Nuclear Power02:36

Nuclear Power

7.7K
Controlled nuclear fission reactions are used to generate electricity. Any nuclear reactor that produces power via the fission of uranium or plutonium by bombardment with neutrons has six components: nuclear fuel consisting of fissionable material, a nuclear moderator, a neutron source, control rods, reactor coolant, and a shield and containment system.
Nuclear Fuels
Nuclear fuel consists of a fissile isotope, such as uranium-235, which must be present in sufficient quantity to provide a...

Diamagnetic Shielding of Nuclei: Local Diamagnetic Current01:14

Diamagnetic Shielding of Nuclei: Local Diamagnetic Current

847
An applied magnetic field causes the electrons present in the molecule to circulate, setting up a local diamagnetic current within the molecule. The local diamagnetic current arising from circulating sigma-bonding electrons induces a magnetic field, Blocal that opposes the applied magnetic field, B0. The effective magnetic field experienced by these nuclei is given by the difference between the applied and local magnetic fields in a phenomenon called local diamagnetic shielding. Essentially,...

Radiation: Applications01:17

Radiation: Applications

1.1K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Schottky Barrier Diode01:27

Schottky Barrier Diode

327
Schottky barrier diodes are specialized semiconductor devices characterized by their unique construction. This construction involves combining a metal layer with a moderately doped n-type semiconductor material. This combination leads to the formation of a Schottky barrier, a pivotal element that defines the diode's operational characteristics. The core functionality of Schottky barrier diodes is their capacity to allow current to flow in only one direction due to their distinctive...

Transmission-based Precautions II: Airborne and Protective Environment

1.2K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Equipotential Surfaces and Conductors01:16

Equipotential Surfaces and Conductors

3.4K
For a conductor in which all charges are at rest, the conductor's surface is equipotential. The electric field is always perpendicular to equipotential surfaces. Therefore, in a conductor with static charges, the electric field just outside the conductor is always perpendicular to the conductor's surface. Any tangential component of the electric field will cause charges to move inside the conductor, which will violate the electrostatic nature of the system. In an electrostatic...

Summary
This summary is machine-generated.

Chest shielding during phototherapy for preterm infants does not prevent patent ductus arteriosus (PDA) or affect treatment efficacy. Routine chest shielding is not recommended for these infants.

Area of Science:

  • Neonatal Medicine
  • Pediatric Cardiology
  • Phototherapy Research

Background:

  • Patent ductus arteriosus (PDA) is common in preterm infants.
  • Phototherapy is a standard treatment for neonatal jaundice.
  • The use of chest shielding during phototherapy is debated for its potential impact on PDA.

Purpose of the Study:

  • To determine if chest shielding during phototherapy reduces symptomatic PDA in preterm infants.
  • To assess the effect of chest shielding on phototherapy efficacy.
  • To clarify inconsistent findings in previous research.

Main Methods:

  • A double-blinded randomized controlled trial (RCT) was conducted.
  • Preterm infants undergoing phototherapy were included.
  • Symptomatic PDA incidence and phototherapy effectiveness were measured.

Main Results:

  • Chest shielding did not significantly reduce the incidence of symptomatic PDA.
  • Phototherapy efficacy remained unaffected by the presence or absence of chest shielding.
  • Phototherapy may induce cardiovascular changes like vasodilation.

Conclusions:

  • Routine chest shielding is not beneficial for preventing symptomatic PDA in preterm infants during phototherapy.
  • Current evidence does not support the regular use of chest shielding.
  • Further research into phototherapy's cardiovascular effects is warranted.
