Mechanical Engineering Department hono ugg australia urs student Amanda Robbins was walking on air with the news she would be conducting part of her research at NASA facilities.

Ms Robbins recently spent three weeks working at NASA’s White Sands Test Facility in Las Cruces, New Mexico, and the NASA Johnson Space Centre in Houston, Texas, for her thesis project on gravity’s effect on fluids.

Experiments conducted under reduced gravity conditions allow greater scrutiny of other, more subtle effects on liquid streams such as surface tension.

“A knowledge of the behaviour of fluids as they break up into droplets is vital for improving the production of materials involving small particles including fertilisers and explosives and in the powder drying of foods,” Ms Robbins said.

“In fertiliser production, manufacturers continue to strive for a process yielding uniform particle size to reduce the chances ugg australia of end users such as farmers inhaling smaller, dust sized particles when they open bags.

“In explosive production, the more uniform the particle size, the more predictable and reliable the explosion.”

The tests represent the first time experiments in the field have been conducted over longer durations of reduced or microgravity (between 15 and 25 seconds). These conditions are achieved by placing a test box inside NASA’s specially modified “Weightless Wonder V” aeroplane.

Twenty five seconds of weightlessness are achieved as the plane suddenly drops from 35,000 feet to 15,000 feet. Returning to its initial altitude each time, it completes this rapid descent 40 times in two hours over the Gulf of Mexico.

“In the past, these experiments have only been conducted using ground based drop towers capable of producing microgravity (reduced gravity) for a maximum of 2.2 seconds,” Ms Robbins said.

Supervised by Department senior lecturer Dr Ted Steinberg and funded by a 1998 Australian Research Council small grant of $25,000, the project is believed to be the first University of Queensland undergraduate work to have access to the $75,000 a week plane.

“I was granted space on the flight due to Dr Steinberg’s lo ugg australia ngstanding NASA connections formed through his ongoing microgravity combustion experiments. While I won’t be travelling on ugg australia the plane this trip, there is a possibility I will get on board next time around,” Ms Robbins said.

UQ tennis elbow study seeks volunteers

30 July 2009Nearly 100 people have already participated in a UQ clinical research study into tennis elbow, but researchers are still seeking more volunteers.

The multi centre trial is currently investigating the effect of different combinations of injections and physiotherapy treatments for ugg australia tennis elbow.

Chair in Sports Physiotherapy and Head of the Division of Physiotherapy at UQ Professor Bill Vicenzino said the common musculoskeletal condition presented as pain over the thumb side (outside) of the elbow.

“For example, it can occur in people who usually do office work and then either do a bout of gardening or r ugg australia enovations at home after hours,” Professor Vicenzino said.

“The pain is noticeable when the patients use ugg australia his or her hand to manipulate things for example, when shaking hands, lifting a tea cup or pot or even light, one cup pots, lifting shopping bags, opening doors and pulling up pants.”

Study participant Ashley Wilkinson said the study allowed her to seek treatment for tennis elbow as well as learn of methods to prevent the condition reoccurring.

“I definitely noticed I wasn’t playing as much tennis due to tennis elbow,” Ms Wilkinson said.

If you have experienced pain on the outside of your elbow for more than six weeks, you may be eligible for a free assessment and treatment.

Sufferers will be required to attend a one hour assessment at UQ’s St Lucia campus to determine their suitability for the study.

People with no history of tennis elbow or other current neck or arm pain are also needed for a single assessment. Results ugg australia of gripping and arm strength, pressure and temperature measurements will be provided to participants.

Assessments can be scheduled after hours with parking vouchers provided. Study treatments can also be arranged at one of 15 practice locations throughout Brisbane for convenience.
