How memories of study abroad experience are contextualized in the language classroom
Authors: Lee Sheng-Hsun
Published: October 2019

Many study abroad researchers recruit genres, such as diary, interview, and questionnaire, to study memories of study abroad experience and their relationship with language learning. Whether quantitative or qualitative, much emphasis is on individual representations and circulation of past experience, not the here-and-now, nor the impact a person’s study abroad memories has on their subsequent life practices. In this study, I draw on sociocultural theory to analyze study abroad experiences recounted in various types of language classroom activity. I show that memory is constantly (re)shaped by intermental, interactional, and institutional forces, as when students are mediated at lexical, grammatical, and discursive levels to reconstruct their experienced past vis-à-vis goal-directed activity in class. I highlight discursive practices rememberers adopt to render their version of the past credible and authentic, and explain how such practices create opportunities for mediation in the classroom. The findings demonstrate that contextualized remembering is a mediated process of objectifying personal experience, and that memory discourse is a mediating tool for transforming mental and social activity. Thus, remembering is not simply the retrieval or circulation of individual subjectivities, but also an active social practice.
Migrant women, work, and investment in language learning: Two success stories
Authors: Iikkanen Päivi
Published: October 2019

In the media, migrant mothers are often portrayed as uneducated, having trouble learning a new language, and preferring to stay at home rather than entering paid employment. This article offers a contrasting point of view as a result of examining how two migrant women narrativize their experiences of language learning and working-life-related integration during a three-year period. Specific attention is paid to how the women make sense of their language use over time, and how this may have contributed to their integration into working life and the wellbeing of their families. Interview data was analyzed using the short story analytical approach, focusing on both the content and the various scales of context portrayed in the stories. The analysis is informed theoretically by the concept of investment. The findings indicate that, first, English was used when interacting with members and institutions of the Finnish society, but gradually the use of English was replaced by an emerging Finnish proficiency. At first with the help of English and later, by deciding to invest in learning Finnish, both key participants managed to build new careers and meaningful lives for themselves and their families in a new environment.

Published: October 2019

Background

Although accumulating evidence suggests that the hemostatic balance is impaired in patients with hypertriglyceridemia, hyperbilirubinemia or hemolytic anemias, little is known on the underlying biological mechanisms. This experimental study was aimed at exploring whether increasing values of triglycerides, bilirubin or cell-free hemoglobin promote thrombin generation in plasma.

Methods

Three different pools were prepared from three different sets of 20 normal routine plasma citrate samples. The native pools were spiked with increasing amounts of exogenous triglycerides (up to 8.8 mmol/L), bilirubin (up to 350 μmol/L) or autologous hemolyzed blood (up to 3.5 g/L cell-free hemoglobin). Using the fully-automated thrombin generation analyzer ST Genesia, we measured the following parameters: lag time (LT), time to peak (TP), peak height (PH) and endogenous thrombin potential (ETP).

Results

A sustained increase of PH and ETP was found in parallel with increasing triglyceride concentrations, peaking in the aliquot with 8.8 mmol/L. Conversely, LT and TP displayed an opposite trend, reaching a maximum decrease in the 8.8 mmol/L aliquot. Increasing bilirubin concentrations promoted remarkable increases of PH and ETP and decreases of TP and LT, up to 211 μmol/L. After this threshold, all parameters tended to return towards baseline values. A constant increase of PH and ETP was also noted in hemolyzed samples, peaking in the 3.5 g/L cell-free hemoglobin aliquot, whereas the TP and LT remained unchanged in all hemolyzed aliquots.

Conclusions

Our findings suggest that hypertriglyceridemia, hyperbilirubinemia and hemolysis may promote a hypercoagulable state in human plasma.

Authors: Yin Jiangning , Jiang Jun , Wang Huajun , Lu Guoyuan
Published: October 2019

Background

We aim to investigate the protective effects and potential mechanisms in specneuzhenide (SPE) on renal injury in rats with diabetic nephropathy (DN).

Results

SPE could inhibit the decrease of body weight compared with the model group (P<0.05), and trigger improvement in the renal index (P<0.05). High dose and low dose SPE could trigger a significant decrease in serum IL1β, IL-6 and TNF-α compared with the model group (P<0.05). SPE could attenuate the glomerular lesions in DN rats. SPE induced up-regulation of podocin and CD2AP (P<0.05).

Conclusion

SPE showed protective effects on renal injury through attenuating the pathological injury and urine protein. This process may be closely related to the modulation of CD2AP and podocin expression.

Published: October 2019

Consumers’ preference for food is ever-changing from carbohydrate to protein since protein plays a vital role in the balanced and healthy growth of human being. Among different sources of protein, animal sourced protein foods are getting popularity over time in United States. How demand for animal sourced protein food items are changing, and to be specific which animal food items are preferred by consumers are necessary to know both for producers and suppliers. This study estimates consumer demand for animal sourced food items in U.S. employing linear approximation of AIDS (LA-AIDS) model. Monthly per capita consumption expenditure data on aggregate and disaggregate animal protein items and price indices at national level from 1995 to 2016 have been collected from the Bureau of Economic Analysis of United States. The data consists of monthly per capita consumption expenditure on beef and veal, pork, other meats, poultry, and fish and seafood, and their price indices. The result shows exogenous growth in the budget share of all meat items. Estimated expenditure and cross price elasticities suggest that all goods are normal in nature and substitute to each other. In addition, weak separability test suggests that meat items are separable from non-meat items. The findings of the study would be helpful understanding consumer preferences and behavior for allocating budget among different sources of animal protein.
Cult and Crisis: A GIS Approach to the Sacred Landscape of Hellenistic Attica
Authors: Graml Constanze , Hunziker Manuel , Vukadin Katharina
Published: October 2019

From a political point of view, 3rdcentury BCE Athens represents a shattered unity. Parts of the Athenian countryside and even the city itself were occupied by foreign troops. This loss of control affected the city’s political, economic, social, cultural, and religious life. Since Cleisthenic times, relations between political units and religious communities had become institutionalised through specific cults. Other cult places of relevance to the larger community and therefore with a catchment area that exceeded a deme, e.g. Eleusis, were also affected, as they lay within the occupied territories. This partial inaccessibility of the countryside risked the disruption of religious duties. The project “Cult and Crisis: The Sacred Landscape of Attica and its Correlation to Political Topography” aims to identify potentially affected cult places with no limitations regarding their possible catchment area by analysing their placement in relation to foreign military bases. Alterations in cult practice can plausibly be detected in changes ranging from cessation to the rerouting of ritual movement or the establishment of substitute cult places. As these “solutions” rarely feature in written sources, our GIS-based approach will focus on material remains from sanctuaries. Although an object’s use for ritual practice cannot be deduced with certainty, the distribution of finds certainly attests to human activity. This contribution presents a trial of this approach, taking the Sounion area as its case study.

Authors: Siddiq Muhammad , Bakhat Khush , Ajmal Muhammad
Published: October 2019

In this work, poly (vinylcaprolactam-co-itaconic acid) microgel was prepared by free radical polymerization. Silver nanoparticles were prepared in synthesized microgel networks by in situ reduction of Ag+ ions, loaded in microgel from aqueous solution of AgNO3. The prepared microgel was characterized by Fourier transformation infra-red spectroscopy, UV-Visible spectroscopy, fluorescence spectroscopy, X-ray diffraction, laser light scattering, thermal gravimetric analysis, differential scanning calorimetry and transmission electron microscopy. Swelling behavior of microgel was studied as a function of temperature and pH. The microgel was found to be in swollen state at low temperature and basic medium while in collapsed state at high temperature and acidic medium. A slight decrease in swelling capacity of microgel was observed after the fabrication of silver nanoparticles. A decrease in the emission intensity and a red shift in surface plasmon resonance wavelength of silver nanoparticles was observed with pH induced swelling of microgel. Catalytic activity of the composite microgel was studied by using them as catalyst for the reduction of 4-nitrophenol, methyl orange and methylene blue. Effects of temperature and catalyst dose were also investigated. The reduction rates of 4-NP, MB and MO were found to be 0.859, 0.0528 and 0.167 min−1, respectively. The change in catalytic performance and shift in absorption maxima and emission intensity of composite microgel as a function of temperature and pH reveals that this system has potential to be used as tunable catalyst and optical sensor.
Heuristic based real-time hybrid rendering with the use of rasterization and ray tracing method
Authors: Walewski Patryk , Gałaj Tomasz , Szajerman Dominik
Published: October 2019

Nowadays, rasterization is the most common method used to achieve real-time semi-photorealistic effects in games or interactive applications. Some of those effects are not easily achievable, thus require more complicated methods and are difficult to obtain. The appearance of the presented worlds depends to a large extent on the approximation to the physical basis of light behaviour in them. The best effects in this regard are global illumination algorithms. Each of them including ray tracing give the most plausible effects, but at cost of higher computational complexity. Today’s hardware allows usage of ray tracing methods in-real time on Graphics Processing Units (GPU) thanks to its parallel nature. However, using ray tracing as a single rendering method may still result in poor performance, especially when used to create many image effects in complex environments. In this paper we present a hybrid approach for real-time rendering using both rasterization and ray tracing using heuristic, which determines whether to render secondary effects such as shadows, reflections and refractions for individual objects considering their relevancy and cost of rendering those effects for these objects in particular case.
Research and Analysis of the Effect of Heat Treatment on Damping Properties of Ductile Iron

Published: October 2019

With the continuous development of metal manufacturing technology, high-strength and high-hardness ductile iron materials have excellent comprehensive performance. Many performance indexes are comparable to those of alloy steels, and they have excellent casting properties. Many large-scale parts produced by cast steel are slowly being replaced by this material. Ductile iron is obtained by a spheroidizing treatment and inoculation to obtain spheroidal graphite. The mechanical properties of cast iron have been effectively improved, especially plasticity and toughness, and the strength obtained is higher than that of carbon steel. Ductile iron has the properties of iron and the properties of steel. It is a new type of engineering material with high plasticity, strength, corrosion resistance, and wear-resistance. Because of its excellent performance, it has been successfully used to cast parts with high-stress conditions, high strength, toughness and wear resistance. Due to the small splitting effect of ductile iron on the metal matrix, the stress concentration is effectively eliminated. Therefore, the matrix structure of ductile cast iron is changed by heat treatment, thereby improving its mechanical properties and the damping performance of the material itself. Through a heat treatment process experiment of ductile iron, the related process and technical measures of damping performance in the heat treatment production process are obtained.

Published: October 2019

Copper is an essential trace element and is an integral part of many metabolic and other chemical processes in cells and tissues. Copper-based nanoparticles (CuNPs) have wide industrial and engineering applications, as catalysts, sensing materials, part of superconductors, storage systems, and phototermal / thermoelectric materials. In recent years, their potential use in biology and medicine has also contributed to the increased interest by scientific community. Unfortunately, many aspects of CuNP interactions with cells and tissues remain unknown. It is unclear if, in a living organism, CuNPs behave the same way as conventional metallic copper. Possible impact of CuNPs on the functioning of organs such as liver, kidney and brain is of particular concern. This concise review aims to cover recent research on potential CuNP toxicity, with the emphasis on neurotoxocity, nephrotoxicity and hepatotoxicity. Also, potential implications of CuNPs toxicity in fundamental and clinical medicine are discussed.

Authors: Safaie Naser , Entezari Maleki Taher , Alhasan Zainab , Hosseini Nafiseh
Published: October 2019

Background: Clopidogrel is an antiplatelet drug that is widely prescribed for cardiovascular disease. In cardiac surgery, it is used in patients after coronary artery bypass grafting (CABG) to prevent coagulation disorders. The irrational use of this drug can lead to bleeding and require surgical exploration along with increased therapeutic cost. Therefore, it is essential to study the pattern of clopidogrel use in hospitals. Methods: This study was conducted for a 6-month period to evaluate clopidogrel adherence to American Heart Association/American College of Cardiology (AHA / ACC) Guidelines in patients after coronary artery bypass grafting (CABG) surgery. Patients’ data were recorded in the pre-designed questionnaire, which included demographic data, past medical history, drug history along with the indications of clopidogrel use. Data analysis was performed by SPSS 16 software. Results: A total of 120 patients with a mean age of 61.3 ± 8.9 years old were recruited in to this study. Male to female ratio was 3 times. The main risk factors in patients with ischemic heart disease were male gender (74.2%), hypertension (80%), and smoking (47.5%). In addition to clopidogrel, most of the patients received aspirin (95.8%), followed by heparin (31.7%), and warfarin (5%) or enoxaparin (2.5%). The clopidogrel indications were non ST-elevation myocardial infarction / unstable angina (33.3%), acute ST-elevation myocardial infarction (20.8%), recent myocardial infarction or stroke (3.3%), and CABG off-pump (30%). In 70.8% of cases, the administration of clopidogrel was consistent with AHA / ACC standard guidelines and most of the irrational cases belonged to the usage of the drug after on-pump CABG surgery. Conclusion: The results showed that the rates of adherence to clopidogrel use with the AHA/ACC guidelines for patients who underwent CABG surgery was relatively good, but required further improvement.

Authors: Devaka Naga Venkata Suresh Kumar , Rao Vallabhaneni Madhusudhan
Published: October 2019

Background: A new stability indicating RP-HPLC based assay method was developed to quantify ivermectin and praziquantel simultaneously and applied effectively to tablets. Methods: The simultaneous assay of ivermectin and praziquantel by RP-HPLC was done using an YMC C18 (250 mm × 4.6 mm, 5 µm) column with a mobile phase mixture of 0.1M disodium hydrogen phosphate (pH 4.5) and acetonitrile (55:45, v/v) using a isocratic flow rate of 1.0 ml/min and measured at 242 nm using photodiode array detector. All parameters were validated following the ICH guiding principles. The method was applied to quantify ivermectin and praziquantel simultaneously in tablets. Results: The retention values of ivermectin and praziquantel were 3.465 min and 4.468 min, respectively. The method’s linearity was found to be 1-3 µg/ml (ivermectin) and 25-75 µg/ml (praziquantel). The limit of detection was 0.010 µg/ml (ivermectin) and 0.046 µg/ml (praziquantel); limit of quantification was 0.033 µg/ml (ivermectin) and 0.155 µg/ml (praziquantel). The percent relative standard deviation of ivermectin and praziquantel was ˂1.0%. The percent assay was 99.51% and 99.20% for ivermectin and praziquantel, respectively. In tablets, the percent recovery of ivermectin and praziquantel was 99.60% and 99.38% with a percent relative standard deviation value of 0.353% and 0.106%, respectively. Stability indicating capability of the method was demonstrated through the stress degradation studies. Conclusion: The developed method was proved to be selective, precise and accurate for the quality control of ivermectin and praziquantel in tablets.
What if Cocrystallization Fails for Neutral Molecules? Screening Offered Eutectics as Alternate Pharmaceutical Materials: Leflunomide-a Case Study
Authors: Bala Madhu , Gautam Manoj Kumar , Chadha Renu
Published: October 2019

Background: The manuscript is aimed to optimize the biopharmaceutical parameters of a poorly soluble, neutral anti-rheumatic drug ‘leflunomide’ by preparing its non-covalent derivatives (NCDs). For this various monocarboxylic acids- (adipic acid, picolinic acid) and dicarboxylic acids (maleic acid, malonic acid, sorbic acid), as well as pyridine carboxamide derivatives (nicotinamide, isonicotinamide), are used as coformers. Methods: The novel solid forms were rationally prepared and systematically characterized. Further, these solid forms were subjected to equilibrium solubility and intrinsic dissolution rate (IDR) analysis in three aqueous media (pH 1.2, pH 4.5 and pH 6.8). In vivo plasma studies in male Wistar rats were done to assess the effect on area under the curve (AUC) and the maximum concentration (Cmax) of leflunomide in prepared solid forms. Results: These NCD were primarily characterized to be eutectics rather than cocrystals as expected. The stoichiometry was established by phase diagrams. The negative value of heat of mixing indicated them to be of cluster type. In addition, leflunomide in eutectics showed approximately 9 folds increase in solubility up to 4 hours. Besides this, approximately 4 folds enhancement in the in IDR was also observed. Maximum increase in bioavailability indicated by enhanced values of AUC and Cmax (490.29 μg h-1 mL-1 and 31.42 μg mL-1, respectively) for leflunomide-maleic acid eutectic in comparison to pure LEF (AUC: 193.20 μg h-1 mL-1 and Cmax: 12.09 μg mL-1). Conclusion: The unsuccessful cocrystallization experiments were found be the latent eutectics. The evaluation of these novel eutectics of poorly soluble drug exhibited possibility to further amplify the scope of accessible material phase options other than pure active pharmaceutical ingredient (API) without disturbing the structural integrity.
Identifying Plume Mode via WSR-88D Observations of Wildland Fire Convective Plumes and Proposed Tactical Decision Support Applications

Published: October 2019

To date, the use of Doppler radar (WSR-88D) in wildland fire operations has been limited, with tactical applications focused on analyzing ambient atmospheric features. This paper presents geographically diverse analysis of radar-observed wildland fire convective plumes to determine indicators of plume mode for tactical
decision support. Through the visualization of buoyancy via thermal bubbles and vertical plumes, plume mode is revealed via WSR-88D interrogation of three Southern Great Plains grass/shrub fires and two timber fires in
Texas and California. Analogous to thunderstorm convective modes, past research has identified two distinct plume modes of wildland fire: multicell and intense convective plume. Multicell plume mode is characterized by a series of shallow discrete cells that move away from the fire’s main buoyancy source, with successive cells
rising, expanding, and replacing cells from the updraft source. This process, known as the thermal bubble concept, occurs most notably in strong vertical wind profile environments with a strong advection component.
These cells or thermal bubbles are observed via WSR-88D data for three Southern Great Plains cases. Intense convective plumes are observed to be vertical with the low-level reflectivity maximum and maximum echo top juxtaposed and occurrence is confined to weak wind environments; these plume structures are identified in the two timber fire cases. An important WSR-88D signature, the back-sheared convective plume (hereafter BSCP), is identified in terms of transverse vortices and vortex rings, which may imply enhanced combustion rates due to increased turbulent mixing. Determination of plume convective mode via radar offers meteorologists the ability to detect changes in plume mode and to provide important tactical decision support information about
fire behavior.

Published: October 2019

Environmental phenols and phthalates are common ingredients in personal care products and some have been implicated in breast cancer progression. We have previously identified genes differentially expressed in response to low-dose exposure to diethyl phthalate (DEP) and methyl paraben (MPB) in a rat model. Herein we explore if these genes are associated with breast cancer mortality in humans. We profiled MPB- and DEP-responsive genes in tumors by NanoString® from a population-based cohort of 606 women with first primary breast cancer among whom 119 breast cancer-specific deaths occurred within 15+ years of follow-up. For each gene, Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Results were validated in two publicly available datasets. The following results were obtained. From 107 DEP- and 77 MPB-responsive genes profiled, 44 and 30 genes, respectively, were significantly associated with breast cancer-specific mortality. Some top DEP-responsive genes are novel for breast cancer mortality, such as ABHD14B (for high-vs-low expression, HR 0.36, 95% CI: 0.2–0.5) and TMC4 (HR 0.37, 95% CI: 0.3–0.5); top hits for MPB (SLC40A1 (HR 0.37, 95% CI: 0.3–0.5) and NTN4 (HR 0.39, 95% CI: 0.3–0.6)) are well-known predictors of breast cancer survival. PLEKHA6 was another novel survival predictor, sensitive to hormonal receptor status (HR 0.5, 95% CI 0.3–0.9 for hormonal receptor-positive and HR 3.2, 95% CI 1.7–6.2 for -negative group). In conclusion, tumor expression of DEP- and MPB-responsive genes is associated with breast cancer mortality, supporting that exposure to these chemicals may influence the progression of breast cancer.

Published: October 2019

Forage legumes such as Leucaena leucocephala, besides being a rich source of protein for animal feed, its inclusion in silvopastoral systems provides fundamental components to improve soil properties. These plants have the ability to establish symbiotic association with the genus Rhizobium sp. and fix biologically atmospheric nitrogen favoring growth and development, being reflected in production increases. The objective of this research was to evaluate the capacity of native isolates of Rhizobium sp. and a commercial strain in biological nitrogen fixation (BNF) in L. leucocephala plants. Two separate bioassays to evaluate the efficiency of the FBN of the native isolates and the commercial strain under greenhouse conditions, followed by a randomized complete block design with 7 x 2 factorial arrangement, seven treatments, two factors: native isolates and commercial strains and bacterial concentrations (106 and 108 cells.ml-1), with three repetitions and five experimental units. The first bioassay was carried out with seeds, determining the percentage of germination, the length and thickness of the stem, number of leaves, dry weight of the aerial part, number of nodule/plant and the percentage of nitrogen accumulated in the area part of the plant. In the second bioassay with 30-day-old seedlings, the same variables of the first bioassay were determined, with the exception of the percentage of germination. In the first bioassay, a greater stimulation was found in the germination of L. leucocephala seeds at a concentration of 108 cells.mL-1. Regarding stem length and thickness, accumulated dry matter, leaf  development and nitrogen accumulation, better results were found in the treatments with the native isolates L27, L36 and L38 in a concentration of 106 cells.mL-1 above the commercial strain in concentration of 108 cells.mL-1. The native isolates of Rhizobium sp. exert a positive effect on the FBN and the germination of plants of L. leucocephala, which will allow to conduct future field studies that allow to potentiate the culture of L. leucocephala and silvopastoral systems for bovine feeding.

Objective: to investigate the association between hypertension and anthropometric indicators of central obesity, obtained from two anatomical sites in older adults.Methodology: cross-sectional study that involved 145 older adults, from whom socioeconomic and demographic data and anthropometric indicators of central obesity (waist circumference [CC] and abdominal circumference [CA]) were obtained, which were considered independent variables. A logistic regression model was used to analyze associations and for the discriminatory power of the cut-off points of the hypertension anthropometric indicators, receiver operating characteristic (ROC) curve was performed. Comparisons were made between ROC curves, with the aim of identifying significant differences in the discriminatory power of the anthropometric indicators studied.Results: out of the 145 individuals, 79 were females (54%) and 66 males (46%). Results showed a high prevalence of arterial hypertension in men (69,7%) and women (73,4%). Both CC and CA were significantly associated with hypertension in both genders. Parameters of the ROC curve revealed that both anthropometric indicators of central obesity exhibit good discriminatory power for hypertension in the studied population. The cut-off point for CC was > 83,2 cm for men and > 82,6 cm for women; while for CA it was > 85,1 cm and > 85,4 cm for men and women, respectively.Conclusion: CA and CC are significantly associated with hypertension in both genders, and there is no superiority between them to predict hypertension in the elderly population.

Objetivo: analisar os itinerários terapêuticos de mulheres com câncer do colo do útero (CCU) a partir do tratamento, na região Sudoeste da Bahia, Brasil.Materiais e métodos: estudo qualitativo descritivo e exploratório realizado em uma unidade de alta complexidade em oncologia que é referência para a região sudoeste da Bahia. Cinco mulheres em tratamento para o CCU foram entrevistadas, sendo a coleta de dados realizada a partir de entrevistas semiestruturadas e registros em diário de campo, no período de julho a agosto de 2017. Adotou-se a análise categorial temática.Resultados: emergiram duas categorias empíricas: aspectos simbólicos e experiências de mulheres em tratamento para o CCU e a busca por tratamentos para o CCU. As racionalidades e práticas acionadas no curso dos itinerários revelaram a externalização de signos e significados da doença a partir de elementos biomédicos e sobrenaturais, experiências de adoecimento caracterizadas por sentimentos de dor e sofrimento, superação e enfrentamento como também o acionamento de estratégias terapêuticas de caráter empírico, popular e biomédico.Conclusão: os itinerários tecidos a partir de conexões com familiares, profissionais de saúde, membros da comunidade e a com a religiosidade, denotam que não existem padrões únicos e definidos nas trajetórias em busca de cuidado e que os mesmos podem permitir uma maior aproximação dos sentidos, modos de lidar com a doença e estratégias terapêuticas valorizadas e acionadas por estas mulheres.

Objetivo: compreender as vivências de jovens quanto ao uso da terapia antirretroviral para o HIV.Método: trata-se de uma investigação fenomenológica, fundamentada no referencial teórico-filosófico-metodológico de Martin Heidegger. Foram desenvolvidas entrevistas com dez jovens (16 a 23 anos), em serviço de referência na Região Sul do Brasil.Resultados: as unidades de significados foram: 1. Medo de contar o diagnóstico e de morrer, justificado nas experiências familiares ou sociais; 2. Tomar os remédios é complicado, mas tem que tomar para ficar bem e cuidar do outro e para isso, buscam estratégias; e, de modo contraditório, 3. Tomar os medicamentos é algo normal, tornando a vida diferente. A hermenêutica desvela o modo de ser-com, nas relações que estabelecem com as pessoas que confiam. Apresentaram temor devido à possibilidade do preconceito e da morte. No modo da ambiguidade, expressam que tomar os medicamentos é complicado e também normal, tornando a vida diferente. E, no falatório em que todas as informações parecem ter sido compreendidas, quando na verdade não foram, então os jovens repetem aquilo que escutam dos profissionais e continuam curiosos.Conclusões: concluímos que é necessário um cuidado que fortaleça as estratégias e a rede de apoio para manter o tratamento.

Published: October 2019

Background

In addition to proinflammatory properties, eosinophils can stimulate platelet activation and enhance prothrombotic pathways. In this study, we aimed to investigate the association between the eosinophil percentage (EOS%) and major adverse cardiac events (MACE) in patients with ST-segment elevation myocardial infarction (STEMI).

Methods

This study enrolled a total of 1,909 patients who were diagnosed with STEMI. Ventricular arrhythmia, reinfarction, the need for cardiopulmonary resuscitation, target vessel revascularization, congestive heart failure, and cardiovascular mortality during index hospitalization were defined as MACE.

Results

Three hundred and eighty patients (19.7%) reached the combined endpoint with MACE. The rates of inhospital mortality and MACE were significantly higher in low EOS% group as compared to high EOS% group (4% vs. 1.1%, p < 0.01 and 32.8% vs. 11.3%, p < 0.01, respectively). On multivariate logistic regression analyses, EOS% (OR = 0.44, p < 0.01) was found to be one of the independent predictors of MACE. The EOS% lower than 0.60 on admission predicted inhospital MACE with a sensitivity of 68% and a specificity of 72% (AUC: 0.684, p < 0.01).

Conclusions

Low EOS% on admission may be associated with high inhospital MACE in STEMI patients. EOS% may be used as a novel biomarker for risk stratification of these patients.

In this paper, zinc oxide (ZnO) nanoparticles were prepared by solvothermal method. A mixture of ZnO nanoparticles and GO, surfactants, binders are dispersed in aqueous solvent. This suspension was then used as the ink for the modified 3d printer to coat on the graphite substrate to form electrodes. The GO/ZnO film has a specific capacitance of 119.9 F/g at a scan rate of 5 mV/s of CV test. The specific discharge capacitance was 153.9 F/g and retained 94.5% after 3000 cycles of galvanostatic charge-discharge (GCD) measurement with a current density of 15 mA/cm2.

Biodiesel that is produced from renewable resources has been rising as a promising candidate to replace conventional energy. Vietnam, with a large amount of land used in agriculture or forestry, has advantaged conditions to produce and develop renewable energy from biomass resources. However, developing biodiesel from agricultural product may affect food security significantly. Therefore, Jatropha that is inedible and waste cooking oil (WCO) could be suitable to biodiesel production. One of the most important aims of using biodiesel to replace fossil diesel is to reduce environmental impacts, particularly impact on Climate Change. It is necessary to analyze the environmental performance of biodiesel through the entire life cycle. In this paper, life cycle assessment of biodiesel production and use was applied to measure the environmental performance of biodiesel produced from jatropha oil and WCO under Vietnam conditions. Some main emissions, such as CO2, NOx, PM, CH4, VOC and land use, were computed through a cradle-to-grave analysis. The result shows that when using Jatropha biodiesel to replace diesel, global warming potential (GWP) and photochemical oxidant formation potential (POFP) could be improved, but some other impacts, such as acidification potential (AP) and eutrophication potential (EP), could tend to increase. The environmental impacts of WCO biodiesel are all reduced in comparison with fossil diesel.
SCHEDULING FOR MASSIVE MIMO USING CHANNEL AIGING UNDER QOS CONSTRAINTS
Authors: Hung Pham , Dang Bac Hoai , Nguyen Ban Tien
Published: October 2019

Massive multiple-input multiple-output (MIMO) networks support QoS (Quality of Service) by adding a new sublayer Service Data Adaption Protocol on the top of Packet Data Convergence Protocol layer to map between QoS flows and data radio bearers. In downlink for Guaranteed Bit Rate (GBR) flows, the gNB guarantees the Guaranteed Flow Bit Rate (GFBR) that defines the minimum bit rate the QoS flow can provide. So, one of the most important requirements is the minimum rate. The channel aiging helps to improve the sum-rate of Massive MIMO systems by serving more users to increase the spatial multiplexing gain without incurring additional pilot overhead. In this paper, a novel scheduler, termed QoS-Aware scheduling, is designed and proposed for Massive MIMO to use the channel aiging to increase the sum-rate but guarantee the minimum bit rate per user to support QoS. We investigate how many users are enough to serve to maximize the sum-rate while keeping the data rate per user meeting a given threshold. Through the numerical analysis we confirmed that QoS-Aware scheduling can guarantee a minimum rate per user and get a higher useful through-put (goodput) than conventional channel aiging schedulers.

Milliyetçilik Anlayışının; Atatürk Dönemi Türk Yönetim Sistemine Yansımaları
Authors: KANTAR Gökmen
Published: October 2019

Milliyetçilik düşüncesi, modern çağda
sanayi devrimi ile birlikte 19.yy’ın sonlarına doğru Avrupa’da ortaya
çıkmıştır. Milliyetçilik akımının etkisi, tarihine ve kültürüne önem veren,
Türklerde de tesirli olmuş, Cumhuriyet dönemiyle birlikte milliyetçilik daha da
yaygınlaşmıştır. Türkiye Cumhuriyeti’nin kurucusu Mustafa Kemal Atatürk’te
milliyetçiliği ülkü edinmiştir. Özellikle milli mücadele döneminde Türk
Milliyetçiliğine ve bağımsız yaşama azmine vurgu yapılmıştır. Bu milli şuur
üzerine kurulan Cumhuriyet ve inkılâplar milliyetçilik tabanına göre
konumlandırılmıştır. Bu temelin esası Türk Milletini, dünya uygarlık âlemi
içerisinde modern ve milli medeniyet seviyesine ulaştırmaktır. Bu çalışmanın
amacı, Atatürk’ün düşüncelerinin temeli olan milliyetçilik fikrini siyasi,
tarihi ve yönetimsel açıdan değerlendirerek; Türkiye Cumhuriyeti’nin kuruluş
döneminde milliyetçilik ilkesinin, Türk yönetim sistemine yansımalarını
incelemektir.

Osmanlı
kadın tarihi üzerine yapılan çalışmaların sayısı her geçen gün biraz daha
artmaktadır. Bu çalışmalar sayesinde, tarihte Osmanlı kadınının toplum içindeki
yerleri ve rolleri hakkında bilgi edinilmektedir. Osmanlı kadın tarihi üzerine
yazılan yazılar genellikle, kadınların ekonomik anlamda toplumsal üretime
katkıları, sosyal alandaki varlıkları ve kadınların hukuksal haklarını
kullanımı üzerinedir. Osmanlı toplumunda hukukun ve geleneklerin erkek iktidarına
öncelik tanımasına rağmen kadınların kendilerine tanınan hakları kullandıkları bilinmektedir.
En önemli hukuksal haklardan biri kadınların mahkemeye başvurabilmeleridir. Bu
anlamda, Osmanlı kadınının bizzat kendileri ya da vekilleri aracılığıyla mahkemeyi
sık sık kullandıkları bilinmektedir. Çalışmada, mahkeme ve kadın ikilemi
üzerinden kadınların mahkemeyi neden ve nasıl kullandıkları anlatılacaktır.
Çalışmanın ana kaynağı 210 Numaralı Kastamonu Şer’iyye Sicilidir. Sicil,
1732-1733 tarihlidir. Buna göre Kastamonu mahkemesi özelinde 1732-1733 yılları
arasında bir yıllık süreçte kadınların mahkemeye yansıma süreci çalışmanın
konusudur. Sicil, tarandığında belgelerin yaklaşık %80’inde kadınların var
olduğu görülmüştür.

AMAÇ:Karın
ön duvarı hernileri (ventral herniler) arasında yer alan insizyonel herniler,
karında uygulanan cerrahi girişimlerden sonra % 2 ile % 11 sıklık oranları ile
bildirilmektedir. Bu çalışmadaki öncelikli amaç, insizyonel herni risk
faktörlerini araştırmak ve yapılan karın operasyonu sonrası ilk bir yıl içinde
insizyonel herni gelişimi ile bir yıldan sonra insizyonel herni gelişimi
arasında bu risk faktörlerini karşılaştırmaktır.GEREÇ
VE YÖNTEM:İnsizyonel
herni nedeniyle opere edilen 46 hastanın ilk ameliyatının insizyon şekli, acil
veya elektif şartlarda yapılıp yapılmadığı, hastanın yaşı, cinsiyeti, body mass
indexi (BMI), yara yeri enfeksiyon varlığı, postoperatif pulmoner
komplikasyonlar ve abdominal distansiyonu arttırıcı etkilerinden dolayı kronik
obstruktif akciğer hastalığı (KOAH), sigara içim öyküsü; konstipasyon ve
prostatizm retrospektif olarak değerlendirilmiştir. Hastanın ilk ameliyatından
sonra insizyonel herni gelişinceye kadar geçen süre bir yıldan kısa ise erken,
bir yıldan uzun olanlar geçe insizyonel herni oluşan grup olarak
tanımlanmıştır. BULGULAR:Yapılan
değerlendirme sonucunda erken 30 (%65,2), geç 16 (%34,8) insizyonel herni
oluşan hasta mevcuttu. Herni oluşum zamanlamasına göre iki grup arasında yaş
ortalaması bakımından istatistiksel bir fark olmamasına (p:0,057) rağmen, geç
dönem insizyonel herni oluşan hasta yaş ortalamasının daha düşük oluşu dikkat
çekicidir. Diğer risk faktörleri arasında bir fark bulunamadı. Ayrıca insizyonel
herni oluşumunda 60 yaş altı, kadın cinsiyet, obezite ve elektif cerrahi
girişim çalışmamızda insizyonel herni risk faktörü olarak bulunmuştur.SONUÇ:

İnsizyonel
herni oluşumunda literatürden farklı olarak kadın cinsiyet, genç yaş, elektif
cerrahi risk faktörleri olarak bulunmuş olup, insizyonel herni oluşum
zamanlamasına göre risk faktörlerinde arasında herhangi bir fark yoktu.
