As the data obtained from the medical centres says that the time it takes for an object to cool down from 100º C to 50ºC. It is a rule that a smaller object cools faster than a larger object of the same material and shape which means that the smaller target has a shorter thermal relaxation time. This fact is important when the tissue needs to be heated to a desired temperature at a certain fluence setting. If the pulse width is too long, the tissue will start cooling itself via thermal conduction prior to the completion of a pulse causing a negative clinical effect. The second parameter that should be taken into consideration when estimating the TRT is the shape of the target tissue. A sphere (skin cells) having 360 degrees of cooling surface area cools faster than a cylinder (hair follicles). This allows hair follicle to retain its heat while the skin cells can cool itself much more efficiently. For this reason, parameters can be selected to destroy the follicle without causing damage to the skin. For targeting smaller structures, a shorter pulse duration and higher fluence are recommended.

thermal, and kinetic
Relation between relaxation time and mean collision time?
The relaxation time is related to the mean collision time through the expression: relaxation time = mean collision time / (1 - f), where f is the fraction of collisions that result in thermalization. The mean collision time represents the average time between particle collisions, while the relaxation time is the time it takes for a system to reach thermal equilibrium after a perturbation.
What is thermal relaxation?
Thermal relaxation is the process by which a system transitions to a lower energy state by dissipating excess heat. This typically involves the transfer of energy from the system to its surroundings through mechanisms such as conduction, convection, or radiation. Thermal relaxation helps the system maintain thermodynamic equilibrium.
What is beta relaxation?
This is the early relaxation of the particles. It corresponds to the vibrations of the particles around their equilibrium position, and is not very informative in itself : the particles are stuck by their neighbors, and this leads to a plateau of relaxation (beta relxation is before the plateau).The late relaxation is called alpha relaxation, and is much more inofrmative on the dynamical heterogeneities at play for instance in glass formers.
What is momentum relaxation time?
Momentum
What did the early maoris use thermal pools for?
The early Maoris used thermal pools for bathing, cooking, and healing purposes. The geothermal hot springs were believed to have medicinal properties and were used for relaxation and treating various ailments.
Why collision time and relaxation time are not equal in anisotropic medium?
average time, an electron spends between two successive collision, is called relaxation time and time spent by electron at point of contact, is called collision time
What is an underground thermal pool called?
An underground thermal pool is called a geothermal pool. These pools are heated by geothermal activity deep within the Earth's crust, providing a natural source of warm water for relaxation and therapeutic benefits.
What is R and R time?
Rest and Relaxation or, Rest and Recreation.
What are Drift velocity and momentum relaxation time?
Drift velocity refers to a particle's average velocity being influenced by its electric field. Momentum relaxation time is the time required for the inertial momentum of a particle to become negligible.
How do I calculate the relaxation time of a charge carrier?
no idea,help me as well
What does 'leiure' mean?
Leisure means time available for ease and relaxation.
What strategies can be implemented to ensure a seamless transition from work to relaxation?
To ensure a smooth transition from work to relaxation, you can implement strategies such as setting boundaries between work and personal time, creating a designated relaxation space, practicing mindfulness or meditation, engaging in physical activity, and establishing a routine that includes time for relaxation activities. These strategies can help you disconnect from work and unwind effectively.
