  2. 1. Prior informed consent and hazardous trade : Regulating trade in hazardous goods at the intersection of sovereignty, free trade and environmental protection

    Author : David Langlet; Said Mahmoudi; Günther Handl; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; informed consent; PIC; trade bans; effective sovereignty; environmental law; free-trade law; hazardous substances; wastes; chemicals; GMOs; Environmental law; Miljörätt; miljörätt; Environmental Law;

    Abstract : This dissertation analyses international and to some extent domestic law pertaining to trade in hazardous substances. Hazardous trade regulation is found to promote or accommodate three objectives in particular: the strengthening of the ability of (importing) States to exercise control of transboundary flows of hazardous substances; the protection of human health and environment; and the avoidance of impediments to the free flow of goods.

  4. 2. Numerical modeling of auroral processes

    Author : Jörgen Vedin; Kjell Rönnmark; Robert Lysak; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; space plasma physics; auroral acceleration region; auroral current circuit; Alfvén waves; parallel electric fields; equation of state; fluid simulation; PIC simulation; Space physics; Rymdfysik;

    Abstract : One of the most conspicuous problems in space physics for the last decades has been to theoretically describe how the large parallel electric fields on auroral field lines can be generated. There is strong observational evidence of such electric fields, and stationary theory supports the need for electric fields accelerating electrons to the ionosphere where they generate auroras.

    Abstract : Photonic integrated circuits (PICs) combine hundreds of optical components on a chip, and can enable fast communications, high-performance computing, and improved sensing. PICs, made by miniaturized optical waveguides, require many reconfigurable elements to enable programmable functionalities and to compensate for fabrication variations and environmental factors.
