Brolaster enligt Eurocode En jämförelse av dimensionerande brolasters påverkan enligt Bro 2002 och Eurocode

AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.

Hållbar vattenförsörjning i områden med vattenbrist : Sustainable water supply solutions for areas affected by water shortage

In some coastal areas in Sweden water shortage sometimes appears because the withdrawal of groundwater is greater than the groundwater recharge. It creates a situation where the available groundwater is insufficient to support residents and businesses with drinking water. The high withdrawal of groundwater also creates a risk for saltwater intrusion to drinking water wells. The problem most commonly occurs during the summer when the groundwater recharge is low, but the population is high, due to tourism and summer residents.The purpose of this study was to investigate how local water supply in areas affected by water shortage can be solved as sustainable as possible. The work was divided into three parts where the first part comprised of a literature review on water systems in which four different options were investigated: artificial groundwater recharge, rainwater harvesting, desalination and water reuse.

Solvärme på Utö

The guest harbor on Utö, Utö Gästhamn, is currently using electricity for heating all of the water used in the showers and taps. Because of the large amount of visitors, especially during the summer months, the hot water usage gets very high and that is also the case for the electrical bills. During the year of 2011 the cost of electricity for Utö Gästhamn reached a total of 257 500 kr. Out of these 257 500 kr approximately 142 000 kr, 55 % of the total cost, were because of the water heating.The report is the result of a cooperation with Skärgårdsstiftelsen, the Green Islands-project and Utö Gästhamn where the mutual goal is to dimension a solar energy system, to promote the sustainable development.Initially the different techniques for the solar energy system are researched. The techniques are plane solar collectors, evacuated tube collectors, pool collectors and photovoltaic cells.

"Hon är undantaget som bekräftar regeln" : Om hur bekönandets mekanismer påverkar utrymmet för kvinnor och män på ett medelstort företag i Sverige

AbstractThis paper is based on a research conducted in a medium sized company, situated in Sweden, with the intent to study possible connections regarding views of gender and the existing sex segregation within the company. How is gender constructed, and does it exist representational ideas of the sexes, that leads to restrictions for men and women to be working within different areas of the company? Why are there such few women working within the company? Through five interviews with employees within the company, three women and two men, I found answers to these questions. My thesis and the specific questions were categorized into three different themes. The first theme aims to understand the interviewees? discussions of gender and labour.

Nitrogen flow in Scania : substance flow analysis on a regional level

In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. This is linked to a series of environmental problems such as eutrophication, acidification, global warming and smog. The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society.

IT-verktyg och kommunikationinom globala projekt

Many companies with expansion plans may eventually need to take a decision whether tomove parts of the organization abroad or not. One example is how Swedish companies? placesits production in Asia where labor is cheaper, but at the same time wants to use Swedishengineers. The communication possibilities today makes it no longer necessary to travelacross the world to have a meeting, and questions can be answered in a matter of minutes.This means that a company that is spread out over the world still can communicate betweentheir employees.When participants in a project are spread out over the world, and can?t meet in person, it iseasy for problems to appear.

Det gemensamma bästa kan inte förutsättas : En berättelse om Grupptalan mot Skandia

The subject for this paper is the Class Action against Skandia Association, a civil organization formed in 2003 with the aim of claiming compensation for some 1.2 million life insurance customers. The background to its formation was one of the largest financial scandals in Sweden in recent times, involving a number of questionable affairs within the insurance corporation Skandia and its subsidiaries, most notably the life insurance company Skandia Liv. The interests of both the stake- and stockholders of the company seem, in certain ways, to have been grossly misrepresented. The scandal, as well as the reaction it spawned, pose a number of questions. In this study, we focus on two: a possible, and in many ways apparent crisis in the representation of interests in Swedish society, and the role of civil society in upholding the balance between these interests.We argue that what is often held to be the ?greed? or ?immorality? of individuals in scandals such as Skandia is, to a great extent, a mere reflection of the ?rational? underpinnings of modern-day capitalism.We find that trust has been a key mechanism of control in the relationships between consumers and agents in pension and life insurance markets, and that ?the Swedish model? that distinguished post-WWII Swedish society was a model heavily based on trust towards existing models of bureaucratic governance.

Incitament för energibesparande åtgärder i den byggda miljön

More efficient energy consumption is essential to secure a sustainable future, not least within the building and real estate sector which answers for approximately 40 % of the EU countries total energy consumption. One part of EU: s work to reduce the energy consumption is the directive on energy performance of buildings which among other things have lead to stricter demands on energy performance in new and renovated buildings.One of the difficulties with making buildings more energy effective is that it often demands big investments and although it results in lower operating costs the extent of these savings and therefore also the repayment time can be difficult to decide beforehand. To make it interesting for property owners and also tenants to invest in energy efficient buildings powerful incentives are needed. Favorable loans to energy efficiency projects are one example of governmental instruments that have been tested in other European countries with good results.Reduced operating costs appear to be the main incentive for property owners to make their buildings more energy efficient. The best result of an energy efficiency project is usually achieved by cooperation between property owners and tenants but in order to make that interesting it is important that both parts can profit from the savings.

Comparison of three IVC systems for mice, with focus on growth and nest building in juvenile mice

Today the individual ventilated cage system (IVC-system) is the most commonly used system when housing rodents. IVC systems are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare for two different strains of laboratory mice (NMRI nude mice and C57BL/6NCrl mice) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. 108 mouse pups from each strain (in total 216 mice) were selected after weaning at an age of three weeks and tested during 5 weeks.

Miljösystemanalys av alternativa avloppssystem i ett urbant område ?Svartvattensystem : Skogaberg ? Ett pilotprojekt i Göteborg

Starting point to this Paper is the idea and wish to adapt the society and its different activities to a recycle society. A building area in Göteborg is planned and investigated for such adaptation. In the district named Skogaberg, about 130 households totally are planned from what 20 are blocks of flats. The idea with this project is to constitute an alternative sewage system, a Blackwater system, were the fractions of most nutrients and least pollution are separated, taken care of and utilised. The aim is to get a market and use the nutrients of the organic waste from the household in agriculture use.

Byggnadens andra skepnad : En anpassning för att möta samhällets behov och krav

Population growth leads to an increased need for new buildings, both residential and commercial. The regulations of structural design also changes with time. From a sustainable community perspective it may be profitable if existing buildings, that no longer performs their original function, are reconditioned. Knowledge and understanding of the surroundings of the residence must be available. Regulations regarding accessibility to all has increased.

Elever med läs- och skrivsvårigheter : En studie av det stöd som erbjuds i olika skolor i en Stockholmsförort.

Syftet med denna studie är att i en kommun söder om Stockholm undersöka det eventuella stöd som elever i år 1-5 med läs- och skrivsvårigheter och dyslexi erhåller. Studien är baserad på en enkät som skickats till samtliga speciallärare och specialpedagoger i den aktuella kommunen. En telefonintervju med en person på kommunnivå genomfördes för att komplettera undersökningens resultat. Studien visar att alla skolor utom en har speciallärare och specialpedagoger till elevernas förfogande. Rektorn på varje skola ansvarar för stödundervisningen, då kommunen sedan en tid decentraliserat ansvaret för detta.
