We hereby present the variability of fine particles (PM1 ≤ 1 micron) that has not yet been investigated under the influence of COVID-19-induced lockdown in three major cities of different climatic zones in India. We unfold the baseline level of PM1, a level to which the population is chronically exposed and extremely critical for epidemiologists for fixing health markers. This has been achieved using the saturation point methodology under fair weather conditions. The baseline level of PM1 for Delhi and Mumbai is found to be 13 µg m− 3 and 9 µg m− 3, respectively.

Many primate species show various behavioural and ecological adaptations to provisioning, one of which is the unusual occurrence of twins. Here, we report observations on two pairs of twins in the Puthuthottam population of lion-tailed macaques Macaca silenus in the Anamalai Hills of the Western Ghats and show that some lion-tailed macaque twins can survive under free-ranging conditions if they receive adequate care from their biological mother or another female.

The predictions on the disaster scenarios in the Himalayan states have come true. We are now witnessing the consequences of human interventions that have contributed to the intensity of disasters, impacting the lives and livelihoods of the people.

Thermochemical energy storage is emerging as a promising seasonal thermal energy storage technology. Strontium Bromide has recently become one of the most used salt hydrates for the salt-hydrate and moist airbased open thermochemical energy storage system. This article suggests that radial flow fixed bed reactors offer advantageous configurations owing to their lower pressure drop without compromising thermal performance.

This study experimentally investigates the scarcely studied stratified, oil-based sensible thermal energy storage (STES) tank, to examine the heat retention capability of Hytherm-600 silicone oil during the standalone period and its heat dispatchability during the discharging process. To conduct an experimental study on the thermic oil, a vertical cylindrical tank with a helical discharging coil fitted inside is used.

This study aimed to monitor long-term land use dynamics for understanding the natural forest integrity and intactness of the Rajiv Gandhi (Nagarhole) Tiger Reserve (RTR) pre- and post-declarations as TR. We employed multi-source data from Survey of India Toposheets (1:50 k), Landsat-7, and Sentinel-2A along with Global Ecosystem Dynamics Investigation (GEDI) vegetation canopy height (10 m) data, a high-spatial resolution CORONA (1970) images and temporal Google Earth Pro images for mapping and validation.

In this chapter, we reflect on our readings of female / feminist primatologists’ studies of female primates and our understandings of the gendered lives of bonnet macaques, a female-bonded nonhuman primate species, endemic to peninsular India. These two focal points provide us with insights into the complexities of individual identity in nonhuman societies and the situatedness of human and other-than- human gender identities in their lived worlds.

Nonhuman primates – mostly apes – are known to combine gestural units in non-random ways, but they do not make novel meaning with these combinations. In this paper, we investigated, for the first time, the structure and functions of gesture sequences in the naturally occurring communication of wild bonnet macaques, using analyses akin to ape gesture studies. We discuss our findings in the light of a possibility that primate gesture sequences, coordinating the flow of social interactions, may be evolutionary precursors to pragmatic gestures in human language.

A large-scale socio-cultural transition such as the ‘shift toward eCooking’ is a process (or a journey) rather than a destination. Apart from the business potential it offers, it would potentially create a large number of aware and educated citizens. Strengthening appliance and vessel manufacture would reinforce the country’s domestic MSME sector. Improved eCooking appliance safety culture would enhance manufacturers’ competitiveness (and also acceptability) globally.
