Root phosphatase activity is a competitive trait affiliated with the conservation gradient in root economic space

open access: goldForest Ecosystems, 2023
Background: The diversity of resource acquisition strategies of plant roots determines the species coexistence patterns to a certain extent. However, few root physiological traits have been investigated, such as root phosphatase activity (PA) that ...

Effect of Immediate and Delayed Post Space Preparation on Apical Leakage Using Three Root Canal Obturation Techniques After Rotary Instrumentation

open access: greenJournal of the Formosan Medical Association, 2011
For teeth that have undergone root canal therapy post fabrication and subsequent crown restoration are often required to increase strength. It is necessary to remove a portion of gutta-percha during post space preparation that may cause displacement of ...

On split twisted inner derivation triple systems with no restrictions on their 0-root spaces

open access: yesOpen Mathematics, 2022
The aim of this paper is to study the structure of arbitrary split twisted inner derivation triple systems. We obtain a sufficient condition for the decomposition of arbitrary twisted inner derivation triple system T{\mathscr{T}} which is of the form T=U+
