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.

This paper discusses whether the main argument for European countries to stay out of the euro, i.e. the loss in stability from not having a national monetary policy that can be used for stabilization purposes, is still valid ten years after the introduction of the single currency. We analyse the stabilization performances of four largely comparable Nordic countries that have all chosen different levels of European economic integration. In retrospect, the so-called ?stabilization policy argument? seems surprisingly weak.

The requirements for wastewater treatment plants (WWTP) are gradually increasing, partly because of higher incoming loads, which in turn require a more efficient treatment process. In parallel with environmental and economic goals there are also desires to lower energy consumption without compromising the wastewater treatment. Furthermore, there is a demand on WWTP´s to alter eutrophication in aquatic systems through better nitrogen and phosphorus removal. An increasing number of WWTP´s have acquired biological nitrogen and phos-phorus removal. A by-product of this type of biological treatment is the formation of nitrous oxide, which is a potent greenhouse gas.

En av de större utmaningarna med ombyggnadsprojekt är de fall när det i byggnaden finns kvarboende eller andra brukare under tiden. En ombyggnad innehåller i regel både bygg- och rivningsarbeten som ofta medför störningar för människor som vistas i eller intill fastigheten. Samtliga störningar är påverkningsbara och kan vid god projektering och produktion minskas.Målet med examensarbetet har varit att ge konkreta förslag på hur ett fastighetsbolag kan arbeta för att öka hyresgästens kvalitetsupplevelse under en ombyggnad som sker i eller intill hyresgästens lokal. Detta har gjorts genom att identifiera vanliga störningar, genom att påvisa hur hyresgästen har påverkats av dessa störningar och genom att undersöka hur tidigare uppkomna störningar har hanterats.I samråd med fastighetsbolaget Vasakronan har tre ombyggnadsprojekt valts. På respektive ombyggnadsprojekt har kontorshyresgäster, intern projektledare och extern projektledare intervjuats.  Även observationer i form av platsbesök och litteraturstudier har genomförts.Studien har resulterat i förbättringsförslag till fastighetsbolaget.

After the deregulation of the Swedish pharmacy market customers can be lost due to stock-outs. Optimization of pharmacy inventory levels has thus become increasingly important. To minimize inventory costs while considering the cost of shortages the latter must be estimated. However, the shortage cost is very difficult to compute. Thus, the aim of this paper is to estimate the pharmacy-specific shortage cost parameter and its relation to other inventory costs.

This paper is about the extent to which simplified penetration calculations ofsmall-caliber projectiles is a useful tool for assessing the physical protectioncapability. The work should be seen as an attempt to create an accessible tool inthe form of a simplified equation that allows for a better and safer use of thenaval vessels. The tool will also be used at different levels so that decisions andinstructions could be clearer.Performed calculations show a very limited capacity of a ship's basic design interms of physical protection against the use of small-caliber projectiles.How do we know that the calculations correct? By verifying the calculations withpractical shooting tests, a substantial condition to answer the question will becreated. To shoot against a material with two different thicknesses estimated toproduce perforation and non-perforation is a good approximation of the equationusability in the context..

Logistics is an important concept in the organizational context in which the planning of flows, services and products are treated. Logistics handles supplier management, supply of materials, production and distribution. The distribution of goods can be managed with different types of transportation depending on price and time aspects. The lowest transport cost for larger amount of goods is by maritime shipping. A common carrier used in transportation of goods is a standardized ISO- container.

Methadone is frequently used as an analgesic drug for dogs although there are very few studies describing the pharmacokinetics of methadone in this species. In man methadone has a long half-life and there are considerable differences in pharmacokinetics between individuals. The dose interval is lengthened when the drug is used fore longer periods of time due to prolonged half-life. Therefore the drug dose must be adjusted individually. The purpose of this study was to study the fundamental pharmacokinetics of methadone in dogs, and to find an optimal drug dosage.

The purpose of this qualitative thesis is to describe and analyse the implementation of an education system in the newly independent state, Timor Leste. One question to be discussed is whether an emergency phase is still going on in the development of a functioning school system, or if Timor Leste already reached a capacity building phase? Via the participant's answers in field observations and interviews, the study analyses the clashes between generations, social classes and different levels in relation to the choice of Portuguese as an official language and the international environment in the country. The thesis concludes that a lot of work remains in creating a fully functioning education system. We enjoyed the writing - and hope you will enjoy the reading!.

This master thesis encompasses an inventory of the older industrial community of Gimo. Investigations of the contamination situation for each industrial area were done. A risk classification according to the Swedish Environmental Protection Agency?s ?Method of Surveying Contaminated Sites?, phase one, followed. The risk classification was done on areas of Iron Work, a rockwool industry and a landfill. Gimo have had iron manufacturing from 1615 until 1945. Gimo have had two blast-furnaces and two smithies periodically.

The purpose of this thesis is to systematically describe and map how authorities define the school library and its function based on the current policy documents for the Swedish upper secondary school. The study is guided by the following questions: ? What dimensions does the school library have according to the explicit definitions, descriptions and requirements? ? What implicit arguments, references and unspoken assumptions about the school library and its role, function and significance can be derived? The study is delimited to the national policy documents, which have been divided into two groups ? structural and teaching focused ? corresponding to the two questions above. Further delimitations have been made to avoid noise and to manage a manual content analysis. Each question required its own analysis tool.

This essay will examine the social organization in the archipelago of Tonga. To accomplish this purpose, archaic societies and structures such as ancient Egypt and Hawaii will be examined to obtain a closer understanding of the building blocks which constitute a chiefdom or kingdom. Since Patrick V. Kirch (2010) recently redefined the Hawaiian archipelago as a kingdom this essay will examine if the same can be done with the chiefdom of Tonga since it have similarities to the Hawaiian social organization.To do this the essay will examine and describe both the geographical organization of the states and the social organization. Social organization in this essay will be defined as an archaic state organization that requires several levels of administration to rule the society..

Background: Since1994, the EU NickelDirective is limiting the release of nickel from objects that are in prolongedcontact with skin. Despite this, nickel is still the most common cause of contactallergy in industrialized countries. This could implicate that other productswith short contact to the skin, which are not restricted by EU´s legislation inREACH (Registration, Evaluation, Authorisation and Restriction of Chemicalsubstances), could be a source of nickel or cobalt exposure. There is no limitfor cobalt release within REACH. To determine if there is cobalt or nickelpresent on the surface of a material and if metal can be released in contactwith the skin, there are quantitative and qualitative methods, such as the DMG(dimethylglyoxime)-test, the cobalt spot-test and a method for releasedetermination according to EN1811.Objectives: Laptops are not included in the REACH legislation.
