This is a paper about the effects from smoldering fire on lithic objects from an archaeological view. The introduction gives the background to this paper, a short orientation to forest wildfires and why the work is limited to: flint, quartz, quartzite and slate. Material and methods describes the stone materials and the setup that was used in the temperature logged tests with three replications for each type of material. The fuel in the burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials.

The purpose of this study was to investigate how the adult world is produced in the books of Martin Widmark about LasseMajas detektivbyrå from a gender perspective.I wanted to answer questions concerning the appearance, personal characteristics, occupations and activities, and the relationship between children and adults to do my analysis.I decided to make a qualitative content analysis to answer my questions.I used the gender theories that describe how stereotypes excel. I related these gender theories to the books that I have studied.I also used previous research on gender roles in other children's books to compare their results with mine.After reading, analyzing and comparing the books I have come to the conclusion that gender roles in books about LasseMajas detektivbyrå is very gender stereotyped..

Concrete is a very common construction material. It´s characteristics are strength, durability and formablility. Superplasticizer is a common admixture, which changes the properties of concrete. Today (spring 2007) there are no certian mathematical methods to calculate the required percentage of this admixture needed to give the necessary set slump flow in the overall concrete recipe. Concrete batching companies must therefor experiment with different amount of superplasticizer in order to meet the specified slump and strength. The purpose og this report is to investigate if any mathematical relation can be established between the amount of superplasticizer used and the slump flow achieved. After carrying out some practical experiments using four different superplasticizers a direct relationship can be establish between the percentage of admixture used and the slump/flowability achieved. Unfortunatly at present due to the numerous variables, the calculation of mathematical formula can not be achieved..

The purpose with this thesis is to illustrate companies? way of using Key Account Management in the organization. We developed the four following research questions: Why do companies choose to use Key Account Management? How do companies identify and choose their key customers? How does a key account manager work? How do the skills needed by a key account manager look like? The results showed that KAM offered several important benefits, mainly of economical characteristics. Identification of the key accounts was mainly conducted through certain economical criteria the customers had to fulfil.

This thesis is made on behalf of SCA's Forestry Division and is a comparison of two bucking simulation tools: Aptan (manufactured by Skogforsk) and Best/upr (from Berget Systemdesign). The data is based on 32 stands from SCA's forests in Norrbotten and Västerbotten. The objective is to compare the simulations created by the tools with the harvested volumes from those stands. Three variables are needed for the bucking simulation; these are the diameter distribution (at breast height), the relationship function between diameter and height, and the taper coefficients. The volumes of five different assortments from the stands are compared.

Since the end of the eighteenth century forest damage caused by the pathogen Gremmeniella abietina has been observed and documented. During the latest epidemic in Sweden more than 480 000 hectares forest land have been injured and this has lead to considerable economic losses. For the pathogen to succeed with infection, spore dispersal and colonization the right environmental conditions is required. The aim of this paper is to describe the diseased stands using site and stand characteristics and to evaluate the effect of these variables on the disease incidence. Further, the thinning performed during the time for spore dispersal and its relationship to injured stands is examined.

The purpose with this essay was to see how the mathematic books showed sexual roles in pictures and if they confirm or deny the traditional sexual roles that school shall counteract according to the curriculum, Lgr11. The questions I focused on were this:How sexual roles are introduced on the pictures in the chosen mathematic books?What are the similarities and differences between the presentations of the gender in the chosen education materials?I used a semiotic method to analyze my pictures. The central parts of my theories were how we think that gender is created using characteristics and attribute. In my analyze I found out that the pictures in one of the book series showed more stereotypic sexual roles than the other book series did..

Då det köptes in ny utrustning för kalibrering av värmestrålningsmätare till SP, Brandteknik, fanns det ett önskemål om att effektivisera proceduren vid kalibreringen. Vid kalibrering med den befintliga hård- och mjukvaran finns många manuella moment som skulle kunna reduceras.I detta projekt har ett styrprogram utvecklats i programmeringsspråket LabVIEW. Programmet använder ett seriellt kommunikationsprotokoll för att styra den kontroller som reglerar temperaturen i kalibreringsugnen. Programmet ställer in de temperaturnivåer som ska ingå i kalibreringen, upp till tio stycken, och kontrollerar när temperaturen har stabiliserat sig. När den gjort det tas ett antal mätpunkter ut och sparas till en resultatfil.

Electronic article surveillance (EAS) is widely used in shops and libraries together with an RF-tag attached to the goods or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have, subsequently, refrozen. In- relation to care for the elderly, one time-consuming step involves checking whether there is the necessity for a change of diaper and this can, instead, be based on an RF-tag with an EAS-system alarm. A preliminary investigation was made using the moisture sensors, which involved how the resistance changes when liquid and/or heat is applied. A simulation of the LCCR circuit (RF-tag with the sensor) was conducted in order to determine how the resonance frequency changes for different resistances levels.

Management consulting firms are dependent on attracting and recruiting new talents since the human capital has a vital role in these types of organizations. In the following years a new generation, Generation Y, will to a large extent enter the labour market. According to several studies this generation has different characteristics than older generations.This thesis examines management consulting firms? views of Generation Y and which strategies they use to attract and retain the generation. The fact that the subjects are unexplored led the authors to conduct a qualitative study of seven management consulting firms through in-depth interviews.

This diploma work on D-level is made in cooperation with Varnäsföretagen AB in Eskilstuna. The company performs contract manufactured aluminium goods. This work is a continuation on earlier diploma work in Varnäsföretagen AB. Even if the industry process consumes much energy for melting the aluminium goods, they consume a great amount of oil to warm up the building. The purpose of this work is to examine some places in the building and the process to see how much energy it is possible to recycles to the heating system and reduce the costs for heating.

During the past two decades a new expression has emerged in Swedish business linguistics: Styrelseproffs (appr. Board Professional). The aim of this paper is to study whether a board member legitimately can be considered a professional. This is investigated through the eyes of the theoretical framework of professionalization. The empirical data is collected through interviews and presents the perspective of people considered to be Board Professionals.

The purpose of the study was to investigate the use and losses of energy in an existing older building. Another purpose was also to look through various options for heating systems with renewable energy in the building. The aim was to reduce the use and losses of energy. The first step was to study the related electricity bills of the building and also perform measurements and calculations of the building envelope and ventilation. The next step was to find out the possible actions for energy saving by performing measurements and calculations.

The purpose of this study is to clarify the most important factors that affect Swedish perennial growers when designing their assortment. The study describes how herbaceous perennials are produced in Sweden today and try to give an answer to the question how growing method and choice of assortment are affecting the possibilities of Swedish producers to compete on the market. Seven perennial growers in the southern and western parts of Sweden have been interviewed about their production methods and on what basis they design the assortment of perennials. During the interviews five factors seem to be the most important when the growers choose which species to grow ? profitability, the characteristics of the species, the sales channel/customer, the growing environment/growing facility and the grower?s interest and knowledge. It is often a combination of these five factors deciding if a cultivar will be grown or not. .
