The phaseinformation obtained from cross phase spectrum using 2D DFT(Discrete Fourier Transform) of images contains importantinformation of image point similarity and dissimilarity. Level by levelblock matching using phase only correlation i.e. phase basedcorrespondence search is used to find the correspondence pointbetween input image and registered image using image declivity.Image registration is automatic, very fast, self adaptive segmentationtechnique as compare to other segmentation technique. I proposedreference point selection method based on image declivity which usedfor block matching and numbers of references point generated byimage declivity is controlled according to application. Thephase-based image matching is successfully applied to registeredimage for obstacle detection tasks for computer vision applications.

Complete Local Binary Pattern method is an extended version of Local Binary Pattern method with a little difference. LBP feature considers only signs of local differences, whereas CLBP feature considers both signs and magnitude of local differences as well as original center gray level value. CLBP and LBP have same computational complexity while CLBP performs better facial expression recognition over LBP using SVM training and multiclass classification with binary SVM classifiers. The experimental result demonstrate the average efficiency of recognition of propose method (35 images) with CLBP is 86.4%, while with LBP and CCV is 84.1255% and 75.83% in the JAFFE database.

There are a certain features of these types of skin cancers, which can be extracted using proper feature extraction algorithm. The features of skin lesions are extracted normalized symmetrical Grey Level Co-occurrence Matrices (GLCM).GLCM based texture features are extracted from each of the four classes and given as input to the Multi-Class Support vector machine which is used for c1assification purpose. It c1assifies the given data set into one of the four skin cancer classes. The accuracy of our proposed method is 81.43%.

The mechanism by which heat shock is sensed and the signals that trigger heat shock response remain an enigma. We aim to determine the role of guanine-nucleotide binding proteins (G)-proteins in mediating heat shock response in eukaryotic cells. The effect of heat shock on high affinity GTPase activity in presence or absence of modulators of G-proteins, such as pertussis toxin was studied by measuring GTPase catalyzed release of 32[Pi] from gamma-32[P]GTP. The effect of pertussis toxin on induction of heat shock proteins in cells subjected to thermal stress was studied by SDS-PAGE analysis of 35[S]-methionine labelled cellular proteins. Exposure of cultured human malignant cells to thermal stress (43 degrees C) resulted in a significant increase in activity of high affinity GTPase in the membranes (P < 0.001). This response to heat shock was inhibited by prior exposure of the cells to nanogram concentrations of pertussis toxin, suggesting the involvement of G-proteins in mediating heat shock response. To characterize this G-protein dependence further, we assayed thermal stress stimulated high affinity GTPase activity in cells pretreated with antisera (AS/7) raised against a synthetic peptide corresponding to the last 10 amino acids of alpha-subunit of inhibitory G-protein (Gi). A partial reduction in heat shock induced stimulation of GTPase activity was observed in the presence of this antisera. The pertussis toxin treated cells did not show induction of heat shock proteins in response to thermal stress.(ABSTRACT TRUNCATED AT 250 WORDS)

It encodes for MrdH, a predicted protein of ∼40 kDa with a chimeric domain organization derived from the RcnA and RND (for resistance-nodulation-cell division) metal efflux proteins. The metal resistance function of mrdH was identified by the ability to confer nickel resistance upon its complementation into rcnA mutant (a nickel- and cobalt-sensitive mutant) of Escherichia coli . However, the disruption of mrdH in P. putida resulted in an increased sensitivity to cadmium and zinc apart from nickel. Expression studies using quantitative reverse transcription-PCR showed the induction of mrdH by cadmium, nickel, zinc, and cobalt. In association with mrdH , we also identified a conserved hypothetical gene mreA whose encoded protein showed significant homology to NreA and NreA-like proteins. Expression of the mre...

In view of the unavoidable use of MW emitting devices (microwaves oven, mobile phones, Wi-Fi, etc.) and their harmful effects on biological system, it was thought worthwhile to investigate the long-term effects of low-level MW irradiation on the reproductive function of male Swiss strain mice and its mechanism of action. Twelve-week-old mice were exposed to non-thermal low-level 2.45-GHz MW radiation (CW for 2 h/day for 30 days, power density = 0.029812 mW/cm(2) and SAR = 0.018 W/Kg). Sperm count and sperm viability test were done as well as vital organs were processed to study different stress parameters. Plasma was used for testosterone and testis for 3β HSD assay. Immunohistochemistry of 3β HSD and nitric oxide synthase (i-NOS) was also performed in testis. We observed that MW irradiation induced a significant decrease in sperm count and sperm viability along with the decrease in seminiferous tubule diameter and degeneration of seminiferous tubules. Reduction in testicular 3β HSD activity and plasma testosterone levels was also noted in the exposed group of mice. Increased expression of testicular i-NOS was observed in the MW-irradiated group of mice. Further, these adverse reproductive effects suggest that chronic exposure to nonionizing MW radiation may lead to infertility via free radical species-mediated pathway.

Fuel cells are used to supply the power to the drive. Li-ion battery is also used to supply additional power required in transient states. The drive is tested under motoring as well as regenerative operating conditions. PID controller is used in a speed control loop for better control. Complete model of the drive is modeled in MATLAB/Simulink Software. The hybrid sources are connected through a DC–DC bidirectional converter connected with a VSI.
