A novel process for the production of biodegradable lubricant-based stocks from epoxidized vegetable oil with a lower pour point via cationic ion-exchange resins as catalysts was developed. This involves two steps, first, ring-opening reactions by alcoholysis followed by esterification of the resultant hydroxy group in the first step. The ring-opening reaction of epoxidized soybean oil with differ

In the first essay of this thesis we develop a model for calculating the net expected value of a swap agreement subject to dual-default risk. The main explanatory variable for the net expected return of a swap is the default intensity of each party measured by the credit rating of the firm. We derive the net expected return of the swap as a function of the credit rating of the firm receiving the f

In this paper, we are concerned with the charging and electrokinetic behavior of colloidal particles exhibiting a high surface charge in the alkaline pH range. For such particles, a theoretical approach has been developed in the framework of the primitive model. The charging and electrokinetic behavior of the particles are determined by the use of a Monte Carlo simulation in a grand canonical ense

We have analysed 994 sites for oncogenes and tumour suppressor genes located within human chromosome bands. The data presented disclose that: 1) These cancer genes build ridges as well as hot spots, which are not related to the position of other types of genes present in these chromosomes. 2) The frequency of cancer genes is not directly related to chromosome length, to the number of DNA bases per

Class I and class II MHC-restricted T cells specific for proteins present in myelin have been shown to be involved in autoimmunity in the central nervous system (CNS). It is not yet known whether CD1d-restricted T cells reactive to myelin-derived lipids are present in the CNS and might be targeted to influence the course of autoimmune demyelination. Using specific glycohpid-CD1d tetramers and clon

This article discusses Swedish gender equality policy and excellent gender equality laws. The problem is not a lack of policy documents and laws, the problem is turning this law system in to practise.

The purpose of this report is to give the background of the chosen methodology to analyse cost-benefit of industrial fire protection. Further more the investigation work has been compiled and some future research topics have been suggested.

Om den politiska svartlistningen av filmarbetare i den amerikanska filmindustrin under 1940- och 1950-talen.

Looking backwards the history of Swedish is characterized by the growing impportance of written language, increased standardization of written and spoken language, growth of the Swedish vocabulary. It is hypothesized that this development will stagnate in the future. The hypothesis ist tested in a discussion against the background of a number of societal phenomena that can be expected to affect th

This study examined 2 samples of adolescents and mothers using a child-based design (Nonshared Environment in Adolescent Development [NEAD] project, N = 395 families) and a parent-based design (Twin Moms [TM] project, N = 236 twin family pairs) to compare genetic and environmental influences on mothering. For both samples, the same measures of positivity, negativity, control, and monitoring were u

A short sketch of the concept of Book and Library History as a field of study, according to the author, holder of the Chair in that subject at Lund University.

A search for the simultaneous presence of two hepatitis C virus (HCV) types in sera of a group of chronically infected intravenous drug users, hemodialysis patients and hemophiliacs from Sweden and Russia was performed with two genotyping methods based on the use of type-specific primers from core and NS4 regions of the viral genome. An important feature of NS4 based assay is that type-specific pr
