Integrerat växtskydd i svensk jordgubbsodling : attityder bland odlarna till genomförande av det nya direktivet

This study was conducted at VikingGenetics' bull breeding station in Falkenberg, Sweden. The bulls waiting for the results of their progeny testing at this station are either kept in group housing or individual housing. Since both of these housing systems have advantages and disadvantages, it was in the interest of VikingGenetics to know which of these housing systems is the best. The aim of this study was to investigate the welfare of the bulls in these two housing systems through behavioural observations and the use of activity monitors. In the preparations for the study 16 bulls, 8 in each housing system, were chosen.

Systemförvaltningsmodeller ? verklighetsbeskrivning eller idealiserad bild?

This study will shed light on the subject of system management and system management models. It is important that everyone within an administrative organization understand business objectives and needs of the users who work with the systems. It is vital for the activity to form a structured approach for its management, which includes a system management model. Every company has its individual system management model that is tailored to support their management of a business IT systems. According to Brandt (2000), a system management system model is defined as "an idealized image of how you want the system management work is conducted".

?Har man en chans att påverka ska man göra det?

Folk blir mer och mer medvetna om den påverkan som bekämpningsmedel har både på människan och på miljön och väljer därför ekologiska alternativ i större utsträckning. Detta leder till att efterfrågan på ekologiska produkter stiger och antalet restauranger som väljer att erbjuda ekologiska produkter som vin ökar. Det innebär också att serveringspersonalens kunskapsnivåer om ekologiska viner och dess olika märkningar måste öka för att man skall kunna svara på gästers frågor.Syftet med studien är att jämföra två restaurangchefers inställning till ekologiska viner och vilka faktorer som påverkar restaurangernas val av vin, samt vilka faktorer restaurangcheferna tror påverkar gästens vinval. Genom en kvalitativ studie av semistrukturerade intervjuer med två restaurangchefer blev resultatet att ekologiska viner och konventionella viner i samma prisklass anses vara likvärdiga i smak och kvalité. De faktorer som påverkar restaurangens val av vin är personalens personliga inställning, gästens val samt det övergripande miljötänket restaurangerna har..

The allotment plot : osäkrande som designstrategi

During the spring semester of 2009 I have participated in what was to become the project The Allotment Plot; a collaboration between the Swedish University of Agriculture and the Wanås Foundation. As one of six students in landscape architecture I have experienced a group based learning process with the point of departure in the designing of an organic and experimental kitchen garden at Wanås, a sculpture park for contemporary art. The project came out as neither us nor any other of the people engaged could have guessed. What was meant to be a garden turned out to become an entire cultivation movement. As students, we have gained a lot of experience through praxis; experience that will be valuable for our future profession. The project has also opened up the possibility to question and reflect upon what our profession and education could or should be about. This thesis focuses on the role of communication and the production of communicative tools in design processes and landscape architectural practice. It discusses how communication may be used in an exploratory and ?un-securing? way, and how this may dislocate the professional role, especially in situations where the design action, as in the case of this study, demands a high degree of transdisciplinarity and collaboration. .

Val av teknik för hastighetsmätning i kallvalsverk

An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.

Studier av mjölkbarhet automatiskt mätt i mjölkningsanläggningar :

Milkability or ease of milking, has higher importance today for Swedish dairy cattle producers after the introduction of milking parlours and automatic milking systems. Milkability is the cow?s ability to quickly milk out and be completely milked. There are several measures of milkability available. Today the farmer measures the traits subjectively in relation to the conformation scoring of the cow 30-270 days after her first calving.

Energy from municipal solid waste in Chennai, India : a feasibility study

Solid waste management is one of the most essential functions in a country to achieve asustainable development. In India, it has been one of the least prioritized functions during thelast decades. The most common ways to treat waste in India today are open dumping anduncontrolled burning. These methods are causing severe environmental pollution and healthproblems. India is one of the world?s largest emitter of methane gas from waste disposal.Since methane is a strong greenhouse gas, even small emissions have large impact on theclimate.

Miljöpåverkan av äggproduktion : En jämförelse mellan Lilluns ägg och andra svenska äggproducenter

The purpose of this report was to compare Lilluns egg production with other Swedish egg producers based on the flow of nutrients (nitrogen, phosphorus and potassium) in the egg production systems. The main focus in the report was the utilization rate of the forage and the excess of nutrients per kg egg. Additionally, the purpose was to identify the environmental impact from Lilluns egg production and compare the results with other egg producers. The inflow of nutrients associated with forage and poultry was compared with the nutrients that were exported from the production. All of the egg producers in this study had an excess of nutrients.

Lönsam mjölkproduktion : en fallstudie

Ravelsmarks gård have now reached the stage when there are few options for the future. The options are either a construction of completely new farm buildings or a winding up of the milk production. Present on the farm today there is 65 dairy cows plus recruitment. 44 cows stand in long-stalls and 20 cows stand in short-stalls. The objective of this study was to examine the profitability of a completely new cowshed. In order to get costs for investments different milking systems and equipment for feedstuff have been compared. The systems in the investment budget have been chosen on recommendations from advisers, salesmen and on the basis on what is suitable for the farm. One system where a so-called mix feeder wagon is used for the roughage seemed to be best suited for Ravelsmark. The different prices obtained for the manure well show that there are possibilities to decrease the investment costs.

Studie av värmeflöden i befintligt bostadsbestånd : Utvärdering av energieffektiva besparingsåtgärder

The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.

Microstrip Solutions for Innovative Microwave Feed Systems

This report is introduced with a presentation of fundamental electromagnetic theories, which have helped a lot in the achievement of methods for calculation and design of microstrip transmission lines and circulators. The used software for the work is also based on these theories. General considerations when designing microstrip solutions, such as different types of transmission lines and circulators, are then presented. Especially the design steps for microstrip lines, which have been used in this project, are described. Discontinuities, like bends of microstrip lines, are treated and simulated.

Motivation in Knowledge Intensive Firms - More art than science

Workers are more demanding than ever and stay a shorter amount of time within the same organization. For this reason we wanted to look further into how organizations work with motivation in order to create success in Knowledge Intensive Firms. The complexity of knowledge workers formed the base for our interest within the subject. The purpose of our thesis is to reflect upon what is written about the motivational effects of recruitment and reward strategies in Knowledge Intensive Firms. Further our essay is based on an abductive advocacy.
