    The great book of the Bible that fits best into the union movement of the Church is the book of Ephesians. This book deals first of all with the thought of Christian unity Since the Race Relations problem is primarily one of unity, as will be proved in the second chapter of this thesis, and since we are in the union period of the Church, much can be learned on the Race Relations problem for our day from the book of Ephesians

    A nickel electrostatic curved beam actuator for valve applications

    AbstractIn this contribution an electrostatic curved beam actuator for microvalve applications is presented. The actuator consists of two layers of nickel consequently plated upon each other. The resulting double-layer cantilever beam has internal stress gradient due to variation of the electroplating process parameters for each layer. By accurate control of these parameters, desired bending heights were obtained. Compared to bimetallic bending actuators, the curvature of the single-metal beam is less dependable on ambient temperature. Thus, more stable performance under changing working conditions was ensured. In order to avoid sticking during the operation of the variable capacitor, stand-off bumps on the back-side of the actuator beam were provided. The actuator was integrated into an active 2/2-microvalve on a silicon substrate

    Local existence of dynamical and trapping horizons

    Given a spacelike foliation of a spacetime and a marginally outer trapped surface S on some initial leaf, we prove that under a suitable stability condition S is contained in a ``horizon'', i.e. a smooth 3-surface foliated by marginally outer trapped slices which lie in the leaves of the given foliation. We also show that under rather weak energy conditions this horizon must be either achronal or spacelike everywhere. Furthermore, we discuss the relation between ``bounding'' and ``stability'' properties of marginally outer trapped surfaces.Comment: 4 pages, 1 figure, minor change

    <p>Abstract</p> <p>Background</p> <p>Cortical excitability changes as well as imbalances in excitatory and inhibitory circuits play a distinct pathophysiological role in chronic tinnitus. Repetitive transcranial magnetic stimulation (rTMS) over the temporoparietal cortex was recently introduced to modulate tinnitus perception. In the current study, the effect of theta-burst stimulation (TBS), a novel rTMS paradigm was investigated in chronic tinnitus. Twenty patients with chronic tinnitus completed the study. Tinnitus severity and loudness were monitored using a tinnitus questionnaire (TQ) and a visual analogue scale (VAS) before each session. Patients received 600 pulses of continuous TBS (cTBS), intermittent TBS (iTBS) and intermediate TBS (imTBS) over left inferior temporal cortex with an intensity of 80% of the individual active or resting motor threshold. Changes in subjective tinnitus perception were measured with a numerical rating scale (NRS).</p> <p>Results</p> <p>TBS applied to inferior temporal cortex appeared to be safe. Although half of the patients reported a slight attenuation of tinnitus perception, group analysis resulted in no significant difference when comparing the three specific types of TBS. Converting the NRS into the VAS allowed us to compare the time-course of aftereffects. Only cTBS resulted in a significant short-lasting improvement of the symptoms. In addition there was no significant difference when comparing the responder and non-responder groups regarding their anamnestic and audiological data. The TQ score correlated significantly with the VAS, lower loudness indicating less tinnitus distress.</p> <p>Conclusion</p> <p>TBS does not offer a promising outcome for patients with tinnitus in the presented study.</p

It provides an outline of the organizing institutions, detailing their individual perspectives on the general topic of the system-integrated intelligence. Furthermore, the editorial acknowledges the collective contribution of the program committees for the benefit of the successful scientific event

    A Community-Based Dental Program for Older Adults

    Full text link
    The planning and implementation of a community-based outreach program for older adults is described. Objectives of the program were to provide dental health education to older persons at their place of residence, to improve access to dental care for that population, and to increase the number of older adults treated at a dental facility administered by the Department of Community Dentistry, University of Michigan. Data collected during encounters with participants are reported to supplement the description of the program. In the first year, 98 older adults (mean age 71.3 years)participated in the outreach program which was directed by a dental hygienist. Of those persons whose initial encounter was with the outreach program, 47 percent eventually contacted the dental care facility and 36 percent completed treatment. Persons who elected to seek treatment averaged 3.9 encounters with the hygienist during the program; persons who did not seek treatment averaged 2.2 encounters. Strengths and weaknesses of the program are discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66221/1/j.1752-7325.1984.tb03075.x.pd
