1. En jämförelse mellan gröna-, metall- och gråa tak för ett oisolerat parkeringshus utifrån dess olika temperaturer och dagvattenhantering
Kandidat-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknikSammanfattning : Since climate change increases and changes constantly, it contributes to higher average temperatures, ice melting and has a great impact on our ecosystem. This will then lead to a warmer climate, which means increased precipitation and milder winters. One of the reasons to climate change is urbanization, meaning people moving to the cities. LÄS MER
2. Vilka potentiella behandlingsalternativ finns det mot bakteriella infektionssjukdomar som ligger i fas 2-3 studier eller som man bedriver forskning på?
Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)Sammanfattning : Resistance against antibiotics has become a global world problem. The effect of antibiotics is affected by the resistant bacteria and they cause infections that are difficult to treat. This is a major burden on the healthcare and leads to increased mortality. Globally, about 700,000 people die each year because of antibiotic resistance. LÄS MER
3. Material characterization of multi-layered Zn-alloy coatings on fasteners : Effects on corrosion resistance, electrical conductivity and friction
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Electroplated zinc-alloy coatings have been used on fasteners in the automotive industry for many years. The coating often consists of three layers: a zinc-alloy layer, a passivation layer and a sealer or top-coat. LÄS MER
4. Kontroll av zinkskikt på monterat räckesmaterial
M1-uppsats, KTH/Byggteknik och designSammanfattning : Kontroll av zinkskikt på monterat räckesmaterial som görs ute i fält saknar en fastställd metod. Zinktjockleken har ett minimum tjocklekskrav enligt den svenska standarden ISO 1461:2009, som bestäms av dimensionen på ståldetaljens tjocklek. LÄS MER
5. How does urban discharge affect a lake in a recreational area in central Sweden? : a comparison of metals in the sediments of three similar lakes
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Metal contamination of lakes can bring negative effects to aquatic biota, and to the general health of the ecosystem. Urban discharge is a known source of common metals. In cold regions, snow disposal sites further enhances the risk of contaminating recipient lakes, due to accumulation of pollutants. LÄS MER
