A STUDY ON THE INFLUENCE OF LIME ON FLYASH TREATED MARINE CLAY
D. Koteswara Rao,M. Sruthi,R. Suryaditya
International Journal of Engineering Science and Technology , 2011,
Abstract: Different types of soils are available in our country, but some of them are not suitable for pavement design. Since India is a peninsular country, a vast area coming under coastal region. The soil which exists in these coastal regions is marine clay and is generally weak and highly compressible in nature. Since there is a great need for improving the transportation facilities in coastal regions, it is essential to improve the marine clay for the construction of pavements, because the successful performance of the pavement depends on the nature of subgrade soil. In the present study the geotechnical properties of marine clay i.e. OMC & MDD, CBR, Atterberg limits , DFS and strength characteristics were determined before and after treatment by using flyash and lime.

STABILIZATION OF EXPANSIVE SOIL WITH RICE HUSK ASH, LIME AND GYPSUM – AN EXPERIMENTAL STUDY
Koteswara Rao. D,Pranav. P.R.T,Anusha. M
International Journal of Engineering Science and Technology , 2011,
Abstract: The problem with expansive soils has been recorded all over the world. In monsoon they imbibe water and swell and in summer they shrink on evaporation of water there from. Because of this alternativeswelling and shrinkage, lightly loaded civil engineering structures like residential buildings, pavements and canal linings are severely damaged. It is, therefore, necessary to mitigate the problems posed byexpansive soils and prevent cracking of structures. Many innovative foundation techniques have been devised as a solution to the problem of expansive soils. The chief among them are sand cushion technique,cohesive non-swelling (CNS) layer technique and under reamed piles. Stabilization of expansive clays with various additives has also attained lot of success. In this study, rice husk ash, lime and gypsum are added to the expansive soil which resulted in considerable improvement in the strength characteristics of the expansive soil.
THE EFFICACY OF REINFORCEMENT TECHNIQUE ON THE FLY ASH STABILIZED EXPANSIVE SOIL AS A SUBGRADE EMBANKMENT FOR HIGHWAYS
KOTESWARA RAO.D
International Journal of Engineering Science and Technology , 2011,
Abstract: The most significant factor that influencing the design thickness of a flexible pavement overlay is rebound deformation from repeated load application and subgrade support values . It is essential to stabilize and reinforce the poor soils to bear the traffic intensity or truck loading. Different types of materials are provided with stabilization techniques to achieve suitable performance and to reduce maintenance costs and also to provide required service life for the subgrade embankments. In the present study, the effect of geo-textile as a reinforcement in the sub grade embankment is verified by conducting cyclic plate load tests. Locally available soil is mixed with optimum of fly ash and then this mixer is stabilized with optimum of CaCl2 for the construction of sub grade embankment with and with out reinforcement. Compaction properties and C.B.R values are determined for the locally available soil and categorized as CH soil as per IS classification, fly ash, fly ash - CaCl2 mix with the CH soil. The introduction of geo-textile has been reduced the deformation and increased the load carrying capacity as was revealed by cyclic plate load tests.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0076189
Abstract: Background Multi drug resistant and rifampicin resistant TB patients in India are treated with the World Health Organization (WHO) recommended standardized treatment regimens but no guidelines are available for the management of isoniazid (INH) resistant TB patients. There have been concerns that the standard eight-month retreatment regimen being used in India (2H3R3Z3E3S3/1H3R3Z3E3/5H3R3E3; H-Isoniazid; R-Rifampicin; Z-Pyrazinamide; E-Ethambutol; S-Streptomycin) may be inadequate to treat INH resistant TB cases and leads to poor treatment outcomes. We aimed to assess if INH resistance is associated with unfavorable treatment outcomes (death, default, failure and transferred out) among a cohort of smear positive retreatment TB patients registered in three districts of Andhra Pradesh, India. Methods We conducted a retrospective record review of all smear positive retreatment TB patients without rifampicin resistance registered during April–December 2011. Results Of 1,947 TB patients, 1,127 (58%) were tested with LPA—50 (4%) were rifampicin resistant, 933 (84%) were sensitive to INH and rifampicin and 144 (12%) were INH resistant. Of 144 INH resistant cases, 64 (44%) had poor treatment outcomes (25 (17%) default, 22 (15%) death, 12 (8%) failure and 5 (3%) transfer out) as compared to 287 (31%) among INH sensitive cases [aRR 1.46; 95%CI (1.19–1.78)]. Conclusion Our study confirms that INH resistance is independently associated with unfavorable treatment outcomes among smear positive retreatment TB patients, indicating that the current treatment regimen may be inadequate. These findings call for an urgent need for randomized controlled trials to discover the most effective treatment regimen for managing INH resistant TB.
Decision Support for E-Governance: A Text Mining Approach
G. Koteswara Rao,Shubhamoy Dey
International Journal of Managing Information Technology (IJMIT) , 2011,
Abstract: Information and communication technology has the capability to improve the process by whichgovernments involve citizens in formulating public policy and public projects. Even though much ofgovernment regulations may now be in digital form (and often available online), due to their complexityand diversity, identifying the ones relevant to a particular context is a non-trivial task. Similarly, with theadvent of a number of electronic online forums, social networking sites and blogs, the opportunity ofgathering citizens’ petitions and stakeholders’ views on government policy and proposals has increasedgreatly, but the volume and the complexity of analyzing unstructured data makes this difficult. On the otherhand, text mining has come a long way from simple keyword search, and matured into a discipline capableof dealing with much more complex tasks. In this paper we discuss how text-mining techniques can help inretrieval of information and relationships from textual data sources, thereby assisting policy makers indiscovering associations between policies and citizens’ opinions expressed in electronic public forums andblogs etc. We also present here, an integrated text mining based architecture for e-governance decisionsupport along with a discussion on the Indian scenario.
Framework to Integrate Business Intelligence and Knowledge Management in Banking Industry
G. Koteswara Rao,Roshan Kumar
Computer Science , 2011,
Abstract: In this digital age organizations depend upon the technologies to provide customer-centric solutions by understanding well about their customers' behaviour and continuously improving business process of the organization. Business intelligence (BI) applications will play a vital role at this stage by discovering the knowledge hidden in internal as well as external sources. On the other hand, Knowledge Management (KM) will enhance the organisations performance by providing collaborative tools to learn, create and share the knowledge among the employees. The main intention of the BI is to enhance the employees' knowledge with information that allows them to make decisions to achieve its organisational strategies. However only twenty percent of data exist in structured form, majority of banks knowledge is in unstructured or minds of its employees. Organizations are needed to integrate KM with Knowledge which is discovered from data and information. The purpose of this paper is to discuss the need of business insiders in the process of knowledge discovery and distribution, to make BI more relevant to business of the bank. We have also discussed about the BI/KM applications in banking industry and provided a framework to integrate BI and KM in banking industry.

THE INFLUENCE OF POTASSIUM CHLORIDE ON THE REINFORCED MARINE CLAY FOR FOUNDATION SOIL BEDS
Koteswara Rao,,D J. Purna Chandra Rao
International Journal of Engineering Science and Technology , 2011,
Abstract: Weak marine soil deposits have been found both on the coast and in several offshore areas spread over many parts of the world. When clay particles precipitate in salt water, there is a tendency for the clayparticles to flocculate and stick together giving rise to some sort of edge-to-face arrangement. As a result, clay, silt, and fine sand particles settle almost at the same rate and the final sediment formed consists of particles with a very loose card house-like structure. Hence the marine sediments can be considered loose sediments, usually formed with high void ratios. Problems are associated with these fine-grained soils deposited at a soft consistency. Fine-grained soils are very sensitive to changes in the stress system, moisture content and system chemistry of the pore fluid. In addition to these, the problems arising out ofhigh compressibility and low shear strength of these weak marine deposits expose geotechnical engineers to considerable changes in the construction of various coastal and offshore structures. In this present investigation, the performance of the potassium chloride on the strength characteristics of the marine clay has been studied and also the reinforcement effect on the improvement of load bearing capacity of the KCl treated marine clay has been studied.
