ELASTIC WAVES IN FRACTURED ROCKS UNDER PERIODIC COMPRESSION

Elastic waves in fractured rocks under periodic compression

Abstract Background One of the current problems in studying the mechanical properties and behavior of structurally inhomogeneous media IRON CHELATE 25 MG with cracks is the characterization of acoustic wave propagation.This is especially important in Geomechanics and prognosis of earthquakes.Methods In this work, the authors propose an approach tha

Guide to serial synchrotron crystallography

Serial crystallography (SX) is an emerging technique that can be used to determine the noncryogenic crystal structure of macromolecules while minimizing radiation damage.Applying SX using pump-probe Measuring Spoon Set or mix-and-inject techniques enables the observation of time-resolved molecular reactions and dynamics in macromolecules.After the

Evaluation of a Rapid Point of Care Test for Detecting Acute and Established HIV Infection, and Examining the Role of Study Quality on Diagnostic Accuracy: A Bayesian Meta-Analysis.

INTRODUCTION:Fourth generation (Ag/Ab combination) point of care HIV tests like the FDA-approved Determine HIV1/2 Ag/Ab Combo test offer the promise of timely detection of acute HIV infection, relevant in the context of HIV control.However, a synthesis of their performance has not yet been done.In this meta-analysis we not only assessed device perf

Forest matters: Use of water reservoirs by mammal communities in cattle ranch landscapes in the Paraguayan Dry Chaco

Cattle ranching has led to a significant decrease in forest cover in the Neotropic.In this study we evaluate how medium- and large-sized mammals Mounting Bracket cope in these human-modified landscapes in the Paraguayan Dry Chaco, where by state law at least 25% of forest cover must be preserved.Using a camera-trap approach, we studied how the surr
