The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Time-domain Analysis Of Right Ventricular-pulmonary Arterial Coupling As A Windkessel And Wave System.
Funder
National Health and Medical Research Council
Funding Amount
$64,631.00
Summary
We seek to determine the number of people affected by pulmonary arterial hypertension (high blood pressure in the lungs) in Tasmania by collecting information from echocardiograms (heart ultrasounds). This is important because the incidence and prevalence is unknown but suspected to be unusually high in Tasmania. Also simultaneous pulmonary arterial pressure and velocity waves will be studied in humans to model pulmonary flow in an attempt to recognise pulmonary arterial hypertension earlier.
Optimising The Bone And Cardiovascular Response To Dietary Calcium: A Physiological Approach In Experimental Models
Funder
National Health and Medical Research Council
Funding Amount
$35,670.00
Summary
We aim to identify a variable calcium diet that optimises bone mass, density and strength as well as blood pressure in a rat model of intrauterine growth restriction. We propose that a moderate calcium diet followed by a high calcium diet is beneficial for bone and heart health. This is based on the physiological effect of reduced calcium intake stimulating intestinal calcium absorption. This represents a novel research approach to improving calcium intake, bone as well as heart health.
Coronary Atherosclerosis And Its Relationship With Platelet Activation
Funder
National Health and Medical Research Council
Funding Amount
$101,039.00
Summary
Blood clots are critical to the development of heart attacks, which kill many thousands of Australians annually. Platelets are cells in the blood that play an essential role in formation of blood clots, and coronary disease is associated with platelet activation. This research study will investigate the nature of platelet activation in the arteries of the human heart, its relationship to activation of inflammatory cells, and to the severity of narrowings in the arteries of the human heart.
Obstructive Sleep Apnoea As A Risk Factor For Atrial Fibrillation
Funder
National Health and Medical Research Council
Funding Amount
$64,631.00
Summary
Atrial fibrillation is the most common sustained cardiac arrhythmia and obstructive sleep apnoea is a common sleep-related breathing disorder. It has recently been suggested that OSA increases the risk of developing AF . The aim, therefore of this study, is to determine the incidence of sleep apnoea in our population of highly symtomatic patients with atrial fibrillation and to assess the outcome on arrhythmia burden of treatment with continuous positive airways pressure (CPAP).
Blood And Blood Product Transfusion In Trauma Resuscitation
Funder
National Health and Medical Research Council
Funding Amount
$98,431.00
Summary
Blood is an exceedingly scarce and expensive resource. Massive transfusions place enormous strains on blood banks. There is little consensus and a paucity of evidence on transfusion practice in major trauma. Trauma patients account for a significant proportion of all patients who receive transfusions. This project will assist with the development of more uniform guidelines for transfusion of blood products in major trauma patients based on the best evidence available and current practice.
