Work Done on a System by External Force01:11

Work Done on a System by External Force

2.9K
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...

Cavity Drainage and Flashings in Masonry walls01:20

Cavity Drainage and Flashings in Masonry walls

427
Typically, a cavity wall consists of two wythes separated by a gap of at least 2 inches, which may contain insulation while still maintaining a minimum clear space of 1 inch to facilitate adequate drainage. Advanced methods like the insertion of a continuous drainage mat can further reduce this space while ensuring effective moisture expulsion.
Weep holes, strategically placed at the base of the cavity, are critical for draining accumulated water. These openings are created by leaving head...

External and Internal Respiration01:24

External and Internal Respiration

7.2K
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...

Internal and External Forces01:12

Internal and External Forces

16.1K
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 Anatomy of the Kidney01:21

External Anatomy of the Kidney

3.5K
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...

External Female Genitals

30.7K
The vulva encompasses the external structures of the female reproductive system. At the forefront is the monpubis, a cushion of fatty tissue atop the pubic bone. Once puberty sets in, this area typically grows hair. Extending from just behind the mons pubis are the labia majora (labia = 'lips'; majora = 'larger'), which are larger skin fs olds coated with hair. Nestled within are the labia minora (labia = 'lips'; minora = 'smaller'), which are thinner, more...

    Area of Science:

    • Ophthalmology
    • Surgical Innovation

    Background:

    • Choroidal effusions can occur post-vitrectomy, especially in patients with glaucoma tube shunts.
    • Medical management of these effusions is often ineffective, necessitating alternative treatments.

    Purpose of the Study:

    • To describe a minimally invasive transconjunctival choroidal drainage technique.
    • To evaluate the efficacy and safety of this procedure for managing post-vitrectomy choroidal effusions in a glaucoma patient.

    Main Methods:

    • A transconjunctival choroidal drainage was performed under widefield visualization.
    • The glaucoma tube shunt was temporarily blocked with viscoelastic to manage intraocular pressure.

    Main Results:

    • The procedure successfully resolved symptomatic choroidal effusions.
    • Conjunctival preservation was achieved.
    • Normal intraocular pressure was restored.

    Conclusions:

    • Minimally invasive transconjunctival choroidal drainage is a viable option for refractory choroidal effusions post-vitrectomy.
    • This technique offers benefits such as conjunctival preservation and effective IOP management.
