Medicinal plants offer diverse health benefits through biological active compounds, anti microbial effects that help treat diseases. Polluants contaminate medicinal plants through polluted soil, water, and air, or poor processing, with different concentrations.Different contributors include industrial emissions, pesticides, irrigation with polluted water, and environmental pollution e.g. Toxic/heavy metals such as cadmium (Cd), copper (Cu), lead (Pb), nickel (Ni), zinc (Zn), arsenic (As), and chromium (Cr), mangan...

Fine particles known as combustible dusts can cause explosions when they are suspended in the air under certain conditions. A dust explosion could result in severe fatalities, injuries, and structural devastation. The risk of such events can be reduced by knowing the flammability parameters and the physico-chemical analysis for combustible dusts, in order to take additional protective measures generated by the occurrence of these types of explosive mixtures. The purpose of this research was to identify the flammab...

The hydraulic systems used in the aviation industry use pressurized fluids that transmit energy to various driving systems of the aircraft (hydraulic motors, cylinders or hydraulic actuators). It is known that hydraulic fluids, along with the fuels used, present a potential risk of fire, which can lead to damages or the loss of the aircraft, often with very serious consequences. At the same time, in the event of a plane fire after the crash, hydraulic fluids can be an additional fuel source. For these reasons, the...
