Abstract

The new bread wheat cultivar Sids 13 has been developed by Wheat Research Department, Field Crops Research Institute, Agriculture Research Center, Egypt and selected from one of the advanced lines among ICARDA collections grown in wheat breeding program at Sids Agricultural Research Station. The grain yield of the new cultivar Sids 13 was evaluated through 66 experiments at two different levels of yield trials (11 preliminary and 55 advanced yield trials) in the three successive seasons 2004/2005, 2005/2006 and 2006/2007, respectively. The obtained results proved the superiority of the new cultivar Sids 13 as compared to the local commercial cultivars, Giza 168, Sakha 93 and Gemmiza 9 in the main five regions of Egypt, i.e. North Delta, South Delta, Middle Egypt, Upper Egypt and Out Valley. Moreover, stability parameters for grain yield cleared that the newly bread wheat cultivar Sids 13 has better stability parameters in both South Delta and Upper Egypt regions and could be recommended for planting in those regions. Also, the results of rust diseases reactions proved that Sids 13 has high resistance to all tested pathotypes of the three rust diseases under local conditions.

Abstract

The effect of a new digital hearing aid (Beltone-Lumina D71HP) with noise suppression was evaluated in comparison to analog hearing aids. The study comprised of 10 patients that were wearing the instruments for two periods of 1 month. For one period, the noise-suppression system was switched on and switched off for the other period in random order. The performance was evaluated by speech in noise tests (SPIN tests) and by the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire. Results showed significant improvements compared to analog instruments. The effect of the noise-suppression system on speech understanding in noise was small, but the positive effect was confirmed by the APHAB questionnaire for the background noise (BN) category.

Abstract

Objective: We aims to detect the efficacy of directional microphone when combined with noise reduction algorithm in improving speech intelligibility in noisy environments for hearing impaired subjects. Materials and Methods: Twenty adult subjects with bilateral symmetrical sensory neural hearing loss of moderate to moderately severe degree were examined. Aided assessment was done in two settings using BTE digital hearing aid. First setting included: evaluation using noise reduction algorithm alone. Evaluation in the second setting was done using both noise reduction algorithm and directional microphone. Aided evaluation consisted of speech discrimination scores in quiet and speech in noise test in different noise scenarios. Just follow conversation test was done to detect the least signal to noise ratio a subject can tolerate in each of the two settings. The subjective impression of the patient was assessed by a modified questionnaire for hearing aid assessment. Results: Investigation showed statistically significant improvement of aided speech discrimination scores in noise in the second aided setting when speech was at zero degree azimuths and noise was at zero and 180 degrees azimuth. Conclusion: Directional microphone when combined with noise reduction algorithm in a digital hearing aid, adds benefit in improving speech intelligibility for patients with moderately-severe sensory neural hearing loss whatever the duration of the hearing loss.
