To produce milk of good standard the feed for the animals kept for milk production is an important part in the work of quality. This makes it important to feed them with good forage, especially when feeding with silage. The process of making silage is very complex and requires a careful handling to be successful. The fundamental idea is to create an anaerobic environment in the herbage to favour the desirable micro-organisms, in this case the lactic acid bacteria. This environment is created by careful handlings were the importance is to pack the crop well and cover it as soon as possible to exclude oxygen.

Daily citizens are informed by the media about the environment and the climate changes. The schools purpose is to educate students according to events that are of current interest and take place in present time. According to Swedish curriculum, Lpf94, all Swedish education should include and discuss the problems surrounding durable development. The purpose of the study is to se how the textbooks in History, Social studies and Geography and their contents meet the demands of the curriculum. The study shows that only the textbooks in geography meets the demands that the curriculums have on durable development.

Gamification är en strategi som använder spelmekanismer och spelkomponenter för att skapa motivation och engagemang hos användare av olika typer av system. Denna studie syftar till att undersöka om gamification kan användas för att motivera användare av system för tillverkningsindustrin.Studien har genomförts med en initial litteraturstudie och kvalitativa intervjuer med experter inom gamification samt utveckling av system för tillverkningsindustrin. Intervjufrågor har därefter ställts mot tidigare genomförd forskning, för att identifiera möjliga resultat.Resultatet av denna studie visar att spelmekanismer och spelkomponenter skulle kunna användas i ett system för tillverkningsindustrin, förutsatt att det finns ett tydligt affärsmål, mätbar och användbar data samt identifierade drivkrafter hos organisationens maskinoperatörer. Vidare har ett antal punkter identifierats som kan vara motiverande för en användare av system för tillverkningsindustrin:Möjlighet för operatörerna att följa utvecklingen i sitt expertområdeKartläggning av operatörernas drivkrafter, vilken därefter används för att förbättra operatörernas arbetssituation, med exempelvis mer givande uppgifterBelöningar som utdelas är matchade mot operatörernas preferenser, med syfte att vara mer effektiva som motivationsskapare.

Large quantities of chemicals are used in all areas of society. The chemicals can be toxic and dangerous for the environment if used incorrectly. To protect people and the environment from dangerous chemicals, a good control of them and an active work to phase out hazardous substances in all areas where chemicals are present, are needed. Banverket and Vägverket handle in production a wide range of chemical products. Many of the products are dangerous to the environment, for those who work with them and to others who may come into contact with them.

Scania Top Team is a competition where the best mechanics in the world are competing against each other. In 2011, the world final was recorded and this material is now used to see which problem solving strategies these top of the line teams are using to solve the realistic problems assembled in front of them. To help them, the mechanics are allowed to use two of Scanias IT-systems: Scania Multi and Scania Diagnose and Programmer 3. This report consists of two parts. The first part is the development of a method to analyze the recorded material.

This report describes a master thesis performed at Saab in Arboga. The main purpose was to build a controller for a system containing a turn table and an antenna beam. The idea is to use this system on a boat where it will be exposed to position disturbances due to waves. The desired behaviour is that antennas placed on the antenna beam should point towards the same target all the time. To solve this problem the system has been modeled and simulated in Matlab and Simulink.

Turismaktiviteter till havs har kommit att få ett ökat intresse de senaste åren, där människor har upptäckt fördelen med kryssningsfärjor som transportmedel. De erbjuder ett varierat utbud av aktiviteter och upplevelser ombord, som både privat- och affärsresenärer kan ta del av. Detta omfattar flera kundgrupper med olika behov, vilket innebär att rederierna måste uppfylla kundernas förväntningar och vad de efterfrågar. I nuläget finns det en bred konkurrens på marknaden, där de olika aktörerna försöker skapa en egen nisch genom olika marknadsföringsstrategier i syfte att skapa långsiktiga relationer.Syftet med vår studie är att utreda hur Stockholms tre största rederier, Tallink Silja AB, Viking Line AB och Birka Cruises AB, arbetar för att behålla och vårda sina befintliga resenärer, samt vilka strategier som används för att nå nya kundsegment. Vi har även utgått ifrån kundens perspektiv för att undersöka hur de förhåller sig till företagens produkter och tjänster.

A system for sampling of alcohol and aldehyde from diluted exhaust gases from vehicles powered by ethanol has been developed and tested. The major part of the work has been research of earlier work in the field and the construction of the sampling system.The part of the system constructed for the measurement of alcohol has been shown to work, however, more test should be performed. The part of the system constructed for the measurement of aldehyde was tested parallel to a commercially available system, based on the same principle of measurement, and has been shown to work well.Determination of the concentration of gaseous ethanol using a FID has shown the since earlier known fact that a FID is not able to measure a correct concentration of ethanol. Furthermore it has been shown that high concentrations of gaseous ethanol can not be kept in a bag more than a few minutes without a substantial decrease of the measured concentration..

An environmental review has been carried out at FORIA AB, a transportation- and machine service company, to analyze the company?s environmental aspects from the transportation segment. This report describes the essential background and the methods of identifying and evaluate the environmental aspects. It also describes how the work with the environmental aspects often vary between different actors. The design of the ISO 14001 is intentionally broad in order to apply on all sorts of activities and organizations.

The purpose of this thesis is to examine how teachers work and reflects on gender education in preschools. We also want to take part of how teacher?s thoughts are reflected in the physical indoor environment and how the environment is designed by reviewing the rooms furnishing and the selected materials. We will do this by visiting a number of preschools located in Stockholm and New York. We have chosen three questions to get the answers on our purpose.How teachers reflect around gender pedagogy are, and how the thoughts are expressed in the practical work.How the teachers communicate with their co-workers about gender pedagogy.How the teachers own thoughts and reflections on gender pedagogy have been expressed in the physical indoor environment where the children stay during the day. We have used interviews and observations as a method to gather the information that we needed to answer our questions of the thesis.

The purpose of this analysis was by qualitative semi-structured interviews with twelve children 5-years old and six pre-school teachers at three pre-schools, a total of six departments, find out how pre-school teachers worked with waste separation, if it motivated the children to take care of the environment, and if the work was understandable for the children. The results showed that the children did not comprehend what the pre-school teachers expressed that they worked with regarding waste separation and actions connected to caring for the environment. The pre-school teachers also expressed that the children was not mature enough to learn about the process when waste separated garbage is recycled, and that the work with the subject therefore had been carried out on a lower level. The children however expressed knowledge that did not come straight from their actual every day life, but since dialogue about the subject did not seem to exist between pre-school teachers and children, the pre-school teachers appeared to have failed in making the learning meaningful and understandable for the children, from their knowledge, experiences and interests..

Metabolic diseases in dairy cows are considered to increase the risk for claw lesions, most of all laminitis, sole haemorrhages and sole ulcers, but also to increase the risk for environmental claw lesions. The aim of this study was to compare claw health in 27 Swedish dairy farms, 18 with high incidence of metabolic diseases and 9 with low incidence. Data on claw health status was retrieved from recordings at routine claw trimmings and analysed on herd level regarding the prevalence of: any lesion, interdigital dermatitis, heel-horn erosion, sole haemorrhages, sole ulcer, lameness, abnormal claw shape, and other diseases (abscess in the white line, limb disorders, double sole, laminitic groove, white line disease, interdigital phlegmon, interdigital hyperplasia, toe abscess and verucose dermatitis). Mean prevalence of any lesion for herds with low incidence of metabolic diseases was 48 % and in herds with high incidence 41 %, and there was no statistical difference between the two groups. Mean prevalence for interdigital dermatitis was 2,0 % and 6.4 % in the low and high incidence groups, respectively (p.

A cars powertrain consists of everything that is needed for its propulsion. The components in the driveline that transfer the power from the engine to the driven wheels are not absolutely stiff, hence they will wind up due to the torque and act as torsion springs. If you suddenly demand a bigger torque by stepping on the accelerator pedal, a so called tip in manoeuvre, and that torque is acquired from the engine as quickly as possible, the driveline will not be able to transfer that fast torque change due to its weakness and as a result it will start to oscillate. These oscillations will be transferred to the driven wheels and make the car to accelerate jerkily which will be experienced as uncomfortable by the passengers. Furthermore, there is a backlash in the driveline that will make the weakness in the driveline even more excited than it should have been if the backlash did not existed.To avoid too big problems with these oscillations there is a control system that controls the demanded torque.

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

One of our big public health problems in Sweden is that human beings are too inactive in outdoor settings. That is why stress related diseases increase and influence humans both mentally and physical. The physical activity is halved among many children when they start school and the older they become the less they enjoy school. It is also an increasing problem that children and youth in today's society have lack of worthwhile experiences in the nature. The aim of this study was therefore to examine how the experience of outdoor environment had importance for health and learning on upper secondary school pupils.
