Justification:
The Following
points indicate the DEVIATIONS from the original plan of work and require more support from the External Agency to be pursued
after the Termination of the Scheme.
The first
phase of the project implementation as envisaged in the original research proposal was to construct the Magic Angle Spinning
[MAS] Probe for the AC 300 NMR Spectrometer at the RSIC, NEHU for which it was plabnned to collaborate with NCL, PUNE. There
had been no change in this prime objective to provide the MAS facility nor any change in the requirement of the collaborative
effort.
However
there had been a change in the methodology and the materials due to the following turn of events:
1. The
main component for the construction of MAS assembly is the stator/rotor assembly and this part of it was supposed to have
been a stock available at NCL as much as it was used for the previously published MAS construction. Soon after the CSIR Scheme
of this PI at NEHU was sanctioned [by this time this was all efforts of two-year-before 01-01-2002] the situation prevailing
was that the stock of stator/rotor assembly at NCL has become not so much of available material for this purpose and efforts
to contact the various manufacturers for procuring the spare part stator/rotor took about 2 months. And propmtly replies were
received that no manufacturer would be selling this item as listed component except as a spare assembly for their original
MAS Probes procured. This sitruation was a set back but, effort by this PI in trying to contact Bruker BioSpin {Sales/Marketing Division} on this matter resulted in an optimistic turn since the Bruker BioSpin
exhuded such an understanding in this context that they were making possible for this PI to procure the Bruker's original
Mechanical assembly with stator/rotor at the costs amounting to reasonably within the reach of the equipment grant in this
Scheme. This scene was neither known before as a possibility, nor it is any compromise of the original plan as portrayable
by the descriptions below:
2. The
fact at RSIC, NEHU is that the entire maintenance and operational aspects have to be with the available technical assistants
at RSIC, who do not have experience in the Solid State NMR aspects either instrumentational or the Magnetic Resaonance Technicalities.
If a probe constructed entirely indigenously is brought before them, then to make them get used what another user [though
it is this PI with reasonably weell equipped with the required prerequisites to use and impart training] has to provide on
his own Reasearch project [and not a unit procured from the manufacturers weell known to them with familiar service personnel]
would have been an inexplicable hurdle. This has now turned out to be nonexistent becuase the mechanical assembly as they
would be handling would be the familiar Bruker design like that of the present liquid-state NMR probe setup. No longer there
is any requirement for trying to acquire the stator/rotor assembly separately. This is a
special offer from Bruker BioSpin for the research project of this PI.
3. These
developments could take shape at a much slower rate than what otherwise would have been including the delays of having to
go through the acquiring of purchase committee approvals for the required import of this assembly.
The above
has the major contribution in changing the course of implementation to this stage. Since the scheme was approved only two
years after the first initiatives, at the outset while commencing the scheme on 01-01-2202 the PI had a rather gloomy picture at the time of receiving the sanction of the scheme than this cheerful turn.
That
no staff [JRA/SRA/RA] could be appointed in this scheme is a trend quite obvious and explainable, given the experience of
this PI during the early stages of the installation and utilization of the facility at this NMR Sysytem in NEHU, Shillong.
But, this would be the enthusiasm on this project was not in any way a foregone conclusion eventhough there are reasons to
state for this continued nonavailablity of technically motivated research scholars. This state of the technical know how had
prompted this PI to set the trends for an "INNOVATIVE PROGRAMME" initiatives
on Magnetic Resonance Spectroscopic Techniques. Thus unintended outcome is the drafting of a viable course curriculum and
get this also reviewed by the expert committee of the UGC is an unstated outcome of the efforts to implement the CSIR Research
Scheme on providing a reinforced Magnetic Resonance Facility at this University.
The
following enumeration of the Work Done During in this scheme indicates that for the changed Plan of Work and the progress
made thus would require a much longer evolution period under the support of the CSIR so that a clear appreciation of the realization
of the Objectives in spite of the changes and how the support from the external agency has contributed necessarily to the
advantage of the host institution
Significant
progress has been made in implementing the first phase of the project, namely, the construction of the Magic Angle Sample
Spinning MASS probe accessory for the AC 300 NMR Spectrometer at the RSIC, NEHU. The spontaneous special offer from Bruker
BioSpin to provide the basic mechanical assembly of the Probe (MASS) body has reduced the effort in acquiring good quality
material for the construction of the probe and have it designed and machined in a precision work shop.
During
the process of implementing this project, particularly because of the experiences gained
while trying to appoint a staff in the project, a necessity arose for working out a durable curricular contents for a
graduate programmes, appropriate and comptible with the average student level, so as to impart a capability to them to gain
the technical know-how for using the Magnetic Resonance Spectroscopy at a rate commensurate with the rapidly advancing technological
provisions for the utilization. Aconsiderable progress has been made in this direction, and the course-curricular structure
drafted out by this PI under the frame work of the INNOVATIVE PROGRAMME of the University Grants Commission has been reviewed
by an Expert committee of the UGC and found adequate for a PG level course on Magnetic Resonance Spectroscopic Technique.
However, the PI would be able to surge forward only if a Bench top Nuclear Magnetic Resonance spectrometer Unit could be procured
as a supplementary unit to the existing FT NMR AC 300 Spectrometer at the University. This requirement of a durable Syllabus,
though was under the consideration since a long time, did gain the necessary emphasis during the course of implementing ths
CSIR Project. This activity was not explicitly indicated as a specific phase in the objective of the CSIR research proposal.
Nevertheless, implicit is that advantages accrued due to the support of the CSIR towards the overall need for improving the
infra structure facilities.
This
effort would go a long way in trying to impress on the users of the RSIC facility about the MASS technique and its use in
effectively extracting structural informations on systems which are hitherto being studied only in liquid state NMR. This
would be contributing to the lasting benefit of the CSIR Scheme which would continue to accrue even after the termination
of the CSIR project. While evolving this course structure, the other explicitly stated phases of the CSIR Schemes have implicitly
progessed without a necessity for any chronological sequence to implement the phases in the sequence as listed out in the
priginal research proposal.
The effort
to make progress on the results, which were obtained for the NMR measurements made at the TIFR, Mumbai during August 2003
with the VARIAN UNITY 600MHz NMR Spectrometer, have gained in their significance in view of the contributions made by this
PI in the National and International Symposia and Conferences on NMR. These trends seem to be furher substantiated by what
is being currently reported in literature as clarifications on interpretations of chamical shifts and induced fields.
These
effectively pave the right way for the use of the MASS facility [phase 1 of the CSIR Research scheme] when the construction
is completed for use.
The
folllowing is a description of the Nature of the work yet to be done should indicate to the Funding External Agency what could
really be the credibility that the Funding Agency can look for when this task is accomplished, from the point of view of the
what acrrued till now due to this CSIR Research Scheme
The electronic
components required for the tuning of the sample coil of the MASS probe have to be acquired and it is known now that these
have to be imported and are not avalable as listed items for sale by the manufacturers of the MASS probes. This would require
considerable effort to find components available from General Electronic Component suppliers that match the specifications
of component as required for a specialized instrument like MASS probe.
There
are several aspects of the present FT NMR Spectrometer System [the AC 300 at RSIC, NEHU] which have to be looked into since
only on the basis of the Working AC 300 system, the constructed probe would become useful. Or else CSIR may have to find an
alternative placement for this MASS probe unit if its construction is completed since the cost of this import item exceeds
Rs. 3 lakhs. This may not be a difficult task since this is a collaborative effort with NCL,Pune where there are requirements
for probes of this type and where there are several FT NMR systems already functional.
As
listed out in the last page of the Website URL: https://saravamudhan.tripod.com/csir_schm_sa/ it is essential to procure software packages which are for structure-prediction-types based on chemical shift data. Thus
the packages are essentially (i) Data bases of known spectra and chemical shifts (ii) packages enabling calculation of Chemical
shifts of nuclei in molecules using theoretical procedures. Acquiring of these packages would require utilization of funds
under appropriate head of accounts. The project originally submitted did not include the cost of these soft wares since as
originally intended if a staff could have been appointed, the scholar would have had to spend the time in exclusively the
first phase of the work since this requires acquiring skills in electronic instrumentation aspects which is not imparted as
a matter of routine in the regular PG level curriculum. Since the effort to attend to the training of a staff was absent,
the PI could spend time on the effort to look out for software packages which meet the specifications to be handled by, technical
assistants to start with to the extent of maintaining PCs and Workstations supporting these soft wares as part of the facility
and let the qualified assigned users to avail these software facilities. Since it is possible to find scientists handling
such soft wares near this Centre for their requirements making this as a facility part of NMR facility in a University is
a different trend which requires more efforts knowing the specialized package capabilities and the user environments which
would enable the use of the same.
Acquiring
data form Spectrometer on to another PC which is not a part of the spectrometer system of the manufacturers and processing
data is a trend which requires unconventional efforts and from the displays in the Conference pavilions and other resources,
reinforcements have to be added which would take shape when the first phase has been completed and the MASS probe accessory
is functional.
The work
which is being presented by this PI on INDUCED FIELD Calculations pertaining to magnetic moments and their effectiveness in
explaining the trends of observed chemical shifts [ http://saravamudhan.tripod.com ] , has certain relevance for the MASS
techniques. Particularly, while this PI was indicating the possible applications of these calculations in biological cells
with different susceptibilities inside (inner compartments) and outside (outer compartments) the cell, these indications are
being substantiated as valid by some of the recent publications in the Journal "Magnetic Resonance in Medicine"{ Vol 51, Number
3, page 441,march 2004] and "Concepts in Magnetic Resonance" [Vol 18, pages 72-95, 2003]. This encouraging trend has to be
reinforced by this PIs intended trend of experiments [see the results reported in the webpage cited above, particularly the
spectra with capillary tubes inside a 5mm NMR tubes]. The collaborating Scientist at NCL had expressed interest in experiments
which this PI had been envisaging on magic angle spinning of liquid state samples for their consequences which are not very
far from what was being reported currently in leading journals.
The
present state of the PIs concerns on Induced Field effects and the Lorentz ellipsoids/spheres can be appreciated by the documentation
at the URL: http://geocities.com/saravamudhan1944/eenc_ampere_lille.html and the other links to web pages in that Webpage.
All these
at present which this PI has indicated can be realized by this PI only if the supportive measures to promote such interests
are reinforcively enhanced. However, along these indicated trends any appointed staff can be trained and with assistance from
resource persons at National NMR facilities in this country, the work can be constructively progressing. Hence it all depends
on the Host institutions' appreciation of the purposes and the invigoration by the Supporting external agencies, in the cause
of making this institution as part of the national stream. This coordination of the activities at this RSIC, with the National
Facilities at TIFR, Mumbai and IISC., Bangalore is what is to be aspired as a durable consequence of this CSIR Scheme at NEHU
with the collaboration of NCL, PUNE.
More
details would be possible in the Final Technical Report soon after the 31st December 2004. Hence this PI would reinforce further
the requirement of an Extension for this Scheme by one more year by trying to have a Plain paper application duly forwarded
to CSIR by the Head of Instituion.
The provision
of providing a durable curricular training on the spectroscopic techniques based on Magnetic Resonance phenomena would surge
forward if the Rs. 42 Lakhs required for the bench top models could be forthcoming as the Extra Equipment Grant. As an alternative the PI for this purpose should be requisitioning by a renewed application this amount
from the Rs 50 lakhs set forth as possible grants by UGC for purposes of the INNOVATIVE PROGRAMMES. An OUTPUT DATA to UGC
in the prescribed form would be sent indicating the situation by this PI as a provisional measure for an approval to be sought
as coordinator of the envisaged programme.
