Sulfur and lead isotope investigations of the carbonate-hosted Pb-Zn deposits in the Yahyah region, Kayseri, southern Turkey
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2007)
Carbonate-hosted Pb-Zn deposits are common in the Yahyali region (Taurus Belt) with galena the most abundant sulfide mineral. The mean delta S-34 values for Goynuk, Celaldagi Desandre, Demircilik, Tekke, Havadan and Sucati ...
In vitro antioxidant activity of polyphenol extracts with antiviral properties from Geranium sanguineum L
(PERGAMON-ELSEVIER SCIENCE LTD, 2005)
Recent evidence shows that plant polyphenols exhibit antioxidant and radical scavenging properties. By three separate and complementary methods - DPPH assay, beta-carotene-linoleic acid assay and NBT-reduction assay it was ...
The protein sparing effects of high lipid levels in diets for rainbow trout (Oncorhynchus mykiss, W. 1792) with special reference to reduction of total nitrogen excretion
(LAB RESEARCH FISH DISEASES, 2002)
This research sought to develop low-protein, high-energy (less-polluting) diets for rainbow trout to properly utilize protein and reduce total nitrogen excretion. Duplicate groups of rainbow trout were fed one of four ...
Ultimate loads for eccentrically loaded model shallow strip footings on geotextile-reinforced sand
(ELSEVIER SCI LTD, 2009)
A series of tests were carried out with an eccentrically loaded model surface shallow strip footing on reinforced dense sand to investigate the decrease of the ultimate loads with increasing eccentricity and to compare the ...
Timing of neotectonic fracturing by fission track dating of obsidian in-filling faults in the Ikizdere-Rize area, NE Black Sea region, Turkey
(WILEY-BLACKWELL, 2002)
There are several NE-SW- and NNW-SSE-trending sets of neotectonic faults that are infilled with obsidians in the Ikizdere-Rize district of the NE Black Sea region, Turkey. Using the fission-track technique, it is estimated ...
Relationship between the swelling process and the releases of water soluble agrochemicals from radiation crosslinked acrylamide/itaconic acid copolymers
(SPRINGER-VERLAG, 2000)
An attempt was made in this study to relate the releases of water soluble herbicide (sodium 2,2 dichloropropionate (Dowpon)) and model fertilizers (ammonium nitrate, potassium nitrate and ammonium sulfate) from the cylindrical ...
Slow Senonian and fast Palaeocene-Early Eocene uplift of the granitoids in the Central Eastern Pontides, Turkey: apatite fission-track results
(ELSEVIER SCIENCE BV, 2004)
Dating and forward modelling of the fission-track data of apatite samples from the Dereli-Sebinkarahisar region, south of Giresun in the Eastern Turkish Pontides, provides quantitative data on the regional tectonics resulting ...
Ab initio calculations of solvent effects on guanine and thioguanine tautomerism
(NATL INST SCIENCE COMMUNICATION-NISCAIR, 2000)
The molecular geometries and the relative energies of the ten most stable tautomers of guanine (G1, G2, G3...etc.) and thioguanine (TG1, TG2, TG3...etc.) have been investigated at the HF/3-21G and HF/6-31G** levels in the ...
Chemical composition, antioxidant and antimicrobial properties of the essential oils of three Salvia species from Turkish flora
(ELSEVIER SCI LTD, 2008)
Essential oils of three different Salvia species [Salvia aucheri var. aucheri (endemic), Salvia aramiensis and Salvia pilifera (endemic)] were screened for their possible antioxidant and antimicrobial properties as well ...
Effects of ekogenous indole butyric acid and callus formation on the anti-oxidant activity, total phenolic, and anthocyanin constituents of mulberry cuttings
(WILEY-BLACKWELL, 2006)
in order to evaluate the effects of exogenous indole butyric acid (IBA) and callus formation on the antioxidant activity, total phenolics, and anthocyanin constituents of Morus, nigra L. and M. alba L. cuttings, we ...
