A Comparative Study Of Cultures In The Portrait Of A Lady
Vidya S.Wagh
Indian Streams Research Journal , 2012,
Abstract: For Henry James the prime concern of the novelist is to focus on the real problems of an emerging nation - the problem of national identity. So, he turned to the moral and psychological problems of America and attempted to analyze and project them against the background of Europe. For him his Americans were na ve, innocents confronting a complex and often corrupt established society. So he wanted to examine carefully American's national identity and international role in the late Nineteenth Century – e.g. By his portrait of one young American Lady – “Isabel Archur.”In a word she is too perfect social animal who is connected with every incident and character of the novel. Through the study of her character, the novelist depicts the culture of both countries – America and Europe.
Hepatoprotective activity of Vitex trifolia against carbon tetrachloride-induced hepatic damage
Manjunatha B,Vidya S
Indian Journal of Pharmaceutical Sciences , 2008,
Abstract: Aqueous and ethanol extracts of leaf of Vitex trifolia was investigated for hepatoprotective activity against carbon tetrachloride induced liver damage. To assess the hepatoprotective activity of the extracts, various biochemical parameters viz., total bilirubin, total protein, alanine transaminase, aspartate transaminase and alkaline phosphatase activities were determined. Results of the serum biochemical estimations revealed significant reduction in total bilirubin and serum marker enzymes and increase in total protein in the animals treated with ethanol and aqueous extracts. However significant rise in these serum enzymes and decrease in total protein level was noticed in CCl4 treated group indicating the hepatic damage. The hepatoprotective activity is also supported by histological studies of liver tissue. Histology of the liver tissue treated with ethanol and aqueous extracts showed normal hepatic architecture with few fatty lobules. Hence the present study revealed that Vitex trifolia could afford significant protection against CCl 4 induced hepatocellular injury.
ARP Storm Detection and Prevention Measures
S Vidya,R. Bhaskaran
International Journal of Computer Science Issues , 2011,
Abstract: The Address Resolution Protocol (ARP) is used by computers to map network addresses (IP) to physical addresses (MAC). The protocol has proved to work well under regular circumstances, but it was not designed to cope with malicious hosts. By performing ARP storming attacks, an intruder can create Denial of Service (DoS) in another host and prevent it's functioning or just cause network slowdowns. Several methods to mitigate, detect and prevent these attacks do exist at the router level and through certain customized software tools. In this paper we propose an algorithm to detect the ARP storm at the local sub network level within the ARP boundary in real-time and in offline mode. In real-time, the software detects dynamically, the IPs from which the ARP storm emanates. The inexpensive and portable software developed can be implemented in SOHOs in each machine in the local network. The attempt was successful and also effective in terms of cost, portability and ease of use. The offline packet analysis software, detects all the possible malicious IPs that are responsible for the ARP storm from among the packets captured in real-time using Wireshark. The proposed method also suggests the means of preventing the ARP storm.
Gene Expression Profiling during Wilting in Chickpea Caused by Fusarium oxysporum F. sp. Ciceri  [PDF]
Gayatri S. Gurjar, Ashok P. Giri, Vidya S. Gupta
American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.32023
Abstract: Fusarium oxysporum f. sp. ciceri (Foc), one of the most important fungal pathogen of chickpea, is a constant threat to this crop plant. In the present study gene expression analysis of chickpea roots during Foc infection was performed using various approaches. cDNAs derived from total mRNA during infection process of susceptible (JG62)and resistant (Digvijay) cultivars, were amplified using random oligonucleotides. Sequence characterization of differentially expressed transcripts revealed their homology with many plant genes essential for various metabolic functions including defense. Further, expression patterns of specific candidate gene transcripts were analyzed in the Foc inoculated and uninoculated resistant and susceptible chickpea cultivars, on day 6 of infection. Semiquantitative RT-PCR analysis of defense related genes was performed using gene specific oligonucleotides in resistant and susceptible chickpea cultivars. The expression of fungal pathogenesis related genes and their race specific response was determined throughout the course of chickpea-Foc interaction. Temporal expression and race specific response of plant defense related and fungal virulence genes were studied in the resistant and susceptible cultivars of chickpea inoculated with three races of Foc highlighting the host-pathogen interactions. Few genes, involved in chickpea defense against Fusarium wilt which were not reported previously were unveiled in this study.
The Effect of Compositional Variation on Physical Properties of Te9Se72Ge19-XSbx (X = 8, 9, 10, 11, 12) Glassy Material  [PDF]
Anant Vidya Nidhi, Vivek Modgil, V. S. Rangra
New Journal of Glass and Ceramics (NJGC) , 2013, DOI: 10.4236/njgc.2013.33015
Abstract:

The quaternary chalcogenide glass Te9Se72Ge19-xSbx (x = 8, 9, 10, 11, 12) has been prepared by the melt quench technique. The material fragility increases due to decrease in degree of cross linking in glass matrix as the Sb content increases. The heat of atomization decreases due to lower value of heat of atomization of antimony. The glass transition temperature is calculated by Tichy-Ticha and Lankhorst approaches. The glass seems to have high value of glass transition temperature as per theoretical calculations and is monotonically decreasing with increasing Sb content because increasing concentration of Sb reduces the cohesive energy and mean bond energy of the material.

Influence of Composite Non Magnetic Ions (Cd-Ti) Doping on Structural and Electrical Properties of Li-Mn Ferrite  [PDF]
Vidya J. Deshmukh, Pragati S. Jadhav, Ketaki K. Patankar, Sharad S. Suryawanshi, Vijaya R. Puri
New Journal of Glass and Ceramics (NJGC) , 2012, DOI: 10.4236/njgc.2012.24021
Abstract: The Li-Mn ferrites with composite divalent and tetravalent non-magnetic ions doping were prepared by ceramic method and studied for the first time to investigate their structural and electrical properties. It has been confirmed from the studies that these materials result in properties suitable for microwave applications. The structural properties have con- firmed the formation of cubic spinel ferrite and the substitutions of non magnetic ions have resulted in increase of unit cell dimensions and hence the grain size with increase in dopant content. An IR study asserts the same. Electrical Prop- erties show increase in dc resistivity and decrease in dielectric loss tangent with increase in dopant concentration.

A Comparative Analysis on Copy Move Forgery Detection in Spatial Domain Method Using Lexicographic and Non Lexicographic Techniques
Vidya S. Pujari Prof. Mandar Sohani
International Journal of Electronics Communication and Computer Engineering , 2012,
Abstract: A digitally altered image, often leaving no visual clues of having been tampered with, can be indistinguishable from an authentic image[1]. Authenticity of digital images plays important role in various fields like medical, legal, criminal, and journalism. Due to rapid advances and availabilities of powerful image processing software, digital images are easy to manipulate and modify for ordinary people. This makes it more and more difficult for a viewer to check the authenticity of a given digital image. In the fields such as forensics, medical imaging, e-commerce, and industrial photography, authenticity and integrity of digital images is essential. This motivates the need for detection tools that are transparent to tampering and can tell whether an image has been tampered just by inspecting the tampered image[3]. Copying parts of an image and pasting in the same image for covering unwanted information or creating a fake image by splicing two or more images are most used techniques in digital image manipulation. These are called copy-move and image-splicing techniques respectively. In this paper we focus on copy-cover image forgery using spatial domain method and do the comparative analysis for lexicographic and non lexicographic techniques.
Dental caries vaccine
Shivakumar K,Vidya S,Chandu G
Indian Journal of Dental Research , 2009,
Abstract: Dental caries is one of the most common diseases in humans. In modern times, it has reached epidemic proportions. Dental caries is an infectious microbiologic disease of the teeth that results in localized dissolution and destruction of the calcified tissue. Dental caries is a mulitifactorial disease, which is caused by host, agent, and environmental factors. The time factor is important for the development and progression of dental caries. A wide group of microorganisms are identified from carious lesions of which S. mutans , Lactobacillus acidophilus , and Actinomyces viscosus are the main pathogenic species involved in the initiation and development of dental caries. In India, surveys done on school children showed caries prevalence of approximately 58%. Surveys among the U.S. population showed an incidence of 45.3% in children and 93.8% in adults with either past or present coronal caries. Huge amounts of money and time are spent in treating dental caries. Hence, the prevention and control of dental caries is the main aim of public health, eventually the ultimate objective of public health is the elimination of the disease itself. Recently, dental caries vaccines have been developed for the prevention of dental caries. These dental caries vaccines are still in the early stages.

Radha S,Afroz T,Vidya Sagar JVS
Indian Journal of Orthopaedics , 2006,
Abstract: Background: Pigmented villonodular synovitis is a rare disorder affecting joints. Methods : We reviewed 19 cases of pigmented villonodular synovitis out of 481 arthroscopic synovial biopsies over a period of ten years. A common presenting symptom was locking. Both diffuse and localized forms were diagnosed. Duration of symptoms varied from 5 months to3 years. We report our experience of patients treated by arthroscopic excision for localized villonodular synovitis and arthroscopic synovectomy for diffuse villonodular synovitis followed by intraarticular Yttrium. Results : In diffuse villonodular synovitis arthroscopic total synovectomy was done a using special angular and straight motorized shaver through different portals to reach all corners of the joint. Localized variety was treated by excising the pedicle attached to the synovium. In our series none of the patients with localized villonodular synovitis showed recurrence till date. Three cases of diffuse variety presented with effusion and swelling three to six months after treatment and were managed by arthoscopic synovial shaving. Two cases who showed recurrence after one year were subjected to intraarticular 90Y isotope injection. Conclusion : Arthroscopic synovectomy helps in reducing morbidity. Radiation and intraarticular Injection of 90 Y are alternative modes of treatment.
