The HN 1–117 stalk N-glycosylation mutants were expressed in cells and were metabolically labeled, and the proteins were immunoprecipitated using HN pAb R471 (Fig. 3B). The decrease in electrophoretic mobility of these mutants compared with HN 1–117 stalk on a SDS/PAGE gel indicates that these mutants are glycosylated. The minor …

The accurate evaluation of the stalk-lodging resistance during the late stage of maize growth can provide a basis for the selection of cultivars, the evaluation of cultivation techniques, and timely mechanical grain harvesting. In this study, the critical wind speed of stalk breaking, plant morphology, stalk mechanical strength, and lodging rate …

The Reichert spiral which has been particularly developed for the beneficiation of fine coal in the size range of −3 + 0.1 mm is considered as an alternative for fine coal jig, cyclone, and flotation. A systematic study has been carried out to test the separation efficiency of the Reichert spiral on a bituminous coal and lignite.

The Reichert cone is a wet gravity concentrating device that was designed for high-capacity applications in the early 1960s, primarily to treat titanium-bearing beach sands (Ferree, 1993).Its principle of operation is similar to the pinched sluice. Figure 10.31 shows a schematic of a Reichert cone, with the feed pulp being distributed evenly around the …

The endosomal sorting complex required for transport (ESCRT) mediates cellular processes that are related to membrane remodeling, such as multivesicular body (MVB) formation, viral budding and cytokinesis. Abscission is the final stage of cytokinesis that results in the physical separation of the newly formed two daughter cells. Although abscission has …

Spiral concentrators (Fig. 5.2.3) are devices to separate different solid components in slurrybased upon a combination of the solid particle density, as well as the particle's hydrodynamic properties (e.g., drag).The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid …

The first step is to peel the burdock flower stalk, and I used my pocket knife to peel off the stringy exterior. The remaining stalk was still rigid and a bit stringy, but it went right into the pot. A quick boil, and I'll be honest, I was unimpressed. The exterior of the stalk is still bitter and really tough.

Dense planting effectively increases maize yield while increasing stalk lodging risk. Appropriate row spacing can improve the maize population structure and stalk lodging resistance, but its physiological ecological mechanisms and interaction with planting density are unclear. Here, a two-year field experiment to determine the joint effects of row …
