1. 1. Atmosphere-ocean Interactions in Swell Dominated Wave Fields

   Författare :Alvaro Semedo; Anna Rutgersson; Oyvind Saetra; Piero Lionello; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Waves; Wind sea; Swell; Swell propagation; MABL; Air-sea interaction; Momentum flux; Wave climate; Coupling; Wave age; Empirical Orthogonal functions; Wave model; Climate model; WAM; RCA; wave heights; Meteorology; Meteorologi; Meteorologi; Meteorology;

   Sammanfattning : Ocean wind waves represent the atmosphere-ocean boundary, playing a central role in the air-sea exchanging processes. Heat, mass and momentum are transferred across this boundary, with waves mediating the exchange of principally the momentum between the winds and the ocean surface. During the generation process waves are called wind sea. LÄS MER

3. 2. Geotechnical Aspects of Buildings on Expansive Soils in Kibaha, Tanzania : Preliminary Study

   Författare :Charles Lucian; Staffan Hintze; Bo Berggren; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; expansive soils; soil properties; potential swell; Soil-Structure Interaction SSI ; and superstructure and substructure.; Building engineering; Byggnadsteknik;

   Sammanfattning : The focus of this study is on potential problems resulting from construction on expansive soils in Kibaha region, Tanzania. For the fact that most of the affected structures are founded on expansive soils, a clear understanding of the soil behaviour and their interaction with structures, specifically as they relate to shallow foundations, has been of more interest to the study in order to evaluate properly the source of the problem.

4. 3. Geotechnical Aspects of Buildings on Expansive Soils in Kibaha, Tanzania

   Författare :Charles Lucian; Staffan Hintze; Sven Knutsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Expansive soils; soil properties; potential swell; smectite montmorillonite ; multivariate statistics; geo-statistics; spatial variability; lightweight structures; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Sammanfattning :  The focus of this study is on potential damages to buildings resulting from expansive soils in Tanzania, particularly clay soils in Kibaha. For the fact that most of the affected structures are founded on expansive soils, a clear understanding of the behaviour of soils and their interaction with structures has been of interest to the study in order to evaluate properly the source of the problem.

5. 4. Influence of Pulp and Wood Properties on the Unreacted Residuals in Carboxymethyl Cellulose

   Författare :Kristina Jardeby; []
   Nyckelord :;

   Sammanfattning : In this work, the influence of pulp and wood properties on the amount and properties of unreacted residuals in carboxymethyl cellulose was evaluated. The results show that the presence of undissolved residuals in the CMC was not due to any chemical difference between these residuals and the reacted fibres. LÄS MER

7. 5. Water-swelling tablets based on hydrophobically modified poly(acrylic acid) - Effects of amphiphiles on swelling and drug release

   Författare :Patrik Knöös; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drug deliver; Controlled release; Hydrophobically modified polymers; Surfactant-polymer interactions; Poorly soluble drug;

   Sammanfattning : An important issue within the pharmaceutical world today is the increasing number of poorly soluble drugs. These often show a low bioavailability and a susceptibility to varying conditions in the intestine. LÄS MER
