Face validity in animal models of alcohol abuse and dependence is often at odds with robust demonstrations of ethanol-seeking. This study determined the relative influence of ethanol and a flavorant in maintaining ethanol intake in a nonhuman primate model of "cocktail" drinking. Four-year-old male monkeys were maintained on a 6% ethanol/6% Tang solution made available in daily (M-F) 1-h sessio...
A symmetric Key-Distribution Center is a trusted server that knows each user's password. The KDC issues temporary session-keys to users who know their passwords. Each user's initial session-key comes to him under his password's encryption. The KDC then uses this initial key to encrypt the user's subsequent session keys. 1. Account-Creation: The user proves his identity to the KDC's administrato...
BACKGROUND The purpose of this study was to assess the repeatability and limits of agreement of corneal thickness values measured by a high-frequency ultrasound (Artemis-2), hand-held ultrasound pachymeter (DGH-500) and a specular microscope (SP-3000P). METHODS Central corneal thickness (CCT) was analyzed in this prospective randomized study that included 32 patients (18 men and 14 women) age...
In this paper, we describe a paradigm and its associated collaboration artifact to allow exible support for asynchronous collaboration. Under this paradigm, a user session with an application's user interface is encapsulated into a data artifact, referred to as a session object. Users collaborate by annotating, by modifying, and by a back-and-forth exchange of these session objects. Each sessio...
results both counterforce straps were effective. however, significantly more improvement was observed in pain and grip strength after using the newly modified orthosis (p < 0.05). conclusions the newly designed strap reduces pain more effectively and improves grip strength by causing greater localized pressure on two regions with different force applications (two component vectors versus one). ...
Estimating the network delays between each pair of nodes in a multicast session is the key parameter in reliable multicast; it is used, among other things, in suppressing the implosion of request and repair packets, and in detecting congestion. Existing implementations useO(n) multicasts withO(n) message size each (total of O(n) bits); here, n is the session size. We present a new protocol that...
In our standard geodetic VLBI solutions, we estimate the positions of quasars assuming that their positions do not vary in time. However, in solutions estimating proper motion, a significant number of quasars show apparent proper motion greater than 50 μas/yr. For individual quasars, there are source structure effects that cause apparent proper motion. To examine how coherent the pattern of app...
The purpose of this preliminary study was to examine the effects of the Transcendental Meditation program on learning ability and retention (acquisition and recall). The experiment was composed of three sessions of paired-associate anticipation learning and recall, each spaced one week apart. Ten subjects who were experienced with the Transcendental Meditation technique (mean experience = 28 mo...
The purpose of this study was to examine the physiological and psychological responses to a university fitness session entitled 'popmobility'. A popmobility session consists of 20 min of aerobic activities, 5 min of local muscular endurance exercises and 5 min of flexibility exercises. Ten regular participants of these sessions, women of mean(s.d.) age 21.2(1.5) years, took part in the study. A...
