environmental effects of gol-e-gohar iron ore mine on groundwater of the area

gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...

Effects of thermal neutrons on living cells. III. Estimation of absorbed dose in amoeba irradiated by thermal neutrons.

河 合建一,牧 廣 利,赤 星光彦1京 都大学原子炉実験所,大 阪府泉南郡熊取町 野田,〒590-04 An absorbed dose in amoeba irradiated by thermal neutrons was estimated. Nuclear events following to thermal neutron capture were divided into 6 parts. More than 99% of absorbed dose was estimated to be due to capture ƒÁ-rays. Absorbed dose due to recoil nucleus following to the emission of capture ƒÁ-rays and that due to ƒÀor ƒÁ-rays emitted ...

Creep Behavior of Al-Si Die-Cast Alloys

Commercial, aluminum die-cast alloys are subject to long-term stresses leading to viscoelastic material responses resulting in inefficient engine operation and failure. Constant load creep tests were conducted on aluminum die-casting alloys: B-390, eutectic Al-Si and a 17% Si-Al alloys. Rupture occurred in the primary creep regime, with the eutectic alloy having the longest times to failure. Pr...

Effect of stress and temperature on the micromechanics of creep in highly irradiated bone and dentin.

Synchrotron X-ray diffraction is used to study in situ the evolution of phase strains during compressive creep deformation in bovine bone and dentin for a range of compressive stresses and irradiation rates, at ambient and body temperatures. In all cases, compressive strains in the collagen phase increase with increasing creep time (and concomitant irradiation), reflecting macroscopic deformati...
