A penalty finite element analysis with bi-quadratic elements is carried out to investigate the effects of uniform and non-uniform heating of inclined walls on natural convection flows within a isosceles triangular enclosure. Two cases of thermal boundary conditions are considered; case I: two inclined walls are uniformly heated while the bottom wall is cold isothermal and case II: two inclined ...
This study investigates the effect enclosure on some soil characteristics in two different climates; include semi-arid climate (Incheh boron region) and Cold climate of semi-humid (Chahar bagh) in Golestan province. In order to do soil sampling by the systematic-random methods, 5 transect were used in each areas and Physical and chemical properties were measure. T-test method was used in order ...
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...
The known area of distribution of kites is very large, from Arabia and the Near East, to Armenia in the Caucasus and the Aralo-Caspian region, namely south-western Kazakhstan and western Uzbekistan (e.g. Barge et al. 2013).although still there is not any official report about its existence in Iranian plateau but regards to the vast distribution of desert kites from Egypt in west to Kazakhstan i...
in this paper, some elementary operations on triangular fuzzynumbers (tfns) are defined. we also define some operations on triangularfuzzy matrices (tfms) such as trace and triangular fuzzy determinant(tfd). using elementary operations, some important properties of tfms arepresented. the concept of adjoints on tfm is discussed and some of theirproperties are. some special types of tfms (e.g. pu...
A numerical investigation was carried out in order to predict the effects of symmetric heating on irregular acoustic streaming in air-filled shallow enclosures. The fluid motion is driven by periodic vibration of the enclosure left wall. The vertical walls of the enclosure are adiabatic while the horizontal walls are heated symmetrically. A control-volume method based, explicit time-marching Fl...
