Objective: To evaluate the DPPH free radical scavenging activity of methanolic extract of different plant parts (stems, leaves and fruits) of S. surattense. Method: Methanolic extracts were tested for DPPH free radical scavenging activity, further total phenolic content (TPC), total flavonoidal content (TFC) and ascorbic acid content of S.surattense were analyzed through standard methods and their corresponding effect on antioxidant activity of the plant was assessed through correlation analysis. Results: The highest TPC (25.91 ± 0.803 mg gallic acid equivalents/g dry weight), TFC (17.7 ± 2.36 mg quercetin equivalent/g dry weight) and ascorbic acid content (0.746 ± 0.025 mg/gdw) were found in crude methanolic extract of leaves. The leaves also showed strong antioxidant activity. The highest radical scavenging effect was observed in leaves of S. surattense with IC50 = 22.936 ± 2.685µg/ml. Conclusion: Owning to these results, the S. surattense has the potential to serve as the source of alternative natural antioxidants and can be used as a medicine against the diseases caused by free radicals.
Rainfall monitoring during south west monsoon season both are very important ad crucial activity. It is important mainly because it is a boon for agriculture, a mirror for future for both social and economic activities and crucial for its measurements (ground as well as remote). In this current works authors made an attempt to know the performance of recently Space Application Centre (SAC), ISRO developed INSAT-3D improved rainfall algorithms (Hydro Estimator and corrected IMSARA) with actual ground based rainfall data by calculating the bias (Actual –Satellite) for each sub-division. The analysis is done for the southwest monsoon season -2021 in by calculating weekly, monthly and seasonal bias for each subdivisions of Indian domain. It is seen that both the algorithms behave similar fashion (both show increase or decrease, simultaneously) with actual data and mostly satellite overestimate with actual data ranges from ~ 20-40 mm. In some subdivisions bias reached within the range 40 -70 mm (except Konkan & Goa ). Almost 40 % of the subdivisions have bias within 0 to 20 mm range, however the variation on weekly, monthly or seasonal differs subdivision and magnitude-wise. Overall, both the algorithms captures and performance well the trends in weekly, monthly and seasonal accumulated rainfall values. Corrected IMSRA (IMC) algorithm perform slightly better (15-20 %) except heavy rainfall episodes during the monsoon season -2021. In both the heavy and very heavy rainfall cases Hydro Estimators pick up well and performs better (~ 10 -12 %) than IMC algorithm especially over orographic areas. In extremely heavy rainfall cases both the algorithms behave in the same manner and captures the events although it is differing magnitude wise. Seasonal analysis of monsoon 2021 rainfall shows that 8 subdivisions have negative biases in the range of 50-60 mm) and 24 subdivisions have negative biases in the range of 0-20 mm, except Konkan Goa, Coastal Karnataka & A & N Islands have positive biases. Therefore, there is need to strengthen the actual observation rainfall measuring network and re-examine the performance of algorithms with larger data sets so that current algorithms retuned as per changing scenario.
Forensic odontology has recently become an integral part of forensic science. Since, 100 years this science has been utilizing dental or oro-facial findings to aid in serving the judicial system. Dental identification holds an important role in the identification of remains after postmortem changes, traumatic tissue injury or lack of a fingerprint record. Forensic identification based on assessment of prosthodontic appliances and or prosthesis by methods such as of labeling of dentures and other prosthetic appliances could provide vital clues for victim identification. Other sources such as salivary sample collection from the prosthesis can provide a rich source of DNA collection. How, a prosthodontist can play a crucial role in forensic medicine by application of various modes that can aid in identification of a deceased individual is illustrated in this review article.

Boron nitride cloth was tested to determine its suitability for use as a separator in lithium/iron-sulfide cells. The cloth was purified and placed between the electrodes of cells using an LiCl-KCl electrolyte. Charge and discharge cycles were performed at a temperature of 700-750 K. In a cell with two liquid-lithium electrodes at 690 K for 10.8 Ms, the cloth suffered only slight corrosion; in a cell with lithium-aluminum and iron-sulfide electrodes at 750 K for 37.5 Ms and in a cell with two lithium-silicon electrodes of maximum composition of Li/sub 15/Si/sub 4/ at 750 K for 10.8 Ms, no deterioration was observed in static-immersion tests of purified boron nitride cloth and solid pieces in an Li-LiCl-KCl melt inside a sealed stainless-steel capsule at 675 K for 10.8 Ms.
Abstract Climate change increasingly affects agriculture, global biodiversity, and species dispersal, necessitating adaptive strategies for sustainable agricultural practices. In Himachal Pradesh, the agricultural sector is embracing diversification, focusing on producing off-season vegetables such as tomato, capsicum, broccoli, potato, ginger, soybean, oilseeds, and pulses. This shift towards cash crops enhances farmer income and aligns with the region's agro-climatic conditions, promoting economic sustainability. This study investigates the sustainable potential of formulations derived from various weed plants (Parthenium hysterophorus, Lantana camara, Artemisia roxburghiana) as biocontrol agents against fungal infections caused by Alternaria alternata in cash crops. Employing GCMS analysis, we identified key bioactive compounds: Beta-Caryophyllene (C15H24) in L. camara, 2-Chloroethyl linoleate (C20H35ClO2) in P. hysterophorus, and 2-(1,2,2-trimethylcyclopenten-3-en-1-yl) acetaldehyde (C10H16O) in A. roxburghiana. These compounds represent a sustainable alternative to synthetic fungicides, aligning with integrated pest management practices that reduce chemical inputs and enhance ecological balance. Molecular docking studies were conducted to evaluate the binding interactions between these bioactive compounds and the Alternaria alternata allergen protein Alt a1, compared to the antifungal drug Fluconazole. Notably, the ligand Tricyclo [4.4.0.01,5] deca-3,5,7,9-tetraene from L. camara exhibited the highest binding affinity (-3.98 Kcal/mol), suggesting its potential as a viable biopesticide. Key residues involved in protein-ligand interactions—VAL32, LYS63, LYS41, and TYR147—were identified as critical targets for mitigating A. alternata infections. This research underscores the significance of utilizing natural plant-derived compounds in sustainable agriculture, contributing to the resilience of cash crops while fostering biodiversity conservation. By integrating such biocontrol strategies, we can enhance food security and promote sustainable farming practices in the face of climate change.
