Sewer trenches usually contain material with a higher hydraulic conductivity then the adjacent soil. Thus they can serve as paths of preferential flow in a polluted area. Wastewater from factories can also leak from wastewater pipes and pollute the soil in the sewer trenches.The purpose of this project was to investigate pollutions in sewer trenches and in sewer pipes in the industrial area of Köpmanholmen, 20 km south of Örnsköldsvik in the north of Sweden. To make an estimation concerning the potential of transport of pollutions in sewer trenches, hydrological calculations were performed.Leakage to any greater extent did not seem to be a problem in the area. This is the case both for the concrete and the wooden pipes that have served as factory wastewater pipes.

Intention: The purpose of this thesis is to see if an active investment decision in the Swedish Premium Pension System would result in a higher return than a non-active investment decision. A non-active investment decision is equivalent to leaving the money in AP7 Premium Savings Fund.Method: This thesis is a statistical analysis and has a descriptive character in which the calculations are based on secondary data, thus the thesis has a quantitative character. Furthermore three active portfolios in different risk categories have been chosen. These portfolios are compared with the AP7 Premium Savings Fund?s returns.

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

Nya och ovana situationer är en orsak till psykisk stress hos nötkreatur då de som bytesdjur ser nya saker som tecken på fara. För nötkreatur kan både kontakten med människor och själva vistelsen på transportfordonet vara nya situationer som ger upphov till stress. Genom att vänja nötkreaturen vid kontakt med människor kan man minska den psykiska stressen i samband med hantering och transport. Hur många djur som transporteras per enhet yta är en viktig faktor för hur stressande djuren upplever transporten. Vid för hög djurtäthet är transport mer stressande för djuren, något som visar sig i ett förhöjt plasmakortisolvärde.

The main interest of this study was to investigate whether there is hyperglycemia or hypoglycemia in cows suffering from abomasal displacement and to evaluate the effect of transport on blood glucose. Thirty-six cows with left- or right-sided abomasal displacement were included in the study together with 17 cows with other diseases for comparison. Fifteen cows with abomasal displacement and 7 cows with other diseases were sampled before transport. One third of the cows with abomasal displacement had hyperglycemia when the transport effects were corrected for. Separating this group in left- and right-sided abomasal displacement we found significantly higher blood glucose and insulin levels among cows with right-sided abomasal displacement. An explanation for this difference may be a strong stress response secondary to the right-sided dislocation.

Our everyday life is becoming more active and the activities we perform influence the way we dress. Due to an increase in activities undertaken in an urban environment, demands are changing and the need for active wear that meets the new demands follow suit. The four characters represented in the research can be seen as a reflection of the functional features needed, including base layer, mid layer/insulation and shell.Despite the increase in activities, most of our clothes are still constructed on static dummies or drafted on a table in 2D and the main developments within the active sportswear field is driven by material innovation. By creating garments on a body in movement, my aim is to develop new functions and expression in active sportswear through construction.Construction methods in active sportswear are examined and understood through observations and reconstructions and constitute the foundation of a study of movement for a design recovery.The movement and features required for leading an active urban life sets the direction of the development of new func- tional garments. A series of trial and error sessions and draping fabric on a live model in movement created the prototypes used in functionality tests to establish their feasibility.

Bakgrund: Den intensivvårdskrävande patienten är många gånger i behov av transport utanför intensivvårdsavdelningen för diagnostiserande undersökning eller behandling. Transporten är riskfylld då patienten kräver komplicerad utrustning och avancerad medicinsk behandling. Studier visar att patientsäkerheten ökar om policydokument används vid transportprocessen.Syfte: Studiens syfte var att kartlägga antalet policydokument som reglerar intrahospital transport i Stockholms län och jämföra dem med en guideline.Metod: Urvalet bestod av policydokument från 11 intensivvårdsavdelningar i Stockholms län. Metoden utgjordes av deskriptiv dokumentinnehållsanalys.Resultat: Sex av elva intensivvårdsavdelningar i Stockholms län hade policydokument som reglerar intrahospital transport. Policydokumenten hade fem gemensamma huvudämnen: Riskbedömning, bemanning, förberedelse, övervakning och utrustning vilka överensstämde med dem i guidelinen.

Individual cellulose ?bers were studied to identify the transport and absorbtion phenomena as well as the in?uence of drying. A Chalmers University of Technologydeveloped method within ESEM (Enviromental Scanning Electron Microscope) has been used in this study. The results from the laborations gave the following conclu-sions: The transport of water occurs in ?bers in the ?ber wall surface and the lumen.

The aim of this study is to examine if the leadership style in Faiveley Transport Nordic Ltd has an impact on the psychosocial climate in the workplace. Henceforth, we have checked if the psychosocial climate influences the feeling of satisfaction that exists in the organization and if this in turn influences the degree of extra effort the employee chooses to impose on his or her task. In order to measure the leadership in the organization we have used the Multifactor Leadership Questionnaire (MLQ). The climate, in turn, has been measured through Ekvalls GEFA. All 125 employees in Faiveley Transport Nordic Ltd got the possibility to attend the survey, 58 participated.

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.

This paper is about how transport companies in the future will be able to adapt their activity to an environmentally sustainable development without the effect of negative company economic consequences. Today, the environmental threat is a global problem and knowledge about that effluent of carbon dioxide have a negative impact on the climate is generally known. A transport system that works well is important for Sweden, but the sector has a negative impact on the environment. Regulation and legislation for increased environmental requirements often meets resistance and fear that the work will be hampered by increased costs for environmental work that can lead to an international decrease in competitiveness. The transport companies have outside pressure from the society to do something about the environmental issue, however the companies? customers are not ready to pay a higher price for environmental work.

This report discusses questions concerning wear on forest roads. The purpose of the work is to investigate if the wear on the roads will decrease when the speed limit gets lower for the trucks that transport the wood. A normal forest road, class B, was used in the study. In total 5000 m3f timber was transported on the road. Data about the road was measured with a profilograph car before and after the timber transport.

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.

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 Frösvidalsån had the highest sediment transport. The second highest transport of sediment was in Blackstaån at the fields.
