Stress-Strain Diagram - Brittle Materials01:24

Stress-Strain Diagram - Brittle Materials

Brittle materials, including glass, cast iron, and stone, exhibit unique characteristics. They fracture without considerable change in their elongation rate, indicating that their breaking and ultimate strength are equivalent. Such materials also show lower strain levels at the point of rupture. The failure in brittle materials predominantly results from normal stresses, as evidenced by the rupture created along a surface perpendicular to the applied load. These materials do not display...
Fixing Double-strand Breaks02:04

Fixing Double-strand Breaks

The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...

Microcracking in Concrete01:20

Microcracking in Concrete

Microcracking in concrete refers to the tiny cracks that can form within the material even before any external load is applied. These microcracks typically occur at the interface between the coarse aggregate and the hydrated cement paste, often as a result of differential volume changes prompted by variations in stress-strain behavior, as well as thermal and moisture movement. Initially, these microcracks remain stable and do not grow substantially until the concrete is stressed to about 30...
Fineness of Cement01:15

Fineness of Cement

The fineness of cement directly influences the rate of hydration, as the hydration begins at the surface of the cement particles. In addition to hydration, the fineness of cement is vital for various properties of concrete including workability, gypsum requirement, and long-term behavior. The fineness of cement is represented in terms of the specific surface of cement which is typically measured in square meters per kilogram, with several methods available for this determination.

Fatigue01:21

Fatigue

Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

Summary
This summary is machine-generated.

Endotines and Ultratines, used for brow elevation, are made of polylactic and polyglycolic acid polymers. Ultratines break more frequently during insertion than Endotines, prompting recommendations to reduce breakage.

  • Plastic Surgery
  • Biomaterials Science

Background:

  • Endotines and Ultratines are surgical devices utilized in brow elevation procedures.
  • Both devices are composed of polylactic acid and polyglycolic acid polymers.

Purpose of the Study:

  • To compare the intraoperative breakage rates of Endotines and Ultratines.
  • To present clinical experience and offer strategies to minimize device breakage during brow elevation.

Main Methods:

  • Retrospective review of brow elevation procedures using Endotines and Ultratines.
  • Analysis of device integrity during loading and insertion phases.

Main Results:

  • Ultratines demonstrated a significantly higher incidence of breakage compared to Endotines.
  • Breakage occurred predominantly during the loading and insertion stages of the procedure.

Conclusions:

  • Endotines exhibit superior intraoperative stability over Ultratines in brow elevation.
  • Implementing specific techniques can mitigate the risk of device fracture, enhancing procedural success.
