Om behovet av ett avrinningsområdesanpassat skogsbruk

The Swedish forest have about 100 000 km of watercourses and it?s an important structure in Swedish landscapes and catchments. In some of the watercourses lives spieces like the freshwater pearl mussel (Margaritifera margaritifera) and brown trout (Salmo trutta) which both are sensitive for inteference from the forestry. The new EU water framework directive has a goal that all surface water will have high or good ecological- and good chemical status at latest by the 22nd December of 2015. The study has been made in the catchment of Håltjärnsbäcken and it is from a national perspective one of the most valuable streams in Sweden and which also have been included in a LIFE-project. The catchment is situated within the Eco-park of Malingsbo-Kloten and managed by Sveaskog AB.

The major food trees of the Angola black-andwhitecolobus (Colobus angolensis palliatus)in Diani Forest, Kenya

The Angola black-and-white colobus (Colobus angolensis palliatus) is a subspecies of Colobus angolensis inhabiting fragmented forests in coastal Kenya and Tanzania. C. angolensis is regarded as Least Concern in the red list of IUCN because its populations are abundant. However, the populations of C. a.

Welfare impairment of lambs around weaning. Play and other behaviour indicative of affective state

The abrupt and early weaning of intensively kept lambs may have serious animal welfare implications, but relatively little is known about this. Weaning includes the breaking of the mother-young bond and abrupt replacement of milk by solid food, often coinciding with changes in the (social) environment. Altogether, these changes are likely to affect lamb welfare significantly. This study aimed to establish how strong and persistent lamb welfare is impaired following abrupt weaning by means of measuring behaviour parameters indicative of affective state. Also, we investigated the existence of a diurnal rhythm in play behaviour, which is considered an important indicator of positive affect and good welfare.

Konsten att lyckas med förankring

The purpose of this thesis work is to formulate a model with methods that describe key success factors to get understanding and awareness in organizational change projects. We have used a project within the township of Gothenburg as a case and connected to this single project the purpose is to identify key success factors to get understanding and awareness among employees within the township of Gothenburg. We hope that our result will be useful in other large organizational change projects. Theoretic basis for our study have been models and methods, while our purpose have been to construct a model with suitable methods for anchoring. Theories about coaching and process management are examples of methods to get understanding and awareness among employees in change projects.

Flygbildsanalys av trädskiktets status efter brand : en metodstudie

During the past years fire has been identified as an important factor for nature conservation in the forest landscape. To accurately quantify the size of a burnt area is obviously important, but also to quantify the degree of fire damage to the tree canopy. Such data are important for assessing the conservation value, and to support planning and management of the burned area in the future. I have examined how to estimate the status of tree crowns after fire from interpretation of aerial photographs. This is possible because fire changes the structure of tree crowns and this influences the colours in aerial photographs by spectral reflection. Included in the study are four areas, three of which burned in 2005 and one in 2006.

Lärares bedömning av bildämnet vid en lärarutbildning i Sydafrika : En minor Field study

Bedömning av estetiska ämnen har varit ifrågasatt gällande dess kvalité, rättvisa, funktion och hur det påverkar ämnet och individen. Studien syftar till att beskriva bedömning av det estetiska ämnet Visual Arts vid en lärarutbildning i Sydafrika presenterat ur ett lärarperspektiv. Forskningsfrågorna utgår från ämnesdidaktikens teori gällande Vad bedöms, Hur kommuniseras bedömningen och Varför görs bedömningen. Metoden som använts är ett två månaders fältarbete vid en bildlärarutbildning där jag följt tre lärare och deras arbete genom deltagande observation, samtal, intervjuer och insamling av vissa dokument.Det empiriska materialet har analyserat från de tre didaktiska frågorna. Resultatet visar att lärarna, som var utbildade konstnärer lade ned mycket tid och engagemang på bedömning.

Kan nutritionsbehandling bidra till läk-ning av trycksår bland äldre patienter?

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionTitle: Can nutritional support contribute to the healing of pressure ulcers in elderly patients?Author: Anton Kinnander, Sandra SmidelikSupervisor: Elisabet RothenbergExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 12-04-11Background The number of elderly patients with co-morbidity is increasing in the western world. It is therefore reasonable to predict increasing incidence and prevalence of pressure ulcers. One study, published 2009, found that as many as 59 % of geriatric patients within the Swedish health care system had developed pressure ulcers. Symptoms vary from mild erythema to severe deep tissue damage and development of pressure varies from hours to weeks.

Vindfällning, tillväxt och plantuppslag i en 13-årig granskärm i Medelpad :

The interest for alternative forest regeneration methods increased significantly during the 1990´s after 50 years dominance of the clear-cutting system (Holgén & Hånell 2000). One reason for this was that clear-cutting was being more and more questioned by different envi-ronmental organizations and because the forest sector for economical reasons wanted to find cheaper ways to regenerate forests. In the beginning of the 1990´s two shelterwood experi-ments were established in a joint effort by Svenska Cellulosa Aktiebolaget (SCA) and the Dept of Silviculture, Swedish University of Agricultural Sciences (SLU). The experiments include various forms of cutting and shelterwood densities and represent productive spruce forests in central and north Sweden (Roggsjön in the province of Medelpad and Skikkis-jöberg in the province of Västerbotten, respectively ). The experiment next to Roggsjön has been reported earlier in three MSc theses, and is also the focus of this thesis.

Klövviltets besöksfrekvens och bete i sydsvenska poppelplanteringar

Energy is an essential part of the society and for a sustainable future we need to use the energy resources in a sustainable way. The forest is Sweden?s most important resource for renewable energy and a higher production combined with shorter rotation periods (time from planting to clear cutting) can increase the access to energy. The tree genus poplar (Populus spp.) is interesting as energy resource as it has both high production and short rotation period. But browsing ungulates are a major threat to the establishment of poplar plants and therefore the poplar plantations need to be fenced in today. To use fences is expensive and time consuming; this makes it interesting to find more cost-effective solutions where there is no need to fence. The aim with this study was to look at the ungulates? occupation rate and browsing pressure in poplar plantations without fence.

Grupper vs. Individer : en kvantitativ studie om gruppers risktolerans i förhållande till individers

Beslut angående finansiella investeringar sker för den enskilde individen likaväl som i företag. Besluten följer den finansiella världens utveckling och blir därmed alltmer komplexa. Placeringar av monetära tillgångar med förväntan att generera inkomst eller värdestegring innebär en risk. Risknivån på investeringen beror på investeringsbeteendet hos beslutsfattaren som kan ge konsekvenser på den finansiella marknaden och kan så småningom leda till finanskriser om ett överdrivet behov av risk uppstår hos beslutsfattare.Genom att studera vad som påverkar risktolerans öppnas dörrar för att kunna förstå vad som ligger bakom vilken risk som väljs vid en finansiell investering. När förändring i risktolerans studeras tas hänsyn till vilka sorters beslutsfattare som finns på den finansiella marknaden.

Inverkan av ensilagets partikelstorlek på beteende och beteendestörningar hos mjölkraskvigor :

Modern milk production have come a long way when it comes to accommodating the nutritional and physiological needs of the animals, but unfortunately the behavioural and psychological needs of cows and heifers are often left unfulfilled. A long time for eating is beneficial for the digestion and also gives the cattle something to do and decreases the risks for developing abnormal behaviours. An important factor that influences eating- and ruminating time is the particle size of the roughage. The aim of the study was to find out if particle size influences the behaviour of dairy heifers, in particular with regard to eating behaviour and abnormal behaviours. The study was conducted at Uddetorp farm high school in Skara. Forty-two heifers of the breeds SR and SF were housed in 8 slatted floor pens.

Chemical and sensory analyses of juice, cider and vinegar produced from different apple cultivars

The interest for locally produced food is increasing due to consumer concern about the environment, distrust of industrial foods and a demand for high quality products. Apple is the predominant fruit crop in Sweden, and by processing apples into cider and vinegar, these products could significantly contribute to the development of the market of local foods.In this study different yeast types and different bacterial cultures were evaluated for their suitability in cider and vinegar production from cloudy apple juice. Ten apple cultivars (Aroma, Baldwin, Belle de Boskoop, Bramley, Cortland, Gravensteiner, Ingrid-Marie, Jonathan, Rubinola and Spartan) were also evaluated for their suitability for production of juice, cider and vinegar. Chemical analyses including total soluble solids, titratable acidity and total phenols were performed on the products along with sensorial evaluation by taste panels.The yeast strains were shown to have an effect on fermentation rate and the resulting content of total phenols in ciders fermented from cloudy apple juice. Dry commercial starter strains gave a higher appreciated cider compared to cider that was spontaneously fermented, and the ale yeast Safale S-04 was concluded to be the most suited for fermentation of cloudy apple juice.For vinegar production, the bacterial culture had an effect on TSS, but not on any other chemical or taste characteristics.

Nytt ventilationssystem till djurstallar :

There is two dairy farms in Sweden with ability to be opened on both long sides, one outside Hjo and the other one, Brandstadholm, north of Sjöbo. When there is no measures and results or not enough literature about natural ventilation and especially on this kind of air inlet, makes my tests very interesting not only on Alnarp, but among other companies. I would like to find out if there is any air movements direct on the cows, how high/low temperature, air humidity, light intensity and noise standard inside the barn. Does Brandstadholm fulfil the rules and regulations when it comes to climate inside the barn? Could this system become the new dairy barn instead of the conventional barns in Sweden? I am going to focus on the animals environment, after all they are the one who is going to spend the most of the time in the barn. I used five electrical loggers distributed inside the barn to measure the temperature and one of the loggers measured the air humidity, every 15th minute. One logger were placed on the outside which measured both temperature and air humidity.

Vilka faktorer påverkar ett mjölkföretags tillväxt? : en jämförelse mellan Sverige och Danmark

Dairy farms have during a long time been under pressure and this situation was aggravated during the spring and summer of 2009, when profitability declined to historically low levels. Lower milk price and relatively high input prices have caused Swedish dairy farms great liquidity concerns and profitability problems. For a long time, Denmark has been identified as a leading country for the agrarian development with a leading structural rationalization and willingness to grow. In 2009, it was shown that the Danish agriculture, which is generally more leveraged, has difficulties in maintaining profitability and when market price of land started to fall, the proportion of technically insolvent agricultural enterprises rose dramatically. In light of this prevailing situation, this study highlights differences between Denmark and Sweden with the hope to learn from each other.
