Question: How many costumers do this company have that is a "global e-learning player" along with Element K?

A distributed element filter is an electronic filter in which capacitance, inductance and resistance (the elements of the circuit) are not localised in discrete capacitors, inductors and resistors as they are in conventional filters.  Its purpose is to allow a range of signal frequencies to pass, but to block others.  Conventional filters are constructed from inductors and capacitors, and the circuits so built are described by the lumped element model, which considers each element to be "lumped together" at one place.  That model is conceptually simple, but it becomes increasingly unreliable as the frequency of the signal increases, or equivalently as the wavelength decreases.  The distributed element model applies at all frequencies, and is used in transmission line theory; many distributed element components are made of short lengths of transmission line.  In the distributed view of circuits, the elements are distributed along the length of conductors and are inextricably mixed together.  The filter design is usually concerned only with inductance and capacitance, but because of this mixing of elements they cannot be treated as separate "lumped" capacitors and inductors.  There is no precise frequency above which distributed element filters must be used but they are especially associated with the microwave band (wavelength less than one metre). <SEP> Potassium–argon dating, abbreviated K–Ar dating, is a radiometric dating method used in geochronology and archaeology.  It is based on measurement of the product of the radioactive decay of an isotope of potassium (K) into argon (Ar).  Potassium is a common element found in many materials, such as micas, clay minerals, tephra, and evaporites.  In these materials, the decay product Ar is able to escape the liquid (molten) rock, but starts to accumulate when the rock solidifies (recrystallizes).  The amount of Argon sublimation that occurs is a function of the purity of the sample, the composition of the mother material, and a number of other factors.  These factors introduce error limits on the upper and lower bounds of dating, so that final determination of age is reliant on the environmental factors during formation, melting, and exposure to decreased pressure and/or open-air.  Time since recrystallization is calculated by measuring the ratio of the amount of Ar accumulated to the amount of K remaining.  The long half-life of K allows the method to be used to calculate the absolute age of samples older than a few thousand years. <SEP>  The company has a content library (about 4,000 courses in total), mainly in the business skills and IT professional area but also for social care, hospitality and more general compliance training in the UK. MindLeaders is an e-learning and organizational development company with a global headquarters in Dublin, Ireland and offices in the UK, US, South Africa and Australia which has been described by Bersin as a "global e-learning player" along with Skillsoft and Element K (which was acquired by Skillsoft in 2011).  These courses are typically accessed through one of two learning management system (LMS) platforms owned by the company.  Whilst not a widely known brand, MindLeaders content is resold by consumer-facing channel partners including learndirect, Monster.com and Cornerstone OnDemand. <SEP> Skillsoft is an American educational technology company that produces learning management system software and content.  s of 2014 , it was one of the world's largest corporate training providers, with 10,000 customers, 60 million users, and 2,400 employees.
