Rotningsstimulerande effekt och kemisk analys av vattenbaserad extraktion av vedartade och örtartade skott av Salix smithiana Willd. :

Cuttings of Lonicera xylosteum L. were treated with willow extract to study the response in rooting capacity. The extracts were prepared by mixing chopped pieces of Salix x smithiana Willd. with water in a warring blender. The investigation comprised 2 types of salix extracts based on differences and dynamics between twigs in winter dormancy and twigs with new shoots. To explore the rooting response, three tests were made.

DMAIC-cykel för justering av parkeringsbroms på Volvo XC90

Sex Sigma är ett förbättringsprogram som först användes av Motorola och genom detta förbättringsprogram förbättrades deras kvalité kraftigt. Sex Sigma ska hjälpa till att producera maximalt, med hjälp av minimala resurser. Genom att använda DMAIC-cykeln (Define, Measure, Analyse, Improve, Control) förbättras nuvarande produkter.Volvo Personvagnars fabrik i Torslanda tillverkar bilar enligt löpandebandprincipen och varje minut kommer en ny bil ut ur fabriken, ungefär varannan är en Volvo XC90. På Volvo XC90 finns det en parkeringsbroms som spänns med en fotpedal och släpps med ett handtag. Eftersom det är en relativt ny modell finns det problem med att få stabilitet i produktionsprocessen, och på en del bilar måste parkeringsbromsen efterjusteras innan de skickas till kund.Syftet med examensarbetet är att ge förbättringsförslag för att minska antalet Volvo XC90 där parkeringsbromsen måste justeras i efterhand efter banans slut innan bilen lämnar fabriken.

Ombyggnad av skolbyggnad för nya verksamheter : En visionsstudie för Wenströmska skolan och dess närområde

New production is not the only thing that is important for the city?s growth. It is also crucial to recover existing buildings in order to create attractive areas. There is a school in Va?stera?s city called Wenstro?mska skolan which consists of six high schools that provide different professional specializations and which has an area of about 35000 square meters.

Biological control of Fusarium wilt on tomatoes : use of Bacillus subtilis and interactions with the earthworm Pontoscolex corethrurus in a Kenyan highland soil

It is important to investigate the potential of biological control measures in agricul-ture, especially where economic issues restrict the use of expensive inputs or when there are environmental concerns about toxicity of agrochemicals. The bacterium Bacillus subtilis has proved promising as a biocontrol agent (BCA) in suppressing various plant diseases and it has also been shown to promote plant growth in certain cases. During this study, the effect of B. subtilis on Fusarium wilt (caused by the fungus Fusarium oxysporum) on tomatoes, as well as its effect on the earthworm species Pontoscolex corethrurus was investigated. Furthermore, the combined ef-fect of the BCA with P.

Skola i Mariehäll

Jag har ritat en skola i Mariehäll. Konceptet för skolan baserar sig på att skolans program delas upp och får rymmas i fyra volymer. Då volymerna förskjuts i relation till varandra skapas mellanrum där skolans kommunikationer sker. Det har varit viktigt att skapa välfungerande och tydliga flöden.Programmet som fördelas i de fyra huskropparna kan grovt delas upp i kategorier. En kategori innehåller utrymmen för personal, administration och lokalvård, en annan ett kulturcentrum och skolrestaurang och en tredje skolbarnens hemvist.

Fire impact in the wood quality and a fertilization experiment in Eucalyptus plantations in Guangxi, southern China

Chinas government has a multifunctional program for a more sustainable forestry since 2000. This six key forest programs goal is to develop a more sustainable forest sector but also take environment consideration. The state forest administration in China has decided to create 5.8 million hectare of fast growing and high yield forest. Eucalyptus has showed to have good properties for pulp and timber production and therefore Eucalyptus plantations are under development in costal areas in southern China. By adding extra nutrients, growth can be enhanced in Eucalyptus plantations.

Skogsskötsel för att minimera stormfällning över järnväg :

The society of today is dependent of secure transports and deliveries of electrical power. Interruptions in different activities because of fallen trees cost a great deal of money in form of reparations and claimed damages for transport companies and electrical suppliers. Fallen trees along some railway sections are a severe problem. For instance, to repair the damages of the storm of week 5 year 2002, costed 2 800 000 SEK for the line region of Hässleholm. Today, the Banverket railroad company has no norms in general for how close to the railway the forest is allowed to grow.

Migration och vegetationsupptag av radiocesium i åkermark - en långtidsserie av mätdata samt en långsiktig simuleringsmodell :

Abstract The accident in 1986 at the nuclear power station in Chernobyl, Ukraine, dispersed radioactive cesium over large areas of Europe. The half life of 137Cs is 30 years and this radionuclide also behaves like potassium, which means that it can easily be taken up by the vegetation or be adsorbed in to the structure of clays, principally illitic clays. When radiocesium decays ionizing radiation is emitted, which is harmful to humans that are exposed, either directly or indirectly through food intake. It is there-fore important to know what happens to the cesium that is dispersed into the environ-ment. In this project a simulation model was constructed to simulate the adsorption and transport of radiocesium in the soil and plant uptake.

Potatis, marknad och konsumtion i dagens Malmö :

I want to find the meaning of food ?potato in today?s society. How about marketing and how does potato consumes? What can be done to achieve better competitiveness towards other products now and in the future? I will build this project on a statistic ground ?now and then? as well as a study to people outside various food- markets. The consumers answers will state my foundation in this project.

Ljusets betydelse för rotknoppars groningsvillighet i åkermolke (Sonchus arvensis L.)

This study is about how changed light conditions induce dormancy in plants. It is divided in two parts. First a literature study where quantification of light, the concept dormancy, photoperiod and light quality are discussed. Second an experimental part, where the importance of light for sprouting capacity in root buds of perennial sow thistle (Sonchus arvensis L.) is investigated.In the science in how flowering in plants are induced the concepts short day/long day plants and light dominant/dark dominant are well-established. These concepts can also be applied to how light induce dormancy in plants.

Med staden som förebild : reflektioner kring det stadsmässiga

This master thesis starts in a wondering about the visions and ideas we have about thecity and about the urban. In Swedish about the term stadsmässighet, which can be translatedin to city-like, urban or urbanely, something that describes or contains features ofthe city. How do we use the city as a role model? Is urbane building the same as buildinga city? Is it about architecture and aesthetics or is building urbanely the way to makepopular cities? The central aim of this essay is to study visions and reality around urbanebuilding in order to understand the concept?s meaning and how it changes. My ambitionis that the essay will function as a discussion basis for students and planners.The work starts with literature studies where theoretical definitions and concepts aboutcities and about the urbane is investigated.
