Functional diversity of evertebrates in different types of beech forest in southern Sweden

Populärvetenskaplig sammanfattning: De skånska bokskogarna. Vad kan krypen säga? Det är mycket som påverkar våra skogar i dag. Vägar som delar upp dem i mindre delar och lantbruk och kvävenedfall som stör balansen för vad som ska växa i skogens utkanter med sin gödsling. Även trafiken påverkar genom att kväveoxiderna i avgaserna har en gödande effekt. Skogens hälsa påverkas självklart av detta, Abstract Deforestation, fragmentation and loss of biodiversity, all are elements that are common today. With this project I want to evaluate if there is a difference in functional diversity of evertebrates between beech stands of low herb and shrub type beech forest. I also want to test if there is a difference within tested areas between low herb and shrub type forests, but also if here is a dif

PROCESSUTVECKLING FÖR JÄRNBASERADE HÅRDMAGNETISKA PULVER UTAN SÄLLSYNTA JORDARTSMETALLER

An experimental study was performed, aimed at finding a way to produce single crystalline powder of pure (Fe0.7Co0.3)2B with a particle size of 100-200nm. This was done with the ultimate goal of producing a hard magnetic ferrite powder for powder metallurgical production of permanent magnets. For this study, eight different compositions of iron, cobalt and boron were atomized using atomization by

In Vitro Studies on the Uptake of Ion-X-Gel Precursor and SPIO by Various Cell Types

Popular science summary: The Battle Against Cancer Daily, people are diagnosed with cancer, a disease that brings suffering and despair. I'm sure you have heard about chemotherapy and radiation as a way of trying to treat cancer, but it is equally important to find an effective method to quickly and reliably detect a tumor at an early stage, before it is too late. In my master's thesis,

“We will be there soon. Sawa*? Sawa?” A study on increased ICT use among secondary school students in Mutomo

Africa stands on the doorstep of a global information revolution that presents a range of opportu-nities. ICT has enormous potential to contribute to the development of Africa, both on an indi-vidual and societal level. The purpose of this study is to examine what effect increased ICT use has on secondary school students in Mutomo, Kenya. Furthermore the study presents a mapping of the secondary s

Ett planeringsverktyg för urbana ekosystemtjänster - En länk mellan naturvetenskap och beslutsfattande

This master thesis explores the concept of ecosystem services, in the context of urban planning in Swedish municipalities, with the purpose of putting together a planning development tool for urban ecosystem services. The working process consisted of three steps: (1) to identify problems in the Swedish planning process, (2) to identify relevant aspects of ecosystem services and comprehensive plann

A model to Predict Churn

This Master Thesis has been performed at Svenska Spel with the aim to detect playing customers probability to churn, i.e. quit their gambling. The first part of the Thesis consists of some previously work done within the field, some facts about Svenska Spel and explanations of used software. The next part describes how the work has been done and the third part give the reader the theory behind the

Optimization of paper pulp production using Artificial Neural Networks and Simulated Annealing

The purpose of this paper is to investigate the possibilities of optimizing the production of paper pulp in a Conical Disc (CD) refiner for different production rates, taking into account the variables that are thought to be the most important for the production. These include three separate dilution waters, conical disc gap and flat gap. Another task is to compare the values of these variables af

Premiecykler på den svenska skadeförsäkringsmarknaden

Denna uppsats har haft som ändamål att undersöka om den svenska skadeförsäkringsmarknaden har karakteriserats av en premiecykel under åren 1988 – 2012. Utifrån tidigare forskning har teorier diskuterats vilka förklarar olika skäl till varför premier på försäkringsmarknaden tenderar att röra sig i cykler. Uppsatsen visar med hjälp av en autoregressiv model att den svenska marknaden, i likhet med va

Development of a temperature control system for spectroscopic measurements with rare-earth doped crystals

This thesis describes the development of a temperature control system for optical spectroscopy experiments with rare-earth doped samples. Low temperature emission spectra were afterwards recorded for a series for Eu3+ singly doped and Ce3+, Eu3+ codoped Y2SiO5 samples. The analysis and assignment of the different energy transitions is presented. The experimental setups used in this thesis involve

M-step Bootstrap Percolation on Z1

We study an extended bootstrap percolation process in several steps in dimension one, assuming noncyclic boundary conditions. We study the asymptotic behavior of the process as the size of the underlying graph goes to innity. We nd a phase transition with respect to the initial conditions. The phase diagram on the set of initial conditionals of the extended process is described completely. This pr

Implementation av SCORM 2004 API och Datamodell i .NET

The thesis treats a partial implementation of the SCORM standard for an existing LMS (Learning Management System), and includes an overview of the standard and a presentation and analysis of the implementation. SCORM is short for Shareable Content Object Reference Model and is a standard for web based e-learning. The standard specifies, among other things, API, aggregation and data model. The impl

Evaluating habitat suitability and spectral heterogeneity models to predict weed species presence

The aim of this study is to analyze whether the presence of weed species resistant to herbicides is related to landscape heterogeneity and environmental variables. C3 and C4 weed species, such as Chenopodium album, Conyza canadensis, Amaranthus retroflexus, Papaver rhoeas, Sorghum halepense, Echinochloa crus-galli and Lolium rigidum, are studied in two differing bioclimatic countries, Greece and G

Antireflection Patterning of Si for InAsSb Nanowire Infrared Photodetectors

The pattering of an optical surface with physical features like with very low reflectivity and high transmission of IR or visible light can be used e.g. for antireflective windows for solar cells and photodetectors. Here we present results on antireflective patterning of Si for back side illuminated InAsSb nanowire long wavelength IR (8-15 µm) photodetectors. Photolithography and dry etching techn

Ätstörningar hos unga med diabetes mellitus typ 1- En litteraturstudie

Utvecklandet av diabetes och ätstörningar sammanfaller ofta kring pubertetsåldern hos både unga kvinnor och män. Då prevalensen av både diabetes typ 1 och ätstörningar ökar kan det vara intressant att studera ett eventuellt samband. Syftet med studien var att sammanställa forskningsresultat kring ätstörningar hos unga personer med diabetes mellitus typ 1. Studien genomfördes som en litteraturstudi

Sjuksköterskans följsamhet till handhygien

Även om sjuksköterskan är medvetet om hygienens betydelse i sitt dagliga omvårdnadsarbete är följsamheten till handhygien fortfarande låg. Vårdrelaterade infektioner är fortfarande ett stort problem inom hälso-och sjukvården. Syftet med denna litteraturstudie var att belysa faktorer som påverkar sjuksköterskans följsamhet till handhygien. Metoden var en litteraturstudie som baseras på ett urval av

Does travelling foster international trade?

The world´s total expenditures regarding leisure travelling and related expenditures corresponded to approximately 3000 billions USD in 2010. This substantial value makes the travelling industry and related markets important in an economic aspect. Data posted by the WTO states that between the years of 1995-2005 the world’s amount of tourism arrivals increased by approximately 50 %, and additional

Smärtbedömning av person med demenssjukdom

Smärta är problematiskt vad gäller personer med demens då deras kognitiva förmåga gör det svårt för dem att förmedla sina upplevelser av smärta. Detta ställer särskilda krav på sjuksköterskan och annan hälso- och sjukvårdspersonal eftersom upplevelse av smärta förmedlas på andra sätt och därför måste observeras. Syftet med denna studie var att belysa olika smärtskattningsskalor samt belysa faktore

Musik: Komplementär smärtlindring vid cancerrelaterad smärta

För patienter med cancer är cancerrelaterad smärta ett vanligt problem som orsakar ett stort lidande. Syftet var att beskriva användandet av musik i förhållande till omvårdnad av vuxna patienter med cancerrelaterad smärta. Resultatet visade genom teman att musiken kunde lindra såväl fysisk som psykisk/emotionell cancerrelaterad smärta samt att användningen och graden av smärtlindring påverkas av s
