Numerisk modell för global transport av spÄrÀmnen i atmosfÀren

The aim of this project was to develop a numerical model simulating the global transport of air pollution. The model currently used by SMHI, the Swedish Meteorological and Hydrological Institute, was intended to perform such simulations at regional scales. However, the usage of a grid based on longitudes and latitudes makes this model work poorly in global simulations. The problem with this grid is that the nodes are concentrated near the North and South Poles. Due to this characteristic, the Courant, Friedrich and Lewy-condition for numerical stability puts a sharp bound on the timestep length.

En studie av sedimenttransport, död ved och kantzoner lÀngs tvÄ vattendrag i Kilsbergen - frÄn skog till slÀtt :

Headwater streams are affected by anthropogenic impacts at multiple scales. One aspect of human impact is sediment transport associated to the abundance of stream structures as large woody debris and the composition of the riparian zone from forest to agricultural landscapes. Riparian buffer zones and stream structures like dead wood are considered as generally important structures for protection against an increasing amount of sediment particles in the water. Hence, in this study these structures were quantified in thirty different stream segments on land and in the water. To measure the transport of sediment Whitlock-Vibert boxes were used in three different types of landscapes; forest, transition and fields. The boxes were left in the stream segments for three months, the taken up and dried and weighed. The results showed that the transition-land in FrösvidalsÄn had the highest sediment transport. The second highest transport of sediment was in BlackstaÄn at the fields.

DjurvÀnlig hantering av lantbrukets djur i samband med transport

Handling, loading, transport time and unloading in connection to transport of farm animals affect animal welfare. Induced effects include both psychological and physiological stress responses in animals. The physiological parameters may be measured through blood analysis while behavioural changes often manifest themselves through increased vocalisation, escape attempts and apathy. Physiological parameters are additional parameters of importance when measuring animal stress responses. The handlers behavior during transport has been shown to have major impact on animal welfare and the quality of meat. Animal friendly handling and driving of animals create a more manageable work environment for the handlers. To further increase animal welfare in connection to transport, stables should be built with well adapted drift passage and ramps on the transport vehicle.

?H?LLBAR MIGRATION?? En kritisk diskursanalys av Europeiska unionens reglering av asylansvar

This bachelor?s thesis aims to examine how the ?New Pact on Migration and Asylum? construct the discourse on ?sustainable migration? and ?efficiency? in the European Union. The new jurisprudence concerning migration and asylum in the European Union seeks to establish a more ?fair, efficient and sustainable migration and asylum system?. To analyze the discourses, a critical discourse analysis is applied to the former asylum regulation, Dublin regulation III, a revised and withdrawn proposal, Dublin regulation IV, and future legislation.

TvÄ nya trailerkoncept för transport av rundvirke hos Stora Enso : en analys av prestation och flexibilitet

The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods. In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.

Effekter av "Billigaste vÀg" för Stora Enso Skogs transportverksamhet :

Transportation constitutes a large part of the forest industry's raw material costs. Transport also contributes a significant proportion of the carbon dioxide emissions. In order to reduce both the cost and environmental impact different types of decision support are required. These, in turn, require extensive information about the road network and correct information on road path selection and transport distances. In the development of national road data base for forestry (SNVDB) a road selection application has been included.

ÄTA-arbeten pĂ„ Trafikverket

?ÄTA-work? (Changes, Supplementary and Retiring works) is more or less common in all construction projects whether it is about houses, roads or railways, in the planning stage, or in the construction stage. For the Swedish Transport Administration, which is the largest purchaser of infrastructure in Sweden, ÄTA-work is a hotter topic than ever.Economists and managers want to draw conclusions on the projects share ÄTA-work, while the project manager is concerned about whether it is possible to draw any conclusions at all as each project is unique in itself and has its own merits. There is a big variation in the amount of ÄTA-work in different geographic districts in the Swedish Transport Administration.This study shows that the Swedish Transport Administration does not have a unanimous approach regarding the management of ?ÄTA-work?.

Buntning av grot med lastbilsmonterad utrustning :

During the transportation of logging residues (LR) the materialÂŽs low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.

Comparison of four transport systems for enetric pathogens

ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ÂșC) temperature.

VÀtske- och saltbalans i samband med transport av hÀst

HÀstar har transporterats lÀngre strÀckor i Ärhundraden, först med bÄt och tÄg och dÀrefter pÄ vÀg och med flyg.
