Attitude of elementary prospective teachers towards science teaching
(Elsevier Science BV, 2012)
The aim of study is to investigate attitude of elementary prospective teachers towards science teaching respect to the gender, grade level and graduation type of high school. The study was carried out during fall semester ...
Stream bank erosion as a source of sediment and phosphorus in grazed pastures of the Rathbun Lake Watershed in southern Iowa, United States
(Soil Water Conservation Soc., 2012)
Livestock grazing of riparian areas can have a major impact on stream banks and stream integrity if improperly managed. The goals of this study were to determine the sediment and phosphorus (P) losses from stream bank soils ...
Spatial variation in some soil properties influencing penetration resistance
(Ankara Univ, 2012)
This study was conducted to assess soil compaction via penetration measurements, to determine soil properties that may influence penetration resistance values and to investigate spatial variation in flavaquent soils where ...
The construction of variable density yield table for scots pine and oriental beech mixed stands in black sea region
(Kastamonu Üniversitesi, 2012)
In this study, variable density yield tables were developed for Scots pine and oriental beech mixed stands in Black Sea Region. The data used in this study were obtained from 162 temporary sample plots measured in evenaged ...
A comparison of chemistry teachers' and grade 11 students' alternative conceptions of 'rate of reaction'
(Sci Methodical Ctr-Sci Educologica, 2012)
The purpose of this study is to compare alternative conceptions of chemistry teachers and Grade 11 students on the subject of 'rate of reaction'. This study was conducted with a total of seventy chemistry teachers and ...
On an inverse scattering problem for a class Dirac operator with discontinuous coefficient and nonlinear dependence on the spectral parameter in the boundary condition
(Wiley, 2012)
On the positive semi-infinite interval, we obtained a generalization of the Marchenko method for a Dirac equation system with a discontinuous coefficient and a quadratic polynomial on a spectral parameter in the boundary ...
Vibration effects examination of cushions used on tractor driving seat

Vibration effect of driver's seat of agricultural tractor which works in land condition has been researched. In this research, three different cushions on driver's seat have been used. These are wool, sponge and cotton. ...
On an inverse scattering problem for a class of Dirac operators with spectral parameter in the boundary condition
(Academic Press Inc Elsevier Science, 2012)
In this work, we consider the inverse scattering problem for a class of one dimensional Dirac operators on the semi-infinite interval with the boundary condition depending polynomially on a spectral parameter. The scattering ...
The influence of moisture content of raw material on the physical and mechanical properties, surface roughness, wettability, and formaldehyde emission of particleboard composite
(Elsevier SCI LTD, 2012)
The objectives of this research were to investigate surface characteristics, physical (thickness swelling) and mechanical (modulus of rupture, modulus of elasticity and internal bond strength) properties, and formaldehyde ...
Karyological studies of some representatives of Tanacetum L. (Anthemideae-Asteraceae) from north-east Anatolia
(Springer Wien, 2012)
The karyotypes of nine Tanacetum taxa distributed in north-east Anatolia, Turkey, were determined and evaluated by cluster analysis and principal-components analysis. Chromosome numbers were 2n = 2x = 18 (8 taxa) and 4x = ...
