An object-oriented development environment to optimally design cyclic storage systems
Cyclic storage system (CSS) is defined as physically interconnected and operationally integrated surface water and groundwater subsystems with full direct interactions between the subsystems. Mathematical development and implementation of a CSS model is very complex and all previous works are fully case dependent with a minimum possibility of generalization. This article proposes an integrated ...

HDPE - A Hydrocarbon Resistant Membrane?
Most brownfield redevelopment and environmental protection applications require the use of a hydrocarbon resistant membrane. However, each membrane material will vary in its ability to resist chemical attack and its effectiveness as a barrier to permeation. It is essential that a barrier material prevents the migration of contaminants, thereby not harming the surrounding environment or building ...

Sustainable development: paradigm or paranoia?
Sustainable development is the globally embraced paradigm for integrating environment and development policies. Agreement ends with attempts at quantifying the elusive notion of sustainability. A contentious debate among "environmentalists" and "environmental economists" has brought about a confusing proliferation of indicators and policy advice on sustainable development. ...

Converged Security Solutions: The Time is Now
Up until the lockdown at least, I have been a regular attendee at the world’s leading international security exhibitions and conference. One thing is becoming more and more clear – the convergence of traditional physical security solutions and cybersecurity is vital in the modern age. End users now expect holistic solutions that address all threats – whether they be from ...

Application of a revised Water Poverty Index to target the water poor
The Water Poverty Index (WPI) has been recognized as a useful tool in policy analysis. The index integrates various physical, social and environmental aspects to enable more holistic assessment of water resources. However, soundness of this tool relies on two complementary aspects: (i) inadequate techniques employed in index construction would produce unreliable results, and (ii) poor ...

Application of the Water Poverty Index in border
colonias of west TexasThis study applied the Water Poverty Index (WPI) in border colonias of west Texas. The colonias are mostly unincorporated communities located primarily in New Mexico and Texas along the border with Mexico and are characterized by high poverty rates and sub-standard living conditions. In Texas, access to drinking water and sanitation services has been identified as one of the most significant ...

IIoT Sensors and Industry Use Cases
The term “Internet of Things”, or IoT, has been making waves in the industrial, commercial, manufacturing and consumer markets over the past years since the concept was formerly introduced in 2012 by the The Global Standards Initiative on Internet of Things (IoT-GSI). Coined as a term for computing devices that can perceive the world without relying on humans for data input, the ...

Stochastic simulation methodology for resilience assessment of water distribution networks
Water distribution systems enable social and economic development and sustain people quality of life. However, these systems face significant performance challenges including ageing, natural disruptive events, and man–made disruptions. Physical protection of networked infrastructure distributed over large geographical areas is unfeasible. A cost–effective alternative is to enhance the water ...

Verify and Validate - Temperature Monitoring for AGF
Artificial Ground Freezing (AGF) is a specialized technique commonly used to control groundwater flow and settlement during underground construction. Generally, a gallery of well loops are sunk into the soil and circulated with brine fluid to freeze and subsequently support the soil structure. While the soil-thermal dynamics can be modeled to characterize and forecast changes in the soil ...

Converting the dreaded PCBs into useful commodities
For decades polychlorinated biphenyls (PCBs) have been high on the list of toxins the public fears. A new vitrification technology is claimed to be able to completely destroy PCBs and other toxins in contaminated sediment by meltingit into a glass aggregate product that can be used in the construction industry. This process, developed by Minergy Corp., costs about as much as landfilling, without ...

A new strategy for treating a cotton dyeing wastewater – integration of physical-chemical and advanced oxidation processes
New strategies were herein applied for treating a cotton dyeing wastewater: coagulation/flocculation followed by Fenton’s oxidation – approach 1, Fenton process per se – approach 2, and Fenton followed by coagulation/flocculation – approach 3, aiming reducing chemicals consumption. Regarding the cost analysis, which is crucial for deciding on the best strategy to implement, it was found that ...

Improvements in microscopy technology have focused on elusive details in biology
In the late 17th century, Dutch businessman Anthoni van Leeuwenhoek began to use the first microscope to study a very small world and discovered a colorful world composed of protists, bacteria, and other organisms that had never been seen before. Later generations of scientists have developed more sophisticated means to explore microcosms, bringing many of the mysteries of the biological field ...
