The present paper is a result of the authors' three years of botanical exploration of the Gora Range of Rajpipla forests. The forests are Mixed Dry Deciduous type with Tectona grandis as the major constituent. In all 460 plant species have been listed, of which 393 belong to dicotyledons, 64 to monocotyledons and 3 belong to pteridophytes.

Two hundred twenty nine isolates of Magnaporthe grisea were collected from finger millet cultivars at 14 locations in north India (Uttarakhand) and two locations in south India (Tamilnadu&Karnataka). Each isolate was tested for the mating types (Male fertile and female sterile) using standard fertile testers. Per cent isolates that neither mated nor produced perithecia was high among isolates collected from south India than those from Uttarakhand. Male fertile and hermaphrodite isolates from cooler region showed greater efficiency to produce perithecia. Results revealed that distribution of mating type varied with geographical region. Male fertile and female sterile isolates segregated in 1:1 ratio among field isolates collected from both north and south India. Field isolates from north India showed equal probability of getting male fertile, female sterile and hermaphrodite isolates, which suggested that probability for sexual reproduction in the population of M. grisea existed in nature in the central Himalayas of India.Keywords

The present investigation was carried out in different moist temperate forests of Garhwal Himalaya. The fruiting bodies of macrofungi were collected from these forests between July 2008 and September 2009. Frequent field visits and collections were made within the elevation range of 550-2500 msl in the districts Pauri, Tehri, Chamoli and Rudraprayag. As a result of an extensive field survey and microscopic study in laboratory, 40 taxa belonging to 11 families were identified. Two families and 2 taxa belonged to class- Ascomycetes viz: Family-Helvellaceae and Morchellaceae, and nine families and 38 taxa to class-Basidiomycetes viz: Family-Agaricaceae, Amanitaceae, Boletaceae, Cantharellaceae, Coprinaceae, Ganodermataceae Hydnagiaceae, Lycoperdaceae and Russulaceae. Some macrofungi are also being used as medicine viz: Morchella esculenta, Hydnum repandum, Agaricus campestris, Cantharellus cibarius, Coprinus comatus and Ganoderma lucidum.Keywords

The vegetation, and flora of Knedbrahma region of north Gujarat are discussed and the preliminary data based on two years survey are presented in this paper. 554 species have been enumerated which comprised 448 dicotyledons and 102 monocotyledons. Two new records for India namely, Desmodium neo-mexicanum A. Gray and Dalechampia scandens Linn. var. cordofana (Hochst.) Muell.-Arg. have been reported from this area under study. Five species such as Polycarpon tetraphyllum Linn., Melhania futteyporensis Munro ex Mast., Indigofera angulosa Edgew., Pulicaria crispa (Forsk.) Oliv. and Operculina petaloidea (Ghoisy) Van Oost., not mentioned in Cooke's flora of Presidency of Bombay (1901-1908) have been reported from the area.Full Text

Separation and purification are an integral part and a major cost factor in the chemical industry. Distillation is a very commonly used for solvent separation and purification process. It is neither cost effective nor process efficient when dealing with close-boiling and azeotropic solvent mixtures without modifying the relative volatility of the solvent components with an extraneous solvent or a non-volatile solute electrolyte or nonelectrolyte. The selection of a suitable modifier generally depends on the experimental determination of its effect on the Vapour–Liquid Equilibrium (VLE) of the solvent mixture. Acetic acid is most widely used as aliphatic carbonic acid. It is frequently used as a solvent like in manufacture of cellulose acetate or in manufacture of many pharmaceutical products. Aqueous acetic acid is obtained during these processes and recovery of which is of great significance. Separation of pure water from dilute solution of Acetic acid –water mixture in the concentration range of 1 % to 30 % Acetic acid by simple rectification is almost impossible as relative volatility of the mixture in this range approaches unity.We would then require towers with large number of stages which would be operated with high reflux ratio and required high energy costs and operating costs. In practice extraction with suitable solvent is carried out before pure recovery occurs during the rectification of azeotropic mixture. An alternative separation process is the addition of Lithium Bromide(LiBr) salt into acetic-acid water solution . Lithium bromide is largely soluble in water. Addition of salt will increase the boiling point of salt-water solution, there by separating comparatively pure acetic acid as overhead product. LiBr–water solution remains as residue from which LiBr can be readily separated by evaporation and reused. Experiments are carried out in laboratory with different concentrations of Acetic acid-water, in Othmer still which is vapor-liquid equilibrium apparatus. An Extractive distillation column will be designed based on experimental results. Cost analysis of this new separation technique will be carried out. The experimental data will be correlated to any model to calculate activity coefficients.Keywords
