Aggregatstabilitet, jordbearbetning och fosforförluster i ett typområde på jordbruksmark :

Large amounts of phosphorus (P) are lost from the arable land due to water erosion. Both phosphorus attached to particles and dissolved phosphorus (mainly phosphate) are transported away with drainage-water and surface runoff. Good soil structure is important in minimizing these losses. In this study, soils from 50 fields were analysed with respect to aggregate stability as measured by dispersion of clay together with the content of total phosphorus (TotP), particulate phosphorus (PP) and phosphate phosphorus (PO4P) in the water phase. All soils were clay soils with clay content varying between 21 and 54%.

Ger olika temperaturförhållanden ¨trade off¨- effekter mellan tillväxt och exokutikulans tjocklek hos Gammarus pulex? En pilotstudie

I rinnande vatten, så som bäckar och åar, har Gammarus pulex en viktig ställning i näringsväven. Arten bidrar till att bryta ner organiskt material och göra energin i detta tillgänglig för andra organismer. G. pulex är dessutom en viktig föda för ett stort antal predatorer. Flera studier visar att G.

Undersökning av miljöstatusen i Gothemsån / Dalhem i anslutning till utsläpp av lakvatten från sopdeponi i Roma 2010

In October 2010 it was discovered that leach water had been released from a waste deposit directly into a ditch during a period from March until October 2010. The river Dalhemsån runs close to the waste deposit, just about 10 meters from the ditch. By studying the benthic fauna it was discovered that the environmental status of Dalhemsån is bad in this part of the river, but the discharges of leachate from the waste deposit does not seem to have deteriorated the water further since May 2010..

Bäddodling av matpotatis :

This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes. Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient. In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.

Analys av vattenkvalitet i ett kommunalt badhus

Bath has been a part of human history for a long time. Today bathing/swimming inmunicipal pools is for people of all ages and it is possible to take swimming courses,exercise or enjoy recreation. The municipal indoor pool of Hogdalen in Sweden wasbuild in the sixties and has had problems with high levels of heterotrophic bacteria. Thefacility has two larger pools, one adventure park for young kids, two smaller bath tubsand a jacuzzi. To improve water quality UV light and coal filter were installed inOctober 2009 to the already existing purification system.

Management på mellannivå-en fråga om ett tudelat arbete? En studie på Trade AB.

Uppsatsens syfte att dels att beskriva vad begreppet management innebär för mellancheferna på det studerade företaget, dels att peka på de konsekvenser som kan följa av detsamma. I uppsatsen har en kvalitativ metod använts med krav på kritisk reflektion. Det empiriska underlaget består av åtta intervjuer med chefer inom ett medelstort svenskt företag. Inom Trade AB råder en tudelad syn på mellanchefsrollen. Denna präglas i första hand av en sälj-och specialistroll och utesluter en integration av chefsrollen, i vilken management inte bara upplevs som personalvård utan som en naturlig del av mellanchefens arbete.

Fosforavskiljning i reaktiva filter vid småskalig avloppsrening

An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.

Fastighetsbranschens kapitalstruktur : En totalundersökning av Stockholmsbörsens fastighetsbolag, hur deras kapitalstruktur har påverkats av övergången till IFRS

Syftet med uppsatsen var att undersöka om det fanns något samband i kapitalstrukturen hos fastighetsbolagen på stockholmsbörsen. Samt att se hur införandet av IAS 40/IFRS har påverkat företagens kapitalstruktur.Författarna valde att göra en totalundersökning för att belysa problemställningen på bästa sätt. Vidare letade författarna i företagens årsredovisningar för att hitta de siffror som behövdes för att räkna ut de relevanta nyckeltalen. De nyckeltal som författarna ansåg lämpliga för undersökningen var soliditet, avkastning på eget kapital, avkastning på sysselsatt kapital och skuldsättningsgraden. På vissa av nyckeltalen ansåg författarna att det fanns ett intresse av att se hur korrelationen och standardavvikelsen såg ut, därför räknades dessa också ut.

Fackförbunden och livslångt lärande : Kritisk analys av livslångt lärande ur ett fackligt perspektiv

Lifelong learning (LLL), a concept dating back to the 1920s, is much used both by the OECD, UNESCO and the EU. But while intergovernmental think-tanks and supranational organisations often use the term in a positive sense, many (not least scholars) are critical of the term. The critique either deals with the lack of a universal definition, that the implicit responsibility for LLL has shifted onto the individual, or that the meaning of the term has shifted from a humanistic one linked to the personal development and a better society to a neoliberal one that involves growth, competition, globalisation and human capital theory. This study is based on interviews with nine trade union representatives on their understandings of lifelong learning. The results showed that while LLL was positively viewed by most, there was virtually no communication vis-à-vis members on the topic, most trade unions have no policy regarding LLL, and responses from representatives were sometimes self-conflicting..

Representeras ditt yrke? : - en kvantitativ studie om vilka yrken som representeras mest respektive minst i facktidskriften DIK-forum

The aim of our study has been to see how DIK-forum represents the occupational groups that are represented in the frames of the trade journal. We have, to find out the phenomenon, done a content analysis by looking into 18 numbers of DIK-forum from year 2006 and 2007. The 18 strategically chosen journals was enough to give us a statistic result that we later on could generalize over those two years of DIK-forum. Totally there were 818 articles, news items and vacant advertisements that made the central point of this study. By these materials have we studied the representation of the occupational groups to find out if there were any over- and/or under represented groups, and also if the publications of the material were directed to the students or to the occupational groups in these trade journals.In our study the results shows that the trade journal DIK-forum does not represent all the occupational groups at the same level.

Terrorism i svenska tidningar : en diskursanalys av Aftonblader, Dagens Nyheter och Svenska Dagbladets rapportering från terrordåden München 1972, Lockerbie 1988 och World Trade Center 2001

Vårt syfte med undersökningen är att undersöka hur de diskursiva praktikerna ser ut för terrorrapporteringen på 1970, 1980 och 2000-talet, vi kommer särskilt att fokusera på beroendeförhållandet mellan terrorism och massmedier. Vi har valt ut tre terrordåd, München 1972, Lockerbie 1988 samt World Trade Center 2001. Vid varje terrordåd har vi tagit två artiklar vardera från tidningarna Aftonbladet, Dagens Nyheter och Svenska dagbladet. Det blir totalt arton artiklar som vi har använt oss av. Terrorism lever i ett beroendeförhållande till massmedia.

Sjuksköterskors erfarenhet av att vårda patienter med självskadebeteende

The Swedish industrial society has left several areas with contaminated soil and water which today is of danger for the environment and human health. One of these areas with contaminated soil and water is the region where the former Glava glassworks operated during 1859 to 1939. The main object in this study has been to study the responsibility for the contaminations according to the Environmental Code. The method used is a qualitative content analysis of relevant literature to answer the following questions:What types of contaminations can be found in the area of Glava glasswork and what health issues can these cause?What kind of activity has been conducted in the area that have caused the contaminations in soil and water?According to law, what are the responsibilities for the contaminations in soil and water at Glava glassworks?The contamination in the region has been confirmed to originate from the glasswork due to the environmental engineering survey made in the area in 2009.

650 stycken citroner, 120 stycken påmerantzer, 200 stycken apellisiner : Vägledning till tullarkiven på Landsarkivet i Uppsala

The organized and controlled form of collecting consumption taxes and toll from the import and export trade goes back to the 17th century in Sweden. The customs administration and procedure were regulated by royal announcements, and the majority of the documents found in the customs archives represent thus records stipulated by such notifications. The customs archives can be used for research on several levels; the announcements reflect currents within both the domestic and foreign politics, while the account lists for financial statistics portray the extent of the trade. The various lists of compilation can be further used to follow for instance the development of different units of measurement, the expansion of tax rates, the value of trade goods or the changes in monetary units or systems. The diaries, architectural plans of the customs offices and maps of the toll areas place the customs officials and their work within the local scenery.The thesis focuses on archives deriving from customs located at harbors and on the Swedish-Norwegian border in the county of Dalarna.

Rådgivare och Pensionssparare : - En studie av interaktionen mellan rådgivare och pensionssparare

From an investigation by Finansinspektionen and KTH (2009) it is apparent that financial advisors and their clients develop relations, believing that they understand each other, while in fact, they do not. The media tends to notice the conflict of interests between advisors and retirement annuity clients. The aim of this study is to create a greater understanding as to why misunderstandings occur between advisors and clients. This will be accomplished by a quality study of how advisors and trade unions assess how the relationship functions. The theoretical part consists of theories concerning relations and uncertainty.

Vinterförvaring av Pelargonium x hortorum :

There are many different recommendations on how to keep pelargoniums over winter, but most of the recommendations suggest ?the higher the temperature, the more light and water the pelargonium needs?. The purpose with this paper is to try to explain the best and the worst results that are achieved with different storage alternatives of zonal pelargoniums. The results are based on an orientating investigation carried out in January-February, and a questionnaire that members of the Swedish Pelargonium Society answered to. Both the orientating investigation and the questionnaire showed that zonal pelargoniums are best stored light and cold but frost free. They should be irrigated according to their needs which is when the soil is dry, about every second to third week. Zonal pelargoniums are very resistant to drought and can survive without water for at least 44 days, both when kept under light and cold as well as under light and warm.
