The distinctions inherent in the proximate-ultimate dichotomy have a long history. I examined several issues related to this distinction. It is important that distinctions among different problem areas be made so that the type of answer presented in research in animal behavior is appropriate for the type of questions being asked. This may require more than the two-way distinction between the pr...

Restricting path tracing to a small number of paths per pixel in order render images faster rarely achieves satisfactory image quality for scenes interest. However, space filtering may dramatically improve the visual by sharing information across vertices classified as proximate. Unlike screen approaches, these neither need be present on screen, nor is restricted first intersection with scene. ...

The aim was to improve nutritional quality of cows’ milk and use it as raw material for mozzarella cheese. Three treatments were tested with 23 healthy animals ranging power: control, palm oil and coconut oil. Collection was performed in 21 days and another after 36 days. Proximate composition (moisture, ash, fat, protein, carbohydrates), sensory, color (CIE L, a, b) and texture were made for m...
