Background: Surgical extraction of testicular spermatozoa is needed in men with nonobstructive azoospermia (NOA) who wish to become biological fathers. Based on available uncontrolled studies with unspecific patient selection, microdissection testicular sperm extraction (mTESE), having a sperm retrieval rate (SRR) of 50%, is considered the most efficient sperm retrieval procedure. However, no rand

Northern forest ecosystems play an important role in mitigating climate change by sequestrating carbon (C), while additionally providing and regulating other ecosystem services. A majority of the Swedish environmental quality objects (EQOs) that guide Swedish environmental policy and management are associated with the forest, and they have proven difficult to achieve. Several of them relate to the

Candida albicans is a commensal fungus that causes systemic infections in immunosuppressed patients. In order to deal with the changing environment during commensalism or infection, C. albicans must reprogram its proteome. Characterizing the stress-induced changes in the proteome that C. albicans uses to survive should be very useful in the development of new antifungal drugs. We studied the C. al

Context. OH/IR stars are examples of late stellar evolution on the asymptotic giant branch (AGB), and they are, as such, important objects to study. They are also excellent probes of stellar populations, in particular in regions of high interstellar extinction such as the central regions of our Galaxy. Aims. Our goal is to characterise the stellar and circumstellar properties of high-mass-loss-rat

Agricultural intensification has led to dramatic population declines among many farmland bird species. Negative effects of intensive farming in terms of decreased local habitat quality or structural simplification of farmland landscapes have reduced both reproductive outcome and winter survival of many species. Studies investigating agricultural effects on migrating birds using farmland as stopove

The influence of mass-transfer limitations on the performance of immobilized a-chymotrypsin operating in acetonitrile medium has been investigated. The enzyme was immobilized by deposition on various porous carrier materials such as celite, polyamides of different particle sizes, controlled-pore glasses, polypropylene or polyacrylamides. When carrying out kinetically controlled peptide synthesis r

Popular Abstract in Swedish Det finns över 500 kräftarter i världen och vi hittar dem på alla kontinenter utom Antarktis och Arktis. I Sverige finns två arter, den inhemska flodkräftan och den introducerade signalkräftan. Signalkräftan introducerades till stor del för att ersätta förlusten av flodkräfta i många pestdrabbade vatten i södra Sverige. Att det just blev signalkräftan berodde främst på In this thesis I examine the dynamics of crayfish in streams and lakes. I have studied the influence of abiotic and biotic factors on abundance, growth, trophic position, niche breadth, and recruitment of crayfish, by conducting field studies, an outdoor channel experiment and timeseries analysis. Overall, the results show that abundance of crayfish is mostly affected by the abundance of predatory

This work demonstrates how the structure of our Galaxy, the Milky Way, can be unveiled with the use of space astrometry. It consists of two parts, of which the first is a brief introduction to the fields of Galactic structure, covering the Galaxy's stellar constituents, how the Galaxy was formed and how it has evolved over time, both chemically and kinematically. Also the workings of space astrome

BackgroundInterventions that are co-created with end-users, and that are informed by behavior change or implementation theories, support implementation in real world settings. However, injury prevention programs for youth athletes have typically been developed by experts with no, or insufficiently described, end-user involvement and without guidance by theories. The aim of the current study was to

The present study was designed to determine the interrelationships between sex, weaning age, and weaning weight on aspects of physiological and gastrointestinal development in pigs. Forty-eight Large White x Landrace pigs were used in a factorial arrangement with the respective factors being: age at weaning ( 14 or 28 days), weight at weaning ( heavy or light), sex ( boar or gilt), and time after

One of the cleanest ways of transporting goods is at sea. However, the emissions from ships increase and with a wider knowledge about the environmental consequences caused by the emissions, requisite regulations are needed. This thesis deals with air emissions of sulphate (SOx) - and nitrogen oxides (NOx). These emissions cause negative environmental effects both by direct pollution and by forming

Popular Abstract in Swedish Energianvändningen i världen måste minska drastiskt inom en snar framtid för att därmed minska utsläppen av växthusgaser och bromsa klimatförändringarna. Energi och handlande med energikällor har även blivit nationella säkerhetsfrågor. Inom Europeiska Unionen används ungefär 40% av den totala energianvändningen i byggnader, vilket innebär ungefär 36% av det totala koldiThe use of energy is a major global issue both according to climate changes but also in the aspect of national safety tied to the trade with energy sources. Of the total energy use in the member states of the European Union, about 40% is used in residential and commercial buildings. Passive houses are one way to reduce the energy use in buildings and at the same time keep a good indoor comfort. Th

All cellular organisms in aquatic environments are susceptible to virus attack. Viruses are the smallest but most abundant biological entities in freshwaters. This thesis describes interactions between viruses and bacteria in temperate and polar freshwaters with particular emphasis on Arctic and Antarctic aquatic systems. Free virus-like particles in freshwaters are vulnerable and exposed and as p

Popular Abstract in Swedish Den tekniska infrastrukturen i ett land rymmer en rad verksamheter vilka är att betrakta som naturliga monopol. För att hindra att monopolställningen missbrukas har verksamheterna ofta lagts under offentligt huvudmannaskap och regleringar har införts bland annat för att styra prissättningen. Priset regleras vanligtvis genom att avgiftsuttaget måste stå i någon form av rThis thesis, which consists of three studies illustrating different angles of approach, discusses problems pertaining to accounting and allocation costs in municipal water and sewage enterprises. Water and sewage enterprises are financed by charges to users, and are generally run under the auspices of a municipal administration or within the framework of a municipal company. User fees are regulat

The performance of eight fast-response methane (CH4) gas analysers suitable for eddy covariance flux measurements were tested at a grassland site near the Cabauw tall tower (Netherlands) during June 2012. The instruments were positioned close to each other in order to minimise the effect of varying turbulent conditions. The moderate CH4 fluxes observed at the location, of the order of 25 nmol m(-2
