Masonry in Cold and Hot Weather Conditions01:21

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 and sand dry and...
Thermal expansion and Thermal stress: Problem Solving01:27

Thermal expansion and Thermal stress: Problem Solving

San Francisco's Golden Gate Bridge is exposed to temperatures ranging from -15 °C to 40 °C. At its coldest, the main span of the bridge is 1275 m long. Assuming that the bridge is made entirely of steel, what is the change in its length between these temperatures?
To solve the problem, first, identify the known and unknown quantities. The initial length (L) of the bridge is 1275 m, the coefficient of linear expansion (α) for steel is 12 x 10-6/°C, and the change in temperature (ΔT) is 55 °C.
Thermal Stress01:09

Thermal Stress

If the temperature of an object is changed while it is prevented from expanding or contracting, the object is subjected to stress. The stress is compressive if the object expands in the absence of constraint and tensile if it contracts. This stress resulting from temperature change is known as thermal stress. It can be quite large and can cause damage. To avoid this stress, engineers may design components so they can expand and contract freely. For instance, on highways, gaps are deliberately...
Thermosensation01:43

Thermosensation

Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...
Solvating Effects02:12

Solvating Effects

An understanding of the solvating effect helps rationalize the relation between solvation and acidity of the compound. In addition, this also explains the relative stability of conjugate bases for compounds with different pKa values. This lesson details, in-depth, the principle of solvating effects. The strength of an acid and the stability of its corresponding conjugate base are determined using pKa values. This observed relationship is a consequence of solvation, which is the interaction...
Principle of Virtual Work: Problem Solving01:13

Principle of Virtual Work: Problem Solving

The principle of virtual work is an essential concept in the field of mechanics and engineering. This is used to solve problems related to the equilibrium of a structure or system. It is based on the assumption that if a system is in equilibrium, the work done by all the forces during a virtual displacement is zero. This principle is applied by considering virtual displacements of the system and the corresponding work done by internal and external forces.
To apply the principle of virtual work,...

Area of Science:

  • Human physiology
  • Cognitive science
  • Environmental health

Background:

  • Cold exposure negatively impacts cognitive function, posing risks in survival scenarios.
  • Impaired navigation due to cold can exacerbate problems in lost-person situations.
  • Understanding cold's effects on spatial cognition is crucial for safety and performance.

Purpose of the Study:

  • To investigate the distinct effects of reduced core body temperature and superficial cooling on virtual navigation performance.
  • To determine if cooling impacts spatial memory and navigational abilities.

Main Methods:

  • Twelve healthy males underwent passive cooling to 36.0°C core temperature via water immersion.
  • Participants completed virtual mazes under three conditions: core cooling, superficial cooling, and thermoneutral control.
  • Superficial cooling involved immersion in cold water targeting lower extremities.

Main Results:

  • No significant differences in maze completion time or error scores were observed across core cooling, superficial cooling, and control conditions.
  • Virtual navigation performance remained consistent despite isolated reductions in core temperature or localized cold sensation.

Conclusions:

  • Neither core nor superficial cooling significantly impaired performance on a virtual navigation task.
  • Navigation appears more resistant to cold-induced cognitive impairment compared to simpler cognitive tasks.
  • Further research is needed on navigation at lower temperatures and in diverse populations.
