Dokumentation av en experimentell biogasanläggning
This thesis is focused on identifying and documenting all electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief technical description and information of the systems around the reactors. Furthermore there will be a brief description of LabVIEW - which is a graphical programming language- and which devices / elements are programmed. For further notification, I am not responsible for the programming of the devices in LabVIEW which I have only used as a tool in my work. The plant for production of biogas consists of four reactors of which the third reactor (Lakbädden) is connected to another reactor (UASB) where they cooperate with each other. The reactors are used for producing biogas in the form of methane gas.The reactors I and II are connected to, various electrical devices as, flow meters, temperature sensors, frequency converter and more.
Möjligheter att förutsäga kvävegödslingsbehov i höstvete med Yara N-tester
The Yara N-Tester is a handheld chlorophyll meter which can be used in several different
crops as an aid to determine if there is a need of complementary fertilization with nitrogen
(N) or not. If the crop requires more N the N-Tester will recommend an amount in kg per ha.
The possibility to assess the need of N depends on the strong relation that exists between
chlorophyll- and N-concentration in the leaves of plants. In the multiannual trial series
?Nitrogen to winter wheat at different soil conditions? measurements with the N-Tester was
carried out at flag leaf emergence (GS 37). In this work the result of measurements, the NTesters
ability to estimate the need of N in winter wheat, will be presented for the years
2008-2011.
Energiåtgång under tillverkning och produktion av byggnadskomponenter
This diploma work addresses the question of how much energy is spent whenmanufacturing the components of a building as well as of how much energy is used inthe production of a building. The object of the studies is BioCentrum at the SwedishUniversity of Agricultural Sciences in Ultuna just outside the city of Uppsala. The aimof the work was to investigate how much energy was consumed when manufacturingand production in relation to the management, how many years the production wasrepresented. It was also a study in how mature the construction industry is to answerhow much energy was consumed in manufacturing.In order to get these answers a question form was developed and sent to thesuppliers to BioCentrum. In this form they were to respond to the quantity suppliedto BioCentrum and the amount of energy was spent when manufacturing thecomponents.
Mer är bättre än mindre - En fyrdimensionell undersökning om kampanjmaterials påverkan på butiksmiljön
The purpose of this study is to investigate the effect of using more promotion material to enhance the in-store communication of sales promotion. In the retail industry today the research regarding the benefits from using various in-store promotion materials is limited, thus this study was carried out to bring clarity to this subject. The study is carried out in two pharmacies and the design of the study was to add more promotion materials to one store, while keeping the other store in its normal condition and then let the stores change conditions after one week e.g. latin-square design. The data collection of this study consists of four different methods: sales data, a questionnaire with 182 customers, an observation study of 300 consumers and an eye-tracking experiment with 41 participants.
Tree species traits response to different canopy cover for 34 tree species in an enrichment planted tropical secondary rain forest in Sabah, Malaysia
Tropical rain forests only cover around six percent of the world?s land area and contain around 70 % of the world´s animals and plants. Tropical rainforests have been, and still are, negatively affected by human activities. These activities lead to forest degradation which has negative impacts on production and biodiversity.
Between 1970-1980 forests in Borneo, Sabah, Malaysia, was subjected to intense logging.
Formulering och provning av en ny typ av sågkedjeolja
Formulation and testing of a new type of chainsaw lubricantThe company Agro Oil has come up with the idea of developing an environmentally adapted chainsaw lubricant with a new unusual base fluid. A field test with a tree-harvester shows unsatisfactory low temperature properties and high wear. In this work the viscosity, price and pour point of different combinations of the given base fluid and three other base fluids have been investigated. Desired viscosity and price are determined for different formulations. The new lubricants tested show lower pour points than almost all products on the Swedish market.A test equipment has been developed to investigate the wear.
Indirekt varumärkesutvidgning på den svenska bilmarknaden
Today automotive manufacturers are facing a crisis with increased pressure to strengthen their brands. To prevent declining results many automakers have chosen to extend its brand to other industries i.e. various forms of brand extensions. Automotive manufacturers have developed an international strategy for what merchandise to offer. The strategy has received an overall positive response, however, it does not apply well within the Swedish market where merchandise is sold in less quantity than abroad.

AbstractThe purpose of my study is to examine how preschool children experience nature and how the educationalists at the preschool can make nature more exciting and support the children?s personal growth. I have also studied what the educationalists of the preschool do and what they can do to make nature more interesting and playful for the children. Observations and interviews have been conducted at a preschool in a small town. The preschool is situated close to nature, that is, close to a small forested area.
Kromatografi av polära läkemedel och metaboliter med HILIC-teknik
The purpose of this project was to investigate if retention of polar compounds that are given to treat tuberculosis, diabetes, inflammatory bowel disease and childhood leukemia could be obtained with HILIC separation. By varying different parameters for different types of columns the compounds were analyzed with the aim of finding guidelines for future method optimizations. To perform these analyzes three different columns were tested ? ZIC-HILIC (silica-based with zwitterions), ZIC-pHILIC (polymer-based with zwitterions) and XBridge Amide (amide functions). The results were evaluated with selected quality measures.
Rörelse och språk : En kombination vid andraspråksinlärning?
I detta arbete har jag studerat rörelsens betydelse för inlärning, vilket har visat sig vara av stor vikt. Jag har dessutom studerat språk och inlärning och ur detta material framkommer att det finns mycket som spelar in vid språkinlärning, såsom motivation, ålder och härkomst. Dessa två huvudämnen, rörelse och språk, ligger till grund för min avslutande del i examensarbetet, där dessa bildar en kombination för andraspråksinlärning. Jag har funnit en metod för andraspråksinlärning som utgår från rörelseövningar. Denna metod heter TPR (Total Physical Response) och har arbetats fram av den amerikanska professorn James J Asher.

Möjligheter att utfodra överskottsmjölk till kalvar efter pastörisering
Good feeding practices are a basic aspect of good calf health. During the calf's first few months the calf is fed with purchased milk replacer or raw milk straight from the cow. On all farms, it will be a surplus of milk that may not be delivered to the dairy for various reasons. Milk that may not be supplied to the dairy includes colostrum and milk with unnormal properties, including milk from cows suffering from mastitis. This study investigated the possibility of improving the milk by pasteurization in order to secure its use as feed for calves and thereby obtain an improved calf health.

Högfrekventa tryckvariationer under de senaste århundradena
Long time-series of pressure measurements often have high quality because the early instrumentsare more or less the same as the modern ones. A time-series from Lund consisting of three dailymeasurements from 1780-1997 has been homogenised and is therefore suitable for analysingpossible influences of the enhanced greenhouse effect. According to a two-layer model of theatmosphere one finds a shift in the frequency of baroclinic instability due to an increasedtemperature gradient caused by the increasing CO2. Baroclinic instability over the Atlantic Oceanis the main cause for frontal zone production, causing cyclonic activity over the southern part ofScandinavia. Changes to the baroclinic instability would therefore be traceable in the time seriesfrom Lund.
Musik och språk i samspel på förskolan : Musik för att främja den språkliga medvetenheten hos barn i förskolan
AbstractThe purpose of this paper is to find out how the after-school teachers can work with children diagnosed with ADHD on the after-school center, study the given conditions as well as the links between the two earlier mentioned. Four interviews, with four different after-school teachers, from four after-school centers in one municipality was made. The interviews consisted of seven questions, six of the questions gave the respondents the opportunity to own interpretation of the question and thereby answer the question after what they considered as correct.The result shows that work with ADHD diagnosed children can differ widely based on the conditions the after-school teachers have. Examples of conditions are knowledge and education on the subject, the after-school center environment, the number of teachers in the business and more. Based on the four interviewed response, and the information that previous research shows about the subject, the work with ADHD diagnosed children at the four different after-schools is not good enough.
