Många olika aktörer är på skilda sätt involverade under en produkts livscykel. Samhällets miljöpolitik syftar till hushållning med råvaror som resurser och att undvika eller minska negativ. Den första fallstudien behandlar kött och har sitt huvudsakliga fokus på miljöpolitikens styrmedel kring produktion och distribution, med utblick mot konsumtions- och avfallsfaserna. Livsmedelsprodukter har e
Aerosolsammansättningen i ett renluftsområde i Mellansverige (Velen) har studerats under en årscykel. Aerosolpartiklarna har uppdelats efter aerodynamisk storlek i 7 fraktioner. Varje fraktion från 113 provtagningstillfällen har analyserats m a p svavel och tungmetaller m h a partikelinducerad röntgenstrålning s k PIXE-analys. Resultaten påvisar variationer i ämneskoncentrationer mellan enskilda m
Digital forensic investigators experience a need for support in their everyday struggle to overcome boundary problems associated with cyber crime inves-tigations. Traditional methods are socio-culturally and physically localised and dependent on strict and historically prescriptive political management. The new internet-worked cyber-world creates unprecedented difficulties for digital forensic inv
Popular Abstract in Swedish Östersjön är ett grundhav med tillförsel av saltvatten från havet och sötvatten från omgivande floder. De två vattenmassorna är vertikalt skiktade, vilket resulterar i en estuarin cirkulation, vilken har genomgått stora förändringar till följd av landhöjningen efter senaste nedisningen. För att kunna rekonstruera havsmiljöers förändringar bakåt i tiden är det nödvändigtThe Baltic Sea is a continental shelf sea that is influenced by both river runoff and marine water. The two water masses are vertically stratified in the Baltic Sea, resulting in a positive, estuarine circulation system, which has undergone changes in the past due to isostatic uplift of the Baltic basin. For researchers to understand past changes in the marine environment of the Baltic Sea, a soun
Abstract in UndeterminedThe purpose of this study is to preliminarily evaluate Chile’s energy and climate policy performance historically (1971-2007). The objective is to estimate different indicators in relation to energy and CO2 emission intensities, and identify policy instruments in the light of estimated trends and related structural issues. The methodology is based on a top-down decompositio
In the present work the feasibility of using various optical/laser based techniques for characterization of the afterburner of a full-size aircraft engine have been investigated. The tests have been performed on-site at Volvo Aero Corporation and were mainly directed towards surface thermometry using thermographic phosphors and fuel visualization. All applications were studied for different engine
The research group from Humanities laboratory at Lund University, Sweden, presents three strands of research on language and cognition where eye-tracking methodology has been used as a window on the mind. The paper includes: (1) eye tracking studies on picture viewing and picture description showing the dynamics of how speakers perceive, conceptualize and spontaneously describe complex visual scen
Short leukocyte telomere length (LTL) may be associated with several psychiatric disorders, including major depressive disorder (MDD). Short LTL has previously been associated with poor response to psychiatric medications in bipolar disorder and schizophrenia, but no studies have prospectively assessed the relationship of LTL to SSRI response in MDD. We assessed pre-treatment LTL, depression sever
The workshop brings together differing perspectives on what makes research data possible. How data is made represents an on-going negotiation between a number of elements. It reflects, firstly, the nature of disciplines and thecomplex way this is linked to cultures of research data and data sharing. Secondly, data is made across the complex temporalities within different practices of its managemen
Ljus består av elektromagnetiska vågor som pulserar genom universum med olika frekvenser. Vanligt ljus, som det som kommer från solen och från våra lampor, innehåller ett spektrum av många olika frekvenser. De olika vågornas toppar och dalar svänger inte heller i takt, utan är förskjutna i förhållande till varandra. I laserljus däremot, svänger alla vågor samtidigt upp och ner och med samma frekveThis thesis adresses modeling of quantum cascade lasers using non-equilibrium Green’s functions. Focus lies on the quantitative modeling of the gain when the systems are exposed to strong laser fields, as under realistic opertional conditions. In the first part, an introduction to the general concepts is provided, together with a discussion on approximate analytic expressions. The second part cons
The objective of this chapter is to contribute to the understanding of the growth of this global data-driven market ecology, mainly in order to pinpoint important regulatory challenges, where individual choice and agency, as well as competition, seem undermined. Truly, this development holds many promises for new innovation, some more disruptive than others, but also poses challenges that in this
Popular Abstract in Swedish Cellulära mekanismer vid ischemisk tolerans Stroke, hjärntrauma, hjärnblödning och övergående hjärtstillestånd, leder till minskat blodflöde till hjärnan (ischemi) och orsakar hjärnskador. Mot denna skadeutveckling finns ännu inte något medel för kliniskt bruk. I djurexperimentella ischemimodeller har man kunnat skydda hjärnan mot ischemiska skador genom att utsätta hjäA brief period of sublethal ischemia in the brain induces resistance to a subsequent, otherwise lethal ischemic insult. This phenomenon is known as ischemic tolerance or preconditioning. A model of ischemic preconditioning in the rat brain using the two-vessel occlusion model of global cerebral ischemia was established. Using this model we have demonstrated that ischemic preconditioning protects t
The particle size distribution in 11 different dwellings was studied during 5-7 days, samples being taken every 15 min. Large variation in the aerosol concentration has been found. Also the size distribution of the aerosol varies depending on the level of activity in the home, e.g. smoking and cooking. The average area median diameter found in the dwellings was 0.2 ,am. A technique for the measure
Syftet med studien är att synliggöra ett konfliktfält med berättelser om det moderna Sverige som uttrycks av olika politiska grupper och att främja bearbetningen av tolkningskonflikten. Fyra politiska utmaningar mot den etablerade framgångsberättelsen om Sveriges utveckling från ett fattigt land till en modern välfärdsstat analyseras: 60-talsvänstern, den nya kvinnorörelsen på 1970-talet, alternatThe aim of the study is to make visible a field of conflicting narratives of modern Sweden expressed by different political groups and to contribute to the working through of the conflict of interpretation. Four political challenges to the established success story of Sweden's development from a poor society to modern welfare state, are analysed: the Left in the 1960s, the new Women's movement in
NERICA is a new group of high-yielding and stress-tolerant upland rice varieties, developed by the Africa Rice Center to address the continent-wide rice challenge, poverty and food insecurity. Recognizing that African women farmers do not always benefit from the introduction of productivity-enhancing technology and higher-value crops, the aim of my thesis is to understand processes leading to NERI
