Synthesis, characterization, and process optimization of natural coagulants from jackfruit and durian seeds for turbidity removalNARA Subscribed
Starch was extracted from jackfruit and durian seeds using distilled water and alkaline methods, with higher yields obtained via distilled water (27.7% and 18.4%, respectively). The extracted starches were cationized using 3-chloro-2-hydroxypropyltrimethylammonium chloride (CTA) to enhance coagulation performance. Characterization confirmed successful functionalization, with particle size increases of 32% (jackfruit) and 45% (...
Warming Reduces the Positive Effect of Nitrogen Addition on Soil Organic Carbon in GrasslandsNARA Subscribed
Nitrogen (N) addition can increase soil organic carbon (SOC) in some grasslands, however, it is unknown whether N addition may enhance SOC in a warmer climate at broad spatial scales. We conduct a field experiment to test how N addition and warming interactively influence SOC in a temperate semiarid grassland. N addition significantly increases SOC by 14%, while simultaneous N addition and warming significantly decreases SOC b...
Divergent sensory transcriptomic profiles in positive and negative learning in Bicyclus Anynana butterfliesNARA Subscribed
Mate preference learning, where individuals learn to prefer or avoid specific phenotypes during mate selection, is pervasive across animal taxa and influences reproductive isolation and trait evolution. Despite its significance, the genetic basis underlying the associated valence attribution (whether to prefer or avoid) remains largely unclear. Both in terms of what genes are associated with attributing valence, and whether va...
The biomedical engineer’s pledge: overview and contextNARA Subscribed
Although biomedical engineering (BME) is a profession with ethical responsibilities comparable to those in medicine, it has, until now, lacked a counterpart to the Hippocratic Oath. While professional societies have established codes of ethics for biomedical engineers, these documents lack the symbolic and ceremonial significance of an oath or pledge. By contrast, the recitation of the Hippocratic Oath, or its modern version,...
A retrospective comparison of [18F]FDG radiation dose following a transition from conventional to long axial field of view PET/CTNARA Subscribed
Long axial field of view (LAFOV) PET/CT scanners (> 1 m axial FOV) provide an order of magnitude higher system sensitivity compared with conventional scanners. This creates opportunities for significant radiation dose reductions for patients, without loss of diagnostic image quality or increased scan time. This study aimed to investigate changes in radiation dose received by patients undergoing whole-body [ 18 F]FDG PET/CT stu...
Aim Plant invasions are a global problem that requires studying plants and their environmental associations across native and introduced ranges. Location 2000 km transects in China, Europe and North America. Time Period June 2019–July 2020. Major Taxa Studied Japanese knotweed ( Reynoutria japonica ). Methods We surveyed 150 populations of Japanese knotweed, a noxious invader of the temperate zone, along 2000 km transects in n...
Biogeography of a Global Plant Invader: From the Evolutionary History to Future DistributionsNARA Subscribed
Biological invasions pose a global challenge, affecting ecosystems worldwide and human societies. Knowledge of the evolutionary history of invasive species is critical to understanding their current invasion success and projecting their future spread. However, to date, few studies have addressed the evolutionary history and potential future spread of invaders simultaneously. In this study, we explored both evolutionary history...
Geographic variation in leaf traits and palatability of a native plant invader during domestic expansionNARA Subscribed
Like alien plant invasion, range expansion of native plants may threaten biodiversity and economies, rendering them native invaders. Variation in abiotic and biotic conditions across a large geographic scale greatly affects variation in traits and interactions with herbivores of native plant invaders, which is an interesting yet mostly unexplored issue. We used a common garden experiment to compare defensive/nutritional traits...
