Decontamination from Black Viruses Using Parallel Strategies
… In this way, we dramatically reduce the decontamination time, still keeping the spread (and the number of agents loss) asymptotically optimal. In the thesis, various protocols are proposed in meshes, tori, and chordal rings following the monotonicity principle (i.e., once a node is …

Decontamination method comparison testing using simulated contamination
Radiological decontamination of surfaces is challenging. Cleanup tasks are typically visual or even chemically measured, but radioactive contamination is invisible and measured at extremely low levels. Different contamination events have lead to the development of hundreds of decontamination …

Exploring the Decontamination Process for Reusable Medical Devices (RMDs)
<p><strong>Background:</strong> Decontamination of reusable medical instruments (RMDs) is today’s top eight patient safety concern (ECRI, 2018). Many healthcare organizations continue to be non-compliant on decontamination of RMD standards.</p> <p><strong>Purpose and Aims:</strong> The purpose of …

Chemical Treatment Approaches For Industrial Plant Decontamination: Mercury remedation
… and recycle. Economical and applicable chemical decontamination i.e. dissolution of elemental Hg should be studied to eliminate this problem to avoid mercury exposure to worker and environment. <br/>In this study, wet-based chemical approaches using KI/I2 solutions were studied for the recovery …

Remediation of spent oxalic acid nuclear decontamination solutions using ozone
… removed mechanically, chemically cleaning (i.e. decontamination) with oxalic acid is used to aid in the removal of residual quantities. Although oxalic acid works for cleaning the tanks, its downstream impacts are considered detrimental. To better understand and quantify the impacts, detailed …

Decontamination and Valorisation of a Corn-to-Ethanol Biofuel Waste Stream
… investigates the physiochemical characteristics, decontamination and valorisation potential of a tertiary waste stream (TWS) produced during a corn-to-ethanol whole stillage upgrading process. Rheological analysis revealed that TWS exhibits non-Newtonian, pseudoplastic behaviour driven by …

Cultivation of Palmaria palmata: spore release, vegetative propagation and decontamination techniques.
… meristematic tissue was also trialled alongside decontamination treatments. These experiments were subsequently up-scaled to flask culture and at-sea experiments. The main observation from the spore experiments was that an oomycete infection is highly prevalent and limits the production of this …

Chitosan Decontamination with Non-Thermal Nitrogen Plasma to Enable Internal Use
<p>Chitosan (CS) is a ubiquitous biopolymer and is recognized as a promising biomedical material. Potential medical applications for chitosan are extensive and many have shown impressive results. However, chitosan is clinically only used as a topical hemostatic agent due to an inability to …

An Investigation into the Decontamination of Carbon-14 from Irradiated Graphite
The decommissioning of nuclear power plants around the world will produce a major waste stream of irradiated graphite. Graphite has been used extensively as a reactor moderator and reflector material that becomes irradiated and contaminated over time. In the coming years ~250,000 tonnes of …

GENOMIC AND PHYSIOLOGICAL INSIGHTS INTO BACTERIAL HEAVY METAL RESISTANCE MECHANISMS FOR ENVIRONMENTAL DECONTAMINATION
The contamination of soils and waters with heavy metals (HM) such as chromium, copper, zinc and cadmium represents one of the most severe environmental challenges, posing risks to ecosystem balance and human health. Microorganisms and plants have evolved a range of mechanisms to tolerate, transform …
