Värmeväxlare med luftkonditionering för tvättstugor

The energy in laundry rooms, in form heated air, can be utilized with a heat exchanger. A concept and an early prototype of the heat exchanger have already been developed to show that the theory works. This report describes the continued development and construction of the product.A field study was made in order to investigate the environmental usage and establish the product design. The most common washing machine was used as a calculation model, and calculations were also made to estimate the amount of energy in the air. A previous analysis of the existing prototype is also presented in this report, to show the products potential capacity.

Nitrat i grundvattnet : Modellanalys av vattenflöde till Hörviks vattentäkt

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

Motivation till livsstilsförändring : En kvantitativ studie om motivation till livsstilsförändring via gruppverksamhet

Länsförsäkringar in Värmland, Sweden, had during the year 2003 a total level of 6.1 percent of people on the sick-list, which was higher than average in the business (4,5%) and for salaried employees in the private sector (3,3%). The average age of those put on sick-list was 47 years, whish is four years higher than the average for the whole LF-group. The cost for the total amount of people being on sick-list at LF-company (6,1%) was estimated to 1 500 kkr, according to a calculation model coming from Försäkringskassan. For every percent the sick level could be reduced, the company would save 239 kkr. To map out the state of health of each and every collaborator in LF, the company offered all employees to make a health profile at the company's health service, Clarahälsan AB.

My patience ran out on Hasad a long time ago? - varför blev Syrien en ondskans axelmakt?

In 2002 George W. Bush held a speech where he classified six nations as being the main threats to American security, one of them being Syria, a state with a secular constitution, no resent offence towards the US, and with an improved diplomatic relationship to the US during the Clinton years.Being an ally to the Soviet Union during the Cold War Syria was forced to redefine its role in the region. Using neorealistc theory one part conlusion is the fact that the new Syrian leader, Bashar al-Hasad, in the early 21th century determined to set higher goals for the Syrian power ambition in the Middle East, threatened to destabilize the region and leave the US and its allies in a caotic situation.In the US, however, the new administration after 11/9 sharpened its tone towards states that did not cooperate in the new ?war on terrorism? or/and were likely to harbour terrorists. Syria was accused of doing both.

Verktyg för lönsamhetsberäkningar vid bränslekonvertering av spetslastpannor från olja till pellets

This report summarizes the development of a calculation program estimating the profitability of converting a peak-load oil-fired boiler to pellets. To convert an oil-fired boiler to pellets a new fuel handling system must be designed. Changes also have to be made to some other components. Since there are many different techniques for transportation, storage and treatment of the fuel only the most interesting techniques from Swecos experience and interest were included in the study.The capacity of the different parts in the system was dimensioned based on the power of the boiler after conversion. To estimate prices, installed power and dimensions manufacturers and distributers were contacted.

Testmetodik för vintertestning av el- och hybridfordon

With gas prices persistently rising, electric and hybrid vehicles are getting more and more common and in recent years several new electric cars have evolved on the market. Although the energy consumption and low emissions are a huge benefit of the electric cars, they inevitably suffer from high prices, short range and time consuming recharging periods. To be able to withstand the competition it is important that electric vehicles not only can withstand general were and tare, but also the harsh conditions that ordinary cars is exposed to in daily usage. The purpose of this project is to develop a test methodology which replicate situations that could appear in daily usage of electric or hybrid cars and to understand the problems related to usage of electric cars in winter conditions. This paper also discusses the major differences between hybrid cars and electric cars.

Grön olja? - En fallstudie av ett oljebolags miljöprofilering

While the call for regulations against greenhouse gas emissions are louder then ever before, demand for oil is also at an all time high. Oil companies face the dilemma of making sound business without being perceived as environmental villains. In this essay I will examine how BP, one of the largest companies in the world, broke rank with the industry and devoted itself to being an environmental friendly oil company. The actions and motives of this change will be evaluated through up-to-date theories about company motivation to environmental adaptation. We see that BP:s transformation can be well explained through Simone Pulvers theory about the socially embedded company.

Storbankerna på den svenska bankmarknaden : Argument för och emot infrastruktursamarbetet enligt 19 § KL

The retail banking market in Sweden is highly concentrated and oligopolistic. This has been confirmed by numerous reports from different competition authorities within the EU, for example the Swedish competition authority. A considerably high number of different sorts of competition barriers has been pointed out in these reports. The competition barriers are mainly directed to the smaller banks and the potential competition. The retail banking market in Sweden is dominated by four major banks, which together has over 80 percent of all market shares.

Jordtäckta hus : Energiberäkningar och kostnadskalkyler på ett jordtäckt hus i Malmö

With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.

Ett svenskt landskap i Australien : svenska kyrkan i Melbourne

As a Swedish landscape architecture student living in Australia for five years, I have often wondered if my memories and my associations with the landscape and the nature in Sweden, are the same as other Swedish people living in Melbourne. Most of the Swedish people who live here in Melbourne remember and associate Sweden?s nature and landscape with where they grew up or where they used to live. The plants that most of the Swedish people I asked missed from Sweden were associated to special feelings or activities. The general type of landscape people remember from Sweden is that of a landscape covered in forests, which you can walk freely through. With these memories as a foundation and with inspiration from the Swedish landscape architect Thorbjörn Anderson?s way of creating places, by letting a few strong changes play against the existing elements,2 but also with consideration of the climate and the severe shortage of water that is current in Melbourne, will I create a design concept for the garden surrounding the Swedish Church in Melbourne. A design concept that will generate memories and associations to Swedish landscapes..

För ett socialt kapital av god kvalité : - Det förebyggande arbetet mot mobbning ur skolkuratorers och lärares perspektiv

The purpose of this study was to understand school counselors´ and teachers´ perspectives on the prevention of bullying in relation to social capital. The study was based on a qualitative process with semi-structured interviews from three teachers and three school counselors from three different schools. The main question was to find out teachers and school counselors perspectives of bullying in relation to social capital. The analysis was based on a theory that focuses on social capital, where trust and confidence as well as universal and selective interventions are important. Today, bullying is considered a serious and significant problem in school.

Designated Operational Entities. En legitim form av offentlig-privat governance inom ramarna för Clean Development Mechanism?

This thesis investigates the Designated Operational Entities (DOEs) under the Clean Development Mechanism (CDM) of the Kyoto Protocol. The DOEs serves as independent third-party auditors with the task of validating, verifying and certifying projects under the CDM. The majority of the DOEs are private entities. This is in line with the CDM objective of including the private sector in the climate change combat. The introduction of private entities in the role of DOEs can be questioned from a legitimacy point of view, but is corresponding to a development in international environmental governance where private actors are increasingly involved in governance arrangements.The thesis concludes the DOEs to be a form of public-private partnership and investigates the legitimacy of this form.

Primärenergianvändning av passivhus i Sverige : Med fokus på Kvarteret Trettondagen

The building sector accounted for around a fourth of the total energy usage in Sweden in year 2010 (Energimyndigheten, 2012). Therefore it has become very interesting to achieve a lower energy usage in residential buildings. One way to achieve that is to build so called passive houses. By being very well insulated and have low leakage through the walls, they can reduce the energy usage for heating with a substantial amount. The first passive house was built during the 90?s in Germany; and in Sweden the first passive house was built in Gothenburg 2001.

Design och förädling av en liten och kustnära trädgård :

2. SUMMARY A small garden exposed to a harsh coastal climate can be difficult to design. Limitations in space and in plant varieties increase the needs of an in-depth knowledge to achieve wanted goals. In this degree project the challenge has been to create a functional and position adapted garden for a very small beach house lot in Mölle, a little harbour village at the south coast of Kullaberg. ?Villa Malm?, is situated directly on the bedrock in a close settlement where the gardens, in most cases are very small and exposed to strong salty winds.

Byggkostnader inom mjölkproduktionen - jämförelse av olika stallstorlekar och byggnadstekniska utföranden

Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building. Herd sizes were 120, 250 and 400 cows. The milking equipments were automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with automatic cable driven scrapers on solid alleys, automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table. Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.
