Driva tulpaner i näringslösning eller i jord :

The aim with this thesis is to make a comparison between forcing tulips in a hydroponic system and the forcing off tulips that have been planted in soil. The results are mostly based on interviews with six Dutch and one Swedish tulip forcer and the managing director at the Horticultural Research Centre, Proeftuin Zwaagdijke, in the Netherlands. There are benefits and disadvantages with both methods. Tulip bulbs planted in soil seem to get a brighter colour after forcing, compared with those forced ?in water?.

Optimering av ultraljudssändare- och mottagare avseende räckvidd, strålningsvinkel och energiförbrukning

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

Regional Styrningsproblematik i ett Utvidgat Europa - en komparativ fallstudie av Frankrike och Polen

The aim of this comparative study is to analyse the French and the Polish regional governance in order to see if there are any differences in their regional ruling systems. Further more I will study their different possibilities in taking part in the European Union regional political market. The shape of the regional systems will be explored both organisationally (study of the institutional entities of the regional construction) and functionally (study of the competencies of the regional body etcetera) to focus on its cause on the regional development. My over all focus will be to find out whether regional rule means differently in the countries France and Poland.Several questions are dealt with and the two main ones are as follows; How do the different structures of the form of government in France and Poland influence the governance on the regional level? Do Poland, as a new member state of the European Union, have what it takes to face the challenges of the new membership; or are there a complex of problems arising from the admittance that prevent its regions from fully taking part in the European regional political market?Some of my conclusions are as follows;There are major differences between the two countries when it comes to their regional ruling systems leading to different abilities in taking part in the European regional political market.

Nanostrukturell ytbeläggning på utsatta delar av marina drivlinor

Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

Made in Taiwan: Om identitetskonstruktion i Taiwan

Taiwan's recent democratization seem to have rallied a wider support of the notion of a national identity amongst its citizens which in the year 2000 led to the election of the pro-independence party DPP and President Chen Shui-bian. Meanwhile, China insists on the "one country, two systems" formula, regarding Taiwan as merely a Chinese province, and continues to fight any Taiwanese initiative towards sovereignty. Through a narrative perspective, this essay analyzes the self-conscious national identity-building quest embarked upon by DPP and President Chen Shui-bian. The analysis consists of three parts. Firstly, a text-analysis of President Chen Shui-bian's speeches is conducted to examine in what way he enforces and legitimizes the identity-building-process through narratives.

En pilotstudie av unghästars användning av ligghall i grupphållningssystem

Today, individual indoor stalls and individual outdoor paddocks are the most common way to house horses in Sweden. The way that we manage, house and feed the horses are not optimal for the species natural basic behavioural needs. However, the awareness of this grows in the context of research and the emergence of alternative housing systems. One of the alternatives to the traditional format in individual boxes is called group housing. Group housing systems allow horses to live in herds and they can choose how they want to distribute the hours of the day between movement, resting and foraging. The purpose of this study is to examine how frequently the young horses in a group housing system use the indoor lying area.

En inklusiv etik på goda grunder? -Vår livsstil och djurens liv, en filosofisk och teologisk diskussion

The relationship human has to animals are complex and I discuss this from a theological and philosophical perspective in this essay. I ask on what grounds, with what arguments and how one could live with an inclusive ethic. I discuss the philosopher Peter Singer and the theologian Andrew Linzey to see their agreements and differences. Linzey has a mystic influence built into the theological perspective. Swedish activists and authors Pelle Strindlund and Annika Spalde call their way of life the ?Way of love? and show an animal-inclusive ethic built on a Christian mystic ground..

Anbudskalkyl mer användbar i byggprocessen

This report is written for a consultant networking company with the purpose to review the development ofthe company's remote connections from a user friendly and security perspective.This includes an investigation of the possibilities to consolidate existing authentication methods foraccessing customers. The problem lies in the amount of methods being used. Through case study wefound that smart cards, SMS-service, software and hardware tokens exist.The only method feasible from a security perspective is smart cards. Since the method is not commonlyused by the company's customers a standardization of it would be counterproductive.Also, the purpose of this report is to investigate how the ongoing internal development of the remoteconnection will affect the company's clients. Within this framework we have also verified a designsuggestion.We interpret, after the completion of the case study, that the internal development of the remoteconnection is marginally affected by legal perspectives.

Nationella proven i matematik? en tillgång för läraren? : Hur några lärare använder sig av resultaten på de nationella proven i matematik

The purpose of this qualitative study is to investigate how some teachers make use of the results of the national tests in mathematics to plan their teaching. The questions are how they plan their teaching in mathematics and if they use the results of the national tests to compare with their own teaching.   Five teachers in mathematics has been interviewed. I have used unstructured interviews with open-ended questions, and I have been able to ask follow-up questions based on their answers. The analysis of the survey is made from a systems theory approach.  The result of the survey shows that teachers make use of student performance to look at their own teaching of the current group of students. However, there is not enough time to rehearse and repair the deficiencies discovered in the national tests, which for some is perceived as a stress factor.

Utvärdering av kalkstens egenskaper med laboratorie- och fältmetoder.

A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.
