  2. 1. Arsenic accumulation in plants for food and phytoremediation : Influence by external factors

    Author : Claes Bergqvist; Maria Greger; Sylvia Lindberg; Lena Ma; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arsenic; accumulation; availability; distribution; habitat; phy-toremediation; rhizosphere; redox potential; speciation; Plant Physiology; växtfysiologi;

    Abstract : Arsenic (As) appears in the environment as various As species, which may vary in plant uptake and toxicity. Moreover, As exposure may vary between habitat due to availability and speciation, both of which are influenced by redox potential. To decrease As uptake, addition of silicate may be a tool.

  4. 2. Wireless Communication Networks for Time-critical Industrial Applications

    Author : Xiaolin Jiang; Carlo Fischione; Nikolaj Marchenko; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datalogi;

    Abstract : Wireless communication is of paramount importance to enable the vision of Industry 4.0. Compared to mobile communications, industrial communications pose demanding requirements in terms of ultra low latency and high reliability. READ MORE

  5. 3. Efficient Backhauling in Cooperative MultiPoint Cellular Networks

    Author : Tilak Rajesh Lakshmana; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coordinated multipoint; scheduling; quantization errors; precoding; particle swarm optimization; stochastic optimization; decentralized architecture; prediction errors;

    Abstract : The efficient use of the spectrum in cellular systems has given rise to cell-edge user equipments (UEs) being prone to intercell interference. In this regard, coordinated multipoint (CoMP) transmission is a promising technique that aims to improve the UE data rates. READ MORE

  6. 4. Television Practices : Ethnography, Television and User Practices

    Author : Elin Önnevall; Oskar Juhlin; Alexandra Weilenmann; Johan Lundin; Stockholms universitet; []

    Abstract : This thesis explores television practices in a time when new technology has made it possible to interact with and create your own TV content. The work is focused on how user practices need to be understood in a context of chan- ging technology. READ MORE

  7. 5. Structural characterization of Deinococcus radiodurans phytochrome in solution

    Author : Lidija Vrhovac; Sebastian Westenhoff; Vladislav Orekhov; Magnus Wolf-Watz; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biokemi; Biochemistry;

    Abstract : Phytochromes are red/far-red photoreceptors which control a wide spectrum of biological processes inplants, fungi, and bacteria. Although phytochromes have been extensively studied, their mechanism ofaction still remains elusive. The signaling mechanism suggested by crystal structures involves refoldingof the so-called PHY tongue. READ MORE
