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.
Utvärdering av laddningskoncept för lastbilsbatterier
When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.
Värmeåtervinning ur spillvatten. En utredning av möjligheterna med spillvattenvärmeväxlare.
This thesis is carried out on behalf of watermixer manufacturer Ostnor AB in Mora.The thesis deals with the area of Article Bound Instructions (ABI) at the company'sassembly department, regarding the layout and management routines involved withthese instructions.In the current situation there are problems with no uniformity in the manner in whichthe ABI is written, then referred to both the civil structure, images and specificityrates in the text.Another problem is that operators do not make use of the ABI that are available inthe current situation, and that there are no clear procedures for who has theresponsibility to write, update and change these ABI.During this work has several people that were identified as key personnel of thethesis held in order to get a handle on how the current situation of the variousobjects of the work looks like, and to examine different desires about the future ofthese should look like from the different subjects perspectives been interviewed.During the work, a number of deficiencies, including that the current program that isused to write the ABI, Lotus Notes, do not possess near the prerequisites for being asimple program to deal with when writing the ABI, which is a condition since wishesare about to put the responsibility for the ABI generation to the departmentsoperators, since their main task is to assemble and do not bother with a program in acomputer.The result of this work has generated new layout and structure of the ABI, designedto be used continuously in the assembly for evaluation, routines regardingresponsibility of the ABI for the Department of Production Engineering (PT),procedures for how the ABI should be written regarding amount of detaileddescriptions in the text and use of pictures.In addition, proposals for further work and improvements has been developed basedon experience during the work and presented at the end of the report..

Framtagning av normalt referensintervall för RDW och retikulocyter på hematologiinstrumentet ADVIA 2120
Erythropoiesis is a complex and carefully controlled process which is mainly regulated by erythropoietin. Using flow cytometry cells in a blood sample can be analyzed one by one. ADVIA 2120 using flow cytometry for analysis of red blood cells (RBC) and reticulocytes. Red blood cell distribution width (RDW) is a component of the RBC method. RDW indicates size variation on erythrocytes and is measured as a percentage of the mean cell volume (MCV). By measuring the RDW anemia can be divided into makrocytic, microcytic or normocytic. Reticulocytes refract light more strongly than red blood cells because they contain some cellular debris. The number of reticulocytes in the peripheral blood reflects erythropoiesis in the bone marrow. The purpose of this project was that by approved methods to establish reference ranges for the parameters, RDW and reticulocyte counts.The individuals who participated in the study, n=124, were considered healthy and had varying ethnicity. Reference subjects had not donated blood the last six months and participation in the study was voluntary.The statistic evaluation includes examination of distribution, and reference ranges for both men and women were established using the 2.5:t and 97.5:t percentiles. The calculated reference interval for RDW was between 12.0 ? 14.3% and the calculated reference interval for reticulocytes was between 38.0 ? 112.8 x109 cells/L. The results showed a significant difference between males and females for the parameter reticulocytes was seen. The difference indicates that different reference ranges should be established for men and women (p<0,0001). No significant difference between males and females were seen for RDW (p=0,74) indicating that the same reference ranges can be used for both men and women. .
Evaluation of Capital Structure Arbitrage in the Equity-Credit Markets
Purpose: The purpose of this thesis is to test for the existence of Capital Structure Arbitrage oppertunities in the equity-credit markets. Methodology: The mispricing of Credit Default Swap contracts are calculated and used as input in an Equity-Credit market trading strategy. The returns are then evaluated with a modified Value-at-Risk simulation. Theoretical perspectives: A Merton-based structural model, CreditGrades, is used for credit pricing and a mispricing-convergence trading-strategy between the credit and equity markets is implemented. Empirical foundation: Daily quotes for the Credit Default Swap spread of 37 European firms were collected for a period of two years, as well as equity-prices for the same period and the previous two years, used for model calibration.

"Frukostklubben": en studie av en gruppverksamhet för barn med skilda föräldrar i Vellinge kommun
We chose to study the groups for divorced children in Vellinge municipal because there was no evaluation made of these kinds of groups with the involved methods.Vellinge municipal has had groups for children to divorced parents since 2000. During this period of time the total numbers of children in these groups have expanded. As of now, there are two groups.Our goal with this study was to see which way the CAP, Children Are People, manual has been implemented in the every-day work in the group. Several studies have been made about CAP but not in the context of groups for divorced children. We have also examined results in other municipals that have implemented groups for divorced children into their social services.We have interviewed ten children and four social workers.

The purpose of the study is to create an understanding of how these strategies can help developers and product owners to develop adaptive interfaces based on different goals and objectives.
Funktionsupphandling av solelanläggningar
This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.
