Kol-14 datering : En litteraturstudie över hur kol-14 isotopen används för datering, samt utveckling och tillämpning av djup-åldersmodeller inom naturgeografin.

This literature study concerned the use and function of the radioactive isotope carbon-14, as a dating method of organic material, within the scientific field of physical geography. In this report it is presented the need of atmospheric calibration curves and the development of these as a necessity to translate carbon-14 years to calibrated calendar years. A number of common age-depth models that is used to give an approximation of an accumulation sequence and its related dates over the actual time period in different natural archives is presented and discussed. Different problems that commonly occur when age-depth models are utilized as for instance reservoir effects, contaminations or other age deviations are addressed and analyzed. The software CLAM in presented and discussed and was also used to produce age-depth models.

Produktivitetsstudie Brobyggnad

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

Energieffektivisering av stenstadshusen - genom byggnadstekniska energisparåtgärder

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Kvicksilver i skogsmark

I mer än hälften av Sveriges sjöar innehåller gädda en kvicksilverhalt som övergår Food and Agriculture Organization?s (FAO) rekommendationer. Det kvicksilver som finns lagrat i svensk skogsmark är ett resultat av antropogent nedfall. Studier visar att kvicksilver utlakas vid skogsbruksåtgärder på hela skogsmarken som en följd av förhöjd rörlighet av dissolved organic carbon (DOC). En ökad metylering av kvicksilver sker vid vattenmättade, syrefattiga förhållanden där det finns tillgång till organiskt material.

Aquaculture : animal welfare, the environment, and ethical implications

The aim of this review is to assess the ethical implications of aquaculture, regarding fish welfare and environmental aspects. The aquaculture industry has grown substantially the last decades, both as a result of the over-fishing of wild fish populations, and because of the increasing consumer demand for fish meat. As the industry is growing, a significant amount of research on the subject is being conducted, monitoring the effects of aquaculture on the environment and on animal welfare. The areas of concern when it comes to animal welfare have here been divided into four different stages: breeding period; growth period; capturing and handling; and slaughter. Besides these stages, this report includes a chapter on the current evidence of fish sentience, since this issue is still being debated among biologists.

Utlandsetableringar & aktieägares förmögenhetsvärde : En eventstudie om utlandsetableringars påverkan på aktiemarknaden

The aim of this study is to examine the market reaction when information about a company?s foreign direct investment is announced and how that affects the shareholder?s value. Also of interest is whether the market reacts differently depending on which country the investment is established in and which mode of entry is used. This will be achieved by using an event study approach. The selection that was used consisted of 206 companies registered on the Nasdaq OMX Nordic homepage, which had during a time period stretching from 1999 to 2009 established a foreign direct investment in the regions BRIC, Europe or the USA using the mode of organic growth, joint venture or acquisition.

Samband mellan digivning, avvänjning och mjölkens sammansättning med fokus på mjölkfett

Sammansättningen och kvalitén på mjölken som produceras är betalningsgrundande och därmed är det viktigt ur en ekonomisk synvinkel att producera mjölk som håller en hög standard. Syftet med denna litteraturstudie var att undersöka om samband finns mellan typ av digivning respektive avvänjning och mjölkens sammansättning. Fokus ligger på mjölkfettet samt fettsyrorna. De produktionssystem som tas upp är begränsad digivning och artificiell uppfödning. Begränsad digivning innebär att avkomman får gå med moderdjuret vissa timmar av dygnet fram till en senare avvänjning jämfört med artificiell uppfödning där avkomman skiljs från moderdjuret strax efter förlossningen.

Olikhet, gemenskap, kommunikation : En studie om hur lärare i skolår 1-6 främjar tolerans hos elever.

For most pupils homework is a natural part of school and their education and there are several providers of homework assistance: the pupil's parents, sibblings, friends, Internet forums, hired private tutoring, non-profit organisations and at times even the pupil's school. This study has investigated the use of the school-based homework assistance programme at the Upper Secondary School of Psychology in Stockholm and why the programme is not more frequently used by its pupils. The school offers homework assistance two hours each Thursday afternoon, with at least two teachers being present to tender for the school's 127 pupils. The cost of the programme has been estimated to approximately 12 500 Swedish kronor per week. Through the main use of a questionnaire given to both the school's students and teachers, as well as an interview with the school's headmaster, this study will show that despite receiving the opportunity few pupils take part of the programme on a regular basis.

En studie av rörelsen mot en processorienterad sjukvårdsorganisation - eller hur man får upp strutsar ur sanden

Health care costs in relation to GDP are escalating all over Europe and the Swedish health care industry is not an exception. Between 30 and 50 percent of resources used in health care are considered waste, in the sense that they don't contribute to increased health. This illustrates the big need for hospitals to become more efficient which is why many hospitals today are trying to move towards a process-oriented organization. This paper therefore aims to identify the elements necessary for this type of organizational change, the barriers encountered when moving from a functional to process oriented hospital as well as how to overcome them. The case study was conducted at Karolinska Universitetssjukhuset and shows the importance of not just transmitting a sense of urgency but also communicating that the upcoming change is long term.
