Recognition of plants has become an active area of research as most of the plant species are at the risk of extinction. This paper uses an efficient machine learning approach for the classification purpose. This proposed approach consists of three phases such as preprocessing, feature extraction and classification. The preprocessing phase involves a typical image processing steps such as transforming to gray scale and boundary enhancement. The feature extraction phase derives the common DMF from five fundamental features. The main contribution of this approach is the Support Vector Machine (SVM) classification for efficient leaf recognition. 12 leaf features which are extracted and orthogonalized into 5 principal variables are given as input vector to the SVM. Classifier tested with flavia dataset and a real dataset and compared with k-NN approach, the proposed approach produces very high accuracy and takes very less execution time. © 2012 IEEE. Source

Egg-laying hens were immunized with the Echis carinatus venom and the resulting antibodies were extracted from egg yolk by four different purification methods. The chicken egg yolk antibodies were purified by the water dilution method, polyethylene glycol (PEG) and ammonium sulphate precipitation method, chloroform extraction and the Lithium sulphate precipitation method. These methods were compared in terms of total protein content, immunospecific anti E. carinatus immunoglobulin Y (IgY) activity and in vitro and in vivo neutralizing capacity of IgY against the E. carinatus venom. Total IgY concentrations varied from 1.6 to 7.0 mg per ml of egg yolk. In neutralization studies, IgY purified by PEG and ammonium sulphate precipitation (PEG-AS) showed better results when compared to other purification methods. Approximately 1.25 mg of IgY (PEG-AS) was able to neutralize 2Lethal Dose50 of the E. carinatus venom. Purification of IgY by PEG and ammonium sulphate yielded very pure IgY at high quantities (93% ± 5% of total egg yolk protein), which was also capable of neutralizing toxic and lethal components of the E. carinatus venom.

Feather keratin is highly resistant to degradation, but some keratinase producing microorganisms can easily degrade these insoluble keratins. These keratinase producing species have an important application in removal of poultry waste and recycled into valuable byproduct. A feather-degrading bacterium with high keratinase activity was isolated and identified as Bacillus megaterium (A1). The selected organism showed keratinase activity of 72.875 IU/mg and the protein content of 4 mg/ml. Maximum enzyme production was observed on 96 hr. The intense feather degrading was achieved in 35°C and initial pH adjusted to 7.5. Among the extra nitrogen or carbon sources used, significant improvement in yield of keratinase was obtained when grown in medium containing 2% feather meal. The protein profile was analyzed in SDS-PAGE showed multiple bands. Zymography analysis showed a single band with molecular weight of 46 KDa which corresponds to keratinase activity. Immobilized cells of B. megaterium (A1) had highest durability to degrade feather keratin. Fourier Transform Infrared Spectroscopy (FTIR) showed that the change in the functional group was catalyzed by the unique enzymes of B. megaterium (A1). From this study, Bacillus megaterium isolated from feather dumped soil can be used as a potential candidate for degradation of feather and for can be used as additives in poultry field. Source

The multimedia content protection has become a boon for an IT industry nowadays. This scheme is based on layered encryption/decryption involving biometric authentication. Utilization of fingerprints as keys in encryption/decryption procedures eliminates the feasibility of illegal key sharing, which hampers the content protection schemes based solely on traditional keys. The computation times required for the necessary encryption and decryption processes are provided for AES symmetric-key system and HECC asymmetric-key system. These times show the applicability of the method. Utilization of widely available encryption/decryption systems (e.g., AES and HECC) increases the applicability even further. Custom hardware chips will reduce these times in future applications. © 2006-2015 Asian Research Publishing Network (ARPN). Source

Cancer research is the intense scientific effort to understand disease processes and discover possible therapies. Breast cancer is the second most common type of cancer after lung cancer. Normal breast cells and most breast cancer cells have receptors that attach to circulating estrogen and progesterone. In the present study, cha-rasprotein and cytochrome P450 was docked with the two drugs and the energy value obtained for limonene (-6.07762 kcal/mol) with elapsing time of 5 seconds, Eugenol (-6.53482 kcal/mol) with elapsing time of 7 seconds, using Argus lab docking software.
