Ten isolates of Colletotrichum capsici causing chilli anthracnose were collected from 10 provinces in the northeast of Thailand. The isolates were evaluated for their morphological and cultural characteristics, pathogenic variability on chilli fruits and genetic characterization using random amplified polymorphic DNA (RAPD-PCR). Based on the morphological traits and cultural characteristics of the C. capsici populations, 10 isolates were categorized into six groups. These were designated, respectively, as CC-I, CC-II, CC-III, CC-IV, CC-V and CC-VI. In Potato Dextrose Agar culture, most of the isolates produced cottony colonies. However, differences were obtained in colony color, shape and size of conidia. Based on the effect of carbendazim, 10 isolates were classified into two groups designated as highly resistant group (<40% inhibition) and highly sensitive group (>90% inhibition). Three virulence degrees of 10 isolates on chilli fruits were evaluated. Molecular polymorphism generated by RAPD confirmed the variation of the different isolates and they were grouped into two clusters. However, morphological, pathological and RAPD grouping of isolates suggested no correlation among the test isolates.

In this approach three variables root mean square, standard deviation & variance were selected for the analysis. These three parameters gave best results for discriminating hand movements from time domain analysis using SEMG. As the frequency range of SEMG signal is specified to be from 0 Hz to 400 Hz, therefore the analysis was divided into three sections of frequencies as: low(<60Hz), high pass (>250Hz) and band pass (70-250Hz). This is done to establish the frequency change in the three regions for specified selected output. The three parameters were used as input variables to fuzzy logic controller for discrimination of the hand movements i.e. whether the hand is closed or open. SEMG signal was taken from below elbow position using bipolar electrodes as this part was found to be more active during expansion and contraction of muscles. Out of the three parameters standard deviation gave best results for discriminating hand movements (opening and closing). Out of three filters, low pass filter gave the best results for discriminating opening and closing movements. Further, to develop precise control of the grip prosthetic, the work is extended to multilevel SEMG control. A gripexerciser was used to calibrate the executed force and SEMG signal. The result was a fuzzy logic controller for the accurate grip force.

The antibacterial activity of Paederia foetida against few clinical isolates of H. pylori in vitro was examined. The MIC of P. foetida is µg/ml, showing its effectiveness in inhibiting H. pylori growth in vitro irrespective of the genetic makeup of the strains. This study provides novel insights into the therapeutic effect of P. foetida against H. pylori infection, suggesting its potential as an alternative therapy, and opens the way for further studies on identification of novel antimicrobial targets of P. foetida.

LytM was identified as the only autolysin in a previously reported autolysis-deficient (lyt − ) strain of Staphylococcus aureus. Purified LytM has been studied in great detail for its lytic properties and its production is elevated in vancomycin resistant S. aureus. However, the postulated roles of LytM in S. aureus are largely speculative. Studies utilizing a reporter strain where the lytM promoter was cloned in front of a promoterless lacZ gene and fused in S. aureus strain SH1000 suggest that the expression of lytM is highest during the early exponential phase. Additionally, lytM expression was down-regulated in agr − mutants. Expression of lytM was not affected by the presence of cell wall inhibitors in the growth medium. To further determine the significance of LytM in staphylococcal autolysis, the gene encoding LytM was deleted by site directed mutagenesis. Deletion of lytM, however, did not alter the rate of staphylococcal cell autolysis. Surprisingly, when the lytM mutation was combined with the lyt − mutant, the lytic activity band of the lyt − strain was still apparent in the lytM:lyt − double mutant. Purified full-length His-tagged LytM did not demonstrate any lytic activity against S. aureus cells. Surprisingly, cultures of S. aureus lytM deletion mutant lysed at a significantly faster rate compared to the wild-type S. aureus in the presence of oxacillin. Findings of this study raise questions about LytM as an autolysin and the significance of this protein should thus be investigated beyond its role as an autolysin.

The physical and spectral data of synthesized compounds are determined. The synthesized compounds have been screened for their anti-convulsant activity by MES method.

Most distributed applications and services were designed with the assumption that the terminals were powerful, stationary and connected to fixed networks. One of the biggest challenges in future application development is device heterogeneity. In the future, we expect to see a rich variety of computing devices that can run applications. These devices have different capabilities in processors, memory, networking, screen sizes, input methods, and software libraries. We also expect that future users are likely to own many types of devices. Depending on users changing situations and environments, they may choose to switch from one type of device to another that brings the best combination of application functionality and device mobility. Applications, middleware, and systems can be measured in a variety of dimensions, including usability, distributability, integration, conformance to standards, extensibility, internationalizability, manageability, performance, portability, scalability reliability-fault tolerance and security. We call these pervasive attributes, since they can apply to the system as a whole, not just to the system's components. In this paper we have designed and implemented a secure and reliable application framework called the Platform for Device and Computation Management (PDCM) system that can both assist developers to build multi-platform applications that can run on heterogeneous devices and allow a user to move/migrate a running application among heterogeneous devices.

Dielectric constant and shielding effectiveness due to absorption (SE A ) were calculated using S-parameter obtained from the vector network analyzer in 8.2-12.4 GHz frequency range. Maximum SE A of 26 dB (>99%) was achieved for polymer sample. The real part e 0 of complex permittivity shows small variation, whereas the imaginary part e 00 is found to decrease with the increase in frequency. Different formulations have been performed to see the effect of monomer to dopant ratio on intrinsic properties of polyaniline. Further characterization of polymer was carried out by UV-visible and thermal gravimetric analysis, whereas the conductivity measurements were carried out by the four-probe method.
