‎let $l$ be a lie algebra‎, ‎$mathrm{der}(l)$ be the set of all derivations of $l$ and $mathrm{der}_c(l)$ denote the set of all derivations $alphainmathrm{der}(l)$ for which $alpha(x)in [x,l]:={[x,y]vert yin l}$ for all $xin l$‎. ‎we obtain an upper bound for dimension of $mathrm{der}_c(l)$ of the finite dimensional nilpotent lie algebra $l$ over algebraically closed fields‎. ‎also‎, ‎we classi...

Functional brain imaging with magnetic resonance is a useful research tool for showing regional metabolic changes with ongoing brain activity. Use of functional imaging to study the anatomy and function of various brain areas has recently been applied to the examination of the emotional life of patients including those with anxiety, panic, or depression. The application of this technology to th...

Lie detection techniques are utilized by investigating agencies in a wide variety of fields, such as Defence, Secret Services, Terrorism, as the veracity of statements cannot be taken at face value.
