This work reports magnetic field direction dependent second magnetisation peak (SMP) anomaly in single crystals of oxygenated [Formula: see text] for [Formula: see text] ab. Detailed investigations on crystal A revealed the direction dependence of SMP anomaly at temperatures below 25 K, above which the direction dependence vanishes. The state of spatial order of the vortex lattice was found to be correlated to the vortex lattice symmetry that underwent a change at certain fields and was captured via single flux jumps observed in the third and fifth quadrant of magnetisation hysteresis loops.

The synthesized samples were characterized by XRD and then FTIR techniques for structural besides compositional analysis. The approximate value of bandgap found out by NBE values of PL spectra showed a decrease in bandgap with doping.

- The Western Ghat region of Kerala has rich biodiversity that supports tick populations, which carry the Kyasanur Forest Disease virus (KFDV), known to cause hemorrhagic fever or "monkey fever."
- Tick infestations are common in local livestock, as these animals often graze in nearby forests, leading to increased risk of farmers contracting tick-borne diseases.
- While KFDV is widespread, data on other related viruses like CCHFV and GANV is limited, though a small percentage of livestock showed CCHFV exposure, indicating the need for further research and surveillance to identify disease hotspots.
Article Synopsis
- The degradation of larger plastic debris into microplastics (MPs), which are less than 5 mm in size, has been driven by natural factors like wind, waves, UV exposure, and biological action, leading to their wide presence in marine environments, including the Arctic Ocean.
- Research on MPs has focused more on water columns and marine life rather than sediment, making studies on sedimentary MPs in Arctic regions, particularly Kongsfjorden, less common.
- In Kongsfjorden, sediment analysis showed MPs present at three sampling sites, with a maximum of 24 MPs/kg, predominantly consisting of high-density polyethylene (HDPE), indicating a need for further study to determine their sources and environmental impacts.
We present the first study of microplastics in the sediments of Vembanad Lake, a Ramsar site in India. Microplastics are emerging pollutants of increasing environmental concern with a particle size of <5 mm, which originate from successive degradation of larger plastic debris or are manufactured as small granules and used in many applications. The impact of microplastics pollution on the environment and biota is not well known.
