Abstract: two experiments were carried out to determine the nutritional requirement of calcium for broilers in growing (22 to 42 days), and finishing (43 to 53 days) phases. three hundred and sixty avian farm broiler chicks (180 from each sex) were used in both trails. the first experiment lasted 21 days and the second one, 10 days. a completely randomized design was used in both experiments, with six treatments, six replications and 10 birds per experimental unity (five males and five females). two basal diets were formulated to meet the birds nutritional requirements, except for the calcium, that remained deficient at the level of 0.16%. the basal diets in each experiment were supplemented with 0.0, 0.25, 0.50, 0.75, 1.00, and 1.25% calcium from calcium carbonate, resulting in the levels of 0.16, 0.41, 0.66, 0.91, 1.16 and 1.41% of calcium, and the treatments were used to estimated the calcium requirements of broilers. at the end of each experiment, 72 birds were sacrificed by cervical dislocation for the purpose of determining the tibia breaking strength and tibia obtained calcium and ash. weight gain, feed:gain ratio, tibia calcium contents (percentage and gram), tibia breaking strength (kgf), ashes contents in the tibia (percentage and gram) were the evaluated variables. the calcium requirements were estimated using the quadratic regression model. according to the biological values observed for the chickens were suggested the calcium requirements estimates of 1.02 and 1.01% for broilers from 22 to 42 and 43 to 53 days old, respectively. however, according to the tibia breaking strength, the calcium requirement suggested for broilers from 22 to 42 and 43 to 53 days old would be 1.28 and 1.18% respectively.

Abstract: Recentemente, alguns acadêmicos têm demonstrado que a tradu o química pode auxiliar o trabalho histórico. O objetivo deste trabalho é traduzir alguns experimentos alquímicos de Robert Boyle para a química contemporanea, particularmente, aqueles que envolvem a água régia. A maior parte desses experimentos tem rela o com o mecanicismo boyleano, com receitas de produ o de compostos e com a padroniza o de procedimentos químicos. Muitos deles envolvem descri es precisas de propriedades, tais como o ponto de fus o, a mudan a de gosto, a libera o de som e bolhas, a corros o etc., que podem ser usadas como ferramentas de rastreamento para uma tradu o à nota o química atual. Recently some scholars have demonstrated that chemical translation can assist with historical work. The goal of this paper is to translate some of Robert Boyle's alchemical experiments involving aqua regia to contemporary chemistry. Most of them are related to his mechanistic ideas and addresses to routes of productions and for standardization of chemical procedures. Several involve precise descriptions of properties, such as melting point, change of taste, hissing, corrosion, bubbles etc., which may be very useful as tools for chemical translation.

Abstract: Purpose: The adaptation of BPI-B into North/Northeast of Brazil. The purpose of this study was the translation and adaptation of the BPI to Portuguese language, as spoken in Brazil, aiming at its posterior usage to measure both intensity and interference of pain in cancer patients’ life. Methods: The BPI-B was developed from the original BPI, using back-translation and committee review. The Back Translation was compared to the original BPI, as a result, the North/Northeast Brazilian version proved to have the same goals, and is similar to other current versions, observing its psychometrics properties. The inventory presented a final sample of 475 patients, whose average age was 54.37 years old (DP = 14.56), most female (58.9%). One hundred ninety-six patients in elementary school took part. It had its objective to group multiple indicators that responded to validation, precision and parsimony criteria. The patients answered the BPI at the very moment they were diagnosed as cancer cases. All of them were above 18 years old and they were also undergoing treatment at Cancer Ambulatory in a Hospital in Ceará, Brazil. The retest was carried, after about a month of the first application. In order to verify the reliability of inventory adaptation, the exploratory factorial analysis was used as the oblique rotation axis. Results: Exploratory factor analysis confirmed two underlying dimensions, pain severity, and pain interference, with Cronbach’s α 0.833 and 0.733, respectively. Conclusion: A proposition of a north/northeast Brazilian version of BPI turned out to be adequate, gathering evidences of adaptation and internal consistency similar to already validated versions.

Abstract: phenotypic and antigenic variations among mycoplasma gallisepticum vaccine f and ts-11 strains were investigated by sds-page and serological methods (hemagglutination-inhibition and immunoblot assays). the sds-page system followed by densitometer analysis showed weak phenotypic variability between the strains, being the major difference close to the 75 kda level where a prominent peptide band was detected only in the f vaccine strain. polyclonal antibodies to the m. gallisepticum antigens produced in chickens were used in serological tests for this antigenic variability study. there were strong cross-reactions between the strains and homologous/ heterologous antibodies. the most evident characteristic was the specific response of the vaccine-type f polyclonal antiserum to the 75 kda peptide band of the homologous strain.

Abstract: Se conoce que, entre los 25 y 50 a os de edad, el cáncer es más frecuente en mujeres, fundamentalmente por los cánceres ginecológicos. Se decidió describir la situación actual del cáncer en la mujer cubana. Se calcularon las tasas promedio de incidencia y mortalidad (trienio 2000-2002) por 100 000 hab, estandarizadas a la población mundial para las 10 primeras localizaciones según sexo, y las específicas por edad y provincia de residencia. Se observó que las primeras localizaciones en mujeres, excluyendo piel, son: mama (mayor riesgo en occidente), cuello de útero (mayores riesgos en el oriente), pulmón y colon. Entre 20 y 39 a os de edad el cáncer más frecuente es el de cuello de útero y en los grupos restantes es el de mama. Se insistió en el papel de la prevención para reducir la magnitud del problema cáncer en la mujer. Las acciones deben concentrarse en disminuir el hábito de fumar, modificar estilos de vida e incrementar la participación en los programas de diagnóstico precoz. It is known that cancer, mainly the gynecological type, is more frequent in women aged 25-50 years, so it was decided to describe the current situation of cancer affecting the Cuban woman. Average incidence and mortality rates per 100 000 pop (2000-2002),standardized for the ten first locations by sex worldwide and specific by age and province of residence, were estimated. It was observed that the first locations in women, except for skin, were breast (highest incidence in the West), uterine neck (higher risks in the East), lung and colon. Uterine cancer is more common in 20-39 years age group whereas breast cancer predominates in the remaining groups. The role of prevention to reduce the extension of cancer in the female was stressed. Actions to be taken should be focused on reducing smoking, changing lifestyles and increasing the involvement of females in early diagnosis programs.
