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
In fire safety engineering, information about the expected walking speed of occupants through smoke is one factor that is of great interest to the designer. However, despite the fact that research already in the 1970s demonstrated that people tend to evacuate through smoke, little research has been performed on the topic, and evidently there is a lack of data on walking speed in smoke. This has cr
Popular Abstract in English The eye is a complex device in charge of producing clear and sharp images of the outside world. While some people need glasses early on in their lives, others have nearly perfect vision until, all of a sudden, they have to hold books or documents further and further away from their eyes to be able to read them and eventually have to resort to reading glasses. This visuaHealthy eye lenses are transparent and flexible, able to adapt shape in order to focus on far away and close-by objects. With age, however, this flexibility is lost, leading to a condition known as presbyopia. This vision disorder where close-by objects appear blurred commonly starts around the age of 40. The aim of this thesis is to elucidate the molecular origin of the gradual hardening of the c
The hypoxic zone in the Baltic Sea has increased in area about four times since 1960 and widespread oxygen deficiency has severely reduced macro benthic communities below the halocline in the Baltic Proper and the Gulf of Finland, which in turn has affected food chain dynamics, fish habitats and fisheries in the entire Baltic Sea. The cause of increased hypoxia is believed to be enhanced eutrophic
The growing world electricity demand and environmental concerns pushes toward new technology for electricity production. Within the thermal processes for electricity production, two axis of research are being developed to meet the needs of the industry, namely using renewable fuels and new generation burners technology. The first direction is to develop new processes able to use renewable fuels. B
1. Mossy fibre evoked activity in the cerebellar cortex elicited by peripheral electrical stimulation was studied in chloralose anesthetized cats. The distribution of intracortical field potentials in the C3 and D zones was mapped in order to determine if there is a spread of synaptic activity outside the mossy fibre termination area. This area was identified by the presence of short latency synap
Purpose – The aim is to understand customers' willingness, or unwillingness, to pay a price premium in the market for consumer packaged food and what kind of images brands can use in order to achieve a price premium. Design/methodology/approach – The study is based on a quantitative survey of brand images found in food and branding literature and their impact on loyalty as well as customers' will
Popular Abstract in Swedish Från skärva till kärl fokuserar på ett arkeologiskt massmaterial, en materialkategori som är särskilt vanlig framför andra bland de arkeologiska fynden. Skärvor är fragment av keramiska kärl och analysen kommer att färdas från det lilla till det något större - från skärva till kärl. I centrum återfinns de kärl som varit i bruk i Uppsala från 1100-talets mitt till 1700-tAbstract From Sherd to Pot. A Contribution to the History of Everyday Life in Uppsala tackles the question: how is the culturally created reality produced, fixed, and changed, and how can this be related to the social structure as a whole? The hypothesis is that changes in society result in new cultural patterns which can be read in objects. The work consists of three main parts, an extensive summ
Background Families with parental intellectual disabilities (ID) are likely to need support in achieving a decent family life. In order to accurately plan for such support services, society needs data regarding the occurrence of those parents and their children. The aim of this study was to investigate the 5-year incidence of children born to women with ID in a county in Sweden. Methods Women born
Hemicelluloses extracted from wheat bran have to be separated from impurities in order to obtain a valuable product at high concentration and purity. A previous investigation showed that separation by ultrafiltration is possible, but the flux was low due to the high viscosity of the solution and the presence of gel-forming substances in the solution. In this investigation the influence of prefiltr
Changes of the electronic structure accompanied by charge localization and a transition to an antiferromagnetic ground state were observed in the organic semiconductor (DOEO)(4)[HgBr4]center dot TCE. Localization starts in the temperature region of about 150 K and the antiferromagnetic state occurs below 60 K. The magnetic moment of the crystal contains contributions of inclusions (droplets), and
Accessibility is an important factor in land-use planning and several methods have been developed to calculate and to predict it. Nevertheless, it is seldom applied in planning situations, maybe because many land-use planners and elected officials lack the knowledge and resources needed to use traffic models. Consequently, accessibility is often used as a concept and a goal in daily planning, but
The notion of human rights is built on the fact that they are universal rights and thus applies to everyone without exceptions. Despite this irregular workers are denied their labour rights and their human rights due to the fact that they are living in a country unlawfully. The states use methods as regularizing irregular migrants or enabling tougher sanctions against irregular migration in order
Before going into details and regulations behind the safeguard measures it's important to understand the basic starting point. The members of WTO all agree to have tariffs at a certain level and the member countries are prohibited to raise the tariffs above this level. This makes the system predictable&semic every one knows the tariff levels. Speaking in a broad sense one can say that this
The purpose of this Master Thesis was to design an automatic separator, a machine that would separate organic from non-organic waste through a mechanical process. The use of a mechanical process was one of the target specifications given by WTM AB, the company that initiated the project. WTM is a small machine design company located in Ängelholm, Sweden, who designs machines for different kind of
As part of research into small group homes run by local authorities for those with severe mental illness the characteristics of the social environment was investigated. The ideal and real versions of the Community Oriented Program Environmental Scale (COPES) were administered to residents and staff of small group homes in a county in southern Sweden. Both these groups were also interviewed on thei
Laser-induced fluorescence (LIF) investigations have been performed in connection with photodynamic therapy (PDT) of basal cell carcinomas and adjacent normal skin following topical application of 5-aminolaevulinic acid (ALA) in order to study the kinetics of the protoporphyrin TX (PpIX) build-up. Five superficial and 10 nodular lesions in 15 patients are included in the study. Fluorescence measur
New technology is always coming and with that comes changes. The technology has made it easier to fulfil each customer's demand. The customer has today much more different products to choose between and the stores have problems to get the right product to the right place at the right time. It is hard for the supply chain to forecast what the customer is going to buy the next day, especially if
