the objective of this study was to evaluate the morphometric and reproductive traits of indigenous dairy goat types. it was conducted in three districts (ebnat, gonji-kolela and farta) based on the agro-ecological differences, goat population potentials and experience of the farmers using goat milk. semi-structured questionnaires, field observations, morphological and reproductive trait measure...

In matrix acidizing operations, the main goal is increasing permeability. For production engineers, it is desirable that acid could be injected into whole [M.N.1] [amehri.gh2] pay zone. Sometimes, this pay zone has a long height and various sub-layers which have different permeability values. To prevent acid from going completely into the most permeable sub-layer, one of the useful techniques i...

Control of Heating, Ventilating, and Air Conditioning (HVAC) aims to provide a comfortable environment for human life in terms temperature humidity improve indoor air quality. The HVAC system is multi-input multi-output, where the control design this challenging due its strong nonlinearity coupled influence both controllers on within thermal zone. aim study dual-controller system. first control...

The paper presents field demonstration results from the implementation of a model predictive control formulation to optimize the operation of a variable volume, dual-duct, multi-zone HVAC unit serving an existing mid-size commercial building. This full-scale study is used to estimate the benefits of advanced building control technologies that can be integrated during a retrofit. The predictive ...

A field experiment was conducted to evaluate the effect of planting pattern and irrigation system on antioxidant activity of wheat and Persian clover. The experiment was carried out as a two-factor factorial with three replications. The first factor was irrigation system (conventional and partial root-zone irrigation) and the second was planting pattern (sole wheat, sole Persian clover, alterna...

A Dual Parton Model with a formation zone intranuclear cascade in the spectators of the projectile and target nuclei is studied. The hadrons produced in the formation zone cascade contribute to Feynman–xF and lab–x distributions in the fragmentation regions of the target and projectile nuclei. We discuss the consequences of this model in the secondary cosmic ray production by analyzing the calc...

five-zone simulating moving bed (smb) system, designed for ternary separation, is a modified form of standard four-zone smb which is only effective in binary separation. it was reported in literature that the five-zone smb separates the extract-ii stream with a lower purity value than that of raffinate and extract-i streams. to address this issue, five zone smb was designed, using safety margin...
