Base solids

An improved six-node triangular finite element based on a twice-interpolation strategy (TIS) for accurately modeling singular stress fields near crack tips of two-dimensional (2D) cracks in solids is presented. In contrast to the traditional approaches, the approximation functions constructed based on the TIS involve both nodal values and averaged nodal gradients.

The thesis is performed theoretically and experimentally. The theoretical studies on the dynamics of the single short pulse emission using transient cavity method and narrow linewidth and tunable wavelength generation using Littrow grating configuration were performed. On the other hand, the experimental investigations were carried out Experimental research was carried out based on the optimal results obtained by the theoretical studies.

A degree that once was seen as the safeguard for unemployment now become somewhat irrelevant. A higher education degree cannot give sufficient tools for an entire career, but it can form the basis for effective lifelong learning. The importance of higher education will increase when lifelong learning, including its solid base, are emphasised in the future.

Morphological and cultural variability of S. rolfsii infecting tomato were studied on different solid and liquid media based on radial growth, topography, sclerotial number, diameter of sclerotia, test weight of sclerotial bodies and dry mycelial weight. Significant variability with reference to mycelial and sclerotial characters was observed on different media. This investigation revealed that the maximum mycelial growth was observed in Potato Dextrose Agar (9 cm) and more test weight (262 mg) of sclerotial bodies was recorded in Sabouraud’s dextrose agar.

This paper reports on the study for determination of Methamphetamine in urine samples by GC-MS method using Solid Phase E.xtraction (SPE). The aim of the study was investigation on the GC-MS method for determination of Methamphetamine in urine samples. The method is based on the extraction of Methamphetamine by using of Solid Phase Extraction technique with C18 and its determination by GC-MS. The method was then successfully applied for the determination of Methamphetamine in real samples.

The basic properties of zeolites were studied by using quantum-chemical calculations. The obtained results have demonstrated that the basicity of zeolites in the forms of alkali cations (Li, Na or K) is increased with increasing cation radius. While the Si/Al ratio in the framework increases, the basicity of zeolites decreases. The application of adsorption method using acidic gases (CO2) for determining basicity may be suitable for solid bases without exhanged ion, but not for zeolites.
