Molecular information on the dissolution of polydisperse polymers: Mixtures of long and short poly(ethylene oxide)

A systematic study of the dissolution of dry, polydisperse polyethylene oxide) (PEO) samples, obtained from mixtures of low-molecular-weight and high-molecular-weight PEO, was made. During the dissolution process, the individual release of the low-and high-molecular-weight fractions was monitored. The highmolecular-weight/low-molecular-weight ratio controls the release rate, and the fraction of hi

Yrast Superdeformed Band in 59Cu

High-spin states in 59Cu were populated using the fusion-evaporation reactions 28Si+40Ca at a beam energy of 125 MeV and 36Ar+28Si at a beam energy of 143 MeV. The Gammasphere array in conjunction with ancillary detector systems allowed for the identification of a superdeformed rotational band in 59Cu, which was firmly linked to low-spin yrast states. Using directional correlations of oriented sta

Direct capture of product from fermentation broth using a cell-repelling ion exchanger.

A new technique for treating anion exchangers has been proposed allowing direct capture of the fermentation product, shikimic acid directly from the cell-containing fermentation broth. A layer of hydrophilic polymer, poly(acrylic acid) (PAA) has been physically adsorbed on the anion exchanger followed by a covalent cross-linking of PAA. The PAA layer is penetrable for small molecules despite being

Recursive parametrization and invariant phases of unitary matrices

We present further properties of a previously proposed recursive scheme for parametrization of n-by-n unitary matrices. We show that the factors in the recursive formula may be introduced in any desired order. The method is used to study the invariant phases of unitary matrices. The case of four-by-four unitary matrices is investigated in detail. We also address the question of how to construct sy

Bowel function among people 75+ reporting faecal incontinence in relation to help seeking, dependency and quality of life.

Aims and objectives. The aim was to compare faecal incontinence and related bowel symptoms among men and women and being dependent or not (aged ≥75 years) and furthermore to identify which bowel symptoms predicted help seeking, dependency and low quality of life (QoL). Background. Faecal incontinence (FI) in old age is a common condition and influences daily life to a great extent, although few a

Energieffektivisering i bostaden. Förändringar i hushållsarbete för kvinnor och män.

Syftet med projektet har varit att kartlägga och analysera hur kvinnors och mäns vardagsliv förändras då de deltar i ett energibesparingsprojekt, avseende arbetsuppgifter, ansvarsfördelning och energieffektivt beteende. Detta omfattar förändringar i hemmets sysslor för män och kvinnor, hur mäns och kvinnors tidsanvändning och arbetsbörda förändrats, liksom deras vilja att delta i åtgärder för ener

Det svenska standardspråkets uppgång – och fall

Overview of the development of the Swedish standard language, written and spoken, from the end of the middle ages. The written standard was fully developed around 1800 and the spoken around 1900. Some factors are discussed which might weaken the standard again in the 21st century.

Macropyge (Promacropyge) Scandinavica new species; The first macropyginid trilobite recorded from the Furongian of Baltica

Macropyge (Promacropyge) scandinavica new species is described from the Furongian Peltura minor Zone on northwestern Mount 14 Kinnekulle, southcentral Sweden. It represents the first macropyginid trilobite recorded in Baltica. M. (P.) scandinavica closely resembles other species of the same subgenus from southeast China, suggesting a correlation between the Scandinavian P. minor Zone and the Lotag

Dynamics of hip joint effusion after posterior soft tissue repair in total hip arthroplasty

Dislocation after total hip replacement is more common in the early, postoperative period. Postoperative intraarticular haematoma and remaining seroma fluid and/or weakened posterior soft tissue wall may be contributing factors. Our purpose was to compare and follow with sonography the resorption of the postoperative volume of intraarticular fluid/synovial oedema after total hip arthroplasty (THA)

Trousseau's syndrome - what is the evidence? A population-based autopsy study

Despite numerous studies documenting the association between cancer and venous thromboembolism (VTE), the reason for the excessive risk in certain cancers remains obscure. No large-scale studies have yet investigated the independent effects of cancer type, site and growth pattern. Between 1970 and 1982, 23,796 standardised autopsies were performed, representing 84% of all in-hospital deaths in an

Clinical improvement after 6 weeks of eccentric exercise in patients with mid-portion Achilles tendinopathy - a randomized trial with 1-year follow-up.

Achilles tendinopathy is common and treatment with eccentric exercises seems promising. We designed a prospective randomized clinical trial to test the hypothesis that eccentric calf muscle exercises reduce pain and improve function in patients with Achilles tendinopathy. Forty-four patients were recruited from primary care (mean age: 45 years; 23 women; 65% active in sports) and randomized to thr

Design and Analysis of Highly Linear Integrated Wideband Amplifiers

This dissertation deals with techniques for designing integrated amplifiers with high linearity. Amplifiers with operating frequencies from Audio to RF have been built. An enhanced feedback configuration, capable of very low distortion, is presented. Also presented is a statistical method for relating the distortion of a wideband signal to the total harmonic distortion (THD) of a single tone. Two

Physical performance, toxicity, and quality of life as assessed by the physician and the patient

The aim of this study was to study the relationship between physician-assessed quality of life parameters, i.e., toxicity and physical performance, and patients' self-reports of their quality of life (QoL). QoL was assessed at baseline and before each treatment. using the EORTC QLQ-C30. The WHO performance score (PS) and toxicity were assessed in physician interviews. The correlations between the

Direct evidence of defect annihilation during structural relaxation of amorphous indium phosphide

Extended x-ray absorption fine structure measurements have been used to characterize the low-temperature, thermally induced structural relaxation of amorphous InP. We show reductions in both chemical and structural disorder associated with homopolar and heteropolar bonding, respectively, are operative during structural relaxation of this amorphous compound semiconductor. The latter is analogous to

Treatment of effluent from alkali extraction with ultrafiltration and reverse osmosis

Effluent from alkali extraction of chlorinated pulp was treated with ultrafiltration (UF). Three different ultrafiltration (UF) membranes were tested. The permeate from one of the UF membranes was further treated with reverse osmosis (RO). Titration curves for the permeates from the different UF and R0 membranes were determined. The concentration of charged compounds was calculated from the titrat
