Background: Possibilities of detecting oxygen - both in its free form, as gas in the lungs, and in its bound form, as oxygenated hemoglobin - have been explored in this thesis. Perfusion and oxygenation of vital organs (e.g., heart, brain and kidneys) may be severely compromised in critical illness or major trauma, which is why blood is rapidly diverted to those organs to improve chances of surviv

Given a harmonic vector field u on a bounded domain we call the set on which u enters the domain entrant boundary and the set on which u exits the domain emergent boundary. In the first part of this thesis we ask the question of whether it is possible to have interior stagnation points and connected entrant and emergent boundaries. The answer in two dimensions for a domain homeomorphic to a disc i

The present work reports on testicular hormone-sensitive lipase (HSL), the biological significance of which has been documented in male fertility. The HSL protein levels and enzymatic activity were measured, respectively, by densitometry of immunoreactive bands in Western blots, performed with antibodies against recombinant rat HSL, and by spectrophotometry in seminiferous tubules (STf) and inters

The role of cholesterol differs in the two compartments of the testis. In the interstitial tissue, cholesterol is necessary for the synthesis of testosterone, whereas in the seminiferous tubules, membrane cholesterol content in developing germ cells will influence the gametes' fertility. Here we evaluate the hormone-sensitive lipase (HSL) modulation of the cholesterol metabolism in each compartmen

The Common Agricultural Policy is one of the most important policies within the European Union. However, the support from CAP have had some unexpected consequences for the environment. Major changes were made in 2003 regarding the way payments were given to farmers, in order to reduce the environmental impact of agricultural production. The support was made decoupled, which basically meant a great

The goal of this study is to investigate the applicability of asymmetrical flow field-flow fractionation (AsFlFFF)–multi angle laser light scattering (MALLS), and to develop a method for analysis of cationic potato amylopectin (CPAP) having ultrahigh molecular mass (UHMr). Use of the aqueous carrier having low salt content (3 mM NaN3) resulted in a distortion in AsFlFFF fractograms of CPAP with a

Emotional AI systems decode human emotions through facial micro-expressions, vocal patterns, and physiological data. While the EU Artificial Intelligence Act prohibits emotion recognition in workplaces and educational institutions, broad security exemptions permit deployment in military, defense, national security, and law enforcement contexts. This article demonstrates how these exemptions create
