A containment scale-model test, performed at Sandia National Laboratories, was loaded by overpressurization and the first leak was concluded to be caused by tears in the steel liner found near the equipment hatch. These tears were located in the vicinity of the vertical fold in between the general curved part and the embossment (vertical bend line). A 3D finite element analysis of the region near
Popular Abstract in Swedish Åldrandet har traditionellt förknippats med en reduktion av emotionella reaktioner. Denna syn har nu börjat ifrågasättas, trots att de flesta tidigare studier visat en åldersrelaterad minskning av psykofysiologiska reaktioner på affektiva stimuli. Det första syftet med denna avhandling var att undersöka effekter av åldrande på subjektivt upplevande av och psykofysiologiIt has long been thought that aging is accompanied by an emotional flattening. Although a different view has started to emerge recently, studies investigating psychophysiological responses in reaction to affective stimuli so far have reported an age-related reduction of the affective response. One of the main goals of this thesis was to revisit this issue by examining subjective reports, phasic he
The flagellate Euglena gracilis shows rhythms in phototaxis and cell shape changes between oblong and round. Artificial UV-B radiation of 0.5 W m-2 caused a loss in phototaxis, but the peak of activity occurred at the same time as for control cells. The transition from round to oblong cell shape was slower after UV-B radiation, but the amplitude between the roundest and the most oblong cell shape
Klimatförändringarna gör att de skånska landekosystemen står inför stora förändringar, på grund av direkta klimateffekter samt som en följd av förändringar i skötsel och markanvändning som ett resultat av samhällets klimatanpassnings- och utsläppsminskningsåtgärder. Förlust av biologisk mångfald riskerar att öka ekosystemens sårbarhet gentemot klimatförändringarnas effekter. Förebyggande arbete
Popular Abstract in Swedish Utövandet av läkekonsten består till en del av rent medicinsk-tekniska insatser som grundas på vetenskap och beprövad erfarenhet. Dessa insatser äger rum inom ett omvårdnadssammanhang, och här anses den personliga relationen vara ytterst betydelsefull för patientens tillfrisknande. Patienter och vårdpersonal har specifika roller som ej är jämlika. Rollinnehåll och rollThe personalities and qualities of nursing personnel are considered to be of great importance for their interactions with patients and may also influence work satisfaction. The aim of the thesis was to explore the extent to which different personal qualities and personality factors, with a possible effect on motivation, professional conduct, and coping with anxiety, are represented in a group of a
Om Raoul Wallenberg och Oskar Schindler som hjältar i svensk, tysk, europeisk och amerikansk efterkrigstida bearbetning av andra världskriget och förintelsen.
This chapter presents the Development Policy Evaluation Model (DEVPEM), a new simulation model which captures four critical aspects of rural economies in developing countries: 1) the role of the household as both a producer and a consumer of food crops; 2) high transaction costs of participating in markets; 3) market linkages among heterogeneous rural producers and consumers; 4) the imperfect conv
The scope of this study is to compare John Philoponus and Cosmas Indicopleustes, two Christian individuals of different backgrounds and belonging to different fractions of the Church in the turbulent time for the Church in sixth century Alexandria. Any Christian is likely to feel the need to define how the tenets of his or her faith relate to contemporary science. As long as Christianity has exis
There are several ways to implement and work with the Balanced Scorecard (BSC). The company Ericsson Data AB was one of the pioneers in employing the BSC in Sweden. As early adopters, they were interested in obtaining an evaluation performed by external researchers. We were fortunate to have that opportunity. During the autumn of 1998, Majvor Karlsson and Ellen Sharma had full access to the develo
Echelle mode spectra obtained with the Goddard High Resolution Spectrograph onboard the Hubble Space Telescope have been used to determine the abundances of the heavy elements Pt, Au, and Hg in the chemically peculiar HgMn-type stars kappa Cancri and chi Lupi. The abundances were determined by fitting observed line profiles with synthetically generated spectra and are found to be enhanced relative
The outdoor environment is deteriorating in many tropical cities due to rapid urbanization. This leads to a number of problems related to health and well-being of humans and also negatively affects social and commercial outdoor activities. The creation of thermally comfortable microclimates in urban environments is therefore very important. This paper discusses the influence of street-canyon geome
Thiosphaera pantotropha is capable of aerobic heterotropic nitrification and both aerobic and anaerobic denitrification. These phenomena have been studied in acetate-limited aerobic and anaerobic continous cultures supplied with ammonia and nitrate. The internal reaction rates were defined, based on biochemical knowledge. The observable external conversion rates are related through a linear equati
In this article, we study the effects of the 2004 terrorist bombings in Madrid on ethnic segregation in Spain. Using large-scale Spanish register data consisting of information on 5.4 million international migration events on a monthly basis and 13.9 million intermunicipal migration events, of which 3.8 million events concern the foreign-born population’s internal migration within Spain, the analy
This paper examines the influence of land fragmentation on the value ofvegetables produced in the Skopje and Southeastern regions of the Republic ofMacedonia. The analysis uses models such as a Cobb-Douglas production function as well as a General Linear Model. The findings support a negative and statistically significant impact of land fragmentation on the productivity and profitability of vegeta
Sustainable management of water resources is imperative in the Western Balkan (WB) region, due to the seasonal, spatial and quality distribution of these resources. This paper analyzed water consumption and associated relationships between the economic sectors in Macedonia in 2005, based on input–output (IO) analysis. Using an environmentally extended IO framework, water consumption was investigat
