Expander who drives a electromotor to generate electricity is the core of low-temperature waste heat recovery equipment. At present, domestic expanders on waste heat recovery system mostly come from exploration, research and improvement on the existing models of screw expanders and scroll expanders, which has complex structures and high costs. Against the shortcomings above, we researched and d...

background: catheter ablation is widely used for treatment of atrial fibrillation. the use of fluoroscopic and non-fluoroscopic mapping systems in catheter ablation is common. this study conducted to investigate the safety and effectiveness of navx non-fluoroscopic mapping system.   methods : in this study, the appropriate electronic databases including cochrane library and ovid medline searche...

There are numerous active and abandoned waste sites in the US and worldwide. Post‐closure development of these sites is desirable from an environmental, societal and economical perspective. However, the post‐closure development of landfills presents many challenges. A major challenge is the generally soft nature of the municipal solid waste (MSW) and the high pote...

This paper describes the general system for regulation of disposal of solid, long-lived radioactive wastes. It outlines the relevant Government policy, the framework of legislation and arrangements for implementation, the associated guidance produced by regulatory bodies and the approach to assessment by regulators of a safety case for radioactive waste disposal. Also, for the purposes of discu...

Feed waste results in increased production costs to the cage fish farming industry and produces negative environmental impacts. A computerized system, consisting of digital scanning sonar and current meter, was developed for monitoring, assessment, and optimization of the fish feeding process. The system can detect and monitor quantity and direction of wasted food pellets and also predict the t...

In this paper, a new guidance law is designed to improve the performance of a homing missiles guidance system in terminal phase. For this purpose first of all, the two dimensions equations of motion are formulated, then the approximation dynamic of missile control loop is added to these equations which are nonlinear whit unmatched uncertainty. Then, a new adaptive back-stepping method is develo...

Clinical practices surrounding the current Ebola epidemic have been center stage in discourse concerning research and practice of care. As the medical community becomes more sophisticated in understanding the many facets of treating and containing this virus, the Nebraska Biocontainment Unit Q6 has identified Ebola medical waste disposal as a key area of concern for U.S. hospitals. The requirem...

  Current World Health Organization and Centers for Disease Control and Prevention guidance for the disposal of liquid waste from patients undergoing treatment for Ebola virus disease at hospitals in the U.S. is to manage patient excreta as ordinary wastewater without pretreatment. The potential for Ebolavirus transmission via liquid waste discharged into the wastewater environment is currently...
