one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...

Downslope flows and regions of enhanced cooling have important impacts on society and the environment. Parameterisation of these often subgrid-scale phenomena in numerical models requires a sound understanding of the underlying physical processes, which has been the overarching aim of this work. A numerical model has been used to characterise the development of a region of enhanced cooling in a...

A procedure is described to construct time series of regional surface temperatures and is then applied to interior central California stations to test the hypothesis that century-scale trend differences between irrigated and nonirrigated regions may be identified. The procedure requires documentation of every point in time at which a discontinuity in a station record may have occurred through (...

Field runoff is an important transport mechanism by which pesticides move into the hydrologic environment of intensive agricultural regions such as California's Central Valley. This study presents a spatially explicit modeling approach to extend Pesticide Root Zone Model (PRZM), a field-scale pesticide transport model, into basin level. The approach was applied to simulate chlorpyrifos use in t...

The Janneh dam is a 162-meter high Roller Compacted Concrete arch-gravity dam under construction in the Nahr Ibrahim Valley of Lebanon. The impounded reservoir will supply water, irrigate agricultural areas and generate hydropower [1]. The dam will serve the Northern areas of Greater Beirut Mount Lebanon [2]. The project site is located in highseismicity region. The Peak Ground Accelerations ar...

Most recently, the Flipped Classroom model has drawn the attention of many educators as an effective means of organizing and developing individual competencies. The goal in the university setting at Grand Valley State University, College of Business (GVSU) is to improve cognitive practice and increase learning in the value creation process and the zone of proximal development (ZPD) environment....

The critical zone is defined as the life-sustaining region on and near Earth’s surface that is affected by the interaction of geologic, hydrologic, biologic, and atmospheric processes. Investigations into critical zone processes are needed to reveal how weathering transforms minerals, organic matter, solutions and gases to sustain life. Like all organisms, the health and character of grape vine...

Martin Kenney and Urs von Burg advance two claims in this paper. They assert first that the divergent performance of the Silicon Valley and Route 128 economies can be explained by the path-dependent technological trajectories of their leading industries rather than by the organization of their industrial systems. Second, they claim that these regional dynamics are best understood through an ana...

A study was carried out to investigate the effects of meteorological conditions on atmospheric pollutant concentrations in a complex area. In general serious pollution episodes in the urban and suburban environment are not directly caused by sudden increases in the emission of pollutants but results from unfavorable meteorological conditions, These unfavorable conditions may reduce the ability ...
