Arching in three-dimensional clogging [PDF]

open access: yesEPJ Web of Conferences, 2017
Arching in dry granular material is a long established concept, however it remains still an open question how three-dimensional orifices clog. We investigate by means of numerical simulations and experimental data how the outflow creates a blocked ...

Tumor Shape-Specific Brachytherapy Implants by 3D-Printing, Precision Radioactivity Painting, and Biomedical Imaging. [PDF]

open access: yesAdv Healthc Mater, 2023
Additive manufacturing of a hard and biocompatible polymer such as polyetheretherketone allows the fabrication of anatomically relevant applicators for brachytherapy (internal radiotherapy), and the application of radioactivity on these implants according to different patterns allows to modulate the energy dose profiles delivered to tumors.

Cranial osteology of Hypoptophis (Aparallactinae: Atractaspididae: Caenophidia), with a discussion on the evolution of its fossorial adaptations. [PDF]

open access: yesJ Morphol, 2022
We have thoroughly described the cranial osteology and inner ear of Hypoptophis wilsonii—the first μCT‐based description of the aspects of cephalic anatomy of any snake belonging to subfamily Aparallactinae. The skull bones and the inner ear of this species are adapted for burrowing, with many of these adaptations characterizing other aparallactines ...

Concave Regular Faced Cupolae of Second Sort

open access: yes, 2008
Cupola is a polyhedron which is consisted of two regular polygons: n-gon and 2n-gon in parallel planes, connected by alternating sequence of squares and equilateral triangles, i.e. Johnson’s solids J3, J4 and J5. However, it is possible to form a polyhedron with the analogously chosen regular n-gon and 2n-gon in parallel planes, in that manner to have ...

A novel automated instrument designed to determine photosensitivity thresholds (Conference Presentation)

open access: yesSPIE BiOS, 2016
As there is no clinically available instrument to systematically and reliably determine the photosensitivity thresholds of patients with dry eyes, blepharospasms, migraines, traumatic brain injuries, and genetic disorders such as Achromatopsia, retinitis

Composite concave cupolae as geometric and architectural forms

open access: yes, 2015
Summary: In this paper, the geometry of concave cupolae has been the starting point for the generation of composite polyhedral structures, usable as formative patterns for architectural purposes. Obtained by linking paper folding geometry with the geometry of polyhedra, concave cupolae are polyhedra that follow the method of generating cupolae (Johnson'

Possibilities of Deltahedral Concave Cupola Form Application in Architecture

open access: yes, 2011
In recent years, we are witnessing an increasing use of triangular modular building systems, which, especially in representative objects, almost push out the orthogonal system. Considering that deltahedra are assembled of equilateral triangles matching system, we investigated a possible application of such polyhedral forms in geometry of architectural ...

Experimental and industrial method of synthesis of optimal control of the temperature region of cupola melting

open access: yesEUREKA: Physics and Engineering, 2023
The object of research is the temperature regime of melting in a cupola. The synthesis of optimal control of such an object is associated with the presence of a problem consisting in the complexity of its mathematical description and the absence of ...

Osteology of the enigmatic threadsnake species Epictia unicolor and Trilepida guayaquilensis (Serpentes, Leptotyphlopidae) with generic insights

open access: yesThe Anatomical Record, Volume 304, Issue 10, Page 2183-2197, October 2021., 2021
Abstract Since the rearrangement of all leptotyphlopid species previously known as “Leptotyphlops” in Adalsteinsson et al. (2009)'s paper, several taxa have remained untested regarding their generic identity and have been assigned to different genera based on phenotypic data or, in some cases, without any clear justification.
