  1. 21. Systematic Design of Assembly Systems : Preconditions and Design Process Planning

    Författare :Monica Bellgran; Bengt Edgren; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Efficient assembly systems are necessary to the success of industrial companies where assembly is a strategic core activity. Each assembly system is the result of a unique design process where the available resources and options are utilised in order to suit the specific preconditions of the company and the situation.

  3. 22. Exploring Cancer Drugs In Vitro and In Vivo : With Special Reference to Chemosensitivity Testing and Early Clinical Development

    Författare :Anne von Heideman; Peter Nygren; Bengt Tholander; Rolf Larsson; Seija Grénman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytotoxic drug; in vitro assay; drug development; phase I clinical trial; Oncology; Onkologi; Oncology; Onkologi;

    Sammanfattning : The aims of this thesis were to investigate the utility of in vitro drug sensitivity testing to optimize the use of cancer chemotherapy and to assess the properties of a new cancer drug in a phase I clinical trial. Tumour cells from patients were analysed with the short-term Fluorometric Microculture Cytotoxicity Assay (FMCA). LÄS MER

  4. 23. Improving the Response of Saccharomyces cerevisiae to Lignocellulosic Hydrolysate Inhibitors in Ethanolic Fermentation

    Författare :Joao Almeida; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; furfural; ethanol; fermentation; phenolics; furaldehyde; HMF; ADH1; xylose reductase; tolerance; Saccharomyces cerevisiae; Lignocellulosic hydrolysate inhibitors; ADH6;

    Sammanfattning : The production of ethanol based on lignocellulosic biomass requires the fermentation of a hydrolysate containing hexose and pentose sugars in an inhibitory environment. In fact, the lignocellulosic hydrolysate obtained from pretreatment and hydrolysis of the raw material contains a variety of inhibitory compounds, including (i) the furaldehydes 5-hydroxymethyl-2-furaldehyde (HMF) and 2-furaldehyde (furfural), (ii) weak acids (e.

  5. 24. Assessing the toxic impact of chemicals using bacteria

    Författare :Jenny Gabrielson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Bacteria; toxicity testing; ecotoxicity; phylogenetic diversity; growth inhibition;

    Sammanfattning : There is a considerable backlog in the testing of new chemical compounds for their ecotoxic properties, mostly due to the lack of appropriate testing methods. In addition, there is a vivid debate today about the test endpoint for many of the existing methods. LÄS MER

  7. 25. Hedonic prices and center accessibility : conceptual foundations and an empirical hedonic study of the market for condominium housing in Singapore

    Författare :David E. Andersson; KTH; []
    Nyckelord :;

    Sammanfattning : One aim of this study is to compare and evaluateprespecified and data-specific functional forms for theestimation of hedonic price functions. One prespecifiedfunction and three types of data-specific Box-Cox functions areused to estimate hedonic price functions. LÄS MER
