Förslag till vägbro vid Hössnamotet - ? Konceptframtagning och kontrollberäkning av bro över väg 40

Göteborg Energi AB är ett bolag med höga ambitioner att säkerställa ett stabilt distributionsnät för sina kunder. Med ett säkerställande följer åtgärder i form av beräkningar för komponenter som transformatorer av olika märkeffekt, hög- och lågspänningssäkringar och andra kritiska skyddsanordningar som t.ex. reläskydd. Vid ett flertal tillfällen under de senaste åren har det uppmärksammats en problematik där ett fel i lågspänningsnätet har löst ut anslutande transformator. Felet har grundat sig en svag selektivitet mellan transformatorsäkring och lågspänningssäkring.

Analys av spänningsstabilitetsberäkningar i det svenska elsystemet

Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.

Immunohistochemical detection of thymidine kinase 1 in canine mammary tumors and lymphomas

The dog has often served as a model animal for humans in scientific studies. This is due to the fact that dogs are susceptible to a wide range of diseases which also affect humans. One example is cancer, a condition that affects dogs as well as owners. Neoplastic diseases account for 18-23 % of all deaths in dogs (Bonnet et al., 2005 and Jagielski et al., 2002). Mammary tumor, or tumor of the breast, is the most common tumor form in intact dogs and women (Im et al., 2013). Mammary tumors originate in the udder, and are classified according to their histological characteristics.

Val av fönster - En Multikriterieanalys

Fönster blir idag en allt viktigare del av en byggnads klimatskärm. Det ställs därför krav på olika funktioner vilka måste uppfyllas oberoende av fönstertyp. Då glas blir vanligare i moderna konstruktioner ställs det högre krav på värmeisolerande förmåga. Cirka 35 % av en byggnads värmeförluster sker genom fönster. Detta ställer krav på tillämpning av energieffektiva fönster vid ny- och ombyggnad. Underhåll av fönsterkonstruktionerna är en oundviklig detalj och måste ske någon gång under en byggnads livslängd.

Morfologisk och kemisk beskrivning av en svensk rabarbersamling (Rheum raponticum L.) :

SAMMANFATTNING Mitt examensarbete utgör ett led i Nordiska Genbankens (NGB) uppgift att skapa en nordisk s.k. ?core collection? av rabarber, Rheum rhabarbarum L. Samlingar finns även i våra nordiska grannländer Norge, Finland, Danmark och Island. I Sverige har ett insamlingsarbete av rabarber pågått under åren 2002 och 2003 för att komplettera en äldre samling.

Effekter av gödsling i äldre tallbestånd på renbetesväxter i fält- och bottenskikt :

Reindeer husbandry and Forestry are both area related industries and will in big extent use the same lands. Conflicts often arise because of that the industries have different interests. Many of the activities done by the forestry influences the reindeer husbandry in an undesirable way, simultaneously as the reindeer husbandry activities can have negative consequences for the forestry. One such forestry activity is fertilization. It was during the 1960´s forest fertilization began to be practiced and the reason was that the increase in growth that the fertilization gave could be able to cover for the future shortage in wood many feared. During the 1970´s when the fertilizing activities were most intensive about 200 000 ha was fertilized annually.

Om fototextpoesi : Läsningar av mötet mellan fotografisk bild och poetisk text

What is the relation of image and word, of sentences and pictures? What kind of message does this combination produce when juxtaposed on a single material plane? And how do we read its ?infinite? relation? These are the questions at the center of this inquiry. My main interest concerns the exact nature of the relation between photographic images and textual elements of poetic language when these are juxtaposed in what I call Phototext poetry.The thesis calls into question the conventional reading habits of the conjunction of photographs and texts, and seeks to understand the more complex connections intrinsic to the relation image/word and its material and perceptual play in poetic works. Does a text always ?anchor? the multiple meanings of an image, as Roland Barthes argues? What if the alterations of an image could ?anchor? certain fractions of a poetic, polysemantic textual construct? Is a photograph indifferent to the visual, material permutations of texts that certain contemporary poetic practices produce?I discuss phototextual works and collaborations of various kinds, from Molin fontän [?Molin?s fountain?] (1866) over classic surrealist poetry to language-oriented writing.

Värdekedjeanalys av returflöden på Scania : Fallstudie på marknaderna i Sverige, Tyskland och Benelux

Today Scania give a high priority to the continuous improvements on the quality of their vehicles. To follow up the flaws in product quality, which are recognized by the repairs at the local workshops, material requests are carried through to be able to analyze the defects at the plant in Södertälje ? in purpose to improve the product quality. The material requests are also carried through to compensate the workshop for their expenses and to check that they are working according to the company?s warranty manual.Due to local routines and different distribution structures at the different markets the lead times and the costs caused by the flow of material are hard to estimate.

Landvinning : scenarier för efterbehandling och gestaltning av Aitikgruvan, Gällivare

Open pit mining creates huge amounts of tailings and waste rock deposits. Due to it's content of sulphide minerals, predominantly pyrite (FeS2), there is a risk of oxidation and formation of acid water containing heavy metals, known as Acid Rock Drainage (ARD). To prevent the process of oxidation, the tailings and waste rock have to be reclaimed. The most commonly used methods of reclamation are a coverage of water or soil. Mining also results in a large-scale interference in the landscape that will make an eternal change of its appearance.

Den goda platsen : om varför vi tycker mer om vissa platser än andra

How can man´s place preferences be explained? What aspects influence our experience of place? This essay attempts to define a good place to be drawing from sources of environmental psychology as well as other landscape theories and relating these findings to the landscape architect?s field of work. Physical place properties, like physical elements and their juxtaposition in space are examined in relation to place preferences as well as psychological properties, such as place attachment and place identity due to cultural or social aspects.There are strong cross-cultural similarities in our place preferences but there are also some differences. Natural elements, like trees or water, are widely preferred over man-made ones, like buildings, roads or fences.Man seems to be sensitive for the balance between different place characteristics, like the balance between ?soft?, natural, elements and ?hard? man-made ones or the complexity versus the legibility of place.

English Arts and Crafts gardens and how they can be modernised in Sweden

The aim with this thesis was to investigate what characterises an English Arts and Crafts garden how they could be modernised in Sweden. My research was limited to 20 weeks of full-time writing and worth 30 ECTS. Through literature studies, interviews and site visits I could analyse my findings which resulted in a concrete garden design project. The Arts and Crafts was a movement that started in England during the 1880?s and evolved as a reaction towards the industrialisation. The influence came from the writings and practices of John Ruskin (1819-1900) and William Morris (1834-1896) who advocated the importance of craftsmanship. The Arts and Crafts movement also became a ?recipe for life? and was associated with a healthy and morally pure way of living.

Inkongruenta styrmodeller: En fallstudie av reparation och underhåll i ett industriföretag

In theory, the management control of maintenance functions is described as problematic due to the nature of the work performed in the unit. The purpose of this thesis is to examine these predicted problems in practice. Further,the thesis aims at identifying how these control problems may affect the relationships between the maintenance department and its internal customers. A case study has been conducted in one of Sweden?s largest industrial companies to investigate the said control problems in practice.

Svarte Mosse - en stadsdelspark i Göteborg :

Sammanfattning Park och Naturförvaltningen i Göteborg har tagit fram en parkplan för Biskopsgården där man pekar på en möjlig utveckling av närområdet runt sjön Svarte Mosse. Mitt mål med detta examensarbete har varit att utifrån en förståelse för de lokala förhållandena utveckla ett program med kriterier för hur området skulle kunna utvecklas samt göra ett förslag på gestaltning. Efterforskningar bland olika källor gav ett generellt svar på vad som är en bra park. Genom att studera statistik, dagstidningar och prata med boende i stadsdelen så konstaterar jag att det karaktäristiska för Norra Biskopsgården är resurssvaghet, trångboddhet, hög otrygghet och en stor andel unga. Detta tror jag sammanfattningsvis gör utemiljön viktigare i så kallade utsatta områden. Jag valde att arbeta med ett grönområde som angränsar till en typ av stadsstruktur som har blivit kraftigt kritiserat för utemiljön. Därför valde jag att göra en bakgrundstudie av modernistiska förorter.
