Primary and Secondary Growth in Roots and Shoots03:02

Primary and Secondary Growth in Roots and Shoots

60.3K
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Root Mean Square00:57

Root Mean Square

3.7K
If in an experiment, data values have a probability of being both positive and negative, neither the arithmetic mean, the geometric mean, nor the harmonic mean can be used to calculate the central tendency of the data set. In particular, if the positive and negative values are equally likely, the arithmetic mean is close to zero.
For example, consider the velocity of gas molecules in a container. The gas molecules are moving in different directions, which might impart positive and negative...

Root-Locus Method01:19

Root-Locus Method

492
A cruise control system in a car is designed to maintain a specified speed automatically by adjusting the gas pedal. The system continuously measures the vehicle's speed and makes fine adjustments to the pedal to achieve this goal. The root locus method is particularly useful for understanding how the cruise control system's behavior changes under varying conditions, such as when the car goes uphill, downhill, or faces strong wind resistance.
This system can be represented by a block...

Construction of Root Locus01:15

Construction of Root Locus

406
The construction of a root locus involves several key steps to analyze and visualize the behavior of a system's poles with varying gain. The number of branches in the root locus equals the number of closed-loop poles and is symmetrical about the real axis.
For positive gain values, the root locus exists on the real axis to the left of an odd number of finite open-loop poles or zeros. The root locus starts at the open-loop poles and traces the paths of the closed-loop poles as the gain...

Properties of the Root Locus01:05

Properties of the Root Locus

295
The root locus method is an invaluable tool for analyzing higher-order systems without needing to factor the denominator of the transfer function. A pole of the system is identified when the characteristic polynomial in the transfer function's denominator equals zero.
To determine if a point lies on the root locus, the criterion involves the sum of angles contributed by all poles and zeros to that point. Specifically, this sum must be an odd multiple of 180 degrees. The gain at any point on...

Plotting and Calibrating the Root Locus01:19

Plotting and Calibrating the Root Locus

453
Root loci often diverge as system poles shift from the real axis to the complex plane. Key points in this transition are the breakaway and break-in points, indicating where the root locus leaves and reenters the real axis. The branches of the root locus form an angle of 180/n degrees with the real axis, where n is the number of branches at a breakaway or break-in point.
The maximum gain occurs at the breakaway points between open-loop poles on the real axis, while the minimum gain is...

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Knee Biomechanics

Background:

  • Meniscus root tears account for 10-21% of meniscal injuries, impacting nearly 100,000 individuals yearly.
  • These tears disrupt meniscal function, impairing load distribution and leading to posterior knee pain and joint line tenderness.
  • Magnetic resonance imaging (MRI) reveals specific signs like meniscal extrusion and the 'ghost sign' for diagnosis.

Purpose of the Study:

  • To review the diagnosis, indications for repair, and surgical techniques for meniscus root tears.
  • To highlight the biomechanical consequences of root tears and the benefits of repair over meniscectomy.
  • To emphasize early referral and surgical consideration for active patients with meniscus root tears.

Main Methods:

  • Review of biomechanical studies and clinical outcomes related to meniscus root tears.
  • Analysis of diagnostic criteria using magnetic resonance imaging (MRI).
  • Evaluation of indications and surgical techniques, primarily transosseous meniscal root repair.

Main Results:

  • Meniscus root tears lead to the failure of load conversion, causing significant knee pain and dysfunction.
  • Meniscal root repair demonstrates high satisfaction rates and superior outcomes compared to arthroscopic meniscectomy.
  • Transosseous repair technique allows for secure fixation and maximizes healing potential.

Conclusions:

  • Early consideration for meniscus root repair is crucial for active patients, regardless of age.
  • Meniscal root repair effectively restores meniscus function and provides better long-term outcomes than meniscectomy.
  • The transosseous technique offers advantages in healing potential and functional restoration.
