Soil erosion is one of the important and worldwide environmental and economic issues. High amount of sediments accumulations behind the different structures such as dams requires several attempts to minimize their potential risks. Therefore, some quantified data will be needed in order to recognize those critical areas which requires urgent conservation. Since conventional procedures are time c...

The United States has a well-documented teacher shortage crisis. Areas such as Science, Technology, Engineering and Mathematics (STEM) continue to experience shortages. Since teachers have the greatest impact on student achievement, lack of highly qualified potentially affects academic economic stability States. This paper provides model recommendations for addressing shortages in STEM other cr...

to identify critical sediment sources in large catchments, using easily available terrain information at a regionalscale, a methodology was developed to obtain a qualitative assessment necessary for environmental management.fargas et al method was employed in the research. the study was carried out in one of the sub-basins of hableh roodbasin called dehnamak in the arid and semiarid climate of ...

Finite state machines and their extensions are widely used for system modeling and analysis. Often, the models themselves do not provide much insight into critical system areas which need to be observed (or monitored) and those system areas that lead to effective control. The issue is mostly left to the discretion of the development team which often has limited domain knowledge. In this paper, ...

the idea is growing among educators that thinking skill needs to be given a direct attention. on one hand, critical thinking is supposed to broaden students’ thinking in all regards (schafersman, 1991); and on the other hand learners’ attitudes towards the second language can affect both their performance in the class and their final accomplishment. to this end, the present study started with t...
