Late Pleistocene/Holocene wetland events recorded in southeast Tengger Desert lake sediments,NW china

chinese Science Bulletin 2003年第14期48卷 1423-1429页

作者： D.B.Madsen chENFahu ch.G.Oviatt ZHUYan P.j.Brantinaham R.GoElston R.L.Bettinger TexasArcheologicalResearchLaboratory UniversityofTexasAustinTX78712USA CAEENationalLaboratoryofWesternchina'sEnvironmentalSystem LanzhouUniversityLanzhou730000China DepartmentofGeoi0gy KansasStateUniversityKansasUSA DepartmentofAnthropology UniversityofCaliforniaLosAngelsUSA SilverCity Nevada.USA DepartmentofAnthropology UniversityofCaliforniaDavisCA95616USA

The area along the eastern and southeastern margins of the Tengger Desert, NW china, which is sensitive to the summer monsoon variations, was selectedfor studying the environmental conditions surrounding the transition between Paleolithic foragers and Neolithic farmer/pastoral- ists. Short cores were obtained from four lake basins in the southwestern Tengger using a hand-driven piston coring device. Proxies from these cores were supplemented by ra- diocarbon ages obtained from lake sediment cores, shoreline features and spring mound deposits. Together these records provide evidence of millennial-scale climate change events from the Pleistocene-Holocene transition to the present. Lake/wetland events, representing periods of more intensive summer monsoon, occur in the records at ～12.7-11.6, ～10.1, ～9.3, ～8.0, ～5.4, ～1.5, and ～0.8 ka BP. They do suggest that century- to millennial-scale climatic cycles are characteristic of the Holocene in the southeastern Tengger Desert although the chronology must be considered extremely tentative.

Emerging Food-borne Pathogens

引用

Biomedical and Environmental Sciences 2001年第1期14卷 44-52页

作者： jRGEN SchLUNDT Programme of Food Safety

The epidemiology of foodborne diseases is changing. While in many developing nations the efficient treatment of diarrhoeal diseases through oral rehydration has probably led to the prevention of many food related deaths, the underlying problems have not been solved. In these countries, the disease incidence of food_and waterborne disease is still increasing, and now data from other parts of the world indicate that new foodborne pathogens have emerged as important public health problems. Over the last two decades, bacterial infections caused by Campylobacter and enterohaemorrhagic Escherichia coli have emerged, well_recognized pathogens, such as Salmonella enteritidis, have increased dramatically in disease incidence and important foodborne pathogens have become increasingly resistant to antimicrobial agents. The future strategy for prevention of foodborne disease should be founded in scientifically based evaluations of the whole food production chain ‘from farm to table’, including a description of the most important (risk) factors. Epidemiological studies of outbreaks as well as sporadic cases should be aimed at a better understanding of these factors. In terms of public health importance of the problem, the focus should be on the size of the problem, and the potential for improvement. The indications are that both in developed and developing countries there is significant potential for an improvement of the situation. With this aim in mind, international effort should focus on scientific assessments of the potential for risk reduction under different regional conditions.

作者： Tilemachos j. Kalvouridis Maria ch. Gousidou-Koutita Department of Mathematics Faculty of Sciences Aristotle University of Thessaloniki Thessaloniki Greece Department of Mechanics Faculty of Applied Sciences National Technical University of Athens Athens Greece

We deal with the Copenhagen problem where the two big bodies of equal masses are also magnetic dipoles and we study some aspects of the dynamics of a charged particle which moves in the electromagnetic field produced by the primaries. We investigate the equilibrium positions of the particle and their parametric variations, as well as the basins of attraction for various numerical methods and various values of the parameter λ.

The aim of this work was to develop a Ti6Al4V/20CoCrMo−highly porous Ti6Al4V bilayer for biomedical *** powder metallurgy technique,with semi-solid state sintering as consolidation step,was employed to fabricate samples with a compact top layer and a porous bottom layer to better mimic natural *** densification behavior of the bilayer specimen was studied by dilatometry and the resulting microstructure was observed by scan electron microscopy(SEM)and computed microtomography(CMT),while the mechanical properties and corrosion resistance were evaluated by compression and potentiodynamic tests,*** results indicate that bilayer samples without cracks were obtained at the interface which has no negative impact on the *** values of the highly porous layer were in the lower range of those of human *** compression behavior is dictated by the highly porous Ti6Al4V ***,the corrosion resistance of Ti6Al4V/20CoCrMo is better than that of Ti6Al4V,which improves the performance of the bilayer *** work provides an insight into the important aspects of a bilayer fabrication by powder metallurgy and properties of Ti6Al4V/20CoCrMo−highly porous Ti6Al4V structure,which can potentially benefit the production of customized implants with improved wear performance and increased in vivo lifetime.
