När förmänniskan blev den moderna människan
The subject of this bachelor-level thesis in archaeology in the transition from archaic sapiens to anatomically modern humans, and what might have caused this transition. A part of the study aims to prove or disprove whether an increased consumption of shellfish might have caused this development. Another part of the essay deals with the connection of said evolution and the suggested emergence of cultural and ritual practices in South Africa circa 100 000 BP and an evaluation of the arguments concerning the aquatic ape hypothesis, and their usefulness for the subject.The result of investigation of the theory about the increased consumption of marine resources as a probable cause of the last biological step of creating our species points to the conclusion that it is a probable explanation. There is even some evidence that there could be a connection between consumption of marine resources and the "Out of Africa 2"-theory. It is harder to find a proven connection between the suggested emergence of cultural and ritual practices, even some evidence seems to strengthen the idea.
Miljöutredning : ett fastställande av betydande miljöaspekter samt lagar och krav som rör Skaraterminalen Spedition AB
The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Evaluation of preanalytic methods in order to shorten the processing time before identification of fungal microorganisms by the MALDI-TOF MS
Identification of fungi is based on macroscopic observations of morphology and microscopic characteristics. These conventional methods are time-consuming and requires expert knowledge. For the past years Matrix-assisted laser desorption ionization-time of flight mass spectrometry has been used for routine bacterial identification in clinical laboratories but not yet in the same extension for fungi. In this study three preanalytic preparation methods for fungi were evaluated in order to shorten the processing time in routine laboratory performance.Clinically relevant strains (n=18) of molds and dermatophytes were cultivated on agar plates and prepared according to the different preparation methods for protein extraction. Each strain was analyzed in quadruplicate by the MALDI Biotyper and the database Filamentous Fungi Library 1.0.The results showed that the genus and species identification rates of the least time-consuming direct extraction method were 33% and 11% respectively.
Forensic Carving from Unallocated Space
Computer Forensics investigations have become more and more common while investigating IT-related issues. From experience, hard disks, USB thumb, memory sticks contains information that might be useful. Computer Forensics is regulary conducted by Police, Customs, Tax investigators but also within private companies and organisations. However, there are areas within the storage device that are not part of the organisied structure that a file system gives. The reason for that might be that the information has been erased by intention, a virus destroyed the file system and so on.
Arbetsmiljöekonomisk utvärdering av ergonomiförbättringar : Grundade i antaganden om sjukfrånvaro och förändring i arbetsbelastning efter intervention inom en avdelning i läkemedelsbranschen
The purpose of this study is to incrementally, through a combination of various methods, examine the assumptions about the working economic outcomes that can be made based on planned ergonomic intervention in a department at Pfizer Health AB in Strängnäs. The study contributes to knowledge about how assumptions on OSH financial results can be made, based on planned ergonomic interventions. These assumptions were based on biomechanical calculations made on the basis of ergonomics measurements with inclinometer. The study is important because previous research has shown that poor work environment have a bad impact on the economy of a company in different ways. It can for example be negative impact on the company's productivity and quality of the units produced or the services provided.
Patienters upplevelser av epiduralanestesi i samband med kirurgi - En intervjustudie av epiduralanestesin
ABSTRACTIntroduction: An increasing number of patients in Sweden receive epidural anaesthesia (EDA) in connection to surgery. Caring for patients with acute pain is a responsibility that is strongly established within the profession of the nurse anaesthetist. If the care provided by the nurse anaesthetist for patients who receive epidural anaesthesia is to evolve then further insight and knowledge is required regarding the individual´s experience.Aim: To describe patients' experiences in receiving epidural anaesthesia based on an earlier perioperative start-up of the EDA.Method: Based on a qualitative approach, the aim is to conduct semi-structured interviews with patients who receive EDA in connection to abdominal or gynaecological surgery. Research subjects' statements in the context of the interviews will be transcribed and then analysed using qualitative content analysis. In order to evaluate the chosen method regarding data collection and analysis model an exploratory pilot study was conducted.
Hur hanterar skolor hot och våld? : En fallstudie av ansvarsfördelning och implementering av riktlinjer på skolan
How schools handles threat and violence among pupils could have an effect on the surrounding world, since schools reflect society at large. This study attempts to explore how this is handled within two schools, one secondary school and one upper secondary school. How do the schools work with violence and threats amongst pupils? Who is responsible for what? Is this work based on school guidelines? Why/why not? The theoretical starting-points have been Lundquists implementation-based control-model and an organizational point-of-view using theories about open and closed systems, primarily Meyer and Rowans neo-institutionalism. To gain validity, the study has been carried out by way of triangulation, i.e.

Skola för framtiden : är entreprenöriellt lärande essentiellt för utvecklingen av kreativiteten inom skolvärlden
Creativity and innovation have become two very important concepts in today?s society where the demand for these abilities are sought after. At the same time, the school system of today follows a more traditional outlook on what learning and knowledge means.The extend students ability to understand and elevate their motivation is possible through creative methods of working. In order to create a school system which can withstand the demands of the future by including creative methods in its model, a study was carried out to examine how teachers? thoughts on creativity could mean for its development.This study took place in an elementary school in Sweden where Entreprenöriellt Lärande (EL) has been in use for the last two years.
Uppkomst av materialspill vid nyproduktion av flerbostadshus
Construction waste from the housing industry includes all unnecessary consumption of building materials. The definition of construction waste is construction materials that has not been built in and becomes waste. Constructions waste can be divided into two types of contributions: operational and work site contribution. Some of the common construction materials in housing industry have such low usage level as 75 % and the rest becomes construction waste. Low usage of construction materials creates unnecessary costs and has a major environmental impact.
Läs-och skrivinlärning : en kvalitativ undersökning av fyra pedagogers val av metod i läs- och skrivundervisning
Background: Language skills are of great importance for all work at school and for students' future life and activities. Therefore it is particularly important that preschool and school in every way possible should encourage and support ALL children's linguistic development. Many linguists points out that all learning takes place best in natural and meaningful contexts and around a meaningful content.Theory: The study is based on theories created by the renowned theorist Lev Vygotsky who illustrates what is important to encourage children's reading development. Vygotsky?s theories regarding the zone for the next development were reflected in the study.
