<P>Strain DCY24(T), a Gram-reaction-positive, aerobic, rod-shaped, motile bacterium, was isolated from soil of a ginseng field in South Korea. According to 16S rRNA gene sequence analysis, it was closely related to Nocardioides aromaticivorans DSM 15131(T) (95.1 % similarity), Nocardioides simplex KCTC 9106(T) (95.0 %), Nocardioides nitrophenolicus DSM 15529(T) (94.8 %) and Nocardioides kongjuensis DSM 19082(T) (94.7 %). Chemotaxonomic data revealed that strain DCY24(T) possessed MK-8(H(4)) as the predominant menaquinone, ll-2,6-diaminopimelic acid as the diagnostic diamino acid, phosphatidylglycerol and diphosphatidylglycerol as predominant polar lipids and iso-C(16 : 0), iso-C(17 : 0) and C(18 : 1)omega9c as predominant fatty acids. The DNA G+C content was 71.0 mol%. Based on evidence from this polyphasic study, strain DCY24(T) (=KCTC 19265(T) =LMG 24128(T)) should be classified as the type strain of a novel Nocardioides species, for which the name Nocardioides humi sp. nov. is proposed.</P>
Spirosoma radiotolerans is a Gram-negative, short rod-shaped and gamma-radiation-resistant bacterium isolated from rice field in South Korea (GPS; 37<SUP>o</SUP>34'30''N, 127<SUP>o</SUP>00'30''E). The complete genome of S. radiotolerans consists of a chromosome (7,029,352bp). From the genome sequence database, we have identified the cluster of genes responsible for DNA recovery from ionizing radiation. The key enzymes for the nucleotide excision repair (NER) were investigated and were identified, suggesting that S. radiotolerans DG5A use (NER) pathways for efficient removal of pyrimidine dimers which are the most abundant type of UV-induced damage. Complete genome information enables further studies on the DNA repair mechanisms during the ionizing radiation.
The Cryptographic systems need a secret key or a random number must be necessarily tied to an individual through a unique identifier. This unique identifier definitely might exist a globally user id or biometric data . In this paper we combined biometric with cryptography in which the intensity of each pixel of iris is changed into the elliptic curve and encrypted using ECC. The receiver end original image is recovered by using their decryption and authentication  is performed using ECDSA. The proposed technique is implemented for BMP images. We can enroll and add the number of images for authentication .It has been also performed more security if the image is recovered without being any side channel attack.
The in-situ measurement of dilution during the laser surface alloying process is an enormously difficult task, due to the localized nature of laser energy and very short laser-material interaction time. Therefore, a computational approach (finite-element method and analysis of variance) was effectively employed to evaluate the dilution during the laser surface alloying process. Firstly, a finiteelement model based on COMSOL™ multiphysics was developed to predict the dilution of Mo with Al during non-equilibrium laser surface alloying process. Secondly, the optimization model based on Design-Expert® was developed to find the optimal laser surface alloying parameters (laser power, scanning speed, and fill spacing) to obtain a microstructure suitable for improved corrosion resistance that is primarily attributed to the formation of Al5Mo intermetallic phase (16.7 at% Mo). The present optimization model utilized the prior experimental and computational (finite-element) modeling data for the concentration of Mo (at%). The optimization analyses were carried out for the all the current datasets and the analysis revealed 44 optimal solutions that indicate the highest desirability. The confirmation runs were carried out to validate the optimization model. The experimental observation showed that the sample processed with optimal processing conditions demonstrates good corrosion resistance.
