1. 21. Predicting oral performance of lipid-based formulations using in vitro methods

   Författare :Oliver Hedge; Christel Bergström; Frédéric Carriere; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lipid-based formulation s ; SEDDS; artificial membrane s ; cell monolayer s ; oral drug delivery; lipolysis; permeation; Farmaceutisk vetenskap; Pharmaceutical Science;

   Sammanfattning : Oral administration of drugs is widely considered preferable to other methods by end-users and healthcare providers alike; however, not all drug compounds are inherently suited for it because some molecules are not well-absorbed by the intestine. Good absorption requires both dissolution and permeation. LÄS MER

3. 22. Molecular-level Simulations of Cellulose Dissolution by Steam and SC-CO2 Explosion

   Författare :Faranak Bazooyar; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; molecular modelling; cellulose; steam explosion; SC-CO2 explosion; Resource Recovery; Resource Recovery; Resursåtervinning;

   Sammanfattning : Dissolution of cellulose is an important but complicated step in biofuel production from lignocellulosic materials. Steam and supercritical carbon dioxide (SC-CO2) explosion are two effective methods for dissolution of some lignocellulosic materials. Loading and explosion are the major processes of these methods.

4. 23. Organiserande och kvalitetsutveckling : Om sönderfall, upprätthållande och begripliggörande i arbetslivet

   Författare :Robert Holmberg; Institutionen för psykologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; participation; dialogue; narrative; sensemaking; Organizing; total quality management; Psykologi;

   Sammanfattning : The study explores the interaction of general management ideas like TQM (here referred to as technocratic visions) and microprocesses of narrating and organizing in two different contexts: the public sector (health care) and the private sector (manufacturing) in Sweden. The purpose is to provide a better understanding of what happens when models of this type are introduced into a work organization. LÄS MER

5. 24. New single particle methods for detection and characterization of nanoparticles in environmental samples

   Författare :Jani Tuoriniemi; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Detection; Quantification; Metrology; Trace particle;

   Sammanfattning : Nanoparticles (NP) are being used in rapidly increasing quantities which has resulted in concerns about possible harmful effects for health and environment. NP are already undergoing similar risk assessment programs as conventional chemicals, and due to their enhanced surface reactivities it has been proposed that the use of NP should be regulated by specific legislation based on particle size.

7. 25. DissolvIt : development and validation of a new in vitro dissolution apparatus for dry powder aerosols

   Författare :Maria Malmlöf; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Today there are no recommended dissolution methods for use in the development of new inhalable drugs. In the absence of such tailored methods, standard dissolution test methods from oral- or skin administration routes are used instead. Such methods are obviously not designed to resemble the lung environment. LÄS MER
