These noctuid species have been found to be feeding on 56 spp. of agricultural crops, economically important plants and water weed. Of the total caterpillar species, under 6 sub-families, 14 spp. of various sub-families, excepting Cuculiinae, are associated with different agricultural crops. This accounts for 63.63% of noctuid-fauna studied. The highest number of caterpillar species i.e. 13 (Cuculines, Heliothines, Noctuines and Plusiines), feed on 28 spp. of medicinal / aromatic plants. This is followed by8 spp. of noctuids, devouring vegetable crops (9 spp.). 6 spp. of caterpillars are associated with 4 spp. of cereal / food crops, 4 spp. with legumes (5spp.), 3 spp. feeding fodder crops (3 spp.), 2 spp. each associated with fruit crop/tree (2 spp.), ornamental plants (2 spp.) and rape seed, and 1 sp. each of caterpillar feeding on mulberry and common water hyacinth, belonging to different subfamilies of noctuid moths. An up-to-date systematic Checklist of noctuids, associated with crops and plant species, has been provided. Besides, species diversity of noctuid-fauna on host crops/ plants, has been included.

An endemic species Indian White banded Shrimp, Caridina cf. babaulti was selected, as the documented information about the species is scare. Thus, this study was conducted to gather some information on its breeding behavior and life cycle until first maturity in laboratory condition.10 pairs of Indian White banded Shrimp, Caridina cf. babaulti are kept in confined system separately. The tanks are populated with common aquatic plants (Java fern Microsorum pteropus, Amazon sword Echinodorus bleherae, Anubias nana, Cryptocoryne sp., Rotala indica and mosses (java moss Taxiphyllum barbieri, Christmas moss Vesicularia montagnei) and regulated with periodic photoperiods and Co2 supply. With carefully monitored water quality parameters, the selected species was bred in confined system. It was observed that water temperature is one of the parameter that played a crucial role in influencing the spawning behavior of the species. Larvae assume a benthic lifestyle after hatching, i.e. they are miniature versions of the adults. There is no planktonic larval stage. The hatchlings of this shrimp are extremely small and grow slowly.

The mechanical properties of these composites were investigated and it was found that their tensile strength was somewhat lower than that predicted by the rule-of-mixtures; failure occurred predominantly by fibre pull-out. Details of the optical microscopic studies and the microhardness data are presented. This reveals that the fibre-to-matrix bonding is relatively weak as a result of the more-than-desirable interfacial reaction. Several inter-metallic compounds have been identified at the interface. Growth kinetics of these interface intermetallic compounds arediscussed.

Phosphotungstic acid was used to anchor the Wilkinson catalyst to an alumina support by an interaction between the heteropoly acid and the rhodium atom of the complex. The hydrogenation of b pinene over the anchored catalyst was accompanied by some isomerization to a-pinene which was subsequently hydrogenated along with the b pinene to the pinanes with selectivities to the cis (endo) pinane in the 85-88 % range at near 100 % conversion. With the homogeneous Wilkinson catalyst an 88 % selectivity to cis pinane was also observed but only at 82 % conversion. The use of a 1 % Rh/Al 2 O 3 catalyst for this hydrogenation gave some unexpected results. There was a facile isomerization to a pinene which was not hydrogenated further. The reaction stopped at about 30 % conversion at which time the cis and trans pinanes were present in near equal amounts in about 16-18 % yields.

BACKGROUND OF THE INVENTION 0003 Lactic acid, 2-hydroxy-propionic acid (also known as C.-hydroxy-propionic acid), is one of the commodity chemicals produced from biomass through fermentation at low cost. Lactic acid possesses a hydroxyl group and a car boxyl group. The presence of two different functional groups makes lactic acid an attractive feedstock for the production of number of commodity organic chemicals such as poly L-lac tic acid, acrylic acid, 2,3-pentanedione, pyruvic acid, propi onic acid, 1,2-propanediol, acetaldehyde, dilactide and alkyl lactate which are traditionally derived from petrochemical feedstock. The increase in the oil price accompanied by an increase in the efficiency of production of lactic acid through biological fermentation using renewable resources has made the conversion of lactic acid to various commodity chemicals more attractive. It has become an economically viable option for commercial production of acrylic acid using lactic acid derived from biological resources. 0004 Acrylic acid, an O.B unsaturated acid is one of the commodity chemicals that can be derived from lactic acid through a single-step catalytic dehydration. During 2010 about 4,400,000 metric tons of acrylic acid and about 3,900, 000 metric tons of acrylate ester were produced from petro chemical feedstock by two-step gas-phase oxidation of pro pylene. Acrylic acid is used in the manufacture of polymeric flocculants, Super absorbents, dispersants, coatings, paints, adhesives, paper products, construction chemicals, water treatment chemicals, and binders for leather, paper and tex tile.

The reaction uses an 80% aqueous glycerol solution and a hydrogen pressure of psi. The primary by-product is ethylene glycol formed in 1-3% yield. In a reaction run continuously for 24 d using a sample of a commercial preparation of Raney Cu, the selectivity to propylene glycol at 100% glycerol conversion was 94.6% with a Space Time Yield (STY) of 0.49 g of 1,2-propylene glycol/cc Raney Cu/h. Ethylene glycol was formed in 2.5% yield while methanol, ethanol, n-propanol 1,3-propylene glycol and acetol were present in less than 1% yield.
