Unsoundness of Aggregate due to Volume Change01:26

Unsoundness of Aggregate due to Volume Change

489
Unsoundness in aggregates due to volume changes is primarily caused by the physical alterations aggregates undergo, such as freezing and thawing, thermal changes, and wetting and drying. Unsound aggregates, when subjected to these changes, result in volume change upon disintegration. This, in turn, contributes to the deterioration of concrete, including scaling, pop-outs, and cracking. Particular types of aggregates, such as porous flints, cherts, and those containing clay minerals, are...

Responses to Salt Stress

15.1K
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

The Colloidal State01:29

The Colloidal State

155
The formation of a colloidal system is exemplified by an aqueous solution containing Cl− ions is introduced to another containing Ag+ ions, resulting in the precipitation of solid AgCl as extremely tiny crystals. Instead of settling out as a filterable precipitate, these crystals remain suspended in the liquid, showcasing a colloidal system.A colloidal system involves colloidal particles within the approximate range of 1 to 1000 nm in at least one dimension, dispersed in a medium called...

Limits with Oscillating Discontinuities

627
An oscillating discontinuity is a type of discontinuity in which a function’s values fluctuate infinitely often as the input approaches a particular point. Unlike jump discontinuities, where the function suddenly shifts between two values, or infinite discontinuities, where the function diverges without bound, an oscillating discontinuity arises from rapid back-and-forth variation. Because the function never stabilizes toward a single value, no finite limit exists at that point.One of the...

Ecological Succession02:17

Ecological Succession

22.2K
Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...

Atomic Emission Spectroscopy: Overview01:20

Atomic Emission Spectroscopy: Overview

4.4K
Atomic emission spectroscopy (AES) is an analytical technique used to determine the elemental composition of a sample by analyzing the light emitted from excited atoms. In AES, atoms in a sample are excited to higher energy levels by thermal energy from high-temperature sources, such as plasma, arcs, or sparks. When these excited atoms return to lower energy states, they emit light at specific wavelengths characteristic of each element. The resulting atomic emission spectrum, which consists of...

Area of Science:

  • Earth and Environmental Sciences
  • Geophysics
  • Fluid Dynamics

Background:

  • Aeolian sediment transport is crucial for arid landscapes.
  • Understanding the initiation of particle motion (saltation) is key.
  • Turbulent wind fluctuations significantly influence particle entrainment.

Purpose of the Study:

  • Investigate the dynamics of Aeolian particle transport near the saltation threshold.
  • Characterize the discontinuous flux regime and its associated scaling laws.
  • Explore the role of wind entrainment and feeding in sustaining saltation.

Main Methods:

  • Wind tunnel experiments were conducted to observe particle transport.
  • Measurements of wind fluctuations and time delays between particle bursts were recorded.
  • A numerical model simulating saltation, including wind entrainment, was developed and validated.

Main Results:

  • A regime of discontinuous particle flux, characterized by bursts, was identified near the saltation onset.
  • Scaling laws were observed for the time delay between bursts and wind fluctuations at the fluid threshold (Shields number θc).
  • The numerical model successfully reproduced the experimental observations, providing insights into the underlying mechanisms.

Conclusions:

  • Discontinuous flux and burst dynamics are inherent to Aeolian saltation near the threshold.
  • Wind entrainment driven by turbulent fluctuations plays a critical role in initiating and sustaining saltation.
  • Sustaining discontinuous flux below the fluid threshold is achievable through particle feeding.
