Evolution Of Karst In The Lower Part Of Crna Reka River Basin

It reveals the nonlinear and nonequilibrium features, discusses the corresponding flow and heat transfer mechanisms, and ultimately establishes an analytical engineering theory framework for hypersonic rarefied and chemical nonequilibrium flows.The original analytical findings presented are not only of great academic significance, but also hold considerable potential for applications in engineering practice. Theoretical Modelling of Aeroheating on Sharpened Noses under Rarefied Gas Effects and Nonequilibrium Real Gas Effects employs a theoretical modeling method to study hypersonic flows and aeroheating on sharpened noses under rarefied gas effects and nonequilibrium real gas effects that are beyond the scope of traditional fluid mechanics.

.The author also applies modern methods of multiscale analysis to extract novel bounds on the transport properties of these many body systems.

 In this thesis two variants of the fast variable elimination method are developed. The relative simplicity of the techniques makes them ideal for applying to problems featuring demographic stochasticity, for experts and non-experts alike.

In general, the systems studied in the corresponding experiments are exposed to strong thermal fluctuations and thus the relevant energetic variables such as work and heat become stochastic. Non-equilibrium Energy Transformation Processes.This thesis addresses challenging theoretical problems in this active field of current research: 1) Exact analytical solutions of work and heat distributions for isothermal non-equilibrium processes in suitable models are obtained; 2) Corresponding solutions for cyclic processes involving two different heat reservoirs are found; 3) Optimization of periodic driving protocols for such cyclic processes with respect to maximal output power, efficiency and minimal power fluctuations is studied.

, the maintenance mechanism of the solar differential rotation in the near-surface shear layer.

This thesis introduces a series of novel, non-conjugated polyarylether hosts that are not subject to the triplet-energy limitations of traditional conjugated polymer hosts.

The Chemistry of Zirconacycles and 2,6-Diazasemibullvalenes In the first part, the author presents the development of multi-component cyclization of a zirconacyclobutene-silacyclobutene fused compound, nitriles and unsaturated compounds.

. It tackles the extent and complexity of both epigenic and hypogenic karst development, based on morphological analyses of caves, combined with analyses and datations of cave sediments and their correlation to regional geological and geomorphological evolution.

The isolation and characterization of the key three-fused-ring Zr/Si-containing intermediates are also described in detail. In the second part, the author demonstrates the synthesis and isolation of a series of 2,6-diazasemibullvalenes (NSBVs) from the reaction of 1,4-dilithio-1,3-dienes and nitriles, highlighting the significant progress made for the first time in this work: (1) determination of X-ray crystal structure of a substituted 2,6-diazasemibullvalene; (2) measurement of the activation barrier of its rapid intramolecular aza-Cope rearrangement in solution; (3) exploration of several reaction types of NSBV with diverse ring-expansion products and “bowl-shape” or “cage-shape” N-containing polycyclic skeletons; (4) demonstration of the localized structure as the predominant form and the homoaromatic delocalized structure as a minor component in the equilibrium using theoretical analysis. These reactions provide synthetically useful methodology for various N-heterocycles such as 3-acyl pyrrole, pyrrolo[3,2-d]pyridazine and dihydropyrroloazepine, which are all difficult to synthesize by other means.

Evolution of Karst in the Lower Part of Crna Reka River Basin Epigenic speleogenesis is strongly controlled by base level oscillations, with also examples of deep phreatic (now fossil) caves connected to regional base level rise, and per-ascensum speleogenesis..   Another important finding is the constraining of the timing of Mariovo Lake draining in the Pleistocene, an important event in order to understand the geomorphological evolution in Macedonia, as it led to the onset of fluvial development and incision of valleys, shaping most of the present morphology. It tackles the extent and complexity of both epigenic and hypogenic karst development, based on morphological analyses of caves, combined with analyses and datations of cave sediments and their correlation to regional geological and geomorphological evolution.
