Exhaled respiratory particles during singing and talking

Choir singing has been suspended in many countries during the Covid-19 pandemic due to incidental reports of disease transmission (Hamner et al. Citation2020). The mode of transmission has been attributed to exhaled droplets, but with the exception of a study on tuberculosis from 1968, there is presently almost no scientific evidence of increased particle emissions from singing (Loudon and RobertsChoir singing has been suspended in many countriesduring the Covid-19 pandemic due to incidental reportsof disease transmission.

Five-satellite-sensor study of the rapid decline of wildfire smoke in the stratosphere

Smoke from western North American wildfires reached the stratosphere in large amounts in August 2017. Limb-oriented satellite-based sensors are commonly used for studies of wildfire aerosol injected into the stratosphere (OMPS-LP (Ozone Mapping and Profiler Suite Limb Profiler) and SAGE III/ISS (Stratospheric Aerosol and Gas Experiment III on the International Space Station)). We find that these m

Studies of X-Ray Optics And Polarimetry For Synchrotron Radiation

Popular Abstract in English Among the large variety of experiments performed in science, a common one is to pass a light beam through a sample, the object to be studied, and to study the outcomes of the light-sample interaction. Many light sources have been used for this purpose, like light bulbs and lasers. A modern light source used nowadays is the so-called storage ring. In the storage rings elSynchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies have made possible to obtain very low emittance electron beams, which together with the use of undulators allow to guide a very high photon flux into a very small beam size required by the experiments. Development of sources has been accompanied with eq

Operationalization of Risk Appetite - Balance Sheet Projections of Banks

The financial crisis in 2008 enlightened several shortcomings in the performance of the banking sector. As a result of this a more rigid regulatory framework, Basel III, has been developed which raises the requirements of banks’ capital and liquidity structure and internal capital adequacy processes. This involves evaluating potential future risks related to the strategy and risk appetite of a ban

Wave-modes of a double-plate system with joists and cavity

Lightweight walls and floors are often designed as frameworks of studs with plates on each side - a double-plate structure. The free wave-modes and periodic wave motion of a double-plate system reinforced by joists are analysed in the present paper (as the insertion loss and impact sound insulation have been studied in previous papers). The free wave-modes can in a future step be used in connectio

Mamma kan ha hetat mamma även på stenåldern

Mamma kan ha hetat mamma även på stenåldern Mamma kan ha hetat mamma även på stenåldern Av Gisela Lindberg - Publicerad den 29 mars 2021 "Mamma" och "näsa" är exempel på basala ord med liknande språkljud i de flesta av jordens språk. Foto: Unsplash. I de flesta av världens språk har ett antal basala ord liknande ljud. Till exempel innehåller orden för mamma och näsa ofta ”m” och ”n” i varje språk.

Doubling the spectrum of time-domain induced polarization: removal of non-linear self-potential drift, harmonic noise and spikes, tapered gating, and uncertainty estimation

This paper presents an advanced signal processing schemefor time-domain induced polarization full waveform data.The scheme includes several steps with an improvedinduced polarization (IP) response gating design usingconvolution with tapered windows to suppress highfrequency noise, a logarithmic gate width distribution foroptimizing IP data quality and an estimate of gatinguncertainty.

Non-modal voice quality in Chichimeco - "Hablamos más con la garganta"

In this thesis, the phonetics and the phonology of non-modal voice quality and other glottal features in Chichimeco (Oto-Manguean, Mexico) are described. For this investigation, I analysed recordings I made in Mexico in spring 2017 as well as recordings enclosed in Lastra (2009b, 2016). Descriptions of this language have been published since the 1930s but non-modal phonation has not received the

Strategic Implementation of CSR - A Driver for Organizational Resilience?

CSR has been gaining significance in the field of strategic management, as growing societal expectations have resulted in additional pressures for firms to act responsibly. Particularly the heightened sense of urgency regarding environmental sustainability has further amplified this development. Simultaneously, the global business landscape is changing at an accelerated pace and in an unprecedente

Reduction of the structure-acoustic problem using normal modes and lanczos vectors

The coupled structure-acoustic problem is studied using the finite element method. An efficient strategy for solving the coupled eigenvalue problem is proposed. The strategy uses a limited number of the uncoupled structural normal modes and acoustic fluid normal modes together with a set of interface-dependant Lanczos vectors for each domain to reduce the coupled problem. The Lanczos vectors are c
