The normal levels of arsenic in human tissue are reported together with the arsenic concentrations found in the investigation
of a large number of industrial exposure incidents. These results are useful for establishing that industrial exposure has
taken place and for confirming arsenic poisoning but they cannot be used realistically to predict that any person or group
will suffer a visible deterioration in health because no correlation between arsenic contamination and symptoms can be made.
Industrial workers who are affected by arsenic exposure are often no more exposed than their co-workers. 相似文献

Direct determinations of the rate constants (cm3/molec · sec) k1, k2, and k3 from 298 to 299°K are reported, using atomic resonance fluorescence in discharge flow systems: 1 One standard deviation. The rate constant k1, which has not been determined previously, was found to possess an insignificant temperature coefficient (EA = (0 ± 700) J/mole) in the range of 299 to 619°K. The present result for k2 agrees well with reinterpreted values from the one previous determination. Measurements of O atom consumption rates and Br atom production rates in the O + Br2 reaction are interpreted to give an estimate of the rate constant k4, which has not been reported previously, at 298°K: k3 has been measured at three temperatures between 299 and 602°K. The present and previous results for k3 were combined to give the following rate expression: 相似文献

This paper describes further development and experimental testing of the INAA Advance Prediction Computer Program (APCP).
Copies of the APCP written in BASIC-PLUS are finally ready for distribution. Experimental tests with four reference materials
are described. The program is extremely useful as a quide to optimum conditions, sample sizes, elements detectable, and INAA
lower limits, of detection for any sample matrix of only approximately known major and minor elemental composition. Additional
developments in progress are mentioned. 相似文献

Single crystals of a pure hydrocarbon, 1,3,5-triphenylbenzene, with properties suitable for high-energy neutron detection were grown from toluene solutions using slow evaporation and temperature reduction methods with growth rates up to 10 mm/day. Application of the rapid growth technique developed earlier for growth of large water-soluble crystals shows that crystals of aromatic compounds can be successfully grown from solutions in large volumes required for their use as scintillator materials for radiation detection. 相似文献

Background
Glutamate has been proposed as a transmitter in the peripheral taste system in addition to its well-documented role as an umami taste stimulus. Evidence for a role as a transmitter includes the presence of ionotropic glutamate receptors in nerve fibers and taste cells, as well as the expression of the glutamate transporter GLAST in Type I taste cells. However, the source and targets of glutamate in lingual tissue are unclear. In the present study, we used molecular, physiological and immunohistochemical methods to investigate the origin of glutamate as well as the targeted receptors in taste buds. 相似文献148.

In this paper, we generalize the no-neck result of Qing and Tian (in Commun Pure Appl Math 50:295–310, 1997) to show that there is no neck during blowing up for the n-harmonic flow as \(t\rightarrow \infty \). As an application of the no-neck result, we settle a conjecture of Hungerbühler (in Ann Scuola Norm Sup Pisa Cl Sci 4:593–631, 1997) by constructing an example to show that the n-harmonic map flow on an n-dimensional Riemannian manifold blows up in finite time for \(n\ge 3\). 相似文献
