Frequency optimization of laminated skewed open cylindrical shells
(Walter De Gruyter Gmbh, 2011)
This paper deals with frequency optimization of symmetrically laminated skewed open cylindrical shells. The design objective is the maximization of the fundamental frequency and the design variable is the fiber orientations. ...
Abrasion Resistance of Cement Mortar with Different Pozzolanic Compositions and Matrices
(Asce-Amer Soc Civil Engineers, 2011)
Abrasion of concrete occurs due to scraping, rubbing, skidding, or sliding of objects on its surface. The abrasion resistance of concrete is influenced by a number of factors, such as compressive strength, surfacing finish, ...
Mineralogy and whole rock geochemistry of late Cretaceous sandstones from the eastern Pontides (NE Turkey)
(E Schweizerbartsche Verlags, 2011)
This study focuses on Upper Cretaceous sandstones of the Eastern Pontides to identify the source area, subaerial weathering level, and tectonic environment. Thirty four sandstone samples from six stratigraphic sections ...
Migrating magmatism in a continental arc: Geodynamics of the Eastern Mediterranean revisited
(Pergamon-Elsevier Science Ltd, 2011)
The eastern Pontide orogenic belt in Turkey offers a critical region to evaluate the geodynamic evolution of the eastern Mediterranean region during the late Mesozoic-Cenozoic. Here we synthesize results from our exhaustive ...
Effect of plant growth-promoting rhizobacteria and manure on yield and quality characteristics of Italian ryegrass under semi arid conditions
(2011)
Plant growth-promoting rhizobacteria (PGPR) appeared as a promising alternative for organic fertilization. A field experiment was carried out to evaluate the effects of PGPR and solid cattle manure application on yield, ...
Estimation of the carbon to nitrogen (C:N) ratio in compostable solid waste using artificial neural networks
(2011)
Organic waste constitutes a majority of all municipal solid waste (MSW), a fact which yields some unfavorable results at open dumps, sanitary landfills, and incineration plants. As part of an integrated solid waste management ...
The effect of antifreeze admixtures on compressive strength of concretes subjected to frost action
(Gazi Universitesi, 2011)
This study aims to determine the effect of antifreeze admixture used in the concretes subjected to frost action on the concrete compressive strength. Three groups of concrete samples of C30 class were prepared with antifreeze ...
Effect of the inclination of coal seam on face disassembly time in mechanized longwall
(2011)
Production rate and quantity in underground mechanized coal mines are quite high compared to other methods. However, in mechanized systems, there are also certain factors that affect production rate and quantity. One of ...
Using landsat data to determine land use/land cover changes in gümüşhane, Turkey
(2011)
Sustainable land use and development require timely, accurate and detailed information of land resources as well as changes in the land resource. 'What is changing in where' question is answered by multiple observations ...
