The novel heterometallic aggregates [Ag(8)Cu(2)(C(2)C(6)H(4)X)(6)(PPh(2)C(6)H(4)PPh(2))(6)][PF(6)](4) (X = H, 1; OMe, 2; NMe(2), 3) were prepared by the self-assembly reactions starting from simple precursors. These compounds consist of the central [Ag(6)Cu(2)(C(2)C(6)H(4)X)(6)](2+) clusters capped by two tripodal fragments [Ag(diphosphine)(3)](+). The solid state structures of complexes 1 and ...
<p class="BodyA"><strong>Background: </strong>COVID-19 pandemic is caused by SARS CoV2. The last reference of was Spanish flu in 1918 which hearing loss many patients. effect COVID-19 an interesting issue audiology. Not much studies have been done; therefore, this kindled our interest to a study on audiological profile asymptomatic patients.<strong></strong></p&...
Luminescent solar concentrators (LSCs) generally consist of transparent polymer sheets doped with luminescent species. Incident sunlight is absorbed by the luminescent species and emitted with high quantum efficiency, such that emitted light is trapped in the sheet and travels to the edges where it can be collected by solar cells. LSCs offer potentially lower cost per Wp. This paper reviews res...
Introduction: Although the incidence and prevalence of chronic suppurative otitis media (CSOM) has been decreased in recent decades, but it is still a major health problem in both developing and developed countries. CSOM can cause major and life-threatening complications such as hearing loss, meningitis and cerebral abscess. Since hearing loss is the most common complication of CSOM, we aimed ...
OBJECTIVE To describe the audiometric results after stapes surgery in a consecutive series of patients with stapes footplate ankylosis combined with another ossicular middle ear anomaly. STUDY DESIGN A retrospective analysis of charts collected between 1986 and 2001. SETTING A tertiary referral center. PATIENTS A total of 25 patients (30 ears) underwent exploratory tympanotomies and ossic...
We evaluated the validity of remote pure tone audiometric testing conducted from North America on subjects in South Africa. Desktop-sharing computer software was used to control an audiometer in Pretoria from Dallas, and PC-based videoconferencing was employed for clinician and subject communication. Thirty adult subjects were assessed, and the pure tone audiometric thresholds (125-8000 Hz) obt...
