Polarizability of ferrocene derivatives from quantum mechanical delta-function potentials
Get PDF206-209The atomic bond and molecular polarizabilities of some ferrocene derivatives have been calculated using variational method and delta-function electronic wave functions. Scales have been presented, where the derivatives are classified in order of their polarization properties. Common trends and patterns of behaviour are recognized and discussed
Semi-empirical and <i>ab initio </i>studies on the structure and polarizability of <i>C<sub>60</sub>, </i>C<i><sub>70</sub> </i>and <i>C<sub>84</sub></i>
No full text687-692The polarizabilities
of a number of aromatic hydrocarbons and the three fullerenes (C60,
C70 and C84) have been calculated using a new empirical
approach based on the square of the sum of the atomic hybrid components(τ A)
as given by the relation α(abc)= (Å3) where the summation proceeds over
all atoms A= 1,2,3---, and N is the total number of electrons in the molecule. The
geometries have also been optimized

technique which gives more emphasis on
indigenous knowledge enable locals to do their
own appraisal, analysis and planning in the
participatory mode. In this study, for the
problem identification, problem-solution and
preparation of village development plan
SWOT analysis and PRA tools was used at
Bhargawan village of Satna district, India. The
rank-based quotient (RBQ) was calculated in
order to prioritize the identified problems and
their solution was given using problemsolution tree technique. Findings indicated low
land and water productivity, unavailability of
irrigation water, aira partha, Soil sickness with
Fusarium, mismanagement of animal waste and
crop residue as constraints faced by the farmers
of village. Constraints identified were
categorized as problems arising out of gaps in
research/extension activities in various
agriculture and allied sectors. Based on the
results and necessity of the villagers, scope for
research/extension and village agriculture
development programme/policy implications
was made. Village agriculture development
plan (VADP) of Bhargawan village will help the
policymaker/NGOs/State govt. in the planning
and management of soil, water and agriculture
