In the present study, effects of zinc oxide nanoparticles (ZnO NPs) on rice (Oryza sativa L. cv. PB1509) plant growth were assessed in hydroponics (5, 10, 25, 50 mg L−1) and soil microcosm 25 kg−1) experiments. both experiments, Zinc (Zn) accumulation parts (roots, shoots grains) was found to increase with increasing doses ZnO NPs. Grains accumulated 29 kg−1 Zn at NPs experiment. experiment, ph...
This review deals with computer simulation of biological aging, particularly with the Penna model of 1995. They are based on the mutation accumulation theory of half a century ago. The results agree well with demographical reality, and also with the seemingly contradictory influence of predators on the aging of prey.
Accumulation of contextual data offers new opportunities to improve the preventative health and wellbeing interventions. In this paper, we discuss the importance of understanding the context elements of Behavior Change Support Systems (BCSSs) and present an Event model illustrating the Use, User and Technology Context factors of the Persuasion Context. The model is a conceptual tool for identif...
BACKGROUND Boron neutron capture therapy (BNCT) is a molecular radiation treatment based on the (10)B (n, α) (7)Li nuclear reaction in cancer cells, in which delivery of (10)B by 4-borono-phenylalanine conjugated with fructose (BPA-fr) to the cancer cells is of critical importance. The PET tracer 4-borono-2-(18) F-fluoro-phenylalanine (FBPA) has been used to predict the accumulation of BPA-fr b...
Viral transmission pathways have profound implications for public safety; it is thus imperative to establish a complete understanding of viable infectious avenues. Mounting evidence suggests SARS-CoV-2 can be transmitted via the air; however, this has not yet been demonstrated. Here we quantitatively analyze virion accumulation by accounting aerosolized emission and destabilization. Reported su...
