Line Loss01:10

Line Loss

543
The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.
Line loss impacts power delivery efficiency in a balanced three-phase circuit. The symmetry in such a circuit simplifies the...

Weighted Mean00:57

Weighted Mean

6.3K
While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

Reducing Line Loss01:18

Reducing Line Loss

390
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...

Atomic Weight01:25

Atomic Weight

13.0K
Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams. Scientists arbitrarily define this amount of mass as one atomic mass unit (amu) or one Dalton. Electrons are much smaller in mass than protons, weighing only 9.11 × 10-28 grams, or about 1/1800 of an atomic mass unit. As a result, they do not contribute much to an element's overall atomic mass. This means that, when considering atomic mass, it is customary to ignore the mass of any electrons and...

Mass and Weight01:19

Mass and Weight

15.3K
Mass and weight are often used interchangeably in everyday conversation. For example,  medical records often show our weight in kilograms, but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of the Earth on an object. It depends on the distance from the center of the Earth. Weight dramatically varies if we leave the Earth's surface, unlike mass, which does not vary with location. On the Moon, for example, the...

Apparent Weight01:09

Apparent Weight

9.8K
True weight is the measure of the gravitational force acting on an object. However, if the object accelerates, its measured weight is different from its true weight. Similar observations can be made when the object is submerged in water. An object's weight in water is its apparent weight, which is equal to the difference between its true weight and the buoyant forces.
Consider a person standing on a bathroom scale inside an elevator. If the scale is accurate at rest, its reading equals the...

Area of Science:

  • Plastic Surgery
  • Reconstructive Surgery
  • Aesthetic Surgery

Background:

  • Patients experiencing massive weight loss often present with significant breast ptosis and tissue redundancy.
  • Traditional mastopexy techniques may not adequately address the unique challenges posed by post-bariatric or post-massive weight loss breast deformities.

Purpose of the Study:

  • To describe the technique of dermal suspension and parenchymal reshaping mastopexy for patients with massive weight loss.
  • To evaluate the efficacy, adaptability, and complication profile of this specific mastopexy approach.

Main Methods:

  • The study details a surgical technique involving dermal suspension and parenchymal reshaping tailored to individual breast deformities.
  • The procedure's ability to be combined with other common surgical operations is highlighted.

Main Results:

  • The dermal suspension, parenchymal reshaping mastopexy technique powerfully reshapes the breast.
  • The procedure is adaptable to individual patient deformities and can be safely combined with other surgeries.
  • The technique yields long-lasting results with a low incidence of minor, treatable complications.

Conclusions:

  • Dermal suspension, parenchymal reshaping mastopexy is a valuable and effective procedure for patients with massive weight loss.
  • The technique offers significant aesthetic improvement, adaptability, and a favorable safety profile.
  • This mastopexy approach provides durable outcomes with manageable complications suitable for an office setting.
