Pulmonary Functions in Trained and Untrained Wind Instrument Blowers
Mohan Manohar Sagdeo,,*Prashant Devidas Khuje
People's Journal of Scientific Research , 2012,
Abstract: The present cross-sectional study was designed to ascertain whether regular and trained wind instrument blowers develop higher pulmonary functions than untrained or part time blowers. The study included 155 trained & regular blowers (Group A), 100 untrained part-time blowers (Group B) and 100 non-blowers (Group C). They were investigated by a computerized spirometer (RMS medspiror).Group A subjects showed a significantly higher (p<0.001) percentage predicted value for Forced Vital capacity (FVC), Forced expiratory volume in the 1st second (FEV 1 ), Peak Expiratory Flow Rate (PEFR), Maximum Voluntary Ventilation(MVV), Forced Expiratory Flow at 25% & 50% of FVC (FEF25% & FEF50%), Forced Expiratory Flow between 25% & 75%of FVC (FEF 25-75%), FEF50% of FVC, than the other two groups. However, FEV 1/FVC % in group A was not statistically higher than the other two groups (p=0.3699). Thus, regular training of wind instrument blowing increases the pulmonary functions which may be a physiological advantage of blowing.

Myasthenic crisis-like syndrome due to Cleistanthus collinus poisoning
Damodaram Potikuri,Manohar I,Prabath Kumar D,Mohan Alladi
Indian Journal of Medical Sciences , 2008,
Abstract: Poisoning with Cleistanthus collinus frequently causes cardiac manifestations such as rhythm disturbances and also results in other manifestations such as metabolic acidosis and hypokalemia. We present the case of a patient who presented with a rare myasthenic crisis-like syndrome requiring assisted ventilation due to Cleistanthus collinus poisoning, which responded to treatment with neostigmine.
Intrinsic Half-metallicity in Edge Fluorinated Armchair Boron Nitride Nanoribbons

Physics , 2015,
Abstract: We predict intrinsic half-metallicity in armchair boron nitride nanoribbons (ABNNRs) via edge fluorination. The stability, electronic and magnetic properties of bare and edge fluorinated ABNNRs have been systematically analyzed by means of first-principles calculations within the local spin-density approximation (LSDA). The ribbons whose only edge-B atoms passivated with F atoms (i.e., edge-N atoms are un-passivated), regardless of width, are found half-metallic with a half-metal gap of 0.3 eV. A 100 \% spin polarized charge transport across the Fermi level is expected for such ribbons as the spin polarized states are $\sim$0.4 eV more stable than the spin un-polarized states and only single-spin conducting channels are present across the Fermi level owing to the gigantic spin splitting. The existence of half-metallicity is attributed to the localization of electronic charge at bare edge-N atoms as revealed from the analysis of Bloch states and projected density of states (PDOS).The sufficiently large half-metal gap (0.3 eV) with huge difference in the energies ($\sim$ 0.4 eV) of spin polarized and spin compensated states projects these half-metallic ABNNRs as potential candidate for spintronics applications.
Polaron population controlled of modulation wave vector Manganites
P. R. Sagdeo
Physics , 2009,
Abstract: The growth of charge ordering phenomenon in calcium doped lanthanum manganites La1-xCaxMnO3, x 0.62, 0.67 has been studied using transmission electron microscopy TEM. The diffuse intensity characteristic of short range charge ordering is observed even at room temperature. This diffuse intensity has the local intensity maxima at the incommensurate positions q. With decreasing temperature, the intensity I of super lattice charge ordered spot and the magnitude of its modulation wave vector q increases and there exists a linear relationship between I and q of super lattice charge ordered spot. This linear dependence can be explained taking in to account the population and the columbic interactions between the correlated polarons. It appears that the columbic interactions between the correlated polarons lead to the coherent distributions of eg charge carriers and thereby giving rise to the uniformly periodic superlattice charge ordered state to these manganites.
Epidemiology, clinical manifestations, and diagnosis of chikungunya fever: Lessons learned from the re-emerging epidemic

Indian Journal of Dermatology , 2010,
Abstract: Chikungunya fever, caused by "Chikungunya virus," is an arbovirus disease transmitted by the bite of infected mosquitoes belonging to the genus Aedes. Chikungunya fever epidemics have been reported from several countries around the world. The disease that was silent for nearly 32 years re-emerged in the October 2005 outbreak in India that is still ongoing. The incubation period ranges from 3 to 12 days. The onset is usually abrupt and the acute stage is characterized by sudden onset with high-grade fever, severe arthralgias, myalgias, and skin rash. Swollen tender joints and crippling arthritis are usually evident. In the chronic stage, relapses that include sensation of fever, asthenia, exacerbation of arthralgias, inflammatory polyarthritis, and stiffness may be evident. Neurological, ocular, and mucocutaneous manifestations have also been described. Chronic arthritis may develop in about 15% of the patients. Viral culture is the gold standard for the diagnosis of Chikungunya fever. Reverse transcription polymerase chain reaction and real-time loop-mediated isothermal amplification have also been found to be useful. Serodiagnostic methods for the detection of immunoglobulin M and immunoglobulin G antibodies against Chikungunya virus are more frequently used. Chikungunya is a self-limiting disease; however, severe manifestations such as meningoencephalitis, fulminant hepatitis, and bleeding manifestations may sometimes be life-threatening. Treatment is symptomatic and supportive. Prevention by educating the community and public health officials, vector control measures appear to be the best approach at controlling Chikungunya fever as no commercially available vaccine is available for public use in India for this condition presently.

Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.27114
Abstract: The dielectric properties of pure nematic liquid crystal (BKS/B07) and dye doped (Rhodamine B and Anthraquinone) nematic liquid crystal have been investigated in a wide frequency range of 1 kHz to 10 MHz through the dielectric spectroscopic method at varying temperature. In addition to this optical transmittance and textures of the samples have also been observed with a polarizing microscope.
An Electrothermal Model Based Adaptive Control of Resistance Spot Welding Process  [PDF]
Ziyad Kas, Manohar Das
Intelligent Control and Automation (ICA) , 2015, DOI: 10.4236/ica.2015.62014
Abstract: Resistance Spot Welding (RSW) is a process commonly used for joining a stack of two or three metal sheets at desired spots. The weld is accomplished by holding the metallic workpieces together by applying pressure through the tips of a pair of electrodes and then passing a strong electric current for a short duration. Inconsistent weld and insufficient nugget size are some of the common problems associated with RSW. To overcome these problems, a new adaptive control scheme is proposed in this paper. It is based on an electrothermal dynamical model of the RSW process, and utilizes the principle of adaptive one-step-ahead control. It is basically a tracking controller that adjusts the weld current continuously to make sure that the temperature of the workpieces or the weld nugget tracks a desired reference temperature profile. The proposed control scheme is expected to reduce energy consumption by 5% or more per weld, which can result in significant energy savings for any application requiring a high volume of spot welds. The design steps are discussed in details. Also, results of some simulation studies are presented.

Abstract: The objective of this study is to propose user control system that definitely increases the performance of realtime data service. However the most existing work on this RTDB was based on very critical closed loop control system. To overcome this problem we design a system called user control database model which stimulate theoverload transaction during run time. We also design quality of service scheme and it allows to setting requirements for QOS transaction. The performance of proposed algorithm evaluated in different experiments. So the proposed system will definitely satisfies our needs even critical conditions like overload or run-timeerrors.
