Non-syndrome multiple supplemental supernumerary teeth
Kalra N,Chaudhary S,Sanghi S
Journal of the Indian Society of Pedodontics and Preventive Dentistry , 2005,
Abstract: Multiple supernumerary teeth without any associated systemic conditions or syndromes are not common. We document a case of non-syndrome multiple supplemental supernumerary teeth in mandibular premolar region of an adolescent male patient, an incidental findings during routine radiographic examination. Periodic examination is recommended to monitor the clinical behavior.
Improved G-3PAKE Protocol with Formal Verification
Manju Sanghi
International Journal of Information and Network Security (IJINS) , 2012, DOI: 10.11591/ijins.v1i1.249
Abstract: In 2007, Lu and Cao proposed a simple three party password authenticated key exchange (S-3PAKE) protocol. In 2008, Guo et al. have shown that S-3PAKE protocol is completely insecure against man-in-the-middle attack and undetectable on-line password guessing attack. They also provided an improved protocol (G-3PAKE) that addresses the identified security problems. Recently, Choi and Yoon have demonstrated that G-3PAKE protocol still falls prey to undetectable on-line password guessing attack by any other client. In the present paper we propose an improved G-3PAKE protocol which can resist all the known attacks along with its formal proof.
Enzymatic Formation of Gold Nanoparticles Using Phanerochaete Chrysosporium  [PDF]
Rashmi Sanghi, Preeti Verma, Sadhna Puri
Advances in Chemical Engineering and Science (ACES) , 2011, DOI: 10.4236/aces.2011.13023
Abstract: When fungus Phanerochaete chrysosporium was challenged with gold ions under ambient aqueous conditions gold nanoparticles were formed within 90 minutes. Controlling experimental conditions like the age of fungus, incubation temperature and different concentration of gold chloride solution had drastic effect on the morphology of the nanoparticles formed. The enzyme assays indicated the role of enzyme as a reducing and shape directing agent. Laccase was the dominating enzyme in the case of fungal media for the synthesis of extracellular gold nanoparticles. Ligninase was responsible for the intracellular formation of nanoparticles on the fungal mycelium. The stabilization of the nanoparticles (NPs) via protein layer was evident by Atomic Force Microscopy (AFM) which revealed the nanoparticles to be spherical in the range of 10-100 nm. This study represents an important advancement in the use of fungal enzymes for the biosynthesis of highly stable gold nanoparticles by a green and mild technique in one pot in aqueous media.
Nutritional Factors and Osteoarthritis: A Review Article
Ms. Divya Sanghi,Dr. Sachin Avasthi,Prof. R N Srivastava,Dr. Ajai Singh
Internet Journal of Medical Update - EJOURNAL , 2009,
Abstract: Osteoarthritis (OA) is the most common disease according to TNS Arogya survey 2007. Although OA was previously thought to be a progressive degenerative disorder, it is now known that spontaneous arrest or reversal of disease can occur. Conventional medications are often effective for symptomatic relief but they can also cause significant side effects and do not slow the progression of disease. Though the role of nutritional factors in OA has been suggested as early as 700 BC, it was first established in the 1960s. Several nutritional factors are helpful in relieving the symptoms of OA and they might positively affect the progression of the disease without any side effects. Preliminary evidences suggest several of these may have a role in influencing the course of OA. Studies have proven the role of these factors and experiment based results have established their therapeutic role. Research is ongoing on the beneficial properties of plant derived extracts for OA and nutraceuticals industries are accordingly making firm contribution to this sector. This article focuses the role of nutrients to slow down the progression of OA and their future aspects.

A Case of Atrial Fibrillation from Cyclosporine Toxicity
Pramod Sanghi,Masood Ahmad
Indian Pacing and Electrophysiology Journal , 2004,
Abstract: We describe the unusual occurrence of atrial fibrillation immediately after a seizure in a young patient with cyclosporine toxicity. The new onset atrial fibrillation was triggered by high levels of cyclosporine and possibly facilitated by the electrolyte imbalances post seizure and the presence of underlying mild left atrial enlargement.
A Conservative Pressure-Correction Method on Collocated Grid for Low Mach Number Flows  [PDF]
S. M. Yahya, S. F. Anwer, S. Sanghi
World Journal of Mechanics (WJM) , 2012, DOI: 10.4236/wjm.2012.25031
Abstract: A novel extension to SMAC scheme is proposed for variable density flows under low Mach number approximation. The algorithm is based on a predictor—corrector time integration scheme that employs a projection method for the momentum equation. A constant-coefficient Poisson equation is solved for the pressure following both the predictor and corrector steps to satisfy the continuity equation at each time step. The proposed algorithm has second order centrally differenced convective fluxes with upwinding based on Cell Peclet number while diffusive flux are viscous fourth order accurate. Spatial discretization is performed on a collocated grid system that offers computational simplicity and straight forward extension to curvilinear coordinate systems. The algorithm is kinetic energy preserving. Further in this paper robustness and accuracy are demonstrated by performing test on channel flow with non-Boussinesq condition on different temperature ratios.
Public key cryptosystem and a key exchange protocol using tools of non-abelian group
H. K. Pathak,,M. Sanghi
International Journal on Computer Science and Engineering , 2010,
Abstract: Public Key Cryptosystems assure privacy as well as integrity of the transactions between two parties. The sizes of the keys play an important role. The larger the key the harder is to crack a block ofencrypted data. We propose a new public key cryptosystem and a Key Exchange Protocol based on the generalization of discrete logarithm problem using Non-abelian group of block upper triangular matrices of higher order. The proposed cryptosystem is efficient in producing keys of large sizes without the need of large primes. The security of both the systems relies on the difficulty of discrete logarithms over finite fields.
