Andrews's recent proof of the Mills-Robbins-Rumsey conjectured formula for the number of totally symmetric self-complementary plane partitions is used to derive a new multi-variate constant term identity, reminiscent of, but not implied by, Macdonald's BC,-Dyson identity. The method of proof consists in translating to the language of constant terms an expression of Doran for the desired number ...

Around 40% of electricity in the UK is currently generated by coal-fired power stations. Coal-fired power stations nowadays are required to operate more flexibly with more varied coal specifications and regularly use coal with higher volatile contents and biomass materials; this can increase the risks of pressurisation or fires in milling plants. The power stations are also obliged to vary thei...

Generally, crash stops are performed to obtain measurement of charge filling and slurry loading. The crash stop involves running the mill under steady state then cutting off all feed streams to the mill as it is being stopped. Sufficient time is required to obtain all the important measurements correctly during the crash stop. The mill filling should be measured at a minimum of 3 points along t...

Mill scale is one of the byproducts which produced during processing steel. It rich in iron (≥70%), has lower impurities and a stable chemical composition. The present research studies effects partial replacement ore with different proportions mill on sinter charge. results this study showed that an increase substitution by at 3%, rate production increases from 21.94 to 25.50 ton/m2/day (16.2%)...

Discrete Element Method (DEM) is a powerful tool for simulating different types of mills. It also used computing particles such as rocks, grains, and molecules. DEM has been widely in the field rock mechanics. In present work, DEM approach applied to model milling media (powder balls) inside planetary ball mill estimate distribution dry powder during milling. fact, efficiency DEM strongly depen...

Rhythmically active motor circuits are influenced by neuronally released and circulating hormone modulators, but there are few systems in which the influence of a peptide hormone modulator on a neuronally modulated motor circuit has been determined. We performed such an analysis in the isolated crab stomatogastric nervous system by assessing the influence of the hormone crustacean cardioactive ...

Neuromodulation changes the cellular and synaptic properties of neurons, thereby enabling individual neuronal circuits to generate multiple activity patterns. However, distinct modulatory inputs could conceivably also cona different motor circuits to generate similar activity patterns. Using the isolated stomatogastric ganglion (STG) of the crab Cancer borealis, we showed previously that pyroki...
