  1. 1. Inductively Coupled Plasma Spectrometry for Speciation Analysis : Development and Applications

    Författare :Niklas Forsgard; Jean Pettersson; Marit Andersson; Jonas Bergquist; Walter Lund; Uppsala universitet; []
    Nyckelord :Analytical chemistry; Speciation analysis; Atomic emission spectrometry AES ; Mass spectrometry MS ; Inductively coupled plasma ICP ; Liquid Chromatography LC ; on-line sample pre-treatment; Organic phosphour; Siderophores; Slurry nebulization; matrix effects; Analytisk kemi;

    Sammanfattning : In analytical chemistry the main goal is normally to determine the identity and/or concentration of one or more species in a sample. The samples analyzed are often natural samples, containing numerous different species in a complex matrix and the choice of technique for multi-elemental detection is in general inductively coupled plasma spectrometry.

  3. 2. Shear Fracture and Delamination in Packaging Materials : A study of Experimental Methods and Simulation Techniques

    Författare :Md. Shafiqul Islam; Sharon Kao-Walter; Christian Johansson; Johan Tryding; Blekinge Institute of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Package opening; Shear test specimen; Stress intensity factor; Finite Element simulation; Scanning electron microscopy; Polymers; Interlaminar shear delamination;

    Sammanfattning : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. Package opening is becoming complicated in many cases because of cutting cost in design and production of opening techniques. LÄS MER

  4. 3. Kulturgeografin tar plats i välfärdsstaten : Vetenskapliga modeller och politiska reformer under efterkrigstidens första decennier

    Författare :Pär Wikman; Per Lundin; Niklas Stenlås; Magnus Eklund; David Larsson Heidenblad; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Postwar social science; history of geography; history of planning; central place theory; Torsten Hägerstrand; municipal reforms; reform technocrats;

    Sammanfattning : The aim of this study is to explain why human geography in Sweden became a planning science during the postwar period. Human geography had developed a sophisticated use of abstract models. The proliferation of models within in the social sciences was an international phenomenon during the postwar period. LÄS MER
