The main causes of destructive steam and gas explosions with catastrophic environmental consequences during the accidents at Fukushima-Daiichi NPP were loss tightness passive safety systems reactor residual fuel removal system critical heat function in spent nuclear holding tank . lesson Fukushima accident for Ukraine's power industry is need to anticipate possibility unlikely emergency events ...

Recently, in a previous study, we experimentally showed the existence of an optimal injected steam mass flow rate, per unit length, ϕopt, which produces maximal recovery condensate preformed chamber with elliptical cross section horizontal semi-major axis. Mutatis mutandis, this work, present experimental studies chambers: one and other circular. In both cases, also found unique values. These c...

Indonesia is a country with significant portion of its territory consisting water bodies, which makes it prone to flooding. Therefore, the development an early warning system in form flood alarm prototype crucial. This research designed using Design Thinking models method. Based on created prototype, STEAM-based learning can be implemented enable students learn physics through scientific steps....

This report examines the potential of polymer flooding to recover viscous oils, especially in reservoirs that preclude the application of thermal methods. A reconsideration of EOR screening criteria revealed that higher oil prices, modest polymer prices, increased use of horizontal wells, and controlled injection above the formation parting pressure all help considerably to extend the applicabi...

Laboratory measurements of the effects of steam injection on the electrical conductivity of sands can aid in the interpretation of electrical surveys used to monitor subsurface steam-injection projects. The effect of variations in injected steam quality was measured in the experiments presented here. The injection of low-quality steam, boiled from a 0.01 mol/L NaCl solution, into clean sand sat...

Extraction of soybean seed proteins for two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and mass spectrometry analysis is challenging and inconsistent. In this study, we compared four different protein extraction/solubilization methods-urea, thiourea/urea, phenol, and a modified trichloroacetic acid (TCA)/acetone-to determine their efficacy in separating soybean seed proteins by 2D...
