This work examines the students´ thoughts on climate change with a focus on carbondioxid through photosynthesis and the carbon emissions from cars. The study is based on two subject areas, one with a focus on enhanced greenhouse effect, and the other focusing on photosythesis. The survey was conducted by means of qualitative interviews with students in grades four and six. The results describe that student´s understanding for photosynthesis and the carbondioxids function for photosynthesis doesn´t change significantly from grade four to grade six. I have divided the students inte three levels based on their understandingof the various fields, and their use of adequate concepts.

Hur vi uppfattar vår omgivning påverkas av alla våra fem sinnen, där denna uppsats tar sin utgångspunkt i hörseln och det vi hör. Utifrån en litteraturstudie och egna reflektioner har ljuds betydelse och hur det påverkar oss i det dagliga livet undersökts. Syftet har varit att öka förståelsen för vad ljud betyder för vårt välbefinnande och hur vi som landskapsarkitekter kan ha ljudet i åtanke när vi gestaltar utemiljön. Ljud är mer än den fysiska ljudvågen. Det kan ge oss information om vår omgivning, spegla rörelser, underlätta orienterbarheten och vara en del av hur vi uppfattar rumslighet. Vi hör hela tiden, men lyssnar inte alltid medvetet.

In this essay different aspects of the motif of the criminal have been traced in Lotta Lotass?s Min röst ska nu komma från en annan plats i rummet and Vladimir Nabokov?s Lolita. By seeking its representation in the texts, the intention was to show how themes, stylistic patterns and narrative functions interrelate in the construction of the motif. The perpetrator?s position within the narrative structure and its consequences have also been assessed.By discussing the meta-fictive aspects of the novels I stressed the importance of the reader?s function, arguing the reader?s participation in the construction of the motif..

This report describes how wavefiles can be recorded with programs written in the C++ language . The report also describes how the recorded sound is handled before it can be analyzed. The report describes the different parts that make a wave file to a wave file and how Windows handle these files. There is always some silence or noise of unknown length that passes through the system before some interesting sound arrives. That silence or nose must not be recorded and therefore some function must be developed that can detect interesting sound or speech.

The purpose of this thesis is to examine how gender is constructed in presentence reports written by social workers? as mandated by 11§ LUL. Young offenders are often assigned normative masculine or feminine attributes by personnel at treatment centers, girls are considered emotional and in need of support while boys are considered disorderly and in need of structure. Young female delinquents are victimized which affects their culpability; they are less likely to be held responsible for the crimes they committed. Young male delinquents are viewed as aggressive and in control; they are more likely to be held accountable for their criminal actions.

The aim of this study is to elucidate factors that effect growth of Sarcina lutea and Bacillus subtilis, exposed to the growth inhibitor SDS (Sodiumdodecylsulfat). Agar diffusion experiments revealed repeated, concentric zones of inhibition and stimulation upon exposure to Sodiumdodecylsulphate or to Amoxicillin. Temperature, nutrient concentration and inhibitor concentration were controlled. Formation of successively repeated zones of inhibition, stimulation, inhibition and stimulation is discussed: ? The extension of the primary inhibition zone is due to the concentration of applied Sodium dodecyl sulphate.? Immediately outside the primary inhibition zone the bacteria have access to diffusing nutrients that have not been consumed in the primary inhabitation zone.? In zones of dense bacterial growth the bacteria may produce inhibiting substances, affecting growth of bacteria in adjacent zones.? In zones of dense bacterial growth the nutrients will soon become depleted, thus affecting bacteria in adjacent zones..

This paper deals with knives excavated in the Birka Garrison between 1997 and 2004, in a selection of 100 knives out of approximately 400. The aim is to measure and analyze the material to find out if certain elements in design points to a specific craft. Two groups of knifeblades can be seen, one with a convex bevel and one with a flat bevel of the blade. Considering osteological evidence, historical sources, and the main suitabillity of the knives, it is concluded that some of the flat beveled knives may have been used for crafting leather and fur, whereas the convex beveled knives are of an allround type..

A new system of public transportation that can simplify and shorten the trips made throughout the city, anddo that both cheap and environment-friendly. Sounds like good news. This new system, though, require anall new type of infrastructure, differing from what we are used to see in our cities. Podcar, or PRT, as thesystem is called can become a transport revolution, possibly. If that revolution does happen it is crucial that webeforehand have studied the possible effects it can cause on our city environment, from a spatial point of view.This thesis thoroughly describes the function and essence of the PRT system and presents what is availabletoday and in what forms.

Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

Parkinson's disease is a progressive degenerative neurological disorder. In Sweden there are 15 000-20 000 individuals affected by the disease.The aim of this study was to investigate the prevalence of oral diseases in individuals with Parkinson's disease. The material for the literature review was gathered in the medical database PubMed. Keywords used for the data research were ?Parkinson?s disease?, ?oral diseases?, ?dry mouth?, ?gingivitis?, ?caries? and ?periodontitis?.

Aiming to contribute to the discourse on the sustainability of consociational democracy in plural societies, this case study provides an examination of Lebanon?s power sharing model. The study begins with an evaluation of the Taif Agreement. After acknowledging its effect on Lebanon?s consociational system the function and operation of Lijphart?s four consociational elements are analyzed.

Delirium är en vanlig och allvarlig komplikation hos äldre personer som vårdas på sjukhus och är förenad med försämrad prognos och ökad dödlighet. Syftet med denna litteraturöversikt var att undersöka om särskilda vårprogram har förebyggande och lindrande effekter vid akut delirium hos äldre personer som vårdas på sjukhus, om det finns skillnader i effekt av vårdprogram mellan olika typer av personer och om någon del av ett vårdprogram kan vara mera betydelsefull än andra. Metoden utgick från en systematisk arbetsprocess enligt Goodmans sju steg. Nio kvantitativa interventionsstudier och två kvantitativa litteraturöversikter ingick i analysprocessen. Analysen visade att det finns ett starkt vetenskapligt stöd för att särskilda vårdprogram kan förebygga och lindra delirium och ett begränsat vetenskapligt underlag för att det finns skillnader i effekten av vårdprogram mellan personer med demens och andra personer som vårdas på sjukhus.

This essay recognizes and criticizes a commonly held assumption that Corporate Social Responsibility (CSR) functions as a ?savings account of trust? between corporations and consumers. Based on five focus group interviews, the authors discuss how corporations that engage in society can sometimes raise and sometimes destroy the trust of potential consumers. One of our main findings is that CSR seems to raise the expectations among consumers. We then compare this phenomenon with the classical theory of the disconfirmation paradigm.
