One of the main objectives of the companies is to serve society. Companies, in fulfilling this objective, managers and employees, government, partners and customers are obliged to observe. Intense competition in the day, ...
Statistical downscaling of monthly precipitation using NCEP/NCAR reanalysis data for tahtali river basin in Turkey
(2010)
Statistical downscaling methods describe a statistical relationship between large-scale atmospheric variables such as temperature, humidity, precipitation, etc., and local-scale meteorological variables like precipitation. ...
Photodimerizations of hydroxy- and benzoylated 4-azachalcones and quantum chemical investigation of the reactions
(2010)
Photodimerization reactions of compounds 4-6 gave four new cyclobutane-containing compounds (7-9) with full control over the stereochemistry at the four stereogenic centers. These new cyclobutane- containing compounds had ...
Pre- and post-cyclic loading strength of silica-grouted sand
(2010)
The aim of this study is to investigate whether there is a loss in the strength of fine- to medium-grained colloidalsilica-grouted sand after cyclic loading. First, the rheological properties of colloidal silica grouts, ...
Determination of alkali-silica reaction effects of zeolitic tuff addition on the different aggregates
(2010)
The aim of this study is to determine the alkali-silica reaction (ASR) related characteristics of crushed stones that are produced from rocks of perlite, andesite and limestone when zeolitic tuff (ZT) is used in the mortar ...
Complexation of metal ions with double-armed diazadithia lariat ether carrying anthracene moieties in acetonitrile-dioxane
(2010)
A new 14-membered crown ether with nitrogen-sulfur donor atom carrying two anthryl groups was designed and synthesized by the reaction of the corresponding macrocyclic compound and 9-(chloromethyl) anthracene. The influence ...
Analysis of heat pumps with zeotropic refrigerant mixtures by taguchi method
(2010)
The goal of this work is to determine the optimum set of parameters by using the Taguchi method in vapour compression heat pump systems. The experimental apparatus consist of an air-to-liquid vapor compression heat pump, ...
Customer risk perceptions of internet banking - A study in turkey
(2010)
Technological developments in electronics have lead to the introduction of technology-based self-service systems resulting in the reorganization of several industries offering their services in electronic format known as ...
