This thesis is concerned with theoretical studies of aqueous solutions and biomolecular systems. Part of the present work is to understand equilibrium solvent and solute properties, while the other part is to study processes that occur in these solutions. Three points were focused: (a) the study of structure and dynamics of 1M aqueous NaCl electrolyte solution at a molecular level, which revealed

Ischemic cerebrovascular disease (CVD) is usually a consequence of atherosclerosis and is the commonest cause of stroke. The identification of risk factors and outcome predictors and the initiation of preventive measures constitute the cornerstone of efforts to reduce the risk of stroke and improve outcome. The trend for long-term outcome after stroke and the predictors of this outcome were evalu

Research suggests that access to transport, communication, market, and social infrastructure is important for provision of health. Humanitarian organizations - realizing the importance of building local capacities - are allocating noticeable time and resources on the process. But, studies testing this relationship are scant. The purpose of this paper is to investigate the relation between transpor

We present time-resolved cross-correlation measurements of extreme ultraviolet (xuv) pulses generated as high-order harmonics of intense 35 fs pulses, using a short (12 fs) probe pulse. We modulate the ellipticity of the laser driving the generation process such that the polarization is linear for short times around the temporal peak of the pulse. Since harmonic generation is strongly suppressed f

This chapter exposes results of ethnographic work on a grassroots organisation offering training for sexual assistants for people with disabilities in Switzerland

Moths rely on the sense of smell (olfaction) as the main sensory input system in search for potential food sources and in selection of suitable females by males. Specific pheromones are fundamental to the reproductive isolation of species and consequently the olfactory system of moths has evolved to a high level of sensitivity and specificity. This thesis investigates differences between two phero

Joseph Roths klassiska essä "Judar på vandring" publicerades 1927 i förlagsserien ”Berättelser ur verkligheten”. Verkligheten är den östeuropeiska judendomen – de kringvandrande handlarna, fromheten, festerna, misären, drömmarna, de öden som väntade de miljoner som begav sig mot Amerika, undan progromerna i öst och senare nationalsocialismen. Roth förenar akribiska skildringar med svepande omdömen

In this paper, results from a perception experiment on perceived prosodic boundary strength in spontaneous speech are presented. The analysis of the listeners’ responses reveals a good agreement in rating the strength of prosodic phrase boundaries on a visual analogue scale (VAS), and a strong correlation between perceived boundary strength and pause duration.

Gestures—or bodily “actions that have the feature of manifest deliberate expressiveness” (Kendon, 2004, p. 15)—are an integral part of how we communicate.

Boken beskriver mycket översiktligt hur ett hus kommer till och vilka komponenter som ingår i byggnaden. Några djupare byggnadsfysikaliska resonemang ingår inte. Framställningen visar hur det ser ut i praktiken. Motiveringar till varför man bygger på ett visst sätt behandlas i en annan litteratur. I det första avsnittet beskrivs summariskt hur byggnadstekniken kommer in i byggprocessen. Därefter g

The problem of communicating one bit over a memoryless Gaussian channel with an energy constraint is discussed. It is assumed that the channel is allowed to be used only two times. An ideal feedback channel is also supposed available. The optimal feedback strategy and the bit-error probability are derived. It is shown that feedback gives a significant performance gain and that the optimal strategy

Popular Abstract in Swedish Tillväxthormon (growth hormone, GH) har en central roll för reglering av tillväxt och ämnesomsättning hos däggdjur. Tillväxthormon frisätts från hypofysen, transporteras i blodet och utövar sina effekter på olika vävnader. Denna avhandling beskriver hur tillväxthormon påverkar ämnesomsättningen i fettceller från råtta, med särskild inriktning på de insulin-lika effekterGrowth hormone (GH) exerts growth-promoting and metabolic effects in mammals. The metabolic effects of GH in adipose tissue are insulin-antagonistic or insulin-like. Cells that just have been exposed to GH are insensitive to the hormone. This study addresses the question of how GH exerts its insulin-like metabolic effects, using primary rat adipocytes as a model system. It is shown that GH increas
