The aim of this study was to determine the appropriate bridging liquid for lignites at selective agglomeration. Kerosene, diesel-oil, fuel-oil, spindle oil, heavy neutral, bright stock, light neutral and various surface ...
Influence of some aromatic amino acids on the swelling behavior of acrylamide/maleic acid hydrogel
(SPRINGER VERLAG, 1998)
Influence of some aromatic amino acids (histidine, phenylalanine and tryptophan) on the swelling behavior of acrylamide/maleic acid hydrogel (AAm/MA) prepared by gamma-radiation was investigated. Swelling tests of AAm/MA ...
Organic facies characteristics of the Sivas Tertiary basin (Turkey)
(ELSEVIER SCIENCE BV, 1998)
The Sivas Tertiary Basin is located on top of the Late Cretaceous Neotethys ophiolitic nappes which were abducted onto both the Pontic belt and the Tauric platform. Organic facies characters of Tertiary units in this basin ...
The releases of agrochemicals from radiation induced acrylamide crotonic acid hydrogels
(SPRINGER VERLAG, 1998)
The aim of this work was to test the application of new copolymeric poly(acrylamide/ crotonic acid) (AAm/CA) hydrogels to agrochemicals (sodium 2,2 dichloropropionate (dalapon), ammonium nitrate, potassium nitrate and ...
Sirelina orduensis (foraminifera) a new genus and species from the Maastrichtian of Northeast Anatolia (Golkoy-Ordu)
(MICROPALEONTOLOGY PRESS, 1998)
A new genus and species of foraminifera is described from the Maastrichtian of the Golkoy (Ordu) region of Turkey. It is named Sirelina orduensis n. gen., n. sp. The test of the genus has a microgranular calcereous structure ...
The leaching of SrS with water and the precipitation of SrCO3 from leach solution by different carbonating agents
(ELSEVIER SCIENCE BV, 1998)
The leaching of strontium sulfide (SrS) with water was investigated, and a comparison of Na2CO3 with CO2 as a carbonating agent for the precipitation of SrCO3 from leach solution was done. The effects of variables for ...
Cholesterol granuloma of the maxillary sinus: six cases from the same region
(HEADLEY BROTHERS LTD, 1998)
It is common to find cholesterol granuloma in the mastoid antrum and air cells of the temporal bone, but it is very rare in paranasal sinuses. In the development of this pathology, the key factor is the presence of a closed ...
Palaeomagnetic study of the Karaman and Karapinar volcanic complexes, central Turkey: neotectonic rotation in the south-central sector of the Anatolian Block
(ELSEVIER SCIENCE BV, 1998)
In the Anatolian sector of the Afro-Eurasian collision zone a palaeotectonic collisional phase (Paleocene to Miocene) responsible for emplacement of the Pontide and Tauride orogens has been replaced by a neotectonic phase ...
Effects of nimodipine and isradipine on endothelin-1-induced contraction of pregnant rat myometrium
(ELSEVIER SCIENCE BV, 1998)
The purpose of this study was to investigate the effect of nimodipine and isradipine on endothelin-1-induced contractions of isolated pregnant rat myometrium. Endothelin-1 at 10(-10)-10(-8) M dose-dependently increased the ...
Strategies for reducing solvent toxicity in extractive ethanol fermentation
(HUMANA PRESS INC, 1998)
Extractive fermentation is a widely preferred technique in which the products of fermentation are removed from the fermentation medium by a proper solvent, in order to avoid the inhibitory effects of the products. In this ...
