its urgent STCL

No it can not adjust …. You can book loss on assets under P & L A/c.

unabsorbed depreciation only can carry forward.

No doubt it can be set-off as there is no such restriction

If STCG on shares is of specultive nature then setoff is not allowed. OTHERWISE IT IS ALLOWED.

stcl on depricialble assets is pure business loss, it has to be adjusted with business profit of the year, no need to carry forward, if there is no profit in the year, then only one has to carry forward.
