A high sensitive CMOS Micro-electro-mechanical rectangular capacitive pressure sensor in SiGeMEMS process (Silicon Germanium Micro-electro-mechanical System process) is designed and analyzed. Polycrystalline Silicon Germanium (Poly-SiGe) having low fatigue and high strength is effectively used as the sensor diaphragm material to achieve better reliability. The designed perforated diaphragm clam...

This paper presents the results of measurements of aerosol optical properties which were made between 2006 and 2008 within the framework of various international projects in different locations such as Spitsbergen, northern Norway and Crete. The investigations were made under different baric topography conditions and in various seasons of the year which facilitated the investigations of spatial...

Sleep and the hypothalamic-pituitary-adrenocortical (HPA) activity are two biological processes that play a vital role for physical and mental health as well as general well-being. The aim of this cumulative dissertation containing three studies is to complement and extend existing research on the role of sleep and the HPA activity for psychosocial adjustment during childhood and adolescence, a...

Stratospheric and middle-mesospheric ozone profiles above Bern, Switzerland (46.95 N, 7.44 E; 577 m) have been continually measured by the GROMOS (GROundbased Millimeter-wave Ozone Spectrometer) microwave radiometer since 1994. GROMOS is part of the Network for the Detection of Atmospheric Composition Change (NDACC). A new version of the ozone profile retrievals has been developed with the aim ...

A cut-off low is a closed with value of geopotential height at the upper atmospheric levels that has been fully detached (cut-off) from westerly flow and move independently. causes extreme rainfall events in mid-latitudes regions. The main aim this paper to investigate 500 hPa over Iraq synoptic point view behavior hPa. To examine association across Iraq, two case studies heavy different times ...

Maternal social stress during late pregnancy programs hypothalamo-pituitary-adrenal (HPA) axis hyper-responsiveness to stressors, such that adult prenatally stressed (PNS) offspring display exaggerated HPA axis responses to a physical stressor (systemic interleukin-1β; IL-1β) in adulthood, compared with controls. IL-1β acts via a noradrenergic relay from the nucleus tractus solitarii (NTS) to c...
