Whale Optimization Algorithm and Blockchain Technology for Intelligent Networks
Sulthana, Shazia,Reddy, BN Manjunatha International Journal of Computer ScienceNetwork S 2022 International journal of computer science and netw Vol.22 No.7
The proposed privacy preserving scheme has identified the drawbacks of existing schemes in Vehicular Networks. This prototype enhances the number of nodes by decreasing the cluster size. This algorithm is integrated with the whale optimization algorithm and Block Chain Technology. A set of results are done through the NS-2 simulator in the direction to check the effectiveness of proposed algorithm. The proposed method shows better results than with the existing techniques in terms of Delay, Drop, Delivery ratio, Overhead, throughout under the denial of attack.

In the present communication, pure and stable a-Bismuth Oxide (Bi2O3) nanoparticles (NPs) weresynthesized by low temperature solution combustion method using urea as a fuel and calcined at 500oC. The synthesized sample was characterized by using powder X-ray Diffraction (PXRD), Scanning ElectronMicroscopy (SEM), Energy dispersive X-ray analysis (EDAX), Transmission Electron Microscopy (TEM),Fourier Transform Infrared Spectroscopy (FTIR) and UVeVisible absorption spectroscopy. The PXRDpattern confirms the formation of mono-clinic, stable and low temperature phase a-Bi2O3. The directoptical energy band gap was estimated by usingWood and Tauc's relation which was found to be 2.81 eV. The characterized sample was studied for X-ray/gamma ray shielding properties in the energy range0.081e1.332 MeV using NaI (Tl) detector and multi channel analyzer (MCA). The measured shieldingparameters agrees well with the theory, whereas, slight deviation up to 20% is observed below 356 keV. This deviation is mainly due to the influence of atomic size of the target medium. Furthermore an accuratetheory is necessary to explain the interaction of X-ray/gamma ray with the NPs.The present workopens new window to use this facile, economical, efficient, low temperature method to synthesizenanomaterials for X-ray/gamma ray shielding purpose

Expression and lytic efficacy assessment of the Staphylococcus aureus phage SA4 lysin gene
Anil Kumar Mishra,Manjunatha Reddy,Konasagara Nagaleekar Viswas,Abhishek,Sujeet Kumar,Mayank Rawat 대한수의학회 2013 Journal of Veterinary Science Vol.14 No.1
Treatment of bovine mastitis caused by Staphylococcus (S.)aureus is becoming very difficult due to the emergence of multidrug-resistant strains. Hence, the search for novel therapeutic alternatives has become of great importance. Consequently, bacteriophages and their endolysins have been identified as potential therapeutic alternatives to antibiotic therapy against S. aureus. In the present study, the gene encoding lysin (LysSA4) in S. aureus phage SA4 was cloned and the nucleotide sequence was determined. Sequence analysis of the recombinant clone revealed a single 802-bp open reading frame encoding a partial protein with a calculated mass of 30kDa. Results of this analysis also indicated that the LysSA4sequence shared a high homology with endolysin of the GH15phage and other reported phages. The LysSA4 gene of the SA4phage was subsequently expressed in Escherichia coli. Recombinant LysSA4 induced the lysis of host bacteria in a spot inoculation test, indicating that the protein was expressed and functionally active. Furthermore, recombinant lysin was found to have lytic activity, albeit a low level, against mastitogenic Staphylococcus isolates of bovine origin. Data from the current study can be used to develop therapeutic tools for treating diseases caused by drug-resistant S. aureus strains.

Ensemble Modulation Pattern based Paddy Crop Assist for Atmospheric Data
Sampath Kumar, S.,Manjunatha Reddy, B.N.,Nataraju, M. International Journal of Computer ScienceNetwork S 2022 International journal of computer science and netw Vol.22 No.9
Classification and analysis are improved factors for the realtime automation system. In the field of agriculture, the cultivation of different paddy crop depends on the atmosphere and the soil nature. We need to analyze the moisture level in the area to predict the type of paddy that can be cultivated. For this process, Ensemble Modulation Pattern system and Block Probability Neural Network based classification models are used to analyze the moisture and temperature of land area. The dataset consists of the collections of moisture and temperature at various data samples for a land. The Ensemble Modulation Pattern based feature analysis method, the extract of the moisture and temperature in various day patterns are analyzed and framed as the pattern for given dataset. Then from that, an improved neural network architecture based on the block probability analysis are used to classify the data pattern to predict the class of paddy crop according to the features of dataset. From that classification result, the measurement of data represents the type of paddy according to the weather condition and other features. This type of classification model assists where to plant the crop and also prevents the damage to crop due to the excess of water or excess of temperature. The result analysis presents the comparison result of proposed work with the other state-of-art methods of data classification.

For the first time Aluminium-BariumeZinc oxide nanocomposite (ZABONC) was synthesized by solution combustion method where calcination was carried out at low temperatures (6000 C) to study the electromagnetic (EM) (X/g) radiation shielding properties. Further for characterization purpose standard techniques like PXRD, SEM, UV-VISIBLE, FTIR were used to find phase purity, functional groups, surface morphology, and to do structural analysis and energy band gap determination. The PXRD pattern shows (hkl) planes corresponding to spinel cubic phase of ZnAl2O4, cubic BaðNO3Þ2, a and g phase of Al2O3 which clearly confirms the formation of complex nano composite. From SEM histogram mean size of nano particles was calculated and is in the order of 17 nm. Wood and Tauc’s relation direct energy band gap calculation gives energy gap of 2.9 eV. In addition, EM (X/g) shielding properties were measured and compared with the theoretical ones using standard procedures (NaI (Tl) detector and multi channel analyzer MCA). For energy above 356 keV the measured shielding parameters agree well with the theory, while below this value slight deviation is observed, due to the influence of atomic/crystallite size of the ZABONC. Hence synthesized ZABONC can be used as a shielding material in EM (X/g) radiation shielding
