Optimization of soil tillage and crop rotation is important in many aspects, but particularly in maximizing profit margins. Since the economic outcome is usually decisive, it can be interesting to study different combinations of soil tillage systems and crop rotations in order to identify the maximum economic outcome. How a crop functions in a particular tillage system determines whether it is profitable to grow that crop. Different tillage systems affect the soil and its processes in different ways. Reduced tillage often works best on weak-structured heavy clays and on silty clays.

Compared with a few years ago, the cost of concentrates has increased substantially and because of that an increased proportion of pasture is of interest. Pasture is cheap and the farmer does not have to harvest when the cows do it themselves by grazing. This saves both money and time. According to research milk yield decrease with an increasing proportion of pasture in the diet. This is because cows on pasture will have lower dry matter intake than cows with supplements.

Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

This is a study made because I would like to see how much money can be saved when reduced soil preparations is used. This is a case study, the farm is located in the north vest part of Skåne, Sweden. I have calculated with four different soilpreparation methods. Alternative 1: Conventional soil preparation, the way the farm is managed today. Alternative 2: Ploughing on depth of 12 centimeters, with a ridge packer followed with sowing. Alternative 3: Eco-tillage Alternative 4: Direct drilling The results of my study showes that Alternative 2 is the most profitable. Alternative 4 is very good if you see to dieselexpenses and hours of work, but the yield is far to low. If the numbers are further analized, it showes that in spring barley the differense between Alternative 2 and Alternative 4 is at a minimum. So if there is lack of time for one reason or another, this might be an alternative in spring barley. The differense in how the farm is managed today and the most profitable alternative in the study, Alternative 2 showes that it can be saved up to 60 940 SEK..

Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.

Gothic literature has a tradition of dealing with dark subjects, themes and motifs, as well as depicting fear in different shapes and forms. Dani Cavallaro describes dark fiction in terms of the "aesthetic of the unwelcome". The philosopher Edmund Burke separates the beautiful from the sublime and writes that everything that is capable of producing a terror of pain and death is a source of the sublime. In her essay "On the Supernatural in Poetry", Ann Radcliffe draws a clear line between the concepts of terror and horror and distinguished them as fundamentally different. In this essay, I define the terms horror and terror by following up the research surrounding Radcliffes statement.

The prime aim of this thesis was to investigate whether high or low iodine intake during certain periods of life was, or was not a strong risk factor for the development of canine lymphocytic thyroiditis (CLT). And secondly, if a high or low selenium intake in a combination with high or low iodine intake also may have an influence on that risk factor. To investigate this, a dietary questionnaire was sent out to dog owners. The dogs were selected from an ongoing genetic study of CLT. The questions investigated brand and type of feed during different life stages (puppy, junior and adult) and also if there were any use of dietary supplements.

Detta examensarbete är utfört vid brytarenheten i Ludvika, den del av ABB Power Technologies High Voltage Products som utvecklar, tillverkar och säljer högspänningsbrytare. Brytare är en av de ingående delarna i ett ställverk och har till uppgift att bryta respektive sluta spänningen i ett kraftnät. Eftersom brytarna placeras ute i samhällen och vid olycka skulle orsaka stora skador är det viktigt att arbeta med kvalitet. Detta sker genom att alla producerade brytares funktion säkerställs med hjälp av en rutinprovning före leverans till kund. Syftet med examensarbetet är att genomföra ett förbättringsprojekt för att identifiera faktorer som påverkar brytarenhetens First Pass Yield, ett mätetal i rutinprovningen.

This paper studies the research foundations created in 1994 from the former wage earners? funds out of a portfolio management point of view. Firstly it describes the seven largest foundations and their different portfolio management structures. Secondly it analyses the performance of these foundations measured as the intercept, Jensen?s a, in a linear regression of the excess returns of a portfolio versus a proxy for the market, as well as the Sharpe-ratio.

Recently, retailers within the Swedish grocery retail sector have launched lines of products under its own brand, quite often produced by manufactures within the same category of products. The common term of this phenomenon is called private labels. Therefore, private labels could be seen as competitors against branded goods, despite the fact that it is, in several cases, the same manufacturer who produces each of the products.The main purpose of this study is to provide understanding of how the manufacturers choose to position themselves, formulate their strategies and compete on the market among private labels, also to examine the motive behind the manufacturer's choice to produce private labels. The study intends to provide a broader view of how the interaction between manufacturers, retailers, private labels and branded goods appears on the Swedish market. We decided to use a qualitative research method and personal interviews to approach the study.

Under de senaste åren har sågverksindustrin påverkats starkt av det som närmast beskrivs som en finanskris. De rådande förhållandena ställer höga krav på sågverksföretagen och för överlevnad krävs ekonomisk uthållighet, effektiv produktion och hög grad av kostnadsmedvetenhet. AB Karl Hedin har haft en positiv utveckling, men som många andra företag i sågverksbranschen arbetar AB Karl Hedin ständigt mot effektivare produktion och ökad lönsamhet. En faktor för ökad lönsamhet kan vara förbättrat råvaruutnyttjande. Efter en lång tid med högt marknadsfokus ser därför AB Karl Hedin i Krylbo ett behov av att öka fokus på förbättrat sågutbyte.

BIOGAS POTENTIAL IN GRASSES FROM WETLANDSMarvin MartinsThe purpose of this study has been to survey wetlands that are suitable for mowing and to analyze the biogas potential in the harvested grasses. A preformed investigation showed that there are suitable wetlands, which can be harvestable, namely those mowed formerly in traditional haymaking. The practice of traditional haymaking is dying out in Sweden today but there are several good reasons why it should to be reconsidered. Nature- and cultural values are obvious, also the unutilized energy in the grass.The suitable types of wetland that were specifically studied were the productive wetlands; meadow marshes and wet meadows. These wetlands are represented in the Swedish meadow- and pasture inventory database; (TUVA) and the Swedish national wetland inventory (VMI).

Concrete is one of the world?s most common construction materials and is composed of 70-80 % stone material. Today crushed stone is used as aggregate in concrete in order to replace natural aggregates due to strong environmental reasons. Stone crushing yields flaky material and in this thesis studies are made on the flaky particle shape and how it influence properties of concrete such as workability, rheology and strength. The concrete recipes used in this thesis have fixed values, the only variable is the flakiness of the crushed stone.

At the Division of Electricity at UppsalaUniversitythere are ongoing researches, including a research concerning turbo generators.Turbo generators produce a large share of electricity in the world; however they are costly mainly due to the fact that the cooling and ventilation that are needed to eliminate the excess heat from the generators are expensive. Turbo generators work with high efficiency and in this project, the main task is to simulate a generator while taking into account that the generator must be designed against self-oscillation, centrifugal force, exhaustion and heat. The turbo generator must be simulated without being too expensive and complicated.In this project, the dimensions of the turbo generator depend on the efficiency of it, and where the losses are in the generator. Furthermore, the optimum values need to be chosen with the help of the ACE simulation program. The report begins with an introduction describing the project followed by a task description that is dealing with the project.

To meet the needs and demands of the costumer, accurate information about how much is available in stock is necessary. When the information in the system does not match the physical inventory, inventory inaccuracy occurs. Inventory inaccuracy is common among companies and may contribute to increased labor cost, excess inventory, production disruptions, waste of time, late deliveries, poor service and lost customers.The purpose of this study is to identify contributing factors to inventory inaccuracy for business with outdoor storage. The study also aims to investigate how efficiency factors can reduce the inventory inaccuracy for business with outdoor storage.A case study was conducted to answer the purpose. A company in the steel industry was chosen to examine inventory inaccuracy on business with outdoor storage.
