Le Chatelier's Principle: Changing Concentration02:27

Le Chatelier's Principle: Changing Concentration

66.1K
A system at equilibrium is in a state of dynamic balance, with forward and reverse reactions taking place at equal rates. If an equilibrium system is subjected to a change in conditions that affects these reaction rates differently (a stress), then the rates are no longer equal and the system is not at equilibrium. The system will subsequently experience a net reaction in the direction of a greater rate (a shift) that will re-establish the equilibrium. This phenomenon is summarized by Le...

Le Chatelier's Principle: Changing Temperature

35.6K
Consistent with the law of mass action, an equilibrium stressed by a change in concentration will shift to re-establish equilibrium without any change in the value of the equilibrium constant, K. When an equilibrium shifts in response to a temperature change, however, it is re-established with a different relative composition that exhibits a different value for the equilibrium constant.
To understand this phenomenon, consider the elementary reaction:

For gas-phase equilibria, changes in the concentrations of reactants and products can occur with altered volume and pressure. The partial pressure, P, of an ideal gas is proportional to its molar concentration, M.

A standard box and whisker plot informs us about the spread of the data in a given sample. One can identify the minimum value, maximum value, first quartile value, second quartile or median value, and third quartile.
However, the box plot does not tell the reader about outliers - values that lie far from the center of the data. We can modify the standard box and whisker plot to identify the outliers and visualize the actual spread of the data in a sample.
Initially, we calculate the adjusted...

Logarithmic and piecewise functions play central roles in mathematical modeling, particularly when capturing nonlinear or segmented behaviors in real-world phenomena. Although these functions differ fundamentally in structure and application, both serve to represent complex relationships in simplified mathematical terms.A logarithmic function is defined as the inverse of an exponential function, expressed as These functions grow quickly for small values of x but slow down as x increases,...

Area of Science:

  • Craniofacial surgery
  • Orthognathic surgery
  • Plastic surgery

Background:

  • Midface hypoplasia presents complex aesthetic and functional challenges.
  • Traditional Le Fort III osteotomy techniques may have limitations in addressing specific deformities.

Purpose of the Study:

  • To present three novel variations of the modified Le Fort III osteotomy (MLFIIIO).
  • To offer tailored surgical solutions for diverse midface deformities.

Main Methods:

  • Development of three distinct MLFIIIO techniques: modified Champy, Z-osteotomy, and ascending osteotomy.
  • Techniques are designed based on individual patient requirements and deformity characteristics.
  • Utilizes surgical guides and specific approaches (subciliary or transconjunctival).

Main Results:

  • Successful horizontal advancement up to 6 mm without grafts (modified Champy).
  • Correction of larger horizontal discrepancies (>6 mm) without bone grafting (Z-osteotomy).
  • Addressing orbital dystopia with the ascending technique, sometimes combined with other procedures.

Conclusions:

  • The presented MLFIIIO variations provide excellent outcomes for midface advancement.
  • These techniques allow for precise customization to individual patient needs.
  • The methods ensure proper projection of the midface and protection of the eyeball.
