  1. 1. Influenza neuraminidase assembly : Evolution of domain cooperativity

    Author : Diogo da Silveira Vieira da Silva; Robert Daniels; Ron Fouchier; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Influenza; neuraminidase; assembly; transmembrane domain; evolution; biokemi; Biochemistry;

    Abstract : Influenza A virus (IAV) is one of the most common viruses circulating in the human population and is responsible for seasonal epidemics that affect millions of individuals worldwide. The need to develop new drugs and vaccines against IAVs led scientists to study the main IAV surface antigens hemagglutinin (HA) and neuraminidase (NA). READ MORE

  2. 2. On the Low Frequency Noise in Ion Sensing

    Author : Da Zhang; Zhen Zhang; Shili Zhang; Hans Norström; Jörgen Olsson; Michel Calame; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; low frequency noise; ion sensor; ISFET; electrochemical impedance spectroscopy; constant phase element; surface chemistry; CMOS technology; Engineering Science; Teknisk fysik;

    Abstract : Ion sensing represents a grand research challenge. It finds a vast variety of applications in, e.g., gas sensing for domestic gases and ion detection in electrolytes for chemical-biological-medical monitoring. READ MORE

  3. 3. Evaluation of locally available feed resources for striped catfish (Pangasianodon hypophthalmus)

    Author : Chau Thi Da; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Abstract : This thesis investigated and compared inputs and outputs, economic factors and current feed use in small-scale farming systems producing striped catfish (Pangasianodon hypophthalmus) in the Mekong Delta. The nutrient content of locally available natural feed resources for striped catfish was determined and growth performance, feed utilisation and body indices were analysed in pond-cultured striped catfish fed diets where fish meal protein was replaced with protein from local feed resources.

  4. 4. Aspects of N-glycosylation in human IgE

    Author : Johanna Da Luz; Karolinska Institutet; Karolinska Institutet; []

    Abstract : The medical interest of allergy in industrialised societies has generated a much greater knowledge about the pathophysiology of IgE-mediated responses than about its normal physiological role. Because of the central role of IgE in allergic inflammation, neutralisation of effector functions and inhibition of IgE-synthesis are attractive means of therapy. READ MORE

  5. 5. Accelerated granular matter simulation

    Author : Da Wang; Martin Servin; Jin Ooi; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; discrete element method; nonsmooth contact dynamics; multibody dynamics; granular media; simulation; projected Gauss-Seidel; validation; iron ore pellets; pelletising balling circuit; model reduction; design optimization;

    Abstract : Modeling and simulation of granular matter has important applications in both natural science and industry. One widely used method is the discrete element method (DEM). It can be used for simulating granular matter in the gaseous, liquid as well as solid regime whereas alternative methods are in general applicable to only one. READ MORE
