Biobränslen anses vara ett miljövänligt alternativ till fossila bränslen eftersom de har potential att minska de globala utsläppen av växthusgaser. Studier har visat att en ökad användning av etanol kan komma att påverka atmosfärens kemiska sammansättning och på så sätt bidra till förhöjda koncentrationer av marknära ozon, en luftförorening som är känd för att orsaka ökad dödlighet. Furaner kan frBiofuels are considered to be an environmental friendly alternative to fossil fuels as they have the potential to reduce the global emissions of greenhouse gases. Studies have showed that an increased use of ethanol could alter the atmospheric chemical composition and enhance urban ozone concentrations resulting in higher human mortality rates. In recent years furanic compounds have been considere

Second-order scalar-relativistic Douglas-Kroll-Hess density functional calculations of the electric field gradient, including an analytic correction of the picture change error, were performed for 34 tin compounds of which molecular structures and Sn-119 Mossbauer spectroscopy parameters are experimentally known. The components of the diagonalized electric field gradient tensor, V-xx,V-yy, V-zz, w

The role of islet constitutive nitric oxide synthase (cNOS) in insulin-releasing mechanisms is controversial. By measuring enzyme activities and protein expression of NOS isoforms [i.e., cNOS and inducible NOS (iNOS)] in islets of Langerhans cells in relation to insulin secretion, we show that glucose dose-dependently stimulates islet activities of both cNOS and iNOS, that cNOS-derived nitric oxid

The ECL cells in the oxyntic mucosa secrete histamine in response to gastrin, stimulating parietal cells to produce acid. Do they also operate under nervous control? The present study examines histamine mobilization from rat stomach ECL cells in situ in response to acute vagal excitation and to food or gastrin following vagal or sympathetic denervation. Applying the technique of microdialysis, we

Popular Abstract in Swedish Äldre personer som erhåller permanent hjälp i sitt dagliga liv har ökat i takt med att livslängden ökat. Många äldre personer kommer troligen framöver att erhålla hjälp i sitt ordinära boende, eftersom den kommunala vården och omsorgen framför allt inom särskilt boende har minskat i omfattning i förhållande till antalet äldre över 65 år. Svensk policy strävar mot att alThe aim of this thesis was to investigate self-reported diseases and complaints, quality of life (QoL), help received with activities of daily living among older people and in relation to who provided the help, and in comparison with those without ADL help. The aim was also to investigate older people’s experiences of receiving help. Data were collected using postal questionnaires in two populatio

Streptococcus pyogenes is an important human pathogen that causes significant morbidity and mortality worldwide. In order to successfully infect the human host, S. pyogenes is equipped with tools that modulate the human immune defence. The present thesis explores how different streptococcal proteins interfere with innate immunity, adaptive immunity, and blood coagulation. M protein is a surface-b

Popular Abstract in Swedish Vill man ta en bild av något som rör sig mycket snabbt, krävs det att man använder en kort exponeringstid. Om kamerans slutare är öppen under för lång tid, hinner det man vill fotografera röra sig under tiden filmen exponeras, med resultatet att bilden blir suddig. Kemiska reaktioner där atomer och molekyler är inblandade är exempel på något som sker på väldigt kort tidWhen a low-frequency laser pulse is focused to a high intensity in a gas, the electric field of the laser may become comparable to, or even exceed, the electric field between the electrons and the nucleus in the atom. Under such conditions, through a process known as high-order harmonic generation, bursts of extreme ultraviolet radiation may be emitted, with durations in the attosecond domain (1 a

Addressing key environmental concerns during humanitarian assistance is critical to prevent additional hazards, reduce risks, and to not further increase the vulnerability of disaster-affected populations. However, the environment remains an underappreciated cross-cutting issue within the humanitarian sector and efforts to systematically integrate environmental concerns into humanitarian assistanc

Denna uppsats syftar till att undersöka hur svensk rätt reglerar envarsgripande. Envarsgripande innebär, enkelt uttryckt, rätten för varje individ att, under vissa förutsättningar, gripa en annan person. Detta är något som samhället, enligt den svenska lagstiftaren, principiellt sett bör uppmuntra. Samtidigt bör kommas ihåg att brottsbekämpning främst är statens uppgift och straffprocessuella tvåThe purpose of this paper is to examine how Swedish law regulates citizen’s arrest. Put simply, Citizen’s arrest means the right for every individual to, under certain conditions, apprehend another person. According to the Swedish legislator this is something that society in principle should encourage. However, one should keep in mind that law enforcement is primarily a task for the state. Furthe

Denna framställning utgör en rättslig analys av Gällivare tingrätts dom angående Girjas sameby. Denna dom är i skrivande stund inte slutligt avgjord utan har överklagats till hovrätten. Tingsrätten slöt sig till att rennäringslagen stred mot egendomsskyddet i regeringsformen och lämnade denna lag utan avseende. Domstolen dömde till samebyns fördel i målet med stöd av rättsinstitutet urminnes hävd.This essay accounts for a legal analysis of a case that has been ruled by a Swedish district court (Girjasdomen). This case is appealed to a court of appeal, so the matter has not yet become final. The court stated that parts of the reindeer industry law (rennäringslagen) were not applicable in the current case due to the conflict with the property protection (egendomskyddet). The court ruled in f

Den organiserade brottsligheten ökar i Sverige och skördar fler dödsfall varje år. Brotten är svåra att utreda då de ofta sker gränsöverskridande och med tekniska hjälpmedel. Vissa anser att den brottsbeivrande verksamheten inte har tillräckliga verktyg för att stoppa de grovt kriminella där tystnadskultur råder. Utan vittnesmål kan vissa brott inte klaras upp och dagens lagstiftning innehåller inOrganized crime is increasing in Sweden and harvests more deaths every year. The crimes are difficult to investigate as they are often of international character and executed with technical aids. Some believe that the police does not have enough tools to stop these criminals in which silence culture prevails. Without testimonies, some crimes cannot be resolved and with the legeslation of today the

It is well known how important belonging and to be part of something is for us humans and our well-being. Other utterly important foundations for us and our sense of freedom are safety and accessibility. LGBT-research has profoundly been conducted on larger cities, but lacking substratum on how mentioned factors affect people living in smaller cities. In this paper, I try through interviews unders

Issue of Study: The master thesis was conducted at Tetra Pak, a large multinational manufacturing firm within the business to business setting. They have a history of renowned innovations and have with their innovations, become the market leader within their industry. In recent history, they have tried using open innovation for certain projects in an ad hoc manner, but do not have any clear vision

The connection of devices to the internet is referred to as Internet of Things (IoT). By using IoT distributed network of devices will be able to communicate with each other. The management and forming of distributed applications is, however, very complex since IoT uses devices that have different capabilities and that do not have the same communication protocols. Calvin is an open source applicat

Om dina ögon vore lika känsliga som astronomers toppmoderna teleskop skulle du kunna se långa band av ljus när du kollar upp mot himlen. Dessa band kallas stjärnströmmar och befinner sig i yttre delen av våran galax, Vintergatan. Strömmarna skapas från en klump av stjärnor, t.ex. en dvärggalax, medan de roterar runt Vintergatan. Det som händer är att stjärnor slits loss från klumpen och dras ut tiThe orbital approximation for stellar streams is the assumption that all stars in a stream can be described as following the same orbit. In this thesis, I evaluate this approximation as a method for constraining the potential of the Milky Way. I wrote a program in MATLAB which integrates the orbits of test particles in a potential model which resembles that of the Milky Way's halo and disc. Th

The relationship between a Non-Governmental Organization (NGO) and a government can be unpredictable, which could complicate the NGO’s operations in a resource dependent environment. If a government decides to abruptly cut its official development assistance allocation towards the civil society; does that not only reflect the government’s new development policy but it might also jeopardize the con

Around the world, the treatment of food waste is a major administrative and environmental problem throughout the food supply chain. Beijing, as any other mega city, is facing vast issues of sustainable food waste treatment in addition to efforts for food waste reduction. Presently the majority of Beijing's food waste is treated together with the mixed residual waste in landfills (53%) and inci

Mediation processes are becoming increasingly salient in western society, and since tourism is one of the characteristics of modern societies the tourism practices follow this increase. The increasing emphasis on the visual as a prominent sense for our understanding of the physical world has led to increase desire for photography. Social media has created platforms for new remedies of photo sharin

STYRD KYLNING AV GJUTGODS – ett allt hetare ämne Många industrier står idag inför stora utmaningar angående resurseffektivitet och energi-användning, inte minst de som involverar väldigt energikrävande processer. Metall- och gjuteriindustrin står idag för ungefär 15% av energi-användningen i Sverige.
