Introduction to force01:25

Introduction to force

1.6K
Consider water flowing from a nozzle to a turbine vane. As the water hits the turbine vane, it exerts a force that causes it to move along the flow of direction. Force is an impact that changes an object's motion, shape, or orientation. Forces can be caused by physical contact, such as a push or pull, or through non-contact interactions, such as magnetic or gravitational forces. Force is a vector quantity with both magnitude and direction, and is measured in newtons (N) in the SI unit...

Critical Thinking I01:24

Critical Thinking I

5.3K
Critical thinking helps decision-making and allows nurses to recognize barriers to success and find solutions to possible issues. It helps to brainstorm and implement ideas to achieve goals. Critical thinking helps acknowledge and state workflow inefficiencies while improving management techniques. Nurses understand the value of critical thinking and look for fellow nurses with critical thinking skills to upgrade their professional standards. Critical thinking can advance a nurse's career...

Introduction to Test of Independence01:21

Introduction to Test of Independence

2.2K
In statistics, the term independence means that one can directly obtain the probability of any event involving both variables by multiplying their individual probabilities. Tests of independence are chi-square tests involving the use of a contingency table of observed (data) values.
The test statistic for a test of independence is similar to that of a goodness-of-fit test:

Surveys02:16

Surveys

14.4K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Significance Testing: Overview01:04

Significance Testing: Overview

10.2K
Significance testing is a set of statistical methods used to test whether a claim about a parameter is valid. In analytical chemistry, significance testing is used primarily to determine whether the difference between two values comes from determinate or random errors. The effect of a particular change in the measurement protocol, analyst, or sample itself can cause a deviation from the expected result. In the case of a suspected deviation/outlier, we need to be able to confirm mathematically...

Kirchoff's Rules: Application01:22

Kirchoff's Rules: Application

2.2K
Kirchhoff's rules quantify the current flowing through a circuit and the voltage variations around the loop in a circuit. Applying Kirchhoff's rules generates a set of linear equations that allow us to find the unknown values in circuits. These may be currents, voltages, or resistances.
When applying Kirchhoff's first rule, the junction rule, label the current in each branch and decide its direction. If the chosen direction is wrong, it will have the correct magnitude, although the...

Area of Science:

  • Orthopedic surgery
  • Biomedical engineering

Context:

  • Unicompartmental knee arthroplasty remains a controversial topic in orthopedics.
  • Significant advancements in surgical techniques and patient selection have occurred since 1980.

Purpose:

  • To address 1994 questions regarding indications, techniques, and outcomes of unicompartmental knee prostheses.
  • To provide guidance for surgeons in selecting appropriate cases and optimizing prosthetic technology.

Summary:

  • Outcomes of unicompartmental knee arthroplasty series before 1980 are not comparable to later series due to improved methods.
  • Reported failure rates vary widely (6-25%) due to difficulties in result evaluation and lack of standardized scoring.
  • Implementing standardized evaluation systems and survival curves is recommended for future comparable results.

Impact:

  • Aims to improve surgeon selection of indications and prosthetic technology for better unicompartmental knee arthroplasty outcomes.
  • Standardized evaluation will facilitate more accurate comparisons of long-term success rates in knee arthroplasty procedures.
