2. 1. New Mass Spectrometric Methods for Structure Analysis of Carboxymethyl Cellulose

   Author : Jonas Enebro; Sigbritt Karlsson; Dane Momcilovic; Ulf Germgård; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; carboxymethyl cellulose; substituent distribution; rheology; enzyme hydrolysis; cellulase; permethylation; liquid chromatography; MALDI; ESI; mass spectrometry; Polymer chemistry; Polymerkemi;

   Abstract : Carboxymethyl cellulose (CMC) is a cellulose derivative, made from cellulose by introduction of carboxymethyl groups along the molecules. The properties of CMC are affected by several parameters where the molar mass and molar mass distribution, degree of substitution (DS) and the distribution pattern along, and between, the cellulose molecules are the most prominent.

4. 2. On Evaluation and Modelling of Human Exposure to Vibration and Shock on Planing High-Speed Craft

   Author : Katrin Olausson; Karl Garme; Jakob Kuttenkeuler; Dominic J. Taunton; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; whole-body vibration; high-speed craft; working conditions; seat modelling; apparent mass; ergonomics; human factors; ISO 2631-1; ISO 2631-5; extreme values; acceleration statistics; slamming;

   Abstract : High speed in waves, necessary in for instance rescue or military operations, often result in severe loading on both the craft and the crew. To maximize the performance of the high-speed craft (HSC) system that the craft and crew constitute, balance between these loads is essential. READ MORE

5. 3. Amino acids with relevance to health, climate and the environment : Development of mass spectrometric methods

   Author : Javier Zurita; Leopold Ilag; Ulrika Nilsson; Margareta Törnqvist; Natalia Tretyakova; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; amino acids; LC MS; fixed-charge derivatization; BMAA; chiral separation; pheromones; arctic aerosols; serum albumin adducts; benzo[a]pyrene diol epoxides; high-resolution MS; Analytical Chemistry; analytisk kemi;

   Abstract : Amino acids play vital roles in health, either in their native form or chemically modified. Some studies have linked certain non-proteinogenic amino acids to neurodegenerative diseases, such as in the case of β-methylaminoalanine (BMAA). READ MORE

6. 4. Listening to the story of the rock mass : The integration of conventional and unconventional data to understand rock mass behaviour at the Kiirunavaara Mine

   Author : Jessica Vatcher; Stephen D McKinnon; Jonny Sjöberg; Dick Stacey; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

   Abstract : The need to understand rock mass behaviour has never been greater; as mining globally progresses deeper to extract the precious resources humankind needs to maintain and forward our lives, we encounter rock behaviours associated with deep mining. These environments typically experience seismicity (including fault slip), rock bursting, strain bursting, spalling, aseismic movement along pre-existing discontinuities, and ground falls. READ MORE

7. 5. Critical potential and oxygen evolution of the chlorate anode

   Author : Linda Nylén; Göran Lindbergh; Yohannes Kiros; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chlorate; chloride oxidation; oxygen evolution; critical anode potential; chromate; DSA; mass transport; RDE; Chemical engineering; Kemiteknik;

   Abstract : In the chlorate process, natural convection arises thanks to the hydrogen evolving cathode. This increases the mass transport of the different species in the chlorate electrolyte. There is a strong connection between mass transport and the kinetics of the electrode reactions. READ MORE
