The park at Djäkneberget and its surroundings is a beloved area in the city of Västerås. The area is one of the most popular sites for outdoor life and recreation of all sorts and it attracts different kind of people at different times during the day. The park includes a pond-system where protected species of frog and toad live and breed. These animals have been the objects for many discussions concerning whether to explore the closeby areas or not. The prospected area is situated just next to one of the main ponds and consists of valuable foundationwalls were experts predict that the frogs and toads spend the winter. The municipality has now decided to restore this area to parkland. Because of the areas fascinating history I have chosen to do some research and give a short resume about it. For example are the existing park of Djäkneberget and its founder described together with a short description of the watersystem with the watertower that is situated in the area.

Regulation of rivers by dams and reservoirs is a good example where anthropogenic impact could be considerable both in the local environment, but also has major implications upstream and downstream. This study was accomplished as a literature study of the river Nile, which is extremely important for water supply. The purpose of this study was to investigate the consequences of the construction of the Aswan High Dam, to obtain a consistent flow for water supply, irrigation and power generation in Egypt. Since Egypt has a very hot and dry climate large amounts of water in reservoir is lost to the Nubian aquifer system and by evaporation. The consequences from constructing the dam are considerable.

An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.

Metso Paper in Karlstad is acquiring Kvaerner Pulping and Kvaerner Kamfab, also located in Karlstad. Following this acquisition, there are going to be changes in the organizational structure and some employees might even loose their jobs. There are guidelines from the European Union how to handle situations like this, the purpose of these are to protect the employees. There are also Swedish laws that regulate the protection of the employees when a company is acquired, who is going to keep their job and who is to be made redundant.The transaction between the companies is large why they need an approval from the European Union. The European Union has certain demands for the approval.

In recent years, several scandals have been revealed where public employees been involved. Some researchers argue, moreover, that the NPM's rampage has led to an increase in the risk of corruption in public administration. The Regulation on Internal Control shall, according to the government, lead to adequate protection against corruption by analyzing and managing risks. However, Riksrevisionen have criticized the authorities' protection against corruption to be too unstructured and unsystematic. In addition, they questioned whether the regulation really has significance in the work against corruption.

The government regulations for energy use in buildings will be tightened in the future. At the same time the interest in environmental classifications and certifications of buildings is increasing. This has meant a new situation for solar energy. The designs of solar heating systems are often based on experience and/or rules of thumb, rather than calculations and simulations. This thesis examines whether simulation tools, in this case Polysun, are useful in this work.

During the last part of the 20th century many companies has started to build their organizations on knowledge and information instead of manufacturing of products.  Today it is easier to communicate and spread information. At the same time the numbers of untraditional employments like temporary employments and workers from staffing agencies are increasing. Many organizations have higher employee turnover now than before. This allows more people to have access to confidential information, whose spreading might cause great damage for the employer.

The fact that a duty of loyalty within the Swedish company law exists should be regarded as indisputable according to the Swedish doctrine, but its content and scope is however more severe identified. As the duty of loyalty is not regulated in the ABL and the fact that there are not many precedents in this area, means that it is difficult to know the boundaries of the company management´s duty of loyalty. It is also unclear whether the company management´s duty of loyalty to the company also is targeting the shareholders. It is this issue that we intend to discuss in the final chapter of this thesis. In order to answer our questions, we will in chapter two to six give an account of the foundation of the duty of loyalty and thereafter describe the management's duty of loyalty to the company.

This report has been done in collaboration with SCA Skog, Norrbottens Forest Management Area. The purpose of the survey is to try to find out what the forest owners who either live in Norrbottens Forest Management area or outside but has their forest holdings in the administrative area has the vision of SCA Forest and their forest services offered by the administration. But also to find out the presences of other timber buying players who procures timber in the administrative area. This study seeks to determine if there are deficiencies that may need changes or improvements to the prevailing conditions in Norrbottens management area. The literature study is about how to design a questionnaire based on what you want to know and what to consider in order to eliminate the problem of constructing a questionnaire. A questionnaire was sent to 400 randomly selected forest owners who have their forest holdings within SCA Forest Norrbotten Management Area. And of the 400, it was 181 respondents with 39 women and 138 men.

Calcareous fens constitute a specific habitat which is uncommon in Europe and protected by the EU habitat directive due to its importance to several threatened species. Hagebyhöga in Östergötland is a calcareous fen habitat included in the Natura 2000 Networking Programme. Adjacent to the existing fen, a degraded fen area is situated. The area has been used for agriculture for several years but is now going to be restored to its former state by the county administrative board of Östergötland.When working with restoration of degraded fen areas it is important to aquire knowledge about the chemical soil conditions. Plant growth limited by phosphorus and low fertility are characteristic conditions for calcareous fens, whilst arable land usually is highly fertile and limited by nitrogen.The purpose of this study is to bring forth useful knowledge for restoring the degraded calcareous fen of Hagebyhöga.

Burnt Spine-cap Sárcodon fuligíneovioláceus are one the most endangered mycorrhizal fungal species in Europe. They have their main distribution in Sweden. It form mycorrhiza with pine and dependent on limestone, which makes it connected to a rare environment. It has therefore been important to study the ecology of it further and to recognise the requirement it has on the environment more accurate and what it need to establish in a new area. In this study, 31 of 34 known sites in Sweden was visited and studied in field and their history analysed through aerial photographs.

The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is collected and checked.

A great number of tourists visits each day the Fox Glacier in New Zealand and are subjected todangers such as jökulhlaups. This phenomena can occur suddenly and in a destructive way when abuilt up of water suddenly bursts and releases large amounts of water. This is well known to happen atthe near by Franz Josef Glacier which has similar settings to Fox Glacier, but sparse previous researchon the subject indicates different results of whether jökulhlaups are present or not by Fox Glacier. Thisthesis therefore aims to study the conditions for jökulhlaups at the glacier. This is done by remotesensing and field observations of the sandur in the Fox Glacier Valley, qualitative interviews andliterature studies with a comparison with Franz Josef Glacier.

Modern forestry requires a high degree of machine traffic for clear felling and scarification operations. The machines most frequently used are big and the traffic often results in tracks on the forest ground. There are many small streams running through a forest, in connection to logging operations, machines might cross these frequently. These crossings could result in the erosion of fine particulate inorganic matter, which ends up in the stream. The aim of this thesis was to give a general description of small forest streams of order-one in the county of Värmland and to determine the frequency of machine tracks in small streams.
