General External Flow Characteristics01:26

General External Flow Characteristics

554
The study of external flow is essential for creating structures and objects that interact efficiently and safely with moving fluids, such as air or water. When a body is immersed in a flowing fluid, it experiences two primary forces: drag, which opposes motion along the flow direction, and lift, which acts perpendicular to the flow. The shape, size, and orientation of the object influence these forces.Streamlined and Blunt Bodies in External FlowObjects in fluid flow are classified as...

Work Done on a System by External Force

3.0K
The work done by an external force on a particle changes its kinetic energy. However, internal forces must also be considered for a system of interacting particles. The potential energy formulation helps formulate the effect of internal forces. The net work done by an external force can be written in terms of the total change of mechanical energy, which includes both kinetic and potential energies.
In the presence of a non-conservative opposing force, like friction, some part of the work done...

Data Reporting and Recording01:24

Data Reporting and Recording

5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Internal and External Forces01:12

Internal and External Forces

16.4K
Newton's first law states that a net external force causes a change in motion. External forces act on an object or system, originating outside of the object or system. In contrast, internal forces originate inside the system of interest and do not lead to any acceleration. In simpler words, internal forces are forces that act on one part of an object and are exerted by another part of the same object. External forces are forces that act on an object due to some other object. Therefore, when...

External and Internal Respiration01:24

External and Internal Respiration

7.7K
External respiration occurs in the lungs, and it is the first step in the journey of oxygen inside the body. When we inhale, oxygen enters our lungs and diffuses across the thin alveolar membrane. The alveoli are tiny, air-filled sacs that provide a vast surface area for gas exchange. Oxygen in the alveoli has a higher partial pressure (105 mmHg) than in the adjacent pulmonary capillaries (40 mmHg), establishing a pressure gradient. As a result, oxygen molecules move from the alveoli into the...

External Anatomy of the Kidney01:21

External Anatomy of the Kidney

3.9K
The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

Area of Science:

  • Dentistry
  • Oral Pathology
  • Endodontics

Background:

  • External apical root resorption (EARR) is a pathological process affecting the tooth apex.
  • Idiopathic EARR, without a clear local cause, is uncommon.
  • Systemic factors are increasingly recognized as potential contributors to EARR.

Observation:

  • This report details an unusual case of generalized idiopathic EARR.
  • The condition affected all four quadrants of the patient's dentition.
  • The patient had a significant medical history including intravenous drug addiction and liver disease.

Findings:

  • The case presents a unique manifestation of multiple idiopathic EARR.
  • A correlation between systemic conditions (drug addiction, liver disease) and EARR is suggested.
  • Review of literature supports the potential for systemic etiologies in EARR.

Implications:

  • This case underscores the importance of considering systemic health in diagnosing and managing EARR.
  • Further research is warranted to elucidate the specific mechanisms linking systemic diseases to EARR.
  • Clinicians should be aware of potential systemic associations in patients presenting with unexplained root resorption.
