Kinetics of chlorobenzene hydrodechlorination have been measured over Ni on SiO2, Al2O3, MgO, activated carbon and graphite. A stepwise variation of E-a is analysed using the selective energy transfer model where E-a is identified as the vibrational energy associated with an excitation of the chlorobenzene out-of-plane C-H bending mode. Variation of E-a with vibrational quantum number yields a vib
It is well established that fibroblasts play a crucial role in pathophysiological extracellular matrix remodelling. The aim of this project is to elucidate their role in normal physiological remodelling. Specifically, the remodelling of the human cervix during pregnancy, resulting in an enabled passage of the child, is used as the model system. Fibroblast cultures were established from cervices of
purpose of this study was to elaborate a model for estimating the caries-reducing effect of a preventive measure with due consideration of background factors. The material comprised 50 children, who had consumed NaF tablets regularly during preschool age, and 76 comparable children who had never consumed NaF tablets. They were all examined at 12 and 13 yr of age. Information on caries and, as conf
Pheromones are intraspecific chemical signals serving as a ubiquitous form of communication, particularly among insects. Female sex-pheromone signals act as the core constituent in the specialized odour-mediated moth mate-recognition system. Female moths typically release multicomponent mixtures of alcohols, aldehydes or acetates. The biosynthetic machinery controlling pheromone production compris
In October 1989, a 24-year-old Kurdish immigrant from Iraq was brought before the Sandviken Lower Court in Sweden charged with assaulting, coercing and threatening his pregnant ex-girlfriend who had left him to live with another man. Although, the court found the defendant guilty as charged, it nevertheless released him on a suspended sentence and a fine of 3000 Swedish Kronor. Conviction on this
In the present thesis, the influence of the immunosuppressive drug FK506 on mitogen-induced changes in the expression of subunits a and ß of the IL-2 receptor by isolated human peripheral blood mononuclear cells has been studied. Up-regulation and release of the a-chain were potently depressed by FK506, even in the presence of exogenous IL-2. In contrast, up-regulation of the ß-chain on these same
I am concerned with Mary Wollstonecraft’s political morality. In it she makes no moral room, I claim, for emotional responses or emotional reasons for action, and it is important that she doesn’t. I will start by pointing at reasons for why it is important. I will then go on to analyse the content of and relations between her main political concepts: the triad of liberty, equality and virtue, with
In this article, I apply René Girard's theory of generative violence to the international law relating to the use of force. I argue that texts of international law make gestures of referral towards an immanent normativity on the fettering of divine violence. The means to this end is a form of sacrificial violence that seeks to promote the preservation and cohesion of the ‘international community’.
The aerosol size distribution in 11 dwellings was measured using an electrical mobility analyser (TSI 3030). Large variations in the aerosol concentration, e.g. in connection with cooking and smoking were detected both within a single dwelling and between different dwellings. A typical size distribution shows an area median diameter of 0.2 µm with a geometrical standard deviation of about 2. Varia
Energy simulation programs are commonly used to calculate the climate and energy requirements in glazed spaces and adjacent buildings. However, these programs have usually been developed to study buildings with ordinary window sizes. Comparisons of four simulation programs were carried out for a sunspace with an adjacent room. The distribution of solar radiation between the glazed space and the ad
This article presents an analog implementation of the signal component generator (SCG) of the CALLUM2 linear transmitter architecture. The proposed SCG is suited for integration in a standard 0.35 μm CMOS process, and has from simulations proven to be adequate when operating on an EDGE modulated baseband signal with a data rate of 270.833 ksymb/s. The total current consumption of the SCG is 2.0 mA
Energy efficient wood frame buildings give besides a number of positive effects also risks for moisture damages. To avoid moisture damage in wood houses some parts of the Swedish construction industry use WUFI 1D calculation tool in the design phase. The purpose of this study is to demonstrate the coupling between measured and WUFI 1D calculated values of relative humidity and temperature. The fir
In this paper, a technique for calibrating a camera using a planar calibration object with known metric structure, when the camera (or the calibration plane) undergoes pure translational motion, is presented. The study is an extension of the standard formulation of plane-based camera calibration where the translational case is considered as degenerate. We derive a flexible and straightforward way
Nuclear spin relaxation is a powerful method for studying molecular dynamics at atomic resolution. Recent methods development in biomolecular NMR spectroscopy has enabled detailed investigations of molecular dynamics that are critical for biological function, with prominent examples addressing allostery, enzyme catalysis, and protein folding. Dynamic processes with similar correlation times are of
