Removal of bacteria by clinoptilolite rich mineral and its surfactant modified forms
Batch experiments were carried out to understand the potential values of clinoptilolite rich mineral and its surfactant modified forms in the removal of Gram-positive and Gram-negative bacteria. Zeta potential and Fourier ...
Development of flexible zein-wax composite and zein-fatty acid blend films for controlled release of lysozyme
The aim of this study was controlled release of lysozyme by modification of hydrophobicity and morphology of zein films using composite and blend film making methods. The incorporation of beeswax, carnauba or candelilla ...
Least square approximate motion generation synthesis of spherical linkages by using Chebyshev and equal spacing
In this paper, approximate motion synthesis of spherical linkages is presented. Rigid body guidance of a spherical four-bar mechanism is performed by a spherical RR open chain. In the first step, position of a point on ...
Calcined and natural frustules filled epoxy matrices: The effect of volume fraction on the tensile and compression behavior
The effects of calcined diatom (CD) and natural diatom (ND) frustules filling (0–12 vol.%) on the quasistatic tensile and quasi-static and high strain rate compression behavior of an epoxy matrix were investigated ...
Morphological and molecular identification of pennate diatoms isolated from Urla, İzmir, coast of the Aegean Sea
Diatoms represent an important class of aquatic phototrophs. They are not only one of the major contributors to global carbon fixation, but also play a key role in the biogeochemical cycling of silica. Molecular ...
Effects of spaceflight on cells of bone marrow origin
(Turkish Society of Hematology, 2013)
Once only a subject for science fiction novels, plans for establishing habitation on space stations, the Moon, and distant planets now appear among the short-term goals of space agencies. This article reviews studies that ...
The prognostic value of tumor-stroma proportion in laryngeal squamous cell carcinoma
(Federation of Turkish Pathology Societies, 2013)
Objective: Tumor-stroma proportion of tumor has been presented as a prognostic factor in some types of adenocarcinomas, but there is no information about squamous cell carcinomas and laryngeal carcinomas. Material and ...
Naturally occurring arsenic in terrestrial geothermal systems of western Anatolia, Turkey: Potential role in contamination of freshwater resources
Arsenic (As) contamination in terrestrial geothermal systems has been identified in many countries worldwide. Concentrations higher than 0.01mg/L are detrimental to human health. We examined potential consequences for As ...
