In order to facilitate testing of anesthesia machines a patient simulator has been required by Maquet Critical Care AB. A patient simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient simulator has fulfilled the requirements.

Today?s farmers are constantly affected by the fluctuating world market prices on grain and thereby the price risk that comes with the price fluctuations. The volatile prices of grain increase the price risk within the business, which in turn affects the profitability of the business. The fluctuating prices together with the increased price risk within the farm business have opened up the market for hedging instruments. In this master thesis project, the aim is to identify the underlying end-values of 30 Swedish farmers? related to their choice of using hedging and the product; forward contract.

Since the financial crisis of 2007, the global financial market has been characterized by instability. At the same time the banks? lending rates and its link to the reporänta have been in the spotlight in various debates in the media. The government with Anders Borg leading the charge has criticized the banks for not lowering their lending rates when the reporänta has been lowered. The banks defend themselves by saying that the reporänta does not have a direct link to their lending rates anymore.

The demands for higher production yields and better quality materials from the forests are increasing globally. Tree breeding programs are directed to meet the future demands on forests. In order to capture the full benefits from the breeding programs, clonal propagation is necessary. For most conifer species, somatic embryogenesis (SE) is the only available option for large scale clonal propagation of Elite clonal material. For Norway spruce (Picea abies L.

Denna rapport är en studie där tre olika reningstekniker för att reducera utsläppen av VOC, (volatile organic compounds) på färgföretaget Beckers Group, jämförs och utvärderas. De reduceringsmetoder Beckers använder sig av i dagsläget vilka ska jämföras är på anläggningen i Sverige en uppkoncentrering med en zeolitrotor följt av katalytisk förbränning. Anläggningarna i Kina har ett skrubbertorn med diesel följt av en aktiv kolbädd som polersteg. Anläggningarna i USA har en katalytisk förbränningsmetod kallad Oxidizer.Teknikerna jämförs och utvärderas utifrån teknik, miljö och ekonomi i rapporten. Rapporten inleds med att teori gällande färgtillverkning, lösningsmedel och reningsteknikerna redogörs.

The purpose with this literature study was to investigate the possibilities for improvement of forage protein in dairy cows with focus on feeding strategies and conservation of forage protein. The utilization of forage protein in dairy cows is often not that efficient as it could be. The feed crude protein consists of both true proteins and non protein nitrogen. The digestion of proteins in the rumen depends on the protein degradation rate and the ability of the microbes to synthesize microbial protein. The microbes need a balance between carbohydrates that provide them with energy and proteins that are degradable in the rumen.

Syfte: Syftet ?r att unders?ka om intag av m?ttat och flerom?ttat fett har olika effekt p? postprandiell inflammation, hos friska vuxna i ?ldrarna 18-70 ?r. Metod: F?r att genomf?ra denna systematiska ?versiktsartikel utf?rdes litteraturs?kningar i databaserna PubMed och Scopus. Specifika s?kblock skapades f?r varje databas f?r att identifiera vetenskapliga artiklar g?llande postprandiell inflammation efter intag av m?ttat eller flerom?ttat fett. Nyckelord som anv?ndes i s?kningen inkluderade ?fatty acid?, ?inflammation? och "postprandial". Titlar och abstrakt av de h?mtade artiklarna granskades f?r att bed?ma deras relevans f?r studiens syfte.

Brominated flame retardants (BFRs) has for many years been used in products to reduce their flammability, mainly in electronic products, textiles and construction materials. In 2003, Sweden imported 300 tons of brominated flame retardants. Leakage of these compounds has polluted natural environments. Fishes has shown increased contents of these substances, especially fat fish, since brominated flame retardants tends to accumulate in fatty tissues. They are also regarded as persistent and that gives them the ability to travel long distances. What also is really scary is that increased levels of brominated flame retardants have been detected in human breast milk. The knowledge of the brominated flame retardants is limited and not so much research has been done in this field. There are many reasons though, to keep the research going. Partly their structural resemblance to well-known toxics as PCB, but also their ability to accumulate in biological systems and enrich in food chains. In which way they affect humans we really don?t know yet.

The world?s growing need for energy together with a desire to ward off the worst consequences of global climate change has resulted in a never seen desire to invest resources in renewable energy sources. Biogas production through anaerobic digestion is one of those growing energy sources. In Sweden there are over two hundred plants that uses this biological process to break down organic substances while producing carbon dioxide and the energy-rich gas methane.This master?s thesis has focused on development of the mixture of different organic substances that is treated at a specific plant, namely Mosserud biogas plant.

Abstract Cavities used to be a very common problem but over time humans have learned to take care of their teeth. However, there are still many who have problems. This problem is due to microorganisms and in particular the various streptococci and lactobacilli producing acids which loosens up the enamel on teeth. These bacteria can be found at various places in the mouth and saliva. Besides being a discomfort it can be a major problems and the damaged tooth needs to be removed or make a dental filling. The aim of the study was to see how intake of probiotic tablets containing Lactobacillus reuteri PTA ATCC 5289 and Lactobacillus reuteri DSM 17938 affects the levels of oral Streptococcus mutans and lactobacilli over a three-week period.

The purpose of this study was to evaluate which apple cultivars are best suited for production of juice and cider. The study was limited to 41 cultivars. Common as well as uncommon apple cultivars were selected from available cultivars in the cold storage at Balsgård, Department of Horticultural Plant Breeding and Biotechnology, SLU.The practical part of the study consisted of the apples being pressed, and then the juice characteristics being assessed by appropriate criteria and methods of analysis. The analyses consisted of measurment of soluble sugars with a refractometer (Brix), titration of total acidity, determination of total phenolic content with a spectrophotometer, estimation of alcohol content by density meters and qualitative taste tests.The study did not account for different maturity of cultivars. Different apple cultivars were pressed on separate occasions, before and after Christmas 2010.

In organic animal production, synthetic amino acids are not allowed. Therefore, a higher level of crude protein is needed in the diet to pigs, which lead to more nitrogen (N) excreted in the faeces and urine. N can be emitted to the air in the form of e.g. ammonia (NH3), which contributes to eutrophication and acidification and as nitrous oxide (N2O), which is a very potent greenhouse gas. The emission of N can be reduced by e.g.

It is possible to affect the feed costs in different ways. By steeping or fermentation the digestibility of the feed is improved for the animals with a natural process in the wet feeding system Steeping means that the feed is soaked some hours before feeding. This process activatesenzymes and improves the digestibility of for example phosphorus in the feed and make it more accessible to the animal. Wet feeding can be fermented or not. Fermentationmeans that the feed has been soaked for a certain length of time so that a biological process is started.
