On Markov Moment Problem and Mazur-Orlicz Theorem

Octav Olteanu, Janina Mihaela Mihaila
Applications of the generalization of Mazur-Orlicz theorem to concrete spaces are proved. Suitable moment problems are solved, as applications of extension theorems of linear operators with a convex and a concave constraint. In particular, a relationship between Mazur-Orlicz theorem and Markov moment problem is partially illustrated. In the end of this work, an application to the multidimensional Markov moment problem of an earlie

On Certain Subclass of Analytic Functions Based on Convolution of Ruscheweyh and Generalized Salagean Differential Operator

Ajai P. Terwase
In this paper, we obtain certain properties of an operator defined by the convolution between Ruscheweyh and Salagean differential operator; coefficient inequality, extreme point growth and distortion among other properties are investigated.

3D Matrix Ring with a “Common” Multiplication

Orgest ZAKA
In this article, starting from geometrical considerations, he was born with the idea of 3D matrices, which have developed in this article. A problem here was the definition of multiplication, which we have given in analogy with the usual 2D matrices. The goal here is 3D matrices to be a generalization of 2D matrices. Work initially we started with 3×3×3 matrix, and then we extended to m×n×matrices. In this article, we give the meaning of 3D matrices. We als...

On the Imaginary Geometry

Abdullah Kurudirek, Huseyin Akca
In this paper, we have aimed at showing the available set of points of Lobachevsky axiom by the help of Euclidean plane (As it is known, an Euclidean plane, which is a flat surface with no thickness, extends forever to all directions.), especially on behalf of broadening the horizons in geo- metry education of high school students.

On the Concept of Circle and Angle in Galilean Plane

Abdullah Kurudirek, Hüseyin Akca
In this paper, we try to show what some basic definitions like angle and circle which are taught in Euclidean plane at secondary and high schools, mean in Galilean plane. Furthermore we try and target to introduce the results of angle and circle concepts, comparing different situations of the same definitions in Galilean and Euclidean planes.

Effect of Acid, Base and Time on Different Brands of Glimepiride

Safila Naveed, Hina Qamar, Wardha Jawaid, Urooj Bokhari

The objective of this study is to develop the degradation studies of different brands of glimepiride available in market. Forced degradation is a powerful tool used routinely in pharmaceutical development in order to develop stability-indicating methods that lead to quality stability data and to understand the degradation pathways of the drug substances and drugs. Glimepiride is a medium- to long-acting sulfonylurea antidiabetic drug as it is the most prescribed oral antih

On Convexity and Approximating the Perimeter of an Ellipse

Octav Olteanu
In the first part of this work, a convex partition of a compact subset is constructed. Minimum-length surrounding curve and minimum-area surrounding surfaces for a compact set are constructed too. In the second part, one writes the perimeter of an ellipse as the sum of an alternate series. On the other hand, we deduce related “sandwich” inequalities for the perimeter, involving Jensen’s inequality and logarithmic function respectively. We discuss the values of the ordinate of the gravity center ...
