Black nightshade (Solanum nigrum L.) is a major problem in gardenpea cultivations contracted by Findus AB, a Swedish food processing company. The main problem is that the nightshade berries contain solanin and, thus, are not tolerated in the marketed product, which is fresh frozen peas. In addition, berries have the same size and color as the peas and cannot be separated at the factory. Black nightshades have the last ten years become a more common weed in field grown vegetables in the southern parts of Sweden. This MSc thesis presents an experiment conducted in 2005, aiming at developing a tool for predicting the need for control of black nightshade in peas.

This thesis is about Christmas tree plantations in Sweden, and if its profitable to produce Christmas trees in Sweden. Sweden has 4,3 million households, 3 million of these households buys Christmas trees. 80 % of these Christmas trees are Norway Spruce (Picea abies), which is the most common Spruce in Sweden. Every year over 170 000 Christmas trees are imported to Sweden. The main import comes from Denmark.

Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

Biodiversity is essential for human well-being and it is defined as the genetic variation within species and the variety of species and ecosystems. Biodiversity provides several ecosystem services which are necessary for human beings but there are different threats towards the biodiversity. The biodiversity linked to the forest in Sweden are threatened, about 50 % of the red-listed species in Sweden are associated with forests. This is linked to the commercial exploitation of the boreal forest in Sweden which started 200 years ago. The forestry the last 50 years, with clear-cuts, have contributed to a fragmented forest landscape.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

Today Scania give a high priority to the continuous improvements on the quality of their vehicles. To follow up the flaws in product quality, which are recognized by the repairs at the local workshops, material requests are carried through to be able to analyze the defects at the plant in Södertälje ? in purpose to improve the product quality. The material requests are also carried through to compensate the workshop for their expenses and to check that they are working according to the company?s warranty manual.Due to local routines and different distribution structures at the different markets the lead times and the costs caused by the flow of material are hard to estimate.

Equality between men and women has as an ideal won an increasing impact on the contemporary Swedish society and has established as a factor influencing all areas of society from politics to business and private life. The focus of this essay is to explore the impact of equality on hegemonic masculinity and relations of masculinities. The aim of the essay has moreover been to investigate the consequences of an increased focus on men and critique of masculinity due to a growing influence of feminism and women?s movement in Sweden. The study is based on interviews with four members of staff working in a men?s clinic for sexual and reproductive health in Stockholm, Järva Mansmottagning.

The Baltic Sea is threatened by eutrophication that largely is due to nutrient leaching from farmland within the catchment area. To solve this problem the surrounding countries cooperate within various configurations such as HELCOM and the EU-financed project Baltic Compass. Poor manure management in Russia has been discussed frequently the last couple of years. A literature review of different types of reports and legal acts is the core of this degree project which has been performed in connection to two ongoing research projects financed by EU (Baltic Compass) and SIDA. It is supplemented with interviews with Swedish agricultural consultants and travel reports from two occasions when I had the opportunity to discuss with Russians active within the agricultural sector. Different hypotheses were investigated and discussed. The environmental debate in Russia is quiet and there is a widespread approach that economic profit always trumps environmental concern ? a Soviet heritage that influence the Russian agriculture considerably. The Russian legal acts on stable manure management focus mainly on sanitary questions and only secondary on nutrient leaching.

This bachelor?s thesis is a study that examines cactus groups in Sweden from a heritage conservation perspective. Through interviews and an analysis of both historical and modern literature, the research explores why cactus groups became popular and what is required to preserve those still in existence today. A recurring challenge has been the lack of comprehensive source material, leaving some questions open for further research. The study focuses on four cities?Norrk?ping, Skellefte?, Varberg, and V?xj??that have maintained their cactus groups for nearly a century.

Alien plants that have intentionally been introduced to an area for cultivation in public or private gardens constitute the primary pathway of introduction for invasive alien species that spread into nature. Garden owners want species that have satisfying characteristics, these characteristics are often also linked to plant invasiveness. Thus, the horticulture industry plays an important role by making scientifically based decisions and phasing out invasive plants and replacing them with alternative species with satisfying characteristics, but low risks of becoming invasive. This thesis aimed to examine the sale of and the attitudes towards alien plants in the horticulture industry in Sweden. Alien terrestrial plants identified to have a severe risk, high risk or potentially high risk of spreading and becoming invasive according to ArtDatabankens assessment, were examined to see if they were for sale.

In Sweden there are 1894 small-scale hydropower plants in operation, which together generate 4.3 TWh of electricity per year according to Swedish hydropower compound (SVKF, 2011). This corresponds to the annual consumption of about 860,000 Swedish households (based on an annual consumption of 5000 kWh). In the mid-1950s there were around 4000 small-scale hydropower plants in operation in Sweden before cheap fossil fuels and uranium competed with them, in the current situation only 1,894 of these are in use. If slumbering small hydropower plants once again would be taken into use and some new ones are built, we would be able to extract about 7 TWh of renewable electricity from these annually in Sweden, representing about 1.4 million households.The thesis intends to calculate and construct a hydroelectric power plant at the existing dam in Olofsfors and give suggestions on how the power station should run during the time that fish migration is greatest in Leduån.The turbine and generator to the station in Leduån at Olofsfors is designed by the height of the fall and the water flow through the dam. The turbine selected for the station is a CK-1000RM turbine with a 4-pole 250 kW generator from Cargo & power turbine Sweden AB, which is expected to deliver 1.2 GWh per year.

The situation of officials of public and governmental organizations have been recognized as increasingly risky, in which the influences of both threats and violence have become an issue that administrators have to manage. Experiences of feeling threatened in their workplace or in their professional lives has been marked by an increased number of reported cases in the work environment authority. Common to the problems faced by many agencies and important associations that dealt with its often derive personal and sensitive issues. The purpose of this study is to highlight how veterinarians and animal welfare inspectors on the counties of Blekinge, Kronoberg and Kalmar experience the interaction of regulatory and prohibition cases. Länsstyrelsen is the one that can decide what is to happen to an animal that has been kept under bad conditions.
