Emergent Spin‐Glass Behavior in an Iron(II)‐Based Metal–Organic Framework Glass
Advanced Functional Materials, EarlyView.A one‐pot, solvent‐free synthesis yields an Fe2+‐based metal‐organic framework (MOF) glass featuring a continuous random network structure. The material exhibits spin‐glass freezing at 14 K, driven by topological‐disorder and short‐range magnetic frustration, showcasing the potential of MOF glasses as a plattform for cooperative magnetic phenomena in ...

Advanced Functional Materials, EarlyView.Photomultiplication organic photodetectors (PM OPDs) are an attractive strategy for health‐monitoring. Here, PM‐OPDs are reported with a specific detectivity of 5.7 × 1012 Jones and external quantum efficiency values of 3500% under −10 V. The dynamics of carrier trapping in these devices are elucidated through trap selective spectroscopical techniques.

Noise Levels: A database of industrial noise level measurements
Online Review, 1988The Noise Levels database has been developed at the Canadian Centre for Occupational Health and Safety for the computerized information system, CCINFO. The database documents measured noise levels from a broad spectrum of industrial settings. Industrial hygienists, noise control engineers, researchers, health and safety committee members, and ...

Fish Hatchery Noise Levels and Noise Reduction Techniques
Journal of Agricultural Safety and Health, 2015This study examined occupational noise within two rearing facilities at a production fish hatchery and evaluated two simple noise reduction techniques. Ambient noise levels in the hatchery tank room ranged from 50 dB in the absence of flowing water to over 73 dB when water was flowing to all 35 tanks under typical hatchery operating procedures ...

Pipeline blowdown noise levels and noise modelling
Applied Acoustics, 2020Abstract High pressure gas venting operations, known as blowdowns, such as from steam driven power plants, and gas pipelines, are known to produce significant noise. Such noise can be of concern for those working or living near such operations. Therefore, the ability to accurately predict blowdown noise, and prescribe appropriate safety equipment ...

Noise levels in dental practice
The Journal of the Acoustical Society of America, 1999Noise can cause unwanted masking of sounds, interference with speech, even pain and injury, and temporary or permanent loss of hearing. Concerning exposure of noise levels at the workplace, industrial plants and huge machines are usually considered. However, there are ‘‘clean’’ jobs where people are exposed to significant noise. One example, which will

Farm Equipment Noise Exposure Levels
American Industrial Hygiene Association Journal, 1968Abstract Noise levels recorded during performance tests conducted at the College of Agriculture, University of Nebraska, on 58 new tractors and 20 other types of farm machinery were of such intensity, duration, and distribution as to indicate a potential permanent noise-induced hearing loss to the agricultural worker.

AM noise impact on low level phase noise measurements
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2002The influence of the source AM noise in microwave residual phase noise experiments is investigated. The noise floor degradation problem, caused by the parasitic detection of this type of noise by an unperfectly balanced mixer, is solved thanks to a refinement of the quadrature condition.
