A new species of Nervilia Gaud. Nervilia gleadowii Nageswara Rao from Tehri Garhwal, U.P. is described. This species is allied to Nervilia scottii/I> (Rchb.f.) Schltr. but differs in having the flowers erect and close together, the bracts erect and the lip with glabrous disc and oblong- elliptic midlobe. The specific epithet is named after Mr. F. Gleadow who collected the plant for the first time from Tehri Garwal in 1900.- Teratological Observations in some Orchids of Arunachal Pradesh

Batch experiments are carried out for the adsorption of direct yellow 17, reactive blue 4 and rhodamine B dyes by Sorel's cement. The operating variables studied are initial dye concentration (Ci), pH, temperature and contact time. The equilibrium data are fitted to the Langmuir isotherm equations and the adsorption efficiency, adsorption capacity and dimensionless separation factor are calculated.Keywords

This paper presents a variation of Fuzzy c-Means (FCM) algorithm that provides image clustering. The proposed algorithm incorporates the local spatial information and gray level information in a novel fuzzy way. The new algorithm is called C-Means with Fuzzy Local Information (CMFLI). CMFLI can overcome the disadvantages of known fuzzy c-means algorithm and at the same time enhances the clustering performance. The major characteristic of CMFLI is the use of fuzzy local information (both spatial and gray level) similarity measure, aiming to guarantee noise insensitiveness and image detail preservation. Furthermore, the proposed algorithm is fully free of empirically adjusted parameters (a, λg , λs etc.) incorporated into all other fuzzy c-means algorithms proposed in the literature. Experiments performed on synthetic and real world images show that CMFLI algorithm is efficient,providing robustness to noisy images.Keywords
