The Swedish consumption of lamb a increasing, and today we yearly eat a kilo of lamb per person each year. As a consequence the Swedish degree of self production according to lamb is steadily decreasing, and is today about 39 %.Today Swedish Meats is now cooperating with the Swedish lamb breeders organisation to raise that percentage. At the same time the European Union presents a new agricultural reform, the MTR (Mid Term Review). The shape of this new reform is not yet fully known, but the general policy has been more or less outlined. The new reform is split into three propositions: the farm model, the regional model and the mixed model.

Syftet med vår uppsats var att med hjälp av Model Confidence Set (MCS) finna de bättre presterande modellerna bland de mest ?kända? och undervisade volatilitetsmodellerna. Vidare har vi även rankat dessa modeller inbördes. Eftersom prognoser om volatiliteten är mycket viktigt vid prissättningen på derivat, i detta fall ett räntederivat, är ämnet ständigt intressant. Med Model Confidence Set fann vi ett set av bättre presterande modeller utifrån vårt urval av ursprungliga modeller.

There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

ABSTRACT Infertility is a medical condition that affects approximately 16 % of Swedish couples in childbearing age and is a condition found in both men and women. When a couple has been trying to conceive for more than 12 months without success they need to see a health care provider. Infertility can be treated with medicine, insemination or assisted reproductive technology such as in-vitro fertilization (IVF) and intra-cytoplasmic sperm injection (ICSI). The aim of this study was to validate a morphokinetic selection model, KIDScore? D3 Basic, against morphological selection model that is currently in use at the Fertility unit at University hospital in Orebro.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

The transition from having been under another country?s control to becoming a democratic country can, many times, pose difficulties, which has proven itself to be quite common. Estonia and Moldova?s processes towards a democratic regime are two examples of countries with varied success in the final transition phase.When the USSR (Soviet union) fell and collapsed in 1991 Estonia was well on their way from having a communistic ruling to a democratic one due to the fact that their democratic work had already begun a few years prior to 1991. After the collapse Estonia continued with their democratic work and in 2004 the country became a EU member state.

24 years have passed since the Chernobyl accident when radionuclides were spread over largeareas of Europe, including the Scandinavian countries. Today, measurable activities of 137Csare still observed in many Swedish ecosystems.Ants (belonging to the order Hymenoptera) are social insects which collect organic materialfrom a large area around their nests. This study focuses on the 137Cs activity in ant nests andthe cesium accumulation in these nests. The aims were (1) to estimate the 137Cs fall-out in1986, (2) estimate the radiation exposure of ants and (3) find how 137Cs is distributed in an anthill. Seven ant hills (occupied by the species Formica polyctena) were studied near the villageof Hille, situated north of the city of Gävle in central Sweden.

In a comparing survey this thesis investigatesclassification systems for dams in Sweden, Norway,Finland, Switzerland, Canada and USA. Theinvestigation is aiming at an understanding of howpotential consequences of a dam failure are takeninto account when classifying dams. Furthermore,the significance of the classification, regarding therequirements on the dam owner and surveillanceauthorities concerning dam safety is considered andreviewed. The thesis is pointing out similarities anddifferences in the line of dam safety.The survey of dam safety is firstly based upon legalrequirements in the different countries andsecondly on guidelines regarding dam safety. Damowners generally are ultimately responsible for thesafety of their dam, and often have their ownroutines regarding how this safety is to be achieved.In this thesis, however, the legal requirements aremainly focused upon.The investigation has resulted in an outlining ofeight areas, where the classification systems in thevarious countries have been compared.

We have been looking at three different types of agriculture in Södermanland, in the middle east of Sweden. We call the different types for Intensive, Extensive and Mix. The purpose is to get an economic defensible plan for how to run different farm sizes. We also have been looking at the working hours and how many hours the different types will give. We have a farm called Taxinge Gods as our pilot farm. Taxinge Gods grow 407 ha land and is located 60 km southwest from Stockholm.

I denna studie har vi haft som avsikt att jämföra två modeller som förklarar avkastningen på aktiemarknaden. Modellerna är Capital Asset Pricing Model (CAPM) och Fama-French trefaktormodell(FF3). Undersökningen har gjorts på Nasdaq OMX Nordic Stockholm över perioden 2002 till 2012. Vi har valt att göra denna undersökning för att se huruvida FF3 med två extra faktorer kan förklara avkastningen på aktiemarknaden bättre än CAPM. Sex portföljer konstruerades och vi har visat att FF3 statistiskt signifikant förklarar mer än CAPM för fem av sex portföljer.

Accounting for financial instruments can either be based on a transactions approach or an eco-nomic approach. Under a transactions approach instruments are reported at cost whereas under an economic approach instruments are reported at fair value. Hence, under a transactions approach realization becomes a criterion for recognizing fair value fluctuations as revenue whereas under an economic approach it does not. A mixed model is defined as a combination of the transactions approach and the economic approach insofar it records some accounting items at cost and other items at fair value. The mixed model gives rise to an issue commonly referred to as an accounting mismatch.

 In the global society of today it takes more and more to become a successful purchaser. One part of this is to understand distinctions between different countries. The first and the biggest thing that you think about are the languages. Of course this is a big obstacle but there are also big cultural differences to be considered. According to Van Weele (2002) this is something that not, until these days, have been prioritized but today it is becoming more common in the industries.The biggest question we asked ourselves before the work started was how cultural and verbal differences affected the global procurement on Husqvarna.

The purpose of this study has been to examine what it is in the situation that affects which leadership that is applied on the members of the organization. Our questions that we have explored were; What is it in the situation that influences the leadership applied on an individual or staff group? What similarities and differences have emerged by Hersey and Blanchards situational leadership model?Further, we used qualitative semi-structured interviews at the interview procedures with three managers and three employees. Hersey and Blanchards situational leadership model and Goffmans theory in the book "The presentation of self in everyday life" have been used as a foundation and inspiration in this study.We have found that circumstances like the size of the staff group along with the organizations financials and the resources affect the leadership behavior and how well it is matched with the employees. The function of the leaders position in the context, and the purpose of the situation influences how the leadership is formed.

Fuktskador på uteluftsventilerade vindar är ett ökat problem, i det mer miljömedvetna Sverige. Genom tjockare vindsbjälklagsisolering minskar både energiförlusten genom bjälklaget och uppvärmningsbehovet i huset, men hur många funderar på vad som händer med det förändrade klimatet på vinden och hur det kan påverka fuktförhållandena i utsatta delar av konstruktionen.Studier från Chalmers Tekniska Högskola har framställt ett fuktberäkningsprogram för uteluftsventilerade vindar vid namn Simple Cold Attic Model. Programmets funktion och potential har prövats i denna rapport genom en beräkningsanalys av en uteluftsventilerad vindskonstruktion. Försök till att förbättra fuktsäkerheten i konstruktionen har utförts och redovisas i rapporten. Studien har påvisat att den studerade konstruktionen inte är fuktsäker om den uppförs i Stockholmsområdet. Det visades även att aktiva val i konstruktionen kan förebygga fuktskador. Studien har påvisat vikten av inte beräkna med medelår för klimat och hur det påverkar beräkningsresultatet av mögeltillväxt.
