Herein, we undertake a geomorphological analysis in which spatial and temporal trends of bed and bank erosion along an 18-km length of Hotophia Creek, Mississippi, are estimated for the period between 1961 and 2050. The evaluation was undertaken for two scenarios of channel response to channelization during 1961–1963. One scenario represents the ‘actual’ response of the channel and includes the...

This paper presents a critique of several selected studies in the areas of officer retention and grade structure. These studies are investigated to determine what methods of approach and analytic techniques were employed in accomplishing the objectives of the study group. An assessment is made of the degree of success or failure realized by each study. In discussing officer grade structure stud...

Three-dimensional (3D) intensity distributions generated by light passing through conformal phase masks can be modulated by the absorption property of photosensitive materials. The intensity distributions have extremely long depth of focus, which is proportional to the size of the phase masks, and this enables one to pattern thick (approximately 100 microm), nanoporous structures with precise c...

in the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. different goals may be used for determining optimum cut-off grade. one of...

Why regularities in personality can be described with particular dimensions is a basic question in differential psychology. Nonhuman primates can also be characterized in terms of personality structure. Comparative approaches can help reveal phylogenetic constraints and social and ecological patterns associated with the presence or absence of specific personality dimensions. We sought to determ...

BACKGROUND Multiple treatment options exist for the management of renal cell carcinomas. Preoperative evaluation of clear cell renal cell carcinoma (CRCC) grades is important for deciding upon the appropriate method of therapy. We hypothesize that susceptibility weighted imaging (SWI) is sensitive enough to detect intratumoral microvessles and microbleeding in renal cell carcinoma, which can be...

background endemic goiter is present in most parts of iran. iron deficiency adversely affects the physiology of thyroid. the initial steps of thyroid hormone synthesis are catalyzed by thyroperoxidases and are dependent on iron. in many developing countries, children are at high risk of both goiter and iron deficiency anemia. in addition, iron deficiency may alter central nervous system control...

In order to research the evolution of microstructures and properties SCM435 wire rod after annealing with different initial structures, two kinds microstructure (B+M F+P) rods were used simulate spheroidizing annealing, softening stress relief processes respectively. The results show that under same process conditions, spheroidization grade B+M was 1-2 higher than F+P, while hardness does not d...
