Exploratory drilling on the Seychelles Bank, in a sector west of outcrop granite on Mahé Island, has revealed the presence of substantial Mesozoic colums. Their thicness approaches 3,000m; and total Phanerozoic down to true basement probably exceeds 4,500m. Still greater depths are possible, not only in this drilled NW-most sector of the island arc of the Mascarene Ridge, but also elsewhere along the arc, whose total cross-latitudinal dimension is more than 2,000km. Volcanics, like those in the African borderlands, repeatedly enter the Phanerozoic column of the Seychelles. The young "basaltic basement" of geodynamic theory, consequently, cannot exist on the Seychelles Bank. The same negative may hold true for the whole arc of the Mascarene Ridge and for its marginal waters westward as far back as the African borderlands themsleves. In the domain of exploration, the prime parameter of sedimentary volume is acceptable along much of the Mascarene Ridge, for which reason wells drilled to true basement merit consideration in future drilling. Such wells in central and southern sectors might recover basement rocks whose petrology could offer a strong challenge to present concepts of paleogeography in the whole back-arc area of the western Indain Ocean. 相似文献

Infarcts in the territory of the anterior spinal artery usually are located in the Adamkiewicz artery. Onset is either sudden or progressive with clinical signs of deficit and spinal pain of short duration. The extent and distribution of the deficit depends on the extension and the level of the spinal lesions. A perfect knowledge of the spinal cord vascularization is required to discern the complex and variable clinical expression. Unlike cerebral vascular events, emboli or cardiac origin are rarely involved in spinal cord events. Aortic pathology, including surgery of the aorta, is however of major importance in ischaemic spinal cord syndromes. Several reports have shown that atheroma causing spinal cord ischaemia are not located in the perispinal arterial network but lie on the aorta and its spinal branches. Dissection of the aorta is found responsible in 2 to 8% of the cases. Isthma stenosis can also give spinal cord signs and syphylitic arteritis is exceptionally encountered. Other rare causes are gas emboli and fibrocalcium emboli. 相似文献

Four studies examined aspects of the differential emotions theory (DET) hypothesis of expressive behavior development. In Study 1, facial-expressive movements of 108 2.5–9-mo-old infants were video recorded in positive and negative mother–infant interactions (conditions). As expected, Max-specified full-face and partial expressions of interest, joy, sadness, and anger were morphologically stable between the 2 ages. Studies 1 and 2 confirmed predicted differential responding to mother sadness and anger expressions and to composite positive and negative conditions. Discrete negative expressions exceeded negative blends, and the amount of both expression types remained stable across ages. Studies 3 and 4 provided varying degrees of support for the social validity of Max-specified infant negative affect expressions. Conclusions include revisions and clarifications of DET.

Meta-accuracy, knowing how others view the self, was examined using the Social Relations Model. 15 groups of 4–6 acquainted individuals gave self-ratings, perceptions of other group members, and estimated others' perceptions of self (metaperceptions) on the Big Five and Interesting. Individuals also rated liking and metaperceptions of liking. Trait perceptions were consensual, and self–other agreement emerged for most traits. Affect judgments were entirely relational; individuals differentiated among targets. Trait metaperceptions were dominated by perceiver variance. Individuals differed in the impression they believed others generally held about them. Affect metaperceptions, however, were relational in nature. Correlations between perceptions and metaperceptions assessed 2 types of meta-accuracy. Generalized meta-accuracy was obtained for some trait ratings. Affect judgments revealed significant dyadic meta-accuracy. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

A set of 11 expression vectors was constructed, each of themharbouring a cloning cassette under the control of the promoter.Some of these vectors enable expression of foreign proteinsin the cytoplasm, while others include a synthetic sequencecoding for a very efficient secretion signal sequence. Otherfeatures are an fl origin of replication (in plus or minus orientation)and a promoterup mutation that enhances the already very highlevel of expression from these vectors. With such a versatilevector family, cloning, sequencing and sitedirected mutagenesiscan be performed on the same vector, and the level of expressioncan be defined according to the specific constraints of a givenprotein. 相似文献

Reviews the book, From models to modules: Studies in cognitive science from the McGill workshops edited by I. Gopnik and M. Gopnik (1986). This book is only moderately successful in conveying the exciting advances that are beginning to appear as a result of the interdisciplinary efforts in cognitive science. The book's emphasis on language processes and linguistics will seriously limit its potential readership, although there are some contributions from outside that domain. Moreover, many of the chapters were not prepared with a general audience in mind, and to appreciate a number of the chapters fully the reader must have a strong linguistic background. A more severe problem is that the chapters are based on a series of workshops held at McGill University in 1982 and 1983. The sad consequences are that (a) the book is badly out of date (few references are more recent than 1983), (b) most of the contributions were not original but were based on ideas and results that were or were about to be in print at the time the workshops were held, and (c) many of the chapters are so short that they do not provide adequate depth of coverage. At this late date, the value of the book may be as a summary of a few of the early issues and methodologies that have captured the attention of cognitive scientists.

Performance on computer-simulated, everyday memory tasks was found to deteriorate with age in 434 Belgian (aged 14–88 yrs) and 434 American Ss matched on gender and age. This age-related memory decline was reasonably consistent across samples. Difficulties in cross-cultural research and the advantages of ecologically valid measurement instruments are discussed. Instruments included a grocery list selective reminding test, the Wechsler Memory Scale, the Benton Visual Retention Test, and the Wechsler Adult Intelligence Scale (WAIS).

A practical work on design of analog bipolar integrated circuits is presented. The designed circuits are fabricated by Thomson composants militaires et spatiaux(TCMS,) and subsequently measured by the students. The semi-custom technique of pre-diffused array allows no prerequisite knowledge on technology. The process used(HF2C) has a large field of applications due to high performance of the available components (ft = 3 GHz for theNPN transitors). TheCAD tools involved areSPICE for circuit simulation and Princess (Silvar Lisco) as the layout editor. After being experimented atENSERG, this possibility is extended to a national level within the frame of the French multi chip project (CMP). 相似文献

This paper reports on statistics concerning production and consumption of packaging (as a whole or per capita) in Europe, in the USA, in Japan and in the world. Data have been provided by National Trade Associations and by consultants specialized in packaging and in economics. It is estimated that in 1986 the global consumption of packaging reached 150 millions of tonnes valued at 1200 billions of French francs. Consumption could reach 247 million tonnes by the year 2000. Paper and board have the highest consumption rate, but plastics have the highest rate of growth. Nevertheless, consumption per capita in the industrialized countries will be more than 10 times the consumption in underdeveloped countries. The packaging industries take fourth place in the USA, sixth in Western Germany and twelfth in France. In Europe, as in the world, paper and board is the material most used (40%), with glass (a high density material) taking second place and plastics third, i.e. if we consider the quantity of materials and not their value. Some differences appear between the various countries, but the figures for USA and Japan lead to similar conclusions. The survey shows clearly that the USA as compared with Europe has twice the consumption of packaging materials per capita and this difference is even greater compared with the rest of the world. 相似文献

We propose a sensor based on the temperature dependant behavior of the two lines of green emission of the erbium ion. The ratio of the intensities of these two lines presents a very low dependance on pump wavelength and pump power fluctuations. The sensitivity of the ratio is 0.013/°C between room temperature and 600°C. In addition, the measurement is self-calibrated 相似文献
