  1. 11. Development of Molecular Biology and Bioinformatics Tools From Hydrogen Evolution to Cell Division in Cyanobacteria

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Fernando Lopes Pinto; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; hydrogen; RNA; bioinformatics; RT-PCR; RACE; transcription; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; NATURAL SCIENCES Biology Other biology Bioinformatics; NATURVETENSKAP Biologi Övrig biologi Bioinformatik; Molecular Biology; Molekylärbiologi;

    Abstract : The use of fossil fuels presents a particularly interesting challenge - our society strongly depends on coal and oil, but we are aware that their use is damaging the environment. Currently, this awareness is gaining momentum, and pressure to evolve towards an energetically cleaner planet is very strong. READ MORE

  2. 12. Catalytic conversion of biomass-derived synthesis gas to liquid fuels

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Rodrigo Suárez París; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuels; Fischer-Tropsch wax; higher alcohols; hydroconversion; kinetic modelling; methanol cofeeding; microemulsion; MoS2; noble metal; syngas; Chemical Engineering; Kemiteknik;

    Abstract : Climate change is one of the biggest global threats of the 21st century. Fossil fuels constitute by far the most important energy source for transportation and the different governments are starting to take action to promote the use of cleaner fuels. READ MORE

  3. 13. An Experimental Study of Fischer-Tropsch Fuels in a Diesel Engine

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Monica Larsson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Alternative Fuels; Fischer-Tropsch; GTL;

    Abstract : Alternative fuels for Diesel engines include ester-based fuels (derived from sources such as rapeseed, soybeans and palm oil), dimethyl ether, and various synthetic fuels. Use of these fuels could contribute to a cleaner environment, reduce global warming and improve the human health by reducing levels of harmful emissions. READ MORE

  4. 14. Ultra high-pressure compaction of powder

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Sven Berg; Luleå tekniska universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Sintering at high-pressure improves the properties of the material, either through new sintering aids becoming available or through improving intergranular bonding. This gives the manufactured products potential advantages like faster cut rates, and more precise and cleaner production methods that add up to cost efficiency and competitive edge. READ MORE

  5. 15. Energy Efficient Longitudinal Control

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Rickard Arvidsson; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous Vehicles; Optimal Control; Hybrid drivetrain control; Combustion Engines;

    Abstract : Vehicles are contributing to global and local environmental problems as a result of fossil fuels. A majority of the combustion engine population is driven by fossil fuels and electrified vehicles are also to a large extent dependent on electricity production from fossil fuels. READ MORE
