beliefs? Veissière and colleagues argue that sociocultural interaction is one important source. We offer a complementary model in which “interoceptive self-inference” guides the estimation of expected uncertainty both in ourselves and in our social conspecifics.
Functional connectivity predicts the dispositional use of expressive suppression but not cognitive reappraisal

Published: September 2019

Previous research has identified specific brain regions associated with regulating emotion using common strategies such as expressive suppression and cognitive reappraisal. However, most research focuses on a priori regions and directs participants how to regulate, which may not reflect how people naturally regulate outside the laboratory. Here, we used a data-driven approach to investigate how individual differences in distributed intrinsic functional brain connectivity predict emotion regulation tendency. Specifically, we used connectome-based predictive modeling to extract functional connections in the brain significantly related to the dispositional use of suppression and reappraisal. These edges were then used in a predictive model and cross-validated in novel participants to identify a neural signature that reflects individual differences in the tendency to suppress and reappraise emotion. We found a significant neural signature for the dispositional use of suppression, but not reappraisal. Within this whole-brain signature, the intrinsic connectivity of the default mode network was most informative of suppression tendency. In addition, the predictive performance of this model was significant in males, but not females. These findings help inform how whole-brain networks of functional connectivity characterize how people tend to regulate emotion outside the laboratory.
Individual response to antidepressants for depression in adults – a simulation study and meta-analysis
Authors: Munkholm Klaus , Homan Stephanie , Homan Philipp
Published: September 2019

Background. The observation that some patients appear to respond better to antidepressants for depression than others encourages the assumption that the effect of antidepressants differs between individuals and that treatment can be personalized. To test this assumption, we compared the outcome variance in the group of patients receiving antidepressants with the outcome variance of the group of patients receiving placebo in randomized controlled trials (RCTs) of adults with major depressive disorder (MDD). An increased variance in the antidepressant group would indicate individual differences in response to antidepressants. In addition, we illustrate in a simulation study why attempts to personalize antidepressant treatment using RCTs might be misguided.Methods. We first illustrated the variance components of trials by simulating RCTs and crossover trials of antidepressants versus placebo. Second, we analyzed data of a large meta-analysis of antidepressants for depression, including a total of 222 placebo-controlled studies from the dataset that reported outcomes on the 17 or 21 item Hamilton Depression Rating Scale or the Montgomery-Åsberg Depression Rating Scale. We performed inverse variance, random-effects meta-analyses of the variability ratio (VR) between the antidepressant and placebo groups. Outcomes. The meta-analyses of the VR comprised 345 comparisons of 19 different antidepressants with placebo in a total of 61144 adults with an MDD diagnosis. Across all comparisons, we found no evidence for a larger variance in the antidepressant group compared with placebo overall (VR = 1.00, 95% CI: 0.98; 1.01, I2 = 0%) or for any individual antidepressant. Interpretation. Our findings did not provide empirical support for individual differences in response to antidepressants.
‘Fear’ of Crime: Role of Defensive Personality Factors for Concern About Crime
Authors: Satchell Liam , Waddup Oliver James , Bacon Alison , Corr Philip
Published: September 2019

Research into ‘fear of crime’ often interchangeably uses the terms ‘anxiety’, ‘fear’ and ‘worry’. However, neuropsychological and personality research makes a crucial distinction between fear, anxiety and worry. Theoretically, it is likely that anxiety (rumination on the past and worry about the future) rather than fear (i.e., immediate reaction to high intensity threat) is a better predictor of ‘fear’ of crime. We studied the relationship between anxiety, fear and anger (using measures from Reinforcement Sensitivity Theory) and concerns about becoming a victim of crime. We also investigated the relationship between responses to hypothetical threat scenarios and general concerns about crime. In our sample (N = 250), we found, contrary to our predictions, that personality traits related to general fearfulness were predictive of concerns about crime – more so than traits related to anxiety or anger. Responses to hypothetical threat scenarios were predictive of concerns about crime, but less so than trait fear. Overall, our results suggest that it may, after all, be correct to suggest that concerns about becoming a victim of crime are more to do with being afraid than anxious or angry and we discuss the theoretical implications of this effect.

Published: September 2019

Copious facts have demonstrated that UV radiation is harmful to cyanobacteria. Sun-screening compounds such as mycosporine-like amino acids (MAAs) protect these organisms from deleterious UV radiation. MAAs absorb UV radiation in the range of 310 to 362 nm. These natural sunscreens obtained from cyanobacteria are excellent alternative to present day synthetic UV filters. In the present study, several cyanobacteria were collected from six historical Kunds of Varanasi, India. MAAs profile of these cyanobacteria was recorded with the help of UV-Vis spectroscopy, High performance liquid chromatography (HPLC) and Fourier transform infrared (FTIR) analysis. Various MAAs were identified as Porphyra-334 (λmax = 334 nm), Palythine (λmax = 320 nm), Asterina-330 (λmax = 330 nm), Mycosporine-glycine (λmax =310 nm) and Mycosporine-methylamine-serine (λmax =327 nm) having retention times (RT) of 3.62, 1.65, 1.53, 2.55 and 1.51 min, respectively, obtained from different cyanobacteria (Microcystis aeruginosa, Anabaenopsis sp., Merismopedia sp., Aulosira fertilissima, Rivularia sp., Phormidium sp., Nostoc sp. and Stigonema sp.). It is concluded that these MAAs from different historical Kunds may provide protection to the cyanobacteria growing thereof from the adverse effect of harmful UV radiation. MAAs are considered to be potential bioactive compounds that are highly intriguing from biotechnological perspective.

Pollen morphology of twelve species of angiosperms from Central Nepal was cytologically carried out in present investigation. In this investigation pollen morphology of Bignonia venusta Ker Gawl. and Jacranda mimisifolia D.Don from the family Bignoniaceae; Brassica compestris L. from Brassicaceae; Cuphea hyssopifolia Kunth. from Lythraceae; Coriandrum sativum L. from Apiaceae; Crepis japonica L. and Dichrocephala integrifolia (L f.) kunzte. from Asteraceae; Delphinium ajacis L. from Ranunculaceae; Dianthus barbetus L. from Caryophyllaceae; Euphorbia Milii Des Moul. and Euphorbia pulcherima L. from Euphorbiaceae and Magnolia fuscata from Magnoliaceae were studied. Shape of the pollen grains found to be mostly spheroidal, few circular, one elliptical, one triangular and one elongated in this study. Sculpture of exine wall found to be smooth, echidnae, tected, reticulated and perforated type. Aperture of the pollen grains found to be triporate to pentaporate. The large, medium and small sized pollen grains were observed in present research. The high diversty of sculpture type in pollen grains of angiosperms has been associated to diversity in pollination systems. Smooth pollen grains are linked with wind or water pollination while sculptured pollen grains associated with biotic pollination. The morphology of pollen grain is one of the significant tools in solving some taxonomic problems such as identification, tracing phylogenetic relationship on the family, generic or specific level and in plant systematic and evolution.

Published: September 2019

Current society is heavily influenced by science and technology, indicating the need to train generations with critical ability to analyze messages and make responsible decisions in the context in which they act. This is reflected in teaching in general, requiring the university to be a stimulating environment and not merely transmitting knowledge. The teaching-learning process in science education, in particular engineering, can not therefore be restricted to traditional methods. New practices and technologies, with diversified resources and strategies, have been necessary in the improvement of teaching. The present work had the objective of developing an active method for teaching in engineering, at the School of Engineering of Lorena, University of São Paulo. The results show that students crave experiences that develop transversal competences, and that the transmission of theoretical content loses its place for teaching that promotes a process of autonomous construction of knowledge.

Published: September 2019

Rural credit in family farming, as an instrument of leverage for growth in agricultural production, plays a fundamental role in fostering the local economy. Thus, this shields small farmers against market competitiveness. Hence, this study aimed to analyze the perception among rural producers of agricultural credit in family farming as an instrument for strengthening their productive capacity, income distribution in rural areas and the promotion of farmers' quality of life. For this, bibliographic research and a field study were carried out, collecting data through interviews with small farmers who are members of an association of small producers in a Brazilian state in the Amazon region. The results show that rural credit has a strong influence on the local economy and is this important for family farming. A credit line already served all the respondents and 70% stated that between 91% and 100% of the resources used in production were originally bought on credit and unanimously said that rural credit had an impact on increasing income and income production.

Published: September 2019

Regardless of the changes in the economy of the country in recent years caused by the global financial crisis, Brazil has managed to stand positively, despite the many variations in the national and international economic scenario. In the rise of the economy, the automobile sector was a prominent contributor, making it more advantageous for a consumer to purchase a new vehicle. This article aims to study the factors in the city of Cacoal that influenced a consumer’s decision to buy a new car. The methodology was descriptive research, using the deductive method, a qualitative and quantitative approach, and bibliographic research. To collect our data, we used a questionnaire containing 14 questions, some semi-open and some multiple-choice closed, sent in a link via email and Whatsapp, with the help of the Google Forms tool. In our results, it was observed that a consumer’s buying behaviour receives influences from both the external environment and the social group, both of which have a direct impact on the process of deciding to buy a new vehicle. The digital media, in the form of specialized electronic magazine websites, have become popular for consumers to consult. It was found that consumers researching in order to make a purchase decision consider the following decision factors first: quality, trust in technical assistance, confidence in the brand, safety and finally price. To a consumer looking for a new car these items are found to be the most important. The present study aims to set the parameters for future studies and to justify an interest in research.

Sources of matter for Neoarchaean subalkaline magmatic rocks of the Keivy structure (Kola Peninsula)
Authors: Vetrin V. R.
Published: September 2019

The Neoarchaean subalkaline magmatism of Keivy structure is expressed in formation of the volcano-plutonic association of latite-monzonite-granite (ALMG). The quantity of the measured relation 143Nd/144Nd in rocks is determined in 0.511061-0.511365, and values of model age are located in an interval from 3.14 to 3.21 billion years at εNd (2670) from 2.2 to -1.3. The initial relations 176Hf/177Hf in zircon are in limits 0.280950-0.281069, and figurative points of composition form the field around a trend of the CHUR. According to the isotope and geochemical data for all rocks the basic composition of protholits is supposed. In quantity εHf(T) points of zircon are localized in the field of the development of the crust with 176Lu/177Hf = 0.015 and 3.0-3.3 billion years age. It probably demonstrates the formation of initial melts mainly at the expense of matrix with a long time of stay in crust. The formation of ALMG magmas is assumed to appear due to the melting of metasomatically altered rocks of the lower crust during intrusion of basaltic melts initial for the rocks of the dike complex and the gabbro-labradorite massifs into the upper crust.
Influence of surface effects on the bending and buckling of nanowires
Authors: Ilgamov M. A.
Published: September 2019

The static bending and longitudinal stability of nanowires under liquid or gas pressure are considered. Two surface effects are taken into account. The first is due to the difference in elastic properties in the thin surface layer and in the bulk of the material. Effective tensile and flexural stiffness can be more or less than conventional stiffness, depending on the material. The second effect is due to the interaction of excess pressure on the circular side surface of the wire and the difference of the areas of the convex and concave sides of the surface that appears during bending. This effect is manifested the stronger, the greater the ratio of pressure to the modulus of elasticity of the material and the length of the wire to its diameter. These effects are determined by dimensionless parameters. It has been established that a loss of wire stability may occur under the influence of the second effect. A possible method for determining the dimensionless parameter, which determines the differences of elastic properties in a thin layer near the surface and the base material, is proposed.
The first results of U-Pb datings of detrital zircons from the basal deposits of the Upper Precambrian of the Subpolar Urals
Authors: Pystin А. M. , Pystina Yu. I. , Hubanov V. B.
Published: September 2019

In the north of the Timan-Ural region, in contrast to its southern regions, there are no Lower Riphean deposits. The question of the presence of Middle Riphean stratons here remains open, since their age is accepted conditionally. In the Subpolar Urals, the Puiva Formation, which lies at the base of the Upper Precambrian section of this region, belongs to the Middle Riphean. The first U-Pb results of the LA-SF-ICP-MS dating of detrital zircons from terrigenous deposits of the Puiva Formation give reason to limit the lower age interval of their formation abroad about 900 million years ago. The obtained dating of the detrital zircons of their obviously basal terrigenous sediments for the Timan-Northern Ural Upper Precambrian, taking into account already available data on the age of the Upper Precambrian strata of this region, indicate that the lower age limit of the Timan continental margin of the Baltic is close to the boundary of the Middle and Late Riphean.

ABSTRACTTujuan dari penelitian ini adalah Mengetahuin nilai Earning Per Share (EPS), Dividend Per Share (DPS) dan Harga Saham pada PT Wijaya Karya (Persero) Tbk guna mengetahui pengaruh Earning Per Share (EPS) dan Dividend Per Share (DPS) baik secara parsial maupun simultan terhadap harga saham WIKA pada periode 2010-2014.Metode penelitian mengunakan pendekatan deskriptif asosiatif serta analisis data menggunakan analisis regresi linier berganda dan pengujian asumsi klasik yang meliputi : Uji Normalitas, koefisien korelasi linier berganda dan parsial serta koefisien determinasi (Adj R.Square). Berdasarkan hasil analisis data, variabel EPS tertinggi PT. WIKA terjadi pada tahun 2014 yaitu sebesar 119.71 dan tahun terendah terjadi pada tahun 2010 yaitu sebesar 51.86. DPS pada tahun 2010-2013 mengalami peningkatan, dimulai pada tahun 2010 sebesar 15.55, tahun 2011 sebesar 23.33, tahun 2012 sebesar 25.88, dan pada tahun 2013 sebesar 30.50. Tetapi pada tahun 2014 mengalami penurunan sebesar 23.94. DPS menunjukan trend fluktuatif. Uji signifikansi (Uji T) pada variabel EPS diperoleh  (21,435) >  (4,303) sehingga jatuh pada daerah penolakan  ( ditolak,  diterima) dapat dilihat pula besar angka signifikansi yaitu 0,002 yang berarti angka ini lebih kecil dari tingkat signifikansi (0,002 < 0,05), maka dapat ditarik kesimpulan bahwa perubahan EPS secara parsial berpengaruh signifikansi terhadap perubahan harga saham. Dengan melakukan perbandingan pada variabel DPS yaitu  (-9,842) <  (4,303) sehingga dapat dilihat pula besar angka signifikansi sebesar 0,010 yang berarti angka ini lebih besar dari tingkat signifikansi (0,010 > 0,05), maka dapat ditarik kesimpulan bahwa perubahan DPS secara parsial tidak berpengaruh signifikan terhadap perubahan harga saham. Hasil uji signikansi (Uji F) dengan kondisi ini dimana  lebih besar dari pada  (251,851 > 9,55) dan nilai signifikansi lebih kecil dari α = 0,005 (0,004 < 0,05), maka dapat diambil kesimpulan adalah  ditolak dan  diterima yang berarti variabel EPS dan DPS berpengaruh signifikan secara simultan terhadap harga saham. Koefisien Determinasi R2 kondisi ini menunjukkan, seberapa besarnya pendapatan diterima oleh pemegang saham. jadi dapat disimpulkan bahwa EPS dan DPS berpengaruh sebesar 99,2% terhadap Harga Saham, sedangkan 1,8% dipengaruhi oleh variabel lain yang tidak diketahui di dalam penelitian iniKeyword : Earning Per Share (EPS), Dividen Per Share (DPS), Harga Saham.

Introdução: A quimioterapia aparece como promotora do aumento no peso e no percentual de gordura, os quais estão em conexão com o desenvolvimento da carcinogênese mamária. Objetivo: Avaliar a influência do tratamento antineoplásico sobre a composição corporal e vetores de impedância bioelétrica em mulheres com neoplasia da mama. Método: Estudo observacional, tipo antes e depois, realizado de março de 2012 a junho de 2013, no Hospital Geral de Fortaleza (Ceará, Brasil), com 30 mulheres com tumor na mama, avaliadas após o diagnóstico e antes do tratamento antineoplásico (M1), e após o tratamento antineoplásico (M2). Coletaram-se dados antropométricos, de composição corporal e valores de resistência (R) e reactância (Xc) para análise vetorial de impedância bioelétrica (BIVA). Resultados: Os percentuais de gordura corporal estiveram acima do recomendado nos dois momentos [M1= 35,6% (4,9) e M2= 35,3% (4,7)] e os valores de massa magra foram, respectivamente, 64,3% (4,9), 64,6% (4,7) sem diferenças significativas. A Reactância (p=0,001) e o ângulo de fase (p=0,000) apresentaram-se diminuídos no M2. Os vetores de impedância, quando comparados M1 e M2, não mostraram deslocamento significativo (p=0,053). Entretanto, ao serem comparados com o vetor médio de uma população de referência, apresentaram deslocamento significativo antes (T2=95,2; p=0,000) e após (T2=53,2; p=0,000) o tratamento antineoplásico, indicando alterações nas propriedades elétricas dos tecidos, retenção hídrica e perda de massa celular. Conclusão: A composição corporal não se alterou após o tratamento antineoplásico. As modificações nos vetores de impedância foram sugestivas de alterações nas propriedades elétricas dos tecidos, indicando pior prognóstico clínico.

Published: September 2019

This study shifts the tendency to focus on international students’ negative experiences of undertaking education in a host country to a group that enjoys an elevated level of support. By looking at international student-athletes compared with non-athletes, it is shown how the former group experiences the benefits of social capital. Insights relating to international student-athletes in the US reveal strong and ongoing support from coaches and teammates. It is shown that international student-athletes have far greater support structures compared with international non-athletes. In doing so, this study presents a new perspective to debates on what higher education institutions in host countries can do to support their international student populations.

This
study examines to understand the smartphone users' attitudes and intention
towards social media apps with the perspective of three widely used models;
uses and gratification (U&G) theory's psychological motivations factors
(entertainment, sociality, and information), innovation diffusion theory (IDT)
and the technology acceptance model (TAM). Thus, in the framework of this
research, the proposed research model consists of three respective models. The
random sampling technique used to collect research samples from Usak province
in Turkey.  The data used in testing the
research model collected by the questionnaires. The numbers of the valid survey
collected were 527. The structural equation modeling conducted to analyze the
research assumptions and model. The outcomes indicate that the users' perceived
ease of use (PEOU) influenced by complexity, relative advantage, observability,
trialability. Perceived usefulness (PU) affected by compatibility, relative
advantage, observability, trialability, and PEOU, while with attitude together
influencing intention to use social media app. Another outcome showed that
attitude determined by sociality, entertainment, PEOU, and PU. Empirical
results also provided support for the integrative approach. The results show
that TAM in the extension of an innovation diffusion theory and psychological
motivations can help decision-makers in the social media app.

Contact dermatitis is an acute or chronic inflammatory reaction in the form of erythema, papular edema, vesicles, squares and itching caused by irritants or substances that attach on the skin. The purpose of this study is to determine the strong relationship between personal hygiene and the use of PPE in tobacco farmers with the incidence of contact dermatitis in tobacco farmers in the Ambulu village of Jember. This observational research had done by using a cross-sectional approach. This study utilizes a total population of 61 tobacco farmers.  The dependent variable in this study is the incidence of contact dermatitis which is experienced by tobacco farmers in the Ambulu village. While the independent variables are personal hygiene and the use of personal protective equipment (PPE). To discover the strong relationship between dependent and independent variables, there will be tested by statistical tests which applies the spss application and Chi-Square test. Resulting from the research, the relationship between personal hygiene and the incidence of contact dermatitis are categorized as a strong relationship with the point is 0.627. Whereas the use of PPE and the incidence of contact dermatitis obtains a result of 0.276 which is categorized as moderate relationships. As suggestions for tobacco farmers in Ambulu village is to pay attention to their personal hygiene and use Personal Protective Equipment while working.

Background: Platelet Rich Plasma (PRP) is increasingly applied in clinical practice to treat knee degenerative pathology. Both PRP and hyaluronic acid (HA) have been extensively used to improve lubrication, modulate inflammation and modify the catabolic micro-environment of the joint.

Objective: This study was aimed to evaluate the potential synergistic effects of PRP in combination with hyaluronic acid in primary knee osteoarthritis.

Methodology: This randomized control trial was carried out on adult patients with primary knee osteoarthritis who attended the Pain Clinic of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh, during the period of September 2015 to August 2017. The patients were randomly assigned to one of the two groups designated as group P (control group) who were only treated with PRP and group PH (experimental group) who were treated with the combination of PRP and hyaluronic acid. After providing the allocated treatment, all patients were undergone follow-up examination at 1st week, 1st month and 3rd month for pain improvement by VAS scale and for functional improvement by International Knee Documentation Committee (IKDC) score.

Results: A total number of 34 patients were recruited for this study. Visual analogue score 1st month (5.85±0.83) and 3rd month (3.01±0.12) follow up showed statistically significant difference among two group (p=0.001). Inter group comparison showed that, mean VAS score of group PH (3.01±0.12) decreased more than Group P (4.01±1.01). In case of functional improvement, group PH also showed statistically better improvement during 1st month (45.76±3.25) and 3rd month (62.06±5.37) follow up than Group P.

Conclusion: In conclusion articular platelet rich plasma in combination with hyaluronic acid provide better pain relief and improvement of functional status than PRP therapy alone in primary knee osteoarthritis.

Background: BPH is one of the most common cause of LUTS which significantly impairs the quality of life. TURP is minimally invasive surgical procedure for Benign Prostatic hyperplasia which has impact on quality of life. Impact on quality of life can be measured by QoL score and effect of TURP can be evaluated.

Objective: The purpose of the present study was to evaluate the impact of transurethral resection of prostate (TURP) on Quality of Life (QoL) score.

Methodology: This prospective study was carried out in the Department of Urology, Shaheed Suhrawardy Medical College and Hospital, Dhaka, from July 2015 to June 2016. Total fifty patients between 50 to 72 years attending for the treatment of benign prostatic hypertrophy (BPH) with lower urinary tract symptoms (LUTS) were included for the study according to inclusion & exclusion criteria. All of them were evaluated with baseline international prostate symptoms score (IPSS), QoL score, peak urinary flow rate (Qmax), voided volume, voiding time and PVR and were recorded in a predesigned data sheet. Selected patients underwent Transurethral Resection of Prostate. They were followed after 1 month and 3 months with same parameter and compared with the baseline values.

Results: The baseline international prostate symptoms score (IPSS) in this study was 25.18±1.45. At one month and three months follow up visits after TURP, the IPSS was decreased to 15.0±1.07 and 8.14±0.76 respectively. There was significant improvement of peak urinary flow rate (Qmax) in the postoperative period, at the 1st follow up visit after one month of TURP (15.78±1.42, p<0.001) and at the 2nd follow visit after three months of TURP (18.78, p <0.001). The mean QoL score was 5.30±0.46 before TURP. After one month of TURP it was 3.20±0.45 and after 3 months of TURP it was 1.86±0.57.

Conclusion: There is a significant improvement of quality of after TURP.
