Filling the Gaps MANY doctors pride themselves as being one of a team: or part of a comprehensive service, which will give the best attention to all the needs of the patient. The medical student or student nurse is trained to see team work in operation not only between the different specialists and between them and the various (so-called) "ancillary" services, but even with an increasing number...

In the manufacturing industry, nding an orientation for a mold that eliminates surface defects and insures a complete ll after termination of the gravity casting process, is an important and diicult problem. We study the problem of determining a favorable position of a mold (modeled as a polyhedron), such that when it is lled, no air bubbles and ensuing surface defects arise. Given a polyhedron...

It is possible to dress the quark propagator to all orders with zeromomentum gluons from the perturbative ground state. The dressed quark has no pole and thus cannot appear as an external particle in the S-matrix. Chiral symmetry may be spontaneously broken, but Lorentz and gauge symmetry is exact. Adding loop corrections to this “dressed tree approximation” gives a formally exact PQCD expansion.

SeeSys TM is a system embodying a technique for visualizing statistics associated with code that is divided hierarchically into subsystems, directories, and les. This technique can display the relative sizes of the components in the system, the relative stability of the components, the location of new functionality, and the location of error-prone code with many bug xes. Using animation, it can...

ABS TRACT This paper describes a lip filling technique that administers hyaluronic acid using microcannulas. This technique considerably reduces the number of punctures compared to the conventional method, which uses needles. In addition, the microcannula’s blunt tip reduces the risks of intravascular injection of the substance and of disrupting key structures such as vessels and nerves. The re...

Space filling curves have been used in the design of data structures for multidimensional data since many decades. A fundamental quality metric of a space filling curve is its “clustering number” with respect to a class of queries, which is the average number of contiguous segments on the space filling curve that a query region can be partitioned into. We present a characterization of the clust...

This study evaluated the efficiency of different techniques for removal of filling material from root canals, using computed tomography (CT). Sixty mesial roots from extracted human mandibular molars were used. Root canals were filled and, after 6 months, the teeth were randomly assigned to 3 groups, according to the root-filling removal technique: Group A - hand instrumentation with K-type fil...

In this study we investigated the effects of amalgam dental fillings on auditory thresholds. Participants (n=39) were non-smoking women age 40 to 45. Regression and correlation analyses were performed between auditory thresholds, measured from 0.25 to 16 kHz, and the number/surface area of dental fillings, using the ASHA criteria for ototoxic change as a reference for comparison. No significant...

this experiment was conducted to evaluate rate and duration of grain filling among old, modern and promising rice cultivars under different nitrogen levels in fields of  sari agricultural sciences and natural resources university, during 2008. two factors consisted of different urea fertilizer (0, 100 and 200 kg ha-1) as main plot and four promising lines (jelodar, partou, danesh and jahesh), 2...

BACKGROUND The mechanism of the alterations in the pattern of left ventricular (LV) filling during the development of congestive heart failure (CHF) is not fully understood. METHODS AND RESULTS We studied six conscious dogs instrumented to measure LV and left atrial (LA) pressures and LV volume as CHF was induced by rapid pacing. Diastolic filling dynamics were serially measured over 4 weeks ...
