In order to produce grain in an economically rational manner numerous decisions have to be made. One of these decisions is what tillage system to use. The cost of the tillage system is a large part of the total cost in grain production. Different tillage systems result in different distribution of fixed costs, operating costs and timeliness costs. The price of the produced grain and cost of inputs also affect the best way to produce grain.

Studies show that some pupils with ASD (autism spectrum disorder) can have difficulties in understanding written texts. The present study seeks to examine whether pupils with ASD differ in their reading comprehension of a factual text and a literary text. Another aim of the study is to obtain a picture of the reading habits of high school pupils with ASD, what reading strategies they use, and how they work with texts in Swedish lessons in school.The study uses texts from PISA surveys from 2009 and 2000. The factual text Varmluftsballongen (The Hot-air Balloon) was taken from the try-out for the 2009 survey and the literary text Gåvan (The Gift) was taken from the 2000 PISA survey. To gain some idea of the pupils? reading comprehension of the texts, the present study used the tasks accompanying the texts, with certain changes in the questions about the text on the hot-air balloon.

Inledning: Stockholm står idag inför en breddning av hotellutbudet, hur förhåller sig hotellen till den ökande konkurrensen? Kommer hotellen att förändra prisstrategierna och kan eventuella prisförändringar leda till ett priskrig?Syfte: Syftet med studien var att titta på hur olika hotell skiljer sig i prissättning och få insikt kring priskrig och om det kommer uppstå då konkurrensen ökar.Metod: Enkätstudie med viss kvalitativ metodundersökning har använts, på grund av flexibel och hanterbar data som svarar på syfte och frågeställning. Teoretisk data har inhämtats från artiklar och publicerade böcker. Det har även använts artiklar för att påvisa ämnets aktualitet. Tio Revenue Managers (RM) har intervjuats.

The large-scale soy cultivation has negative consequences for the habitat of local populations because of the intensive use of pesticides and the destruction of rain forests and eco-systems. GM soya, varieties are often used. The majority of Swedish people, however, do not want GM products in their food. It will be hard in future to ensure GM free food, particularly foods that come from countries where GM crops are grown on a large scale. It is very difficult to avoid cross- contamination when both GM and non-GM crops are grown in the same area.

In the fluidized bed furnace at Rönnskärsverken, Skelleftehamn, sulphur-containing ore concentrates are roasted in order to remove about 50% of the sulphur in the incoming ore concentrate. This occurs in order to reach the goal of a matte containing 55% of copper in the following smelting process. At the same time as the ore concentrate is partially roasted pollutions as arsenic, antimony and bismuth are expelled. Earlier made thermodynamic calculations of equilibrium suggested that calcium and magnesium form stable compounds with arsenic and thereby inhibit expellation of arsenic in the fluidized bed furnace, an element that is undesired. The purpose of this thesis work was to gain knowledge of the mechanisms behind the formation of these stable arsenic compounds.

To produce fine fibre wool as a complement to lamb meat production, Merino and Svea sheep are currently being crossbred in the county of Jämtland. The aim of this study was to evaluate growth and wool quality of the first crossbred lambs. In addition, a literature study about nutritional effects on wool production has been carried out. The literature study showed that fine fibre wool should foremost be achieved through directed breeding. Nutritional requirements of the sheep at different stages of production should determine their feeding.

To get a good economy on the dairy farms the fertility control of heifers and cows is a crucial factor. It is also important to know which key parameters that should be tracked. In this work well established routines for heat detection have to be applied. When the dairy farmers use technical aid in estrus control it is important not to forget that technical aids can not replace the human eye. Approximately 50 % of all opportunities to inseminate are missed because clear signs of estrus have not been displayed and/or recorded. The cattle fertility has been declining over recent years. During the same time the cow?s proceeds have increased, consequently applying a higher pressure on the cow and the manager.

Investment aid is a part of the Rural Area Programme, which contains support to Swedish agriculture and the countryside. There is a new programme every seventh year and SLU (Swedish University of Agriculture) has the mission to perform the evaluation of the previous programme, which lasted between 2000 -2006. The investment aid's aim is to support investments that, among other things, support the adaptation or conversion to more environmentally friendly production methods, improves the product quality, develops new or complementing activities, and improves the environment and the animal- and working environment. The question is if it's only money that matters for these kinds of investments to be done and what has happened with the money that was paid? This thesis investigates how the investment aid has affected the receivers.

Product development is a risky business; many products never yield profit, but it is also ne-cessary for a company?s survival in a competitive business where the costumers change their requests constantly. Consumer-led product development is developed from the wish to fill the consumer?s needs and expectations and thereby be more likely to succeed. Lindell?s Gårdsslakteri AB is a local slaughter and meat processor in Västergötland.

This dissertation aims to explore how an investment appraisal differs depending on if it is conducted by a municipal or a private real estate company. Municipal and private real estate companies are not performing on totally equal terms in the property market. A municipal company in Sweden has a public service mission. The consequence due to that mission is that they have limited yield potential but on the other hand the right to certain subsidies. They are also limited by the law of public purchasing (in Swedish: Lag om offentlig upphandling) in the investment process.

The trend towards increasingly large farming units raises questions regarding how to better monitor production. Larger units make the impact from possible errors more severe, which increases the pressure on management supervision. To cope with management issues, prevent errors and handle increased demands on traceability and documentation, the Real Time Location Systems (RTLS) concept is making its way into various parts of agriculture. In sectors outside agriculture, RTLS are already being used successfully to track and locate items through nodes at different levels of accuracy, such as room level or the relative or absolute position. Empirical data can be received in real time from the nodes.

Different techniques for precision agriculture have been available during the last decade. Some of them are more widely used than others. The main purpose of this thesis was to investigate the different attitudes to precision agriculture that exists among farmers and advisors in Sweden. Eight advisors and sixteen farmers were asked for their opinion of a number of specific techniques for precision agriculture, such as yield-mapping, precision liming, the Yara Nitrogen Sensor and site-specific fertilization with phosphorous and potassium. They were also asked to describe the way in which the counselling in Swedish agriculture is used and also about it's importance for the adaptation of new techniques. The high costs are mentioned to be one of the most important reasons why precision agriculture hasn't been more widely spread. Several farmers refer to their farms as too small to bear the costs that come with the techniques. The individual interest for technique among the potential users plays an important role.

At the end of 2008, Arla concluded agreements with several supermarkets in southern Sweden. The agreement with the supermarkets excluded Ska?nemejerier from the stores. This meant that Ska?nemejerier lost approximately 7% of sales volume.

Bakgrund Många mammor som fött barn prematurt önskar amning som uppfödning för sitt barn för bröstmjölkens immunologiska faktorer och som en kompensation för att graviditeten avslutats för tidigt. Amningens etablering kan vara komplicerad och kräva tålamod när barnet behöver vård. Beroende på barnets känslighet kan det ta olika lång tid tills barnet kan påbörja amningsträning. En av de viktigaste faktorerna för att amningen ska kunna etableras är att mamman får igång en tillräcklig mjölkproduktion motsvarande den mängd ett fullgånget barn skulle kräva. För att få igång en tillräcklig produktion är det bra att komma igång med urmjölkning så fort som möjligt efter barnets födelse.
