In microeconomics, a production–possibility frontier (PPF), production possibility curve (PPC), or production possibility boundary (PPB) is a graphical representation showing all the possible options of output for two that can be produced using all factors of production, where the given resources are fully and efficiently utilized per unit time.
The production possibilities frontier (PPF) for guns versus butter. Points like X that are outside the PPF are impossible to achieve. Points such as B, C, and D illustrate the trade-off between guns and butter: at these levels of production, producing more of one requires producing less of the other.
Damage to the posterior parietal cortex can produce a variety of sensorimotor deficits, including deficits in the perception and memory of spatial relationships, inaccurate reaching and grasping, in the control of eye movement, and inattention. The two most striking consequences of PPC damage are apraxia and hemispatial neglect. [1]
Pressure perturbation calorimetry (PPC) is a technique closely related to isothermal titration calorimetry (ITC) and differential scanning calorimetry (DSC). In brief, PPC measures heat changes associated with dilute aqueous solutions of proteins or other biomolecules in response to introduction of relatively small pressure perturbations (± 5 atm).
This is called a "cavitate bell" because the rapid acceleration of the ship's propeller will cause the water around it to cavitate, causing a lot of noise and wear on the propellers. Such noise is undesirable during conflicts because it can give away a vessel's position.
De-dollarization — when countries shift away from the greenback as the currency for reserves, transactions and to measure value — has become a hot topic in recent years, with countries like ...
The fuel efficiency and working principle of a PPC engine resemble those of Diesel engine, but the PPC engine can be run with a variety of fuels. Also, the partially premixed charge burns clean. [6] Challenges with using gasoline in a PPC engine arise due to the low lubricity of gasoline and the low cetane value of gasoline.
The shift also is taking place as China’s economic growth has been weak and global businesses are looking to diversify following supply chain disruptions during the pandemic.
