BIOCRUSTS INTENSIFY WATER REDISTRIBUTION AND IMPROVE WATER AVAILABILITY TO DRYLAND VEGETATION: INSIGHTS FROM A SPATIALLY-EXPLICIT ECOHYDROLOGICAL MODEL

Biocrusts intensify water redistribution and improve water availability to dryland vegetation: insights from a spatially-explicit ecohydrological model

Biocrusts are ecosystem engineers in drylands and structure the landscape through their ecohydrological effects.They regulate soil infiltration and evaporation but also surface water redistribution, providing important resources for vascular vegetation.Spatially-explicit ecohydrological models are useful tools to explore such ecohydrological mechan

A general HIV incidence inference scheme based on likelihood of individual level data and a population renewal equation.

We derive a new method to estimate the age specific incidence of an infection with a differential mortality, using individual level infection status data from successive surveys.The method consists of a) an SI-type Table Top Accessories model to express the incidence rate in terms of the prevalence and its derivatives as well as the difference in m

Comparison of Microleakage of Mineral Trioxide Aggregate Apical Plug Applied by the Manual Technique and Indirect Use of Ultrasonic with Different Powers

Statement of the Problem: A mineral trioxide aggregate (MTA) apical plug is commonly applied prior to endodontic treatment of open-apex teeth.However, difficult application and condensation of MTA in the apical region is a drawback of this technique.Purpose: This study aimed to compare the microleakage of MTA apical plug applied by the manual techn
