متن کاملStone circles: form and soil kinematics.
Distinct surface patterns are ubiquitous and diverse in soils of polar and alpine regions, where the ground temperature oscillates about 0 degrees C. They constitute some of the most striking examples of clearly visible, abiotic self-organization in nature. This paper outlines the interplay of frost-related physical processes that produce these patterns spontaneously and presents unique data do...
متن کاملEvaluation of freezing tolerance in olive cultivars by stomatal density and freezing stress
Selection of frost tolerant cultivars and understanding the mechanisms of frost hardiness could help to improve freezing resistance in olive plants. Olive cultivars may differ in frost hardiness due to differential survival of specific organs. The aim of this study was to screen different olive cultivars based on their stomatal density and metabolic modifications under cold conditions. The ‘Zar...
متن کاملStepping-stone model with circular Brownian migration
In this paper we consider a stepping-stone model on a circle with circular Brownian migration. We first point out a connection between Arratia flow and the marginal distribution of this model. We then give a new representation for the stepping-stone model using Arratia flow and circular coalescing Brownian motion. Such a representation enables us to carry out some explicit computation. In parti...
متن کاملNovel use of a ureteroscopic stone entrapment device to prevent antegrade stone migration during percutaneous nephrolithotomy.
The Accordion stone management device is a hydrophilic microcatheter-based tool that blocks stone migration. This instrument has been described for use during ureteroscopy to prevent retropulsion of stone fragments. We used this device during percutaneous nephrolithotomy (PCNL) in 30 patients to prevent antegrade migration of stone fragments (group 1), and find that the device is easily inserte...
