The term generally refers to elements either comprising the right-of-way (such as ballast, ties, track, bridges, and tunnels) or adjacent to it (line-side structures like signs, mileposts, switches, etc.). Also included within this subject are signaling systems and the classic tell-tales. ...
From his early professional days, John was captivated by the notion that our streets, buildings, and public spaces are more than mere structures—they are vital canvases where history, culture, and innovation converge. He championed the idea that urban design is a dynamic dialogue between aesthet...
Aqueducts and canal viaducts –To bridge large distances, ancient romans built series of supports which were connected with stone arches. These series of arched structures were butt not only in one layer like ordinary bridge, but with several layers that could reach very impressive heights. Deck...
Understanding the endocranial HC types is crucial for neurosurgeons in the differential diagnosis of various intracranial pathologies for the posterior cranial fossa approach. Knowing the anatomical relationships between the adjacent structures and symmetrical organization of the HC according to the types is...
Even by the late 19th-century most equipment was still built primarily with wood except for support structures (frame, trucks, and other necessary structural components) made of early steel. The use of steel gave rise to "heavyweight" cars comprised entirely from metal, hence their name. ...
Headache is defined as pain arising from the head or upper neck of the body. The pain originates from the tissues and structures that surround the skull or the brain because the brain itself has no nerves that give rise to the sensation of pain (pain fibers). The thin layer of tissue ...
When thinking about bridges, everyone’s first thought are structures that facilitate easy passenger and car traffic across bodies of water or unfriendly terrain. However, bridges can be versatile and can support many different types of use. Additionally, some bridges are designed in such way to ...
Natural language processing functions such as TextCases, TextPosition and TextContents allow many different types of content to be identified in text. Some of these types of content are structural or grammatical, while others relate to semantic interpretation. Containing — define containers (e.g. ...
A linear ONdO triplet structure is characteristic of NdO2, in contrast to the linear SmOO2+ quintet structure, which is favored by SmO22+. We investigated the bonding behavior of NdO2 and SmO22+ across diverse geometric structures through state-averaged complete active space self-consistent field...
(OT) is one such example in which an ovary twists or flips on its attachment to other structures, causing decreased blood flow. It is a medical emergency that may result in loss of the ovary. Ovarian torsion may occur in females of any age from infants to the elderly. The condition may...
