Organization development (OD) is a deliberately planned effort to
increase an organization's relevance and viability. Vasudevan has
referred to OD as, future readiness to meet change, thus a systemic
learning and development strategy intended to change the basics of
beliefs, attitudes and relevance of values, and structure of the
current organization to better absorb disruptive technologies,
shrinking or exploding market opportunities and ensuing challenges
and chaos. OD is the framework for a change process designed to
lead to desirable positive impact to all stakeholders and the
environment. OD can design interventions with application of
several multidisciplinary methods and research besides traditional
OD approaches.
Ultraviolet-visible spectroscopy or ultraviolet-visible
spectrophotometry (UV-Vis or UV/Vis) refers to absorption
spectroscopy or reflectance spectroscopy in the ultraviolet-visible
spectral region. This means it uses light in the visible and
adjacent (near-UV and near-infrared (NIR)) ranges. The absorption
or reflectance in the visible range directly affects the perceived
color of the chemicals involved. In this region of the
electromagnetic spectrum, molecules undergo electronic transitions.
This technique is complementary to fluorescence spectroscopy, in
that fluorescence deals with transitions from the excited state to
the ground state, while absorption measures transitions from the
ground state to the excited state.
Mass Spectrometry is a technique that determines the molecular
weight (mass) and elemental composition of a compound accurately.
It records relative abundance (number of different kinds of ions)
and mass/charge (m/e) ratio. An advantage of Mass Spectrometry is
its ability to identify the unknown compounds using only pictogram
(10-12) amounts. Because ions are very reactive and short-lived,
their formation and manipulation must be conducted in a vacuum.
Atmospheric pressure is around 760 torr (mm of mercury). The
pressure under which ions may be handled is roughly 10-5 to 10-8
torr (less than a billionth of an atmosphere).
The eco-friendly solvent-free approach using microwave irradiation
opens numerous possibilities for conducting rapid heterocyclic
synthesis, via cycloaddition and cyclocondensation reactions, using
a variety of supported reagents on mineral oxides and phase
transfer catalysis conditions. The absence of solvent reduces
considerably the reaction time and generally improves the yields.
Due to the wide range of applications of microwaves, this method of
synthesis has been selected. Pyrazolines are also known to possess
antioxidant property wherein they scavenge free radicals which are
one of the causes for cell damage leading to several diseases. It
was our interest to synthesize the pyrazoline derivatives and
evaluate them for their antioxidant activity.
