Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

open access: yesThe Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Body donor programs in Australia and New Zealand: Current status and future opportunities

open access: yesAnatomical Sciences Education, Volume 18, Issue 3, Page 301-328, March 2025.
Abstract Body donation is critical to anatomy study in Australia and New Zealand. Annually, more than 10,000 students, anatomists, researchers, and clinicians access tissue donated by local consented donors through university‐based body donation programs. However, little research has been published about their operations.

Sustainable development of refrigerator systems using replacement environmentally acceptable refrigerants [PDF]

open access: yes
Environmental considerations have led to the phase out of chlorofluorocarbon (CFC) refrigerants from the domestic refrigeration industry. One intriguing aspect is that the \ud chlorine in CFCs is a good lubricating agent and any deterioration of system performance may adversely influence other environmental considerations.
