Timeserving Routing Protocol Implementation to accomplish best throughput and fairness
Narasimha Rao V L Potta,B. Sarath Kumar
International Journal of Computer & Electronics Research , 2012,
Abstract: The latest technology for next generation Wireless networking is Wireless Mesh Networks (WMNs), with low cost and easy deploying. The WMNs are desirable for communication paradigm. The WMNs are more advantageous over other wireless networks. The existing routing protocols which transmits the traffic through pre-determined path which don’t provide security. This paper proposes a routing protocol called simplistic constructive routing protocol (SPRP) which supports multiple flows in wireless mesh networks. There are four major components in the SPRP which provides fairness and high throughput: 1) To minimize the multiple data transmissions Constructive forwarding path selection to provide multiple paths while minimizing duplicate transmissions, 2) Constructive rate control to determine an appropriate transfer rate according to the current network conditions. 3) Inter node loss recovery to efficiently find and resend lost packets, and 4) clock-based forwarding to let only the priority node to forward the traffic. Our result shows that SPRP significantly performs existing routing and a pivotal time serving routing protocol.

Mahendra, K,Narasimha Rao, C.V,Murthy, Y.L.N,Bala Murali Krishna, K
International Journal of Chemical Sciences and Research , 2011,
Abstract: In Indian agriculture, tobacco has a prominent place. Tobacco could be developed as an important food crop in combination with its traditional use for smoking and chewing. Use of tobacco for either smoking or chewing purpose is viewed seriously due to alleged health factors. The chemistry of tobacco is unique with the presence of a wide spectrum of chemical compounds of which nicotine, solanesol, malic and citric acid were identified as potential chemicals which could be recovered and converted to value-added products. This situation necessitated to examine the green tobacco crop as a source for recovery of phytochemicals alone. With the objective of maximizing bio-mass production for optimum recovery of proteins, nicotine, solanesol and organic acids from green tobacco, a field experiment was conducted by manipulating agronomic practices. Flue-cured tobacco variety was planted to have a high density population. Green leaf was harvested in six pauses for processing. An integrated approach was developed for extraction of above phytochemicals from green leaf and recovery potential was estimated. The green lamina was macerated and filtered through a cheese cloth, the green liquid was heat coagulated at 80°C to precipitate the crude protein along with chloroplast protein. Remaining after protein separation, brown liquid containing nicotine, was passed through a strongly cationic-exchange resin. The wet green mass left over after filtration is subjected to hexane extraction for the recovery of solanesol. Processing of chloroplast fraction for recovery of solanesol will be standardized. The column effluent after nicotine recovery is treated with lime to precipitate organic acids. Results indicated that tobacco cultivation for phytochemicals is a prospective proposition. The need to evolve proper marketing systems for the phytochemicals or their value-added products is also discussed

Velluru Sridevi, M. V. V Chandana Lakshmi, A. V. N Swamy, M Narasimha Rao
Advances in Bioscience and Biotechnology (ABB) , 2011, DOI: 10.4236/abb.2011.24028
Abstract: Removal efficiency of phenol from aqueous solutions was determined using Pseudomonas putida (NCIM 2102). Experiments were made as a function of pH (4 - 9), temperature (28 - 36oC), and agitation speed (100 - 200 rpm). Optimization of these three process parameters for phenol degradation was studied. Statistically designed experiments using response surface methodology was used to get more information about the significant effects and the interactions between these three parameters. A 23 full-factorial central composite design was employed for experimental design and for analysis of the results. A second order polynomial regression model, has been developed using the experimental data. It was found that the degrading potential of P.putida (NCIM 2102) was strongly affected by the variations in pH, temperature and agitation speed. The experimental values were in good agreement with the predicted values and the correlation coefficient was found to be 0.9871. The optimum process conditions for maximizing phenol degradation were recognized as follows: pH (7.49), temperature (29.99oC), and agitation speed (138.89) rpm.
INFLUENCE OF SOIL-INDUSTRIAL EFFLUENTS INTERACTION ON SUBGRADE STRENGTH OF AN EXPANSIVE SOIL-A COMPARATIVE STUDY
A. V. Narasimha Rao,M. Chittaranjan
International Journal of Advances in Engineering and Technology , 2012,
Abstract: The rapid growth in population and industrialization cause generation of large quantities of effluents. The bulk effluents generated from industrial activities are discharged either treated or untreated over the soil leading to changes in soil properties causing improvement or degradation of engineering behaviour of soil. If there is an improvement in engineering behaviour of soil, there is a value addition to the industrial wastes serving the three benefits of safe disposal of effluent, using as a stabilizer and return of income on it. If there is degradation of engineering behaviour of soil then solution for decontamination is to be obtained. Hence an attempt is made in this investigation to study the effect of certain Industrial effluents such as Textile effluent, Tannery effluent and Battery effluent on the California Bearing Ratio Value of an expansive soil.

Abstract:
Background and Aim: Newer generation coronary stent systems with low profile metallic frame, biodegradable polymer coating and potent but safe anti-restenosis drug from “limus family” are emerging as safe and effective stents. To evaluate the safety and performance of Metafor SES (Meril life Sciences Pvt. Ltd., Vapi, India) in consecutive patients in a real-world population. Methods: The study was a retrospective, non-randomized, single-center study which evaluated the data of 127 patients who underwent percutaneous coronary intervention (PCI) treated with Metafor SES from February 2012 to February 2015 and mean follow-up period of those patients was 3.6 ± 0.6 years. The primary endpoint was a major adverse cardiac event (MACE) including cardiac death, myocardial infarction (MI), and target lesion revascularization (TLR). In addition, Stent thrombosis (ST) was analyzed at respective follow-up period. Results: A total of 127 patients (mean age: 53.70 ± 8.41 years and 99 males) were included. Among those 80 (63%) patients had hypertension and 58 (45.7%) patients with diabetes mellitus.At follow-up, MACE in form of TLR was observed in 2 (1.6%) patients only. No cardiac death or stent thrombosis was reported in any patient. A total of 169 lesions were treated with the Metafor SES (1.3 stents per lesion). The 38.4% of patients treated with the Metafor SES with lesion length ≥24 mm, and the procedural success was 100%. Conclusions: The lower incidence of MACE in uncontrolled and real world population at long term follow-up clearly depicts the prolonged safety and performance of the Metafor SES.

International Journal of Engineering Science and Technology , 2010,
Abstract: Due to rapid industrialization throughout the world, the production of huge quantity of produced waste materials creates not only the environmental problem but also the depositional hazards. Many procedures have been developed to improve the mechanical properties of soil by incorporating a wide range of stabilizing agents, additives and conditioners. In this paper, an attempt has been made to utilize industrial wastes like Rice Husk Ash (RHA), Fly Ash (FA) and Ground Granulated Blast furnace Slag (GGBS) as stabilizing agents. In addition to these, Lime was also added as stabilizing agent. The effect of Lime, RHA, FA and GGBS on certain properties of soil such as Optimum moisture content (OMC), Maximum Dry Density(MDD), Unconfined Compressive Strength (UCS) and California Bearing Ratio (CBR) has been studied. It has been established by experiments conducted on the samples that there is a maximum change in the properties with addition of lime up to 5%, RHA and GGBS up to 15% per cent and FA up to 20%. Of all the admixtures, Lime shows considerable increase in strength characteristics at an optimum lime content of 5% which gave maximum.

Abstract: Mining the sand, from riverbed is hazardous to environment. The deep pits dig in the riverbed for sand mining effects on ground water level and erode the nearby land. Most of the provincial Governments in India have imposed ban on mining sand from riverbeds. In such a situation the quarry waste can be an alternative to river sand .The present paper deals with the experimental investigation on the performance of quarry waste in fly ash gypsum slurry. The flow ranges selected for the study are 500± 25mm, 425± 25mm, 375±25mm, 300±50mm, & 150±50mm. The content of the quarry waste in the mix was increased from 0% to 50% for each of the above flows. Twenty mixes were proportioned and used in the study. These mixes were evaluated for flowability and compressive strength. Results indicate that quarry waste in fly ash gypsum slurry showed satisfying performance and suitable for a wide range of applications.
