CO2 evasion from freshwater lakes is an important component of the carbon cycle. However, the relative contribution from different lake sizes may vary, since several parameters underlying CO2 flux are size dependent. Here we estimated the annual lake CO2 evasion from a catchment in northern Sweden encompassing about 30,000 differently sized lakes. We show that areal CO2 fluxes decreased rapidly wi

The propagation channel determines the fundamental basis of wireless communications, as well as the actual performance of practical systems. Therefore, having good channel models is a prerequisite for developing the next generation wireless systems. This thesis first investigates one of the main channel model building blocks, namely clusters. To understand the concept of clusters and channel chara

Uterine clear cell carcinoma (UCC) and uterine papillary serous carcinoma (UPSC) are rare entities that differ in clinical behavior from endometrial adenocarcinoma. Compared with endometrioid adenocarcinoma, they more often metastasize early and more commonly in the upper abdomen including the omentum. Treatment programs of UCC and UPSC at different stages vary and range from no adjuvant therapy i

The use of conventional fertilizers is associated with pollution due to leaching and a mismatch between release rates and crop requirements for optimal development. Slow-release fertilizers could address both problems. Here, the synthesis and properties of a zinc fertilizer composed of cellulose microbeads loaded with aqueous ZnSO4 are reported for the first time. UV-vis spectrophotometry showed t

Proteiner är kroppens byggstenar och verktyg, som bland annat bygger upp håret på vårt huvud och ser till så att vår matsmältning fungerar, men det är långt ifrån allt. Denna mångfald bland proteinerna har lett till att man börjat använda dem inom en mängd olika områden, dels för att effektivisera gamla metoder, men också till helt nya produkter. För att producera proteiner som har förmågan att reThe use of fusion proteins has become prevalent within biotechnical applications, offering a method of supplementing a protein with physical or chemical properties inherent to multiple full size proteins or peptides. The thesis work presented in this report was designed to attempt such a fusion, between a recombinant human amelogenin and a fungal cellulose binding domain peptide. The extracellular

Popular science summary As the climate warms and species move northwards, some species encounter populations of a similar species. In this case, the banded demoiselle damselfly Calopteryx splendens is moving north, further into Fennoscandia than it has been known to go before, and is meeting populations of the beautiful demoiselle damselfly Calopteryx virgo. Males of both species set up and defen

Abstract Migration is a widespread phenomenon in nature, observed in many different taxa. Migration is often caused by changes in food availability, physical conditions and predation risks. Moving is energetically costly, and hence migration is likely to be a trade-off between increased survival and an energetic cost for migrating, the cost could take shape in decreased fecundity and lower body c

Mat som kontaminerats av radionuklider genom till exempel radioaktivt nedfall kan ge höga stråldoser till kroppen. Nuklider med långa halveringstider kan ackumuleras i kroppen och ge en hög tidsintegrerad absorberad dos. Personer med kronisk njursvikt kan erhålla höga stråldoser efter intag av radionuklider eftersom många radionuklider utsöndras via njurarna. I den här undersökningen har vi studerHigh internal radiation doses can result from food, contaminated by radionuclides from for example nuclear fallout. Nuclides with long half-lifes can accumulate in the body and give a high time-integrated absorbed dose. Persons with end-stage renal disease can receive high absorbed doses after intake of radionuclides, since many radionuclides are mainly excreted by the kidneys. In this study the d

Nyckeln bakom en lyckad (torrpulver-) formulering För att möjliggöra en lyckad administrering av inhalationsläkemedel är det många faktorer som spelar in. Däribland hur tillverkningen av formuleringen går till. Till skillnad från vad många kanske tror, har inhalation länge använts som ett sätt att administrera läkemedel till lungan. Så länge, att de äldsta fynden daterar tillbaka ända till gamlaFor efficient treatment of many diseases of the lung, it is beneficial to deliver the medicine to the respiratory tract directly. This ensures a rapid response since it can enter the bloodstream directly through the alveolar epithelium. Consequently, also decreases systemic effects due to the local treatment. Dry powder inhaler (DPI) is today one of the most used inhalers for pulmonary delivery.

Så Räddar Vi den Svenska Sandstäppen På sandiga, torra gräsmarker med hög kalkhalt kan så kallad sandstäpp utvecklas. Det är en unik naturtyp som bara förekommer på ett fåtal platser i Europa. I Sverige finns sandstäppen i östra Skåne och enstaka ytor på Öland. Sandstäppen är mycket artrik med flera sällsynta växter och insekter som är viktiga för att kunna bevara den biologiska mångfalden. Idag

Water resources management in a catchment requires the quantification of the water potential. This is usually achieved by the estimation of the hydrological and meteorological characteristics of the basin using observed data to carry out statistical estimates or for use in hydrological models. Hydrological and meteorological data for the Mefou sub basin in Cameroon were collected to analyse the ra
