The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of a vacuum. A dielectric is an insulating material, and the dielectric constant of an insulator measures the ability of the insulator to store electric energy in an electrical field.
Permittivity is a material's property that affects the Coulomb force between two point charges in the material

Sedimentation potential occurs when dispersed particles move under the influence of either gravity or centrifugation in a medium. This motion disrupts the equilibrium symmetry of the particle's double layer. While the particle moves, the ions in the electric double layer lag behind due to the liquid flow

Settling is the process by which particulates move towards the bottom of a liquid and form a sediment. Particles that experience a force, either due to gravity or due to centrifugal motion will tend to move in a uniform manner in the direction exerted by that force. For gravity settling, this means that the particles will tend to fall to the bottom of the vessel, forming sludge or slurry at the vessel base

In chemistry, a suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye, usually must be larger than one micrometer, and will eventually settle, although the mixture is only classified as a suspension when and while the particles have not settled out.
Properties
A suspension is a heterogeneous mixture in which the solid particles do not dissolve, but get suspended throughout the bulk of the solvent, left floating around freely in the medium

Syneresis (also spelled 'synæresis' or 'synaeresis'), in chemistry, is the extraction or expulsion of a liquid from a gel, such as when serum drains from a contracting clot of blood. Another example of syneresis is the collection of whey on the surface of yogurt. Syneresis can also be observed when the amount of diluent in a swollen polymer exceeds the solubility limit as the temperature changes

In colloidal chemistry, the surfactant’s critical micelle concentration (CMC) plays a factor in Gibbs free energy of micellization. The exact concentration of the surfactants that yield the aggregates being thermodynamically soluble is the CMC. The Krafft temperature determines the solubility of the surfactants which in turn is the temperature that CMC is achieved

Water-in-water (W/W) emulsion is a system that consists of droplets of water-solvated molecules in another continuous aqueous solution; both the droplet and continuous phases contain different molecules that are entirely water-soluble. As such, when two entirely aqueous solutions containing different water-soluble molecules are mixed, water droplets containing predominantly one component are dispersed in water solution containing another component. Recently, such a water-in-water emulsion was demonstrated to exist and be stable from coalescence by the separation of different types of non-amphiphilic, but water-soluble molecular interactions

The Cambridge Neuropsychological Test Automated Battery (CANTAB), originally developed at the University of Cambridge in the 1980s but now provided in a commercial capacity by Cambridge Cognition, is a computer-based cognitive assessment system consisting of a battery of neuropsychological tests, administered to subjects using a touch screen computer. The CANTAB tests were co-invented by Professor Trevor Robbins and Professor Barbara Sahakian. The 25 tests in CANTAB examine various areas of cognitive function, including:
general memory and learning,
working memory and executive function,
visual memory,
attention and reaction time (RT),
semantic/verbal memory,
decision making and response control

The cervical enlargement corresponds with the attachments of the large nerves which supply the upper limbs.
Located just above the brachial plexus, it extends from about the fifth cervical to the first thoracic vertebra, its maximum circumference (about 38 mm. ) being on a level with the attachment of the sixth pair of cervical nerves

Collier's sign (also known as Collier's tucked lid sign or posterior fossa stare) is bilateral or unilateral eyelid retraction.
It is an accepted medical sign of a midbrain lesion, first described in 1927 by J Collier. With the eyes in the primary position, the sclera can be seen above the cornea, and further upgaze increases the distance between the eyelids and irises

In neurophysiology, commutation is the process by which the brain's neural circuits exhibit non-commutativity.
Physiologist Douglas B. Tweed and coworkers have considered whether certain neural circuits in the brain exhibit noncommutativity and state:
In noncommutative algebra, order makes a difference to multiplication, so that

Crossmodal perception or cross-modal perception is perception that involves interactions between two or more different sensory modalities. Examples include synesthesia, sensory substitution and the McGurk effect, in which vision and hearing interact in speech perception.
Crossmodal perception, crossmodal integration and cross modal plasticity of the human brain are increasingly studied in neuroscience to gain a better understanding of the large-scale and long-term properties of the brain

Electronarcosis, also called electric stunning or electrostunning, is a profound stupor produced by passing an electric current through the brain. Electronarcosis may be used as a form of electrotherapy in treating certain mental illnesses in humans, or may be used to render livestock unconscious prior to slaughter.
History
In 1902, Stephen Leduc discovered he could produce a narcotic-like state in animals, and eventually, he tried it on himself, where he remained conscious but unable to move in a dream-like state

An electroneurogram is a method used to visualize directly recorded electrical activity of neurons in the central nervous system (brain, spinal cord) or the peripheral nervous system (nerves, ganglions). The acronym ENG is often used. An electroneurogram is similar to an electromyogram (EMG), but the latter is used to visualize muscular activity

The empty delta sign is a radiologic sign seen on brain imaging which is associated with cerebral venous sinus thrombosis. It is usually seen on magnetic resonance imaging (MRI) or computed tomography (CT) scans with contrast. It is seen as dural wall enhancement in the absence of intra-sinus enhancement (there is no enhancement in the lumen of the dural sinus)

Fogging phenomenon in computerized tomography (CT) scanning of the head is vanishing signs of an infarct on the serial CT imaging in a patient with a recent stroke. It is a reversal of the hypodensity on the CT after an acute ischemic stroke. This happens as a result of re-nourishment of the infarcted area in subacute phase about one to three weeks after the stroke

The Functional Independence Measure (FIM) is an assessment tool that aims to evaluate the functional status of patients throughout the rehabilitation process following a stroke, traumatic brain injury, spinal cord injury or cancer. Its area of use can include skilled nursing facilities and hospitals aimed at acute, sub-acute and rehabilitation care. Performed on admission to and departure from a rehabilitation hospital, it serves as a consistent data collection tool for the comparison of rehabilitation outcomes across the health care continuum
