Nyateism vs teism-debatten : En analys av Dinesh D'Souza's argumentation
During the last few years the western world has seen an increasing interest in the topic of atheism, with bestselling books by writers like Richard Dawkins, Sam Harris and Christopher Hitchens. The critic of religions that these writers have brought to the table have not gone unmet, with writers like Dinesh D'Souza rushing to the defence of Chrisianity.Taking on the arguments of New York Times bestselling author Dinesh D'Souza in the current debate on the existece of God and the usefullness of religion, I here examine the claim by D'Souza that atheism, in fact, is responsible for the worst mass murders of history. In taking D'Souza's arguments and analyzing them on its own philosophical merits, with methods like the process of elimination and information evaluation (i.e source criticism), I will here show just exactly how persuasive these arguments prove to be. In the following pages we will not only discuss the role of atheism in 20th centuary totalitarianism, but also answer questions like ?Was Hitler an atheist or a theist??, ?Is atheism responsible for the worst crimes of history?? and ?Are people who believe in God in fact more moral the those who do not??.
A porcine type 1 Diabetes Mellitus model, for non-invasive in vivo imaging of the glucagon-like peptide-1 receptor in the pancreas, using [68Ga]Ga-DO3A-VS-Cys40-conjugated synthetic exendin-4 in PET-CT
Diabetes mellitus is a rising epidemic throughout the world and there is currently great interest in quantifying the beta-cell mass (BCM) in vivo non-invasively. In the present experiment, the feasibility of in vivo imaging of the glucagon-like peptide-1 receptor (GLP-1R) in beta-cells was examined, using the positron emission tomography (PET) tracer [68Ga]Ga-DO3A-VS-Cys40-exendin-4 as a marker, in native pancreatic beta-cells of a porcine diabetic animal model and healthy controls.
Eight Swedish high-health domestic pigs were randomly assigned to be either controls or made diabetic using streptozotocin (STZ). The experiment proceeded during eight weeks, starting with an acclimatisation period. Once the pigs had been socialised they underwent surgery for the insertion of a jugular vein catheter, allowing induction of diabetes with STZ, intravenous (i.v.) injections and stress-free blood sampling. Development of diabetes was confirmed by clinical examinations, blood glucose values and insulin-staining of pancreatic sections post mortem.
The diabetic pigs were insulin treated and responded well.
Synen på internkommunikation i större organisationer : Att förmedla information eller att skapa ett budskap
According to science internal communication is a complicated, yet very important, issue of organizations today. An organization with a successful internal communication shows better results both economically and in terms of coworker satisfaction. The two main theories on communication are sensemaking and transmission. After a century with a transmissionary point of view, researchers stress the importance of sensemaking internal communication.Main question of this thesis is ?Which of the two main theories is the most useful when anchoring important messages in large organizations??According to the results of this study, conducted by interviews, neither one is more useful than the other.
Inkludering och språkutveckling i klassrummet för andraspråkselever ? utifrån ett lärarperspektiv
The purpose of this study is to investigate what five primary teachers in five different schools with many second language students have for an idea about inclusion, language development, practices and environment of the multilingual classrooms. In my study I discusses teachers 'views on the multilingual classroom, inclusion, development of language in a language developing classroom environment and the importance of language skills has for multilingual pupils' language development and learning of the Swedish language. The method used was unstructured interviews using a digital recording device. The results showed that for these five teachers, meeting second language learners was in there everyday teaching, while it is a challenge to motivate and support them on their level. The teachers work diligently to find a balance and a working classroom environment for the multilingual classroom where all students, regardless of conditions, background, experience, knowledge and language could be offered an equal opportunity to education. .
Åsktransienter och överspänningar : En spänningsfylld simulering av elkraftsystemet vid Forsmark 3
A power system will inevitably be subjected to transient overvoltages, most often produced by switching operations and lightning strikes. These transient overvoltages may harm sensitive equipment without sufficient protection, but it is not an easy task to predict what transients may occur or how they affect the system. A fault occurred in a low voltage system at Forsmark 2012 and overvoltages from lightning were concluded as the probable cause. The three aims with this thesis are to develop and test a model of the power system at Forsmark 3, analyse the transient behaviour of the system when subjected to lightning surges and identify critical parameters, and lastly to provide a tool for investigating the protection of the system. The modelling and simulations were performed in the freely available simulation program LT Spice.
Elevers självkänsla : Hur stärker vi den i skolan?
The overall aim with this study is to elucidate outdoor education as an education method and on the basis of that illustration to examine active educators vision on it as a way to motivate students' learning. This study is based on a literature component and a qualitative study through interviews five teachers.The results of the interviews show how to interpret the motivation and how to work with students' motivation. As well as outdoor education as part of the activity. The interviews show the importance of outdoor education can be to increase students'motivation for learning. They also show the importance of outdoor education is for student learning and test scores have shown the effectiveness of student learning through outdoor education.
Rädda, varna, larma, släck! - En studie om förhållningssätt till varumärke inom den kommunala räddningstjänsten
This study examines how the local rescue services relate to the brand of the rescue service and the concept of brand management. To understand the attitudes against the brand and brand management, empirical data, theoretical modelling of brand and current laws have been discussed together in a try to get an overview how the rescue services practically works with the brand. The study results are based on a questionnaire survey and qualitative semi-structured interviews. The survey was sent to employees working with the communication of the rescue service. The interviews were held with two employees working with the communication of the rescue service and two fire chiefs.
Undersökning av sambandet mellan strålningstemperatur och NDVI i Sahel
Several studies have analysed the relationship between Normalised DifferenceVegetation Index (NDVI) and radiative surface temperature. A main goal for moststudies have been to find the best method for carrying out land cover classificationsand to study land cover changes, based on a combination between the twoparameters. Since atmospheric components have a significant influence on bothparameters, most applications were based on multi-temporal data. The quality of theindividual values in such a combination is improved, but the biophysical justificationis uncertain. This study presents a different method, based on only the combination ofvalues that have been registered the same day and about the same time of the day.125 daily images of NDVI and 250 images of radiometric temperature were used inorder to analyse the relationship between (1) NDVI and radiative temperature and (2)NDVI and relative temperature difference between early morning and mid-day.Results between NDVI and radiative temperature show a significant negativecorrelation on areas where a distinct growing season develops, and a strong positivcorrelation where vegetation is abscent throghout the season.
Anglosaxarna och Brittanien : Kulturell Identitet hos ett Migrerande Folk
Many questions are still left unanswered regarding the period c. 450-700 AD, when hordes of Anglo-Saxon migrants landed on the British Isles and by doing so made the starting point in the foundation of England. Who were these Germanic tribes? The theories of how the migration proceeded are today many. The two major theories today concerns whether it was a question of a mass migration or a gradual migration proceeded by smaller groups of military elite.
Behovet av en genomtänkt kommunikationsstruktur- en studie av ett projektorienterat företag
Every organization goes through the same lifecycle. Through every step in the transformation to a better organization the communication structure changes. In this report there are examples of the communicational disadvantages that is connected to the communicational structure.By choosing to not have a formal communicational design, the manager takes a risk in spreading the information, the interaction, the control and the balance in creativity and constraint.This case organizations problem is that some parts of the organization has made more progress in the communicational structure than other parts. In this case the Collectivity structure has met the Formalized structure.Tha structural differences has came to affect the way of sharing information and it has become a situation where the information about the products is not stored in a safe way from a quality point of view. There is a gap between the two different ways of communicate.In this report I have created a model to identify problems in the communication structure.
System 348 - Rekombinator : Analys av reglerproblematik vid O2
In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.
Den positiva hälsovågen : En kvantitativ studie om hälsofrämjande arbete
The construction of buildings and paved surfaces changes the natural water balance.Precipitation generates surface runoff and storm water instead of infiltrating into the soil.Storm water has come to be considered as a major source of pollution in lakes and streams inthe vicinity of urban areas. Reduction of pollutants in storm water is a key action in order toprotect sensitive recipients and maintain high water quality. Storm water is traditionallytransported by storm sewers to the nearest recipient. In recent years the approach to stormwater management has changed; storm water should primarily be disposed of on site, throughlocal disposal of storm water, LOD. LOD is created by a combination of the function ofseveral smaller local facilities and the general sewer system.
Modellstudie av föroreningsretention i Bäckaslövs våtmark : Tillämpning av modellverktygen MIKE SHE WET och MIKE 21
During the nineties, ecological handling of urban storm water became very popular in Sweden. Together with Chalmers University of Technology and two Swedish communities, DHI Water and Environment has been doing research of storm water ponds and constructed wetlands. This thesis work is a part of that research project. The work has been applied at the Bäckaslöv storm water treatment plant in Växjö, Sweden. The plant consists of one storm water pond and a downstream constructed wetland.

This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.
Lånad Identitet - En kvalitativ studie om konsumenters inställning till tillgångsbaserad klädkonsumtion
Previous studies have shown that there exists a gap between purchase intention and behavior in consumption situations. This gap is especially prevalent for sustainable or green products and even more so in terms of sustainable apparel consumption. Therefore, the adoption of sustainable fashion remains low as fast fashion dominates the industry. A counter-movement for mass consumption - access-based consumption - has reached the apparel industry and in Sweden we see it in the form of clothing libraries. This qualitative thesis uses in-depth interviews to uncover the feelings of seven consumers towards the idea of accessing rather than owning their clothing as a more sustainable consumption form, factoring in the strong identity connection that we have to our clothes and how this affects their perceptions.
