Morgondagens effektiva fjärrvärme : En beskrivande litteraturstudie

This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.

Tidsperspektiv som prediktor för individuella skillnader i upplevd stress : En tvärsnittsstudie av äldre vuxna

Time Perspective is related to mental and physical health. This study examines the relationship between Time Perspective and perceived stress where Time Perspective was expected to predict the level of perceived stress. Past-negative, Future-negative, Future-positive and present-fatalistic were expected to be positively associated with perceived stress while Past-positive and present-hedonistic were expected to be negatively associated. Measures from the self-assessment forms S-ZTPI, PSQ-recent and CES-D from 445 participants (242 women, 203 men) between 60-90 years were used to examine the hypothesis of the study. Two hierarchical multiple regression analysis confirmed that Time Perspective is associated with perceived stress and in part 2 explains it's variance, one when adjusting for demographic data (.R = .37) and the 2 other when adjusting for demographic data and depressive symptoms (.R = .13).

Praktisk Fysik : Laborationernas och demonstrationernas vara eller inte vara.

Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..

How Venture Capitalists can use their Network in order to reduce the Information Asymmetries between themselves and the Venture Management Team

The purpose of this study is to increase the understanding of how venture capitalists can use their network in order to reduce information asymmetries between themselves and the venture management team. A qualitative approach with semi-structured interviews, consisting of open questions, have been used to receive gradate information in order to reach our explorative purpose. Our theoretical framework consists of relevant studies made on the dynamics of networks and the problems that can arise in the complex relationship between a principal and an agent. We have been interviewing two venture capital firms and therepresentatives from two business angel networks. We also made an additional interview with an influential financial actor in order to try to verify our conclusions Our conclusions are that an extensive network can be used by venture capitalists in order to; verify ventures? technologies, complement the competences in the venture management team, and arrange co-investments, resulting in reduced information asymmetries between themselves and the venture management team.

Den svenska CleanTech-marknaden : aktörer och finansiering

This thesis describes and examines a new line of business, CleanTech. CleanTech comprises a wide range of different types of companies and is not yet well defined. In this thesis only the Swedish market is considered, and a variety of players on the market are included to give the most extensive picture of the current situation. Recent research shows that a gap has arisen between governmental financing and private equity-investments in CleanTech-companies. This gap occurs mainly in companies in expansive phases and causes problems both for the companies and for the line of business as a whole. To investigate this gap the Swedish CleanTech-business is described in terms of earlier and existing financing, age and size of the companies and their turnover and profit.

"ESS avgörs i Bryssel": Nätverk söker förankring i institutionell beslutsstruktur

This paper aims at describing and explaining the bi-and multilateral negotiations that are, and have been, taking place between Sweden's chief negotiator Allan Larsson and European countries, and within the EU institutions in Brussels, in order to seek support for the Swedish offer to host the European Spallation Source, ESS. It applies a case study method using political science theories ? governance and government ? and to a large extent information from the involved actors in the policy process. The paper also presents a constructive position, in showing how the negotiations on ESS can turn into a process leading to a decision on the construction of this research facility. ESS is negotiated in networks on bi- and multilateral levels consisting of European research representatives and financiers.

Värdet av demand response på den svenska elmarknaden

Intelligent IT-based solutions, often called Smart Grids, are considered to be the future balancers of renewable energy sources. One area within the Smart Grid concept is called demand response, which is focused on making customers more consumption flexible by making them more active in their consumption. In this thesis the aim is to analyze a business model by investigating the income potential for a demand response solution as well as its market potential. This has been done through literature studies, interviews and development of a computational model.The use of 5000 households with flexible consumption can provide a cost reduction of 17.2% or 2.4 million SEK for a balance responsible party during an average year. If the solution is used to make strategic bids on the regulation markets the study indicates that the largest potential for revenues lies within this strategy.

In this study embryos from llamas were transferred to alpaca recipients. In a parallel study alpaca embryos were transferred to llama recipients. All animals used were free of uterine and ovarian abnormalities detectable by rectal palpation and /or ultrasound examination. Embryos were harvested twice after single ovulation in 10 mated female llamas and non-surgically transferred to synchronized alpaca recipients.

Systemutveckling i praktiken : konsten att tillmötesgå den okända användarens krav

ABSTRACT System development has become more and more concentrated on development for the Web and this has resulted in larger target groups. It will most surely continue to be so considering that the Web will be the infrastructure of business and services in the future. A big target group involves that the owner of a system can earn a lot of money from the paying users, but that assumes that the system can meet user needs. If a system on the Web does not satisfy the user?s demands then they will use the competitor?s system instead because it is only a mouse-click away.

Low Temperature Waste Heat Solutions : with proposals for energy technological actions based on Scania?s building 64

The report comprises two separate parts:part 1:  Temperature needs for district heating in the paint shop for axles in building 210part 2:  Energy and low temperature waste heat solutions in heating and cooling systems for   building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.
