Hydraulic Characterization of Interlocking Concrete Permeable Pavement
The environmental benefits of permeable pavements are vast and include stormwater quantity reduction, stormwater quality improvement, urban heat island mitigation, and groundwater recharge, among others. Permeable Interlocking Concrete Pavements, PICP explicitly infiltrate water, a new concept to …

Hydraulic Design of Interlocking Concrete Permeable Pavement
… focus of this thesis is on the structural BMP, Permeable Interlocking Concrete Pavement (PICP). PICP is a type of pervious pavement that will increase the amount of water infiltrated through joint spacing filled with open graded aggregate above an open-graded base and sub-base, creating a …

Turbulent drag reduction by anisotropic permeable substrates
… is to answer the question: `can anisotropic permeable substrates reduce turbulent skin-friction drag?' The first part of the thesis aims to extend the existing understanding on how complex surfaces of small texture size can reduce drag. We show that the effect of these surfaces can be reduced …

Enhancement of fine particle deposition to permeable sediments
… flat sediment beds reinforces the importance of permeable sediments to the mediation of transport from the water column to the sediment bed.

Experimental investigation on turbulent flow overlying permeable walls
A turbulent flow overlying a permeable wall can be subdivided into two distinct flow regions separated by a permeable interface. The first is the surface (or free) flow region, which overlies the interface. The second is the subsurface (or pore) flow region, which occurs within the permeable wall. …

Enhancement of fine particle deposition to permeable sediments
Predictions of deposition rate are integral to the transport of many constituents including contaminants, organic matter, and larvae. Review of the literature demonstrates a general appreciation for the potential control of deposition by bed roughness, but no direct tests involving flat sediment …

The Evaluation of Permeable Cementitious Media for Nutrient Removal
… with the quality of aquatic and human life. Permeable pavement systems have been studied for contaminant removal, but there are limitations to the current state of knowledge. Laboratory studies were utilized to fundamentally characterize permeable cementitious media for the removal of …

ISPH Modelling of Solitary Wave Interaction with Permeable Beaches
… applied to simulations of solitary wave runup on permeable slopes. In these simulations, triangle and parallelogram porous structures with various mean grain sizes were focused. Two different scale slopes were considered to generate both nonbreaking and breaking waves. For nonbreaking waves, runup …

Artificial Intelligence-Based Prediction of Permeable Pavement Surface Infiltration Rates
Permeable pavements are a type of low impact development technology that is an alternative to conventional asphalt pavements. These pavements are used to address urban stormwater runoff concerns through infiltration and storage. Overtime, sediments carried by stormwater runoff degrade the …

Development of Novel, Brain Permeable, mPGES-1 Inhibitors for Inflammatory Conditions
<p>Prostaglandin E2 (PGE2) is a potent proinflammatory lipid signaling molecule produced downstream of the cyclooxygenase (COX) cascade. The COX pathway has long been implicated for its role in inflammation, with drugs like aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) …

Design Methodology for Permeable Reactive Barriers Combined With Monitored Natural Attenuation
Permeable reactive barrier (PRB) technology is increasingly considered for in situ treatment of contaminated groundwater; however, current design formulas for PRBs are limited and do not properly account for all major physical and attenuation processes driving remediation. This study focused on …

The link between Permeable Interlocking Concrete Pavement (PICP) design and nutrient removal
… associated with the construction of ‘hard' impermeable surfaces such as roofs and roads, results in increased stormwater runoff peak flows and volumes and their associated pollutants into downstream receiving waters compared with the pre-development state unless mitigated through Sustainable …

The impact of unwashed aggregate on water quality emanating from permeable pavements
… runoff, through a multi-objective approach. Permeable pavement systems (PPSs) are one of the most widely-adopted SuDS technologies in South Africa. South Africa is a water scarce country and the sustainable provision of water to its citizens is one of the most significant challenges facing …

Glutamate Excitotoxicty Activates a Novel Calcium Permeable Ion Channel in Cultured Hippocampal Neurons
… we report the discovery of a novel calcium permeable ion channel that is activated by excitotoxic glutamate injury and mediates a calcium current that is an early initiating step in causing neuronal death. Blocking this calcium permeable channel with high concentrations of Zn2+ or Gd3+ by …
