Effektiviseringspotential inom industrisektorn : Energibesparing vid frekvensstyrning av centrifugalpumpar ? en fallstudie

The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..

Värdet av att bygga grönt för kommunala bostadsbolag

AbstractThe real estate sector is today responsible for 40 per cent of the total amount of energy consumption within the members of the EU. All over the world there are collaborations within research and projects to find ways of reducing the amount of energy consumed by the real estate sector. In Sweden, a directive from the European Union has posed demands on authorities as well as on the private sector to reduce the amount of energy consumed by new building constructions. Together with the directive from the EU there are also new requirements and demands from Boverket for the real estate sector.  These requirements mostly concern the energy consumption of kilowatt-hour per square metre and that the consumed energy also should be renewable.  The aim of this study is to explain what kind of value municipalities experience in using certifications and environmental investments for new and existing buildings. Within the chapter theory, essential areas are described such as; environmental certification systems, economical viability, proceeds connected to building green, difficulties with building green, the performance of green buildings when affected by the behaviour of tenants and customer value.  The following chapter describes the methodology with which we have conducted this study.

"Hamrén-haveriet" : En kvantitativ studie om personifiering av svenska förbundskaptener i kvällstidningarna

Total amount of words: 15 269.In this essay, the purpose is to examine the personalization of Swedish national coaches during international championships in the Swedish tabloids. Research shows that a leader nowadays is representative for her organization. Therefore it could be assumed that the way the national coach is portrayed can have some kind of effect on the public opinion about the team as a unit and their sport federation in total. This essay is a quantitative study of the sport tabloids Sportbladet och SPORT-Expressen during three international championships: Euro 2012 in football, WC 2013 in ice hockey and Euro 2014 in handball. We have studied the coverage of the national coaches Erik Hamrén, Pär Mårts and Ola Lindgren/Staffan Olsson in contrast to the coverage of their teams in total.The main results are that the national coaches are mentioned in every second article that is written about the national teams during the championships. They are mainly portrayed in a neutral way, even though the coverage of them is affected by the results in the matches.

Är Facebook den nya tidens politiska kanal? : En studie om påverkan genom Facebook.

During the last years social media have developed and become a place where all kind of people can meet and interact with each other without any kind of physical contact to one another. We belive that this development also has made it easier for political parties and organisations to spread their propaganda to the people that uses social media without them knew from whom the information is coming. With this in mind we decided to do a study about the social media Facebook and how the users of Facebook think they are being influenced by political propaganda from organisations and private persons. In our study we decided that we wanted to know why our respondents are using Facebook, if they have payed attention to two political questions, one international question and one national question, that have been noticed recently and if they feel that they are being influenced of political propaganda when they are using Facebook. We have concluded that our respondents, depending on how old they are, do feel that they are being influenced by political propaganda when they are using Facebook. We have also noticed that the younger part of our respondents feel that they are using Facebook because their friends do it and that they have noticed the international political question more than the national political question. In the older category of respondents the reason of why they are using Facebook was to maintain a conection with their friends and they had noticed the national political question more than the international political question. .

Socialt kapital hos Svenska skogsägare : från grannar till sektorsråd

Social capital is a relatively new concept that has received considerable attention in various community branches. The concept relates to people?s contact and relationship with each other, where their social network is seen as a resource. An extensive network of contacts and trust between people often go hand in hand. People with high social capital have high trust in their fellow human beings and vice versa.

Den Kontroversiella Agendan: Om Sveriges och det internationella samfundets utvecklingssamarbete för sexuell och reproduktiv hälsa och rättigheter

The aim of this thesis is to explain what actions Sweden and the international communities have been taking in terms of sexual and reproductive health and rights (SRHR) in order to realize the Programme of Action from the International Conference on Population and Development in Cairo 1994. In a theoretical perspective, donor countries and multilateral organizations are seen as interacting actors involved in global development cooperation. Through applying a human rights approach I will show shortages in terms of supplies to contraception, international agreement on the issue of safe abortions and a new era that comes with new rules for aid and development cooperation. In addition, for human rights to be realized there is the feature of accountability. Without accountability, SRHR cannot be fully respected, guaranteed and protected.

Att läsa texter tillsammans är bra : En studie om läsförståelseundervisning i särskolan med hjälp av strukturerade textsamtal.

International reading comprehension studies, like PIRLS and PISA, state that the reading comprehension of Swedish students has decreased significantly since 2000. As a consequence, the National Agency of Education has made reading comprehension teaching a prioritised field in terms of further education for teachers. There has also been a change in Lgr 11, the national curriculum for compulsory school, where it is stated that teaching in reading strategies shall be a part of the central content throughout compulsory school. When the pupils reach upper secondary school level, reading comprehension education is no longer a part of the curriculum. Today, students at upper secondary school for individuals with learning disabilities currently share the same curriculum as the ordinary upper secondary school.

Norra Djurga?rdsstaden som nollstad : En studie av miljo?projektets sista etapp och dess potential

All around the world more and more people move from rural areas to live in the cities. Because of this, the urban areas have become an important part in the debate about the effects on the environment and sustainability. In many countries word wide initiatives have been taken to build sustainable cities and eco cities, the Stockholm Royal Seaport is one example. The vision for the district is to become a world class sustainable city based on the three dimensions of sustainable development: social, economic and ecologic. The municipality of Stockholm has set requirements for the buildings? energy usage, emissions and amount of waste generated during the building process.

Miljöcertifierade kommersiella byggnader : Undersökning av ekonomisk ansvarsfördelning mellan hyresgäst och fastighetsägare

The Swedish commercial real estate market is in the current situation globally affected and is actively interacting with the rental and capital markets through international tenants and investors who are setting new demands on the property owners. The European Union has set new requirements as well in purpose of reducing humanity?s negative effect on the climate and therefore the international real estate market has introduced Green Building-certificates in order to decrease the real estate industry?s environmental impact.Certificated buildings with low energy consumption are a more common sight in Sweden these days. The development, however, could go even faster if there was not certain difficulties between property owners and tenants. Previous research has revealed that tenants do not always have knowledge about, or may have access to the economic benefits that a green building can provide.

Avena Sativa - En hyperackumulator? : En studie av havres kadmiumupptag

The aim of our research was to investigate if oat is capable of extracting cadmium to such extent that it is usable in decontaminating polluted soils. We grew oat in a hydroponic culture during 28 days in a controlled environment and a total of 30 plants were used. The nutrient solutions were contaminated with cadmium of ten different concentrations after seven days. After harvesting the plants, the roots were separated from the shoots, placed in separate containers and then turned to ashes. The cadmium content was measured three times per sample in an atomic absorption spectrometer.Our results indicate that the ability of oat to extract cadmium from a solution is linearly dependent of the cadmium concentration of the solution.

Tas Nordkorea någonsin på allvar? : En studie av Nordkoreabilden i två svenska tidningar

North Korea has been on people?s minds lately. This essay is a study of what image Swedish press gave of North Korea starting in 1948 and ending in 2011. The study looks at two of the largest newspapers in Sweden, Aftonbladet and Dagens Nyheter.  During the 1950´s the image given was that North Korea was part of the communists, a puppet state of the Soviet Union.

Energisystemanalys av ABB AB LV Motors

With a larger awareness of the climate changes and increasing electricity prices, energy efficiency measures in the industry have become more common. By rationalize the activity and by the same time decrease the emission of greenhouse gases the company can both save money and reduce negative environmental impact. For the Swedish industries the electricity price have traditional been relative low, which has resulted in a considerable larger usage than other European countries. By a deregulation of the European electricity market the electricity price will level off between the countries, which will cause a higher electricity price in Sweden than we are use to. To prevent that the Swedish industry don?t lose competitiveness against the other European countries, it will require energy efficiency activities in all different forms.ABB Sweden has decided to decrease their total energy usage with five percent in two years.

Inverkan på identiteten i en global värld - Hur påverkas svenska diplomater av sitt yrke?

How is the identity of Swedish diplomats affected by living a very international life, regularly moving from one place to another, while their main task is to represent Sweden at all times? How does the national identity relate to the professional and the international identity and what role does the context play in this process? These are the questions asked in this thesis. By interviewing 39 Swedish diplomats and by comparing the responses of the interviews and the theories applied, this thesis will show that it is the context, rather than the time spent abroad that changes their identities and not the least their perspectives of the world. The theories concern intersectional identities, nationalism, context and globalisation. It is from the point of view that identities are constructed and therefore changeable.The diplomats gain a greater awareness of their Swedish identity, wider and deeper perspectives of what it means to be Swedish, but also the advantages that other cultures have to offer.

Vilka skillnader och likheter finns mellan UNHCR:s och UNRWA:s syn på flyktingar? : En komparativ studie mellan FN:s två flyktingorgan

Research about what differences and similarities exists between UNHCR and UNRWA in the opinion of a refugee?This examination focuses on a study between The United Nations High Commissioner for Refugees (UNHCR) and THE United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA). Both organizations are UN-related and are in charge of refugees, however they differ by the fact the UNHCR controls all of the world?s refugees with the exception of the Palestinian refugees, for which UNRWA. The aim of this work will be to examine the definition of refugees as well as their entitlements and in what way they differ depending on which organization they belong to.As theory I have, among others, used Rainer Bauböck?s book ? Transnational Citizenship?.
