While sexy, the theory may have a fatal flaw, says Rolf Hoekstra, an evolutionary geneticist at Wageningen Agricultural University in the Netherlands: The stalk-size genes and the suppression genes could wind up on different chromosomes during the normal process of recombination, in which the X and Y chromosomes exchange DNA.
An experimental design was established to study the effect of the stalk particle size and the epoxy/corn stalk particle ratio on the thermal and mechanical properties of the composites prepared.
Retrospectively, each patients' colonoscopy report was reviewed for polyp characteristics (sessile, semi-sessile, on a stalk), polyp size, method of polypectomy (cautery snare, hot or cold forceps), and number of polyps removed was recorded.
Stalks the size of a finger are a good measure.
These results will be helpful for designing cutting elements of corn stalk harvesting, biomass size reduction and other processing machinery.
Sink size (stalk density) responded more to a decrease in RS than source size (intercepted radiation) and the latter became insufficient to fill the sink to capacity when row spacing was less than 1.37 m.
The latter is particularly evident in group 4 where large stalk and sori size is correlated with a tendency to form solitary and unbranched fruiting bodies.
Other perennials increase in bunch size and stalk density each year.
In 1984, Raper set up a comprehensive taxonomic system that classified all species based on morphological differences such as the presence or absence of polar spore granules, sorus color, stalk features, and overall size [ 13].
The physical chemical properties of corn stalk powders with particle sizes of >300, 300-150, 150-74, 74-37 and <15 μm were investigated.
