The affected pig should be restrained and the corrugated tube gently inserted into the lumen of the prolapsed rectum the halfway-point on the tube needs to be inserted as far as the anal sphincter. The rubber bands should be stretched over the prolapse and placed as near as possible to the perianal skin; they must be tight enough to stop the blood supply to the prolapse. Faeces may move down th...
This paper deals with single layer Frequency selective surface (FSS) which acts as a double band reject filter. The two stop bands are really broad with percentage bandwidth of 26.67% and 14.53%. The maximum and minimum band separation for this proposed design is around 45 dB and frequency ratio is more than 1.9.This results are almost same for different incident angles.. This design is investi...
In this longitudinal study, the authors compared 1,244 white- and blue-collar workers who reported 0, 1, or 2 contacts with layoffs; all were employees of a large manufacturing company that had engaged in several mass waves of downsizing. Consistent with a stress-vulnerability model, workers with a greater number of exposures to both direct and indirect downsizing reported significantly lower l...
Employees (N = 194) from a wide variety of organizations participated in this study aimed at describing the attitudes of individuals who refuse to respond to an employee survey request (noncompliants). Noncompliants, in comparison with those individuals who would comply with the survey request, possessed greater intentions to quit, less organizational commitment, and less satisfaction toward su...
This study assessed the acoustic and perceptual effect of noise on vowel and stop-consonant spectra. Multi-talker babble and speech-shaped noise were added to vowel and stop stimuli at -5 to +10 dB S/N, and the effect of noise was quantified in terms of (a) spectral envelope differences between the noisy and clean spectra in three frequency bands, (b) presence of reliable F1 and F2 information ...
A novel compact size ultrawide band planar antenna with notched characteristics is present. The rejection characteristic achieved by loading a pair of metamaterial inspired rectangular split ring resonator (SRR) near the feed line and etching SRR slots on radiating patch. simulated measured results reveal that proposed exhibits impedance bandwidth over (UWB) frequency range from 3.1 to 14 GHz v...
A solution methodology for the design of digital infinite impulse response (IIR) filter considering multiple conflicting objectives has been proposed. The nucleus of the method is that multiple objectives can be attuned suitably, to optimize the performance in pass bands, stop bands and transition bands of IIR digital filters. The proposed method uses multiobjective optimization approach for de...
