Internal Energy

Internal Energy

The total of all possible kinds of energy present in a substance is called the internal energy (U), sometimes symbolized as E. Suppose a system with initial internal energy, Uinitial, undergoes a change in energy (transfer of work or heat), and the final internal energy of the system is Ufinal. Change in internal energy equals the difference between Ufinal and Uinitial.

Internal Energy

Internal Energy

The internal energy of a thermodynamic system is the sum of the kinetic and potential energies of all the molecules or entities in the system. The kinetic energy of an individual molecule includes contributions due to its rotation and vibration, as well as its translational energy. The potential energy is associated only with the interactions between one molecule and the other molecules of the system. Neither the system's location nor its motion is of any consequence as far as the internal...

Internal Receptors

Internal Receptors

Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Fixed Action Patterns

Fixed Action Patterns

A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

International System of Units

International System of Units

The International System of Units, known as the SI system, is a universally accepted measurement system recognized and used worldwide. The SI system is based on a set of three base units considered absolute, and their values do not change with location. These base units are meters, kilograms, and seconds.
Prefixes are used to define both larger and smaller quantities in the SI system. For example, milli, micro, and nano define smaller quantities, while kilo, mega, and giga are used to define...

Internal and External Forces

Internal and External Forces

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...

Area of Science:

Forensic Pathology
Trauma Analysis
Autopsy

Background:

Patterned bruising typically involves external skin injuries.
Internal organ bruising without corresponding cutaneous signs is rare.
Tramline bruising is a specific pattern usually associated with direct impact.

Observation:

A 23-year-old male died by suicide via a fall from a bridge.
Autopsy revealed unusual "tramline" bruising on the right lobe of the liver.
No corresponding external tramline bruising was present on the skin.

Findings:

The internal tramline liver bruising was caused by fractured ribs.
Ribs were displaced against the liver capsule due to severe thoracic and vertebral trauma.
The mechanism involved blunt force trauma from intermediate impact during the fall.

Implications:

This case expands the understanding of internal blunt force trauma patterns.
It demonstrates how internal injuries can mimic external patterns without external signs.
Highlights the importance of thorough autopsy in cases of severe trauma.
