( Potentiometric and spectrophotometric determination of fluoride in some natural waters of Dogubayazit region). [Dogubayazit yoresindeki bazi su kaynaklarinda spektrofotometrik ve potansiyometrik yontemerle fluorur miktarlarinin arastirilmasi.]
(1983)Seventeen samples, out of 23, contained fluorides higher than recommended control limits for fluorides in drinking waters by WHO. It has been reported by many workers who studied in the area for the last 10 yr, that dental ... -
Quantitative determination of escin. A comparative study of HPLC and TLC-densitometry
(1994)Escin was quantitatively determined by both HPLC and TLC-densitometric techniques in horse-chestnut extracts. The results were found to be accurate, reproducible and in excellent agreement. -
Fixed-bed pyrolysis of cottonseed cake: Product yields and compositions
(Taylor & Francis, 1997)Fired-bed pyrolysis experiments have been conducted on a sample of cottonseed cake to determine the possibility of being a potential source of renewable fuels and chemical feedstocks. The effects of heating rate, pyrolysis ... -
Hydropyrolysis of extracted Euphorbia rigida in a well-swept fixed-bed tubular reactor
(Taylor & Francis Inc, 2002)Tubular reactor fixed-bed hydropyrolysis experiments have been conducted on a sample of extracted Euphorbia rigida to determine the possibility of being a potential source of renewable fuels and chemical feedstock. The ... -
GIS for urban conservation: Change detection and priority determination in historical Turkey

Carbon supported Ru-Se as methanol tolerant catalysts for DMFC cathodes. Part II: preparation and characterization of MEAs
(Springer, 2007)Cathode catalyst layers were prepared and characterized as part of membrane electrode assemblies (MEA) and catalyst coated membranes (CCM) on the basis of carbon supported methanol tolerant RuSe (x) catalysts. Preparation ... -
Effect of length-to-diameter ratio of core sample on concrete core strength - Another look
(Amer Soc Testing Materials, 2008)Cores with diameters of 144,94,69, and 46 mm and length-to-diameter(1/d) ratios of 0.75,1,1.25,1.5,1.75, and 2, were removed from beam specimens produced from eight different concrete mixtures. Compressive strength tests ... -
Effects of fritted borax solid wastes on the properties of brick bodies
(2009)Brick is a structural ceramic material that, in modem times, is made by pressing clay into blocks and firing them to a requisite hardness in a kiln. In order to improve quality and usage fields of brick, it is obvious that ... -
Theoria, praxis, poiesis: A continuum scheme
(2011)The present age provides that the new production technologies are in a continuous experimental production in terms of both quantitative and rapidness criteria. Thinking and testing speed comes closer with these experiences. ... -
U-type assembly line balancing with ergonomic factors for balance stability [Sürdürülebi·li·r denge i·çi·n ergonomi·k faktörleri· i·çeren u-ti·pi· montaj hatti dengelemesi·]
(2012)In this paper, we present a new mathematical model of U-type assembly line balancing problem based on the performance factors of the operators, the amount of energy used and incompatibility between the tasks. Many researchers ... -
Some physical effects of reaction rate on PbS thin films obtained by chemical bath deposition
(Elsevier Science BV, 2013)Thin films of polycrystalline lead sulfide (PbS) have been deposited on glass substrates at 303 +/- 1 K using chemical bath deposition (CBD). The precipitation of PbS on solid surfaces under four different reaction conditions ... -
Effects of Modification of Glassy Phase Composition on Sintering Temperature of Sanitaryware
(Gazi University, Fac Engineering Architecture, 2013)In this study, the effect of glassy phase viscosity and chemical composition of sanitaryware body was investigated. Additionally, the effects of these parameters on the sintering temperature were researched. The amount of ... -
Determination of the Freezing Effect on Unconfined Compression Strength and Permeability of Saturated Granular Soils
(Geomate Int Soc, 2015)Artificial ground freezing usage gradually rises in civil engineering applications as a soil supporting system. However, many unknown fundamental parameters have been still waiting discovery, especially for granular soil. ... -
Strained band edge characteristics from hybrid density functional theory and empirical pseudopotentials: GaAs, GaSb, InAs and InSb
