Smart, M. G., Shotwell, O. L., and Caldwell, R. W. 1990. Pathogenesis in aspergillus ear rot of maize: Aflatoxin B1 levels in grains around woundinoculation sites. Phytopathology 80: 1283-1286. Aflatoxin contamination of preharvest maize intermittently presents serious problems in grain storage and in animal health. To determine whether this mycotoxin can be translocated through the ear in the ...

Image inpainting automatically restores damaged images and partially removed pictures. Since most inpainting mechanisms inpaint damaged portions in a single layer, this study proposes a multilayer inpainting mechanism by examining how Chinese paintings are drawn in layers. The proposed multilayer inpainting mechanism employs a layer fusion strategy to detect the optimal inpaint combination amon...

Field study was conducted to evaluate the effectiveness of formulated baits of 0.005% brodifacoum, 0.0375% coumatetralyl, 0.005% bromethalin and 2% zinc phosphide against field rats inhabiting sugarcane crop. The efficacy was calculated on the criterion of reduction in rodent activity, damaged canes and yield of harvested canes. After five applications of baits, the rodent activity reduced to 9...

From 1995 to 1998, more than 90 percent of mid-range IPOs were charged underwriter fees, or spreads, of exactly seven percent, even though evidence suggests that economies of scale in the size of the offering should allow for lower fees. Chen and Ritter (2000) offer collusion as a possible explanation based on empirical analysis and observation. Alternatively, we investigate whether the spreads...

In order to evaluate the efficiency of biocontrol agents of corn stem borer ,Ostrinia nubilalis, experiment was conducted in a randomized complete block by five treatments and four replication, including, Indoxacarb (Avant)®, Trichogrammawasps, Bacillus thuringiensis var: kurstaki, integration of Trichogramma sp. and Bt., and cont...

Though cytoplasmic male sterility (CMS) in peppers is associated with the orf507 gene, definitive and direct evidence that it directly causes male sterility is still lacking. In this study, differences in histochemical localization of anther cytochrome c oxidase between the pepper CMS line and maintainer line were observed mainly in the tapetal cells and tapetal membrane. Inducible and specific...

The following factors must be considered when dye exclu sion assays are interpreted, (a) It may require several days for lethally damaged cells to lose their membrane integrity follow ing a cytotoxic insult, (b) During this time, the "surviving" cells may continue to proliferate, (c) Also during this time, some lethally damaged cells may undergo an early disintegration, so that they are not pre...

The sputtering of the lunar surface by the solar wind is examined as a possible mechanism of mass fractionation. Simple arguments based on current theories of sputtering and the ballistics of the sputtered atoms suggest that most ejected atoms will have sufficiently high energy to escape lunar gravity. However, the fraction of atoms which falls back to the surface is enriched in the heavier ato...
