Popular Abstract in Swedish Tidigare trodde man att den vuxna hjärnan inte hade någon förmåga att nybilda nervceller. Detta skulle innebära att nervceller aldrig blev ersatta om de skadades eller dog. Nu vet man däremot att den vuxna hjärnan fortfarande producerar nya nervceller från särskilda moderceller, s.k. stamceller, belägna i åtminstone två områden i hjärnan: subgranulära zonen i hippocamThe adult brain constantly produces new neurons from endogenous neural progenitor cells located in at least two regions, the subgranular zone (SGZ) in dentate gyrus of the hippocampus, and the subventricular zone (SVZ). Major efforts are underway to discover the functional significance of new neurons in the adult brain. Several studies have indicated a relationship exists between newborn hippoca

Popular Abstract in Swedish Den s.k. "uncertain dichotomous choice" modellen används för att beskriva gruppbeslut. Modellen består av två komponenter: gruppstruktur och röstsystem. Gruppen utgörs av ett antal personer med ett gemensamt mål. Medlemmarnas uppgift är att välja ett av de två givna alternativen, av vilka det ena är korrekt. Dessa två symmetriska alternativ antas så utformade att det inA probabilistic framework used in studying collective decision making is the uncertain dichotomous choice model. The model is essentially characterized by two components: the organizational structure and the voting process. By organizational structure, we refer to a group composed of members with common objectives and who are tasked to choose one of the two given alternatives, one of which is assu

As international competition increased towards the end of last century, companies realized the importance of collaborating and sharing information with suppliers and customers to remain competitive. By sharing information such as forecasts of future demand with partners in the supply chain, it was possible to lower inventory holding costs and increase the service level to customers, and thereby in

Popular Abstract in Swedish Nästan alla träd i våra skogar lever i samspel (symbios) med svampar. Många av dessa är ”vanliga” svampar, sådana som vi är vana vid att se och plocka i naturen, (exempelvis soppar, kremlor, riskor, flugsvampar och kantareller) men det finns också de som inte bildar fruktkroppar, eller har fruktkroppar som vi inte ser. Fruktkropparna, de som kan hamna i svampkorgen, är Elevated nitrogen (N) deposition is an environmental problem that can affect plants and microorganisms, which are vital for the terrestrial N and carbon (C) cycles. This thesis has investigated the response of ectomycorrhizal fungi (EMF) to increased N deposition. Ectomycorrhizal fungi form mutualistic interactions with the roots of woody plants, including almost all boreal and temperate forests

Popular Abstract in Swedish Vår egen tid kännetecknas av ett mycket stort intresse för Förintelsen, det vill säga nazisternas folkmord på Europas judar. Denna bok försöker skissera några viktiga aspekter av den kulturella förståelsen av Förintelsen, genom att studera hur den avbildats i visuell kultur. Med "visuell kultur" förstås ett brett spektrum av kulturella uttryck, från dokumentär- och presThis thesis examines the representation in visual culture of the Holocaust, the Nazi genocide of European Jewry. It is divided into three main parts, each one focusing on a particular aspect of Holocaust representation. Part 1, "Meaning" (chapter 1-3), begins by considering the important role played by documentary photographs from the concentration camps for the public knowledge and conception of

The Viking Age (c. 800 – c. 1050 AD) was a period of dramatic change and transformative encounters across Europe and the wider world. Ships, seafarers, and the sea were central to these developments but, paradoxically, the Viking Age is generally studied through evidence and approaches on land. This has consistently hindered scholarly understanding of the maritime dimensions of the Viking Age; sur

Turbulent heat transfer over rough surfaces is crucial in natural and industrial processes, yet it has received less attention than that of momentum transfer. Recently, research in this field is rapidly growing, driven by advancements in computational methods, the role of surface roughness in meteorology, and the growing use of Additive Manufacturing technologies for energy and thermal management

Electrospun nanofiber membranes (ENMs) with unique porous 3D network structure exhibit properties such as high porosity and surface area, fine-tuned surface functionality and uniform pore sizes. This makes them candidates for water/wastewater applications with excellent flow. This study focuses on the fabrication of polymeric and composite ENMs from polyacrylonitrile (PAN) and nanoclay (NC) and th

IGF-1 is an essential regulator of fetal growth and brain development. Preterm birth in the human is followed by a rapid decrease in serum levels of IGF-1 and decreased levels of IGF-1 have been associated with development of severemorbidity. A recent clinical trial indicated that supplementation with IGF-1 prevented development of severe intraventricular hemorrhage (IVH) in extremely preterm infa

Popular Abstract in SwedishDenna doktorsavhandling har studerat förskolebarns kamratkompetens och speciellt uppmärksammat tre aspekter som är av central betydelse för barns samspel med kamrater; prosocialt beteende, aggressivt beteende och social kognition. Prosocialt beteende är handlingar som på något sätt gynnar en annan person (t ex hjälpa, trösta och dela med sig). Trots att prosocialt beteenThis doctoral thesis explored three broad aspects of preschoolers’ social competence: prosocial behavior, aggression, and social cognition. The longitudinal study followed forty-four children (initially 22-40 months), who were observed in natural peer interactions at their daycare centers during a two-month period in each of three con-secutive years. In addition, social-cognitive data were gathere

Typical for Western classical music is the process of interpreting and conveying a written score into sounding music. However, sometimes the communication of musical issues between musicians may be experienced as aggravating. In educational contexts in a broad sense, it might be advantageous if this communication could be facilitated, for example, by using visual illustrations as a complement to t

All over the world there is a shortage of adequate, affordable housing that enables social integration and sustainability. Many individuals and households have access to housing but live in different kinds of involuntary isolation with respect to age, gender, income, culture and ethnic background. There is a lack of housing forms that can contribute to solving these societal challenges through dif

In order to satisfy the growing energy needs of our planet’s population, and at the same time mitigate global warming, sustainable energy sources such as solar energy are indispensable. In addition to conventional silicon-based solar cells, nanotechnology offers interesting approaches for complementary applications. Multi-junction solar cells based on III–V semiconductors hold today’s world-record

So far, the semiconductor nanowire research area has mainly delivered results on growth procedures and related material properties. As the development lately has been successful in producing novel nanowire-based structures for optical or electronic applications, the time is ripe to review the device work that has been done and in some cases has produced devices ready for the market. In this chapte

Discourse theory methodology provides an alternative and novel framework for human rights implementation as a topic of legal research. By conceptualising implementation of international human rights norms in a national legal context as a play of discourses competing for hegemony, it becomes possible to explore the workings of human rights constructions as well as where and how implementation fails

Packaging serves a lot of purposes, and would be hard to do without. Packaging protects the goods during transport, saves costs, informs about the product, and extends its durability. A transport package is required to be strong and lightweight in order to be cost effective. Furthermore, it should be recycled because of environmental and economical concerns. Corrugated board has all of these featu

Context. The solar vicinity is currently populated by a mix of stars with various chemo-dynamic properties, including stars with a high metallicity compared to the Sun. Dynamical processes such as churning and blurring are expected to relocate such metal-rich stars from the inner Galaxy to the solar region. Aims. We report the identification of a set of old super-metal-rich (+0.15 ≤ [Fe/H] ≤ +0.50

Alloys and bimetallic systems have shown many advantages in heterogeneous catalysis, but the details of their catalytic functions are not always known. For instance, the atomic details about surface reconstructions under catalytic reaction conditions, or which phases that are high-active or low-active. Furthermore, the model catalysts studied in laboratories often differ a lot from the industrial
