Färgval hos blomkrabbspindeln (Misumena vatia) med och utan konkurrens

The colour choice of spiders and the effects of competition on this phenomenon were examined in the laboratory using the sit-and-wait predator goldenrod crab spider (Misumena vatia, (Thomisidae)). This species can  be both white and yellow (could also change colour)  and it was here examined whether individuals preferred to sit on flowers which has the same colouration as their bodies. I found that M.vatia showed preference for flowers that matched their own body colour, but when competition was introduced this preference disappear. It seems, however, that position is a factor that can influences the substrate decisions of M. vatia, where the edge of the flower is preferred..

Suitability analysis of a reintroduction of the great bustard (Otis tarda) to Sweden

The great bustard (Otis tarda) became extinct in Sweden during the mid-19th century. Globally, populations have suffered dramatic declines during the past two centuries. Recently, local populations have stabilized or increased after hunting bans and conservation efforts. Despite positive trends the species is still classified by IUCN as vulnerable (VU), mainly due to withdrawals in the distribution. The limited distribution emphasizes the need for finding ?new? areas suitable for a translocation or reintroduction.

Syntetiska Instrument

This thesis aims to investigate SAAB AB´s possibilities to use synthetic instruments in their test systems. The reason for this is reducing costs and the risk of obsolescence which is common when test systems operate for several decades.The market around synthetic instruments has been explored in the search for suitable hardware and software. Software has been developed in LabVIEW and synthetic instruments have been created with the help of IVI-drivers. The hardware consisted of PXI-instruments (Waveform generator and Digitizer), connected to a computer using a fiber optic link and PXI-chassi. The created instruments was then compared to common instruments used today, and the comparison turned out well.

Schemaläggning av hissar vid prioritetsanrop : En studie i hantering av prioritetsanrop av hissar på svenska sjukhus vilka styrs av Nearest Car Algorithm

In our modern society, time is important. Technology is used in countless ways to faster get us from one point to another. The purpose of this report is to inquire whether there is a way to implement an option for personnel at Swedish hospitals to claim priority on an elevator call, and to do this in an efficient way. An ordinary elevator system has been simulated with an implementation of textit{Nearest Car algorithm}, an algorithm which calculates the most suitable elevator car to serve a specific call considering the distance between the call floor and the car and the direction. Along with this algorithm, different ways to handle priority calls has been implemented to see how they affect the mean transport time for both passengers with priority and regular passengers in the elevator.

Miljö- och hälsoskyddskontorets tillsynsarbete - ur verksamhetsövarens perspektiv

Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant.  In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.

Islam och Demokrati : Två olika idè och tanketraditioner?

The purpose of this paper is to study the subject Islam and Democracy and see whatcommonalities exist between the two ideas and traditions of thoughts. The subject is topicaland often highlighted by the media in the West. The Islamic voices that we hear today iscertainly not democratic, given the violence and hatred carried out by Islamic extremistsagainst the West. The investigation of this paper have shown a different direction when thereare other voices such as those investigated reformist thinkers who argue that Islam has manydemocratic elements, and even that Islam is more suitable than democracy. According to thereformists ismodel of an Islamic state is democratic and legitimate.

Måltidsmönster, kost - och - medievanor bland överviktiga 15-åriga flickor och pojkar

Objective: The aim of this study was to compare equations used to calculate BMR to values of BMR obtained from measurements in order to determine the most suitable equation to be used on children and adolescents with CF.Design: The participants where children and adolescents with CF. Data was collected from the division of Clinical Nutrition at Uppsala Akademiska Sjukhus. Age, weight, height, BMI, BMR, FFM and FM was recorded from 27 measurements. BMR from the participants collected from the indirect respiratory calorimetry was compared to the results obtained from five equations used to obtain a calculated value of BMR.Results: Tverskayas equation was best correlated with the measured BMR for the whole group. The equation underestimated BMR for the participants with a measured BMR over 1400 kcal/24h and overestimated BMR for participants with a measured BMR under 1400 kcal/24h.

Biogasproduktion genom tvåstegsrötning av drankvatten

During the 19-century a global warming has been observed, which includes increases in global air and ocean temperatures, widespread melting of ice and snow, and rising global sea level. There is a clear connection between emissions of greenhouse gases caused by the human and the increase in temperature. Climatic changes caused by global warming can be stopped trough decreased emission of fossil fuels, for example by an increased use of biogas. Biogas is a renewable energy source which is produced through anaerobic (oxygen free) digestion of organic material. The gas is a mixture of methane (CH4) and carbon dioxide (CO2) and can be among others used as fuel in vehicles.

Ett steg närmare Just-in-Time : En studie av JIT-försörjning vid GGP Sweden AB

This study looks into the possibility, and profitability, of expanding a pilot project that has been put into action at GGP Sweden AB in Tranås, a manufacturing company that produces front mowers. The pilot project is meant to give GGP Sweden AB a more precise control of the flow of goods from their suppliers, and its essence has proven to be quite similar to the Japanese Just-in-Time philosophy.The study has been divided into four separate areas; mapping, supplier selection, supplier evaluation and cost analysis. These areas represent a holistic perspective on the expansion of the pilot project and cover topics varying from methods of finding suitable JIT-suppliers, constructing Key Performance Indicators (KPI) to reviewing costs and assessing profitabilities.In this report, the reader will initially take part in the works of mapping GGP?s manufacturing unit, pilot project and supplier base, which results in a list containing the most suitable suppliers for a Just-in-Time based collaboration. Afterwards, the reader will be led into the area of supplier evaluation, where five KPI?s are created with the purpose of ensuring that GGP will be able to evaluate their suppliers and pilot project in an effective way.

Jobbcoachning- en skjuts i karriären eller en lindring i misären - En kvalitativ studie av jobbcoachningens roll på arbetsmarknaden

This paper examines job coaching on the Swedish labour market. The study uses trygghetsråden, which are organizations established by an agreement from the labour and employer side, as a starting point for the study. In addition, the study examines the phenomenon from the perspective of the job coaches themselves and the coaches clients. The study concludes that job coaching is defined by the coach and the client's common goal of finding a suitable match for the client on the labour market. The job coach helps the client reach the goal of an appropriate job by making him or her aware of his or her competences and preferences.

Död ved i gallrad skog och nyckelbiotoper : en jämförelse av habitatkvaliteter för vedlevande lavar och mossor

A high amount of dead wood is one of the most important prerequisites for high biodiversity on forest land in Sweden. Dead wood is most abundant in young forests, thinned forests, woodland key habitats and protected forest land. In old-growth forests most of the dead wood consists of logs and snags, whilst in managed forests a huge proportion of dead wood is made up of logging residues like stumps and FWD, fine woody debris (< 10 cm diameter). All these different types of dead wood may serve as substrates for epixylic bryophytes and lichens. However, few studies have been conducted on the relative importance of these different fractions of dead wood for the occurrence of bryophytes and lichens, especially when considering dead wood on thinned forest land.

Hur stor areal äldre skog lämplig för trakthyggesbruk finns det på Gotland 2013?

The degree project at hand investigates how large areas of older forest (80 plus years) suitable for clear cutting there is on the Swedish island of Gotland. Large areas of older forest on Gotland are situated on land with shallow soil depths which are economically uninteresting and often unsuitable for clear cutting forestry. Other forests hold big nature conservation values and should not, or cannot, be used for forestry purposes. The survey is made as a GIS analysis based on the old but carefully made ?Brief forest inventory? (ÖSI) made in the 1980s and early 1990s. A sample from the inventory is combined with studies of orthophotos, satellite photos and other GIS layers that display estimated soil depth and nature conservation values. Partly contrary to common belief, the survey shows that there are still large areas of older forest suitable for clear cutting forestry on the island.
