An analysis of docking study on tuberculosis inhibitors
Anuja Rangi,Saroj Rani,Savita Kumari,Sudhir Kumar
International Journal of Bioinformatics Research , 2010,
Abstract: In the present paper nine molecules has been docked in the Acyl-CoA carboxylasecarboxyltransferase domain 5 (AccD5) at GLY-193, GLY-194, GLY-434, ALA-435 pocket with very lowenergies. Six binding site on the crystallographic structure of AccD5 are examined with the structure-baseddesign program DOCK. The active compounds found are polycyclic (aromatic as well as aliphatic) andnitrogen heterocyclic. Each molecule gave a good number of conformations showing the flexible behavior ofthe ligand. The total energy of receptor-ligand complexes has also been calculated.
Antioxidant Potential Some Medicinal Plants of Central India  [PDF]
Savita Dixit, Huma Ali
Journal of Cancer Therapy (JCT) , 2010, DOI: 10.4236/jct.2010.12014
Abstract: Cellular damage or oxidative injury arising from free radicals or reactive oxygen species (ROS) now appears the fun-damental mechanism underlying a number of human neurodegenerative disorder, diabetes, inflammation, viral infec-tions, autoimmune pathologies and digestive system disorders. Free radicals are generated through normal metabolism of drugs, environmental chemicals and other xenobiotics as well as endogenous chemicals, especially stress hormones (adrenalin and noradrenalin). Accumulated evidence suggests that ROS can be scavenged through chemoprevention utilizing natural antioxidant compounds present in foods and medicinal plants. In this review, research on the antioxi-dant potential of some medicinal plants of origin of Central India is considered.4CdBw3
Relative Equilibria of a Satellite Moving in an Elliptic Orbit Subjected to Gravitational and Aerodynamic Torques  [PDF]
Kumari Ranjana
International Journal of Astronomy and Astrophysics (IJAA) , 2014, DOI: 10.4236/ijaa.2014.41019
Abstract: Here we consider the attitude motion of a satellite, subjected to gravitational and aerodynamic torques in an elliptic orbit. The determination of orientation of equilibrium points has been discussed. It is found that they coincide with those for the circular case as studied by Sarychev and others in the works [1]-[3] and besides we have aimed at the sufficient condition for stability in the sense of Lyapunov.
Studies on the Biology and Predatory Potential of Harmonia dimidiata, a Major Predator of Aphis pomi De Geer on Apple Host in India  [PDF]
Meena Kumari
Advances in Entomology (AE) , 2018, DOI: 10.4236/ae.2018.62013
Abstract: Observations were made on young nursery plants and apple orchards to record the coccinellid predators of Aphis pomi De Geer on apple plants in Himachal Pradesh which is main apple growing state of India. Nine species of lady bird beetles were observed feeding on green apple aphid, Aphis pomi De Geer on the apple nursery plants of Mashobra locality of Shimla district and Ner Chowk locality of Mandi district of Himachal Pradesh, India. On the basis of general observations, it was found that the larvae of beetle Harmonia dimidiata (F.), are very active to feed on the nymphs of green apple aphid. Therefore, it was considered worthwhile to investigate the biology and feeding potential of this beetle on green apple aphid from biological control point of view.
Vaccines against human papilloma virus and cervical cancer: An overview
Sharma Savita
Indian Journal of Community Medicine , 2008,
Abstract: The paradigm of preventing human papilloma virus (HPV) infection through currently approved vaccines, namely, Gardasil, manufactured by Merck and Co., Inc. (Whitehouse Station, NJ) and Cervarix, manufactured by GlaxoSmithKline (GSK, Philadelphia) holds tremendous promise for the developing countries in decreasing the burden of HPV infection and its sequelae, such as cervical cancer, genital warts and anogenital cancers. Effective screening programs that have reduced the burden of this killer disease in the developed countries are still lacking in India, despite the high incidence of cervical cancer and the implementation of the National Cancer Control Programme since 1975. The recent breakthrough in the global war against cervical cancer will provide new insight for meeting the future challenge of the prevention of cervical cancer in India.
A Novel Technique to Image Annotation using Neural Network
Pankaj Savita
International Journal of Computer Applications and Information Technology , 2013,
Abstract: Automatic annotation of digital pictures is a key technology for managing and retrieving images from large image collection. Traditional image semantics extraction and representation schemes were commonly divided into two categories, namely visual features and text annotations. However, visual feature scheme are difficult to extract and are often semantically inconsistent. On the other hand, the image semantics can be well represented by text annotations. It is also easier to retrieve images according to their annotations. Traditional image annotation techniques are time-consuming and requiring lots of human effort. In this paper we propose Neural Network based a novel approach to the problem of image annotation. These approaches are applied to the Image data set. Our main work is focused on the image annotation by using multilayer perceptron, which exhibits a clear-cut idea on application of multilayer perceptron with special features. MLP Algorithm helps us to discover the concealed relations between image data and annotation data, and annotate image according to such relations. By using this algorithm we can save more memory space, and in case of web applications, transferring of images and download should be fast. This paper reviews 50 image annotation systems using supervised machine learning Techniques to annotate images for image retrieval. Results obtained show that the multi layer perceptron Neural Network classifier outperforms conventional DST Technique.
Towards age/rotation/magnetic activity relation with seismology
Savita Mathur
Physics , 2015, DOI: 10.1051/epjconf/201510105005
Abstract: The knowledge of stellar ages directly impacts the characterization of a planetary system as it puts strong constraints on the moment when the system was born. Unfortunately, the determination of precise stellar ages is a very difficult task. Different methods can be used to do so (based on isochrones or chemical element abundances) but they usually provide large uncertainties. During its evolution a star goes through processes leading to loss of angular momentum but also changes in its magnetic activity. Building rotation, magnetic, age relations would be an asset to infer stellar ages model independently. Several attempts to build empirical relations between rotation and age (namely gyrochronology) were made with a focus on cluster stars where the age determination is easier and for young stars on the main sequence. For field stars, we can now take advantage of high-precision photometric observations where we can perform asteroseismic analyses to improve the accuracy of stellar ages. Furthermore, the variability in the light curves allow us to put strong constraints on the stellar rotation and magnetic activity. By combining these precise measurements, we are on the way of understanding and improving relations between magnetic activity, rotation, and age, in particular at different stages of stellar evolution. I will review the status on gyrochronology relationships based on observations of young cluster stars. Then I will focus on solar-like stars and describe the inferences on stellar ages, rotation, and magnetism that can be provided by high-quality photometric observations such as the ones of the Kepler mission, in particular through asteroseismic analyses.

Anuradha Kumari, Supriya Kumari, Dipo Mahto
Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.68144
Abstract: The present paper discusses the change in entropy of spinning black holes due to change in mass for AGN black holes on the basis of the model as proposed in the case of XRBs under condition that the black holes spin with unit spinning parameter and angular momentum and this model gives slightly some different nature of the super-massive spinning black holes in AGN as specified for XRBs.
