Populationsstruktur och genetisk analys av exteriöra egenskaper hos svensk ardenner :

The purposes of this study were to estimate genetic and phenotypic parameters for conformation traits in Swedish Ardenner, a heavy draught horse, and to investigate the inbreeding status of the population. Additionally, a breeding scheme proposal was created, based on the results achieved in the study. The data studied were obtained from the Swedish Horse Board and from the Swedish Ardenner Association. The data included 1632 three-year-old horses, mainly mares, and 356 stallions, judged between 1986 and 2005 at conformation shows. The traits studied were type, head-neck-body, legs, walk and trot at hand, total score and height at withers.

Räfstens vår : Skillnader och likheter i rannsakning och bestraffning ur ett genusperspektiv under ärkebiskop Angermannus visitationsresa våren 1596

The aim of this study was to investigate and analyze similarities and differences in trials and punishment from a gender perspective, during the inquisition in the episcopate of Linköping. A inquisition initiated by duke Karl but performed by archbishop Abraham Angermannus in the year 1596.During the working process a quantitive method was used in the purpose of getting statistic data considering number of men and women that were trialed and punished. A hermeneutic qualitive method was also used in the purpose of closer investigating certain cases that men and women were involved in. The theoretical concepts that have been of importance and used in this study are the individual and the female subject that is based on gender in judicial procedures.The results showed that 49 % of the men were trialed for quarrel. Not as many men were trialed for contempt towards the church and witchery.The most frequently used corporal punishment in this cases were flogging that were executed for totally 38 % of the men.The investigation also proved that men were punished with these forms of corporal punishments for showing their contempt towards the church.

Rimbo våtmark : en förstudie på förväntad kväveavskiljning och lämplig växtlighet

This study was made as a part of a feasibility study on a polishing wetland at Rimbo wastewater plant (wwp) in Norrtälje municipality. The wwp had to decrease the nitrogen discharge to reach the limit 15 mg tot-N/l. The nitrogen in the outlet was mainly in the form of nitrate, hence the wetland mainly ought to support denitrification. The proposed area for the wetland was situated right next to the wwp and was already in the municipalitys posession. One aim of this study was to examine what spieces of plants needed to achieve highest possible denitrification.

Aktivitet, läggnings- och resningsbeteenden, tillväxt samt renlighet hos kvigor i liggbås respektive djupströbäddsbox :

The aim of this study was to compare activity, lying down and getting up behaviour, weight gain and cleanliness in heifers in cubicles versus on deep-litter. The study was conducted from autumn of 2005 until autumn of 2006 in a commercial organic dairy herd with 340 cows. In 2005 the farm rebuilt half of the young stock accommodation from deep-litter pens to cubicles. The experiment used 150 heifers of the breeds Swedish Red, Swedish Holstein and crossbreeds between these, all born on the farm. The animals were divided into three blocks based on breed and within each block they were sorted after increasing age. The youngest heifer in each block was randomly allocated to one of two groups, cubicle or deep-litter pen.

Spårelement i Sveriges jordbruksmark : flöden, trender och fältbalanser

Field balances based on supply and removal of trace elements from the topsoil have been calculatedfor farms specialized in crop, dairy and pig production in Sweden. Today's field balances have beencompared with the field balances of 1990 in order to examine if, and then how, the situation haschanged. Studied trace elements are arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu),mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn).The balance calculations show that the stores of Cu and Zn are depleted with an average rate of -15% and -6 % over a 100-years period on crop farms when only commercial fertilizers are being used.The concentrations of Hg and Pb tend to increase in the topsoil on crop farms with more than 3 % forHg and with 2 % for Pb in 100 years. There is today balance between supply and removal of the traceelements As, Cd, Cr, Mn and Ni. In the south of Sweden, on crop farms with sugar beets in the croprotation, one can see a decrease in the concentration of Cd in the top soil by -6 % over a period of100 years.

Lagerstyrning vid Frigoscandia Freezer AB

Frigoscandia Freezer AB have seen themselves as an entrepreneur company for a long time, but have lately begun to realise that they have to go against a more administrative era. With that insight they have begun to examine their enterprise in order to achieve this. The division Team Spare Parts has started a project with the intention of checking-up the inventory management, and improving it for the future. To get support for this and other point of views, they decided to let us do our exam thesis as a part of the project.The first part of the thesis deals with the appropriate inventory theory. All calculations in the other parts of the thesis have been based upon this.

Från ståtlig befästning till vittrande världsarv : En jämförelse av byggnadstekniska metoder för sammanbindning av skalmurar

This is a final year project considering constructional techniques for joining cavity walls. The project is related to an ongoing scientific programme about the restoration of The City wall of Visby located on Gotland. The programme was set by Riksantikvarieämbetet as a reaction to a collapse of the outer masonry wall shell which took place in February 2012.The City wall of Visby is a medieval fortification built out of limestone during the 13th century. The wall is constructed as a cavity wall with two separate masonry shells connected to each other through an intermediate core. During the 14th century the wall was heightened which lead to a higher stress, especially in the outer wall face.

Implementering av lean i ett gjuteri med låga volymer och hög variation

Valmets own foundry in Karlstad has during a long period of time had problems being profitable. The goal today is to turn this around. Today there are three different productionlines; engine blocks, Yankeecylinders and components for the wind turbine industry. This master thesis has focused on examining if value stream mapping is a useful tool to use in a foundry, and therefore outside the typical manufacturing industry. The target has also been to evaluate if there is a possibility to improve the flow in the foundry and also the results.During the 20 weeks this work has been done at the foundry data has been collected and analyzed.

Urban vindkraft : Vindkraftsprojekt Järvafältet & vindkraft i Sverige

Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.

Leanorienterad flödesutveckling : av kärntillverkningen på Affärsenhet Cylinder ASSA AB

Business unit Cylinder at ASSA AB in Eskilstuna are having problem with frictions in their production process. Changes are occurring and older products along with machineries are phased out and transferred to low-cost countries. This opens up possibilities to at a larger extend customize physical flows after production flows. The authors where given the task to analyze the production and find problem areas to improve and to give suggestion on how Business unit Cylinder can work to optimize their production flow.The aim of the thesis work is to come up with suggestions on how to reduce the lead time in production and how the tied up capital can be reduced. In more detail the task included to find problem areas that are counteracting an effective flow, give solutions on new flows for the production of the cylinder core, give suggestions for new stock points for the production and how the production shall be managed and controlled.During the last twelve months ASSA AB has sold over 700 different types of cylinder cores, and the product range is very wide.

Energieffektivisering i ett reningsverk för skogsindustriellt avloppsvatten genom förfällning av extraktivämnen

Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.

Beräkningsmodul för ett förbättrat offertförfarande och minskad icke-värdeskapande tid

In early January 2010 the authors participated in a meeting with the chief engineer for a company in which a central part is manufacturing of printed circuit boards (PCB). At this meeting it emerged that the machinery and production methods have changed substantially since the early 1990's. The spreadsheet for preliminary production time calculations by the company is today based on conditions from almost 20 years ago. The company has over the years been trying to adjust the spreadsheet template. The result of these adjustments has filled it with historical residue, something which makes the template difficult and time consuming when the primary user tries to handle it.The purpose of this study was to help the company increase its accuracy in the representation of the production times for the different PCB-based products by developing a new costing model based on an already existing but inadequate spreadsheet template. The company also expressed the wish that the new costing model would be less time consuming to work with.The methods used to achieve the goal are interviewing, participatory observations and meetings with relevant persons. The data obtained were analyzed using the theory on PCB production and visualization of data.

Skötsel av älgskadade bestånd :

Sweden has today the highest moose (Alces alces) population in the world. The population has been very high since the late seventies and in the beginning of the eighties there was a big ?moose explosion?. The main food source for moose during the winter is young pine (Pinus sylvestris) and birch (Betula spp.). The high moose population has therefore lead to high damage on pine forests over big areas.

Effektivisering av kylsystem på Utö värdshus

Energy consumption is at present a major political issue, and numerous projects that comprise many nations are currently in process to increase energy efficiency and bring down energy dependency. As a member state of the EU, Sweden now faces the challenge of implementing substantial energy-saving measures until the year 2016. One of these measures is the project ?Green Islands? financed by the EU that intend on creating sustainable islands in areas around the Baltic Sea. The Archipelago Foundation leads the project that concerns the Stockholm archipelago, where focus has been placed upon decreasing energy usage in businesses and services on Utö among other islands.

Utvärdering av fjädrande statorfötter : Nytt koncept i vattenkraftgeneratorer

This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.
