Process for producing biodiesel fuel with reduced viscosity and a cloud point below thirty-two (32) degrees fahrenheit

Triglycerides are reacted in a liquid phase reaction with methanol and a homogeneous basic catalyst. The reaction yields a spatially separated two phase result with an upper located non-polar phase consisting principally of non-polar methyl esters and a lower located phase consisting principally of glycerol and residual methyl esters. The glycerol phase is passed through a strong cationic ion exchanger to remove anions, resulting in a neutral product which is flashed to remove methanol and which is reacted with isobutylene in the presence of a strong acid catalyst to produce glycerol ethers. The glycerol ethers are then added back to the upper located methyl ethyl ester phase to provide an improved biodiesel fuel.

New historical archeointensity data from Brazil: Evidence for a large regional non-dipole field contribution over the past few centuries

We report new archeointensity data obtained from the analyses of baked clay elements (architectural and kiln brick fragments) sampled in Southeast Brazil and historically and/or archeologically dated between the end of the XVIth century and the beginning of the XXth century AD. The results were determined using the classical Thellier and Thellier protocol as modified by Coe, including partial thermoremanent magnetization (pTRM) and pTRM-tail checks, and the Triaxe protocol, which involves continuous high-temperature magnetization measurements. In both protocols, TRM anisotropy and cooling rate TRM dependence effects were taken into account for intensity determinations which were successfully performed for 150 specimens from 43 fragments, with a good agreement between intensity results obtained from the two procedures. Nine site-mean intensity values were derived from three to eight fragments and defined with standard deviations of less than 8%. The site-mean values vary from similar to 25 mu T to similar to 42 mu T and describe in Southeast Brazil a continuous decreasing trend by similar to 5 mu T per century between similar to 1600 AD and similar to 1900 AD. Their comparison with recent archeointensity results obtained from Northeast Brazil and reduced at a same latitude shows that: (1) the geocentric axial dipole approximation is not valid between these southeastern and northeastern regions of Brazil, whose latitudes differ by similar to 10 degrees, and (2) the available global geomagnetic field models (gufm1 models, their recalibrated versions and the CALSK3 models) are not sufficiently precise to reliably reproduce the non-dipole field effects which prevailed in Brazil for at least the 1600-1750 period. The large non-dipole contribution thus highlighted is most probably linked to the evolution of the South Atlantic Magnetic Anomaly (SAMA) during that period. Furthermore, although our dataset is limited, the Brazilian archeointensity data appear to support the view of a rather oscillatory behavior of the axial dipole moment during the past three centuries that would have been marked in particular by a moderate increase between the end of the XVIIIth century and the middle of the XIXth century followed by the well-known decrease from 1840 AD attested by direct measurements.

Chronic Autoimmune Thyroiditis in Industrial Areas in Brazil: A 15-Year Survey

To investigate whether there is an increased incidence of chronic autoimmune thyroiditis (CAT) in individuals living in the vicinity of industrial plants that manufacture petroleum byproducts in the state of So Paulo, Brazil. Between 1989 and 2004, 6,306 patients of both sexes, from 5 to 78 years old were divided in two groups according to their home location: Group 1: 3,356 residents living near industrial plants that manufacture petroleum byproducts (Region A), and Group 2: 2,950 residents living far from Region A in an area with predominantly steel industries (Region B). For all patients, we measured the serum levels of antithyroglobulin antibody, antithyroperoxidase antibody, triiodothyronine, thyroxine, free thyroxine and thyrostimulating hormone. Sonographic scans of the thyroid gland were also conducted. The proportion of patients with CAT coming from Region A increased from 2.5 % (5 patients with CAT/200 total patients) in 1992 to 57.6 % (106 patients with CAT/184 total patients) in 2001. This striking increase was highly significant (p < 0.001). Similar findings were not observed in Region B. The difference in the number of patients with CAT between 1989 and 2004 coming from Region A and Region B was highly significant (p < 0.001), with 905 CAT patients (83.95 %) in Region A and 173 CAT patients (16.05 %) in Region B. Our results showed a striking increase in the incidence of CAT in residents in the vicinity of large industrial plants that manufacture petroleum byproducts compared with residents living near steel industries, which opens the field to new areas of research.

Implantação da Norma Regulamentadora 32 e o controle dos acidentes de trabalho

OBJETIVO: Identificar os acidentes de trabalho com exposição à material biológico ocorridos em um hospital universitário, discutindo os resultados com o processo de implementação das medidas de segurança e saúde dos trabalhadores, exigidas pela Norma Regulamentadora NR-32. MÉTODOS: Estudo exploratório de abordagem quantitativa dos dados. Foram realizados levantamento dos acidentes de trabalho, as entrevistas com o coordenador do Serviço de Segurança e Medicina do Trabalho e a análise de dados documentais do Programa de Prevenção de Riscos Ambientais e do Programa de Controle Médico de Saúde Ocupacional. RESULTADOS: O percentual de acidentes de trabalho reduziu ao longo do período, no qual várias exigências dessa norma foram sendo adotadas. Acidentes com material perfurocortante foram os mais frequentes, não havendo em todos os setores do hospital o oferecimento dos dispositivos de segurança exigidos pela NR-32. CONCLUSÃO: Houve redução de acidentes de trabalho com material biológico no hospital estudado entre 2007 e 2009. Contudo, não é quantitativamente significativa, apesar da implantação de várias diretrizes da NR-32 ao longo dos anos. É necessária a colaboração entre gestores, serviços de segurança e trabalhadores na promoção da saúde no trabalho.

Informações para a elaboração de um manual educativo destinado às mulheres com câncer de mama

O objetivo deste estudo foi identificar as informações necessárias para a elaboração de um manual educativo, para auxiliar a mulher no pré-operatório para tratamento do câncer de mama. Para isso, foram entrevistadas mulheres com o diagnóstico de câncer de mama e submetidas ao procedimento cirúrgico pela primeira vez no máximo há seis meses. Foram incluídas 51 mulheres na faixa etária de 25 a 84 anos; 32 tinham companheiro; 26, ensino fundamental incompleto; 24 consideraram sua ocupação como "do lar"; 43,1% foram submetidas à mastectomia; e 82,4% realizaram linfadenectomia axilar. Responderam um instrumento com dados sócio-demográficos e perguntas relativas às informações/orientações recebidas da equipe de saúde sobre tipos de cirurgia, internação, anestesia, uso do dreno e intercorrências. Para a elaboração de material educativo, conhecer esta realidade e as expectativas dos sujeitos é indispensável para que sejam priorizadas as necessidades dos clientes, e não somente as exigências terapêuticas.

Two-Phase Frictional Pressure Drop and Flow Boiling Heat Transfer for R245fa in a 2.32-mm Tube

Experimental two-phase frictional pressure drop and flow boiling heat transfer results are presented for a horizontal 2.32-mm ID stainless-steel tube using R245fa as working fluid. The frictional pressure drop data was obtained under adiabatic and diabatic conditions. Experiments were performed for mass velocities ranging from 100 to 700 kg m−2 s−1 , heat flux from 0 to 55 kW m−2 , exit saturation temperatures of 31 and 41◦C, and vapor qualities from 0.10 to 0.99. Pressures drop gradients and heat transfer coefficients ranging from 1 to 70 kPa m−1 and from 1 to 7 kW m−2 K−1 were measured. It was found that the heat transfer coefficient is a strong function of the heat flux, mass velocity, and vapor quality. Five frictional pressure drop predictive methods were compared against the experimental database. The Cioncolini et al. (2009) method was found to work the best. Six flow boiling heat transfer predictive methods were also compared against the present database. Liu and Winterton (1991), Zhang et al. (2004), and Saitoh et al. (2007) were ranked as the best methods. They predicted the experimental flow boiling heat transfer data with an average error around 19%.
