Alcoholism – the Worst Addiction

Introduction: The most common substance of abuse/dependence in patients presenting for treatment in western countries is alcohol. Ethyl alcohol or ethanol which is also called medicinal alcohol is used as an official drug compendium. It is also administered as an antidote in methanol poisoning. However, regular consumption of high amounts of alcoholic drinks induces dependence and addiction lea...

Covid 19: The Worst Health Calamity Of The World

The world has experienced an increased incidence and transboundary spread of emerging infectious diseases due to population growth, urbanization and globalization over the past four decades. Most of these newly emerging and re-emerging pathogens are viruses. On an average, more than two new species of viruses infecting humans are reported worldwide every year most of which are likely to be RNA ...

Inversion Assuming Weak Scattering

The study of weak scattering from inhomogeneous media or interface roughness has long been of interest in sonar applications. In an acoustic backscattering model of a stationary field of volume inhomogeneities, a stochastic description of the field is more useful than a deterministic description due to the complex nature of the field. A method based on linear inversion is employed to infer info...

Polynomials Assuming Square Values

If f(x1, ..., xn) ∈ Z[x1, ..., xn] has the property that every integer specialization gives an integral square value, then f is itself the square of a polynomial. We also give an effective version of this result by using an effective version of a classical theorem of E. Noether along with a theorem of Lang and Weil.
