Quanti®cation of nitrogen assimilation ef®ciencies and their use to estimate organic matter consumption by the earthworms Aporrectodea tuberculata (Eisen) and Lumbricus terrestris L
Earthworms affect nitrogen cycling directly through the consumption and assimilation of organic N and the turnover of N through excretion and mortality. Although earthworms can process large quantities of organic matter, organic-matter consumption by earthworms based on their nitrogen requirements has not been quanti®ed. Organic-matter consumption and the ef®ciency of nitrogen assimilation by e...
متن کاملFast volume scanning approaches by X-ray-computed tomography
X-ray-computed tomography (CT) successfully underwent a transition from slice-by-slice imaging to volume imaging in the decade after 1990 due to the introduction of spiral scan modes. Later, the transition from single-slice to multislice scanning followed. With the advent of new detector technologies we are now looking forward to circular and spiral scanning using area detectors and the respect...
متن کاملImpact of Photon Spectra on the Sensitivity of Polymer Gel Dosimetry by X-Ray Computed Tomography
Introduction: The purpose of the current study was to investigate the effect of X-ray spectra on the sensitivity of a polymer gel dosimeter imaged with a conventional computed tomography (CT) scanner. Material and Methods: The whole process of CT imaging of an irradiated polymer gel was simulated by MCNPX Monte Carlo (MC) code. The imaging of polyacrylamide gel was accomplished by means of a co...
متن کاملX-ray computed tomography.
X-ray computed tomography (CT), introduced into clinical practice in 1972, was the first of the modern slice-imaging modalities. To reconstruct images mathematically from measured data and to display and to archive them in digital form was a novelty then and is commonplace today. CT has shown a steady upward trend with respect to technology, performance and clinical use independent of predictio...
