In this research, the second Law for free convection of air flow in L-shaped enclosure with a heat generating body, is numerically studied. In this study, the continuity, momentum and energy equations are solved, using a finite volume method and SIMPLER algorithm. By positioning the heat generating body at three different locations inside the enclosure for three aspect ratios of enclosure in va...
While there has been some research on the parliamentary enclosure of upland waste in England and Wales during the eighteenth and nineteenth centuries, this topic still receives little attention in some recent accounts of parliamentary enclosure. Many aspects of the processes involved, and their impact on the landscape, are also poorly understood. Much research has proceeded either at a very gen...
A validated CFD by ANSYS model is built for a melting process of PCM (gallium), inside rectangular enclosure heated from one side and cooled another. This was carried out enabling the solidification in addition energy ANSYS. Regression front results utilized integrated numerical approach MATLAB to generate constants Nusselt correlations effective conductivity during different stages that can be...
The effect of enclosure design on diurnal activity and stereotypic behaviour was assessed in 17 adult Malayan Sun bears (Helarctos malayanus), kept either in barren indoor enclosures or relatively enriched outdoor enclosures. Locomotion was the most frequent activity observed in the indoor bears, followed by resting. In contrast, conspecifics housed outdoors spent most of the time resting. Elev...
Pigeons (Columba livia) searched for food hidden in the center of a square enclosure. On occasional tests without food, the enclosure was (a) unchanged from training (control tests), (b) moved to different corners of the testing room (corner tests), or (c) doubled in size (expansion tests). The birds showed localized search in the center of the enclosure on control and corner tests. On expansio...
The National Zoological Gardens of South Africa (NZG) is involved in the ex situ conservation of Gyps coprotheres, the Cape Griffon vulture (CGV) and houses 24 birds in a 100-yr-old aviary. Following the death of one vulture with high liver lead concentrations, an investigation was launched to ascertain the source(s) and consequences of lead toxicity in this breeding colony. Whole blood from 24...
Any improvement in agricultural systems that results in higher production should also reduce negative environmental impacts and enhance sustainability. The aim of this research was to investigate the effect of two different production systems, one open-field and the other shade-enclosure with four bocashi doses, in order to find the best environmental option in terms of yield, physiological and...
Measurements of the temperature distribution were performed in the upper (cold) boundary layer of a rectangular Rayleigh-Bénard cell with aspect ratios Gamma(x) = 5 and Gamma(y) = 1 using air with Prandtl number Pr = 0.71 as the working fluid. The range of investigated Rayleigh numbers was from Ra approximately 6 x 10(7) to Ra approximately 6 x 10(8), and the measurements were taken at two diff...
