Abstract: Grande parte dos métodos empregados na estimativa da altura de ondas,geradas pela a o do vento, necessita da determina o do comprimento da pista sobre a qual o vento atua. A escolha do método depende da natureza do corpo de água, podendo ser aplicável a áreas oceanicas ou a corpos d’água interiores, como baías, lagos e reservatórios.Uma das solu es rotineiras tem sido a aplica o direta do método validado em águas oceanicas para águas interiores sem levar, portanto, em considera o, o efeito de restri o oferecido pelas margens. N o obstante, a excessiva quantidade de opera es do métodoaplicado a corpos de água interiores (onde a margem é condi o de restri o), pode, se n o usado uma base gráfica suficientemente precisa da margem acrescido da subjetividade do operador, n o assegurar um grau de precis o satisfatório. Assim exposto, esta comunica o científica traz à luz esta discuss o, propondo uma solu o clássica baseada na aplica o do método adequado a águas interiores (Saville et al., 1954), via processamento automatizado.Para tanto, foi desenvolvido um programa em linguagem computacional AutoLISP. A aplica o do programa determinou as máximas pistas de vento no reservatório da barragem de Ilha Solteira, Estado de S o Paulo, como estando entre 9,5 e 12,5 km, contrariamente aum estudo anterior que havia previsto pistas bem superiores (fator da ordem de 3). Most methods employed to estimate the height of waves generatedby the wind require the surface length over which the wind blows. The choice of method depends on the nature of the water body, being applicable to ocean areas or interior water bodies, such as bays, lakes and reservoirs. One of the usual solutions has been the directusage of the method validated in ocean waters for interior waters, therefore, not taking into consideration the effect of the restriction imposed by the shores. Nevertheless, the excessivequantity of operations of the method applied to interior water bodies (where the shore is a restraint condition) may not assure a satisfactory precision degree, unless an accurate enough graphic base of the shore with the addition of the operator’s subjectivity is used.Thus, this scientific community brings this discussion to light, proposing a classic solution based on the application of the adequate method to interior waters (Saville et al., 1954), via automatized processing. Therefore, a program in AutoLISP, a computational language, has been developed. The application of the program has determined the maximum wind fetches in Ilha Solteira, state of S o Paulo, reservoir as being be

Abstract: this work focused on the hydrodynamic research aiming at the short-circuiting evaluation for five different outlet configurations through the compartments of a vertical paddle flocculation pilot unit. the tests were carried out with variable and constant velocity gradients, including alternative rotation direction of the paddles. the research pointed out that the relevance of outlet configuration increases with the reduction of the number of compartments. in opposite, the velocity gradient and the rotation direction of paddles seem less significant features. these results open the perspective of viable increasing of performance, with low financial investments, mainly for flocculation units with three or two compartments installed in overloaded water treatment plants.

Abstract: the efficiency of the concentric tubes internal-loop airlift reactor depends on the hydrodynamic conditions that affect oxygen transfer to the biofilm. this work studied the effects of the relation between diameters of the tubes and of the carrier (sand) concentration on the global oxygen transfer coefficient (kla). the tests - in 2,6 m high reactors with 250 mm external diameter and 100, 125, 150 and 200 mm internal diameters - were performed with air flow taxes up to 2,500 l.h-1 and sand concentrations up to 150 g.l-1. the kla increased slightly for 30 g.l-1 and decreased for higher concentrations, in accordance with related data for similar conditions. a model for kla in biphasic medium was fitted embracing all the external/internal area relationships tested, based on the reduction of the liquid phase transfer coefficient and the bubble diameter ratio with increasing air flow rates.

Abstract: The paper presents the results of a study research that aimed to analyze the participation and representation of women in politics in a Goiás period of nearly three decades. Thus, the study presents an updated picture of female representation in Goiás. The data analyzed in the survey have revealed that, in Goiás, women are still underrepresented in political and parliamentary arena. The research findings are very similar to the national and international scene. Therefore, the underrepresentation of women in parliament is not represented only a regional phenomenon, but worldwide.

Abstract: En esta investigación se estudió la eficiencia de remoción de nitrógeno total (NT) y nitrógeno amoniacal total (NAT) en aguas residuales de piscicultura intensiva y domésticas por medio de reactores aerobios de lecho fluidizado trifásicos con circulación en tubos concéntricos. Se utilizaron diferentes diámetros internos (100; 125 y 150mm) para un mismo diámetro externo de 250mm; se utilizó arena para filtros y carbón activado granular como medio soporte; los reactores se ensayaron con tiempos de retención hidráulica de 11.5 min para el reactor R100, y de tres horas para los R125 y R150. Las eficiencias medias de remoción del NT y del NAT fueron: en el R100 de 24% y 27%; en el R125 de 38% y 40%; y en el R150 de 30% y 49%, respectivamente. Cuanto mayor el diámetro interno mejor fue la eficiencia de remoción de NAT. This research was intended to study the efficiency of removing total nitrogen (TN) and total ammoniacal nitrogen (TAN) in waste water of intensive and domestic fish farming, through three-phase fluidized bed aerobic reactors with circulation in concentric tubes. Several internal diameters (100; 125; and 150 mm) were used for the same external diameter of 250 mm; filter sand and granular activated carbon were used as a support medium; reactors were tested with hydraulic retention times of 11.5 minutes for R100 reactor and three hours for R125 and R150 reactors. Mean removal efficiencies of TN and TAN were as follows: 24% for R100 Reactor; 38% and 40% for R125 Reactor; and 30% and 49% for R150 Reactor, respectively. The bigger the internal diameter the better the efficiency of TAN removal.

Abstract: Com o aumento da competitividade do setor produtivo, a pecuária leiteira brasileira busca, de todas as formas, sistemas de produ o que obtenham maior produtividade e menor custo. Entre as estratégias adotadas para tal fim, est o a melhoria da qualidade do rebanho e da forragem fornecida aos animais, de modo que estes expressem todo o seu potencial produtivo. A alfafa, conhecida pela excelente qualidade forrageira e boa palatabilidade, surge como boa op o. Entretanto, ainda há muito o que se trabalhar para a obten o de cultivares melhor adaptadas às condi es tropicais. Informa es teóricas sobre características de importancia forrageira s o necessárias para a orienta o dos programas de melhoramento. Nesse sentido, o objetivo deste trabalho foi estimar o coeficiente de repetibilidade para a produtividade de matéria seca de alfafa na regi o Sudeste do Brasil e determinar o número ideal de avalia es para a sele o dos genótipos superiores, por meio de quatro metodologias diferentes. Utilizaram-se dados de produtividade de matéria seca obtidos em quatro ensaios de compara o de cultivares de alfafa, conduzidos em diferentes regi es do Estado de Minas Gerais. Estimou-se o coeficiente de repetibilidade (r), para cada um dos ensaios, por meio dos métodos da análise de variancia (Anova), dos componentes principais com base na matriz de covariancia (CP-1) e de correla o (CP-2), e pela análise estrutural baseada na matriz de correla o. Observou-se que houve boa concordancia entre as diferentes metodologias de estima o do coeficiente de repetibilidade em todos os ensaios. A estimativa média de repetibilidade para produ o de matéria seca de alfafa nos quatro ensaios avaliados foi de 0,59, com coeficiente de determina o médio de 0,96. Constatou-se, também, que a realiza o de apenas quatro cortes, em média, foram suficientes para se conhecer o real valor genotípico das cultivares testadas, com 85% de confiabilidade.
Training Needs of International Medical Graduates [IMGs] in Psychiatry  [PDF]

Open Journal of Psychiatry (OJPsych) , 2014, DOI: 10.4236/ojpsych.2014.44036
Abstract: The potential shortage of psychiatrists over the next 5 - 10 years has focused attention on the need to recruit more IMGs to fill the needs rather than use nurse practitioners or physician assistants. IMGs make up about 1/3 of first year psychiatry residents. These individuals have been found to provide services to the poor, the elderly and the psychotic. The quality of their medical work has been found to be satisfactory. The training needs of these physicians require an understanding on the part of their teachers that they come from cultures with different values that we have. The extended families of these primarily Asian residents clash with our strong commitment to individualism. It leads to a We-self rather than our I-Self. This difference coupled with the stress of leaving to come to a new culture is a great stress. Their exposure to psychiatry has been limited. They request and need more interview demonstration and practice, ore feedback and examinations. They should have help in accent reduction. They should be exposed to the working of the hospital by sitting on departmental and hospital committees. The faculty should extend their social opportunities and work as mentors on joint projects. Courses on the history of American culture should be taught. Psychotherapy for them should be encouraged as well as teaching medical ethics. They must become the major educational concern for the department that they are in.
