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 ... -
2-(2ʹ-Hidroksifenil)Benzotiyazol İle Modifiye Edilmiş Silika Partiküller Kullanılarak Metal İyonlarının Adsorpsiyonu
(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-PİRİDİLAZO)-5-(DİETİLAMİNO) FENOL KATKILANMIŞ SİLİKA PARTİKÜLLERİN HAZIRLANMASI VE Zn(II) İYONLARININ ADSORPSİYONU VE KOLORİMETRİK TAYİNİ İÇİN KULLANIMI
(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 ... -
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 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 ... -
