Estudo em fadiga no aço API 5L X80 soldado pelo processo HF/ERW

The technological advancement in order to improve the methods of obtaining energy sources such as oil and natural gas is mainly motivated by the recent discovery of oil reserves. So, increasingly , there is a need for a thorough knowledge of the materials used in the manufacture of pipelines for transportation and exploration of oil and natural gas. The steels which follow the API standard (American Petroleum Institute), also known as high strenght low alloy (hsla), are used in the manufacture of these pipes, as they have, with their welded joints, mechanical properties to withstand the working conditions to which these ducts will be submitted . The objective of this study is to evaluate the fatigue behavior in microalloyed steel grade API 5L X80 welded by process HF / ERW . For this, axial fatigue tests to obtain S-N curve (stress vs. number of cycles ) were conducted. To complement the study, it was performed metallographic , fractographic , Vickers hardness tests and tensile tests to characterize the mechanical properties of the steel and check whether the values satisfy the specifications of the API 5L standard . From the fatigue tests , it was concluded that the surface finish influences directly on the fatigue life of the material

Determinação eletroanalítica e cromatográfica do corante solvente azul 14 em amostras de combustíveis

Métodos comparativos foram desenvolvidos para detectar e quantificar o corante solvente azul 14 (SA-14) em amostras de combustíveis. O método eletroanalítico foi baseado na técnica de voltametria de onda quadrada (VOQ) com detecção em +0,60 V vs. Ag/AgCl sobre o eletrodo de carbono vítreo, usando tampão Britton-Robinson e N, N-dimetilformamida (1:1, v/v) como eletrólito suporte. Para metodologia, envolvendo a cromatografia líquida de alta performance (CLAE) foi empregada uma fase móvel composta de acetonitrila e cloreto de lítio (85:15, v/v) e a detecção eletroquímica foi realizada em um potencial de oxidação em +0,65 V vs. Ag/AgCl. Sob as melhores condições de trabalho curvas de calibração foram obtidas, para ambos os métodos, as quais foram lineares na faixa de concentração de 5,0×10 -7 a 6,0×10 -6 mol L-1 (VOQ) e 8,0×10 -8 a 3,0×10 -6 mol L-1 (CLAE). Os métodos foram aplicados para quantificar o corante em amostras de álcool e querosene após um simples processo de extração em fase sólida com resultados de recuperação satisfatórios.

O pagamento por desempenho no contexto das reformas educacionais paulistas

This article presents the results of a research that has as its analysis focus the payment by performance, represented in the public educational system of the São Paulo State by the bonus-merit. The bonus, such as other measures implemented in the last decade, is part of neoliberal reforms that were predominant in the public educational system of the State. The article intends to debate the implications of this mechanism for the teaching from a bibliographic review about the topic as well as from the interpretation of data originated from a qualitative empirical investigation based on semi-structured interviews with second cycle teachers of high and middle schools of three regional departments of education. The results revealed an influence of performative and managerial elements in the organizational work of schools and teachers. Moreover, they showed that the payment by performance has not contributed for the improvement of the work conditions and for the career of the teachers, has a very limited impact to change the quality of education and thus represent a teacher accountability mechanism.

Burnout em dentistas do serviço público: ter ou não ter, eis a questão!

Objective: the objective of this study was to estimate the prevalence of Burnout Syndrome in dentists in the public service in the city of Araraquara – SP and its association with the variables of interest. Material and method: The sample was made up of the dentists active in the public health network (n = 60). Socio-demographic data was collected. The Oldenburg Burnout Inventory (OLBI) was used. Result: Of the participants, 60.0% were female and the average age was 41.9 ± 7.6 years. A large number of the professionals displayed a normal perception of the work conditions, premises, materials and equipment. 63.3% of the individuals feel tired even before arriving for work, 58.3% need more time to relax and to feel better, 70.0% are unable to deal well with the pressures of work, 50.0% feel they have no energy during or after work and 86.7% do not consider the work to be a positive challenge. It was observed that 48.3% of dentists displayed Burnout Syndrome, 11.7% Detachment and 13.3% Exhaustion. There was a significant association between the presence of Burnout and gender (p = 0.020) and the work premises (p = 0.011), with men being the most affected and those that considered the work premises very poor. Conclusion: It was concluded that the prevalence of Burnout Syndrome among dentists is high, with men and those who consider the work premises bad being the most affected.

Satisfação e o emprego no Sistema Público de Saúde na área de saúde bucal

The aim this study was to know work conditions of dental surgeon in Brazilian Health System (SUS), by their perception, analyzing: type of ingress, work regime, workload, realized income, existence of Career Plan, Posts and Ages (PCCS) and satisfaction with public employment. The sample was constituted by dental surgeons (n=83) of 12 cities public system from Health Regional Department XV – São José do Rio Preto City – São Paulo State. Data collection was by interviews using a questionnaire. Results point that 19% of interviewed people didn’t take an open competition to ingress on SUS. Statutory scheme of work was more adopted getting 57% of professionals. Different working days were observed: 57% is relative to 20 hours, 7% to 30 hours and 36 hours to 40 hours. About satisfaction with incomes, 66% of professionals were dissatisfied, observing the absence of PCCS in 11 cities. About satisfaction with public employment, just 5% said to be “dissatisfied”; 11% “few satisfied” and the majority 62% and 22% affirmed to be “satisfied” and “satisfied so much” respectively.

Família Enterobacteriaceae, Acinetobacter baumannii e Pseudomonados na microbiota bucal de pacientes mantidos em unidades de terapia intensiva

Enteric organisms, pseudomonads and other opportunistic microorganisms in the oral microbiota have been linked to serious infections in patients hospitalized in intensive care units (ICU). The present study evaluated the presence of family Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii in the mouth of patients in ICU, correlating it with oral and systemic conditions. Data on health, socioeconomic status, medication use, drug addiction, medical and family histories of patients held for more than 72 hours in the ICU with a diagnosis of severe infection or that developed this condition after entry in said unit were obtained. Fifty patients provided clinical samples of supragingival and subgingival biofilms, saliva and oral mucous membranes were collected, as well as respiratory secretions from patients with pneumonia, blood and urine for sepsis. The presence of target microorganisms was carried out by polymerase chain reaction (PCR) and by culture using selective media. The Chi-square and Mann-Whitney tests were used for statistical analysis, and the significance level was 5%. The intraoral clinical conditions of the patients were poor. The family Enterobacteriaceae was the most prevalent, affecting 39.5% of the supragingival biofilm samples of patients attended in ICU and 18.6% of patients in the control group, besides the rods were the only group found in extraoral samples.

Indústria frigorífica halal no Brasil, mão-de-obra islamita e estado de exceção

In the last decade, Brazilian meat export rates for Muslim religious countries have increased, and also has the immigration of Africans workers able to perform the slaughter following the precepts of Islam - religion that has expanded in the world, and thus, has the halal food segment. Halal, the Islamic ideology, means lawful, authorized by God: are those products that Allah in the Holy Qur'an releases for human consumption. To get halal certification some measures during slaughter/processing food should be taken. In the case of the slaughterhouses the animal must be slaughtered by a Muslim. Consequently, the demand for this skilled labor makes many African-Muslims get jobs in factories owned by BRF Foods, JBS and Marfrig; refugees and with their citizenship rights committed, these individuals live in a socio-political state of exception and overexploitation. In this study we intend to discuss the object of study Islamist workforce in Brazilian halal meat industry using the theoretical reflections of Giorgio Agamben (Homo Sacer in 2002, and State of Exception, 2004) and David Harvey (The Condition of Postmodernity, 2008, and The New Imperialism, 2004) to address the situation of immigrants in the meat business in Brazil, specially those on the halal certification segment, whose working and living conditions were described from academic studies and primary sources (articles in newspapers / magazines, websites, immigration official data). In addition we use the works of Rogério Heasbaert (O mito da desterritorialização, 2007) and Robert Kurz (Os paradoxos dos direitos humanos: inclusão e exclusão na modernidade, 2003) to discuss human mobility in this new century
