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...

sixteen multiparous lactating buffaloes after 8 weeks of calving and weighing 500 to 600 kg were used in a complete switch-back design with four groups. buffaloes in the first group were fed the control ration (r1) consisted of dm basis of 60% concentrate feed mixture (cfm)+20% rice straw (rs)+20% berseem hay (bh), while in the other groups the rations consisted of dm basis of 40% cfm+20% rs+40...

We describe a general approach for using linearizing feedforward control terms for large degree of freedom (dof) multi-limb robots operating in scenarios involving motion and force constraints and under-actuated dofs arising from the task and the environment. Our solution is general and has low computational cost needed for real-time control loops. It supports the tuning of the feedforward term...

On a life-cycle basis, beef animals are able to consume large amounts of low-cost, low-quality forages relative to higher-cost concentrates compared with pigs and chickens. However, of the 3, beef is still more expensive to produce on a cost–per–edible pound basis. Accordingly, there is need for genetic programs and management changes that will improve efficiency, sustainability, and profitabil...
