Abstract We examined the agreement between heart rate deflection point (HRDP) variables with maximal lactate steady state (MLSS) in a sample of young males categorized to different body mass statuses using index (BMI) cut-off points. One hundred and eighteen (19.9 ± 4.4 years) underwent standard running incremental protocol individualized speed increment 0.3 1.0 km/h for HRDP determination. was...

Creating an object-oriented design from user requirements, given as a set of use-cases, means deriving a detailed class structure that can support an implementation of those requirements. We introduce here the Augmented Finite-State (AFS) model for a set of use-cases. An AFS model of a single usecase U incorporates the inputs, outputs, and operations for each interaction in U , including the ”i...

Nonpoint source nitrogen is recognized as a significant water pollutant worldwide. One of the major contributors is agricultural drainage line water. A potential method of reducing this nitrogen discharge to water bodies is the use of immobilized denitrifying sludge (IDS). Our objectives were to (1) produce an effective IDS, (2) determine the IDS reaction kinetics in laboratory column bioreacto...

A single-fibre microfiltration system was employed to investigate the importance of various operating and sludge property parameters to the membrane fouling during sludge filtration. The sludge was obtained from a submerged membrane bioreactor (SMBR). A series of comparative and correlative filtration and fouling tests were conducted on the influence of the operating variables, sludge propertie...

The present work studied the application of membrane bioreactor (MBR) for tapioca wastewater processing that contained chemical oxygen demand (COD) ranging from 4000-9000 mg/L. A preliminary study was initially conducted in order to evaluate membrane performance with respect to its flux with MLSS concentration ranging from 4,500 to 10,500 mg/L. It was clear that fouling was observed during the ...
