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.
Change Lab : Att arbeta med lärande förändring
In order to be able to change, to maintain competitiveness as a company in a world where rapid changes is part of the daily life, it is crucial to have knowledge and methods in how to change. One method, originally developed in Finland, is the Change Laboratory. This method is said to be efficient, not only concerning change aspects but also learning, since change and learning in this method is intertwined. This Master Thesis (20p.) tells about the process of conducting a Change Laboratory with a Swedish high-tech company and analyses factors in the process that makes change possible..
Strategi, Läge & Varumärke
Goal: To describe which evaluation method is used by Swedish retailers to assess a potential retail location and to describe to what extent the retail brand effects this strategic decision. Design: Analysis of ten interviews with companies within five retail sectors in Sweden. Main study: Indication of what methods are used to evaluate a location and how a company's retail brand affects the decision. Results: Retailers use a mix of theoretical methods to evaluate the location attributes and possible profit. Most common among mixtures was an application of the analog method, residual method or the checklist method in combination with a financial assessment.
Utvärdering av Transportstyrelsens flygtrafiksmodeller
The Swedish Transport Agency has for a long time collected data on a monthly basis for different variables that are used to make predictions, short projections as well as longer projections. They have used SAS for producing statistical models in air transport. The model with the largest value of coefficient of determination is the method that has been used for a long time. The Swedish Transport Agency felt it was time for an evaluation of their models and methods of how projections is estimated, they would also explore the possibilities to use different, completely new models for forecasting air travel. This Bachelor thesis examines how the Holt-Winters method does compare with SARIMA, error terms such as RMSE, MAPE, R2, AIC and BIC will be compared between the methods. The results which have been produced showing that there may be a risk that the Holt-Winters models adepts a bit too well in a few variables in which Holt-Winters method has been adapted.

Att rekonstruera förhistoriska odlingsförutsättningar : första steget i en metodutveckling.
The aim of this work is to take the first step into a development process, with the intention to find a way of making prehistoric soil fertility a variable in archaeological landscape analysis. A pilot study is performed on the Mälar basin area, where four topographical and geological factors are reclassified and then combined, resulting in a map which expresses a relative indication of agriculture potential. The map is then compared to the distribution of Migration Period graves and gold finds. This, however, does not mean that the technique is tied to a certain prehistoric period. Because the work is intrinsically experimental, the technique as a whole is finally discussed and evaluated, and suggestions of improvements and further studies are made..
Jämförelsestudie för tre olika metoder att beräkna genomstansning i betong : Skillnader i genomstansningskapacitet för metoderna i BBK04, EK2 och BHB
Before the European construction standards were introduced in January 2011, it was mainly themethod in BBK04 that was used for calculating punching capacity in concrete structures, and in lesscommon cases the method in BHB. The method of BBK04 is easy to use and have had the samestructure since the first was published in 1979. The Concrete handbook method (BHB) where usuallyonly used when a higher punching capacity was needed and the cross-sectional height where fixed,calculations using this method entails more work, but will in return usually give a higher capacity. Italso allows the use of shear reinforcement to increase the cross-section capacity. The method ofcalculating punching shear in EC2 differs largely from the methods of BBK04 and BHB.
DISA-metoden : En undersökning om gruppledarnas bedömningar av genomförandet och av metodens framtidsutsikter
Twice as many women as men suffer from mental ill-health. The negative trend of mental problems among teenagers continues. In certain places in Sweden, 40 per cent of the teenage girls have outspoken symptoms of depression. This is why it is important to observe mental ill-health in a public health perspective. One effect evaluation of the DISA method (Depression In Swedish Adolescents) drew the conclusion that this universal depression preventive method is well working. The DISA method includes cognitive behavioural techniques that change negative pattern of thinking, give practice of communication, strategies of problem solution plus exercises to strengthen the social network.
Skola och kompetensutveckling, viktiga faktorer för socialisationsprocessen : En studie om ensamkommande barns socialisation i deras nya samhälle
The study discloses unaccompanied children´s socialization in their new society. The purpose of the study is to investigate how unaccompanied children's schooling is an important factor in their socialization and skills development in their new society. For example, we have chosen to illustrate how their school works and if and whether the teachers receive the support they need in order to help children develop their skills so they can find their way in society. The research is based on three different methods. The first method is based on literature research.
Effekten av individanpassade sulor hos personer med arbetsrelaterade besvär i ländrygg och nedre extremitet: En Single Subject Experimental Design (SSED)
Introduktion/bakgrund: På ett företag där det förekommer truckar skall personalen enligt lag använda truckskor som skyddsutrustning. I nuläget använder personalen inte sina truckskor på arbetstid eftersom de anses vara obekväma och öka deras besvär från kroppen. Det har visat sig i en rad olika studier att användandet av sulor i skorna kan reducera besvär ländrygg och nedre extremitet. Syfte: Syftet var att studera vilka effekter en individanpassad sula kan ge på arbetsrelaterade besvär i ländrygg, höft, knä eller fot, hos personal med stående arbete. Metod: Studien genomfördes som en Single-System Experimental Design (SSED) med ABA-design.
Det praktiska intellektet: timmerlagning med mallbr?da som exempel
This thesis presents a method of making repairs in log houses. The purpose of the thesis is to use this
method to exemplify crafters practical intellect. The method is based on the use of a template board to
transfer the measurements onto the new log. There is a dearth of literature dealing with timber repairs,
and the literature regarding using a template board for this is non-existent. The description of this
method has therefore been compiled from interviews with active timber crafters.
Ett undervisningsförsök att skapa meningsfullt lärande i frisörens grundläggande tekniker
This Independent work is about testing a method to create meaningful learning and a deeper comprehension in matter of basic hairdressing techniques. I got the idea for this method by reading literature related to my education to become a teacher for hairdressers, the new schoolreform and from my own experience of a teaching method that I saw an opportunity to develope. My teaching method was based on first teaching the pupils the basic techniques, and then give them an assignment were they were to find out their own final result by using a picture for inspiration. They were given an assignment description with certain frames but with freedom of choice how to get to their own final result. By making a job description and a headdrawing to show how the work should be done, and during the process try different ways to achieve the best result, my idea was that a deeper understanding and a feeling of meaningfulness would appear.The result shows that the pupils by freedom within frames experienced meaningful learning and thereby deeper understanding when it comes to basic hairdressing techniques.
Effekter av högt kaliumintag på magnesiumbalansen hos mjölkkor :
Magnesium is one of the most important minerals in the body and it participates in many essential processes, such as energy metabolism and protein synthezis. Magnesium deficiency in cattle may occur when they are let out for pasture in the spring, and is associated with tetany, known as grass staggers. A high yielding dairy cow often loses more magnesium daily in the milk than she has available in the body, and magnesium thereby needs to be provided in the feed to prevent the cow from being affected by deficiency symptoms.
The uptake of magnesium is mainly located to the rumen and is not regulated by hormones. The surplus is excreted in the urine by the kidneys.
Återvinning av näringsämnen från hushållsspillvatten med omvänd osmos
Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.
