Oocyte ageing is a complex of processes that occur when matured in vitro oocytes are, after reaching the metaphase II stage, exposed to further in vitro culture. Aged oocytes remaining at the metaphas...
We study time averages of single particle trajectories in scale free anomalous diffusion processes, in which the measurement starts at some time t_a>0 after initiation of the process at the time origi...
Synthesis of Zeolite ZSM3 from Faujasite: Effects of Post-Synthesis Ageing and Insitu Seeding.
The ageing algebra is a local dynamical symmetry of many ageing systems, far from equilibrium, and with a dynamical exponent z=2. Here, new representations for an integer dynamical exponent z=n are co...
Granular packings slowly driven towards their instability threshold are studied using a digital imaging technique as well as a nonlinear acoustic method. The former method allows us to study grain rea...
Stress can speed ageing, study shows     stress  ageing       2009/8/26
A lifetime of stress can take its toll on the body and accelerate the ageing process, a study of wild animals suggests.Scientists at the University found that wild sheep forced to contend with difficu...
UQ neuroscientists have, for the first time, been able to demonstrate that moderate exercise significantly increases the number of neural stem cells in the ageing brain. In research published in Stem ...
During airborne in situ measurements of particle size distributions in a forest fire plume originating in Northern Canada, an accumulation mode number mean diameter of 0.34 mm was observed over Linden...
Black carbon (BC) particles in the atmosphere have important impacts on climate. The amount of BC in the atmosphere must be carefully quantified to allow evaluation of the climate effects of this type...
A new kind of data analysis is discussed – and a few case histories of actual application are presented – concerning the physical information attainable by acoustic emission (AE) records in geodynamic...
We present a complete description of the Penna bit-string model for biological ageing and how it has been modified, along the last 10 years, to simulate and better understand many different evolutiona...
