This study has observed and investigated random telegraph noise in the photoluminescence from InAs quantum dots in GaAs and InP quantum dots in GaInP. The dots are grown by the Stranski-Krastanow technique with a sufficiently low surface density that individual dots easily could be investigated. The luminescence from many single quantum dots, exhibiting switching between two levels, has been spect

The book contains the first part of an investigation aimed at finding out why it is morally wrong (at least prima facie) to cause species to go extinct. That it is morally wrong seems to be a very basic and widely held intuition. It seems reasonable that a moral theory worth taking seriously ought to be able to account for that intuition. The most common attempt to answer our question is to refer

Verification and validation activities take a substantial share of project budgets and need improvements. This is an accepted truth, but the current practices are seldom assessed and analyzed. In this paper we present a qualitative survey of the verification and validation processes at 11 Swedish companies. The purpose was to exchange experience between the companies and to lay out a foundation fo

IKEA is a product developing company, known for putting packaging and logistics issues at the top of its agenda. At IKEA, the product and the packaging are developed concurrently with the aim of lowering the total cost from the supplier to the customer. During the years 2002 to 2004, a pckaging redesign project was conducted at IKEA. The purpose of the project was to redesign the packaging for an

Spatially-coupled regular LDPC code ensembles have outstanding performance with belief propagation decoding and can perform arbitrarily close to the Shannon limit without requiring irregular graph structures. In this paper, we are concerned with the performance and complexity of spatially-coupled ensembles with a rate-compatibility constraint. Spatially-coupled regular ensembles that support rate-

The purpose of this essay is to give an image of the importance of humanitarian demining, it's difficulties and to what extent GPS can be a tool for this. A human rights perspective is used towards this through the entire work for what IMAS gives the parameters. GPS is a tool among others in the humanitarian demining process. GPS can be a tool in humanitarian demining especially in mapping min

Lagen (2002:599) om grupprättegång (GrL) trädde i kraft i januari 2003. Grupptalanförfarandet är intressant ur ett rättsvetenskapligt perspektiv eftersom taleformen skiljer sig mycket åt från den traditionella civilrättsliga tvåpartsprocessen i svensk rätt. Dess tillkomst är en reaktion på ändrade samhällsförhållanden och ett nytt affärsklimat som har bidragit till nya rättsliga problem. Det uppstIn January 2003, the Swedish Act (2002:599) on Group Litigations (GrL) came into force. It stipulated a possibility to initiate a Class Action in Swedish Courts. The Class Action as a litigation form is very different from the traditional civil proceedings in Swedish law. It is a reaction to changing social conditions and a new business climate that has contributed to new legal issues. During the

Aerial spraying is common procedure at banana plantations in Costa Rica even though the plantations often are situated very close to villages. The fungicide Mancozeb, which is metabolized into the more toxic substance ETU, is one of the pesticides used in aerial sprayings. This thesis has evaluated the exposure of ETU to children living in one of these villages and compared that exposure to differ

The purpose of this study was to examine how mangers in eldercare in the municipality of Helsingborg view the causes of burnout among employees and staff members, how they handle the situation when burnout appear and which preventive measures they use at the working site. The purpose was also to examine if the facts mentioned by the managers was supported by former studies and already existing res

The multi-layer dynamic model SAFE was applied to the forested catchment istebna (Southern Poland), to study recovery from acidification. Environmental pollution in the area has been historically high. The model uses data from an intensive monitoring plot established in 1999 in a spruce stand, which was planted in 1880. Observations showed that the soil was depleted of base cations. The measured b

Patients with blunt abdominal trauma and fatal outcome during 30 years in a well-defined rural Swedish area have been analyzed. There were 127 patients. Several facts indicate that more severe trauma has been appearing more often during this period The mortality rate has, however, been stable, but the patients have become older. More patients die from pulmonary complications than from the trauma i

MOS devices based on III-V semiconductors and thin high-k dielectric layers offer possibilities for improved transport properties. Here, we have studied the interface structure and chemical composition of realistic MOS gate stacks, consisting of a W or Pd metal film and a 6- or 12-nm-thick HfO2 layer deposited on InAs, with Hard X-ray Photoemission Spectroscopy. In and As signals from InAs buried

Social norms play a fundamental role in holding groups together. The rationale behind most of them is to coordinate individual actions into a beneficial societal outcome. However, there are cases where pro-social behavior within a community seems, to the contrary, to cause inefficiencies and suboptimal collective outcomes. An explanation for this is that individuals in a society are of different t

Subject movements and other disturbances might contaminate the Magnetic Resonance Spectroscopy data, and these artifacts can be misinterpreted as actual metabolite signals by the quantification program. Thus, an automatic method could be very helpful for finding artifacts and eliminating them. In this work, an approach of using correlation analyses was tested in order to evaluate if motion contami

Retinal pericytes play an important role in many diseases of the eye. Immunohistochemical staining techniques of retinal vessels and microvascular pericytes are central to ophthalmological research. It is vital to choose an appropriate method of visualizing the microvascular pericytes. We describe retinal microvascular pericyte immunohistochemical staining in cryo-sections, whole-mounts, and hypot

We study the process of charged polymer translocation, driven by an external electric potential, through a narrow pore in a membrane. We assume that the number of polymer segments, m, having passed the entrance pore mouth, is a slow variable governing the translocation process. Outside the pore the probability that there is an end segment at the entrance pore mouth, is taken as the relevant parame

Although extensively studied (and of large importance for food processing) there is still no general consensus on the time-dependent convective heat transfer coefficient (h) in immersion frying – reported values differ by orders of magnitude (4–7000 W m−2 K−1). Moreover, none of the many methods suggested have become a generally agreed upon standard. This study uses the general uncertainty managem

The article looks into the multicultural settings of Liviu Rebreanu’s novel “Amândoi” (Both) by briefly examining the representation of its main, minor or incidental characters, either intelligentsia or common people. Ethnicity, social and professional statuses are considered as elements of multiculturalism. The continuous increase of suspense, the open ending, the parody in the undertone, and the

This paper reports on Monte Carlo simulation results for future measurements of the moduli of time-like proton electromagnetic form factors, | GE| and | GM| , using the p¯ p→ μ+μ- reaction at P ¯ ANDA (FAIR). The electromagnetic form factors are fundamental quantities parameterizing the electric and magnetic structure of hadrons. This work estimates the statistical and total accuracy with which th
