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 ... -
A Taylor method for numerical solution of generalized pantograph equations with linear functional argument
(Elsevier Science Bv, 2007)This paper is concerned with a generalization of a functional differential equation known as the pantograph equation which contains a linear functional argument. In this paper, we introduce a numerical method based on the ... -
Spectrophotochemical and electrochemical characterization of perylene derivatives adsorbed on nanoporous metaloxide films
(Edp Sciences S A, 2007)Electrochemistry of perylene imide and anhydride derivatives adsorbed on semiconductor TiO2 (NT) and insulator Al2O3 (NA) metal oxide films were presented. Adsorption rates on metal oxide surface are observed to be strongly ... -
Exploratory study of small timber trusses constructed with through-bolt and cross-pipe heel connectors
(Forest Products Soc, 2007)Throughout the world, there is a need for simple, strong, yet inexpensive connectors that can be used to fabricate trusses from natural small-diameter tree stems as well as squared stems without extensive premachining of ... -
The effects of calcium sulphate on growth, membrane stability and nutrient uptake of tomato plants grown under salt stress
(Pergamon-Elsevier Science Ltd, 2007)A pot experiment was carried out with tomato (Lycopersicon esculentum Mill.) cv. "Target F1" in a mixture of peat, perlite, and sand (1:1: 1) to investigate the effects of supplementary calcium sulphate on plants grown at ... -
A judicial outcome analysis of the Disability Discrimination Act: a windfall for employers?
(Routledge Journals, Taylor & Francis Ltd, 2007)November 2005 was the tenth anniversary of the passing of the Disability Discrimination Act (DDA). This study presents a judicial outcome analysis regarding employment using decisions taken and made public by appellate ... -
New perylene derivative dyes for dye-sensitized solar cells
(Elsevier, 2007)We have studied the influence of the spacer alkyl chain length of perylenemonoimide (PMI) dyes on the device performance in dye-sensitized solar cells (DSSCs). We observed that the dyes with longer and brunched alkyl chains ... -
An engineered second disulfide bond restricts lymphotactin/XCL1 to a chemokine-like conformation with XCR1 agonist activity
(Amer Chemical Soc, 2007)Chemokines adopt a conserved tertiary structure stabilized by two disulfide bridges and direct the migration of leukocytes. Lymphotactin (Ltn) is a unique chemokine in that it contains only one disulfide and exhibits ... -
Tourist harassment - A marketing perspective
(Pergamon-Elsevier Science Ltd, 2007)Consumer services research contains few empirical studies of harassment involving tourists. Previous studies are largely in general typological terms. Relatively little is known about the effects of harassment on tourist ... -
Effects of subacute treatment of ethylene glycol on serum marker enzymes and erythrocyte and tissue antioxidant defense systems and lipid peroxidation in rats
(Elsevier Ireland Ltd, 2007)The present study was aimed to investigate the effects of ethylene glycol (EG) on serum marker enzymes, antioxidant defense systems and lipid peroxidation concentration (malondialdehyde = MDA) in various tissues of rats ... -
Squark pair production in the MSSM with explicit CP violation
(Amer Physical Soc, 2007)We analyze effects of the CP-odd soft phases in the MSSM on the pair productions of colored superpartners in pp collisions at the LHC energies. We find that, among all pair-production processes, those of the scalar quarks ... -
