Electrical Current

Electrical Current

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).

Self-Evaluation: Self-Enhancement and Self-Verification

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Current Density

Current Density

The total amount of current flowing through one unit value of a cross-sectional area is referred to as current density. If the current flow is uniform, the amount of current flowing through a conductor is the same at all points along the conductor, even if the conductor area varies. The current density consists of the local magnitude and direction of the charge flow, which varies from point to point. Current density is measured in amperes per meter square, and direction is defined as the net...

Eddy Currents

Eddy Currents

Since eddy currents occur only in conductors, magnets can separate metals from other materials. For example, in a recycling center, trash is dumped in batches down a ramp, beneath which lies a powerful magnet. Conductors in the trash are slowed by eddy currents, while nonmetals in the trash move on, separating from the metals. This works for all metals, not just ferromagnetic ones.
Other major applications of eddy currents appear in metal detectors and the braking systems of trains and roller...

Displacement Current

Displacement Current

Ampère's law, in its usual form, does not work in places where the current changes with time and is not steady. Thus, Maxwell suggested including an additional contribution, called the displacement current, Id, to the real conduction current I.

Charge and Current

Charge and Current

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...

Area of Science:

Urology
Sleep Medicine
Pharmacology

Background:

Nocturia significantly affects patient quality of life.
It can indicate underlying systemic diseases.
Common causes include sleep disorders, bladder storage issues, and polyuria.

Purpose of the Study:

To review the assessment and treatment of nocturia.
To highlight the role of desmopressin acetate nasal spray for nocturnal polyuria.

Main Methods:

Initial assessment involves detailed history, physical examination, and frequency-volume charts.
Pharmacological treatments include alpha-blockers and antimuscarinics for specific causes.
Desmopressin acetate nasal spray is approved for nocturia due to nocturnal polyuria.

Main Results:

Desmopressin acetate nasal spray (Noctiva™) was FDA-approved in 2017.
Clinical trials demonstrated efficacy in reducing nocturnal voids by ≥50% in up to 49% of patients.
This treatment is indicated for adults awakening at least twice nightly.

Conclusions:

Nocturia management requires identifying underlying causes.
Desmopressin acetate nasal spray offers a targeted treatment for nocturia stemming from nocturnal polyuria.
This medication improves quality of life for affected adults.
