The Relationship

This report describes an unusual and persistent dysphonia in two young women who had taken a therapeutic regimen of isotretinoin for intractable acne. We report perceptual and instrumental data for their dysphonia, and pose a theoretical basis for the relationship of dysphonia to this drug. We also provide recommendations for reducing the risk of acquiring a dysphonia during the course of treatment with isotretinoin.

AbstractScottish Gaelic is sometimes described as having nasalized fricatives (/ṽ/ distinctively, and [f̃, x̃, h̃], etc. through assimilation). However, there are claims that it is not aerodynamically possible to open the velum for nasalization while maintaining frication noise. We present aerodynamic data from 14 native Scottish Gaelic speakers to determine how the posited nasalized fricatives in this language are realized. Most tokens demonstrate loss of nasalization, but nasalization does occur in some contexts without aerodynamic conflict, e.g., nasalization with the consonant realized as an approximant, nasalization of [h̃], nasalization on the preceding vowel, or sequential frication and nasalization. Furthermore, a very few tokens do contain simultaneous nasalization and frication with a trade-off in airflow. We also present perceptual evidence showing that Gaelic listeners can hear this distinction slightly better than chance. Thus, instrumental data from one of the few languages in the world described as having nasalized fricatives confirms that the claimed sounds are not made by producing strong nasalization concurrently with clear frication noise. Furthermore, although speakers most often neutralize the nasalization, when they maintain it, they do so through a variety of phonetic mechanisms, even within a single language.

The Town

Abstract. At 07:00 h (UTC-6) on 22 June 1932, a Ms = 6.9 earthquake shocked the coasts of Colima and Jalisco. Five minutes later a tsunami arrived at the coast. It almost completely destroyed the town of Cuyutlán, Colima, causing the deaths of 50 people and leaving about 1200 injured. In this study, newspaper reports and technical reports are reviewed, as well as survivors' testimonials. The physical characteristics (mean sea level at the time, time of arrival, sea retreat, and inundation distribution) and the tsunami effects (number of victims, injuries, affected buildings) have been reconstructed and mapped. The interpretation of historical data allowed us to determine the intensity of the tsunami and to reveal the tsunamigenic source. This study emphasizes the relevance of historical analysis, including survivor's testimonies, in the reconstruction of tsunamis that lack instrumental data. The results of this study are relevant to paleotsunami studies and tsunami related hazard planning.

<p><strong>Aim:</strong> This pilot study is designed to better understand the mechanisms of development and control of atrial fibrillation.<br /><strong>Methods:</strong> The correlation between fibrosis index (FI), which was calculated intraoperatively with special software, and clinical and instrumental data was analyzed. Also evaluated were FI values as compared to AF catheter ablation outcomes. <br /><strong>Results:</strong> Voltage mapping may be considered as a possible alternative to MRI examination and in some cases it is more informative. <br /><strong>Conclusion:</strong> It was found out that the preliminary results received are a good start for planning a large-scale study in this area related to assessment of the predicative and practical value of the fibrosis index.</p>
