  1. 1. Structural studies and design of Di-iron carboxylate proteins

    University dissertation from Stockholm : Stockholm University

    Author : Martin Andersson; Martin Bollinger Jr; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Abstract : Di-iron carboxylate proteins perform a wide range of chemical reactions in the cell. These reactions often involve activation of dioxygen to generate highly oxidative species that can be used in catalysis. One member of the di-iron carboxylate family is the enzyme ribonucleotide reductase (RNR). READ MORE

  4. 4. Process analytical methods for monitoring of the film coating on pharmaceutical pellets and tablets using NIR spectrometry and image analysis

    University dissertation from Martin Andersson, Technical Analytical Chemistry, Lund University, P.O.Box 124, S-221 00 Lund, Sweden

    Author : Martin Andersson; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PLS; PCA; PAC; NIR; chemometrics; moving samples; information depth; release rate; image analysis; near infrared; process analytical chemistry; thickness; coating; film; tablets; Pellets; granules; Analytical chemistry; Analytisk kemi;

    Abstract : Pharmaceutical tablets and pellets are often covered with a coating. There is a need for methods that enable monitoring of the growth of such films during processing. Such analyses can be performed using process analytical chemical methods based on near infrared (NIR) diffuse reflectance spectrometry. It provides with analyses that take only ca. READ MORE

  5. 5. An experimental investigation of spur gear efficiency and temperature A comparison between ground and superfinished surfaces

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Martin Andersson; Ulf Olofsson; Bengt-Göran Rosén; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gears; ground; superfinished; efficiency; temperature; running-in; dip lubrication; spray lubrication; Machine Design; Maskinkonstruktion;

    Abstract : This thesis focuses on reliability when testing gear efficiency and on how gear mesh efficiency can be increased without detrimental effects on the gears. Test equipment commonly used in gear research was analysed to identify important parameters for gear efficiency testing. READ MORE
