  1. 1. Characterisation of Functional Pressing Die Surfaces

    Författare :Johan C Berglund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional correlation; functional surface; functional filtration; pressing die; multi-scale analysis; characterisation; finish milling; texture anisotropy; polishing; surface topography;

    Sammanfattning : The manufacture of dies and moulds is a critical aspect of many production systems since the manufacturing and try-out of new dies and moulds often is essential in determining the lead-time and quality of a new production system. In the automotive industry, many new car models are introduced each year and for each of these models, a new set of pressing dies has to be designed and manufactured. LÄS MER

  4. 3. Functional Aspects of the Juxtaglomerular Apparatus : Control of Glomerular Filtration and Renin Release

    Författare :Johan Sällström; Erik Persson; Peter Hansell; Jürgen Schnermann; Uppsala universitet; []
    Nyckelord :MEDICINE; MEDICIN; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : The juxtaglomerular apparatus (JGA) is a control unit of the kidney, that regulates glomerular filtration rate (GFR) and renin release, and hence extracellular volume and blood pressure. The tubuloglomerular feedback (TGF) mechanism is a negative feedback loop that regulates GFR. LÄS MER

  5. 4. Processing and characterization of membranes based on cellulose nanocrystals for water purification : Nanocellulose as functional entity

    Författare :Zoheb Karim; Marielle Henriksson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : Membrane technology is being extensively used in water purification as an energy efficient and low cost process. Nanostructured (NSM) and nanoenabled (NEM) membranes are favored in this context as nanoscaled entities are expected to provide high surface area, high mechanical properties and versatile surface chemistry as well as provide better control on the pore size and distribution, flux and selectivity of the membrane.

  7. 5. Versatile Implementations of an Improved Cell-Free System for Protein Biosynthesis : Functional and structural studies of ribosomal protein L11 and class II release factor RF3. Novel biotechnological approach for continuous protein biosynthesis

    Författare :Lamine Bouakaz; Måns Ehrenberg; Richard Buckingham; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Protein synthesis; translation termination; ribosome; release factor; cell-free system; missense error; gel filtration; affinity chromatography; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Sammanfattning : Advances in genetics, proteomics and chromatography techniques have enabled the successfully generation of a cell-free bacterial translation system composed of highly pure and active components. This system provided an ideal platform for better elucidating the mechanism of each individual step of the prokaryotic protein biosynthesis and the function of the translation factors involved in the process.
