In this paper, the challenge is to increasing of the heat exchanger performance by placing different size balls inside the tubes.the development of previous studies to enhance relatively bad case of heat transfer where the inserting (a large ball and then a small ball) to collide the water molecules in the ball and generate turbulent flow (Reynolds
A 50-year-old male presented for loss of consciousness.He was initially treated with intravenous epinephrine and fluids, and an electrocardiogram (ECG) displayed an ST-segment elevation in lead aVR with global ST-segment depressions.A subsequent left heart catheterization revealed that the middle segment of the left anterior descending artery (LAD)
The human subcortex Sunglasses comprises hundreds of unique structures.Subcortical functioning is crucial for behavior, and disrupted function is observed in common neurodegenerative diseases.Despite their importance, human subcortical structures continue to be difficult to study in vivo.Here we provide a detailed account of 17 prominent subcortica
Building geometry design decisions are important for energy efficiency and daylight performance.Sensitivity analysis, coupled with optimization, is an important approach to investigate and optimize building geometry in the early design stage.Incorporating skylights is an important daylighting strategy in commercial buildings; however, skylight-to-f
Wafer-baking ovens are machines that bake liquid batter by heating the interconnected cast plates in a gas oven.The plates in contact with the wafer batter are generally made of the cast material.Although there are many studies on the contents in the recipes of wafer products and the effects of the additives included in the recipes on the quality o
