Abstract:
. The cotton mill industry is one of the important medium and
large-scale industries in the State of Kerala. Due to the widespread
development of the handloom industry in the State, there is an environment
conducive to the growth of cotton spinning mills which produce
yarn, the raw material required by the handloom industry. New spin—
ing mills are being commissioned. But the performance of the existing
cotton spinning and weaving mills in the State is not quite satisfactory.
Hence an analysis has been carried out into the profitability
and financial position of the industry in Kerala. The objective
of the study is to make a financial analysis of the industry covering
various aspects such as cost structure, productivity, asset structure,
financial structure and working capital management.

Abstract:
The method of preparation of ZnS phosphors doped with praseodymium and copper is given. The electroluminescence (EL) spectrum of ZnS:Pr,Cl has two broad bands at 470 and 570 nm. ZnS:Cu,Pr,Cl gives white emission with spectral peaks at 470, 520, 570 and 640 nm. The EL spectra of both types of phosphor exhibit a conspicuous colour shift as the frequency of the excitation voltage is varied. Detailed investigations show that the relative intensities of spectral peaks are strongly dependent on the frequency of the excitation voltage. The colour shift is explained on the basis of the Schon-Klasens model.

Abstract:
The thesis entitled Study on Accelerators in Rubber Vulcanization with Special Reference to the Binary Systems Containing Substituted Dithiobiurets. It includes a detailed study on the binary accelerator systems containing substituted dithiobiurets in natural rubber and NR latex and dithiobiurets in SBR and NR-SBR blends vulcanization systems. It deals with the experimental procedure adopted for the preparation of DTB-II and DTB-III; the procedure for compounding and vulcanization and determination of physical properties like modulus, tensile strength, elongation at break, hardness, compression set, heat build up etc. The results indicate that there is efficient acceleration activity of the dithiobiurets in the vulcanization of natural rubber latex containing TMT. The study of dithiobiurets in natural rubber and NR latex reveal that they are having definite accelerating effect in SBR vulcanization systems.

Abstract:
The present study brings out the influence of transport dynamics on the
aerosol distribution over the Indian region at a few selected geographically distinct
locations. Over the Bay of Bengal the dominant pathway of aerosol transport during the
pre-monsoon period is through higher altitudes (~ 3 km); directed from the Indian main
land. In contrast, the aerosol pathways over the Arabian Sea during the same period are
quite complex. They are directed from geographically different environments around the
ocean through different altitudes. However in general, the day-to-day variability of AOD at
both these regions is significantly influenced by the features of atmospheric circulation
especially, the wind convergence at higher altitudes (around 3 km). Over the Ganga Basin
during the winter period, the wind convergence at lower altitudes (< I km) govems the
shon term variations in AOD, while the mean AOD distribution at this location is mainly
governed by the local anthropogenic sources.

Abstract:
Futures trading in Commodities has three specific economic functions
viz. price discovery, hedging and reduction in volatility. Natural rubber
possesses all the specifications required for futures trading. Commodity
futures trading in India attained momentum after the starting of national level
commodity exchanges in 2003. The success of futures trading depends upon
effective price risk management, price discovery and reduced volatility which
in turn depends upon the volume of trading. In the case of rubber futures
market, the volume of trading depends upon the extent of participation by
market players like growers, dealers, manufacturers, rubber marketing
co-operative societies and Rubber Producer’s Societies (RPS). The extent of
participation by market players has a direct bearing on their awareness level
and their perception about futures trading.
In the light of the above facts and the review of literature available on
rubber futures market, it is felt that a study on rubber futures market is
necessary to fill the research gap, with specific focus on (1) the awareness and
perception of rubber futures market participants viz. (i) rubber growers,
(ii) dealers, (iii) rubber product manufacturers, (iv) rubber marketing
co-operative societies and Rubber Producer’s Societies (RPS) about futures
trading and (2) whether the rubber futures market is fulfilling the economic
functions of futures market viz. hedging, reduction in volatility and price
discovery or not.
The study is confined to growers, dealers, rubber goods manufacturers,
rubber marketing co-operative societies and RPS in Kerala. In order to achieve
the stated objectives, the study utilized secondary data for the period from
2003 to 2013 from different published sources like bulletins, newsletters,
circulars from NMCE, Reserve Bank of India (RBI), Warehousing Corporation and traders. The primary data required for this study were collected from rubber
growers, rubber dealers, RPS & Rubber Marketing Co-operative Societies and
rubber goods manufacturers in Kerala. Data pertaining to the awareness and
perception of futures trading, participation in the futures trading, use of spot
and futures prices and source of price information by dealers, farmers,
manufacturers and cooperative societies also were collected. Statistical tools
used for analysis include percentage, standard deviation, Chi-square test,
Mann – Whitney U test, Kruskal Wallis test, Augmented Dickey – Fuller test
statistic, t- statistic, Granger causality test, F- statistic, Johansen co – integration
test, Trace statistic and Max –Eigen statistic.
The study found that 71.5 per cent of the total hedges are effective and
28.5 per cent are ineffective for the period under study. It implies that futures
market in rubber reduced the impact of price risks by approximately
71.5 per cent. Further, it is observed that, on 54.4 per cent occasions, the
futures market exercised a stabilizing effect on the spot market, and on
45.6 per cent occasions futures trading exercised a destabilizing effect on the
spot market. It implies that elasticity of expectation of futures market in rubber
has a predominant stabilizing effect on spot prices. The market, as a whole,
exhibits a bias in favour of long hedges. Spot price volatility of rubber during
futures suspension period is more than that of the pre suspension period and
post suspension period. There is a bi-directional association-ship or
bi-directional causality or pair- wise causality between spot price and futures
price of rubber. From the results of the hedging efficiency, spot price
volatility, and price discovery, it can be concluded that rubber futures market
fulfils all the economic functions expected from a commodity futures market.
Thus in India, the future of rubber futures is Bright…!!!

Abstract:
In this study we combine the notions of fuzzy order
and fuzzy topology of Chang and define fuzzy ordered
fuzzy topological space. Its various properties are
analysed. Product, quotient, union and intersection
of fuzzy orders are introduced. Besides, fuzzy order
preserving maps and various fuzzy completeness are
investigated. Finally an attempt is made to study the
notion of generalized fuzzy ordered fuzzy topological
space by considering fuzzy order defined on a fuzzy subset.

Abstract:
Mathematical models are often used to describe
physical realities. However, the physical realities are
imprecise while the mathematical concepts are required to be
precise and perfect. The 1st chapter give a brief summary of the
arithmetic of fuzzy real numbers and the fuzzy normed
algebra M(I). Also we explain a few preliminary definitions
and results required in the later chapters. Fuzzy real
numbers are introduced by Hutton,B [HU] and Rodabaugh,
S.E[ROD]. Our definition slightly differs from this with an
additional minor restriction. The definition of Clementina
Felbin [CL1] is entirely different. The notations of
[HU]and [M;Y] are retained inspite of the slight difference
in the concept.the 3rd chapter In this chapter using the completion M'(I) of M(I)
we give a fuzzy extension of real Hahn-Banch theorem. Some
consequences of this extension are obtained. The idea of
real fuzzy linear functional on fuzzy normed linear space is
introduced. Some of its properties are studied. In the
complex case we get only a slightly weaker analogue for the
Hahn-Banch theorem, than the one [B;N] in the crisp case

Abstract:
Mathematical models are often used to describe
physical realities. However, the physical realities are
imprecise while the mathematical concepts are required to be
precise and perfect. Even mathematicians like H. Poincare
worried about this. He observed that mathematical models
are over idealizations, for instance, he said that only in
Mathematics, equality is a transitive relation. A first
attempt to save this situation was perhaps given by K.
Menger in 1951 by introducing the concept of statistical
metric space in which the distance between points is a
probability distribution on the set of nonnegative real
numbers rather than a mere nonnegative real number. Other
attempts were made by M.J. Frank, U. Hbhle, B. Schweizer, A.
Sklar and others. An aspect in common to all these
approaches is that they model impreciseness in a
probabilistic manner. They are not able to deal with
situations in which impreciseness is not apparently of a
probabilistic nature. This thesis is confined to introducing and developing a theory of fuzzy semi inner product spaces.

Abstract:
The healthcare sector in Kerala is witnessing a spiralling growth due to the
healthy economic development and the serious outlook of individuals towards
personal health. Private sector is thriving exuberantly well since there is a wide gap
between demand and supply for healthcare due to the lack of government initiatives.
The proliferation of these private hospitals have paved the way for many unhealthy
practices like poor working conditions, low wages, excess workload and lack of
retirement and welfare measures to the employees. This state of affairs demanded a
serious investigation into the functioning of the private hospitals in Kerala, especially
on the human resource management practices, as the success of every organisation
depends on the satisfaction level of its employees, which, in turn, will benefit the
consumer, i.e., the patients.
Hence the present study was undertaken to find out the extent of human
resource management practices in private hospitals in Kerala with a view to suggest
appropriate remedial measures wherever required
