Heating and Cooling Curves02:44

Heating and Cooling Curves

27.6K
When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

Plasticizers01:31

Plasticizers

362
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

Plasticity

3.1K
Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...

Acid-Base Titration Curves02:23

Acid-Base Titration Curves

141.0K
A titration curve is a plot of some solution property versus the amount of added titrant. For acid-base titrations, solution pH is a useful property to monitor because it varies predictably with the solution composition and, therefore, may be used to monitor the titration’s progress and detect its endpoint. Acid-base titration can be performed with a strong acid and a strong base, a strong acid and a weak base, or a strong base and a weak acid.
For a titration carried out for 25.00 mL of...

Plastic Behavior01:21

Plastic Behavior

560
A material's elastic behavior is characterized by the disappearance of stress once the load is removed, allowing the material to return to its original state. However, when stress surpasses the yield point, yielding commences, marking the onset of plastic deformation or permanent set. This change from elastic to plastic behavior is influenced by the peak stress value and the duration before the load is removed. An intriguing observation occurs when a specimen is loaded, unloaded, and...

Area of Science:

  • Ecology
  • Evolutionary Biology
  • Physiology

Background:

  • Thermal performance curves (TPCs) are crucial for understanding ectotherm responses to temperature.
  • Predicting climate change impacts on organisms relies heavily on TPCs.
  • Environmental conditions can influence TPC shape and parameters.

Purpose of the Study:

  • To investigate how ontogenetic and transgenerational thermal environments affect TPC shape in *Drosophila melanogaster*.
  • To determine the influence of thermal variability and constant high temperatures on fruit fly locomotor performance TPCs.

Main Methods:

  • *Drosophila melanogaster* were reared under constant (28°C, 30°C) and variable (28°C ± 4°C) thermal conditions.
  • Locomotor climbing speed was measured to assess performance across a range of temperatures.
  • Ontogenetic and transgenerational effects of thermal environments on TPCs were evaluated.

Main Results:

  • Environmental thermal variability and high constant temperatures during ontogeny shaped TPC sensitivity.
  • Flies reared in variable thermal environments exhibited right-shifted TPCs and increased heat tolerance.
  • Transgenerational effects were observed, with parental thermal history influencing offspring TPC parameters and heat tolerance.

Conclusions:

  • TPC parameters are not fixed and can be modified by early-life and parental thermal environments.
  • Thermal variability can enhance heat tolerance and shift optimal performance temperatures.
  • Caution is advised when using TPCs to predict climate change impacts due to their plasticity.
