Arts, 2013 This comprehensive overview considers the currently known Pleistocene palaeoart of Asia on a common basis, which suggests that the available data are entirely inadequate to form any cohesive synthesis about this corpus.

SCORBUTIC BEADING OF THE RIBS [PDF]
Archives of Pediatrics and Adolescent Medicine, 1920 For many years beading of the ribs has been regarded as a sign characteristic of rickets. The "rachitic rosary" is sought for in order to establish the diagnosis, and its presence is considered pathognomonic of this disorder. In the course of a study of rickets begun about two years ago, we became especially interested in this sign, which was found to ...

Making beads and bead making: an introduction
Azania: Archaeological Research in AfricaBeads are a prominent category of material culture in the African past. Crosscutting their study across temporal periods and geographical areas are some general methodological and theoretical convergences: the categorisation of beads in terms of materials and methods of manufacture, an emphasis on provenance and distribution, and the analysis of beads ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

An improved encapsulation protocol for regrowth and conservation of four ornamental species
Acta Societatis Botanicorum Poloniae, 2017 The encapsulation technology, initially developed for clonal propagation through the production of synthetic seeds with somatic embryos, is currently proposed for use with non-embryogenic explants, such as buds and nodal segments (unipolar propagules ...
