    Palaeobiology, ecology, and distribution of stromatoporoid faunas in biostromes of the mid-Ludlow of Gotland

    Six well exposed mid−Ludlow stromatoporoid−dominated reef biostromes in four localities from the Hemse Group in southeastern Gotland, Sweden comprise a stromatoporoid assemblage dominated by four species; Clathrodictyon mohicanum, “Stromatopora” bekkeri, Plectostroma scaniense, and Lophiostroma schmidtii. All biostromes investigated in this area (of approximately 30 km2) are interpreted to belong to a single faunal assemblage forming a dense accumulation of fossils that is probably the best exposed stromatoporoid−rich deposit of the Silurian. The results from this comprehensive study strengthen earlier interpretations of a combination of genetic and environmental control on growth−forms of the stromatoporoids. Growth styles are similar for stromatoporoids in all six biostromes. Differences in biostrome fabric are due to variations in the degree of disturbance by storms. The uniformity of facies and the widespread low−diversity fauna support the view that palaeoenvironmental conditions were similar across the area where these biostromes crop out, and promoted the extraordinary growth of stromatoporoids in this shallow shelf area

    Estimation of the urban heat island for UK climate change projections

    Copyright © 2010 by SAGE PublicationsCities are known to exert a significant influence on their local climate, and are generally warmer than their surroundings. However, climate models generally do not include a representation of urban areas, and so climate projections from models are likely to underestimate temperatures in urban areas. A simple methodology has been developed to calculate the urban heat island (UHI) from a set of gridded temperature data; the UHI may then be added to climate model projections and weather data files. This methodology allows the UHI to be calculated on a monthly basis and downscaled to hourly for addition to weather generator data. The UHI intensities produced are found to be consistent with observed data.Practical application: There is overwhelming consensus amongst the scientific community that the Earth’s climate is warming. In addition to the effects of climate change the urban heat island (UHI) effect can increase air temperatures significantly in urban areas above those of the rural areas around them. The proposed methodology for calculating the UHI from a set of gridded temperature data allows the UHI to be added to climate model projections such as UKCP09 or HadRM3 and weather data files. The methodology also allows for the temporal downscaling of the UHI from monthly values to hourly data for use in building thermal simulation software

    Pollution in the open oceans: 2009-2013

    This review of pollution in the open oceans updates a report on this topic prepared by GESAMP five years previously (Reports and Studies No. 79, GESAMP, 2009). The latter report, the first from GESAMP focusing specifically on the oceans beyond the 200 m depth contour, was prepared for purposes of the Assessment of Assessments, the preparatory phase of a regular process for assessing the state of the marine environment, led jointly by the United Nations Environment Programme (UNEP) and the Intergovernmental Oceanographic Commission (UNESCO-IOC)

    The Shelter Characteristics of Traditional-styled Inuit Snow Houses

    The shelter value of snow iglus at Resolute (74 41 N, 94 54 W) in the Canadian High Arctic was assessed. After a survey of snow conditions, construction sites were chosen and two iglus were built and furnished in a traditional way. A large iglu (4.1 m diameter) contained 72 blocks averaging 23.6 kg and had a surface area-to-volume ratio of 2.21:1. A smaller iglu (3.05 m in diameter) contained 46 blocks averaging 28.2 kg and had a surface area-to-volume ratio of 1.73:1. The smaller iglu provided 75% of the large iglu's space for 76.5% of its mass. Snow hardness averaged 12000 g/sq. cm, and the mean density of the snow was 397 kg per cu m. The energy required to build and heat each iglu was calculated from the snow characteristics, construction activities and microclimate parameters measured during occupancy. Heat flux was calculated for human bodies, kudliks (seal oil lamps), and geothermal sources at temperature differentials as high as 45 C from ambient, for both the unlined large iglu and the small iglu, which was lined with caribou skins on the inside. The smaller iglu was more efficient, requiring the fat of one seal every 6.3 days for heating, while the large iglu required the fat of one seal every 3.7 days. The meat content of each seal would have sustained a family of four for the same time interval, and the resultant body heat would have provided 8% to 14% of the total energy necessary to maintain comfortable temperatures within the iglu.On a Ă©valuĂ© la valeur de la protection offerte par les igloos de neige Ă  Resolute (74° 40' de latit. N.) dans l'ExtrĂȘme-Arctique canadien. On a d'abord procĂ©dĂ© Ă  un relevĂ© de l'Ă©tat de la neige, puis choisi les sites et construit et Ă©quipĂ© deux igloos de façon traditionnelle. Soixante-douze blocs de neige pesant en moyenne 23,6 kg ont servi Ă  construire le grand igloo (4,1 m de diamĂštre) dont le rapport surface:volume Ă©tait Ă©gal Ă  2,21. Quarante-six blocs pesant en moyenne 28,2 kg ont servi Ă  la construction du petit igloo dont le rapport surface:volume Ă©tait Ă©gal Ă  1,73. Ce petit igloo reprĂ©sentait 75 p. cent de l'espace du grand igloo pour 76,5 p. cent de sa masse. La duretĂ© de la neige Ă©tait en moyenne de 12 000 g/cmÂČ et sa densitĂ© moyenne de 397 kg/mÂł. On a calculĂ© l'Ă©nergie nĂ©cessaire pour construire et chauffer chaque igloo Ă  partir des caractĂ©ristiques de la neige, des activitĂ©s relatives Ă  la construction et des paramĂštres du microclimat mesurĂ©s au cours de l'occupation. On a calculĂ© le flux thermique pour les corps, les kudliks (lampes Ă  l'huile de phoque) et les sources gĂ©othermiques Ă  des diffĂ©rences de tempĂ©rature allant jusqu'Ă  45 °C au-dessus de la tempĂ©rature ambiante, et ce, pour le grand igloo nu et pour le petit qui, lui, Ă©tait tapissĂ© de peaux de caribou sur les parois internes. Le petit igloo Ă©tait le plus Ă©conergĂ©tique, ne consommant pour le chauffage que la graisse d'un phoque tous les 6,3 jours alors que le grand igloo en consommait autant tous les 3,7 jours. La viande de chaque phoque aurait assurĂ© la subsistance d'une famille de quatre personnes au cours des mĂȘmes pĂ©riodes, et la chaleur animale qui en aurait rĂ©sultĂ© aurait fourni de 8 Ă  14 p. cent de l'Ă©nergie totale nĂ©cessaire pour maintenir une tempĂ©rature confortable dans l'igloo

    `In pursuit of the Nazi mind?' the deployment of psychoanalysis in the allied struggle against Germany

    Get PDF
    This paper discusses how psychoanalytic ideas were brought to bear in the Allied struggle against the Third Reich and explores some of the claims that were made about this endeavour. It shows how a variety of studies of Fascist psychopathology, centred on the concept of superego, were mobilized in military intelligence, post-war planning and policy recommendations for ‘denazification’. Freud's ideas were sometimes championed by particular army doctors and government planners; at other times they were combined with, or displaced by, competing, psychiatric and psychological forms of treatment and diverse studies of the Fascist ‘personality’. This is illustrated through a discussion of the treatment and interpretation of the deputy leader of the Nazi Party, Rudolf Hess, after his arrival in Britain in 1941
