Changes in the climate and the environment are largely consequences of human influences. Resources are given to teach adults about the environment. However, there are problems in focusing on adults because it is difficult to influence people when they already have created a lifestyle. We have instead chosen to focus on teaching children about changes in the climate and the consequences of this.Many of the toys available on the market today encourage children to consume. Luxury cars and dolls with hundreds of accessories are often made of materials that has have a negative effect on the environment.Another problem we often encountered during the year is the declining interest in technology and science.
Vad gör en bra park bra? : och hur gör man den bättre?
This our bachelor thesis of 15 p ECTS. Our subject is What makes a good park? ? And how to make it better. The purpose of our bachelor thesis is to provide an overall direction for instrinsic qualities, resource (areas and materials) maintenance, visitor use, visitor experience and a basic foundation for decision-making for the maintenance and enhancement of the parks in Danderyd municipality.
Optimering av UA-Värde : Förbättring av en containerkonstruktion
Envirotainer builds containers that are specialized in transporting of temperaturesensitive products these containers are customized for airplanes. The containers arethen leased to other companies, most often to pharmaceutical companies.Envirotainer are based in Lagga, Knivsta. It is also here where the production of thecontainers is held. The container RAP T2 was designed in the early 80ies. The RAPT2 contains a fleet of about 1220 containers spread all over the world.
Konceptarbete om skidbalk i kompositutförande till BVS10
This thesis has been performed at BAE Systems Hägglunds, which is located in Örnsköldsvik. Hägglunds has a wide background of engineering, where they have manufactured all from airplanes to lifting cranes. Currently they only produce track vehicles at Hägglunds, where they manufacture the CV90 and BVS10 models. This thesis concerns the BVS10 which is an all-terrain-vehicle. The main purpose with the BVS10 is to enable transportation of material and personnel thru tough terrain.
Lyftanordning för kraftuttag
This thesis has been developed inassociation with Strängbetong AB, Sweden.A few years backCementa AB introduced a new type of cement on the Swedish market: Byggcement,which is a Portland Limestone Cement. This type of cement is better for theenvironment and cheaper than Rapid Hardening Cement which is used today at SträngbetongAB.Strängbetong AB isvery interested in a change of cement in the factory and wants to know what ittakes to make a transition from Rapid Hardening Cement to Byggcement.This final projectaims at investigating how the workability and strength development are affectedby a transition from the existing cement to Byggcement and how we can change theproperties of the concrete by adding different types of superplasticizers. Laboratory and factoryexperiments were made, to investigate the transition..
Stenmjöl eller naturgrus i betong : En jämförande studie
The objective of this thesis is to examine the difference in workability in fresh concrete, when crushed fine aggregate replaces natural gravel. The shape of the fine aggregate, packing and flow of six crushed material and three natural materials will be determined by easy studies, the results will be compared with a slump cone test..
Att existera i ögonblicket -Töj, en textil sittmöbel
This project started with an exploration of geometric shapes and textile materials. It resulted in a chair made out of textile bands with different elasticity. The surface for sitting is flat when the chair is not used, and changes in the moment you sit down and gets a new shape. A piece of furniture that adapts to each individual. The chair emphasizes the important relationship between human and product as the person using it becomes a part of the chair for a moment..
Energianalys av etanolproduktion : en fallstudie av Lantmännen Agroetanols produktionssystem i Norrköping
In this thesis an energy analysis of ethanol production at the ethanol plant of
Lantmännen Agroetanol in Norrköping has been performed. The ethanol plant has
been studied in combination with Händelöverket, the combined heat and power
plant which provides the ethanol process with steam. The purpose of this study
was to determine the energy consumption for the whole production chain from
grain to ethanol. The analysis has included the energy consumption for cultivation
of grain, production of chemicals, the production chain for wood chips, the steam
production and the ethanol plant. The grain and wood chips are both considered
raw materials there for the energy content in these are not included as energy input
in the system.

El Niño Southern Oscillation och dess atmosfäriska fjärrpåverkan.
This paper is a literature study aiming to describe scientists newest theories andknowledge concerning the El Niño and Southern Oscillation. Firstly I have described the?normal? conditions with rising and sinking air in Hadley- and Walker-cells in theequatorial Pacific and from there moved on to explaining the reversed circulation patternsand higher sea surface temperatures (SST) leading to rising air and anomalousprecipitation in eastern Pacific constituting the El Niño phenomenon. My outermostinterest regarding El Niño has been the associated teleconnections, especially in nontropicalareas. I have described the El Niño effect on the Indian summer monsoon, ontropical cyclones and on storms and precipitation on higher latitudes.
Översättning och anpassning av Kortfattad Afasiprövning till arabiska : Jämförelse med arabiska Bilingual Aphasia Test och självskattad språkförmåga
With the growing amount of citizens with another mother tongue than Swedish, the need for assessment instruments in other languages than Swedish within the Swedish health care increases. To enable this, the knowledge of multilingualism and adequate assessments are required. The aim is to develop a modern Arabic version of a screening material that is comparable to what is used in the Swedish clinic in the assessment of people diagnosed with aphasia. In the present study, Short Aphasia Examination (Kortfattad Afasiprövning), which is one of the few screening material is available in Swedish and among the ten most frequently used assessment materials (Blom Johansson, Carlsson & Sonnander, 2011). Translation and adaptation was made to the Standard Arabic (KAPARABISKA) and Arabic dialect of Hadari (KAPHADARI).
Hjälmen under yngre järnåldern : härkomst, förekomst och bruk
Few helmets, dated to the Vendel period are known from Scandinavia and even fewer are known from the Viking age. Paradoxically, picture stones and sagas frequently tell about these objects as if they were very common, something that is contradicted by the archaeological material. The purpose of this thesis is to examine different literary sources and compare these to the archaeological materials and by doing so, gets a clearer picture about the emergence, use, function and of the late Iron Age helmets in Scandinavia..

The purpose of this study was to investigate body awareness among men in military recruit training. BAQ was distributed to fifty recruits for military service in Boden.
Kunskap om och attityder till dopning bland styrketränande unga vuxna : En kvantitativ undersökning i Mellansverige
The main purpose of this study was to determine the self-estimated levels of knowledge about doping for a group of strength training young adults, and also to get an idea of their attitudes regarding the subject. A part of the purpose was also to investigate the potential associations between knowledge and attitude. Method: To collect information a questionnaire was constructed that was inspired by a similar study and in consultation with the tutor. Questions regarding background, doping and training experiences together with self-esteemed attitudes and knowledge about doping were included. Questionnaires were handed out at gym facilities in central Sweden, and were answered by men and women ages 18 to 35 years.
