Abstract:
Chapter 1 presents a brief note on the state at which the construction industry
stands at present, bringing into focus the significance of the critical study. Relevance
of the study, area of investigation and objectives of the study are outlined in this
chapter. The 2nd chapter presents a review of the literature on the relevant areas.
In the third chapter an analysis on time and cost overrun in construction
highlighting the major factors responsible for it has been done. A couple of case
studies to estimate loss to the nation on account of delay in construction have been
presented in the chapter. The need for an appropriate estimate and a competent
contractor has been emphasised for improving effectiveness in the project
implementation. Certain useful equations and thoughts have been formulated on this
area in this chapter that can be followed in State PWD and other Govt. organisations.
Case studies on project implementation of major projects undertaken by
Government sponsored/supported organizations in Kerala have been dealt with in
Chapter 4. A detailed description of the project of Kerala Legislature Complex with a
critical analysis has been given in this chapter. A detailed account of the investigations carried out on the construction of International Stadium, a sports project
of Greater Cochin Development Authority is included here. The project details of
Cochin International Airport at Nedumbassery, its promoters and contractors are also
discussed in Chapter 4.
Various aspects of implementation which led the above projects successful have
been discussed in chapter 5. The data collected were analysed through discussion and
perceptions to arrive at certain conclusions. The emergence of front-loaded contract
and its impact on economics of the project execution are dealt with in this chapter.
Analysis of delays in respect of the various project narrated in chapter 3 has been done
here. The root causes of the project time and overrun and its remedial measures are
also enlisted in this chapter.
Study of cost and time overrun of any construction project IS a part of
construction management. Under the present environment of heavy investment on
construction activities in India, the consequences of mismanagement many a time lead
to excessive expenditure which are not be avoidable. Cost consciousness, therefore has
to be keener than ever before. Optimization in investment can be achieved by
improved dynamism in construction management. The successful completion of
coristruction projects within the specified programme, optimizing three major attributes
of the process - quality, schedule and costs - has become the most valuable and
challenging task for the engineer - managers to perform. So, the various aspects of
construction management such as cost control, schedule control, quality assurance,
management techniques etc. have also been discussed in this fifth chapter.
Chapter 6 summarises the conclusions drawn from the above criticalr1 of rhajor
construction projects in Kerala.

Abstract:
The current scenario of coordination chemistry is witnessing the exploitation
of coordination bonds and noncovalent interactions to generate self-assemblies of
various dimensions having not only aesthetic values but also countless applications
and that paved way for supramolecular chemistry/crystal engineering. Most of
such fascinating work employs Schiff bases obtained by the condenzation of an
amine and a carbonyl compound. The use of diamines in the synthesis of highnuclearity
complexes utilizes the bridging capacity of phenoxo atoms. Whereas in
the case of N2O donor tridentate Schiff bases (N-substituted diamines with
salicylaldehyde or its derivatives), coligands are employed to generate structures of
variable composition apart from satisfying the coordination number. Among the
various coligands known, pseudohalides (azido, cyanato, thiocyanato, dicyanamido)
deserve special attention on account of its versatile modes of binding. In addition
to the structural variety, such Schiff base complexes have its signature in the field
of catalysis, luminescence, gas adsorption and magnetic materials which make the
arena conspicuous. The recognition of plasticity of copper(II) metal with respect to
its coordination number and its ubiquitous nature as active sites in many metalloenzymes
fuelled us to work with this metal. The results of our efforts to explore
the role of various interaction forces constitute the subject matter of the thesis
entitled “Crystalline architectures of copper(II) complexes derived from halogen
substituted carbonyl compounds: Interplay of covalent and non-covalent forces”.
The work embodied in this thesis was carried out by the author in the Department of
Applied Chemistry, CUSAT, Kochi, during the period 2011-2016 and is divided into
eight chapters.

Abstract:
Thiosemicarbazones have emerged as an important class of ligands
over a period of time, for a variety of reasons, such as variable donor
properties, structural diversity and biological applications. Interesting as
the coordination chemistry may be, the driving force for the study of these
ligands has undoubtedly been their biological properties and the majority
of the 3000 or so publications on thiosemicarbazones since 2000 have
alluded to this feature. Thiosemicarbazones with potential donor atoms in
their structural skeleton fascinate coordination chemists with their versatile
chelating behavior. The thiosemicarbazones of aromatic aldehydes and
ketones form stable chelates with transition metal cations by utilizing both
their sulfur and azomethine nitrogen as donor atoms. They have been
shown to possess a diverse range of biological activities including
anticancer, antitumor, antibacterial, antiviral, antimalarial and antifungal
properties owing to their ability to diffuse through the semipermeable
membrane of the cell lines. The enhanced effect may be attributed to the
increased lipophilicity of the metal complexes compared to the ligand
alone.

Abstract:
Supra molecular architectures of coordination complexes of liydrazones
through non covalent interactions have been explored. Molecular self—assernbly
driven by weak interactions such as hydrogen— bonding, K '”T[, C-1-I‘ "TE, van
der Waals interactions, and so forth are currently of tremendous research
interest in the fields of molecule based materials. The directional properties of
the hydrogembonding interaction associate discrete molecules into aggregate
structures that are sufficiently stable to be considered as independent chemical
species. Chemistry can borrow nature’s strategy to utilize hydrogen-bonding as
Well as other noncovalent interactions as found in secondary and tertiary
structures of proteins such as the double helix folding of DNA, hydrophobic
selflorganization of phospholipids in cell membrane etc. In supramolecular
chemistry hydrogen bonding plays an important role in forming a variety of
architectures. Thus, the wise modulation and tuning of the complementary sites
responsible for hydrogen—bond formation have led to its application in
supramolecular electronics, host-guest chemistry, self-assembly of molecular
capsules, nanotubes etc. The work presented in this thesis describes the synthesis and
characterization of metal complexes derived from some substituted
aroylhydrazones. The thesis is divided into seven chapters.

Abstract:
Earlier studies on measurement of customer satisfaction are based on either transaction specific or overall approaches. The transaction specific approach evaluates customer satisfaction with single components in the whole purchase process but the overall satisfaction was based on all the encounters or experiences to the customer throughout the purchase process. Consumers will comment on particular events of their purchase process when asked about transaction-specific satisfaction and they will comment their overall impression and general experiences in overall satisfaction (Bitner & Hubbert 1994) Through a critical review on the literature, it has been identified a new approaches to customer satisfaction, say, cumulative approaches that can be more useful than overall and transaction specific approaches for strategic decision making (Fornell et al 1996). The cumulative approach to customer satisfaction doesn’t study earlier due to the difficulty in operationalization of the concept. But the influencers of customer satisfaction are context specific and the prevailing models doesn’t give the sources of variations in the satisfaction, the importance of cumulative approaches to customer satisfaction has emerges that lights to a new research. The current study has focused to explore the influencers of overall customer satisfaction to form individual elements that can be used to identify the cumulative customer satisfaction.

Abstract:
The scope of the work was to synthesis few biologically active derivatives
of curcumin. The derivatives were prepared by altering the keto-enol centre of
curcumin by various reagents. This particular reaction centre for preparing
derivative was selected keeping in mind the controversy regarding the major site
responsible for antioxidant mechanism of curcumin. Most of the mechanistic study
done earlier was by varying the constituents in one or both of the phenol ring
present in the curcumin. The alterations at the keto-enol moiety may throw an
insight into the role of the diketo moiety towards the antioxidant mechanism. Since
recently curcumin has been suggested as a chemotherapeutic agent for various
ailments, we also decided to check the DNA intercalating property of the
derivatives synthesised.

Abstract:
There are a large number of commercial examples and property advantages of immiscible elastomer blends.73 Blends of natural rubber (NR) and polybutadiene (BR) have shown various
advantages including heat stability, improved elasticity and abrasion resistance. Ethylene-propylene-diene-rubber (EPDM) blended with styrene-butadiene rubber (SBR) has shown improvements in ozone and chemical resistance with better compression set properties. Blends of EPDM and nitrile rubber (NBR) have been cited as a compromise for obtaining moderate oil and ozone resistance with improved low temperature properties. Neoprene (CR)/BR blends offer improved low temperature properties and abrasion resistance with better processing characteristics etc. However, in many of the commercial two-phase elastomer blends, segregation of the crosslinking agents, carbon black or antioxidants preferentially into one phase
can result in failure to attain optimum properties. Soluble and insoluble compounding ingredients are found to be preferentially concentrated in one phase. The balance of optimum curing of both phases therefore presents a difficult problem. It has been the aim of this study to improve the
performance of commercially important elastomer blends such as natural rubber (NR)/styrene-butadiene rubber (SBR) and natural rubber/polybutadiene rubber (BR) by industrially viable procedures

Abstract:
The customary laws of Union Territory of Lakshadweep islands are a
challenge for judicial institution as well as administrative machinery. With the
peculiarities of socio-legal institutions, Lakshadweep system stands apart from the
mainstream of legal systems in India. How far do the charismatic modernisation
trends flowing into the Lakshadweep society affect the people already protected
by the uncodified laws of the past? Many are the issues at this stage. This study
analyses them. It examines the growth, evolution and development of the legal
system in the islands vis-a-vis the administrative mechanism imposed by the
mainland ethos and culture.

Abstract:
As of 1999. the state of Kerala has 3210 offices of scheduled
commercial banks (SCBS). In all, there are 48 commercial banks
operating in Kerala, which includes PSBs, OPBs, NPBS. FBs, and
Gramin Banks. The urban areas give a complete picture of the
competition in the present day banking scenario with the presence
of all bank groups. Semi-urban areas of Kerala have 2196 and urban
areas have 593 as on March 1995.“ The study focuses on the
selected segments ofthe urban customers in Kerala which is capable
of giving the finer aspects of variation in customer behaviour in the
purchase of banking products and services. Considering the
exhaustive nature of such an exercise, all the districts in the state
have not been brought under the purview of the study. Instead. three
districts with largest volume of business in terms of deposits,
advances, and number of offices have been short listed as
representative regions for a focused study.
The study focuses on the retail customer segment and their
perceptions on the various products or services offered to them. Non
Resident Indians (NRIs), and Traders and Small—ScaIe Industries
segments have also been included in the study with a view to obtain
a comparative picture with respect to perception on customer
satisfaction and service quality dimensions and bank choice
behaviour. The research is hence confined to customer behaviour
and the implications for possible strategies for segmentation within
the retail segment customers

Abstract:
In the current study, epidemiology study is done by means of
literature survey in groups identified to be at higher potential for DDIs as
well as in other cases to explore patterns of DDIs and the factors affecting
them. The structure of the FDA Adverse Event Reporting System (FAERS)
database is studied and analyzed in detail to identify issues and challenges
in data mining the drug-drug interactions. The necessary pre-processing
algorithms are developed based on the analysis and the Apriori algorithm is
modified to suit the process. Finally, the modules are integrated into a tool to identify DDIs. The results are compared using standard drug interaction
database for validation. 31% of the associations obtained were identified to
be new and the match with existing interactions was 69%. This match
clearly indicates the validity of the methodology and its applicability to
similar databases. Formulation of the results using the generic names
expanded the relevance of the results to a global scale. The global
applicability helps the health care professionals worldwide to observe
caution during various stages of drug administration thus considerably
enhancing pharmacovigilance
