A combination cyanobacterial treatment approach using hydrogen peroxide and L-lysine successfully improved the removal efficiency of toxic cyanobacteria.

Harmful cyanobacterial blooms have been increasing globally, introducing new challenges for protecting aquatic ecosystems and human health. A combined algaecide treatment, similar to combination antibiotic therapy, may more rapidly and effectively remove cyanobacteria by broad targeting of different growth mechanisms, reducing the recovery of bloom-forming cyanobacteria. To confirm this hypothesis, hydrogen peroxide (10.

Influence of flexible multibeam intensity distributions on selective laser-induced etching process regimes.

The precision and versatility of selective laser-induced etching in fused silica render it indispensable for many applications in medical engineering, the semiconductor industry, and quantum technology. However, its process-limited productivity renders it unsuitable for a wider set of applications, particularly those that require cost-effective solutions. As the process is largely concerned with microprocessing applications, a promising method to enhance process efficiency is through parallelization using multiple beams with high packing density.

Pollen products collected from honey bee hives experiencing minor stress have altered fungal communities and reduced antimicrobial properties.

Fungi are increasingly recognized to play diverse roles within honey bee hives, acting as pathogens, mutualists, and commensals. Pollen products, essential for hive nutrition, host significant fungal communities with potential protective and nutritional benefits. In this study, we profile the fungal communities and antifungal properties of three pollen products from healthy and stressed hives: fresh pollen collected by forager bees from local plants; stored pollen packed into the comb inside the hive; and bee bread, which is stored pollen following anaerobic fermentation used for bee and larval nutrition.

Attributes of leadership skill development in high-performance pre-hospital medical teams: results of an international multi-service prospective study.

Backgrounds: Team leadership skills of physicians working in high-performing medical teams are directly related to outcome. It is currently unclear how these skills can best be developed. Therefore, in this multi-national cross-sectional prospective study, we explored the development of these skills in relation to physician-, organization- and training characteristics of Helicopter Emergency Medicine Service (HEMS) physicians from services in Europe, the United States of America and Australia.

Nurse bees regulate the larval nutrition of developing workers (Apis mellifera) when feeding on various pollen types.

Nutrition has been identified as a key driver of colony health and productivity. Yet, in honey bees, relatively little is known about how the vast variety of natural pollen sources impact larval development. The impact of the nutritional quality of 4 naturally occurring pollen sources, of importance to the Western Australian beekeeping industry, was tested on honey bee (Apis mellifera L.
