Deep-Water Tardigrada of the Istanbul Strait’S (Bosporus) Outlet Area of the Black Sea

The results of investigations of tardigrades (2009-2010) in the Bosporus outlet area of the Black Sea are represented. For the first time two species of tardigrades Dipodarctus subterraneus (Renaud-Debyser, 1959) and Tanarctus ramazzottii (Renaud-Mornant, 1975) are recorded for the Black Sea. Tardigrades are registered on 4 stations at depths range 88-250 m. Average abundance of tardigrades widely varied from 141 to 11 440 ind./m². The vertical distribution of tardigrades in the sediments was analyzed: most specimens (up to 98 %) found in the top 0-1 cm sediment layer.Приведены результаты исследований тихоходок (2009-2010 гг.) в Прибосфорском районе (Чёрное море). Впервые для Чёрного моря зарегистрированы два вида тихоходок Dipodarctus subterraneus (Renaud-Debyser, 1959) и Tanarctus ramazzottii (Renaud-Mornant, 1975). Тихоходки были зарегистрированы на 4 станциях в диапазоне глубин 88-250 м. Средняя численность тихоходок варьировала в широких пределах от 141 до 11 440 экз./м². Проанализировано вертикальное распределение тихоходок в донных осадках: большинство экземпляров (до 98 %) обнаружены в верхнем 0-1 см слое донных осадков

Optimal code sequences in problems of clock synchronization of communication systems with noise signal phase-shift keying

This study deals with a new method proposed for the clock synchronization of communication systems with noise signal phase-shift keying. The developed method is based on using a special linear transformation of the information part of signal in the transmitter and of the reference part of signal in the receiver. It has been shown that transformations with required properties can be obtained on the basis of optimal code sequences

Musical Elicitation Methods

Music is an underutilized resource for research in the social sciences. This article presents examples of musical elicitation methods that were used within a study that explored how adolescents who were referred to group music therapy for aggression produced meanings of aggression through the therapeutic process. The study was conducted within a poststructuralist paradigm, particularly using the theoretical thinking tools of Deleuze and Gergen. The elicitation methods discussed include drumming, creating images during music listening, and songwriting. The article argues for the role of musical elicitation methods particularly within research that values a radical relational stance that allows participants to comfortably territorialize the research encounter, and in light of considering the transformative potential of research itself
