Biosensorsystem fo?r o?vervakning av vattenkvalitet

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

LCHF - Low Carb High Fat : en experimentell studie av 3 veckors LCHF-kost på hälsomarkörer hos normalviktiga kvinnor

SammanfattningSyfte och frågeställningar Syftet med denna uppsats var att undersöka hurvida en LCHF (Low Carb High Fat) kost skulle kunna vara en hälsosam livsstil utifrån hur den påverkar olika hälsomarkörer hos normalviktiga personer där en viktminskning ej har eftersträvats. Frågeställningen var följande: Hur påverkar en LCHF-kost med maximalt 30 gram kolhydrater per dag under 3 veckor normalviktiga kvinnors BMR (Basal Metabolic Rate), blodlipider, blodglukos, blodtryck, kroppssammansättning, midje- och höftmått samt deras kroppsvikt?Metod En experimentell studie har genomförts på 8 normalviktiga kvinnor mellan 20 och 35 år. Samtliga försökspersoners BMR, blodlipider, blodglukos, blodtryck, kroppssammansättning, midje- och höftmått samt kroppsvikt mättes vid normala levnadsförhållanden innan studiens start samt efter 3 veckor av en strikt LCHF-kost med endast 30 gram kolhydrater per dag.Resultat BMR sänktes i genomsnitt med 4,4% vilket var signifikant (P<0,05). HDL (High-density lipoproteins), LDL (Low-density lipoproteins) samt totalkolesterol höjdes signifikant (P<0,01) med 21%, 25% respektive 22%.

Effects of palmitic and stearic acids supplementation on milk yield, composition and milk lipolysis in dairy cows

When facing the fact that high yielding dairy cows has an increasing energy requirements, the practice of adding lipid supplements such as concentrates rich in palm oil and/or palm oil industry by-products become more common. Palm oil containing high levels of C16:0 causes high levels of free fatty acids (FFA) which are linked to larger milk fat globules (MFG) which affect the reaction of lipolysis resulting in rancid flavour and processing problems. Instead of using palm oil, rapeseed oil rich in C18:1 C18:2 can be used. In order to evaluate the effect of added C18:0 and C16:0 on milk lipolysis, 30 Swedish Red lactating dairy cows including 15 multiparous (MP) and 15 primiparous (PP) cows were randomly divided in three groups resulting in 3 10 cow-groups (5 PP and 5 MP cows per group) and fed one out of three concentrate mixtures: control (C), a standard concentrate mixture with no fat added; palmitate (P) as C plus the addition of palmitate methyl ester (10 % in DM basis); and stearate (St) as C plus the addition of stearate methyl ester (10 % in DM basis). Milk yield was registered, and milk samples were collected and analysed for milk composition, FFA content and size of MFG.

Recipientundersökning av Ensjön : Bedömning av sulfidmalmgruvan Enåsens eventuella påverkan på sjöns vattenkvalitet

Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.

Optimering av informationsinsamlingvid prototyptillverkning

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

Att förstå medborgardialoger från olika perspektiv

The aim of this study was to describe and analyze the problems caused by students that characterize themselves as highly sensitive. The issue of high sensitivity and other categorizations are fiercely debated in the research. This empirical study was conducted in light of literature about high sensitivity, pedagogies, and interview methods. The students answered questions about what makes them categorize themselves and how they believe that the categorization affects their learning and social development. They also responded to questions about what they consider appropriate measures to improve their situation.

Vuxnas läsning av ungdomslitteratur ? en påse med godis, en trettioårskris eller som vilken litteratur som helst?

I approach the subject of adult readers of young adult fiction through an analytical framework influenced by Cultural Studies, implicating that young adult fiction is caught up in a system of distinction between popular literature and high literature. I contrast this with theories that suggest that there has been a loosening of this hierarchy and that they now coexist, even borrowing features from one another. I also examine questions of ideology, namely the ideology of mass culture, the ironical attitude and the ideology of populism. I also use Andreas Huyssen?s theory of mass culture as a woman, seeing as popular literature often tends to be categorized with feminine traits.

Analys av energiförbrukning, Akzo Nobel Functional Chemicals AB

The main purpose of this project was to make a survey of the steam and electricity consumption at Akzo Nobel Functional Chemistry AB and give suggestions of how to minimize them. These three different areas were focused on. First to make a survey of all the most important consumers, second to find the electricity consumption of the air compressors and the amount of waste heat produced from them. The third area was to calculate a model of how much fresh water that is used during a cooling sequence in the water based heating/cooling system of the reactors and give a suggestion of a suitable reuse for this water.The main result is a total survey of the energy consumption in steam and electricity. The survey shows that the second largest group after drying is heating of ventilation which gives big potentials of reducing the total steam consumption if there is a way of being self supporting in ventilation heat.

Lönsamhetsanalys av tekniker för utökad elproduktion i kraftvärme : Med hänsyn till elprisets variationer

This thesis aims to examine the viability of various techniques for increased electricity generation in CHP plants and the effect of electricity price fluctuations on the profitability.The techniques examined are fuel dryer, pellet production, methane production, combined methane- and pellet production, seasonal heating storages in caverns and pit heat storages and condensing tail. Using Excel and Matlab, the prerequisites for investment costs, revenues and expenses were calculated.What affects the price of electricity is a combination of economic and technological development, energy prices, economic structure, population changes and weather. Different scenarios for the electricity price were therefore examined. In the base case, the electricity price was given by the Nord Pool electricity price statistics of area three in 2011. Thereafter, WiMo was used to design the electricity scenarios for 2030, which was then applied to the data to obtain the viability of various scenarios. The techniques examined were found to give greater profits to the CHP plant by increasing and optimizing the production of electricity.

Att fråga eller inte fråga, det är frågan : En studie av frågor mellan lärare och elever under kemilektioner

This report presents the use of questions by both teachers and students in chemistry class. Both students and teachers have been observed during 24 lessons, both theoretical and practical. In addition, interviews have been made with the teachers and the students have answered a questionnaire. The result show that a high number of questions are asked, more than one per minute and that both teachers and students ask the same amount of questions. This contradicts earlier findings were teachers questions dominate.
