Addiction to Chlorodyne

Dilatation of the Pupil in Chlorodyne Poisoning

In two of my cases the medical attendant first called in rejected the diagnosis of opium or chlorodyne poisoning on account of the condition of the pupils. The composition of cholorodyne varies with the fancy of each manufacturer. In one sample of Collis Brown's preparation 4 grs. of morphia and the equivalent of 25 minims of B. P. Acidum Hydrocyanicumdilufcum were found in one ounce of the mix...

Fatal addiction to trichloroethylene.

Trichloroethylene inhalation is a common industrial hazard that involves a risk of addiction. In the present case there was evidence of indulgence of addiction at work but not at home.

Addiction to Internet, Modeling and Control

In this paper, we propose a  mathematical model of addiction to Internet. We investigate the effect of educational programs on the control of the addiction. We compute basic reproduction number. By using Chavez-Song theorem, we show the occurrence of backward bifurcation. We prove the global stability of the equilibrium points using geometric stability method and Lyapunov function.
