1. 21. On Uncertainty and Data Worth in Decision Analysis for Contaminated Land

   Författare :Pär-Erik Back; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; uncertainty; decision analysis; risk; sampling; data worth; soil sampling; contaminated land;

   Sammanfattning : Contaminated soil and groundwater is a problem that has received increased attention in the last decade. Decision-making about investigation strategies, protective actions, and remedial actions is based on sparse and uncertain information, primarily data of contaminant concentrations and geological information.

3. 22. Computational Studies of Protein-ligand Systems Using Enhanced Sampling Methods

   Författare :Rongfeng Zou; Yaoquan Tu; Leif Eriksson; KTH; []
   Nyckelord :molecular dynamics; enhanced sampling; protein-ligand interactions; umbrella sampling; metadynamics; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

   Sammanfattning : This thesis focuses on studies of protein-ligand systems using enhanced sampling methods. In chapter I, I give a brief introduction to the time-scale problem and some enhanced sampling methods. In chapter II, the basics of MD simulation are reviewed. LÄS MER

4. 23. Chloride profiling in marine concrete - methods and tools for sampling

   Författare :Henrik Wall; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; klorider; betong; provtagning; concrete; sampling; chloride;

   Sammanfattning : This project focuses on how to determine the chloride content in concrete structures exposed to marine environment in an accurate way. When analyzing dust from dry drilling in concrete, it is very often a fact that the chloride profiles show extensive variations even if the sampling has been performed within a very concentrated area with the sampling points close to each other.

5. 24. Sampling from a suction induced mini-erosion in human skin. Methodological studies

   Författare :Christer Svedman; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vascular permeability; neurogenic inflammation; glucose; diabetes mellitus; interstitial fluid; transdermal; skin; sampling; Medicine human and vertebrates ; Medicin människa och djur ;

   Sammanfattning : Dermal interstitial fluid (IF) was extracted serially and painlessly by brief suction for as long as 6 days. The erosion was otherwise kept occluded, Sample volumes exceded those required for measuring a wide range of biological substances. Epidermal regeneration was rapid. LÄS MER

7. 25. An Experimental Study of a Liquid Steel Sampling Process

   Författare :Ola Ericsson; Andrey Karasev; Pär Jönsson; Lauri Holappa; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid steel sampling; inclusion characteristics; sampling conditions; sample homogeneity.; Metallurgical process engineering; Metallurgisk processteknik;

   Sammanfattning : During the steelmaking process samples are taken from the liquid steel, mainly to assess the chemical composition of the steel. Recently, methods for rapid determination of inclusion characteristics (size and composition) have progressed to the level where they can be implemented in process control. LÄS MER
