The aim of this research work was to investigate on the ball filling estimation of Miduk semi-autogenous (SAG) Mill via an utilized method. Miduk copper concentrator is located in Kerman Province, Iran, and its size reduction stage includes one gyratory crusher which feeds one SAG mill (9.75 dia.(m)*3.88 length(m)) following two parallel ball mills (5dia.(m)*7lenght(m)). After SAG mill, a tromm...

the ball and beam system is one of the most popular laboratory setups for control education. in this paper, we design a fuzzy pd cascade controller for a ball and beam system using asexual reproduction optimization (aro) technique. the ball & beam system consists of a servo motor, a grooved beam, and a rolling ball. this system utilizes a servo motor to control ball’s position on the beam. chan...

The woollen coat, for example, which covers the day-labourer, as coarse and rough as it may appear, is the produce of the joint labour of a great multitude of workmen. The shepherd, the sorter of the wool, the wool-comber or carder, the dyer, the scribbler, the spinner, the weaver, the fuller, the dresser, with many others, must all join their different arts in order to complete even this homel...

A disk Wang-Bézier type generalized Ball curve is a Wang-Bézier type generalized Ball curve whose control points are disks in a plane. It can be viewed as a parametric curve with error tolerances. In this paper, we discuss the problem of degree reduction of disk Wang-Bézier type generalized Ball curve, that is, bounding disk Wang-Bézier type generalized Ball curves with lower degree disk Wa...

We studied the interaction of human neutrophils with nylon wool in vitro and during filtration Ieukapheresis (FL) to better understand cellular events detrimental to neutrophils that occur during FL. When neutrophils purified from blood by gradient centrifugation and sedimentation were incubated with nylon wool in vitro, release of lysozyme from the cells occurred rapidly and to a degree that w...

An innovative lamb-feeding facility with a raised-slatted floor (RF) was designed and built for the purposes of concurrently roducing high-quality, high-value wool and large, lean lamb carcasses. A ration was formulated to provide a low rate of gain in rder that lambs attained slaughter weight (59 kg) when they were approximately 12 month of age because a 12-month fleece is prerequisite for hig...

By 2030, climate change is likely to have implications for the Australian wool industry, principally through effects on forage and water resources, land carrying capacity and sustainability, animal health, and competition with other sectors, in particular cropping. The nature and scale of these impacts will vary between the wool growing regions, depending on the manifestation of the climate cha...

serious restrictions on the extensibility of the spiral. I t may be calculated from columns 3, 4 and 5 of Table I that the cystine content of Fraction I corresponds to approx, only I cystine residue/3o non-cystine residues, whereas the average for wool is i :i6. This favours the possibility that the cystine is intra-linked in Fraction I and corresponds to the AB cystine fraction of PHILLIPS. Th...
