Buskröjning längs skogsbilvägar : en produktivitetsstudie av två kättingslagor

To regularly remove woody vegetation along the roadside of forest roads is an important part of the road maintenance, since the vegetation binds moisture in the road side and, thus, the removal makes the road drying faster with results in improved bearing capacity. Vegetation removal also makes it easier to upgrade the road by material recycling from the ditch and, moreover, the visibility along the road is maintained.The aim of the study was to evaluate what type of chain flail is the best and most cost-effective for removal of different kind of woody vegetation along forest roadsides.Time studies were made on two chain flails when removing woody vegetation in three different classes; easy-, middle- and heavy shrub removal. The studied flails were one light and rather simple flail named Optimal M160 and a heavier and more advanced flail named Slagkraft H210. The removal was made according to Holmen Skogs? specification and the quality of the cleaning was measured by objective belt inventory.The productivity was higher with the heavy flail within all cleaning classes.

In this study we have investigated the procedures of change with the aim of identifying which pedagogical processes in work procedures that enables organizational learning. Furthermore, the study aimed at gaining insight of how the work procedures enable organizational learning in a learning organization. We have utilized case study tradition to examine specific occurrences in their natural environment to thereby understand the matter of investigation.

Röjningsbenägenheten bland privata skogsägare : en enkätundersökning bland medlemmar i SÖDRA

The intensity of cleaning declined dramatically in the early 1990?s in the Swedish forests. Recession, an economic depressed forestry and the new law of silviculture from 1993, where the duty of cleaning was removed have been considered as sources to the decline. This has led to a situation where huge areas of forests are untouched, which can lead to negative effects for those stands in the future. The purpose of this thesis was to find out how the individual landowner acts and feel when it concerns cleaning activities. Has the landowner noticed Södra?s campaigns about cleaning and what sort of measure should Södra implement to increase the members? cleaning activity? The thesis is based on a opinion poll made through a random draw among all Södra?s members.

Biologisk reducering av nitrat och nitrit i vatten

During the summer 2007 was a scrubber tested at Gruvön papper mill in Grums. The scrubber reduced NOx with 90 % in flue gas. NOx was transferred from the flue gas to a scrubber liquid as nitrate and nitrite. The scrubber liquid needs to be purified from nitrate and nitrite. One possible solution is to clean the scrubber liquid in Gruvön biologic cleaning construction.Microorganisms in the biologic cleaning construction need to assimilate nitrogen. There are environments free from oxygen in the cleaning construction.

Prestations- och kvalitetsstudie av maskiner för rensning av skogsdiken

Ditch cleaning is increasingly important in Swedish forestry. This study compare different concepts concerning machinery, namely two general-purpose excavators of different sizes, 8 tonnes and 15 tonnes, versus a dedicated machine constructed solely to deal with ditch-cleaning. The machines were tested on rough as well as on gentle terrain and on open terrain as well as in young stands in connection with thinning. The conclusions were that the excavators are more versatile and have greater capacity than the dedicated machine, while the latter excels in quality of work. Interestingly, there was no significant difference in performance between the both excavators..

Frystorkning Kontrollerad torkning av kulturhistorisk dräkt?

Cultural objects may become wet by deliberate water cleaning, water disaster or watersoaked for other reasons. Air drying textile objects and even other organic materials from awater wet state, involves many problems depending on the strong capillarity action of water.Damages and changes such as bleeding of dyes, stains or lines of impurities from watermovement, shrinking or stiffness can occur. Freeze-drying as an alternative drying methodhas often been used for wet archaeological and marine objects, but more seldom for historicalmaterials.This bachelor thesis addresses the issue of whether freeze-drying can be an alternative controlleddrying method for historic costumes. Costumes and related objects are often compositeobjects, consisting of multiple materials, as well as being three dimensional, all of whichwill complicate drying. The purpose of this study was to investigate whether it is possible tohandle costume objects after wet cleaning for drying by freeze-drying, and if damages due tosurface tension of water, can be avoided in this way.

Detonerad Demokrati : Den demokratiska freden i Irak, en möjlighet att börja om

The swedish law against female genital mutilation (FGM) prohibits procedures that removes parts of the female genitalia and thereby makes permanent changes in the body. The problem with the wording of the law is that it may also apply to the western phenomenon cosmetic genital surgery. This paper therefore examines if cosmetic genital surgery should be covered by the swedish law against FGM, by making a critical comparing analysis. The paper begins with comparing FGM with cosmetic genital surgery to prove that there are more similarities than differences between the procedures. By using the theoretical perspectives universalism and postcolonialism, the paper then examines why, particularly in the West, there is a different approach to FGM than to cosmetic genital surgery, regardless of the similarities of the procedures.

Inventering av röjningsobjekt från helikopter :

In time with HolmenSkog district Egenskog Norrköping´s decreasing mountain of cleaning, the office started to look around for new alternative cleaning strategies to lower the costs connected with cleaning. One option was to make the inventory strategy more effective and after a phonecall with the head of the district, Jonnie Friberg, the planning started to try inventory in pictures taken from a helicopter. The pictures was at last taken from a digtal camera and the vegetationheight was mesured with a laser. The gear was supplied from Kallax Flyg AB, Luleå. In the trial 15 stands was selected depended on age and different mixtures between pine (Pinus sylvestris), spruce (Picea abies) and birch (Betula pubescense and Betula pendula).

Förstudie för automatisering av gjutgodsrensning

This thesis work has been performed at the Division of Assembly Technology at Linköping University for a period of ten weeks. The work is part of the project ProFlexA, which is a research project in collaboration between Linköping University, Lund University, and industrial partners such as Combi Wear Parts and Smålands Stålgjuteri AB.The casting process creates random incurred burrs and defects, which must be removed during a cleaning process to make sure that the cast can be sold. Automation has long been sought for the cleaning of castings due to, among other things, poor working conditions for staff, but this has proved difficult to implement with today's technology. Automation has for some time been available for more capital strong companies with large annual volumes, but for smaller companies with small-and medium-sized volumes, automation has not been an option.The goal of ProFlexA is to develop an automated cleaning cell aimed at small-and medium-sized volumes.The goal of the thesis is to do a pre study at ProFlexA?s partners on cleaning of castings, and develop concepts for automated cleaning of castings.By recording the process and cycle times, the cleaning of castings has been documented as it works today, and on this basis, information and statistics has been compiled.

Förbättrar en kvalitetssäkring skördarens dimensionsmätning?

In this study it was investigated if the adoption of a new routine for quality control could improve the precision of the dimension measurement obtained by harvesters. Data was collected from three different harvesters. First, a reference data set was collected before the new procedures had been incorporated, and then when the new methodology was implemented another data set was collected by the harvester operators, allowing the two data set to be compered. The results indicated that following the implementation of the new procedures, the reliability and the precision of the measurements has increased. All harvesters included in the study had improved regarding most of the controlled factors such as standard deviation, systematic difference and hit rate within ± 2 cm for length and ± 4 mm for diameter..

En j?mf?rande studie mellan tv? v?treng?ringsmetoder p? papper

Amongst the published literature researching wet cleaning of paper there is a limited amount of studies conducted researching the method simmering water treatment. There are even less studies conducted on how simmering water affects the paper being treated when used as a cleaning method. Despite the limited research, there are literary reviews describing the method and suggesting it as an alternative for conservation of paper with iron-gall ink. The following study will therefore be examining, the somewhat unusual method, simmering water treatment, and comparing it to one of the more common wet cleaning methods: immersion washing. This is done to compare how the different temperatures of the water affect the paper. The types of paper used in this study consists of three dyed and four undyed papers. All of the papers are new, apart from one sample originating from 1847.
