A large number of legal rules create an obligation to prevent, repair or otherwise mitigate damage to human health or the environment. Many of these rules require that a legally relevant causal relation between human behaviour and the damage at issue is established, and in the establishment of causal relations of this kind scientific information is often pressed into service. This thesis examines

The interactions between uncharged polymers, e.g. ethyl(hydroxylethyl)cellulose (EHEC) and some model polymers, and ionic surfactants in aqueous solution has been studied by using isothermal titration and differential scanning calorimetry. We found that titration calorimetry could give quite detailed information about polymer - surfactant interactions. Values for the critical aggregation concentra

It is easy when studying the literature on the current development toward closer more integrated business to business relationships to get the impression that a close integrated relationship is desired for all circumstances. Instead, this thesis shows that the nature of business relationship is very strongly correlated to product supplied. The focus of this thesis has been a case study between a s

The focus of this article has been to analyse the machinability, with focus on surface integrity, of oxygen-free copper (OFC) and niobium during turning operations. The results from machining OFC proved that all of the tools that was tested can be used to achieve a surface roughness below Ra = 0.8 µm with the correct cutting data. From the results when machining niobium it showed that only the cem

Popular Abstract in Swedish Hjärnskador som uppstår till följd av otillräckligt blodflöde (ischemi) drabbar årligen ett stort antal människor i Sverige och leder antingen till död eller invaliditet och åsamkar stort lidande för den drabbade och dennes anhöriga. Den vanligaste orsaken till hjärnischemi är stroke (slaganfall), som beror på en propp i ett blodkärl eller en hjärnblödning, till en begrBrain ischemia is a major cause of death and morbidity in the industrialized countries. It is mainly caused by stroke, but may also be the consequence of successful cardiopulmonary resuscitation in victims of cardiac arrest, known as transient global ischemia. Although extensive effort in the field of brain research using experimental rodent models, no neuroprotective treatments are at present ava

Who can pick a winner? Since 1974, various types of targeted support have at different times been directed at the development of the heat pump market in Sweden – which in the following decades oscillated violently between soaring sales and collapse. Eventually, however, small heat pumps for space heating of residential buildings have in recent years securely established themselves as a mature and

Deformation of rocks at shallow depths (i.e., at low confining pressures) is primarily driven by the evolution of new fractures or the propagation and coalescence of pre-existing ones. In this paper, fracture evolution from inclined flaws (cuts) in a soft rock deformed under plane-strain uniaxial compression is analyzed using high-resolution digital photographs and Digital Image Correlation (DIC).

Popular Abstract in Swedish Ett av de viktigaste målen för astronomin är att förstå var vi kommer ifrån. Det är naturligtvis många steg som skall förstås, och vart och ett av dessa steg i människans för-förhistoria är komplicerat, så man skall inte förvänta sig att en enskild doktorsavhandling behandlar mer än ett litet hörn av ett av dessa steg. Mitt bidrag gäller förståelsen av hur vår egen galIn order to understand the formation and evolution of the Galaxy it is imperative to know when different components formed. This means at the most basic level that we need to know the ages of stars. The present work demonstrates the many problems inherent in determining the ages of stars through comparison with stellar evolutionary models. Furthermore, solutions to some of these problems are prese

This article is based on a research in the project "The Employment Effects of Computer- Based Technologies in the Office-Service Sector of Developing Countries: a Comparative Study of Banking in India, Malaysia and Singapore", supported by SAREC (Swedish Agency for Research Cooperation with Developing Countries). At the time of this study (1987 to 1990) , Indian bank management was in the process

Human cystatin C is a cysteine proteinase inhibitor belonging to the cystatin superfamily, which previously has been shown to inhibit bone resorption in bone organ culture. The aminoterminal segment, Arg8-Leu9-Val10-Gly11 (RLVG), of the single polypeptide chain of cystatin C constitutes an essential part of its inhibitory center. In the present study, the effect of benzyloxycarbonyl-Arg8-Leu9-Val1

Cysteine cathepsins are proteases that, in addition to their important physiological functions, have been associated with multiple pathologies, including cancer. Cystatin C (CstC) is a major endogenous inhibitor that regulates the extracellular activity of cysteine cathepsins. We investigated the role of cystatin C in mammary cancer using CstC knockout mice and a mouse model of breast cancer induc
