Utformning av ett svenskt försvar mot fjärrstridsmedel av typen kryssningsrobotar och ballistiska robotar
I uppsatsen studeras hur ett svenskt försvar mot kryssningsrobotar och ballistiska robotar kan utformas.Uppsatsen konstaterar att en aktör med tillgång till kryssningsrobotar och ballistiska robotar har enfjärrbekämpningsförmåga till en förhållandevis låg kostnad. För att ytterligare förstärka sinfjärrstridspotential kan aktören förse dessa vapensystem med massförstörelseeffekt. Uppsatsen visar att ettframtida försvarskoncept mot det aktuella hotet är en kombination av offensiva och defensiva insatser. Föratt skydda nationen från insatser med massförstörelsevapen burna av en kryssningsrobot krävsvapensystem med långa räckvidder så att bekämpningen kan ske över hav eller obefolkade områden. Enbekämpad stridsdel med massförstörelsevapen kan resultera i ett restnedfall med förödande effekt.
"Guud, vad tråkigt." : Matematik och elevmotivation
Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.
Skrämd till lydnad : barn i en sekteristisk organisations grepp
The aim of the study is to investigate attitudes about rapists and to determine whether it is felt that they need treatment, imprisonment or a combination of the two. The study examines differences in attitudes between two different educational groups. The first group of students is comprised of those studying on programs that lead to careers working with people, whilst the other contains students who will work in business administration. The investigation also includes views on which punishment alternative the informants believed to be the most appropriate. The same differences are also investigated between gender and age.

Tillståndskontroll av vätskeringpumpar
Bakgrunden till detta examensarbete är ett behov av att införa vibrationsmätning i form av ett tillståndsbaserat underhåll vid AB Sandvik Coromants produktionsanläggning i Gimo. Underhållsarbetet på AB Sandvik Coromant i Gimo bedrivdes vid tidpunkten för studien som avhjälpande och förebyggande med olika fasta underhållsintervaller. Att införa tillståndsbaserat underhåll skulle kunna reducera kostnaderna, samt medföra en ökad uppföljning av varje maskin i form av hälsotillstånd. Målsättningen med examensarbetet var att utvärdera vibrationer som mätmetod. Arbetet har innefattat fyra, huvudsakliga moment.
Källor i Lagga, en uppländsk slättbygd : Geografisk och geologisk påverkan påkällvattens egenskaper
For centuries, springs have played a significant role in our society as water supplies, reasons for where to settle down, and in folklore. There are different reasons why and where a spring forms, e.g. in what kind of soil it has its outflow. Geographic and geochemical surroundings have an influence on spring-water quality.For this project some of the springs in the Lagga perish, Knivsta municipality, Sweden, were selected for a closer study. Water samples were collected from springs for analysis.
Geokemisk undersökning vid Rävlidmyrgruvan, Västerbottens län : provtagning, analys och förslag till åtgärder
The mining industry, in terms of ore excavation and metal production, is and has been
important to the Swedish economy. In connection with the ore excavation process, large
amounts of partly sulphidic waste are produced. When the metal sulphides are exposed to air and water they are eventually oxidised, which leads to the formation of acidic water with high concentrations of metal cations and sulphate ions, so called Acid Mine Drainage
(AMD). This water may reach the nearest surroundings and cause negative environmental
effects. By covering the waste with soil or water, the oxidation process can be minimised.
At the Rävlidmyran mine in the county of Västerbotten open pit mining took place between
1951 and 1991.
Kemikalier som en del av arbetsmiljön : En fallstudie om hantering av och risker med kemikalier ombord på en svensk passagerarfärja
Kemikalier hanteras i det dagliga arbetet ombord. Syftet med den här studien var att ta reda på hur kemikalier hanteras ombord på en svensk passagerarfärja. Frågeställningarna koncentrerades på produkt- och metodval, kommunikation och tillämpning av rutiner och instruktioner samt riskmedvetenhet hos besättningen. Studien genomfördes som en enfallsstudie och bestod av dokumentanalyser, observationer och intervjuer med besättningsmedlemmar. Resultatet visar att informanterna på däcks- och maskinavdelningarna hade stora möjligheter att påverka arbetssituationen vad gäller hantering av kemikalier till skillnad från informanten på intendenturavdelningen som enbart hade begränsad möjlighet att påverka.

Inverkan av foders växtöstrogener på fysiologiska processer hos produktions- och sällskapsdjur
Phytoestrogens are secondary metabolites produced by plants. Among the plants that make phytoestrogens are soya, red clover and some types of grass. The name phytoestrogen is a collective term for compounds such as genistein, daidzein, biochanin A and formononetin. These compounds are similar to oestradiol-17? in their chemical structure.
Datorbaserad analys av enzymdesign för Diels-Alder reaktioner
This thesis has been focused around the Diels Alder reaction with the goal to design an enzyme catalyzed reaction pathway. To achieve this goal computer aided enzyme design was utilized. Common traditional methods of computational chemistry (B3LYP, MP2) do not do well when calculating reaction barriers or even reaction energies for the Diels Alder reaction. New calcu- lation methods were developed and tested. This was the focus of the first part of the thesis, by choosing a small system, extensive and heavy calculations could be done with CBS-QB3.

Rening av lakvatten vid deponin Degermyran i Skellefteå kommun : Utvärdering av nuvarande reningseffekt och simulering av mängden bildat lakvatten under 2000-talets klimatförändringar
At Degermyran landfill, situated in the municipal Skellefteå, a leachate treatment system was installed in 2005. One of the aims of this study was to investigate how well the treatment system works by using data from chemical measurements made on the leachate before and after treatment. Further this study had the purpose of investigating how the predicted climate changes of the 21st century will affect the amount of leachate generated at Degermyran by using a modified version of Thornthwaites water balance model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come.
Brandsläckning och textil restvärdesräddning Hur saneras textil efter en pulversläckning?
This bachelor thesis discusses firefighting and the use of portable fireextinguishers in the salvageof historic artefacts focusing on textiles. It also looks into the use of multi-purpose dry chemicalextinguishers in a textile context and the impact the actual dry-agent has on textiles afterfirefighting.Literature studies, interviews and tests on different textiles were carried out to write this thesis.During the tests textiles were exposed to the dry agent and also to dry agent plus water toinvestigate the difference in residue. After vacuumcleaning it was clear that when the textile wasexposed to dry agent and water it was almost impossible to remove the chemical without rinsingin water.By examining the residue left on the textile using SEM it was possible to see if a textile was aswell decontaminated after vacuum-cleaning as it looks to the eye. We know that the dry agentoften consists of ammonium phosphate which acts corrosively on many materials and one canassume it damages textiles as well after longer exposure.Buildings housing cultural collections are vulnerable as we cannot easily replace ruined materialwith new.
