Fighting Zoonotic, Rabies and Public Health in Colonial India
Rabies is the oldest Zoonotic diseases in the world and one of the most important Zoonotic diseases in India. It was one of the most difficult problems confronted both by the medical and veterinary authorities in colonial India. The disease is transmitted from animal to animal and from animal to man through saliva. More than 90 per cent of cases of human rabies are transmitted by dogs which was a major concern of public health. A few British officials and soldiers were bitten by dogs during the colonial period. As a result, they suffered from rabies. As ownerless dogs were infested all through the country, the disease prevailed largely at that time. Gradually, rabies became a problem to the colonial Government. Louis Pasteur obtained his first success against rabies through vaccination in 1885. At that time, Dr. Lingard, Bacteriologist, had proposed to introduce a system of anti-rabies vaccination in the Bacteriological laboratory at Poona. A similar proposal was also submitted by J.H.B. Hallen, a civil Surgeon in 1890. Later, five institutes were established in India for anti-rabies treatment. Gradually rabies patients were treated at pasture institute. Thus, this paper examines impact of rabies, treatment and veterinary public health policy in colonial India. The great Zoonotic waves of rabies that suffered public health in colonial India are also focus of this paper
The Finslerian quantum cosmology
We present a Friedmann-Robertson-Walker (FRW) quantum cosmological model
within the framework of Finslerian geometry. In this work, we consider a
specific fluid. We obtain the corresponding Wheeler-DeWitt equation as the
usual constraint equation as well as Schr\"odinger equation following Dirac,
although the approaches yields the same equation of time independent equation
for the wave function of the universe. We provide exact classical and quantum
mechanical solutions. We use the eigenfunctions to study the time evolution of
the expectation value of the scale factor. Finally we discuss the physical
meaning of the results.Comment: To appear in Can.J.Phy
Thin Shell Wormhole in Heterotic String Theory
Using 'Cut and Paste' technique, we develop a thin shell wormhole in
heterotic string theory. We determine the surface stresses, which are localized
in the shell, by using Darmois-Israel formalism. The linearized stability of
this thin wormhole is also analyzed.Comment: 12 pages, 2 figures, Accepted in Int. J. Mod. Phys.
Vacuumless topological defects in Lyra geometry
Few years ago, Cho and Vilenkin have proposed that topological defects can
arise in symmetry breaking models without having degenerate vacua. These types
of defects are known as vacuumless defects. In the present work, the
gravitational field of a vacuumless global string and global monopole have been
investigated in the context of Lyra geometry. We find the metric of the
vacuumless global string and global monopole in the weak field approximations.
It has been shown that the vacuumless global string can have repulsive whereas
global monopole exerts attractive gravitational effects on a test particle. It
is dissimilar to the case studied in general relativity.Comment: 14 pages, 9 figures. To appear in Astrophys.Space.Sc
Construction of 3D wormhole supported by phantom energy
In this article, we have found a series solution of 3D Einstein equations
describing a wormhole for an inhomogeneous distribution of phantom energy.
Here, we assume equation of state is linear but highly anistropic.Comment: 9 papge, 4 figures. Accepted for publication in Physica Script
