The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

The number of weaned piglets per sow and year is a good measurement of sow productivity since it is affected by the number of piglets born alive, the pre weaning mortality (i.e. mortality of live born piglets between birth and weaning) and the number of litters per sow and year. This measure is also closely connected to the number of piglets produced per year, which partly determines the profitability of the piglet producer. During this study, eleven successful piglet-producing herds were visited. Eight of the producers were Swedish and three of the producers were Danish.

Half of Sweden?s 140 000-150 000 sows are culled and replaced by 75 000 gilts annually. Culling of old sows is necessary and allows new breeding material to enter the herd. However, many of the culled sows are young, and have not yet become profitable at the time for culling. Therefore, it is an important question for the pig industry, how to raise gilts to sows with a high and sustainable production level.

The elevated level of testosterone often leads to problem with acne and hirsutism, and it is also common with overweight and metabolic syndrome. The nutrition treatment has mainly consisted of energy restriction, together with exercise and drugs to reduce insulin resistance and consequently reduce androgen levels. However, an in-depth knowledge about how the components of our diet can affect further, is lacking.Omega-3-fatty acids can affect insulin resistance and testosterone levels within other groups but today knowledge is lacking if these findings can be transferred to women with PCOS.

Theconditions lead to morbidity and lowered quality of life. Since there is research showing aconnection between obesity and low levels of serum 25(OH)D, this raises the question ifsupplementation of vitamin D may have positive effects on body weight, waist circumference andbody composition in the overweight and obese.Objective: To investigate if there is enough scientific evidence to recommend vitamin Dsupplementation combined with nutrition therapy to overweight and obese patients.Search strategy: The systematic collection of data was performed in the databases PubMed andScopus. Search terms included were ?vitamin D supplementation?, ?obesity? ?cohort?, ?vitamin D?,?vitamin D3 supplementation? and ?overweight?.Selection criteria: Human studies with RCT, CCT or cohort design written in English orSwedish were included.

Stem rust, Puccinia graminis, has caused enormous yield losses throughout history which have had significant consequences for oat and wheat production. Today in Sweden stem rust is only reported from rye, oats and wild grasses. Stem rust infections in wheat have become unusual due to the general use of resistant wheat varieties and also due to the eradication of barberry, Berberis vulgaris, the alternate host for P. graminis. According to international sources, new races of P.

Bakgrund: Mat till svaga och sjuka äldre är en viktig del av den medicinska behandlingen. Äldre individer drabbas ofta av viktförlust på grund av ät svårigheter vilket kan leda till undernäring, det främsta nutritionsproblemet i Sverige. Matservicen är en viktig del inom äldreomsorgen. Det kommer nya metoder för att denna service ska kunna producera stora mängder av mat på ett praktiskt sätt, med tanke på ekonomi och resurser. Men även med tanke på matsäkerhet, sensoriskt perspektiv och nutritionsegenskaper.

Subclinical mastitis (SCM) is a well-known problem in the dairy sector, where it causes severe economic losses mainly due to reduced milk production. This is a problem not only in the western world but also in developing countries. Surveys from different developing countries have shown a SCM prevalence of 52.4 ? 88.6 % at cow level and 26.7 ? 63.2 % at quarter-level. To combat mastitis is important to optimize the milk production of the cow.

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Negativ energibalans och fysisk aktivitet resulterar ba?da i ett skifte i energianva?ndningen i kroppen. Vid nega- tiv energibalans delas detta skifte in i tre faser da?r den fo?rsta fasen karakta?riseras av en o?kad glukoneogenes, lipolys och ketogenes; den andra fasen av en acceleration av dessa processer; och den tredje fasen av en ha?m- ning av glukoneogenesen. Vid fysisk aktivitet pa?verkas energiomsa?ttningen av intensiteten och varaktigheten pa? den fysiska aktiviteten, da?r en ho?g intensitet gynnar glykogennedbrytningen och en la?gre intensitet o?kar anva?ndningen av fett som energika?lla.

The most suitable method to answer the issues of this study was to do a combined literature- and questionnaire study. The literature part of the study was based on Original Research articles, Review Articles and books with a list of reference literature after each chapter and the purpose was to answer the questions ?What feed items should be given to rabbits in different life stages? and ?Which problems may develop from an inadequate diet?? Two questionnaires were constructed. One was sent by e-mail to small animal veterinary hospitals to be answered anonymously by veterinary nurses. The other was linked to from two internet forums, that with rabbits as their focus.

BakgrundIntresset för verksamhetsstyrning har ökat de senaste åren och ständigt har det uppkommit nya verktyg för att förbättra den befintliga styrningen. Business Activity Monitoring (BAM) kom in på marknaden för tre till fyra år sedan för att möta de växande kraven. BAM tillhandahåller enkelt utryckt mätning av ett företags aktiviteter med syfte att förbättra styrningen av verksamhetens operationer samt ge stöd för beslutsfattande. BAM är en relativt ny företeelse inom systemstöd och i Sverige är det endast ett fåtal företag som har implementerat tekniken.ProblemDå det ständigt uppkommer nya system för styrning på markanden kan det ibland vara svårt att förstå vad som skiljer dem åt. Leverantörer av BAM utger sig för att tillhandahålla en lösning till styrningsrelaterade problem, frågan är om företag i verkligheten har dessa problem och vill få dem lösta.SyfteSyftet är att beskriva hur styrningen ser ut i 10 tillverkningsföretag i Sverige, med syfte att identifiera medvetenhet, användning, intresse samt behov av BAM.MetodDå det finns begränsad forskning och teoribildning gällande BAM har uppsatsen en explorativ karaktär.
