"Green" Microemulsions and Nanoemulsions as Alternative Fuels
Combustion of water-containing diesel fuels results in a simultaneous reduction of soot and NOx-emissions, i.e. they partially avoid the so-called soot-NOx trade-off. In the frame of the present work new temperature invariant, highly efficient fuel microemulsions of the type water/antifreeze - diesel fuel - oleic acid/monoethanolamine/oleic acid diethanolamide containing up to 24 wt.% water with appropriate physical characteristics for commercial applications were formulated. As unexpected reward of the investigations on formulation of microemulsion fuels, novel water-in-fuel nanoemulsions (< 200 nm) were obtained featuring substantial reduction of surfactant content, an interesting economical aspect. Exhaust gas emissions, soot-structure and size distribution of water containing fuels compared to pure diesel fuel were analysed. The results show that using load-dependent water containing fuels yield a drastic reduction of soot up to 98 % (FSN) as well as nitrogen oxide emissions up to 62 %.
"Molecules to Materials: Volume 2 Materials to Molecular Fragments"
This book is Volume-2 on the topic of "Molecules to Materials: Materials to Molecular Fragments". The consequences of HR PMR experimental studies on Single Crystalline Solid State resulted in the determination of the principal axes directions and principal components of proton shielding Tensor in a molecule. Significance of the results was the necessity to look into greater detail the inter molecular contribution and intra molecular contribution to proton shielding. These consisted of specific neighborhood contribution from other molecules within 100 Angstroms radius, as well as the contribution of the continuum at large from the entire span of the specimen volume and the specimen shape effects. Over the years, these bulk material consequences could be accounted for satisfactorily with classical magnetic dipole model, the advantage being that the method and this model itself could be found useful for intra molecular shielding tensor calculation. These intra molecular aspects are the considerations in this Volume -II, consists of the papers presented by this author at the Annual Sessions of the Indian Science Congress Association (Kolkata)during the period from year 2009, till 2017.

129 Xe Relaxation and Rabi Oscillations
This thesis describes longitudinal nuclear relaxation measurements of solid 129Xe near 77 K with previously unattainable reproducibility, and demonstrates differences in relaxation, dependent upon the way in which the solid is condensed. These results are directly applicable to the generation and storage of large quantities of hyperpolarized 129Xe for various applications, such as lung magnetic resonance imaging (MRI). The thesis features a sophisticated theoretical approach to these data sets, including modifications to a well-established Raman-phonon scattering theory that may explain the larger scatter in and discrepancies with previous work.

A antropometria como fator de previsão dos componentes motores baseados no desempenho
O desporto é uma atividade competitiva institucionalizada que implica um esforço físico vigoroso ou a utilização de capacidades físicas relativamente complexas por indivíduos cuja participação é motivada por uma combinação da satisfação intrínseca associada à própria atividade e das recompensas externas obtidas através da participação. De acordo com Webster, desporto significa diversão, divertimento ou recreação, um tempo passado agradável, um tempo passado ao ar livre, ou que tem um carácter atlético como a caça, a pesca, a corrida, o basebol, o bowling ou a luta livre. A ciência desempenha um papel importante em todos os domínios da vida humana. O progresso tecnológico durante o último século é o resultado do avanço da matemática, da física, bem como de outras ciências aplicadas. A educação física parece ter tomado um novo rumo sob a forma de ciências do desporto. As ciências do desporto, por sua vez, foram buscar o seu conteúdo e a sua metodologia a várias ciências de base. A educação física e o desporto, sendo uma parte integrante da educação, também sofreram o impacto dos avanços científicos. Pensa-se que várias palavras são possíveis fontes do termo "cricket". A mais antiga referência conhecida a este desporto data de 1598.
A brief overview of FGH and TDDVR methods and its Application
The field of spectroscopy and quantum dynamics of molecular systems with the effect of externally applied laser field has grown explosively in the past few decades. The quantum description of vibrational and ro-vibrational states is a subject of great interest because of the fundamental importance of intramolecular energy transfer in many areas of chemical dynamics. Now a days the theoreticians want to perform the dynamics of the larger molecular systems consisting with more internal degrees of freedom, in full complexity to mimic the real world problems. However, that is certainly impossible for larger systems with more than four atoms, organic molecules, for example. Hence, we consider computationally feasible model systems to make the calculation simpler and get feasible result. We would like to study the vibrational spectra of triatomic molecules by Fourier Grid Hamiltonian method in conjunction with the Lanczos recursion scheme. We have also investigated the dynamics of multi-surface multi-mode Hamiltonian representing polyatomic cations by parallelized time-dependent Discrete Variable Representation (TDDVR) method.
