Antioxidant activity tests on novel triterpenoids from Salvia macrochlamys
(Arkat Usa Inc, 2007)The methanol extract of Salvia macrochlamys Boiss. and Kotschy was fractionated on a silica gel column to yield a group of terpenic compounds. After separation and cleaning, seven known and three new terpenoid compounds ... -
Rankings of Tourism and Hospitality Departments: A Case of Turkey
(Routledge Journals, Taylor & Francis Ltd, 2007)Although there has been a long tradition of ranking departments on the basis of research productivity, this phenomenon is relatively new in tourism research. This paper develops a conceptualized ranking scheme of academic ... -
Comparison of three methods for the estimation of total intracranial volume - Stereologic, planimetric, and anthropometric approaches
(Lippincott Williams & Wilkins, 2007)There is a well-known close relationship between the total intracranial volume (TIV) and the brain size. Several studies in different countries have estimated the cranial capacity, which indirectly reflects the brain volume. ... -
Cultivation of Agaricus bisporus on some compost formulas and locally available casing materials. Part II: Waste tea leaves based compost formulas and locally available casing materials
(Academic Journals, 2007)Three compost formulas (formula I, formula II, and formula III) based waste tea leaves and using some activator materials such as wheat bran, chicken manure and pigeon manure were studied for Agaricus bisporus cultivation. ... -

Polynomial solution of the most general linear Fredholm-Volterra integrodifferential-difference equations by means of Taylor collocation method
(Elsevier Science Inc, 2007)In this paper, a Taylor collocation method has been presented for numerically solving the high-order general linear Fredholm-Volterra integrodifferential-difference equations with variable coefficients under the mixed ... -
Sources and distribution of trace metals in the Saricay Stream basin of southwestern Turkey
(Springer, 2007)Seasonal variation of the concentrations of trace metals ( Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) were measured by ICP-AES in the water and sediment from the Saricay Stream, Geyik Dam and OrtakoyWell in the same basin. ... -
Approximate solution to linear complex differential equation by a new approximate approach
(Elsevier Science Inc, 2007)The purpose of this study is to give a Taylor polynomial approximation for the solution of high-order linear complex differential equations with variable coefficients and mixed conditions about any point. For this purpose, ... -
Cultivation of Agaricus bisporus on wheat straw and waste tea leaves based composts using poplar leaves as activator material
(Academic Journals, 2007)This study was carried out to determine pin head formation time and mushroom yield of Agaricus bisporus on some casing materials. Composts were prepared basically from wheat straw and waste tea leaves using poplar leaves ... -
Cultivation of Agaricus bisporus on wheat straw and waste tea leaves based compost formulas using wheat chaff as activator material
(Academic Journals, 2007)This study was designed to determine the pin head formation time and yield values of Agaricus bisporus on some casing materials. Composts were prepared basically from wheat straw and waste tea leaves by using wheat chaff ... -
Statistical principal components analysis for retrieval experiments
(Wiley, 2007)In this article, the statistical principal components analysis (PCA) is proposed as a method for performance comparisons of different retrieval strategies. It is shown that the PCA method can reveal implicit performance ... -
Does Liriomyza cicerina affect the yield of chickpeas (Cicer arietinum)?
(Springer, 2007)Liriomyza cicerina (Rondani, 1875) (Diptera: Agromyzidae) is an important pest on chickpea (Cicer arietinum L.) in some regions of Turkey. The objective of this study was to determine whether the populations of L. cicerina ... -
Measurement and comparison of complex impedance of silicon p-i-n photodiodes at different temperatures
(Maik Nauka/Interperiodica/Springer, 2007)The dark alternating current (ac) parameters of BPW34 and BPW41 (Vishay-Telefunken) silicon p-i-n photodiodes arc measured and compared at different temperatures using the impedance spectroscopy technique. The impedance ... -
Investigation of heat capacities of proteins by statistical mechanical methods
(Elsevier Science Bv, 2007)In this study additional heat capacity of the proteins in water dissociation have been investigated by statistical mechanical methods. For this purpose, taking electric field E and total dipole moment M as thermodynamical ... -
Electronic aspects of the martensitic transition in Ni-Mn based Heusler alloys
(Elsevier, 2007)The martensitic transformation temperature Ms depends linearly on the valence electron concentration for Ni-Mn-X Heusler systems where X is a group III-group V element. However, the slopes of the linearity are different ... -
Interannual variability of fecundity and egg size of an invasive cyprinid, Carassius gibelio: Effects of density-dependent and density-independent factors
(Taylor & Francis Inc, 2007)A population of the invasive Prussian carp (Carassius gibelio) was examined over a three-year period in a mesotrophic reservoir to find out interannual variations of fecundity and egg size and the influence of maternal ... -
The removal of colour, carotene and acidity from crude olive oil by using sepiolite
(Wiley, 2007)The capacity of sepiolite to adsorb colouring matters in olive oil was studied. The effects of adsorption time, temperature and solid:liquid ratio were selected as parameters. The effect of bleaching of olive oil was ... -
A Taylor method for numerical solution of generalized pantograph equations with linear functional argument
