Air quality and health impacts in the Eastern Mediterranean Region: an eye on COVID-19.

Air quality is intimately linked to human activities, climate, atmosphere and ecosystems. Many of the anthropogenic contributors to air pollution are also sources of greenhouse gases including CO2 and other short-lived climate pollutants, such as Ozone and black carbon, which greatly contribute to the climate change phenomenon and its adverse effects on human health. Unfortunately, fragile and dry ecosystems prevailing in most of our countries in the Eastern Mediterranean Region may be implicated for exacerbation of this air pollution and climate change dilemma even more severely.

Evaluation of neutron and gamma dose in a new deuterium-deuterium fusion neutron generator facility using MCNP and experimental methods.

A deuterium-deuterium (D-D) neutron generator facility has been developed with a wide range of applications in mind. D-D neutron generators provide a safe, convenient, and low-cost solution for the production of thermal, epithermal, and fast neutrons for laboratory and industrial applications. The regulatory burden for operating one of these generators is small as it contains no radioactive material and produces no radiation when turned off.

Set-membership methodology for model-based prognosis.

This paper addresses model-based prognosis to predict Remaining Useful Life (RUL) of a class of dynamical systems. The methodology is based on singular perturbed techniques to take into account the slow behavior of degradations. The full-order system is firstly decoupled into slow and fast subsystems.
