Electro-mechanical Systems

1.7K
Electromechanical systems are intricate configurations that effectively combine electrical and mechanical elements to achieve a desired outcome. Central to many of these systems is the DC motor, a device that converts electrical energy into mechanical motion, enabling various applications ranging from simple fans to complex robotic mechanisms.
A key component of the DC motor is the armature, a rotating circuit positioned within a magnetic field. As an electric current passes through the...

What is Energy?

59.8K
The universe is composed of matter in different forms, and all forms of matter contain energy.  The different forms of energy on Earth originate from the Sun — the ultimate energy source. Plants capture light energy from the Sun, and, via the process of photosynthesis, convert it into chemical energy. This stored energy from plants can be harnessed in many ways. For example, eating plant products as food provides energy for our body to function, and burning wood or coal (fossilized...

Free Energy01:21

Free Energy

52.3K
Free energy—abbreviated as G for the scientist Gibbs who discovered it—is a measurement of useful energy that can be extracted from a reaction to do work. It is the energy in a chemical reaction that is available after entropy is accounted for. Reactions that take in energy are considered endergonic and reactions that release energy are exergonic. Plants carry out endergonic reactions by taking in sunlight and carbon dioxide to produce glucose and oxygen. Animals, in turn, break...

Free Energy Changes for Nonstandard States

13.6K
The free energy change for a process taking place with reactants and products present under nonstandard conditions (pressures other than 1 bar; concentrations other than 1 M) is related to the standard free energy change according to this equation:

Potential Energy00:52

Potential Energy

43.0K
The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...

    Summary

    Low-energy laser, electroacupuncture, and neurostimulation devices show potential for healing musculoskeletal conditions like tendinitis and tennis elbow. However, their effectiveness is still debated among medical professionals.

    Area of Science:

    • Medical Devices
    • Physical Medicine
    • Regenerative Medicine

    Background:

    • Musculoskeletal conditions, including wounds, tendinitis, bursitis, and tennis elbow, represent a significant clinical challenge.
    • Traditional treatments for these conditions may not always provide adequate pain relief or promote optimal healing.
    • Emerging therapeutic modalities are being explored to address these limitations.

    Purpose of the Study:

    • To review the current applications of low-energy laser, electroacupuncture, and neuroprobe therapies.
    • To assess the potential of these modalities in promoting healing and reducing pain in musculoskeletal disorders.
    • To inform physicians about the emerging evidence and ongoing controversies surrounding these treatments.

    Main Methods:

    • Review of existing literature on low-energy laser therapy.
