Jacqueline Auriol was France’s most famous woman aviator and one of the world’s leading military test pilots of the 1950s and 1960s. The daughter of a wealthy shipbuilder, she was born Jacqueline Marie-Thérèse Suzanne Douet on November 5, 1917, in Challans, a small town in France. How did Jacqueline AuriolRead More →
Peripheral resistance is determined by three factors: Autonomic activity: sympathetic activity constricts peripheral arteries. Pharmacologic agents: vasoconstrictor drugs increase resistance while vasodilator drugs decrease it. Blood viscosity: increased viscosity increases resistance. What happens when total peripheral resistance increases? Vascular resistance is used to maintain organ perfusion. In certain disease states,Read More →
Bacteria can develop resistance to disinfectants over time either by acquisition of exogenous mobile genetic elements or through the process of intrinsic genetic adaption. Does antibiotic resistance correlate with resistance to antiseptics and disinfectants? There are links between disinfectant resistance and antibiotic resistance. Some biocides have the ability to selectRead More →
The unit for resistance is an ohm and is given the symbol Ω (upper case Greek omega). Rearranging I = V/R gives R = V/I, and so the units of resistance are 1 ohm = 1 volt per ampere: 1Ω=1VA 1 Ω = 1 V A . How do youRead More →
Each time you can calculate the unknown resistance using the formula:unknown resistance(a)=known resistance(b)*L/M. The value is found to be the same for all values of known resistance. How do you find the resistance of a Wheatstone bridge? Firstly, combine the series resistances and form the ideal circuit of a WheatstoneRead More →
Weight and Resistance Training Weight training is also an important component of burning off belly fat. Since muscles burn off more calories than fat does when the body is at rest, having more muscle tone can help you to burn off more fat. Is walking or resistance training better forRead More →
Ignoring channel-length modulation is equivalent to assuming that the small-signal output resistance of the FET is infinite. It follows, then, that higher output resistance is desirable if we want a MOSFET to behave more like the idealized component in which drain current is not influenced by drain-to-source voltage. What isRead More →
