The present study aims to describe and bring out the tectonic nature of Ijai watershed in parts Kangpokpi, Tamenglong Noney districts Manipur. has an area 184.0 Km2which is also tectonically active as depicted by analysed values different geomorphic indices like SLK index, Valley Floor Width Height ratio (Vf),Transverse Topographic Symmetry (T), Drainage Basin Asymmetry (AF), Elongation Ratio (...

The fracture deformations often result in linear morphological elements (lineaments, valleys) on the surface. In many cases, direction of lineaments and valleys can be well followed by strike geological structural elements. Therefore, conclusions drawn from these directions for regional tectonic processes. Our work aimed to analyse relationship between valley lineament network south-eastern par...

The weakly electric fish from the main channel of the Amazon river, Sternarchogiton nattereri, offers a striking case of morphological variation. Females and most males are toothless, or present only few minute teeth on the mandible, whereas some males exhibit exaggerated, spike-like teeth that project externally from the snout and chin. Androgens are known to influence the expression of sexual...

Nitrogen (N) is important for the growth of crops. Leaf nitrogen content (LNC) serves as a crucial indicator of the growth status of crops and can help determine the dose of N fertilizer. Laser-induced fluorescence (LIF) technology and the reflectance spectra of crops are widely used to detect the biochemical content of leaves. Many vegetation indices (VIs) and fluorescence parameters have been...

BTEX (benzene, toluene, ethylbenzene and xylene) concentrations, factors affecting their levels, and the exposure risks related to these compounds were studied in waterpipe (Ghalyun/Hookah) cafés of Ardabil city in Islamic Republic of Iran. 81 waterpipe cafés from different districts of Ardabil city were selected and their ambient air was monitored for BTEX compounds. Air samples were taken fro...

Sustainable development has always been the objective of many fields, including the tourism and transportation sector. However, a major part of this sector, the airline industry, deals with many negative impacts, such as air pollution, noise, CO2 emission, and labor practice. Corporate social responsibility (CSR) is a strategic business activity that can enhance the sustainability of the airlin...

The Palmer Drought Severity Index (PDSI) was calculated globally using gridded monthly air temperature and precipitation. From 1900 to 1995, there are large multiyear to decadal variations in the percentage areas in severe drought (PDSI < −3.0) and severe moisture surplus (PDSI > +3.0) over many land areas while secular trends are small. Since the late 1970s, however, there have been some incre...
