An operative problem in stereometric evaluations with nonautomatized computation


, : An operative problem in stereometric evaluations with nonautomatized computation. Physis Seccion A los Oceanos y sus Organismos 37(93): 51-57

In Illex argentinus Castellanos (Cephalopoda, Ommastrephidae) mature ovary 7 kinds of oocytes, varying in diameter between 20 and 900 .mu., are distinguished. This 1:40 relationship between the oocyte sizes is not fully valid for the stereometric evaluation of each of the 7 layers, mainly because of high theoretical dispersion resulting from an operating punctual reticulum of 100 points, which affects the oocyte types volumetrically less represented. Relative dispersions and the real relative deviations are compared. A model of the oocyte size structure in a centimeter scale with remittant errors smaller than expected, was implemented. The need for elaborating a reference model for each particular case is emphasized.

Ornithodoros moubata ticks were fed on blood infected with Babesia equi. However, the parasites were quickly cleared as evidenced by the disappearance of B. equi-specific ribosomal RNA from the ticks. We hypothesized that if the Babesia parasite c...
