  2. 1. Light Propagation and Gas Absorption Studies in Turbid Media Using Tunable Diode Llaser Techniques

    Author : Liang Mei; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gas in scattering media absorption spectroscopy; tunable diode laser absorption spectroscopy; frequency modulated light scattering interferometry; light propagation; Absorption spectroscopy; turbid media; diode laser; gas monitoring; porous media; ceramics; food packaging; Fysicumarkivet A:2014:Mei;

    Abstract : Optical absorption spectroscopy is a widely used analytical tool for constituent analysis in many applications. According to the Beer-Lambert law, the transmitted light intensity through a homogeneous medium is an exponential function of the product of the concentration, the total pathlength, and the absorption cross-section of the absorbing substance.

  4. 2. On two methods for identifying dynamic errors-in-variables systems

    Author : Mei Hong; Torsten Söderström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

    Abstract : Identification of dynamic errors-in-variables systems, where both inputs and outputs are affected by errors (measurement noises), is a fundamental problem of great interest in many areas, such as process control, econometrics, astronomical data reduction, image processing, etc. This field has received increased attention within several decades.

  5. 3. Functional role of cytoskeletal, contractile and regulatory proteins in muscle disease

    Author : Mei Li; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The function of skeletal muscle is an essential component of animal physiology and daily life. Hereditary muscle diseases are comparatively rare in humans, but often very severe. The disease causes are heterogeneous, defects in nerves, intracellular components, structural proteins and the contractile apparatus can be involved. READ MORE

  6. 4. Transformation/dissolution characteristics of cobalt and welding fume nanoparticles in physiological and environmental media: surface interactions and trophic transfer

    Author : Nanxuan Mei; Eva Blomberg; Inger Odnevall Wallinder; Jonas Hedberg; Iseult Lynch; KTH; []
    Keywords : nanoparticles; cobalt; stainless steel welding fume particles; biomolecules; metal release; trophic transfer; adsorption; agglomeration; algae; nanopartiklar; kobolt; rostfritt stål svetsrök partiklar; biomolekyler; metallfrigöring; trofisk överföring; adsorption; agglomerering; alger; Kemi; Chemistry;

    Abstract : Nanoparticles (NPs) and nanomaterials (NMs) are present everywhere in the environment. They can form both as an act of nature and during human activities. Various kinds of NPs and NMs are engineered for different applications in the ongoing development of nanoscience and technology. READ MORE

  7. 5. Characterization of the Intestinal Microbiota by DNA-Based Methods

    Author : Mei Wang; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; bacteriology; virology; Microbiology; Ulcerative colitis; T-RFLP; 16S rRNA; Brachyspira; Microbiota; Bacterial diversity; Bacterial translocation; Translocating bacteria;

    Abstract : The intestinal flora and the bacteria found in the extraintestinal sites were studied in liver injury rats, with or without Lactobacillus plantarum 299v pre-treatment. The dominating intestinal flora and translocating bacteria were typed by RAPD and identified by 16S rDNA sequencing. READ MORE
