The work is devoted to the problem of flexible small-scale production galvanized steel various sizes on a continuous hot-dip galvanizing unit with varying productivity. main focus heat treatment strip, requirements for which limit In conditions disturbances, it necessary proactively control using models, or reduce speed strip ensure that are met. Unlike most works control, this focuses cooling....

In the paper the methodology and test results of field and laboratory corrosion tests of steel earthing rods with zinc galvanized coatings and copperbonded coatings are described. The corrosion rate and level of corrosion damage of earthing rods with two different protective coatings have been compared as well some conclusions related to reliability and assessment of technical “life time” of st...

The field of HIV biology has been galvanized by the discovery of innate APOBEC3 cytidine deaminases, which pose powerful barriers to the replication of HIV and other retroviruses. Rapid progress has been made in understanding their mode of action, intriguing regulation within cells, expanded range of retroviral targets, and the counterstrikes utilized by retroviruses against them. While scienti...

Naegleria fowleri causes acute and fulminant primary amoebic meningoencephalitis. This microorganism invades its host by penetrating the olfactory mucosa and then traveling up the mesaxonal spaces and crossing the cribriform plate; finally, the trophozoites invade the olfactory bulbs. During its invasion, the protozoan obtains nutrients such as proteins, lipids, carbohydrates, and cationic ions...

There is a need for alternative catalysts for oxygen reduction in the cathodic compartment of a microbial fuel cell (MFC). In this study, we show that a bipolar membrane combined with ferric iron reduction on a graphite electrode is an efficient cathode system in MFCs. A flat plate MFC with graphite felt electrodes, a volume of 1.2 L and a projected surface area of 290 cm2 was operated in conti...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...

The demand for high performance cast aluminum alloy components is often disturbed by increasing impurity elements, such as iron accumulated from recycled scraps. It is strongly required that coarse plate-like iron compound of β-Al5FeSi turns into harmless form without the need for applying refining additives or expensive virgin ingots. The microstructural modification of Al-7mass%Si alloy bille...

AIMS To determine the contribution of potential modes of action of a Bacillus cereus aquaculture biological control agent in inhibition of the fish pathogen, Aeromonas hydrophila. METHODS AND RESULTS When B. cereus was tested in plate well inhibition studies, no production of antimicrobial compounds was detected. Bacillus cereus had a high growth rate (0.96 h(-1)), whereas Aer. hydrophila con...
