Topography of the organs of the pelvic cavity and macroscopic and histologic findings of the sex organs of a male giant anteater (Myrmecophaga tridactyla) with regard to fertility
A study was conducted on the reproductive organs of a male Giant Anteater. Discussed is the specific anatomy with its effect on fertility. The ovoid testicles are characterized by an intraabdominal position throughout life. Histologically documented is the active spermiogenesis. The accessory sexual glands consist of a glandula prostatica, glandula vesiculares and glandulae bulbourethrales. The short penis is situated immediately ventral to the anus. The existing anatomic individualities in comparison to other mammalia result in special reproductive aspects and should be taken into consideration for successful breeding.
Geant4 [1] provides a software toolkit for the simulation of particles through matter. It has wide range of applicability, ranging from high-energy particle physics to space science. The physics description of Geant4 is in a constant process of improvement and validation. In this work a new relativistic Bremsstrahlung model is introduced. The key feature is a consistent description of matter effects, esp. the Landau-Pomeranchuk-Migdal (LPM) effect. The LPM effect will be of paramount importance for experiments at modern high-energy colliders, esp. the LHC, as well as in astroparticle physics applications.
