Purpose: Implant length, implant surface area, and crown-to-root (c/r) ratio and their relationship to crestal bone levels were analyzed in 2 groups of partially edentulous patients treated with sintered porous-surfaced dental implants. Materials and Methods: One hundred ninety-nine implants were used to restore 74 partially edentulous patients with fixed prostheses. Implants were categorized a...

How proteins with new functions (e.g., drug or antibiotic resistance or degradation of man-made chemicals) evolve in a matter of months or years is still unclear. This ability is dependent on the induction of new phenotypic traits by a small number of mutations (plasticity). But mutations often have deleterious effects on functions that are essential for survival. How are these seemingly confli...

Background. This study is an attempt to combine and compare EEG, MEG and functional magnetic resonance imaging (FMRI) methods to map the somatotopic organization of primary somatosensory cortex. Methods. 32-channel EEG and 143-channel MEG recordings were acquired from two subjects during tactile stimulation of the fingertips. In addition, FMRI activation maps were produced during fingertip vibr...

Strains of methicillin-resistant Staphylococcus aureus (MRSA) were detected in 1961, shortly after methicillin came into clinical use. However, such strains occurred sporadically and were resistant only to -lactam antibiotics, causing no major problems. By contrast, the resistant strains that appeared in Australia in the late 1970s were entirely different; they were resistant to other types of ...

To investigate the effect of surgical treatment of hydrosalpinx on the expressions of estrogen receptor (ER) and progesterone receptor (PR) in the endometrium in implantation window, a total of 60 patients with hydrosalpinx and 30 patients with fallopian tube obstruction were recruited. In the implantation window, immnohistochemistry was carried out to detect the expressions of ER and PR in the...

The incidence of motion sickness in a large (N = 3,618) college population was determined by means of a questionnaire. Significantly greater proportions of men than women had low susceptibility scores; significantly greater proportions of women had high susceptibility scores. Comparisons of MSQ scores were made with other selfassessments, age changes, motion experiences, familial susceptibility...

The use of unstructured mesh codes on parallel machines can be one of the most e cient ways to solve large Computational Fluid Dynamics (CFD) and Computational Mechanics (CM) problems. Completely general geometries and complex behaviour can readily be modelled and, in principle, the inherent sparsity of many such problems can be exploited to obtain excellent parallel e ciencies. An important co...

The Repository, a collection of over 2000 technical papers and documents relating to computer science and engineering, is maintained by the Computer Society as a service to the information processing community. Some of the papers have been refereed,others have not. If you have a paper of interest to the computer field, you are invited to submit two copies, including abstract and
