Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell

The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.

Kalkylering i flygbranschen: En fallstudie av ett flygbolag

The purpose of this thesis is to analyse and propose improvements to the cost accounting system in use at an airline operating on the Swedish market. The choice of study object is based on the airline?s desire to have its cost accounting system evaluated. During the analysis we have identified a number of points where the current cost accounting system does not correspond to its intended purpose. These points include significant groups of costs not being considered in the current system, potential over capacity is not visible and logic connections between distribution keys and the use of resources are sometimes lacking.

Eget företagande - en permanent verksamhet inom Sfi? : En projektanalys av "Eget företagande - egen försörjning"

This is a study of an experimental project called ?Eget företagande ? egen försörjning?.

The study is based on interviews with participants from the projects management team and the interviews has been analysed with methodological inspiration from Jonas Söderlunds project competence model. The focus lies in the participant?s perception of the project work and their thoughts about the permanent activity of self-employment in the future.

Ungdomars deltagande vid alternativa idrottsinsatser : Vilka deltar och varför?

This study's main objective was to identify adolescents participation in alternative sport activities and which kind of physical activity that was preferred by adolescents who didn't had any earlier experience of sport clubs. The study combined interviews and surveys with the purpose to get both adolescents and sport leaders perspective. A total of five interviews were performed and fifty-four surveys was collected. The results showed that adolescents already physical active were those who participated in alternative sport activities. Who participate in alternative sport activities can depend on habitus, comprehended capital forms and in which social field the sport activities exists..

Evaluation of Lactobacillus reuteri DSM17938 as starter in cheese production

The probiotic bacteria Lactobacillus reuteri DSM17938 was evaluated as a starter culture in cheese production, with the intention to produce a new interesting product within the functional food market. Growth and acidification rate in milk subjected to different heat treatments, as well as supplementation with growth promoting factors or support cultures was measured during controlled fermentations. The results showed that the weak proteolytic activity of L. reuteri could be compensated for by supplementation with 1% casamino acids or 5% MRS broth. Furthermore, a decrease in growth and acidification rate could be seen when using yoghurt culture or Lactobacillus delbrueckii as adjunct cultures.

Elasticitetsmodulen i en kalkstabiliserad vägterrass : en fältstudie

Stabilization of subgrade is an internationally common technique to improve the characteristics of a soft soil. Improving the stiffness and bearing capacity of the subgrade enables the pavement to be designed with reduced depths of subbase and basecourse aggregates. This makes the stabilization technique both economically and environmentally interesting. Both natural and stabilized soils have high inherent property variability that should be considered when the characteristic value is derived. By analyzing the spatial variability in stabilized and natural subgrades it is possible get the parameters needed for reliability?based modeling of soil properties.

Biblioteket går till sjöss: Kultur-, informations- och fritidsutbudet för ombordanställda i svenskflaggade handelsfartyg.

This paper deals with how seamen onboard merchant ships flying the Swedish flag apprehendthe culture, information and leisure possibilities that offer them by the Swedish GovernrnentSeamen's Service, HKF.The objective with this work is two folded: first of all suggest some actions to be taken inorder to improve the situation for seamen, based on the results from interviews with crewsonboard three merchant ships.Secondly, draw the attention to HKF's activity in general and to the activity of the SwedishSeamen's Library in particular, for people working within libraries.The result of this examination shows that people onboard really regards the service carriedout by HKF as very good in general, but there are some activities which hopefully can beimproved. However, perhaps the most important role can be played by the shipping companies,based on the wishes that came about from the seamen. These conclusions and discussion aredealt within chapter 8..

Energianvändning för markkonstruktioner förlagda med ytvärme : En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören

The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.

Att bli någon : Unga kvinnors identitetsskapande via Bloggar

The aim of the study was to through a qualitative method with two focus groups investigate how young women percieve that their identity creation is influenced by them reading celebrities Blogs and in that case, whether this type of Internet activity affect their autobiographical memory, the foundation for personal identity. Since the main task of the autobiographical memory is to give the ego and its social mode a foundation by sharing memories with others, the Internet activity should be seen as an important factor for the identity formation of young people. Today, the young spend equally mauch time being connected to various media as they do socializing with family and friends. The results indicate that young women view the world and lifestyle that known Bloggers expose intheir Blogs as a kind of ideal. The young women got an aha reaction when they realized that what the Bloggers expose is not always equal to the real life..

Integrerat växtskydd i svensk jordgubbsodling : attityder bland odlarna till genomförande av det nya direktivet

This study was conducted at VikingGenetics' bull breeding station in Falkenberg, Sweden. The bulls waiting for the results of their progeny testing at this station are either kept in group housing or individual housing. Since both of these housing systems have advantages and disadvantages, it was in the interest of VikingGenetics to know which of these housing systems is the best. The aim of this study was to investigate the welfare of the bulls in these two housing systems through behavioural observations and the use of activity monitors. In the preparations for the study 16 bulls, 8 in each housing system, were chosen.

GIS och statistik vid dräneringsområdesvis kväveläckagebeskrivning i Halland

The last decades have shown increased nitrogen leeching from soil to water recipients. This is inSweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and thedeclining extent of wetlands. The accumulated amount of nitrogen in water doesn?t only make itunsuitable for use by humans and cattle, but also decreases the biological diversity as well as negativelyaffect tourism and fish industry. In the most severe cases shallow maritime grounds can be completelydepleted of oxygen due to decomposition of the increased amount algae and plankton growth.This study have the aim to describe and quantify the nitrogen leeching from the Genevad drainagebasin, located in southern Halland, Sweden.

Värdet av skapande i förskolan : En studie om pedagogers förhållande till skapande verksamhet i Stockholm och i Tornedalen

The purpose of this study was to investigate how preschool pedagogues in Stockholm and in Tornedalen speak about and relate to creative activities. By qualitative interviews in two geographically distant areas, one minority culture and one majority culture, I have collected information from six pedagogues, three in each area. Values in, and the significance of culture in creative activities have been the main focus. From this study I conclude that all pedagogues agreed upon the creative activity having an extensive role in the preschool work. The role of the individual pedagogue within the creative activity is multiple and dependent on where, when and how the activity is carried out.

Mission och mänskliga rättigheter : Svenska Missionsförbundets missionsverksamhet i Kongo-Brazzaville 1909-1961 ur ett ma?nniskora?ttsperspektiv

This paper?s purpose is to examine a Swedish missionary activity from a human rights perspective. As a scope I have chosen the Swedish evangelical mission to Congo-Brazzaville, from its establishment in 1909 to the congolese church's self-determination in 1961. I consider certain elements of the missionary activity that affect human rights, to discover wether the activity was in order with modern day human rights standards or not. During these years, Congo was part of the French colony Equatorial Africa, so the missionaries? part in the colonial discourse is taken into consideration.
