Assessing Body Temperature - Axilla01:14

Assessing Body Temperature - Axilla

661
Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

Energy Carried By Electromagnetic Waves

3.2K
Anyone who has used a microwave oven knows there is energy in electromagnetic waves. Sometimes, this energy is obvious, such as in the summer sun's warmth. At other times, it is subtle, such as the unfelt energy of gamma rays, which can destroy living cells. Electromagnetic waves bring energy into a system through their electric and magnetic fields. These fields can exert forces and move charges in the system and, thus, do work on them. However, there is energy in an electromagnetic wave,...

In the domain of radio communication, the significance of impedance matching must be considered. It is crucial to ensure the efficient transmission of signals between radio transmitters and receivers. Achieving this balance involves using impedance-matching circuits, with one fundamental configuration comprising a resistor, capacitor, and inductor.
The process of harmonizing these impedances begins with a clear understanding of the input and output signals. Once these signals are known, the...

Area of Science:

  • Biomedical Engineering
  • Nanotechnology
  • Communication Systems

Background:

  • Molecular communication (MC) is a promising paradigm for wireless body area nanonetworks (WBANs).
  • MC utilizes molecules as information carriers between nanomachines.
  • Residual molecules in the communication medium can impact nano-transmitter performance.

Purpose of the Study:

  • To develop an electrical model for molecular-based nano-transmitters.
  • To analyze the influence of residual molecules on nano-transmitter energy consumption.
  • To propose a method for enhancing energy efficiency and investigate the energy-delay trade-off.

Main Methods:

  • An advection-diffusion equation with a non-zero initial condition was used to model residual molecules.
  • An electrical model was derived to analyze energy consumption in the presence of residual molecules.
  • The settle-time method, incorporating interruption periods and a control coefficient, was proposed and evaluated.

Main Results:

  • Residual molecules negatively impact nano-transmitter energy consumption.
  • The proposed settle-time method significantly enhances energy efficiency.
  • Simulations with insulin molecules showed a 15% reduction in energy consumption with a 2.2 ms latency increase for a 1 ms interruption period.

Conclusions:

  • The electrical model effectively analyzes residual molecule effects in MC.
  • The settle-time method offers a viable solution for energy efficiency in WBANs.
  • Optimizing interruption periods balances energy consumption and communication delay.
