Amyloid beta inducerad klyvning av NG2 medierad via LRP-1 receptorn
Bakgrund: Deposition av fibrillär amyloid beta 1-42 (A?) i hjärnan är ett välkänt kännetecken för den neurodegenerativa sjukdomen Alzheimer?s (AD). Dessa ansamlingar påverkar pericyter, en celltyp involverad i blodkärlsfunktion och upprätthållande av blodhjärnbarriären (BBB). Pericyter uttrycker både receptorn low density lipoprotein receptor related protein 1 (LRP-1) till vilken A?1-42 binder, och proteoglykanet NG2.
Sorterar skotaren bort det timmer som skördaren har tillrett? :
The efficiency of the harvesters work is more often reviewed, than the work of the forwarders. In a local Stora Enso office the differences between the harvesters reported volume of timber, and the actual volume delivered to the industry had been noticed. Therefore, the decision was made to do a review on the forwarders work.
The review was conducted together with a worker from Vmf Qbera, who is working daily with wood measurement, in order to get a valid evaluation of the logs. Eight sites were included in the survey, and on each site 50 logs were marked. Approximately one third of the marked logs were pulpwood, and the remaining logs marked were timber.

The result was a prototype made out of a bed frame and 18 pair of jeans and with details made out of leather..
Effekter av gödsling i äldre tallbestånd på renbetesväxter i fält- och bottenskikt :
Reindeer husbandry and Forestry are both area related industries and will in big extent use the same lands. Conflicts often arise because of that the industries have different interests. Many of the activities done by the forestry influences the reindeer husbandry in an undesirable way, simultaneously as the reindeer husbandry activities can have negative consequences for the forestry. One such forestry activity is fertilization.
It was during the 1960´s forest fertilization began to be practiced and the reason was that the increase in growth that the fertilization gave could be able to cover for the future shortage in wood many feared.
During the 1970´s when the fertilizing activities were most intensive about 200 000 ha was fertilized annually.
Femtio Nyanser av Co-branding - En kvantitativ studie om effekterna av co-branding på konsumenters varumärkes- och produktutvärdering beroende av kvalitetssegment och hedoniska shoppingmotivationer
The retailing industry has an extremely high density of brands. In order to differentiate its offer, both retailers and suppliers, are constantly forced to come up with new ways to launch their products. A collaborative strategy between two brands is called co-branding, which means that both the private label and the supplier's brand are displayed on the new product packaging. Several studies have shown that a co-branding strategy is successful, but many operators are still reluctant to use co-branding in fear of long-term losses due to potentially damaged business relations. The objective of this study is to explain how the product- and brand related value for customers, retailers and suppliers is affected by co-branding between private labels and national brands.
Brandrelaterade insekters lokala artrikedom i förhållande till olika miljövariabler : Fokus på betydelsen av konnektivitet på brandfält i boreal skog i Västerbottens län
The last century, forest fires have decreased in frequency due to efficient fire-suppression along with the growth of the industrial forestry. Since 1990, fire has been reintroduced under controlled forms to recreate burnt habitats. Many species that are dependent on, or benefits from, forest fires have increased since fire was reintroduced. The importance of connectivity is often addressed in ecological research. This is particularly important for species dependent on short-lived habitats such as burnt forests.
Kraftvärmeverk i glesbygd - en möjlighet?
Our purpose in this paper is to examine if there is any profitability for a company with a factory in the timber industry to invest in a combined heat and power, CHP. Based on analysis and the results that the paper generates, we will give Derome AB a suggestion on how it is a profitable investment or not to installing in a CHP.By investing in a CHP plant, you can get a high efficiency, which means that companies can use their resources more effectively. The Swedish wood industry has by-products of production that can be used for combustion in their boiler which is an advantage.The essay is a qualitative study where we have a case company, Derome AB. In this company, we interviewed two employees who have knowledge in the study. They have helped us to provide information and data about their business.We chose to use the pay-off- and the net present value method, NPV, to see if there are profitable advantages for the investment.
Den gemensamma utrikes och säkerhetspolitiken- Ett neo-funktionalistiskt perspektiv
This essay aims to explore the development of the common foreign and security policy within the European Union as well as the recent addition of the post of High representative in the field of the common foreign and security policy. This essay will attempt to achieve this trough exploring the questions; how have the aim of the European foreign policy developed, how the forms of cooperation has within this field developed and finally what impact will the recent addition of a high representative for the common foreign and security have. My aim is to answer these questions with the help of neo-functionalism.The results that came out of this essay point to the direction that the neo- functionalist premise about spill over effects and the notion about increased supranational influence turn out to have some validity in them. The study has shown that during the time the cooperation within the field of foreign and security policy have developed it is possible to see that supranational institutions will gain influence when the scope of integration within a policy area widens and deepens..
Dimensionering av industrilager för biobränsle :
The aim of this study was to develop a simple model for calculating stock costs for bio fuel at Billerud Karlsborg and subsequently recommending a suitable stock level of bio fuel. The stock components considered in the model are GROT (branches and tops), bark, dry wood chips, raw wood chips from barking and sawdust. The calculations are based on a probability distribution of historical deviations between ordered and delivered volumes. The model presents two different ways to manage the supply in case of irregular deliveries. The first way is to stock enough volume to cover the deviations and the second way is to compensate with a quick purchase from the spot market (at extra high purchase prices).
Undersökning av deponerat ferrokromstoft : Utvärdering av ny behandlingsmetod
The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.

Jag kan själv : Spelmanualer för mellanstadiebarn
Todays board game manuals have many shortcomings. One of them is that they are not always adapted to the game's target audience.Adapting the language and shape of a game manual for the the target group children, can save time for both parents and teachers, and give the children a chance to conquer the game by themselves. In addition, playing board games can lead to children developing other important properties such as problem solving and independence.This study found that the game manuals inconsistency, tone and the way they adress the reader makes it difficult for children to grasp the content. Many game manuals do not speak directly to the reader, and often describes gameplay in a passive way, which has been shown by this study.This study has resulted in 12 guidelines for writing game manuals for children. In addition, they have been tested with a sample study.
Analys av framtida potential för virkesköp från privata skogsägare i Västerbottens län : beslutsunderlag för virkesköpsstrategier
This study was conducted on behalf of SCA forest AB, Västerbottens forest administration. Timber procurement from non-industrial private forest owners has become an increasingly important part of SCA:s wood supply. The objectives of this study was to report the current forest conditions in the private forests in the county of Västerbotten, analyse the potential for procurement of wood from private forest owners, and provide a basis for decisions on future strategies for timber procurement from private owners.Material and data have been collected from different sources, mainly from Swedish National Forest Inventory and SKA-VB08. This material was the basis for the analysis and calculations performed with the Heureka application PlanWise. This study area was divided into six different analytical areas (Coastal south, Coastal middle, Lycksele, Inland south, Inland north, Skellefteå), where each area of analysis is represented by a number of municipalities.In this study, two scenarios were specified; one describing the current forest management with current harvesting levels and the effects of these assumptions, the second to illuminate what potential there is for future timber harvesting.
Marknadsundersökning om markägarens val av skogspartner
The driving forces from the forest owners point-of-view was studied on a market where several buyers attend to procure round-wood. It was concluded that forest owners prefer personal contacts to other means of communication, but that it is essential that the initial contact is a personal letter on paper. Furthermore, although price is always important, long standing relations is asked for. The buying companies need skillful experienced buyers that can provide more than just quick closures of deals..
