A new adsorptive square-wave stripping voltammetric method for the trace analysis of germanium
(Hacettepe University, 2008)
The adsorptive stripping voltammetric determination of trace amounts of germanium(IV) based on the adsorptive accumulation of the germanium(IV)-N-(2-hydroxyphenyl)-3-hydroxysalicylaldimine complex on the hanging mercury ...
Optimization of separation of several sulfonamides in acetonitrile-water binary mixtures by using symmetry shield RP-8 column
(Hacettepe University, 2009)
In this work, the proportion of organic modifier of the hydro-organic mobile phase was optimized in order to separate twelve compounds namely sulfaguanidine, sulfanilamide, sulfadiazine, sulfathiazole, sulfamethazine, ...
Detection of aflatoxin M1 in milk and dairy products consumed in Adana, Turkey
(Society of Dairy Technology, 2009)
A total of 70 dairy products consisting of 20 sterilized milk, 10 butter, 20 white cheese and 20 Kashar cheese samples were analysed for aflatoxin M 1(AFM1) by enzyme-linked immunosorbent assay (ELISA). The detection limit ...
Irreversibility analysis of a vapor compression cascade refrigeration cycle
(2009)
Hydrocarbon based energy sources such as coal, oil and natural gas have been diminishing in an increasing speed. Instead of finding alternative energy sources, we have to use the available sources more effectively. By means ...
Determination of noise level of a gas-fired pulse combustor
(2007)
Experimental determination of noise level of a Helmholtz type gas-fired pulse combustor is presented. During the tests, the tail pipe length was varied from 1.9 m to 1.3 m by 10 cm intervals. Noise level measurements were ...
Investigation of irreversibilities in the compression process for alternative refrigerants in a vapor compression refrigeration cycle
(2008)
Irreversibility analyses during compression process are presented for some refrigerants namely, R290, R134a, R12, R22, and R152a in a vapor compression refrigeration cycle. The effects of evaporator temperature, condenser ...
Investigating the antecedents of organization identification
(Doğuş Üniversitesi, 2009)
ABSTRACT: The goal of this paper is to precisely examine the relationship between the attractiveness of organizational identity and strength of identification, and how perceived trust underlines such a possible effect of ...
Characterization of boron doped Cobalt/Zinc acetate composite fibers
(Hacettepe University, 2009)
PVA/cobalt acetate/zinc acetate doped with boron composite fibers were prepared by electrospinning technique. Electrospinning was performed by putting solutions at different applied voltage in a range from 13 to 18 kV. The ...
Gerromorpha and leptopodomorpha (Insecta: Heteroptera) fauna of Southwest Anatolia
(2008)
Bu çalışma, 2000-2002 yılları arasında Güneybatı Anadolu (Antalya, Burdur, Isparta, Denizli, Aydın, Muğla illeri)’da yürütülmüş ve 1627 örnek toplanmıştır. Gerromorpha ve Leptopodomorpha infraordo (Heteroptera)’larına ait ...
Nanofibers by electrospinning of nylon 6 doped with boron
(Hacettepe University, 2009)
In this study, Nylon 6 was successfully cross-linked with boron using formic acid as solution. Electrospinning process was performed by putting hybrid nylon 6/boric acid solutions at different applied voltage in a range ...
