Hållbar design för gravplatser

A well-planned grave with a sustainable selection of plants facilitates easy maintenance for both staff and the holder of the right of burial. It also helps reduce the negative impact on the environment.As in many other areas, the environment is high on the agenda within the cemetery administration. One of the major concerns is the impact of the choice of plants for the grave. Within the industry there is a great motivation and willingness to adapt to a sustainable work mode and this has spawned a number of project works. In autumn 2009 the partnership project, ?Environmental aspects of planning and maintaining graves?, was started in Movium (at The Swedish University of Agricultural Sciences).

Tame animals in the wilderness : livestock grazing around summer farms in Jämtland, boreal Sweden 1800-2011

The forest and mire landscape surrounding the north Swedish villages have been of fundamental importance through time for the farmers. In the Scandinavian summer farm system the forest and mire pasture was used to its full potential. The system consisted of smaller summer farms some kilometres from the main farm in the village, and were the livestock grazed in the forest around the summer farm. The livestock affect their environment, and grazed forests generally contain a higher biodiversity than an ungrazed forest. The overall aim of this thesis is to understand the impact of livestock grazing on a northern forest ecosystem over a long time period.

Tidsåtgång i mjölkproduktion under betessäsong : inflytande av besättningsstorlek, samt mekaniserings- och automatiseringsgrad

Time studies in dairy production are an essential tool when deciding about level of mechanisation and automatisation both in investment situation and improving efficiency in existing operations. In previous investigations such studies have been carried out during normal barn conditions during winter. Since there is a compulsory to have dairy cows grazing 3 to 5 months during summer time in Sweden time studies during this season is important to have a full picture of needed working time. During grazing season time studies was carried out at 14 dairy farms representing herd sizes from 66 to 450 dairy cows of which 6 farms with AMS. 8 farms were the same as studied during winter season.

How Maasai settlements affect the grazing habits of the Common Hippopotamus (Hippopotamus amphibius) in the Maasai Mara National Reserve, Kenya

With a growing human population as well as a changing lifestyle, the conflict of wildlife and humans is intensifying. In Kenya, Maasais and their livestock have for a long time coexisted with wildlife, but an adjustment to privately own land and cultivation might rapidly change the terms for this coexistence. To understand how the Maasais and their livestock affect the wildlife in the Maasai Mara National Reserve and the surrounding area, this study was undertaken. The purpose of this thesis is to examine how hippos are concerned..

Internetbaserad rekrytering: mål, möjligheter och praktiker : En fallstudie av urvalet vid rekryteringen av sommarvikarier i Luleå kommun

The purpose of this study is to examine web-based recruitment to short term summer jobs at the SocialServices Department in Luleå municipality in Sweden. Recruitment goals, selection options on therecruitment homepage Offentliga Jobb and recruitment practices were analysed in order to reach a deeperunderstanding of the interactions between these three levels in the selection process. Pre-selection throughOffentliga Jobb was a special concern of the study. Different consciousness levels in the selection process areemphasised according to Anthony Giddens' structuration theory. Ten recruiters from different parts of thedepartment were interviewed.

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.

En jämförelse mellan får- och nötkreatursbetade hagmarker med avseende på populationsstorlek samt artsammansättning hos dagfjärilar och örter

Many of Europe?s day-living butterflies have shown decreasing populations during the last decades and many species are threatened. Many butterflies are dependent on managed semi-natural grasslands because of their richness in nectar sources and host plants for the butterfly larva. Swedish pastures are mostly managed through grazing. The number of cattle in Sweden have been decreasing while the number of sheep in the country increased by 30%.

Genomisk selektion inom köttraser

Genomic selection (GS) is used for selection of breeding animals of dairy cattle. GS is though not as extensively used within the beef industry. One reason for that is the low accuracy (rTI) of the breeding value that is of great importance for the final genetic gain. Causes to the low accuracy are high effective population size, a small reference population and a genetically differentiated population. There is however a market for genomic selection with High Density (HD) tests for beef cattle.

E-böcker på högskole- och universitetsbibliotek ? En studie kring det digitala förvärvet

This study aims to find out how the selection and acquisitions of ebooks made by university libraries is affected by vendors terms of sale. The empirical data is based on interviews with libraries working with selection and acquisition of ebooks. The interviews points out, according to Evans? model of collection development, that the collection development doesn´t work the same way with printed and electronic books. The study also finds out that the complexity of the ebook marketplace implies the application of new method of ebook selection, by libraries..

Förslag till skötselplan för Uppsala högar och Tunåsen : ett exempel på medbestämmande planering

This Master thesis is made at the request of the local municipality of Uppsala in Sweden. The purpose of this work is to create a guiding management plan. Recreation, conservation of the cultivated landscape and the historical environment, conservation biology and the aim of the landowners are all considerd. The area is almost 34 hectares and located north of the centre of Uppsala. Landowners are the National Heritage Board, the diocese of Uppsala, the university of Uppsala, the local municipality of Uppsala and one private landowner.

Effektivisering av urvalsprocesser vid analysering av björnspillning : Ett förslag till den svenska förvaltningen av brunbjörn Ursus arctos

The aim with this report is to formulate a strategic method to optimize selection processes of DNA-samples from a faeces inventory to identify as many individuals in as few analyzes as possible, and by that keep down the costs of brown bear management. Brown bear management in Sweden founds today on results from faeces inventory and is substantially led by the county administration boards. Data from the years of 2004 and 2009´s inventories in Västerbotten was used to test and evaluate different methods in selection processes of which faeces that should be sampled. Comparison were made between making selection by chance, by spatial distribution and by calculating variations in logistic regressions coefficient b, in other words bear density and probability in finding same individual in several faeces. We can show making selection by chance is the most uncertain method.

Bilderboken i förskolan : Vad pedagoger tar hänsyn till när de väljer böcker

The aim of this study is to increase the knowledge regarding the selection process of picture books by pre-school educators. My intention is to find out which criteria educators use to select the books. I have restricted the study to pre-school educators, because I wish to find out how they work with the selection process and which criteria and considerations are included. I also want to know if the children have influence in the book selection and how the books get to the pre-school.The study is based on qualitative interviews with educators at a pre-schools in my area as well as relevant publications. The questions the educators were given were semi-structured.

Gymnasieungdomars kostvanor under skoldagen och deras uppfattningar om skolkafeteriornas utbud

The aim of this thesis was to investigate whether the selection of products in the school cafeterias in Uppsala county high schools' comply with NFA's (National Food Administration) recommendations. Furthermore, the intention was to examine pupils´ eating habits before and during the school day, and their views on the school cafeteria´s selection of products. To investigate this, an inventory of school cafeterias in six high schools in Uppsala County, and a survey among 60 pupils were carried out. The results showed that the NFA's recommendations not always were followed. The survey showed that there were healthy products in the cafeterias but unhealthy products nevertheless constituted a large part of the selection.

Effekter av "Billigaste väg" för Stora Enso Skogs transportverksamhet :

Transportation constitutes a large part of the forest industry's raw material costs. Transport also contributes a significant proportion of the carbon dioxide emissions. In order to reduce both the cost and environmental impact different types of decision support are required. These, in turn, require extensive information about the road network and correct information on road path selection and transport distances. In the development of national road data base for forestry (SNVDB) a road selection application has been included.

Pre-spawning habitat selection of subarctic brown trout (Salmo trutta L.) in the river Vindelälven, Sweden

Habitat selection of migratory brown trout at the upper reaches of River Vindelälven, wasstudied in September during the pre-spawning period. The fish migrate from down- orupriver lakes for spawning in the river and data was collected by habitat mapping andradio-telemetry. Habitat selection of fish was analysed with preference curves andstatistical modelling, using the physical variables; depth, stream velocity and streambedsubstrate. Preference curves were derived by comparing fish habitat use with their nearbyavailable environment while the statistical modelling aimed to answer three main questions.1) Do the trout have a specific preference of depth, water velocity and streambed substrate?2) Is there any difference in habitat selection between sexes? 3) Is there a shift in habitatselection over time? The preference curves indicated that trout favored water depths of 1-2m, velocity compositions characterized as glides (c.
