When will the incidence and prevalence of a disease be equal?
The incidence will equal the prevalence when the duration of the disease is equal to the time period over which the incidence is measured.
Does bipolar disorder effect men or women more?
The prevalence rate of bipolar disorder appears to be equal among men and women
How do you calculate average duration in epidemiology?
P/1-P where 1-P is the prevalence odds. This is true for prevalence values that are bigger. Prevalence=Incidence rate x Duration (true for small prevalences)
True power divided by apparent power?
Real Power: The actual power in Watts or K-Watts in AC or DC Circuits Apparent power: The Power in Inductive or Capacitive Circuits have Phase Lag & Lead measured in Volt Amperes VA or Kilo Volt Amperes KVA
What is the formula of prevalence?
True Cases divided by the total Number in the population.
Is it true that White males have the highest prevalence of alcohol use?
no stop being racist
The prevalence of depression and rates of suicide are increasing?
Wrong. Both are increasing.
An apparent contradiction that is actually true is a?
Paradox
What is the ratio of apparent power to true power?
The ratio of apparent power to true power is called 'admittance', expressed in siemens. Admittance is the inverse of impedance.
Is reactive power greater than true power?
Use a wattmeter, as it only reads 'real power' of your load. Use an ammeter and a voltmeter, and the product of the two readings will give you 'apparent power' of your load. Since apparent power is the vector sum of real power and reactive power, use the following equation to find the reactive power of your load: (reactive power)2 = (apparent power)2 - (real power)2
What is apparent solubility of drug?
Reference 11: Apparent solubility refers to the concentration of material at apparent equilibrium (supersaturation). Apparent solubility is distinct from true thermodynamic solubility, which is reached at injinite equilibrium time.
What affect the phase angle?
Apparent power is the vector sum of a load's true power and its reactive power. If you draw a 'power diagram', the phase angle will be the angle between the true power and the apparent power. If true power is fixed, then increasing the phase angle will result in a greater value of apparent power.
