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 ... -
An Efficient Water-Mediated Synthetic Route For The Alkylation of Heteroarenes
(Scientific Technical Research Council Turkey-Tubitak, 2018)An efficient synthetic route has been described for the alkylation of 1H-indole, 1H-benzimidazole, and 1H-benzotriazole. This approach features the alkylation of heteroaromatics through in situ generated enones from ketonic ... -
Comparative Study Of Microwave-Assisted And Conventional Synthesis Of Ibuprofen-Based Acyl Hydrazone Derivatives
(Scientific Technical Research Council Turkey-Tubitak, 2013)A series of potential biological active acyl hydrazone derivatives containing ibuprofen moiety (compounds 4a-4p) was synthesized by the condensation of ibuprofen hydrazone with aromatic aldehydes using conventional and ... -
Comparison Of Growth And Reproduction Of Mirror Carp And Scaled Carp Introduced Into Gelingullu Reservoir, Yozgat, Turkey
(Scientific Technical Research Council Turkey-Tubitak, 2013)Carp have been translocated and introduced outside of their natural range in many countries. In Turkey, mirror carp (a warmwater fish) has generally been introduced into man-made reservoirs for fishery management, regardless ... -
Effect of Sonic Treatment on The Permeation Performance of Cellulose Acetate Membranes Modified By N-Sio2
(Scientific Technical Research Council Turkey-Tubitak, 2015)Cellulose acetate (CA) membranes were modified by nano-silicon dioxide (n-SiO2), and they were exposed to ultrasonic waves at a frequency of 35 kHz. The effect of sonication on their water sorption tendency and permeation ... -
Evaluation Of Spectrum Of 2-Periodic Tridiagonal-Sylvester Matrix
(Scientific Technical Research Council Turkey-Tubitak, 2016)The Sylvester matrix was first defined by JJ Sylvester. Some authors have studied the relationships between certain orthogonal polynomials and the determinant of the Sylvester matrix. Chu studied a generalization of the ... -
Facile Synthesis Of Heteroaryl Substituted Gamma-Lactams From Nitrovinyl Arenes
(Scientific Technical Research Council Turkey-Tubitak, 2018)Aliphatic nitroalkanes with different functional groups were synthesized from the Michael addition reactions of active methylene compounds 2 and nitrovinyl arenes 1 in high yields. The synthesized Michael adducts were ... -
Immobilized Metal Ion Affinity Nanospheres For Alpha-Amylase Immobilization
(Scientific Technical Research Council Turkey-Tubitak, 2014)Immobilized metal chelate affinity chromatography (IMAC) support was practiced for alpha-amylase immobilization. Poly(hydroxyethylmethacrylate-methacryloylamidotryptophan)-Ni2+ [p(HEMA-MAT)-Ni2+] nanospheres, average ... -
Legendrian Torus Knots in Lens Spaces
(Scientific Technical Research Council Turkey-Tubitak, 2018)In this study, we first classify all topological torus knots lying on the Heegaard torus in lens spaces, and then we study Legendrian representatives of these knots. We classify oriented positive Legendrian torus knots in ... -
More On Sequential Order Of Compact Scattered Spaces
(Scientific Technical Research Council Turkey-Tubitak, 2018)The proper forcing axiom is shown to imply that a compact scattered sequential space with scattering height at most omega(1) must have sequential order at most omega. -
On The Monodromy Of Milnor Open Books
(Scientific Technical Research Council Turkey-Tubitak, 2018)We present some techniques that can be used to factorize the monodromy of certain Milnor open books. We also describe a class of Milnor open books for which we can explicitly express the monodromy as a product of Dehn twists. -
Some Rings For Which The Cosingular Submodule Of Every Module Is A Direct Summand
(Scientific Technical Research Council Turkey-Tubitak, 2014)The snbmodule (Z)overbar(M) = boolean AND{N vertical bar M/N is small in its injective hull} was introduced by Talebi and Vanaja in 2002. A ring R is said to have property (P) if (Z)overbar(M) is a direct summand of M for ... -
Structural Stability Analysis Of Solutions To The Initial Boundary Value Problem For A Nonlinear Strongly Damped Wave Equation
(Scientific Technical Research Council Turkey-Tubitak, 2016)In this paper the initial-boundary value problem for a nonlinear strongly damped wave equation is considered. We analyze the structural stability of solutions of the nonlinear strongly damped wave equation with coefficients ... -
The Generalized Reciprocal Super Catalan Matrix
(Scientific Technical Research Council Turkey-Tubitak, 2016)The reciprocal super Catalan matrix studied by Prodinger is further generalized, introducing two additional parameters. Explicit formulae are derived for the LU-decomposition and their inverses, as well as the Cholesky ... -
The Productively Lindelöf Property In The Remainders Of Topological Spaces
(Scientific Technical Research Council Turkey-Tubitak, 2018)A topological space X is called productively Lindelof if X x Y is Lindelof for every Lindelof space Y. We study with remainders and investigate topological spaces with productively Lindelof remainders.
