Brand i Fulufjällets nationalpark : en brandhistorisk analys med förslag för framtida skötsel

Fire has historically been of great ecological importance in the boreal forests of Sweden. The forest fire regime has, however, varied between different parts of the country. The objective of this thesis is therefore to investigate the fire history in Fulufjället National Park and, on this basis, give suggestions for future fire management. The reconstruction of fire history was done by cross-dating fire scars in samples taken from living and dead Scots pine (Pinus sylvestris). Local fire chronologies were established at 17 points in the forests in and around Fulufjället National Park by cross-dating fire scars on 54 samples. The oldest year-ring dated from year 968.

Konstruktionsforslag for kabelprovningsutrustning av serieresonanstyp

In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined.

Mätning av axiella magnetiska läckflöden i vattenkraftsgeneratorer

This thesis describes a method of measuring axial magnetic leakage flux in an operational hydropower generator. Axial magnetic leakage flux is the magnetic flux at the ends of a rotating generator, which goes through the stator parallel to the rotor axis. This flux can cause circulating currents in the stator iron, giving rise to losses, and can in the worst case overheat a generator, causing it to melt down. To measure the axial flux, and how it affects the generator temperature, a measurement system was constructed on behalf of Vattenfall. The system consists of search coil sensors and a signal-processing unit with amplifiers and active filtering.  To confirm the behaviour of the axial leakage flux and the functionality of the measurement system, a test installation was made.

Utveckling och validering av en LC-MS/MS metod för kvantifiering av clopidogrel och dess metabolit i plasma

Clopidogrel is an antiplatelet substance that prevents blood coagulation in the arteries. It is an inactive pro drug that becomes activated after first-pass metabolism by the liver. The active metabolite of clopidogrel is 2-oxoclopidogrel, which is unstable therefore pharmacokinetic data is obtained by measuring the inactive metabolite clopidogrel acid in plasma. Clopidogrel is taken orally in tablet form. The aim of this project was to develop a LC-MS/MS method for quantification of clopidogrel and its metabolite in plasma. The method has been developed by optimizing the sample preparation.

Relationer mellan kvinnor : Avund och konkurrens mellan kvinnor i Försvarsmakten

Syftet med denna studie är att undersöka kvinnors erfarenheter av konkurrens och avund kvinnor emellan inom Försvarsmakten. Tidigare forskning redovisar att friktioner mellan kvinnor skapas på grund av samhällets genusordning, att kvinnor är det underordnande könet vars prestationer inte värderas samma som männens.  Det visar sig också att kvinnors behov av bekräftelse och identifikation genom andra kvinnor skapar slitningar. En enkätundersökning ifylld av kadetter på alla Försvarsmaktens skolor visar att avund och konkurrens är ett tämligen vanligt förekommande fenomen. De kvinnliga kadetterna upplever att männen bidrar till att skapa avund och konkurrens kvinnor emellan. De uppger även att de i högre grad känner konkurrens gentemot männen på grund av att Försvarsmakten är en organisation gjord av män för män och en frustration bland kvinnorna är uppenbara på grund av kvinnors och mäns olika förutsättningar i Försvarsmakten..

Har vi inte kommit längre än så här? - en studie om jämställdhet i Europaparlamentet

The aim of this thesis is to ascertain if women are discriminated in the European Parliament, and if so, how it is expressed. Our hypothesis is that female members of the parliament suffer a kind of double discrimination. The European Parliament consists of roughly one third women, but nevertheless the discrimination does not end there. According to our hypothesis women do not have the same opportunity to influence as their male colleagues, hence the double discrimination.The results of this thesis show that women are discriminated, mainly by not gaining access to the European Union's important issues, whilst the female dominated issues are scheduled on late evening and at the end of a session week. Another unsatisfactory issue was that even though half of the reports were given by women, they only received one third of the references to their reports while men received two thirds of the references.

Välgrundat och nyanserat? : Tolkning och användning av de nya kunskapskraven för Sh 1b i Gy 11

The purpose of this study is to gain a deeper understanding of women's violence against men in intimate relationships, get an idea of ??what forms of expression that this type of violence has and to highlight the men's experiences of violence.There is little scientific research in the field in Sweden. Crime Prevention Council has determined that eight percent of all complaints involving domestic violence in 2010, reported by men over 18 years. You can only speculate on how large number of unreported cases is among abused men. The international studies highlight that the abused men feel ashamed of having been subjected to violence by a female partner.I have been based this essay on two theoretical premises, Per Isdal theory of "violence perspective" and Elaine Bergqvist's definition of the suppression technique.The study was conducted through a qualitative content analysis.

Matarverk för Camcoil

By our employer Camatec Industriteknik AB have we been given the assignment to continue with the previous work ?Design of strip feeder?. Our goal with this work is to come up with a design basis for a strip feeder.Functionally a strip feeder consists of two rollers which with the aid of the friction between the strip and the coating on the roller create a strip force that pulls the strip through the working progress.Demands on this project:? 10 ? 600 mm in strip width and 0,1-1 mm in strip thickness.? Minimum 30m/min in production speed.? A maximum strip force on 30-40 kN.? The cost of the strip feeder?s components is to be considered of economy and quality.The need of a strip feeder occurs when the coil doesn?t manage to feed or pull the strip before or after a working process. The strip can otherwise be exposed by a permanent yield deformation or a change in the strip material if it?s pulled trough the working process only by the on ? and of-coils.

The project aimed to develop a protective and stabilizing insole called Trailplate for soft andlight shoes. The demand came primarily from off-road runners in France, Switzerland, andAustria. The project was carried out at Icebug, a company that develops shoes mainly forrough terrain. The main focus has been on the trailplate which is designed to fit severaldifferent shoes.Torsional stiffness and bending resistance were the main objectives. To improve the existinginsole, a material with the right features was required.

ADS och Matlab för optimering av pre-distortion av effektförstärkare

This master?s thesis deals with integrating simulations using Agilents Electronic Design Automation tool ADS with customized Matlab scripts, for solving complex analog and digital radio architectures. In particular, it addresses predistortion, realized in the digital domain, of power amplifiers, modeled in the analog domain. The former is implemented in Matlab while the latter is implemented in ADS. Two versions of integrating the two systems have been tested: 1) Iterative approach on sample basis and 2) Scheduled batch solution by matrix inversion.

Design och konstruktion av mätuppställning för induktiv mätning av magnetisk spinndynamik

Development in spin dynamic occurs in the whole world because of therising demands on fast electronic storage for example hard drivesand RAM (Random Access Memory). Measuring the spin resonance of amaterial gives you the insight of the theoretical speed for amagnetic memory. This means the maximum storage speed is below thefirst resonance. All magnetic materials have different propertiesthat will inflict the resonance frequency which brings that theconstructors of memories need to know which magnetic material theywill use to obtain best results. In the market for normal users themaximum storage speed in a RAM memory is 1.6 GHz.

Debatt om informationsfrihet i kris- En studie över upphovsrättsdebatten i några svenska biblioteksorienterade tidskrifter 1996-2001.

In the years 1996-2001 the European Union`s copyright-directive was drawn up. This directive led to much lobbying activities from both copyright holders and library organisations like EBLIDA and IFLA. The Internet and filesharing networks like Napster had led to strong reactions among some copyright holders. Internet gave people an easy opportunity of accessing copyright protected material. Some researchers of copyright have written books where they state that the copyright holders utilize authors fear of illegal copying to strengthen the copyright laws, and by that benefit economical.

Fenylbutazon - tillåta vid tävling?

Phenylbutazone has been discussed in the world of the equestrian sport several times and different countries have diverse opinions on its use in competitions. The progressive list that permits phenylbutazone with plasma levels up to 8 µg/ml was presented at the FEI General Assembly in November 2009. The list was voted to be accepted, but later several countries realized the consequences and after protests the list was rejected and is going to be discussed again at the FEI General Assembly 2010. In this literature study I have studied the relationship between the concentrations of phenylbutazone in plasma and the effects on lameness. The purpose was to establish whether the limit of 8 µg/ml phenylbutazone in plasma affects the equestrian sport.

Brandrelaterade insekters lokala artrikedom i förhållande till olika miljövariabler : Fokus på betydelsen av konnektivitet på brandfält i boreal skog i Västerbottens län

The last century, forest fires have decreased in frequency due to efficient fire-suppression along with the growth of the industrial forestry. Since 1990, fire has been reintroduced under controlled forms to recreate burnt habitats. Many species that are dependent on, or benefits from, forest fires have increased since fire was reintroduced. The importance of connectivity is often addressed in ecological research. This is particularly important for species dependent on short-lived habitats such as burnt forests.
