Ritual female genital operations are common in many parts of the world, with varying degrees of mutilation from clitoridectomy and removal of the labia to removal of the clitoral prepuce. Interviews of 21 Bedouin women in southern Israel revealed the practice to be normative in several tribes. However, physical examination of 37 young women from those(More)
The simplest model of a smart spatial redistribution of individuals is proposed. A single-species population is considered, to be composed of two discrete subpopulations inhabiting two stations; migration is a transfer between them. The migration is not random and yields the maximization of net reproduction, with respect to the transaction costs. The(More)
The authors report on their experience with venous bypass in situ performed in 54 patients. For disruption of venous valves they constructed a simple stripper of the Connolly type. The method of bypass in situ is described in detail and its advantages are discussed. For reconstructive operations below the knee the bypass in situ should be preferred over the(More)
After their long lasting experience with commercially prepared fibrinogen for sealing off ultraporous vascular prostheses, the authors have introduced the use of freshly prepared fibrinogen from the patient's own blood. This approach provides an additional advantage by allowing to substitute the blood losses at the operation with shelfed autologous blood.(More)
A novel model of thermal regulation of homoeothermic animals has been implemented. The model is based on a non-equilibrium thermodynamic approach which introduces entropy balance and the rate of entropy generation as a formulation of The Second Law. The model explains linear correlation between an animal's skin and environment temperatures using the first(More)
The authors report on their four-year experience with the use of extremely highly porous vascular polyester prostheses of Czechoslovak proveniencè, whose wall was sealed with fibrin. Aortofemoral bifurcated prostheses with a permeability of 6 100 ml/cm2/min were implanted in 102 patients. The method of fibrination appears to be simple and safe. No(More)
We consider the model of spatially distributed community consisting of two species with "predator-prey" interaction; each of the species occupies two stations. Transfer of individuals between the stations (migration) is not random, and migration stipulates the maximization of net reproduction of each species. The spatial distribution pattern is provided by(More)
