چکیده
Abstract The main objective of this study was to explore the height–diameter relationship plantation-grown juvenile black locust trees and clarify if tree height can be adequately predicted at stand level from breast-height diameter which is most appropriate functional form; predictions expanded a wider region by mixed-effects modelling relevant for model localisation; random parameter components calibrated with stand-level variables them an predictor. We first fitted seven one-predictor models plot we selected adequate simple function according set goodness-of-fit criteria. It then approximated over entire data in nine different forms that were compared Likelihood Ratio Test. Calibrations component best measurement one each occasion plantation-level variable attempted. Our derived two-predictor deterministic models, based on exponential reciprocal value diameter, constant intercept 1.3. Height–diameter localisation level, regardless geographic region, suitable investigated data. specific rate form differentiated plantations their growth potential. A positive correlation between increase growing space also distinguished allowed calibration linear spacing develop function. However, showed higher predictive power than purely relationship.

Which is which and who is who: Roger Waters up against Media
Pink Floyd was a British band whose work began in the late 60s. Roger Waters, the main contributor of the band, wrote almost all the lyrics and was also a main figure behind producing the motion picture of the album. He deliberately attacks Western media in both the lyrics he has written for the band and his solo projects. The present study finds this tendency of assaulting the media deeply roo...
