David and Goliath: Aspects of Air Warfare in the China-Taiwan Confrontation

The prospect of a Chinese invasion of Taiwan and the impact it would have on the region has been a subject of concern for many years. The aim of this thesis is to analyze the potential outcome of air warfare in such an event, focusing on changes in Chinese and Taiwanese military capabilities over time. Drawing on previous RAND Corporation research published over the past two decades, this thesis examined two aspects of a potential Chinese invasion, the possibility of a disarming strike against Taiwanese air defenses and air bases, and the possible outcome of air warfare. To accomplish this, the critical variables from previous studies were examined and the development of their values was assessed through a mixture of quantitative and qualitative analysis. The thesis finds that China currently has the upper hand in military capabilities, making it unlikely that Taiwan could sustain a full-scale air war without U.S. support. The study also discusses possible future developments in the contest for air superiority over Taiwan in the next decade and offers policy implications for Taiwan to maintain close ties with its allies and invest in its military capabilities, especially air defense

Cílem této práce je analyzovat potenciální výsledek letecké války v případě čínské invaze se zaměřením na změny čínských a tchajwanských vojenských schopností v průběhu času. Na základě předchozích výzkumů společnosti RAND Corporation publikovaných v posledních dvou desetiletích tato práce zkoumá dva aspekty potenciální čínské invaze, a to možnost odzbrojujícího úderu proti tchajwanské protivzdušné obraně a leteckým základnám a možný výsledek letecké války. Za tímto účelem byly zkoumány kritické proměnné z předchozích studií a vývoj jejich hodnot byl posuzován prostřednictvím kombinace kvantitativní a kvalitativní analýzy. Práce dochází k závěru, že Čína v současné době disponuje převahou ve vojenských schopnostech, takže je nepravděpodobné, že by Tchaj-wan dokázal obstát v plnohodnotné letecké válce bez podpory USA. Studie se rovněž zabývá možným budoucím vývojem v soupeření o vzdušnou převahu nad Tchaj-wanem v příštím desetiletí a nabízí možné politické implikace pro Tchaj-wan, aby udržoval úzké vazby se svými spojenci a investoval do svých vojenských schopností, zejména do protivzdušné obrany.Katedra politologieDepartment of Political ScienceFaculty of Social SciencesFakulta sociálních vě

Development and validation of a reversed-phase liquid chromatographic method for analysis of demeclocycline and related impurities

A simple, robust, and rapid reversedphase high-performance liquid chromatographic method for the analysis of demeclocycline and its impurities is described. Chromatographic separations were achieved on a Symmetry Shield RP8 (75 mm × 4.6 mm, 3.5 μm) column kept at 40°C. The mobile phase was a gradient mixture of acetonitrile, 0.06 M sodium edetate (pH 7.5), 0.06 M tetrapropylammonium hydrogen sulphate (pH 7.5) and water, A (2:35:35:28 v/v/v/v) and B (30:35:35:0 v/v/v/v) pumped at a flow rate of 1 mL/min. UV detection was performed at 280 nm. The developed method was validated according to the ICH guidelines for specificity, limit of detection, limit of quantification, linearity, precision, and robustness. An experimental design was applied for robustness study. Results show that the peak shape, chromatographic resolution between the impurities, and the total analysis time are satisfactory and better than previous methods. The method has been applied for the analysis of commercial demeclocycline bulk samples available on the market.status: publishe
