Areas Within Irregular Boundaries01:26

Areas Within Irregular Boundaries

348
Calculating areas within irregular boundaries, such as along rivers or curved roads, is crucial in various fields, including surveying, engineering, and environmental management. Surveyors often begin by creating a traverse, a connected series of straight lines approximating the area's boundary. The coordinates of each traverse point are essential for calculating the enclosed area. The double meridian distance formula is a widely used technique for this purpose. This method utilizes the...

Electrostatic Boundary Conditions01:16

Electrostatic Boundary Conditions

942
Consider an external electric field propagating through a homogeneous medium. When the electric field crosses the surface boundary of the medium, it undergoes a discontinuity. The electric field can be resolved into normal and tangential components. The amount by which the field changes at any boundary is given by the difference between the field components above and below the surface boundary.
The surface integral of an electric field is given by Gauss's law in integral form and is related to...

Magnetostatic Boundary Conditions

1.6K
An electric field suffers a discontinuity at a surface charge. Similarly, a magnetic field is discontinuous at a surface current. The perpendicular component of a magnetic field is continuous across the interface of two magnetic mediums. In contrast, its parallel component, perpendicular to the current, is discontinuous by the amount equal to the product of the vacuum permeability and the surface current. Like the scalar potential in electrostatics, the vector potential is also continuous...

Boundary Layer Characteristics01:18

Boundary Layer Characteristics

596
When a fluid encounters a solid surface, a boundary layer forms due to the interaction between the fluid's motion and the stationary surface. This phenomenon is characterized by a thin region adjacent to the surface where viscous forces dominate, influencing the fluid's velocity profile. The development of the boundary layer begins at the leading edge of the surface and evolves as the fluid moves downstream.As the fluid flows over the surface, friction between the fluid and the wall slows down...

Boundary Conditions: Lossless Lines01:21

Boundary Conditions: Lossless Lines

433
Consider a single-phase, two-wire, lossless transmission line terminated by an impedance at the receiving end and a source with Thevenin voltage and impedance at the sending end. The line, with length, has a surge impedance and wave velocity determined by the line's inductance and capacitance.
At the receiving end, the boundary condition states that the voltage equals the product of the receiving-end impedance and current. This relationship is expressed as a function of the incident and...

Boundary Conditions for Current Density

1.3K
Current density becomes discontinuous across an interface of materials with different electrical conductivities. The normal component of the current density is continuous across the boundary.

Area of Science:

  • Medical Ethics
  • Nursing Practice
  • Digital Health

Background:

  • The personal use of social media by healthcare professionals presents challenges to maintaining professional boundaries in oncology.
  • Online access to personal information of providers by patients and families can blur the lines between personal and professional life.

Purpose of the Study:

  • To examine the responsibility of oncology nurses in maintaining professional boundaries in the context of social media.
  • To assess the potential risks to professional image associated with patients and families accessing providers' personal online information.
  • To present work from the Advanced Practice Nursing Social Media Taskforce, including a literature review and staff survey.

Main Methods:

  • Literature review on social media use and professional boundaries in healthcare.
  • Development and administration of a staff survey to explore perceptions and practices regarding personal social media use.
  • Analysis of case scenarios illustrating common social media challenges.

Main Results:

  • Exploration of perceptions and practices related to personal social media use among health professionals.
  • Identification of common challenges and risks associated with social media use in oncology settings.

Conclusions:

  • Oncology nurses have a critical responsibility to uphold professional boundaries online.
  • Strategies for knowledge translation and managing social media challenges are essential for protecting professional image.
