Area of Science:

  • Biomedical Engineering
  • Immunology
  • Analytical Chemistry

Background:

  • Immunophenotyping is a cell-based solid-phase immunoassay commonly performed using flow cytometry.
  • Existing methods analyze immunologic reactions on the surface of leukocytes.

Purpose of the Study:

  • To introduce a novel flow cytometric application utilizing suspension array technology.
  • To highlight the shift from cell-surface to bead-surface immunologic reactions.

Main Methods:

  • Development of a multiplexed solid-phase assay using plastic fluorospheres.
  • Application of flow cytometry principles to the suspension array technology.

Main Results:

Cable Subjected to a Distributed Load01:24

Cable Subjected to a Distributed Load

The analysis of suspension bridges is a complex and critical process that involves multiple factors, including the shape and tension of the main cables. The main cables of suspension bridges are subjected to distributed loads, which result in changes in tensile forces and deformation of the cable. These loads must be carefully considered to ensure that the bridge is safe and capable of supporting the weight of different loads.
Applications of Stress01:04

Applications of Stress

Consider a structure made of a boom and a rod designed to support a load. These two components are connected by a pin and stabilized by brackets and pins. The boom and the rod are detached from their supports to assess the different stresses imposed on this structure, and a free-body diagram is drawn. Then, all the forces applied, including the load acting on the structure, are identified. The reaction forces exerted on both the boom and the rod are computed using the equilibrium equations.

Method of Superposition01:20

Method of Superposition

The method of superposition is a crucial technique in structural engineering, used to analyze the effect of multiple loads on beams. This approach involves calculating the deflection and slope for each load on a beam separately, and then summing these effects to determine the overall impact. It is applicable only when the beam material remains within its elastic limit, ensuring that deformations are linearly elastic.
When applying the method of superposition, each type of load—whether...
