Early models feature motherboards and power supplies with the A300 designation.

Basch postulates that the boat “ cannot have been propelled by more than four oarsmen … so it can hardly be other than a fishing boat .” As opposed to other Early Bronze Age ship and boat models, this model was not found in a burial context.

Early providers of voice over IP services offered business models ( and technical solutions ) that mirrored the architecture of the legacy telephone network.

; Acoustic tablets: Early models were described as spark tablets — a small sound generator was mounted in the stylus, and the acoustic signal picked up by two microphones placed near the writing surface.

It may seem strange that a poet should come to full fruition in his seventies, but we have it on Hardy's own authority that `` he was a child till he was sixteen, a youth till he was five-and-twenty, and a young man till he was nearly fifty '' ( Early Life, p. 42 ).

According to the fossil record, Lissamphibia, which includes all modern amphibians and is the only surviving lineage, may have branched off from the extinct groups Temnospondyli and Lepospondyli at some period between the Late Carboniferous and the Early Triassic.

Early Pueblo I Era sites may have housed up to 600 individuals in a few separate but closely spaced settlement clusters.

Skeat “… in at least three cases and probably in all, in the form of codices " and he theorized that this form of notebook was invented in Rome and then “… must have spread rapidly to the Near East …” In his discussion of one of the earliest pagan parchment codices to survive from Oxyrhynchus in Egypt, Eric Turner seems to challenge Skeat ’ s notion when stating “… its mere existence is evidence that this book form had a prehistory ” and that “ early experiments with this book form may well have taken place outside of Egypt .” Early codices of parchment or papyrus appear to have been widely used as personal notebooks, for instance in recording copies of letters sent ( Cicero Fam.

Europe's view of the shape of the Earth in Late Antiquity and the Early Middle Ages may be best expressed by the writings of early Christian scholars:

Early Christianity may be divided into 2 distinct phases: the apostolic period, when the first apostles were alive and led the Church, and the post-apostolic period, when an early episcopal structure developed, and persecution was periodically intense.

Early usages of the phrase " politically correct " have been found in various contexts, which may not relate to the current terminology.

Early objects contain Egyptian cotton, which may indicate that Egyptian and Mediterranean trade provided a conduit for the technique.

Various historians have argued that shamanism also played a role in many of the pre-Christian religions of Europe, and that shamanic elements may have survived in popular culture right through to the Early Modern period.

" Early wood " is used in preference to " spring wood ", as the latter term may not correspond to that time of year in climates where early wood is formed in the early summer ( e. g. Canada ) or in autumn, as in some Mediterranean species.

Early osteoarthritis may occur.

Early in 2001 Lakoff told the American Association for the Advancement of Science ( AAAS ): " Mathematics may or may not be out there in the world, but there's no way that we scientifically could possibly tell.

Early cuticle may not have had pores but did not cover the entire plant surface, so that gas exchange could continue.

With the inclusion of the predecessor and successor cultures — Early Harappan and Late Harappan, respectively — the entire Indus Valley Civilization may be taken to have lasted from the 33rd to the 14th centuries BCE.

Early vitrectomy is especially effective in people with insulin-dependent diabetes, who may be at greater risk of blindness from a hemorrhage into the eye.

In 1992 a number of MPs registered an official complaint about this practice, with some commenting that it " has undoubtedly been retained to deter honourable Members from raising points of order during divisions by making them appear ridiculous and feel acutely embarrassed ".< Ref > Early day motion 1623 In 1998 it was recommended that the opera hat be abandoned, since " although some Members may feel that they look particularly fetching in it, it makes the House of Commons look ridiculous when someone wearing the hat is trying to raise a point of order from a seated position while everyone else is milling around and going to vote.

Early on, trainers began to recognize which breeds produced dogs most appropriate for guide work ; today, Golden Retrievers, Labradors, and German Shepherds are most likely to be chosen by guide dog facilities, although other breeds, such as Yorkshire Terriers, Standard Poodles, Collies, Border Collies, Australian Shepherds, Papillons, Vizslas, Dobermans, Rottweilers, Boxers, and Airedale Terriers, may also be selected.

Early use of the mockumentary format in television comedy may be seen in several sketches from Monty Python's Flying Circus ( 1969 – 1974 ), such as " Hell's Grannies ", " Piranha Brothers ", and " The Funniest Joke in the World ".

When John L. Caskey of the American School of Classical Studies at Athens outlined the results of his excavations at Lerna from 1952 up until 1958, he stated that the hallmarks of Middle Helladic culture ( i. e. Gray Minyan ware and the fast potter's wheel ) may have originated from Early Helladic III.

He suggested that the invaders of Early Helladic II settlements may have been Greeks speaking a prototype of the later Greek language.

These works are generally in the Early Netherlandish style, and were probably executed under his patronage and direction, so that he may be said to have formed a school of the fine arts in sculpture, painting, goldsmith's work and tapestry.
