Design Example: Creating a Hydraulic Model of a Dam Spillway

749
Scaled hydraulic models of dam spillways provide a practical way to replicate and study the intricate flow dynamics of these structures. Often built to a 1:15 ratio, these models allow for observing critical water behavior, such as velocity distribution, flow patterns, and energy dissipation.

Experimental Determination of Chemical Formula

47.6K
The elemental makeup of a compound defines its chemical identity, and chemical formulas are the most concise way of representing this elemental makeup. When a compound’s formula is unknown, measuring the mass of its constituent elements is often the first step in determining the formula experimentally.

Nucleic acids

190.6K
Nucleic acids are the most important macromolecules for the continuity of life. They carry the cell's genetic blueprint and carry instructions for its functioning.
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...

In- and Out-Groups

People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Area of Science:

  • Hand Surgery
  • Reconstructive Surgery
  • Pediatric Orthopedics

Background:

  • Thumb hypoplasia necessitates reconstructive surgery.
  • Traditional pollicisation techniques can lead to complications like a
  • pseudo-trapezium
  • and elongated thumbs.

Purpose of the Study:

  • To evaluate a modified pollicisation technique that omits the creation of a
  • pseudo-trapezium
  • .

Main Methods:

  • Performed 14 pollicisations by excising the entire metacarpal of the donor digit.
  • Inserted the proximal phalanx into the metacarpal base space.
  • Did not create a
  • pseudo-trapezium
  • .

Main Results:

  • Good to excellent outcomes in all 14 cases.
  • Follow-up ranged from 2 to 9 years.
  • The reconstructed thumbs were more aesthetically pleasing and stable.

Conclusions:

  • This simplified pollicisation technique offers a quicker and safer alternative.
  • Avoids complications associated with the
  • pseudo-trapezium
  • .
  • Results in a more stable, thumb-like reconstruction.
