kermanshah province is the main producer of various chickpea cultivars in iran. in this study a laboratory peg-tooth thresher was employed for chickpea threshing. the effect of cylinder speed (9, 12, 15 m/s), concave clearance (12, 14, 16 mm), feed rate (80, 160, 240 kg/h) and material moisture content (5, 10, 15% w.b.) was studied on percentage of grain damage, threshing efficiency and percent...
As the main harvesting machinery, combine harvester is often due to improper adjustment of its operating parameters resulting in increased crushing rate and grain waste during process. To quickly obtain working range key under low rate, this study conducted field tests on relevant affecting finally selected travel speed, feed threshing drum concave clearance, as node variables for construction ...
Drum shell bearing edges dictate the boundary conditions and point of contact between drum heads and drum shells. Properties of single 45o, single 45o with slight round-over, and double 45o bearing edges have been studied. It has been found that the double 45o drum allows for the best head/shell energy transfer. I. Background Tom drums are typically composed of a wooden drum shell, a head that ...
Wheat domestication from wild species involved mutations in the Q gene. The q allele (wild wheats) is associated with elongated spikes and hulled grains, whereas the mutant Q allele (domesticated wheats) confers subcompact spikes and free-threshing grains. Previous studies showed that Q encodes an AP2-like transcription factor, but the causal polymorphism of the domestication traits remained un...
We present a live drum separation system for a specific target drumset to be used as a front end in a complete live drum understanding system. Our system decomposes drum note onsets onto spectral drum templates by adapting techniques from non-negative matrix factorization. Multiple templates per drum are computed using a new Gamma mixture model clustering procedure to account for the variety of...
We report on the discovery of a new potential galaxy threshing system in the COSMOS 2 square degree field using the prime-focus camera, Suprime-Cam, on the 8.2 m Subaru Telescope. This system consists of a giant elliptical galaxy withMV 21:6 and a tidally disrupted satellite galaxy withMV 17:7 at a photometric redshift of z 0:08. This redshift is consistent with the spectroscopic redshift of 0....
INTRODUCTION Agricultural producers are exposed to a number of different health risks associated with their work environment. AIM The objective of the study was to assess the degree of colonization by fungi in terms of quantity and in terms of variety of species the samples taken from the settled dust from combine threshing of rye cultivation from organic and conventional farms in the Provinc...
