Plasticity00:58

Plasticity

3.1K
Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...

Plasticizers01:31

Plasticizers

367
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

1.6K
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Plastic Behavior01:21

Plastic Behavior

573
A material's elastic behavior is characterized by the disappearance of stress once the load is removed, allowing the material to return to its original state. However, when stress surpasses the yield point, yielding commences, marking the onset of plastic deformation or permanent set. This change from elastic to plastic behavior is influenced by the peak stress value and the duration before the load is removed. An intriguing observation occurs when a specimen is loaded, unloaded, and...

Plastic Deformations01:14

Plastic Deformations

438
It is essential to understand how structural members behave under plastic deformation when the bending stress exceeds the material's yield strength. This state of deformation permanently alters the shape of the member, in contrast to the linear elastic behavior observed before yielding. The strain at any point in the member is expressed in terms of maximum strain. Notably, the neutral axis, which coincides with the centroid during elastic bending, shifts away from the centroid under plastic...

Area of Science:

  • Environmental Science
  • Ecotoxicology
  • Pollution Studies

Background:

  • Plastic pollution is globally distributed, yet its presence and impact in terrestrial and freshwater ecosystems are less understood than in marine environments.
  • Hydrological catchments offer a defined scale for investigating and managing plastic pollution, connecting various ecosystems.
  • Rivers are identified as pollution hotspots and crucial pathways for plastic transport between terrestrial, freshwater, and marine systems.

Purpose of the Study:

  • To review the transport and ecological effects of plastics across terrestrial, freshwater, and marine environments.
  • To highlight the importance of hydrological catchments as an integrated scale for plastic pollution research and management.
  • To identify knowledge gaps and call for comprehensive research to inform effective plastic pollution management and risk assessment.

Main Methods:

  • Literature review synthesizing current understanding of plastic transport and effects.
  • Focus on hydrological catchments as units for analysis.
  • Identification of key research needs in quantification, dose-response relationships, scaling, and biomonitoring.

Main Results:

  • Plastic pollution is ubiquitous, with rivers acting as significant conduits and hotspots.
  • Understanding of plastic sources, fluxes, and sinks within catchments is limited.
  • Ecological effects of micro- and nanoplastics are poorly understood, especially at population and ecosystem levels.

Conclusions:

  • More research is urgently needed to quantify plastic pollution dynamics in catchments and transitional waters.
  • Developing environmentally relevant dose-response relationships and scaling up from individual to ecosystem-level impacts are critical.
  • Improved biomonitoring using ecologically relevant metrics is essential for effective plastic pollution management and risk assessment.
