Environmental forensics of the X-press pearl disaster: Uncovering the internal micro-structural transformations in marine microplastics.

The MV X-Press Pearl (XPP) maritime disaster on May 25, 2021, released approximately 75 billion microplastic (MP) nurdles into the Indian Ocean and degraded due to the elevated temperatures, a cocktail of chemicals, physical abrasions, and environmental factors. While degradation-induced surface-level chemical and morphological changes were well documented, internal degradation remains largely unexplored. This study highlights the utilization of high-resolution optical coherence tomography (OCT) as a purely non-destructive imaging modality to discover profound internal alterations in the micrometer range, such as internal hollow regions, cracks, and voids in MP nurdles subjected to different degrees of degradation.

Welfare Issues on Dairy Farms in Tripura, India, as Identified Through On-Farm Inspection.

With the aim of identifying the welfare issues of dairy animals in field conditions in Tripura state, the study was carried out across 3 purposively selected districts having maximum cooperatives and from each district 8 cooperative societies were selected at random, totaling 120 farmers (5 farmers from each cooperative). Farmers were grouped by herd size i.e.

Exposing the essence: evaluating quality, readability, trustworthiness, and understandability of information on depression in YouTube videos and the web.

Background: Depression is a common mental disorder worldwide. The internet offers a wide range of digital resources on depression, but its credibility is sometimes doubted due to the potential for erroneous information, which can worsen the stigma surrounding mental health and deter individuals from seeking professional services.

Aims: This paper aimed to analyze the contents of depression on Google and YouTube videos.

Improved flame retardancy of cotton fabric by crosslinking 3-hydroxyphenyl phosphinyl propanoic acid using 1,2,3,4-butane tetracarboxylic acid.

Cotton fabric was treated with commercially available 3-hydroxyphenyl phosphinyl propanoic acid (3HPP) as a flame-retardant agent, in combination with 1,2,3,4-butanetetracarboxylic acid (BTCA) as a cross-linking agent and dicyandiamide (DCDA) as a catalyst for esterification. The phosphorus moiety successfully bonded with both the cotton fibres and the cross-linking agent, as confirmed by FTIR and XPS analyses. The concentration of 3HPP in the padding bath was varied from 1 % to 10 %.
