Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Cold Weather Concreting

Cold Weather Concreting

When freshly poured concrete is exposed to freezing temperatures before it has set, the water within the concrete can freeze. This expansion disrupts the setting process, delays chemical reactions necessary for hardening, and increases the volume of pores within the hardened concrete, which weakens its overall structure. If the concrete manages to reach an appreciable strength before it freezes, the damage can be somewhat mitigated.
To counteract the negative impacts of cold weather, ensuring...

Masonry in Cold and Hot Weather Conditions

Masonry in Cold and Hot Weather Conditions

In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.
Other key practices include keeping masonry units...

Factorial Design

Factorial Design

Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...

Kinetic Molecular Theory: Molecular Velocities, Temperature, and Kinetic Energy

The kinetic molecular theory qualitatively explains the behaviors described by the various gas laws. The postulates of this theory may be applied in a more quantitative fashion to derive these individual laws.

Summary

This summary is machine-generated.

The Ponseti method for idiopathic clubfeet uses plaster casts, causing temperature fluctuations. A significant temperature drop after casting may cause patient discomfort, potentially due to water evaporation.

Area of Science:

Orthopedics
Biomedical Engineering

Background:

Idiopathic clubfoot is commonly treated with the Ponseti method involving serial manipulation and casting.
Plaster of Paris casting material undergoes exothermic and endothermic reactions, leading to temperature changes.
These temperature variations can cause patient discomfort during treatment.

Purpose of the Study:

To investigate the thermal profile of below-cast temperatures during the Ponseti method.
To identify the causes of patient discomfort associated with casting.

Main Methods:

Utilized a digital thermometer with a data logger to measure temperatures beneath the cast.
Monitored temperature changes in 10 patients undergoing clubfoot treatment.

Main Results:

Observed an initial temperature peak followed by a significant temperature decrease (Tmin = 26°C).
This notable temperature dip persisted for approximately 12 hours post-casting.

Conclusions:

Evaporation of excess water from the plaster cast is a potential cause of discomfort.
Understanding cast thermal dynamics can improve patient and caregiver experience in clubfoot treatment.
