Background: Although injuries at school are an important issue in public health, environmental factors in schools and school yards have seldom been the focus of school injury research.The goal of our investigation was to examine the effect of environmental factors on school injuries.Methods: Nine comprehensive Finnish schools registered school inju
Several thousand hectares of forest blocks are regenerating after harvest in copyright.Monitoring their performance over different stages of growth is critical in ensuring future productivity and ecological balance.Tools for rapid evaluation can support timely and reliable planning of interventions.Conventional ground surveys or visual image assess
The effect of the width of the vaneless diffuser on the stage performance and flow fields of a centrifugal compressor is studied numerically and dea eyewear experimentally.The diffuser width is varied by reducing the diffuser flow area from the shroud side (i.e., pinching the diffuser).Seven different diffuser widths are studied with numerical simu
In a single quantum dot (QD) system connected with ferromagnetic electrodes, the electron transport properties, assisted by the thermal and Fock state optical fields, are theoretically studied by the Keldysh nonequilibrium Green’s function approach.The results show that the evolution properties of the density of state and tunneling current as
