Main-component geochemistry and platinum-group-element potential of Turkish chromite deposits, with emphasis on the Mugla area
(TAYLOR & FRANCIS INC, 2006)
Chromite deposits in Turkey are situated in six different major areas, as are reninants of the Neo-Tethyan oceanic crust. Sizes of the mineralization vary from tens of tons to a few thousand tons. Alpine-type structures ...
The effect of petrochemical industry wastewater composition on the activated sludge microflora
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2006)
In this study, the effect of wastewater composition on the activated sludge microflora has been evaluated. Wastewater samples from the aeration tank of a petrochemical industry wastewater treatment plant were taken and ...
A new approach to quantum well infrared photodetectors: Staircase-like quantum well and barriers
(ELSEVIER SCIENCE BV, 2006)
We present a theoretical investigation of a novel staircase-like quantum well infrared photodetector (QWIP). The proposed structure makes use of quantum wells and barriers with increasing Al content both in the wells and ...
Response of rough and acute surfaces of pyrite with 3-D approach to the flotation
(CONSULTANTS BUREAU/SPRINGER, 2006)
This study presents a new 3-D approach to determine the morphological properties of pyrite particles by Brunauer - Emmett - Teller (BET) nitrogen gas adsorption and Permaran methods. The obtained parameters, which are ...
Adsorption of dithiophosphate and dithiophosphinate on chalcopyrite
(PERGAMON-ELSEVIER SCIENCE LTD, 2006)
Electrochemical behavior of chalcopyrite was investigated in the absence and presence of dithiophosphate (DTP) and dithiophosphinate (DTPI), selective thiols against Fe-sulfides in the flotation of sulfide ores, in ...
Nitrate and pesticides removal from contaminated water using biodenitrification reactor
(ELSEVIER SCI LTD, 2006)
A submerged biological denitrification system was employed to remove selected pesticides, trifluralin, fenitrothion and endosulfan (alpha + beta) and nitrate from drinking water using ethanol as electron donor. When the ...
Soil liquefaction susceptibility and hazard mapping in the residential area of Kutahya (Turkey)
(SPRINGER, 2006)
This study presents the results of both field and laboratory tests that have been undertaken to assess liquefaction susceptibilities of the soils in Kutahya city, located in the well-known seismically active fault zone. ...
gamma-Glutamyltransferase is a promising biomarker for cardiovascular risk
(CHURCHILL LIVINGSTONE, 2006)
Oxidative stress plays a crucial rote in a variety of clinical settings of atherogenesis, and mediates many pathways linked to atherosclerosis and inflammation. gamma-Glutamyttransferase (GGT), an enzyme responsible for ...
Swelling characterization of polyelectrolyte poly(hydroxamic acid) hydrogels in aqueous thiazin dye solutions
(TAYLOR & FRANCIS INC, 2006)
In this study, swelling behavior of polyelectrolyte poly(hydroxamic acid) (PHA) hydrogels have been investigated in aqueous thiazin dye solutions. PHA hydrogels were prepared by free radical polymerizations of acrylamide ...
Structural and geomorphological aspects of the Kat landslides (Tokat-Turkey) and susceptibility mapping by means of GIS
(SPRINGER, 2006)
Kat County, which is located in a slope of hilly region and constructed in the side of a mountain along the North Anatolian Fault Zone, is frequently subject to landslides. The slides occur during periods of heavy rainfall, ...
