Abstract
Ochnaflavone is a naturally occurring biflavonoid mainly isolated from Ochna integerrima, manifests health benefits encompassing antidiabetic, anticancer, anti-cardiovascular, and anti-inflammatory activities. However, most bioactivity research has focused on in vitro experiments, rather than in vivo disease models, toxicological assessments, and human clinical trials. Moreover, a comprehensive review of the pharmacological aspects of ochnaflavone is conspicuously lacking. Thus, this review provides a concise and comprehensive summary of existing knowledge on the chemical structure, plant origin, physical properties, biotransformations, and multifaceted biological activities of ochnaflavone along with an in-depth exploration of the complex molecular mechanisms behind these activities, including signaling pathways and gene expression regulation, with the aim of promoting future theoretical needs for ochnaflavone in clinical trials and providing comprehensive insights into the research and application of this valuable natural compound.

The use of bio-based composites to enhance the methane production in anaerobic digestion has attracted considerable attention. Nevertheless, the study of electron transfer mechanisms and the applications of biochar/MnO2 (MBC) in complex systems remains largely unexplored. Biochar composited with MnO2 at 10:1 mass ratio (MBC10) increased the content of volatile fatty acids by 9.09 % during acidogenic phase. During the methanogenic experiments using acetate, cumulative methane production (CMP) rose by 5.83 %, and in the methanogenic experiments using food waste, CMP increased by 24.32 %. Microbial community analysis indicated an enrichment of Syntrophomonas, Bacilli, and Methanosaetaceae in the MBC10 group. This enrichment occurred mainly due to the redox capability of MnO2 enhancing MBC capacitance, thereby facilitating microbial electron transfer processes. Additionally, under 2 g/L ammonia nitrogen concentration and 30 g/L organic load, the CMP of MBC10 increased by 12.74 % and 9.44 %, respectively, compared to the BC600 group. This study illuminates MBC's electron transfer mechanisms and applications, facilitating its wider practical adoption and fostering future innovations.

Abstract
This report describes the development of models to calculate losses of soil particles, phosphorus, nitrogen and organic carbon from agricultural land to first order streams. The results from the models serve as input data to the TEOTIL model which estimates the net losses from agriculture and all other sources. The agricultural models (AGRITIL) were calibrated for catchments in the Agricultural Environmental monitoring programme and are limited by the availability of data for different regions in Norway.
Abstract
The introduction of unmanned aerial vehicles (UAV), or drones, to traditional reindeer herding has – literally – given indigenous Sámi herders a new perspective: the aerial one.
