Fungal keratitis in Lattice dystrophy
Chatterjee Samrat,Agrawal Deepshikha
Indian Journal of Ophthalmology , 2010,
Abstract: We report a case of fungal keratitis occurring in a patient with lattice dystrophy. A 57-year-old farmer presented with a corneal ulcer following probable entry of paddy husk in the right eye, of one month duration. Corneal scraping revealed pigmented fungal filaments while culture grew Alternaria alternata. Treatment with 5% natamycin eye drops and 1% atropine healed the infection in four weeks. We would like to draw attention to the fact that the cornea in lattice dystrophy is prone to frequent erosions and is a compromised epithelial barrier to invasion by microorganisms. Patients must be made aware of this fact and should seek attention at the earliest following any trivial trauma. Management of minor corneal abrasions in them should be directed at healing the epithelium with adequate lubricants and preventing infection with topical antibiotic prophylaxis.

Malhotra Sumeet,Mandal Partha,Patanker Gopal,Agrawal Deepshikha
Indian Journal of Ophthalmology , 2008,
Abstract: The purpose of this study was to determine clinical presentation, microbiological spectrum and visual outcome of cluster endophthalmitis patients after cataract surgery in central India. The records of cluster endophthalmitis patients were retrospectively reviewed. Three clusters of patients were identified who had undergone vitreous biopsy followed by three-port pars plana vitrectomy with intraocular antibiotics and steroids. Good visual outcome was seen in eight (33%) of 24 patients. Six patients had corneal infiltration. Smear positivity was 58% and culture positivity was 42%. There was significant association ( P < 0.001) between presenting vision of < 20/400 and growth in vitreous culture ( P = 0.006) with poor visual outcome. The association between type of surgery ( P = 0.6), duration of symptoms ( P = 0.64) and corneal infiltration ( P = 0.06) with visual outcome was not significant. Pseudomonas aeruginosa was the organism isolated in vitreous cultures. Thirty three percent patients benefit after appropriate vitreoretinal intervention in cluster endophthalmitis.
Engineering Education in India: Preparation of Professional Engineering Educators  [PDF]
Atasi Mohanty, Deepshikha Dash
Journal of Human Resource and Sustainability Studies (JHRSS) , 2016, DOI: 10.4236/jhrss.2016.42011
Abstract: In 21st century, engineering education in India faces significant challenges as it requires meeting the demands of technical profession and emerging job market. Researchers have found some universally preferred, yet challenging skills for global workforce, e.g., science, technology, engineering and math (STEM), statistics and data analysis skills, are of the topmost priority. Moreover, after being the signatory of Washington Accord, India needs to reinvent not only the India Inc., but also its technical/engineering education system. Recently, we have witnessed a major shift in customer relationship and business strategies of corporate houses. Nowadays, e-learners and online consumers are increasing, for which we have to update our digital world, i.e., infrastructure, content/ domain knowledge, educators/HR trainers. Thus, our technical faculty should need to learn the innovative approaches to teaching and learning, which in turn will require effective professional development for both new and experienced instructors alike. It is high time now to redesign our curricula, pedagogy and make the pre-service teacher preparation programme mandatory part of technical higher education.

Sharma Deepshikha
International Journal of Scientific Research and Reviews , 2013,
Abstract: The best source to get health promoting, green, safe and more effective medicines is “The Nature”.The things which we get from the nature are eco-friendly and less harmful. By using eco-friendlymedicines not only we can protect our skin and body from harmful chemicals but also we can get betterresults. Eco friendly and green medicines are free from toxic chemicals and easily manufactured byextraction of essential oils and waters even at our home also. Essential oils are one of nature’s greatgifts and are found in different parts of the plant such as flowers, leaves and barks or in the rind offruit. For example in rose essential oils are found in flower, in basil and neem it is in the leaves.Essential oils can be used aromatically, topically or taken internally. In present study essential oils areprepared in the laboratory of Chemistry and Environment Department of Jodhpur Institute ofEngineering and Technology, (Co ed.), Jodhpur and used in the manufacturing of green and herbalmedicines.
Development of a Novel Reusable Real Time Monitoring Glucose Sensor Based on Nanostructured Conducting Polyaniline (NSPANI)  [PDF]
Ruchika Chauhan, Deepshikha Saini, Tinku Basu
International Journal of Organic Chemistry (IJOC) , 2013, DOI: 10.4236/ijoc.2013.31010
Abstract: A novel mediatorless reusable glucose biosensor with a remarkable shelf life has been fabricated on electrodeposited film of chemically synthesized nanostructured polyaniline (NSPANI) on indium tin oxide (ITO) coated glass plates using cyclic voltammetry. Glucose oxidase has been covalently immobilized on electrodeposited NSPANI film to fabricate a glucose bioelectrode (GOx/NSPANI-SDS/ITO). The results of linear sweep voltammetry and the high value of heterogeneous rate constant as obtained using Laviron equation indicates that GOx/NSPANI-SDS/ITO bioelectrode can detect glucose in the range of 0.5 to 10.00 mM with high sensitivity of 13.9 μA?mM?1 with a fast response time of 12 seconds. The linear regression analysis of bioelectrode reveals standard deviation and correlation coefficient of 6 μA and 0.994, respectively. The low value of Michaelis-Menten constant (Km) estimated as 0.28 mM using Lineweaver-Burke plot indicates high affinity of glucose oxidase enzyme to glucose and transfer rate. The GOx/NSPANI-SDS/ITO bioelectrode exhibits uniform activity for 12 weeks under refrigerated conditions; however the study is further going on. Attempts have been made to utilize this electrode for estimation of glucose in blood serum and results are found to be within 11% error. The unique features of this novel electrode lie on its reusability, real time monitoring, reproducibility and remarkable shelf life apart from the wide linear range, high sensitivity, low K
Synthesis and characterization of nanocomposites based on polyaniline-gold/graphene nanosheets
Deepshikha Saini,T. Basu
Applied Nanoscience , 2012, DOI: 10.1007/s13204-012-0059-y
Abstract: Polymer nanocomposites (NSPANI/AuNP/GR) based on nanostructured polyaniline, gold nanoparticles (AuNP) and graphene nanosheets (GR) have been synthesized using in situ polymerization. A series of nanocomposites have been synthesized by varying the concentration of GR and chloroauric acid to optimize the formulation with respect to the electrochemical activities. Out of these series of NSPANI/AuNP/GR nanocomposites, it has been found that only one particular nanocomposite has the best electrochemical properties, as analyzed by cyclic voltammetry (CV) and differential pulse voltammetry and conductivity. The best nanocomposite has been characterized by Fourier transform infrared Raman spectroscopy, UV–vis spectroscopy, X-ray diffraction studies, transmission electron microscopy, scanning electron microscopy and atomic force microscopy. The CV of the best nanocomposites show the well-defined reversible redox peaks characteristic of polyaniline, confirming that the polymer maintains its electro activity in the nanocomposites. Another nanocomposite has been prepared with identical composition (as found with the best nanocomposite) by mixing of pre-synthesized nanostructured polyaniline with chloroauric acid and graphene dispersion in order to predict the mechanism of in situ polymerization. It is inferred that the nanocomposite prepared by blending technique loses its property within 48 h indicating phase separation whereas the nanocomposite prepared by in situ technique is highly stable.
Water quality analysis of River Yamuna using water quality index in the national capital territory, India (2000–2009)
Deepshikha Sharma,Arun Kansal
Applied Water Science , 2011, DOI: 10.1007/s13201-011-0011-4
Abstract: River Yamuna, in the national capital territory (NCT), commonly called Delhi (India), has been subjected to immense degradation and pollution due to the huge amount of domestic wastewater entering the river. Despite the persistent efforts in the form of the Yamuna Action Plan phase I and II (YAP) (since 1993 to date), the river quality in NCT has not improved. The restoration of river water quality has been a major challenge to the environmental managers. In the present paper, water quality index (WQI) was estimated for the River Yamuna within the NCT to study the aftereffects of the projects implemented during YAP I and II. The study was directed toward the use of WQI to describe the level of pollution in the river for a period of 10 years (2000–2009). The study also identifies the critical pollutants affecting the river water quality during its course through the city. The indices have been computed for pre-monsoon, monsoon and post-monsoon season at four locations, namely Palla, ODRB, Nizamuddin and Okhla in the river. It was found that the water quality ranged from good to marginal category at Palla and fell under poor category at all other locations. BOD, DO, total and fecal coliforms and free ammonia were found to be critical parameters for the stretch.
Retrieval of dust aerosols during night: improved assessment of long wave dust radiative forcing over Afro-Asian regions
S. Deepshikha,J. Srinivasan
Annales Geophysicae (ANGEO) , 2010,
Abstract: Several investigators in the past have used the radiance depression (with respect to clear-sky infrared radiance), resulting from the presence of mineral dust aerosols in the atmosphere, as an index of dust aerosol load in the atmosphere during local noon. Here, we have used a modified approach to retrieve dust index during night since assessment of diurnal average infrared dust forcing essentially requires information on dust aerosols during night. For this purpose, we used infrared radiance (10.5–12.5 μm), acquired from the METEOSAT-5 satellite (~ 5 km resolution). We found that the "dust index" algorithm, valid for daytime, will no longer hold during the night because dust is then hotter than the theoretical dust-free reference. Hence we followed a "minimum reference" approach instead of a conventional "maximum reference" approach. A detailed analysis suggests that the maximum dust load occurs during the daytime. Over the desert regions of India and Africa, maximum change in dust load is as much as a factor of four between day and night and factor of two variations are commonly observed. By realizing the consequent impact on long wave dust forcing, sensitivity studies were carried out, which indicate that utilizing day time data for estimating the diurnally averaged long-wave dust radiative forcing results in significant errors (as much as 50 to 70%). Annually and regionally averaged long wave dust radiative forcing (which account for the diurnal variation of dust) at the top of the atmosphere over Afro-Asian region is 2.6 ± 1.8 W m 2, which is 30 to 50% lower than those reported earlier. Our studies indicate that neglecting diurnal variation of dust while assessing its radiative impact leads to an overestimation of dust radiative forcing, which in turn result in underestimation of the radiative impact of anthropogenic aerosols.

Mobile SMS Classification: An Application of Text Classification
Deepshikha Patel,Monika Bhatnagar
International Journal of Soft Computing & Engineering , 2011,
Abstract: Text Classification is the process of classifying documents into predefined classes based on its content. Text classification is important in many web applications like document indexing, document organization, spam filtering etc. In this paper we analyze the concept of a new classification model which will classify Mobile SMS into predefined classes such as jokes, shayri, festival etc. All sms are converted into text documents. After preprocessing vector space model is prepared and weight is assigned to each term. In the proposed model we have used entropy term weighting scheme and then PCA is used for reparameterization. Artificial Neural Network is used for classification.
