Structural response to the magnetic pre-ordering in LiFeSi
We investigate the temperature evolution of the structural parameters of potential ferrotoroidic LiFeSi2O6 compound across structural and magnetic phase transitions. The structural transition, TS is ~230 K and the paramagnetic to antiferromagnetic transition, TN is ~18 K. The lattice parameters exhibit unusual temperature dependence and based on its behaviour, the experimental results can be divided into 3 regions. In region I (300 K to 240 K), the cell parameters are mainly governed by mere thermal effect. As the compound enters region II (below 240 K to 30 K), the lattice parameters show non-linear behaviour. In this region, the exchange pathways that lead to the magnetic interactions within and between the Fe–Fe chains do not show significant response. The region III (below 30 K) is dominated by the magnetic contribution where we observe setting up of both intra and inter-chain magnetic interactions which could be the possible reason for the ferrotorodic behaviour observed in this compound. We believe that the present results will be helpful in understanding the evolution of spin rings that gives rise to net toroidal moment and its consequent properties
Abstracts of International Conference on Innovations in Business Management
This book contains abstracts of the various research ideas of the academic community and practitioners of management presented at the International Conference on Innovations in Business Management (ICIBM 2020). The researchers have contributed toward various themes of the conference such as sustainable economy, supply chain, women-empowerment, export-import, microfinance, government policies, etc. We strongly believe that it will open up further scope for in-depth research in various disciplines of business management. Best wishes to the participants to have detailed discussions on the above-said wide range of areas.

Immune regulation during chronic visceral leishmaniasis
Visceral leishmaniasis is a chronic parasitic disease associated with severe immune dysfunction. Treatment options are limited to relatively toxic drugs and there is no vaccine for humans available. Hence, there is an urgent need to better understand immune responses following infection with Leishmania species by studying animal models of disease and clinical samples from patients. Here, we review recent discoveries in these areas and highlight shortcomings in our knowledge that need to be addressed if better treatment options are to be developed and effective vaccines designed
