Book Review: 21 Success Sutras for Leaders by M.S. Rao
(excerpt)
Professor M. S. Rao’s 21 Success Sutras for Leaders (“Success Sutras”) offers keen, managerial insight into the benefits of learning from the experiences of others — whether disadvantageous, banal, or extremely useful. Acclaimed as an international, authoritative resource on leadership, Success Sutras equips the reader with 21 leadership tools and techniques designed to minimize mistakes and maximize leadership effectiveness. Its 22 chapters and 176 pages provide examples and illustrations of international leaders and their respective styles of principled leadership paradigms

Biliary ascariasis from a rural setting: a case study.
Ascariasis is a common helminthic infestation in Malaysia, particularly in rural settings. Ascariasis lumbricoides normally lives in the upper small bowel without causing symptoms. Complications arise when these worms migrate into the bile duct (biliary ascariasis). A case of biliary ascariasis presenting as biliary colic is described. Patient presented with 2 days duration of right upper quandrant pain at the district hospital. Initial investigations were suggestive of acute cholecystitis and patient was treated with empirical antibiotics. However, due to worsening
symptoms, she was transferred to the nearest tertiary setting. The diagnosis of helminthic biliary infestation was established using both ultrasound of the hepatobiliary
system (HBS), CT-Scan abdomen and endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic removal of the worm led to rapid resolution of symptoms and patient was discharged home well
Peculiarities of geological and thermobaric conditions for the gas hydrate deposits occurence in the Black Sea and the prospects for their development
The actuality has been revealed of the necessity to attract the gas hydrate deposits of the Black Sea into industrial development as an alternative to traditional gas fields. This should be preceded by the identification and synthesis of geological and thermobaric peculiarities of their existence. It was noted that the gas hydrates formation occurs under certain thermobaric conditions, with the availability of a gas hydrate-forming agent, which is capable of hydrate formation, as well as a sufficient amount of water necessary to start the crystallization process. The gas hydrate accumulation typically does not occur in free space – in sea water, but in the massif of the sea bed rocks. The important role in the process of natural gas hydrates formation is assigned to thermobaric parameters, as well as to the properties and features of the geological environment, in which, actually, the process of hydrate formation and further hydrate accumulation occurs. It was noted that the source of formation and accumulation of the Black Sea gas hydrates is mainly catagenetic (deep) gas, but diagenetic gas also takes part in the process of gas hydrate deposits formation. The main component of natural gas hydrate deposits is methane and its homologs – ethane, propane, isobutane. The analysis has been made of geological and geophysical data and literature materials devoted to the study of the offshore area and the bottom of the Black Sea, as well as to the identification of gas hydrate deposits. It was established that in the offshore area the gas hydrate deposits with a heterogeneous structure dominate, that is, which comprises a certain proportion of aluminosilicate inclusions. It was noted that the Black Sea bottom sediments, beginning with the depths of 500 – 600 m, are gassy with methane, and a large sea part is favourable for hydrate formation at temperatures of +8...+9ºC and pressures from 7 to 20 MPa at different depths. The characteristics of gas hydrate deposits are provided, as well as requirements and aspects with regard to their industrialization and development. It is recommended to use the method of thermal influence on gas hydrate deposits, since, from an ecological point of view, it is the safest method which does not require additional water resources for its implementation, because water intake is carried out directly from the upper sea layers. A new classification of gas hydrate deposits with a heterogeneous structure has been developed, which is based on the content of rocks inclusions in gas hydrate, the classification feature of which is the amount of heat spent on the dissociation process
KINETIC FEATURES OF THE DISSOCIATION PROCESS OF GAS HYDRATE DEPOSITS
The research is aimed at revealing the theoretical features of the kinetics of the process of
dissociation of natural gas hydrates, the accounting of which is useful in designing technologies for
their development. The process of decomposition of gas hydrates is considered as a heterogeneous
process, proceeding at the interface of the phases and contains three consecutive stages. The
mathematically grounded speed with which molecules fluctuate around fixed positions and the velocity
of their translational motion in the system “gas – rock environment”. The mathematical expression of
the constant coefficient of molecular diffusion is made. It has been established that when gas is
extracted from gas hydrates, external and internal diffusion zones, as well as diffusion inhibition, are
caused, which causes an increase in the decay time of gas hydrate to gas and water. The character of
the dependence of the change in the rate of dissociation during its various periods is revealed. It was
found that the speed of the dissociation process in these conditions varies with the temperature under
the exponential la
Eccentricity content of binary black hole initial data
Using a post-Newtonian diagnostic tool developed by Mora and Will, we examine
numerically generated quasiequilibrium initial data sets that have been used in
recently successful numerical evolutions of binary black holes through plunge,
merger and ringdown. We show that a small but significant orbital eccentricity
is required to match post-Newtonian and quasiequilibrium calculations. If this
proves to be a real eccentricity, it could affect the fine details of the
subsequent numerical evolutions and the predicted gravitational waveforms.Comment: 5 pages, 5 figures, clarifications and minor corrections; version

Ferroelectricity in ultra-thin perovskite films
We report studies of ferroelectricity in ultra-thin perovskite films with
realistic electrodes. The results reveal stable ferroelectric states in thin
films less than 10 \AA thick with polarization normal to the surface. Under
short-circuit boundary conditions, the screening effect of realistic electrodes
and the influence of real metal/oxide interfaces on thin film polarization are
investigated. Our studies indicate that metallic screening from the electrodes
is affected by the difference in work functions at oxide surfaces. We
demonstrate this effect in ferroelectric PbTiO and BaTiO films.Comment: 4 pages in REVTEX4, 4 epsf figure
