The container RAP T2 was designed in the early 80ies. The RAPT2 contains a fleet of about 1220 containers spread all over the world.

Utveckling av flygtaktiken för att möta det nya hotet

Vid deltagande i internationella insatser kan Flygvapnet komma att möta nya typer av hot som Flygvapnet tidigare inte stött på, vilket medför att en anpassning eller förändring av flygtaktiken är en förutsättning för att undvika flygplansskador. 2000-talets lättviktflygplan medför en skyddsnivå på flygplanen som är låg och motståndaren kan påverka materialet samt konstruktionen i flygplanen genom beskjutning med finkalibriga projektiler.Syftet med uppsatsen är att analysera hur den nya hotbilden skiljer sig från vad Flygvapnet ställs inför nationellt samt analysera hur finkalibrig eld påverkar kompositmaterial och hur det i sig påverkar flygtaktiken.Inledningsvis utgår jag i uppsatsen från en beskrivande metod av empirin i syfte att läsaren skall få förståelse samt bakgrund inom de belysta ämnena för att förstå det som senare diskuteras i uppsatsen. Därefter övergå uppsatsen till en hotbildsanalys i syfte att senare diskutera och dra slutsatser om hur flygtaktiken bör anpassas för internationella insatser.I slutsatsen har jag kommit fram till att finkalibrig elds påverkan på kompositmaterial är mycket effektiv vilket innebär att projektilen slår igenom och deformerar materialet. Vidare diskuteras alternativ till genomförande av start och landning för att minska exponeringstiden och undvika att motståndaren kan påverka flygplanen..

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.

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..

Programverksamhet: ett uttryck för folkbibliotekets identitet

This thesis is a contribution to the discussion on the public library?s institutional identity in late modernity. The aim is to shed light on the public library?s identity as expressed through its public events. The thesis seeks to answer the following questions: What kind of public events are offered at public libraries? What themes distinguish the content of these events? What characterizes the institutional identity expressed through these events? In addition to the concept of institutional identity, a model of four library spaces, developed by Skot-Hansen, Hvenegaard Rasmussen, and Jochumsen, constitutes the theoretical framework of this thesis.

Karaktärisering av avfallsbränslen

All products will eventually end up as waste, which in a sustainable society has to be handled in an efficient and environment friendly way. This report focuses on waste fractions meant for combustion, often difficult to characterize. However, more homogeneous fractions that are treated biologically are also discussed.The study concerns the region of Borås, Sweden, where the waste plant Sobacken has provided a good starting point. On this site, fuel to the Energy-from-Waste plant of Borås Energi is prepared and the biological waste is treated through anaerobic digestion.One important part of the study has been to collect experience-based knowledge from the technical staff at Sobacken and Borås Energi. This information was compiled into an overview of wanted and unwanted fractions to the preparation plant and the boilers respectively.

Analys av fysiskt och administrativt flöde för provhantering vid Höganäs AB

In this project, we are studying the material flow and the information flow of sample materials and the appurtenant report of deviation for the purpose to be able to suggest better solutions. The sample material, which is to be analysed, is to be continuously taken from the production flow. The purpose is to navigate the process by the results found by the analysis. Because of this, it's very important that both methods of analysis are ensured and that the sample material is representative for the production flow. However, even more importantly, is that activities and transportations, combined with both flows, must perform in a quick and correct way in order to maintain or improve Höganäs AB's competitive strength.According to reports are about 20 products per day not available, for loading, at the time of delivery.

Optimerad hygienisering vid kompostering av avloppsslam

The aim of this study was to in laboratory experiments investigate how addition of urea, ECOX and structural materials can optimize sanitization during composting of sewage sludge. Today we strive for a sustainable society and the importance of closing the nutrient loop increases. It has therefore become even more important to safely reuse plant nutrients from human excreta to agricultural land. Partly because it increases the sustainability of society as the world's supply of many nutrients are finite, partly because it promotes human health, both by reducing disease transmission and by increasing Agricultural production. An untapped resource such as sewage sludge that is rich in nutrients and humus-forming materials could replace parts of the commercial fertilizers used in Sweden today. owever, sewage sludge contains undesirable substances such as heavy metals and drug residues, and pathogenic microorganisms.

Energieffektiva bostäder i Kurdistan - Förslag på bostadshus i den kurdiska delen av Irak

Staden Sulaymaniyah ligger i den kurdiska delen av Irak och har på senare år utvecklats då många valt att flytta från landsbygden till den centrala delen av staden. Nybyggandet sker under tidspress och långsiktigt hållbara lösningar prioriteras inte. Målet är att ta fram ett hus som är anpassat för majoriteten av befolkningen och samtidigt få ett bra och energieffektivt inomhusklimat. En faktainsamling genomfördes för att ge bakgrundsinformation till projektet. Vidare gjordes en planlösning till huset i AutoCAD vilken har använts som grund till utformningen av huset och smarta lösningar.
