The influence of different dryer fabrics on the contact coefficient has been studied experimentally under various conditions. A bench-scale drying apparatus, in which the fabric could be fixed at variable tensions, was used in the experiments. A technique for measuring the heat flux and surface temperatures of the paper sample and the hot surface was developed. Three paper grades were used in the

A novel calcium-independent serine protease from an alkaliphilic bacterium, Nesterenkonia sp. AL20, has been purified and crystallized at 296 K using sodium formate as the main precipitant. This enzyme is optimally active at pH 10, exhibits high stability towards autolytic digestion and its stability is not affected by the presence of EDTA or detergents. The triangular prism-shaped crystals diffra

The ribosome and tRNA levels of Escherichia coli cells, transformed with a native or mutated Vitreoscilla hemoglobin genes (vhb), were investigated using asymmetrical flow field-flow fractionation (AFFFF). Mutagenesis of vhb by error-prone PCR was carried out to alter the growth behavior of microaerobically cultivated native VHb-expressing E. coli. A VHb mutant, pVMT1, was identified, which was ab

Activation of the contact system has two classical consequences: initiation of the intrinsic pathway of coagulation, and cleavage of high molecular weight kininogen (HK) leading to the release of bradykinin, a potent proinflammatory peptide. In human plasma, activation of the contact system at the surface of significant bacterial pathogens was found to result in further HK processing and bacterial

The feasibility of 17 beta-estradiol (E2) and 17 alpha-ethynylestradiol (EE2) removal by Trametes versicolor was demonstrated in batch and continuous cultures. In batch, E2 and EE2 initially supplied at 10 mg l(-1) were removed by more than 97% in 24 h, which corresponded to volumetric removal rates of 0.43 and 0.44 mg l(-1) h(-1), respectively. A bioreactor inoculated with T versicolor pellets wa

Klimatet och klimatförändringen är för många abstrakt. Något man förstår vikten av men har svårt att intuitivt greppa. Kort och gott så är klimatet en generell bild av vädret över en längre period, vanligtvis sett över 30 år. Ett klimatscenario målar den globala klimatbilden, och observationer tyder på att vi globalt är i linje med det mest pessimistiska framtida klimatscenario, där kännbara föränThe European Corn Borer (ECB) has the potential to markedly reduce the yield from corn plants and in turn affect the economy of farmers. The human world population is increasing and there is consequently an increased number of mouths to feed on a limited area, the Earth, and this makes this an important topic to study. It is thus important to find out whether the ECB likely will be an important pe

Artskyddsförordningen kan föranleda en inskränkning av en skogsägares rådighet över sin skogsbruksfastighet. Rådighetsinskränkningen utgör ett ingrepp i en skogsägares äganderätt, vilket kan berättiga intrångsersättning. För att intrångsersättning ska erläggas krävs dels ett stadgande som berättigar intrångsersättning, dels att pågående markanvändning inom berör del av fastigheten avsevärt försvårForest owners' right of disposition over their forestry property units might be limited by restriction under the Species Protection Ordinance. The restriction of use constitutes a potential violation of the right to property. A forest owner may be entitled to compensation if there is a correlated regulation that justifies compensation and if the restriction of use causes a significant difficul

To this day, the question of what factors drive economic development and catching-up remains deeply controversial in growth literature. The concept of social capability provides a useful framework to investigate the relationship of the parallel processes of transformation, inclusion, autonomy and accountability with economic performance. Nevertheless, there are few attempts to quantify social capa

Syftet med denna studie var att undersöka om det fanns ett samband mellan bra taluppfattning och frekvensoberoende (rak dämpning) i hörselskydd. Ett annat syfte var att undersöka om det fanns någon skillnad på taluppfattningen mellan normalhörande och hörselskadade vid objektiva och subjektiva taluppfattningstester med simulerade hörselskydd, där talet var blandat med talvägt brus. I undersökninge

Många anläggningar projekteras idag under jord. Det gör att det tillkommer krav på vattentätning av berget. Ett sätt att vattentäta en konstruktion är att använda dukmembran eller tunnelduk. Dock råder det oklarheter hur provningsmetoderna för brandklassificering och standarder skiljer sig internationellt. I en alltmer globaliserad värld är det viktigt att provningsmetoderna jämförs med varandra,

This report evaluates a newly made investment in FIB, First Response Crew manager in Medelpad´s Rescue service Association (MRF). The focus is to by interviews and statistics present a picture of the current situation of how well FIB is working. The results of the interviews were categorized into different themes from which the results were later discussed together with the results from the statis
