Detta examensarbete handlar om Rain Garden. Arbetet vänder sig till dig som har ett intresse för dagvattenhantering. De som söker djupare kunskaper i ämnet kan använda sig av förteckningen över referenser. I framtiden förväntas klimatförändringar med höjda temperaturer och ökade nederbördsmängder som följd. Samtidigt växer städerna vilket leder till att andelen hårdgjorda ytor ökar och den naturliga infiltrationen minskar.

Globally, coastal ecosystems like mangrove forests, sea grass meadows and salt marshes are well known for their ability to capture and store atmospheric carbon effectively. In Sweden, there is still limited knowledge about local coastal ecosystems with similar functions, with alder swamp forests being an interesting example. Therefore, this study aimed to increase knowledge of the factors that can contribute to the potential carbon sequestering ability of alder swamps. Vegetation data and sediment samples were collected from a total of 37 sampling plots across four alder swamps in Bohusl?n on the Swedish west coast.

The objective of this work was to evaluate and compare three field methods for detection of mastitis, California Mastits Test (CMT), DeLaval cell counter DCC (DCC) and FMA2001 Farm Milk Analyzer (FMA2001). Furthermore, to investigate at what cell count level clinical symptoms of mastitis are seen, and finally to check if the clinical findings and cell counts could be related to bacteriological findings. DCC and FMA2001 are new analytic instruments to be used on dairy farms for detection of mastitis. CMT has been a widely used cow-side-test of milk quality in mastitis control efforts, but it cannot be used for estimating cell counts in scientific studies or investigations. Two hundred and eight quarter milk samples from 52 cows were analysed with DCC and CMT, and 168 of these samples with FMA2001. Microbiological examination was done on 38 milk samples with CMT scores of 4 and 5.

Heath star moss (Campylopus introflexus) is an alien species in Sweden and is currently classified as composing a "very high risk? of becoming invasive in the country according to SLU, and has in several parts of the world taken over large areas in a short time. The moss is characterized by its preference for disturbed and burned land, something that occurs on the heathland in the Sandsj?backa nature reserve, when burning for nature conservation purposes is carried out annually. Sandsj?backa's heathland is a valuable ecosystem and is one of the few heathlands in a favorable condition that remains in Sweden after strong reforms in modern agriculture in the last century, which led to forest succession of these cultural environments.

The numbers of natural disasters caused by extreme weather are increasing through out the world. A large majority of the research concerning the climate shows that this is a trend that can be expected to continue. At the same time the urbanisation is increasing more than ever and for the first time in history more than fifty percent of the population lives in a city. How we build these cities will have a crucial importance for our adaption to the new climate. In Sweden, our capacity for an adaption are high because of our economic situation as well as our rather well built society.

Selenium (Se) is an essential trace element that is involved in several physiological functions in mammals. Mostly, Se is bound to proteins, many of them with enzymatic functions. A group of seleno-depending enzymes, glutathione peroxidases (GSH-Px?s), are important as antioxidants and protects against free radicals. The activity of GSH-Px is strongly regulated by Se storage in the liver.

Most of the city of Uppsala rests on postglacial clay with a varying content of sulphur. The sulphur occurs naturally in the clay in reduced form as sulphide and the clay is for that reason usually called ?sulphide clay?. Excavation during construction activities gives rise to large amounts of excavation material, of which the sulphide clay is a considerable part.When the clay is exposed to air and water, an oxidation of the sulphides occurs which may produce an acid leachate and the mobilisation of heavy metals bound in the clay or underlying material. The aim of the work has been to improve our understanding of the behaviour of sulphide clays and produce a basis for risk assessment in the future handling of excavation material with high sulphide content.

Det kommer fler och fler rapporter om översvämningar med katastrofala konsekvenser som följd. Klimatforskare menar att regnmängden i Skåne förväntas öka samtidigt som det sker en enorm exploatering där städerna förtätas och gröna ytor med naturlig infiltrationskraft minskar drastiskt. År 2000 infördes ?Vattendirektivet?. Det är EU:s ramdirektiv för vatten som syftar till att skydda och vårda våra vattenresurser i form av sjöar, vattendrag, kustvatten och grundvatten inom EU.

The study describes six upper secondary school students? thoughts of and stories about mentors and mentorship in secondary school. The mentorship has been studied with a hermeneutic approach from a narrative pupil relational perspective, which is influenced by the phenomenological humanity perspective. The aim of this study is to describe a few pupils? life worlds and to try to interpret how they describe and explain their own behavior related to mentorship and their mentors.

The cardiovascular system is one of the three major body systems. When an animal in a critical state arrives at the animal hospital, it is important to know the normal parameters in order to assess the patient?s cardiovascular status. Triage is a process where you considerate the patient?s condition instead of check in time, or other criteria.

In coastal wetlands carbon/organic matter can be stored for long periods of time thanks to, among other things, the presence of water which slows down the decomposition. Because of this, restauration and management of such habitats have the potential to decrease the emission of greenhouse gasses and help mitigate climate. Internationally these environments are called ?blue carbon? ecosystems. In Sweden, alder (Alnus glutinosa and Alnus incanata) covered wetlands along the coast is a nature type that potentially could function as a ?blue carbon? habitat.

During the last years, meticillin resistant Staphylococcus pseudintermedius (MRSP) have caused an increasing number of infections in Swedish dogs. MRSP is resistant against a majority of the antimicrobials available for dogs in Sweden, making it difficult to treat the infection. Our knowledge of the bacterium is limited, making it hard to handle infected dogs in a proper way. The aim of this study was to investigate for how long time dogs, who have an infection caused by MRSP, become carriers of the bacterium. Other factors like treatment with antimicrobials, the correlation between clinical symptoms and carriage, common diagnoses and institutionalization where also looked upon.

24 years have passed since the Chernobyl accident when radionuclides were spread over largeareas of Europe, including the Scandinavian countries. Today, measurable activities of 137Csare still observed in many Swedish ecosystems.Ants (belonging to the order Hymenoptera) are social insects which collect organic materialfrom a large area around their nests. This study focuses on the 137Cs activity in ant nests andthe cesium accumulation in these nests. The aims were (1) to estimate the 137Cs fall-out in1986, (2) estimate the radiation exposure of ants and (3) find how 137Cs is distributed in an anthill. Seven ant hills (occupied by the species Formica polyctena) were studied near the villageof Hille, situated north of the city of Gävle in central Sweden.

In search of Umbilicaria subglabra In Sweden Umbilicaria subglabra has its only known occurrence in Lybergsgnupens nature reserve in the county of Dalarna where it has been found only once in 1936. It was found on the east-facing rock spur, approximately 650 meters above sea-level. The lichen is now red-listed as Regionally Extinct (RE) in Sweden. The aim of this study was find U. subglabra.

Today we keep our horses in a way that is easy for us humans but may not always be the most optimal way for the horse. Often the housing of the horse prevents the horse from performing behaviours that they have natural needs to perform. It is not unusual that animals that can not adapt to their environment develop abnormal behaviours. Many of our stabled horses therefore develop some kind of stereotypic behaviour. This study was made in purpose of comparing the behaviour of a weaving horse to two non-weaving horses under similar conditions, where one of the horses was stabled next to the weaving horse and the other horse was stabled further away in the same stable. Seven weaving horses were included in the study.
