Popular Abstract in Swedish Syftet med denna studie var att kartlägga kvinnligt skolledarskap. En enkät sän-des till 235 kvinnliga rektorer. Av dem hade 204 tjänst som skolledare under den tid då undersökningen genomfördes och 173 av dem besvarade enkäten. Det externa bortfallet var alltså ca 15 procent. I den fortsatta framställningen avses med bortfall det interna. Nedan ges en sammanfattning avThe purpose of this study was to chart the situation of women principals. By the time the in-vestigation was made the whole amount of women principals in compulsory school was about 16 percent (90/91). Of 235 contacted women, 204 were serving as principals. 173 responded which means 85 percent. The study shows that responsibility rationality are important in women principals' work. They look afte

3-Hydroxypropionic acid was isolated by bioactivity-guided fractionation of extracts obtained from submerged cultures of several endophytic fungi isolated from above-ground plant organs. This compound showed selective nematicidal activity against the plant-parasitic nematode Meloidogyne incognita with LD50 values of 12.5-15 mug/ml. Activity against the saprophytic Caenorhabditis elegans was fivefo

An improved ELISA method for the detection of Staphylococcal. Enterotoxin B (SEB) in protein A preparations is presented. Fab fragments were obtained by digestion with papain of anti-SEB IgG bound to SEB immobilized on Sepharose 4B. Anti-SEB and peroxidase-labeled Fab fragments from secondary antibodies were successfully used in a modified ELISA of SEB in protein A preparations. SEB-Sepharose was

Objective: To identify the reasons and their relative importance why medicines are returned to Swedish pharmacies unused. Setting: A random sample of the pharmacies in Sweden. Method: Interviews using a semi-structered interview form with pharmacy customers returning unused medicines to the pharmacy. Main outcome measure: Reasons given by patients/relatives/carers for returning unused medicines to

Associations with functional groups of natural organic matter (NOM) are of great importance for bioavailability, toxicity, and mobility of trace metals in soils and waters. In this study, the coordination chemistry of copper, Cu(II), in organic soils and dissolved organic matter (DOM) from soils and streams was investigated by extended X-ray absorption fine structure (EXAFS) spectroscopy. In both

The first order second moment (FOSM) method is used for deriving a risk measure for safety of people in hotels. The measure is the reliability index ß. The safety is expressed as the evacuation time margin which is the difference between the available time before untenable conditions occur and the evacuation time. These times are subjected to uncertainty. The reliability index is used to determine

A field sampling device to study the transport of aromatic, persistent chlorinated hydrocarbons from water to air was constructed. It was tested in large, outdoor artificial ponds contaminated with polychlorinated biphenyls (PCBs). The PCB compounds volatilised to air at a rate of 0·9 to 9·6 ng m−2 h−1 depending on levels of PCBs in the water and water temperature.

Human dUTPase, expressed in Escherichia coli, has been crystallized. Single crystals were obtained by the vapour-diffusion technique using 2-propanol and PEG 4000 as precipitants. The enzyme was co-crystallized with the substrate dUTP and a metal chelator EDTA to prevent hydrolysis of the substrate. The crystals belong to the orthorombic space group P212121 with cell dimensions a = 67.51, b = 68.2

Recent work has shown that habitat specialisation can lead to diversification in lacustrine and marine fish species. Here we investigate specialisation in the New Zealand triplefin fish fauna (Tripterygiidae), which has the greatest diversity and disparity of triplefin species in the world with 26 endemic species. Most species are sympatric throughout coastal New Zealand, showing no obvious latitu

OBJECTIVES: To ascertain whether patients with Crohn's disease treated with azathioprine maintained bone mineral mass better than patients treated with steroids alone. DESIGN: Retrospective study. SETTING: University Hospital of Malmo, Sweden. SUBJECTS: A total of 59 patients with ileocolonic, ileocaecal or colonic Crohn's disease. METHODS: Bone mass was assessed by dual photon X-ray absorptiometr
