This thesis is concerned with universal differential operator modules of order n. Let R be a commutative k-algebra where k is an algebraically closed field of characteristic zero. Let m and n be positive integers such that ...

Nitrosoamines are not added to the compounds directly, their formation follows some consecutive reactions or chemical interactions. They can also be formed in living organisms as in vivo. Dimethylnitrosoamine (NDMA) is ...

Let M ve N be R-modules. Recent works have shown that some structures of the ring and module theory can be carried out in the context of Hom(M,N), the abelian group of all morphisms of M into N. The aim of this thesis is ...

This work is devoted to the existence and uniqueness of the solution of 3. typeinitial-boundary value problem for nonlinear diffusion type equation and also devotedto the behavior of solution. In the first chapter, our ...

In this dissertation, the study of long-time behavior and solvability of the reaction-diffusion equation, which has a polynomial growth nonlinearity of arbitrary order, with Robin boundary condition on the bounded domain ...

A knot that is everywhere tangent to the contact planes is called a Legendrian knot. There are two types of Legendrian knots in overtwisted contact 3-manifolds: Loose and non-loose Legendrian knots. In the thesis, we study ...

In this thesis, we consider pants decomposition of orientable Riemann surfaces. First, using the notion symplectic chain complex, we prove a new formula Reidemeister torsion of a pair of pants. By using this, we establish ...

This study was carried out in an 820 ha area in Kızılırmak Delta, in 2011-2013. This study aimed to determine the nest success and territory size of the red-backed shrike (Lanius collurio) breeding in Kızılırmak Delta. ...

Analysis of morhpological traits of living organisms has always created a great interest in biological sciences. In addition to the use of physical traits in systematics studies in botany or zoology, physical traits such ...

In this study, the mutagenic potentials of 15 newly synthesized 2- substituted benzothiazole derivatives those are thougt to have chemotheropatic effect, were investigated by using short time bacterial mutagenicity test ...
