Solutions of System of Fractional Partial Differential Equations

In this paper, system of fractional partial differential equation which has numerous applications in many fields of science is considered. Adomian decomposition method, a novel method is used to solve these type of equations. The solutions are derived in convergent series form which shows the effectiveness of the method for solving wide variety of fractional differential equations

Technology of processing mussel meat

Green mussel (Perna viridis) and brown mussel (P.indica) are available in substantial quantities from their natural beds along the south- east and south-west coasts of India respectively. Mussel is locally collected for its meat which is consumed in the nearby areas. Mussel meat normally finds favour with people of low income group and that too when the fish is scarce or costly, which often results in poor economic returns to the collector

Phytoplankton

Investigations on phytoplankton of the Indian Seas has assumed great significance during the last 5 decades. As these microscopic organisms fluctuated in response to climatic changes, water movements, seasonal variations, nutrient content of the water etc. they form an important and convenient link in the assessment of the stock of potential resources. The shelf and oceanic waters of the Indian seas show fluctuations in the standing crop of phytoplankton due to the effect of two monsoons. Available data indicated that the waters along the west coast of India are more fertile than that along the east coast mainly due to upwelling and other favourable factors conducive to phytoplankton growth. Some of the ecological factors contributing to the pattern of production of phytoplankton are also briefly discussed

Primary production

Studies on primary pruuuciion oj ine Indian Seas in general and adjacent ecosystems such as estuaries, mangroves, mud banks and coastal environments in particular are briefly discussed, in the light oJ the data collected over the years by various Expeditions and also by the investigations conducted in localised regions. The results indicated that the general trend of primary production vary both in space and time and also a seaward decrease in the production. The factors affecting and favouring the primary production of the Indian Seas is also presented. The annual production rates of west coast and east coast andpotential estimates of resources derivedfrom primary production is also discussed. The annual carbon production for the EEZ of India has been com^puted as 283 million tonnes and potential harvestable resources available in this region derived as 5.5 million tonnes, based on primary production. Future investigations on productivity through chlorophyll analysis arc also projected

Preliminary studies on nannoplankton productivity

The contribution of the nannoplankton to the total productivity was studied for nine months in coastal waters of Cochin. On an average, - nannoplankton accounted for 66.40% of the observed productivity. The mean assimiIation ratios between the total algal and nannoplankton fraction were very low (1.29 and 0.94 respectively)

Proceedings of the Second workshop on scientific results of FORV Sagar Sampada

Since inception in 1984, the Fisheries and Oceanographic Research Vessel Sagar Sampada, with sophisticated modern facilities onboard, has undertaken more than 140 cruises all over the Indian Ocean primarily in our Exclusive Economic Zone for fishery and oceanographic survey. Scientists from many institutions have made use of this facility to explore the resource potential in our sea and to understand its correlation with the environmental parameters. These survey and exploration efforts are continuing. This volume contains many papers which are the outcome of research work carried out onboard 'Sagar Sampada' during last five years (1989-1993) and presented in a Workshop to evaluate the scientific work. About 60 papers, included in this volume, bring out the results pertaining to environmental assessment, hydrology, productivity estimates, fishery resources availability, fishing technology, pollution monitoring etc. These relate mainly to the Arabian Sea, Bay of Bengal and Lakshadweep, Andaman and Nicobar Islands groups in the EEZ of India. These efforts along with other mission-oriented cruises have yielded valuable information on the fishery resources and their distribution in space and time

Color Skyrmions in the Quark-Gluon Plasma

We consider the general formulation of nonabelian fluid dynamics based on symmetry considerations. We point out that, quite generally, this admits solitonic excitations which are the color analog of skyrmions. Some general properties of the solitons are discussed.Comment: LaTeX, 13 pages, references adde

Structural study, NCA, FTIR, FT-Raman spectral investigations, NBO analysis and thermodynamic functions of N-benzyloxy carbonyl-L-alanine

The FTIR and FT-Raman spectra of N-benzyloxy carbonyl-L-alanine have been recorded and analyzed. Natural bond orbital analysis has been carried out for various intra-molecular interactions that are responsible for the stabilization of the molecule. HOMO-LUMO energy gap has been computed with the help of density functional theory. The statistical thermodynamic functions (heat capacity, entropy, vibrational partition function and Gibbs energy) have been obtained for the range of temperature 100-1000 K. The infrared and Raman spectra have been also predicted from the calculated intensities. Comparison of the experimental and theoretical spectra values provides important information about the ability of the computational method to describe the vibrational modes. In addition to these, Mulliken’s atomic charges associated with each atom have also been reported and mapped molecular electrostatic potential (MEP) surfaces have also been performed with the same level of DFT

Reverse Phase Liquid Chromatography Coupled with Quadra pole- Time of Flight Mass Spectrometry for the Charecterisation of Phenolics from Acacia Catechu (L.f.) Willd.

A rapid method was developed for the identification of phenolics from Acacia Catechu .The analysis ofphenolic compounds was carried out by reversed-phase high-performance liquid chromatography (RPHPLC)coupled to electrospray ionization-time-of-flight mass spectrometry (ESI-Q-TOF-MS). Theaccurate mass data for the molecular ions were processed using the software Mass Hunter workstation (Agilent Technologies), which provided a list of possible elemental formulas by using theMolecular featured extraction editor. The subsequent structure characterization was carried out by atandem mass spectrometric method. Fragmentation behavior of phenolic compounds was investigatedusing ion trap mass spectrometry in negative mode. The total fragmentation of the compound ionleading to other fragments was corroborated by MS–MS. Five phenolic compounds have beenidentified from the methanolic extract of Acacia Catechu

Vibrational (FT-IR and FT-Raman) spectra and quantum chemical studies on the molecular structure of p-hydroxy-N-(p-methoxy benzylidene) aniline

The FT-IR and FT-Raman spectra of p-hydroxy-N-(p-methoxy benzylidene) aniline have been recorded in the region 4000-400 cm−1 and 3500-100 cm−1, respectively. The optimized molecular geometry, vibrational frequencies in ground state have been calculated using density functional B3LYP methods (DFT) with 6-31+G(d,p) and 6-311++G(d,p) basis sets. The observed FT-IR and FT-Raman vibrational frequencies have been analysed and compared with theoretically predicted vibrational frequencies. The geometries and normal modes of vibration obtained from B3LYP/6-311+G(d,p) and B3LYP/6-311++G(d,p) methods are reliable compared with the experimental data. The natural bonding orbital (NBO) analysis of the investigated molecule have been computed using DFT/ B3LYP/6-311++G(d,p) calculations. The calculated HOMO and LUMO energies show that charge transfer occurs within molecule
