Diagnosis of superficial mycoses by direct microscopy - A statistical evaluation
Mohanty J,Mohanty S,Sahoo R,Sahoo A
Indian Journal of Dermatology, Venereology and Leprology , 1999,
Abstract: A mycological study was undertaken in 250 cases of superficial mycotic infections, which included 210 cases of dermatophytosis, 18 cases of cutaneous candidiasis and 22 cases of tinea versicolor. The scrapings from all the cases were subjected to direct microscopic examination in 10% KOH solution and culture was done in case of candidiasis and dermatophytosis. Out of 250 cases direct microscopy was positive (KOH +ve) in 88 cases of dermatophytosis, 11 cases of candidiasis and all cases of tinea versicolor. Culture for dermatophytes and candida species in SDA medium were positive in 76 and 9 cases respectively. The diagnostic sensitivity, specificity, positive predictive value, negative predictive value and the overall efficiency of the direct microscopy in the diagnosis of superficial mycotic infections were calculated to be 89.41%, 83.90%, 76.76%, 93.02% and 85.96% respectively.
Characterisation of Gliclazide-PEG 8000 Solid Dispersions
S Biswal, J Sahoo, PN Murthy
Tropical Journal of Pharmaceutical Research , 2009,
Abstract: Purpose: The aim of the present study was to characterise gliclazide solid dispersions (SDs) prepared with polyethylene glycol (PEG) 8000 and compare them with SDs in PEG 6000. Methods: Gliclazide SDs containing varying concentrations of PEG 8000 were prepared using the fusion – solvent technique, and their phase solubility behavior and dissolution in 0.1N HCl were assessed at 37 oC. The physical state of, and gliclazide-PEG interactions in, SDs and physical mixtures prepared in ratios of 1:1, 1:2 and 1:5 (gliclazide: PEG 8000), respectively, were characterized by x-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy and differential scanning calorimetry (DSC). Results: The solubility of gliclazide increased with increasing amount of PEG 8000 in aqueous medium. Gibbs free energy (ΔGο tr) values were all negative, indicating the spontaneous nature of gliclazide solubilisation. Dissolution studies indicated a significant increase in the dissolution of gliclazide when dispersed in PEG 8000. FTIR analysis demonstrated the absence of well-defined gliclazide - PEG 8000 chemical interaction while DSC and XRD studies indicated the amorphous /microcrystalline state of gliclazide in the SDs. Conclusion: In both solid dispersions and physical mixture, PEG 8000 increases the solubility and dissolution rate of gliclazide. The increased dissolution rate of gliclazide may be due to the formation of microcrystals, increased wettability and dispersibility in systems containing PEG 8000.
SIMULATION AND ANALYSIS OF BB84 PROTOCOL BY MODEL CHECKING
J.R. SAHOO,S. SATAPATHY
International Journal of Engineering Science and Technology , 2011,
Abstract: Quantum Cryptography or Quantum key distribution (QKD) is a technique to securely distribute a bit string,among two parties by using laws of quantum mechanics. Its security relies on foundations of quantummechanics, where as classical cryptography relies on difficulty of certain mathematical problems that can not able to provide unconditional security. Progress of research in this field indicates that QKD will be available outside the laboratory within next few years. These devices have now become complex and more effort isneeded for their verification. In this paper, we will use the PRISM tool to analyze the security of BB84 protocol and more specifically the property of eavesdropping detection by combining the parameters of quantum channel and power of eavesdropper.

It was found that modular below kneeprosthesis was superior in terms of ease of fabrication,shorter hospital stay, less expensive, stable andcomfortable as compared to the laminated below kneeprosthesis
Polyphonic Music Generation by Modeling Temporal Dependencies Using a RNN-DBN
Kratarth Goel,Raunaq Vohra,J. K. Sahoo
Computer Science , 2014, DOI: 10.1007/978-3-319-11179-7_28
Abstract: In this paper, we propose a generic technique to model temporal dependencies and sequences using a combination of a recurrent neural network and a Deep Belief Network. Our technique, RNN-DBN, is an amalgamation of the memory state of the RNN that allows it to provide temporal information and a multi-layer DBN that helps in high level representation of the data. This makes RNN-DBNs ideal for sequence generation. Further, the use of a DBN in conjunction with the RNN makes this model capable of significantly more complex data representation than an RBM. We apply this technique to the task of polyphonic music generation.
Determining the Possibilities and Certainties in Network Participation for MANETS
Anoop J. Sahoo,Md. Amir Khusru Akhtar
Computer Science , 2014,
Abstract: A mobile ad hoc network is a self organized cooperative network that works without any permanent infrastructure. This infrastructure less design makes it complex compared to other wireless networks. Lot of attacks and misbehavior obstruct the growth and implementation. The majority of attacks and misbehavior can be handled by existing protocols. But these protocols reduce the total strength of nodes in a network because they isolate nodes from network participation having lesser reputation value. To cope with this problem we have presented the Possibility and Certainty model. This model uses reputation value to determine the possibilities and certainties in network participation. The proposed model classifies nodes into three classes such as certain or HIGH grade possible or MED grade and not possible or LOW grade. Choosing HIGH grade nodes in network activities improves the Packet Delivery Ratio which enhances the throughput of the MANET. On the other hand when node strength is poor we choose MED grade nodes for network activities. Thus the proposed model allows communication in the worst scenario with the possibility of success. It protects a network from misbehavior by isolating LOW grade nodes from routing paths.

Sahoo J K,Vatve M,Sahoo K D,Patil V V
Pravara Medical Review , 2010,
Abstract: Evaluation of cardiovascular autonomic functions before and after four yogasanas viz. “Vajrasana” with “Yogamudra”, “Paschimmotanasana”, “Dwipad sahajhasta Bhujangasana”, “Padmasana Yogasana” was carried out. Seventy healthy adults (30 males and 40 females) in the age group of 16-20years were studied. They were trained for 15 days by a certified yoga teacher. Autonomic function tests were carried out before and after 2 and 4 months of yoga practice. Resting heart rate (HR), BloodPressure (BP), heart rate and blood pressure response to standing, deep breathing and valsalva maneuver and pressure response to cold pressor test were studied. A statisticaly significant decrease in resting heart rate, systolic blood pressure after 2 and 4 months of yoga training in both males and females was found. There was also statistical significant increase in heart response to deep breathing (E:I ratio) from 1.4 (mean) to 1.56 in males and 1.4 to 1.49 in females. Valsalva ratio also increased from 1.09 to 1.17 in males and 1.09 to 1.21 in females after 4 months training. Our results indicate that the effects of these asanas is to increase vagal modulation of R:R intervals and reduce sympathovagal balance. However, the study is limited by the facts that it is not controlled.

Pal A, Behera J, Sahoo J, Swain T and Sahu PK
International Journal of Pharmaceuticals Analysis , 2010,
Abstract: Epilepsy is a neurological disorder. About 0.5%-1% of world population is affected by epilepsy.Petit mal epilepsy is the main seizure type in 15-20% of epileptic children. The mainstream intervention forpetit mal epilepsy is T-type Ca ++ channel blocker like ethosuximide. However, there is a need for safer andeffective drug. The protein-ligand interaction plays a significant role in structure based drug designing. In thepresent work we have taken t-type calcium channel as the target and identified natural compounds that canbe used against petit mal epilepsy. Here the drug ethosuximide is used as standard (E value = -132.35).Twelve natural compounds are retrieved from PubMed and are checked for drug likeness with bioinformaticstool ADMETox to satisfy Lipinski’s rule of five. Ten natural drugs qualify this step and are docked withreceptor using HEX docking software. All the compounds taken for docking were found to be better than theconventional drug, Ethosuximide.
A Finite Element Study of Elastic-Plastic Hemispherical Contact Behavior against a Rigid Flat under Varying Modulus of Elasticity and Sphere Radius  [PDF]
Prasanta Sahoo, Biplab Chatterjee
Engineering (ENG) , 2010, DOI: 10.4236/eng.2010.24030
Abstract: The present study considers a finite element analysis of elastic-plastic axi-symmetric hemispherical contact for a frictionless deformable sphere pressed by a rigid flat. The material of the sphere is modeled as elastic perfectly plastic. Analysis is carried out to study the effect of varying modulus of elasticity and sphere radius in wide range of dimensionless interference until the inception of plasticity as well as in plastic range. Results are compared with previous elastic-plastic models. It is found that materials with Young’s modulus to yield strength (E/Y) ratio less than and greater than 300 show strikingly different contact phenomena. The dependency of E on dimensionless interference at which the plastic region fully covers the surface is observed. However with different radius, finite element study exhibits similar elastic-plastic phenomena.
Physicochemical and Biochemical Reclamation of Soil through Secondary Succession  [PDF]
Kamala Haripal, Sunanda Sahoo
Open Journal of Soil Science (OJSS) , 2013, DOI: 10.4236/ojss.2013.35028
Abstract:

Conversion of forest to agricultural fields has become a common practice in India. Very often these fields have been abandoned due to lack of sustainable production. In course of time these fallow lands undergo natural secondary succession. Present study was carried out to find out the restoration of soil physicochemical and biochemical properties in a chronosequence of 2 yr, 4 yr, 6 yr, 11 yr, and 15 yr fallow lands. Soil enzyme activities play key roles in the biochemical functioning of soils, including soil organic matter formation and degradation, nutrient cycling, and reflect the change in soil management and land use. There was gradual improvement in the physical condition and nutrient status along with increase in soil amylase, cellulase, dehydrogenase, phophatase, and urease activity in the present study with the progress of fallow age which indicates the importance of natural secondary succession in soil restoration. However the PCA analysis indicated that natural vegetational succession could reclaim the soil quality and promote ecosystem restoration but it required a long time under the present local climatic condition.
