Recent literature on Mexican industry has emphasized its uneven sectorial development: some sectors have been successful, while the rest remain well behind. Given these circumstances, the present paper proposes a particular division for Mexican industry in High-Tech and Low-Tech sectors. This division is based on technological capabilities for a particular sample of industries during the nineties and verified for statistical robustness using the discriminant analysis technique. Finally, the division is used for an empirical application in terms of profitability and market structure. The empirical results reveal a diverse behaviour of the High-Tech and Low-Tech groups.

To detect damage to the underground pipeline, a mathematical model, allowing to take into account the most significant Factors affecting the distribution of temperature on the day surface. To implement this model, a software package has been developed and results of numerical calculations. With the help of these calculations, in particular, It is established that modern thermal imaging equipment has a principal possibility to determine an unauthorized frame in the main pipeline at a depth of two meters in clay soil.

This paper assists in understanding contesting technological capabilities and doctrinal modification between India and Pakistan that are drifting South Asia towards instability, leaving the nuclear deterrence in a dark abyss. Hawks on both sides of the nuclear armed rivals are unprecedentedly chanting threats of nuclear war. More bothersome is the indications of shifting the Indian policy of No First Use (NFU), calls for doctrinal modifications and counterforce temptations. An Indian quest for escalation dominance and Pakistani quest for stability against India is in fact a mutual struggle beyond ‘minimum credible’ to ‘assured second strike’ capabilities.
