We present a new calculation of Australia’s ecological footprint. Modifications have been made to the concept as originally proposed, in response to its perceived shortcomings: rather than characterising the consumption of the Australian population in terms of appropriated ‘bioproduction’ at world-average productivity, a regional, disturbance-based approach is taken, including actual Australian...

This paper assesses the progress made over the last decade in validating footprint models, and highlights shortcomings which need addressing. This paper also presents alternative methods of validating footprint models. The vigorous expansion of footprint models was spurred by the development and subsequent widespread application of primarily analytical solutions to the advection–diffusion equat...

The aim of this study is to estimate the green, blue and grey water footprint of wheat in a spatially-explicit way, both from a production and consumption perspective. The assessment is global and improves upon earlier research by taking a high-resolution approach, estimating the water footprint of the crop at a 5 by 5 arc minute grid. We have used a grid-based dynamic water balance model to ca...

BACKGROUND It is common to place the posterior cruciate ligament (PCL) tibial tunnel with a transtibial technique using a guide that attempts to place the center of the tunnel 1 to 1.5 cm distal to the tibiofemoral joint. It is unknown how well this technique will re-create the native tibial footprint of the PCL. PURPOSE To evaluate the accuracy of tibial tunnel placement using a transtibial ...

PURPOSE Arthroscopic repair of the subscapularis tendon has become more prevalent in recent years. Tears of the subscapularis insertion can be measured arthroscopically when the size of the average subscapularis tendon insertion is known. This anatomic study was performed to measure the dimensions and describe the anatomy of the subscapularis footprint. METHODS A total of 6 male and 6 female ...

This study has investigated how average effective leaf area index (LAIe) derived from full-waveform and discrete LiDAR data changes depending on the size of the grid used, over a 150 m by 80 m area of orange orchard. The full-waveform data, acquired with RIEGL LMS-Q560, were decomposed and optimized with a trust-region-reflective algorithm using a custom decomposition procedure focused on extra...

In non-cooperative bistatic synthetic aperture radar (SAR), the position of transmitter’s beam footprint should be detected and tracked in real-time to perform beam synchronization. Theoretical analysis shows that signal-tonoise ratio (SNR) of the reflected echoes from the observational scene is too low to apply the conventional detection and tracking method. According to the cross-correlation ...

BACKGROUND Debate exists on the proper relation of the anterior cruciate ligament (ACL) footprint with the intercondylar notch in anatomic ACL reconstructions. Patient-specific graft placement based on the inclination of the intercondylar roof has been proposed. The relationship between the intercondylar roof and native ACL footprint on the tibia has not previously been quantified. HYPOTHESIS...
