Background. In SBRT of lung tumours no established relationship between dose-volume parameters and the incidence of lung toxicity is found. The aim of this study is to compare the LQ model and the universal survival curve (USC) to calculate biologically equivalent doses in SBRT to see if this will improve knowledge on this relationship. Material and methods. Toxicity data on radiation pneumonitis

The thesis is focused on an attempt to delay photoreceptor cell death in the rd1 mouse using Lens Epithelium Derived Growth Factor (LEDGF), Glutathione S-Transferase mu (GST-?? and Glutathione S-Transferase alpha (GST-?? in an organ culture paradigm as well as the role of metalloproteases (MMPs) and their tissue inhibitors in photoreceptor degeneration (TIMPs). The rd1 mouse model displays a reti

Following the East Asian success story Indonesia also subscribed to a model with increased productivity, income and equity through modernisation of agriculture. When it was hit by a severe crisis in 1997, Indonesia was regarded as one of the up and coming tigers of Southeast Asia. The crisis indicated that something was seriously wrong in the structure of the economy necessitating a re-examination

The main advantage of a heated-grid reactor for studying pyrolysis kinetics of solid fuel samples is that high heating rates of up to 1000 K/s can be obtained. However, one of the concerns is whether the temperature distribution over the grid material is uniform and whether the presence of a thermocouple welded to the grid causes any measurement errors. Biomass samples were placed on the heated-gr

This paper studies the inclusion of the indigenous population in the Guatemalan democratisation process. The indigenous population have throughout the history of Guatemala always suffered from exclusion. Thus it is interesting to study if there have been any improvements in their situation since the signing of the peace agreement in 1996. The base of our paper is Donna Le Van Cott’s article, Build

Europeanization as a crucial insrument for democrtatization process in target countries requires gradual complaince with EU membership conditions where conditional positive incentives (ultimately EU membership) in return are offered as rewards to acceding countries. Provoked by conflicts at domestic level, the current setbacks in Europeanization proceses of several countries (here is Turkey and Se

The purpose with this master thesis was to identify which problems that were related to the implementation of AFS 2001:1, examine what they were caused by and to some extent come up with solutions to the problems. In order to do this a feasibility study, a literature study and five interviews with people working with AFS 2001:1 were done. The people who got interviewed work in one large and one li

The aim of the thesis is to bring clarity to what extent the routines for risk management in different divisions comply with the ones used at OKG AB as a whole. A mapping of the risk management was made through interviews with members of staff. It was observed that a common risk identification method at OKG would serve many purposes. Literature on COSO’s framework for Enterprise Risk Management an

Popular Abstract in Swedish Drygt en tiondel av Sveriges befolkning lider av hjärt-kärlsjukdom som också är den vanligaste dödsorsaken. Många av de akuta sjukdomstillstånden orsakas av att en bit inflammerad blodkärlsvävnad bryts loss från sitt fäste i något av de stora blodkärlen, färdas med blodet och täpper till blodflödet i mindre blodkärl. Detta leder till syrebrist och celldöd nedströms om dAbstract Atherosclerosis is a multifactorial disease, but an unbalanced immune system plays a critical role in the disease development. A common theory states that a continuous stress to the vascular vessel wall initiates a repair process that however is insufficient to completely heal the tissue. This imbalance is associated with accumulation of cholesterol, which is an essential component of ce

Multi-target aptamer selection, known as multiplex systematic evolution of ligands by exponential enrichment (SELEX), is rapidly drawing interest because of its potential to enable high-speed, high-throughput aptamer selection. The parallelization of chemical processes by integrating microfluidic unit operations is a key strategy for developing a multiplex SELEX process. One of the potential probl

Popular Abstract in Swedish Den globala energianvändningen är idag större än någonsin. Faktum är att den, i takt med världens ständiga utveckling, kommer att fortsätta öka många år framöver. Sättet som energi har producerats på historiskt används dessutom i allra högsta grad fortfarande idag och innebär daglig förbränning av stora mängder organiskt material. Detta resulterar i en ökad koncentratioThis dissertation covers studies of excited state processes in two types of solar energy materials: alternating polyfluorene polymers and their blends with fullerenes in the active layer of plastic solar cells, and bis-tridentate RuII-polypyridyl complexes to be used as sensitizer in systems for artificial photosynthesis. The polymer:fullerene blends were studied by transient absorption and time-

Manager och Civil Servant är en utforskning av aktörers förgivet tagna antaganden vilka styr uppfattningar kring hur offentlig förvaltning ska ske i samtida välfärdsstater. Det hävdas att mer än 30 år av pågående och riktade reformer gentemot den offentliga förvaltningen har orsakat dilemman att uppstå. Dessa dilemman har resulterat i en förskjutning av balansen kring några fundamentala pelare inoManager and Civil Servant is an exploration of actors’ taken-for-granted assumptions that govern perceptions concerning how public administration should be undertaken within contemporary welfare states. It is argued that more than 30 years of continuous reforms directed towards public administration have caused dilemmas to arise. These dilemmas have resulted in a shifting of balances regarding the

The present thesis involves a process evaluation of what occurred in the treat¬ment of seven young patients in institutional care diagnosed with schizophrenia: what happened in the encounters between staff and patients in a ward environ¬ment designed to provide constant care, and what facilitated or hindered rehabili¬tation efforts. The aim of the process presentation was to portray the treatment

Dispossession and displacement have made their imprint on the lives of uncounted millions, and continue to pose the gravest threat to security for many more. The ascent of neoliberalism to global hegemony in recent decades – in all its multifarious and contextually path-dependent varieties – has radically changed the landscape of human vulnerability and security. Its successes in massive global an

This chapter explores the expansion of the Tupian peoples across greater Amazonia to better understand the mechanisms and processes of cultural and linguistic contact and change. Tupian languages are or were spoken among indigenous groups distributed from the Brazilian Atlantic coast through Paraguay to the eastern Andean slopes of Peru. The investigation uses GIS (Geographical Information Systems

A critical review is presented on the state of knowledge and calculation capability for coastal overwash. Overwash and overwash deposits (washover) accompanying hurricanes and severe storms can devastate coastal communities and habitat, but in many areas these processes are essential for maintaining the integrity of barrier islands while creating new habitat. This review covers general studies of
