Riskbedömning vid Saltvikens kopparverk

AbstractAt Saltvikens copperindustry, which is located in the municipality of Oskarshamn, copper was refined from sulphiteore some hundred years ago. The ore underwent several steps in the process before the final product was received. These steps all had an influence on the environment through discharge of heavy metals. The area where the copper industry was located is today considered to be of specific national interest due to its valuable nature and cultural values, as well as its value for recreational outdoor activities. Therefore, it is important to determine the present level of contamination and if any transport of contaminants have occurred, and to identify the risks that are associated with the site both at present and in a longer time perspective.Thirtynine soil samples and 16 sediment samples have been analyzed.

Mekaniserad ungskogsbehandling för röjning och skörd :

Earlier attempts at mechanising pre-commercial thinning have been met with varying degrees of success. Most attempts have been based on techniques where residual stems are straddled. Early treatment is essential to limit damage on residual trees. One part of the present study is an evaluation of mechanised pre-commercial thinning using the new Vimek 404R. Vimek 404R is a fairly small machine that permits selective removal of stems, making it potentially suitable also for areas overdue for pre-commercial thinning. The study established the level of performance for the machine, as well as the improvement needed to make it an economically viable option.

Skillnad i energiförbrukning vid byte från CAV-system till VAV-system i en kontorsbyggnad

Detta arbete är utfört hos Videum AB i Växjö i syfte att visa på skillnader i energiförbrukning mellan deras ventilationssystem samt hur lång tid det skulle ta för en möjlig investering i ett nytt ventilationssystem att återbetala sig.För att uppnå detta utfördes beräkningar på olika faktor som bidrar till den totala energianvändningen hos ventilationssystemet. I denna undersökning behandlas fläktar, golvaggregat och värmeförluster genom ventilation. Den största påverkande faktorn i den totala energiförbrukningen är värmeförluster genom ventilation.Resultatet av vår undersökning visar att det är billigare att använda i VAV-system än ett CAV-system under rådande förhållanden enligt våra beräkningar. En årlig besparing på 29465 kronor per våning vid byte från CAV-system till VAV-system uppnås. Det är värt att byta ventilationssystem även fast att investeringskostnaden inte sparar in sig under dess livstid.

Hälsorelaterad psykosocial situation bland kvinnor från olika kulturer efter bröstcancer

The most common form of female cancer in Sweden is breast cancer and the primary choice of treatment is surgery. Removing a woman's breasts is not just removing a body part but is also strongly linked to the emotional life. This has psychosocial consequences and the reactions will be different depending on how people perceive health and illness. Factors that matter are both personal experiences and cultural factors such as religion, family, and the own standards and values. It is important that a nurse is aware of cultural factors that may influence the perception of care.

Lactobacillus reuteri som probiotisk terapi mot bakteriell vaginit hos avelsråttor :

Lactobacillus reuteri has been used as probiotics in piglet and chicken feedings as well as in different diary products for humans. In this EEF-work I have shown that L. reuteri can be an alternative for treatment of vaginitis in laboratory rats used for breeding. In a breeding stock with 3000 animals some animals had a vaginal infection with ??haemolytic streptococci group G.

Så funkar avdelning C: en kvalitativ undersökning av användbarheten av SAB-systemets religionsavdelning i dagens svenska samhälle

The purpose of this thesis was to find out whether the main class C (religion) in the Swedish classification system Klassifikationssystem för svenska bibliotek is well adapted to classify materials published in or imported to Sweden, and handled by Swedish libraries today. The questions we put to ourselves were:1. How easy to understand, and how useful is the main class C religion today?2. What, in the main class C, is satisfactory?3. What, in the main class C, is inconsistent, anachronistic or incorrect?4. What, in the main class C, is in need of change or renewal?The method that was used was a number of interviews with librarians and cataloguers. We have interviewed eight librarians from six different libraries, of different types, but all with a relatively large collection of religious materials.Though all of our respondents have expressed a feeling that all the major religions deserve equal treatment in the classification system and a similar division of space, after some pondering on the subject, our respondents have agreed that a larger space for Christianity is warranted considering the composition of the current collections and publication. Our respondents have in some cases expressed that there is a lack of instructions as to how the subdivisions of the main class C (religion) is meant to be used.

En jämförelse mellan linjära och traditionella bedömningssystem hos hästar

In Sweden the breeding organization for the Swedish Warmblood horse uses a traditional scoring system when evaluating horses. The horse is scored subjectively in relation to how good each trait is in relation to the breeding objective. Other countries, for example the Netherlands, instead use a linear scoring system. The linear scoring system evaluates the horse on a scale between two, for the breed, biological extremes which makes the evaluation more objective since the judges personal values does not influence as much. The breeding organization for the Swedish Warmblood is today planning a change towards a linear scoring system.

Textilindustrins avloppsvatten och avloppsslam ur ett miljöperspektiv : Underlag för internationella riktlinjer inom projektet Sweden Textile Water Initiative

The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the  ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.

Vägsaltets effekter på växter i urban- och offentligmiljö : ett växande problem

Through previous studies during my education, I have experienced that chemical deicing road salt is a known problem, mainly in southern Sweden. Road salt causes damage to the environment and also damage to vehicles and structures such as bridges, etc. Road salt causes vehicles and steel constructions to rust, leading to increased costs for repairs of damage to structures. Road salt also causes damage to the plants and the economy to suffer, when plant material and soil needs to be replaced. In order to get closer to a solution, I put up three questions.

Frigörelse av fosfor från färskt, fryst och torkat växtmaterial : ett laboratorieförsök för att öka förståelsen för fosfordynamiken inom växtodlingen

Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The dynamics and paths of losses of phosphorus from arable lands are not fully understood. It is known that phosphorus can be lost directly from plant material to water. In studies where plant material has been subjected to several freeze-thaw cycles, large amounts of phosphorus have been lost. Most studies have been conducted under field conditions, with many factors effecting the measured losses of phosphorus, such as weather and type of soil. This study was performed in a controlled environment without the presence of soil. Instead of soil, small glass beads were mixed with the plant materials in vessels, to make possible homogeneous leaching with water through the mixture of glass beads and plant materials. In this study, clover, ryegrass and dry straw were cut to pieces, approximately 2 cm long.

Egenvård vid hjärtsvikt- en enkätstudie om vilka egenvårdsåtgärder personer med hjärtsvikt säger sig använda i det dagliga livet.

Heart failure is an illness that requires life-long treatment and often affects everyday aspects of a person?s life. Self-care is a significant part of the treatment. Good self-care resources make it possible for people with heart failure to make the lifestyle changes they often need to maintain or improve their level of health. Self-care means having knowledge of and being able to recognize the symptoms and signs of deterioration that can occur with heart failure, so that the person can take appropriate measures ? and it also means knowing when it is time to seek professional help.

TECHNOLOGY MEETS THE EYE : Utveckling av system för att jämföra eye tracking data med visuellt stimuli

The purpose of the project was to make a system that could extract data from a mobile eye tracker and make it comparable with data from visual stimuli. The produced system was programmed in Java and provided all the necessary parts that were required to achieve the purpose. This provides a foundation for further research to determine whether the eye tracker is sufficiently accurate to diagnose Parkinson?s disease..

Vem hittar hylla Hcf.03? En studie av en alternativ hylluppställning på en barnavdelning

The objective of this Bachelor?s thesis is to investigate how the public library in Luleå has set about implementing an alternative classification system for its children's books section and to explore why this was done. We wanted to investigate both how they have adapted the new system to the children's own way of seeking information and the library personnel's experience of using the new shelving system. We have done seven interviews to answer these questions and our choice of literature is intended to put the process of change into a wider context. The answers show that the library was dissatisfied with the former system and have instead expressed a desire to shift the focus of their classification system to their users.

Fertilization in Eucalyptus urophylla plantations in Guangxi, southern China

StoraEnso decided in year 2002 to build a pulp mill in the province of Guangxi, southernChina, and also establish eucalyptus plantations to provide it with raw material. By 2010StoraEnso controls about 90 000 of planned 120 000 ha, out of 75 000 ha is already plantedwith Eucalyptus.By using better genetic material, improve the tending, selecting the sites more careful and byusing a proper fertilization regime StoraEnso hopes to increase the mean annual incrementfrom today?s 25 m3/ha, on bark, to 35 m3/ha. This study is one part in this work to increase themean annual increment in the plantation.This master thesis is the forth in a series, that has followed up a fertilization trial that startedin spring 2006 when the trial was laid out and treatments decided. The aim with the trial is toexamine the production potential of Eucalyptus urophylla in Guangxi, southern China.
