Air-entraining Agents01:27

Air-entraining Agents

264
Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

Effects of Air-entrainment in Concrete

376
Air entrainment in concrete significantly enhances the material's durability, especially in environments subjected to freeze-thaw cycles. Introducing small air bubbles into the concrete mix acts as internal voids that accommodate the expansion of water when it freezes, thereby alleviating internal stress and preventing structural cracks. This function is crucial in climates with significant freezing and thawing, as it protects the concrete from repeated stresses that could lead to premature...

Measurement of Air Content in Concrete

616
Air content measurement in concrete is critical for ensuring structural integrity and durability of concrete structures, especially in environments prone to severe weather conditions. Accurate air content analysis optimizes concrete's resistance to freeze-thaw cycles and enhances its workability and strength. Several methods are standardized under ASTM guidelines to measure the air content in fresh concrete, each suitable for different concrete types and conditions.

The Soil Ecosystem02:23

The Soil Ecosystem

24.6K
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

Bioremediation00:46

Bioremediation

22.1K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Hybrid Zones02:29

Hybrid Zones

21.8K
Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.

Area of Science:

  • Environmental Medicine
  • Pulmonology
  • Epidemiology

Background:

  • Angioedema is a serious condition with multifactorial causes.
  • Identifying environmental triggers is crucial for patient management and prevention.
  • Previous research has not extensively explored the link between air quality and angioedema.

Purpose of the Study:

  • To investigate the association between environmental factors and angioedema.
  • To determine if air pollution levels correlate with angioedema episodes.

Main Methods:

  • A retrospective case series design was employed.
  • Chart review of 408 patients with 450 angioedema episodes from 2012-2014.
  • Environmental data (precipitation, humidity, air pollution) were statistically analyzed.

Main Results:

  • Unhealthy air pollution days were associated with higher angioedema presentation likelihood (OR 1.82).
  • Elevated ground-level ozone was the primary pollutant linked to angioedema (OR 4.95).
  • Ozone association was significant for angiotensin-converting enzyme inhibitor-related angioedema.

Conclusions:

  • Higher ground-level ozone levels significantly increase angioedema episode rates.
  • Air quality, specifically ozone, is an environmental factor precipitating angioedema.
  • This study is the first to demonstrate a link between air pollution and angioedema incidence.
