Resources and Environment: Toxicity study of heavy metals pollutants in
waste water effluent samples collected from Taloja industrial estate of
Mumbai, India
The present research work deals with the assessment of pollution due to
toxic heavy metals in the industrial waste water effluents collected from
Taloja industrial belt of Mumbai. The study reveals that dyes, paints,
pharmaceutical and textile industries are some of the major industries
contributing to the heavy metal pollutants in the surrounding aquatic
environment. It was observed that paint manufacturing industries are the
major contributors of toxic Cr, Zn and Pb amounting to 35.2, 33.1, and 31.4
mg/L respectively. It was also observed that major contribution of Cu (33.3
mg/L) was from dyes manufacturing units, while maximum Fe concentration of
12.8 mg/L was found in effluent samples released from textile industries.
The concentration of Cd and Ni was found maximum in effluent samples
collected from pharmaceutical industries amounting to 35.8 and 33.6 mg/L
respectively. The overall results point out high concentration of toxic
heavy metals in the effluent samples collected from different industries.
These industrial effluents will pollute the near by water bodies affecting
the growth of vegetation and aquatic life. These toxic heavy metals when
released in aquatic environment will enter the food chain through bio-
magnification causing various health problems in humans. The results of the
present investigation point out the need to implement common objectives,
compatible policies and programmes for improvement in the industrial waste
water treatment methods.Keywords Industrial Effluent; Industrial Pollution;

Abtract New equation was applied for the Calculation of association
constant (KA) from the reaction of Cu(NO3)2 with Kryptofix-221 in mixed
(MeOH-DMF) and in absence and Presence of ligand at different temperatures.
From the experimental results, the molar conductance (?) were evaluated.
The limiting molar conductance (??) were also estimated. Gibbs free
energies of association (?GA) was also estimated, Moreover, recalculation
of (KA) was achieved by applying Shedlovsky and Fouss-Kraus extrapolation
methods. In addition, the molar solvated (V), Van der Waals (VW),
electrostriction (Ve) and apparent molar (ьv) volmes were calculated. Also,
the enthalpy change (?H) and the entropy change (T?S) for Cu(NO3)2 were
calculated. The degree of dissociation (?) were also calculated. All the
results were discussed in view of ion-solvent interactions. Click Here to

Frontiers in Science: Development of Automatic Alkaloid Removal System for
Dioscorea h ispida
Dioscorea hispida (D.hispida) is a poisonous plant which their tuber
contains toxic poison and can be consumed after the poison or dioscorine is
removed. The tubers were peeled, sliced and soaked in flowing water (river)
up to 7 days during traditionally detoxified process. Due to the
traditional processing methods for removal of dioscorine is difficult to
practice, we develop two types of equipment (wavy and spin) based on their
water circulation operations. This project consisted the stages of design,
fabricate and testing for the development of stand alone dioscorine removal
equipment. Survival of Cyprinus carpio fish in slicing tuber of D.hispida
extraction was used as a tool for detection of dioscorine removal. Results
indicate that water circulation of spin operation was more effective
compared to wavy type based on their capability of increasing pH activity
and survival of fish as in D.hispida tuber during 6 hours of detoxified
process. Therefore, this unique equipment can reduce the preparation time
and also handling process of detoxified D.hispida thus making it to be more
hygienic as compared to the traditional method in which river is used as a
medium for dioscorine removal. The manual operation for water inlet and
outlet for dioscorine removal system will replace for automatic operation
by using On / Off solenoid valve while the Peripheral Interface Controller
(PIC) is use for controlling input and output signal from sensor, solenoid
valve and motor pump. Conceptually, the system will enhance with automatic
timer which will pour out the dirty water and refill new water from inlet
automatically.D.hispida which entitle Ubi Gadong in Malaysia is a poisonous
plant where methodical studies have shown that its rhizome contains toxic
poison. It can only be consumed as a food after the poison of dioscorin is
removed. Approximately, over 600 Dioscorea species are consumed in various
parts of the world (Agbo and Treche, 1995). These edible starchy tubers are
important for cultural, economic and nutritional aspects in tropical and
subtropical region (Salam, 1990). D.hispida is a wild tuber species and
commonly found in secondary forest (Hahn, 1995). The common names of
D.hispida in Malaysia include Gadog, Gadong, Gadong lilin, Gadung mabuk,
Gadung, Ubi akas, Ubi arak, Taring pelanduk and Sulur gadung (Nashriyah et
al., 2010). These tubers are known to be consumed by people especially
during rainy season in lean period. The consumption of raw tuber can be
harmful since it contains of toxic alkaloids (Tattiyakul and Naksriarporn,
2010). Traditionally, it takes for up to 7 day of soaking D.hispida tubers
in flowing water for detoxified process before it safe for human
consumption (Udensi et al., 2008; Hudzari et al., 2011a). Click Here to

International Journal of Ecosystem: Study on Physico-Chemical Parameters of
Waste Water Effluents from Taloja Industrial Area of Mumbai, India
The present research work deals with the study of some of the important
physico-chemical parameters of industrial waste water effluents collected
from Taloja industrial belt of Mumbai. The study reveals that engineering,
paper mill, fine chemical, dyes, paint, pharmaceutical, petrochemical and
textile industries are some of the major industries responsible for
polluting the surrounding aquatic environment. It was observed that pH
values of effluent samples collected from paint, pharmaceutical and dyes
industries were slightly above and below the limit of 6.5 to 8.5 by ISI and
WHO. The effluent samples collected from textile industries shows extremely
high Total Dissolved Soild (TDS) content of 12023.6 mg/L and
correspondingly high Total Solid (TS) content of 13499.2 mg/L. The chloride
content in the effluents from textile industries was 238.4 mg/L which was
significantly high than acceptable limit of 200 mg/L set by WHO. The BOD
values of effluent samples collected from pharmaceutical, dyes, engineering
and paint industries were 1047.3, 776.2, 604.8 and 535.8 mg/L respectively
which lie above the maximum permitted BOD content of < 100 to 300 mg/L. The
COD values in the different industrial effluent samples were also very much
higher than maximum permissible limit of 4.0 mg/L according to USPH
Standard. The overall results highlight towards the discharge of highly
polluted waste water effluent from industries of Taloja Industrial area of
Mumbai. These industrial effluents have resulted in pollution of nearby
Kasardi River thereby affecting the growth of vegetation and aquatic life.
The results of the present investigation point out the need to implement
common objectives, compatible policies and programmes for improvement in
the industrial waste water treatment methods. Click Here to View Full

Electrical and Electronic Engineering: Optical Add Drop Multiplexer (OADM)
Based on Dense Wavelength Division Multiplexing Technology in Next
Generation Optical Networks
The OADM based on DWDM technology is moving the telecommunications industry
significantly closer to the development of optical networks. The OADM can
be placed between two end terminals along any route and be substituted for
an optical amplifier. Commercially available OADMs allow carriers to drop
and/or add up to multi channels between DWDM terminals. By deploying an
OADM instead of an optical amplifier, service providers can gain
flexibility to distribute revenue-generating traffic and reduce costs
associated with deploying end terminals at low traffic areas along a route.
The OADM is especially well-suited for meshed or branched network
configurations, as well as for ring architectures used to enhance
survivability. Moreover, An optical add/drop multiplexer with tunable
bandwidth offers several potential advantages, including optical
performance monitoring and dynamic bandwidth allocation. This paper has
proposed OADM for high transmission bit rates and products in next
generation optical communication networks based on dense wavelength
division multiplexing for different fiber link lengths at room temperature
for best performance efficiency. Click Here to View Full Article
Computer Science and Engineering: PID Type Stabilizer Design for Multi
Machine Power System Using IPSO Procedure
This paper presents a modified Iteration Particle Swarm Optimization (IPSO)
algorithm to tune optimal gains of a Proportional Integral Derivative (PID)
type multiple stabilizers and non-smooth nonlinear parameters (such as
saturation limits) for multi machine power system, simultaneously. The
problem of robustly tuning of PID based multiple stabilizer design is
formulated as an optimization problem according to the time domain-based
objective function which is solved by a modified strategy of PSO algorithm
called IPSO technique that has a strong ability to find the most optimistic
results. In the proposed algorithm, a new index named, Iteration Best, is
incorporated in standard Particle Swarm Optimization (PSO) to enrich the
searching behavior, solution quality and to avoid being trapped into local
optimum. To demonstrate the effectiveness and robustness of the proposed
stabilizers, the design process takes a wide range of operating conditions
and system configuration into account. The effectiveness of the proposed
stabilizer is demonstrated through nonlinear simulation studies and some
performance indices on a four- machine two areas power system in comparison
with the classical PSO and PSO with Time-Varying Acceleration Coefficients
(PSO-TVAC) based optimized PID type stabilizers. The results of these
studies show that the proposed IPSO based optimized PID type stabilizers
have an excellent capability in damping power system inter-area
oscillations and enhance greatly the dynamic stability of the power system
for a wide range of loading condition. Also, it is superior that of the PSO
and PSO-TVAC based tuned stabilizers in terms of accurateness, convergence
and computational effort. Click Here to View Full Article

International Journal of Astronomy: Is Planck's Constant - A Cosmological
Variable?
Within the expanding cosmic Hubble volume, Hubble length can be considered
as the gravitational or electromagnetic interaction range. Product of
'Hubble volume' and 'cosmic critical density' can be called as the 'Hubble
mass'. Based on this cosmic mass unit, authors noticed five peculiar semi
empirical relations in atomic, nuclear and cosmic physics. With these
applications it is possible to say that - during the cosmic evolution,
magnitude of Planck's constant increases with increasing cosmic time. This
may be the root cause of observed cosmic red shifts. By observing the
cosmological rate of change in Planck's constant, the future cosmic
acceleration can be verified from the ground based laboratory experiments.
With reference to the current concepts of distant and spatial variation of
the fine structure ratio, variation of the planck's constant can be
considered for further analysis. Click Here to View Full Article
