A mobile laser-induced fluorescence spectrum (LIFS) lidar was developed for monitoring pollens floating in the atmosphere.The fluorescence spectrum of pollens excited at 355 nm was measured with a fluorescence spectrometer and the results suggested that in general they had peaks at around 460 nm and the ranges were 400–600 read more nm.A fluo
Introduction:.The orthopaedic surgery match has experienced a consistent increase in both the number of applicants and applications submitted per applicant.Preference signaling was implemented during the 2022 to 2023 application cycle in part to curtail the rising application burden on both applicants and residency programs.Our aim was to explore t
A noncircular face gear (NFG) conjugated with a pinion is a new type of face gear which can transmit variable velocity ratio and in which two time-varying excitations exist, namely the meshing stiffness excitation and instantaneous center excitation.Considering the tooth backlash, static transmission error and multifrequency parametric excitation,
Abstract Background Stem cells and stem cell lines are widely used in biomedical research.The Cell Ontology (CL) and Cell Line Ontology (CLO) are two community-based OBO Foundry ontologies in the domains of in vivo cells and in vitro cell line cells, respectively.Results To support standardized stem caruso milk thistle cell investigations, we have
Solitary bees are important but declining wild pollinators.During daily foraging in agricultural landscapes, they encounter a mosaic of patches with nest and foraging habitat and unsuitable matrix.It is insufficiently clear how spatial allocation of nesting and foraging resources and foraging traits of bees affect their daily foraging performance.W
