The ammonia emissions are an environmental issue since they contribute to eutrophication. By far the largest source of ammonia emissions is manure from agriculture and should therefore be reduced. Loss of ammonia is not only negative for the environment but also to the farmer who loses nitrogen that could have been used by the crop. The focus of this study has been emissions from spreading slurry where the loss can vary widely depending on slurry-, soil-, and weather conditions. There are mainly two different ways to reduce the emissions. One is to inject or mix the slurry into the ground to avoid air contact. The other way is to use acid to reduce the pH in the slurry to a level between 5 and 6 where the equilibrium is so strongly pushed to NH4+ that hardly any NH3 can be lost.

Sahlgrenska Academyat University of GothenburgDepartment Of Internal Medicine And Clinical NutritionAbstractTitle: The effect of CLA on body weight and body fat amongst overweight and obese.Author: Sierra De Goldsmith and Amanda EgebergSupervisor: Frode SlindeExaminer: Anna WinkvistProgram: Dietician study program 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 12, 2012Background: Overweight and obesity represents a global problem as it is accompanied by an accumulation of body fat which increases the risk of developing diseases such as diabetes type 2, insulin resistance, cardio vascular diseases and certain types of cancer. Moreover, the prevalence is increasing worldwide. Many consider it difficult to reach a normal weight using only methods such as changing dietary- and exercise habits, this creating a market for products that facilitate weight loss and loss of body fat. The supplement of conjugated linoleic acid (CLA) is such a product. In animal studies, CLA has demonstrated a reduction in both body fat and weight.

Oilseed rape constitutes a good break crop within a cereal dominated cropping system. The normal sowing time for winter rape in Sweden is August. It's a time in the cropping year characterized by a heavy work load, such as harvest and soil management. In addition, it is often a period with large precipitation. Thus, it is sometimes problematic for the farmer to do the sowing of winter rape at the optimal time.

This study has focused on testing the following two hypotheses:? Pest resistant plants have higher levels and/or several different kinds of secondary metabolites. ? Induced defensive systems in resistant plants are activated more rapidly than those of susceptible plants. As a background for the test of the hypotheses a short literature study was performed concerning plant defensive mechanisms in Arabidopsis thaliana.

This literature research is meant to answer the following questions: ? What was the Swedes consumption of fat from 1935 to 2009? ? How has the fat consumption corresponded to the current recommendations? ? What is LCHF and which are the main advantages and disadvantages? Fat supplies us with energy, isolates and protect organs from bumps and punches. Fat is insoluble in water but soluble in organic solvents. The properties of a fat depend on its structure. The most common fat in human food is triacylglycerides.

The horse was domesticated about 6000 years ago. Since then humans have used the horse for different purposes, such as work force and in sports. Horses are social, group living animals that spend around 16-17 hours a day on grazing. Horses are often kept stabled in single boxes with a limited feeding time. The forage usually contains grain-based concentrates and roughage.

To provide our company a new business opportunity I have in this essay examined the economical possibilities to sell energy. I have chosen to do a case study on my own farm in this essay. The farm is focused to cropping and also have some properties for hire. The farm is situated in the village of Fjelie and that?s where the opportunity for selling heat are. Fjelie has about forty houses. The idea is to build a plant where straw is being used as fuel.

Commonly held dietary guidelines discourage full-fat dairy consumption due its to high levels of saturated fatty acids, which are believed to aversely influence cardiovascular disease risk. Cardiovascular diseases cause more than one third of deaths in the developed world. With dairy often providing a large part of energy and nutrients in Western diets, research into its effects on human health is warranted. Several recent studies have suggested a protective role of dairy in the development of cardiometabolic disease. However, many of these have used imprecise methods of dietary assessment, based on questionnaires or interviews. Biomarkers are emerging as a means of evaluating diet in a more objective way. Currently used dairy fat biomarkers are minor fatty acid constituents of dairy that preferably are unique to dairy and not influenced by endogenous metabolism.

A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.

The occurrence of small amounts of albumin in urine, microalbuminuria (MA), is used both in human- and veterinary medicine as an indicator for patients who have developing proteinuria. Proteinuria can be prerenal, renal or postrenal which is important to establish during an investigation. With conventional methods decreased renal function is not detected until 70 % of renal function is lost. The ability to detect and start a treatment earlier might reverse or slow the progression of disease. The purpose of this study was to investigate the reliability of Heska® E.R.D.-Health Screen?, a test for microalbuminuria in dogs, to detect albuminuria.

Malassezia otitis in dogs is a common cause of visit to a veterinary service. In otitis externa due to Malassezia overgrowth the dog has a higher number of yeast organisms and/or a local inflammatory response to the micro organism. Common clinical signs include pruritus, erythema, swelling and increased exudate production. Clinical symptoms and results from cytology of ear swabs from the ear canal is the mainstay for diagnosis. Any underlying condition has to be identified and corrected to avoid relapse. The treatment options for infective otitis externa are based upon topical administration of eardrops containing antibiotics, steroids and antifungals.

The purpose with this project is to compare different fuels when investing in a central combustion station at a case study farm. I have chosen to write about biofuel from an economical perspective. This because the heating costs are steadily increasing. Also because the farm in this case study has several different heating systems, which are neither profitable nor easy to work with. I have made calculations regarding usage of splinter, wood and grain for the heating system.

This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.

Det skulle även avgöras vilken av metoderna som lämpade sig bäst för detta. Ölsorter är ur Lundabryggeriets sortiment. Beska mäts i IBU som är en förkortning på ?international bitterness units? och är milligram iso-??syror per liter öl.

Probiotics is a special group of health products on the market. The most common type of  these is live cultures of lactic acid fermenting bacteria from raw milk . These include, among others, yogurt and various trademarks such as Hälsofil ®, Acidophilus ®, Dofilus ® and Kefir ®. Such products are often used by patients who are treated with antibiotics to combat the intestinal flora eliminated, thus causing digestive problems. The present work deals with yet another type of health product, viz.
