bioelectrical impedance analysis

Examples of bioelectrical impedance analysis in the following topics:

• Water Content in the Body

  • In bioelectrical impedance analysis, a person's hydration level is calculated from high precision measurements of the opposition to the flow of an electric current through body tissues.

• Impedance

  • The phase of the complex impedance is the phase shift by which the current is ahead of the voltage.
  • This quantity is known as the element's (complex) impedance.
  • The impedance of a resistor is R, while that of a capacitor (C) is $\frac{1}{j \omega C}$.
  • In the case of the circuit in , to find the complex impedance of the RC circuit, we add the impedance of the two components, just as with two resistors in series: $Z = R + \frac{ 1}{j \omega C}$.
  • The (real value) impedance is the real part of the complex impedance Z.

• Resistance and Resistivity

  • Resistance and resistivity describe the extent to which an object or material impedes the flow of electric current.
  • Resistance is the electric property that impedes a current.
  • These require a more sophisticated circuit analysis.

• Glomeromycota

  • The biochemical and genetic characterization of the Glomeromycota has been hindered by their biotrophic nature, which impedes laboratory culturing.
  • This analysis shows that all glomeromycetes probably descended from a common ancestor 462 and 353 million years ago, making them a monophyletic lineage.

• Management mistakes and the incompatibility of growth strategies and organizational structure

  • The only safeguard against this mistake is to conduct careful market and competitor analysis (See Chapter 13) to estimate the total market potential.
  • This analysis must be complemented by the choice of a strategy for capturing the market with which an assumed market potential can be developed, taking into account the given financial restrictions.
  • If team structures impede this because they are too slow, they must be replaced by hierarchical structures.

• Problem Solving

  • There are many common mental constructs that impede our ability to correctly solve problems in the most efficient manner possible.
  • Means-ends analysis: choosing an action at each step to move closer to the goal.
  • Morphological analysis: assessing the output and interactions of an entire system.

• Points of View: Micro-Meso-Macro

  • Poverty and thoughts related to poverty may take up so many cognitive resources for the poor that it actually impedes cognitive functioning, which accounts, in part, for the lower IQs measured among poor people.
