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 ...
Environment sensing systems and positioning systems such as GPS (Global Positioning System) are requirements for logistics supply chains, especially refrigerated cargo systems that require environment sensing data. In this paper, we state our system requirements and compare our proposed solution with other existing solutions. Our proposed system focuses on the cold chain tracking system to prov...
Nowadays, most people living in large cities have lived indoors. Especially in summer, high relative humidity, elevated air temperatures and bright sunshine can sometimes combine to produce an uncomfortable indoor environment. Therefore, people want to increase the quality of indoor environment. An air conditioning system can provide comfort for occupants by lowering both the air temperature an...
Green roofs have the potential to function as islands of biodiversity within urban and suburban environments. However, plant diversity is constrained by the harsh environment of a green roof, especially summertime water deficit and heat stress. We hypothesized that Sedum species, which are highly tolerant of the roof-top environment, would reduce peak soil temperature and increase performance o...
this paper discovers the necessary variables need for creating models for tacit knowledge acquisition, especially in medical care services. the case studied here, was knowledge of diagnosing and time of delivery in twin pregnancy with nuchal translucency screening. this paper covers the empirical work undertaken on semi-structured interview based on thematic analysis. with regard of theoretical...
Commonly, immersive and virtual reality systems simulate real environments exploiting 3D computer graphics. This entails a considerable work to be done in models development and objects textures mapping in order to obtain a good degree of realism. Furthermore, the excessive complexity and the high rendering quality of the models can compromise system performance, especially in a web environment...
Basic research on early ontogeny of body functions is carried out mainly in domestic bird species. Summarizing the results, it can be concluded that in birds the development of body functions but also of adaptation mechanisms related to changes in incubation environment starts early during the embryonic phase. However, during the final incubation period bird embryos, especially of precocial spe...
