A new microwave imaging technique is proposed for reconstruction of 2-D complex permittivity profiles in dielectric samples located in a waveguide system. The spatial distributions of the dielectric constant and the loss factor are approximated by continuous functions whose functional parameters are determined using a neural network technique backed by(More)
Data about some genetic factors of male infertility are presented, and methods, which may be used for its diagnosing, are studied. Among genetic factors the following are distinguished: changes in the level of genes (mutations), chromosomes (chromosomal aberrations), and total DNA (chromatin dispersion and DNA fragmentation). As well as standard cytogenetic(More)
The results of molecular cytogenetic study of spontaneous abortions and material non progressive pregnancies in the first trimester in 43 couples who were treated with various methods of ART are presented in this report. Chromosomal pathology (CP) was present in 28 (65 %) samples of chorionic villi. A comparative analysis of the frequency and types of CPs(More)
Data about some male infertility genetic factors is presented and methods that can be used for its diagnostics are considered. Among genetic factors changes of the genetic apparatus at gene level (mutations), chromosome level (chromosomal aberrations), and total DNA (chromatin dispersion, DNA fragmentation) are pointed out. Beside standard cytogenetic(More)
A model of organism adaptation under its normal functioning, being transferred without any conceptual changes into the adaptation model to the stimulating actions, at which the organism malfunctions and is forced to transfer to the regime of pathology which is considered to be the only possible regime for extreme conditions. As examples the cases of(More)
