Hur effektiv och säker är rekombinant och renad plasma faktor VIII-behandling för hemofili A patienter?

Haemophilia is an inherited disease which causes increased bleeding due to defect clotting factors VIII and/or IX. There are two forms of haemophilia, A and B, which both are X-linked and due to mutations of the genes of factor VIII and factor IX respectively. This study focuses on Haemophilia A and thereby factor VIII.The drugs that are available on the Swedish market today for patients with haemophilia A include Factor VIII(FVIII), which has been purified from human plasma and recombinant factor VIII(rFVIII). The main goal of this study is to gain a better understanding of the effects of treatment of haemophilia A with either purified plasma factor VIII or recombinant factor VIII on reducing or preventing bleeding and on side effects.  The study was designed as a literature review and searches were carried out in PubMed at the Linnaeus University library.  The criteria for selection of articles were: patients with haemophilia, treatment with plasma derived and/or recombinant factor VIII as well as clinical studies.

Upplösning i staden : En studie av individ och struktur i Paul Austers City of Glass

The main purpose of this paper is to analyse the relation between the spatial and individual structures in Paul Austers City of Glass. The interpretative discussion is focused on the novels metafictive aspects. The analyses consists that Quinn, the main character, is linked to the city environment because of his function as detective, flânuer and author. According to Baudelaire, Benjamin and Berman the two last positions are fundamental in the literary citystructure, as well as in the formation of individuality and modernity..

Källsorterade systems påverkan på avloppsreningsverk : växthusgaser, energi- och resursanvändning i modellstudie

The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.

Framtidens stadsträd för en fungerande grönstruktur

The effect of climate change places demands on how we build cities. Cities have to be built denser to meet the objectives of sustainability but as a result of this densification city green areas are at risk of exploitationand disappearing. The question this raises is whether there has to be an opposition between a dense and a green city?Urban trees are playing a very important role in cities. They stand as the major part of the vegetation in citieswhich are otherwise dominated with concrete and stone.

OTEC för Tarawa

Ocean Thermal Energy Conversion, OTEC, a technology using the temperature difference between cold deep seawater and warm surface water, can extract the work in the form of electricity. OTEC gives also synergies of drinkable fresh water. The temperature difference has an impact on the efficiency of the technology, which means that the feasibility of OTEC is geographically limited. The project intends to explore the possibility of replacing the atoll Tarawa?s present electricity generation with an OTEC plant and to explore synergies. In the present situation all of Tarawa?s electricity is generated by fossil fuels.

Hållbara uppvärmningsalternativ för Grinda Wärdshus : En studie om uppvärmning med pellets och flis

This report is a bachelor's thesis of two students from the Energy and Environment degree at KTH Stockholm. Grinda is an island situated Stockholm archipelago. Skärgårdsstiftelsen is landowners and manages the area. Grinda Wärdshus, a guest house located in the island, currently uses an oil-fired boiler as a heating system. The aim of this thesis is to investigate whether wood chips or pellets is, from a sustainability standpoint, a suitable heating method for the guest house.

Striden om det svenska snuset : En studie av identitetskonstruktioner i den svenska rapporteringen om EU:s tobaksdirektiv

This paper examines constructions of identities in Swedish news paper articles concerning the European Unions?s Tobacco Products Directive. Using critical discourse analysis (CDA) supported by theories of discourse, semiotics and identity formation, this paper argues that constructions of a Swedish ?Us? are distinguished from a non-Swedish ?Them?. These constructions depends on categories such as use of tobacco, science, history and war, which are frequently used in the discourse to separate ?Us?, ?the good? from ?Them?, ?the bad?.

Handel med utsläppsrätter - hur företagsstrategier påverkas :

Climate change is one of the most difficult problems that humans have to deal with. Today, the evidence of human effects on the climate change and the rise of temperature on earth are strong. It is extremely important that all countries get together and cooperate in order to be able to solve the problem with climate change. One step in the work on climate changes is the Convention on Climate Change, which was agreed on in 1992. The Convention on Climate Change resulted in the Kyoto Protocol in 1997. The Kyoto Protocol is an agreement between a number of industrialized countries to limit or reduce the green gas emissions.

Verkan på befintliga servitut vid fastighetsbildning : En studie av lagstiftningen och den praktiska tillämpningen

Syftet med denna uppsatts är att utreda hur befintliga servitut påverkas vid fastighetsbildning? vad som gäller enligt svenskt regelverk och hur det tillämpas praktiskt. Fastighetsbildning innebär förändring av fastigheter, genom antingen nybildning eller ombildning. Ett servitut är en begränsad rättighet som är belägen på en fastighet, som belastas av rättigheten, och som får nyttjas av en annan fastighet, som har förmån av rättigheten. I samband med fastighetsbildning kan befintliga servitut komma att påverkas på olika sätt.De metoder som använts är: (1) en litteraturgranskning där den svenska lagstiftningen studeras; (2) en fallstudie där utförda förrättningar studerats om huruvida befintliga servitut påverkats vid fastighetsbildning och (3) en intervjustudie med yrkesverksamma förrättningslantmätare som arbetar på Lantmäteriet.Undersökt litteratur visar att Jordabalken och Fastighetsbildningslagen reglerar hur befintliga servitut påverkas vid fastighetsbildning.
