Experimental investigation of gamma-ray attenuation coefficients for granites
(PERGAMON-ELSEVIER SCIENCE LTD, 2012)
The linear attenuation coefficients of gamma-rays for some granite samples have been measured at 662, 1773 and 1332 keV. They gamma-rays have been obtained from Cs-137 and Co-60 sources respectively and the measurement ...
Experimental and computational studies of bis[bis(2-furyl)glyoximato]nickel(II)
(TAYLOR & FRANCIS LTD, 2012)
Bis[bis(2-furyl)glyoximato]nickel(II) has been synthesized and characterized by infrared (IR), H-1-NMR, C-13-NMR, and UV-Vis spectroscopy, elemental analysis, and single-crystal X-ray diffraction. The new complex crystallizes ...
Additional records of Gerromorpha (Hemiptera: Heteroptera) and redescription of Rhagovelia nigricans nigricans (Burmeister, 1835) from Anatolia (Turkey)
(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2012)
In this study, 1210 adult specimens of the infraorder Gerromorpha (Hemiptera: Heteroptera) were collected from 47 different localities in eastern Anatolia, the Black Sea region, Kelkit Valley, and Hatay from 2006 to 2010, ...
Radiation Absorption Properties of Different Plaster Samples
(AMER INST PHYSICS, 2012)
Although the plaster is one of the oldest known synthetic building materials, nowadays, it is used as interior coating of walls and ceilings of buildings. Thus measuring its radiation shielding properties is vital. For ...
Measurements of natural radionuclides in some soil samples from Amasya (Turkey)
(AMER INST PHYSICS, 2012)
The soil on the earth's crust is a source of continuously exposure to human beings. The amount of radioactivity in soil depends upon the type of soil and its uses. Amasya is located on the inside of the Department of the ...

(PRAISE WORTHY PRIZE SRL, 2012)
Axial flux permanent magnet machines using high energy magnets have been increasingly employed for several applications. This work presents a new design procedure for an axial flux permanent magnet synchronous generator ...
Fuzzy TOPSIS Method in Supplier Selection and Application in the Garment Industry
(INST CHEMICAL FIBRES, 2012)
In today's world where intensive competition exists between enterprises, it is of great importance to work in cooperation with the right suppliers. Selection of the right suppliers is a significant factor in the success ...
THE PRIMARY SCHOOL STUDENTS' ATTITUDE AND ANXIETY TOWARDS SCIENCE
(SCI METHODICAL CTR-SCI EDUCOLOGICA, 2012)
In this study, the relationships between the attitudes and anxieties of 6th, 7th and 8th grade students about science have been examined. The data have been gathered from a personal data form, anxiety towards science and ...
Modules that have a supplement in every cofinite extension
(HELDERMANN VERLAG, 2012)
Let R be a ring and M a left R-module. An R-module N is called a cofinite extension of M in case M subset of N and N/M is finitely generated. We say that M has the property (CE) (resp. (CEE)) if M has a supplement (resp. ...
STRONGLY RADICAL SUPPLEMENTED MODULES
(SPRINGER, 2012)
Zoschinger studied modules whose radicals have supplements and called these modules radical supplemented. Motivated by this, we call a module strongly radical supplemented (briefly srs) if every submodule containing the ...
