Anatomical Terminology01:20

Anatomical Terminology

23.2K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Mortar01:29

Mortar

373
Mortar, a mixture of Portland cement, hydrated lime, sand, and water, is a crucial binding material in construction. Its primary function is to join masonry units together, filling gaps and ensuring a uniform distribution of weight across the structure. This helps in preventing potential weaknesses. Mortar also serves as a protective barrier against environmental elements such as water and wind, thereby safeguarding the interior of the structure. It also compensates for surface irregularities...

Mortar Joint Deterioration in Masonry01:13

Mortar Joint Deterioration in Masonry

187
Mortar joint deterioration is a significant concern in masonry structures, with water accumulation in the joints leading to damage from freeze-thaw cycles. The repeated expansion of water during freezing and its melting during thawing develop and propagate cracks in the masonry joints. Eventually, this leads to the spalling of mortar from the joints, loosening masonry units and weakening the structure. The deteriorated mortar joints are also vulnerable to moisture intrusion into the walls.

Mortar Properties01:17

Mortar Properties

241
Mortar properties encompass a range of characteristics crucial for construction and masonry work, including workability, water retention, bond strength, durability, compressive strength, volume change, and appearance. Workability refers to mortar's ability to be easily applied and manipulated without sagging or falling off surfaces, which is important for efficient masonry unit placement and alignment. Water retention is essential to prevent the mortar from losing moisture too quickly to...

Mortar Joints in Brick Masonry01:25

Mortar Joints in Brick Masonry

228
Mortar joints play a critical role in brick masonry, filling the spaces between brick to bind them together and provide structural integrity and strength. The thickness of these joints is variable, typically ranging from less than one-fourth inch to over half an inch, based on structural needs and specific applications.
The process of joint tooling is implemented as the mortar begins to harden. This technique involves compacting and shaping the mortar to enhance both the appearance and the...

Morton's Letheon: When was the name Letheon chosen?

Summary
This summary is machine-generated.

The name "Letheon" for William T. G. Morton's ether anesthetic was likely chosen in a meeting in late November 1846. This timing is suggested by its absence in earlier public notices and its first appearance in a December 9, 1846, journal advertisement.

Area of Science:

  • Medical History
  • Anesthesiology
  • History of Science

Background:

  • William T. G. Morton, a Boston dentist, commercialized an ether-based anesthetic named "Letheon."
  • Historical accounts by Edward Warren and Nathan P. Rice document the meeting where "Letheon" was chosen.
  • The exact date of this crucial naming meeting remains unconfirmed in existing literature.

Discussion:

  • The earliest known reference to "Letheon" is dated December 9, 1846.
  • Morton's public notices preceding this date do not contain the name "Letheon."
  • This suggests the naming meeting occurred later than previously assumed, likely in late November 1846.

Key Insights:

  • Re-evaluation of historical documents suggests a revised timeline for the "Letheon" naming meeting.
  • The absence of "Letheon" in contemporary advertisements points to a specific period for its christening.
  • This finding refines our understanding of the early commercialization of ether anesthesia.

Outlook:

  • Further archival research may uncover definitive evidence of the meeting's date.
  • Understanding the precise timeline aids in reconstructing the early history of anesthesiology.
  • This analysis highlights the importance of scrutinizing publication and advertisement dates in historical research.
