hydroponic experiments were performed to exam the dynamic change of endogenous proline in rice seedlings exposed to potassium chromate chromium (vi) or chromium nitrate chromium (iii). although accumulation of both chromium species in rice seedlings was obvious, more chromium was detected in plant tissues of rice seedlings exposed to chromium (iii) than those in chromium (vi), majority being in...

The soil heavy metal pollution around the mine threatens crop growth and human health. Intensively studies of distribution characteristics source metals some typical mines are very crucial for environmental management green development mine. A total eighty-nine samples, twenty-one sediment five waste rock samples two tailing sand were sampled to investigate copper (Cu), lead (Pb), zinc (Zn), ar...

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...

Learning a new language involves significant vocabulary acquisition. Learners can accelerate this process by relying on words with native-language overlap, such as cognates. For bilingual third language learners, it is necessary to determine how their two existing languages interact during novel language learning. A scaffolding account predicts transfer from either language for individual words...
