Feline caudal vena cava to aorta ratio reference interval.

Objectives: The primary objective of this investigation was to ultrasonographically evaluate the caudal vena cava to aorta (CVC:Ao) ratio in healthy, conscious cats and to generate reference intervals. A secondary objective was to identify the site of examination with the least intra- and inter-observer variability. This investigation was undertaken to assess whether the CVC:Ao ratio holds promise as a technique to assess intravascular volume responsiveness in cats.

Lifetimes and mechanisms of biodegradation of polyhydroxyalkanoate (PHA) in estuarine and marine field environments.

Coastal cities face significant challenges from plastic pollution, with most plastics being resistant to biodegradation. Biodegradable plastics are increasingly used to address this issue, particularly for items prone to entering, and then accumulating, in waterways, through littering or leakage. Among biodegradable plastics, polyhydroxyalkanoates (PHAs) are notable as bioderived, bacterially synthesised aliphatic polyesters that are readily biodegradable in varied environments.

Morality in Our Mind and Across Cultures and Politics.

Moral judgments differ across cultures and politics, but they share a common theme in our minds: perceptions of harm. Both cultural ethnographies on moral values and psychological research on moral cognition highlight this shared focus on harm. Perceptions of harm are constructed from universal cognitive elements-including intention, causation, and suffering-but depend on the cultural context, allowing many values to arise from a common moral mind.

An energy-modified quantum defect method for the analysis of Rydberg spectra: Application to 2-butyne.

The high resolution Rydberg absorption spectrum of 2-butyne C4H6 recorded previously at the SOLEIL synchrotron facility has been interpreted using multichannel quantum defect theory (MQDT). The calculations are based on the continuum scattering calculations of Xu et al., J.
