Deep underground in Kolar Gold Fields, in southern India, an experiment to detect proton decay had been carried out since the end of 1980. Analysis of data yielded the following results; (l) the life time of proton is about 1 x 10 years, (2) it decays into wide spectrum of decay modes, p e , p K and so on, and (3) the life time and the distribution of decay modes are close to the predictions of...

Localized modes are analysed for a chain with nonlinear on-site potential using an approximation based on the discrete nonlinear Schr0dinger equation. It is pointed out that such localized modes exist in the parameter domains where the system displays modulational instability. Otherwise, nonlinear modes may appear in the form of dark-profile localized structures, and two types of such structure...

this study was investigated reproductive differences in fall and spring migrants of caspian lamprey (caspiomyzon wagneri) in the shirud river (southern caspian sea)in 2008. 89 and 15 specimens were sampled in in spring and fall, respectively. generally, fall migratory fish had a significantly lower condition factor (cf) compared to the spring migrants. there was significant relationship between...

STUDY DESIGN Gait analysis of patients with cervical spondylotic myelopathy (CSM) by using a sheet-type gait analysis system. PURPOSE The aim of this study was to compare the gait patterns of patients with CSM, evaluated by the Nurick grades, and to determine the threshold values of gait parameters predicting the occurrence of a fall by using a gait recorder. OVERVIEW OF LITERATURE Gait dis...

Parkinson's disease is a chronically developing neurodegenerative disease showing typical motor symptoms of the following triad: resting tremor, freezing of gait, and bradykinesia-hypokinesia. In the present study, we investigated the effects of a communal exercise program, using the visual and auditory feedback provided by a smart application, to assess gait ability, fear of falling, and fall ...

The purpose of this study is to investigate the effect of exercising program utilizing proprioceptive neuromuscular facilitation integration pattern (PIP), which is effective in improvement of the physical function, on the fall efficacy and gait ability of the elders who experienced injuries from falls. Also, this study aims to investigate he applicability of exercise program as methods for fal...

Slip training is gaining popularity as an innovative fall intervention approach. The objective of this study was to compare the efficacy of two different slip training modality (moveable platform and virtual reality) in reducing fall frequency and improving reactive recovery in older adults. Thirty-six healthy older adults were involved in a laboratory study, and were equally and randomly divid...

The second moment of the Hβ emission line is calculated for 329 narrow line Seyfert 1 galaxies (NLS1s) selected from the Sloan Digital Sky Survey (SDSS), which is used to calculate the central supermassive black hole (SMBHs) mass of each. We find that the second moment depends strongly on the broader component of the Hβ line profile. We find that for the NLS1s requiring two Gaussians to fit the...

We report experimental measurements of density waves in granular materials flowing down in a capillary tube. The density wave regime occurs at intermediate flow rates between a low density free fall regime and a high compactness slower flow. We observe this intermediate state when the ratio of the tube diameter and the particles size lies between 6 and 30. The propagation velocity of the waves ...

1. Twenty-seven young subjects used their right hand to perform sustained, isometric contractions at 40% of maximum for 2 min while lying supine. 2. During the last 30 s of exercise, mean arterial blood pressure increased by 38 +/- 4 mmHg (mean +/- S.E.M.) and heart rate by 27 +/- 2 beats/min. 3. Nineteen of the subjects respired eucapnically during exercise, increasing ventilation by 4.1 +/- 0...
