But we have to stop these threatening asteroids from hitting Earth so as to ‘save’ ourselves.

In some movies, we see a missile being launched straight towards a big asteroid. The latter then explodes and film usually ends. But in reality, it’s not that simple. Did you ever think what might happen to biggest remains of that big asteroid? Maybe it would go and enter Earth’s atmosphere or maybe not. If it does pass this first test, maybe it will cause big damages or maybe not. You will agree with me that man cannot take such a risk.

An idea suggests that if a small asteroid is indeed intending to hit Earth, an engine is to be anchored in it. This engine is simply going to push asteroid away.

Yet another strategy to put asteroid out of way is to attach solar sails to it. The ‘gentle’ pressure of sunlight on sails will deflect asteroid away from Earth.

Luckily an asteroid size of a football field manages to hit Earth only every thousand years or so but mind you I do not know when such an asteroid did hit Earth last.

As peak height is related with carrier-gas rate, wide peaks eluted later will be much sharper. This allows a better identification of low concentrations (increase in analysis accuracy);

Attainment of symmetrical peaks also in case of nonlinear adsorption isotherm, as rear of band is at a higher pressure than front;

The substantial enrichment, increase in concentration of component in center of band is conditioned by compression of band both as a consequence of moving pressure gradient compared with initial sorption pressure, and as a consequence of presence of moving gradient of optimal linear speed accompanying band of components being analyzed from inlet to outlet of chromatographic column during while analysis cycle (increase in efficiency of separation of components);

The pressure of gas in column can be changed almost instantaneously and equilibrium can be attained in a very short time. Pressure re-regulation excludes necessity of long "periods of cooling" of column (express - analysis, economy of electricity), while temperature increase programming may either cause evaporation of stationary phase, which "flies out" of column, or destroy it chemically to various molecules, which also will soon come out by carrier-gas. The repetitive cycles of heating and cooling may cause compression of solid support particles during expansion, followed by destruction (crumbling) during compression, which leads to a progressive change of permeability.
