Krakow’s threads of family life of Stanisław Wysocki (1805-1868) – designer and constructor of the Warsaw-Vienna Railroad
No full textPostacią pierwszej wielkości, mającą niewątpliwe zasługi w dziedzinie projektowania i budowy linii kolejowych jest Stanisław Wysocki (1805-1868) – projektant i budowniczy Drogi Żelaznej Warszawsko-Wiedeńskiej, pierwszej europejskiej magistrali kolejowej. Wspomnienie związane jest z jubileuszem 170 lat kolei w Krakowie, bo właśnie z tym miastem są związane losy jego rodziny.The significant figure, who undoubtedly contributed in the field of designing and devoloping railway lines is Stanisław Wysocki (1805-1868) - designer and constructor of the Warsaw-Vienna Railroad, the first European trunk railway line. The memoir is related to the jubilee of 170 years of railways in Krakow, because it is with this city that the history of his family is connected

Sound pressure and particle acceleration audiograms in three marine fish species from the Adriatic Sea
No full textFishes show great variability in hearing sensitivity, bandwidth, and the appropriate stimulus component for the inner ear (particle motion or pressure). Here, hearing sensitivities in three vocal marine species belonging to different families were described in terms of sound pressure and particle acceleration. In particular, hearing sensitivity to tone bursts of varying frequencies were measured in the red-mouthed goby Gobius cruentatus, the Mediterranean damselfish Chromis chromis, and the brown meagre Sciaena umbra using the non-invasive auditory evoked potential-recording technique. Hearing thresholds were measured in terms of sound pressure level and particle acceleration level in the three Cartesian directions using a newly developed miniature pressure-acceleration sensor. The brown meagre showed the broadest hearing range (up to 3000 Hz) and the best hearing sensitivity, both in terms of sound pressure and particle acceleration. The red-mouthed goby and the damselfish were less sensitive, with upper frequency limits of 700 and 600 Hz, respectively. The low auditory thresholds and the large hearing bandwidth of S. umbra indicate that sound pressure may play a role in S. umbra's hearing, even though pronounced connections between the swim bladder and the inner ears are lacking. © 2009 Acoustical Society of America

Effects of ambient and boat noise on hearing and communication in three fish species living in a marine protected area (Miramare, Italy)
No full textThe WWF-Natural Marine Reserve of Miramare (Trieste, Italy) is located in a major industrial and vacation area in the Adriatic Sea. Consequently, noise emanating from boating and shipping is an inevitable factor for local fishes. This study investigates the effects of ambient and ship noise on representatives of three vocal fish families with different hearing abilities. Ambient and ship noise were recorded, their sound pressure levels measured and played back in the lab. Auditory sensitivity was determined in Chromis chromis, Sciaena umbra and Gobius cruentatus, utilizing the auditory evoked potential recording technique. Compared to lab conditions, hearing thresholds determined during ambient noise playbacks were barely masked. Contrary, the noise emanating from a cabin-cruiser substantially reduced auditory sensitivity relative to thresholds in ambient noise. This masking effect was most pronounced in the frequency range where acoustic communication takes place. Boat noise potentially affects acoustic communication in fishes inhabiting the reserve. © 2009 Elsevier Ltd. All rights reserved
Tuning properties of mid-infrared Fabry-Pérot quantum cascade lasers for multiheterodyne spectroscopy
No full textInjection current tuning properties of an 8.5 um Fabry-Pérot mid-infrared quantum cascade laser are evaluated by analyzing the mode-by-mode frequency tuning behavior with an identification of high-noise regimes in a delayed self-heterodyne experiment. We find that modes on the edges of the spectral envelope exhibit anomalous tuning coefficients compared to those in the center. Furthermore, the frequencies of individual modes are susceptible to parasitic etalons, likely causing laser frequency pulling. Despite the complicated tuning behavior, low phase-noise operating regimes exist, and are compatible with high resolution multiheterodyne spectroscopy of gases. Full Text: PDF ReferencesJ. Faist, F.
