Ett nytt protein som hjälper Haemophilus bakterien att fastna i luftvägarna På ytan av luftvägsbakterien Haemophilus influenzae, finns en rad proteiner. Genom att flytta dessa proteiner till en annan bakterie, Escherichia coli, har vi visat att de kan binda till ett protein som finns i våra luftvägar. Bindningen till luftvägarna är ett första steg i etableringen av en infektion som sedan gör oss

PEJL PÅ RASTANDE FLYTTFÅGLAR Varje vår och höst passeras Falsterbo av miljontals flyttfåglar. Många mellanlandar här för att fylla på sina bränsledepåer och vila upp sig inför nästa etapp på resan. Frågor som är intressanta inom flyttfågelforskningen är bland annat hur länge fåglarna rastar och om längden på vistelsen är kopplad till art, ålder, kön, fettreserver eller flyttningsstrategi (i det hABSTRACT The aim of this study was to examine autumnal stopover strategies of migratory passerines, with the main focus on stopover duration, departure time and departure direction in relation to biometrics (age, sex and fat reserves), different migratory strategies (long, short-to-medium and partial migration) and weather conditions. During the autumn migration season of 2010, in conjunction wi

In the E. ON sponsored research project, Distibution LABoratory, at the Department of Industrial Electrical Engineering and Automation at LTH the impact of the increased move towards use of cables in the Swedish distribution grid is examined. The project also built a model of a small distribution grid. The model was used to simulate a Petersen coil earthed grid system. Petersen coil earthing lower

Solar storms are a phenomenon that has a wide array of adverse consequences on technological systems, power systems in particular. During severe solar storms a geomagnetically induced current (GIC) starts to flow through long conducting structures, such as power lines and pipelines. The probability of solar storms has a roughly linear relation with the sunspot activity level which varies in 11 yea

Upptäcka gener inblandade i diabetes I många sjukdomar, så som diabetes, spelar människans gener en viktig roll i vem som insjuknar och hur utvecklingen sker. Därför är det viktigt att, i den mån det går, identifiera dessa gener så vid insjuknande, ge varje patient en mer specialiserad vård som kan bromsa sjukdomsförloppet. Diabetes är en metabolisk sjukdom där kroppen inte kan reglera glukoshaAbstract Aims/hypothesis Diabetes, a metabolic disease rapidly increasing worldwide, is triggered by both genetic and environmental factors. Longitudinal studies, such as the Malmö Prospective Project (MPP), give a unique opportunity to study life-long risk of developing a disease. In MPP, more than 2,000 individuals developed diabetes during a mean 25-year follow-up time. However, patients with

The objective of this master thesis is to review the present and future condition of generator step up power transformers at the combined heat and power plant Öresundsverket, in Malmö. The objective of this work was to prolong the lifetime of power transformers at Öresundsverket. The thermal properties of power transformer are been taking into consideration for their life time assessment. The most

The Archaean Yilgarn craton in Western Australia is a granite greenstone belt with abundant economically important mineral reserves, including several world-class gold deposits such as the giant Kalgoorlie deposit. Structural controls on gold deposition and the fact that most deposits were formed later in the craton’s tectonic history, has resulted in the general acceptance of a late-orogenic str

Vilka fördelar har gruppundervisning i slagverk? Detta är frågan som genomsyrar hela studien. Studien syftar till att lyfta fram aktiva slagverkspedagogers syn på gruppundervisning inom musik- och kulturskola Studien bygger på kvalitativ forskning som metod och fyra aktiva slagverkspedagoger har intervjuats. För att ge studien mer trovärdighet har informanternas tankar jämförts med tidigare forsknPlay together – teaching percussion in groups The purpose of this study is to investigate and to lift forward what percussion teachers who work at the Swedish municipal school of music think are the benefits and negative sides of teaching in groups. The study is based on qualitative research where four percussion teachers have been interviewed about their opinions in this matter. Their ideas and t

The impact of microcredit on women’s empowerment remains debated. While some studies suggest that microcredit helps women increase their income earning abilities, leading to greater power within the household, others argue that men often take control over the microcredit allocated to women, which leads to a more vulnerable position within the household for women. This paper evaluates the impact of

Cultural heritage tourism is regarded as one avenue that can be used to stimulate the economic viability of an area; this is strongly believed by the tourism proponents in the parish of Manchester, Jamaica. With a lagging economy, and various studies done in the area, there has been no significant movement by policy makers towards implementing a sustainable tourism product, much to the ire of the

Abstract Over the past decade, mass spectrometry has had an essential role in improvement of proteomics techniques. New instrument and analytical protocol developments have made mass spectrometry one of the most widely used analytical methods in quantitative proteomics. Today one of the commonly used protocols in proteomics is digestion of proteins to peptides and analysis of the peptides with li

Abstract To develop a genetic system for the extreme thermophile Caldicellulosirruptor saccharolyticus is the next step in improving hydrogen productivities. Genetic systems are powerful tools to understand the metabolic network of the microorganism and to obtain high hydrogen productivities and yields. The primary aim of this project is to develop an expression vector for C. saccharolyticus. Pre

Abstract Agricultural intensification is causing a worldwide loss in biodiversity, and organic farming has been proposed as a valid method for preserving it. Studies have shown that organic farming increases species abundances, however the taxonomic breadth of communities may be an additional important biodiversity measure which is not affected by study intensity or sample size. The aim of this s

Abstract Streptococcus pneumonia secretes a number of glycosidases that modify the glycosylation state of immune defense molecules such as immunoglobulins. Modulation of the glycan on IgG can affect the function and structural properties on IgG and cause immune disorders. StrH is a β – N acetylglucosaminidase that removes terminally linked N-­‐ acetylglucosamines from human glycoproteins. It is d

Despite records in consumer prices on fuel, the Swedish fleet of cars is growing even larger, and today consumes more petrol gas and diesel combined than ever before. The Swedish Government has explicitly defined environmental goals for 2020, one of which stating that climate emissions should be cut by 40 percent compared to 1990. One of the most important management control tools for the governme

Denna uppsats behandlar uppsägningsgrunden arbetsbrist och begränsningar i arbetsgivarens arbetsledningsrätt vid uppsägning. Med arbetsbrist avses i lagens mening inte enbart brist på verkliga arbetsuppgifter för arbetstagarna utan även en mängd andra situationer där arbetstagare blir överflödiga. Lagen om anställningsskydd är, i situationer då arbetsbrist föreligger, inte tänkt att ge ett befattn

Denna studie har undersökt mixade stereotyper genom att mäta uppfattningar på dimensionerna värme och kompetens för två etniciteter, asiat och afrikan. Tidigare forskning har i huvudsak genomförts på explicit nivå, vilket gjorde det intressant att testa ifall mixade stereotyper gick att finna på implicit nivå. Det hade inte heller gjorts implicita mätningar mot etniciteter och studien under-sökte
