En jämförelse av energiåtgång och emissioner för olika persontransportslösningar i Stockholm stad

This master thesis sets out to compare the different public transport modes in Stockholm city.Both energy consumption and air pollution are compared. The chosen transport methods are car,bus and metro.Traditionally the rail industry has had environmental arguments as a strong competitiveadvantage when it comes to passenger transportation. However, in recent years the automotiveindustry has been getting more positive media attention regarding environmental issues, forexample Roger Kemp?s statement that the car is the most environmental friendly passengertransportation mode in the UK. This study will show the environmental advantages of railwaytraffic in cities.The energy sources of the world are not endless and the use of the different sources affects theenvironment in different ways.

Ha?llbara alternativ inom sjo?farten : En utva?rdering av metanol och va?gkraft som marina drivmedel

Vision Nollenergihus : Energiförsörjning av passivhus med sol- och vindenergi

Climate change is the modern society?s common issue. The developed countries areconsuming more than what is sustainable, and the climate change due to the use offossil fuels can be seen clearly. EU has specified goals, in order to stop furtherdamage, which demand that every member state have to reduce its energyconsumption by 20 % before 2020 and 50 % before 2050, relative to 1995.The Swedish government uses a number of instruments to encourage reduction in theusage of energy, but every individual has to contribute to reach the goals.With increasing energy price the cost of living is going up. A lot of people are lookingfor ways to save energy and not be affected as much by the increasing price.Investments for insulation, replacement of windows and replacing old heating systemfor a new efficient heat pump is getting more and more common.This thesis is about investigating the possibilities in becoming independent from buyingenergy for households.

Illegal rovdjursjakt : en rättsekonomisk analys av rovdjursproblematiken i Sverige

In this essay a model of a potential illegal hunter?s decision-making is created and presented in order to provide an overview of important parts of the complexities associated with the current Swedish predator policy. A comparison is made between a livestock owner?s economic incentives, and the expected costs faced by the potentially caught lawbreaker. In accordance with economic theory the benefits and costs of illegal hunting are compared and thus the optimal choice is determined where marginal costs and benefits are equal.

Planerarens kompetenser

It is a well known archaeological concern that the remains of human bones left from the bronze age and early iron age Scandinavia are not nearly enough to represent the estimated population of the time. Furthermore the bones of each find rarely represent a whole individual. The majority of the bones must have been disposed of somewhere else, possibly scattered in running waters or in the fields, where they have evaporated or are securely hidden from archaeological excavations.This thesis deals with the grave concept and the problem in using a word that is so very clouded by its modern, western meaning. It also offers an alternative explanation to why the bones are handled the way they are and why they are found in such awkward contexts..

Prestation vid sönderdelning av GROT med olika typer av maskiner

There is a need for productivities data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses.Four types of machines with three different working principles were compared at six studies during winter conditions. Three to eleven trials during 9.5 to 30.7 minutes were made on each machine. Samples from the produced material at each study were sieved to determine the size distribution of the comminuted material. Samples were also taken from the studies for determination of moisture content.

Skötsel av älgskadade bestånd :

Sweden has today the highest moose (Alces alces) population in the world. The population has been very high since the late seventies and in the beginning of the eighties there was a big ?moose explosion?. The main food source for moose during the winter is young pine (Pinus sylvestris) and birch (Betula spp.). The high moose population has therefore lead to high damage on pine forests over big areas.

Fascia Panel Redesign

The purpose of this project has been to cut production costs for the fascia panels ofGetinge?s largest autoclaves. The cost for the stainless steel plates currently used is veryhigh. An alternative material solution could cut costs significantly.In addition, improvements have been made to the instrument tower which is a central partof the fascia panel. As a result of the new modular design in a new material theinstrument tower has been improved in several aspects..

Förbereda sig för att fira gudstjänst -men hur? : En undersökning av från 1986 års kyrkohandbok avvikande beredelsemoment

In this essay I examine how in seven different congregations that belong to the Church of Sweden the preparatory office is formulated in ways that differ from the form that is prescribed in the current service-book of the Church of Sweden. My purpose is to examine how and why the congregations have chosen these alternative preparatory offices. This I have tried to find out by reading the written instructions and/or homepages of the congregations, studying their orders of service and interviewing one pastor in each congregation.Before describing, comparing and commenting on the different ways these congregations have chosen to formulate their preparatory offices, I give a historical background to the preparatory office itself and how it is formulated/designed in the current service book of the Church of Sweden. I also describe the history and the introduction of the Kyrie.I then describe each congregation, trying to point out the main characteristics of it, then concentrating on the process that lies behind the urge to formulate an alternative preparatory office, the reasons for it and the results.One of the conclusions I draw is that in the congregations I have examined there is an ongoing discussion about and reflection on the advantages of including the Kyrie in the preparatory office. I also found that in the congregations there are different opinions about the words following the prayer of penitence - should they be words of direct absolution or words that speak about the promise of God's forgiveness? This discussion is closely connected to a discussion about what is the connection between the preparatory office and the holy communion/Eucharist.

En omöjlig Gud? : en jämförelse mellan gudsbilden i postmodern teologi och östkyrklig apofatisk teologi

In some postmodern philosophy and theology, the view of God has returned to the centre of the discussion. God is seen as a living reality beyond human conception. Some of the contemporary philosophers even relate to the negative or apofatic theology. They often do this as a contrast to the positive theology. The view of God in postmodern theology and philosophy is beyond our rational knowledge.
