Under år 2007 observerades dålig etablering och svag tillväxt hos blålupin i ett odlingssystemsförsök i Bollerup, Skåne. Förfrukten var hampa. I led med sockerbetor som förfrukt var blålupinetableringen god och visade inga tecken på försämrad uppkomst eller tillväxt. Samma iakttagelse gjordes år 2008. En misstanke väcktes då om att baljväxters etablering och tillväxt blir tillbakasatt av att odlas I en växtföljd med industrihampa på grund av dess allelopatiska ämnen.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

The subject of this bachelors degree project is an interior layout for road ambulances.Landstinget Västernorrland (LVN) wanted a layout concept that would be used to com- municate their design intentions to the ambulance producers during their purchase process.Designing ambulance interiors is an extremely complex process since there so many fac- tors to take into consideration. It ?s not just about taking the equipment and place it where there is space left in the cabin. You have to start with the user in focus and the tasks that are to be performed in the ambulance environment.It ishard to find design solutions that will fit 100% of the ambulance personnel?s working routines for 100% of the tasks.

VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.

Bakgrund: Butikerna inom detaljhandeln har svårigheter med att effektivisera utbytesplatsen. I och med den ökade konkurrensen som råder på marknaden blir det svårt för små- och medelstora företag att överleva. Detta tillsammans med att konsumenterna avskärmar sig från den stora massan av reklam och marknadsföring som de dagligen utsätts för har lett till att företag måste hitta nya unika sätt att marknadsföra sig på för att överleva långsiktigt.Problemformulering: Vilka faktorer är viktiga för att påverka köpprocessen i en butik genom att använda doft som marknadsföringsfenomen?Syfte: Syftet med vår undersökning är att studera kausala samband mellan hur vår oberoende variabel, doft, påverkar den beroende variabeln, köpprocess.Metod: Uppsatsen utgår från en deduktiv ansats. Vi kommer att göra ett experiment och utgå från en kvantitativ metod med kvalitativa inslag.

Enligt forskning har riktig natur och bilder av natur en avstressande effekt på människor i sjukhusmiljö. Stenpartier byggs ofta för att simulera naturliga förhållanden och kan upplevas som en tredimensionell landskapsmålning som förändras med årstidens växlingar.Syftet med denna studie är att komma fram till en gestaltningsskiss med hjälp av sten och stenpartiväxter. Gestaltningen tänkta plats är utanför Gävle sjukhus. Fokus har lagts på stenpartiets uppbyggnad, växternas krav och anpassningen till sjukhusmiljön.För att ta reda på ett stenpartis uppbyggnad och stenpartiväxters krav på växtmiljö har både en litteraturstudie och platsbesök med intervjuer gjorts. Litteraturen är sökt via LIBRIS.

In Sweden and in Scandinavia the amount of tree species are rather few. However many different forms of trees arise due to mutations and gives rare appearances like cut-leaved and hanging forms. In some cases these trees are interesting as cultivars and a few of them have become popular garden trees. The knowledge of the original trees and early propagation is meagre.In this study a selected group of trees were found through search of literature. Eight tree forms were chosen and investigated in situ.

Förr hade man inte problem med dagvattenhantering, eftersom den största delen av marken var infiltreringsbar, men när städerna började exploatera på 1900-talet, ökade hårda ytor som är en av de viktigaste bidragande orsakerna till dagvattenflödeökning. Sverige började tänka på framtiden och man försökte hitta de bästa lösningarna för att kunna göra städerna hållbara. Dagvattenhantering var en av de viktigaste beståndsdelarna i en hållbar utveckling och av den anledningen, började man tänka på möjligheten att hantera dagvatten lokalt. Malmö var en av de kommuner som började använda de ekologiska dagvattenlösningarna. Att använda öppna dagvattensystem var ett av de första valen i Malmö kommun för att minska översvämningsrisken, och förbättra stadens bild genom att öka det estetiska värdet.

European Union has made a new decision that all new built houses by 2020 shallbe near-zero energy houses. Boverket?s definition of near-zero energy housesintends buildings with good energy performance in which a proportion of theamount of energy that must be added to the building is made of renewable energy.Passive House is a set of requirements from FEBY designed to build energyefficient buildings. This is achieved by reducing loss of heat through the buildingenvelope and to take advantage of the passive heat from solar radiation,installation and heat sources like people living in the house.This project has been made with help of Anebyhus and one of their model houseshave been examined from the report?s issues, including Anebyhus?s energyperformance, requirements for the manufacturing and assembly, how theenvelope must be improved to fulfill the requirements for the Passive House andwhat energy calculation programs are available on the market.The report aims to provide solutions for energy efficient houses that are adaptedfor production of house building.Two visits to Anebyhus has been done to study their manufacture and assemblyof building elements.

Denna uppsats tar upp vikten av utevistelse för äldre med demenssjukdomar och trycker på trädgården som en hjälp i arbetet att stärka livskvaliteten. Arbetet är en litteratursökning där material tagits fram enligt snöbollseffekten och resultatet mynnat ut i riktlinjer för design av en demensanpassad trädgård. Här berörs behovet av trygghet och självständighet hos den sjuka. En person med demens behöver en lugn, men samtidigt stimulerande miljö i sin vardag. Forskning har visat att utevistelse i trädgård har en positiv effekt. Genom att använda olika igenkännbara element i trädgården går det att skapa en miljö som den boende känner sig trygg och kan orientera sig i.

Cooling down the indoor air can be done in several ways. One way is desiccantcooling which will be used at the Stockholm Arena. This method is used in airhandling units that use temperature changes and moisture fluctuations in the air. Oneof the steps is to add heat during the cooling process in order to reduce the relativehumidity of the exhaust air. The air passes thru an adsorptions rotor which thenabsorbs moisture from the supply air.

Sweden has distinct seasons with cold winter and temperatures down to minus 25 ?C andpleasant summers with temperatures above 20 ?C. During spring and autumn there could becomechallenges with precipitation. The diverse climate in Sweden affects many homeowners. For thepeople living in leisure boats and permanent housing boats the seasonal changes are clearlyimpacting their economy and the indoor climate.

The aim of this study is to make clear the conception ?Sustainable Urban Development? through an investigation dealing with how the sustainable goals are attained in today?s Swedish urban planning. And also try to clarify where and why sustainable development is failing or lacking. Besides that I have investigated how actors take position towards urban sustainability. The essay is based on a literature study about sustainable urban development and it?s changes through the time and place.
