A pilot-plant study, made to clarify whether biological denitrification is a possible and suitable method for nitrate reduction of drinking water in Sweden is presented. The concentration of nitrate-nitrogen in un-treated water was 10–15 mg/l. The reactor was a 1.2 m aluminium tube with a inner diameter of 0.19 m. 0.75 m was filled with Filtralite®, expanded clay, through which the nitrate-contami

Purpose: To describe the clinical phenotype of the complete type of X-linked congenital stationary night blindness (CSNB1) with different types of mutations in the NYX gene. Methods: The clinical and genetic data from 18 male patients with eight different mutations from two ophthalmological institutes were reviewed. The variability in refractive error, reduced visual acuity and full-field electror

In this article the authors reflect upon and critically examine signs of a contradiction in higher education which they discuss in terms of the tension between 'use value' and 'exchange value'. Use value here represents learning as something valuable ‘in itself’ whereas exchange value represents learning as an achievement of grades and credits to be ‘traded’ on a market. Their aim in this article

The self-diffusion coefficients of water in casein solutions and gels were measured using a pulsed-gradient spin-echo nuclear magnetic resonance technique (PGSE NMR). The dependence of the self-diffusion coefficient of water on the concentration and structure-of casein is reported. The results were analyzed using a cell model. It was found that the water self-diffusion coefficient is insensitive t

Our aim in this study was to explore women's responses to reported ad-hoc demands for unauthorized user fees during pregnancy and childbirth in Luanda, Angola. Ten focus group discussions were conducted and data were analysed using grounded theory. Women were found to apply six strategies as they "endeavored to cope with demands for unauthorized user fees" (core category): (i) blowing the whistle,

Elevated plasma cytokines is a common finding in Major Depressive Disorder (MDD), although not consistent. It is currently not known whether the inflammatory changes are confined to any specific subgroup of depressive patients. We here analyzed three inflammatory markers in suicidal and non-suicidal depressive patients, as well as healthy controls. Plasma interleukin (IL)-2, IL-6 and tumor necrosi

Patient associations for cancer patients (PACPs) are increasing in number as well as in the number of members. We utilised a questionnaire to investigate how members of 13 PACPs motivated their memberships. The study included 1,810 individuals who had been treated for breast cancer, gynaecological cancer, or prostate cancer. Through questionnaires these individuals were asked to articulate why the
