Modulär Mekanikstruktur för Nanosatelliter

The objective of this thesis was to present a design proposal on a modular mechanicalstructure for a nanosatellite. The size of the structure should follow the CubeSatstandards. This standard divides satellites in units (U), where 1U is equivalent to acube where sides measure 100 mm. 2U corresponds to the same volume and size as2 assembled 1U structures, and so on. The focus was to develop a structure in theorder of 3U and 6U.At the integration in the satellite launch rocket, there are a couple of differentinterfaces, where the structure is adapted to common ones; P-POD and CSD.

Kvalitet i brödvete :

The quality of bread wheat is a large subject to study. The quality rests on two legs. The first one is the inheritance of specific characters, which can be influenced through plant breeding and type of cultivar. The other one is the environmental influences, such as crop rotation, nutrition, harvest and storage. The latter factors are possibly to affect through cultivation practices, while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content.

Nautisk turism : en jämförelse mellan svenska och kroatiska förhållanden

AbstractA tourism genre that has developed in recent years is the nautical tourism, nautical tourism is described as a tourism genre that includes all activities in relation to water. Croatia is one country that has invested in and has good presumption for this type of tourism, and has also received an international recognition as a top destination within the nautical tourism genre. The purpose with this thesis is to increase knowledge about the nautical tourism development in Croatia, and to see if it would be possible to develop on Swedish conditions. Sweden is a destination with a large number of archipelagos, located in both inland lakes and along coastal areas. Stockholm archipelago is one of the world's largest archipelagos which has a long tradition as a tourist destination.

Gårdsbaserade system för spannmålshantering i den framtida Lantmännenorganisationen :

The Swedish cooperative Lantmännen Ekonomiska Förening has initiated a project labelled "Operation Blåljus" that includes an extensive program for closing down elevators. The number of elevators will be reduced from 92 to approximately 15 after harvest of 2007. The objective of Blåljus is to increase the price of grain with 10 öre/kg. A project has been initiated at the Lantmännen Grain division where the purpose is to provide the farmers with support in their decisions and practical advice how they can load a 35 ton grain truck on 30 minutes. The result from the project will serve as a support system to the farmer in his ambition to achieve cost efficient systems to load a truck with grain on the farm.

Kvalificerade bedömningar av värdeförändringar i byggd miljö

På uppdrag av SWECO Management AB utreds möjligheten till att kunna se korrelationer mellan åtgärder på en fastighet eller i dess omgivning och ett förändrat fastighetsvärde. Denna information skall vara SWECO till gagn i upphandlingssituationer, för att lättare kunna visa för beställaren om att tjänsten i fråga kan leda till ett ökat fastighetsvärde. Med utgångspunkt i den begränsade litteraturen, har information främst samlats genom en intervjuprocess med representanter från fastighetsbranschen. För att få ett brett perspektiv i ämnet, har representanter med olika befattningar, olika lång erfarenhet och med varierande utbildningar intervjuats. I studien görs avgränsningar om makrofaktorer, såsom konjunktursvängningar, ränteförändringar, finanskriser, låneinstitutens förändrade låneregler etc.

SecRePac - Strimlare för hushållsförpackningar

SecRePac is a household appliance that simplifies sorting of packaging such as milk, juice and yogurt containers. By shredding the packages SecRePac reduces its volume uptake both in the home and at the recycling station. This leads to minimization of both transports to the recycling stations and truck transport for emptying the containers at the recycling station.The greenhouse effect deteriorates and becomes worse and worse leading to extreme climate changes and natural disasters such as floods as an example. Carbon dioxide emissions are the major reason for this and at least 30 percent of all these emissions come directly from transports. In the EU carbon emissions has decreased in the past few years.

TaqMan® Sample-to-SNP Kit? : evaluation of kit for low-cost and fast preparing of DNA-samples before genotype analysis

 Genotyping can be used to link genetic variation among individuals to certain diseases or conditions. Some known disorders and states that are dependent on single nucleotide polymorphism (SNPs) are lactose intolerance, venous thrombosis, hereditary hemochromatosis and the difference in sensibility among people to metabolise drugs.In this project a new kit, TaqManÒ Sample-to-SNP KitÔ for extraction of DNA and preparation of the extract for genotyping with real-time PCR and allelic discrimination, was evaluated. QIAamp® DNA Blood Biorobot® MDx Kit was used as the reference method.The purpose of the comparison was to find a method that makes DNA extraction from blood samples cheaper and faster, but with the same reliability as the reference procedure.The results of the evaluation showed a complete agreement of the genotype results between the methods tested, which means that the new method was as reliable as the reference method. The costs of reagents and material would be reduced with 52% if the new method is adopted, that alone would result in a cost reduction of 144 000SEK a year with a sample volume of 650 samples/month. The time for DNA extraction would also be reduced with the new procedure. .

Produktivitetseffekter av flerträdshantering

The main purpose of this study is to investigate the productivity effects of multiple tree handling in thinnings. Other important elements have been to investigate in which extent multi-tree handling is used in stands with different stem volumes and the impact of collecting partially delimbed fuelwood assortments has on harvesting performance. The study is based on data from thinnings in Sydved and contractors' operating activities. Collection and compilation of operating schedules, number of stems and surveyed volumes from several contractors and a large number of executed orders underlying the results. Multiple tree handling is used to a much greater extent at lower average stem volumes. Prediction models for productivity of the multiple-tree handling harvesters in the study differ from the productivity models for single-tree handling. In the model developed in this study productivity is not as dependent of stem volume as reference models.

Statliga turistbyråers marknadskommunikation : en jämförande studie om den Tyska och den Tjeckiska turistbyråns verksamhet på den svenska marknaden

In many of the world's countries, there is a national organization responsible for marketingthat country as a tourist destination. Through their offices, these organizations work towardsthe creation of effective strategies and a deeper understanding of local markets. Usingqualitative methods such as interviews, observations, and thematic analysis, we managed toinvestigate how the Czech and the German national tourist offices operate, and whatstrategies they are implementing to increase the volume of tourism. The study focused on theanalysis and comparison of the organizations' goals and communication channels.The results show that the investigated tourist boards operate in a similar manner with smalldifferences concerning choice of strategies and communication channels. These discrepanciescan be partly explained by differences in the organization's ownership forms and theconsequences that follow that fact.

Förtolkning inför skogsbruksplanläggning med laserdata (NNH), eller traditionell flygbildstolkning?

The purpose of this study was to investigate produced laser data from the new national height model's airborne laser scanning in Sweden, what quality it has and whether it can be used for forest management planning. From airborne laser scanning one can obtain information on forest variables such as tree species, height, diameter and basal area. Norra skogsägarna is the principal employer of this project and they wanted know to the quality of the laser data which needs to cope with their standards. If the laser data the quality required it can replace some of the operations performed by field planners. To examine the quality of the produced laser data a control tax assessment has been performed in 30 forest departments. This was done in an objective manner.

Öppna problem i läroböcker för kurs Matematik A

The purpose of this essay is to investigate the presences of open-ended problems in the textbooks of high school Mathematics A. For practical reasons the study was limited to three textbooks and two topics, Fractions and Area & Volume. The Essay also describes the theory behind open-ended problems and why they should be used. I identify three criteria as a definition for open-ended problems. The study found that only 7,6% of the investigated tasks qualified, and met at least 1 criterion.

Sitkagranens potentiella merproduktion jämfört med vanlig gran i Hallands län

Sitka spruce (Picea sitchensis) is not considered to be a native species to Swedish forests. It´s origin is the pacific coast of Northern America, an area that is dominated by a coastal climate which makes it likely to believe that it would be well suited for growing in the south-west of Sweden. This study aims to investigate the gain in production that can be reached by growing sitka spruce instead of Norway spruce (Picea abies) in the county of Halland. A regression model based on data from forest experiments was produced to explain the gain in production. This model was based on elevation and annual precipitation. The model was then used to create a map layer in arcGIS that shows the gain of volume in comparison to Norway spruce in percent. An analysis was carried out to find what share of the forestland in Halland county that fell into four different classes of production gain.

Inverkan av olika joner och jonconcentrationer på porstorleksfördelningen i trämassa-fibrer

The basic ingredient of paper is the individual wood fibers. The property of the fibers depends on a variety of factors e.g., method of pulp production and processing. The final sheet quality depends in part on how the fibers interface between each other and therefore factors that affect the fiber size are of interest.The flexibility of the fibers depends in part on the pore water i.e., the fiber swelling. The sheet becomes less flexible at low water content which gives a loss in strength. Thus it becomes desirable to increase the water uptake.The experimental investigation described in this report consists of exposing the wood fibers to different ions and ionic strength and then measure the pore size by thermoporosimetry where a DSC (Differential Scanning Calorimeter) is used.

Medveten måltid : Ett begrepp i förändring

The key elements of sourdough fermentation are the presence of active lactic acid bacteria (LAB) and yeast. Sourdough fermentation originates from the ancient Egypt. One theory concerning its onset states that a portion of bread dough was set aside to be baked at a later date and started to ferment spontaneously.Sourdough may contain a wide variety of microorganisms, mainly dominated by LAB and yeast. There are over 50 species of LAB that has been identified in various sourdoughs and more than 20 species of yeast. Sourdough fermentation has been shown to have various impacts on baked cereal good, most of which are attributed to LAB.This study addresses some effects of LAB from fermented milk products in sourdough and sourdough bread.
