In Portuguese middle-schools, a five-point grading scale is used, where: 5 (very good or excellent) is the best possible grade (90-100%), 4 (good) (70-89%),
The number of steps to calculate the GCD of two natural numbers, a and b, may be denoted by T(a, b). [96] If g is the GCD of a and b, then a = mg and b = ng for two coprime numbers m and n. Then T(a, b) = T(m, n) as may be seen by dividing all the steps in the Euclidean algorithm by g. [97]
The European Qualifications Framework (EQF) acts as a translation device to make national qualifications more readable across Europe, promoting workers' and learners' mobility between countries and facilitating their lifelong learning.
The greatest common divisor (GCD) of integers a and b, at least one of which is nonzero, is the greatest positive integer d such that d is a divisor of both a and b; that is, there are integers e and f such that a = de and b = df, and d is the largest such integer.
In the beginnings of the Portuguese nationality, the Christian clergy was the main player in the educational endeavour. Portuguese universities have existed since 1290.Within the scope of the Portuguese Empire, the Portuguese founded in 1792 the oldest engineering school of Latin America (the Real Academia de Artilharia, Fortificação e Desenho), as well as the oldest medical college of Asia ...
During the given timespan, the number of foreigners in Portugal fell from 446,333 to 388,731, recording a 12.89% loss in eight years. In fact, Portugal was particularly hit by the 2008 Global recession. It is indeed worth noting that between 2008 and 2013, Portugal experienced a notable uptick in its unemployment rate, escalating from 7.6% to ...
In theoretical and computational chemistry, a basis set is a set of functions (called basis functions) that is used to represent the electronic wave function in the Hartree–Fock method or density-functional theory in order to turn the partial differential equations of the model into algebraic equations suitable for efficient implementation on a computer.
In crystallography, atomic packing factor (APF), packing efficiency, or packing fraction is the fraction of volume in a crystal structure that is occupied by constituent particles.
