This paper deals with the question of with witch tools the Alvastra pile dwelling was built. To reach a result I calculate the curvature on 29 stone axes, 8 double-edged axes and 21 simple-edged axes, used in the middle-neolithic in what today is Sweden. These results are then compared with two jams (the point in the pole where the axes edged stopped and left a mark) on two piles from Alvastra pile dwelling..

Shanghai Waigaoqiao Free Trade Zone är geografiskt utmärkt placerad vid bedrivande av handel och utgör idag en internationell hub. Området har också tillgång till en god infrastruktur som ständigt förbättras. Waigaoqiao erbjuder sakkunniga konsulter och har ett starkt styrelsestöd. I framtiden då Free Trade Zones inte kommer att vara det enda valet för svenska företag som vill etablera sig i Kina, utan att behöva ingå joint ventures eller liknande avtal, kommer Waigaoqiaos handelsbefrämjande miljö att vara avgörande vid ett etableringsval i just det området. De skattefördelar och tullfördelar som idag existerar i Waigaoqiao kommer att försvinna när Kinas WTO-avtal i sin helhet träder i kraft.

The Savi?s Warbler (Locustella luscinioides) is a recently established bird species in a few reedy shallow lakes of southern Sweden and has only been found nesting for the last twenty years. Little is known about the species' habitat preferences, breeding biology and demands for specific territory structures at breeding sites in Sweden. Knowledge of a newly established species? habitat requirements is essential to maintain a viable population and design action plans.

The aim of this study is to elucidate factors that effect growth of Sarcina lutea and Bacillus subtilis, exposed to the growth inhibitor SDS (Sodiumdodecylsulfat). Agar diffusion experiments revealed repeated, concentric zones of inhibition and stimulation upon exposure to Sodiumdodecylsulphate or to Amoxicillin. Temperature, nutrient concentration and inhibitor concentration were controlled. Formation of successively repeated zones of inhibition, stimulation, inhibition and stimulation is discussed: ? The extension of the primary inhibition zone is due to the concentration of applied Sodium dodecyl sulphate.? Immediately outside the primary inhibition zone the bacteria have access to diffusing nutrients that have not been consumed in the primary inhabitation zone.? In zones of dense bacterial growth the bacteria may produce inhibiting substances, affecting growth of bacteria in adjacent zones.? In zones of dense bacterial growth the nutrients will soon become depleted, thus affecting bacteria in adjacent zones..

Difficult calvings and stillborn calves are costly for the producer and lowering these frequencies can decrease the costs for the dairy operation. Each calving in the herd is registered by the farmer and stored in a central database. The information is used to monitor the level of calving-difficulties and stillborn calves in the herd and nationally. Monitoring of these registrations is important to detect possible changes. Breeding-value prediction for calving traits is based on the calving information in the database.

One of ABB Power Systems´s business areas is HVDC (High Voltage Direct Current) technology. HVDC is used for transmissions for both short and long distances. One of Power Systems?s products is called HVDC Light. HVDC Light is a relatively new technology for power transmission, but have before only been used for motor drives applications.

The purpose of this paper is to standardize and simplify the design work on a few specific types of storage brackets for balconies. The company Balco AB had the wish to simplify the design work in the preparation of attachments to their balcony structures. This would be done by a calculation matrix that could be produced which then in turn could be used for each new project by the company. The design work behind the development of these fittings at each new project is costly both in terms of time devoted by each calculation but also the cost of the time. The purpose of this report is that in a systematic manner, a calculation matrix can be created that then the company instead may follow from each new project.In carrying out the project used HILTI calculation program, which was provided by the company HILTI.

Research concerning movement patterns of wild animals has been advancing since GPS technology arrived. But studying the snow leopard (Panthera uncia) is still difficult because of the harsh territory it inhabits in Central Asia. This study took place in south Gobi, Mongolia, and aimed to estimate the time spent at kills and the maximum distance away from kills between visits. Snow leopards were monitored with GPS collars that took a location every five or seven hours. Potential kill sites were established by identifying clusters of GPS-locations in ArcGIS and visited in the field for confirmation.

Over the past 40 years 600 000 ha of lodgepole pine (Pinus contorta ssp. latifolia (Engelm.) Critchf.) has been planted in Sweden (280 000 ha on SCA's forest land alone which represents about 15% of the company's total forest land area). In the early 70's SCA situated a number of experimental stands in order to investigate different aspects of the exotic tree, primarily growth rate. To be able to compare the two species plots with scots pine (Pinus sylvestris L.), this species was also planted at the same time and under the same conditions. A number of questions should always be raised when exotic species are introduced in an ecosystem. Invasiveness, the pathogen situation and purely ethical issues should be discussed.

The last decades the populations of wild boar (Sus scrofa) has increased rapidly over the species? entire European range, including Sweden. This is followed by increasing human-wildlife conflicts as a result of the wild boar foraging behavior, causing damage to agricultural crop fields due to trampling and feeding. To be able to minimize damage we need more knowledge of where in the fields the risk of damage is high and what features in the landscape that affect this risk. I analyzed damage distribution in relation to the distance to six different landscape features; forest, road, ditch, building, game field and bait station, in the study area, the Island Mörkö in eastern central Sweden.

Under hösten 2008 gjordes ett examensarbete om utvecklingen av luftrenare på ett företag vidnamn AD Air Design AB (AD) beläget i Åkersberga utanför Stockholm. Examensarbetetdelades i två delar där den första delen behandlade dokumentation av en existerande modell.Bakgrunden för det var en licensförsäljning från AD till Humanscale i USA för nyttjandet avDEP (Disposable Electrostatical Precipitators) luftreningsteknik, men Humanscalemisslyckades i sin produktutveckling med tekniken. AD tog därför fram en fungerande modellåt dem men ritningsunderlag saknades. Syftet med att ta fram ritningsunderlaget var förprojektgruppen att fördjupa kunskapen om hur luftreningen fungerade för AD:s maskinerinför examensarbetets del 2.AD:s företagsidé är utveckling av luftrenare med en speciell elektrofilterteknik kallad DEP.Tekniken bygger på det revolutionerade sättet att tillverka en filterkassett av papper till ettelektrofilter där partiklar fångas i filtret när de laddas med hjälp av en coronaström från enborste. Den existerande modellen innehöll denna teknik och dess delar måttades upp.

The wide distribution range of our boreal pine (Pinus sylvestris L.) provides a great variation in growing conditions and climate/weather factors that influence the wood development of the trees. A great number of extensive studies have been conducted over the years in order to clarify growth trends of this and other species over more or less wide-ranging areas. In this thesis effects of weather factors were instead compared between different forest stands from the about same geographical location. The effects of precipitation, temperature and frost on the year ring characteristics of pine were studied in the research forest of Svartberget Vindeln, in northern Sweden. The stands differed in site index and silvicultural treatment; fertile ? high stem density, fertile ? low stem density, poor ? high stem density and poor ? low stem density.

This report describes a project carried out in cooperation with Klippan Safety AB. The purpose of this project has been to develop a product that facilitates the living area in a truck cabin for the customers. To be able to develop, in a structured way, that kind of product, the project has been based on different product development theories. The project contained of following parts: marketing research, product generation, product evaluation and prototyping. After information from the marketing research and discussions with the company, the decision was made that the task was going to consist an improvement of the existing product referred to as 'the comfort module'.

Denna studie berör olika developer zones som idag drivs av företag i Sverige, och om hur dessa är uppbyggda. Den tar upp de problem som dessa företag har stött på, samt vad man ska tänka på vid uppstart och användning av en developer zone.Att låta sin developer zone vara helt öppen eller helt stängd är inte det mest optimala sättet eftersom man i den helt öppna versionen låter sin information vara tillgänglig för allt och alla. Den helt stängda versionen stänger ute kunskap från developer zonen. Genom att sätta upp en developer zone med båda delarna, dvs. en öppen del för utvecklare som intresserade att utveckla innovativa tjänster/produkter och en stängd del för företag som tillsammans med ägaren av developer zonen har ett ekonomiskt intresse, så uppnår man en mer kontrollerad form.
