Role of Steroids in COPD
Vishnu Sharma
Online Journal of Health & Allied Sciences , 2002,
Abstract: There has been a lot of debate regarding the role of steroids in the management of Chronic Obstructive Pulmonary Disease. Now with a better understanding of the pathophysiology of COPD, the role of steroids in the management of COPD has become clearer.
PERFORMANCE ANALYSIS OF ROUND ROBIN SCHEDULING USING ADAPTIVE APPROACH BASED ON SMART TIME SLICE AND COMPARISON WITH SRR
Vishnu Kumar Dhakad,Lokesh Sharma
International Journal of Advances in Engineering and Technology , 2012,
Abstract: The Time Sharing System is more multifaceted about the performance and calculating the average waiting time, turnaround time, response time, and context switches from the number of processes mainly depends on the CPU scheduling algorithm where the CPU is one of the most important computer resource and as round robin scheduling is considered most widely used scheduling algorithms. The Round Robin Scheduling Algorithm has disadvantage is longer average waiting time, higher context switches, higher turnaround time and low throughput. In this research a new proposed algorithm called Adaptive Round Robin Scheduling Algorithm is presented which is discussed here. The new proposed algorithm called “Adaptive Round Robin (ARR) Scheduling a Novel Approach Based on Shortest Burst Time Using Smart Time Slice”. It is a Priority Driven Scheduling Algorithm based on burst time of processes. It is also uses fixed time quantum same as Simple RR but calculation of time quantum is another factor here. First of all we arrange the processes according to the execution time/burst time in increasing order that is smallest the burst time higher the priority of the running process. The next idea of this approach is to choose the Smart Time Slice (STC) is mainly depends on number of processes. The Smart Time Slice is equal to the mid process burst time of all CPU burst time when number of process given odd. If number of process given even then we choose the time quantum according to the average CPU burst of all running processes. The use of scheduling algorithm increased the performance and stability of the time sharing systems and support building of an self-adaptation operating system, which means that the system is who will adapt itself to the requirements of the user and vice versa.
Management of Tuberculosis- The Need to Enforce Proper Treatment Guidelines among Private Practitioners in India.
Vishnu Sharma M,Anupama N
Online Journal of Health & Allied Sciences , 2012,
Abstract: Tuberculosis continues to be a daunting challenge for our healthcare system. Even after fifteen years of the much publicised Revised National Tuberculosis Control Programme that envisages directly observed short course chemotherapy (DOTS), TB continues to spread and drug resistant strains, MDR and XDR, are also increasingly reported. More than 50% of TB patients seeking private health care, but the level of awareness regarding treatment of TB among private practitioners appears to be poor. All this call for an urgent revamp of TB control strategy in India.
Evolution of Weak Shocks in One Dimensional Planar and Non-planar Gasdynamic Flows
Vishnu D. Sharma,Raghavendra Venkatraman
Physics , 2011, DOI: 10.1016/j.ijnonlinmec.2012.06.001
Abstract: Asymptotic decay laws for planar and nonplanar shock waves and the first order associated discontinuities that catch up with the shock from behind are obtained using four different approximation methods. The singular surface theory is used to derive a pair of transport equations for the shock strength and the associated first order discontinuity, which represents the effect of precursor disturbances that overtake the shock from behind. The asymptotic behaviour of both the discontinuities is completely analysed. It is noticed that the decay of a first order discontinuity is much faster than the decay of the shock; indeed, if the amplitude of the accompanying discontinuity is small then the shock decays faster as compared to the case when the amplitude of the first order discontinuity is finite (not necessarily small). It is shown that for a weak shock, the precursor disturbance evolves like an acceleration wave at the leading order. We show that the asymptotic decay laws for weak shocks and the accompanying first order discontinuity are exactly the ones obtained by using the theory of nonlinear geometrical optics, the theory of simple waves using Riemann invariants, and the theory of relatively undistorted waves. It follows that the relatively undistorted wave approximation is a consequence of the simple wave formalism using Riemann invariants.
Weighted Approximation theorem for Choldowsky generalization of the q-Favard-Szász operators
Preeti Sharma,Vishnu Narayan Mishra
Mathematics , 2015,
Abstract: We study the convergence of these operators in a weighted space of functions on a positive semi-axis and estimate the approximation by using a new type of weighted modulus of continuity and error estimation.

Preeti Sharma,Vishnu Narayan Mishra
Mathematics , 2015,
Abstract: The present paper deals with the Stancu type generalization of the Kantorovich discrete $q$-Beta operators. We establish some direct results, which include the asymptotic formula and error estimation in terms of the modulus of continuity and weighted approximation.
On approximation properties of Baskakov-Schurer-Szasz operators
Vishnu Narayan Mishra,Preeti Sharma
Mathematics , 2015,
Abstract: In this paper, we are dealing with a new type of Baskakov-Schurer-Szasz operators (\ref{eq1}). Approximation properties of this operators are explored: the rate of convergence in terms of the usual moduli of smoothness is given, the convergence in certain weighted spaces is investigated. We study $q$-analogues of Baskakov-Schurer-Sz\'{a}sz operators and it's Stancu generalization. In the last section, we give better error estimations for the operators (\ref{eq2}) using King type approach and obtained weighted statistical approximation properties for operator (\ref{qb})
Distribution and Prevalence of Dermatophytes in Semi-Arid Region of India  [PDF]
Vishnu Sharma, Tarun Kumar Kumawat, Anima Sharma, Ruchi Seth, Subhash Chandra
Advances in Microbiology (AiM) , 2015, DOI: 10.4236/aim.2015.52010
Abstract: Earth has been documented as a natural territory for fungi which cover individual kingdom with evolution. In subsequently vertebrates developed keratin which was a part of life as a structural aspect. Few moulds have skilled to digest keratin and crop up from soil and wastewater habitats. They take part as a keratinolytic agent in the purification of α-keratins with an incidence of disulphide and hydrogen bonds which are improperly biodegradable. The best moulds genera to decay of keratin are Microsporum, Trichophyton and Epidermophyton. The presences of these genera are open health issues in developing countries where they cause the mortal mycotic contagion. The reason behind this is perceived to be the poor hygienic environment and socioeconomic behaviour among people. The present review is a compilation of updated information concerning the nature of these keratinolytic moulds and abundances of most contributed developing countries including India.

Agent based Congestion Control Performance in Mobile ad-hoc Network:A Survey paper
Vishnu Kumar Sharma,Dr. Sarita Singh Bhadauria
International Journal of Advanced Computer Sciences and Applications , 2011,
Abstract: A Congestion control is a key problem in mobile ad-hoc networks. The standard TCP congestion control mechanism is not able to handle the special properties of a shared wireless channel. Many approaches have been proposed to overcome these difficulties. ideas and show their interrelations. mobile agent based congestion control Technique routing is proposed to avoid congestion in ad hoc network. Some mobile agents are added in ad hoc network, which carry routing information and nodes congestion status. When mobile agent travels through the network, it can select a less-loaded neighbor node as its next hop and update the routing table according to the node’s congestion status. With the aid of mobile agents, the nodes can get the dynamic network topology in time. In this paper, we give an overview over existing proposals, explain their key ideas, TCP Issues, Reduce the Congestion, delay in mobile ad-hoc network and proposed solution.
