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..

This study aims to investigate how participants in a companys traineeprogram describe that the programmes educational tasks has prepared them for their future work. The study also examines how participants perceive that they have developed skills that are specifik to their profession and how they became part of a community. The following questions were formed to make it possible to investigate the purpose further; ?Do the participants feel that the interaction within the trainee group has promoted their learning??, ?How does the participants describe the training elements in relation to their development of competencies that they use in their professional role?? and ?How does the traineeprogram contribute to the participants becoming part of a community??. This was examined by taking part of what previous research has highlighted as important for learning and socialization in relation to traineeprograms.

The aim of this study was to investigate which elements that functioned in a positive way on the natural behaviors of dairy cattle among KRAV certificated and conventional farms. The study was based on reading of earlier research and completed by interviews with farmers, animal health inspectors and consumers. The results showed us that the KRAV certificated farms used only loose housing barns and that the cattle were allowed a pasturetime of five months, or more, in one year. Our interviews with the consumers confirmed that KRAV was a well known trademark. The conventional farms were more flexible in their choice of housing systems, and used both loose housing barns and barns with the cattle tethered.

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.

Svenska elevers l?sf?rm?ga har under det senaste decenniet sjunkit och forskning visar att l?rares l?sundervisning ?r den st?rsta framg?ngsfaktorn f?r elevers l?sutveckling. Dock visar internationell forskning att det finns brister i l?rares kunskaper om vad god tidig l?sundervisning b?r inneh?lla samt p? vilket s?tt den b?r genomf?ras, vilket bland annat uttrycks genom l?rares uppfattningar om den egna tidiga l?sundervisningen. Studier som beskriver svenska l?rares uppfattningar av god tidig l?sundervisning har ej hittats av f?religgande studies skribenter, vilket f?ranleder denna studiens syfte: att ge en bild av l?rares uppfattningar av god tidig l?sundervisning i f?rskoleklass och ?k 1.

Graphic profiles are a part of companies? brand expressions. The graphical values reflect the brand values the business wants to convey. They consist of different graphic elements such as logo, company sign, colour schemes, templates, rules, fonts, pictograms, formats and references to how different graphic elements should look, for example, business cards, signs and materials for websites. This thesis aims to examine why firms choose to replace their graphic profiles by studying their underlying motivations.

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..

Syftet med denna studie a?r att underso?ka lekens betydelse fo?r barns la?rande och utveckling. Studien bygger pa? en kvalitativ metod da?r vi har intervjuat sju stycken fo?rskolla?rare.

Denna uppsats unders?ker DRT-tj?nsten Teletaxi i Odense, Danmark f?r att se hur tj?nsten f?rh?ller sig till h?llbar mobilitet och socialt h?llbar tillg?nglighet. Vidare syftar studien till att unders?ka hur resm?nster hos de boende i omr?den med Teletaxi f?r?ndrats sedan implementeringen av tj?nsten. F? studier har gjorts om DRT-tj?nster i icke-urbana omr?den och de som gjorts utg?r ofta fr?n ett ekonomiskt eller milj?relaterat perspektiv, d?r de sociala aspekterna g?llande h?llbarhet inte tas i ?tanke.

Flustret is a restaurant and an entertainment place situated by Svandammen in Uppsala. It all began in 1842 as a café serving coffee, tea, chocolate and pastry. During the years the building has had numbers of different owners. The owners of today are running Flustret in a same friendly spirit that has been characteristic from the beginning. The buldings history is now approaching an age of 165 years. Throughout the years different historical layers have been placed on top of each other, leaving a layer of patches.

The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive. The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of association analyses.

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..

Trajectories reveals that air masses originated inSoutheastern and Eastern Europe contains higher aerosol concentrations compared to other airmasses..

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.
