Hot-pressed silicon nitride with various lanthanide oxides as sintering additives [PDF]

open access: yes
The effects of addition of various lanthanide oxides and their mixture with Y2O3 on the sintering of Si3N4 were investigated. The addition of simple and mixed lanthanide oxides promoted the densification of Si3N4 in hot-pressing at 1800 C under 300-400kg/

Intraocular Osseous Metaplasia in Norfolk Black Turkey (Meleagris gallopavo): Clinicopathological Characterization of a Rare Avian Condition

open access: yesVeterinary Ophthalmology, EarlyView.
ABSTRACT Background Osseous metaplasia is a rare condition characterized by abnormal bone growth in soft tissues. Although documented in mammals, intraocular osseous metaplasia is uncommon in avian species and has been poorly characterized in turkeys (Meleagris gallopavo).

Ultrasonographic Ocular Biometry of the Greater Caribbean Manatee (Trichechus manatus manatus)

open access: yesVeterinary Ophthalmology, EarlyView.
ABSTRACT This study aimed to characterize the ocular biometry of the Trichechus manatus manatus applying B‐mode ultrasonography across different age groups. Twenty‐two animals were assessed employing a portable ultrasound device equipped with a linear transducer. Five ocular parameters were assessed: corneal thickness (CT), anterior chamber depth (ACD),
