Objective: To study the antimicrobial activity of the ethanolic extract and its various fractions of Cleome rutidosperma DC. Materials and methods : Minimum inhibitory concentration of the extract was performed by broth dilution method against both for the bacterial and fungal strains. Results : The results of MIC study revealed the antimicrobial activity of the ethanolic extract and its different fractions against the tested strains of microorganisms. The activities were found to be potentiated by fractionation of mother extract (ethanolic extract) with highest activity for diethyl ether fraction. Conclusion : The present study indicates the potential usefulness of C. rutidosperma in the treatment of various pathogenic diseases.Keywords

Glucocorticoids (GC) are usually considered to be immunosuppressive and antiinflammatory. However, recent studies in mammals have demonstrated the differential effects of GC on non-specific host-defense mechanism, depending on dose or duration of treatment. Although the influence of GC on specific immunity has been studied in a number of reptilian species, no attempt is made to understand the role of GC in modulation of non-specific immune responses. In view of this, the present study is designed to observe in vitro dose and time-related effects of glucocorticoid, hydrocortisone (HC) on phagocytosis and nitrite production by LPSinduced splenic macrophages (mq) in wall lizard Hemidactylus flaviviridis.

This paper aims to report on prioritisation of developmental activities carried out by those non-governmental organisations (NGOs) which are working for all round development of Nagaland, India. In this study, 120 employees of 45 identified NGOs of Nagaland, India, were included and considered as respondents. Five developmental activities were identified and presented in ten possible pairs (combinations) to the respondents and they were asked to select one over the other from each pair separately, which were considered more preferable from their point of view. After that, method of Paired Comparisons was followed to establish the hierarchy of developmental activities. As per scale value, development of 'health' sector is the highly preferred activity, 'education' is the second preferred and 'development of livestock' is the least preferred activity.Full Text

ZnS nanobelts and ZnS@reduced graphene oxide (rGO) nanocomposites were synthesized via simple solvothermal treatments. The chemical composition, structure and optical properties of ZnS nanobelts and ZnS@rGO nanocomposites samples were characterized by X-ray diffraction (XRD),Raman Spectroscopy and FESEM, UV-visible spectroscopy. We have used UV-Visible absorption spectra to find the optical band gap of prepared ZnS nanobelts and ZnS@rGO nanocomposites, direct bandgap of pure ZnS is 2.70 eV and that in case of ZnS@rGO is about 2.59 eV. The bandgap of pure ZnS nanostructure differ significantly from bulk ZnS due to the quantum confinement effect in nanostructure. ZnS nanostructure and ZnS@rGO nanocomposites were used as a photocatalyst for the degradation of methylene blue (MB) under visible light irradiation.Keywords

Axle counter, which is an integral part of signaling systems, plays an important role to control the train movement. This paper aims to analyze its performance on the basis of its failure incidents. In this context, failure data points of axle counter from a station of Kolkata metro railway has been collected for a period of 15 months. The overall equipment effectiveness (OEE) based on availability, performance and quality has been calculated for each of these 15 months. It is observed that mean of OEE is around 75% and variation is 10% approximately.References

In this article, we discuss the potential of airborne hyperspectral data in mapping host rocks of mineral deposits and surface signatures of mineralization using AVIRIS-NG data of a few important geological provinces in India. We present the initial results from the study sites covering parts of northwest India, as well as the Sittampundi Layered Complex (SLC) of Tamil Nadu and the Wajrakarur Kimberlite Field (WKF) of Andhra Pradesh from southern India. Modified spectral summary parameters, originally designed for MRO-CRISM data analysis, have been implemented on AVIRIS-NG mosaic of Jahazpur, Rajasthan for the automatic detection of phyllosilicates, carbonates and Fe–Mg-silicates. Spectral analysis over Ambaji and the surrounding areas indicates the presence of calcite across much of the study area with kaolinite occurring as well in the north and east of the study area. The deepest absorption features at around 2.20 and 2.32 μm and integrated band depth were used to identify and map the spatial distribution of phyllosilicates and carbonates. Suitable thresholds of band depths were applied to map prospective zones for marble exploration. The data over SLC showed potential of AVIRIS-NG hyperspectral data in detecting mafic cumulates and chromitites. We also have demonstrated the potential of AVIRIS-NG data in detecting kimberlite pipe exposures in parts of WKF.Keywords
