For example, the feedrate and accuracy of a weighbatching system’s conveyor or feeder doesn’t exclusively determine the system’s overall capacity and accuracy. Other factors that may affect productivity and success include material delivery method, infeed rate, surge vessel capacity, weighing equipment location in relation to mixers, hopper and chute design based on the material’s physical prop...

The relationship between working chute temperament and beef carcass quality traits were measured on 183 crossbred feedlot steers. Steers were weighed and sorted into 16 pens and weighed every 28 days. Temperament was evaluated as exit velocity (EV), chute score (CS), and catch score (CAPS). Tissue samples were collected for DNA profile including docility (IGENITY®, Merial Limited, Duluth, GA, U...

Relationships between behavioral and physiological symptoms of preslaughter stress and LM Warner-Bratzler shear force (WBSF) were investigated using Bos taurus steers (n = 79) and heifers (n = 77). Measurements of heart rate, respiration rate, rectal temperature, and concentrations of serum cortisol and plasma epinephrine were used as indicators of stress associated with physical handling and c...

In this work, the signals generated by grain-to-base multiple impacts of three different granular materials flowing along an inclined chute and characterized unsteady-state conditions are investigated through discrete element method (DEM). The effect grain-size angularity grains taken into account. Various instants flows studied, focusing in particular on analysis signal produced passage materi...

Stepped chute flows are characterised by intense turbulence and strong flow aeration (Fig. 1), but most studies did not investigate the turbulence characteristics. Detailed air-water flow properties were measured in skimming flow on a stepped chute (θ = 16o, h = 0.05 m). Longitudinal oscillations of depth-averaged flow properties were observed with a wave length of about two step cavity lengths...

Experimental observations, model evaluations, and expert judgements are combined to make predictions of snow velocity in large chute experiments. Different experimental treatments, namely the environmental conditions snow density and snow-surface temperature, affect all aspects of this inference. We show how treatments can be incorporated into our judgements regarding the uncertain parameters o...

Ore passes are often the main part of sublevel caving transportation systems, and they use gravity to move material lower levels in mine. During operations, ore pass structures exposed risk stoppage failure, leading a long-term reduction operational capacity affecting productivity. The failed can be restored or rehabilitated, but rehabilitation cost is normally high time restore usually long. T...

This paper presents a game intended to train teams that have both individual and teams goals to negotiate collaboratively in order to reach the team goal in the best way possible. We consider self-managing teams, i.e., teams that do not have a hierarchical structure. The importance of the team goal in comparison to their individual goals is touched upon, as are various conflicts that can occur ...
