explants of leaves, petals, anthers, styles and ovaries of c. speciosus, c. cancellatus, c. gilanicus and c. almehensis were cultured on ls media with three different combinations of naa and bap in the dark. callus and neoformant organs (leaf and corm-like structure and ordinary and contractileroots) were fomd on some of these explants. corm explants from these species were also cultured on ms ...

The first stage in the preparation of rice for food is the threshing of the harvested crop to yield paddy rice. This consists of the rice berry (or grain) enclosed in a rough, fibrous and silicious husk. Further preparation consists of hulling to remove this husk, followed by milling which removes the outer bran layer of the berry. For some time before beriberi was shown to result from a defici...

The work is devoted to the problem of calculating surface roughness during magnetic abrasive processing. Cutting grains have random dimensional characteristics, are randomly located on tool, workpiece has an irregular profile. cutting parts partially remove chips and elastoplastically deform metal. Some vertices fall into marks formed by previous processing, some - from passage vertices. This p...

BACKGROUND Alkylresorcinols (ARs), phenolic lipids exclusively present in the outer parts of wheat and rye grains, have been proposed as specific dietary biomarkers of whole-grain wheat and rye intake. OBJECTIVE The objective was to validate plasma ARs as a biomarker of whole-grain wheat and rye intakes by studying the correlation between their plasma concentration and intake calculated from ...

Tectonic structures controlling mineralization in some parts of Southeast Nigeria were evaluated using airborne potential field data. High- and low-frequency filters depth determination tools adopted to evaluate short- long-wavelength anomalies, resolve the spatial spreading igneous intrusions, depths geologic sources basin topography. The high-frequency results exhibited high concentration sho...

In this chapter, the analytical embedded atom method and calculating Gibbs free energy method are introduced briefly. Combining these methods with molecular dynamic and Monte Carlo techniques, thermodynamics of nano-silver and alloy particles have been studied systematically. For silver nanoparticles, calculations for melting temperature, molar heat of fusion, molar entropy of fusion, and tempe...

Plastic film mulching (PM) is widely utilized for maize production in China. However, the effect of PM on the grain yield of crops has not been established, and the biochemical mechanism underlying the increase or decrease in grain yield under PM is not yet understood. Grain filling markedly affects the grain yield. The objective of this study was to investigate the effects of PM on maize grain...
