Processutveckling av borstgradning
During the milling of Sandvik Coromant?s world leading Drill with replaceable inserts,the CoroDrill880©, burrs appear around the milled surfaces. The burrs are removedusing different methods, one of which is deburring with special brushing machines thatare integrated into milling cells. The machines of the type Sinjet, use a Siemensguidance system. The deburring results are not satisfying and manual deburring isrequired afterwards.
Torkning av vallfrö :
In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the
fields, this is primarily used as feed for livestock. To get a good seed, you need to
handle the crop carefully from planting to delivery. The part that I have been
interested in, is how to dry the harvested seed with out destroying the growth in the
small seed. This is very easily done if you aren?t careful during the drying period.
Traditional milk production in cattle in a semi-arid area in Kenya
Livestock of pastoralists provide meat, milk, blood, dung and are useful for transportation purposes. In semi-arid and arid areas with very low precipitation the herder must often walk far distances to feed the livestock. This affects the animals? production, especially of milk. Previous studies have investigated how to improve milk production in terms of milking strategies in cattle.
Mjölkproduktion : planering för om-, till- och nybyggnad
The objective of this thesis was to get more knowledge about how to design a dairy
farm reducing the working hours and the work tasks whit high work load. I will try to
reduce the working hours and the tasks whit high work load on my own farm witch I
am about inherit. Today, the old stanchion barn has room for about 60 cows and 74
young cattle and need two men to run it every day. The total acre is 188 hectare, 100
hectare forest, 65 hectare farmlands and 23 hectare natural pasture.
I have studied two solutions. In the first solution, I will use my old barn for young
cattle and build a new barn for the cows.
Variation in piglet mortality between and within satellites in a sow pool
The piglet mortality rates have become a major issue in today?s pig production. While other production traits such as number of born piglets or produced piglets per sow have been improved, the mortality rate has escalated. High mortality rates before weaning does not only affect the economy but must also be looked at as both an animal welfare problem and an ethical issue. The background to this problem has been addressed many times, and its salvation has also been addressed by breeding.
Norrländsk träpellets i Europa?: bioenergi i Luleå AB?s marknad i ett europeiskt perspektiv
Bioenergi i Luleå AB är idag en av Sveriges större tillverkare av träpellets och den svenska marknadens efterfråga är god och väntas öka de kommande åren. På senare år har även den europeiska marknaden börjat röra på sig och det finns ett visst intresse att utöka exporten till dessa marknader. Denna uppsats syfte är att estimera efterfrågan på träpellets i Europa och analysera hur en export för Bioenergi i Luleå AB är möjligt. För att uppfylla syftet har en efterfrågemodell använts och estimerats utifrån ett paneldataset. Med hjälp av prisuppgifter på träpellets och alternativa energikällor för 2002-2005 skattas efterfrågan för träpellets för 19 europeiska länder.
Automatic Trimmerhead
Automatic trimmerhead is an examination project for making an automatic trimmerhead for grass trimmers with the user and functionality in focus. Our perception is that a happy user is a user who can pick up his or her trimmer, use it and put it back to its place when the job is done. It should not be necessary to interrupt work and perform maintenance on the machine just to make it work as promised.The project has been made in collaboration with the company Husqvarna, which is one of the biggest actors dealing with garden machinery on the market. Together we determined the project goal, ?To invent, construct and test a brand new concept for how an automatic trimmerhead can look and function?.At this day there are several different automatic trimmerheads on the market, both semi and fully automatic.
Uppbyggnaden av ett foderstatsprogram för dikor :
The object with this work was to create a simple feeding program for beef cows. Another object was that I could learn more about the properties and functions of Excel and Visual Basic.
I used parts of a program I designed a few years ago. This old program was neither user friendly nor had it an appealing layout.
Initially I decided how I wanted the new program to appear and on which foundation it should be built. I designed various forms into a spread sheet, such as lists and multiple choice buttons. Using VBA (Visual Basic for Application) I could create macros, which used the information chosen in the lists and with the multiple choices to calculate the feeding requirement or the feeding plan.
Hur hållbar är serogrisproduktion? :
Raising pigs in absence of a number of certain diseases is called Seroproduction in Sweden. Internationally it?s called SPF (Specific Pathogen Free) ? Production. It results in higher growth, lower feed consumption, and lower medicine consumption. The pigs are produced under the same concept, but the rules vary a bit between countries.
Transition from nomadic pastoralism to livestock based agro-pastoralism : the case of animal husbandry in West Pokot, Kenya
West Pokot County is located in North Western part of Kenya where the previous lifestyle was nomadic pastoralism. However, in recent years the semi-arid county has been under
dramatic developments and a sedentary agro-pastoral lifestyle is now growing. This is a major change in production systems and there is a big knowledge gap especially for the livestock based agro-pastoral systems. The main objective of this study was to investigate
the current situation of animal husbandry in West Pokot. Twenty farmers were interviewed in Chepareria Division, using semi-structured interviews to investigate if the use of enclosures have had any effect on animal husbandry in West Pokot and if so, how have this method affected the animal husbandry? The results of the study indicated that there is a difference in animal husbandry between farms using enclosures and farms not using enclosures.
Fysiska strukturer i Umeälvens gamla älvfåra och dess inverkan på laxsmoltens utvandringsframgång
The survival of hatchery reared smolts is generally low after release. To get a better understanding of what variables affecting migration success, Atlantic salmon smolts were studied during their out-migration in the old river channel in the lower part of river Umeälven. The area consists of shifting habitat and complex structures which causes difficulties for smolt on their migration out to sea. The aim of this study was to try to determine the effects of feed restriction, fin conditions and different physical barriers in the river, on the migratory behavior of Atlantic salmon smolts in the river Umeälven.
The river was divided into six different sections using acoustic receivers strategically deployed along the river. Two-year old hatchery-reared smolts (n=150), in three different weight classes, were tagged with acoustic transmitters.
Glycerol till mjölkkor : effekter på våmmetabolismen
Glycerol is essential for the lipid metabolism of both plants and animals. Glycerol is formed in the rumen by hydrolysis of lipids from the feed. Glycerol is also a by-product from the production of biodiesel from rapeseed oil and other fat sources. Glycerol might be used as a dietary glucose precursor for dairy cows in similar ways as propylene glycol. Due to increased production of biodiesel more glycerol has been available to a lower price.
Matarverk för Camcoil
By our employer Camatec Industriteknik AB have we been given the assignment to continue with the previous work ?Design of strip feeder?. Our goal with this work is to come up with a design basis for a strip feeder.Functionally a strip feeder consists of two rollers which with the aid of the friction between the strip and the coating on the roller create a strip force that pulls the strip through the working progress.Demands on this project:? 10 ? 600 mm in strip width and 0,1-1 mm in strip thickness.? Minimum 30m/min in production speed.? A maximum strip force on 30-40 kN.? The cost of the strip feeder?s components is to be considered of economy and quality.The need of a strip feeder occurs when the coil doesn?t manage to feed or pull the strip before or after a working process. The strip can otherwise be exposed by a permanent yield deformation or a change in the strip material if it?s pulled trough the working process only by the on ? and of-coils.
Konstruktion och byggnation av testfixtur för 10Gbit/s transpondermoduler
This thesis for the Master of Science degree was performed at Solectron Corporation in Norrköping. The background for the thesis was a need to develop and build two test fixtures to automatize testing and adjusting of transmitter modules (TX-fixture) and receiver modules (RX-fixture) which are head devices in DWDM-systems. The basic elements for the test fixtures are: Test board, switch board and DC/DC board. The main function of the test board is to handle communication between the transmitter and receiver modules and supply voltage to these modules. The test board was insufficient and modified with a microprocessor to handle the communication between the PC and the receiver module.
Dagstidningar och damidrott : En kvantitativ innehållsanalys av genusrepresentationen på sportsidorna i Sveriges största lokala- och regionala dagstidningar
According to earlier studies, men dominates the sports pages in Swedish newspapers. The gender balance is far from equal and the purpose of this thesis is therefore to look into how Swedish local and regional newspapers covered gender in their sports pages during the year of 2013. The study also examines the news values of men?s and women?s sports, whether there are any differences compared to previous studies and whether there are any differences across the country. The study uses a quantitative content analysis and the result is based on editorial material from six randomly selected newspapers in 18 randomly selected days.
