Similar erythrocyte sedimentation rate and C-reactive protein sensitivities at the onset of septic arthritis, osteomyelitis, acute rheumatic fever
Jonathan E. Reitzenstein,Loren G. Yamamoto,Hareesh Mavoori
Pediatric Reports , 2010, DOI: 10.4081/pr.2010.e10
Abstract: The erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are employed in the evaluation of patients with suspected septic arthritis, osteomyelitis, and acute rheumatic fever. The purpose of this study is to determine if one test has greater sensitivity (rises earlier) than the other. Laboratory data were retrieved for pediatric patients hospitalized with one of the above three conditions, who had both ESR and CRP tests done on or shortly prior to admission. Sensitivity calculations were performed for mild, moderate, and severe degrees of ESR and CRP elevation. Microcytic erythrocytes, as defined by mean corpuscular volume (MCV) less than 80 μL, were identified to see if this affects the ESR. ESR or CRP sensitivities depend on the cutoff value (threshold) chosen as a positive test. The sensitivities were similar for similar degrees of elevation. ESR and CRP discordance was not significantly related to MCV. We concluded that the CRP does not rise earlier than the ESR (their sensitivities are similar). Previously published conclusions are dependent on arbitrary thresholds. We could not find any evidence that MCV affects the ESR.

K. Hareesh, Ganesh Sanjeev
Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.211224
Abstract: Lexan polycarbonate films were irradiated by 8MeV electron beam at different fluences and characterized using X-ray Diffractogram (XRD), UV-Visible spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy, Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA). The structural parameters such as degree of crystallinity and crystallite size were found to decrease after irradiation due to chain-scission. he UV-Visible spectroscopic study show the formation of chromophore groups upon irradiation and was reduced at larger wavelength. FTIR Study shows the carbonate linkage was found to be the radiation-sensitive linkage and benzene ring does not undergo any changes after irradiation. The DSC studies showed a decrease in glass transition temperature and heat of fusion after irradiation due to chain-scission which indicates polymer was moving towards more disordered state. Thermal decomposition temperature of Lexan polycarbonate increases upon irradiation.

Peer to Peer Video on Demand Architecture using V-Chaining
Hareesh K,Manjaiah D. H
International Journal of Computers & Technology , 2012,
Abstract: In the Internet, video streaming requires greater amount of network bandwidth and other resources as the number of user requests increases. In case of traditional centralized directory server approach all the users requests are directly handled by the centralized server and each user request will send dedicated stream by the server, which requires higher end server, server cost will become more and greater amount of network bandwidth utilized by this server. To solve these problems peer to peer technology as emerged for the distribution of video streams to the larger requests over the network. In P2P VoD architecture adopted both the peer to peer and proxy based architectural design of a VOD system for larger community of users over the network. Hence our proposed Peer to Peer Video on Demand Architecture using V-Chaining improves the overall performance of the system by efficient utilization of uplink bandwidth and smaller amount of buffer space among the peers. In this paper we have introduce architecture for handle the large number of user requests over the communication network and ease of implementation.
Electron mobility in few-layer MoxW1-xS2

Physics , 2015,
Abstract: In this letter, we theoretically study the electron mobility in few-layer MoxW1-xS2 as limited by various scattering mechanisms. The room temperature energy-dependent scattering times corresponding to polar longitudinal optical (LO) phonon, alloy and background impurity scattering mechanisms are estimated based on the Born approximation to Fermi's Golden rule. The contribution of individual scattering rates is analyzed as a function of 2D electron density as well as of alloy composition in MoxW1-xS2. While impurity scattering limits the mobility for low carrier density (<2x1012 cm-2), LO polar phonon scattering is the dominant mechanism for high electron densities. Alloy scattering is found to play a non-negligible role for 0.5 < x < 0.7 in MoxW1-xS2. The LO phonon limited and impurity limited mobilities show opposing trends with respect to alloy mole fraction. The understanding of electron mobility in MoxW1-xS2 presented here is expected to aid the design and realization of hetero-structures and devices based on alloys of MoS2 and WS2.

Hareesh. K,Manjaiah D. H
Computer Science , 2011, DOI: 10.5121/ijp2p.2011.2401
Abstract: Peer-to-Peer Live streaming and Video on Demand is the most popular media applications over the Internet in recent years. These systems reduce the load on the server and provide a scalable content distribution. A new paradigm of P2P network collaborates to build large distributed video applications on existing networks .But, the problem of designing the system are at par with the P2P media streaming, live and Video on demand systems. Hence a comprehensive design comparison is needed to build such kind of system architecture. Therefore, in this paper we elaborately studied the traditional approaches for P2P streaming architectures, and its critical design issues, as well as practicable challenges. Thus, our studies in this paper clearly point the tangible design issues and its challenges, and other intangible issues for providing P2P VoD services.
High transport critical currents in dense, metal-clad superconductor wires of MgB2

Physics , 2001,
Abstract: In this letter, we report the first successful fabrication of dense, metal-clad MgB2 superconductor wires as well as the first demonstration of high transport Jc of greater than 36,000 A/cm2 in MgB2. The fabrication technique that we devised uses only ambient pressure, yet produces very dense MgB2 with little loss of stoichiometry. Such a technique can be useful for rapid and reliable compound syntheses and characterizations for future discovery of new or improved superconductors with higher Tc, higher Hc2 or improved flux pinning characteristics. We also show that while inherently weak-link-free, the nature of the material is such that the grain boundaries of the polycrystalline MgB2 can easily be altered to exhibit induced weak-link behavior with accompanying loss in critical current density by orders of magnitude.

International Journal of Wireless & Mobile Networks , 2012,
Abstract: As the various architectures and protocol have been implemented a true VoD system has great demand in the global users. The traditional VoD system does not provide the needs and demands of the global users. The major problem in the traditional VoD system is serving of video stream among clients is duplicated and streamed to the different clients, which consumes more server bandwidth and the client uplink bandwidth is not utilized and the performance of the system degrades. Our objective in this paper is to send one server stream sufficient to serve the many clients without duplicating the server stream. Hence we have proposed a protocol and algorithm that chains the proxy servers and subscribed clients utilize client’s uplink bandwidth such that the load on the server is reduced. We have also proved that less rejection ratio of the clients and better utilization of the buffer and bandwidth for the entire VoD system.
Enhanced photocurrent in solution processed electronically coupled CdSe nanocrystals thin films

Physics , 2015, DOI: 10.1063/1.4822094
Abstract: We have demonstrated the fabrication of highly continuous and smooth CdSe semiconductor films containing self-assembled nanocrystals (NCs) using a simple, low cost solution-processed deposition technique. The impact of thermal annealing and ethanedithiol (EDT) treatment on oleate capped CdSe NCs films is illustrated. Post deposition EDT treatment enhances strong electron coupling between NCs by reducing the inter-particle distance, which enhances four orders of magnitude of photocurrent in the pn-device. Mild thermal annealing of NC films cause large redshift and significant broadening. Our findings suggest that NCs with short-range organic ligands are suitable for high-performance Thin-Film-Transistors and next generation high-efficiency photovoltaics.

Abstract: Solid-state fermentation (SSF) holds tremendous potentials for the production of industrially significant enzymes. The present study describes the production of lipase by a novel rumen bacterium, Pseudomonas sp. strain BUP6 on agro-industrial residues. Pseudomonas sp. strain BUP6 showed higher lipase production when grown in Basal salt medium (BSM) supplemented with oil cakes. Initially, five different oil cakes (obtained after extracting oil from coconut, groundnut, cotton seed, gingelly or soybean) were screened to find out the most suitable substrate-cum-inducer for the production of lipase. Among them, groundnut cake supported the maximum production of lipase (107.44 U/gds). Box-Behnken Design (BBD), followed by response surface methodology (RSM) was employed to optimize the culture parameters for maximizing the production of lipase. Using the software Minitab 14, four different parameters like temperature, pH, moisture content and incubation time were selected for the statistical optimization, which resulted in 0.7 fold increase (i.e., 180.75 U/gds) in production of lipase under the optimum culture conditions (temperature 28°C, pH 5.9, moisture 33% and incubation 2 d). Thus, this study signifies the importance of SSF for the production of industrially-significant lipase using agro-industrial residues as solid support.
