A mechanism for sub-surface median crack initiation in glass during indenting and scribing
The initiation of sub-surface median cracks in glass during indenting and scribing is studied. It is shown that the zone of intense deformation under the tool introduces a weak singularity which may have a str...

Article
Composition and Structure Characterization of WNx Films Produced by RF Reactive Sputtering
WNx film is one of the most promising materials for self-aligned GaAs MESFET because of its low electrical resistivity and high Schottky Barrier Height at the WNx /GaAs contact.

Conformation Searching Using Simulated Annealing
Protein folding by direct computer-directed conformation searching is not yet possible (Brunger and Karplus, 1991). Two fundamental problems challenge researchers in this area. The first involves the general i...

A familial 46 XY gonadal dysgenesis and high incidence of embryonic gonadal tumors
The Swyer’s syndrome, 46XY gonadal dysgenesis (46XYGD) or XY female, belongs to the category of sexual abnomality. The syndrome is characterized by a female phenotype with streak gonads, 46XY karyotype and com...

Periodic structures and scaling Laws in a magnetic colloid
Phase separation was found in an eicosane-based ferrofluid in zero applied field. Upon applying a magnetic field, the condensed phase breaks up to form a lattice of periodic columns. The periodicity λ scales w...

Neutron Scattering from a Ferrofluid
Small angle neutron scattering experiments were performed on a eicosane-based ferrofluid. An average size of 88 Å can be extracted from the data, in agreement with results from electron microscopy. Below the f...

A class of singular perturbations for second order quasi-linear boundary value problems on infinite interval
We investigate the existence, uniqueness and asymptotic estimates of solutions for a class of second order quasi-linear singularly perturbed boundary value problem on the infinite interval when its reduced pro...

Acute effects of amiodarone on membrane properties, refractoriness, and conduction in guinea pig papillary muscles
Amiodarone has potent and complex antiarrhythmic effects associated with a rare incidence of proarrhythmia. For a comprehensive understanding of its antiarrhythmic mechanisms in the same preparations, amiodaro...

Computation of stress intensity factors for a 2-D body from displacements at an arbitrary location
An approach to stress intensity factor computation is presented which allows accurate estimation using a simple finite element program and a coarse mesh of elements. The stress intensity factor is obtained fro...

Alanyl-glutamine provides beneficial nutritional support after orthotopic transplantation of the liver in pigs
We evaluated the nutritional status of pigs that received glutamine after orthotopic liver transplantation. After transplantation, one group of pigs received an oral diet (group I,n=5), one group received convent...

Hypervariable allelic expression patterns of the imprinted IGF2 gene in tumor cells
The IGF2 gene, which encodes a growth factor, is subject to genomic imprinting. The frequently observed loss of IGF2 imprinting in a variety of tumors has been suggested to contribute to neoplasia. Since these re...

Human homologue of the Drosophila melanogaster lats tumour suppressor modulates CDC2 activity
We have previously used mosaic flies to screen for tumour suppressors or negative regulators of cell proliferation1. The cellular composition of these flies resembles that of cancer patients who are chimaeric ind...
