Opis:
This study is devoted to highlighting the temporal trends and spatial variations in the concentration and growth of the major religious groups in India with special reference to the Sikh population. Such studies are gaining importance with the increasing penetration of both the religion and castecomposition in the political environment of the country. Although religious and caste interventions in politics are prevalent in all the elections, these become stronger as we move down from Parliamentary to Panchayat elections in which the voting pattern changes in favour of religion and caste groups. It has been observed that the share of Muslim population increased by 5.96% between 2001 and 2011, while it declined in the case of all other communities and the maximum decline (-8.02%) was noticed in the case of the Sikh population with the lowest share among all the major religious communities in India. The Sikh population also recorded the lowest growth rate of 8.42% against 24.65% and 16.76% witnessed by Muslims and Hindus respectively between2001 and 2011. The study is based on the religious data released by the Census of India.

Opis:
The increasing concern for the safety and sustainability of structures is calling for the development of smart self-healing materials and preventive repair methods. This research is carried out to investigate the extent of self-healing in normal-strength concrete by using Sporosarcina aquimarina – NCCP-2716 immobilized in expanded perlite (EP) as the carrier. The efficacy of crack-healing was also tested using two alternative self-healing techniques, i.e. expanded perlite (EP) concrete and direct introduction of bacteria in concrete. A bacterial solution was embedded in EP and calcium lactate pentahydrate was added as the nutrient. Experiments revealed that specimens containing EP-immobilized bacteria had the most effective crack-healing. After 28 days of healing, the values of completely healed crack widths were up to 0.78 mm, which is higher than the 0.5 mm value for specimens with the direct addition of bacteria. The specimen showed a significant self-healing phenomenon caused by substantial calcite precipitation by bacteria. The induced cracks were observed to be repaired autonomously by the calcite produced by the bacteria without any adverse effect on strength. The results of this research could provide a scientific foundation for the use of expanded perlite as a novel microbe carrier and Sporosarcina aquimarina as a potential microbe in bacteria-based self-healing concrete.
