2011
The methodology for fabricating synthetic vocal fold models is described. The models are life-sized and mimic the multi-layer structure of the human vocal folds. Results show the models to self-oscillate at pressures comparable to lung pressure and demonstrate flow-induced vibratory responses that are similar to those of human vocal folds.

To cultivate neural crest stem cells (NCSC) in vitro, a special medium (NCSCM) is required. Essential part of NCSCM is chick embryo extract (CEE). We here describe accurate techniques to produce a maximized amount of pure and high quality CEE, including details as the isolation, maceration, centrifugation, and filtration processes.

Source: Michael G. Benton and Kerry M. Dooley, Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA The Spin-and-Chill uses heat transfer and fluid flow fundamentals to chill beverages from room temperature to 38 °F in as little as 2 min. It would take a refrigerator approximately 240 min and an ice chest approximately 40 min to achieve an equivalent temperature change. This is accomplished Spin and Chill by spinning a can or bottle at up to 500 rpm, which creates...

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Concrete and asphalt are by far the most common construction materials used today. Concrete is a composite material consisting of cement, water, air, coarse aggregate, and fine aggregates. Fine aggregates are typically sands and coarse aggregates are natural or crushed rocks. Chemical admixtures to modify certain specific properties are also commonly used (i.e., superplasticizers to make the...

Robert M. Rioux, Pennsylvania State University, University Park, PA The Occupational Safety and Health Administration (OSHA) mandates that an emergency eyewash and shower station be easily accessible in all workplaces in which a person could be exposed to injurious and/or corrosive substances. Emergency eyewash and shower stations should be used in the case of a laboratory or workplace accident that involves the spilling of a harmful, possibly corrosive chemical onto the body or the splashing...

The conversion formula combines two mathematical features: a scale factor and a fixed offset. Multiplying Celsius by 9/5 adjusts the size of its intervals to Fahrenheit intervals, while adding 32 aligns the numerical starting points. This linear structure lets a Celsius measurement be translated consistently, rather than treated as an unrelated temperature value.
To convert Fahrenheit to Celsius, first subtract 32 and then multiply by 5/9: °C = (°F − 32) × 5/9. Subtraction removes the Fahrenheit offset, and multiplication reverses the 9/5 scale factor. Applying the operations in this order preserves the correspondence between the two numerical representations.
Temperature changes can have different numerical sizes on the two scales. Because the conversion uses a 9/5 factor, a one-degree Celsius change corresponds to a 9/5-degree Fahrenheit change, while the additive 32 does not affect differences. This distinction matters when comparing increases, decreases, or experimental changes rather than single readings.
Standard atmospheric pressure provides the reference condition for the water-based benchmark points used in these scales. If a problem or experiment cites freezing or boiling values, noting that condition keeps the comparison mathematically consistent with the stated 0°C, 100°C, 32°F, and 212°F landmarks. It prevents the reference from being treated as condition-free.
To convert a Celsius reading in a worksheet, multiply the value by 9/5, then add 32, and label the result in degrees Fahrenheit. Keeping the arithmetic steps separate reduces sign and order errors. The same workflow supports weather records, medical temperature communication, and experimental data when values need to be reported in Fahrenheit.
Choose the scale that matches the audience or reporting convention, then convert when comparison requires a common format. Celsius may appear in scientific or international data, whereas Fahrenheit may be expected in other everyday or weather contexts. The conversion allows measurements from different countries or sources to be compared without changing the underlying temperature.
Mathematics makes the scales interoperable through a linear relationship, so students can check whether a converted value is reasonable by using the paired reference points and the formula. This is useful when interpreting experimental results, comparing weather reports, or communicating medical measurements, because the numerical scale changes while the temperature being described remains the same.
