PM Fine Standards and Implied Modeling/Analysis Needs

Study of SESAR implied safety validation needs

Safety validation of changes to an individual organization’s local ATM system has become common practice in Europe. However, the SESAR program is planning changes in air traffic operations in Europe that go much further than changes to a local ATM system. This paper identifies the issues on which safety validation approaches need extensions, in order to move from safety validation of changes to...

Hormesis for fine particulate matter (PM 2.5).

The hypothesis of hormesis - that substances that harm health at high exposures can reduce risks below background at low exposures, e.g., if they activate defenses without overwhelming them - becomes important for practical policy making if it holds for regulated substances. Recently, the U.S. EPA concluded that reductions in ambient concentrations of fine particulate matter (PM2.5) in air caus...

Seasonal Study of Dust Deposition and Fine Particles (PM 2.5) in Iran Using MERRA-2 Data

The research results indicated that wet and dry dust deposition is a function of geographical characteristics. The seasonal wet and dry dust deposition and Fine Particles (PM 2.5) correlation in Iran with elevation, latitude and longitude results that the maximum correlation belongs to height, followed by latitude and longitude; meanwhile height and latitude are strongly and reversely correlate...

Methods of Representing Implied Author and Implied Reader in GavKhuni and its Film Adaptation

Implied author and implied reader are components of a narrative structure, playing a crucial role in illuminating hidden elements within a text. Therefore, studying these elements in literary works can expose the underlying layers of narration and open up new critical outlooks to the readers. Furthermore and in cases of cinematic adaptations, it explains whether this was the novel or the film t...
