21. Partially Premixed Combustion (PPC) for low loadconditions in marine engines using computationaland experimental techniques
Master-uppsats, KTH/MekanikSammanfattning : Diesel Engine has been the most powerful and relevant source of power in the automobile industryfor decades due to their excellent performance, efficiency and power. On the contrary, there arenumerous environmental issues of the diesel engines hampering the environment. LÄS MER
22. VVA-strategier för avgastemperaturhöjning på en HD-Dieselmotor
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. LÄS MER
23. Avgång av lustgas från luftningsprocessen på Käppalaverket
Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaperSammanfattning : The requirements for wastewater treatment plants (WWTP) are gradually increasing, partly because of higher incoming loads, which in turn require a more efficient treatment process. In parallel with environmental and economic goals there are also desires to lower energy consumption without compromising the wastewater treatment. LÄS MER
24. Analys av skillnader och likheter i EU-länders långsiktiga klimatstrategier
Uppsats för yrkesexamina på avancerad nivå,Sammanfattning : De internationella klimatförhandlingarna handlar om att hitta lösningar för att stabilisera halten av växthusgaser i atmosfären och att uppnå tvågradersmålet. För att uppnå målet finns olika utsläppsmål att sträva mot. LÄS MER
25. Climate change impacts on crop yields and adaptive measures for agricultural sector in the lowlands of Lesotho
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Summary: Climate change has emerged as the most outstanding of the environmental challenges and there is a necessity to evaluate its impacts on the vulnerable development sectors such as agriculture. In this study, spatially adjusted general circulation models and crop models were used to simulate climate change scenarios and the associated cereal crops yields for the western lowlands of Lesotho for the year 2030-2050 and 2080-2100.
