Popular Abstract in Swedish Att kunna resa och transportera gods är en del av människors vardag i dagens samhälle. De flesta av dessa transportmedel använder förbränningsmotorer på grund av dess flexibilitet, låg global kostnad och lång körsträcka. Utsläpp i olika former är en oönskad biprodukt av förbränningsmotorer som är skadlig både för människor och för miljön. Diesel motorer är idag bland deInternal combustion engines have been an important technological field for more than a century. It has had an important impact on society through improved transportation and industrial applications. However, concerns about environmental effects of exhaust gases and utilization of oil resources have pushed development of combustion engines towards cleaner combustion and higher efficiencies. The d

The increasing demand on improved reception and high data throughput brings into focus the design of compact multiband antenna terminals with diversity reception capability. In particular, the influence of user on diversity performance is of current interest. In this paper, the diversity performance of compact tri-band antennas (WCDMA850, WCDMA1800 and UMTS 2100) for mobile handsets is evaluated i

The evolution of media has gained much headway this past decade and has outpaced many countries’ ability to keep up. It has even left linguistic gaps in the Arabic language, and has sparked one Jordanian, Muhammed Jaradat, to create new Arabic terminology to fill this social media language gap. As internet proliferation increases in Arab countries and access to higher connection speeds becomes ava

Popular Abstract in Swedish Mjölk och mjölkprodukter har länge varit en viktig del av vår föda. Studier som undersöker förekomst av sjukdomar i olika befolkningsgrupper och vilka faktorer som påverkar dessa, så kallade epidemiologiska studier, har visat på ett samband mellan mjölkdrickande och minskad risk för flera cancerformer, bland andra tjocktarmscancer. Man vet att kalciumhalten i mjölk tillThis thesis concerns the bioactive peptides lactoferricin and ubiquitin and findings suggesting that they have ability to modify the risk of cancer. It is known that components in bovine milk may improve human health and modify the risk of diseases. Examples of such compounds are bioactive peptides, i.e. peptides with an effect on the body beyond the purely nutritional. Using cell culture as a mod

The production of jets with low transverse momenta (mini-jets) in deep inelastic electron-proton scattering is studied. The analyses uses data taken with the H1 detector at HERA during the years 1999 to 2000. The events are required to contain either at least one leading jet of Pt > 5 GeV (the inclusive 1-jet sample) or at least two hard jets where one of them has to be at an angle larger than 140
