The goal of this study was to investigate the performance of 3D synchrotron differential phase contrast (DPC) imaging for the visualization of both macroscopic and microscopic aspects of atherosclerosis in the mouse vasculature ex vivo. The hearts and aortas of 2 atherosclerotic and 2 wild-type control mice were scanned with DPC imaging with an isotropic resolution of 15 μm. The coronary artery...

Events leading to cell wall formation in the ellipsoidal unicellular alga Glaucocystis are described. The wall is deposited in three phases: (a) a thin nonfibrillar layer, (b) cellulosic microfibrils arranged in helically crossed polylamellate fashion, and (c) matrix substances. At poles of cells, microfibrils do not terminate but pass around three equilaterally arranged points, resulting in mi...

Recent progress in microand nanofabrication techniques enables the creation of hierarchically architected microlattices with dimensional control over six orders of magnitude, from centimeters down to nanometers. This hierarchical control facilitates the exploration of opportunities to exploit nano-sized material effects in structural materials. In this work, we present the fabrication, characte...

The paper deals with the description of particle deposition on walls from a turbulent flow over a large range of particle diameter, using a Langevin PDF model. The first aim of the work is to test how the present Langevin model is able to describe this phenomenon and to outline the physical aspects which play a major role in particle deposition. The general features and characteristics of the p...

3D concrete printing is a perspective technology for sustainable construction and realization of sophisticated architectural projects. The current research proposes the thermal engineering calculation wall structure based on printed element total thickness 150 mm with internal air layer about 75 mm. mixture was designed addition perlite as filler in dosage 8 % by weight cement. process performe...

A method to triangulate the medial axis [1] is modified. In the new method the coping surfaces of a thin-wall object are used for insidedness but ignored for footpoints, yielding the mid-surface, not the medial axis. Three distinct contour-followers are employed. After a brief, manual tagging of the coping surfaces, the method is automatic. It computes a triangulation to arbitrary precision and...
