Thermal regime and tectonic pattern of the central-northern Apennines

Pojam stres se upotrebljava kako bi se opisao osjećaj straha, nezadovoljstva, nemira i nelagode. To je složen proces između određene osobe i njenog života. Stres koji studenti doživljavaju na fakultetu je jedan vrlo značajan čimbenik koji može nepovoljno utjecati na svakodnevno funkcioniranje studenata i kvalitetu studiranja. Cilj istraživanja je utvrditi razinu stresa studenata prve i treće godine stručnog studija te usporediti razinu stresa između studenata prve i treće godine studija. Hipoteza istraživanja zasniva se na pretpostavci da je razina stresa kod studenata prve godine stručnog studija veća od studenata treće godine stručnog studija. Ispitanici su studenti prve i treće godine stručnog studija sestrinstva na Visokoj tehničkoj školi u Bjelovaru. U istraživanju je korišten socio – demografski upitnik koji je konstruiran za potrebe ovog istraživanja, a koji obuhvaća podatke o spolu i dobi. Podaci su obrađeni deskriptivnim statističkim metodama

Thermal log analysis for recognition of ground surface temperature change and water movements

International audienceA joint analysis of surface air temperature series recorded at meteorological stations and temperature-depth profiles logged in near-by boreholes was performed to estimate conditions existing prior to the beginning of the instrumental record in central-northern Italy. The adopted method considers conductive and advective heat transport in a horizontally layered medium and provides simultaneous estimates of the pre-observational temperatures and the Darcy velocities. The reconstruction of the ground surface temperature history using an inversion method was performed for boreholes where hydrological disturbances to measured temperature logs were proved to be negligible. Both methods revealed generally coherent climatic changes in the whole investigated area. Climatic conditions were generally warm and comparable with the reference period 1960?1990. The absence of the Little Ice Age in the middle ages seems to be a generic feature of the climate in central-northern Italy. Climate change of the 19th century was generally insignificant with well balanced periods of cold and warmth. The investigated area became significantly colder only at the end of the 19th century. Cooling culminated around 1950 when it was replaced by rapid warming. Recent warming was not inferred only for one of the investigated holes. This discrepancy can be attributed to local environmental conditions

New results on focusing of gamma-rays with Laue lenses

We report on new results on the development activity of broad band Laue lenses for hard X-/gamma-ray astronomy (70/100-600 keV). After the development of a first prototype, whose performance was presented at the SPIE conference on Astronomical Telescopes held last year in Marseille (Frontera et al. 2008), we have improved the lens assembling technology. We present the development status of the new lens prototype that is on the way to be assembled.Comment: 8 pages, 11 figures, to be Published in SPIE Proceedings, vol.7437-19, 200
