With the aim to open a new window into corrosion processes this paper presents respirometric methods for real-time in situ monitoring of rates under immersion conditions. these techniques, sensitive, non-destructive rate measurements are possible on basically all metals and alloys. Different presented that enable monitor HER, ORR or both reactions simultaneously based amount evolved H 2 consume...

“Biosensors” are defined as sensors that allow the measurement and interpretation of the biological response of activated sludge to a known disturbance. The purpose of “biosensing” the activated sludge, on-line at the full-scale plant or off-line in lab-scale tests, is to obtain specific information about one or several activated sludge processes. This information can serve as plant performance...

The study focused on variable kinetics for substrate utilization, primarily addressing the following issue: Is variable process kinetics observed under different operating conditions and culture history (sludge ages), the result of changes inflicted on the metabolic machinery of the same microbial culture? Or, is this the result of a different microbial population selected under different opera...

Insect flight metabolism is completely aerobic, and insect resting metabolism is quite insensitive to atmospheric oxygen level, suggesting a large safety margin in the capacity of the tracheal system to deliver oxygen during flight. We tested the sensitivity of flight initiation and metabolism to atmospheric oxygen level in the libellulid dragonfly Erythemis (Mesothemis) simplicicollis using fl...

-The use of powdered activated carbon treatment (PACT), based on simultaneous adsorption and biodegradation, is effective for treating organic toxic pollutants, present in industrial wastewaters. Removal of phenol and aniline from aqueous solutions by biological treatment alone, by adsorption on powdered activated carbon (PAC) alone and by simultaneous adsorption and biodegradation were compare...
