Mätning av årsringsbredd med laser
Visuella kännetecken på trä kan användas för att försäkra sig om dess
kvalitet, till exempel träets hållfasthet och styvhet. Medelantalet
årsringar i brädan är en av dessa parametrar. Målsättningen i arbetet har
varit att undersöka om det är möjligt att använda mätning med laserpunkter
för att detektera årsringarnas bredd. Idag används en sådan utrustning med
tre laserpunkter i industrin för att mäta fibervinkeln och kärnvedsandel i
plankor vid tvärtransport. I data som innehåller information om
fibervinkeln kan man se ett tydligt brus, som inte är relaterat till
fibervinkeln.
F?RS?LJNING AV OCH INST?LLNING TILL FR?MMANDE V?XTER I TR?DG?RDSBRANSCHEN
Alien plants that have intentionally been introduced to an area for cultivation in public or
private gardens constitute the primary pathway of introduction for invasive alien species that
spread into nature. Garden owners want species that have satisfying characteristics, these
characteristics are often also linked to plant invasiveness. Thus, the horticulture industry plays
an important role by making scientifically based decisions and phasing out invasive plants and
replacing them with alternative species with satisfying characteristics, but low risks of
becoming invasive. This thesis aimed to examine the sale of and the attitudes towards alien
plants in the horticulture industry in Sweden. Alien terrestrial plants identified to have a severe
risk, high risk or potentially high risk of spreading and becoming invasive according to
ArtDatabankens assessment, were examined to see if they were for sale.
Användandet av mobila enheter med appsystem och appars fackmannamässiga potential inom byggbranshen
Mobile devices such as tablets and smartphones are quite common in this day. The author of this thesis wanted to know how common these mobile devices are in the building industry and how they are used and what potential an app could have. The author thus conducted an investigation on this matter, mainly in the form of interviews.Answers given by the interviews were then used as a basis to survey the usage of mobile devices and the usage of different kinds of apps. An investigation of different apps with the potential to be used by professionals in the building industry has been carried through. Apps which manage such things as scanning documents, measuring distances and handle communication.

AbstractWrite the most important things first in text that will be read by a scanning web user. This paper is based upon theories about? how we read? what style in texts is? how texts should be written for web pagesReading from computer screens is about 25 percent slower than reading from paper. This because screens? flicker? have lower resolution than paperAll text with the purpose of being read from a screen should be adjusted to the reader?s physical condition.
Göta älvbron, övervakning med optisk fiber : Ekonomisk analys
The Göta älv-bridge is a welded steelbridge which is located in Gothenburg,it connects the inner city of Gothenburgwith the island Hisingen. Cracks wasdiscovered in the steel in 1999-2000which started an investigation of thebridge to clearify the condition of thebridge. The conclusion was a monitoringsystem based on laser light sent throughan optical fiber.This report describes the bridge, thedamages, the monitoring system and thetraffic on the bridge.Stefan Pup, at Vectura Borlänge was mysupervisor during this work. In myinvestigation the costs of themonitoring system and the costs ofclosing the bridge is compared andevaluated. The biggest investigatingpart is the costs of closing the bridge.The results of my investigations is thatclosing the Göta älv-bridge would cost 1107 300 SEK / day.
Double integrating spheres: A method for assessment of optical properties of biological tissues
The determination of the optical properties of biological tissue is an important issue in laser medicine. The optical properties define the tissue´s absorption and scattering behaviour, and can be expressed by quantities such as the albedo, the optical thickness and the anisotropy coefficient. During this project, a measurement system for the determination of the optical properties was built up. The system consists of a double integrating sphere set-up to perform the necessary reflection and transmission measurements, and a computer algorithm to calculate the optical properties from the measured data. This algorithm is called Inverse Adding Doubling method, and is based on a one-dimensional transport model.
Att spegla sin omvärld ? En exemplifierande fallstudie av Haninge kommuns biblioteksverksamhet
The purpose of this paper is to investigate in which aspects the public library is affected by its local community. This is re-searched by means of an exemplified case study of a Swedish public library in which we analyze governing documents and the library website with respect to environmental scanning and mar-keting of library services.The research questions are: How are the local community?s demands on the public li-brary being described in the governing document? How is the public library?s response to the demands of the local community being described in the operational plan? How are the demands of the local community, as shown in the governing document and the operational plan, re-flected in the marketing of library services on the library website?Our conclusions are that:The demands of the local community are described in a general fashion in the governing document, but there is a lack of concrete political guidelines.The public library's response to the demands of the local commu-nity is described to some length in the operational plan, but not with respect to economical factors.The demands of the local community are reflected to some length in the marketing of library services on the library website. Many of the overall themes that we identify in the governing document and the operational plan can be found in the marketing directed towards important target groups..
Nyetablering i den offentliga sjukvården : hinder på två nivåer
Irradia AB tillverkar och säljer terapeutiska, kirurgiska och kosmetiska lasrar. Företaget har hittills inte lyckats skapa utbyte med den offentliga sjukvårdsmarknaden. Syftet med undersökningen var därför att analysera och utvärdera hinder för Irradia AB:s introduktion på den offentliga svenska sjukvårdsmarknaden. Fokus lades på de terapeutiska lasrarna. På grund av undersökningsområdets natur gjordes en separation av mega- och marknadsnivå.
Inverkan av olika joner och jonconcentrationer på porstorleksfördelningen i trämassa-fibrer
The basic ingredient of paper is the individual wood fibers. The property of the fibers depends on a variety of factors e.g., method of pulp production and processing. The final sheet quality depends in part on how the fibers interface between each other and therefore factors that affect the fiber size are of interest.The flexibility of the fibers depends in part on the pore water i.e., the fiber swelling. The sheet becomes less flexible at low water content which gives a loss in strength. Thus it becomes desirable to increase the water uptake.The experimental investigation described in this report consists of exposing the wood fibers to different ions and ionic strength and then measure the pore size by thermoporosimetry where a DSC (Differential Scanning Calorimeter) is used.
Forskning och museer : en kartläggning av fältet
Today every organization is committed to some kind of environmental scanning in order to get necessary knowledge of the world around them. The acquisition, organization and storage of information in combination with a strategic use, is today an important factor for a successful organisation in any sector of our society.In this Master thesis I have studied how an organisation such as The Confederation of Swedish Enterprise (Svenskt Näringsliv) handles its information resources. I have also looked at the flow of information within the organization. The Confederation of Swedish Enterprise is Sweden?s largest business federation representing 50 member organizations and 55 000 member companies.
Francisella tularensis subspecies holarctica : the curious case of a water- and mosquito associated bacterium in Sweden
Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern
hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of
mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two
prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in
close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.
SEM/EDS-analyser av föremål påträffade i Birka : En jämförande studie
The purpose of this paper was to identify the elements and the alloys that five objects found in Birka consist of and to examine whether there are any significant differences between the presumably imported and domestic objects. The material was analyzed using a scanning electron microscope (SEM) which was equipped with an energy dispersive X-ray spectrometer (EDS) in order to identify the elements that are present and the alloys that the objects are made of. Then the SEM results were compared with the results of previous analyzes that have been performed on finds from Birka in order to investigate how the objects differ in elemental composition and to find out if there are any significant differences between them. The results showed that the objects? content of the elements analyzed varies as the copper alloys the objects are made of.
Frigörelse av kvicksilver och metylkvicksilver till bäckvatten under olika perioder efter skogsavverkning :
High levels of Hg in fish in Swedish lakes have been a problem along time in Sweden. The major concern is production and accumulation of the most toxic form of mercury; methyl mercury (MeHg). Consequently, in about half of our 83 000 lakes fish contain concentrations above the recommended limit for human consumption of 0,5 mg mercury per kg fresh weight (most of it in the form of MeHg). Consumption of fish containing too high levels of MeHg may cause problems for both humans and animals.
Three major sources of MeHg in surface waters are: 1) runoff from terrestrial areas, 2) deposition from the atmosphere, and 3) internal production of MeHg in lakes and streams. The aim of this study was to investigate the effect of clear-cutting on the concentration of Hg and MeHg into draining streams.
Isolating microorganisms from marine and marine-associated samples : a targeted search for novel natural antibiotics
The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens. Microorganisms have been extensively mined for their biosynthetic abilities to produce biologically active compounds. To date, more than 23 000 microbial natural products have been discovered. The Actinomycetales are ubiquitous bacteria that have been used for antibiotic discovery for more than half a century, and over 10 000 natural products have been identified from the order.
