A mathematical model has been formulated to predict the influence of high outdoor air temperature on the performance of small scale air - conditioning system using R22 and alternative refrigerants R290, R407C, R410A. All refrigerants were investigated in the cooling mode operation. The mathematical model results have been validated with experimental data extracted from split type air conditioner of 2 TR capacity. This entailed the construction of an experimental test rig which consists of four main parts. They are, the refrigeration system, psychrometric test facility, measuring instrumentation, and auxiliary systems. The conditioned air was maintained at 25 0C dry bulb and 19 0C wet bulb for all tests. The outdoor ambient air temperatur

In the petroleum industry, multiphase flow dynamics within the tubing string have gained significant attention due to associated challenges. Accurately predicting pressure drops and wellbore pressures is crucial for the effective modeling of vertical lift performance (VLP). This study focuses on predicting the multiphase flow behavior in four wells located in the Faihaa oil field in southern Iraq, utilizing PIPESIM software. The process of selecting the most appropriate multiphase correlation was performed by utilizing production test data to construct a comprehensive survey data catalog. Subsequently, the results were compared with the correlations available within the PIPESIM software. The outcomes reveal that the Hagedorn and Brown (H

This study was conducted during the two growing seasons 2016 and 2017 in the lath house at the College of Agriculture, Duhok University, Kurdistan Region of Iraq. Uniform and healthy transplants of (2) years old sweet cherry (Prunus avium L.) cultivars (evey loly and shampion) were used. The effects of three levels of Ammonium sulfate (NH₄)₂SO₄) (as source of nitrogen) (0, 3 and 6 gm L^-1), three levels of seaweed extracts (alga21st) concentrations (0, 1 and 2 gm.L^-1) and their interactions on leaf nutrients status, the content of protein, carbohydrate were investigated. The results showed that cv. evey loly transplants significantly

The one-dimensional, cylindrical coordinate, non-linear partial differential equation of transient heat conduction through a hollow cylindrical thermal insulation material of a thermal conductivity temperature dependent property proposed by an available empirical
function is solved analytically using Kirchhoff’s transformation. It is assumed that this insulating material is initially at a uniform temperature. Then, it is suddenly subjected at its inner radius with a step change in temperature. Four thermal insulation materials were selected. An identical analytical solution was achieved when comparing the results of temperature distribution with available analytical solution for the same four case studies that assume a constant the

يُعد التكافل الاجتماعي من المبادئ الأساسية التي يقوم عليها البناء الأخلاقي والاجتماعي في الإسلام، وهو يشمل جوانب متعددة من التعاون والتراحم بين أفراد المجتمع، والتي تؤثر بشكل مباشر على مكوناته وفي مقدمتها الأسرة المسلمة التي تُمثل حجر الزاوية في بناء المجتمع. ولا يقتصر التكافل الاجتماعي في الإسلام على المنفعة المادية - وإن كانت ركنًا أساسيًا فيه - بل يشمل جميع احتياجات الأفراد والمجتمعات، سواءً كانت مادي

    In this research, CNRs have been synthesized using pyrolysis of plastic waste(pp) at 1000 ° C for one hour in a closed reactor made from stainless steel, using magnesium oxide (MgO) as a catalyst. The resultant carbon nano rods were purified and characterized using energy dispersive X-ray spectroscopy (EDX), X-ray powder diffraction (XRD). The surface characteristics of carbon rods were observed with the Field emission scanning electron microscopy (FESEM). The carbon was evenly spread and had the highest concentration from SEM-EDX characterization. The results of XRD and FESEM have shown that carbon Nano rods (CNRs) were present in Nano figures, synthesized at 1000 ° C and with pyrolysis temperature 400° C. One of t

The paper proposes a methodology for predicting packet flow at the data plane in smart SDN based on the intelligent controller of spike neural networks(SNN). This methodology is applied to predict the subsequent step of the packet flow, consequently reducing the overcrowding that might happen. The centralized controller acts as a reactive controller for managing the clustering head process in the Software Defined Network data layer in the proposed model. The simulation results show the capability of Spike Neural Network controller in SDN control layer to improve the (QoS) in the whole network in terms of minimizing the packet loss ratio and increased the buffer utilization ratio.
