Parallel market trends In contrast, the parallel (black) market saw a decline. The naira closed May at N1,630/$1, down from N1,610/$1 at the start of the month. This marks a 1.24% decline from the ...

Cooling is also dealt with differently in space than on Earth. The problem with cooling is that space is a vacuum, so the classical convection cooling fan doesn’t work. “Cooling is done through heat ...

Convection takes place in fluids, as hotter fluid rises to the top of a system and cooler fluid sinks, creating convection currents. Radiation, meanwhile, takes place through electromagnetic waves ...

The image above, provided by NASA, highlights how all three heat-transfer methods (conduction, convection, and radiation) work in the same environment. What is Conduction?

Like radiation, though, it’s not super important when it comes to blowing on food, for one simple reason: it depends on colliding atoms, and in gases, those atoms don’t collide all that often.

Two parallel one-kilometre-long access tunnels link the facility to the surface. Most of the short-lived waste deposited in the SFR - which began operations in 1988 - comes from Swedish nuclear power ...
