Abstract:
Assessment water’ quality nowa-days in global scenario implies the need for a
reference point against which monitoring can be measured and weighed. Aquatic
ecosystenis as part of the natural environment are balanced both witliin tlicinselves and
with other environmental compartments and this equilibrium is subject to natural
variations and evolutions as well as variations caused by human intervention. The
present assessnient is to identify. and possibly quantify, anthropogenic influences over
time against a “natural baseline situation. Water pollution problems have only recently
been taken seriously in retrospect. Once damage occurred, it becomes immeasurable,
and control action cannot be initiated

Abstract:
The present investigation on the Muvattupuzha river basin is an integrated approach based on hydrogeological, geophysical, hydrogeochemical parameters and the results are interpreted using satellite data. GIS also been used to combine the various spatial and non-spatial data. The salient finding of the present study are accounted below to provide a holistic picture on the groundwaters of the Muvattupuzha river basin. In the Muvattupuzha river basin the groundwaters are drawn from the weathered and fractured zones. The groundwater level fluctuations of the basin from 1992 to 2001 reveal that the water level varies between a minimum of 0.003 m and a maximum of 3.45 m. The groundwater fluctuation is affected by rainfall. Various aquifer parameters like transmissivity, storage coefficient, optimum yield, time for full recovery and specific capacity indices are analyzed. The depth to the bedrock of the basin varies widely from 1.5 to 17 mbgl. A ground water prospective map of phreatic aquifer has been prepared based on thickness of the weathered zone and low resistivity values
(<500 ohm-m) and accordingly the basin is classified in three phreatic potential zones as good, moderate and poor. The groundwater of the Muvattupuzha river basin, the pH value ranges from 5.5 to 8.1, in acidic nature. Hydrochemical facies diagram reveals that most of the samples in both the seasons fall in mixing and dissolution facies and a few in static and dynamic natures. Further study is needed on impact of dykes on the occurrence and movement of groundwater, impact of seapages from irrigation canals on the groundwater quality and resources of this basin, and influence of inter-basin transfer of surface water on groundwater.

Abstract:
Water constitutes the basic resource for life. Management of coastal
aquifers, which are the important sources of freshwater that feed the rapid
economic growth of the region is facing increasing challenges. A large portion of
the global population inhabits the coastal and adjoining areas leading to a high
demand for water both surface and ground water resources of coastal tracts.
With increasing population this puts significant stress on water resources of
many of the coastal tracts of the world. Several recent studies have indicated that
coastal aquifers of Cenozoic age are globally under threat due to several
reasons.
Climate change is expected to affect the freshwater resources of coastal
aquifers, which in turn will affect half of the global population residing in coastal
areas. Sea-level rise will induce landward migration of the freshwater-saltwater
transition zone, i.e., seawater or saltwater intrusion, jeopardizing freshwater
availability. In order to facilitate the management of fresh coastal groundwater
resources, a comprehensive understanding of the SLR-SWI relationship is
crucial.

Abstract:
The primary habitat of Salmonella is the gastrointestinal tract of
animals and they are discharged into the water bodies through the feces.
Aquatic animals act as asymptomatic reservoirs of a wide range of Salmonella
serotypes. The inevitable delay in the detection of Salmonella contamination
and the low sensitivity of the conventional methods is a serious issue in the
seafood industry. Due to the indiscriminate use, the antibiotics are finally
accumulated in the aquatic environment which provides the required antibiotic
stress for the emergence of more and more antibiotic resistant phenotypes ofSalmonella. Several genetic determinants like integrons, genomic islands etc.
play their role in acquisition and reshuffling of antibiotic resistance genes. A
large number of virulence determinants are required for Salmonella
pathogenicity. The virulence potential of Salmonella is determined, to some
extent, by the presence of phages or phage mediated genes in the bacterial
genome. There is much intra-serotype polymorphism in Salmonella and
epidemiological studies rely on genetic resemblance of the isolated strains.
Proper identification of the strain employing the traditional and molecular
techniques is a prerequisite for accurate epidemiological studies (Soto et al.,
2000).
In this context, a study was undertaken to determine the prevalence of
different Salmonella serotypes in seafood and to characterize them

Abstract:
This paper presents the results of a field experiment conducted in Kerala,
South India, to test the effectiveness of coir geotextiles for embankment protection.
The results reveal that treatment with geotextile in combination with grass is an effective
eco-hydrological measure to protect steep slopes from erosion. In the context
of sustainable watershed management, coir is a cheap and locally available material
that can be used to strengthen traditional earthen bunds or protect the banks of village
ponds from erosion. Particularly in developing countries, where coir is abundantly
available and textiles can be produced by small-scale industry, this is an attractive alternative
for conventional methods. The paper analyses the performance of different
treatments with regard to soil moisture content, protection against erosion and biomass
production

Abstract:
Increase in sea surface temperature with global
warming has an impact on coastal upwelling. Past two decades
(1988 to 2007) of satellite observed sea surface temperatures
and space borne scatterometer measured winds have provided
an insight into the dynamics of coastal upwelling in the
southeastern Arabian Sea, in the global warming scenario.
These high resolution data products have shown inconsistent
variability with a rapid rise in sea surface temperature between
1992 and 1998 and again from 2004 to 2007. The upwelling
indices derived from both sea surface temperature and wind have
shown that there is an increase in the intensity of upwelling
during the period 1998 to 2004 than the previous decade. These
indices have been modulated by the extreme climatic events
like El–Nino and Indian Ocean Dipole that happened during
1991–92 and 1997–98. A considerable drop in the intensity of
upwelling was observed concurrent with these events. Apart
from the impact of global warming on the upwelling, the
present study also provides an insight into spatial variability of
upwelling along the coast. Noticeable fact is that the intensity of
offshore Ekman transport off 8oN during the winter monsoon is
as high as that during the usual upwelling season in summer
monsoon. A drop in the meridional wind speed during the years
2005, 2006 and 2007 has resulted in extreme decrease in
upwelling though the zonal wind and the total wind magnitude
are a notch higher than the previous years. This decrease in
upwelling strength has resulted in reduced productivity too.

Abstract:
Inter-digital capacitive electrodes working as electric field sensors have been developed for
touch panel applications. Evaluation circuits to convert variations in electric fields in such sensors into
computer compatible data are commercially available. We report development of an Interdigital
capacitive electrode working as a sensitive pressure sensor in the range 0-120 kPa. Essentially it is a
touch/proximity sensor converted into a pressure sensor with a suitable elastomer buffer medium
acting as the pressure transmitter. The performance of the sensor has been evaluated and reported.
Such sensors can be made very economical in comparison to existing pressure sensors. Moreover, they
are very convenient to be fabricated into sensor arrays involving a number of sensors for distributed
pressure sensing applications such as in biomedical systems.
