We analyzed and proved that this kind of mounting can cover all useful sky area and has much lower and smoother angular velocity and acceleration than the altazimuth one. IN THIS PAPER WE ALSO DISCUSSED THE RELATIONSHIP BETWEEN TWO MOST OFTEN USED ALT-ALT coordinate systems (SN-ALT-ALT, EW-ALT-ALT coordinate system) and the sidereal hour-angle coordinate system, the horizon coordinate system.

The hour hand: the circle of a clock face is divided by 12 hours, so each hour is 1/12 of the circle, and since a circle is 360 degrees, each hour is 360/12 degrees, so the angle of the hour hand is calculated this way, but as you all have noticed, no analog clock's hour hand stands still exactly on the current hour number until an hour is passed.

Pristine Li-Al LDHs are synthesized by hydrothermal process in different reaction conditions by varying the aging time for 1 and 24 hours. Both the Li-Al layered double hydroxides (abbreviated as Li-Al LDH1 and Li-Al LDH24 for aging time 1 hour and 24 hours, respectively) were modified by using sulphanilic acid sodium salt hydrate, modified agent to form modified Li-Al LDH1-SAS and Li-Al LDH24-SAS. The morphology of the pristine layered double hydroxides are investigated by using wide angle X-rays diffraction, scanning electron microscopy and particle size analyzer which indicates that the crystallinity and aspect ratio is increased with increasing the aging time from 1 hour to 24 hours. The particle size of Li-Al LDH24 and Li-Al LDH1 are found to be ~1000 nm and ~250 nm, respectively. Both the pristine and modified LDHs are characterized by XRD, FTIR spectra and thermogravimetric analysis.
