1. 1. Film och historia. Historisk Hollywoodfilm 1960-2000

   Författare :Mats Jönsson; Filmvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; Film and history; palimpsest of historical consciousness; historical thinking vs History with a capital H; conventional markers; authorship; matrix; Hollywood; 1960-2000.; History; Historia;

   Sammanfattning : The hypothesis put forward in this thesis stipulates that films always say more of empirical value about the time in which they are produced than they do about the periods they depict. The aim is not only to prove that such an idea is valid, but also that it might be transformed into a new and applicable theory in studies of film and history. LÄS MER

3. 2. Modelling of Drug Release from Reservoir and Matrix Formulations - Multiple Unit Dosage Forms and Swelling and Dissolving Matrix Systems

   Författare :Per Borgquist; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swelling; XEDS; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Polymer technology; biopolymers; Polymerteknik; Pharmaceutical and related technologies; Läkemedelsteknik och relaterad teknik; simulation; single pellet; single-unit release; SEM; reservoir system; poly ethylene oxide ; film-coated; matrix; mathematical model; diffusion; pellet shape; controlled release; polymer dissolution; modelling; ethyl cellulose; Coating; multiple-unit release;

   Sammanfattning : In this work, mathematical models have been developed describing drug release from film-coated reservoir systems as well as drug release and polymer dissolution from swelling and dissolving polymer tablets. The model derivation of both systems is based on a mechanistic approach. The model describing drug release from reservoir systems, i.e. LÄS MER

4. 3. Crystallinity and Morphology of Starch Polymers in Films

   Författare :Åsa Rindlav Westling; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; morphology; amylose; surface; thermal transitions; amylopectin; starch; crystallinity; film;

   Sammanfattning : Starch is a renewable material that can be converted into biodegradable plastic products, or films with excellent oxygen barrier properties. Films of potato starch, amylose, amylopectin and blends thereof were made by solution casting. LÄS MER

5. 4. Biocomposites Based on Core-Shell Cellulose Nanofibers : Preparation, Structure, and Properties

   Författare :Kasinee Prakobna; Lars Berglund; David Plackett; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; cellulose nanofibers; polysaccharides; holocellulose; nanostructure; dispersion; mechanical properties; hygromechanical properties; moisture stability; film; porous material; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : Cellulose nanofibers (CNFs) are of interest as load-bearing components for polymer matrix nanocomposites. A wide range of nanostructured materials including nanopaper/films, foams, aerogels, and hydrogels can be prepared from CNFs. The material performance can be fine-tuned when CNFs are combined with different polymer matrices. LÄS MER

7. 5. Wood Hydrolysate for Renewable Products

   Författare :Yingzhi Zhu Ryberg; Ulrica Edlund; Ann-Christine Albertsson; Ann Cornell; Louise Staffas; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wood hydrolysate; hemicellulose; oxygen permeability; PALS; film; coating; CMC; chitosan; HSP; Polymer chemistry; Polymerkemi;

   Sammanfattning : Renewable biomass has been used by mankind for a long time for different purposes, from simply food to industrial products. Among a large family of polysaccharides, hemicellulose is non-edible but has shown a potential in many industrial fields such as medicine, agriculture and packaging. LÄS MER
