Influence of Organic Manures on Yield and Quality of Rice (Oryza sativa L.) and Blackgram (Vigna mungo L.) in Rice-Blackgram Cropping Sequence  [PDF]
S. P. Sangeetha, A. Balakrishnan, P. Devasenapathy
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.45141

Field experiments were conducted at Tamil Nadu Agricultural University, Coimbatore during rabi and summer seasons of 2007-2008 and 2008-2009 to study the influence of organic manures (enriched farmyard manure compost, vermicompost, farmyard manure + neem cake, enriched farmyard manure compost + vermicompost + farmyard manure, composted poultry manure and enriched poultry manure compost) and recommended NPK fertilizers on yield and quality of rice and blackgram in rice-blackgram cropping sequence. Based on field experiments, it was found that the application of enriched poultry manure compost on equal N basis (2.3 t·ha-1) recorded higher yield attributes and grain yield of rice (4675 kg·ha-1 in 2007 and 4953 kg·ha-1 in 2008), which was however comparable with composted poultry manure. The application of recommended NPK fertilizers recorded higher physical characteristics and cooking qualities of rice, which was comparable with enriched poultry manure compost. Higher sensory score was registered in enriched poultry manure compost as compared to recommended NPK through fertilizers. After harvesting of rice, the residual effect of enriched poultry manure compost and composted poultry manure applied to preceding rice crop improved yield attributes and yield of

Efficient Optimization Algorithm for Dwindling Payment and Power Management  [PDF]
P. Sangeetha, S. Suja
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.79186
Abstract: In this current era, rising demand ultimately leads to the scarcity of source in terms of power. To fulfill this inadequacy and because of the availability and easy conversion of electrical energy, hybrid energy system is the best choice for non renewable energy source replacement, which dominates the demand of reliable power. In this paper, we have proposed and analyzed the optimal capacity of the Photovoltaic and Wind as a hybrid system, standing as a foremost motivating force for the public improvement. To provide uninterrupted supply, storage device is used along with the integrated sources. The key pioneering part of this research paper is the performance of the projected system for cost optimization, which is realized by running the Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) algorithms. The result is the baseline system cost necessary to meet the load requirements. The above stated process is implemented using MATLAB. The motivation of choosing these algorithms is because of swift convergence in real time power management. Performance parameter Total Harmonic Distortion (THD) is also calculated for the proposed system.

Abstract: In the field of multimedia signal processing, image inpainting is the technique commonly exploited for automatic filling-in the missing or unclear regions of an image without affecting the image quality. The region filling of the missing information is a exceedingly significant area in image processing, with large number of applications including image coding and wireless image transmission (e.g., recovering lost blocks), special effects (e.g., removal of objects) and image restoration (e.g., scratch removal). Inpainting techniques are also exploited to restore or enhance historical images which might have lost information through damage or scratch.Eliminating image interference or unnecessary portions of an image is another area inpainting. Exemplar-based inpainting is a technique which works well in cases of normal textures, where the lost information can be refilled by appropriate patches from the other areas of the same image. In this paper, the exemplar-based imageinpainting technique is extended by incorporating texture primitives for effective region filling. The main objective is to construct an image that appears to be 'normal', means that the viewer should not be able to find that the image has been inpainted. The performance is evaluated in terms of Mean Squared Error (MSE) and Peak Signal-to-Noise Ratio (PSNR).
Improved Exemplar Based Texture Synthesis Method for Natural Scene Image Completion
K. Sangeetha,Dr. P. Sengottuvelan,E. Balamurugan
International Journal of Computer Science Issues , 2011,
Abstract: Image inpainting or image completion refers to the process of filling in the missing data of an image in a visually plausible way. Given a natural scene input image with selected target regions, both the geometrical property and texture information should be propagated from the known parts of image into the target regions. Exemplar-based model fills the target region using the source exemplars in the known parts of image. Many works on this subject have been proposed these recent years. In this paper, we present an inpainting method based on the improved exemplar-based texture synthesis technique which includes image gradient information during the inpainting process. A comparison with some existing methods on different natural images shows the strength of the proposed approach.

P. Dhasarathan, N. Reeshma Devi, P. Sangeetha, Suman Madhu G. Navaraj, A. J. A. Ranjitsingh, C. Padmalatha
Advances in Nanoparticles (ANP) , 2018, DOI: 10.4236/anp.2018.74007
Abstract: In the present study silver nanoparticles (AgNPs) were synthesized using leaves of bamboo plant, Bambus vulgaris and the size of the nanoparticles was confirmed using XRD, EDAX, SEM, TEM, PSA analysis. The antimicrobial activity of the synthesized NPs showed a good antibacterial activity against the waterborne isolates, E. coli, Staphyllococcus aureus, Vibrio cholera and Salmonella sp. Further the anti algal activity of the NPs was tested against the algae, Dictyosphaerium pulchellum, and Algoriphagus chordate. The SEM studies revealed that the AgNPs breaks the cell wall of algae and inhibits the growth. The safe dose of AgNPs can be used in aquaculture farms, household water tanks and other small water bodies to wipe out waterborne pathogens and algal bloom.

K.G. Kripa,R. Sangeetha,P. Madhavi,P. Deepthi
Pakistan Journal of Biological Sciences , 2011,
Abstract: This study was proposed based on the folklore claim and on the scarcity of scientific evidence from the literature for the medicinal uses of Breynia retusa. The aim of the present study was to analyse the phytochemical constituents of the leaves of B. retusa. The fractions obtained by successive fractionation using solvents of varying polarity were studied for the presence of primary and secondary metabolites and the total phenolic content of the different fractions were determined by HPLC. The results of the study support the traditional acclaim of the therapeutic uses of B. retusa. The potential of B. retusa to inhibit a-amylase, a prime enzyme involved in carbohydrate metabolism was analysed and it was observed that the ethyl acetate and methanolic extract of the leaves of B. retusa possessed in vitro amylase inhibitory activity.
Pre-donation deferral of blood donors in South Indian set-up: An analysis
Sundar P,Sangeetha S,Seema D,Marimuthu P
Asian Journal of Transfusion Science , 2010,
Abstract: Background: It is well known that quite a large number of apparently healthy donors are not able to donate blood successfully because of varied reasons. Aim: We want to analyze the rate and various reasons for deferrals. Materials and Methods: A retrospective analysis of records of the donors, for 3 years, from January 2005 to December 2007 was done, in order to find out the rate and causes of deferral in four categories of age groups, both in male and female, in our Transfusion Medicine Centre, Bangalore, India. Result: There were 16,706 donors, of which 976 donors were deferred (5.84%) for various reasons. Of the 16,706 donors registered for donation, females constituted only 11.27%. And deferral rate was about five times more for female (19.85%) compared to male (4.06%). The three most common reasons for deferral in female were low hemoglobin levels, low body weight, and hypotension. The deferral rate was higher in the age group of 18-25 years and most common cause was low hemoglobin level. In male, the three most common reasons for deferral were hypertension, under weight, and low hemoglobin levels. The deferral rate varied from 4 to 15% as reported in the literature. The most common cause of deferral in our study and in several studies available in the literature is the same.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0012221
Abstract: Cord blood (CB) is a promising source for hematopoietic stem cell transplantations. The limitation of cell dose associated with this source has prompted the ex vivo expansion of hematopoietic stem and progenitor cells (HSPCs). However, the expansion procedure is known to exhaust the stem cell pool causing cellular defects that promote apoptosis and disrupt homing to the bone marrow. The role of apoptotic machinery in the regulation of stem cell compartment has been speculated in mouse hematopoietic and embryonic systems. We have consistently observed an increase in apoptosis in the cord blood derived CD34+ cells cultured with cytokines compared to their freshly isolated counterpart. The present study was undertaken to assess whether pharmacological inhibition of apoptosis could improve the outcome of expansion.
