The Energy-Sources in Ontogenesis [PDF]
Journal of Experimental Biology, 1926 ABSTRACTThe percentage growth-rate curves for carbohydrate and protein in the chick enbryo have been determined and compared with those already in the literature for the percentage growth-rates of the whole embryo, the dry substance, the fat, and the calorific value. The composition of the embryo in gm.

The Anatomical Record, EarlyView.Abstract The crania of leporid lagomorphs are uniquely fenestrated, including the posterior cranial bones and the lateral portion of the maxilla. The functional significance of the highly fenestrated rostrum has received considerably little attention, despite being absent in other mammalian herbivores with a long rostrum.

Biosphere as semiosphere: Variations on Lotman
Sign Systems Studies, 2014 The analogy between semiosphere (world of cultures) and biosphere (world of life), coined by J. Lotman, is a courageous attempt to interconnect two seemingly incompatible worlds.

The Anatomical Record, EarlyView.We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

Place of the vitality analysis in population research and nature protection work
Біологічні студії, 2012 The basic stages of formation of the population analysis in ecology are considered. The attention to the special place and priorities of the population approach in modern exploratory and nature protection practice is paid.

The ontogenesis of the steroidogenic tissues [PDF]
Genes to Cells, 1997 Based on the common function of steroid hormone‐producing tissues and homologous regulation by the hypothalamo‐pituitary axis, the adrenal cortex and the gonads have been suggested to have an intimate ontogenic relationship. This assumption is also supported by the findings of common transcription factors implicated in the differentiation of both types

The Anatomical Record, EarlyView.Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Effect of gibberellic acid on total antioxidant activity during Chenopodium rubrum L. ontogenesis invitro [PDF]
, 2009 Total antioxidant activity (TAA) represents the combined ability of diverse antioxidants present in a sample of plant material to scavenge free radicals. Chenopodium rubrum L. sel. 184 is a qualitatively short-day plant; as an early-flowering species, it

Processor architectures for ontogenesis [PDF]
Proceedings. 2004 NASA/DoD Conference on Evolvable Hardware, 2004., 2004 In this article we present the outline of a novel processor architecture aimed to the design of systems that more closely resemble, within the limitations imposed by the capabilities of conventional silicon, the general modus operandi of multicellular organisms.

Ontogeny of murine bony semicircular canal form
The Anatomical Record, EarlyView.Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...
