    Sammanfattning : Living matter is built on complex dynamic systems consisting of numerus biotransformations. By exploiting the adaptive and evolutive behaviors ofmolecular matter, dynamic chemistry has developed as an important tool tounderstand the organization of nonliving matter into complex living systems.

  3. 2. Clostridium difficile : epidemiology and antibiotic resistance

    Författare :Torbjörn Norén; Erik Bäck; Lars G. Burman; Roland Möllby; Örebro universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Clostridium difficile; antibiotic resistance; epidemiology; Medicine; Medicin; Medicin; Medicine;

    Sammanfattning : Clostridium difficile is a spore-forming toxin-producing intestinal bacterium abundant in soils and waters. This pathogen relies on increased growth by a disturbed intestinal microflora and the production of two cytotoxins, toxin A and toxin B, which may cause anything from mild self-limiting C. LÄS MER

  4. 3. Statistical Mechanical Studies of Titrating Polyelectrolytes

    Författare :Magnus Ullner; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; integral equation theory; variational calculations; Monte Carlo simulations; end-to-end separation; apparent dissociation constant; titrating polyelectrolytes; electrostatic interactions; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Different models and statistical mechanical approximations for titrating polyelectrolytes are studied and the results compared with Monte Carlo simulations and experimental data. Three types of models have been used in the simulations: i) rigid structures and freely jointed chains with ii) rigid bonds and iii) flexible, harmonic bonds. LÄS MER

  5. 4. Tailored Reaction Media for the Synthesis of Subvalent Cluster Compounds

    Författare :Josefin Åkerstedt; Lars Kloo; Sven Lidin; Ulf Gedde; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Inorganic Chemistry;

    Sammanfattning : Different synthetic approaches and modifications to reaction media have been applied in order to find new routes to the synthesis of main-group clusters and transition metal compounds. The focus has been on the Group 15 element bismuth and the transition metal palladium. LÄS MER

  7. 5. Carrot Juice Processing - Effects on Various Quality Aspects

    Författare :Charlotte Alklint; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modified atmosphere; shelf-life; accelerated storage; isothermal calorimetry; pressing; expression method; colour; dietary fibre; carotene; composition; carrot pomace; carrot juice; carrot pulp; acidification; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : Carrots are a cold-weather crop well suited for cultivation in the south of Sweden. Carrots are generally rather inexpensive, with a market price below € 1 /kg (Sweden, 2003), whereas fresh carrot juice has a price of around € 5 /kg. LÄS MER
