    Towards improved ground models for slope instability evaluations through better characterization of sediment-hosted gas-hydrates (2002)
    Oxford, UK : Blackwell Science Ltd
    Terra nova 14 (2002), S. 0 
    Details
    ISSN: 1365-3121
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geosciences
    Notes: Recently developed effective stress-controlled geophysical property models are used in passive-margin slope instability analyses including simulated earthquake motion. The pressure–temperature (P–T) history of sediment-hosted gas hydrate may significantly alter the geophysical property profile of the sediment column (e.g. metastable cement or increased pore pressures). This can result in significant amplification of earthquake ground motion, and thus seabed instability, where hydrates are present. Published studies suggest destabilization of these high-pressure/low-temperature sediment-hosted hydrates could trigger catastrophic slope failures with consequent liberation of ‘greenhouse’ gases and significant effects on global climate. To provide improved ground models for slope instability analyses we are investigating the influence of P–T history on hydrate distribution in sediments through the development of laboratory techniques to enable geophysical quantification of hydrate morphology and fabric on hydrate stability.

    Notes: [Auszug] FLYING swarms of locusts often cannot be effectively attacked from the air because of the danger to the aircraft. Attention is therefore focused on the circumstances in which a swarm will remain on the ground. In Kenya the desert locust, Schistocerca gregaria (Forsk.), roosts overnight in trees ...

    Notes: [Auszug] WHEN writing the book referred to by Dr. Kennedy, we were frequently faced with the alternatives of inventing new technical terms (which are often resented by the people who have to learn and use them) and of using common words in newly defined ways (which causes trouble because it is difficult ...

    Notes: [Auszug] A search of published information and local records regarding two outbreak regions of the red locust, the Mweru wa Ntipa in Northern Rhodesia and the Rukwa Valley in Tanganyika, suggested that wet periods of years were always unfavourable to locust numbers and dry periods were sometimes ...

    Notes: [Auszug] THE most commonly effective method of destroying locusts at present is to poison the hoppers (nymphs) before they can fly. Some kind of bait, such as moistened bran, which is eaten in preference to other food, is poisoned with benzene hexachloride (hexachlorocyclohexane, 'Gammexane', 'Benhex') and ...

    The temperature and humidity relations of the cockroach (Blatta orientalis) (1934)
    Springer
    Journal of comparative physiology 20 (1934), S. 617-625 
    Details
    ISSN: 1432-1351
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary 1. An apparatus is described in which a steady temperature gradient can be maintained and in which conditions of temperature and humidity can be accurately measured. 2. The preferred temperature range (indifference zone) of normal adult male Blatta orientalis in this apparatus is 20–29 ° C. 3. The indifference zone is not altered by changes in the humidity of the air. 4. Specimens desiccated to 70% of their original weight show a much lower preferred temperature, namely 12–23 ° C. 5. This is interpreted as a reaction to a gradient of saturation deficiency, an avoiding reaction against air of higher evaporating power.

    Notes: [Auszug] MR. YAPP'S communication on this subject1 is of considerable interest because it suggests that temperature may be a more suitable stimulus than pH for making a quantitative investigation of klino-kinesis in Paramecium. A quantitative study is required to discover how completely ...
