The Adult ADHD Self-Report Scale (ASRS) Symptom Checklist is a self-reported questionnaire used to assist in the diagnosis of adult ADHD.Attention Deficit Hyperactivity Disorder is a neurological disorder that can present itself not only in childhood, but also adolescence and adulthood.
Although recent studies have indicated that parental warmth, praise, and quality of relationship are associated with reductions of behavior problems in autistic adolescents and adults, and that parental criticisms are associated with maladaptive behaviors and symptoms, these ideas are distinct from the refrigerator mother hypothesis.

A defrost timer taken out of a household refrigerator. The defrost mechanism in a refrigerator heats the cooling element (evaporator coil) for a short period of time and melts the frost that has formed on it. [1] The resulting water drains through a duct at the back of the unit. Defrosting is controlled by an electric or electronic timer.
A large domestic refrigerator stands as tall as a person and may be about one metre (3 ft 3 in) wide with a capacity of 0.6 m 3 (21 cu ft). Refrigerators and freezers may be free standing, or built into a kitchen. The refrigerator allows the modern household to keep food fresh for longer than before.
The Fridge Gate method is a theoretical application of using a single logic gate to drive a refrigerator in the most energy efficient way possible without violating the laws of thermodynamics. It operates on the fact that there are two energy states in which a particle can exist: the ground state and the excited state.
A 3 He/ 4 He dilution refrigerator is a cryogenic device that provides continuous cooling to temperatures as low as 2 mK, with no moving parts in the low-temperature region. [ 1 ] [ 2 ] The cooling power is provided by the heat of mixing of the helium-3 and helium-4 isotopes.
Defrosting a freezer with an improvised water collection method. In refrigerators, defrosting (or thawing) is the removal of frost and ice.. A defrosting procedure is generally performed periodically on refrigerators and freezers to maintain their operating efficiency.
A thermal expansion valve is a key element to a heat pump; this is the cycle that makes air conditioning, or air cooling, possible.A basic refrigeration cycle consists of four major elements: a compressor, a condenser, a metering device and an evaporator.
