När Arktis isar smälter tinar världen upp? : En kvalitativ analys av det vidgade säkerhetsbegreppet i den svenska strategin för den arktiska regionen
This study is called When the ice of the Arctic melts is the world defrosting? and written by Rebecca Fröling.The purpose of the study is to investigate how the concept ?security? is used in the Swedish arctic strategy and why the concept is described in that way. The debate of the concept ?security? has been going on for years, but the debate is still present today. What we put in to the concept is operative for how we regard and discuss security and security politics.To analyze the strategy I used two theories, one with a traditional approach and one with a critical approach to security: Realism and Copenhagen School.The method that has been applied to the study is qualitative content analysis, to be able to analyze the text on the depth.
MIljöifiering "Hur vi slutade att oroa oss för framtiden och gjorde något för att förändra den! "
Denna uppsats syftar till att ta fram ett teoretiskt underlag för hur miljöprojektet CLICC (Climate Living In Cities Concept) i Malmö skulle kunna utvecklas med hjälp av teorier kring de relativt nya begreppen Spelifiering och Captology. Målet är att förbättra den miljökommunikativa processen där de boende i bostadsförening Hilda ska motiveras att minska sina koldioxidutsläpp med 50 procent. Metoden för denna studie utgörs av en kombinerad litteratur- och en fallstudie.
Forskningen kring Spelifiering, Captology och miljökommunikation utgör grunden för denna studie. Detta har sedan kompletterats med en intervju där Miljöförvaltningens projektansvarige för CLICC har gett sin bild av projektet och de hinder som existerar.
Uppsatsen utmynnar i ett antal teoretiskt grundade förslag som behandlar möjligheten att, med hjälp av Spelifiering och Captology, överbrygga miljökommunikativa hinder och uppmuntra de boende till att både delta i projektet och förändra sin livsstil i en mer miljöanpassad riktning..
Erosionsskydd i strandzoner :
Erosion in coastal areas is a common problem all around the world. The range of the problem depends on several factors, i.e. type of bed-rock and soil, wind and wave climate. Another factor is whether the area is of high interest, i.e. if the area is important for tourism and recreation, if there are houses and other buildings close to the shoreline or if it is a site of special scientific interest.
Torkning och pelletering av organiskt hushållsavfall - en konstruktionslösning
The research in this paper aims to producing a home version machine thatcan dry and make biological waste into compact pellets. This product ismade primarily for those who want to improve the environment and reducethe energy consuming process of separating the biological leftovers fromother waste in the large processing plants and save money due to reducedpickups of waste. Since there is no commercially available product thatdoes what we want to achieve we had to start from the beginning with boththe design and the mechanical aspects. The result is a machine, that fits inour homes, and in an easy and inexpensive way reduces the amount ofbiological waste that needs to be collected by the public wastetransportation system. This is done without reducing any of the energy inthe waste and it can still be used to compost or by large-scale plants that usethe waste to make electricity.
STR?VAN EFTER ETT RENARE HAV OCH EN B?TTRE HAVSMILJ?
This literature study compiles available data and examines the potential environmental benefits of marine reuse and material recycling of fishery-related plastic waste at the Soten?s marine recycling center (M?VC). The marine environment faces significant challenges due to littering, where abandoned, lost, or otherwise discarded fishing gear constitutes a major source of both ghost fishing and plastic pollution. Through a literature review and analysis of the polymers polyethylene (PE), polypropylene (PP), and polyamide (PA), the study evaluates how circular resource management impacts fossil resource consumption and microplastic formation. Previous results show plastic materials in the marine environment gradually fragment into secondary microplastics through a combination of UV radiation and mechanical abrasion.
Virkets formförändring och dess betydelse vid postning :
The purpose of this thesis was to create a saw pattern program for the sawmill industry. I have chosen to focus on the module that describes the shrinking on the wood. There are several theories about how the wood deforms by shrinking. Several hypotheses were simulated in the program and after testing them I decided to use only one of them (hypothesis C).
The program is written in Visual Basic .NET and I choused that program language because it
is easy to do changes in the layout. Another great advantage in Visual .Net is that you can mix different languages in the same program.
Torkklimat under byggproduktion : En kvantitativ studie baserad på klimatdata och litteraturstudier
En utmaning under produktionen är uttorkning av byggfukt i byggnadens betongbjälklag. Om uttorkningen försenas kan golvbeläggningar inte appliceras i rätt tid, men att arbetet forceras är inte ett alternativ, då risken finns att fuktskador uppkommer under driftsskedet. Avgörande för att uttorkningen skall fortskrida enligt plan är att torkklimatet i byggnaden är gynnsamt för uttorkningsprocessen. För att kontrollera torkklimatet genomför företaget ett omfattande arbete genom att mäta klimatet, där dataloggar på olika platser i byggnaden registrerar luftens temperatur och relativa fuktighet. Tillsammans med trendmätningar i betong är tanken att insamlad data skall ge en bild av hur uttorkningen fortskrider.
ALTERNATIVA ASFALTSBELÄGGNINGAR : Möjligheten att använda icke petroleumbaserade bindemedel
This report investigates the possibility to use non-petroleum based adhesive (biobitumen) in asphalt. The main reasons for replacing bitumen are the fact that oil prices are rising, the threat of peak oil and the fact that the asphalt industry is becoming more environmentally friendly.The main purpose of this report is to investigate whether there are any non-petroleum based adhesives on the market. If so, how can they be used? The questions covered are:? Are there any other alternative asphalt coatings available?? Can bio-oils be used in asphalt?? If the bio-oils can be used, what are the details their properties?? How does a cold climate affect the bio binders?? What is the Swedish asphalt industry?s opinion about bio asphalt?The project was concluded through literature studies, consultations with people in the asphalt industry and through several interviews.The conclusion of this report is that there are some existing non-petroleum based adhesives on the market. They are mainly used for bike paths, sidewalks and parkareas.
handel med utsläppsrätter : en del av lösningen på koldioxidproblematiken?
In Rio De Janeiro, 1992, was the first document signed that meant a responsibility for industrial countries to decrease their emissions, United Nations Framework Convention on Climate Change (UNFCCC). Thirteen years later was the first legal binding document signed, the Kyoto protocol, and for the first time industrial countries all over the world was bound to decrease their emissions on greenhouse gases. Within the framework of this commitment, three flexible mechanisms (Clean Development mechanism, Joint Implementation and Emission trading) were introduced with the function to reduce the economical costs of the commitment. The flexible mechanisms Emission Trading (ET) is what this report is about.The report starts with a description of carbon dioxide and it?s effect on the environment, thereafter comes a background review of the national agreements who lies as a ground to the implementation of emission trading as a management control measure in Sweden and the rest of the world.Keywords: United Framework Convention on Climate Change, Kyoto protocol, Flexible mechanisms, Emission trading, carbon dioxide .
Effekten av klimatförändringar påkontrollbehovet av åkerogräs
With a changing climate, we can expect higher temperatures and more precipitation in Sweden.As the temperature increases, new weed species are expected to migrate in from more southerlylatitudes, resulting in requests for new techniques for weed control. In addition, we might see agreater number of weed species and higher biomass production due to increased concentrationof CO2 in the atmosphere.Increased understanding of the biology of specific weed species will become more importantin future weed control. This will help to control the weeds more efficiently. Higher prices onpesticides and a public demand for reduced use of pesticides make growers more inclined to usemechanical weed control on a larger scale and to a greater extent prevent weed establishmentbefore sowing. A well-planned crop rotation is the most important preventive measure, whichmight also include delayed sowing, and dark harrowing and sowing.Research takes place on many levels within the weed area and several alternative methodsare being developed.
En kvalitativ studie om hur personer med utländsk bakgrund upplever att integrationen fungerar i Sverige
Abstract Aim: Since there is a lack of research based educational interventions concerning the relationship between coaches and young athletes, the aim of this study was to implement and examine the effects of sport psychology intervention for coaches in a track and field club. The research questions were: What are the effects of an educational intervention for coaches, with focus on a motivational climate, on: A) the coaches´ coaching approach B) their athletes´ goal orientation and C) their athletes´ perceived competitive anxiety?Method: The coach education stretched over two months and consisted of four two-hour lessons with focus on motivational climate, goal orientation and sport anxiety. Six coaches (three females, three males), aged 38-52 (M=44.33 years, SD=4.84) and their 59 athletes (27 males and 32 females) aged 12-14 (M=13.10 years, SD=0.82), participated in the study. A control group of 35 athletes (10 males and 25 females), of the same age (M=13.46 years, SD=0.70) and with similar demographic data, was also recruited.
En förändrad värld, en omdanad säkerhet? - En studie om klimatförändringars effekt på svensk säkerhetspolitik
The concept of national security has been a matter for debate during recent years, especially in academic fields. Criticism has surfaced since the end of the cold war, directed towards the traditional perspective's dogmatic focus on armed threats and interstate war. Questions concerning an oncoming paradigm shift have been raised, regarding a widening of the security agenda among national states to also include alternative threats, such as environmental hazards. In this thesis, the focus lies on the effects that climate changes have caused in the Swedish national security agenda during the last 15 years. Swedish policy documents show that there have been some major changes, not only the widening of the security agenda but the entire security domain seems to have changed.
Prototyputveckling av digitalt styrsystem för torkskåp
Nimo Verken AB is the leading producer in the Scandinavia of drying cabinets. The construction has, with small changes, been the same since the 70s with a thermostat and a timer as controlling system. There was a wish to develop a modern cabinet which showed remaining time on a display and with energy saving functions.In this report we go through how it is possible to implement a digital controlling system, where remaining time is shown on a display and where it is possible to choose a preset ?program?.The report first presents the fundamental theory for a PIC, where we describe the different registers, how interrupts are handled, the internal clock function and how data is sent to control the different parts of the construction.Next the report presents and describes the new hardware that is needed, such as the encoder, the temperature sensor and the display.After the theory we describe how the program in the PIC may be drafted. Last in the report we have the result of the tests of the temperature variations and the accuracy of the time..
Potential för värmeåtervinning från mjölkkylanläggningar
The present climate discussion has made energy efficiency an interesting topic. Saving energy does
not only help the climate but also saves money for the energy consumer.
The purpose of this thesis was to examine the potential of heat recovering from milk cooling. Two
milk farms, one with voluntary milking system, VMS, and the other with conventional milking system
was used to measure interesting temperatures and electricity consumptions. The numbers were used
both to do theoretical calculations and to construct a SIMULINK model.
To calculate the potential for heat at milk farms theoretical calculations were made in MATLAB using
a reference farm with different combinations of heat recovery and pre cooling. The farm was
assumed to keep a dwelling house with the annual heat consumption 18165 kWh.
