Oslo's Farewell to Urban Sprawl

Sustainable mobility has been an important concern in urban planning and development in Oslo Metropolitan Area since the 1990s. The period has been characterized by concentrated and compact urban development, especially within the municipality of Oslo. This has contributed to a reduction in growth in car traffic. Analyses of selected land use and transport plans and policy documents, professional journal articles and interviews with key actors show that there has been a high degree of consensus about this spatial development strategy. Considerable investments have been made in public transport as well as in road development; the former based on broad consensus. Road capacity increases have been contested among professionals but widely supported by politicians.     

Moving peoples,changing diets: isotopic differences highlight migration and subsistence changes in the Upper Mun River Valley,Thailand

The dramatic growth of dietary isotope studies in archaeological literature attests to the significant potential this technique has for shedding light on past societies. Human diet reflects complex, inter-linked factors such as status, cultural preferences or environmental constraints on food production. In this study dietary isotope analysis is used to examine the human skeletal remains from Ban Non Wat, northeast Thailand. The study aims to use isotopic data to give insight into patterns of migration and subsistence strategy during prehistory. Ban Non Wat is the most comprehensively excavated site in the Upper Mun River Valley (UMRV), and understanding of prehistoric society in this area is crucial to answering questions of how social complexity arose in the region. Carbon isotope analysis has highlighted migrant individuals invisible to strontium isotope analysis and shown links between unusual burial practice and differences in diet. Results also indicate that diet changed substantially through time, with more reliance on rice in the Bronze Age, correlated with an increase in social differentiation. There is a move away from reliance on rice agriculture in the Iron Age, a time when oxygen isotopes show that environmental conditions were becoming drier, possibly resulting in rice agriculture becoming less viable.     

Capillary seal capacity of faults under hydrodynamic conditions

Many fault bound traps are underfilled despite the top seal capacity being secure. The hydrocarbon sealing performance of faults themselves can be compromised either by mechanical or capillary process. Capillary process can be important either due to juxtaposition or to fine‐grained clay or cataclastic material within the fault zone itself. There is debate about how important each of these mechanisms is over geological timescales of hydrocarbon trapping. Recent work has provided insights into fine‐tuning capillary‐related fault seal calibration methodologies. Over the last 15 years, vigorous scientific debate with multiple published laboratory experiments and modelling studies has led some researchers and industry technologists to theorise that for water‐wet conventional hydrocarbon reservoirs, the relative water permeability in the reservoir (towards the top of the hydrocarbon column) may become very small, but in practice never reach zero. While not advocating for either side in this debate, the importance of accounting for hydrodynamic conditions regardless of the capillary sealing mechanism is demonstrated. Additionally, it is noted that nonzero relative water permeability has implications on how a seal's capillary threshold pressure for the nonwetting hydrocarbon phase is estimated from field data. In the particular case where there are pressure differences between unproduced hydrocarbon reservoirs on either side of a fault, then the hydrocarbon saturation must be discontinuous across the fault. For hydrocarbon leakage to occur across the entire thickness of the fault zone, the hydrocarbon pressure must exceed the threshold pressure on the side of the fault zone with the highest formation water hydraulic head. This approach to estimating across‐fault pressure difference will result in an improved calibration data set used for predrill estimation of capillary fault seal capacity.     

Kirkenes: An Industrial Site Reinvented as a Border Town

Abstract

1 1. This is a significantly revised version of an article published in Nyseth and Granås 2007 “Place-reinvention – Dynamics and Governance Perspectives”, Stockholm: Nordregio. This article analyses the transformation of Kirkenes, a small town on the Russian–Norwegian border, from an industrial town to a border town. Kirkenes was established as a harbour for an iron-ore mining venture in what today is the municipality of Sør-Varanger. This industry closed down during the 1990s. The article describes how Kirkenes has been transformed within “bordered” relationships of civic society, business and a combination of high-level and local political activities. Being a border town and a centre in the Barents Region is the hegemonic narrative of today. The manifold transformations have led to a situation where Kirkenes has become “Russianized”, though local actors struggle with how to handle this aspect of local development and the meaning of the place. The article also investigates to what degree the transformations have changed local identity. The focus is on how identities are dealt with, whether they are seen as immanent and essential cultural traits, or as something that tends to be changed and adapted to the situation. Based on the concept of narrative identities, there are reasons to believe that there are strong identities based on both public narratives relating to local history and nature and metanarratives about globalization and cross-border communities.     

A Newly Acquired Ancient Ship-model in Kassel, Germany

Study of the small clay ship-model T832 in the Kassel Museum suggests that it is an instructive document bearing on ancient Greek maritime history and folklore. A preliminary dating that has had to rely on iconographic and literary sources gives an origin in the 6th or 5th centuries BC and a tentative identification as a small coastal warship. Some suggestions as to the purpose and use of the model are discussed.
