Computers in Schools in the USA: A Social History,This chapter looks at the history of computers in the USA schools from a social history perspective. Instead of concentrating on innovations and leaders the story of mass adoption in schools is told. This history focuses on the 1980s when the major growth of student numbers and hours of contact with computers became a reality in American schools.

Optical Soliton Propagation in Erbium Doped Nonlinear Fiber MediaAfter the invention of laser, the practical applications of nonlinear optical effects are utilized in many fields. Out of those, one in optical fiber is the most important one. That is the optical solitons, which is useful in optical communication and pulse compression.

Kotarbiński: Logic, Semantics and OntologycGMP are (i) phosphodiesterases, resulting in interference with the cAMP-signalling pathway, (ii) cGMP-gated cation channels, and (iii) cGMP-dependent protein kinases (cGKs). Only two mammalian isotypes of cGK have been described so far: type I cGK, consisting of an a and a β isoform, presumably spl

The effects of surface conductance graded materials (.-SFGM) and bulk permittivity graded materials (.-FGM) on the electric field distributions along the basin-type spacer are investigated under DC stationary and transient conditions. Results show that the .-SFG
