Portable Document Format (PDF), standardized as ISO 32000, is a file format developed by Adobe in 1992 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems.
The ancient Greek understanding of physics was limited to the statics of simple machines (the balance of forces), and did not include dynamics or the concept of work. During the Renaissance the dynamics of the Mechanical Powers, as the simple machines were called, began to be studied from the standpoint of how far they could lift a load, in addition to the force they could apply, leading ...
Work has existed in all human societies, either as paid or unpaid work, from gathering natural resources by hand in hunter-gatherer groups to operating complex technologies that substitute for physical or even mental effort within an agricultural, industrial, or post-industrial society.
Work (electric field), the work done on a charged particle by an electric field; Work (thermodynamics), energy transferred by the system to its surroundings; Creative work, a manifestation of creative effort Work of art, an artistic creation of aesthetic value; Career, an individual's journey through learning, work and other aspects of life
Thermodynamic work is one of the principal kinds of process by which a thermodynamic system can interact with and transfer energy to its surroundings. This results in externally measurable macroscopic forces on the system's surroundings, which can cause mechanical work, to lift a weight, for example, [1] or cause changes in electromagnetic, [2] [3] [4] or gravitational [5] variables.
A scheme of work is a kind of plan that outlines all the learning to be covered over a given period of time (usually a term or a whole school year). [1] [2] defines the structure and content of an academic course. It splits an often-multi-year curriculum into deliverable units of work, each of a far shorter weeks' duration (e.g. two or three ...
In solid-state physics, the work function (sometimes spelled workfunction) is the minimum thermodynamic work (i.e., energy) needed to remove an electron from a solid to a point in the vacuum immediately outside the solid surface. Here "immediately" means that the final electron position is far from the surface on the atomic scale, but still too ...
The significance of work experience as a predictor of job performance is debatable [18] as experience correlates with performance for people with 0–3 years’ experience, but the correlation is attenuating to just 0.15 at 12+ years of experience. This suggests that experience doesn't increase performance after any more than a few years ...
