In order to solve the problem of high broken rate and impurity in direct harvesting corn kernels China, a flexible threshing element with variable stiffness consisting conical spring rasp bar was developed on basis existing horizontal axial-flow flow cylinder structure achieve low loss kernels. Through mechanical analysis key components element, its operating parameters were determined. Then, o...

The aim of this paper is a comparison of the operating parameters of combine harvesters on a selected farm. The working parameters were measured and evaluated on combine harvesters of the CLAAS and CASE IH brand by different ages and different concepts of threshing. Measuring took place in the season of 2013 and 2014 (Lexion 770 in 2012 too). Working parameters in this case mean the performance...

After years of use, there’s oil loss on the asphalt pavement. bond strength aggregate decreases. Loose threshing is serious. In order to improve pavement performance, Extend service life pavement, Improve safety aircraft operation. We test AC-20 modified mixture taxiway and runway Chang Sha Airport from many factors, including raw materials, admixtures, gradation design, optimum ratio stone, th...

Functional glycomics has been impeded by the lack of inexpensive enzymatic and mild chemical methods to acquire natural glycans in significant amounts. In this study, we have developed a new strategy we term "threshing and trimming" (TaT) to quickly obtain N-glycans from glycoproteins and animal tissues. TaT employs low-cost Pronase to degrade peptides and N-bromosuccinimide (NBS) to effect oxi...
