Acceptor formation in Mg-doped, indium-rich GaxIn1-xN: evidence for p-type conductivity
(Springer, 2012)We report on the Mg-doped, indium-rich Ga (x) In1-x N (x < 30). In the undoped material, the intrinsic electron density is very high and as a result there is no detectable photoconductivity (PC) signal within the range of ... -
Adsorption kinetics and isotherm parameters of naphthalene onto natural- and chemically modified bentonite from aqueous solutions
(Springer, 2013)Polycyclic aromatic hydrocarbons (PAHs) have widely been studied and a special concern because of their mutagenic and carcinogenic activities. In this study, natural- and chemically modified-bentonite were characterized ... -
Adsorption of Reactive Black 5 onto quaternized 2-dimethylaminoethyl methacrylate based polymer/clay nanocomposites
(Springer, 2016)[2-(Methacryloyloxy)ethyl]dimethylhexadecylammonium bromide (DMAC16) was synthesized by means of quaternization of 2-dimethylaminoethyl methacrylate with 1-bromohexadecane. Poly(DMAC16) and poly(DMAC16)-bentonite nanocomposites ... -
Amycolatopsis cappadoca sp nov., isolated from soil
(Springer, 2018)An Amycolatopsis strain, designated AG28(T), isolated from a soil sample collected from AcA +/- gol, Kapadokya, Turkey, was examined using a polyphasic taxonomic approach. Phylogenetic analysis based on an almost-complete ... -
Analysis of airborne pollen grains in Bilecik, Turkey
(Springer, 2009)In this study, pollen grains in the atmosphere of Bilecik were studied for a continuous period of 2 years (2005 and 2006) by using Durham sampler. During this period, pollen grains belonging to 46 taxa were recorded, 26 ... -
Analysis of international debt problem using artificial neural networks and statistical methods
(Springer, 2010)It is known from the scientific researches that artificial neural networks are alternatives of statistical methods such as regression analysis and classification in recent years. Since multi-layer backpropagation neural ... -
Ancient genetic bottleneck and Plio-Pleistocene climatic changes imprinted the phylobiogeography of European Black Pine populations
(Springer, 2017)The historical changes in European Black Pine population size across the whole natural distribution in Europe and Asia Minor were analyzed facing the Plio-Pleistocene climatic fluctuations. Thirteen chloroplast SSRs and ... -
The anti-angiogenic potential of (+/-) gossypol in comparison to suramin
(Springer, 2018)Cotton, a staple fiber that grows around the seeds of the cotton plants (Gossypium), is produced throughout the world, and its by products, such as cotton fibers, cotton-seed oil, and cottonseed proteins, have a variety ... -
Anti-breast cancer and anti-angiogenic potential of a lichen-derived small-molecule: barbatolic acid
(Springer, 2018)Natural products have been used for centuries as the most potent remedies to cure many diseases including cancer diseases. Angiogenesis is defined as the formation of new capillaries from existing vessels and plays a key ... -
Assessment of in vitro cytotoxic and genotoxic activities of some trimethoprim conjugates
(Springer, 2018)Trimethoprim, a commonly used antibacterial agent, is widely applied in the treatment of variety of infections in human. A few studies have demonstrated an extensive exposure of man to antibiotics, but there is still a ... -
Asymmetric control limits for small samples
(Springer, 2009)When designing control charts, it is usually assumed that the measurement in the subgroups are normally distributed. The assumption of normality implies that the control limits for a chart for sample averages will be ... -
The Bakry-Emery Ricci tensor and its applications to some compactness theorems
(Springer, 2012)Let (M, g) be a complete and connected Riemannian manifold of dimension n. By using the Bakry-Emery Ricci curvature tensor on M, we prove two theorems which correspond to the Myers compactness theorem. -
Barrier lowering effect and dark current characteristics in asymmetric GaAs/AlGaAs multi quantum well structure
(Springer, 2011)In this study, we investigate dark current voltage characteristics of GaAs/AlGaAs staircase-like asymmetric multiquantum well structure at various temperatures experimentally. The activation energy is calculated by using ... -
Biological efficacy of Trichoderma harzianum isolate to control some fungal pathogens of wheat (Triticum aestivum) in Turkey
(Springer, 2007)Gaeumannomyces graminis var. tritici, Fusarium culmorum and F. moniliforme are highly important and widespread pathogens of wheat in Turkey. Trichoderma isolates have been used as biocontrol agents to protect plants against ... -
Biomarkers of ecotoxicological oxidative stress in an urban environment: using evergreen plant in industrial areas
(Springer, 2015)Plants react to air pollution by increased production of reactive oxygene species and oxidative stress, which triggers multiple defense mechanisms. In this study, some parameters that serve as biomarkers for antioxidative ... -
The Bochner technique and modification of the Ricci tensor
(Springer, 2009)In the well-known vanishing theorems of Bochner, the assumptions Ric a parts per thousand yen 0 and Ric a parts per thousand currency sign 0 are modified by using Hessian and Laplacian of a smooth positive function such ... -
Brown-Robinson method for interval matrix games
(Springer, 2011)In this paper, two-person interval matrix games are considered, and by means of acceptability index, Brown-Robinson method to find a mixed-strategy equilibrium is adapted to interval matrix games. Numerical examples are ... -
