In this paper, the effects of stacking sequence and ply orientation on mechanical properties pineapple leaf fibre (PALF)/carbon hybrid laminate composites were investigated. The laminates fabricated using a vacuum infusion technique in which sequences orientations varied, divided into categories cross-ply symmetric, angle-ply symmetric quasi-isotropic. results tensile flexural tests showed that...

Streptococcus pneumoniae is the causative agent of multiple diseases, including otitis media, pneumonia, bacteremia, and meningitis. Pneumolysin (Ply), a member of the cholesterol-dependent cytolytic pore-forming toxins, is produced by virtually all clinical isolates of S. pneumoniae, and strains in which the Ply gene has been deleted are severely attenuated in mouse models of infection. In con...

OBJECTIVE To evaluate the monthly frequency of larvae and pupae of Aedes albopictus, Aedes aegypti and other mosquitoe species in tires, and the influence of environmental factors on that. METHODS The immature stages of mosquitoes were collected monthly from four tires in the municipality of Nova Iguaçu, Brazil, from November 1997 to October 1998. The following variables were measured: rainfa...

We consider the recently introduced model of low ply graph drawing, a straight-line drawing in which the ply-disks of the vertices do not have many common overlaps, which results in a good distribution of the vertices in the plane. The ply-disk of a vertex is the disk centered at it whose radius is half the length of its longest incident edge. We focus our attention on low-ply drawings of trees...

In 1985, the scrap tire industry was created when Minnesota became the first state to develop specific legislation and regulations for scrap tires. Up to that time, many scrap tires, like most solid and household wastes, went into the l1)unicipal dump. Those tires not placed in the dump went into stock piles, some of which still exist today. Prior to 1985, few, ifany scrap tires were processed....

This paper is the second of a two-part series assessing the feasibility of using the J-integral with full-field deformation data from Digital Image Correlation (DIC) to characterize toughness in continuous fiber, SiCf/SiCc ceramic matrix composites (CMCs). In Part I, line and area integral adaptations of the J-integral were validated with analytical and experimental deformation fields. It was f...

The cholesterol-dependent cytolysin (CDC) pneumolysin (Ply) is a key virulence factor of Streptococcus pneumoniae. Membrane cholesterol is required for the cytolytic activity of this toxin, but it is not clear whether cholesterol is the only cellular receptor. Analysis of Ply binding to a glycan microarray revealed that Ply has lectin activity and binds glycans, including the Lewis histo-blood ...

Given a straight-line drawing Γ of a graph G = (V,E), for every vertex v the ply disk Dv is defined as a disk centered at v where the radius of the disk is half the length of the longest edge incident to v. The ply number of a given drawing is defined as the maximum number of overlapping disks at some point in IR. Here we present a tool to explore and evaluate the ply number for graphs with ins...
