Occupational Safety and Health Administration Combustible Dust: An Explosion Hazard. Any combustible material can burn rapidly when in a finely divided form. If such a dust is suspended in air in the right concentration, under certain conditions, it can become explosible. Even materials that do not burn in larger pieces (such as aluminum or iron), given the proper conditions, can be explosible in dust form.

What are the Effects of Dust on the Lungs? The air reaches the tiny air sacs (alveoli) in the inner part of the lungs with any dust particles that avoided the defenses in the nose and airways. The air sacs are very important because through them, the body receives oxygen and releases carbon dioxide.

What are the Effects of Dust on the Lungs? The lungs are constantly exposed to danger from the dusts we breathe. Luckily, the lungs have another function - they have defense mechanisms that protects them by removing dust particles from the respiratory system. For example, during a lifetime, a coal miner may inhale 1,000 g of dust into his lungs.

Cantor dust George Cantor (1845-1918) constructed the Cantor dust. The curve is a base motif fractal which uses a square segment as base. The motif is to divide the square into nine equal parts and let only the outer four remain: The fractal dimension of the Cantor dust is equal to log4/log3, what is about 1.26186.A variant on this curve is given by the box fractal: divide the square into 9 equal parts and let the five diagonal parts remain.This curve is also named the anticross-stitch :he motif is to divide the square into nine equal parts and let only the outer four remain: The fractal dimension of the Cantor dust is equal to log4/log3, what is about 1.26186.

Demolition Dust: Hazards and Control Dust is a generic term for minute solid particles, typically less than 500 microns in diameter. In construction and demolition projects, dust particles are created in a wide range of sizes. Larger, heavier particles tend to settle out of the air, while smaller, lighter solids may hang indefinitely.

'Smart dust' aims to monitor everything Smart dust (minus the 'dust') Despite the recent excitement, there's still much confusion in the computing industry about what exactly smart dust is. For starters, the sensors being deployed and developed today are much larger and clunkier than flecks of dust.
