The COVID-19 pandemic prompted unprecedented public health measures, including lockdowns that forced educational institutions to transition from conventional learning (CL) to online learning (OL). This shift significantly impacted disciplines like social work, which rely heavily on practical and fieldwork experiences. This study aimed to evaluate the impact and effectiveness of OL versus CL for MSW students across 12 states in India.

Article Synopsis
  • - The study examined the G × E interaction and stability of 14 sugarcane clones over two years and four locations in Uttarakhand, focusing on cane yield (CY) and sugar yield (SY) at various growth stages.
  • - Significant differences were found among clones, environments, and their interactions, and the GGE biplot method was used to analyze genotype stability, revealing top-performing clones for both CY and SY.
  • - Clone CoPant 16222 emerged as a strong candidate due to its high yield and stability, suggesting it could be recommended to farmers for improved productivity.

In the present work, iron nanoparticles were synthesized in the α-FeO phase with the reduction of potassium hexachloroferrate(III) by using l-ascorbic acid as a reducing agent in the presence of an amphiphilic non-ionic polyethylene glycol surfactant in an aqueous solution. The synthesized α-FeO NPs were characterized by powder X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, atomic force microscopy, dynamic light scattering, energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and ultraviolet-visible spectrophotometry. The powder X-ray diffraction analysis result confirmed the formation of α-FeO NPs, and the average crystallite size was found to be 45 nm.

Rock varnishes are known to be fine, dark, glossy submicron films found in deserts bare rock surfaces. The oxides and hydroxides of manganese and iron bind together the clay minerals present in the varnish layer. The processes of oxide-hydroxide accumulation at varnish sites are due to iron and manganese oxidizing bacteria which may require clay minerals for additional nutrition.

The complex process of nanoparticle formation in an aqueous solution is governed by kinetics and thermodynamic factors. This paper describes a room-temperature growth kinetic study and evaluation of thermodynamic activation parameters of monodispersed silver nanoparticles (AgNPs) synthesized in alkaline medium by chemical reduction method using AgNO as a source of Ag ions and tannic acid (TA) as a reductant (reducing agent) as well as a capping or stabilizing agent in the absence of any other external stabilizer. A simple and conveniently handled reaction process was monitored spectrophotometrically to study the growth kinetics in an aqueous solution as a function of the concentration of silver ion, hydroxide ion, and TA, respectively.

Being a structural and catalytic cofactor in a number of biological pathways, copper accumulates in tumors owing to selective permeability of the cancer cell membranes. Copper(II) ion forms the active centers in a large number of metalloproteins. The coordination of Schiff's base ligands to the metal ion results in the high extent of increase in anticancer activity.

The roots of Ichnocarpus frutescens along with roots of Cissampelos pareira, Bauhinia vahlii and Ardisia solanacea are processed together and given orally to cure stomach cancer by the tribes of Chotanagpur and Santhal parganas of Bihar, India. In vitro anticancer activity of the residue from methanolic extract of roots of I. frutescens (MIF) and isolated triterpenes were evaluated by 3-(4, 5-dimethyl thiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay using MCF-7, BEL-7402, SPC-A-1 and SGC-7901 cancer cell lines.

Vitex glabrata (Verbenaceae) is commonly employed for the treatment of various ailments in traditional medicine. In this study, ethanol extract of Vitex glabrata (EEVG) was evaluated for the anti-inflammatory activity using carrageenan-induced paw edema and cotton pellet induced granuloma formation in rat models. EEVG showed significant anti-inflammatory activity in rats in dose dependant manner.
