Electrical Current01:10

Electrical Current

6.9K
Electrical current is defined as the rate at which charge flows. When there is a large current present, such as that used to run a refrigerator, a large amount of charge moves through the wire in a small amount of time. If the current is small, such as that used to operate a handheld calculator, a small amount of charge moves through the circuit over a long period of time. The SI unit for current is the ampere (A), named for the French physicist André-Marie Ampère (1775–1836).

Significance of Displacement Current01:27

Significance of Displacement Current

5.8K
A displacement current is analogous to a real current in Ampère's law, participating in Ampère's law the same way as the usual conduction current. However, it is produced by a changing electric field. Displacement current is defined in terms of a time-varying electric field, and also has an associated displacement current density. By adding a term accounting for displacement current, Maxwell modified the existing Ampère's law, which is now called generalized Ampère's law.

Current Trends in Nursing II

3.4K
Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...

Charge and Current01:14

Charge and Current

5.4K
Electric charge is the most fundamental quantity in an electric circuit. The effects of electric charge are encountered daily, such as when a wool sweater sticks to the human body or when a person receives a shock while walking on a carpet.
Charge is an inherent property of the atomic particles that make up matter and is measured in units called coulombs (C). Matter is composed of atoms, each consisting of electrons, protons, and neutrons. Electrons have a negative charge (-e), while protons...

Current Dividers01:10

Current Dividers

1.0K
In parallel electrical connections, resistors are linked between the same pair of nodes, creating an equal voltage across each resistor. Kirchhoff's current law is applied to these connections, establishing that the sum of currents through these resistors equals the source current. Utilizing Ohm's law, the source current is determined as the product of the source voltage and the sum of the reciprocals of individual resistances. This relationship simplifies the process of finding the current...

Area of Science:

  • Hepatobiliary Surgery
  • Surgical Oncology
  • Gastroenterology

Background:

  • Liver resection is a primary treatment for liver malignancies.
  • Significant improvements in surgical outcomes are attributed to enhanced patient selection, procedural development, and perioperative care.
  • Safe liver resection is increasingly accessible globally.

Purpose of the Study:

  • To review four key current topics in liver resection: anatomical liver resection, laparoscopic liver resection, staged liver resection, and chemotherapy-induced liver injury.
  • To emphasize the critical balance between treatment efficacy and patient safety in surgical planning.
  • To highlight areas requiring further research and evidence generation.

Main Methods:

  • Review of recent series focusing on safety and efficacy.
  • Analysis of advancements in operative procedures and perioperative management.
  • Identification of current challenges and future research directions in liver resection.

Main Results:

  • Progress in liver resection has led to significantly improved patient outcomes.
  • Four critical topics (anatomical, laparoscopic, staged resection, and chemotherapy-induced liver injury) are identified as areas for continued development.
  • The need for standardized optimal procedure selection and risk evaluation is emphasized.

Conclusions:

  • Liver resection techniques and perioperative management have advanced, improving safety and efficacy.
  • Further robust evidence is required to standardize approaches to anatomical, laparoscopic, and staged liver resections.
  • Addressing chemotherapy-induced liver injury is crucial for optimizing patient management and outcomes in liver cancer treatment.
