Insights

This study reveals specific distribution rules for channels and collaterals in the limbs and orifices. Understanding these patterns, known as distribution field rules, aids in syndrome differentiation and advancing traditional Chinese medicine theories.

Area of Science:

  • Traditional Chinese Medicine
  • Anatomy
  • Meridian Theory

Background:

  • The Yellow Emperor's Internal Classic and Classic on Medical Problem are foundational texts in Traditional Chinese Medicine.
  • Understanding the spatial relationships of channels and collaterals is crucial for effective treatment.
  • Previous studies have explored meridian pathways, but specific distribution rules require further elucidation.

Purpose of the Study:

  • To investigate the rules governing the distribution of channels and collaterals in their external connections with orifices and limbs.
  • To define the concept of the 'distribution field' for channels and collaterals.

Main Methods:

  • A summarization approach based on classical theories from The Yellow Emperor's Internal Classic and Classic on Medical Problem.
  • Analysis of classical texts to identify patterns in channel and collateral distribution.

Main Results:

  • Channels and collaterals exhibit a distinct steric-crossed distribution pattern on orifices and limbs.
  • This specific spatial arrangement is termed the 'rules of distribution field of channels and collaterals.'

Conclusions:

  • The identified rules of distribution field for channels and collaterals can guide treatment strategies based on syndrome differentiation.
  • This research contributes to the theoretical development and practical application of meridian and collateral studies in Traditional Chinese Medicine.

Distribution and Dispersion

Ecology is the study of how organisms interact with their environment and with one another. An important aspect of ecology is understanding where species are found and how individuals are distributed within those areas. The geographic range of a species refers to the total area where its members are located, while dispersion describes the pattern of spacing of individuals within that range.Geographic Range and Dispersion PatternsWithin a species’ geographic range, individuals may be distributed...
Extraction: Partition and Distribution Coefficients01:14

Extraction: Partition and Distribution Coefficients

The distribution law or Nernst's distribution law is the law that governs the distribution of a solute between two immiscible solvents. This law, also known as the partition law, states that if a solute is added to the mixture of two immiscible solvents at a constant temperature, the solute is distributed between the two solvents in such a way that the ratio of solute concentrations in the solvents remains constant at equilibrium.
For extracting a solute from an aqueous phase into an organic...
Kirchhoff's Rules01:21

Kirchhoff's Rules

Gustav Kirchhoff (1824–1887) devised two rules known as Kirchhoff's rules to analyze complex circuits, which cannot be analyzed with series-parallel techniques. These rules can be used to analyze any circuit, simple or complex.
Kirchhoff's first rule is called the junction rule. A junction, also known as a node, is a connection of three or more wires. The rule states that the sum of all currents entering a junction must equal the sum of all currents leaving the junction.
Kirchoff's Rules: Application01:22

Kirchoff's Rules: Application

Kirchhoff's rules quantify the current flowing through a circuit and the voltage variations around the loop in a circuit. Applying Kirchhoff's rules generates a set of linear equations that allow us to find the unknown values in circuits. These may be currents, voltages, or resistances.
When applying Kirchhoff's first rule, the junction rule, label the current in each branch and decide its direction. If the chosen direction is wrong, it will have the correct magnitude, although the current will...
Secondary Distribution01:25

Secondary Distribution

Secondary distribution systems provide electrical energy at the utilization voltage levels from distribution transformers to customer meters. Typical secondary voltages in the United States include 120/240 V for residential use, 208Y/120 V for residential and commercial use, and 480Y/277 V for industrial and high-rise commercial use.
In residential areas, 120/240 V single-phase, three-wire service is commonly used for lighting, outlets, and large appliances. Urban areas with high-density loads...

Design Example: Design of an Irrigation Channel

Trapezoidal channels are widely used in irrigation systems due to their cost-effectiveness and efficiency in conveying water. Trapezoidal channels feature a flat bottom and sloping sides, making them stable and easier to construct compared to other shapes. The bottom width and side slope ratio are determined based on the required flow capacity and site conditions. The side slope is kept gentle for unlined channels to prevent soil erosion.Hydraulic parameters in channel design include the flow...
