Many documents describe standardized methods and standard equipment requirements in the field of audiology and hearing aids. These standards will ensure a uniform level and a high quality of both the methods and equipment used in audiological work. The standards create the basis for measuring performance in a reproducible manner and independent from how and when and by whom parameters have been measured. This article explains, and focuses on, relevant acoustic and electromagnetic compatibility parameters and describes several test systems available.

Astaxanthin (AST), as a natural antioxidant, has broad application prospects in medicine and health products. However, its highly unsaturated structure and significant lipophilic characteristics limit its dispersibility and bioavailability, thereby restricting its application in food, medicines, and nutraceuticals. To overcome these limitations, researchers have proposed the use of nano delivery systems.

Sepsis-associated encephalopathy (SAE) is a severe and frequent septic complication, characterized by neuronal damage as key pathological features. The astrocyte-microglia crosstalk in the central nervous system (CNS) plays important roles in various neurological diseases. However, how astrocytes interact with microglia to regulate neuronal injury in SAE is poorly defined.

Triboelectric nanogenerators (TENGs) have attracted great attention due to the simple manufacturing process, low cost, and diverse forms of energy harvesting. However, the energy collected by individual TENG is relatively limited, making it necessary to develop new method to enhance the energy harvesting capability of TENG. Here, we design a hybridized TENG that integrates a droplet-driven TENG and a wind-driven TENG, which exhibits excellent electrical performance.

This paper investigates the impact of workload on leadership roles within the Austrian IT sector, by also paying attention to differences between genders. The research adopted a prospective design, selecting IT professionals, stratified by those with and without personnel responsibility and examined further through the lens of gender. A total of 200 participants completed the survey, where the modified German version of the Copenhagen Psychosocial Questionnaire (COPSOQ) served as the primary tool, which evaluated dimensions such as demands, influence, interpersonal relations, work interface, and conflicts.
