This paper explores the issue of private retail governance to deliver SCP. In particular it focuses on the role of private retail eco-brands to promote sustainability both upstream and downstream in the food supply chain. The analysis and discussion centers around the question whether private retail eco-brands are better fitted to introduce sustainability into the food supply-chain than 3rd party

Popular Abstract in Swedish Stora mängder reaktiva lågmolekylära ämnen används i den kemiska industrin vid produktionen av varor som hanteras i vårt dagliga liv. Exempel på sådana kemikalier är organiska syraanhydrider (OAA). En stor andel av de arbetare som exponeras för dessa viktiga industriella föreningar blir tyvärr sjuka med symtom som astma och hösnuveliknande besvär. I åtminstone en del faOrganic acid anhydrides (OAAs) are important industrial chemicals but also potent inducers of airways diseases. Many exposed workers develop specific IgE and IgG antibodies. Hexahydrophthalic anhydride (HHPA) and methylhexahydrophthalic anhydride (MHHPA) are two particularly sensitising OAAs. The aim of this thesis was to develop and evaluate a method for biological monitoring of exposure to and r
The purpose of this contribution is twofold. First, we revisit the longitudinal component (also referred to as common-mode component, asymmetric component or antenna-mode component) occurring at the receive side of a twisted-pair loop. Second, we propose a simple setup for RFI tests that captures reality more accurately than performing differential-mode and common-mode tests separately. In essence
This thesis describes optical spectroscopy on III-V semiconductor nanowires. The nanowires were grown by metal-organic vapor phase epitaxy (MOVPE) and chemical beam epitaxy (CBE). Photoluminescence and photocurrent spectroscopy are used as tools to investigate issues such as the size of the band gap, the effects of surface states, and the charge carrier transport in core-shell nanowires. The ban
While the liturgical centre of the church is the high altar in the chancel, the western part of the Romanesque church has often been ascribed a more secular character. This seems to be an area where those in power could assert their authority in a religious setting. The magnitude of these manifestations vary greatly, from the ostentatious westworks of the cathedrals and the miscellaneous forms of
A Geomaterial structures always involves local inhomogeneities in the material, which give rise to shear bands in the soil structures. This phenomenon decreases the strength of the material considerable and it is the objective of this paper to study the material behaviour micromechanically or locally and then investigate global responses. The imperfections are introduced in form of stiff gravel pa
