The accumulation of heavy metals in agricultural soils is a serious environmental problem. The Campania region in southern Italy has higher levels of cancer risk, presumably due to the accumulation of geogenic and anthropogenic soil pollutants, some of which have been incorporated into organic matter. The aim of this study was to introduce and test an innovative, field-applicable methodology to...

Abstract—Flash flood is occurred in short time rainfall interval: from 1 hour to 12 hours in small and medium basins. Flash floods typically have two characteristics: large water flow and big flow velocity. Flash flood is occurred at hill valley site (strip of lowland of terrain) in a catchment with large enough distribution area, steep basin slope, and heavy rainfall. The risk of flash floods ...

OBJECTIVES To compare in persons aged 70 years or older the clinical and inflammatory changes occurring around implants and natural teeth during and after a phase of undisturbed plaque accumulation. MATERIAL AND METHODS Twenty partially edentulous participants with titanium implants refrained from oral hygiene practices while being clinically monitored in weekly intervals for 21 days. Teeth a...

This paper presents an architecture to evaluate the reliability of a systemon-chip (SoC) during its runtime that also accounts for the system’s redundancy. We propose to integrate an autonomic layer into the SoC to detect the chip’s current condition and instruct appropriate countermeasures. In the autonomic layer, error counters are used to count the number of errors within a fixed time interv...

The "middle-class neighborhood" is a breeding design intended to allow new mutations to accumulate by lessening the effects of purifying selection through the elimination of among-line fitness variation. We show that this design effectively applies soft selection to the experimental population, potentially causing biased estimates of mutational effects if social effects contribute to fitness.

ternative, however, requires a clear analysis of the origins of the crisis and a consistent set of principles for its resolution. Our aim here is to question two elements of traditional Marxist theory that we believe impede the development of such an analysis. One is the notion that the logic of accumulation is set by the character of capitalist social relations alone, the role of the state bei...
