Glucocorticoids (GCs) are widely prescribed as anti-inflammatory drugs due to their well-established immunosuppressive effects.

The major aim is to determine the psychophysiological responses to stress and stress-management interventions and to examine the role of stress and stress-related psychophysiological mechanisms (e.g., cognitions, behaviors, and physiological stress responses) in both healthy and medical populations.

This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.

1. What is the exact role of PIN proteins in PAT? 2. How is PIN polarity established, and how is it modulated by AGC kinase-mediated phosphorylation? 3. What is the role of the AGC kinase, as modulators of PAT, in translating environmental signals, such as gravity, light or mechanical stress, to plant…

Seasonal influenza vaccines provide protection against matching influenza A virus (IAV) strains mainly through the induction of neutralizing serum IgG antibodies. However, these antibodies fail to confer a protective effect against mismatched IAV. This lack of efficacy against heterologous influenza…

On the 14th December 2016, Steven L. Schwarcz, Stanley A. Star Professor of Law and Business at Duke University School of Law gave the thirteenth Hazelhoff Guest Lecture.

Emerging from the first wave relatively unscarred to an increase in infections. This research analyses the response from the Bulgarian government to Covid-19.

Promotor: Prof.dr. W.J.G.M. Peijnenburg, Co-promotor: Dr. ing. M.G. Vijver

This article provides a behavioral perspective that examines responsibility attribution to the national government (upward) and policy implementers (downward) as a function of performance relative to decision-makers' aspiration levels. The study proposes that perceived accountability increases the propensity…
