Reducerad jordbearbetning : en fallstudie
This is a study made because I would like to see how much money can be saved when
reduced soil preparations is used. This is a case study, the farm is located in the north
vest part of Skåne, Sweden.
I have calculated with four different soilpreparation methods.
Alternative 1: Conventional soil preparation, the way the farm is managed today.
Alternative 2: Ploughing on depth of 12 centimeters, with a ridge packer followed with
sowing.
Alternative 3: Eco-tillage
Alternative 4: Direct drilling
The results of my study showes that Alternative 2 is the most profitable. Alternative 4 is
very good if you see to dieselexpenses and hours of work, but the yield is far to low.
If the numbers are further analized, it showes that in spring barley the differense
between Alternative 2 and Alternative 4 is at a minimum. So if there is lack of time for
one reason or another, this might be an alternative in spring barley.
The differense in how the farm is managed today and the most profitable alternative in
the study, Alternative 2 showes that it can be saved up to 60 940 SEK..
Utvärdering av grafisk utvecklingsmiljö för programmering av signalprocessor
This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.
Förekomst och grad av osteokondros i distala radius och ulna hos konventionellt och KRAV-uppfödda slaktsvin :
The occurrence and degree of osteochondrosis was studied in 64 pigs raised in conventional systems (45) or organically according to KRAVs principles (19). In this blind study the growth plates of distal radius and ulna were examined macroscopically and radiologically searching for pathological lesions. One significant difference was shown in this study. Conventionally raised pigs diagnosed with osteochondrosis had more severe lesions in the distal growth plate of radius and ulna than the corresponding group of pigs raised organically. No significant difference was shown between the groups when all pigs were included.

Jämförelseförsök mellan ogräsharvning och radhackning :
The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010.
The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing.
In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment.
The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment.
Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow..
Electrical track system : Utveckling av ett nytt system, innefattande elektrisk golvlist och uttag, som medger flytt av de traditionellt fasta vägguttagen
This degree project concludes the Innovation and Design Engineering programme at Karlstad University. The project was carried out by David Brocker, Erik Hallberg and Andreas Hertzman during the spring of 2006 and corresponded to 15 weeks of work per student. Assigner was Martin Larsson at Arexor and instructor at Karlstad University was Monica Jakobsson.Arexor has a patent to a construction of an electrical skirting board with moveable wall sockets, called Electrical Track System. The lowest parts of the interior walls along the floor are today almost always covered by a conventional skirting board. Arexors patented product replaces that with the possibility to move and increase the number of wall sockets by choice along an electrical skirting board.
Varumärkesbyggande genom marknadskommunikation : En fallstudie av varumärket Hollister
This study aims to describe how a company behind a well-established brand in the fashion industry has strategically chosen to communicate with their target market. Interviews with four individuals in different positions within the company have generated qualitative data, which is presented and analyzed in relation to the theoretical frame of reference in this study. The results show that the company does not use conventional marketing, but relies rather on marketing based word-of-mouth generated by its customer base due to its unique store concepts. Previous research has shown that this type of marketing strategy is effective and beneficial to the brand equity, a conclusion that is demonstrated to also apply to the survey object of this study. Furthermore, it is also shown that this is largely due to the distinct and coordinated image that the company maintains through strict standardization..
Vilken effekt har lärkrutor på ogräsfloran vid ekologisk höstveteodling? :
This study forms part of the R&D project "Improved survival of bird chicks in organic fields" managed by the Rural Economy & Agricultural society in Uppsala. The skylark (Alauda arvensis) is a species that has decreased drastically in Sweden as a consequence of more intensive cropping.
Studies in England have shown that skylark reproduction can be greatly improved within
conventional fields, at a low cost, by establishing patches of bare ground (skylark plots).
Within conventional farming, herbicides can be used in case a weed problem arises due to
implementation of these skylark plots, whereas this is not allowed in organic farming. This study examined the effects of skylark plots on the weed culture in organic autumn-sown (winter) cereals and whether weeds might cause long-term problems to farmers.
The study was conducted in two parts; a field study and a review of the literature regarding the weeds observed. The field study was carried out in 2007 during three weeks in June and three weeks in July, on eleven organic fields with winter cereal in the vicinity of Uppsala.
Interaktion mellan män på Internetforumen Sekreterarakademin & Flashback : där sambandet är köp av sexuella
In this study I will analyze how men who buy sex interact with one another on two different Internet communities: ?Sekreterarakademin? and ?Flashback?. This analysis is carried out in an attempt to challenge the conventional image of the man who pays for sex.The aim is to examine the role of Internet forums for men who buy sexual services related to cross-border, both in terms of standard borders, gender boundaries, boundaries of sexuality and masculinity. I will also attempt to investigate what opportunities that are available to overrun different borders and how these opportunities affect the conditions of the various players. I will evaluate theories such as homosocialtet, hegemonic masculinity and normalization used by KAST (Köpare Av Sexuella Tjänster, the Swedish public support for clients of sexual services) and which are partially consolidated in studies published by KAST concerning issues related to internet based prostitution..
Mikroskopering av opaka faser - en studie från Skyttgruvan, Falun.
In nature there are about 4,500 minerals identified. These can roughly be divided into two groups, opaque phases and non-opaque phases, with the exception that some opaque phases also may act as a non-opaque phase in different circumstances. The division is made on the basis of the optical properties. Opaque phases are nontransparent, which means that a different type of microscope must be used. A conventional microscope uses transmitted light while the microscope for opaque phases or the ore microscope uses reflected light.
Investering i spannmålstorkning och lagring på gårdsnivå : en jämförelse av ett silotorksystem med omrörare och en konventionell anläggning
The current situation for Swedish grain farmers facing a situation with decreasing profitability makes it necessary for the farmers to find ways of increasing the margins in their grain growing. Decreasing profitabilities along with Lantmännens closing of grain elevators contribute to the necessity for farmers to invest in grain storing and drying at the farm. By investing in capacity for drying and storage of grain on the farm it is possible to recieve a higher price on the grain sold due to the possibility to sell when the price is higher compared to the harvesting season.
An investment in grain drying and storage with a relatively low investment cost that recently has appeared on the Swedish market is the grain stir drying system. This study contains a comparison of an investment in a grain stir drying system where the grain is dried and stored in the same silo and a conventional drying and storage system.
Vidriga vuxna och förslagna barn : en studie av det karnevaliska och groteska i Roald Dahls författarskap
The main aim of this study is to analyse the grotesque characterization of adults in four novels by Roald Dahl, from Michail Bachtin?s definition of the carnival-grotesque in Rabelais and his world. From this view I have examined how the conflict between children and adults is described in these books, and to what extent the grotesque motifs have a function in this conflict.For this purpose I have applied theories of the literature-grotesque by Michail Bachtin, and of the meaning and function and ? in this context ? the necessity of fright and horror in children?s fiction, in particular by Bruno Bettelheim and J.A. Appleyard.
Anaerob psykrofil behandling av hushållsavloppsvatten i UASB : Utvärdering av kapaciteten hos en två-stegs UASB-reaktor för behandling av hushållsavloppsvatten
Hammarby Sjöstad is a new district in southern Stockholm. A main objective with the Sjöstad project was to halve the environmental impact compared to other construction work. The environmental goals involve a halved water consumption rate, a local treatment of storm water and trials aiming to extract nutrients from the waste water. Sjöstadsverket is an experimental treatment plant used for testing new treatment processes for domestic waste water from Hammarby Sjöstad. The results are to be compared with the conventional process used at Henrikdals treatment plant today.
Resebloggens relevans - innehållet som fångar läsaren
This study investigated whether in-situ audiometry, delivered via hearing aids, is a better option as a basis forprescribing hearing aid amplification, compared to conventional audiometry. By examining the real ear insertgain (REIG) in 29 ears (18 subjects), that had been fitted with a hearing aid programmed using both conventionalaudiometry and in-situ audiometry, the study looked at whether in-situ audiometry based prescription is closer tothe NAL NL1's fitting target than audiogram based prescription. The hearing aid Siemens Pure 7mi with speakerunit M was used on all participants. The results showed how in-situ audiometry based gain at certain frequenciesis more consistent with the target curve, especially at 1000, 1500, 2000 and 4000 Hz. It was not establishedwhether the findings of the study were statistically significant.
Tankar om plöjningsfri odling :
The margin in crop production is more and more less and it forces the producer to check
out how to reduce the cost of establishment of new crop. One way to reduce the cost in
establishment is to begin with plough less farming. It saves money and time compares to
conventional soil preparation with plough and harrow.
Not all soil types are god for plough less farming and should be continued with
ploughing (mainly light soil), but other soil types working very well with plough free
farming.
If you want to success with plough less farming you have to think in new lanes. One of
the things you have to think about is to not grow too much cereal after cereal. Low
stubble is important when you harvest the crop and also to spread and chop the straw
well.
I have in this work interviewed some farmers and farm advisers in Östergötland to see
which thoughts they have about plough less farming.
Ungdomars synsätt på politik : - former, innehåll & uttryck
Abstract Youths and adolescents have for a long period of time, and at a high degree, beenabsent from the party political stage. The causes for this have been discussed inthis essay through a quantitative survey made in an upper secondary school class,consisting of some 19 subjects in the municipality of Kalmar. Tied together withrelevant literature and discourse on the subject, the essay has dealt with thepossible societal-, system- and individual barriers for political interest andinvolvement. Central questions for this essay has been for instance; age, gender,social background, geographical domicile, as well as the decline of ideology, theforms of current party politics, political interest, political engagement and soforth. The concluding remarks contain not only a mix of these barriers existing,not exclusively, for young and adolescents but different ground for them as well.On the one hand, there exist barriers which exclude youth from the conventionalpolitical life, but on the other, the more individualised youth of today, prefer to agreater extent not to participate under the conventional circumstances that partypolitics has to offer.
