Reliability and Validity01:29

Reliability and Validity

14.1K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Conjugate Addition (1,4-Addition) vs Direct Addition (1,2-Addition)

4.4K
α,β-Unsaturated carbonyl compounds with two electrophilic sites, the carbonyl carbon, and the β carbon, are susceptible to nucleophilic attack via two modes: conjugate or 1,4-addition and direct or 1,2-addition.
Conjugate addition results in a thermodynamically stable product. The reaction retains the stronger C=O bond at the expense of the weaker C=C π bond. The process is slow as the β carbon is less electrophilic than the carbonyl carbon.
Direct addition products are...

Additional Subnuclear Structures

5.4K
The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals. 
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles,...

Steel Manufacturing01:26

Steel Manufacturing

1.5K
Steel manufacturing is a multi-stage process that begins by smelting iron ore into cast iron in a blast furnace. This initial stage involves layering iron ore with coke, a type of fuel, and crushed limestone within the furnace. The coke is ignited with a high volume of air, leading to the creation of carbon monoxide, which acts to reduce the iron ore to pure iron.
During this smelting process, limestone plays a crucial role by forming slag. Slag captures impurities within the molten iron, such...

Conjugate Addition of Enolates: Michael Addition

3.6K
The attack of a nucleophile at the β carbon of an α,β-unsaturated carbonyl compound is called conjugate addition. Conjugate addition reactions of active methylene compounds, such as β-diketones, β-keto esters, β-keto nitriles, and α-nitro ketones, are called Michael addition reactions.

Components of Stress01:23

Components of Stress

550
Stress analysis under multiple loading conditions is intricate, necessitating a comprehensive grasp of normal and shearing stresses. Consider a small cube at point O, subjected to stress on all six faces, visible or not. Normal stress components σx, σy, σz act perpendicularly to the x, y, and z axes. Shearing stress components τxy and τxz are exerted on faces perpendicular to these axes.
Interestingly, the hidden cube faces also experience these stresses, equal and...

Summary

Additively manufactured implants offer a cost-effective alternative for validating radiographic imaging of joint replacements. While minor differences exist compared to conventional implants, they are not clinically significant for imaging technique validation.

Area of Science:

  • Orthopedic surgery
  • Medical imaging
  • Additive manufacturing

Background:

  • Radiographic imaging is standard for evaluating joint replacements post-surgery.
  • Validating imaging techniques requires phantoms or cadavers with implants.
  • Conventionally manufactured implants are often inaccessible and expensive.

Purpose of the Study:

  • To assess additively manufactured implants as a cheaper alternative for radiographic imaging validation.
  • To compare bias and repeatability of additively manufactured vs. conventionally manufactured implants.
  • To determine if additively manufactured implants are suitable for imaging validation studies.

Main Methods:

  • A phantom study using model-based radiostereometric analysis was conducted.
  • Bias and repeatability were measured for both implant types.
  • Measurements compared implant models to bone beads and between implant components.

Main Results:

  • Additively manufactured implants showed less bias in internal-external rotation but more in other axes.
  • Repeatability was better for internal-external rotation but worse for medial-lateral translation and abduction-adduction rotation.
  • Observed differences were small (0.01 mm, 0.5°) and within measurement error.

Conclusions:

  • Additively manufactured implants are a viable, cost-effective substitute for conventional implants in radiographic imaging validation.
  • Fabrication must adhere to manufacturer specifications for reliable results.
  • The observed differences are not clinically significant for validating imaging techniques.
