Resveratrol reduces IL-6 and VEGF secretion from co-cultured A549 lung cancer cells and adipose-derived mesenchymal stem cells
(SAGE Publications LTD, 2016)Stem cell therapies are important treatment methodologies used in many areas of experimental or clinical medicine. In recent studies of cancer models, Mesenchymal stem cells (MSCs) suppressed the growth of cancer cells. ... -
Reusable Nanocopy Machine Particles for the Replication of DNA
(Wiley, 2015)As one of the most important components copying DNA molecules in the PCR system, Taq DNA polymerase has a high processivity, however, lower persistence when compared to other polymerases. Studies for the enhancement of ... -
Reverse atom transfer radical polymerization of stearyl methacrylate using 2,2'-azobisisobutyronitrile as the initiator
(2002)The living/controlled radical polymerization of stearyl methacrylate was carried out with a conventional radical initiator (2,2'-azobisisobutyronitrile) in N,N-dimethylformamide in the presence of a 2,2'-bipyridine complex ... -
Reversible and easy post-crosslinking method for developing a surface ion-imprinted hypercrosslinked monolith for specific Cd(II) ion removal from aqueous solutions
(Royal Soc Chemistry, 2016)In this study, a new surface imprinting technique for preparing a hypercrosslinked monolith to remove Cd(II) ions out from aqueous solutions was proposed. The monoliths were characterized by Fourier transform infrared ... -
A revision of the spider genus Raveniola (Araneae, Nemesiidae). I. Species from Western Asia
(Museum Natl Histoire Naturelle, 2018)The genus Raveniola Zonstein, 1987 is found to be represented in Western Asia by 16 species: male female R. adjarica sp. nov. (Georgia), male R. anadolu sp. nov. (Turkey), male R. arthuri Kunt & Yagmur, 2010 (Turkey), male ... -
Ridge-Type MML Estimator in the Linear Regression Model
(Springer International Publishing Ag, 2019)Ridge regression is widely used to deal with the multicollinearity problem. However, traditional ridge estimator (Hoerl and Kennard 1970) loses its efficiency in the presence of outliers, since it is obtained based on least ... -
Road Effect on the Breeding Success and Nest Characteristics of the Eurasian Magpie (Pica pica)
(Foundation Environmental Protection & Research-Fepr, 2012)It is known that roads have an ecological effect on wildlife, not only in negative but also in positive ways. Few studies provide information about the effect that roads have on bird population levels. In this study, we ... -
Road effect on the breeding success and nest characteristics of the eurasian magpie (Pica pica)
(2012)Yolun doğal yaşam üzerine hem olumlu hem de olumsuz yönde etkisi olduğu bilinmektedir. Bununla birlikte kuş populasyonları üzerine yolun etkisi ile ilgili olarak az sayıda çalışma olduğu görülmektedir. Bu çalışmada yolun ... -
ROBUST 2(k) FACTORIAL DESIGNS: NON-NORMAL SYMMETRIC DISTRIBUTIONS
(Isoss Publ, 2012)Senoglu (2005, 2007a) considered the estimation and hypothesis testing procedures for the 2(k) factorial designs when the error distributions are skew. They obtained the modified maximum likelihood (MML) estimators of the ... -
Robust 2k factorial designs: Non-normal symmetric distributions
(2012)Şenoglu (2005, 2007a) considered the estimation and hypothesis testing procedures for the 2k factorial designs when the error distributions are skew. They obtained the modified maximum likelihood (MML) estimators of the ... -
Robust Estimation for Parameters of the Extended Burr Type III Distribution
(Taylor & Francis Inc, 2015)We consider various robust estimators for the extended Burr Type III (EBIII) distribution for complete data with outliers. The considered robust estimators are M-estimators, least absolute deviations, Theil, Siegel's ... -
Robust Estimation With the Skew T(2) Distribution
(Isoss Publ, 2013)In this paper, a skew extension of the Student's t distribution with two degrees of freedom is used to model data sets that have skewness and heavy-tails. Its parameters are estimated using two different approaches based ... -
Robust estimation with the skew t2 distribution
(2013)In this paper, a skew extension of the Student's t distribution with two degrees of freedom is used to model data sets that have skewness and heavy-tails. Its parameters are estimated using two different approaches based ... -
Robust factorial ANCOVA with LTS error distributions
(Hacettepe University, Fac Sci, 2018)In this study, parameter estimation and hypotheses testing in the balanced factorial analysis of covariance (ANCOVA) model, when the distribution of error terms is long-tailed symmetric (LTS) are considered. The unknown ... -
Robust ridge and robust Liu estimator for regression based on the LTS estimator
(Taylor & Francis LTD, 2013)In the multiple linear regression analysis, the ridge regression estimator and the Liu estimator are often used to address multicollinearity. Besides multicollinearity, outliers are also a problem in the multiple linear ... -
The role of definition in students' understanding with particular reference to the concavity of a function
(2006)In this study, the effect of different definitions of concavity on students' understanding was investigated. Students enrolled in the calculus-II course in the science and engineering faculties in Anadolu University, Turkey ... -
The role of pH and boron doping on the characteristics of sol gel derived ZnO films
(Elsevier Science Sa, 2011)Undoped and boron doped ZnO films (nominal volume B/Zn ratio = 1%, 3% and 5%) were deposited onto glass substrates by the sol gel method using spin coating technique. Zinc acetate dihydrate (ZnAc), 2-methoxyethanol and ... -
Role of plants and vegetation structure on boron (B) removal process in constructed wetlands
