Acoustic Correction of the Regional Theatre of Bejaia (Algeria)
No full textTheatres must have an adequate reverberation time depending on their intended use. In this paper the acoustic characteristics of the regional theatre of Bejaia (Algeria) built in 1936 is discussed. The hall has a regular geometry with the shape of a shoebox, with a capacity of 420 seats. Measurements of the acoustic characteristics were carried out using the bursting of an air-inflated balloon. The room has an excessive reverberation time, which is not suitable for the performance of prose shows, and so it is necessary to carry out an adequate acoustic correction to reduce the reverberation time and increase the STI to improve speech understanding. The aim of this work is to analyze, using architectural acoustics software, the conditions for improving the acoustics of the room in order to reduce the reverberation time. The study uses numerical modeling to evaluate the effects of modifying the material of the stage tower or inserting surfaces with adequate acoustic absorption. © 2025, Free University of Bozen Bolzano.

Fermented seeds (“Zgougou”) from aleppo pine as a novel source of potentially probiotic lactic acid bacteria
No full textMicroorganisms inhabiting fermented foods represent the main link between the consumption of this food and human health. Although some fermented food is a reservoir of potentially probiotic microorganisms, several foods are still unexplored. This study aimed at characterizing the probiotic potential of lactic acid bacteria isolated from zgougou, a fermented matrix consisting of a watery mixture of Aleppo pine′s seeds. In vitro methods were used to characterize the safety, survival ability in typical conditions of the gastrointestinal tract, and adherence capacity to surfaces, antimicrobial, and antioxidant activities. Strains belonged to the Lactobacillus plantarum group and Enterococcus faecalis showed no DNase, hemolytic, and gelatinase activities. In addition, their susceptibility to most of the tested antibiotics, satisfied some of the safety prerequisites for their potential use as probiotics. All the strains tolerated low pH, gastrointestinal enzymes, and bile salts. They displayed a good antibacterial activity and antibiofilm formation against 10 reference bacterial pathogens, especially when used as a cell-free supernatant. Furthermore, the lactic acid bacteria (LAB) strains inhibited the growth of Aspergillus flavus and Aspergillus carbonarius. Finally, they had good antioxidant activity, although depending on the strain. Overall, the results of this work highlight that zgougou represents an important reservoir of potentially probiotic LAB. Obviously, future studies should be addressed to confirm the health benefits of the LAB strains
Acoustic properties of two emblematic theaters in Algeria: The case of the National Theater of Algiers TNA and the Regional Theater of Bejaia TRB
No full textIn this paper, the acoustics of multi-purpose colonial theaters in Algeria, those of Algiers and Bejaia, are studied to evaluate their acoustic conditions (suitability for music and speech) in view of their architecture's evolution. To do, acoustics measurements were performed inside them according to the ISO 3382-1 Standard in unoccupied conditions. The average values of acoustic parameters (EDT, T30, C80, and D50) are reported in frequency domain from 125 to 4 kHz. Furthermore, maps of spatial distribution of T30, C80 at the frequency of 1 kHz, and STI are reported. Results show that the Algiers theater is the more appropriate venue for multipurpose performances (with a fairly low RT of 1.5 s in average mid-frequencies), whereas the Bejaia theater is only suitable for musical performances (with a high RT of 2.5 s in average mid-frequencies)
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Acoustics and prayers: investigations on the Great Mosque of Tirana, Albania
No full textThe Great Mosque of Tirana, also called Namazgâh Mosque, is the largest mosque in the Balkans. After the end of the communism, the mosque was requested by the numerous Muslim citizens, as there was a lack of a religious building to pray in. The mosque is characterized by 50 m high minarets, crowned on the perimeter by a 35 m high central dome surmounted by six niches with half domes. The Great Mosque has an area of 600 m2, whose floor is covered with a precious carpet, and the interior is illuminated by large windows on the side walls. This paper deals with the acoustic characterization of the main prayer room of the Great Mosque and the comparison with the values measured in other mosques. A short digression about the historical background, as well as the measurement techniques according to ISO 3382 have been given

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
