Published 1990Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: The multiphoton decomposition (MPD) of chloroform-d, CDCl3, with a pulsed 13CO2 infrared laser is reported. A new method is developed that takes into account the effect of the number of pulses required to obtain a measurable decomposition. This method relies on difference equations and replaces current methods based on differential calculus. The rate equation language of the latter is shown to be inappropriate. The decomposition probability is measured at constant fluence up to a pressure of 2 kPa and empirical representations of the pressure dependence of the MPD are reported. A collision-dependent reaction scheme is presented to explain the pressure dependence of the up-pumping through the vibrational manifold.Type of Medium: Electronic ResourceURL: -

Published 1993Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Epitaxial C60 films grown by molecular beam deposition onto CaF2(111) surfaces are investigated by reflection high-energy electron diffraction at deposition temperatures of 30–300 °C and coverages corresponding to average thicknesses of 1–50 nm. Over this entire temperature range, C60 forms an incommensurate overgrowth of stacked hexagonal layers exhibiting a characteristic nearest-neighbor spacing of 0.98 nm. Below 170 °C, unidirectional growth occurs in accordance with the crystallographic directions of the substrate. At higher deposition temperatures, however, two equivalent, rotated domain orientations are observed which are characterized by a significantly lower degree of lattice mismatch.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: A three-dimensional, static mathematical calculation of the stomatognathic system was done to predict total temporomandibular joint (TMJ) loading at different levels of jaw opening. The model assumed that muscle forces acting on the mandible could be simulated by a combination of contractile components (CCs) and elastic components (ECs) and that static equilibrium existed within the body of the mandible. The model also imposed the constraint that any generated joint reaction force would act on the centre of the condyle. The results of the model demonstrated that under all conditions of opening and for all values of the elastic modulus selected, the forces between the TMJ condyle and the articular eminence were compressive in nature. The compressive force magnitude increased from 2·7 to 27·6 N incrementally as the jaw opened from 10 to 40 mm. Overall data in this study indicated that the TMJ tissues undergo low levels of compression at open positions up to 40 mm. Finally, the condition of trismus (increased jaw closing activation with opening) was simulated, the joint reaction force at 20 mm opening increased from 7·7 to 64·9 N with only a 20% activation of the closers.Type of Medium: Electronic ResourceURL: -

Published 1999Staff ViewISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: This study aimed (1) to investigate the influences of sex, age and number of teeth on biting ability through a descriptive survey, and (2) to compare the biting ability between the subjects with and without mobile teeth in a case-control study. A total of 687 subjects cooperated in the descriptive survey. Each subject bit on a pressure detecting sheet with their maximum biting force. Three indices of biting ability: biting pressure (MPa), biting force (N) and occlusal contact area (mm2) were calculated from the impressed marks on the sheet using a high vision video processor system. These indices were correlated well with the number of teeth according to the multiple regression analysis. In the case-control study, matching procedures with sex, age and number of teeth were performed between the subjects with and without mobile teeth. No differences in the three indices were observed between the two well-balanced groups. The results showed that the number of teeth is most important to maintain biting ability, and that the presence of mobile teeth does not always reduce biting ability.Type of Medium: Electronic ResourceURL: -

Published 1998Staff ViewISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: The purpose of this study was to investigate the relationship between osseous changes in the temporomandibular joint (TMJ) and dental attrition in the Japanese macaque. One hundred and thirty Japanese macaque skulls (54 male and 76 female) from animals which had been bred in the same environment, were randomly sampled from a collection at the Primate Research Institute of Kyoto University. The age at death had been recorded in all cases. TMJ osseous changes were independently evaluated by three examiners, and were defined as an irregular surface or a perforated compact bone layer with a markedly irregular surface on either the temporal or condylar components. Age was a significant factor in predicting TMJ osseous changes (P 〈 0·001). A strong relation was observed between age and dental attrition (P 〈 0·001), while dental attrition was not a significant factor in predicting TMJ osseous changes (P = 0·334). The prevalence TMJ osseous changes in male animals was slightly higher than in females (P = 0·057). The results of this study suggest that osseous changes in the macaque TMJ are mainly related to age, not to dental attrition.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: This study investigated the masticatory rehabilitation of subjects wearing different types of prostheses. Biting abilities per person (biting force, biting pressure and occlusal contact area) were assessed with a pressure detecting sheet (Prescale®). Five hundred and ninety volunteers were divided into four groups according to the type of posterior dentition: complete denture, removable partial denture, fixed partial denture, and full natural dentition groups. The biting forces of the fixed partial, removable partial and complete denture wearers were 80, 35 and 11% respectively, when expressed as a percentage of the subjects with a natural dentition. The complete denture wearers showed the highest biting pressure among the four groups, followed by the removable partial denture wearers. In a clinical intra-individual study, the biting abilities of 85 subjects, without (before insertion of) and with (after insertion of) renewed prostheses, were compared. No significant differences were found between biting before and immediately after insertion of the prostheses. However, the biting force and occlusal contact area increased 2 months after insertion of the prostheses. This study confirmed past clinical studies indicating an impaired masticatory function of denture wearers. The functional adaptation to new prostheses had improved at evaluation 2 months after insertion.Type of Medium: Electronic ResourceURL: -
