    Sammanfattning : Clusters are finite ensembles of atoms or molecules with sizes in the nanometer regime (i.e. nanoparticles). This thesis present results on the geometric and electronic structure of homogeneous and heterogeneous combinations of atoms and molecules. LÄS MER

  3. 2. Unlocking Potentials of Innovation Systems in Low Resource Settings

    Författare :Julius Ecuru; Blekinge Tekniska Högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cluster; Innovation; Innovation System; Low resource setting; Research; Science; Technology; Technoscience; Triple Helix; Uganda;

    Sammanfattning : This study examined the dynamics, challenges and opportunities of developing innovation systems in low resource settings with a particular focus on Uganda. It applied perspectives of technoscience and concepts of innovation systems, triple helix as university-industry-government relationships, mode 2 knowledge production and situated knowledges in understanding the context, identifying key policy issues and suggesting ways to address them.

  4. 3. Exploring evolutionary and chemical space using chemoinformatic tools and traditional methods in pharmacognosy

    Författare :Astrid Henz Ryen; Anders Backlund; Thierry Kogej; Fernando B. Da Costa; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; angiosperm chemistry; physicochemical properties of plant specialized metabolites; chemical diversity; chemical space; sesquiterpene lactones; scaffold diversity; molecular framework; cluster analysis; ECFP6; Lindera benzoin; sesquiterpenes; anti-inflammatory; Farmakognosi; Pharmacognosy;

    Sammanfattning : The number of new drugs coming to the market is declining while interest in lead discovery from natural resources is seeing a revival. Although methods for isolation and identification of natural products have advanced tremendously, methods for selection of potential leads have fallen behind. LÄS MER

  5. 4. Urban-Based Agriculture and Poultry Production : The Case of Kisumu and Thika in Kenya

    Författare :Samuel Omondi; Institutionen för kulturgeografi och ekonomisk geografi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urban agriculture; urban-based rural agriculture; poultry production; poultry value chain; food security; Kenya;

    Sammanfattning : Kenya’s population is rapidly growing and urbanising. Poverty and problems of food insecurity are equally urbanising at an unprecedented rate. Formal employment has not kept pace with the job demand of the growing population. LÄS MER

  7. 5. AI-Based Methods For Improved Testing of Radio Base Stations : A Case Study Towards Intelligent Manufacturing

    Författare :Cristina Landin; Amy Loutfi; Martin Längkvist; Sahar Tahvili; Brian Nielsen; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Sammanfattning : Testing of complex systems may often require the use of tailored-made solutions, expensive testing equipment, large computing capacity, and manual implementation work due to domain uniqueness. The aforementioned test resources are expensive and time-consuming, which makes them good candidates to optimize. LÄS MER
