Simulation of Runoff and Sediment Yield for a Himalayan Watershed Using SWAT Model  [PDF]
Sanjay K. Jain, Jaivir Tyagi, Vishal Singh
Journal of Water Resource and Protection (JWARP) , 2010, DOI: 10.4236/jwarp.2010.23031
Abstract: Watershed is considered to be the ideal unit for management of the natural resources. Extraction of water-shed parameters using Remote Sensing and Geographical Information System (GIS) and use of mathematical models is the current trend for hydrologic evaluation of watersheds. The Soil and Water Assessment Tool (SWAT) having an interface with ArcView GIS software (AVSWAT2000/X) was selected for the estimation of runoff and sediment yield from an area of Suni to Kasol, an intermediate watershed of Satluj river, located in Western Himalayan region. The model was calibrated for the years 1993 & 1994 and validated with the observed runoff and sediment yield for the years 1995, 1996 and 1997. The performance of the model was evaluated using statistical and graphical methods to assess the capability of the model in simulating the run-off and sediment yield from the study area. The coefficient of determination (R2) for the daily and monthly runoff was obtained as 0.53 and 0.90 respectively for the calibration period and 0.33 and 0.62 respectively for the validation period. The R2 value in estimating the daily and monthly sediment yield during calibration was computed as 0.33 and 0.38 respectively. The R2 for daily and monthly sediment yield values for 1995 to 1997 was observed to be 0.26 and 0.47.
Standard operating procedures (SOP) - Back Bone of Pharmaceutical Industries
Sanjay k Jain,Nikhil Bhatwadekar
Pharmaceutical Reviews , 2008,
Abstract: In the face of a challenging regulatory environment, some leading Pharmaceutical companies have found ways to improve quality and costs significantly. To drive this kind of beneficial change, companies must first create a culture where quality objectives are transparent, well understood, and undoubtedly these goals can be achieved by following certain sets of procedures called as “Standard Operating Procedures” (SOP). Procedures are essential for any plant’s effectiveness and efficiency, and they are regulatory requirement in the Pharmaceutical Industry. A typical Pharmaceutical Industry has an average of 1200- 1300 SOPs. A Parenteral Drug Association (PDA) survey found that a typical pharmaceutical company must manage an average of 1250 CGMP-required SOPs and that the average maintenance burden is 15,000 h per firm. A Standard Operating Procedure (SOP) is a set of written instructions that document a routine or repetitive activity which is followed by employees in an organization. The development and use of SOPs are an integral part of a successful quality system. It provides information to perform a job properly, and consistently in order to achieve pre-determined specification and quality end-result.
A Review on Combined Economic and Emission Dispatch using Evolutionary Methods
International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering , 2013,
Abstract: Economic load dispatch is an important optimization problem in power system. Due to the harmful effects of the emission released by fossil fueled electric power plants, Emission Dispatch plays an important role in power industry. This leads to the formulation of combined economic and emission dispatch (CEED) problem. This paper presents a review on evolutionary methods for solving combined economic and emission dispatch problems which mainly include Genetic Algorithm based approach, Particle Swarm Optimization (PSO), Differential Evolution (DE),Strength Pareto Evolutionary Algorithm (SPEA), Artificial Immune System (AIS) which will encourage the researches for providing better solution for CEED optimization in power system.
A Particle Swarm Optimization for Maximum Loadability
International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering , 2013,
Abstract: In this paper, Particle Swarm Optimization (PSO) has been used to find Maximum Loadability on different test power systems. Maximum Loadability Problem is seen as an optimization problem while the power factor of the load is assumed constant. Viability of the proposed method is established and correlated with the well-known method, Continuation Power Flow(CPF), which uses continuation parameterization technique, predictor, corrector steps to draw P-V curve and then to find Maximum Loadability of any system.
A Rare Fatal Case of Internal Hernia Caused by Meckel’s Diverticulum in a Paediatric Patient  [PDF]
Vandana Jain, Sanjay Sahi
Open Journal of Pediatrics (OJPed) , 2011, DOI: 10.4236/ojped.2011.12005
Abstract: We describe a very rare case of an internal hernia associated with a Meckel’s diverticulum, which lead to the death of a young 3 year old boy. The case describes symptoms of abdominal pain and vomiting, on a background of previous intermittent abdominal pain. The possibility of small bowel obstruction was suspected, and appropriate imaging was performed. This case illustrates the need for a high index of suspicion for small bowel obstruction, with appropriate investigations and review. It also highlights the limitations of imaging modalities in identifying complications of Meckel’s diverticulum. It is important to raise awareness of this fatal cause for small bowel obstruction and to help identify suggestive imaging features, which may point towards a possible complicated Meckel’s diverticulum. Earlier recognition and diagnosis could reduce morbidity and mortality.
Role of Mycobacterium tuberculosis pknD in the Pathogenesis of central nervous system tuberculosis
Nicholas A Be, William R Bishai, Sanjay K Jain
BMC Microbiology , 2012, DOI: 10.1186/1471-2180-12-7
Abstract: We screened 398 unique M. tuberculosis mutants in guinea pigs to identify genes required for central nervous system tuberculosis. We found M. tuberculosis pknD (Rv0931c) to be required for central nervous system disease. These findings were central nervous system tissue-specific and were not observed in lung tissues. We demonstrated that pknD is required for invasion of brain endothelia (primary components of the blood-brain barrier protecting the central nervous system), but not macrophages, lung epithelia, or other endothelia. M. tuberculosis pknD encodes a "eukaryotic-like" serine-threonine protein kinase, with a predicted intracellular kinase and an extracellular (sensor) domain. Using confocal microscopy and flow cytometry we demonstrated that the M. tuberculosis PknD sensor is sufficient to trigger invasion of brain endothelia, a process which was neutralized by specific antiserum.Our findings demonstrate a novel in vivo role for M. tuberculosis pknD and represent an important mechanism for bacterial invasion and virulence in central nervous system tuberculosis, a devastating and understudied disease primarily affecting young children.Tuberculosis (TB) of the central nervous system (CNS) is a devastating and often fatal disease, primarily affecting young children. Even when treatment is administered in a timely manner, mortality is extraordinarily high, with surviving patients often experiencing severe neurological sequelae. CNS TB comprises approximately 1% of TB disease worldwide, disproportionately affecting children in developing nations [1]. Coinfection with human immunodeficiency virus increases the likelihood of CNS TB [2,3], and the emergence of drug resistant strains further complicates CNS TB due to limited permeability at the blood-brain barrier (BBB) of several second-line TB drugs. Delays in treatment due to drug-susceptibility testing further reduce the efficacy of available patient care [4].The CNS is protected from the systemic circulation by t
Multisegmental cervical ossification of the posterior longitudinal ligament: Anterior vs posterior approach
Jain Subodh,Salunke Pravin,Vyas K,Behari Sanjay
Neurology India , 2005,
Abstract: Aims : To determine the surgical approach in patients with multisegmental (four or more segments) OPLL of the cervical spine. Methods and Materials : Data of 27 patients who had undergone either an anterior (corpectomy with excision of OPLL and interbody fusion=14 patients) or posterior approach (laminectomy=12, laminoplasty=1 patient) for the multisegmental cervical OPLL was analyzed retrospectively. The patients in each group were statistically similar in respect to preoperative factors such as age, duration of symptoms, preoperative modified Japanese orthopedic association score, OPLL thickness, effective canal diameter, and antero-posterior cord compression ratio. The clinical outcome was assessed by the Harsh grading system and recovery rate was assessed by Hirabayashi method. Results : There was no statistical difference in the outcome, and recovery rate. Nine patients developed complications after anterior approach in contrast to one after posterior approach. Conclusions : In patients with multisegmental cervical OPLL, there was no significant difference in the short-term recovery rate and outcome between two groups. The immediate postoperative complications were less in patients who had undergone posterior approach. From our analysis, it appears that the posterior approach is probably the preferred method of treatment in a multisegmental OPLL in absence of preoperative kyphosis.
Giant pericardial cyst in a 5-year-old child: A rare anomaly
Kumar Sanjay,Jain Promil,Sen Rajeev,Rattan K
Annals of Pediatric Cardiology , 2011,
Abstract: Pericardial cysts are uncommon congenital abnormalities that occur in the middle mediastinum. Most of these are found incidentally on chest x-rays. The occurrence of pericardial cyst in children is quite rare. It needs to be differentiated from other cystic mediastinal masses. A rare case of pericardial cyst in a 5 year old male child is reported. The child presented with chest pain, cough and fever. The preoperative diagnosis of pericardial cyst was suggestive on echocardiography and CT scan. It was confirmed on histopathology after successful surgical excision. The rarity of this benign mediastinal lesion in children prompted us to report this case.

Universal correlations in random matrices: quantum chaos, the $1/r^2$ integrable model, and quantum gravity
Sanjay Jain
Physics , 1996, DOI: 10.1142/S0217732396001223
Abstract: Random matrix theory (RMT) provides a common mathematical formulation of distinct physical questions in three different areas: quantum chaos, the 1-d integrable model with the $1/r^2$ interaction (the Calogero-Sutherland-Moser system), and 2-d quantum gravity. We review the connection of RMT with these areas. We also discuss the method of loop equations for determining correlation functions in RMT, and smoothed global eigenvalue correlators in the 2-matrix model for gaussian orthogonal, unitary and symplectic ensembles.
