This bachelor thesis is intended to gather the knowledge and experimental data on the winter wheat crop production relevant for Swedish conditions, with focus on sowing time, row spacing and seed rate. This essay is a literature study with a minor component based on interviews with farmers producing winter wheat. The work is divided into a background part where basic knowledge of winter wheat physiology, development and environment interactions are described and one part where results of field trials studies are presented. Optimal date of sowing winter wheat depends on annual weather variations. Because it is difficult to forecast the weather the choice of sowing date should be based on weather statistics, production experience and previous results depending on sowing date.

Stump harvest could be found in the late 1970?s and the early 1980?s. And now when the prices on energy are high it has become an interesting topic again. This work has been conducted within Holmen Skog?s stump harvest testing in Norrköping.

The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background knowledge.The tenant-owner?s association Duvan at Petterslundsgatan in Uppsala installed year 1999-2000 a geothermal heating system. The purpose of this installation was that they hoped it would lead to a smaller usage of district heating which would lead to a reduction of the heating expenses for their buildings. The geothermal heating system consists of 19 energy wells and 4 geothermal heat pumps, and it is one of the first systems of that size in the region of Uppsala.

Energy is an essential part of the society and for a sustainable future we need to use the energy resources in a sustainable way. The forest is Sweden?s most important resource for renewable energy and a higher production combined with shorter rotation periods (time from planting to clear cutting) can increase the access to energy. The tree genus poplar (Populus spp.) is interesting as energy resource as it has both high production and short rotation period. But browsing ungulates are a major threat to the establishment of poplar plants and therefore the poplar plantations need to be fenced in today. To use fences is expensive and time consuming; this makes it interesting to find more cost-effective solutions where there is no need to fence. The aim with this study was to look at the ungulates? occupation rate and browsing pressure in poplar plantations without fence.

Glycogen is the storage form of glucose and is used by the skeletal musculature as energy both for intense and endurance events. The glycogen content in the horse?s middle gluteal muscle is more than 600 mmol/kg dry weight, and almost 400 mmol/kg dry weight in the human?s Vastus lateralis. In some special occasions, for example in competitions with several moments on following days, there is a need of a fast muscle glycogen resynthesis. The feed intake is of importance for the velocity of the resynthesis.

The purpose of this study is to establish how a few youngsters have experienced their time in contact families and which, if any, significance their respective ?contact families? has for them today. The study aims to determine the life situation in the youth?s families at the time support through ?contact families? was initiated and the youths? own view of the reasons for this support. We also want to shed light on the meaning that the contact families had on the youth; considering both positive as well as negative meaning.

Syftet med undersökningen är att diskutera synen på läraryrkets status, genom att ta reda på vilka faktorer som kan påverka ett yrkes status. För att kunna analysera den empiri som samlades in kommer Gunnel Colnerud och Kjell Granströms teorier om ett professionellt yrke att diskuteras. Ulfsdotter Erikssons avhandlig om bland annat yrkesstatus och Gerhard Arfwedsons teorier om lärarlöner och kvinnodominans inom läraryrket kommer också att behandlas. Andy Hargreaves teorier används för att diskutera de statusskillnader som redan i skolan präglar eleverna och de fungerar även som ett komplement till Arfwedsons teorier. Undersökningen genomfördes med hjälp av en kvantitativ metod, i form av enkäter.

Bakgrund: Inspirationen till denna studie uppkom av fo?rfattarnas intresse kring identiteter och deras intresse fo?r skapelseprocessen kring deras egna identiteter. Fra?gan som uppkom i samband med starten fo?r studien var vilka vi sja?lva har utvecklas till som blivande civilekonomer och vilka faktorer som hade pa?verkat oss.Syfte: Studiens syfte var att underso?ka skapelse- och fo?ra?ndringsprocessen av en civilekonoms professionsidentitet under studietiden.Metod: Studien a?r genomfo?rd pa? ett kvalitativt tillva?gaga?ngssa?tt. Studien har utfo?rts med en autoetnografisk teknik fo?r att presentera studiens empiri da?r a?ven fo?rfattarnas reflektioner presenteras som en empirika?lla.

The purpose of our essay is to investigate the role of the practice period under supervision from a skilled practioner as a part of the student?s development of knowledge. This essay?s main participants are students who are studying their sixth semester during the spring 2009 at the bachelor program of social work at the University of Gothenburg and active skilled practioners during the autumn of 2008 and spring 2009. The essay has primarily a qualitative approach.

This paper describes Tempus Custode, a smartphone application with which the user may register working hours and travel time during the work day. The application communicates with a database via a server. The data stored in the database may be manipulated using an administrator tool, mainly for the composition of time reports. In this way, the user?s task of time reporting his day is greatly simplified.The application is able to automatically discriminate between work time and travel time, as it continuously fetches positioning data from the smartphone GPS receiver.

The aim of this essay is to find some of the main developing tendencies in the advertisement genre during the period of 1930-2000. The analysis is based on three examples of Gevalia cinema and TV-advertisement. Research findings are the result of using theories from different but relevant sciences, which are media, linguistics and rhetoric. Media studies help to explain the influence of the society and technology development on the advertising business. Linguistics and rhetoric give the main methods and terminology for the basic as well as comparing analyses of the three advertisements in question.

Every municipality in Sweden is responsible for offering its citizens adequate childcare. Parents hand in a preliminary schedule to the preschool for when their child needs to be in childcare, and based on this the preschool staff is scheduled. Some municipalities measure the actual time a child is in childcare. The essay idea comes from when I heard that one municipality was thinking of register the children's actual time in preschools. I started thinking on how to solve such a task.

At present, the Swedish pig industry is in transition. Prices have been low, but feed prices have increased. Therefore, many pig producers have stopped their production. Producers that lack an integrated production may contract piglet?s producers, or may use the mediation services that slaughterhouses provide.

This work focuses on the relation between human and animals and especially on the relation between horses and human. I have brought up the human och horse relationsship, today, and in history and wrote about the behaviour of the horse. Some older studies with human and animal interaction, including animals like dog and cattle are discussed. I have also discussed physiological parameters that might influence the bond and the interaction between human and horse and some critical aspects concerning the methodology when studying this kind of physiology. The purpose of the experimental study was to analyze if common management routines and grooming of horses increases horses interest in making contact with humans. Many horse owners feel that they have a good connection with their horse and factors that can influence the relationsship could be physical contact, feeding or some challange that make the horse trust the human.

The main focus of this study are the textile prints created by Astrid Sampe (1909-2002). Her fabrics can tell us more about her than a biography ever could. They can reveal how we experience patterns, why we are attracted to them and how our preferences can evolve over time. This study examines four different patterns, and the thesis aims to define Sampe and her textile prints using three different theories and a formal aesthetic analysis. Modernistic and postmodernism theories are relevant when explaining the period where the fabrics were created and how Sampe's ideas were conceived during her lifetime.
