Pore Size Distribution01:23

Pore Size Distribution

492
In concrete, the pore size distribution significantly influences the material's properties. Capillary pores, markedly larger than gel pores, form a vast network within partially hydrated cement paste, reducing the concrete's strength and increasing its permeability. This heightened permeability leads to a greater risk of damage from environmental factors like freeze-thaw cycles and chemical attacks, with the extent of vulnerability also being tied to the water-to-cement ratio.

Pore Transport and Ion-Pair Transport01:17

Pore Transport and Ion-Pair Transport

1.3K
Pore transport and ion-pair formation are critical mechanisms for the absorption and distribution of drugs in the body.
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited  but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct...

Measures of Central Tendency02:16

Measures of Central Tendency

21.5K
The "center" of a data set is also a way of describing location. The two most widely used measures of the "center" of the data are the mean (average) and the median. The words "mean" and "average" are often used interchangeably. The substitution of one word for the other is common practice. The technical term is "arithmetic mean" and "average" is technically a center location. However, in practice among non-statisticians,...

Measurement: Standard Units03:38

Measurement: Standard Units

81.7K
Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

Measuring Reaction Rates

31.0K
Polarimetry finds application in chemical kinetics to measure the concentration and reaction kinetics of optically active substances during a chemical reaction. Optically active substances have the capability of rotating the plane of polarization of linearly polarized light passing through them—a feature called optical rotation. Optical activity is attributed to the molecular structure of substances. Normal monochromatic light is unpolarized and possesses oscillations of the electrical...

Uncertainty in Measurement: Significant Figures03:34

Uncertainty in Measurement: Significant Figures

83.7K
All the digits in a measurement, including the uncertain last digit, are called significant figures or significant digits. Note that zero may be a measured value; for example, if a scale that shows weight to the nearest pound reads “140,” then the 1 (hundreds), 4 (tens), and 0 (ones) are all significant (measured) values.

Area of Science:

  • Dermatology
  • Cosmetic Science
  • Imaging Technology

Background:

  • Enlarged pores are a common cosmetic concern for women.
  • Subjective assessments lack quantification; bioengineered methods are needed.
  • The Antera 3D device offers potential for objective pore measurement.

Purpose of the Study:

  • To evaluate the suitability of the Antera 3D for pore measurements.
  • To assess the repeatability of Antera 3D parameters.
  • To determine the efficacy of a pore minimizer product using the Antera 3D.

Main Methods:

  • Pore measurements were taken on 22 women (18-65 years) using Antera 3D, DermaTOP, and photographic analysis.
  • Four raters graded pore size from photographs (0-5 scale).
  • Repeatability and product efficacy (pore minimizer) were assessed.

Main Results:

  • Antera 3D pore parameters correlated with rater assessments, excluding Max Depth.
  • Mean pore volume, area, and count showed moderate correlation with DermaTOP.
  • Antera 3D did not correlate with photographic pore visibility analysis.
  • Mean pore volume, area, and max depth were most repeatable, particularly with small/medium filters.
  • Pore minimizer efficacy was most evident for mean pore volume and area using the small filter.

Conclusions:

  • Antera 3D is a reliable tool for efficacy and field studies on pore size.
  • Small filter analysis is recommended for mean pore volume and area measurements.
  • Objective pore quantification complements subjective assessments.
