Projectile Trajectory of Penguin's Faeces and Rectal Pressure Revisited [PDF]

arXiv, 2020
We discuss a trajectory of penguins' faeces after the powerful shooting due to their strong rectal pressure. Practically, it is important to see how far faeceses reach when penguins expel them from higher places. Such information is useful for keepers to avoid the direct hitting of faeceses.

Dosimetric uncertainties related to the elasticity of bladder and rectal walls: Adenocarcinoma of the prostate [PDF]

cancer radioth\'erapie 15, 3 (2011) 168-240, 2011
Purpose. - Radiotherapy is an important treatment for prostate cancer.During treatment sessions, bladder and rectal repletion is difficult to quantify and cannot be measured with a single and initial CT scan acquisition. Some methods, such as image-guided radiation therapy and dose-guided radiation therapy, aimto compensate thismissing information ...
