Land ecosystems contribute to climate change mitigation by taking up approximately 30% of anthropogenically emitted carbon. However, estimates of the amount and distribution of carbon uptake across the world's ecosystems or biomes display great uncertainty. The latter hinders a full understanding of the mechanisms and drivers of land carbon uptake, and predictions of the future fate of the land ca
Popular Abstract in German Spannungsgesteuerte Kalziumkanäle haben eine große Bedeutung in vielen elektrisch erregbaren Zellen, wie z.B. in Nervenzellen und pankreatischen beta-Zellen. Hier werden sie folgendermaßen aktiviert: In der Nahrung enthaltener Traubenzucker (Glukose) wird nach einer Mahlzeit über den Blutstrom im Körper verteilt und in die beta-Zellen über Glukosetransporter aufgenommen.Voltage-gated Ca2+ channels are essential transducers of cellular signals in many electrically excitable cells. In the pancreatic beta-cell they mediate controlled Ca2+ influx, which is the final trigger for Ca2+ dependent release (exocytosis) of the blood glucose lowering hormone insulin. Several subtypes of voltage-gated Ca2+ channels are known and the L-type has been found to be the main contri
Various Helicobacter species have been isolated from the stomach, intestinal tract and liver of a variety of mammalian and some avian species, and Helicobacter DNA has been detected in human bile and liver samples. An immunoblot assay was established to analyse serum antibody responses to non-gastric Helicobacter species in patients with autoimmune liver diseases, in comparison with healthy indivi
Microorganisms in forest ecosystems normally recycle nitrogen (N), such that gaseous losses and leaching are limited. Mobilization of organic N, including microbial N, and immobilization of inorganic N, especially NH4+, are the quantitatively most important N transformation processes. Various factors influence their rates, e.g. the amount of carbon and nitrogen, temperature, moisture, and the micr
Widespread presence of toxic and persistent pollutants in the environment, even at low concentrations, causes risks of adverse effects to human health and the ecosystem. Biological methods for treatment of water streams and removal of persistent pollutants are of great interest due to their simplicity, low cost, and mild operational conditions without harmful by-products. The purpose of this resea
BACKGROUND The nature and underlying mechanisms of an inverse association between adult height and the risk of coronary artery disease (CAD) are unclear. METHODS We used a genetic approach to investigate the association between height and CAD, using 180 height-associated genetic variants. We tested the association between a change in genetically determined height of 1 SD (6.5 cm) with the risk of
We live in a time of wireless technologies, robotics and small computers with very high computing power. This is mainly due to a large emphasis given towards the study of semiconductor materials which are the building blocks of today's electronic industry. One of the secrets behind creating faster computers is the ability to integrate more and more transistors on a small semiconductor chip. GordonThis thesis studies the role of interaction between charged particles for transport and optical properties in nanostructures. Simulations are provided for a quantitative description of the system dynamics probed by either current spectroscopy or light absorption. In the first part of the thesis (Part I) the basic theories are described and in the second part of the thesis (Part II) the papers list
Produktion av en nanotrådssolcell För att ta itu med miljöpåverkan från växthusgaser krävs en övergång till förnyelsebara energikällor. Ett exempel på en sådan källa är nanotrådssolceller. I mitt examensarbete har jag undersökt hur nanotrådar kan arrangeras på sådant sätt som krävs för att kunna omvandla solljuset till elektricitet. Global uppvärmning är ett hot som till stor del orsakas av utslThe demand for cheaper and more efficient solar cells is high. One way to decrease cost of material, while maintaining a high degree of efficiency, is to take advantage of nanomaterials. A thin film containing pn-junction nanowires can convert light with an efficiency comparable to traditional planar cells, while using a fraction of the material, and thus reduce costs.

Bakgrund: Till följd av att den globala konkurrensen tilltar, ökar komplexiteten, flexibiliteten och produktvariationen inom produktion. Detta leder till att förbättringsprojekt blir allt svårare att genomföra. Händelsestyrd simulering har i litteraturen blivit identifierat som ett verktyg med förmågan att lösa dessa utmaningar, men till följd av att komplexiteten i en produktion ökar, växer ocksåBackground: Following a growing global competition, complexity, flexibility and product variability of manufacturing systems are increasing. This has led to improvement projects becoming more difficult to carry out. Discrete event simulation (DES) has in literature been identified as having the capability to solve these challenges, but as complexity of a manufacturing system increases so does also
Produktionen av kemikalier på Perstorp AB genererar kontaminerat avloppsvatten som renas i industriparkens egna avloppsreningsverk innan de kan återanvändas till processen igen. Industriparken i Perstorp har villkor från avloppsreningsverket på hur mycket vatten som fabrikerna får släppa ut till avloppsreningsverket. Det finns fortfarande kapacitet kvar innan villkoret uppnås, men marginalerna serThe production of chemicals at Perstorp AB generates contaminated wastewater that is treated in the industrial park’s own sewage treatment plant before it can be reused in the process again. The industrial park has conditions from the sewage treatment plant on how much water the factories may discharge. There is capacity left before the condition is reached, but the margins look to decrease in the
Flera olika synsätt på rättskraftens omfattning har genom historien presenterats. Traditionellt sett har ett samband mellan rättskraften i 17 kap. 11 § Rättegångsbalken (RB) och 13 kap. 3 § st. 3 RB, taleändringsregeln, utpekats. Genom Högsta domstolens avgöranden har rättskraften utvidgats och rättsläget börjat klarna. Denna uppsats syftar till att dels undersöka rättskraftens omfattning närmre, Several different opinions on the scope of res judicata have been presented throughout history. Traditionally a connection between res judicata in chapter 17, article 11 of the Swedish Code of Judicial Procedure (RB) and the rule of amendment in chapter 13, article 3, paragraph 3 RB has been pointed out. Through the rulings of the Supreme Court the scope of res judicata has been expanded and its d
En kall eftermiddag den 23 december 1947 hände något fantastiskt på ett laboratorium i New Jersey, USA. Forskare vid Bell laboratoriet demonstrerade för första gången en funktionell transistor! Transistorn är en elektrisk komponent som har tre terminaler där man kan ansluta andra komponenter. Om man leder en ström eller spänning genom ett par av terminalerna kan man kontrollera strömmen genom ett As the limits of transistor feature size scaling is reaching its saturation, new innovations are needed to prevent performance loss. High performance transistors on the III/V semiconductor platform implemented with ferroelectric oxides might in the future satisfy this demand. But the integration of ferroelectrics on materials such as InAs degrades the substrate and other vital components from the
Studien ämnade att undersöka hur väl personlighet respektive könsidentifiering, var för sig respektive tillsammans, kan predicera ideologisk orientering. För att undersöka detta användes personlighetstestet HEXACO och könsidentifieringstestet BSRI. Syftet med uppsatsen var att öka väljarförståelsen. Studien utgick ifrån ett bekvämlighetsurval (N=272), med 171 kvinnor och 101 män. Samtliga var svenThis aim of this thesis was to examine how well personality and gender-identification, by themselves and combined, were able to predict ideological orientation. This through the personality test HEXACO and gender-identification test BSRI. The purpose of the study was to help improve the understanding of Swedish voters. The sample was a convenience sample (N=272), with 171 women and 101 men, all Sw
Today the newly emerging Chinese MNEs have increasingly been involved in the internationalization activities, but they have not attracted adequate attention in terms of internationalization studies. This paper will be based on Dunning’s Eclectic (OLI) Paradigm as theoretical foundation and deploy the method of case study to analyze the internationalization strategy of the Chinese high-technology M
Det centrala för denna uppsats är att ur ett borgenärsinriktat perspektiv utreda två alternativ för rekonstruktion av företag; företagsrekonstruktion genom FrekL och rekonstruktion genom konkurs. FrekL är en tämligen ny lag i den svenska insolvensrätten. Tidigare rekonstruktioner av företag skedde så gott som alltid genom konkurs, även om AckL fanns som alternativ. FrekL var bland annat tänkt likThe main issue in this essay is from a creditors perspective. Analysis will cover two alternatives for the reorganization of companies: First, the Swedish correspondence, “FrekL,” to the American Chapter 11 and, second, reorganization through bankruptcy. FrekL is a fairly new law within the Swedish insolvency law. Earlier reorganization of companies were almost always made through bankruptcy, ev
Principen jura novit curia ålägger domstolen en skyldighet att utreda och tillämpa gällande rätt. Den anses traditionellt även medföra att domstolen inte är bunden av parternas åsikter i rättstillämpningsfrågan, eller har en skyldighet att uppmärksamma parterna ifall den överväger tillämpa rättsregler de inte hänfört sig till. Inkorporeringen av Europakonventionen (EKMR) i svensk rätt har medfört the principle jura novit curia imposes a duty onto the court to investigate and apply the relevant legal rules. Traditionally the principle is also considered to entail that the court is untethered by the parties opinions or instructions concerning the application of the law. Neither is the court compelled to inform the parties whenever it considers applying a legal rule the parties have not refer
In many process industries samples are taken and analyzed in laboratories to monitor and ensure proper production conditions. If the analysis result is not within specification limits measures are taken to correct errors. It has proved to be hard to take the appropriate measures. The problem description fits into the confines of control theory and the aim is to make a fairly simple solution to a v
Problemställning: Till följd av Bergendahls Foods tillväxt de senaste åren har företagets transportplanering blivit allt mer komplex. Planeringen sker i dagsläget manuellt vilket gör att slutresultatet kommer allt längre från det optimala. För att anpassa planering och transporter till den ökande efterfrågan krävs en grundlig genomsyn av transporterna. Studien ämnar därför göra en kartläggning ochProblem: The manual transportation planning at Bergendahls Food has recent years become increasingly complex due to the growth in demand. In order to adjust to the changes, Bergendahls Food requires a thorough mapping of their transportation activities. The lack of supporting IT-system obstructs the ongoing transport review why this case study aims to map and analyze the transports in order to inv
Sammanfattning Sedan den första november 2008 har metoden för framställning av muntlig bevisning i hovrätt ändrats. Med anledning av reformen ”En modernare rättegång” moderniserades rättegången i hovrätten. Moderniseringen innebar bland annat att ljud- och bildupptagning som gjorts i tingsrätten, i regel spelas upp som muntlig bevisning i hovrätten. Nu finns förslag på att den delen av hovrättsförSummary Since November 1st 2008, the method of presenting oral testimonies in the Swedish Court of Appeal has changed. Since the reform “More modern court proceedings” the trials in Court of Appeal have become modernized. The modernization meant, inter alia, that audiovisual recording that have been conducted at the Swedish District Courts are, as a rule, played at the Court of Appeal. The recordi
