Våtmarker för näringsretention i Lillån : var bör de ligga och vilken effekt kan vi förvänta

Construction of wetlands in the agricultural landscape may reduce nitrogen and phosphorus transfer to streams, thereby reducing the eutrophication of lakes and seas. The agriculturalstream Lillån, a tributary to stream Sagån, ends up in Lake Mälaren and is transporting large amounts of these plant nutrients. The aim of this study was to estimate how hypothetical wetlands of different size and location may reduce nitrogen and phosphorus load from stream Lillån. Estimated nutrient Retention in several small wetlands was compared to Retention in a single large wetland based on existing data from the agricultural stream and from a nearby smaller stream. Retention in the stream was suggested to decrease along with the nutrient concentration in the water.

Combining the Concepts of Fear Aroual and Customer Satisfaction & Retention - An Ethnographic Case Study on Krav Maga

The purpose behind this study is to explore and explain the role of fear arousal when combined with the concept of customer satisfaction and Retention in one marketing strategy. The major theories applied are the concept of fear appeals and the concept of customer satisfaction & customer Retention. We chose to conduct our research through an ethnographic case study of KM. We did a qualitative study where we collected 10 interviews and we conducted observations. Our empirical data consists of academic articles from scientific journals, interviews andobservations.

En studie av retentionen i floden Oder och dess avrinningsområden, Polen.

Nutrient enrichment is the main cause of the increasing eutrophication process in the Baltic Sea during last century. A prerequisite counteract this process the load of nutrients to the Sea must be investigated. The large contribution of nutrients to the Sea is caused by emission from the rivers within the drainage basin. For the total emission of nutrient into the Sea the Retention process in the rivers has big influence. This process in the river system has been assumed as a not important part of the nutrient cycle.

Fissurförsegling på studentklinik : Kartläggning av retention och kariesförekomst

Syftet med denna studie var att kartlägga Retentionen av resinbaserade fissurförseglingar på sexårsmolarer utförda på studentklinik. Karies registrerades även på övriga sexårsmolarer. Materialet utgjordes av 51 barn födda år 1999 eller 2000 med minst en fissurförsegling på sexårsmolaren utförd av tandläkarstudent. Fissurförseglingen skulle vara utförd i Delton® och ha en minsta uppföljningstid på ett år. Data registrerades från journaler avseende allmänhälsa, medicinering, kariesdata och riskgrupp.

Trädens utveckling efter att de har lämnats som naturhänsyn : tillväxt, mortalitet och strukturell förändring 6-18 år efter avverkning

Today green tree Retention, together with leaving dead wood, is a common practice with the aim to reduce negative impacts on biodiversity and environment due to clear-felling. To better understand whether this conservation practice also makes a long-term difference, it is important to know what happens to these trees after harvest. Few studies have made an assessment of what happens to Retention trees over a longer time period. In this study I inventoried Retention trees that were left at clear-cuts six, twelve and eighteen years ago. I carried out a re-inventory of 57 Retention patches (divided into free-standing tree groups, small swamp forests and edge zones) and free standing dead trees, spread over 25 previous clear-cuts in central Sweden.

Varmhållen och kyld skolmat : En jämförelse med fokus på energianvändning mot bakgrund av livsmedelssäkerhet och näringsretention

The aim of this report has been to investigate the use of electricity energy before and after a conversion of foodservice. The ambition was also to highlight the food safety and the Retention of nutrients in relation to the conversion. The methods being used were qualitative interviews, case studies, study visits and literature. The equipment and the use of energy was the same in 2008 as in 2011 for hot-holding of the tested component, sauce with ham. The chilled system used more than three times the energy and cost for one portion than one portion in the hot-hold system.

Low-Skilled Employee RetentionPractices in the Fast Food Industry : A study of retention practices within the Verhage FastFood franchise

Employee turnover can cost an organization a significant amount of money. In addition, Retention of employees can beneficial towards to an organization as it e.g. allows to save costs related torecruitment and training of new employees. The fast food industry is recognized as an industry which employs low-skilled employees and is especially in the United States known to be prone to high employee turnover. With regards to Europe, only little information is available in the field of low-skilled employee Retention in the fast food industry.

Referensvåtmarker för uppföljning av växtnäringsretention i anlagda våtmarker

One of the environmental problems today in seas, lakes and streams is eutrophication. This is often caused by nutrients such as phosphorus (P) and nitrogen (N) that leak from agricultural areas. A measure to partly prevent the nutrient discharge is to construct or restore wetlands.In order to control the efficiency of nutrient reduction of existing wetlands in the county, the administrative board in Västra Götaland wants to find different criterias for reference wetlands. These reference wetlands should represent other wetlands and be used in future evaluations of reduction of nutrients and design of constructed wetlands. According to the administrative board in Västra Götaland the reference wetlands should have a catchment area of about 50 hectare consisting of at least 70 % arable land, to represent wetlands created to remove nutrients.

Translokation av större vattensalamander : -bevarandestrategi eller riskåtgärd?

This study evaluates the Retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

Retention : Varför stanna när möjligheterna är oändliga

Bachelor thesis, Degree of master in Science and Economics, School of Business and Economics at Linnaeus University, Management, 2FE01E, Spring Semester 2013Author: Johanna Björklund, Sarah Gustafsson and Sofia NicklassonMentor: Anders HytterTitle: Retention: Why stay when your options are unlimited? Background: Employee turnover is a problem today, and companies face increasing challenges when it comes to retain employees within the organization, so called employee Retention. This is a present concept and theory holds that more organizations realize that they need to put more focus on Retention as one of their business goals to remain competitive. It?s important that organizations understand individuals' different needs and the factors that make them satisfied in their professional life.

Uppfångning och kvarhållning av 134Cs och 85Sr i olika växtutvecklingsstadier

Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in the event of rainfall. An increased level of radioactivity in the plants may occur due to interception and Retention of the radionuclides. If the content of the plants is above the threshold limit value, entire yields may have to be destroyed. In order to prevent contamination or decrease the content countermeasures can be taken. The impact of the biomass, leaf area index (LAI) and growth stage of the plant on the interception and Retention is important to know in order to decide which countermeasures to use. Weather may also be an important factor. In this work the interception and Retention of 134Cs and 85Sr by spring wheat, ley and spring oil-seed rape was studied.

Förslag till kväverening i Forsåsystemet genom våtmarksetablering

The last hundred years humans have drastically changed the amount of available nitrogen in nature. Today human activities release twice as much available nitrogen as all natural processes are doing together. We also have degraded nature´s possibilities to take care of nitrogen through the draining of wetlands and straightening of rivers. In order to regain the potential of nitrogen Retention in the water systems there now requires a reshape of the landscape we live in. A planned expansion of the mining activities in Garpenberg, Dalarna, would double the content of nitrogen in the waters below the mine.

Naturhänsyn på slutavverkade hyggen i Östergötlands län.

95% of the productive forest land in Sweden are now being exploited for forestry. The new Forestry Act of 1993 equate the goal of production and the environmental goal which means that the objective for forestry is a sustainable yield, while the biological diversity must be preserved. Recent years results from the inventories of the Board of Forestry show declining trends in how nature conservation aspects taken into consideration at the felling sites.The aim of this study is to investigate what happends with the nature consideration taken at felling sites in the long run. 20 final fellings in the county of Östergötland were re-inventoried 7-9 years after final felling. These felling sites had previously been inventoried before final felling (P0) and one year after final felling (P1) in the inventory Polytax by the Board of Forestry.
