Thermodynamic Studies of Macromolecular Models

The thermodynamic properties of single chain polyelectrolyte and protein models are studied using Monte Carlo simulations and (for the polyelectrolyte models) variational calculations and high- and low-temperature expansions. A variational method is used for minimizing Lennard-Jones energies and for estimating end-to-end distances for a rigid Coulomb chain at finite temperatures. A polyelectrolyte

Exploring the Adaptation of Enterprise Systems Implementation Methodology: A Morphogenetic Approach

Enterprise Systems Implementation Methodology (ESIM) is considered to be a critical factor for successful Enterprise Systems (ES) implementations. In spite of ESIM’s potential and significance for practice, little attention has been paid to this object of study in ES literature. Moreover, current studies reveal contradictory findings and provide a fragmented understanding. The purpose of this pape

Letters from Sir James Spens and Jan Rutgers

When Axel Oxenstierna, Chancellor of Sweden, died in 1654, Sweden was a great power. In 1612, however, when Oxenstierna took office, Sweden was on the verge of collapse. In the east, she was menaced by Muscovy, in the south-east by Poland, and in the west by Denmark. One of the means to save the Swedish realm was through active diplomacy. Two important figures in Oxenstierna’s diplomatic network w

High-chromaticity Optics for the MAX IV 1.5 GeV Storage Ring

The MAX IV facility currently under construction in Lund, Sweden will include a 1.5 GeV storage ring. To prevent head-tail instability, the negative natural chromaticities of the MAX IV 1.5 GeV storage ring have been corrected to positive values using sextupole gradients in the focusing quadrupoles along with dedicated sextupole magnets. To allow adjustment of the chromaticity correction, weak cor

Portland Cement Clinker - Composition and Hydration

The crystal structures of the main Portland cement clinker phases are reviewed and two anion centered models of Ca3SiO5 and Ca2SiO4 are presented. The effects of minor elements on the clinkering process, and on the qualitative and quantitative phase compositions of Portland cement clinker are discussed. The distribution of some minor elements (F, Na, Mg, S, K, Ti, Mn, and Sr) has been investigate

On the binding of growth-promoting polyamines to proteoglycans: Implications for growth-regulation and polycation-mediated gene transfer

Initial investigations were directed at studying the interaction between polyamines and various glycosaminoglycans (GAGs). The polyamine spermine displayed binding to dermatan sulphate (DS) and heparan sulphate (HS) with similar (Kd, 3.9 x 10-4 M) and higher (Kd, 0.37 x 10-6 M) affinity, respectively, than to DNA. Antiproliferative spermine-binding DS fragments (tetra- to decasaccharides), and aff

Reliability test-retest of the Nordic Assisted Mobility Evaluation (NAME 1.0).

This paper describes preliminary results from the test-retest of the NAME 1.0. Four scales were tested: Mobility-related participation frequency; Mobility ease/difficulty; Mobility dependence; Extent of assistance in mobility. The test was conducted in the five Nordic countries. In all 147 mobility device users took part in the study, mean age 60 years (range 19 - 93). Each participant was intervi

Knowledge Sharing Across Borders - A Study in the IKEA World

To enter new markets is not easy. The most obvious challenge, at least judging from the majority of literature on internationalization, is to understand the new market thus taking a market(ing) perspective. External aspects of internationalization are often stressed, while internal aspects, focusing on why organizations fail, are less developed or examined. In order to better understand the intern

Ströja kyrka – en aristokratisk medeltidskyrka

Today, Brahe Church mainly exhibits signs of the period of greatness of Visingsö island during the seventeenth century. However, there are also traces from much earlier periods. Ströja Church was built during the twelfth century, when the House of Erik and the House of Sverker contested for the title of king and the island of Visingsö had a prominent position in the new country of Sweden. We do no
