Abstract The paper deals with the problem of enhancement cooling recycled water in industry. authors developed a new design hybrid tower fill pack consisting inclined-corrugated contact plates and tube radiator. flow during process flows inside radiator to avoid direct air, preventing biofouling process. In addition, external surface is modified by finning for heat transfer intensification. pur...
. فیلتر پیشنهادی دارای فرکانس قطع db 3- در 2.38 ghz و باندگذر این فیلتر، از باند عبور به باند قطع که معمولاً از فرکانس قطع db 3- تا فرکانسی که در آن میزان تضعیف به db 20- میرسد برابر با ghz 0.45است. باند قطع این فیلتر با میزان تضعیف db 21- از ghz 2.5 تا23.5ghz است. insertion loss در باند عبور کمتر از db 0.1 و return loss در باند عبور بهتر از db 16. 9- و در باند قطع نزدیک به 0 db میباشد که نشا...
The cooling circuit is an important component of the magnetic drive pump because it prevents demagnetization permanent magnet and damage to containment shell owing a high temperature increase. In this paper, flow field losses are discussed experimentally verified based on numerical simulation methods. Five different lengths couplings were designed, distribution, rate, loss variation laws analyz...
INTRODUCTION Breastfeeding is the best nourishing method for the health protection, child's growth and development with greatly reduced risks for acute and chronic disorders. The first hours after the childbirth are the most important. The objective of the research. The objective of the research is to establish whether the baby friendly programme affects the infants' biochemical and clinical pa...
Calculation of evaporative heat loss is essential to heat balance calculations. Despite recognition that the value for latent heat of evaporation, used in these calculations, may not always reflect the real cooling benefit to the body, only limited quantitative data on this is available, which has found little use in recent literature. In this experiment a thermal manikin, (MTNW, Seattle, WA) w...
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
Introduction: One way to reduce the level of heat strain is to use personal evaporative cooling coats. such as the wrist, ankle, head and neck. The purpose of this study is to design, construct, and determine the cooling power of local cooling coatings and evaluate their efficiency in improving perceptual indicators in the laboratory. Materials and Methods: Initially, the design and constructio...
