The present work investigates on the applicability of metal promoted sulphated zirconia
catalysts for the hydroxylation of phenol under mild conditions. The percentage conversion
and product distribution was highly sensitive towards the reaction parameters like the catalyst
composition, reaction temperature, H202/ phenol ratio and the solvent used.
The present study is an attempt to find out the ralation between RNA/DNA ratio, protein,percentage growth rate and specific growth rate of prawn,Penaeus indicus with respect to Nervous system, Eyestalk and Muscle tissues during ontogenesis. We have isolated and purified a natural agglutinin in the hemolymph of P.indicus with antigenecity, agglutinating, hemolytic and antibacterial properties. The influence of growth and environmental parameters on the level of agglutinin in the hemolymph was studied. Agglutinin concentration during normal growth process was compared. The agglutinin concentration in the hemolymph was quantified through developing ELISA, which is useful in health monitoring studies of individual species. Complete amino acid composition of both the subunits of P.indicus agglutinin were analysed. P.indicus agglutinin showed similarity to those proteins having antigenecity,hemolytic and agglutinating properties.Hence, agglutinin was considered as a natural defence protein in the hemolymph of P.indicus responsible for immune surveillance. The humoral defence mechanism of agglutinin was a co-operative effort with hemocytes and complement system. The composition of isolated agglutinin of P.indicus amino acids will be helpful in the synthesis of new antibacterial analogues which can be used against disease causing organisms.

Abstract:
Of 33 phages isolated from various shrimp farms in Kerala, India, six were
segregated to have broad spectrum lytic efficiency towards 87 isolates of Vibrio
harveyi with cross-infecting potential to a few other important aquaculture
pathogens. They were further tested on beneficial aquaculture micro-organisms
such as probiotics and nitrifying bacterial consortia and proved to be
noninfective. Morphological characterization by transmission electron
microscopy (TEM) and molecular characterization by RAPD and SDS-PAGE
proved them distinct and positioned under Caudovirales belonging to
Myoviridae and Siphoviridae

Abstract:
Giant freshwater prawn, Macrobrachium rosenbergii
(de Man), is an important commercial species with
considerable export value, ideal for cultivation
under low saline conditions and in freshwater zones
(Kurup 1994). However, despite more than a
decade of research on its larval production systems,
vibriosis still hampers seed production resulting in
high mortality rates. Among the different species of
vibrios, Vibrio alginolyticus has been isolated frequently
from diseased shrimp as the aetiological
agent of vibriosis and has been described as a
principal pathogen of both penaeids and nonpenaeids
(Lightner 1988; Baticados, Cruz-Lacierda,
de la Cruz, Duremdez-Fernandez, Gacutan, Lavilla-
Pitogo & Lio-Po 1990; Mohney, Lightner & Bell
1994; Lee, Yu, Chen, Yang & Liu 1996). Vibrio
fluvialis, V. alginolyticus, V. cholerae non-O1
(Fujioka & Greco 1984), Aeromonas liquifaciens
and V. anguillarum (Colorni 1985) have been
isolated from the larvae of M. rosenbergii. A
profound relationship between the abundance of
members of the family Vibrionaceae and larval
mortality (Singh 1990) and the predominance of
Vibrio in eggs, larvae and post-larvae of
M. rosenbergii (Hameed, Rahaman, Alagan &
Yoganandhan 2003) was reported. The present
paper reports the isolation, characterization, pathogenicity
and antibiotic sensitivity of V. alginolyticus
associated with M. rosenbergii larvae during an
occurrence of severe mass mortality at the ninth
larval stage.

Abstract:
Protease inhibitors are one of the most important tools of nature for
regulating the proteolytic activity of their target proteases. They are
synthesized in biological systems and they play a critical role in controlling
a number of diverse physiological functions. The current investigation
focused on the isolation, purification and characterization of a novel
protease inhibitor from Moringa oleifera. The results obtained during the
course of study opens new perspectives for the utilization of protease
inhibitor from Moringa oleifera for various pharmaceutical, agricultural and
food industries. The biological and physicochemical properties exhibited by
the novel protease inhibitor from Moringa oleifera clearly testify its
suitability for the development as a drug for application in pharmaceutical
industries such as anticoagulant agent or biocontrol agent in agriculture and
even as a food preservant. There is a scope for further research on the
structure elucidation and protein engineering towards a wide range of
further applications. Detailed structure/function analysis of these proteins is
important to facilitate their use in genetic engineering for various
applications.

Abstract:
The microorganisms are recognized as important sources of protease
inhibitors which are valuable in the fields of medicine, agriculture and
biotechnology. The protease inhibitors of microbial origin are found to be versatile
in their structure and mode of inhibition that vary from those of other sources.
Although surplus of low molecular weight non-protein protease inhibitors from
microorganisms have been reported, there is a dearth of reports on proteinaceous
protease inhibitors. The search for new metabolites from marine organisms has
resulted in the isolation of more or less 10,000 metabolites (Fuesetani and
Fuesetani, 2000) many of which are gifted with pharmacodynamic properties. The
existence of marine microorganisms was reported earlier, and they were found to
be metabolically and physiologically dissimilar from terrestrial microorganisms.
Marine microorganisms have potential as important new sources of enzyme
inhibitors and consequently a detailed study of new marine microbial inhibitors
will provide the basis for future research (Imada, 2004).

Abstract:
The present paper deals with the chemistry, isolation, separation, characterisation and stabilisation of the Marigold
oleoresin and its application as a natural food colorant. Marigold (Tagetes Erecta L), an ornamental plant belonging to
the composite family, has a rich source of natural antioxidant-Lutein. A natural pigment, xanthophylls offer an
alternative to synthetic dyes as a food colorant, due to its non-toxicity. Chromatographic separations of saponified and
unsaponified oleoresin were performed and Trans-Lutein identified as the major constituent. Well-preserved flowers
exhibit a high yield of Xanthophyll content (105.19 g/Kg) in contrast to the unpreserved flower sample (54.87 g/Kg),
emphasizing the significance of flower preservation in the extraction of xanthophyll. The stability and amount of
xanthophyll also increased from 105.19 g/Kg to 226.88 g/Kg on saponification and subsequent purification with

Abstract:
A new class of chiral polyurethanes containing
amido linkages in the polymer backbone have been synthesized
by reacting toluene diisocyanate with isosorbide
(IS) chiral moiety and the chromophores [N,N0-ethane-
1,2-diyl bis(6-hydroxy hexanamide), N,N0-butane-1,4-diyl
bis(6-hydroxy hexanamide) and N,N0-hexane-1,6-diyl bis
(6-hydroxy hexanamide)]. The corresponding chromophores
were obtained by the aminolysis of e-caprolactone by
using the diamines, diaminoethane, diaminobutane and
diaminohexane, respectively. All the polymers were synthesized
according to the symmetry conditions so as to
obtain the non-centrosymmetric environment. A series of
polyurethanes were synthesized by varying the chiral–
chromophore composition. The polyurethanes developed
were characterized by optical and thermal methods.

Abstract:
This paper describes JERIM-320, a new 320-bit hash function used for ensuring message integrity
and details a comparison with popular hash functions of similar design. JERIM-320 and FORK -256
operate on four parallel lines of message processing while RIPEMD-320 operates on two parallel
lines. Popular hash functions like MD5 and SHA-1 use serial successive iteration for designing
compression functions and hence are less secure. The parallel branches help JERIM-320 to achieve
higher level of security using multiple iterations and processing on the message blocks. The focus of
this work is to prove the ability of JERIM 320 in ensuring the integrity of messages to a higher
degree to suit the fast growing internet applications

In a leading service economy like India, services lie at
the very center of economic activity. Competitive organizations
now look not only at the skills and knowledge, but also at the
behavior required by an employee to be successful on the job.
Emotionally competent employees can effectively deal with
occupational stress and maintain psychological well-being. This
study explores the scope of the first two formants and jitter to
assess seven common emotional states present in the natural
speech in English. The k-means method was used to classify
emotional speech as neutral, happy, surprised, angry, disgusted
and sad. The accuracy of classification obtained using raw jitter
was more than 65 percent for happy and sad but less accurate for
the others. The overall classification accuracy was 72% in the
case of preprocessed jitter. The experimental study was done on
1664 English utterances of 6 females. This is a simple, interesting
and more proactive method for employees from varied
backgrounds to become aware of their own communication styles
as well as that of their colleagues' and customers and is therefore
socially beneficial. It is a cheap method also as it requires only a
computer. Since knowledge of sophisticated software or signal
processing is not necessary, it is easy to analyze
