In this paper, by analyzing the coal mine safety accident of present stage, the author has come to a conclusion that the safe accidents on coalface accounting for a lot of coal mine safety accident, and has brought forward the cause leading to this phenomenon. Then, through the discussion about “Overlying Strata Movement Law”, this author has suggested that Electronic Business can be used for t...

The two primary measures of land mine detection performance are the probability of detection Pd and the probability of false alarm Pfa.These two measures are highly interdependent and must be evaluated together. The relationship between the two probabilities directly a ects the overall performance of the sensor in the eld. In this paper we introduce a novel false alarm non-parametric lter based...

background : in china, over 80% of all work-related deaths in the mining industry occur in coal mines and human factors constitute 85% of the direct causes of coal mine accidents, which indicates that significant shortcomings cur-rently exist in the safety behavior management of chinese coal mine workers. we aimed to verify the impact of human psychological behavior in coal mine accidents syste...

dry matter remobilization, grain filling rate and duration has principle role on rice grain yield, and environment condition directly affect on them. for study the influence of climate factors a factorial field experiment in randomized complete blocks design with three replications conducted at haraz extention and technology development centre in spring 2013. treatments included rice cultivars ...

through an application of genetic engineering, genes from a soil bacterium bacillus thuringiensis (bt) which confer resistance to pests were transferred into rice. successful employment of genetic engineering in traditional breeding programs is dependent upon stable transmission of transgene in transgenic varieties. three different segregating f2 populations were developed from a cross between ...

A study was conducted on genetics of some important agronomic traits (number of productive tillers per hill, plant height (cm), panicle length (cm), number of spikelets per panicle and 100-grain weight) in rice during 2012-13. Two lines were crossed with five testers in line × tester fashion to produce 10 F1 hybrids. Analysis of variance revealed significant differences among genotyp...

Papaverfugax Poiret population Tarom was shown to contain one major alkaloid, mecamberine (0.4%), and six minor alkaloids, roemerine, pronuciferine, protopine, thebaine, nornuciferine and salutaridine. Nornuciferine was detected for the first time in P. fugax

Papaver pseudo-orientale population Tarom was shown to contain two major alkaloids, isothebaine (0.65%), Orientalidine (0.15%) and four minor alkaloids, bracteoline, mecambridine, Or and a novel alkaloid, nor-methyl Or .

The Schneeberg mine in the south-western part of Saxony (Germany) is flooded up to the overflow level. The mine water discharges via a historical adit to the Zwickauer Mulde river. Although the Schneeberg mine has been flooded for a 50 years period, and it is relatively small, the mine discharges a significant arsenic load at a nearly constant level, which seems to be typical for base metal/ ur...
