In this paper, we consider the optimization of temperature conditions and thermo-stressed state a concrete gravity dam made extra lean roller-compacted constructed in climate corresponding to Pskem HPP Republic Uzbekistan. We show need take into account effect solar radiation on heating mass during layer-by-layer construction dam. A methodology was used estimate radiation, considering cloud cov...

The egg development and early life history of Korean spotted sleeper, Odontobutis interrupta which is Korean endemic species from Sora-choen was investigated. The Korean spotted sleeper were caught at Sora-myeon, Yeosu-si, Jeollanamdo, from Korea at May in 2014. The fertilized eggs were 4.23 ± 0.05 mm in long diameter and had oil globules. Hatching time of the embryo began about 442 hr 14 min a...

This paper illustrates the phenomenon of the critical speed in the range 100300 km/h. A real explanation and a precise calculation of the critical speed seems to rest an unresolved problem in many cases. Some authors, analogous to “Mach effect”, have attributed this phenomenon to the reaching the Rayleigh wave speed of substructure by trains. But this explanation can’t be thorough in many cases...

This study evaluates the performance and emission characteristics of an orange peel biodiesel blended with cashew nut shell liquid. It investigates efficacy liquid in reducing nitrogen oxide (NOX) emissions resulting from combustion biodiesel, while optimizing its performance. The was prepared via transesterification. obtained by reacting oil produced through Soxhlet extraction methanol presenc...
