SCORBUTIC BEADING OF THE RIBS [PDF]

open access: yesArchives 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 ...

Spatial Constraint Corrections to the Elasticity of dsDNA Measured with Magnetic Tweezers [PDF]

open access: yes, 2007
In this paper, we have studied, within a discrete WLC model, the spatial constraints in magnetic tweezers used in single molecule experiments. Two elements are involved: first, the fixed plastic slab on which is stuck the initial strand, second, the ...

A bead-assisted flow cytometry method for the semi-quantitative analysis of Extracellular Vesicles

open access: yesScientific Reports, 2017
Most experimental approaches commonly employed for the characterization and quantitation of EVs are time consuming, require of specialized instrumentation and often are rather inaccurate.

Making beads and bead making: an introduction

open access: yesAzania: Archaeological Research in Africa
Beads 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 ...

Pseudomonas aeruginosa Aggregate Formation in an Alginate Bead Model System Exhibits In Vivo-Like Characteristics

open access: yesApplied and Environmental Microbiology, 2017
Alginate beads represent a simple and highly reproducible in vitro model system for diffusion-limited bacterial growth. In this study, alginate beads were inoculated with Pseudomonas aeruginosa and followed for up to 72 h.

Numerical Analysis of Bead Magnetophoresis from Flowing Blood in a Continuous-Flow Microchannel: Implications to the Bead-Fluid Interactions

open access: yesScientific Reports, 2019
In this work, we report a numerical flow-focused study of bead magnetophoresis inside a continuous-flow microchannel in order to provide a detailed analysis of bead motion and its effect on fluid flow.

Spherical Vesicles Distorted by a Grafted Latex Bead: An Exact Solution

open access: yes, 2007
We present an exact solution to the problem of the global shape description of a spherical vesicle distorted by a grafted latex bead. This solution is derived by treating the nonlinearity in bending elasticity through the (topological) Bogomol'nyi ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation 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 ...
