Aims. We present a new list of thorium and argon emission lines in the visible obtained by analyzing high-resolution (R = 110, 000) spectra of a ThAr hollow cathode lamp. The aim of this new line list is to allow significant improvements in the quality of wavelength calibration for medium-to high-resolution astronomical spectrographs. Methods. We use a series of ThAr lamp exposures obtained wit...

The objective of this work has been the co-precipitation of the coating material Ethyl Cellulose (EC) and two natural extracts (IDOKI SCF Technologies), R1 and P1, using the Supercritical Antisolvent (SAS) precipitation technique with supercritical carbon dioxide (SC-CO2), in order to obtain active microparticles. EC is a hydrophobic material widely used for controlled delivery systems, sustain...

In the last decade, there has been a lot of focus on sustainable development in the electrical power industry to meet the growing energy demand. This has led to an increase in the integration of renewable energy sources (RES). In addition to being abundantly available, the RES offers advantages such as low environmental impact and increased social development of rural communities which are impe...

Many sites in the densely populated Indo-Gangetic Plain (IGP) frequently exceed the national ambient air quality standard (NAAQS) of 100 μg m for 24 h average PM10 and 60 μg m for 24 h average PM2.5 mass loadings, exposing residents to hazardous levels of particulate matter (PM) throughout the year. We quantify the contribution of long-range transport to elevated PM levels and the number of exc...

Aeolian process leads to the transportation and accumulation of sand particles that result in dune landforms. The structure shape dunes are driven by parameters interacting wind force material composition within. Cross-section profiles over will essay geomorphological through which steady state rate transport can be computed. National Aeronautics Space Administration’s novel satellite namely Ic...

The Thar Desert, a very inhospitable place, accommodates only plant species that survive acute drought, unpredictable precipitation, and those can grow in the limited moisture of sandy soils. Capparis decidua is among one of the few plants able to grow well under these conditions. This species is highly exploited and has been naturally taken, as local people use it for various purposes like foo...
