To revise / revisit basic control schemes covered in the second year control course (Process Control I). Schemes to be discussed are: • Feedback control • Feedforward Control • Cascade Control • Ratio Control For each scheme a typical process example is used to highlight the application of the methodology. On completion of this section of the course you should have an awareness of a common proc...

The map of nutrition, evident in the structure of any course or textbook, derives from theses that framed a science begun in the 1840s, developed until the 1940s, and consolidated until now. Nutritionists now are as perplexed as the explorers of half a millennium ago, who continued to use maps that did not fit the wider world they found. Until the 1600s, alternatives to Ptolemaic cosmology rema...

Enterococci from pigs in Denmark, Spain, and Sweden were examined for susceptibility to antimicrobial agents and copper and the presence of selected resistance genes. The greatest levels of resistance were found among isolates from Spain and Denmark compared to those from Sweden, which corresponds to the amounts of antimicrobial agents used in food animal production in those countries. Similar ...

l-theanine is a water-soluble non-proteinous amino acid mainly found in green tea leaves. Despite the availability of abundant literature on green tea, studies on the use of l-theanine as a feed additive in animals, and especially broilers are limited. The objective of this study was, therefore, to evaluate the effect of different dietary levels of l-theanine on meat quality, growth performance...

Battery Recycling In article number 2211946, Bartosz A. Grzybowski and co-workers present a one-pot separation of metals from spent lithium-ion batteries. Three liquid layers occupy different segments the rotating cylindrical vessel are intensely stirred to move selected components between layers. only ten minutes, all cobalt manganese migrate feed acceptor layer (red), while lithium nickel rem...

During the reproductive season, sea turtles use a restricted area in the vicinity of their nesting beaches, making them vulnerable to predation. At Raine Island (Australia), the highest density green turtle Chelonia mydas rookery in the world, tiger sharks Galeocerdo cuvier have been observed to feed on green turtles, and it has been suggested that they may specialise on such air-breathing prey...

Fibropapillomatosis (FP) is a neoplastic disease that affects marine turtles worldwide, especially green sea turtles (Chelonia mydas). FP tumors can develop on the body surface of marine turtles and also internally in the oral cavity and viscera. Depending on their quantity, size and anatomical distribution, these tumors can interfere with hydrodynamics and the ability to feed, hence scoring sy...
