Pålarna i Alvastra : En analys av möjliga använda huggverktyg vid byggandet av Alvastra pålbyggnad

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..

Bärförmågetillväxt i pålad friktionsjord

Piled friction soil show a set-up which is increasing with the time after installation. The cost could be reduced if the set-up had been taken into account when designing but in Sweden it is very unusual to do that. Previous studies showed that set-up can vary between 25 % and 75 % during the first 90 days after Pile installation. This showed that the effect of the phenomenon is difficult to predict. A study involving five projects have been carried out by specifying certain parameters like Pile type, method for Pile installation and test method for measure the bearing capacity in friction soils located in Sweden.

Deadwood in piles or distributed : does it make any difference to saproxylic beetles?

Piles of deadwood are often retained in forests after management to support the biodiversity ofsaproxylic organisms which depend on deadwood to survive. Any knowledge about the crucial role ofPiles as suitable habitat of saproxylic organisms compared to single distributed deadwood objects thatare around the Piles would help conservation actors to motivate more forest owners to supportsaproxylic organisms during their management. Therefore to give facts to this the saproxylic fauna ofdifferent Pile positions (up and low) was studied and compared to distributed deadwood samplesaround each Pile. Our study was focused on saproxylic beetles. Some other parameters such asdiameter, deadwood volume, Pile volume and decay stage were assessed to define any effect.

Höga hus med deformerbara fundament på pålar : Pålkrafters avvikelse visavi klassisk teori samt förskjutningar beroende av vindlast

When forces in foundation Piles are calculated according to classic theory, thefoundation are assumed to be infinitely rigid which means that the foundation will notbend. High buildings need their whole width to be stable and use the ground floorwall as a foundation. But when, for example windows are needed in the ground floorwall, the stiffness of the foundation decreases which change the forces in the Piles. Inthis report the difference of Pile forces versus classic theory has been analyzed, and ifPile forces can be calculated as in classic theory. Further on, the effects of the wallmovement were analysed and how the buildings crack safety would be affected by themovement at the ground floor.

En yteffektiv bostadsmodul

The aim is to design a module for living which is flexible in a bigger context, which could condens the city and to answer the questions: How is it possible to make a livingmodule where the compact living theme works in an everyday situation? How is it possible to make one module which is able to function in several different situations? The process in solving problem has been characterized of trial and error: design a module and learn from the mistakes and take the knowledge to the next module. This is the way I have worked until I found a good solution. As a result I can show an efficient module which has several nice values of space and that is flexible and to some part adjust for a disabled person. It can on several ways condens the city.

Självgående renslastare till sockerbetor :

Our greatest interest within crop farming is to grow sugarbeets, that?s why we want to write about something new in this sector. We heard that a new concept had come to Sweden so we wanted to find out everything about this machine. This new technique was a self-propelled cleaning loader for sugarbeets. This machine is supposed to replace a loader and a cleaning machine when the sugarbeets is going to be loaded, cleaned and delivered to the sugerbeet factory. The cleaning loader picks up the sugarbeets with rollers from the Pile, which is placed close to the road.

NIM MED EN MODULÄR MULLERTWIST

This paper explains the basis for impartial games and the classicgame Nim. Nim is complicated by a modular Muller twist and thesolution for this game is described by a simple theorem. The modularMuller twist means that at the end of each move the player selects a kand the number of sticks the next player leaves in the Pile, where thedraw is made, must be congruent with k modulo m. The number m isfixed throughout the game..

Modellering och styrning av flis till en sulfatkokare

At the Skoghall pappermill, sulphatepaper pulp is produced in a continuous digester originally from 1969. To be able to maintain a high level of production there is a need for a process with few disturbances. Variations in how well the wooden chips are packed in the digester is one form of disturbance. Today there are no available measurements on how well the chips are packed. Instead this is regarded as being constant.

Biologisk behandling av oljeförorenad jord : Abiotiska faktorers inverkan och effekter av olika uppläggningssätt på nedbrytningshastigheten.

The purpose of this report was to investigate how the abiotic factors (temperature, pH, nutrients, oxygen levels and water content) would affect the decomposition of oil-contaminated soil and how a variance in structured soil would affect the decomposition-rate. A minor field-study was made and soil where structured in five different ways (one was a default Pile and was used as a reference). The study took place over 137 days and three samples were taken (start, middle, end) and analyzed for aromatic and aliphatic compounds. The result of this study shows that there is a significant difference between all methods for the aliphatic compounds and no significant difference for the aromatic compounds. The abiotic factors that affect decomposition vary from organism to organism, depending on what type of environment it will function the best.

Vibrationsproblem i närliggande konstruktioner i samband med markarbete

Ground work like blasting, piling and excavation has always had a great influence during the planning phase of a construction project since it can cause damages on adjacent buildings and have severe economic consequences. This thesis deals with how vibrations caused by ground work influence near-by buildings and what methods geotechnicians and construction entrepreneurs use to handle these risks.The purpose of this thesis is to explain risk management in relation to ground work. In order to achieve this I have used a qualitative method by interviewing a geotechnician and a ground work contractor who possess knowledge and experience useful to this thesis. The result shows that vibrations from ground work spread through the ground as seismic waves that cause displacements and packing in the ground visible in adjacent buildings as cracks and subsidence damages. Geotechnicians study ground work vibrations by means of ground investigations and experience from previous projects in order to produce a risk analysis that entrepreneurs can use to reduce damages.

Tuftade ljudabsorbenter ? väggpaneler för rumsliga och akustiska egenskaper

It is a well-known fact that textiles and carpets have benign sound-absorbing properties. It is desirable to have quantified values of these properties ? especially for architects and interior designers. They often need to be able to giveaccount for the acoustic properties of their designs at a relatively early stage and sometimes have strict acoustic classifications imposed upon them by their contractor. A product with documented acoustic properties would aid when prescribing interior elements.The purpose of this thesis is to develop a wall-mounted panel in hand-tufted material ? aesthetically pleasing and versatile but also having documented and quantified acoustic properties.

Alla ska bli konnässörer : Individualisering, gemenskap och svettiga hästar i Levande livet 1983-1984

A part of the Swedish TV-show Levande livet that aired between 1983 and 1984 was devoted to wine. This was the first time a wine tasting was being broadcasted in Sweden. Terms as ?sweaty horse? and ?moulded Pile of leaves? ? that the wine connoisseurs Carl Jan Granqvist and Knut-Christian Gröntoft used to describe the wines ? became objects of both appreciation and ridicule. Their way of talking about wine reminds of Robert Parker?s wine language, which grew of importance from the 1970s and onwards.                      The purpose of this thesis is to try to write a history of taste.

TOMO Hugglink

Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the Pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

Dimensionering av grundläggning med hjälp av Eurokod

AbstractWork to develop the Eurocodes started in 1975 by the European Commission adopted a program to eliminate trade barriers within the construction area. The goal was to create common European design standards that would replace the member countries' own rules. Eurocodes will replace The National Board of Housing Building and Planning, National Rail, The National Road Administration and other agencies' calculation rules for the buildings structures. The transition to the use of Eurocodes looks like this:Eurocodes set to Swedish standards  between 2002 ? 2007They can be used parallel with national standards 2006 - 2009 The total transition is at the end of 2010/2011.Right now is going on a lot of work for replacement of the existing standards to Eurocodes.  The transition to the new calculations` standards, many construction companies and consulting firms facing a big changes and competitions.

Modellering av flisstack

Bioenergi är en stor industri i Sverige och står för en betydande del av energiomsättningen. Bioenergi i form av flis förvaras runt om i landet på hög i väntan på förbränning. Då högarna läggs upp startar olika processer som värmer upp stacken, ofta till temperaturer på 50°C under det första dygnet. En vanlig ansats i litteraturen är att denna temperaturstegring beror på aerob nedbrytning. Arbetet ämnar undersöka om denna uppvärmning endast beror av mikrobiella aktiviteter.
