Popular Abstract in Swedish Ökningen av växthusgaser i atmosfären har orsakat en global temperaturhöjning. Afrika anses vara en av de kontinenter som kan komma att bli mest utsatta av effekterna kring ökande temperaturer med mer frekventa torkor som följd. Satellitdata ger oss möjligheten att uppskatta biomassa över stora områden vilket i sin tur kan leda till att öka vår förståelse kring hur utbyWith the challenges Africa faces with respect to the predicted warming due to climate change, the continents role in the global carbon cycle has been increasingly recognized. Earth observing satellites have played a significant role in the study of vegetation, particularly in Africa where climate stations are sparse. Satellite data can provide the means to map plant primary production for monitori

The paper explores the ways in which experimental flintknapping has contributed to our knowledge of the past.

Popular Abstract in Swedish Fysiologiska och kliniska aspekter på förändrad kapillärpermeabilitet Graden av genomsläpplighet (permeabilitet) i de minsta blodkärlen (kapillärerna), där utbytet av näringsämnen och slaggprodukter sker, är avgörande för att kroppens celler skall fungera. I den svåraste fasen av sjukdomar såsom blodförgiftning (sepsis) och efter trauma är permeabiliteten ökad varvid plMicrovascular permeability is important for exchange of fluids and proteins in health and in disease. Permeability increases in critical illness, such as during sepsis/SIRS and after trauma, and may be affected by drugs. Increased permeability causes oedema and hypovolaemia. Hypovolaemia is treated with fluids, and their efficacy is determined by their intravascular retention, also influenced by t

To promote attainment and inclusion, Sweden offers tuition in migrant pupils’ mother tongues as a regular school subject. However, the formulation of learning aims is problematic, and resources allocated to the subject do not correspond to ambitions expressed in steering documents. This case study presents an analysis of the organization of Mother Tongue Studies at a highly diverse urban primary s

Regime shifts in lake ecosystems can occur in response to both abrupt and continuous climate change, and the imprints they leave in paleolimnological records allow us to investigate and better understand patterns and processes governing ecological changes on geological time scales. This synthesis investigates paleolimnological records that display apparent regime shifts and characterizes the shift

The paper reports experimental results on the intonation of wh- and yes/no-questions in Tokyo Japanese, and discusses several implications for the semantic and phonological theories of focus. The intonation of declarative sentences, wh-questions, and yes/no-questions are systematically compared. The results show that the wh-question exhibits an F0-prominence on the wh-phrase, while the yes/no-ques

Abstract: Bladder cancer is a heterogenous disease, ranging from minimally invasive, low-grade tumours with lowrecurrence rates and mortality on one end of the spectrum, and muscle invasive, high-grade disease prone torecurrence, progression and death at the other end.The aim of this thesis was to investigate the expression, clinicopathological correlates and prognostic significanceof the candidat

A DCIP survey, i.e. a geoelectrical survey with combinedmeasurement of DC resistivity and induced polarization(IP), was conducted in southern Sweden. The purposewas to identify soil depth and bedrock structures andvariations in rock quality.Data were acquired data with 100% waveform fromwhich IP of good quality data were extracted. Theinverted model sections show a wide variation in theelectrical

Uneven exposure to e.g. solar radiation can cause temperature differences between various structural parts of a bridge, which leads to tensile stresses if the parts cannot move freely. In this study, thermal simulations and stress calculations on a model of a portal frame bridge are performed with the aim of evaluating the temperature difference between the bridge parts. It is shown that the tempe

Popular Abstract in Swedish Diabetes, i dagligt tal även kallat sockersjuka, kännetecknas av konstant förhöjt blodsocker. Sjukdomen ökar lavinartat, och har beskrivits som en av det moderna samhällets stora epidemier. Diabetes förekommer i två huvudsakliga former, typ 1 och typ 2. I typ 1-diabetes, som framför allt drabbar barn och ungdomar, har de insulinproducerande beta-cellerna förstörts av krDefective insulin secretion from the pancreatic B-cells is a central feature in type 2 diabetes (T2D). There is a strong hereditary component in type T2D, but the underlying pathophysiology remains largely unknown. This thesis uses a combination of gene network analysis and cell-physiological techniques to explore the genetic and cellular basis for impaired insulin secretion in T2D. We found that

Context: The first therapeutic cancer vaccine demonstrating effectiveness in a phase 3 study was approved by the US Food and Drug Administration on 29 April 2010. The pivotal trial demonstrated overall survival (OS) benefit in patients treated with antigen-loaded leukapheresis cells compared with a control infusion. Results of other prostate cancer (PCa) vaccination strategies are awaited, as this

Popular Abstract in Swedish β-celler producerar insulin som frisätts när blodsockret höjs, t.ex. efter en måltid. Patienter med diabetes saknar de insulinproducerande β-cellerna eller har nedsatt känslighet för insulin. För de patienter som saknar insulin kan det vara svårt att reglera blodsockernivåerna i blodet trots dagliga injektioner med insulin, varför transplanterbara insulinproducerande β-Organogenesis of epithelial organs requires interaction between epithelial and mesenchymal tissues. During pancreas development, mesenchyme-derived structures induce specification, growth and differentiation of pancreatic epithelial cells. For instance, notochord, endothelial cells, and pancreatic mesenchyme are essential for the development of the pancreas. N-cadherin deficient-embryos suffer fro

Popular Abstract in Swedish Nivån på arbetsproduktivitet är särskilt betydelsefull i utvecklingsländer där det mesta av byggnadsarbetet utförs manuellt. Tidigare forskning har konstaterat att produktiviteten i byggindustrin är låg och i några fall sjunkande. Bristande produktivitet hos byggnadsarbetarna är en orsak till kostnadsöverskridande och förseningar av byggprojekt. Syfte med detta forskninProductivity of labour is particularly important especially in developing countries where most of the building work is still carried out on manual basis. Previous research has pointed out that productivity in the building industry is low and in some cases declining. Poor productivity of craftsmen is one of the causes of cost and time overruns on building projects. The objective of this research wa

Popular Abstract in Swedish Livmoderhalscancer är den näst vanligaste cancern för kvinnor i världen, över 500 000 kvinnor insjuknar varje år. Varje år dör dessutom 275 000 kvinnor av denna sjukdom. De flesta av de som insjuknar och dör bor i utvecklingsländer. I Sverige drabbas ca 400 kvinnor varje år. På sextiotalet i Sverige började vi screena för denna cancertyp i Sverige. Detta genom hälsokonCervical cancer is the fourth most common reason for cancer death amongst women worldwide, with 500 000 new cases every year. Most of these women live in developing countries. Cervical screening programs can reduce the incidence by 50%, but are not common in the developing world. In Sweden there are approximately 400 new cases of cervical cancer yearly, despite the existence of a screening program

Background and purpose Spasticity and muscle contracture are two common manifestations of cerebral palsy (CP). A spastic muscle may inhibit growth in length of the muscle, but the importance of this relationship is not known. In 1994, a register and a healthcare program for children with CP in southern Sweden were initiated. The child's muscle tone according to the Ashworth scale and the ankle ran

Popular Abstract in Swedish Titelns första del är ett Walter Benjamin-citat som bildar utgångspunkt och förklaras i avhandlingens första kapitel. Tidigare forskning, samlat till fyra tematiska områden, presenteras: drottning Kristina själv och hennes lärdom, bibliotekarierna och de andra lärda, det kungliga biblioteket i Stockholm och samlingen i Rom. Bibliotekets tidiga historia, hur det kommer tThis study examines how the Latin manuscript collection of Queen Christina of Sweden was formed, what function it served for the queen and for others, and how various attempts to impose order on it reflect different epistemological traditions. A recurring theme of the study is the creation of order and the title, The Mild Boredom of Order, a quotation taken from an essay on book collecting by Walt

Gällande entreprenadarbeten torde det vara vanligt förekommande att beställaren påtalar fel som denne vill att entreprenören ska avhjälpa. För att en part ska kunna aktualisera en påföljd vid påstått kontraktsbrott krävs enligt branschavtalet AB 04, precis som enligt allmän förmögenhetsrätt i övrigt, att en reklamation företas. Syftet med uppsatsen är därför att undersöka hur beställarens påkallanWhen it comes to contract work in the construction sector it is common that the client points out faults that he wants the contractor to rectify. For a party to be able to enforce a sanction in the event of an alleged breach of contract, the branch regulation AB 04 prescribes, just as according to general property law, that a complaint is made. The purpose of the thesis is therefore to investigate
