Peha-haft bandage as a new dressing for pediatric hypospadias repair
Gangopadhyay A,Sharma S
Indian Journal of Plastic Surgery , 2005,
Abstract: Hypospadias Repair has varied alternatives in every step including dressing. Objective: To compare Peha-Haft cohesive dressing with compressed gauze penile wrap dressing in hypospadias repair. Patients and methods: Peha-Haft cohesive dressing was prospectively used in 60 subjects (Group A) over a period of three and a half years from Jan.2001 to July 2004 and compared with 60 subjects of compressed gauze dressing with micropore adhesive (Group B). Primary outcome measures were ease of application, cost, comfort with dressing, dressing related early complications, pain during dressing removal assessed by FLACC score and time taken during removal. Results: Time taken during dressing removal was 30 + 11 seconds in Group A and 180 + 26 seconds in Group B. FLACC score was 3 + 2 in Group A and 7 + 3 in Group B. No sedation was required in the Group A while it was required in 26 cases in Group B Conclusion: Peha-Haft dressing was superior in terms of the ease of application, cost, comfort with dressing, dressing related early complications, time consumed and pain during dressing removal.
Assessment of Irrigation Potential of Groundwater using Water Quality Index Tool
K. Adhikari,B. Chakraborty,A. Gangopadhyay
Environmental Research Journal , 2012, DOI: 10.3923/erj.2012.197.205
Abstract: Transforming parametric concentrations into qualitative scores irrespective of unit has made the WQI a comprehensive and easy to use tool to the decision makers. As criteria of water quality vary with purpose of use of the groundwater, selection of water quality parameters, involved in working out quality index for specific use also differs. Use of Groundwater Quality Index (GWQI) technique to assess irrigation water quality is innovative in this study. Electrical Conductivity (EC), Sodium Adsorption Ratio (SAR) and Residual Sodium Carbonate (RSC), judged as the three most important parameters to designate irrigation quality of groundwater have been used to work out GWQI in this study. Preparation of ISO Index maps using water quality scores, derived through GWQI tool, vividly portray the irrigation water quality status of the study area where most of the area fall under excellent and good categories. The marked difference in water quality with respect to season in some areas of Southeastern and Southwestern parts of the study area may be correlatable to the recharge and discharge zones of groundwater, respectively.
Probing the Leggett-Garg Inequality for Oscillating Neutral Kaons and Neutrinos
Gangopadhyay, D.;Home, D.;Roy, A. Sinha
High Energy Physics - Phenomenology , 2013,
Abstract: The Leggett-Garg inequality (LGI) as a temporal analogue of Bell's inequality, derived using the notion of realism, is applied in a hitherto unexplored context involving the weak interaction induced two-state oscillations of decaying neutral kaons and neutrinos. The maximum violation of LGI obtained from the quantum mechanical results is significantly higher for the oscillating neutrinos compared to that for the kaons. Interestingly, the effect of CP non-invariance for the kaon oscillation is to enhance this violation while, for neutrinos, it is sensitive to the value of the mixing parameter.

Quality Traps in Localized Competition
Partha Gangopadhyay,Mustafa A Rahman,Nasser Elkanj
Modern Applied Science , 2011, DOI: 10.5539/mas.v5n5p3
Abstract: A wide spectrum of technologies, producing a vast array of product qualities, coexists in modern markets today. Many of these markets are also characterised by what is commonly known as localized competition that refers to a special industrial structure in which different firms compete directly with different groups of rivals. We explore the endogenous choice of product quality in localized competition such that the choice of product quality by a seller has effects only on those rivals who share the common market segment. In the proposed model multiple equilibria may occur and the present analysis may be seen as a rationalization for the idea that a market segment may become trapped in a “low-quality” equilibrium. In the presence of multiple equilibria and the quality trap, the industrial policy may have a welfare-enhancing role in coordinating expectations. We then extend the model to highlight the conditions that can preclude the possibility of the quality trap in localised competition.
Chondroid lipoma in a child
Patne Shashikant,Aryya N,Gangopadhyay A
Indian Journal of Pathology and Microbiology , 2008,
Abstract: Chondroid lipoma (CL), a rare lipoma variant, has not been described well for patients younger than 14 years of age. We herein report an extremely unusual instance of CL in a 7-year-old child. The cut surface of the tumor showed peculiar tan-brown and yellow-white areas. Histopathological sections showed the presence of eosinophilic variably vacuolated round- to oval-spindle cells in a myxo-hyaline background. The findings were consistent with CL. The case is reported because of its extreme rarity.
Onlay free preputial graft for mid and distal penile hypospadias
Gangopadhyay A,Sharma Shilpa,Mongha Ritesh
Journal of Indian Association of Pediatric Surgeons , 2005,
Abstract: Tubularized free preputial graft for hypospadias repair had been tried in the past and discarded due to high incidence of graft shrinkage causing stricture formation. We have tried to revive the technique using onlay method thus avoiding stricture formation. The technique was used in 33 subjects (Group A) and compared with 33 subjects in control group (Group B) in whom other techniques of urethroplasty were used. The study was a randomized controlled trial. The mean length of the free preputial graft was 22.06 + 4.68 mm (16-35 mm) and breadth was 9.0 + 1.32 mm (7-11 mm). Fistulae developed in 3 patients in group A out of which one healed spontaneously. In group B, 6 patients had fistula formation. Complications developed in 18% cases in group A and 50% cases in group B. There was significant difference between the cosmetic results (p < 0.05) with 58% excellent results in group A and 27% in group B. Free preputial graft onlay urethroplasty has better functional and cosmetic results.
Plasmonic Induced Potential in Metal-Semiconductor Composits
Shiva Shahin,Palash Gangopadhyay,Robert A. Norwood
Physics , 2015,
Abstract: We utilize experimental tools such as conductive atomic force microscopy and electrostatic force microscopy on photo-excited arrays of gold nanoparticles on indium tin oxide substrate. The nanoparticles are partially covered by a thin semiconductor polymer. The change in the current and potential profiles of the composite metal-semiconductor sample after excitation at plasmonic resonance frequency of metallic nanoparticles is analyzed.
