Gröna generationsskiften : Särskilt om samäganderätt och mjuka frågor

Within the near future Sweden will be facing a large number of successions of ownership  within the agriculture and forestry sector, which is why it is important to acknowledge the question of alternatives for transfer of ownership. The purpose of this thesis is therefore to analyze the existing law as well as the various options for how to transfer the ownership concerning succession of ownership within family-owned agriculture and forestry businesses. This thesis pays particular attention to the complexity of problems that refer to joint ownerships and the great importance of the emotional questions that arise when a succession of ownership is being implemented.A succession of ownership can be planned as well as unplanned. When implemented through inheritance the transfer to the younger generation is unplanned. There are several effects of an unplanned succession of ownership and these effects can be harmful for the company as well as the family.

DGPS användning på tröskor och dess olika funktioner :

With the days DGPS-technology can a position of 5 centimetres decides. With this exactly position is the technology very interesting for the agriculture. I think this technology can come more and more in the future. You can also move the fact and information further to the spreader, sprayer and seeders. If the combine is equipped with harvest accounting, can you with help of the system make harvest maps.

Behandlingsvåtmarkers reningseffekt på aktiva läkemedelssubstanser under vinterförhållanden : En studie av fyra svenska våtmarker för avloppsrening

Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.

Karaktärisering av avfallsbränslen

All products will eventually end up as waste, which in a sustainable society has to be handled in an efficient and environment friendly way. This report focuses on waste fractions meant for combustion, often difficult to characterize. However, more homogeneous fractions that are treated biologically are also discussed.The study concerns the region of Borås, Sweden, where the waste plant Sobacken has provided a good starting point. On this site, fuel to the Energy-from-Waste plant of Borås Energi is prepared and the biological waste is treated through anaerobic digestion.One important part of the study has been to collect experience-based knowledge from the technical staff at Sobacken and Borås Energi. This information was compiled into an overview of wanted and unwanted fractions to the preparation plant and the boilers respectively.

Bibliotekariestudenter och söksträngsexpansion: Ett experiment om manuell söksträngsexpansion

The focus of the thesis is an information search technique called manual query expansion, which aims to improve the retrieval per-formance in a search system by adding terms to the search query. The study looks at the query expansions done by LIS students, and the eventual beneficial effects by using a search help during the search process. The empirical data have been collected thro-ugh an experiment, with an experiment group as well as a control group. The conclusion is that the students need more education in query expansion in order to be able to use it correctly. There are significant differences between the groups in several aspects, for example in the use of search terms, parentheses, and truncation.

Kommasköldlusen Lepidosaphes ulmi (Linnaeus) i svensk äppelodling : livscykel och naturliga fiender

Lepidosaphes ulmi ? kommasköldlusen har dykt upp som skadegörare i svenska äppelodlingar de senaste åren. Svenska äppelodlare har efterfrågat mer information kring kommasköldlusen och dess naturliga fiender, och därför gjordes denna litteraturstudie. Kommasköldlusen är en pansarsköldlus med ett hårt skyddande skal. Även äggen läggs under skalet och de är därför svåra att bekämpa.

Galoppträning och körning med två travare

The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.

U.M.B: - en digitalt skapad bildserie

Denna workbook behandlar produktion, resultat och analys av en serie digitalt producerade bilder, presenterade i form av en tryckt bok. Dessa bilder gjordes genom att frilägga och behandla en mängd bilder i Adobe Photoshop, för att sedan länka och montera dessa i Adobe After Effects. Efter detta, applicera ett antal effekter såväl som en simulering av en kamera som fotar kompositionen, för att senare lämna över bilden för efterbehandling i Photoshop. Syftet med detta var att undersöka hur dessa två program kan komplettera varandra vid skapande av digitala stillbilder.Den slutgiltiga artefakten blev en spiralbunden bok med åtta uppslag, innehållande bildseriens samtliga fem bilder..

Säkerhetsbrytare för Gräsklippare

This thesis describes teh solution of two problems regarding safety on powered lawnmowers; protectning the users from injury when using the lawnmower in slopes, and when cleaning the cutting blade.The task was carried out through initial studies on a representative lawnmower. A generation of ideas followed with an evaluation to select the best solution. The winning concept was further developed to reach acceptable performance. The word resulted in a functioning prototype utilising an original way of detecting inclinations without incorrect signals. It c an serve as a platform for further development into a product.The work gives insightful experience of solving real-world problems, and especially to deal with situations where several variables and their effects are unknownPlease note that several parts of the work are confidential, and have therefore been removed from the thesis..

Vaselin som kontroll vid försök med 1 % väteperoxidkräm i färska hudsår på häst

Wounds on horses are common and sometimes difficult to treat. The wounds are often big and could be discovered too late for primary sutures, which have to be applied within 8 hours from time of accident, before bacteria has been able to infiltrate the surrounding tissue. The healing is often complicated by delayed healing and wound infection with consequences like phlegmone, fistulation and proud flesh formation.To avoid these consequences, the traditional practice has been to administer systemic antibiotics alone, systemic antibiotics in combination with topical antibiotics or topical antibiotics alone. Because few antibiotics can be used in horses, is it important to household with the few substances that are available. In veterinary medicine today, the increasing resistance amongst pathogenic microbes such as MRSA presents a growing problem.

Translationsnoggrannhet i läsningen mellan tRNA och mRNA : En analys av variationen i den maximala diskrimineringen d i initialselektion

The purpose of this thesis is to analyze the variation in the maximal discrimination of the interaction between cognate and a non-cognate codon and anti-codon (also called the d-value). The variation was analyzed with a multiple regression model with the d-value as the dependent variable and with the codon position and the different mRNA and tRNA bases as independent variables. The result of the analysis not only confirmed earlier studies that the maximal accuracy was highest in the second codon position and lowest in the third codon position but we also found significant relationships and interaction effects..

Blästring av trä : Ett materialbibliotek av blästrade och ytbehandladeträytor

In my thesis I have sand blasted different type of woods - ring-porous and diffuseporous deciduous tree species and conifers - to show different results depending on the species, the direction of the grain and the effects of surface treatment of a blasted surface.The results of my tests were sometimes unexpected, such as that the sand from blasting almost completely disappeared, that all wood surfaces after blasting exhibited a much lighter or paler surface than before and that the diffuse-porous tree species showed differences in hardness between the beginning and end of annual rings.By creating a library of different kinds of wood and sandblasted surface treatment, I have created a reference bank that I will be able to use me in the manufacturing of interiors, furniture and other objects..

?Jag är typ bara en sån som gillar att läsa? : En studie av pojkars läsvärldar på en högstadieskola i södra Stockholm

Every now and then, in media research studies and in various newspaper articles, schoolboys´ issues reading habits are discussed. Much of what is written concerns boys decreasing marks in the field of literature, in the Swedish language and also their negative attitude towards reading books. Some scholars claim that boys do not read because they consider reading books as a women´s duty. Other people believe that underlying causes for boys negative attitude towards reading is biological, that it´s genetic and consequently physical, and that male and female brains are functionally different. Another theory of today is that boys actually reads, but not that kind of texts and literature that they are exposed to in school.Based on a selection of these opinions and theories, and my own experience and interest for questions concerning school and gender, the aim of this studie was to examine boys worlds of reading.

Bullrets omfattning och inverkan på sjukhusmiljö

Syftet med litteraturstudien var att undersöka hur buller påverkar sjukhusmiljön med hänseende på vårdpersonal och patienter. Studiens avsikt omfattar även en undersökning av vårdpersonalens och patienters eventuella olika uppfattningar angående buller. Effekterna av buller och dess omfattning inom vårdavdelningsmiljön har också undersökts. Resultatet av studien visar på att bullermiljön på sjukhus överskrider de riktlinjer för buller som WHO fastslagit. Vidare visar studien på indikationer på att brittiska sjuksköterskors kunskap angående fenomenet buller är bristfällig.

PÅVERKAS DEN KOMMUNALA SKATTESATSEN AV POLITISKTSTYRE? : En strukturell analys av faktorer som avgör skatten i svenska kommuner

The aim of this report was to investigate which factors determine municipal taxes in Sweden.The aim was also to find out whether and how the forms of political rule are significant covariates. A multiple regression analysis was performed using data from 289 municipalities. The analysis resulted in five dierent models, of which a model based on municipal grouping was found to be most satisfactory. In all of the models, there are effects from the form of political rule. The results indicate that socialist municipalities have higher tax rates than non-socialist.
