Bursting Citrus Peel Oil Glands Inspire New Approach for Microjetting Fluids

When was the last time you took a close look at an orange, lime or lemon peel? Outer citrus peels are covered with tiny oil glands or cavities that can explode in an outward direction, often spraying toward you, if bent in an attempt to gain access to the inner fruit. Researchers at the University of Central Florida set out to explore how the material properties during this phenomenon enable the production of these high-speed jets that often go unnoticed or unappreciated, even by avid citrus consumers. They’ll discuss their work at the 70th meeting of the Division of Fluid Dynamics, Nov. 19-21, 2017.

Snoring Sounds Provide Insight for Obstructive Airway Disorders

Often unnoticed by the patient, Obstructive Sleep Apnea results in fragmented sleep patterns causing daytime fatigue and cardiovascular problems. However, the question remains of how to differentiate normal snoring from sleep apnea. Researchers will present their results on the 3-D modeling of uvula vibrational patterns and sound frequencies during snoring at the 70th meeting of the Division of Fluid Dynamics, Nov. 19-21, 2017.

Save the Date: Acoustical Society of America Fall Meeting in New Orleans, Dec. 4-8

Acoustical waves and vibrations allow us to hear and experience the world with fuller sensory stimulation. Acoustics has applications that cover a broad spectrum of topics including anthropogenic noise in marine environments, the dangers of hospital noise, and auditory sensitivity after drinking. The Acoustical Society of America’s fall meeting this year will showcase the diversity of sound and its applications, held Dec. 4-8, 2017, in New Orleans, Louisiana.

By analyzing data from randomized clinical trials comparing blood transfusion approaches, Johns Hopkins experts, along with colleagues at Cleveland Clinic and NYU Langone Medical Center, endorse recommendations for blood transfusions that reduce blood use to improve patient safety and outcomes. Publishing this week in JAMA Internal Medicine, the report also provides a how-to guide for launching a patient blood management program.

Johns Hopkins scientists report they have successfully used two separate gene technologies to assemble the most complete genome sequence to date of Triticum aestivum, the most common cultivated species of wheat used to make bread.

Raindrops Splash Pathogens Onto Crops

Pathogens, such as bacteria, viruses or fungi, cause harmful plant disease and often lead to the destruction of agricultural fields. With many possible dispersal methods, it can often be difficult to assess the damage of a pathogen’s impact before it’s too late. At the 70th meeting of the Division of Fluid Dynamics, Nov. 19-21, researchers from Virginia Tech will present their work on rain drop dispersal mechanisms of rust fungus on wheat plants.

'Magic' Sinus Paths Could Mean New Instructions for Nasal Sprays

APS-DFD_Basu_MagicalSinus.jpg

Sinus infections, inflammation and nasal congestion constantly plague Americans, often leading to unpleasant symptoms and even missed days of work. Traditional nasal spray anti-inflammatory medications attempt to treat the symptoms noninvasively, but are not very efficient in transmitting the active drug ingredients directly into the sinus cavities. Researchers from the University of North Carolina will present their research on the anatomy-based flow physics in nasal cavities which generate “magical” streamlines for sinus drug delivery at the 70th meeting of the Division of Fluid Dynamics, Nov. 19-21, 2017.

The Physics Behind Dandelion Seed Plume Dispersal Revealed

The fluffy dandelion seed head infuriates gardeners, but delights physicists. That’s because those seeds may lend key insights into the physics of parachutes, useful for designing small drones, or micro air vehicles. An interdisciplinary collaboration at the University of Edinburgh will present their findings on the topic at the 70th meeting of the Division of Fluid Dynamics, Nov. 19-21. Investigators reveal why, at low Reynolds numbers, the rules for big parachutes don’t apply to small dandelions.

Bubbles Clustering While Pouring Stout Beers?

Sugiyama-Beer-Bubbles.jpg

If you’ve poured a stout beer into a pint glass, you may have wondered about the or physics behind the rapid rise of bubbles and three-color shift when dark, medium and light shades are all clearly visible, before it transitions to simply beer and foam. During the 70th meeting of the Division of Fluid Dynamics, Nov. 19-21, 2017, researchers from will present their work exploring the fluid dynamics behind this type of bubble clustering in stout and nitrogenized stout beers and carbonated drinks.
