the problem of several finite moving cracks in a functionally graded material is solved by dislocation technique under the condition of anti-plane deformation. by using the fourier transform the stress fields are obtained for a functionallygraded strip containing a screw dislocation. the stress components reveal the familiar cauchy singularity at thelocation of dislocation. the solution is empl...

BACKGROUND The surgical management of obstetrical brachial plexus palsy can generally be divided into two groups; early reconstructions in which the plexus or affected nerves are addressed and late or palliative reconstructions in which the residual deformities are addressed. Tendon transfers are the mainstay of palliative surgery. Occasionally, surgeons are required to utilise already denervat...

PURPOSE To compare accuracy of intraocular lens (IOL) power calculation formulae in infantile eyes with primary IOL implantation. DESIGN Comparative case series. METHODS The Hoffer Q, Holladay 1, Holladay 2, Sanders-Retzlaff-Kraff (SRK) II, and Sanders-Retzlaff-Kraff theoretic (SRK/T) formulae were used to calculate predicted postoperative refraction for eyes that received primary IOL impla...

AIM To evaluate the prediction error in intraocular lens (IOL) power calculation for a rotationally asymmetric refractive multifocal IOL and the impact on this error of the optimization of the keratometric estimation of the corneal power and the prediction of the effective lens position (ELP). METHODS Retrospective study including a total of 25 eyes of 13 patients (age, 50 to 83y) with previo...

The adrenochrome hypothesis of schizophrenia (Hoffer, Osmond and Smythies, 1954), was stimulated by the work of Osmond and Smythies (1952) which focused on methylated derivatives of adrenalin as possible endogenous schizophrenogens. They showed that the experience which followed the ingestion of mescaline was in many ways similar to the experience induced in normal people by schizophrenia. This...

An important goal of schooling is to support students’ personal well-being, including to enhance their self-esteem (Bagley, 1989b; Bagley, Verma, Mallick, & Young, 1979). Self-esteem and self-concept (used as interchangeable constructs) are linked to scholastic achievement (Byrne, 1990), and, according to Kaplan (1980), inversely to school drop-out, delinquency, premature sexual activity, unwan...

BACKGROUND Reconstruction of Charcot feet remains a surgical challenge. The goal of this study was to investigate safety and clinical benefit from reconstruction of Charcot feet using an external fixator. There is limited valid data regarding long-term outcomes for Charcot foot procedures. METHODS In a retrospective study, 292 Charcot feet (282 patients) undergoing reconstructive procedures i...

Persons with conventionally treated insulin-dependent diabetes mellitus (IDDM) appear to be impaired in their ability to reduce fed-state urea production appropriately in response to dietary protein restriction (Hoffer LJ, Taveroff A, and Schiffrin A. Am J Physiol 272: E59-E67, 1997). To determine whether these conclusions apply to whole body sulfur amino acid (SAA) catabolism, we used samples ...

i Unified modeling language (UML) is a modeling language sponsored by a prominent consortium of companies, the object management group (OMG), for object-oriented (OO) systems development (Kobryn, 1999, 2004). It is widely acknowledged that UML has become the de facto standard for modeling object-oriented software development (Pender, 2003). It is used in specifying, visualizing, constructing, a...
