Analys av fiskerättsförhållandena i Stockholms skärgård i relation till känsliga områden samt fysisk störning
This work is a GIS study of fishing rights distribution between different categories of ownersand properties in the Stockholm Archipelago. The purpose was to create basic data used toestablish fishing laws and restrictions within the Stockholm County.Stockholm?s archipelago consists of a unique environment and is the natural life andreproduction environment for ? of Sweden?s reproducing fish species. The increasingpressure from fishing, tourism and weekend population increases the need for an efficientfishing administration to prevent impoverishment and to ensure the biological diversity inSwedish fishing waters. There is an increasing need to review fishing administrationmethodologies, as well as studying the categories of ownership and properties located insensitive areas and areas influenced by physical disturbances in order to establish effectivelaws and restrictions.The Swedish fishing rights for an area are currently not connected to the ownership of theproperty to which it belongs.
Betesdrift vid automatisk mjölkning i ekologisk produktion :
An automatic milking (AM) system should be combined with some form of controlled cow traffic to minimize the time spend on fetching cows to milking and to increase the milking frequency. By restricting the hours spent on pasture per day you optimise the AM system use during pasture period. A reason for this is becuase cows do not return to the stable for milking during night which cause that the milking unit stands empty those hours. In organic production it is required that the cows should be able to graze a certain amount of daily dry matter (DM) intake on the pasture. In the county of Dalarna where the farm is located the yield of the pasture is about 3000 kg DM per grazing season and hectar.This means that the pasture area should be 14,25 hectare to 57 milking cows.
Tungmetaller i metabolismen hos värphöns och slaktkycklingar
Mussel meal is a potential source of protein, with a good composition of amino acids, for laying hens and broiler chickens, and may replace the use of fish meal in organic poultry production. Lead and cadmium are heavy metals which occur in the environment and can be accumulated in mussels. When poultry are exposed to heavy metals, the metals are absorbed in the small intestine and distributed in the body in the form of ions, complexes or bound to proteins. In poultry, lead accumulates in bone tissue, liver and kidneys, while cadmium accumulates in liver and kidneys. Generally very low concentrations of these heavy metals occur in muscles of broilers which have been exposed to feed contaminated with cadmium or lead.
Evaluating a corporate strategy : a case study of Länsförsäkringar
The Swedish agricultural sector is currently undergoing a substantial structural change. The number of farm enterprises is continuously decreasing and the average farm size is increasing. In combination with increasing number of competitors in the insurance market, the competitive rivalry within this market has increased significantly. With this knowledge in mind, Länsförsäkringar Uppsala initiated this study, which aims to provide an understanding of customer?s view on customer value, related to agricultural insurance and financing.
Betydelsen av återskapade våtmarkers ålder, area och fiskförekomst för simfåglar : En biologistudie ur ett lärarperspektiv
Återskapade våtmarker är av stor vikt för den biologiska mångfalden och särskilt viktiga för hotade simfåglar. För att öka kunskapen kring hur faktorer som våtmarkers area, ålder och fiskförekomst påverkar simfåglar i återskapade våtmarker studerades fyra våtmarker i Tinnerö naturreservat, Linköpings kommun. Av speciellt intresse var svarthakedoppingen (Podiceps auritus). Antalet svarthakedoppingar i de studerade våtmarkerna hade en positiv utveckling under våtmarkernas första år. Dock minskade antalet svarthakedoppingar i området mellan år 2009 och 2011.
Mineralämnen i fullfoder : studier på 20 mjölkkogårdar i Halland
In 2003 the recommended phosphorus allowance for dairy cows in Sweden was lowered approximately 10 %. For a cow at a production level of 35 kg ECM it decreased from 0,40 to 0,36 % of dry matter. To investigate if the decrease has been implemented at farm level, analysis of following minerals; P, Ca, Mg, K, Na, S, Se, Cu, Mn and Zn was performed on the TMR at 20 farms in Sweden in the summer of 2004. The purpose was to describe the actual allowance of different minerals as compared to the new recommendations. One hypothesis was that the decrease in recommended allowance of phosphorus would lead to the need of new mineral feeds on the market.
Spenarnas kondition i automatiska mjölkningssystem : en studie av två spensprayer
Two post milkning teat dips (PMTD´s) were compared in an automatic milking system at Kungsängen Research Farm, owned by SLU (Swedish University of Agriculture) in Uppsala. In the experiment an evaluation system was used where teat condition regarding skin and teat ends was graded according to a scale where 1 was the best score and 5 the worst. The evaluation period was almost six months in total devided into four minor experimental periods. The technician scoring the teats did not know which PMTD that was currently used. Statistical analysis showed a significant difference between the two PMTD´s regarding teat skin condition, but not regarding teat ends.
Aktivitet, läggnings- och resningsbeteenden, tillväxt samt renlighet hos kvigor i liggbås respektive djupströbäddsbox :
The aim of this study was to compare activity, lying down and getting up behaviour, weight gain and cleanliness in heifers in cubicles versus on deep-litter.
The study was conducted from autumn of 2005 until autumn of 2006 in a commercial organic dairy herd with 340 cows. In 2005 the farm rebuilt half of the young stock accommodation from deep-litter pens to cubicles. The experiment used 150 heifers of the breeds Swedish Red, Swedish Holstein and crossbreeds between these, all born on the farm. The animals were divided into three blocks based on breed and within each block they were sorted after increasing age. The youngest heifer in each block was randomly allocated to one of two groups, cubicle or deep-litter pen.
Lantbruksföretagets tillväxtstrategi och finansiella sökbeteende : en empirisk studie av sex lantbruksföretag med tillväxtambitioner
The structural rationalization of the agricultural sector in Sweden has led to many expansive, professional companies orientated towards growth. The agricultural sector is a very capital-intense sector and is characterized by the need for large sums of capital in form of buildings, inventory and arable land. The capital need is especially large for companies who have an ambition of growth and development of the company in the near future.
The study is built upon six cases that all can be categorized as large agricultural farms with a turnover exceeding 20 million Swedish crowns. The companies are located in the middle and in the south of Sweden and are in the sector of primary production with focus on dairy-, pork-, egg-, chicken-, beef-, vegetables- and grain production as well as in the business of refining milk towards consumers.
The study aims to identify the motives and driving forces that lies behind the growth of a farm-based company. The agricultural companies' motive for growth is studied based on which factors that influence the ambition to grow and to what extent these factors accord to the picture given by earlier research of small companies outside the agricultural sector.
Flottledsåterställning i norra Sverige: : effekter på habitatkvalitet och populationstätheter av juvenil öringar (Salmo trutta L.)
In an effort to evaluate the effects of restorations of float ways on population density of stream dwelling fish in relation to the changes in habitat, I studied the physical habitat restored and channalized sites and their population density of brown trout (Salmo trutta L.) in three streams in the municipality of Sorsele.
The differences between the channalized and the restored sites where most noticeable regarding substrate which where generally coarser in the restored sites. The analyses showed that the proportion of habitat that where suitable to the age class 0+ where significantly lower in the restored sites compared to the channalized sites. Regarding age class ?2+, no statistical differences in habitat quality were found.
Lean i den fysiska planeringsprocessen : ?It?s not about finding the big fish, but fishing all the time?
Den svenska planprocessens effektivitet är ett problematiskt och omdiskuterat ämne. Uppsatsen behandlar effektivisering av den fysiska planeringsprocessen med leanteoretiska begrepp som utgångspunkt. På senare tid har flera alternativa lösningar för effektivisering uppkommit. En av dessa lösningar är lean, en verksamhetsstrategi med ursprung från Toyotas produktionsfilosofi. Uppsatsen utgår ifrån en kvalitativ forskningsmetod med målet att genom intervjuer, offentliga rapporter och litteratur granska den svenska planeringsprocessen och fenomenet lean inom fysisk planering.
"A Queer Fish" : En Queerläsning av John Galsworthys The Forsyte Saga.
This paper aims to examine the heteronormativity that is present in John Galsworthy?s The Forsyte Saga. This is achieved by performing a queer reading of the text with the help of Swedish Queer theorists Fanny Ambjörnsson and Tiina Rosenberg. I study the norm and how it is enforced by law, society and family. To get a complete image of the heteronormativity I also need to analyze the gender presented in the saga.
Örter - en nisch? :
A tight economy and a keen competition force the Swedish agricultur to do a structural rationalization. The quantity of farmers is less but the units are growing. How to make money I think some kind of niche is necessary. In my examwork I have locked how to farm herbaceous plant and the marking of herb to feedstuff for horses.
Today health food and alternative medicine are accepted to use and there is an increase in demand.
The Swedish market for herbaceous plants to horses is small and the products are mostly imported. But there is a group of consumers who is willing to pay a higer price for Swedish cultivated herbs.
The only way to find out which herbaceous plants I could cultivate is to make a test cultivate.
I think that the market for herbaceous plants is growing.
Avveckla eller utveckla mjölkproduktion : vilka faktorer påverkar beslutet?
The decrease in the number of dairy farms in Sweden has been ongoing for a longer period of time. But the fact is that this has previously not had any big effects on total amount of milk produced in Sweden. The main reason is that the remaining dairy farms get larger. However, during the past year, there has been a decrease in the total amount of produced milk, because the decrease is faster than the increase within the farms that are left. During the same period of time the supply of milk on the global market also has decreased.
In spite of the fact that the global supply have decreased and the fact that the milk price increases, there are dairy farmers in Sweden who chose to exit the market.
Chromatin functions : the DNA repair connection
The aim of this master thesis was to examine a possible connection between chromatin functions and the DNA damage repair system, with the imprinted IGF2/H19 locus as a bait. Interactions can occur within and between chromosomes and it has been shown that H19 ICR on both alleles can communicate with alleles on other chromosomes. The methylation-sensitive insulator protein CTCF is bound on the maternal H19 ICR and acts as an insulator by blocking the IGF2 promoter to access its enhancers. This is possible by formation of loop structures by CTCF that enables intra and inter-chromosomal interactions. CTCF is poly(ADP-ribosyl)ated by PARP-1 when it is bound to H19 ICR.
