3. 2. On Caries Risk Profiles Using Cariogram and Caries Prevention with Fluoridated Toothpaste in Orthodontic Patients

   Författare :Anas H Al Mulla; Dowen Birkhed; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caries lesions. Caries model. Caries risk. Cariogram. QLF. Orthodontic bands. Saudi Arabia. Slurry rinsing. Toothbrushing. Toothpaste. Toothpaste technique. Water rinsin;

   Sammanfattning : Objective. The aims of this thesis were to: 1) analyse caries-related factors shortly after orthodontic treatment, 2) demonstrate the usefulness of the Cariogram by presenting orthodontic patients with different caries-risk profiles, 3) compare two different toothpastes with different post brushing techniques using an in situ caries model with orthodontic bands, and 4) test the hypothesis that toothpaste slurry rinsing, combined with some other simple post-brushing advice (in this thesis called the “modified F toothpaste technique, MFTT“), would reduce the number of decayed and filled tooth surfaces (DFS) in a 2-year randomised clinical trial in orthodontic patients.

4. 3. Loss Minimisation in Dynamic Food Processes

   Författare :Marcus Henningsson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Teknik; Technological sciences; CFD; dual plane ERT; ERT; waste minimisation; loss; milk; density; sensor fusion; multivariate calibration; electrical resistance tomography; dairy process; turbidity; conductivity;

   Sammanfattning : The overall aim of the present work was to reduce losses during product changes or during rinsing in continuous food processing, with particular attention to dairy plants. The concept of sensor fusion of common process instruments was implemented as a tool to monitor the milk and fat concentrations in a dairy processing line. LÄS MER

5. 4. Preparation, characterisation and wetting of fluorinated cellulose surfaces

   Författare :Christian Aulin; Lars Wågberg; Sigbritt Karlsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Sammanfattning : This thesis deals with the wetting by oil mixtures of two different model cellulose surfaces. The surfaces studied were a regenerated cellulose (RG) surface prepared by spin-coating, and a film consisting of polyelectrolyte multilayers (PEM) of Poly(ethyleneimine) (PEI) and a carboxymethylated Microfibrillated Cellulose (MFC).

7. 5. Investigations on Membrane Fouling and Cleaning in Ultrafiltration Processes in Lignocellulosic Biorefineries

   Författare :Gregor Rudolph; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane fouling; Membrane cleaning; Ultrafiltration; Online monitoring; Galactoglucomannan; Wood extractives; QCM-D; Lignocellulosic biomass; pulp and paper;

   Sammanfattning : The current fossil-based economy must be transformed into a bio-based circular economy. A cornerstone of this transformation is the conversion of pulp and paper mills into lignocellulosic biorefineries that allow not only the production of pulp, paper, and electricity, but also novel biochemicals.
