What is diffusion, and how would you expect it to be affected by temperature and molecular weight? What is the major factor that affects diffusion? How does molecular weight (size of a molecule) influence its rate of diffusion? What are some factors that can alter the speed of diffusion?
Which lipoprotein particles contain "bad" and "good" cholesterol, and why are these terms used? How fiber can help reduce your blood cholesterol? Why is it important to avoid saturated fat and cholesterol? What can you do to minimize your saturated fat and cholesterol intake?
The force of the impact — if the particles hit with greater force, more energy is transferred to an object. These factors are determined by how many air particles there are in an area and how fast they are moving. If there are more particles, or if they are travelling more quickly, th...
In Thailand, and SE Asia as a whole, large populations are affected by biomass-derived haze events, and thus, it is noteworthy that few epidemiological and experimental (in vitro and in vivo) studies have been conducted in this region to identify what risks may be posed to health; further ...
"How gold, orange, or red the moon appears during a total lunar eclipse depends on how much dust, water, and other particles are in Earth's atmosphere"according to NASA scientists. Other atmospheric factors such as temperature and humidity also affect the moon's appearance during a lunar ecli...
The aurora are caused by solar storms that throw vast numbers of fast-moving electrons and protons away from the sun in a twisting mass of electric and magnetic fields. These microscopic particles typically take two days to travel 150 million kilometers from the sun to Earth. These energetic ...
Temperature and humidity: for high temperature areas such as ship engine vessels, the high temperature resistance of the filter screen should be considered. Fiberglass filters are usually able to withstand higher temperatures, can effectively filter salt spray in engine ventilation systems, and will not...
A 2018 how-to about secure disposal of a hard drive that included my recap of taking a crowbar to a drive in my driveway, leaving the pavement “flecked with small bits of drive platter mixed with finer particles of destroyed circuitry — a sort of cybernetic sand that I had to sweep ...
Plastic has become indispensable for human life. When plastic debris is discarded into waterways, these items can interact with organisms. Of particular concern are microscopic plastic particles (microplastics) which are subject to ingestion by several t
permeability of the cores. The smaller the particle size, the lower the permeability and better DC bias characteristics, but at a higher cost. The individual powder particles are insulated from one another, allowing the cores to have inherently distributed air gaps for energy storage in an ...
