Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

487
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:

Design Example: Calculating Safe Diameter for Wind-Exposed Disc01:17

Design Example: Calculating Safe Diameter for Wind-Exposed Disc

357
Assessing safety in wind-exposed installations is crucial to preventing potential failures. This example explores the calculation and design adjustments needed to mount a circular disc on a building facade, where wind forces are a primary concern. A 4-meter diameter disc was initially designed as an aesthetic feature facing winds at a velocity of 25 meters per second, with an air density of 1.25 kilograms per cubic meter. Given these conditions, the drag force on the disc was determined using...

Drug Dosing: Infants and Children

277
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Nerve Supply of the GI Tract01:27

Nerve Supply of the GI Tract

3.5K
The neuronal supply to the gastrointestinal (GI) tract is essential for regulating various functions, including digestion, absorption, and movement of food. This intricate network of nerves is known as the enteric nervous system (ENS), often referred to as the "second brain" of the body.
The enteric nervous system consists of two major plexuses: the myenteric plexus (Auerbach's plexus) and the submucosal plexus (Meissner's plexus). These plexuses are located within the layers of...

Spinal Nerves: Plexus II01:21

Spinal Nerves: Plexus II

2.3K
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Cranial Nerves: Types Part I01:14

Cranial Nerves: Types Part I

5.1K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

Area of Science:

  • Neonatal Medicine
  • Pediatric Neurology
  • Medical Imaging

Background:

  • Early detection of raised intracranial pressure (ICP) is crucial for neurodevelopmental outcomes in preterm infants.
  • Invasive ICP monitoring is not recommended for neonates.
  • Optic nerve sheath diameter (ONSD) ultrasonography presents a noninvasive alternative for ICP evaluation.

Purpose of the Study:

  • To establish normative ranges of ONSD in preterm infants.
  • To investigate the correlation between ONSD and corrected gestational age.
  • To assess the feasibility of ONSD as a noninvasive ICP indicator in neonates.

Main Methods:

  • Prospective cohort pilot study of preterm infants in the NICU.
  • Ultrasound imaging of ONSD using a 20-5 MHz linear array transducer.
  • Measurement of ONSD 3 mm behind the globe; interrater reliability assessed.

Main Results:

  • 114 scans were performed on 12 preterm infants (median corrected gestational age 33 weeks).
  • Corrected gestational age was the strongest predictor for ONSD.
  • Substantial interrater reliability (Qc = 0.97) was demonstrated.

Conclusions:

  • ONSD in preterm infants shows a strong correlation with corrected gestational age.
  • Preliminary ONSD ranges were established based on gestational age.
  • Further validation with other imaging modalities is needed before clinical application for abnormal ranges.
