Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

496
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Membrane Asymmetry Regulating Transporters01:19

Membrane Asymmetry Regulating Transporters

7.2K
Enzymes like flippase, floppase, and scramblase transfer phospholipids from one layer to another in the membrane, thereby affecting membrane asymmetry.
Flippase
Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...

Increasing Function01:18

Increasing Function

401
An increasing function exhibits a rise in output values as input values increase. This behavior is depicted graphically as a curve or line that slopes upward from left to right. Such a function satisfies the condition that if x1 < x2, then f(x1) < f(x2), indicating that the function values grow with increasing inputs. This concept is fundamental in understanding growth trends across various domains, such as population dynamics, financial investments, or resource consumption.The...

Increased Body Temperature01:25

Increased Body Temperature

7.5K
A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Increased pulse rate01:17

Increased pulse rate

1.2K
Tachycardia is a condition marked by an abnormally fast or irregular heart rate, surpassing the typical resting rate. In adults, tachycardia is characterized by a pulse rate ranging from 100 to 180 beats per minute. The increased heart rate can result in inadequate blood flow to various body parts, ultimately diminishing the oxygen supply to organs and tissues.
Many factors can elevate the risk of developing tachycardia. These include advanced age, a family history of arrhythmias, and an...

Field Effect Transistor01:29

Field Effect Transistor

1.2K
Field-effect transistors (FETs) are integral to electronic circuits and distinguished by their three-terminal setup: the gate, drain, and source. These transistors operate as unipolar devices, which utilize either electrons or holes as charge carriers, in contrast to bipolar transistors, which use both types of carriers. The primary function of the FET is to modulate the flow of these carriers from the source to the drain through a channel. The voltage difference between the gate and source...

Summary

Field hockey players exhibit greater body asymmetry in bone density, mass, and spinal mobility compared to non-athletes. This highlights the need for monitoring athletes to prevent musculoskeletal injuries.

Area of Science:

  • Sports Medicine
  • Biomechanics
  • Human Morphology

Background:

  • Field hockey players adopt a semi-crouched posture, increasing their risk of musculoskeletal disorders.
  • Understanding body asymmetry is crucial for injury prevention in athletes.

Purpose of the Study:

  • To investigate how field hockey influences morphological and functional body asymmetry.
  • To compare asymmetry in athletes versus control participants.

Main Methods:

  • Dual-energy X-ray absorptiometry (DXA) for bone mineral density, fat mass, and lean mass.
  • Electrogoniometric system to measure spinal range of motion (cervical, thoracic, lumbar).
  • Comparison of antimeric (right vs. left) differences between field hockey players and controls.

Main Results:

  • Field hockey players showed more pronounced left-sided dominance in morphological characteristics (bone density, fat, lean mass).
  • Athletes displayed right-sided functional superiority, while controls showed left-sided functional traits.
  • Spinal side-bending asymmetry increased from cervical to lumbar regions in athletes, with thoracic rotation being the most asymmetric.

Conclusions:

  • Field hockey participation leads to significant morphological and functional asymmetries.
  • Monitoring athletes for pronounced asymmetries is vital for preventing sports-related injuries and health issues.
