Rats were divided into four groups of 6 each for both tests....
Gardenia latifolia (Rubiaceae) is commonly known as Indian boxwood or Ceylon boxwood, is a densely foliaceous small tree that occurs throughout the greater parts of Indian common in deciduous forests along the streams. The stem bark and fruits are reported to be used in the treatment of various ailments such as snake bite, skin diseases, stomach pa...
In this paper, we present a conceptual framework for modelling clustered natural hazards that makes
use of historical event data as a starting point. We review a methodology for modelling clustered
natural hazard processes called Poisson mixtures. This methodology is suited to the application
we have in mind as it naturally models processes that yi...
Probabilistic risk assessment systems for tropical cyclone hazards rely on large ensembles of model simulations to characterize cyclones tracks, intensities, and the extent of the associated damaging winds. Given the computational costs, the wind field is often modeled using parametric formulations that make assumptions that are based on observatio...
In this paper, we present a novel framework for modelling clustering in natural hazard risk models. The framework we present is founded on physical principles where large-scale oscillations in the physical system is the source of non-Poissonian (clustered) frequency behaviour. We focus on a particular mathematical implementation of the "Super-Clust...

Cancer is a category of diseases characterized by out-of-control cell growth. There are various types of cancer, and each is classify by the type of cell that is primarily affected. Cancer is a circumstance which arises while a cell starts disobeying the check mechanisms, which control the rate of cell proliferation and starts dividing in an uncont...
The Western North Pacific (WNP) is the most active basin in terms of
tropical cyclone and typhoon occurrences. The densely populated
countries that form the western boundary of WNP basin -- e.g. China,
Japan and the Philippines -- are exposed to extreme wind gusts, storm
surge and fresh water flooding eventually triggered by Tropical Cyclones
(TC)...

This paper investigates the modelling of over-ocean hurricane surface wind fields and their associated uncertainty. The wind models tested include parameterized balance models, a two-dimensional numerical planetary boundary-layer model and a three-dimensional (3D) linear analytical boundary-layer model. Using a set of archived over-ocean surface wi...
Cod liver oil is used widely as a dietary supplement. The present study was carried out to evaluate the effect of cod liver oil (0.5 g/kg, p.o. and 1 g/kg, p.o.) on gastric and duodenal ulcers.
The study was carried out on different gastric ulcer models such as acetic acid induced chronic gastric ulcers, pylorus ligation, indomethacin induced ulcer...
RMS produces software that a large part of the insurance industry uses to set insurance rates in hurricane-prone regions in the US. An important input to our product is the expected number of annually averaged hurricanes making landfall over the next five years. Our approach to the hurricane number prediction has two steps. First, we build a large...
So far no study seems to be available for the scattering of fast positrons by sodium and potassium atoms. Since these alkali atoms have high values of the dipole polarizability it is expected that polarization and absorption effects will play an important role in the scattering process. Hence, for these targets even in the intermediate energy range...
A model complex potential is employed to obtain integrated elastic cross sections, absorption cross sections, and total cross sections for positron scattering from argon atoms in 100--800 eV energy range. The total cross sections are found to be in good agreement with the experimental data for E> or =300 eV and lower than the corresponding electron...
Differential and total elastic cross sections for the elastic scattering of electrons and positrons by calcium atoms in the intermediate energy regions 10-500 eV and 10-75 eV, respectively, are evaluated using a real optical potential and are compared with available theoretical results.

A method suggested by Das is modified and applied to the elastic scattering of electrons and positrons by the hydrogen atom in the intermediate-energy range varying from 50 eV to 1 keV. It is shown that the modification has removed, to a great extent, some of the deficiencies of the method suggested by Das.

By following the semi-empirical approach of Khare and Kumar (1980) for ionization cross-section per unit energy range, the mean energy expended per ion pair due to proton impact on molecular nitrogen and oxygen of uniform density has been calculated using the continuous slowing down approximation. The values so obtained are practically constant for...
Semi-empirical relations are employed to obtain differential and total ionization cross-sections due to proton impact on ammonia and methane. Peaks appearing in the experimental cross-sections are explained as being due to the Auger process. The results thus obtained are in good agreement with the available experimental data (within 12% for ammonia...
