(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 ... -
3,5-Diamino İzoksazol Sübstitüye Triarilmetan Bileşiklerinin Sentezi
(Fen Bilimleri Enstitüsü, 2023)Isoxazoles are five-membered heterocyclic aromatic compounds. The given examples in the literature show that their synthesis and reactions have a wide importance. The reason for this is that the isoxazole compounds find ... -
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 ... -
5-Florourasil Yüklü PLGA Nanopartiküllerinin Toroidal Mikroakışkan Sistemler ile Üretimi ve Proses Değişkenlerinin Deney Tasarımı ile Optimizasyonu
(Fen Bilimleri Enstitüsü, 2024-09-09)In recent decades, microfluidics has presented new opportunities for the production of nanoparticles (NPs). However, microfluidic devices that produce NPs at laboratory scale require more advanced technologies to enable ... -
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)
