Land Use Scenarios for Greater Copenhagen: Modelling the Impact of the Fingerplan
Christian FERTNER,Gertrud JRGENSEN,Thomas Sick NIELSEN
Journal of Settlements and Spatial Planning , 2012,
Abstract: Urban planning and development in Denmark can be characterised by a relatively strong planning framework. Land use scenarios based on empirically derived dynamics of urban growth are practically never applied. However, modelling approaches do offer a methodology to explore the pressures in an urban region, as well as an approach to understand urban development patterns outside the ‘spatial masterplan’. In this context we will present the results of a modelling exercise addressing future land use change in the metropolitan area of Copenhagen, Denmark, and the impact of the current regional planning framework, the “Fingerplan 2007”. We test three policy scenarios and analyse different effects on urban growth by using the Metronamica model from the Dutch-based Research Institute for Knowledge Systems (RIKS). We analyse the possibilities to elaborate a practical and useful outcome within a relatively short period of time. The set-up and the results were discussed with a few experts from the Danish Ministry of the Environment and its value as discussion input recognized. The approach offers a lot of possibilities to discuss urban growth and spatial planning policies, even in a country with a strong planning framework as in Denmark.

Abstract: In total, we analyzed 39 meat quality traits and identified eight genome-wide significant QTL peaks in four regions: one on chromosome 3, two on chromosome 6 and one on chromosome 16. At least two of the QTLs do not appear to have been detected in previous studies. On chromosome 6 we identified QTLs for water content in M. longissimus dorsi (LD), drip loss in LD and post mortem pH decline in LD. On chromosomes 3 and 16 we identified previously undetected QTLs for protein content in LD and for freezing and cooking loss respectively.We identified at least two new meat quality trait QTLs at the genome-wide significance level. We detected two QTLs on chromosome 6 that possibly coincide with QTLs detected in other studies. We were also able to exclude the C1843T mutation in the ryanodine receptor (RYR1) as a causative mutation for one of the chromosome 6 QTLs in this cross.Since the first Quantitative Trait Locus (QTL) analysis in pigs was published in 1994 [1], QTL analyses have been widely used to identify chromosomal regions harbouring genes for various complex traits in the pig such as growth, carcass composition and meat quality [2]. Meat quality traits have been studied before using crosses between Wild Boar and Large White [3,4], Meishan and Yorkshire [5], Meishan and Large White/Landrace [6], Duroc and Landrace/Yorkshire [7], Berkshire and Yorkshire [8], Iberian and Landrace [9], Pietrain and Meishan and Wild Boar [10], and between Duroc and Berlin Miniature pig [11].In this study we used a cross between Finnish Landrace and Swedish Hampshire set up by the Swedish breeding company Quality Genetics, as a combined intercross/backcross design. Landrace has been used in several QTL crosses before, but so far the Hampshire breed has not been used in any QTL intercross which provided an opportunity to detect specific QTL alleles that have been selected in this breed. Landrace and Hampshire pigs differ in a number of traits including coat colour, body composition, ferti
Endomycorrhizal Fungi and Opuntia ficus-indica Seed Germination on a Lunar Regolith Simulant  [PDF]

Advances in Microbiology (AiM) , 2014, DOI: 10.4236/aim.2014.410068
Abstract:

Endomycorrhizal fungi play an important role in the survival of plants on poor soils. Planting seeds into lunar soil at a lunar colony will be a challenge for seeds of any plant. The seeds will need a special microbial “tool kit” that will help them germinate and the young seedlings establish themselves. In this study, seeds of the prickly pear cactus, Opuntia ficus-indica, were chosen to examine the presence of fungus spores in the soil, inside the seeds and after germination in the rhizosphere, roots and other tissues of the young seedlings. The nutrient poor lunar regolith simulant JSC-1A was used as autoclaved or untreated growth medium. The mycorrhizal fungus Trichoderma viride was predominantly identified on the roots of new seedlings. This fungus also demonstrated the strongest effect on the germination rate of the seeds in comparison with other fungi isolated from the rhizosphere of Opuntia plants. T. viride was not detected within seeds and also not within seedlings, besides the root tips, whereas an arbuscular mycorrhizal Glomus species was seed-borne and present throughout most of the seedling. A close association between T. viride and a Glomus species associated with O. ficus-indica

Is the tide turning against breast screening?
Karsten Jrgensen
Breast Cancer Research , 2012, DOI: 10.1186/bcr3212
Abstract: The rationale for breast screening with mammography is deceptively simple: catch the cancer early and reduce mortality from the disease and the need for mastectomies. But breast cancer is a complex disease, and complex problems rarely have simple solutions.A key question is if screening can prevent metastasis, as this would reduce breast cancer fatalities. Another is if the screen-detected tumours that previously required a mastectomy are now small enough to allow breast conserving surgery. The fundamental premise for both objectives is that screening must reduce the incidence of advanced breast cancer. Whether such a reduction occurs in a long-running, organized, population-based breast screening programme is what Joost Nederend and colleagues explore in their study from The Netherlands [1].Other researchers have questioned whether breast screening reduce the number of advanced cancers [2,3]. A claimed reduction in breast cancer mortality [4-6] as well as a reduction in the use of mastectomies [7,8] have also been called into doubt in studies of population-based breast screening. In addition, the detection of cancers that would otherwise not have developed into clinical, symptomatic disease (overdiagnosis) is now recognised as an important harm, also for invasive breast cancer [9,10].A recent systematic review of incidence trends in seven countries with at least seven years of screening [2] found that breast screening has not fulfilled its promise of fewer advanced breast cancers. It included The Netherlands, but not data from before organised screening was introduced in the late 1980s. Including data from 1980 to 2008 is a strength of the new study, as it allows reliable estimates of both pre- and post-screening incidence trends of advanced breast cancer. If the background incidence was increasing prior to screening, but stable during the screening period, screening may have prevented a further increase in advanced breast cancer. This seems not to have happened, e

A Blueprint for Destruction: Eco-Activism in Doctor Who during the 1970s
Dolly Jrgensen
Ecozon@ : European Journal of Literature, Culture and Environment , 2012,
Abstract: This article analyzes the television science-fiction show Doctor Who as a cultural forum within the context of British eco-activism of the 1970s. It examines four serials which aired during the 1970s during the first wave of eco-activism in the UK: "The Green Death" (1973), "The Invasion of the Dinosaurs" (1974), "The Seeds of Doom" (1976), and "Nightmare of Eden" (1979). Two environmentalist concerns-pollution and species conservation-put forward by the early British eco-activist movement as underscored in texts such as The Blueprint for Survival from 1972 are evident in these serials. While affirming the validity of some elements of environmentalist concerns, each serial also proposes that the ends do not always justify the means. The Doctor, although a supporter of eco-activism, rejects seemingly utopian approaches to reset the Earth's ecosystems. Rather than presenting viewers with a guide to sustainability, these Doctor Who serials offer dystopian visions of future realities steeped in ecological transgressions – these are the blueprints for destruction.
Folk Narrative and the History of Culture
Lene I. Jrgensen
Folklore : Electronic Journal of Folklore , 2007,
Abstract: The article illustrates that the texts and perceptions of The Old FolkBallads of Denmark reflect traces of different eras. Ballads about the medieval King Valdemar II and his queens Dagmar and Bengerd (Infanta Berengária of Portugal) exemplify this. The formations of the narrated figures are medieval but the formations of the narrated plots are from the Renaissance and concern the arrangement of marriage. Their references concern both the traditional narration of the Middle Ages and the social realities of the Renaissance. The public attention to the ballads increased in the Romantic era. Folk narrative researchers launched the master-narrative about the formation and transmission of the ballads from the medieval time of their figures to the Renaissance telling-time of their plots. However, this master-narrative about the ballads as a phenomenon covers for the recognition of their narratives. Today, the ballads are receiving new attention through a canon for the primary school and in other ways. The master-narrative is reused and renewed in order to respond to the cultural conflict caused by the process of globalisation. The aim is to shape a new unity of the population that now includes both the “old” and “new” Danes. This contradicts with differentiated experiences of one of the two main groups within the population, introducing new alternatives for recognising and identifying with the narrated figures and plots in account.
Pigs and Pollards: Medieval Insights for UK Wood Pasture Restoration
Dolly Jrgensen
Sustainability , 2013, DOI: 10.3390/su5020387
Abstract: English wood pastures have become a target for ecological restoration, including the restoration of pollarded trees and grazing animals, although pigs have not been frequently incorporated into wood pasture restoration schemes. Because wood pastures are cultural landscapes, created through the interaction of natural processes and human practices, a historical perspective on wood pasture management practices has the potential to provide insights for modern restoration projects. Using a wide range of both written and artistic sources form the Middle Ages, this article argues that pigs were fed in wood pastures both during the mast season when acorns were available and at other times as grazing fields. Pollarded pedunculate oak ( Quercus robur) likely dominated these sustainable cultural landscapes during the medieval period.
Scientific results from the deepened Lopra-1 borehole, Faroe Islands: The regional distribution of zeolites in the basalts of the Faroe Islands and the significance of zeolites as palaeotemperature indicators
Jrgensen, Ole
Geological Survey of Denmark and Greenland Bulletin , 2006,
Abstract: The first maps of the regional distribution of zeolites in the Palaeogene basalt plateau of the Faroe Islands are presented. The zeolite zones (thomsonite-chabazite, analcite, mesolite, stilbite-heulandite, laumontite) continue below sea level and reach a depth of 2200 m in the Lopra-1/1A well. Below this level, a high temperature zone occurs characterised by prehnite and pumpellyite. The stilbite-heulandite zone is the dominant mineral zone on the northern island, Vágar, the analcite and mesolite zones are the dominant ones on the southern islands of Sandoy and Sueuroy and the thomsonite-chabazite zone is dominant on the two northeastern islands of Vieoy and Boreoy. It is estimated that zeolitisationof the basalts took place at temperatures between about 40°C and 230°C. Palaeogeothermal gradients are estimated to have been 66 ± 9°C/km in the lower basalt formation of the Lopra area of Sueuroy, the southernmost island, 63 ± 8°C/km in the middle basalt formation on the northernmost island of Vágar and 56 ± 7°C/km in the upper basalt formation on the central island of Sandoy.A linear extrapolation of the gradient from the Lopra area places the palaeosurface of the basalt plateau near to the top of the lower basalt formation. On Vágar, the palaeosurface was somewhere between 1700 m and 2020 m above the lower formation while the palaeosurface on Sandoy was between 1550 m and 1924 m above the base of the upper formation.The overall distribution of zeolites reflects primarily variations in the maximum depth of burial of the basalt rather than differences in heat flow. The inferred thinning of the middle and upper basaltformation from the central to the southern part of the Faroes is in general agreement with a northerly source area for these basalts, centred around the rift between the Faroes and Greenland. The regional zeolite distribution pattern is affected by local perturbations of the mineral zone boundaries that reflect local differences in the temperature, perhaps related to the circulation of water in the underground. The zonal distribution pattern suggests that these temperature anomalies are in part related to NW–SE-trending eruption fissures or zones of weakness separating the present islands and are subparallel to transfer zones in the Faroe–Shetland Basin. Both the regional and the local distribution of zeolite assemblages are probably a reflection of the basic volcanic-tectonic pattern of the Faroe Islands.
