2. 1. Chloride initiated reinforcement corrosion in marine concrete

   Author : Paul Sandberg; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; w c ratio; cover thickness; chloride penetration; service life prediction; corrosion cells; chloride thresholds; field exposure tests; marine concrete; pozzolans; reinforcement corrosion; chloride binding; Building construction; Byggnadsteknik;

   Abstract : Factors affecting the total chloride threshold for initiation of pitting corrosion in reinforced concrete were investigated by means of field and laboratory exposure tests. Factors affecting the chloride penetration into concrete were also investigated by means of field tests. The thesis consists of a summary (86 p.) and 11 papers attached. READ MORE

4. 2. Colour – A Reliable Quality-Control Tool for Industrial Thermowood® Production

   Author : Petteri Torniainen; Dennis Jones; Olov Karlsson; Dick Sandberg; Henrik Veikko Juhani Heräjärvi; Luleå tekniska universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Thermally-modified timber; Thermo-S; Thermo-D; colour Lab; Scots pine; Pinus sylvestris; Norway spruce; Picea abies; quality control; Träteknik; Wood Science and Engineering;

   Abstract : The objective of the work presented in this doctoral thesis has been to correlate the commercial output of  ThermoWood® process with a pre-defined, quantifiable, non-destructive measurable parameter - colour, and to show the feasibility of measurements to be the essential part of the internal and external quality-control system. Colour is the most evident property changed of thermally-modified timber (TMT). READ MORE

5. 3. Novel Approaches to ECG-Based Modeling and Characterization of Atrial Fibrillation

   Author : Frida Sandberg; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HMM; ECG; Biomedical Signal Processing; Time-Frequency Analysis; Atrial Fibrillation; Sample Entropy; AV modeling;

   Abstract : This thesis deals with signal processing algorithms for analysis of the electrocardiogram (ECG) during atrial fibrillation (AF). Such analysis can be used for diagnosing patients, and for monitoring and predicting their response to various treatment. READ MORE

6. 4. Management of dental clinics by the use of informatics

   Author : Hans Sandberg; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Management; dental; informatics; computerized; prevention; health; prevention;

   Abstract : The main objective with this project has been to develop a tool for close to-the-clinic healthcare management, based upon ways of measuring which are interpretable both by professionals as well as by patients. This would be a tool that collects and compiles data related to the dental health situation, permitting an overview of a dental clinic, and thus facilitating the management of dental-health improvements.

7. 5. Growth factor regulation of the urokinase plasminogen activator (uPA) system in human endometrium, and the significance of uPA receptor activation in endometrial angiogenesis

   Author : Tove Sandberg; Lund Obstetrik och gynekologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics; endothelial cell migration; angiogenesis; uPA:PAI-1 complex; uPAR; TGF-beta; PAI-1; EGF; uPA; Growth factor; gynaecology; andrology; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

   Abstract : The purpose of this thesis was to examine the role of growth factors and the urokinase plasminogen activator (uPA) system in human endometrial angiogenesis. Growth factors as well as progesterone increased expression of the main inhibitor of uPA (PAI-1) in primary cultures of endometrial stromal cells. READ MORE
