Påsköns stenstatyer, moai : Vilket genus representerar de?
Abstract.The question in this analysis is which gender moai, the big statues on Rapa Nui, represent. My hypothesis is that they have developed from visual symbols to metaphores in mythologies from an polynesian context. That these statues were symbols for human origin and creation of ancestors ideological power, and gods in consideration male gender. In the long isolation, in both time and space, the mytologies in Rapa Nui was changed, and the pictures got a new meaning. These changes depended on clearing of wood and big trees and the following difficult situation in farming.
Culhwch & Lúthien : Keltisk mytologi i J. R. R. Tolkiens sagovärld
This study investigates in what respects Celtic mythology influenced J. R. R. Tolkien when writing the sagas incorporated in the mythopoeic compilation of The Silmarillion. Through narrative and comparative analysis, stories from the Irish prose collection Lebor Gabála Érenn, as well as the Welsh medieval manuscript Mabinogion, are collated to the tales of The Silmarillion in order to illuminate possible influences.
Energieffektivisering av Villor : Finns möjligheten till Passivhusstandard för befintliga bostäder
The climate change the earth today has to face is no longer a global problem when every individual has a responsibility to act. The residents in Sweden have no understanding how their energy consumption affects the environment, nor what measures can be taken to reduce the energy consumption.The use of the energy in new Buildings is considerably lower than in the older ones as conditions have improved and the requirements have been more stringent. As most of the buildings in the future have already been constructed it´s important to take every opportunity for energy efficiency and rebuilding of available buildings will become a significant act. Reconstruction of a building contributes generally to both a reduced individual and a reduced total energy use, while new constructions only keep a low individual energy use but a increase the total energy use. For this reason we present the opportunities for reconstruction, mainly to reach the standards for a passive house..
Miljödiplomeringens betydelse för små och medelstora företag
I denna studie analyseras Göteborgs kommuns miljödiplomeringsmodell, dess tillämpning,problem och möjligheter. Syftet var att studera vad företag och revisorer accentuerar på, vilka problem och brister som förekommer samt hur miljöprestanda och miljökommunikation uppfattas i certifierade respektive diplomerade företag. Ett annat syfte var att studera vilka orsakerna är bakom att en del diplomerade företag hoppar av sitt diplom och andra avvaktar med att diplomera verksamheten..
Termohalin cirkulation i Nordatlanten
Den termohalina cirkulationen är en global havscirkulation driven av densitetsskillnader, som gör att varmt vatten transporteras mot polerna och kallt vatten mot ekvatorn. Densiteten påverkas av temperatur och salinitet (och tryck, som vanligtvis ignoreras). Därför heter cirkulationen termohalin. Saliniteten minskar när vatten tillförs genom nederbörd, havsissmältning eller landavrinning. Saliniteten ökar genom avdunstning och isbildning.
Gravitationslinser
Gravitational lenses are unlike ordinary optical lenses, a phenomenon corrupting our optical view of the cosmos. When we look out intospace we see celestial bodies lying with astronomical distance from Earth. There is no guarantee that what we see out there in space is actually there where we are observing it, and it may be that we see multiple images of the same star! Studies have shown that thenumber of distorted images of an n-mass (n > 1) plane lens can not exceed 5(n -1) for lighter lenses or 5n for more massive lens. This mathematical thesis covers gravitational lensing and their properties that distort light rays coming towards us from distant celestial bodies. In addition of gravitational lensing, its properties and the proof of the maximum number of distorted images, a bigger part of this work even cover two very interesting mathematical tools - the so-called Schwarz function and Bezout theorem..
Stegvist införande av miljöledningssystem - en lämplig modell för små och medelstora företag.
Mindre företag upplever ofta en del hinder vid införande av miljölednings-system såsom ISO14001 och EMAS. Standarderna uppfattas som byråkratiska och införandet tar för mycket resurser i anspråk, i form av både tid och pengar. I Storbritannien har en ny standard för miljöledning tagits fram för att bättre passa framförallt mindre företag. Standarden, BS 8555,erbjuder ett stegvist införande av ett miljöledningssystem, med möjlighet att få intyg på vägen mot ISO 14001 eller EMAS. Företagen kan också välja att stanna på en lägre nivå än ISO14001 för en längre period..
Aerosolers dygnsvariationer och långväga transporter
This work aims to obtain information on diurnal variations of aerosol concentrations in thecity of Lund (Sweden) and trying to locate the origin of the aerosols long distance transports.The study shows that the aerosol concentrations varied quit strongly over the entiremeasurement period, reflecting air masses of different degrees of pollution, mainly as a resultof the diurnal rhythm of the traffics. Trajectories reveals that air masses originated inSoutheastern and Eastern Europe contains higher aerosol concentrations compared to other airmasses..
Extraterrestrisk och terrestrisk kromrik spinell i fanerozoiska kondenserade sediment
This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.
En studie av landskapsindex för kvantifiering av rumsliga landskapsmönster
Syftet med uppsatsen är att utvärdera två landskapsindex: ett formindex som beräknar formen för varje markanvändningsyta ( eng. "patch"); ett diversitetsindex, som beskriver de olika markanvändningarnas relativa utbredning. Formindexet beräknas på två olika sätt, beroende på om dess storleksberoende inkluderas eller ej. Utvärderingen körs för ett landskap på cirka 50 km2, men även för tre mindre områden i landskapet: åkerbygd, mellanbygd samt skogs-bygd. Samtliga områden jämförs sedan i två olika skalor, flygbild respektive satellitbild..
Bredspridning av grönmassa :
There are a great possibility to shorten the time between mowing and preservation by spreading of ley crops in connection to the conditioning. In this case the cellular respiration (the plants breeding that consume sugar until the crop is ensiled) should not continue as long and the forage will perhaps get a higher nutritional value. The capacity of the next machine could also be higher because the rake gives swaths with a lot of material. There is also a possibility that spreading of ley crops gives the material a more homogeneous content of dry matter and that gives a reduced growth of clostridium. This is particularly important when the method of harvest doesn?t include any mixing of the material like it does with a round baler or silagewagon.
Till för medmänniskan Om medmänsklighet utifrån Martin Buber och Gustaf Wingren
This is a study of humanity about the meetings we have with one another. I write about this subject out of the perspective of Martin Buber and Gustaf Wingren. As I enter this area and begin the writing a few questions are being developed, such as:? Why do we as humans have the need to meet each other?? ?What happens with us when the meeting is absent?? ?What does it mean to love your fellow man or woman?? ?What helps or destroys our possibilities to meet each other?? Buber talks about Me and You and the aim of the meeting we have with each other. When we meet each other it generates a responsibility against each other.
Miljöinformation från teori till praktik.
The purpose of this paper is to investigate the process of transferring information from science to "the field" of environmental protection in Sweden. I have studied four Swedish environmental organizations, Greenpeace Nordic, WWF Sweden, the Swedish Society for Nature Conservation and Friends of the Earth Sweden to see how they search/get information. I have also studied the Swedish Environmental Protection Agency and its role as sender of information, since it is the authority which is responsible for environmental information in Sweden. I have used information and communication theories as a help to analyse my results. While working on this paper I realized that my methods were not the best.
Vinkelfelet i mätkretsens påverkan på riktade jordfelsskydd
Utfört examensarbete undersöker vinkelfelet i mätkretsen för riktade jordfelsskydd och hur det påverkar dess felbortkoppling. Uppkomna vinkelfel i mätkretsen kan påverka det riktade jordfelsskyddet så att verklig felström och uppmätt felström inte stämmer överens, vilket kan leda till uteblivna eller obefogade felbortkopplingar. Vattenfall ställer krav på att vinkelfelet får uppgå till max ±2 grader för mätkretsen. Eftersom vinkelfelet i många fall har en hög påverkan på jordfelsskyddets noggrannhet undersöks vad Vattenfalls vinkelkrav egentligen innebär. Största orsaken till vinkelfelet uppstår oftast i strömtransformatorn och därför undersöks hur mycket två strömtransformatorer med olika klassificeringar som är vanliga i elnätet påverkar vinkelfelet i mätkretsen.Jordfel är det vanligast uppkomna felet i mellanspänningsnät och dess storlek beror till stor del på hur mycket kapacitivt bidrag som finns på linjerna samt värdet på nollpunktsresistorn.
Camping : Vad, Vem & Varför!
What on earth do people see in camping? Why do they choose this compact living in their holiday? All that people in caravans who are put together in a camp site.The purpose of my study was to find out who and wy. My ethnographic study in a camp site with participation observations, interviews and analysis have results in facts that show why.The most common camper is the house owner with average income. And the choice of the camp site depend on the security and the service that the camp site offered. The camp site was controlled and the campers controlled each other.
