A short circuit fault current can, within milliseconds, be thousands of times larger than the normal operating current of the system. [2] Damage from short circuits can be reduced or prevented by employing fuses , circuit breakers , or other overload protection , which disconnect the power in reaction to excessive current.
Bipolar disorder is among the top 20 causes of disability worldwide and leads to substantial costs for society. [26] Due to lifestyle choices and the side effects of medications, the risk of death from natural causes such as coronary heart disease in people with bipolar disorder is twice that of the general population.

In electronics, a latch-up is a type of short circuit which can occur in an integrated circuit (IC). More specifically, it is the inadvertent creation of a low-impedance path between the power supply rails of a MOSFET circuit, triggering a parasitic structure which disrupts proper functioning of the part, possibly even leading to its destruction due to overcurrent.
IPSRT was studied as one of three intensive psychosocial treatments in the NIMH-funded Systematic Treatment Enhancement Program for Bipolar Disorder [18] (STEP-BD). STEP-BD was a long-term outpatient study investigating the benefits of psychotherapies in conjunction with pharmacotherapy in treating episodes of depression and mania, as well as ...
Bipolar disorder is a mental disorder with cyclical periods of depression and periods of elevated mood. [1] The elevated mood is significant and is known as mania, a severe elevation that can be accompanied by psychosis in some cases, or hypomania, a milder form of mania.
Psychological resilience, or mental resilience, is the ability to cope mentally and emotionally with a crisis, or to return to pre-crisis status quickly. [1]The term was popularized in the 1970s and 1980s by psychologist Emmy Werner as she conducted a forty-year-long study of a cohort of Hawaiian children who came from low socioeconomic status backgrounds.
A resistor removed from a high voltage tube circuit shows damage from voltaic arcing on the resistive metal oxide layer. Resistors can fail open or short, alongside their value changing under environmental conditions and outside performance limits. Examples of resistor failures include: Manufacturing defects causing intermittent problems.
Selectivity, also known as circuit breaker discrimination, is the coordination of overcurrent protection devices so that a fault in the installation is cleared by the protection device located immediately upstream of the fault. The purpose of selectivity is to minimize the impact of a failure on the network.
