The need to find a way forward standardize protocol for methods and accurate assessment of led carrying out this investigation comparing variation concentration using soil profile (by genetic horizon, SP) column layers, SC) based approaches. samples were collected according horizons (H1, H2, H3, H4) by following (SP) approach data (at 0–30, 30–60, 60–90...

Abstract Agroforestry is an alternative land use practice that holds promise for societal benefits and the attainment of ecosystem sustainability. The objectives this study were to evaluate tree diversity, carbon sequestration, soil pool, oxygen production rice productivity under traditional agroforestry systems at different elevations in Garhwal Himalayan region India. Tree sequestration quantified by field measurements (using 0.04 ha quadrats) subsequent calculations. Rice was assessed...

Abstract This study includes a comparative investigation to analyze the phytochemical composition, nematicidal efficacy, in vitro AChE inhibitory activity, and molecular docking of Leucosceptrum canum . (LC) extracts. Various polarity solvent extracts including hexane (LCHE), dichloromethane (LCDE), methanol (LCME) were prepared from LC aerial parts using Soxhlet extraction. Phytochemical analysis was done GC‐MS technique identify quantify presence bioactive compounds revealing that LCHE is...

Digitalis purpurea L. is traditionally valued for its cardiac glycosides, but pesticidal properties remain underexplored. This study evaluated nematicidal efficacy against Meloidogyne incognita, focusing on acetylcholinesterase (AChE) inhibition as a potential mechanism. Extracts obtained using Soxhlet extraction with hexane (DPHE), dichloromethane (DPDE), and methanol (DPME) were analyzed via GC‐MS. DPHE contained fatty acids, including hexadecenoic acid (20.38%) linoleic (14.43%). DPDE was...

Background Wave reflections, which are increased in patients with heart failure preserved ejection fraction, impair diastolic function and promote pathologic myocardial remodeling. Organic nitrates reduce wave reflections acutely, but whether this is sustained chronically or affected by hydralazine coadministration unknown. Methods Results We randomized 44 fraction a double‐blinded fashion to isosorbide dinitrate ( ISDN ; n=13), +hydralazine +hydral; n=15), placebo (n=16) for 6 months. The...

Potassium tert ‐butoxide was used to promote the arylation of imidazo‐fused heterocycles with diaryliodonium salts under transition‐metal‐free conditions. The described process proceeds through a radical pathway without addition oxidants or additives. A number functional groups were tolerated in this transformation, which provided good excellent yields products.

Pyrido[1,2- a]indoles are known for medicinally and pharmaceutically important compounds; however, the efficient synthetic routes scarce in literature. We report herein a convenient route to synthesize these molecules through indium-catalyzed transannulation of pyridotriazoles with arenes. A library compounds have been synthesized employing method developed various substituted pyrido[1,2- a]indole derivatives moderate good yields. The density functional theory study using...

Forests face a variety of threats in the modern era. Agroforestry systems, both traditional and introduced, have tremendous capacity for providing sustainable resources combating impact global climate change. Indigenous agroforestry forest land-use systems are important reservoirs biodiversity conservation ecosystem services, potential contribution to livelihood security rural communities. This study aimed assess tree diversity carbon stock adjoining forests along altitudinal gradients,...

Microalgae have emerged as a potential alternative for the production of many useful compounds like protein, carbohydrate and lipid. Lipid-rich microalgae are important rich source energy production. In order to commercially utilize production, lipid productivity should be enhanced. Keeping in view above-mentioned potentials microalgae, present study, we attempted display role chemical stimulants light growth Chlorella singularis (UUIND5). During investigations, effect varying photoperiods...

Tetrabutylammonium hydroxide catalysed oxidative amidation and thioamidation of benzylamines with oxygen elemental sulfur under solvent/metal/base-free conditions have been developed.
