12. Modulation of serous salivary gland function by the sympathetic nervous system : a biochemical and ultrastructural study with special reference to β-adrenoceptor subtypes
Abstract : The aim of the present investigation was to study the influence of the sympathetic nervous system and of various adrenoceptor agents on enzyme secretion and morphology in rat parotid and guinea-pig submandibular glands. Biochemical methods were combined with electron microscopical techniques. READ MORE

13. Development of diode laser-based absorption and dispersion spectroscopic techniques for sensitive and selective detection of gaseous species and temperature
Abstract : The main aim of this thesis has been to contribute to the ongoing work with development of new diode-laser-based spectroscopic techniques and methodologies for sensitive detection of molecules in gas phase. The techniques under scrutiny are tunable diode laser absorption spectrometry (TDLAS) and Faraday modulation spectrometry (FAMOS). READ MORE

14. Domain engineering in KTiOPO4
Abstract : Ferroelectric crystals are commonly used in nonlinear optics for frequency conversion of laser radiation. The quasi-phase matching (QPM) approach uses a periodically modulated nonlinearity that can be achieved by periodically inverting domains in ferroelectric crystals and allows versatile and efficient frequency conversion in the whole transparency region of the material.

15. Diffractive Optics Design
Abstract : Diffractive optical elements (kinoforms) change the way light propagates, and can perform very complex tasks. They can split an incident beam into any number of outgoing, and possibly focused, beams (fan-out). READ MORE
