Senior medical students have been utilized at some institutions in limited teaching roles for first-year medical students. The authors describe a pilot program in which a motivated senior medical student completely designed and taught an original course to a group of first-year students in academic year 2000-01. The 16-hour course was offered as a selective for first-year students. This course ...

Interfacial rheological properties have yet to be thoroughly explored. Only recently, methods have been introduced that provide sufficient sensitivity to reliably determine viscoelastic interfacial properties. In general, interfacial rheology describes the relationship between the deformation of an interface and the stresses exerted on it. Due to the variety in deformations of the interfacial l...

This paper presents a new method based on 3D reconstruction from images that demonstrates the utility and integration of close-range photogrammetry and computer vision as an efficient alternative to modelling complex objects and scenarios of forensic infography. The results obtained confirm the validity of the method compared to other existing alternatives as it guarantees the following: (i) fl...

The cuneiform-inscription (CI) signs recorded on the original clay tablet known as HS 158b from Nippur (1329 B.C.) have been characterized by the use of a multifunctional optoelectronic device. Properties such as features in object and Fourier space or similarity measures between the CI sign samples were investigated by the application of various numerical and experimental procedures. An overal...

STATEMENT OF PROBLEM The most widely used shade guide for composite materials is made of ceramic and arranged according to a non-proven method. There is a need for a composite shade guide using a scientifically based arrangement principle. PURPOSE To compare the shade tab arrangement of the Vitapan Classical shade guide and an individually made composite shade guide using both the originally ...

Eight centres throughout the United Kingdom cooperated with a prospective evaluation of the accuracy of surgery for horizontal strabismus. The eight centres were divided into four with a specialist interest in strabismus and four offering a general ophthalmic service. Each participating surgeon was asked to indicate the anticipated outcome of surgery and, thereafter, orthoptic examinations were...

A recently developed density functional theory (DFT) for tethered bead-spring chains is used to investigate colloidal forces for the good solvent case. A planar surface of tethered chains is opposed to a bare, hard wall and the force exerted on the bare wall is calculated by way of the contact density. Previously, the case of large wall separation was investigated. The density profiles of the u...

monosomy 21 is a rare chromosomal abnormality which is persented in mosaic or homogenous forms.the latter form which is very rare,is determined by intra uterin growth retardation)IUGR),failure to thrive (FTT),prominent craniofacial,skeletal deformities and differnt degrees of delay in psychomotor activities.we report an eight years old boy who was admitted in pediatric ward(hospital No 1 of Ker...

In an earlier report (Harman, Humphrey, & Goodale, 1999), we demonstrated that observers who actively rotated three-dimensional novel objects on a computer screen later showed faster visual recognition of these objects than did observers who had passively viewed exactly the same sequence of images of these virtual objects. In Experiment 1 of the present study we showed that compared to passive ...

With the advancement of new technologies, this author has in 2010 started to engineer an online learning environment for investigating the nature and development of spatial abilities, and the teaching and learning of geometry. This paper documents how this new digital learning environment can afford the opportunity to integrate the learning about 3D shapes with direction, location and movement,...
