Att gestalta en socialt hållbar begravningsplats

This thesis aims to present the essential background on how to perform climate changeimpact assessments, and to present the results from a climate impact assessment on waterbalance and nitrate leaching for an arable Swedish soil. The soil is a sandy soil in southwesternSweden, grown with spring cereals. This study is meant to be a benchmark example,and cannot be seen as a regional or national assessment for Sweden, rather as an approachto present and analyze the most important parts of these kinds of assessments.A dynamical simulation model (COUP, Jansson and Karlberg, 2004) was used for thisstudy. The model was parameterized and calibrated against data from an experimental site,located in Mellby in Hallands county, south western Sweden. Measurements were carriedout between 1st of April 1988 and 1st of April 1991.

Water balance and nitrate leaching from arable land in a changed climate : a model study

Utveckling av differentierade transportersättningar för rundvirskestransporter med lastbil

Approximately 60 million cubic meters of round wood are transported every year with trucks in Sweden and stand for 15 % of all truck transportation in the country. The big amount that is transported results in many haulage companies works in different parts of the country with different conditions to get a good flow on their transports. Today the transport pricing is very general and the payment consists of the unit round wood they are transporting and the distance of the transport. The purpose of this study were, from the freighter and the haulage company?s perspective, try to find ways to change the today applied transport pricing to more differentiated and compare them to historic payment of transportation.

Effects of ten year old enrichment plantings in a secondary dipterocarp rainforest : a case study of stem and species distribution in Sabah, Malaysia

Large areas of forests in the tropical region have during the last decades been lost and converted to new land uses while other areas have been degraded into secondary forests. These secondary forests need to be restored and rehabilitation through enrichment planting and liberation may help to speed up the recovery process. The objective of this thesis was to evaluate a rehabilitation method that includes enrichment planting, slashing of weeds and girdling of unwanted trees. The site for the project is situated in Sabah, Borneo in a secondary forest which had been logged and burnt by a wildfire. The project?s goal is to rehabilitate and increase biodiversity through enrichment planting of seedlings mainly belonging to the family Dipterocarpeaceae (dipterocarps).

Läshastighet i en bok, på en dator och i en smartphone ? en fallstudie av fem flickor - Reading speed in a book, a computer and a smartphone - A case study of five girls

Arbetet behandlar frågan om elever läser olika snabbt beroende på varifrån de läser en text? Studiens grundläggande syfte är att undersöka om det föreligger någon skillnad i läshastighet i en bok, på en dator eller i en så kallad smartphone? Undersökningsgruppen är fem slumpmässigt utvalda flickor i årskurs 8. Intresset för arbetet tar sin grund i ett stort eget intresse för läsning men också i deltagande vid insamlandet av data till en större studie i ämnet. Studien har för avsikt att jämföra lästeknik och förståelse i en bok, på en dator och i smartphones. Som en del två skall försök göras för att utveckla lästekniken genom mental teknik- lånad från idrotten - i avsikt att utveckla elevers läsförmåga och uppfattningsmöjlighet. Metoden som används i är i detta arbete en fallstudie samt en analys utifrån observationer av deltagarna.

Miljöhänsyn vid offentlig upphandling :

One of the biggest challenges in the human history is to prevent environmental pollution. Everybody has an indirect or direct influence on the environment through his or her consumption. The stakeholders are not just interested in price and quality, they are also interested in the circumstances of production and how this affects the environment. By taking environmental concern in public procurement it is possible to speed up the environmental adjustment of services and products. Environmental awareness has become more and more self evident in the environmental work.

MÄTNING AV LJUDIMMISSION FRÅN VINDKRAFT. VIDAREUTVECKLING AV METOD FÖR MÄTNING

The Swedish government have a goal that wind turbines shall produce 30 TWh by the year 2020, compared to about 3,5 TWh produced in Sweden during 2010. To minimize the disturbance that wind turbines create the Swedish Environmental Protection Agency has stated a guideline value that noise from wind turbines at nearby residents shouldn?t exceed 40 dBA, at 8 m/s wind speed. With advanced calculation models, like Nord 2000, the emitted sound from future wind turbines can be calculated at an early stage to optimize the power production without exceeding the 40 dBA. When the turbines have been built there is a need to verify that they really are within the guideline.

Fälttest av en ny metod att med objektiva mätmetoder karaktärisera egenskaperna hos ridunderlag- en pilotstudie. :

Background Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses. The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.

CFD simulering av kallras : Undersökning av temperatur- och luftbeteende intill höga glasfasader och i vistelsezon med golvvärme som en värmekälla

Glass has sophisticated front properties and are used as facades in high buildings. During cold periods, these glass facades could cause thermal discomfort, due to cold downdraught. Cold downdraught can be countered by placing heaters under glass surfaces. Nowadays technology offers highly insulating windows, which is why there is an interest to investigate the indoor climate with only underfloor heating. The research in this area is limited, and few empirical methods are available.

Tekniska möjligheter för artificiell spridning av renlav :

Forestry and reindeer husbandry are entitled to use the same land for their operations. For this reason, conflicts occasionally arise between them. Soil scarification is a forestry operation which has a negative effect on the occurrence of reindeer lichen. Reindeer lichens are of crucial importance to reindeers and reindeer husbandry, especially in the winter when reindeers primarily feed on different lichen species (Cladina spp. and Cetraria spp.).

Metodikstudie av trollingfisket i Vänern : Jämförelse av fångstrapportering mellan intervjuer och enkäter gjorda på trollingfiskare samt vädrets påverkan på ansträngning

There are five endemic populations of migratory Atlantic salmon (Salmo salar, Salmonidae) and brown trout (Salmo trutta, Salmonidae) remaining in Lake Vänern, whereof two are salmon and three are trout. There is one population of each species in Klarälven, also one of each in Gullspångsälven and there is a population of trout still remaining in Tidan River. Since the beginning of the 20th century endemic populations of salmon and trout have either vanished or declined dramatically due to the construction of hydropower in the rivers around the lake, and still today the future of the remaining populations remains uncertain. To manage salmonid fishes effectively more knowledge of their ecology throughout their different life-stages is needed. A large part of the Lake Vänern salmonoids lives are spent in the lake, where a mayor mortality factor is recreational fishing, especially angling.

PR och marknadsföring inom sociala medier : En studie kring riskerna att vara social i sociala medier

Social media provides a new position of power to the single individual within PR and marketing campaigns. When a company uses social media as a communication tool in their PR and marketing practice, they have to adapt themselves after the customers' needs and the new communication structure within social media. Communication in social medi is different from traditional media, which is more one-way communicative and visual in its interaction, rather than the digital media that are more two-way communicative av viral through dialogue. If a company creates PR and marketing campaigns within social media without adjusting to the new rules of communication through dialogue, and instead try to apply traditional one-way communication to their social campaigns, they put themselves and their brands in risk of public humiliation and loss of customers; the speed of the viral dialogue over social media can spread bad news fast, and with the newfound power of the single individual, the impliacations can thus be devastating for a company and its brand. If an organization does not respond and take part of the criticism that may be directed at them through the customers' comments, the negative dialogue among clients and the public within social media can quickly create a hazard enviorment for a company and its brand to be seen in. The public within these social media platforms are more independent and continuously conversing with each other on a local an global scale.

Industriella distributionssystem för kyla : Kartläggning,injustering och varvtalsreglering

De flesta industrier har någon typ av kylsystem som betjänar industriella processer och komfortkyla. Funktion och effektivitet på systemen varierar och när kylproblematik uppstår på anläggningen kan anledningarna vara flera. Kylproblematiken kan bero på bristande kylkapacitet, felaktigt injusterade köldbärarflöden eller underdimensionering av distributionssystem samt cirkulationspump.Detta examensarbete har utförts i samarbete med Stora Enso Skoghall och syftet med studien är att kartlägga och analysera deras kylsystems kapacitet, både sett till producerad kyleffekt och möjligheter till distribution på anläggningen. Genom en ökad kännedom av systemets funktion kan optimeringsförslag arbetas fram för att minska risken för kylproblematik och kostsam produktionsbegränsning. Då distributionssystemet är äldre och påbyggt i etapper finns misstankar om att det även finns möjligheter att med modern teknik få systemet att bli mer energieffektivt.

Kulturell Globalisering : en litteraturstudie

Today we are living in a time were impulses from other places and cultures constantly grow and the contact over the boundary is getting bigger. We se satellites pictures over the world, we hear about worldwide ecological problems, we learn about other different lifestyles, we cock food that are inspired from the worlds many kitchens, we shop more and we can travel to different parts of the world. My problem was to find out how cultural phenomenon spreads to a greater extent global and how this transference take place, but also be able to se what factors that has a part in the cultural spread.What I found with help from my literature study was that trough improved communication and transports has gained mobility in the world and people can take part off others culture.The world is shrinking and this means that human beings identity is changing and this create a so-called hybrid mixture. Culture is what we human beings create. Culture can be seen as a community phenomenon for the most parts.

Perenndatabasen : för landskapsarkitektstudenter på Ultuna

This paper constitutes graduate work at the Depart-ment of Urban and Rural Development at the Swedish University of Agricultural Sciences. In this paper the urban structure of the million program suburb Husby in Stockholm is examined and what effect this structure has on social life in the area. The main objective of the study has been to, with the help of morphological analyses, examine how to create meeting places and make the Husby Park more accessiblefor the inhabitants in Husby. There has been a selection of analyses to ensure that Husby?s spatial relationship with surrounding suburbs as well as local spaces in the Husby Park is described.
