Dramatic Irony as an Intervention Strategy in Two Dholuo Films: Kalausi and The Cleansing
Authors: Odhiambo Christopher , Maseno Loreen
Published: June 2019

Kalausi and The Cleansing are two films set in Kenya whose storylines touch on death and rituals among the Luo community of Kenya. Both films are in the language of Dholuo and place sharp focus on widowhood and its prevailing dilemmas and anxieties within Luo culture. It is these dilemmas and anxieties that reveal the injustices that culture metes out to women. While Kalausi engages its viewers up until the burial ceremony, The Cleansing starts after the actual burial and focuses on post-burial rituals. Thus, the two films in a way complement each other in the presentation of the injustices and intrigues that a woman faces during and after the demise of a spouse. Dramatic irony as the trope of ambiguity in the two films builds up tension, suspense and comic relief. Consequently, we examine how dramatic irony participates as a socio-cultural device of intervention in the two films. Reading the two films from this perspective, dramatic irony as a signifying trope becomes paramount in unravelling the multiplicities of interpretations evident in the critical moment of death within the Luo community. It is an extremely intricate signifying device as it plays on the contrast between reality and appearance.

ENDOCARP ANALYSIS OF A TRADITIONAL VARIETY OF COLOMBIAN COFFEE
Authors: MUÑOZ MILTON , ROA MANUEL , CORREA RODRIGO
Published: June 2019

 This article presents the main results of thermal analytical and drying tests applied to the endocarp of coffee bean samples, in order to analyze their influence on the coffee dehydration process. An infrared analysis, as well as TGA, DTGA and DSC tests, were applied to the parchment of a sample of Castilla variety coffee beans and later compared with similar tests performed on coffee beans of the same variety, upon parchment removal. For analytical tests, the main thermogravimetric transitions are reported up to a temperature of 1000 °C. From thermograms, four temperature range were identified for parchment, with their respective mass loss: 33-33.7°C, 9.48%; 33.7-251.2°C, 16.23%; 251.2-358°C, 47.48%; and 358-800°C, 15.52%. The greatest mass loss was due to cellulose and hemicellulose degradation. The study was complemented by drying experiments on samples of beans with and without parchment. The diffusion coefficients were found using Fick’s second law and metaheuristic optimization methods (global optimization). On average, the diffusion coefficient of grains without endocarp is 46% greater than that of beans dried with the parchment. Coffee beans with parchment took, on average, 50% more time to reaching moisture levels of 12% (on dry basis). The results are considered important for the projection and design of new coffee drying systems and their automatic control.

Authors: Da Silva Paulo Vinicius , Barbosa Gustavo César , Ferrari Andréa , Tronquini Sergio Mateus , Monquero Patrícia Andrea
Published: June 2019

 The present study aims to evaluate the control of C. benghalensis by herbicides applied in post-emergence and in pre-emergence sequentially in the infesting weed in the coffee crop. Two field experiments were carried out in a coffee crop, with natural infestation of C. benghalensis, the experimental design of both was completely randomized with 4 replicates. The first experiment, involving a single application of herbicides in post-emergence presented the following treatments: (1) saflufenacil (70 g i.a. ha-1); (2) glufosinate (400 g i.a. ha-1); (3) carfentrazone (20 g i.a. ha-1); (4) flumioxazin (120 g i.a. ha-1); (5) metsulfuron (6 g i.a.  ha-1), and (6) witness (without application of herbicide). In the second experiment, the treatments were: (1) saflufenacil (70 g i.a.  ha-1); (2) carfentrazone (20 g i.a. ha-1); (3) flumioxazin (120 g i.a.  ha-1); (4) metsulfuron (6 g i.a.  ha-1), all these treatments with a sequence of indaziflam (75 g i.a.  ha-1), at 21 days after the application of the treatments (DAT) of pos-emerging; (5) Witness (without application of herbicides). In the first experiment the herbicides safluenacil and flumioxazin presented the best percentages of control in post-emergence with 90 and 85.25% respectively, at 7 DAT, keeping the control superior to 80% at 21 DAT. In the second experiment, the treatments saflufenacil and flumioxazin with indaziflam sequential, presented control of 80% and 82.5% respectively at 28DAA (Days After Application). The herbicides saflufenacil and fluxioxazin represent an option for the control of C. benghalensis in post-emergence and favor the performance of the sequentially applied indaziflam herbicide.

Authors: KARAOĞLU Nazlı
Published: June 2019

Türkiye Akdeniz’e kıyısı olan, tarihi ve kültürel dokusuyla dikkat çeken önemli turizm destinasyonlarından biridir. Yabancı turistler sayesinde turizm sektörü Türk ekonomisine döviz getirisi sağlayan sektörlerin başında gelmektedir. Bu çalışmanın amacı Türkiye’nin uluslararası turizm talebini belirleyen faktörleri ortaya koymaktır. Bu amaçla, Türkiye’ye turist gönderen 24 ülkenin 2010-2017 yıllarına ilişkin verilerinden yararlanılmıştır. Uluslararası turizm talebini temsilen ülkeye gelen yabancı turist sayısı kullanılmıştır. Modelde turist tercihlerinin değişen yapısı dikkate alındığı için dinamik panel veri analizi uygulanmıştır. Bağımlı değişkenin gecikmeli değerinin açıklayıcı değişken olarak modele eklenmesi sayesinde turistlerin sadakati ve tavsiyeleri ölçülebilmektedir. Bir dönem önceki turizm talebinin, kişi başı gelirin, arz kapasitesinin ve Türkiye’deki politik istikrarın turizm talebini olumlu etkilediği; göreli fiyat, terör olayları ve 2016’daki darbe girişiminin turizm talebini olumsuz etkilediği; nispi döviz kurlarının ise turizm talebini etkilemediği saptanmıştır.

Authors: De Carvalho Érica Rios
Published: June 2019

Este artigo é uma atualização do já publicado “Gestão municipal do SUS e seus impactos na prestação dos serviços de saúde – o caso de Salvador/BA entre 2010 e 2013”. Sua intenção é retomar o traçado do panorama da gestão do Sistema Único de Saúde (SUS) no Brasil, a partir de sua descentralização (municipalização), utilizando o Plano Municipal de Saúde (PMS) 2014-2017 de Salvador/BA como parâmetro avaliativo. No artigo já publicado sobre o plano anterior, o confronto de suas propostas com o que fora realizado na prática evidenciou descumprimentos que implicavam em diminuída efetividade dessa política pública. Para manter a coerência da comparação do plano mais recente, serão mantidos os mesmos recortes e metodologia.
É A FAVELA O MODELO DE UM "URBANISMO INSURGENTE"? PISTAS PARA UM ESTUDO DAS FORMAS DISCIPLINAR E SECURITÁRIA DE PRODUÇÃO DO ESPAÇO URBANO DE SALVADOR (1946-1988)
Authors: Nascimento Jùnior Manoel Maria do
Published: June 2019

Tendo como base a distinção entre formas disciplinares e securitárias de exercício da soberania, tal como conceituadas por Michel Foucault, este artigo pretende, a partir de uma revisão bibliográfica sobre o processo de formação do território urbano de Salvador no século XX, responder às seguintes questões: é a favela um "urbanismo insurgente"? Pode a favela constituir uma alternativa ao urbanismo oficial? Em que medida a ação dos invasores, dos "favelados", compromete este urbanismo oficial? E em que medida o reforça? Conclui-se que: a) Sim, pode ser um “urbanismo insurgente” desde que considerada como  expressão dos fenômenos da ocupação de terra urbana por massas proletárias e como conjunto de ações mais ou menos descoordenadas de sujeitos coletivos diversos; b) As invasões e favelas, sendo parcelares, não constituem uma alternativa global ao urbanismo e ao planejamento urbano oficiais, mas a proliferação de invasões e favelas num tempo histórico curto pode indicar que as muitas ações individuais e coletivas formadoras das invasões e favelas ofereceram um sentido alternativo ao desenvolvimento urbano da cidade.
ABERTURA, MANUTENÇÃO E FECHAMENTO DA CASA DE SAÚDE SANTA TERESA: TRAJETÓRIA MANICOMIAL DO CARIRI CEARENSE
Authors: Gimbo Leda Mendes , Dimenstein Magda , Leite Jader
Published: June 2019

A história da loucura no Brasil é indissociável da história dos hospitais psiquiátricos, uma vez que a organização das cidades e sua higiene, pautadas nos moldes franceses do século XIX, dependiam dessas instituições para a manutenção da ordem social. A região do Cariri cearense contou com a existência de um hospital psiquiátrico (Casa de Saúde Santa Teresa) que funcionou a partir da década de 1970. Sua inauguração não foi uma aleatoriedade, mas fruto de formações discursivas específicas e relações de saber e poder que constituíram o alicerce para que o hospital abrisse suas portas na região, bem como para se manter em funcionamento até os dias atuais. A Casa de Saúde Santa Teresa foi uma instituição privada, credenciada inicialmente ao Instituto Nacional de Previdência Social e posteriormente ao SUS, recebendo financiamento público. Sua localização geográfica favoreceu o atendimento às pessoas da região do sul do Ceará, mas também do interior dos estados de Pernambuco, Paraíba e Piauí. Até fechar contou com 200 leitos cadastrados ao SUS, atendeu em regime ambulatorial e de internamento para uma média de 400 pessoas/mês. Apesar do intenso fluxo de atendimentos e se tratar da única referência para atendimentos de urgência, emergência e para situações de crise, o hospital encerrou seus anos de funcionamento em fevereiro de 2016. Segundo dados da Casa de Saúde, não havia aumento no valor das Autorizações de Internação Hospitalar (AIHs) desde o ano de 2009, o que tornava inviável a manutenção e funcionamento do hospital. 
The Relationship between Corpus Callosum Morphometric Measurements and Age/Gender Characteristics: A Comprehensive MR Imaging Study
Authors: Arda Kemal Niyazi , Akay Sinan
Published: June 2019

Objective:

The objective of the study was to examine a possible relationship between morphometric corpus callosum (CC) measurements, age, and gender characteristics using MR images.

Materials and Methods:

The medical data and MR examinations of 436 consecutive subjects were retrospectively reviewed. The CC thickness from five different sites, and additionally splenium length, height, and total length of the CC, and the splenium index (SI) were measured with a mid-sagittal T1-weighted sequence. Those measurements were compared with age and gender characteristics.

Results:

A weak but statistically significant negative correlation was found between age and thicknesses of genu and all body portions of CC (P = ≤0.001 for all, r = -0.32 for genu, r = -0.317 for B1, r = -0.328 for B2, r = -0.328 for B2, and r = -0.194 for B3 and B4). There was a weak but statistically significant positive correlation between age and the lengths of CC and splenium (P ≤ 0.022 for both, r = 0.112 for CC length and r = 0.11 for splenium length). The second part of the body (B2) was thicker in females (P = 0.014). On the other hand, the CC and splenium lengths were greater in males compared to females (P = 0.029 for both).

Conclusion:

We designed a comprehensive MRI study to investigate a possible relationship between normal morphometric CC measurements in 436 healthy subjects. We preferred splenium length and SI as the main splenium measurements instead of direct splenium thickness, due to discrepancies regarding splenium measurement methods in the medical literature. There was a wide spectrum of results, and we compared those results with existing medical literature.
HEALTH, A STRATEGIC NATIONAL RESOURCE

Published: June 2019

Health has always been the most valuable and beautiful gift that Nature offered to humans. Unfortunately, nowadays, people value and desire more wealth than health; often they remain indifferent to the degradation of their own health. Only in front of serious diagnoses people start appreciating their true wealth – the health. The allopathic medicine has no giants’ power, as it sometimes treats symptoms and diseases instead of illnesses’ fundamental causes.Education, the other field revealing the horizon of knowledge, provides creative alternatives for spending revenues in favour of healthy individuals and societal robust development. The purpose almost remains the same: use both complex potentials and opportunities to increase motivation, accomplish joy of life and fulfil desires to build wellbeing. The link between Health and Education has complex links and hidden mechanisms waiting for to be explored and used in favour of all.
CLIMATE CHANGE AND ITS INTERACTION WITH NATURAL, ECONOMIC AND SOCIAL PROCESSES
Authors: DRAGOMIR Robert Gabriel , DRAGOMIR Lucian Octavian
Published: June 2019

Human-made GHGs work against us when they trap too much sunlight and block outward radiation. Scientists worry that the accumulation of these gases in the atmosphere has changed and will continue to change the climate. Potential climate risks include more severe weather patterns; hobbled ecosystems, with less biodiversity; changes in patterns of drought and flood, with less potable water; inundation of coastal areas from rising sea levels; and a greater spread of infectious diseases such as malaria, yellow fever, and cholera. On the plus side, climate change might benefit agriculture and forestry in certain locations by increasing productivity as a result of longer growing seasons and increased fertilization. Although climate change is not the same as day-to-day or even year-to-year fluctuations in the weather, the nature of these fluctuations could be altered by climate change.
A RELATIVE ASSESSMENT OF THE CONTRIBUTIONS OF AGRICULTURE, OIL AND NON-OIL TAX REVENUES TO NIGERIA’S ECONOMIC EXPANSION
Authors: OMODERO Cordelia Onyinyechi
Published: June 2019

The decline in oil prices globally has led to diversification of economy in most oil enriched countries.  In Nigeria, more attention is given to agriculture and non-tax revenue sources to ensure that the country overcomes a mono-economy syndrome which has affected the nation in the past.  This study assesses the contributions of agriculture, oil and non-oil tax revenue to economic expansion in Nigeria using data that cover a period from 1981 to 2017.  The regression results indicate that oil revenue has a significant negative impact on economic growth which is represented by gross domestic product.  On the contrary, the study finds evidence that agriculture and non-oil tax revenue have a robust significant and positive influence on economic growth.  Therefore, the study suggests that tax administration in Nigeria should be more business-growth conscious and that agriculture should be given a boost by creating an enabling environment that could attract foreign direct investments in the agricultural sector.  The study also recommends that oil revenues should be utilized for reinvestments into other sectors of the economy. Keywords:  Oil revenue, non-oil tax revenue, agriculture, economic growth, Nigeria.JEL Classifications: H27, H24, H25, N5, O4

Published: June 2019

Carbon nanotubes (CNTs) synthesized by chemical vapour deposition without using hydrogen were oxidized with 0.1 M potassium permanganate at 40oC for 2 hours and exhibited high CuII adsorption capacity from aqueous solution. X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), scanning electron microscope (SEM), transmission electron microscope (TEM) and nitrogen adsorption/desorption isotherms were used to characterize the oxidized CNTs. After oxidizing, the obtained CNTs were used to remove CuII from aqueous solution. With CuII initial concentration of 20 mg.L-1, at pH of 4 and adsorbent dosage of 0.2 g.L-1, the oxidized CNTs exhibited high CuII adsorption ability with maximum adsorption capacity of 174.4 mg.g-1.
Dietary restriction induces posttranscriptional regulation of longevity genes
Authors: Rollins Jarod A , Shaffer Dan , Snow Santina S , Kapahi Pankaj , Rogers Aric N
Published: June 2019

Dietary restriction (DR) increases life span through adaptive changes in gene expression. To understand more about these changes, we analyzed the transcriptome and translatome of Caenorhabditis elegans subjected to DR. Transcription of muscle regulatory and structural genes increased, whereas increased expression of amino acid metabolism and neuropeptide signaling genes was controlled at the level of translation. Evaluation of posttranscriptional regulation identified putative roles for RNA-binding proteins, RNA editing, miRNA, alternative splicing, and nonsense-mediated decay in response to nutrient limitation. Using RNA interference, we discovered several differentially expressed genes that regulate life span. We also found a compensatory role for translational regulation, which offsets dampened expression of a large subset of transcriptionally down-regulated genes. Furthermore, 3′ UTR editing and intron retention increase under DR and correlate with diminished translation, whereas trans-spliced genes are refractory to reduced translation efficiency compared with messages with the native 5′ UTR. Finally, we find that smg-6 and smg-7, which are genes governing selection and turnover of nonsense-mediated decay targets, are required for increased life span under DR.
NA ERA DA MULTIPLICIDADE: FRAGMENTAÇÃO, INTENSIDADE E VELOCIDADE NO CONTO CATÁSTROFE, DE LUIZ VILELA
Authors: Ribeiro Rondinele Aparecido , Silva Eduardo Dias da
Published: June 2019

A narrativa contemporânea, em seus múltiplos suportes, converte-se num espaço amplo e privilegiado ao retratar temáticas sociais e ficcionalizar tensões cotidianas. Como marca desse período, a literatura apresenta-se de maneira esfacelada e fragmentada revelando novas nuances e possibilidades de configuração. A partir dessas considerações iniciais, o presente artigo intenciona tecer considerações acerca dessa condição experimentada pela literatura contemporânea. Para tanto, analisará o conto Catástrofe (2002), do escritor Luiz Vilela. Identificamos nessa narrativa, as características marcantes desse cenário em que a fragmentação e a intensidade ditam a tônica das relações sociais. No conto cotejado, a expressividade se apresenta pela ausência de um narrador. Assim, o leitor é levado à apresentação dos fatos pela força constitutiva de diálogos fragmentados, intensos e velozes que desvelam um sujeito fragmentado.
Between Retributive and Restorative Compulsory School Teachers’ Discipline Activities
Authors: Jeznik Katja , Kroflič Robi , Kuhar Metka
Published: June 2019

In Slovenia, compulsory schools have, since 2009, been obliged to define their own concept of moral and character education under the formal framework of the Primary School Act. Disciplinary measures in schools are underpinned by two main punishment theories: the more traditional retributive responses to undesired conduct, and the more recent restorative approach. The present study explores the views of 109 teachers from 13 compulsory schools regarding disciplinary measures through the prism of this paradigmatic divide. A qualitative analysis of group discussions in which teachers evaluated the disciplinary measures at each of the 13 schools will be presented. Only three discussion groups were predominantly restorative oriented. Given the proven negative effects of retribution-oriented disciplinary measures, the findings are not encouraging. We conclude that schools need a clearer disciplinary framework with systematic acquisition of knowledge and practical experience in the field of educational and discipline strategies, and that teachers must continuously reflect on their own disciplinary practices.

This paper presents the background of a generic architectural model of a BC system and explains the concept behind the consensus models used in BC transactions. Security is the main aspect of all deﬁned operations and BC nodes. The paper presents also speciﬁc BC use cases to illustrate the performance of the system in practical scenarios..
Differences Exudates After Irrigation With Measured Pressure on Diabetic Ulcers
Authors: Noor Mohammad Arifin , Suyanto Suyanto
Published: June 2019

Diabetic ulcer is a further complication of the presence of diabetic ulcers that are not handled properly. Gangren ulcers are very difficult to cure. One of them is the characteristic of gangrene wounds that have a hollow (hard) that is very difficult to do cleansing. In addition, the types of bacteria that are in gangrene are anaerobic bacteria that are difficult to treat with antibiotics. The number of bacteria will also be proportional to the number of production of pus. One of the most possible actions is to irrigate the wound tunnel so that the wound is clean and anaerobic bacteria are reduced. The modern wound irrigation device, which is one of the developments of existing irrigation devices, is expected to be able to reach gangrenous wound tunnels with a modified form of output. This study aimed to determine the effect of modification of the output of the modern wound irrigation device (MWID) on the number of bacteria in diabetic gangrenous ulcer sufferers. The method used in this study was quasi-experimental without a control group. The intervention group was given wound irrigation using a modified MWID tool. The instrument was used to determine exudate production using the observation sheet Leg Ulcer Measurement Tool (LUMT). The results of the analysis by the Mc Nemar test showed that p value 0.67 (p value> 0.05) means that there is no difference in the amount of exudate production with modification of the MWID output. Further research is needed regarding the effect of irrigation angle on the number of bacteria in diabetic ulcers.

Objetivos. Determinar la composición química, características físico-químicas y el efecto genotóxico del aceite de Plukenetia volubilis L. Materiales y métodos. Se evaluó el perfil de ácidos grasos, tocoferoles, esteroles,fosfolípidos,carotenoides,tocotrienoles y fenoles; así como  las características físico-químicas y trazas metálicas. La genotoxicidad fue evaluada a través del ensayo de morfología de la cabeza de espermatozoides. Para este ensayo, se emplearon ratones albinos machos formando 3 grupos de experimentación de 7 animales cada uno: control negativo (solución salina 0,9%), control positivo (50 mg/kg/pc/día de ciclofosfamida) y grupo problema que recibió por vía oral 0,5 ml de aceite sacha inchi (NIMET); las sustancias se administraron cada 24 horas por 5 días. Resultados. El aceite contiene ácidos grasos poliinsaturados(81,72%),monoinsaturados(10,31%) y saturados(7,67%); siendo el alfa-linolénico (47,35%) y el linoleico (34,34%) los más abundantes. El  tocoferol y esterol más abundante fueron el gamma-tocoferol y el beta-siitosterol respectivamente,y en escasa cantidad se halló:  fenoles,fosfolípidos,carotenoides y tocotrienoles. Los índices de refracción, saponificación, yodo, peróxido y de acidez, fueron 1,48, 189 mg KOH/g, 190, 0,9 meq/kg, 1,11 KOH/g respectivamente. La densidad, materia insaponificable y humedad y materias volátiles fueron 0,9276, 0,27%, 0,05% respectivamente. Los niveles de arsénico y de plomo, no excedieron los límites máximos permisibles. El grupo de ciclofosfamida mostró una cantidad mayor de espermatozoides anormales (P<0,01) con respecto a los grupos de solución salina y NIMET; no se halló diferencia significativa entre los grupos de solución salina y NIMET. Conclusiones. El aceite de Plukenetia volubilis, es rico en ácidos grasos esenciales alfa-linolénico y linoleico, con una óptima proporción omega 6/omega 3, con significativas cantidades de tocoferoles y fitoesteroles los cuales le brindan una estabilidad oxidativa y con características físico-químicas que corroboran su calidad.

Published: June 2019

El artículo resalta la importancia que tiene la satisfacción laboral de los empleados para el rendimiento empresarial; y, cuales son las variables relacionadas con la satisfacción, para ello se ha considerado el criterio de varios autores que aportan con sus conocimientos y definiciones que permiten fundamentar la investigación y comprender el panorama. El objetivo fue conocer el nivel de satisfacción laboral de los empleados que trabajan en las microempresas productoras de derivados lácteos, determinar cómo se sienten dentro de su puesto de trabajo, los factores internos y externos que conllevan a la satisfacción o insatisfacción y cómo esto influye en la productividad de las microempresas. De acuerdo a los resultados obtenidos se concluye que no existe correlación entre estas dos variables y cada una es independiente de la otra. La satisfacción laboral depende de otras variables como: la relación que existe con los jefes directivos, la supervisión recibida, las condiciones de trabajo, el sistema de recompensas, la motivación, las políticas de la empresa, las oportunidades de desarrollo profesional, la oportunidad de innovar y tomar riesgos, entre otras. Por otro lado la productividad está medida como la cantidad de productos obtenidos a partir de la utilización de los recursos; es decir que la combinación óptima de los insumos, una buena definición de procesos productivos y el ajuste de tiempos pueden mejorar los resultados esperados e incrementar la productividad.

Published: June 2019

In this study, it was aimed to plate PdCu alloy layer
on porous glass supports by using electroless plating technique. It was also
aimed to achieve coexistence of fcc (face-centered cubic) and bcc
(body-centered cubic) phases on the alloy membrane layer. The fcc and bcc
phases were seen together in the structures of the membranes synthesized at all
three bath temperatures (30 °C, 40 °C and 50 °C), but, it was shown that the
most suitable coating rate was achieved when the coating bath temperature was
40 °C. The appropriate composition of PdCu (74% Pd, 26% Cu) was achieved by
following a synthesis procedure as follows: Coating in Pd bath three times for
60 minutes each followed by coating in Cu bath at the low formaldehyde
concentration (5 mL/L) for 15 minutes. Hydrogen flux in the membrane was
measured as 1.9x10-6 mol/cm2s. After flux measurements,
it was determined that the membrane structure changed and the fcc (200)
structure, which did not previously exist in the structure, was formed.
