Abstract:
This study aims to analyze, compare and contrast the behavioral competency of officials in commercial banks headquartered in Kerala. This is done by analyzing the soft skills/behavioral skills possessed by an individual employee in both clerical and managerial levels and the means adopted to enhance their said skills in near future. The study was conducted with the objective of analyzing the behavioral competency of the managers and clerical staff in the commercial banks headquartered in Kerala. The researcher has gone through the available literature with respect to employee competency, job satisfaction and employee performance evaluation to formulate the problem and conceptualize the framework of the study. The study concluded that the competency of the employees differs from one bank to the other but strengthening the employees’ competency is the only possible solution by which the banks can determine their future growth prospects. Only through competency, banks can achieve high level of performance especially under the globalised situation.

Abstract:
Concrete is a universal material in the construction industry. With natural
resources like sand and aggregate, fast depleting, it is time to look for alternate
materials to substitute these in the process of making concrete. There are instances
like exposure to solar radiation, fire, furnaces, and nuclear reactor vessels, special
applications like missile launching pads etc., where concrete is exposed to
temperature variations In this research work, an attempt has been made to understand the
behaviour of concrete when weathered laterite aggregate is used in both
conventional and self compacting normal strength concrete. The study has been
extended to understand the thermal behaviour of both types of laterised concretes
and to check suitability as a fire protection material. A systematic study of laterised concrete considering parameters like source of laterite aggregate, grades of Ordinary Portland Cement (OPC) and types of supplementary cementitious materials (fly ash and GGBFS) has been carried out to
arrive at a feasible combination of various ingredients in laterised concrete. A mix design methodology has been proposed for making normal strength laterised self compacting concrete based on trial mixes and the same has also been validated. The physical and mechanical properties of laterised concretes have been studied with respect to different variables like exposure temperature (200°C, 400°C and 600°C) and cooling environment (air cooled and water cooled). The behaviour of ferrocement elements with laterised self compacting concrete has also been studied by varying the cover to mesh reinforcement (10mm to 50mm at an interval of 10mm), exposure temperature and cooling environment.

To elucidate the effect of washing, on flesh components, mrigal flesh was washed through one, two and three washing cycles. Washing resulted in absorption of water (1-3%) and loss of fat (49%). 35% loss of soluble protein (SP) was noticed in the first washing itself and the loss is almost equally shared by the sarcoplasmic (18% of SP) and the myofibrillar proteins (17% of SP). The subsequent washings removed small portions of water-soluble sarcoplasmic proteins resulting in the concentration of myofibrillar proteins. 73% of the soluble protein was retained in the flesh after three washing cycles. The protein had undergone marginal conformational changes as reflected by the decrease in the actomyosin Ca super(2+) ATPase activity The rheological properties of the washed flesh were,however, significantly better than that of the unwashed mince

Abstract:
The distribution and accumulation of the rare earth elements (REE) in the sediments of the Cochin
Estuary and adjacent continental shelf were investigated. The rare earth elements like La, Ce, Pr, Nd,
Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and the heavy metals like Mg, V, Cr, Mn, Fe, Cu, Zn, U, Th
were analysed by using standard analytical methods. The Post-Archean Australian Shale composition
was used to normalise the rare earth elements. It was found that the sediments were more enriched with
the lighter rare earth elements than the heavier ones. The positive correlation between the concentrations
of REE, Fe and Mn could explain the precipitation of oxyhydroxides in the study area. The factor
analysis and correlation analysis suggest common sources of origin for the REEs. From the Ce-anomalies
calculated, it was found that an oxic environment predominates in all stations except the station No. 2.
The Eu-anomaly gave an idea that the origin of REEs may be from the feldspar. The parameters like
total organic carbon, U/Th ratio, authigenic U, Cu/Zn, V/Cr ratios revealed the oxic environment and
thus the depositional behaviour of REEs in the region

Abstract:
Myocardial ischemia is caused by the inadequate supply of blood to the myocardium usually as a result of coronary artery disease. Cardiovascular disease is the leading cause of death worldwide and coronary artery disease is the greatest contributor, with 7.5 million deaths annually. Currently available drugs are able to alleviate the symptoms but have undesirable effects and secondary complications. Tribulus terrestris L. root and fruit are used in Ayurveda to treat heart ailments. But a scientific validation of the protective property of the herb against myocardial ischemia and the mechanism by which Tribulus terrestris L. mediates the protection has not been carried out. The objective of the present thesis is to elucidate the molecular mechanism of the beneficial property of Tribulus terrestris L. fruit and root against myocardial ischemia and cardiac dysfunctions by employing in vitro and in vivo models.

Abstract:
The thesis on the"Benthic ecology of selected prawn culture fields and ponds near Cochin” was taken up with a view to provide information on the qualitative and quantitative distribution of benthos and their relationships to prawnproduction of different culture ecosystems and to the physico-chemical parameters influencing their production. A two-year observation was carried out in nine selected prawn culture systems including perennial ponds (stations 1 to 4) seasonal fields (stations 5 to 7) and contiguous canals (stations 8 and 9) during December 1988 to November 1989. All macro- and meiobenthic organisms contributing to the faua were identified and their abundance, distribution, diversity, biomass and trophic relationships between benthos and prawns were studied. The environmental variables studied were temperature pH, salinity, dissolved oxygen, alkalinity, nitrite-nitrogen, nitrate-nitrogen, amonianitrogen, phosphate and silicate of bottom water and organic carbon and texture of the soil
The thesis is presented in 4 Chapters. Chapter I presents an’ INTRODUCTION to the topic of study and a review of relevant works to bring an awareness to the present status of research in benthos and benthic ecology. Chapter 11, MATERIALS AND MTHODS, includes the techniques of sampling, preservation of samples and methods of analyses of various physico-chemical factors and area covered under the study is also given in this chapter. Chapter III, HYDROGRAPHY deals with the results of investigation and discussion onthe physico-chemical parameters of water and Chapter IV, SEDIMENT covers the sedimentoloical characteristics of the different culture systems followed by a detailed discussion. Chapter V, BOTTOM FAUNA presents an account on the various aspects of benthos and benthic ecology and the details of prawn production. A discussion on the overall assessment of interrelations between abiotic and biotic factors is given in Chapter VI, DISCUSSION. A critical evaluation of the implication of benthic production on prawn production under culture conditions and trophic relationships are also included in this chapter. An executive SUMMARY of the observations made during this study is presented in the final section of the thesis .
There are several centrality measures that have been introduced and studied for real world
networks. They account for the different vertex characteristics that permit them to be ranked
in order of importance in the network. Betweenness centrality is a measure of the influence
of a vertex over the flow of information between every pair of vertices under the assumption
that information primarily flows over the shortest path between them. In this paper we present
betweenness centrality of some important classes of graphs.
Biclustering is simultaneous clustering of both rows
and columns of a data matrix. A measure called Mean Squared
Residue (MSR) is used to simultaneously evaluate the coherence
of rows and columns within a submatrix. In this paper a novel
algorithm is developed for biclustering gene expression data
using the newly introduced concept of MSR difference threshold.
In the first step high quality bicluster seeds are generated using
K-Means clustering algorithm. Then more genes and conditions
(node) are added to the bicluster. Before adding a node the MSR
X of the bicluster is calculated. After adding the node again the
MSR Y is calculated. The added node is deleted if Y minus X is
greater than MSR difference threshold or if Y is greater than
MSR threshold which depends on the dataset. The MSR
difference threshold is different for gene list and condition list
and it depends on the dataset also. Proper values should be
identified through experimentation in order to obtain biclusters
of high quality. The results obtained on bench mark dataset
clearly indicate that this algorithm is better than many of the
existing biclustering algorithms

Abstract:
Chaotic synchronization of two directly modulated semiconductor lasers with
negative delayed optoelectronic feedback is investigated and this scheme is found to be
useful for e±cient bidirectional communication between the lasers. A symmetric bidirec-
tional coupling is identified as a suitable method for isochronal synchronization of such
lasers. The optimum values of coupling and feedback strength that can provide maxi-
mum quality of synchronization are identified. This method is successfully employed for
encoding/decoding both analog and digital messages. The importance of a symmetric
coupling is demonstrated by studying the variation of decoding efficiency with respect to
asymmetric coupling.

Abstract:
This study gave the first report on the biennial metal divergence in the sediments of Cochin
Estuarine system (CES). Surface sediments from 6 prominent regions of CES were sampled
in 2009 and 2011 for the geochemical and environmental assessment of trace metals (Cd,
Co, Cr, Cu, Pb Fe, Mg, Mn, Ni and Zn).Besides texture, total organic carbon (TOC) and
CHNS were also done. The contamination and risk assessment were performed by
determining geochemical indices. Comparison with sediment quality guidelines were done
to assess the probability for ecotoxicological threat to the estuary. Results showed that the
measured heavy metals had varied spatial distribution patterns, indicating that they had
complex origins and controlling factors

Abstract:
We have studied the bifurcation structure of the logistic map with a time dependant control parameter. By introducing a specific nonlinear variation for the parameter, we show that the bifurcation structure is modified qualitatively as well as quantitatively from the first bifurcation onwards. We have also computed the two Lyapunov exponents of the system and find that the modulated logistic map is less chaotic compared to the logistic map.
