This study documents and interprets different modes of a salutation, namely 'poothara (also puttara) thozhal / vandanam', across various styles of kalarippayattu, a traditional martial art and healing system, popular in the southern states of India.

The right stepping generates a restraining bend in the dominantly left-lateral shear zone. Such fault stepovers can localise strain and act as loci for seismic ruptures.

This article charts out the evolution of conservation social sciences alongside the evolution of The Social Science Working Group under Society of Conservation Biology (SCB).

Folding and unfolding of proteins is a biologically important topic as many neurological diseases involve misfolding of proteins. Here we have used the technique of X-ray crystallography to characterise the early stages of unfolding of the protein lysozyme purified from hen egg-white. The results when compared with our earlier studies reveal, for the first-time, the possibility of protein unfolding to start from a unique point. If true, this would enable engineering of proteins and drugs to prevent neurological disorders.

 In this study, a modular radial flow annular reactor using the strontium bromide hexahydrate-monohydrate conversion reaction is designed for long-term energy storage, and performance analysis is conducted for eight cities from the Indian Himalayan Region, each with distinct meteorological characteristics, to evaluate the system’s suitability.  The year-long charging and discharging efficiencies are nearly location-independent, with consistent values of ∼35 % and ∼74 %, respectively. The system configuration with direct solar heating capabilities exhibits better overall system efficiency and economic feasibility, with the levelized cost of heating in the range of INR 33–51/kWh. The heating cost is higher than that of conventional electric systems but is competitive with diesel-based heating (>INR 40/kWh).

Anthropogenic greenhouse gas emissions significantly impact the middle and upper atmosphere. They cause cooling and thermal shrinking and affect the atmospheric structure. Atmospheric contraction results in changes in key atmospheric features, such as the stratopause height or the peak ionospheric electron density, and also results in reduced thermosphere density. These changes can impact, among others, the lifespan of objects in low Earth orbit, refraction of radio communication and GPS signals, and the peak altitudes of meteoroids entering the Earth's atmosphere. Given this, there is a critical need for observational capabilities to monitor the middle and upper atmosphere. Equally important is the commitment to maintaining and improving long-term, homogeneous data collection. However, capabilities to observe the middle and upper atmosphere are decreasing rather than improving.
