Constructing digital assets through blockchain technologies? Unpacking the techno-economic configuration of non-fungible tokens.

Non-fungible tokens (NFTs) are novel techno-economic configurations underpinned by cryptocurrency ledgers that transform digital files like graphic art, music, videos, etc. into digital assets. NFTs are often framed as a way for artists and other creators to profit from their activities, transforming 'experiences' into something for sale.

Emerging Low Detection Limit of Optically Activated Gas Sensors Based on 2D and Hybrid Nanostructures.

Gas sensing is essential for detecting and measuring gas concentrations across various environments, with applications in environmental monitoring, industrial safety, and healthcare. The integration of two-dimensional (2D) materials, organic materials, and metal oxides has significantly advanced gas sensor technology, enhancing its sensitivity, selectivity, and response times at room temperature. This review examines the progress in optically activated gas sensors, with emphasis on 2D materials, metal oxides, and organic materials, due to limited studies on their use in optically activated gas sensors, in contrast to other traditional gas-sensing technologies.

[Factors affecting adherence to CPAP therapy in patients with obstructive sleep apnea syndrome].

Objective: Analysis of factors affecting adherence to continuous positive airway pressure (CPAP) therapy in patients with obstructive sleep apnea (OSA).

Material And Methods: The literature search was carried out using the databases PubMED, Google Scholar, E-library, Cyberleninka for the period 2013-2023 and included reviews and original articles.

Results: The main groups of factors affecting adherence to CPAP therapy in patients with OSA have been established.

[The normal sonographic picture of the paratonsillar region and the prerequisites for ultrasound diagnosis of purulent pathology of the pharynx].

Paratonsillar abscess (PTA) stands out among all otorhinolaryngological diseases, since it can cause life-threatening complications that develop in the shortest possible time due to the close connection of the cellular spaces of the head, neck and mediastinum. In addition to physical examination, computed tomography and magnetic resonance imaging are routinely used to diagnose PTA, sonography is less often used. With the help of the latter, it is possible to reliably distinguish PTA from both paratonsillitis and a number of other diseases, including an aneurysm of the internal carotid artery, using the Doppler mode.
