Gallbladder Hydrops Associated with an Episode of Acute Liver Toxicity in the Adult: May It Be Considered a Surgical Emergency or Not?
Authors: Albu Sorin , Voidăzan Septimiu , Popa Dragoș
Published: August 2016

Introduction: Gallbladder hydrops is an increase in the volume of the gallbladder without any inflammatory sign, bacterial infection or the presence of any abnormalities of the biliary ducts or of the gallbladder.

Case presentation: A 52-year-old man presented at the Department of Internal Medicine complaining of moderate intensity pain in the right upper quadrant, low fever, fatigue, general weakness, symptoms stemming from an excessive intake of food (a meal abundant in animal proteins, fats, and alcohol) which appeared following a 6-week period of food restriction. On examination, the patient presented a globular abdomen, sensitive to deep palpation in the right upper quadrant, the liver and spleen being impalpable. Blood tests performed on admission showed liver-specific pathological changes. Abdominal ultrasound revealed hepatomegaly with homogeneous echostructure, slightly increased echogenicity with rear attenuation, with no focal images, intrahepatic biliary duct dilatation, or dilated suprahepatic veins. The gallbladder looked dropsical, with slender walls, with images of hyperechoic infundibular calculi with a posterior shadow cone, the largest having 14 mm. The portal vein and bile duct were normal in appearance.

Conclusions: Gallbladder hydrops is a disorder commonly seen in children. Its occurrence in adults is uncommon, moreover since it occurs simultaneously with an episode of acute toxic hepatitis. Surgery for this patient was possible only after normalization of liver function tests, on admission there being no subjective complaints of marked intensity that required immediate surgery.

Published: August 2016

With the implementation of sustainable management, libraries move towards sustainability and are converted into green libraries. The present study aimed to propose a model for sustainable management in Iranian libraries. This research was a qualitative and applied study. In order to obtain the required data and information, deep and semi-structured interviews with twelve experts in the fields of information and knowledge science and sustainable development were used. The interviewees were selected by a purposeful sampling method. For data analysis using grounded theory methodology, the topics raised by interviewees were coded and categorized in three steps. Fifty-five concepts from the coding stage were classified into six subcategories. In the final paradigm of sustainable management, these subcategories were classified into context, intervening and causal conditions, strategies, and consequences, which act in relation to the main category of sustainable management in order to establish a green library.
Sugar in disguise or healthy indulgence: A cross-cultural comparision of the perceptions of dietary vice/virtue bundles
Authors: Jiraporn Napatsorn , Charinsarn Alisara Rungnontarat , Sheridan Michael
Published: August 2016

Consumers often choose virtue food to attain health goals and vice food to achieve indulgence goals. However, food and beverage companies have begun to nullify the vice and virtue categories by bundling vice and virtue ingredients into a single item (e.g. Yogurt with Oreo topping). This research contrasts how consumers from Asian and Western cultures evaluate such vice/virtue food bundles. Building on the perceptual processes and regulatory focus literatures, two cross-cultural experiments using participants in Thailand and the U.S. shows that Westerners prefer virtue-heavy bundles to vice-heavy bundles while Asians show similar preference across both types of bundle. Process measures revealed that Asians perceive greater fit between vice and virtue components in the bundles than Westerners and this perceived fit mediates the effect of culture on their food choice. Study 2 reveals the boundary condition. Specifically, when regulatory focus was manipulated, the effect of culture is no longer significant. The findings provide managerial implications for food and beverage companies as well as contributions to consumer behavior literature.
Motivational effects of pay dispersion in pay for performance programs implemented in Romanian companies
Authors: Urieşi Sebastian
Published: August 2016

The present study investigates the motivational effects in a sample of Romanian employees in private companies that implement pay for performance programs of one of the characteristics of these programs, namely pay dispersion, and on the potential mediating role of organizational justice in these effects. To this aim, we examined the relationships between the amounts of pay dispersion introduced by the respective financial incentive system, employee perceptions of distributive and procedural justice, work motivation, and base salary, respectively. The results of the data analysis, performed through structural equation modeling, support our hypotheses concerning the positive effect of performance – related pay dispersion on motivation and the mediating role of the two dimensions of organizational justice in this effect. Larger financial rewards allocated by the financial incentive system for high performers increase employee perceptions of distributive and procedural justice, which, in turn, foster work motivation. Base salary was also found to influence pay dispersion, as well as perceived distributive justice.

Authors: Koh Kelly Sze Wee , Chan Leslie Soon-Lim , Ho Samuel K. M.
Published: August 2016

In Singapore, service sectors are dominated by SMEs. This study set out to investigate customer satisfaction as a critical factor in SME survival and indeed in helping to maintain the overall health of the economy. In this study, data were collected from a Singaporean SME which supplies and installs glass for construction projects. Departments involved were Sales & Marketing, Administration, and Installation. A questionnaire survey was administered to every customer of the company in 2013 in order to evaluate the services provided by the three departments. Customers were categorized into five groups: main contractors, designers/sub-contractors, property managers, home owners and commercial owners. Data were analyzed in terms of thirteen customer service variables identified from the literature. Statistical methods were applied to data analysis and findings were arrived at. Findings were found to be sufficiently significant to permit the formulation of a Total Customer Service Excellence Model for SMEs in Singapore.
Perceived unfairness in teacher-student conflict situations: students’ point of view
Authors: Čiuladienė Gražina , Račelytė Daiva
Published: August 2016

Student perceptions of injustice in the classroom can evoke destructive behavior, resistance, deception, aggression, and conflict escalation. Our study explores student experiences of unjust teacher behavior in educational settings. Students (N=99) were asked to remember a conflict they experienced during their studies. The conflict descriptions (N=78) were analysed and grouped according the type of perceived injustice (distributive, procedural, interactional) and 22 issues of unfair behaviour (Mikula et al., 1990). Our study revealed that perceived unfair grading, power demonstrations, and accusation were the most important predictors of teacher-student conflicts. Moreover students reported they experienced interactional injustice more frequently than they experienced distributive or procedural injustice.
Psychological aspects of sibling relational conflict vs. mental wellbeing levels in women’s perceptions
Authors: Walęcka-Matyja Katarzyna
Published: August 2016

My research aim was to analyse sibling relational conflicts perceived by adult sisters and selected conflict determinants. The study also considered the discriminating significance of the sibling relational conflict intensity for experiencing mental wellbeing. The study included 240 adult women, coming from the Łódź district (M=41.94 SD=15.71). The following research instruments were applied: Adult Sibling Relationship Questionnaire (ASRQ) by C. Stocker et al. (1997) in its – adapted form by K. Walęcka-Matyja (2014), and Mental Health Continuum-Short Form by C.L.M. Keyes (2008) as adapted by D. Karaś et al. (2014). The research results allowed us to conclude about ambivalent kinds of bonds between siblings in adulthood, clearly indicating variation in the relational conflicts depending on the examined sisters’ ages. However, the study did not confirm the significance of gender constellation for experiencing general wellbeing by the examined women. It did verify the hypothesis that there is a significant role for age-level psychological well-being.
Professional competences: Personality and Axiological Model (MOA) in verifying the sense of life quality
Authors: Mróz Barbara
Published: August 2016

It was assumed that the sense of the quality of life would reveal a significant relationship with personality-related and axiological dimensions among specialists (the Personality and Axiological Model MOA). It was hypothesized that there would be a positive correlation between independent personality-related variables for the sense of life quality (structure of personality: competence, relations, autonomy, adaptation and professional achievements). The determination coefficient was 0.47, that is, its variance was 47% of the variable sense of life quality being explained in the structural model MOA; by women 48%, by men 39%. In the discussion on the obtained results, emphasis should be put on the significance ascribed by specialists to the following dimensions: adaptation, competence and relations for the quality of life.
The Effect of Egg Yolk Oil on The Chemical, Physical and Sensory Properties of Mayonnaise
Authors: Kovalcuks Aleksandrs , Straumite Evita , Duma Māra
Published: August 2016

Egg yolk oil (EYO) is an essence of egg bioactive compounds. Extracted from egg yolk it can be used in various food products increasing their nutritional and biological value. Mayonnaise is a kind of a semi-solid oil-inwater emulsion containing 60-80% fat. Mayonnaise typically contains oil, egg yolk, vinegar, salt, sugar and thickening agents. Mayonnaise is the product where application of EYO can be evaluated. The aim of this study was to evaluate the effect of egg yolk oil on the chemical, physical and sensory properties of mayonnaise. EYO was added to mayonnaise in the concentrations of 1, 3, 5 and 7%. The main parameters of mayonnaise were determined using standard methods: lipid, protein, fatty acids, vitamin D, pH, viscosity, colour and acceptance of sensory properties (viscosity, egg aroma, egg taste, yellow colour, sour taste and creaminess). At analyzed concentrations EYO has no influence (p > 0.05) on mayonnaise pH, lipid and protein content, but an increase in EYO content decreases the viscosity of mayonnaise. Increasing amount of EYO additive resulted in more intensive yellow colour of mayonnaise. Additions of EYO enrich mayonnaise with vitamin D and docosahexaenoic acid. Sensory evaluation of mayonnaise samples showed panellists’ preference for mayonnaise with 3% and 5% EYO additive.

Authors: Dhaundiyal Alok , Singh Suraj B.
Published: August 2016

The main aim of this paper is to fuzzify the kinetic parameters, which have crisp nature, in order to obtain the realistic and accurate results. In the present study, the variance, upper limit of ‘dE’ and the frequency factor are assumed to be fuzzy numbers. The Gaussian distribution is considered as the distribution function, f (E), of Distributed Activation Energy Model (DAEM). The membership and the non-membership functions are evaluated by the trapezoidal fuzzy number. Thermo-analytical data has been found experimentally with the help of TGA/DTG analysis. The approximated solution of DAEM is obtained with the help of asymptotic expansion.

The calculations are performed in R, a programming language for statistical computing. An implementation in R is given.
To the Richest Go the Spoils? Immigration, Development, and the North-South Divide, 1970–2005
Authors: Sanderson Matthew R.
Published: August 2016

This paper empirically assesses, for the first time, the relationship between immigration and national economic development in both the global North and the global South. A series of panel models demonstrate that immigration exacerbates North-South inequalities through differential effects on average per capita incomes in the global North and global South. Immigration has positive effects on average incomes in both the North and the South, but the effect is larger in the global North. Thus the relationship between immigration and development evinces a Matthew Effect at the world level: by contributing to differential levels of economic development in the North and South, immigration widens international inequalities in the long term, resulting in the accumulation of advantage in the North. The implications of the results are discussed in the context theory and policy on the migration-development nexus.

Authors: Chong Lauren , Jamieson Nathan J. , Gill Deepak , Singh-Grewal Davinder , Craig Jonathan C. , Ju Angela , Hanson Camilla S. , Tong Allison
Published: August 2016

CONTEXT:

Epilepsy is a common and severe neurologic disease associated with increased mortality, seizure-related injury, and adverse psychological and quality-of-life outcomes.

OBJECTIVE:

To describe the perspectives of children and adolescents with epilepsy.

DATA SOURCES:

Medline, Embase, PsycINFO, and CINAHL from inception to August 2015.

STUDY SELECTION:

Qualitative studies on children’s experiences of epilepsy.

DATA EXTRACTION:

Results from primary studies. We used thematic synthesis to analyze the findings.

RESULTS:

Forty-three articles involving 951 participants aged 3 to 21 years across 21 countries were included. We identified 6 themes: loss of bodily control (being overtaken, susceptibility to physical harm, fragility of the brain, alertness to mortality, incapacitating fatigue), loss of privacy (declarative disease, humiliating involuntary function, unwanted special attention, social embarrassment of medicine-taking), inescapable inferiority and discrimination (vulnerability to prejudice, inability to achieve academically, consciousness of abnormality, parental shame, limiting social freedom), therapeutic burden and futility (unattainable closure, financial burden, overwhelming life disruption, exhaustion from trialing therapies, insurmountable side effects, awaiting a fabled remission), navigating health care (empowerment through information, valuing empathetic and responsive care, unexpected necessity of transition, fragmented and inconsistent care), and recontextualizing to regain normality (distinguishing disease from identity, taking ownership, gaining perspective and maturity, social and spiritual connectedness).

LIMITATIONS:

Non-English articles were excluded.

CONCLUSIONS:

Children with epilepsy experience vulnerability, disempowerment, and discrimination. Repeated treatment failure can raise doubt about the attainment of remission. Addressing stigma, future independence, and fear of death may improve the overall well-being of children with epilepsy.

ABSTRACT Mera, Santa Clara and Pastaza municipalities are located in the Ecuadorian Amazon region. The objective of the study was to identify plant species used in traditional medicine by small farmers of these localities, and to classify these plants according to locality, farmer ethnicity and purposes of use. It was also investigated whether the use of medicinal plants differs between the ethnic groups. Data were collected by applying a questionnaire and personal interview with 213 farmers belonging to two ethnicities (Kichwa and mestizo), and to different municipalities (Mera, Santa Clara and Pastaza). Generated data were analyzed using contingency tables and frequency and the most representative species were determined by proportion analysis comparison. A total of 34 families and 52 species of medicinal plants were identified. The most used species was Ilex guayusa which was cited 48 times. Santa Clara municipality and Kichwa farmers used the highest number of species. These species belonged to the Lamiaceae and Solanacease family, and the plants were used for treating stomach pain, cold and inflammations. There were significant differences (Chi square test p < 0.05) between localities and ethnicities (Kichwa and mestizo). There were differences in the use of medicinal plant species among members of the Kichwa ethnicity and mestizo farmers, depending on locality, being Ilex guayusa the most used species.

Published: August 2016

RESUMO: Diante das evidências de que os homens que fazem sexo com homens são afetados de forma desproporcional pelas infecções por HIV, investigamos os fatores de risco sociodemográficos, biológicos e de comportamentos sexuais associados à infecção por HIV, na cidade de Salvador, Bahia. Este trabalho é um recorte da pesquisa nacional "Comportamento, atitudes, práticas e prevalência de HIV e Sífilis entre homens que fazem sexo com homens em 10 cidades brasileiras", que foi do tipo corte transversal e selecionou participantes via técnica Respondent Driven Sampling . Devido à prevalência do HIV ser menor do que 10% e ao reduzido tamanho da amostra (383), utilizamos regressão logística exata nas análises para medir associação entre os fatores de risco e a infecção por HIV. A prevalência do HIV foi de 6,3% (IC95% 3,9 - 8,8), e após o ajuste do modelo final, os fatores de vulnerabilidade que se associaram à infecção por HIV foram: não fez teste de sífilis na vida (OR = 3,1: IC95% 1,3 - 7,3), ter mais de 8 parceiros sexuais (OR = 3,3; IC95% 1,4 - 8,1). Este estudo mostrou a alta prevalência do HIV na amostra, em comparação a população geral, bem como confirmou a importância da realização do teste de sífilis na vida no contexto da epidemia do HIV, sendo que essa detecção precoce permite uma aproximação das ações de prevenção para DST.

Published: August 2016

ABSTRACT: Objective: It was to identify trends of traumatic and non-traumatic causes of lower limb amputations, as well as the role played by population aging, traffic violence increase, public health policy of diabetes control program and drivers anti-alcohol laws on these amputations. Method: Hospitalization data recorded in the discharge forms of 32 hospitals located in the region of Ribeirão Preto, Brazil, from 1985 to 2008 were analyzed. Result: A total of 3,274 lower-limb amputations were analyzed, of which 95.2% were related to non-traumatic causes, mainly infectious and ischemic complications of diabetes mellitus. Cancer (2.8%) and congenital (1.3%) causes were included in this group. Only 4.8% were related to traumatic causes. Traumatic amputation average rate was 1.5 amputations in 100,000 habitants with a slight tendency of increase in the last 5 years. Non-traumatic causes showed an average rate of 30.0 amputations for 100,000 habitants and remained relatively constant during the whole period. Non-traumatic were much more predominant in patients older than 60 years and traumatic amputations occurred more frequently in patients younger than 39 years. Conclusion: The overall rates of amputation and the rates of traumatic and non-traumatic amputations remained nearly constant during the study period. The impact of diabetes control policies and the introduction of traffic safety laws could not be identified on the amputation rates.

RESUMO: Objetivo: Artigo metodológico com o objetivo de descrever a construção de um questionário de frequência alimentar (QFA) digital autoaplicado, desenvolvido para as coortes de nascimentos de Pelotas de 1982 e 1993. Métodos: O instrumento foi criado com base em QFAs anteriormente utilizados nas duas coortes em acompanhamentos nos anos de 2004 e 2008. O QFA foi elaborado incluindo 88 alimentos e/ou preparações cujas frequências foram agrupadas em categorias desde o valor mínimo de consumo de nunca ou < 1 vez/mês até o máximo de ≥ 5 vezes/dia. As opções fechadas relativas à porção foram construídas considerando recordatórios de 24 horas (R24Hs) anteriormente aplicados à subamostra da coorte de 1993. Três alternativas de porção foram construídas: igual, menos ou mais. A porção igual foi descrita com base no percentil 50 do consumo de cada alimento, obtido a partir das distribuições das porções constantes nos R24H. Fotos das porções relativas ao percentil 50 de cada alimento foram também incluídas ao formato do programa. Resultados: Esse QFA digital incluiu alimentos e preparações que atendem aos objetivos das pesquisas atuais. A aparência do programa foi atrativa à equipe de trabalho e também aos participantes do estudo. O tempo médio de aplicação de 12 minutos e a facilidade de preenchimento possibilitaram que vários participantes respondessem às questões ao mesmo tempo. Além disso, o instrumento dispensou a necessidade de entrevistador e a dupla entrada de dados em programa específico. Conclusão: Recomenda-se o uso dessa mesma estratégia em outros estudos, adaptando-a aos diferentes contextos e situações.
Da tragédia à comédia: uma leitura do conto "A cartomante", de Machado de Assis
Authors: PEREIRA EDER RODRIGUES
Published: August 2016

Resumo O presente artigo estabelece uma relação comparativista entre o conto "A cartomante", de Machado de Assis, e a tragédia Hamlet, de Shakespeare, utilizando para isso alguns conceitos da poética clássica, da teoria dos gêneros e da estilística. Com isso, observamos o modo como determinados elementos estruturais e temáticos existentes na peça de Shakespeare assumem uma nova dimensão no conto de Machado que, além de realizar um diálogo com a tragédia shakespeariana, reaviva diversas questões de ordem estética e ideológica.

Criatura e/ou Criador:transformações do Supremo Tribunal Federal sob a Constituição de 1988
Authors: Arguelhes Diego Werneck , Ribeiro Leandro Molhano
Published: August 2016

Resumo Atualmente, o Supremo Tribunal Federal (STF) ocupa hoje posição central no processo político nacional. Suas decisões são a última palavra oficial sobre os temas a que se referem, concentrando poderes para resolver conflitos políticos e morais, para além das esferas majoritárias. Esse cenário, porém, é muito diferente dos anos 1990, quando o STF não ocupava posição tão destacada na política brasileira. Neste artigo, discutiremos essa configuração do poder e do papel do STF por meio de análises do tribunal que a constituinte criou, mas também do que os ministros criaram por meio de práticas institucionais e interpretações de seus próprios poderes. Exploraremos algumas consequências mais recentes da manifestação do próprio poder conferido ao STF nesse processo de reconfiguração institucional, delineando, de maneira preliminar, novas tendências na forma de atuação política do tribunal. Argumentamos, também, que, em vez de atuar apenas como ponto de veto a decisões majoritárias, como câmara revisora do que faz o Congresso, o tribunal já sinalizou disposição para receber (e aceitar) provocações para funcionar como uma espécie de primeira câmara legislativa.
Combate às transferências bancárias ilegítimas pela Internet no direito português:entre as experiências domésticas e políticas globais concertadas
Authors: Correia Pedro Miguel Alves Ribeiro , Jesus Inês Oliveira Andrade de
Published: August 2016

Resumo O estudo que conduziu a este artigo atenta na forma como a lei e o direito português proporcionam mecanismos que permitem levar a cabo políticas de combate às transferências bancárias ilegítimas com recurso à Internet. A abordagem metodológica consistiu não apenas numa análise rigorosa do enquadramento jurídico da questão mas também numa análise estatística de dados correspondentes aos crimes de burla informática e nas comunicações registados pelas autoridades policiais. É apresentada argumentação a favor de que as transferências bancárias ilegítimas com recurso à Internet devam ser consideradas fraudes ao invés de burlas, e são apresentados dados que corroboram a ideia de que, nos próximos cinco a dez anos, este problema se tornará muitíssimo relevante para o sistema judiciário e para a sociedade como um todo. Finalmente, e como parte do esforço em prol de uma política internacional concertada, sugere-se que estudos futuros alarguem a investigação da temática apresentada a outras regiões geográficas, de que é exemplo a América do Sul e, em particular, a países com grande proximidade a Portugal, como é o caso do Brasil.

Authors: Westphalen Ana Paula Campos , Corção Gertrudes , Benetti Antônio Domingues
Published: August 2016

RESUMO: Este artigo de revisão aborda o uso do carvão ativado biológico no tratamento das águas para consumo humano. O tratamento biológico tem aplicação na redução da instabilidade da água potável causada por matéria orgânica biodegradável e compostos inorgânicos reduzidos presentes em baixas concentrações. A instabilidade tem efeitos prejudiciais à qualidade da água potável, tais como o crescimento de bactérias e a formação de biofilmes na rede de distribuição. O artigo discute as causas e consequências da instabilidade, as medidas de avaliação da matéria orgânica, os mecanismos de formação e controle de biofilmes no carvão ativado granular e as técnicas de avaliação microbiológica e da biodiversidade nos biofilmes. Além disso, analisa-se também a integração do carvão ativado biológico com outros processos usados no tratamento de água para consumo humano.

Authors: Pedrosa Ricardo Nobrega , Miranda Lívia Izabel Bezerra de , Ribeiro Márcia Maria Rios
Published: August 2016

RESUMO: Nos últimos dez anos, o município de Campina Grande, Paraíba, foi beneficiado com inúmeros programas de urbanização em áreas de interesse social. Com a publicação da Lei nº 11.445/2007 (Lei do Saneamento), dada a centralidade que o saneamento ambiental tem na vida das pessoas, é fundamental que processos de Avaliação Pós-Ocupação sejam procedidos. Esta pesquisa objetivou avaliar a infraestrutura de saneamento em área de interesse social sob diversos cenários de urbanização. O caso de estudo foi a comunidade Novo Horizonte, localizada na zona sul do município, por se tratar de uma área urbanizada com recursos do Orçamento Geral da União. Propõe-se uma metodologia para a aferição da salubridade ambiental, na qual é definido um Índice de Salubridade Ambiental para a comunidade Novo Horizonte, composto por sete indicadores relacionados com o saneamento ambiental, a saúde pública e aspectos socioeconômicos. Os resultados mostraram que a urbanização não ocorreu na amplitude desejada e que dentre os indicadores analisados houve destaque para o abastecimento de água e os resíduos sólidos, enquanto os relacionados aos aspectos socioeconômicos foram os que apresentaram os piores resultados dentre os cenários pesquisados. A pesquisa constatou quão nefasta é a execução de uma obra de urbanização segmentada no tempo, e realizada por empresas distintas, sobretudo quando os serviços de esgotamento sanitário são realizados em um primeiro instante. Conclui-se que a efetivação de avaliação pós-ocupacional é necessária para realimentar os projetos de urbanização em execução, ou a executar, quer seja com recursos públicos ou privados.

Published: August 2016

RESUMO: o objetivo do presente estudo foi analisar a experiência de irmãos de pessoas surdas acerca de sua história de vida e das implicações da deficiência nos relacionamentos fraternos. Tratou-se de um estudo exploratório, de abordagem qualitativa, que contou com a participação de cinco irmãos de pessoas surdas com idade entre 31 a 44 anos. Para a coleta de dados foram utilizados os seguintes instrumentos: questionário de identificação e roteiro de entrevista em profundidade. Os dados obtidos foram analisados a partir do modelo de produções de sentido das práticas discursivas. Os principais resultados apontaram que a dificuldade de comunicação entre os participantes e seus irmãos surdos repercutiu em questões nos relacionamentos desde a infância até a fase adulta. Considera-se que as questões inerentes à deficiência trouxeram consequências a todos os membros da família, em especial nos quesitos relacionamentos e comunicação e que disponibilizar atenção especializada aos pais e irmãos destas pessoas auxiliaria no manejo das situações vinculadas à deficiência e fortalecimento dos vínculos familiares.

The effect of intramuscular thiamine injection on the activity of trypsin-like enzymes in the liver, kidneys, stomach and small intestine of white rats has been researched. In the organs of intact rats, the maximum activity of trypsin-like proteases has been established in the small intestine, and the minimum one in the liver. Thiamine parenteral administration leads to the decrease of trypsin-like protease activity in the liver, kidney and stomach, and the increase of the enzyme activity in the small intestine that suggests the possibility of non-coenzyme thiamine effect on the trypsin-like enzyme activity.

The process of mixing in combined extruders is discussed in this paper. We propose a method for determining the quality of the composites. Strip thickness is a quality criterion. As a result of our research, programs have been established, which can determine the mixing quality of polymer compositions. The quality criterion in this method is the strip thickness. Objective was to create programs that allow specifying the desired compositions quality during their processing. Adequacy of the task solution has been verified by experimental studies in the test unit.

Role of Cardiac Troponin I level in predicting in-hospital outcomes in patients with ST-segment elevation myocardial infarction in Erbil-Iraq
Authors: Zangana Salam , Al-Othman Abdulkareem , Al-Tawil Namir
Published: August 2016

Background and objectives: The correlation of cardiac troponin I with early in-hospital outcomes in acute myocardial infarction is not well established. This study aims to assess the role of troponin I in predicting in-hospital outcomes and early left ventricular systolic dysfunction in patients with ST-segment elevation myocardial infarction (STEMI). Patients and methods: In a prospective study, 116 patients (74males and 42 females), with STEMI who had been admitted to the Coronary CareUnit from March 2015 to September 2015 were enrolled. Patients were divided according to the level of troponin I on admission into 3 groups (low, medium and high elevation). Results: The mean age (+ SD) of the patients was 60+11.4 years. The troponin level of 66.2% of males was high compared with 52.4% of females (p=0.002). The incidence of acute pulmonary edema (21.1%), cardiogenic shock (7%) and early left ventricular systolic dysfunction (49.3%) was significantly higher among patients with high troponin level compared with (0%, 0% and 16%, respectively) among patients with low troponin level. All deaths and cardiac arrest were of high troponin level. Conclusions: High admission troponin I in STEMI permits early identification of patients at increased risk of major cardiac complications and death.
Case Study of Soft Particle Fluid to Improve Proppant Transport and Placement

Published: August 2016

Optimization of conductive fracture area is perhaps the most critical tenets of fracture stimulation. Several attempts have been implemented to improve the effective fracture area, such as hybrid fracturing, ultra-lightweight proppant (ULWP) delivery, channel fracturing, and slug fracturing. The techniques are all based on viscosity-governed proppant transport mechanisms. This paper presents a new fluid system, based on packing of soft particles, for nearly perfect proppant suspension to improve proppant transport and vertical distribution in fractures.

Proppant particles are trapped in the "void" space created by particles packing against each other, and the mechanism is completely different from that of conventional fracturing fluids. It improves effective fracture height by placing proppant across the complete productive interval under downhole conditions when properly applied. This leads to better transverse and vertical placement of proppant in the fracture and significantly increases the fractured surface area.

The fluid was tested extensively in conventional fracturing fluid protocols to confirm its feasibility because, mechanistically, it works completely different from conventional fluids. Hydration tests show that the hydration rate can be tuned to maintain the particle integrity during fracturing treatment. HPHT rheology tests show that the fluid is compatible with conventional fluid additives. Static proppant settling tests show superior proppant suspension capabilities. The fluid can be decomposed with live and encapsulated oxidizer breakers to meet treatment design requirement. The fluid can be completely cleaned up and regained proppant pack conductivity was close to unity. Interesting fluid behavior was observed during large scale slot cell testing at room temperature. The fluid was successfully applied in the Cotton Valley and it was confirmed that the novel fluid can be smoothly pumped through fracturing equipment and it also offers several operational benefits.

Criteria and considerations for successful application of such fluids to optimize proppant placement and maximize fracture conductivity are discussed. Job design is elaborated in terms of fluid mechanics and proppant transportation mechanics differences and benefits over traditional crosslinked gel systems. The execution, experiences, and subsequent well performance of treatment applications results are compared to offsets treated with a traditional crosslinked gel system.

Published: August 2016

For tight oil horizontal completion, optimization of reservoir modeling and fracture design relies highly on correct understanding of the relationship between production and reservoir characteristics. Due to reservoir heterogeneous properties, it is also challenging to understand the relevant correspondence between the production and petrophysical and petromechanical stage characteristics. Understanding stage contributions during initial and short to medium term production is the first and important step to reveal such a relationship.

This article describes an effort in using chemical tracers to evaluate initial oil and water productions in a horizontal multi-stage fracture well. Determining an exact contribution per stage of oil and water in initial production is achieved here for the first time. This quantitative understanding of how each stage has contributed to the comingle production in initial production provides increased understanding of the correlation between stage production and reservoir characteristics.

The deep, tight gas reservoir in the Daqing oil field, P. R. China has multiple parallel sandy conglomerates with horizontal heterogeneity and poor historical production from vertical wells and single-lateral horizontal wells. These blocks comprise a large volcanic gas reservoir, which is also challenging for directional drilling. This paper describes a dual-lateral completion with hydraulic fracturing that addresses these production issues.

To deploy a stacked dual-lateral well in this reservoir, the deep well depth and its high temperature are considered. The junction must be sealed because of the borehole stability and gas. Re-entry to both laterals, temporarily isolation of laterals, openhole multi-stage hydraulic fracturing and commingled production was possible with a multilateral completion system. This was the operator's first installation of this technology.

As a result of comprehensive study, the TAML Level 4 Hook Hanger Multilateral System and One-trip Open Hole Multi-stage Frac System were selected. The junction was successfully cemented after installation of the Hook Hanger System. Each lateral was installed with more than 10 stages of frac system completion tools. After both laterals were hydraulically frac and flow tested, the commingled upper completion string was installed for commercial production.

The application of multilateral technology in this field was completed safely. Gas production rates from the multilateral well tested 4.3 times greater than the average production rate from the three offset vertical wells. The absolute open flow rate achieved was more than 1MMSCM, which is the biggest producer for tight gas reservoir in Daqing area. This production rate indicated that the dual-lateral well fracture completion method was applicable for this reservoir.
