(Press-News.org) Infrared satellite imagery tells the temperature of the cloud tops within a tropical cyclone as well as the sea surface temperatures around the storms. A recent infrared image from NASA's Aqua satellite showed very little strength in the remnants of ex-cyclone Tim offshore from southeastern Queensland.
The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite captured an infrared image of Cyclone Tim on March 18 at 0355 UTC (March 17 at 11:55 p.m. EDT). The AIRS image showed that cloud top temperatures had warmed significantly since the previous day as the low pressure area continues to weaken. The coldest cloud top temperatures and strongest thunderstorms appeared in small area offshore from southeastern Queensland.
On March 18 at 1200 UTC (8 a.m. EDT/10 p.m. local time, Brisbane, Queensland, Australia), the remnants of ex-cyclone Tim was located near 19.1 south latitude and 151.7 east longitude, was located about 190 nautical miles (218.6 miles/ 352 km) northeast of Mackay. Tim's remnants were drifting west at 2 knots (2.3 mph/3.7 kph). The Australian Bureau of Meteorology (ABOM) noted that Tim's remnants are causing rough to very rough seas and moderate south to southeasterly swell. According to ABOM, wind gusts to 40 knots (46 mph/74 kph) are possible from Tim's remnants.
As a result of Tim's close proximity to the Queensland coast, several warnings were posted on March 18 at 2:15 p.m. EDT/U.S. (12:15 a.m. local time, Brisbane on Tuesday, March 19). A Gale Warning is in effect from Townsville to Bowen and from Bowen to Yeppoon, Strong Wind Warnings are in effect from Cardwell to Townsville and from Yeppoon to Double Island Point, including Hervey Bay. A Coastal Waters Wind Warning was also posted for Cardwell to Double Island Point, including Hervey Bay.
ABOM expects Tim's remnants to move in a west-northwest direction towards the Queensland coast over the next few days.

Uncontrolled hypertension could bring increased risk for Alzheimer's disease
2013-03-19
A study in the JAMA Neurology (formerly the Archives of Neurology) suggests that controlling or preventing risk factors such as hypertension earlier in life may limit or delay the brain changes associated with Alzheimer's disease and other age-related neurological deterioration.
Dr. Karen Rodrigue, assistant professor in the UT Dallas Center for Vital Longevity (CVL), was lead author on a study that looked at whether people with both hypertension and a common gene associated with risk of Alzheimer's disease (the APOE-4 gene carried by about 20 percent of the population) ...
Tourist-fed stingrays change their ways
2013-03-19
Stingrays living in one of the world's most famous and heavily visited ecotourism sites — Stingray City/Sandbar in the Cayman Islands — have profoundly changed their ways, raising questions about the impact of so-called "interactive ecotourism" on marine wildlife, reports a new study published March 18 in the journal PLOS ONE.
Researchers from Nova Southeastern University's Guy Harvey Research Institute in Hollywood, Fla., and the University of Rhode Island studied the southern stingray population of Stingray City — a sandbar in the Cayman Islands that draws nearly a ...
Discounts on purchases of healthy foods can improve diets, study finds
2013-03-19
Lowering the costs of healthy foods in supermarkets increases the amount of fruits, vegetables and whole grain foods that people eat, while also appearing to reduce consumption of nutritionally less-desirable foods, according to research from the RAND Corporation.
Researchers examined a program available to members of South Africa's largest private health insurance company that provides a rebate of 10 percent or 25 percent on purchases of healthy foods. The program, started in 2009, now has about 800 participating supermarkets and enrolls more than 260,000 households. ...
Cushioned heel running shoes may alter adolescent biomechanics, performance
2013-03-19
CHICAGO — Many of today's running shoes feature a heavy cushioned heel. New research presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) found that these shoes may alter an adolescent runner's biomechanics (the forces exerted by muscles and gravity on the skeletal structure) and diminish performance.
Researchers recruited 12 adolescent competitive athletes from local track teams, and asked them to run on a treadmill in large heel trainers, track flats and without any shoes (barefoot) at four different speeds. Biomechanics ...
Sexual function improves significantly after hip or knee replacement surgery
2013-03-19
CHICAGO — Osteoarthritis of the hip or knee, affecting millions of Americans each year, is known to limit sexual activity. New research presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) found that total hip (THR) or total knee replacement (TKR) surgery improves sexual function in 90 percent of patients.
In the study, 147 patients under age 70, scheduled for primary THR or TKR, agreed to participate in a study requiring the completion of questionnaires prior to surgery, at six months post surgery, and at one year post surgery. ...
Sports and recreation injuries drop 12 percent for children ages 5-14 during past decade
2013-03-19
CHICAGO — New research presented today at the at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) found that overall, sports and recreation musculoskeletal injuries have declined 12.4 percent in the U.S. over the past 10 years for children ages 5 to 14 years. However, injuries sustained during football and soccer continues to rise.
In 2000, the U.S. Centers for Disease Control (CDC) reported the top eight sports and recreational activities responsible for injuries in children ages 5 to 14, and estimated their annual cost at more than $33 ...
MRI may predict adverse tissue reaction in metal-on-metal hip replacement patients
2013-03-19
CHICAGO – Magnetic Resonance Imaging (MRI) can detect a failing, or potentially failing, metal-on-metal hip implant (MoM) early on, according to a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). Early detection can result in timely revision surgery, decreasing the risk for further tissue damage and pain.
Researchers reviewed the MRI images of 70 patients who ultimately underwent revision surgery for a failed MoM implant. The images were assessed for the presence of tissue damage, swelling and other characteristics. ...
Returning military personnel to duty following severe injury to the lower extremity
2013-03-19
CHICAGO – High-energy lower-extremity trauma (HELET) is common in modern warfare, often resulting in severe tissue damage, chronic pain, neurovascular injury and significant muscle loss, according to the new research presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS).
The Return to Run (RTR) program is an integrated orthotic and rehabilitation initiative designed to return high-level function to wounded warriors. It includes use of the new Intrepid Dynamic Exoskeletal Orthosis (IDEO), a custom-fit device made from carbon ...
Spine patients who quit smoking report diminished pain
2013-03-19
CHICAGO – Smoking is a known risk factor for back pain and disc disease. In a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers reviewed smoking cessation rates and related pain in 6,779 patients undergoing treatment for spinal disorders with severe axial (spine) or radicular (leg) pain. Information on each patient's age, gender, weight, smoking history, assessment of pain, treatment type and co-morbid depression also were assessed.
Overall, 8.9 percent of patients over the age of 55 smoked compared ...
Living in a sunny climate does not improve vitamin D levels in hip fracture patients
2013-03-19
CHICAGO – While it is well known that a majority of hip fracture patients of all ages and both sexes have insufficient or deficient levels of vitamin D, a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) looks at whether or not living in a warm, sunny climate improves patient vitamin D levels.
Researchers retrospectively reviewed the vitamin D levels of 1,539 patients, including 448 acute hip fracture patients and 1,091 total hip (THR) or total knee replacement (TKR) patients, from December 2010 to December 2011 ...
