Habitat Fragmentation02:31

Habitat Fragmentation

21.2K
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

Faraday Disk Dynamo01:23

Faraday Disk Dynamo

3.6K
A Faraday disk dynamo is a DC generator, producing an emf that is constant in time. It consists of a conducting disk that rotates with a constant angular velocity in the magnetic field, perpendicular to the disk's plane. The rotation of the disk causes a change in magnetic flux, which induces an emf, causing opposite charges to develop on the rim and in the center of the disk. The polarity of the induced emf can be determined by the direction of the magnetic field and the direction of the...

Fischer Projections

16.4K
Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A Fischer projection is a two-dimensional projection on a planar surface to simplify the three-dimensional wedge–dash representation of molecules. This is especially helpful in the case of molecules with multiple chiral centers that can be difficult to draw. Here, all the bonds of interest are represented as horizontal or vertical lines. While...

Newman Projections

20.7K
Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as...

Electric Field of a Charged Disk01:23

Electric Field of a Charged Disk

3.1K
The simplest case of a surface charge distribution is the uniformly charged disk. Calculating its electric field also helps us calculate the electric field of a large plane of charge.
The system's symmetry is in the cylindrical directions across the plane of the charge. As a result, the electric fields created by various surface charge elements nullify each other in the direction parallel to the surface. Thereby, the resulting electric field is perpendicular to the plane. Since the disk is...

Area of Science:

  • Plastic Surgery
  • Reconstructive Surgery
  • Biomaterials in Medicine

Background:

  • Nipple reconstruction is a critical final step in breast reconstruction.
  • Reduced nipple projection post-surgery often leads to patient dissatisfaction.
  • Investigating methods to improve long-term nipple projection is crucial.

Purpose of the Study:

  • To evaluate the effectiveness of a novel nipple reconstruction method using acellular dermal matrix (ADM).
  • To compare nipple projection and diameter outcomes with a control group not using ADM.
  • To analyze the correlation between nipple dimensions and reconstruction methods.

Main Methods:

  • A modified C-V flap technique was employed with ADM disk fixation.
  • ADM fragments were used to create a column for projection support.
  • Nipple diameter and projection were measured at 1-year follow-up and compared to a control group.

Main Results:

  • The ADM group showed significantly smaller diameter (p=0.00) and higher projection (p=0.00) at 1 year compared to controls.
  • A significant correlation between nipple diameter and projection was observed (p=0.00).
  • Latissimus dorsi flap plus implant yielded the highest projection, followed by expander and TRAM flap groups.

Conclusions:

  • Nipple reconstruction with ADM disk and fragments effectively maintains nipple projection.
  • This technique prevents downward tissue shift and footprint broadening.
  • ADM offers a favorable solution for long-term nipple projection maintenance in breast reconstruction.
