1. 1. Conversational Writing : A Multidimensional Study of Synchronous and Supersynchronous Computer-Mediated Communication

   Författare :Ewa Jonsson; Uppsala universitet; []
   Nyckelord :HUMANITIES; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; HUMANIORA; CMC; computer-mediated communication; conversational writing; chat; computer chat; ICQ; IRC; Internet relay chat; multidimensional; Biber’s dimensions; synchronous CMC; supersynchronous CMC; English; Engelska;

   Sammanfattning : This study is a linguistic investigation of two genres of computer-mediated communication (CMC), namely two modes of conversational writing: ‘Internet relay chat’ (synchronous CMC) and ‘split-window ICQ chat’ (supersynchronous CMC). The study employs Douglas Biber’s multifeature multidimensional methodology, taking into account the six dimensions of textual variation in English identified in his 1988 book Variation across speech and writing (i.

3. 2. A Linguistic Analysis of Peer-review Critique in Four Modes of Computer-mediated Communication

   Författare :Irina Frisk; Terry Walker; Mats Deutschmann; Philip Shaw; Mittuniversitetet; []
   Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; CMC; Conversation Analysis; conversation management; discussion boards; feedback category; mode of CMC; peer-review discussion; politeness theory; pragmatic strategy; speech act of critique; text-based chat; type of politeness; voice-based chat; VoiceThread;

   Sammanfattning : Abstract The present work is a quantitative and qualitative analysis of pragmatic strategies for delivering critique, and types of politeness, used by undergraduate L2 students of English at different stages of peer-review discussion. The material examined consists of four corpora of authentic conversations between students, the main purpose of which was to give feedback on each other’s contributions during an English A-level course, at Mid-Sweden University.

4. 3. Wood Hydrolysate for Renewable Products

   Författare :Yingzhi Zhu Ryberg; Ulrica Edlund; Ann-Christine Albertsson; Ann Cornell; Louise Staffas; KTH; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

5. 4. Mathematical Modeling of Turbulent Reactive Flows

   Författare :Mikael Mortensen; Chalmers University of Technology; []
   Nyckelord :PMF; CFD; probability density function; chemical reactions; presumed mapping function; PDF; conditional moment closure; turbulent mixing; computational fluid dynamics; CMC;

   Sammanfattning : The purpose of this thesis has been to study and develop mathematical models of non-premixed turbulent reacting flows. The models developed can be used both by the chemical process industry and for turbulent combustion applications. Furthermore, the models are general and not developed for any specific chemical or mechanical system. LÄS MER

7. 5. Wood hydrolysates- New concepts in renewable material design

   Författare :Yingzhi Zhu Ryberg; Ulrica Edlund; Ann-Christine Albertsson; Dufresne Alain; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood hydrolysate; oxygen barrier; coatings; films; hemicellulose; lignin; CMC; chitosan; HSP; PALS; spray drying; SEM with tensile test; glyoxal crosslinking.; vedhydrolysat; syrebarriäregenskaper; ytbeläggningar; filmer; hemicellulosa; lignin; CMC; kitosan; HSP; PALS; spraytorkning; SEM med dragprovning; glyoxal tvärbindning.;

   Sammanfattning : Wood hydrolysates (WHs) are biomasses obtained in processes involving hydrothermal treatments of wood. WHs are rich in hemicelluloses and lignin. Instead of complicated extraction processes, such as precipitation, or extensive purification, this work utilizes the crude WHs. LÄS MER
