Source: Ricardo Mejia-Alvarez and Hussam Hikmat Jabbar, Department of Mechanical Engineering, Michigan State University, East Lansing, MI Hot-wire anemometers have a very short time-response, which makes them ideal to measure rapidly fluctuating phenomena such as turbulent flows. The purpose of this experiment is to demonstrate the use of hot-wire anemometry.

An automated myography method for force measurements in isolated mesenteric arteries is described. It employs a Mulvany-Halpern Auto Dual Wire Myograph 510A to determine responses to phenylephrine and extracellular calcium. The method allows consistent determination of isometric responses to agonists in small vessels of diameters of 60 - 300 μm, independently.

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

An infinite series composed of positive terms may either approach a finite value or increase without bound. Determining which outcome occurs is a central task in calculus, and comparison tests provide structured methods for making this determination. Rather than evaluating a series directly, these tests relate it to another series whose behavior is already known, allowing conclusions to be drawn through logical comparison.The direct comparison test applies to series with positive terms. If each...

Extracellular Wire Tetrode Recording in Brain of Freely Walking Insects

We previously developed a technique for implanting tetrode wires into the central complex of cockroach brains that allows us to monitor activity in individual units of tethered cockroaches. Here we present a modified version of that technique that allows us to also record brain activity in freely moving insects.

Resistance reflects both the conductor’s length and its cross-sectional area, so increasing size does not eliminate the effect of a long run. For conductors made from the same material, a larger area reduces resistance, while greater length increases it. Engineers therefore compare wire sizes in relation to the actual run length to limit voltage drop, heating, and energy loss.
Diameter provides a physical measurement of the conductor, while gauge provides another way to identify wire size. Cross-sectional area is especially useful when the comparison must relate size to resistance and current capability; diameter is useful when checking physical space. Using the same size basis throughout a design helps prevent misleading comparisons between conductors.
Conductor size alone does not determine allowable current. Insulation and installation conditions affect the temperature a wire can tolerate and the way heat is managed during operation. Consequently, a conductor that appears electrically suitable may require reconsideration when its insulation, surrounding conditions, or installation arrangement changes. These factors are essential when evaluating ampacity and overheating risk.
Begin by identifying the design’s electrical requirements, then compare candidate conductors by cross-sectional area, diameter, or gauge. Evaluate resistance-related voltage drop and heat generation, followed by allowable current under the relevant insulation and installation conditions. Finally, check physical space, flexibility, and cost so the selected conductor satisfies performance and installation needs together.
A larger conductor can improve current handling and reduce voltage drop and heat generation, but it may occupy more space, provide less flexibility, or increase cost. Wire size comparison therefore supports a balanced selection rather than choosing the largest available conductor automatically. The appropriate option is the one that meets electrical and temperature requirements within the design’s physical and economic constraints.
The comparison supports conductor selection in power distribution, control systems, electronics, and building wiring. The relevant priorities can differ among these settings, including current capability, voltage drop, physical fit, flexibility, and cost. Applying the comparison to the intended system helps engineers choose conductors that support reliable operation and reduce the likelihood of overheating, energy loss, or premature equipment failure.
