Popular Abstract in Swedish Funktionen hos hemoglobin från ryggradslösa organismer är mer varierande än motsvarande för ryggradsdjur, vilket möjligen speglar de mer mångfasetterade behoven inom den förra gruppen. Hemoglobin har strukturella likheter med andra hemproteiner/enzymer och uppvisar även överlappande enzymaktiviteter, med funktioner utöver transport och lagring av syre. Under syrefattigThe function of non-vertebrate haemoglobins (Hbs) appears more diverse than that of vertebrate Hbs, possibly reflecting the various demands to be met among their hosts. Sharing structural features with other haem proteins/enzymes, Hbs display a qualitative overlap in activities with functions extending beyond oxygen transport/storage. When subjected to oxygen deficient conditions, the obligate ae

Technology transfer is important to understand how knowledge is transformed to economic value. Applying a case study approach, this thesis investigates the technology transfer efforts from the University of Dar Es Salaam to indigenous informal SMEs in Tanzania and examines the impact of one of their technology transfer mechanisms on the specific technological capabilities that were acquired at the

To run a Diesel engine in Homogeneous Charge Compression Ignition (HCCI) mode has proved to be a highly promising approach towards reduced engine-out emissions of NOx and particulate matter. A crucial issue when utilizing HCCI is the degree of charge homogeneity that is required to achieve the desired low temperature combustion. A very well mixed charge can be created through the use of traditiona

Packaging affects the logistical and environmental efficiency of supply chains. The purpose is to increase knowledge of the current state, trade-offs and improvement potential of packaging logistics in supply chain practice. The research is based on 22 cases, each of which consists of supply chain mapping and structured interviews with three supply chain actors (manufacturer, distributor and retai

Popular Abstract in Swedish Cholecystokinin (CCK) och gastrin är två välkända mag-tarmkanals hormoner. CCK namngavs efter sin förmåga att stimulera gallblåsans kontraktion och gastrin visade sig vara involverad i utsöndringen av magsyra. Allt eftersom antalet publikationer gällande dessa hormoner har vuxit har också en mångfald andra funktioner tillskrivits respektive hormon, bland annat har bäggeCholecystokinin (CCK) and the related hormone gastrin have been claimed to exert trophic effects in the pancreas and gastrointestinal tract. Two types of receptors for CCK and gastrin are known to exist, the CCK-A and the CCK-B receptor. They differ in their affinty for CCK and gastrin. The CCK-A receptor has about 500 times higher affinity for sulfated than for non-sulfated CCK and gastrin, while

Landscape is fundamental to human experience. Yet until recently, the study of landscape has been fragmented among the disciplines. This volume focuses on how landscape is represented in language and thought, and what this reveals about the relationships of people to place and to land. Scientists of various disciplines such as anthropologists, geographers, information scientists, linguists, and ph

Popular Abstract in Swedish Skillnader i bearbetning av emotionella stimuli Den centrala frågeställningen i den här avhandlingen rör huruvida den emotionella laddningen av ett stimulus ger upphov till skillnader i den kognitiva bearbetningen. Är det så att negativt laddade stimuli (t.ex. ord som ”massaker”, ”våldtäkt”, bilder på hotfulla ansikten, eller bilder av otrevliga eller hotande situationeThe central phenomenon investigated concerns the valence-based process asymmetry found in several earlier studies (e.g. Pratto & John, 1991; Taylor, 1991), where negative stimuli seem to initiate more thorough processing than positive stimuli. This finding was consistent in the three empirical studies forming this dissertation. In Study 1 (three experiments) emotionally valenced words were pre
