    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; analytical methods; HPLC high-performance liquid chromatography ; miniaturization; in vitro dissolution rate; apparent solubility; physicochemical properties; dissolution media; correlation study; chemometrics; Pharmaceutical chemistry; Farmaceutisk kemi; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Abstract : The general aim of this thesis was to evaluate a newly designed and constructed miniaturized rotating disk apparatus for in vitro dissolution rate measurements of different drug substances from all of the classes in the Biopharmaceutical Classification System (BCS). The new equipment is based on a low volume flow-through cell of Plexiglas, a gold plated magnetic bar and a special designed press. READ MORE

  4. 12. Analytical method development for ultra-trace determination of human pharmaceuticals in aqueous samples. Assessing the performance of a sewage treatment plant

    Author : Saioa Zorita; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecularly imprinted solid-phase extraction; Sample preparation; solid-phase extraction; membrane extraction; human pharmaceuticals; sewage treatment plant; steroid hormones;

    Abstract : Research focus in environmental pollution has recently been extended from more classical environmental pollutants such as PCBs or pesticides to pharmaceuticals and steroid hormones, which are designed to be biologically active and enter the environment primarily through regular domestic use. Consequently, it is important to monitor these substances concentrations in the effluents of sewage treatment plants (STPs) and in the environment in order to evaluate their associated risks.

  5. 13. Essays on Labor Economics : The Role of Government in Labor Supply Choices

    Author : Niklas Blomqvist; Peter Skogman Thoursie; Martin Olsson; Björn Tyrefors; Spencer Bastani; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Involuntary Part-time Employment; Labor Supply; Tax Elasticity; Refugees; Immigration; Integration; Natural Resource Extraction; Family Resources; Health; Economics; nationalekonomi;

    Abstract : "Right to Work Full-time" Policies and Involuntary Part-time EmploymentThis paper investigates the effect of right to full-time policies implemented to decrease involuntary part-time work for public care workers employed by Swedish municipalities. Taking advantage of a staggered decision process, these policies are evaluated using a difference-in-differences approach. READ MORE

  6. 14. Characterization of neuropeptide, monoamine, and amino acid release in the basal ganglia of the rat : neuronal dependence and reciprocal interactions

    Author : Zhi-Bing You; Karolinska Institutet; Karolinska Institutet; []
    Keywords : amino acids cholecystokinin dopamine dynorphin microdialysis morphineneostriatum rat substantia nigra.;

    Abstract : Functional interactions in the basal ganglia of rats were characterized with in vivomicrodialysis. The study was mainly focused on the dynorphin and cholecystokinin (CCK) systems. The extracellular levels of both dynorphin B and CCK were found in the pM range inthe neostriatum and substantia nigra under basal conditions. READ MORE
