Lead pollution incidents have occurred frequently in mainland China, which has caused many lead poisoning incidents. This paper took a battery recycling factory as the subject, and focused on measuring the blood lead levels of environmental samples and all the children living around the factory, and analyzed the relationship between them. We collected blood samples from the surrounding resident...

In many knowledge-based systems the used knowledge is distributed among several knowledge sources. These knowledge sources may have dependencies between each other, which should be considered when maintaining these sources. An integrated maintenance approach for multiple Case-Based Reasoning (CBR) systems has to consider dependencies between the individual knowledge containers within one CBR sy...

Samples of blood, air, dust, soil, vegetation, and tap water were examined between 1973 and 1975 to determine whether a large battery factory (with a smelter) was contributing to lead in the environment and to lead absorption by the local population. Mean blood lead levels in the children of lead workers were about 6 pg/100 ml higher (P <0.001) than in otherwise comparable children. Capillary b...

In the last years an enormous progress has been made in improving the visual quality of virtual worlds through approximations of former computationally expensive global illumination (GI) effects. Nevertheless, the handling of dynamic or even deformable content in massive data sets illuminated and shadowed by massive light sources still represents some kind of killer application. Besides the gam...

The use of different organic carbon sources in the denitrification of wastewater containing 2500 mg nitrates/L in a SBR was studied. Three alternative sources of carbon were tested: wastewater from a sweet factory, a residue from a soft drinks factory and a residue from a dairy plant. The first two are sugar-rich, whereas the third presents a high content in lactic acid. Maximum specific denitr...

In this study, the hypothesis that mammalian ventricular myocytes possess A2-adenosine receptors was tested. Electrophysiological, contractile, and cAMP responses to the selective A2-adenosine receptor agonists 2-[2-(4-methylphenyl)ethoxyladenosine (WRC-0090) and 2-(2-cyclohexylethoxy)adenosine (WRC-0013) and the nonselective adenosine receptor agonist 5'-(N-ethylcarboxamido)adenosine (NECA) we...

the purpose of this research was to investigate the attitude of vegetable growers towards sources of soil pollution in ray county. the study consisted of all vegetable growers (n=700) in ray county, located in tehran province, from which 70 vegetable growers were selected through random sampling technique. a planned questionnaire was used as the main instrument to collect data. the content vali...

We have measured the branching ratio BR(φ → ππγ) with the KLOE detector using a sample of ∼5 × 10 φ decays. φ mesons are produced at DAΦNE, the Frascati φ-factory. We find BR(φ→ππγ)= (1.09 ± 0.03stat ± 0.05syst)× 10 . We fit the two–pion mass spectrum to models to disentangle contributions from various sources.
