The objective is to design and implement both symmetric key and public key algorithms of a cryptographic on chip level and make better architecture with pleasing performance. Crypto-processor design, have been designed with unified field instructions to make different processor architecture and improve system performance. The proposed high speed Montgomery modular multiplication and high radix Montgomery multiplication algorithms for pairing computation supports the public key algorithm. This design has been developed using Verilog HDL’s and verified using ModelSim-Altera 6.4a, and it has synthesized with Xilinx 9.1 Integrated Synthesis Environment (ISE) tool

INFLUENCE OF FOOT TYPE ON BALANCE AND POSTURAL SWAY AMONG THE COMMUNITY DWELLING OLDER ADULTSâ€

Aim: To compare the relationship between Foot Type, Postural sway and Balance among the community dwelling older adult.Objective:  1. To find the correlation between foot type on static and dynamic balance among community dwelling older adults2.To find the correlation between postural sway and foot type among community dwelling older adults.Methodology: 20 community dwelling older adults were included for the study based on inclusion and exclusion criteria. The subjects foot type was assessed using the navicular drop test. The subjects were classified into 3 different foot types: as pronated, neutral and supinated. After classifying the subject according to the foot type, they were measured for static and dynamic balance using Berg Balance Scale(BBS). For the same subjects, postural sway was assessed with Lord's Sway meter under 4 situations: 1. Standing on stable surface(floor) open eyes and 2. Standing on stable surface(floor) closed eyes, 3. Standing on unstable surface(foam) with eyes open and 4. Standing on unstable surface(foam) with eyes closed. The sway of older adult was recorded and analysedResult: There was strong correlation between pronated and anteroposterior sway in EO on unstable surface and between neutral and anteroposterior sway in EC standing on stable surface. There was moderate correlation between berg balance scale score and neutral foot type. Pronated and anteroposterior sway in EO standing on stable surface also showed moderate correlation.Conclusion: The results showed strong to moderate correlation between foot type, postural sway and balance, from this study it is clear that foot position affects the balance among older adults.  Â

Total organic carbon profile in water and sediment in coral reef ecosystem of Agatti Island, Lakshadweep Sea

936-942Total organic carbon profile in sea water (depth-wise) and sediment has been investigated on seasonal basis in the coral reef ecosystem of Agatti island, Lakshadweep sea. The TOC values of sea water and sediment were converted into percentage to understand its level of distribution. The level of TOC in the surface sea water ranged from 0.40 to 1.02 ppm and the level of TOC at the ~5 m depth ranged from 0.18 to 1.86 ppm. The pH did not show any variation depth-wise (7.65 to 8.49). Sedimentary organic carbon (SOC) was found in the range of 0.21 to 2.35 mg C/g. Significant seasonal variation was not found for water TOC and SOC levels. The pH for sediment was recorded from 7.79 to 8.62. Water pH showed significant positive correlation with sediment pH (R2=0.959). The sand fraction was found more in the texture followed by silt and clay. Clay was found to have positive correlation with SOC (P >0.01). The TOC profile in the Lakshadweep sea was found in the order: Surface water TOC < water TOC at ~5 m depth < SOC. The percentage composition of SOC showed more than 1000 times as compared to water TOC. However, the levels recorded in this study are found within the limit prescribed by EPA and its influence on coral reef ecosystem is discussed

Usefulness of preoperative high resolution computed tomography in middle ear cholesteatoma.

Cholesteatoma is traditionally diagnosed by otoscopic examination and treated by explorative surgery. The need for imaging in an uncomplicated case is contentious. This study assesses the usefulness of a pre-operative high-resolution CT scan in depicting the status of the middle ear structures in the presence of cholesteatoma. Cholesteatoma is a sac of keratinising squamous epithelium in the middle ear cleft. The lesion is classically recognised by the presence of attic squames on otoscopic examination. The presence of cholesteatoma must also be suspected beneath polyps protruding from the pars flaccida or when there is a marginal tympanic membrane perforation or granulation. Cholesteatoma is a potentially serious condition as it can progressively enlarge and erode into neighbouring structures, giving rise to serious intracranial and extracranial complications. The patient is benefited as he has pre surgical assessment rather wait for results of surgical exploration. Forewarned about complications. The patient has a pictorial depiction of his disease and understands the need for surgical intervention and difficulty in hearing preservation. The surgeon is armed with a visual aid to preoperative counseling ,spatial orientation of disease extent and identifies problem areas prior to surgery

Development and validation of integrated pest management modules against spotted pod borer Maruca vitrata Fabricius on garden bean Lablab purpureus var. typicus (L.)

To reduce the detrimental effect of insecticides, an effective Integrated Pest Management (IPM) module is necessary for the eco-friendly management of Maruca vitrata in garden bean ecosystem. Two field trials were carried out to evaluate the efficacy of different insecticides and botanicals against M. vitrata on Lablab purpureus var. typicus. Two seasons field evaluation of insecticides revealed that chlorantraniliprole 18.5 SC  was the most effective treatment to control the pest recorded 0.11 and 0.36 larva/plant in two seasons, respectively after two rounds of spray followed by flubendiamide 20 WG (0.46 and 0.92 larva/ plant) and emamectin benzoate 5 SG (0.50 and 0.95 larva/plant). Among botanicals tested, commercial neem formulation and 5% Ageratina adenophora recorded the least larval count of 1.64 &amp; 1.05 larva/plant and 2.24 &amp; 1.45 larva/plant in two seasons, respectively. IPM modules were developed with three effective insecticides (chlorantraniliprole 18.5 SC, flubendiamide 20 WG and emamectin benzoate 5 SG), two effective botanicals (commercial neem formulation 1500 ppm and 5% A. adenophora) along with the pheromone trap for validation. All the IPM modules were equally effective in managing M. vitrata population on L. purpureus and recorded a significantly (at 5 %) lower larval population than the farmer’s practice. The residues of chlorantraniliprole, flubendiamide and emamectin benzoate reached below the detectable level at the time of harvest. The population reduction of predatory coccinellids and spiders was also lower in IPM modules than in farmer’s practice. An increased benefit cost (1.95 to 1.99) ratio was observed in IPM modules. 

Design of Multifunctional Lattice‐Frame Materials for Compact Heat Exchangers

Structured porous materials show great potential as extended surfaces in heat-exchange applications that also require design for load-bearing capability. In particular, lattice-frame materials (LFM) are known for their superior strength-to-weight ratio; this work presents a comprehensive experimental and numerical study of fluid flow and heat transfer in porous LFMs. Flow through a periodic unit cell of the material is simulated to characterize the forced-convection performance under hydraulically and thermally fully developed conditions. The performance of LFMs with a tetrahedral ligament configuration is characterized as a function of Reynolds number in the laminar regime (150 \u3c Re \u3c 1000) in terms of Nusselt number and friction factor; the effect of porosity is studied by changing the ligament diameter. Experiments are performed for a subset of porosities to validate the numerical approach. A method is demonstrated for utilizing the simulation results, which assume perfect surface efficiency, to predict the performance of LFMs with non-ideal surface efficiency, based on the conduction resistance of the ligaments. It is shown that the thermal behavior of the ligaments closely matches that of cylindrical fins in cross flow and that this analogy can be used to calculate the overall surface efficiency. The implications of the current results on the design of compact heat exchangers using LFMs is assessed using several conventional performance metrics. Our analysis illustrates the challenges in defining any one universal performance metric for compact heat exchanger design; an appropriate performance metric must be selected that accounts for the particular multifunctional performance characteristics of interest. LFMs are shown to provide the benefits of high-porosity and high surface area-to-volume ratio of materials such as metal foams, while also incurring lower pressure drops and displaying higher structural integrity. This makes them ideal for heat exchangers in aerospace and other applications demanding such multifunctional capabilities. The characterization provided in this study readily allows LFM designs for heat exchanger applications with combined heat-transfer and pressure-drop constraints

Cloning of partial putative gonadotropin hormone receptor sequence from fish

A search for the presence of mariner-like elements in the Labeo rohita genome by polymerase chain reaction led to the amplification of a partial DNA sequence coding for a putative transmembrane domain of gonadotropin hormone receptor. The amplified DNA sequence shows a high degree of homology to the available turkey and human luteinizing and follicle stimulating hormone receptor coding sequences. This is the first report on cloning such sequences of piscine origin
