Tillämpning av en markprofilmodell för hydrologiska beräkningar i avrinningsområdesskala

There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..

Samiska kvinnors levnadsvillkor i kulturen och rennäringen

Previous research often includes juridical, political, economical and historical aspects of the Sami population. The research about the Sami women are limited therefore is was important to investigate the living conditions of the Sami women. The purpose with the study was to investigate the living conditions of the Sami women from a culture- and reindeer-herding view in relation to social gender and the majority society. Four individual interviews were performed with women who worked with reindeer-herding in the Sapmi area in north of Sweden. The interview guide was semi-structured and the data were analysed with the phenomenological method Interpretative Phenomenological Analysis, which has a focus on subjective experiences.

Djurägarbehandlingar inom renskötseln :

The aim of this study was to document treatments of sick and injured reindeer in Tornedalen and the area around Gällivare. I also wanted to find out the basis for the treatments, how they are considered to work and if they agree with established veterinary science. The occurrence of ?folk remedies? was especially studied. In all, 40 reindeer owners were interviewed.

Företagens aktuariella antaganden - vilka faktorer påverkar dem?

The purpose of our essay is to study the institutional-, demographic and accounting theoretical factors that influence an organisations actuarial commitment.The research was performed through a web based survey, with complimentary telephone interviews, directed to companies listed on Stockholm Stock Exchange A- and O-list on the 30 of November, 2003.Our data was analysed with a Median test, Kolomogorov-Smirnov test, T-test and a Mann-Whitney test. The purpose of the Mann-Whitney test was the low number of respondents that took part in the research. The Kolomogorov-Smirnov test was done to determine whether the population variances was equal or not. The data showed that organisations with a majority of female employees assume a lower salary increase, and a higher average age than other companies with a male majority. Only 2 of 11 hypothesis can be accepted as temporary truths but several other visible relations are indicated in our research, but can not be statistically proved.We think that the major problem with our is the time it was performed.

Roten till det onda : en studie i häxmotiv, kvinnlig sexualitet, husmoderlighet och moderlighet i Ulla Isakssons historiska roman Dit du icke vill

Ulla Isaksson (1916 ? 2000) wrote many novels, often with a woman or several women as protagonists. In Dit du icke vill (?Where Thou Willst Not?) from 1956 she depicts a crisis of faith in a woman, which would not have been successful had she chosen a contemporary setting. She uses an adequate historical framework, the prosecution of witches in Sweden in the 17th century, well documented in reliable sources.

TID EN RISKFAKTOR FÖR PATIENTSÄKERHETEN

Bakgrund: Varje år drabbas ca 100000 patienter bara i Sverige av någon form av vårdskada. Globalt sett är den vedertagna siffran ca 10 % av inläggningsfallen. Då sjuksköterskan spenderar mycket tid med patienter har han eller hon ett stort ansvar för patientsäkerheten. Syfte: Syftet med litteraturstudien är att undersöka hur sjuksköterskor påverkar patientsäkerheten vid skift- och övertidsarbete. Metod: Metoden är litteraturstudie med tio kvalitetsgranskade vetenskapliga artiklar som utgår från kvantitativa studier.

Integrering av gamification i reklam : utmaningar, möjligheter och problem

In this study, we have explored a new area called ?gamification? ? a word and concept that was first introduced on the Internet autumn 2010. Gamification concerns integrating game design, with emphasis on game mechanics and game dynamics, into non-gaming contexts ? such as marketing. At its basic definition, it concerns the process of transforming all kinds of activities into games.

Energieffektiva värmesystem : Lösningen till att nå energimålen i byggbranschen?

Sweden has an environmental goal to achieve until the year 2020. To achieve this goal the construction business has to take an initiative to use the modern techniques that are available to lower the energy consumption I buildings. There?s also a debate going on today regarding the energy demands set by the Swedish government through Boverket, some communities throughout Sweden thinks that the demands are to low and have therefore set up own demands regarding energy in buildings.The possibility to construct energy-saving buildings is today very great, with energy-efficient heating-systems and dense climate envelope. The interest to raise energy-efficient buildings have also increased as a consequence that the population have become more aware about their impact on the environment.

En för alla, alla för en : Vad är sammanhållning och vilken innebörd har begreppet sammanhållning för SISU`s idrottskonsulenter.

The purpose of this study was to find out how SISU reason about cohesion with respect to its own operations, as sports consultants.There is no previous research on how sports consultants using cohesion as a pedagogical tool. However, there is research on cohesion linked to sport. Earlier research sees cohesion as a multidimensional phenomenon. This means that multiple factors determine the experience of cohesion. Such factors include how how-knit the team or group are, individual and joint objectives and that the individuals share common experiences.

Action Naming Test (ANT) - Reanalys och normering av insamlade data i en population svenska vuxna

Många studier har påvisat en skillnad mellan förmågan att benämna verb respektive substantiv hos patienter med hjärnskada samt hos kontrollgrupper (Caramazza & Hills, 1991; Mätzig, Druks, Masterson &Vigliocco, 2009; Szekely et al., 2005). Samtidigt bedöms aktivitetsord utifrån vissa studier vara mer krävande att tolka, vilket kan vara en bidragande orsak till skillnader i benämningsförmåga (Liljeström et al., 2008; Mätzig et al., 2009).Action Naming Test (ANT) är ett verbbenämningstest utformat av Obler och Albert 1979 (Barth Ramsay, Nicholas, Au, Obler & Albert, 1999), vilket översattes till svenska och normerades av Lindahl och Oskarsson inom ramen för ett magisterarbete i logopedi (2011). I normeringen genererade vissa ord många felsvar och sågs som problematiska, och en reanalys av det insamlade materialet efterfrågades. Syftet med föreliggande studie är att genomföra en förnyad analys av insamlade data och ta fram en ny normering för ANT i en population svenska vuxna, efter exkludering av problematiska ord.I syfte att undersöka vilka ord som gav upphov till många felsvar och orsaker till detta, gjordes en ny genomgång av 120 tidigare insamlade testprotokoll, samt en felsvarsanalys baserad på Barth Ramsays och medarbetares utvecklade modell (1999). Efter genomgång av angivna svar, analys av felsvar och ordens användningsfrekvenser i svenska språket, exkluderades tolv ord.  Jämförelse av resultat mellan tre åldersgrupper (20-30år, 31-65år, 66-83år), två utbildningsnivåer (?12 år, ?13 år) och kön gjordes både före och efter borttagning av de tolvorden.

Kan gullstånds hålla stånd?- återinventering av Senecio paludosus i Kristianstad Vattenrike 2012

Botanist Kjell-Arne Olsson inventoried the plant fen ragwort Senecio paludosus 1983 in Scania andfound a big number of locations within Biosphere Reserve Kristianstad Vattenrike. In 2012, a reinventoryof the 1983 survey was carried out to study whether there has been any change in the fenragwort population in Kristianstad Vattenrike since the last inventory. The results show that therehas been no overall change in the number of fen ragwort in Kristianstad Vattenrike, on certainpremises they have increased in number while in others they have fallen. However, the inventoryshows that almost half of the locations with fen ragwort have disappeared during the same period.The main reason for this is that fen ragwort did not manage to competitive with other vegetation,taking in consideration this has been smaller premises with young plants. In addition to competitionother factors such as prolonged high water, grazing and caterpillars from Tyria jacobaeaecontributed to the decrease.

Attityder till återintroduktion av visent i Sverige

The European bison is a species which is no longer present in the wild fauna of Sweden. Reintroduction has been proposed in several different forums. Reintroduction is an attempt to reestablish a viable population of a species in an area to which it is native. To make such an operation successful in the long run it is essential to know the attitudes of the stakeholders involved. This study has sensed the attitudes towards reintroduction of European bison to Sweden.

Effektiv marknadsföring genom segmentering : i ett litet kommunalt bostadsföretag i glesbygd

It is important to Ockelbogårdar to have knowledge about different needs by the segments on a market, while they can bring a product into line with consumer needs by marketing. To survey the needs of consumers, demographic segmentation could be in use. It is about to survey the most importent factors or advantages the consumers have in their living environment.The purpose of the essay is to investigate how Ockelbogårdar could make their marketing better against several target groups, in the existing building population, by distribute the consumers into segments. On the basis of the investigation and the segments that will introduces, Ockelbogårdar can offer the consumer a living which fits the indivdual consumer.A poll have been done by the conusmers of Ockelbogårdar. The poll have been delivered by post and a quantity data about the needs of the consumer have been evaluated.

Med andras ögon : En intervjustudie av åsikter och värderingar om effekter och produkter av det svenska jordbruket

The majority of the Swedish population were self-provided within agriculture a hundred years ago. Times do change and today the situation is the other way around - most of us live within city boundaries and only few work with farming and related agricultural businesses. One thing that has not changed though, is the need of supplies from Swedish agriculture.What do we think of those products? Are we even aware of the connection between us and agriculture? The Federation of Swedish Farmers, LRF (Lantbrukarnas riksförbund), started their project to strengthen the link between consumers and producers in 2008.This paper is part of the project and its aim is to investigate consumers' views and values upon the effects and products from Swedish agriculture.Opinions and values have been studied through interviews influenced by phenomenology. The results show that the informants in general had a positive approach and thinking concerning the products and effects from Swedish agriculture.

Läroboken svart på vitt : En diskursanalys av åtta samtida geografiböcker

ABSTRACTA Qualitative Discursive Analysis of Eight Contemporary Geography BooksTeacher Training with an Intercultural Profile 2006Author: Susanne LjunglöfTutor: Jan-Eric MattsonThe aim of this paper is to describe which discourses concerning the different continents problems, future and development that I can find in the descriptions of the continents in a number of contemporary geography books.The aim has been divided in four questions:- Which aspects of the continents problems are expressed in these geography books?- Which impressions concerning the continents development and future are expressed in these geography books?- Which conceptions about the population in the different continents are expressed in these geography books?- Which cultural reference creates these discourses?The method used for conducting this study is a text analytical method called general discourse analysis.My conclusions:- The different continents problems, development and future are described through entirely diverse discourses.- The reviewed geography books take their origin i a western perspective in their description of the different continents.- As a reader it is always important to be aware of the ethnocentric perspective that could be expressed.
