Accumulation of metals in roadside soil, dust and pine needles in different characteristic traffic areas
(Parlar Scientific Publications (P S P), 2014)
Heavy metal levels and sources of contamination were investigated in different roadside locations from Ankara and Bursa metropolitan cities in Turkey. A state of the art energy dispersive X-ray fluorescence (EDXRF) ...
Validation of classical quantitative fundamental parameters method using multivariate calibration procedures for trace element analysis in ED-XRF
(Royal Soc Chemistry, 2014)
In this study, the X-ray intensities obtained from 76 soil samples were converted to concentrations by means of the Epsilon software program applying the fundamental parameters method (FP). Various National Institute of ...
Representations by certain octonary quadratic forms whose coefficients are 1, 2, 3 and 6
(World Scientific Publ Co Pte Ltd, 2014)
We determine formulae for the numbers of representations of a positive integer by certain octonary quadratic forms whose coefficients are 1, 2, 3 and 6.
Precision and accuracy of ST-EDXRF performance for As determination comparing with ICP-MS and evaluation of As deviation in the soil media
(Pergamon-Elsevier Science Ltd, 2014)
The present study was conducted to (i) determine the precision and accuracy of arsenic measurement in soil samples using ST-EDXRF by comparison with the results of ICP-MS analyses and (ii) identify the relationship of As ...

Darevskia rudis (BEDRIAGA, 1886) occupies a wide range of altitudes in the Black Sea region of Turkey. A total of 62 individuals of this lizard from three populations/locations at different altitudes (Province of Artvin: ...
Random process generated by the incomplete Gauss sums
(2015)
In this paper we explore a random process generated by the incomplete Gauss sums and establish an analogue ofweak invariance principle forthese sums. We focusour attentionexclusively on ageneralizationofthe limit distribution ...
Microwave assisted synthesis of some novel 2-(3-Chlorobenzyl)-1H-benzimidazole derivatives and determination of their antimicrobial activity and pKa values
(Chiminform Data S A, 2015)
In the present research, synthesis of new 2-(3-chlorobenzyl)-1H-benzimidazole derivatives bearing N-benzylidene, 1,2,4-triazole and N-acylhydrazone moiety is investigated. These novel compounds have been tested for their ...
