The diversity of unique style in the world of fashion encourages the development of textile industry in Indonesia. The textile industry that is closely related to the dyes contributes negative impact to the environment that’s water pollution. Based on previous research, egg shells and rice husk commonly discarded, turn out can be modified as an adsorbent for waste water treatment. In this research, chicken egg shells combined with rice husk and varied mass ratio are prepared for adsorbent. The preparation of adsorbent through stages of rinsing, draining, powdering, and filtering. Egg shells powder have fine texture, white and brown color due to the outer layer of the egg shells, and chicken egg shells powder’s scent. Ciherang rice husk from Bojonegoro have smooth texture, grayish brown color, and the scent of rice husk powder. Based on the results of FTIR analysis, chicken egg shells have the carbonate mineral’s peak at wave number about 1413.87-1427.37 cm -1 , also amine at 3367.82-3504.77 cm -1 , and rice husk has -OH functional group at 3367.82 cm - 1 also –C=O at 1649.19 cm -1 , which can play an important role in the adsorption process. The combination of chicken egg shells without membrane heated at T=105°C and rice husk with a 1:1 ratio showed the peak of carbonate mineral, amine, –OH, and –C=O. So, chicken egg shells and rice husk are very potential used as adsorbent because of their functional group and their existence in nature are also easy to find, abundant, and economic.

The increasing availability of high-dimensional, fine-grained data about human behavior, gathered from mobile sensing studies and in the form of digital footprints, is poised to drastically alter the way personality psychologists perform research and undertake personality assessment. These new kinds and quantities of data raise important questions about how to analyze the data and interpret the results appropriately. Machine learning models are well-suited to these kinds of data, allowing researchers to model highly complex relationships and to evaluate the generalizability and robustness of their results using resampling methods. The correct usage of machine learning models requires specialized methodological training that considers issues specific to this type of modeling. Here, we first provide a brief overview of past studies using machine learning in personality psychology. Second, we illustrate the main challenges that researchers face when building, interpreting, and validating machine learning models. Third, we discuss the evaluation of personality scales, derived using machine learning methods. Fourth, we highlight some key issues that arise from the use of latent variables in the modeling process. We conclude with an outlook on the future role of machine learning models in personality research and assessment.
Exponential-Family Random Graph Models for Multi-Layer Networks
Authors: Krivitsky Pavel N , Koehly Laura , Marcum Christopher Steven
Published: August 2019

Multi-layer networks arise when more than one type of relation is observed on a common set of actors. Modeling such networks within the exponential-family random graph (ERG) framework has been previously limited to special cases and, in particular, to dependence arising from just two layers. Extensions to ERGMs are introduced to address these limitations: Conway--Maxwell-Binomial distribution to model the marginal dependence among multiple layers; a "layer logic" language to translate familiar ERGM effects to substantively meaningful interactions of observed layers; and non-degenerate triadic and degree effects. The developments are demonstrated on two previously published data sets.
A Reading of Alexander Motyl’s Fall River Through the Lenses of Bordermemories
Authors: Ostapchuk Tetiana
Published: August 2019

This paper examines the concepts of borderlands, borderscapes, and bordermemories as cultural discursive practices that have been extensively presented and analyzed in an increasing number of theoretical works in Border Studies. Contemporary American Ukrainian writers have made attempts to introduce their hybrid experience and include it into American culture. One of them is Alexander J. Motyl, whose novel Fall River (2014) is analyzed as an example of border writing. The novel is based on the author’s narrative memory, rooted in his mother’s stories about Ukraine and their family members’ crossings of borders in the interwar period and belonging to two cultures, Ukrainian and American, that shaped their identities.

Income Inequality Across the Rural-Urban Continuum in the United States, 1970-2016
Authors: Thiede Brian C. , Butler Jaclyn L.W. , Brown David L. , Jensen Leif
Published: August 2019

Since the 1970s, the U.S. has experienced dramatic increases in income inequality. Although this macro-level trend is well-established in research literature, less is known about subnational patterns of income inequality in the U.S., particularly as they vary between and within rural and urban localities. Using Census and ACS data, this study produces Gini estimates of within-county income inequality and examines these trends across a six-strata urban-rural typology from 1970 to 2016. This study finds the following. Income inequality has remained consistently higher in nonmetropolitan counties than metropolitan counties throughout the study period. However, levels of inequality have converged by 2016, a convergence that has been driven by increases in metropolitan counties. There are notable exceptions to the secular trend of increasing inequality. The central Plains region has experienced decreasing levels of inequality, and inequality in large, peripheral metropolitan counties lags noticeably behind other types of counties. Almost all low-inequality counties in 1970 have shifted to moderate- or high-inequality, such that almost no one lives in low-inequality places by 2016. This increase in exposure to inequality has been particularly dramatic among residents of large, central metropolitan counties. As the only county-level analysis to track income inequality across the rural-urban continuum from 1970 to 2016, this study lays the foundation for more sophisticated analyses that explain spatial variation in income inequality and that account for the demographic and economic diversity of the rural and urban United States.

Authors: DE SOUZA JAQUELINE
Published: August 2019

Leishmaniasis is considered public health matter, where the interaction of several factors affects a significant amount of species. It is a chronic disease, which has as vector the Lutzomyia mosquito, inoculating the parasite Leishmania sp in the hosts when in its blood supply, this disseminated rapidly, taking advantage of immunosuppression and parasitizing previously unreported tissues. In this case report will be described the involvement by the parasite in the tissues of the mammary lesions, in a dog of 4 years, presenting vulvar swelling and lesions in the inguinal breasts. Tests were performed as a hemogram and biochemical profile, complementing with oncological cytologies of lesion sites. Some changes were observed as normocytic normochromic anemia, hyperproteinemia, and the concomitant presence of the parasite Hepatozoon canis, both in the blood and cytologic smear. In the cytologic smear, it was verified the compatibility with the Canine Transmissible Venereal Canine tumor (TVTC) and the mammary lesion, an inflammatory process, with pleomorphism, atypias, large amount of neutrophils and macrophages parasitized by amastigotes forms of Leishmania sp. The involvement of the parasite in tissues not yet reported, shows that it is opportunistic, use immunosuppression to spread more quickly, and a more careful investigation of the lesions present in the patients is necessary.

Published: August 2019

Bovine cryptosporidiosis is caused mainly by the following species of the genus Cryptosporidium: Cryptosporidium parvum, Cryptosporidium bovis, Cryptosporidium andersoni and Cryptosporidium rynae. The appearance of clinical signs in infected cattle is directly correlated to the age, host immune status and the parasite species responsible for the infection. Diarrhea is the most evident clinical sign during bovine cryptosporidiosis, and it is usually observed in newborn calves infected with C. parvum. Of all species of the genus Cryptosporidium that affects cattle, C. parvum is the only one that is known to have zoonotic potential. Bovine animals, when infected by this species, excrete large amounts of oocysts of the parasite in the environment, a very important factor in the epidemiology of this coccidiosis. The absence of effective drugs and vaccines against Cryptosporidium spp. in cattle, point to the need for prophylactic measures aimed at the proper management of animals. The objective of this review was to elucidate the clinical, epidemiological and therapeutic aspects of cryptosporidiosis in cattle.

Cardiopulmonary resuscitation (CPR) should be started promptly in a situation of cardiorespiratory arrest (CRP). The Reassessment Campaign on Veterinary Resuscitation (RECOVER) proposes clinical recommendations for the application of the procedure in dogs and cats and also recognizes the need for cognitive and psychomotor skills to perform the entire protocol in an agile and efficient manner. In this way, an ideal training should cover didactic components and practice of manual skills, with the use of discriminated models and simulators. The use of alternative methods with synthetic models is supported by the increase in concerns about animal welfare, a demand that is presented by Veterinary Medicine scholars and residents of the Veterinary Hospital of the Federal University of Paraná (UFPR). In addition to the high cost of commercially available models, the objective of this work is to present a low-cost model for training CPR in dogs. After acquisition of a plush dog, a representative structure of the internal part of the chest was elaborated with a plastic packaging of powdered chocolate filled with silicon fiber. Then, the larynx cartilages were produced in silicone rubber of medium flexibility, adhered to a corrugated trachea. The molds of the hard palate and upper and lower dental arches were made of resin, painted with acrylic paint and fixed to a modified dental articulator. For the oral mucosa and tongue it was made low viscosity silicone elastomer structures. The model allowed to perform the procedures of thoracic compression and endotracheal intubation, steps included in the CPR. The model was tested by Veterinary Medicine professionals with experience in CPR, and a good result was reported. The presented CPR model allowed the simulation of the basic support to life and, being of low cost, can be made by other educational institutions with this same purpose.

Art is a way of understanding life and the world and manifesting about them, animals were essential to the construction of the civilization of the human species, nothing more just that they be in human artistic and cultural manifestations. According to the guidelines for the curricula of veterinary medicine courses, there is a need to make the graduates have more human and social skills, with awareness of the reality and its importance for society. The proposal would then be to use various forms of arts to discuss in the form of literature review in the classroom the subjects they bring up, so as to foster dialogue and individual opinions and scientific knowledge. In this article will be seen books: Vidas Secas (Gracialiano Ramos, 1938) and Gaúcho de José de Alencar (1870); the Heartland series (CBC, 2007-present); the songs Poncho Molhado (José Claudio Machado) and Atirei o Pau no Gato (traditional and new- Public Domain) and the films of Rio 2 (20o Century FOX, 2014) and Touro Ferdinando (20o Century FOX, 2016). It can be suggested that through the arts one can reflect the animal, the human-animal relationship and its consequences.

The Influence of Brass Compensator Thickness and Field Size on Neutron Contamination Spectrum in 18MV Elekta SL 75/25 Medical Linear Accelerator with and without Flattening Filter: A Monte Carlo Study
Authors: Talebi A S , Maleki M , Hejazi P , Jadidi M , Ghorbani R
Published: August 2019

BackgroundOne of the most significant Intensity Modulated Radiation Therapy treatment benefits is a high target to normal tissue dose ratio. To improve this advantage, an additional accessory such as a compensator is used to delivering doses. Compensator-based IMRT treatment is usually operated with an energy higher than 10 MV. Photoneutrons, which have high linear energy transfer and radiobiological effectiveness, are produced by colliding high-energy photon beams with linear accelerator structures, then they deliver the unwanted doses to patients and staff. Therefore, the neutron energy spectra should be determined in order to calculate and reduce the photoneutron risk.Objective: We have conducted a comprehensive and precise study on the influence of brass compensator thickness and field size on neutron contamination spectrum in an Elekta SL 75/25 medical linear accelerator with and without the flattening filter by Monte Carlo method.Materials and Methods: MCNPX MC Code version 2.6.0 was utilized to simulate the detailed geometry of Elekta SL 75/25 head components based on Linac’s manual. This code includes an important feature to simulate the photo-neutron interactions. Photoneutrons spectrum was calculated after the Linac output benchmarking based on tuning the primary electron beam.Results and Conclusion: Based on the Friedman and Wilcoxon nonparametric tests results (P<0.05), photoneutron fluence directly depends on the field size and compensator thickness. Moreover, the unflattened beam provides lower photoneutron fluence than the flattened beam. Photoneutrons fluence is not negligible in compensator-based IMRT treatment. However, in order to optimize treatment plans, this additional and unwanted dose must be accounted for patients.

Published: August 2019

Bystander or non-targeted effect is known to be an interesting phenomenon in radiobiology. The genetic consequences of bystander effect on non-irradiated cells have shown that this phenomenon can be considered as one of the most important factors involved in secondary cancer after exposure to ionizing radiation. Every year, millions of people around the world undergo radiotherapy in order to cure different types of cancers. The most crucial aim of radiotherapy is to improve treatment efficiency by reducing early and late effects of exposure to clinical doses of radiation. Secondary cancer induction resulted from exposure to high doses of radiation during treatment can reduce the effectiveness of this modality for cancer treatment. The perception of carcinogenesis risk of bystander effects and factors involved in this phenomenon might help reduce secondary cancer incidence years after radiotherapy. Different modalities such as radiation LET, dose and dose rate, fractionation, types of tissue, gender of patients, etc. may be involved in carcinogenesis risk of bystander effects. Therefore, selecting an appropriate treatment modality may improve cost-effectiveness of radiation therapy as well as the quality of life in survived patients. In this review, we first focus on the carcinogenesis evidence of non-targeted effects in radiotherapy and then review physical and biological factors that may influence the risk of secondary cancer induced by this phenomenon.
Intellectual endogamy in the university
Authors: Muñoz-García Ana Luisa
Published: August 2019

This article aims to analyse the multiple ways in which the neoliberal regulation of knowledge is negotiated by returning Chilean scholars. The data gathered suggest the construction of knowledge is highly regulated by a principle of intellectual endogamy. Intellectual endogamy is characterised by conservatism, reflected in a lack of diversity in research themes and problems and maintained by a peer-review system that controls scholars’ access to research funds. However, it is also characterised by instrumentalism, which is reflected in the requirements for obtaining research funds, such as publications in indexed journals and discourses of efficiency and productivity. Both facets engender a neoliberal regulation of academic work. This research encourages an expansion of the conversation about how academic mobility affects knowledge construction.
A longitudinal comparison of information literacy in students starting Politics degrees
Authors: Thornton Stephen
Published: August 2019

Information literacy, the concept most associated with inculcating the attributes necessary to behave in a strategic, thoughtful and ethical manner in the face of a superfluity of information, has been part of the information specialist scene for many years. As the United Kingdom’s QAA benchmark statements for Politics and International Relations highlight, many of the competences associated with this concept are vital in the honourable struggle to become a successful graduate of those disciplines. This article presents a longitudinal study of a survey used to expose the information literacy levels of two groups of first-year Politics/IR students at a British university and, using the logic of ‘most similar design’, make informed inferences about the level of students’ information literacy on coming into tertiary education.

Nowadays, autonomous systems that incorporate renewable energy sources and energy storage systems play a fundamental role as a solution to energy supply problems. These systems are a good alternative, mainly in remote areas of the electricity network such as islands. This paper analyzes the cost of battery life, operation and maintenance costs and the uncertainty costs associated with renewable energy agents for an autonomous microgrid developed on Dong-fushan Island in China, all in order to obtain the adequate parameters for the optimum operation of the same, without forgetting the characteristics of useful life in specific lead-acid batteries. It is intended, through the non-dominant algorithm of genetic classification (NSGA II), to achieve maximization of the aforementioned variables: useful life of the batteries, and the reduction of the generation cost, proposing a multi-objective optimization. In addition to the above, the costs of uncertainty associated with renewable wind energy are included.

Authors: Caicedo Ramírez Camilo Ernesto , Pabón Andrade Álvaro Javier , Mirama Pérez Víctor Fabián
Published: August 2019

The ubiquity and wide deployment of wireless local area networks (WLAN) have increased the inherent risk of interference. Numerous studies have shown that power control is an efficient alternative to deal with interference and an outstanding framework for modeling scenarios in which user equipments perform power control is game theory. However, the research in this field has focused on the theoretical analysis and system-level simulations given the complexity of implementing power control in a real environment. This paper shows the implementation of a power control algorithm for WLAN based on game theory (GT), specifically, the IEEE 802.11.a standard using software defined radio (SDR) platforms and reconfigurable hardware. The results show that the algorithm significantly increases the energy savings and energy efficiency of the stations (STA) and decreases the interference. The interference reduction improves the overall network performance, decreasing the FER, and increasing the throughput.

Abstract: This research is motivated by the fact that not all consumers behave rationally. There are still many consumers who behave iirationally in the form of consumptive behavior. Consumers in this case students who have consumptive behavior are suspected because consumers are lacking in economic literacy. The purpose of this study was to determine the effect of economic literacy on student consumptive behavior at STKIP Persada Kahtulistiwa Sintang. The research method used is quantitative with factual exposures. The population is students with 257 people. The sampling technique used is Simple Random Sampling with a sample size of 65 people. Data collection tool in the form of questionnaires and test questions. The results showed that economic literacy had a negative and significant effect on students' consumptive behavior in STKIP Persada Khatulistiwa Sintang. This is confirmed by the results of the t test which shows the value of t count - 3,400> t table - 1,998 (Two Tailed) on df = n -2 = 65 - 2 = 63 and the error rate (α = 5%) or significance 0,000 <0.05 means null hypothesis is rejected and alternative hypothesis is accepted. Keywords: Economic Literacy, Consumptive Behavior Abstrak: Penelitian ini dilatarbelakangi oleh kenyataan yang terjadi bahwa tidak semua konsumen berperilaku rasional.

SUSCETIBILIDADE MORFOMÉTRICA A INUNDAÇÕES NAS BACIAS HIDROGRÁFICAS TRIBUTÁRIAS DO RIO DO PEIXE, ZONA DA MATA DE MINAS GERAIS
Authors: Ávila Bárbara Thaís , Almeida Neto José Oliveira de , Felippe Miguel Fernandes
Published: August 2019

As inundações são processos naturais que estão relacionados, entre outros fatores, às características morfométricas que representam a geometria do relevo da bacia hidrográfica. Ou seja, sabe-se que o conjunto das feições do relevo em uma bacia pode contribuir para escoar de modo mais rápido ou mais lento suas águas superficiais, condicionando (ou não) a ocorrência de cheias, em associação aos fenômenos meteorológicos. Diante disso, esse trabalho tem como objetivo avaliar a suscetibilidade morfométrica a inundações de 23 bacias tributárias (8ª, 7ª, 6ª e 5ª ordens), que compõe a bacia hidrográfica do rio do Peixe, no sudeste de Minas Gerais.  Foram utilizadas as bases ottocodificadas, da rede de drenagem e das bacias de drenagem, além de curvas de nível na escala de 1:50.000, para o cálculo de quinze parâmetros morfométricos. Posteriormente, realizou-se a interpretação qualitativa multivariada de cada unidade de análise para definição de graus de suscetibilidade a inundações. O mapeamento dos resultados permite uma leitura comparativa da distribuição espacial das suscetibilidades. Além disso, demonstra-se que a forma da bacia, o índice de circularidade e o fator de forma foram os parâmetros que sinteticamente melhor traduziram os resultados da composição multivariada. Essa metodologia apresentou-se como passível de ser empregada em zoneamentos ambientais de bacias hidrográficas para que se elabore um planejamento que seja mais condizente com as reais possibilidades que os tributários têm de contribuir para a ocorrência de inundações em bacias de maior hierarquia.

COMPETITIVIDADE REGIONAL DO SETOR SUCROENERGÉTICO NO TRIÂNGULO MINEIRO/ALTO PARANAÍBA
Authors: Santos Henrique Faria dos
Published: August 2019

O presente artigo objetiva analisar a competitividade regional do setor sucroenergético no Triângulo Mineiro/Alto Paranaíba a partir da identificação e análise de alguns fatores (naturais, geoeconômicos e político-normativo-institucionais) que conferem maior produtividade e fluidez aos agentes. No atual período da globalização, a localização geográfica tem se tornado uma estratégia cada vez mais importante para que as grandes empresas se insiram e se mantenham nos principais mercados nacionais e internacionais. Isto porque o ganho de competitividade não depende apenas das condições internas das firmas, mas também de fatores externos que assegurem a eficiência das atividades (produção e logística). Para tanto, regiões, territórios e lugares são chamados a participar deste processo, disponibilizando condições geográficas ideais que proporcionem melhores qualidades e custos dos produtos e/ou serviços. É o caso, por exemplo, do Triângulo Mineiro/Alto Paranaíba, uma das principais Regiões Produtivas do Agronegócio Canavieiro do país. A pesquisa bibliográfica, documental-estatística e trabalhos de campo permitiram verificar que a recente expansão do setor sucroenergético na área de estudo decorre, em grande parte, da existência de algumas condições produtivas e logísticas que resultam em maior competitividade dos agentes, principalmente na porção regional a qual denominamos de Região Competitiva Agroindustrial do Setor Sucroenergético (RCASS) de Uberaba-Frutal.
NA MEMÓRIA DAS MARIAS: HISTÓRIA ORAL, MIGRAÇÕES, GERAÇÕES E LUGAR NO CONTEXTO DE FORMAÇÃO DO ASSENTAMENTO TUCANO EM EUCLIDES DA CUNHA PAULISTA/SP

Published: August 2019

Este artigo tem como objetivo discorrer sobre o processo de formação do Assentamento Tucano, localizado no município de Euclides da Cunha Paulista, no oeste do Estado de São Paulo, região conhecida como Pontal do Paranapanema, na qual há uma longa história de conflitos fundiários e de criação de assentamentos rurais. Pretende-se através do artigo apresentar o processo de luta e conquista pela terra sob o viés feminino, através de lembranças e relatos de mulheres que participaram desse processo e também das jovens que ressignificam a história de avós e pais como um reforço de identidade com o grupo de pessoas que integram o assentamento e com a terra na qual vivem e produzem, fortificando o sentimento de pertencimento ao lugar. Os principais procedimentos metodológicos utilizados na pesquisa foram as entrevistas temáticas e de história oral.
NOVOS MODOS DE MORAR E CONSUMIR E A PRODUÇÃO DA DIFERENCIAÇÃO SOCIOESPACIAL EM CATANDUVA E SÃO JOSÉ DO RIO PRETO - SP
Authors: Milani Patricia Helena
Published: August 2019

O cotidiano, enquanto unidade de espaço e tempo é nossa dimensão de análise, tendo as práticas espaciais dos sujeitos sociais pesquisados – moradores de espaços residenciais fechados de Catanduva e São José do Rio Preto - SP- enquanto plano analítico. Isso nos permitiu identificar como o processo de diferenciação socioespacial se expressa na produção do espaço urbano, sobretudo a partir dos espaços vividos e representados, conferindo sentidos e significados às práticas, que envolvem relações contraditórias entre espaços internos e externos, fechados e abertos. Com base na realização de 22 entrevistas e em observações de campo, a pesquisa revelou que, sob o discurso da busca por segurança, os sujeitos pesquisados de classe média e elite, valorizam e produzem estratégias de distinção socioespacial, nas quais o espaço urbano é dimensão estratégica, haja vista que, em uma cidade com número elevado de espaços residenciais fechados e shopping center, como São José do Rio Preto, apenas morar e consumir em um deles não é distinção suficiente, é necessário ainda indicar em qual deles. Em Catanduva há permanências das práticas tradicionais de consumo, no centro principal, porém, quando operamos a partir do processo de articulação escalar, levando em conta as práticas de consumo dos entrevistados de Catanduva que frequentam certos shopping centers de São José do Rio Preto, verifica-se que a produção da diferenciação socioespacial também se efetiva. Tal busca modifica as maneiras como esses sujeitos sociais vivenciam o urbano e aquilo que lhe é inerente, sendo a cidade cada vez mais vivida e representada em fragmentos, sobretudo entre as áreas norte e sul de São José do Rio Preto.
