GANDHIJI’S VISION EXHIBITED IN THE NOVELS OF R.K. NARAYAN
M. Sudha
The Dawn Journal , 2013,
Abstract: Gandhiji, a socio-political figure, struggled for the sake of India’s development and independence. He is an immense source of writing and has influenced different disciplines and many writers from different fields like history, politics, philosophy, literature, sociology, and so on. He served as a central figure for their writings. Gandhiji not only struggled for India’s independence but also taught the people of India to love one another and advised them to show bitterness towards non-violence. In this principle of non-violence Gandhiji introduces technique of resistance to evil and untruth. His Satyagraha is inspired by boundless love and compassion. It is opposed to sin and evil. Gandhiji was the speaker of truth and he does not like falsehood. These principles of Gandhiji were very well exhibited in the novels of R.K. Narayan. One or in another way the characters of the novels explore Gandhiji himself or his views. For example, in a novel called Waiting for Mahatma Gandhiji, himself has participated as a character. Bharati an important personality in the novel serves as a disciple of Gandhiji. The famous novels of R.K. Narayan were Swami and Friends (1935), The Bachelor of Arts (1937), The English Teacher (1945), Waiting for Mahatma (1955), The Vendor of Sweets (1967) were all set in Narayan’s imaginary town, Malgudi. It is not a place but an experience of soil and soul of India. The paper aims at analysing the novels of R.K. Narayan on this backdrop and it concludes that his novels serve as a panorama for the future generation, to know Gandhi as a whole.
Probiotics as complementary therapy for hypercholesterolemia
M Ratna Sudha
Biology and Medicine , 2009,
Abstract: The role of probiotic organisms as alternative or complementary therapy in combating large number of gastrointestinal disorders and their ability to enhance immune response attracts global attention. In addition, theirtherapeutic use towards cholesterol-lowering activities has further increased their applications as effective probioticsfor humans as supplements in milk and yoghurt, since there are no other supplements for hypercholesterolemia,which is the crucial risk factor for cardiovascular diseases. Changes in dietary habits, stressful life and lack ofphysical activities are the precursors for increasing incidences of hypercholesterolemia and subsequentlycardiovascular diseases. The present review focuses on some of the animal studies and clinical trials conducted withprobiotic lactobacilli and bifidobacteria. This review may throw some light to prove the ability of these probiotics as anovel alternative or adjuvants to chemical drugs to help fight hypercholesterolemia.
MINIMUM RULE BASED PID SLIDING MODE FUZZY CONTROL TECHNIQUES FOR BRUSHLESS DC MOTOR DRIVES
C. Navaneethakkannan,M. Sudha
International Journal of Advances in Engineering and Technology , 2012,
Abstract: In this paper, a mathematical tunable gain model free PID - like sliding mode fuzzy controller (PIDSMFC) is designed to rich the best performance. Sliding mode fuzzy controller is studied because of its model free,stable and high performance. Today, most of systems are used in unknown and unstructured environment and caused to provide sophisticated systems, therefore strong mathematical tools (e.g., nonlinear sliding mode controller) are used in artificial intelligent control methodologies to design model free nonlinear robust controller with high performance (e.g., minimum error, good trajectory, disturbance rejection). Non linear classical theories have been applied successfully in many applications, but they also have some limitation. One of the most important challenging in pure sliding mode controller and sliding mode fuzzy controller is sliding surface slope. Thispaper focuses on adjusting the gain updating factor and sliding surface slope in PID-like sliding modefuzzy controller to have the best performance and reduce the limitation.
A Protection Scheme for Three-Phase Induction Motor from Incipient Faults Using Embedded Controller
M. Sudha,P. Anbalagan
Asian Journal of Scientific Research , 2009,
Abstract: This study presents a protection scheme for three-phase induction motor from incipient faults using embedded microcontroller. The induction motor experiences several types of electrical faults like over/under voltage, over load, phase reversing, unbalanced voltage, single phasing and earth fault. Due to these electrical faults, the windings of the motor get over heated which lead to insulation failure and thus reduce the life time of the motor. To analyze the behavior of induction motor during electrical faults, the induction motor is modeled using arbitrary reference frame theory in MATLAB/Simulink environment; the faults are created and the variation of the induction motor parameters under faulty conditions are observed. Based on the analysis, embedded controller is developed to protect the motor from incipient faults.
Optimization of Ceric Ammonium Nitrate Initiated Graft Copolymerization of Acrylonitrile onto Chitosan  [PDF]

Journal of Water Resource and Protection (JWARP) , 2011, DOI: 10.4236/jwarp.2011.36048
Abstract: In the present work, graft copolymerization of polyacrylonitrile onto chitosan has been carried out in the presence of ceric ammonium nitrate redox initiator. Optimization of grafting of polyacrylonitrile onto chito-san was performed by varying the process parameters such as ceric ammonium nitrate (CAN) concentration, polyacrylonitrile concentration and reaction time to study their influence on percent grafting and grafting ef-ficiency. The optimum reaction conditions obtained for grafting of acrylonitrile onto chitosan were reaction time 55 mins, CAN concentration 1% in Con. HNO3, and polyacrylonitrile concentration 0.75 mol/L. The characterization of the grafted products by means of FTIR, thermal analysis, X-ray diffraction and scanning electron microscopy furnished the evidence of grafting of polyacrylonitrile onto chitosan.
Effect of different concentrations of metal ions on alpha amylase production by Bacillus amyloliquefaciens
Sudha
Research in Biotechnology , 2012,
Abstract: Bacillus amyloliquefaciens is obtained from soil which produces extracellular alphaamylase enzyme. The present study is concerned with effect of metal ions on alpha amylaseproduction. Metal ions are Ca2+, Cu2+, Mg2+, Fe2+ and Mn2+ at different concentrations 2g/l,5g/l and 7g/l. Supplementations of salts of certain ions provide good growth ofmicroorganism and production of alpha amylase. Ca2+and Mg2+exhibit positive influence onalpha-amylase production. Our results show that the amylase production is higher in thepresence of Ca2+ (0.439) IU/ml/min at 7g/l concentration in comparison of other metal ions.The enzyme activity of Mg2+(0.321) IU/ml/min at 2g/l concentration. The study focuses onsupplementation of metal ions increase the production of amylase.
Human RECQ1 Is a DNA Damage Responsive Protein Required for Genotoxic Stress Resistance and Suppression of Sister Chromatid Exchanges
Sudha Sharma, Robert M. Brosh
PLOS ONE , 2007, DOI: 10.1371/journal.pone.0001297
Abstract: Background DNA helicases are ubiquitous enzymes that unwind DNA in an ATP-dependent and directionally specific manner. Unwinding of double-stranded DNA is essential for the processes of DNA repair, recombination, transcription, and DNA replication. Five human DNA helicases sharing sequence similarity with the E. coli RecQ helicase have been identified. Three of the human RecQ helicases are implicated in hereditary diseases (Bloom syndrome, Werner syndrome, and Rothmund-Thomson syndrome) which display clinical symptoms of premature aging and cancer. RECQ1 helicase is the most highly expressed of the human RecQ helicases; however, a genetic disease has yet not been linked to mutations in the RECQ1 gene, and the biological functions of human RECQ1 in cellular DNA metabolism are not known. Methodology/Principal Findings In this study, we report that RECQ1 becomes phosphorylated upon DNA damage and forms irradiation-induced nuclear foci that associate with chromatin in human cells. Depletion of RECQ1 renders human cells sensitive to DNA damage induced by ionizing radiation or the topoisomerase inhibitor camptothecin, and results in spontaneous γ-H2AX foci and elevated sister chromatid exchanges, indicating aberrant repair of DNA breaks. Consistent with a role in homologous recombinational repair, endogenous RECQ1 is associated with the strand exchange protein Rad51 and the two proteins directly interact with high affinity. Conclusion/Significance Collectively, these results provide the first evidence for a role of human RECQ1 in the response to DNA damage and chromosomal stability maintenance and point to the vital importance of RECQ1 in genome homeostasis.
