Behavioural ecology Abstract Facial expressions convey information on emotion, physical sensations, and intent. The much debated theories that facial expressions can be emotions or signals of intent have largely remained separated in animal studies. Here we integrate these approaches with the aim to 1 investigate whether pigs may use facial expressions as a signal of intent and; 2 quantify differences in facial metrics between different contexts of potentially negative emotional state. Facial metrics of 38 pigs were recorded prior to aggression, during aggression and during retreat from being attacked in a dyadic contest. Prior to the occurrence of aggression, eventual initiators of the first bite had a smaller snout ratio and eventual winners showed a non-significant tendency to have their ears forward more than eventual losers. The results suggest that facial expressions can communicate aggressive intent related to fight success, and that facial metrics can convey information about emotional responses to contexts involving aggression and fear.

Triploidy Other defects with normal karyotype[ edit ] In fetuses with a normal number of chromosomes, a thicker nuchal translucency is associated with other fetal defects and genetic syndromes. The scan is obtained with the fetus in sagittal section and a neutral position of the fetal head neither hyperflexed nor extended, either of which can influence the nuchal translucency thickness. It is important to distinguish the nuchal lucency from the underlying amniotic membrane. Among those fetuses whose nuchal translucency exceeds the normal values, there is a relatively high risk of significant abnormality. Accuracy[ edit ] An increased nuchal translucency increases the probability that the fetus will be affected by a chromosomal abnormality , congenital cardiac defects , or intrauterine fetal demise.
Wide-angle IP cameras with 2mm focal length, in general, cover Wide-Angle Security Cameras: Meanwhile, super wide-angle outdoor cameras could sacrifice some details to get wider viewing angles, which makes it harder to identify faces or other small details. Therefore, wide-angle surveillance cameras CCTV or IP with varifocal lens do better to zoom out to cover large areas and zoom in to capture small details, for example, this wide-angle outdoor security camera RLC
The portable probe assures a constant distance from the skin as well as a fixed illumination angle of incidence; in this way is possible to acquire standardized and reproducible images. Secondary Outcome Measures: Skin electrical capacitance:
