Zooarchaeologists have long recognized that the use of different sizes of screen in excavation can result in varying degrees of bias in faunal samples. This paper presents a graphical, mathematical representation of the ways in which screen size choice can affect measures of taxonomic relative abundance. Data from the site of Mogollon Village in southwestern New Mexico show that the rank order ...

The above core services will provide the basis of an electronic business system that will be available throughout Australia. As the system is developed, further services will be provided to ensure that Transigo remains current with the latest drvelopments in technology and business practice. A limited version of the scheme is alrcady in operation, and a public launch has been scheduled for earl...

Development of village chicken production can be a sustainable way of helping to meet the welfare needs of rural populations and raise their living standards. There is a dearth of information on research conducted to characterize, understand and develop the village chicken production systems in Zimbabwe. This review focuses on constraints, opportunities and research needs for the improvement of...

BACKGROUND This study evaluates the extent of village doctors' knowledge of lead poisoning in children in rural China and assesses the characteristics associated with possessing accurate knowledge. METHODS A cross-sectional, questionnaire-based survey of 297 village doctors in Fenghuang County, Hunan Province, China was conducted. All village doctors were interviewed face-to-face using a "Wha...

Interleukin-8 (IL-8) and the structurally related cytokines neutrophil-activating peptide-2 (NAP-2) and GRO alpha are powerful chemotactic agents for human neutrophils. Although these three chemokines act by binding to overlapping but not identical receptor subsets, the data available to date have stressed the similarities in their mechanisms of action. The present studies were undertaken to fu...

This paper proposes a high frequency ring oscillator with low power consumption. The proposed ring oscillator is based on Gated Ring Oscillator (GRO) by applying boot strap technique. Simulation results indicate that the FoM (Power Consumption /Oscillation Frequency) of the proposed ring oscillator is greater than that of the conventional ring oscillator. Figure 1 shows delay element using boot...

The sterile insect technique (SIT) is widely used in integrated programs against tephritid fruit fly pests, particularly the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). Unfortunately, the mass-rearing procedures inherent to the SIT often lead to a reduction in the mating ability of the released males. One potential solution involves the prerelease exposure of...

A transient X-ray source, GRO J1008[57, was discovered by the Burst and Transient Source Experiment (BATSE) on board the Compton Gamma Ray Observatory (CGRO) in 1993 July. It reached a maximum intensity of about 1.4 times that of the Crab, in the 20È60 keV energy band. Pulsations in the X-ray intensity were detected at a period of 93.5 s. It has subsequently been determined to be a member of th...
