Background Psychiatric advance directives (PADs) provide a legal means for competent individuals to refuse or consent to future mental health treatment during periods of decisional incapacity. Previous studies have shown high potential demand for PADs but low rates of completion in the United States, despite new laws authorizing PADs in over 20 states. This paper reports the results of the firs...

The dynamical responses of railway track has been carried out by different ways. In this work, developing an analytical model for the ballasted which includes two rails connected to sleeper, a fast method calculated dynamic is presented. rail modelled as infinite beams posed on periodically supports are rested viscoelastic foundation. We consider equation in steady-state subjected moving loads....

To study the mechanical characteristics of ballasted bed under dynamic stability, a three-dimensional discrete element model with 1000 mm × 700 550 is established based on method. Meanwhile, simulation test bench same size built for analysis and experimental research. The variation law trend settlement, lateral resistance, compactness different excitation frequencies are analyzed comprehensivel...

Primary antibody deficiencies (PAD) are a group of immune system disorders, associated with decreased levels of secretory and protective immunoglobulins. Because of the important role of immunoglobulins in the protection of oral cavity, patients with PADs are more susceptible to dental caries or oral manifestations. This study was performed to investigate the oral and dental manifestations of P...

This research was conducted to replicate and expanded the work of Bodfish et al. [Bodfish, J. W., Harper, V. N., Deacon, J. R., & Symons, F. J. (2001, May). Identifying and measuring pain in persons with developmental disabilities: A manual for the Pain and Discomfort Scale (PADS). Western Carolina Center Research Reports] by assessing the functional sensitivity of the Pain and Discomfort Scale...

To save layout area for electrostatic discharge (ESD) protection design in the SOC era, test chip with large size NMOS devices placed under bond pads has been fabricated in 0.35-μm one-poly-four-metal (1P4M) 3.3V CMOS process for verification. The bond pads had been drawn with different layout patterns on the inter-layer metals to investigate the effect of bonding stress on the active devices u...

The saccule is known to play an important role in hearing in fishes. In this study we investigated spatial frequency selectivity of single saccular afferents in a teleost fish (the sleeper goby, Dormitator latifrons) to acoustic particle motion at 50-400 Hz. Saccular afferents have similar distributions of best sensitivity (-90.0 to -54.8 dB re. 1 g, mean +/- s.d.=-81.1+/-8.0 dB) and characteri...

An analysis of group influence processes indicates that the functional relationship between attraction to a group and influence exerted by the group depends on the importance to the individual member of any freedom that is threatened by group pressure to conform. This proposition was tested by an experiment in which the effect of group conformity pressure on public and private opinions was meas...

in this paper, the main factors in the analysis of the railway concrete sleepers areinvestigated and new recommendations are made in order to improve the accuracy of the currentpractices in analysis of the railway track system. first, a comprehensive literature survey isconducted, then, fem models for a railway track system are developed and used to discuss andevaluate the assumptions commonly ...

Many stick insects and mantophasmids possess tarsal 'heel pads' (euplantulae) covered by arrays of conical, micrometre-sized hairs (acanthae). These pads are used mainly under compression; they respond to load with increasing shear resistance, and show negligible adhesion. Reflected-light microscopy in stick insects (Carausius morosus) revealed that the contact area of 'heel pads' changes with ...
