1. 31. Patterns and Processes of Evolution in Sundaland

   Författare :Robert-Jan den Tex; Jennifer A. Leonard; Lawrence R. Heaney; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Systematics and phylogenetics; Systematik och fylogeni; Genetics; Genetik; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : Biodiversity in the tropics is disproportionately high compared to other habitats, and also under disproportionate threat from human impact. It is necessary to understand how this diversity evolved and how it is partitioned across space in order to preserve it. LÄS MER

3. 32. Solute Carriers in Metabolism : Regulation of known and putative solute carriers in the central nervous system

   Författare :Emilia Lekholm; Robert Fredriksson; Helgi B. Schiöth; David Drew; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Solute Carriers; transporter; amino acid starvation; glucose metabolism; MFS; SV2; Medical Science; Medicinsk vetenskap;

   Sammanfattning : Solute carriers (SLCs) are membrane-bound transporter proteins, important for nutrient, ion, drug and metabolite transport across membranes. A quarter of the human genome codes for membrane-bound proteins, and SLCs make up the largest group of transporter proteins. LÄS MER

4. 33. Constructing Transit Corridors : The Politics of Public Transport Policy and Planning in Malmöhus and Skåne 1970-2020

   Författare :Jens Portinson Hylander; Robert Hrelja; Jamil Khan; Fredrik Pettersson-Löfstedt; Jane Summerton; Jonathan Metzger; Miljö- och energisystem; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public transport; Rationality; power and politics; Planning theory; policy studies;

   Sammanfattning : Planning local and regional public transport in so-called ’transit corridors’ – i.e., to concentrate infrastructure and resources to few, but more attractive corridors in a city or a region – is commonplace in contemporary public transport planning. This has not always been the case, however. LÄS MER

5. 34. Plant-microbe-soil interactions and soil nitrogen dynamics in boreal forests : development of nitrogen limitation

   Författare :Robert Blasko; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Widespread nitrogen (N) limitation of plant growth in boreal forests is a well recognized phenomenon. Yet, the mechanisms responsible for the development of N limitation are unknown. By exploring the linkage between N cycling and microbial community structure, this thesis examines the role of soil microorganisms in N limitation development. LÄS MER

7. 35. Digital twinning for ports : from characterization to operations’ modelling

   Författare :Robert Klar; Vangelis Angelakis; Anna Fredriksson; Anders Andersson; Niklas Arvidsson; Theo Tryfona; Statens väg- och transportforskningsinstitut; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Digital twins; Ports; Operational efficiency; Collaborative decision-making; Port decarbonization;

   Sammanfattning : Ports are actively pursuing greater operational efficiency to effectively handle the increasing global flow of goods, while striving to improve the energy efficiency of their operations to comply with new environmental regulations. As a result, innovation-leading ports have begun to recognize the potential of digital twins to overview, coordinate and optimize port processes, resulting in energy savings, and reductions of costs and of CO2 emissions.
