Abstract:
Effect of chlorine doping on the opto-electronic properties of β-In2S3 thin film, deposited by spray pyrolysis
technique is studied for the first time. Chlorine was incorporated in the spray solution, using HCl. Pristine
sample prepared using In(NO3)3 and thiourea as the precursors showed very low photosensitivity. But upon
adding optimum quantity of chlorine, the photosensitivity increased by 3 orders. X-ray analysis revealed that
crystallinity was also increasing up to this optimum level of Cl concentration. It was also observed that
samples with high photosensitivity were having higher band gap. The present study proved that doping with
chlorine was beneficial as this could result in forming crystalline and photosensitive films of indium sulfide.

Abstract:
Commercial banks play a vital role in the economic development of a country like India. Indian economy in general and
banking services in particular have made rapid strides in the recent past. However, a sizeable section of the population,
particularly the vulnerable groups, such as weaker sections and low income groups, continue to remain excluded from
even the most basic opportunities and services provided by the financial sector. To address the issue of such financial exclusion
in a holistic manner, it is essential to ensure that a range of financial services is available to every individual

Abstract:
On line isotope separation techniques (ISOL) for production of ion beams of short-lived radionuclides
require fast separation of nuclear reaction products from irradiated target materials followed by a transfer into
an ion source. As a first step in this transport chain the release of nuclear reaction products from refractory
metals has been studied systematically and will be reviewed. High-energy protons (500 - 1000 MeV) produce
a large number of radionuclides in irradiated materials via the nuclear reactions spallation, fission and
fragmentation. Foils and powders of Re, W, Ta, Hf, Mo, Nb, Zr, Y, Ti and C were irradiated with protons
(600 - 1000 MeV) at the Dubna synchrocyclotron, the CERN synchrocyclotron and at the CERN PS-booster
to produce different nuclear reaction products.
The main topic of the paper is the determination of diffusion coefficients of the nuclear reaction products
in the target matrix, data evaluation and a systematic interpretation of the data. The influence of the ionic
radius of the diffusing species and the lattice type of the host material used as matrix or target on the
diffusion will be evaluated from these systematics. Special attention was directed to the release of group I, II
and III-elements. Arrhenius plots lead to activation energies of the diffusion process.
Lower partial moments plays an important role in the analysis of risks and
in income/poverty studies. In the present paper, we further investigate its importance
in stochastic modeling and prove some characterization theorems arising out of it. We
also identify its relationships with other important applied models such as weighted
and equilibrium models. Finally, some applications of lower partial moments in
poverty studies are also examined

Abstract:
The paper identifies twelve elements of ship recycling and highlights their respective roles and duties in a proposed ship
recycling system. The source and items of knowledgebase for ship recycling have been brought out. A new philosophy focusing clean
and safe ship recycling namely design for ship recycling has been introduced based on principles such as ecofriendliness, engineering
efficiency, energy conservation and ergonomics. The role of naval architects in ship recycling industry has been described based on the
above factors. The paper brings out the role of naval architects in ship recycling the way it has been practiced worldwide and proposed
by regulatory bodies. The authors have brought out the new concept of design for ship recycling and various aspects of it. The role of
naval architects in the practice of this new design philosophy which is ready to be embraced by the maritime industry has been
reiterated.

Abstract:
The objective of this study is to understand the reasons for the enhancement in
aerosol optical depth (AOD) over the Arabian Sea observed during June, July and
August. During these months, high values of AOD are found over the sea beyond
10◦ N and adjacent regions. The Arabian Sea is bounded by the lands of Asia
and Africa on its three sides. So the region is influenced by transported aerosols
from the surroundings as well as aerosols of local origin (marine aerosols). During
the summer monsoon season in India, strong surface winds with velocities around
15 m s−1 are experienced over most parts of the Arabian Sea. These winds are capable
of increasing sea spray activity, thereby enhancing the production of marine
aerosols. The strong winds increase the contribution of marine aerosols over the
region to about 60% of the total aerosol content. The main components of marine
aerosols include sea salt and sulphate particles. The remaining part of the aerosol
particles comes from the western and northern land masses around the sea, of
which the main component is transported dust particles. This transport is observed
at higher altitudes starting from 600 m. At low levels, the transport occurs mainly
from the Indian Ocean and the Arabian Sea itself, indicating the predominance
of marine aerosols at these levels. The major portion of the total aerosol loading
was contributed by coarse-mode particles during the period of study. But in the
winter season, the concentration of coarse-mode aerosols is found to be less. From
the analysis, it is concluded that the increase in marine aerosols and dust particles
transported from nearby deserts results in an increase in aerosol content over the
Arabian Sea during June, July and August.

Abstract:
“At resale stores I have seen brand new clothes with original price tag
still hanging from the sleeve. Some children have so many toys that they stay
frustrated, not knowing which one to pick up for their next amusement.
Presumably sensible adults trade in perfectly good cars just to have something
shinier and newer. Didn’t us once live productive normal lives, without all
these gadgets” [Cunningham (2005)]. During late eighties, nearly forty four
percent of the participants, who took part in a consumer survey conducted in
the US, responded positively to the question “My closets are filled with still
2
unopened items” [Faber and O’Guinn (1988)]. Reading such excerpts does not
greatly surprise us anymore; as such reports have become common now. For
many people shopping has moved beyond something that caters to their needs
and wants and has become a hobby [Cunningham (2005)], an activity that they
engage in to satisfy their hedonistic or pleasure-seeking goals [Ramnathan and
Menon(2006), O’Cass and McEween (2004), Faber and O’Guinn (1989)].
Others look at their new possession as something that fills a void in their lives
[Belk (1985), Diener et al. (1993)].

Abstract:
The main objective of the study is primarily to determine the magnitude of selected trace elements, the concentrations of which would possibly accelerate growth resulting in larger biomass and sustained period of exponential phase for economically viable harvest. The study on the effect of three trace elements namely Cu, Mn and Zn on two species of algae,ISOChrySiS galbana Parke and Synechocystib salina Wislouch under different conditions of salinity, PH and temperature involves several combinations for each metal, from which the relative set of conditions has been adduced. The scheme of the experiments was statistically designed for interpretation of data and factors were assessed and graded according to relative importance. The methodology adopted for data interpretation is analysis of variance by split-plot design method.
The thesis has been divided into five chapters. The introductory chapter explains the relevance of the research work undertaken. Chapter 11 gives a review on the work pertaining to the above mentioned three trace elements in relation to nutrition as well as on the toxic aspects about which there is an abundance of literature. Chapter Ill presents a detailed description of the material and specialised methods followed for the study. The results and conclusions of the various experiments on effect of metals on growth and other physiological activities are discussed in Chapters IV and V.

Abstract:
In wireless sensor networks, the routing
algorithms currently available assume that the sensor nodes are
stationary. Therefore when mobility modulation is applied to the
wireless sensor networks, most of the current routing algorithms
suffer from performance degradation. The path breaks in mobile
wireless networks are due to the movement of mobile nodes, node
failure, channel fading and shadowing. It is desirable to deal with
dynamic topology changes with optimal effort in terms of
resource and channel utilization. As the nodes in wireless sensor
medium make use of wireless broadcast to communicate, it is
possible to make use of neighboring node information to recover
from path failure. Cooperation among the neighboring nodes
plays an important role in the context of routing among the
mobile nodes. This paper proposes an enhancement to an existing
protocol for accommodating node mobility through neighboring
node information while keeping the utilization of resources to a
minimum.
