OBJECTIVES With nuclear technology rapidly taking the spotlight in the last 50 years, radiation accidents seem to be a harsh reality of the modern world. The Mayapuri Radiation accident of 2010 was the worst radiation accident India has yet dealt with. Two years thereafter, we designed a study to assess the awareness and practices regarding radioactive waste among scrap dealers aiming to assess...

The agriculture sector has great potential to contribute to the mitigation of greenhouse gas emissions through changes in agricultural management and land use. However, the technical potential for agricultural mitigation has yet to translate into actual emission reductions due to considerable constraints to the generation of emission offsets through agricultural projects. These constraints incl...

BACKGROUND Nuclear accidents and terrorism presents a serious threat for mass casualty. While bone-marrow transplantation might mitigate hematopoietic syndrome, currently there are no approved medical countermeasures to alleviate radiation-induced gastrointestinal syndrome (RIGS), resulting from direct cytocidal effects on intestinal stem cells (ISC) and crypt stromal cells. We examined whether...

With the advance of autonomous systems, security is becoming most crucial feature in different domains, highlighting need for protection against potential attacks. Mitigation these types attacks can be achieved using embedded cryptography algorithms, which differ performance, area, and reliability. This paper compares hardware implementations eXtended Tiny Encryption Algorithm (XTEA) Advanced S...

The problem of soft errors caused by radiation events are expected to get worse with technology scaling. This thesis focuses on mitigation of soft errors to improve the reliability of memory caches. We survey existing mitigation techniques and discuss their issues. We then propose 1) a technique that can mitigate soft errors in caches with lower costs than the widely-used Error Correcting Code ...

An experimental approach to road mitigation that maximizes inferential power is essential to ensure that mitigation is both ecologically-effective and cost-effective. Here, we set out the need for and standards of using an experimental approach to road mitigation, in order to improve knowledge of the influence of mitigation measures on wildlife populations. We point out two key areas that need ...

The inclusion of a charge injection structure on a charge coupled device (CCD) allows for the mitigation of charge transfer losses caused by radiation induced charge trapping defects. Any traps present in the pixels of the CCD are filled by the injected charge as it is swept through the device improving the charge transfer efficiency in the subsequent acquired images. To date, a number of CCD t...

BACKGROUND Several clinical trials indicate that intracoronary radiation is safe and effective for treatment of restenotic coronary arteries. We previously reported 6-month and 3-year clinical and angiographic follow-up demonstrating significant decreases in target lesion revascularization (TLR) and angiographic restenosis after gamma radiation of restenotic lesions. The objective of this study...

The process of radiotherapy (RT) is complex and involves understanding of the principles of medical physics, radiobiology, radiation safety, dosimetry, radiation treatment planning, simulation and interaction of radiation with other treatment modalities. Each step in the integrated process of RT needs quality control and quality assurance (QA) to prevent errors and to give high confidence that ...
