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.

Popular Abstract in Swedish Ordet diffusion kommer från det latinska ordet diffu´sio som betyder spridning. Diffusion förekommer nästan överallt, även om man inte alltid kan se det. Exempelvis består all den luft som vi andas in av en mängd molekyler som diffunderar fram och tillbaka. Eller så kan det vara vattenmolekyler som diffunderar in till plåten på bilen och gör så att den rostar, eller varHindered diffusion occurs in the most different processes, as has been described in this thesis. It is very important to have an understanding of the influence of hindered diffusion on the mass transfer rate, especially when competing rate processes are acting simultaneously. Using mathematical modeling and simulation makes it possible to predict the effects of hindered diffusion. The systems that

BioArray Software Environment (BASE) is a web-based software package for storing, searching, and analyzing locally generated microarray data and information surrounding microarray production. The workflow begins in sample management and, optionally, microtiter plate tracking and ends in visualization and analysis of entire experiments. The relative ease with which new analysis plug-ins can be adde

Two examples of intraplacental choriocarcinoma are described. Both were small and had arisen in otherwise normal third trimester placentas. The covering mantle of many of the villi adjacent to the choriocarcinomas was formed, either focally or wholly, of neoplastic trophoblastic tissue: it is only at this stage of the development of a choriocarcinoma that villous structures are present, and a stud

Guidelines are used in information and quality management systems to ensure high quality by supporting design, production and communication processes. These guidelines can be presented as a conventional system on an intranet suitable for printouts, visualized as a traditional text-based report with a list of headings accompanied by tables and pictures or presented as paper documents in manuals or
