Stormwater runoff is a known pollutant source capable of causing surface water degradation, especially in highly populated areas such as Central Florida. Wet detention ponds manage this stormwater, but most of the ponds do not remove enough nutrients, specifically nitrogen and phosphorus, to meet TMDL regulations. This paper presents the use of a Chamber Upflow Filter and Skimmer (CUFS) filled ...

Film-coating of seeds is a widely accepted technology in agriculture for effectively protecting germinating and seedlings against biotic abiotic stresses successfully delivering agro-chemicals, biomolecules, bio-inoculants to the rhizosphere region. The present experiments explored possibility using hydroxypropyl methylcellulose (HPMC) dextrin as film-coating agents impregnating maize seed with...

A model describing both physical and biological processes in Upflow Anaerobic Sludge Blanket (UASB) reactors was developed. The main objective of the modelling was to take into account the transient growth of the microorganisms from the start-up of the reactor until a steady state is reached. In addition, the model considers the degradation of the substrate and its reaction with the biomass, wh...

Water is arguably the most important constituent of microbial microhabitats due to its control of physical and physiological processes critical to microbial activity. In natural environments, bacteria often live on unsaturated surfaces, in thin (micrometric) liquid films. Nevertheless, no experimental systems are available that allow real-time observation of bacterial processes in liquid films ...

The aim of this paper was to synthesize and characterize microbial chitosan thin films for potential piezoelectric application. Microbial derived from the Aspergillus oryzae fungus via extraction deacetylation. Chitosan film characterized its surface morphology, chemical properties, tensile strength, topography. For application as a material, characteristics were presented in terms electromecha...

The interfacial instabilities important to the modeling of critical heat flux (CHF) in reduced-gravity systems are sensitive to even minute body forces, especially for small coolant velocities. Understanding these effects is of paramount importance to both the reliability and safety of two-phase thermal management loops proposed for future space and planetary-based thermal systems. Unfortunatel...

The prominent blue shifts of Ne viii associated with the junctions of the magnetic network in the quiet Sun are still not well understood. By comparing the coronal magnetic-field structures as obtained by a potential-field reconstruction with the conspicuous blue-shift patches on the dopplergram of Ne viii as observed in an equatorial quiet-Sun region, we find that most of the regions with sign...

Forced-convection boiling was investigated with a dielectric coolant (FC-72) in order to address some of the practical issues related to the two-phase cooling of multichip modules. The module used in the present study featured a linear array of nine, 10 x 10 mm, simulated microelectronic chips which were flush-mounted along a 20mm wide side of a rectangular channel. Experiments were performed w...

Ideal bacterial support medium for fixed film denitrification processes/bioreactors must be inexpensive, durable and possess large surface area with sufficient porosity. The present study has been focussed on removing nitrate nitrogen at two different nitrate nitrogen loading rates (60 (NLR I) and 120 (NLR II) mg l(-1)) from simulated aquaculture wastewater. Coconut coir fibre and a commerciall...
