2. 1. Baltic Sea Ports and Russian Foreign Trade - Studies in the Economic and Political Geography of Transition

   Author : Alf Brodin; Göteborgs universitet; []
   Keywords : Hamnar; transition; Östersjön; transportgeografi; geopolitik; Ryssland; Estland; Lettland; Litauen; Baltikum; fd. Sovjetunionen; handelsstatistik; transithandel; Port; transition; Baltic Sea; transport geography; geopolitics; Russia; Estonia; Latvia; Lithuania; former Soviet Union; transit trade; trade statistics;

   Abstract : The aim of this study is to describe how the changing geopolitical environment in the former Soviet Union (FSU) has created a new transport geography, and thereby resulted in new patterns of foreign trade routes, port competition and market economic adaptation in the Baltic Sea fringe. The geographical limitation is the western part of the FSU and the Baltic Sea. READ MORE

4. 2. Digital twinning for ports : from characterization to operations’ modelling

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

   Abstract : 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.

5. 3. Hormonal regulation of phosphodiesterase 3B in adipocytes

   Author : Rebecka Lindh; Signaltransduktionsforskning; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; secreting systems; diabetology; Endokrinologi; Endocrinology; caveolae localization ; phosphorylation interactions ; PDE3B adipocyte adipose tissue diabetes cAMP insulin ; lipolysis caveolin-1 ; sekretion; diabetologi;

   Abstract : Insulin induced activation of the cAMP degrading enzyme phosphodiesterase (PDE) 3B in adipocytes is important for insulin mediated inhibition of lipolysis. The aim of this thesis was to contribute with knowledge on the acute activation of PDE3B in response to insulin and catecholamines in adipocytes. READ MORE

6. 4. Traces of Mathematical Facts and Students’ Understanding of the Concept `Quadrilateral´ : An enquiry into young students’ communication

   Author : Eva Juhlin; Maria Johansson; Ewa Bergqvist; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematics Education; Matematik och lärande;

   Abstract : Mathematics could be described as a special kind of language, a discourse in which participants communicate abstract concepts. Communication and language are known to be important factors in teaching and learning but little is known about neither communication between students in relation to geometrical concepts, nor what traces of mathematical facts and understanding is incorporated into their communication.

7. 5. Mesoporous Silica SBA-15 - Formation, Modification and Application

   Author : Tomas Kjellman; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SBA-15; Mesoporous Silica; Intrawall pores; Colloidal Stability; Drug release; Deposition;

   Abstract : Several aspects related to the mesoporous silica material SBA-15 have been studied through the use of a wide range of experimental techniques, including low voltage high-resolution scanning electron microscopy, small angle X-ray scattering and nitrogen sorption. This work contains three parts, which are in many ways overlapping. READ MORE
