1-Dimensional Harnack Estimates
(Amer Inst Mathematical Sciences-Aims, 2016)Let u be a non-negative super-solution to a 1-dimensional singular parabolic equation of p-Laplacian type (1 < p < 2). If u is bounded below on a time-segment {y} x (0, T] by a positive number M, then it has a power like ... -

(Fen Bilimleri Enstitüsü, 2018-08)In this study, a new material for removal of metal ions from water samples was prepared by the chemically functionalization of silica gel. The organic ligand 5-chloro-2-(2'-hydroxyphenyl)benzothiazole (HPBT) was synthesized ... -
2-(5-Bromo-2-Piridilazo)-5-(Dietilamino) Fenol Katkılanmış Silika Partiküllerin Hazırlanması ve Zn(Iı) İyonlarının Adsorpsiyonu ve Kolorimetrik Tayini İçin Kullanımı
(Fen Bilimleri Enstitüsü, 2017)The aim of this work is to develop a ligand-modified mesoporous silica adsorbent for the removal and colorimetric determination of Zn(II) ions from water samples. In this study, mesoporous (monolithic) silica material ... -
2-Ethyl-6,6-EthylEnedisulfanediyl-7-MethoxyMethyl-1,2,3,4,5,6-HexaHydro-1,5-MethanoAzocino[4,3-B]Indol-3-One
(2010)The title compound, C20H24N2O2S2, consists of a tetracyclic ring system containing an azocino skeleton with ethyl, dithiolane and methoxymethyl groups as substituents. The benzene and five-membered rings are nearly ... -
(2S,5R)-2-Isopropyl-5-Methylcyclohexanone Hydrazones
(2019)Hydrazones were obtained in 76-78% yield via condensation of (2S,5R)-2-isopropyl-5-methylcyclohexanone with 4-R-phenoxyacetic acid hydrazides in the presence of a catalytic amount of glacial acetic acid. The structure of ... -
3-Aminopropiltrietoksisilan (APTS) ile Modifiye Polimer/Halloysit Nanotüplerinin Tasarımı, Sentezi ve Karakterizasyonu
(Fen Bilimleri Enstitüsü, 2017)In this thesis study; design, synthesis and characterization of poly (maleic anhydride-alt-acrylic acid) with biological activity and polymer/clay nanocomposites to be aimed. Poly (MA-alt-AA) was synthesized by complex ... -
6,6-[Ethylenebis(sulfanediyl)]-2-(2-methoxyethyl)-1,2,3,4,5,6-hexahydro-1,5-methano-1H-azocino[4,3-B]indol-3-one
(2010)The title compound, C19H22N2O2S2, consists of a tetracyclic ring system containing an azocine skeleton with methoxyethyl and dithiolane groups as substituents. The benzene and five-membered N-heterocyclic rings are ... -
A Bayesian Analysis For Identifying Dna Copy Number Variations Using A Compound Poisson Process
(2010)To study chromosomal aberrations that may lead to cancer formation or genetic diseases, the array-based Comparative Genomic Hybridization (aCGH) technique is often used for detecting DNA copy number variants (CNVs). Various ... -
A Category Approach to Relation Preserving Functions in Rough Set Theory
(Elsevier Science Inc, 2015)The category Rel whose objects are all pairs (U, r), where r is a relation on a universe U, and whose morphisms are relation-preserving mappings is a canonical example in category theory. One of the convenient categories ... -
A Coanalytic Menger Group That Is Not Sigma-Compact
(Scientific Technical Research Council Turkey-Tubitak, 2018)Under V = L we construct coanalytic topological subgroups of reals, demonstrating that even for definable groups of reals, selection principles may differ. -
A Combined First Principles TDDFT and Experimental Study on the Uv-Vis Spectra Properties of M(P-Nitrophenyl Azo Resorcinol)(3) Complexes (M: Fe, Cr)
(Scientific Technical Research Council Turkey-Tubitak, 2014)UV-Vis absorption data of p-nitrophenyl azo resorcinol (Magneson I) and its 2 Fe(III) and Cr(III) complexes were investigated both experimentally and theoretically. The geometries were optimized at BP86/TZVP level. The ... -

A Comparison of the Activities of Greek and Turkish Propolis Against Paenibacillus Larvae
(Int Bee Research Assoc, 2014)Propolis has a long history of use in traditional medicine dating back to at least 300 BC, and has been reported to have a broad spectrum of biological activities. Since most studies have to date focused on medical uses ... -
A Cross-Sectional Screening By Next-Generation Sequencing Reveals Rickettsia, Coxiella, Francisella, Borrelia, Babesia, Theileria And Hemolivia Species In Ticks From Anatolia
(2019)Background Ticks participate as arthropod vectors in the transmission of pathogenic microorganisms to humans. Several tick-borne infections have reemerged, along with newly described agents of unexplored pathogenicity. In ... -
A Data Science Study For Determining Food Quality: An Application To Wine
(2019)In this paper, wine quality is investigated based on physicochemical ingredients which include fixed acidity, volatile acidity, citric acid, residual sugar, chloride, free sulfur dioxide, total sulfur dioxide, density, pH, ... -
A Generalization of J - Quasipolar Rings
(Univ Miskolc Inst Math, 2017)In this paper we introduce a class of quasipolar rings which is a generalization of J-quasipolar rings. Let R be a ring with identity. An element a is an element of R is called delta-quasipolar if there exists p(2) = p is ... -
A Generalization of Projective Covers
(Academic Press Inc Elsevier Science, 2008)Let M be a left module over a ring R and I an ideal of R. We call (P, f) a projective I-cover of M if f is an epimorphism from P to M, P is projective, Ker f subset of I P, and whenever P = Ker f + X, then there exists a ... -
A Generalization Of Rickart Modules
(Belgian Mathematical Soc Triomphe, 2014)Let R be an arbitrary ring with identity and M a right R-module with S = End(R) (M). In this paper we introduce pi-Rickart modules as a generalization of Rickart modules. pi-Rickart modules are also a dual notion of dual ...
