1. Latency behavior of neurons in the cochlear nuclear complex was studied in 45 barbiturate-anesthetized cats. Stimuli were tonal bursts usually 50-500 ms in duration. 2. Latency of the initial discharge is a systematic function of the frequency and intensity of the tone for a large class of neurons which are termed latency precedence cells. Most cells in the anteroventral cochlear nucleus and...

This study examined, in nine old men (82 +/- 4 yr), whether there is an association between the magnitude of change in motor unit discharge rate and the amount of twitch potentiation after a conditioning contraction (CC). The evoked twitch force and motor unit discharge rate during isometric ramp-and-hold contractions (10-18 s) of the triceps brachii muscle at 10, 20, and 30% of the maximal vol...

There has been increasing attention paid to small area variation in hospital discharge rates. While there is general agreement about the importance of correcting for the migration of patients to hospitals outside their geographic area when constructing population-based hospital use rates for these small areas, there have been no studies of the sensitivity of simple correlations or multiple regr...

the treatment of thyroid cancer using an unsealed source of radioactive materials is usually associated with a large amount of 131i. a major problem for hospital admission of these patients is the waste disposal which requires protection of the public. 152 patients with thyroid cancer admitted to the nuclear medicine department of said ai- shohada hospital for ui i treatment were studied. 1311 ...

Floating emissive probe plasma potential data are presented over a two-dimensional array of locations in the discharge chamber of a 40-cm diameter ring-cusp ion thruster. The data rule out the presence of a potential-hill plasma structure downstream of the discharge cathode assembly (DCA), which has been proposed as a mechanism of high-energy ion formation leading to DCA erosion. The discharge ...

In order to investigate the behavioral role of pontine gigantocellular field (FTG) units, we have operantly reinforced discharge in these cells in unrestrained cats using lateral hypothalamic stimulation as the reinforcing stimulus. Cats readily learned to increase discharge rate in reinforced FTG cells relative to simultaneously recorded, non-reinforced control cells. Increased FTG discharge w...

abstract prediction of input flow into water resources is regarded as one of the most important issues in optimum planning and management in producing electro-water energy and optimum allocation of water into different consumption sources. different parameters affect on input discharge into dams. climate variables including temperature and rainfall have the most effect on input runoff rate to w...

Background Patent ductus arteriosus is an open channel between the aorta and pulmonary artery. The study aimed to evaluate the clinical course of patent ductus arteriosus after discharge and comparing in therapies technique. Materials and Methods This cross-sectional and inferential- descriptive study was performed in the hospitals of city of Zahedan-Iran in the period of one decade from 2005 ...

We validate that the 28 days after hospital-discharge are high-risk for drugs-related death (DRD) among drug users in Scotland and investigate key risk-factors for DRDs soon after hospital-discharge. Using data from an anonymous linkage of hospitalisation and death records to the Scottish Drugs Misuse Database (SDMD), including over 98,000 individuals registered for drug treatment during 1 Apri...
