Prosthetic Management of Edentulous Mandible using Endosseous Implants and Overdentures
No full textABSTRACT
The choice of a suitable prosthesis for a specific case is determined to a great extent by the underlying residual bone as well as the mucosa. Also of significance are the expectations and demands of the patient from the prosthesis. The following case report discusses the rehabilitation of a complete edentulous mandibular arch with an implant retained mandibular over denture.
Clinical Significance
Implant retained fixed or removable prostheses are good treatment options in patients who have a compromised edentulous foundation.

Elastic-plastic characterization of microstructures through pull-in 4 point bending test
No full textThis paper presents a simple design of gold MEMS, with a central test specimen undergoing tensile loading, for the experimental characterization of elastic–plastic behavior using electrostatic actuation. A kinematic model for the test microstructures is presented that relates the experimentally measured deflection in the test specimen to the developed axial and bending stress. Moreover, an elastic–plastic beam bending model is presented to analyze the development of plastic hinges in the central test specimen. The design of test microstructures allows us to achieve stress values higher than the yield stress of the gold specimen before the pull-in effect, thus allowing to analyze the effect of elastic–plastic behavior on the static deflection profile of the central test specimen under repeated loading. The actuation voltage-deflection tests under repeated loading, both in the elastic and elastic–plastic region, allowed to estimate the applied stress limit for the onset of plasticity in gold thin film based MEMS devices

Employee emotional competence and service recovery satisfaction: the mediating role of consumer forgiveness
No full textPurpose: Employees' emotional competence (EEC) is gaining increasing attention in service failure and recovery research. This study investigates the mediating role of consumer forgiveness between perceived EEC and recovery satisfaction among casual dining consumers. Additionally, this study examines the effect of perceived EEC on recovery satisfaction across process failure vs outcome failure. Design/methodology/approach: A critical incident technique (CIT) in conjunction with a self-administered online survey was carried out. Using the snowball sampling technique, a total of 204 useable responses were collected. To test the hypotheses, this study used partial least squares structural equation modeling (PLS-SEM). Findings: The study finds that perceived EEC influences service recovery satisfaction. Additionally, the study identifies the mediating role of consumer forgiveness in the relationship between perceived EEC and recovery satisfaction. Multi-group moderation analysis shows that the relationship between perceived EEC and recovery satisfaction is weaker in process failures as compared to outcome failures. Practical implications: Based on obtained results, this study recommends that after service failure consumer forgiveness and subsequent recovery satisfaction can be obtained with perceived EEC. To do so, managers need to incorporate emotional competence while recruiting and training the employees. Moreover, managers need to train employees on failure types and respective recovery strategies. Lastly, the study suggests that in emerging markets managers should pay greater emphasis on process failure, because such failure decreases customer satisfaction greatly than outcome failure. Originality/value: To the authors' knowledge, this is the first study that investigates the impact of perceived EEC on consumer forgiveness which subsequently determines the recovery satisfaction in the emerging markets. It extends the application of the emotional contagion and affect infusion theories by exposing the effect of perceived EEC on recovery satisfaction through consumer forgiveness. In addition, the study provides insights that the influence of perceived ECC on recovery satisfaction significantly varies across service failure types
A dual-mass resonant mems gyroscope design with electrostatic tuning for frequency mismatch compensation
No full textThe micro-electro-mechanical systems (MEMS)-based sensor technologies are considered to be the enabling factor for the future development of smart sensing applications, mainly due to their small size, low power consumption and relatively low cost. This paper presents a new structurally and thermally stable design of a resonant mode-matched electrostatic z-axis MEMS gyroscope considering the foundry constraints of relatively low cost and commercially available silicon-on-insulator multi-user MEMS processes (SOIMUMPs) microfabrication process. The novelty of the proposed MEMS gyroscope design lies in the implementation of two separate masses for the drive and sense axis using a unique mechanical spring configuration that allows minimizing the cross-axis coupling between the drive and sense modes. For frequency mismatch compensation between the drive and sense modes due to foundry process uncertainties and gyroscope operating temperature variations, a comb-drive-based electrostatic tuning is implemented in the proposed design. The performance of the MEMS gyroscope design is verified through a detailed coupled-field electric-structural-thermal finite element method (FEM)-based analysis
Study of notched MEMS specimen: Elasto-plastic modeling and experimental testing
No full textThis paper investigates the effect of stress and strains concentration, due to the notch presence, on the elasto-plastic behavior of gold microstructures subjected to tensile loading under electrostatic actuation. A kinematic model for the test microstructure which relates the experimentally measured deflection to the induced stress in the central specimen with applied electrostatic load is developed. The local maximum stress and strains at the notch root are analytically estimated using the Neuber's rule and verified through a detailed non-linear coupled-field electric-structural finite element method (FEM)-based analysis. Several experimental tests are carried out to analyze the accumulation of plastic strain and the consequent development of plastic hinges induced in the central notched specimen due to repeated cyclic tensile loading by measuring the corresponding deflection with each loading cycle. The comparison between the failure condition observed experimentally in the test notched specimens and the FEM-based simulation results shows that the notch acts as stress and strains raiser fostering the initiation and expansion of plastic hinges in the thin film gold specimen which can lead to the specimen breakdown
Knox-Saleem kinetic performance limits in liquid chromatography—A contemporary tutorial
No full textThe kinetic performance limits evaluated by Knox and Saleem in 1969 are reevaluated herein. Published 55 years ago, the original study did not address several key features of contemporary chromatography. The following features of chromatographic analyses were assumed in the source: • The static operations (isothermal isobaric GC, isocratic isothermal isobaric LC). • The columns packed with discrete particles. • The columns were optimized to deliver the smallest plate height.Additionally, currently obsolete parameters and notations were used complicating comprehension of the original study.In this tutorial focusing mostly on LC, the original Knox-Saleem study is extended to gradient elution LC, to the columns with arbitrary structure (open, packed, pillar array, monolithic, etc.) and to suboptimal operations – all expressed in contemporary notations. The study is based on previously published basic structure-independent equations of column kinetic performance.Some conclusions of this tutorial are different from previous ones. It has been concluded herein that at any pressure (no matter how low) any separation performance (no matter how high) can be achieved as long as the analysis time is acceptable. This seems to contradict with Knox-Saleem statement suggesting that there is “the critical pressure below which a separation number S cannot be achieved however much time is available.” Similar statement was also previously known from Giddings (1962): “critical pressure, pc, the inlet pressure below which a [required, LB] separation can never be obtained”
