ABSTRACTThe fauna of the Lower Cambrian is far from fully understood, as is the environment of that epoch. Some of the most crucial moments in the history of evolution takes place during this epoch; the Cambrian explosion and the appearance of ecosystems as we know them. That makes it an important period to investigate. Doing so, the Lower Cambrian offers a lot of problems, one of which is that body fossils are seldom preserved. That has often left us with trace fossils to create an image of the Lower Cambrian life, but also some bedrock features such as ripple marks.The main purpose of this work has been to investigate the possibilities of relating the wave lengths and forms of recent wave-generated ripples to fossil ones, and also to evaluate the methods for that kind of comparison.

A today common soil reinforcement method is the installation of lime-cement columns. Lime-cement columns have been used since the 1970?s and have been a useful method for stabilizing soil at great depths. It is mostly used for stabilizing road and railway embankments because the method is economically viable and the columns are easy to install. The total costs for the installation of the lime-cement columns is dependent on the numbers of installed columns, what percentage of lime and cement that has been used and the pattern in which the columns has been installed.

AbstractPurpose/Aim: The aim of this essay is to paint a picture of science news reporting in the Swedish Public Service science programme, vetenskaps-radion. Key issues to be adressed are: What areas in science are prioritised? How much of the total broadcast time are devoted to each area? Are there any differences in reporting between weeks? How well does the swedish science radio match common interets? Are the news in the form of short ?soundbites? or are they more lengthy in-depth?Material/Method: Quantitative analysis of radio programmes. The variables used are based on the different major areas in natural sciences.Main results: This study shows that most broadcast time is devoted to news regarding biology and medicine and that the news rather are in the form of short snippets of news than more lengty in-depth stories. This is put in light of how journalistes tend to present news and that the subjects involved has to relate to peoples everyday lives.

The anatomy and physiology of reptiles and mammals are in many ways different, and will therefore possibly complicate anesthetic administration. Lizards are ectothermic and one should keep in mind that a decrease in the lizard?s environmental temperature may result in reductions in anesthetic metabolism. Respiratory depression is a profound problem because lizards lack a diaphragm, making inhalation and expiration completely active processes. This, in combination with cardiac shunting and breath holding makes the effects of anesthesia unpredictable.

Abstract The benthic macroinvertebrate fauna of 22 natural springs on Öland was sampled, by using a time-standarized kick/sweep sampling technique, in the end of September and early October. The aim was to determine the number of species and their abundances in the macroinvertebrate communities in springs and how/why these may change between different springs. Likewise there was a purpose to investigate possible differences between springs considering the proportions of the number of species and the abundances of the five functional feeding groups; shredders, collectors, filter-feeders, scrapers and predators. There was also an aim to investigate if the distances betweeen springs had any influence on similarity between the communities of benthic macroinvertebrates of the springs. Analysis from the springs collected material showed several interesting patterns in the number of species and their abundances when compared between springs devided into groups depending on their environmental factors such as depth and pH.

Background: The development of the Swedish demography is one of the most important social and economic changes ever in Swedish history. Society as well as business is facing an age chock since almost every other company owner is over 50 years old. The complexity of managing a successful succession is pointed out as a major threat to the Swedish economy by the organization Svenskt Näringsliv.Purpose: The purpose with this master thesis is to identify and analyze critical success factors for a successful succession from a going concern perspective.Research method: By using the strong aspects from the quantitative as well as the qualitative method, high level of order and systematic could be reached, without loosing too much details and depth in this particular research. The empirical data was gathered by a digital survey sent to 3000 companies. The quantitative research was complemented by 6 qualitative interviews to increase depth and reliability.Results: The study shows that there is a great incongruence between the expected problems associated to the succession and the actual outcome.

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease. The disease is the fourth leading cause of death and more than 5 percent of the adult population worldwide is affected.The aim of this study was to investigate the association between periodontitis and COPD.Search for material for the literature review was done in the medical database PubMed where the keywords were: "Chronic obstructive pulmonary disease" and "Periodontal health or periodontal disease". The result is based on twelve studies that were extracted and analyzed. The studies have investigated pocket depth, attachment loss, plaque index, bleeding on probing and bone loss. Ten studies compared a COPD group with a healthy control group, one study compared two COPD groups and one study examined a COPD group and a group with other lung diseases.Most studies found that people with COPD had a higher incidence of pocket depth, attachment loss, plaque index, bleeding on probing and bone loss.

The aim of this study was to describe preferences of geographic direction of ten, oak-living epiphytic lichen species and how they responded to sun exposure, nearby bushes and trees, bark fissure depth and circumference. The frequency of every species was recorded in arcs of ten degrees around the tree at a height of 130 to 180 cm above the ground. An estimation of the amount of every species in every arc was also recorded. To analyse how the distribution of the lichen species responded to the different factors their concentration for every tree was plotted against the four factors. The distribution of Cliostomum corrugatum had a positive response to high sun exposure and a negative response to a thick layer of bushes and trees.

In this paper we have theoretically built a house designed for people with impaired mobility. Theessay begins with an introduction in which the purpose of the work, the methodology and thedepth-research part is presented. Then the layout that explains how we intend to adapt the housefor the demands detailed in the depth-research part is presented. In the same chapter variousstructural components, such as different floors and walls, are specified.In the selection of materials we have taken into account the criteria of our specialization andadaptation to the aesthetic aspects, where we evaluate materials based upon our wishes regardingtechnique and form. There are also other aspects that are important in the selection of materials,including that these are adapted to technical traits of the construction elements and installations.In a later chapter the technical installations such as ventilation systems, heating systems,electricity and sanitation are presented, where both technical and financial aspects are describedin detail.

The purpose with this final paper was to examine how the collaboration between parents and teachers can manifest itself. With collaboration, we mean the dialogue that has to exist between parents and teachers in regards to e.g. how well informed the parents are about the regulated principles on which the education plan is built on, and in which way they can take part in and influence the system. This is to empathize on the fact that a good collaboration between parents and teachers help create a good foundation for the pupil?s ability to learn.The method that we have used are questionnaires given to parents and teachers along with studies of literature both as means of furthering our studies as well as a basis for the design of the questionnaires.

Our purpose with this paper has been to analyse and discuss how motivation of the personnel affects the service quality in service companies. This has been done through two studies; a literature study with existing theories and an empirical study on the divisions of Lyckohjul and Shopping at Liseberg. In the introduction of this paper we put the question of research; why is there a need for work of motivation in service companies. When collecting information we used literature briefing, a questionnaire study and depth interviews. The literature briefing focused on the well-tried and most dominating theories on the subject motivation.

In order for a business management to be able to make informed decisions for their companies need enterprise management system regularly checked by internal audits. The aim of purpose with this work was to develop a working manual for integrated internal audits. This was done through a litterature study and interviews with auditors. An in-depth interview was conducted with an experienced auditor to get more understanding and depth of the internal audits process, and how the manual could be designed. Discussions were held with the person responsible for environment, health and safety at Swedspan Hultsfred to adjust the manual to the company?s internal management system.
