In this article, we check and develop further some postulates of the theory and mathematical modeling of combined toxic effect that we proposed earlier [1]. To this end, we have analyzed the results of an experiment on rats exposed during 6 weeks to repeated intraperitoneal injections of lead acetate, sodium fluoride or both. The development of intoxication was estimated quantitatively with 54 ...

We investigated the process of yolk absorption in Korean rose bitterling, Rhodeus uyekii, and determined the changes in its morphometric characteristics. The R. uyekii from 1 days post hatching (DPH) to 21 DPH, the eye diameter (ED) was 5.4 at 5 DPH. Thereafter, the ED/total length (TL) ratio increased to 10.7 at 21 DPH (p<0.05). The yolk length (YL) decreased from 95.4 to 1.1 by 21 DPH, and th...

Richmond & Strait (2000) have attracted much attention with a recent morphometric analysis of distal radii of anthropoids and hominid fossils, suggesting some of the latter share knuckle-walking traits. Several aspects of their treatment deserve comment. These authors show A.L. 288-1q,v and the putative hominid fossil KNM-ER 20419 falling near chimpanzees and gorillas in a canonical analysis of...

Image-based classification of tissue histology, in terms of different components (e.g., subtypes of aberrant phenotypic signatures), provides a set of indices for tumor composition. Subsequently, integration of these indices in whole slide images (WSI), from a large cohort, can provide predictive models of the clinical outcome. However, the performance of the existing histology-based classifica...

Reservoirs are manmade habitats, intermediate between rivers and lakes, presenting distinct hydrological and morphometric characteristics, with differential mean water residence time. They also present proper vertical and horizontal organisations, and their evolution depends on several variables acting on different special and temporal scales. The water quality evolution of the Itaipu Reservoir...

The study was carried out to determine the morphometric indices and parasitic incidence of 160 fresh samples Synodontis nigrita comprising 80 each female male sexes. Fish were obtained from catches local fishermen along Lower River Benue at Wadata fish landing site State. Length–weight relationship analyzed using equation W=aLb. condition factor determined equation, K=100W/L3. Samples later sub...

Despite being inside a protected area, Lake Sumidouro has been impacted by the anthropogenic occupation of the surrounding area since the 1970's, compromising the ecological integrity of the lake and the sustainable use of natural resources. This study examined the current trophic classification of the lake and developed methods for improving it through an integrated analysis of morphometric an...
