Atmospheric black carbon aerosol: Long-term characteristics, source apportionment, and trends.

Black carbon (BC) aerosols play a very significant role in influencing air quality, climate, and human health. Large uncertainties still exist in BC emissions due to limited observations on the relative source contributions of fossil fuel (ff) combustion and biomass (wood fuel, wf) burning. Our understanding of long-term changes in BC emissions, especially their source apportionment, is sparse and limited.

Civet latrines in three habitats of a coffee dominated landscape of the Western Ghats biodiversity hotspot.

Civets are frugivorous animals in the Order Carnivora. They are relatively less shy towards people and anthropogenic habitats. It has been reported that the civets' preference of defecating in open sites enable them to be important seed dispersers of degraded forests and urban ecosystems of Asia and Africa.

Water-soluble chitosan salt as ecofriendly corrosion inhibitor for N80 pipeline steel in artificial sea water: Experimental and theoretical approach.

Chitosan, as a proficient biopolymer, has enormous potential as an ecofriendly corrosion inhibitor (CI), but their limited solubility restricts practical applications. Herein, an eco-friendly and water-soluble chitosan salt (CS) was utilized as a green CI on N80 pipeline steel in artificial sea water. Several structural and surface analytical tools were engaged in describing the characteristics of novel CS polymer.

infections with varied presentations and different antimicrobial susceptibility - A case series.

We report three sporadic infections by from Government Medical College Kozhikode in Kerala state, South India over a period of three years. Two cases were commenced in the community in immunocompromised children beyond the newborn period, but both recovered promptly. Another was a hospital-acquired meningitis in a newborn baby who developed neurologic sequelae.
