On the Function of the Spiral Prominence
1967
The suppression of hematic circulation of the internal auditory artery of a guinea-pig causes the necrosis of all anatomic formations of the cochlear duct, with the exception of the organ of Corti of the vestibular segment. The author confirms his hypothesis about the origin of the cochlear endolymph and thinks that the prominence provides the vegetative life of the organ of Corti.
Vidējās paaudzes prasmes atpazīt komerciāla rakstura ziņojumus sociālajā tīklā Facebook.com
2019
Sociālie tīkli ar katru dienu kļūst arvien populārāki un šobrīd tiek izmantoti kā vieni no galvenajiem informācijas avotiem. Sabiedrība patērē publicēto saturu, gūst zināšanas, rezultātā veidojot savu pasaules redzējumu. Ne visa pieejamā informācija ir kvalitatīva, tāpēc svarīgi iepazīt sociālo tīklu vidi un prast tajā orientēties. Facebook.com sociālais tīkls lielāko daļu peļņas gūst no reklāmu ieņēmumiem, līdz ar to ir svarīgi informēt sabiedrību, ka Facebook.com tiek izmantots ne tikai izklaidei, bet arī komerciāliem nolūkiem. Reklāma ir attīstījusies un pielāgojusies digitālajai videi. Sociālajā tīklā Facebook.com komerciāla rakstura ziņojumu formāti ir tik daudzveidīgi, ka tas sniedz i…
Vitamin A deficiency increases noise susceptibility in guinea pigs.
1990
The effect of vitamin A deficiency in guinea pigs on noise-induced temporary threshold shift (TTS) was evaluated after short (15 min) acoustic overstimulation with a moderate (90 dB) broad-band white noise. Some guinea pigs were fed ad libitum a purified diet deficient in vitamin A (VAD group) until biochemical signs of deficiency occurred. A second, control group (VA group) received the same diet as well as 100 IU vitamin A daily by pharyngeal tube. Cochlear potentials were recorded by special computerized equipment using implanted electrodes. Before acoustic stimulation, a baseline value was determined with a test stimulus [90 dBA (A-filter according to usual DIN instructions)] correspond…
Ascorbic acid reduces noise-induced nitric oxide production in the guinea pig ear.
2008
Objectives: Noise-induced hearing loss can be caused, among other causes, by increased nitric oxide (NO) production in the inner ear leading to nitroactive stress and cell destruction. Some studies in the literature suggest that the degree of hearing loss (HL) could be reduced in an animal model through ascorbic acid supplementation. To identify the effect of ascorbic acid on tissue-dependent NO content in the inner ear of the guinea pig, we determined the local NO production in the organ of Corti and the lateral wall separately 6 hours after noise exposure. Study Design: Prospective animal study in guinea pigs. Methods: Over a period of 7 days, male guinea pigs were supplied with minimum (…
Hierarchizing Energy Saving Strategies in Wine Industry by Advanced Modelling of Chilling Units Operation
2019
Wineries are energy intensive industries and in order to make the production process more sustainable, solutions for an efficient use of energy should be implemented. Large surveys conducted in the wineries sector have highlighted the importance of performing accurate energy audits and have identified in the installation of efficient cooling/refrigeration systems the most promising solutions in a variety of cases. Unfortunately, the savings achieved by such energy efficient solutions is often calculated by highly simplified approaches, which do not take into consideration the actual operating conditions of the equipment (highly variable on a seasonal and daily basis). In this paper a system…
The Audit of SME’s Informatics Systems
2018
Basically, ERP implies a policy that reflects what it means to think and act for the purpose of economic processes and is therefore considered a strategic management solution. The new business model with process-focused operations increases productivity and meets the economic performance standards. The economic operational stages must be integrated in order to trigger workflows, to control the flow of information, and to create connections between the organization, suppliers, and customers. All this requires organizational changes, technological updates, and, eventually, a new identity for the organization itself. The present paper proposes a specific approach to the procedures needed to pe…
Interactions in the network of Usher syndrome type 1 proteins
2004
International audience; Defects in myosin VIIa, harmonin (a PDZ domain protein), cadherin 23, protocadherin 15 and sans (a putative scaffolding protein), underlie five forms of Usher syndrome type I (USH1). Mouse mutants for all these proteins exhibit disorganization of their hair bundle, which is the mechanotransduction receptive structure of the inner ear sensory cells, the cochlear and vestibular hair cells. We have previously demonstrated that harmonin interacts with cadherin 23 and myosin VIIa. Here we address the extent of interactions between the five known USH1 proteins. We establish the previously suggested sans-harmonin interaction and find that sans also binds to myosin VIIa. We …

Texture et paradoxes auditifs dans la musique récente de Michaël Levinas
2020
Parmi les courants musicaux apparus après 1945, le spectralisme a été celui dont les fondements théoriques, les techniques d’écriture et les sources d’inspiration ont été le plus fécondés par les recherches en acoustique, en psychoacoustique et en perception de la musique. Les questionnements musicaux de Michaël Levinas, comme ceux de Grisey, Murail, Dufourt, Saariaho, Hurel, Dalbavie, Maresz et d’autres, se sont nourris de notions telles que spectre, transitoires, résonance, battements, sons de combinaison, inharmonicité, rugosité, seuil perceptif,masquage, effet Doppler, etc. Cependant, s’il partage avec ses collègues ce socle de connaissances, elles ne l’ont pas conduit aux mêmes solutio…
