Com o objetivo de estudar as características qualitativas da carcaça e da carne de bovinos machos não-castrados abatidos aos 13-14 meses de idade, foram utilizados 16 animais, oito Aberdeen Angus (AA) e oito Hereford (HE), alimentados na fase de terminação com dietas formuladas com dois níveis de energia digestível (ED), o menor 3,07 Mcal/kg de ED (12% de concentrado) e o maior 3,18 Mcal/kg de ED (32% de concentrado). Os animais foram confinados a partir dos 9 meses de idade com peso médio de 220,31 kg e foram abatidos quando, por estimativa, o peso da carcaça atingiu, no mínimo, 190 kg. O delineamento experimental foi o inteiramente casualizado, com quatro tratamentos, em esquema fatorial 2 x 2 (duas raças vs dois níveis de energia). A carne dos animais HE perdeu menos líquido durante os processos de descongelamento e cocção. Além disso, apresentou maior maciez pelo painel de avaliadores e pelo aparelho Shear Force. As carcaças dos animais que receberam o maior nível de energia na dieta apresentaram maior proporção de músculo e, durante o processo de descongelamento, perdeu menos líquido (2,54 vs 7,22%). Quando avaliada pelo aparelho Shear Force, a carne dos animais alimentados com maior nível de energia na dieta mostrou-se mais macia. Verificou-se interação significativa raça ´ nível de energia para o sabor e a coloração da carne, de modo que a carne dos animais AA, alimentados com menor nível de energia, mostrou-se mais saborosa e com melhor coloração.

The objective of this work was to compare the results of measuring the specific gravity (SG) of laying hen eggs by using a weighing apparatus and the saline flotation method (SFM). Two hundred eggs from two genetic lines were distributed randomly into two groups of 50 eggs per genetic line and were submitted to two different sequences of SG measurement. Not significant differences were found between the two methods. The weighing apparatus measured the SG of the eggs accurately as the SFM.

As arterial hypertension can be diagnosed by different methods, among which are the traditional auscultatory instrument and the automated oscillometric monitor, the aim of this study was to compare the performance of these instruments, to evaluate the reliability of the digital oscillometer. The sample consisted of 40 patients under dental treatment, whose blood pressure measurements were recorded. The measurements of systolic and diastolic blood pressures were evaluated in terms of their intraclass correlation coefficients (r). For systolic blood pressure, an excellent level of agreement was found between the instruments, with r=0.93, and for diastolic blood pressure, there was a good level of agreement (r=0.75). It was concluded, from the excellent agreement for systolic blood pressure, that the oscillometric monitor can be recommended for the monitoring of the variations of that pressure in the same individual, while the good agreement obtained in the determination of the diastolic blood pressure indicates that the oscillometric method is reliable. However, new studies need to be carried out for a better understanding of the disagreements that can occur in the diastolic pressure results.

The Irrigameter is aevapotranspiration measuring device used in irrigation management to optimize water. However, its use requires a prior adjustment to weather conditions where it will be used. The objective of this study was identify the corresponding height of water level inside the evaporimeterIrrigameter that estimate reference evapotranspiration in climate of the plateau of Vitoria da Conquista - BA, in different seasons. The experiment was a completely randomized design with five treatments and three replications. For each treatment was determined an average coefficient for the Irrigameter called K I, calculated as the ratio of estimated evapotranspiration in Irrigameter (ET I) and reference evapotranspiration (ET 0). The ET 0 was obtained by the Penman-Monteith - FAO 56. The results showed that the coefficients of Irrigameter increased exponentially with increasing water level inside the evaporimeter, and the equipment must be operated with the water level equal to 5.2 cm for better estimation of ET 0. The remaining heights observed in different seasons showed no significant difference when compared to annual average used as a reference in this study.
