Lithocarpus auriculatus (Hickel & A. Camus) Barnett (Fagaceae): A New Record for the Flora of India from the Eastern Himalayas

ABSTRACT Lithocarpus Blume is one of the largest genera of Fagaceae and is distributed mostly in tropical to temperate forests. Evidence on the occurrence of L. auriculatus (Hickel & A. Camus) Barnett, a Vulnerable species from the Kalimpong Himalayas of West Bengal, India was do...

Accessing Aerial Transformation of Arylmethanamines into Amides Using a Redox-Active Aryl-Substituted BIAN-Based Catalyst

Abstract The direct α-oxygenation of arylmethanamines to amides is a cornerstone transformation in organic synthesis; however, traditional methods suffer from harsh conditions, reactive reagents, and expensive transition metal catalysts. This study introduces a novel approach usi...

Phosphate solubilizing microbes from tea garden soil exhibit cellulose degrading and caffeine utilizing potential with high plant growth promoting activity

Tea plants thrive in acidic soils that often lead to phosphorus fixation, limiting its availability for plant absorption. Moreover, cellulose and caffeine deposits impair soil fertility by immobilizing nutrients and disrupting microbial activity, reducing yields unless addressed...

Emergent universe scenario in the modified Chaplygin gas: towards an exact solution and observational constraints

Abstract The modified Chaplygin gas (MCG) model is revisited to examine its capability in describing the complete cosmic evolution within a unified framework. The model is found to be consistent with observational constraints, including the cosmic microwave background (CMB) shift...

When rough I-convergent sequences fail to be rough I-Cauchy

This study builds on the research by Collins et al. [Topology Appl. 154 (2007) 2312-2322], Aytar [Numer. Funct. Anal. Optim. {29} (3-4) (2008) 291-303] and Kostyrko et al. [Real Anal. Exchange {26} (2) (2000/2001) 669-686] to introduce the concepts of forward (resp. backward) rou...
