Productive performance of simmental dairy cows supplemented with ricinoleic acid from castor oil

The aim of this study was to evaluate the performance and blood parameters of Simmental dairy cows, supplemented with 2 g/day of ricinoleic acid (RA) in diet. Forty Simmental dairy cows in mid lactation, individually housed in stable type tie-stall, were used. The animals were randomly assigned to two treatments: 0 or 2 g of RA/animal/day. The experimental period consisted of 42 days divided into two 21-day. It was observed reduction in dry matter intake (DMI), increased milk, fat and FCM (fat corrected milk) yield, as well as increased of fat content of milk in cows that received RA in diets. No effects were observed for red and white blood cells and blood metabolites. Supplementation of RA improves performance of dairy cows in mid lactation.

Cardiac angiosarcoma: an unexpected diagnosis

Cardiac angiosarcoma is a rare entity. The incidence through autopsy findings ranges between 0.001% and 0.03%. The disease usually presents with non-specific symptoms, although asymptomatic cases are frequent; therefore, diagnosis is unexpected and consequently delayed. The authors report the case of a middle-aged man with a recent onset cough and dyspnea. He sought medical care several times without receiving a definite diagnosis until a plain chest radiography was taken showing a mediastinal enlargement, which was the reason why he was hospitalized for clinical investigation. During the diagnostic workup, an echodopplercardiogram and a thoracic computed tomography were performed, showing a heterogeneous soft-tissue mass infiltrating the pericardium and the anterior atrial wall. Multiple and scattered pulmonary nodules were also present. A pulmonary nodule was biopsied, which revealed an angiosarcoma. The clinical features added to the radiological and histological findings permitted the diagnosis of right atrial angiosarcoma. The authors highlight the unexpected pattern in the presentation of cardiac tumors.

Construction and performance of a simplified tension table for the determination of soil physicohydric attributes

For determining the soil attributes of water retention up to –10 kPa, including macroporosity and microporosity, the sand tension table has been proposed as a low-cost and high-performance alternative to Buchner funnels. This study demonstrates procedures for the installation, calibration and validation of a tension table built with inexpensive, easily purchased materials. We collected 14 oxisol samples with preserved structure to evaluate the efficiency of the constructed tension table as compared to Buchner funnels for determining the water content at potentials of –2, –4 and –6 kPa. No significant differences were observed for the porosity obtained using the tension table compared to that observed using the suction unit. RESUMO: Para determinacao dos atributos de retencao de agua no solo ate o potencial matricial de –10 kPa, como a macroporosidade e a microporosidade, tem sido sugerido o uso da mesa de tensao de areia, que se apresenta como uma alternativa de baixo custo e, sobretudo, de alto rendimento de trabalho em relacao aos Funis de Buchner. O objetivo deste trabalho foi demonstrar os procedimentos para montagem, calibracao e validacao de uma mesa de tensao construida com materiais de baixo custo e facil aquisicao. Foram coletadas 14 amostras indeformadas de um Latossolo Vermelho, para avaliar a eficiencia da mesa de tensao construida em relacao aos Funis de Buchner, na determinacao dos conteudos de agua nos potenciais de –2, –4 e –6 kPa. Nao foram encontradas diferencas significativas para porosidade, obtida na mesa de tensao, quando comparada a unidade de succao.

La backpack como símbolo: El caso de la Facultad de Idiomas de la UABJO, México

En este trabajo se explora el valor simbólico de la backpack (mochila que se porta en la espalda), con base en un estudio de caso. El trabajo de campo se realizó en la Facultad de Idiomas de la Universidad Estatal de Oaxaca (UABJO), México, durante el periodo comprendido entre febrero y junio del 2013. Mediante la observación minuciosa de los usos que un grupo determinado de estudiantes dan a este objeto, se pretende desentrañar sus posibles significados más allá de la función normativa de portar las pertenencias.
