Primary and Secondary Growth in Roots and Shoots

Primary and Secondary Growth in Roots and Shoots

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 Square

Root Mean Square

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...

Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Properties of the Root Locus

Properties of the Root Locus

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...

Root-Locus Method

Root-Locus Method

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 Locus

Construction of Root Locus

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...

Area of Science:

Endodontics
Dental Materials Science

Background:

Internal root resorption poses a challenge in endodontic treatment.
Calcium silicate-based cements (CSCs) are used for vital pulp therapies and root repair.

Purpose of the Study:

To evaluate the fracture resistance of teeth with simulated internal root resorption cavities filled with different CSCs.
To compare the efficacy of ProRoot MTA, Biodentine, NeoMTA 2, and BioMTA+ in restoring tooth strength.

Main Methods:

Seventy-two human central incisors were prepared with standardized root length.
Simulated internal root resorption cavities were created and filled with four different CSCs or left empty (negative control).
A positive control group with intact roots was included. Fracture resistance was tested using a universal testing machine with 135° angle loading.

Main Results:

The Biodentine group exhibited significantly higher fracture resistance compared to the negative control group.
Fracture resistance varied among the tested CSCs, with Biodentine showing promising results.
The study provides quantitative data on the mechanical performance of teeth restored with CSCs after simulated resorption.

Conclusions:

Biodentine demonstrated a potential to enhance the fracture resistance of teeth with internal root resorption cavities.
The findings suggest that Biodentine may contribute to maintaining tooth structure integrity.
Further research could explore long-term clinical outcomes and the biomechanical behavior of other CSCs.
