Horizontal convection in a rectangular enclosure driven by a linear temperature profile along the bottom boundary is investigated numerically using a high-resolution spectralelement discretization in space and a third-order time integration scheme for velocity and temperature fields. A Boussinesq approximation is employed to model buoyancy. The emphasis of this study is on the scaling of Nussel...

The morphogenesis of the C. elegans embryo is largely controlled by the development of the epidermis, also known as the hypodermis, a single epithelial layer that surrounds the animal. Morphogenesis of the epidermis involves cell-cell interactions with internal tissues, such as the developing nervous system and musculature. Genetic analysis of mutants with aberrant epidermal morphology has defi...

The adoption and adaptation of enclosures in the arid and semi-arid rangelands of sub-Saharan Africa is driven and sustained by a combination of factors. However, reviews indicate that these factors cannot be generalized, as they tend to be case specific. A study was therefore conducted to explore the history and reasons for enclosure establishment in Chepareria, a formerly degraded communal ra...

magnetohydrodynamic (mhd) mixed convection flow of cu–water nanofluid inside a two-sided lid-driven square enclosure with adiabatic horizontal walls and differentially heated sidewalls has been investigated numerically. the effects of moving lids direction, variations of richardson number, hartmann number, and volume fraction of nanoparticles on flow and temperature fields have been studied. th...

nowadays green house gases such as carbon have the most effect on global climate changes that can be decreased by plant and soil carbon sequestration of rangelands. livestock grazing has high potential to decrease or increase carbon storage. so this research investigated the effects of enclosure on plant carbon storage in rangeland of enclosure (shah tappeh-chah mahmood) and no enclosure (chiro...

Title of Document: SEPARATING THE EFFECTS OF GROUP SIZE, DENSITY, AND ENCLOSURE SIZE ON MOVEMENT AND USE OF SPACE IN DOMESTIC FOWL (Gallus gallus domesticus) Erin Hoerl Leone, Ph.D., 2008 Directed By: Professor Inmaculada Estevez, Department of Animal and Avian Science This project was designed to separate the confounded effects of group size, density, and enclosure size, and to examine the rol...

Abstract In many industrial contexts, buoyancy driven flows are the only cooling strategy in case of breakdown forced convection system. order to study those a simplified configuration, buoyancy-driven flow is generated inside cubic enclosure by partially heated block ( Ra = 1.4 × 10 9 ). The studied experimentally vertical median plane, part where i.e. close side block. Velocity fields, mean p...
