(Chemical Publishing Co., 2011)
The present work describes the chemical composition and antimicrobial activity of the essential oil of Myosotis alpestris F.W. Schmidt subsp. alpestris (Boraginaceae). The essential oil was obtained from all parts of the ...
Ecological and economical advantages of solar water heating systems used by forest villagers in Gumushane, Turkey
(WFL Publisher Ltd., 2013)
Clean and safety energies are crucial for our world energy requirements. Therefore, the environmental awareness on the topic will also increase the use of clean energy especially in rural and urban areas. A solar energy ...
Well-posedness of fractional parabolic differential and difference equations with Dirichlet-Neumann conditions
(Texas State University - San Marcos, 2014)
We study initial-boundary value problems for fractional parabolic equations with the Dirichlet-Neumann conditions. We obtain a stable difference schemes for this problem, and obtain theorems on coercive stability estimates ...

(TMMOB - Jeoloji Muhendisleri Odasi, 2011)
In this study, use of Rock Quality Designation (RQD) and Volumetric Joint Count (Jv) parameters for prediction of block volume from Harşit Granitoid exposed in Dogankent (Giresun) area, was investigated. For this purpose, ...
On the solutions of time-fractio3nal generalized hirota-satsuma coupled-KDV equation with modified riemann-liouville derivative by an analytical technique
(Editura Academiei Romane, 2015)
In this paper, the fractional variational iteration method (FVIM) was implemented to solve timefractional generalized Hirota-Satsuma coupled-KDV equation with modified Riemann-Liouville derivative. A new application of ...
Use of polyvinyl chloride (PVC) powder and granules as aggregate replacement in concrete mixtures
(Walter De Gruyter Gmbh, 2016)
Concrete is one of the materials in which polymer wastes are utilized. Generally, these wastes are added at specific rates in scientific studies but an important problem of waste polymers is size irregularity. Even when ...
