APPROXIMATE INTERLAMINAR FRACTURE ENVELOPES FOR UNIDIRECTIONAL E-GLASS/POLYESTER COMPOSITE
, 2005
"... In this paper an experimental study is performed in order to determine an approximate interlaminar fracture envelope of a unidirectional E-glass polyester composite. First, the pure mode-I fracture toughness is determined by using the standard double-cantilever beam (DCB) specimen. Second, the pure ..."

NOTES Herpes Simplex Virus Envelopment and Maturation Studied by Fracture Label
, 1991
"... Herpes simplex virus envelopment and maturation were investigated by thin-section fracture label. The distribution of glycoproteins B and D was analyzed by labeling with antibodies; the precursor and mature forms of the glycoproteins were differentiated by labeling with the lectins concanavalin A (C ..."

Investigation and Numerical Verification
, 2007
"... The fracture initiation in ductile materials is governed by the damaging process along the plastic loading path. A new damage plasticity model for ductile fracture is proposed. Experimental results show that fracture initiation in uncracked ductile solids is sensitive to the hydrostatic pressure and ..."

is the plastic strain and the other is so-called damage variable. The joint effects of pressure and Lode angle define a fracture envelope in the principal stress space. Plastic deformation induced damage is expressed by an integral of the damage rate measured at current loading and deformation status
PUSHING THE ENVELOPE: DESIGNING WITH SEMI-STRUCTURAL PSAS
"... Pressure sensitive adhesives have been widely used for myriad non-structural applications, but capable products are making important inroads into semi-structural applications as well. Basic performance data such as tack, static shear, and peel properties may be helpful in selecting appropriate adhes ..."

STRUCTURE OF THE CELL ENVELOPE OF HALOBA CTERIUM HALOBIUM
"... The structure of the isolated cell envelope of Halobacterium halobium is studied by X-ray diffraction, electron microscopy, and biochemical analysis. The envelope consists of the cell membrane and two layers of protein outside. The outer layer of protein shows a regular arrangement of the protein or ..."

the outer protein layer by a 65/~-wide space which has an electron density very close to that of the suspending medium, and which can be etched after freeze-fracture. The space is tentatively identified as the periplasmic space. At NaC1 concentrations below 2.0 M, both protein layers of the envelope
Efficiency in the Treatment of Hip Fractures
, 1998
"... Abstract: This study addresses the issue of efficiency in the treatment and rehabilitation of hip fracture patients in Sweden. The treatment and rehabilitation of hip fracture patients is defined in terms of a hip fracture treatment process where resources in orthopaedics and after care are used for ..."

Each hip fracture treatment process is evaluated in terms of technical and allocative efficiency, using data envelopment analysis (DEA) which is a non-parametric linear programming technique. This method enables

, 2008
"... Maximum shear stress time consuming process. This is due to the experimental difficulties in maintaining a con-[10–13]. Recent development in ductile fracture modeling has extended the conventional I1, J2 type of continuum damage plasticity theory in the stress invariant space to a full three-dimens ..."

Membrane differentiations in freeze-fractured mammalian sperm
- J. Cell Biol
, 1974
"... A correlated thin-sectioning and freeze-fracturing study has been made of guinea pig and rat spermatozoa. In sections, the cell membrane over the acrosome has a concanavalin A and ruthenium red reactive glycocalyx which exhibits an ordered pattern related to the lattice of crystalline domains within ..."

"... It is shown that under conditions of uniaxial creep the fracture of high density polyethylene can be categorized as one of three types, depending upon the magnitude of the applied load, molecular architecture, and environment. When subjected to relatively large loads, the specimens neck and then fra ..."

It is shown that the uniaxial creep behavior for the region where drawing occurs, when plotted in terms of isochrones, represents a type of phase diagram, one boundary of which describes the fracture envelope. In addition, experiments employing different constant
