Associative Multicomponent Polymers in Bulk and at Interfaces

Popular Abstract in Swedish Cellulosabaserade vattenlösliga polymerers egenskaper i lösning och vid ytor har undersökts. Tyngdpunkten har legat på interaktioner med tensider och på effekter av polymerenas utpräglade multikomponentnatur.The solution and interfacial properties of an associative water-soluble cellulose derivative, ethyl(hydroxyethyl)cellulose (EHEC) have been investigated. Main themes have been to study the effect of hydrophobic modification of the polymer (HM-EHEC) and the interactions with surfactants, both in bulk and at interfaces. The association strength of the HM-EHEC network was found to be modulated by eit

The IAU 2000 Resolutions for Astrometry, Celestial Mechanics, and Metrology in the Relativistic Framework: Explanatory Supplement

We discuss the IAU resolutions B1.3, B1.4, B1.5, and B1.9 that wereadopted during the 24th General Assembly in Manchester, 2000, andprovides details on and explanations for these resolutions. It isexplained why they present significant progress over the correspondingIAU 1991 resolutions and why they are necessary in the light of presentaccuracies in astrometry, celestial mechanics, and metrology.

Role of polyamines in the control of the immune response in the brain

Polyamines are essential polycations involved in a large variety of biological functions, including modulation of the nucleic acid conformation, RNA export and their degradation, protein synthesis, eIF-5A posttranslational modification, signal transduction, cell growth and differentiation, and tumor progression ( 1 –bi3. These various aspects in the biology of polyamines are addressed in other sec

Increased focus on values. A tool in stress prevention?

Background and purpose Can an increased focus on values in working life be a factor in stress prevention? Values are defined as the shared principles which guide behaviour in an organisation. The purpose of this study was to describe how patients with musculoskeletal pain perceive the importance of values in relation to coping with daily stress and in relation to health.
