Konotacje nazw barw w toponimii i hydronimii śląskiej (czarny, biały, zielony)
2021
Kolory należą do podstawowych środków orientacji człowieka w świecie. Niosą informacje o wartościach wyznawanych przez dane społeczeństwo, są wyrazem tożsamości jednostkowej i zbiorowej, wywołują różne skojarzenia i emocje, odzwierciedlają sposób postrzegania otaczającej rzeczywistości. Przedmiotem artykułu są nazwy geograficzne Śląska zawierające element kolorystyczny: czarny, biały i zielony – najbardziej charakterystyczne barwy Śląska. Badaniu zostały poddane zarówno nazwy genetycznie polskie, jak i niemieckie, gdyż historia Śląska i naturalna symbioza językowo-kulturowa pozwalają traktować je na równi. Badania nazw kolorów w obu językach nie wykazują też większych różnic w konotacjach i…
A social survey on the effects of environmental noise on the residents of Pamplona, Spain
1998
Abstract An extensive noise survey carried out in the city of Pamplona, Spain over 2 years has allowed us to elaborate a detailed daytime acoustic map of this city. The degree of noise annoyance in the community and its relationship with the measured noise levels has also been studied by means of a social survey.
Acoustic spectroscopy of aerogel precursors
2007
We investigate the acoustical properties of silica gels, which are precursors in the aerogel production process. These gels exhibit a strong “ringing gel” behavior, that is they emit a characteristic sound if one knocks against the container. We study this sound emission with a very simple spectroscopic technique and observe resonances which are characteristic for natural frequencies of a cylindrical body. From a fit of the experimental frequency positions to calculated values, we determine a sound velocity of c T = 4 m/s for a gel sample with porosity φ = 97.5%. This low sound velocity can only be interpreted as the transverse sound mode predicted by Biot’s theory for sound propagation in …
Integration of HVSR measures and stratigraphic constraints for seismic microzonation studies: the case of Oliveri (ME)
2014
Abstract. Because of its high seismic hazard the urban area of Oliveri has been subject of first level seismic microzonation. The town develops on a large coastal plain made of mixed fluvial/marine sediments, overlapping a complexly deformed substrate. In order to identify points on the area probably suffering relevant site effects and define a preliminary Vs subsurface model for the first level of microzonation, we performed 23 HVSR measurements. A clustering technique of continuous signals has been used to optimize the calculation of the HVSR curves. 42 reliable peaks of the H/V spectra in the frequency range 0.6–10 Hz have been identified. A second clustering technique has been applied t…
Music in the Dark: Soundscapes in Christiane Ritter’s A Woman in The Polar Night
2020
In A Woman in the Polar Night (Eine Frau erlebt die Polarnacht, 1938), Christiane Ritter, a well-to-do Austrian housewife, describes her experience as the first central European woman to overwinter on Svalbard (1934–35). Ritter’s prose is extraordinary in its lyrical simplicity, and in German editions the text is interspersed with her paintings of the scenes that at first were so alien and changing, yet became so familiar and loved.
 Although stationed on the north coast of Svalbard with minimal human contact and without any recourse to the music with which Ritter had been surrounded in Austria, A Woman in the Polar Night is a text that is full of references to sound, natural sounds th…
Can Dasymetric Mapping Significantly Improve Population Data Reallocation in a Dense Urban Area?
2016
The issue of reallocating population figures from a set of geographical units onto another set of units has received a great deal of attention in the literature. Every other day, a new algorithm is proposed, claiming that it outperforms competitor procedures. Unfortunately, when the new (usually more complex) methods are applied to a new data set, the improvements attained are sometimes just marginal. The relationship cost-effectiveness of the solutions is case-dependent. The majority of studies have focused on large areas with heterogeneous population density distributions. The general conclusion is that as a rule more sophisticated methods are worth the effort. It could be argued, however…
February 2017 extreme Saharan dust outbreak in the Iberian Peninsula: from lidar-derived optical properties to evaluation of forecast models
2018
Abstract. An unprecedented extreme Saharan dust event was registered in winter time from 20 to 23 February 2017 over the Iberian Peninsula (IP). We report on aerosol optical properties observed under this extreme dust outbreak through remote sensing (active and passive) techniques. For that, EARLINET (European Aerosol Research LIdar NETwork) lidar and AERONET (AErosol RObotic NETwork) Sun-photometer Cimel CE 318 measurements are used. The sites considered are: Barcelona (41.38º N, 2.17º E), Burjassot (39.51º N, 0.42º W), Cabo da Roca (38.78º N, 9.50º W), Évora (38.57º N, 7.91º W), Granada (37.16º N, 3.61º W) and Madrid (40.45º N, 3.72º W). In general, large aerosol optical depths (AOD) and …
Temporal loudness weights in background noise: Data and models
2019
Previous studies consistently showed that human listeners primarily consider the beginning of a time-varying sound when judging its overall loudness, and place less weight on subsequent temporal portions. However, all experiments studying this primacy effect in temporal loudness weights presented the target sound in quiet. Here, we compared temporal weights when the target sound was either presented in quiet or in a continuous background noise, and for a variation in the level of the target sound across a range of 60 dB. The target sound was a time-varying narrowband noise, the background noise was a continuous bandpass-filtered noise. In all conditions, we observed the expected primacy eff…
Relationships between diffuse CO 2 emissions and volcanic activity on the island of Vulcano (Aeolian Islands, Italy) during the period 1984-1994
2002
Measurements of CO2 flux from the ground were periodically carried out on the island of Vulcano (Aeolian Islands, Italy) between 1984 and 1994. Three high-flux areas were identified at the foot of the volcanic cone (La Fossa), either inside or very close to the main village. Effect of the choice of the sampling grid was evaluated. A different sampling grid resulted in similar distribution patterns, but with different CO2 fluxes. Therefore, the absolute estimate of the total flux from the investigated area includes a large degree of uncertainty, but repeated measurements with permanent sampling sites are accurate and can detect small changes. No correlation of the flux with atmospheric param…
EnvDB, a database for describing the environmental distribution of prokaryotic taxa.
2009
Summary EnvDB is a database that classifies the environmental samples and their associated 16S rDNA sequences currently stored in GenBank. The samples were cat- egorized in a three-level, hierarchical classification of media: the five upper levels (terrestrial, aquatic, thermal, host-associated and other) are further decomposed in 20 intermediate (such as marine, marine sediments, freshwater, soil, gut, etc.) and 47 lower levels (for instance, soil is further decomposed in forest, agricultural, wetlands, grasslands, tropical, arid, etc.). Each sample was also characterized with nine environmental features: polluted, diseased (for clinical samples), acidic, alkaline, hot environment, cold en…
