1. 1. Stabilisering av torv : olika faktorers inverkan på stabiliseringseffekten

   Författare :Kerstin Pousette; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

   Sammanfattning : Torvmarker är sättningskänsliga och ej lämpliga att bygga på. Om en väg eller järnväg ska byggas över torvmark måste åtgärder vidtas för att förstärka undergrunden. En metod som har börjat användas de senaste åren är masstabilisering, där ett stabiliseringsmedel blandas ner i torven för att öka dess hållfasthet. LÄS MER

3. 2. A Chemometric Approach to Process Monitoring and Control - With Applications to Wastewater Treatment Operation

   Författare :Christian Rosén; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Elektroteknik; Electrical engineering; wastewater treatment; supervisory control; simulation; process monitoring; principal component analysis PCA ; multivariate statistics; modelling; activated sludge; detection; control engineering; Automatiska system; robotteknik; reglerteknik; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : In this work, various aspects of multivariate monitoring and control of wastewater treatment operation are discussed. A number of important difficulties face operators and process engineers when handling online measurements from wastewater treatment processes. LÄS MER

4. 3. Long Term Outcome and Prediction Models of Cognition, Activities of Daily Living and Nursing Home Placement in Alzheimer’s Disease with Cholinesterase Inhibitor Treatment

   Författare :Carina Wattmo; Klinisk minnesforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; longitudinal studies; nursing home placement; activities of daily living; cognition; Alzheimer s disease; cholinesterase inhibitors; disease progression; predictors; statistical models.;

   Sammanfattning : Background Prospective longitudinal studies in Alzheimer's disease (AD) that include cholinesterase inhibitor (ChEI) treatment in routine clinical settings are scarce. The patients vary in severity of the disease, clinical course, rate of progression and response to treatment. LÄS MER

5. 4. Bacterioplankton population dynamics in a changing ocean

   Författare :Markus V. Lindh; Jarone Pinhassi; Pierre Galand; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marine microbiology; ecology; bacterioplankton; community composition; diversity; seasonality; biogeography; bimodal; metapopulation; community functioning; climate change; environmental disturbance;

   Sammanfattning : Bacterioplankton is characterized by high diversity, short generation times and rapid turnover. Despite their small size, these numerous microorganisms are a fundamental piece of aquatic ecosystems by channeling carbon to higher trophic levels through dissolved organic matter utilization.

7. 5. Adsorption of proteins on zeolite FAU

   Författare :Daniel Klint; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; matrix preparation; cryo-electron microscopy; protein purification; zeolites; Inorganic chemistry; Oorganisk kemi;

   Sammanfattning : A highly dealuminated form of zeolite FAU, ultra-stable zeolite Y (USY), was used as an adsorbent matrix in the purification of proteins. Undesired proteins were removed from a crude preparation by adsorption on USY, increasing the purity of an unadsorbed protein (horse radish peroxidase), or the protein of interest was adsorbed on the zeolite and subsequently eluted through changes in the solution conditions (hen egg lysozyme, mouse-immunoglobulin G).
