Co-pyrolysis of Shenmu coal (SM) and cotton stalk (CS) at different blend ratios were carried out in a tubular furnace. The pyrolysis temperature was up to 600 °C at 5 °C/min and kept for 15 min. The results indicated that there was an interactive effect between SM and CS, which increased the tar yield. Moreover, the content of light components in co-pyrolysis tar from all CS/SM blend ratios wa...

Ultra-microfluorometric techniques were adapted to follow the time sequence of glycogen degradation during the differentiation of two cell types in Dictyostelium discoideum. Glycogen content, glycogen phosphorylase activity, and inorganic phosphate accumulation were localized in specific cell types during stalk and spore development. Glycogen levels in pre-stalk cells remained constant during t...

Abstract There are plant cuticle and complex cell walls on the outer surface of cotton stalk bark (CSB), which reduce efficiency liquid penetration CSB. To increase permeability liquids, these barriers need to be broken. Cellulase can selectively hydrolyze cellulose into glucose, its action conditions mild. Therefore, cellulase treatment is one excellent ways break CSB permeation barrier. This ...

the main object of this study was to evaluate the effect of tillage and crop residues management of barley (hordeum vulgare l.) on quantification and qualification yield of corn (zea mays l.). treatments were laid out in complete randomized block design with seven treatments and three replications and include (1) fire of straw and stubble, plow, disc and furrower (2) gathering and transfer of s...

The variation of highly pathogenic avian influenza H5N1 virus results in gradually increased virulence in poultry, and human cases continue to accumulate. The neuraminidase (NA) stalk region of influenza virus varies considerably and may associate with its virulence. The NA stalk region of all N1 subtype influenza A viruses can be divided into six different stalk-motifs, H5N1/2004-like (NA-wt),...

Rotation of the coiled-coil stalk of the kinesin-14 motors is thought to drive displacements or steps by the motor along microtubules, but the structural changes that trigger stalk rotation and the nucleotide state in which it occurs are not certain. Here we report a kinesin-14 neck mutant that releases ADP more slowly than wild type and shows weaker microtubule affinity, consistent with defect...

Structures erected on swelling clay soils are subjected to several stresses which at the origin of premature deterioration infrastructures. The being supports for works, improvement their weak characteristics with cotton fibers will not only increase bearing capacities these and resolution environmental problem, by eliminating CO2 produced burning stems after harvest. objective this study is co...
