Peab har utvecklat vägbyggnadskonceptet SwePave för att optimera olika överbyggnadskonstruktioner med bland annat stabiliserat packat material. Denna metod går även att använda för att stabilisera jorden förgrundläggning av nya byggnader. Där stabiliserat material använts för att förstärka jorden behövs även en metod för att förstärka för de punktlaster som nedförs av stomkonstruktioner. För att f

A progressive collapse implies a structural failure initiated by a local damage which subsequently develops, as a chain reaction, into a failure of either the entire structural system, or only a part of it. The collapse of the Ronan Point building in London 1968 prompted numerous efforts to develop structural design criteria to prevent progressive collapse. Improved design procedures with the inte

There are many ways to construct a building. The designing team, structural engineers and architects, works together to find the best possible solution that will fulfill the owner’s whishes. In this process a structural system needs to be chosen. There are many factors that affect the selection of the structural system, but generally the most economical system is chosen. The factors that need to

In the 1940-ies curtain walls were introduced, i.e. brick walls that do not have any bearing function but served as a front material. Horizontal reinforcement was used in this kind of walls, partly over and under openings or, in undisturbed wall fields, every 5-6th bed joint. In this work the tensile bond strength of mortar joints repaired with an injection tool and a manual method respectively is

The aim of this study is to examine how a new area of work is emerging, and how the organization´s framework and guidelines affect the professionals´work. In 2010 a law, concerning the child´s right to be involved when a parent suffer from serious illness, was extended to give these children an enhanced protection. We also want to highlight how the professional´s works are affected of the organiza

Not long ago large cash holding in balance sheet would not be recommended. As we know, large cash in hand means the companies less invest in new projects and extend their business. However, the recent research reveals that U.S companies hold more cash than before, and the financial strength might have strong relationship with the performance. Especially during the financial crises, those who reser

Syftet med studien är att undersöka ifall något samband mellan fondprestationen och de organisatoriska fondegenskaperna existerar. Studien ska bidra till en ökad förståelse för hur olika fondegenskaper i fonder kan komma att påverka en fonds prestation. Mer exakt så syftar studien till att kunna förklara relationen mellan en fonds prestation och antalet fonder i fondfamiljen, antalet personer invo

Abstract Value at Risk (VaR) is a simple, transparent and consistent measure that summarizes all sources of downside risk. VaR has gained acceptance in the banking industry in accordance to Basel II rules which require banks to use VaR in calculations of market risk. VaR as a risk measure is not as widely accepted in the investment industry. This thesis embraces five different VaR models to 20 equ

The Monte Sporno flysch unit consists of regularly alternating calcareous turbidites and subordinate hemipelagic clays, deposited in a basin plain environment near, but above, the calcite compensation depth (CCD). Evidence for turbidity current emplacement includes sole markings, Bouma intervals and resedimented shallow-water microfossil species in a deep-water trace fossil assemblage (Nereites ic

The trace fossil assemblages exposed at the Armorano road section in the Monte Sporno unit, Northern Apennines, Italy, occur in a turbidite sequence composed of fine-grained limestones (mudstones) and argillaceous limestones (wackestones) together with coarser grained calcareous sandstones and claystones, both turbiditic and hemipelagic. Fodinichnial vertical burrows of post-depositional origin an

The Bajocian Fuglunda Member of Eriksdal consists mostly of sand, silt and coal arranged in cycles (2-4m). Each cycle generally starts with organic-rich heteroliths at the base and further up ripple-drift cross laminated and horizontally laminated fine sand follow. The coal seams at the top of the cycles are of minor thickness. Signs of soil formation occur as coalified rootlets reaching down from

The granite massif in the Tjärnesjö area, southwestern Sweden, was deformed and metamorphosed under granulite facies conditions in late Sveconorwegian time. The intrusive is dominated by a coarse-grained, megacrystic orthoclase granite. Pb-Pb evaporation datings on single zircons from the granite yield an age of ca. 1.36 Ga, interpreted as the intrusion age. A similar age was obtained on zircons f

This study deals with the development of a subglacial cavity in a province dominated by stoss- and leeside rockridges. In the area of Järnavik, south-central Blekinge, there is a small excavation on the leeside of a bedrock ridge. The lithofacies combinations in this section contains both diamictons and sorted sediments. The diamict units are both massive and stratified. The sorted sediments are m

Summary: This is an investigation of Early Holocene water level changes based on the sediments in two bays, Sörevik and Norrevik on Senoren, an island in the Karlskrona archipelago in eastern Blekinge southeastern Sweden. This area has experienced a number of transgressions and regressions since the last deglaciation at approximately 12,600 BP. The history of the Baltic is characterized by many dr

Sammanfattning: Arbetets syfte var att göra en utvecklingshistorisk tolkning av området kring Örseryd, mellersta Blekinge. Ett 2000 x 600 m stort område ytkarterades, varefter olika enheter definierades och korrelerades med tidigare undersökningar utförda i Blekinge. Arbetet koncentrerades sedan till torvmarksområden påträffade under ytkarteringen. Tre torvmarksområden kan urskiljas inom undersöknSummary: The aim of this investigation was to study the Holocene history of a river valley near the village of Örseryd, situated in the middle part of the county of Blekinge in South Sweden. Covering 2000 x 600 m the area was investigated by survey mapping. Grain size analysis were made on representative samples and the different sediments were correlated to lithostratigraphic units defined in ear

Middle-Upper Ordovician strata are well exposed along the Kyrkbäcken rivulet in the Röstånga area of Scania. The investigated sequence dips about 40° towards the south, and comprises about 26 m of strata. It consists largely of siliceous limestones, mudstones, shales, and bentonites. The section is generally richly fossiliferous and has yielded bivalves, brachiopods, cephalopods, gastropods, grapt

Campanian sediments of the Maltesholm quarry consist of mostly coarse grained, poorly consolidated, ruditic grainstones, almost free of micrite and lime mud, with interbedded clay horizons. The main constituents of the grainstones are coralline algae and quartz. The lack of micrite and the abundance of coralline algae indicates a nearshore, shallow, high energy environment. Two different facies ma

During the last decades the municipals in Sweden has intensified their efforts to find alternative uses for the wastewater produced within the municipality. In Svalöv, Scania, a pilot-plant started in collabaration with Svalöf Weibulls AB to cultivate energy forest by wastewater irrigation. The vegetation is thus supplied with nutrious fertilazing at the same time as a purification of the wastewat

The endemic mesosaurid reptiles of the Whitehill-Irati sea in southern Africa and South America during the Permian were studied with preference for the Namibian material. To date three valid mesosaurid species have been described of which two occur on both continents. These mesosaurid aquatic reptiles were among the first evidence used to support the theory of continental drift at the beginning of

The archipelago of Svalbard is a key area for understanding the North Atlantic Caledonides. The pre-Devonian rocks of Svalbard are an assemblage of different terranes, probably juxtaposed by transpression during the Caledonidian orogenesis. Svalbard's Eastern Terrane consists of a thick (c. 18 km) succession, of Paleoproterozoic to Ordavician age, referred to as the Hecla Hoek sequence, and is
