Dental drill noise reduction using a combination of active noise control, passive noise control and adaptive filtering [PDF]
, 2007 Dental drills produce a characteristic high frequency, narrow band noise that is uncomfortable for patients and is also known to be harmful to dentists under prolonged exposure. It is therefore desirable to protect the patient and dentist whilst allowing

Advanced Functional Materials, EarlyView.The plasma edge of transparent conducting oxide SrNbO3 shifts from ∼2 eV in the visible range to 1.37 eV in the near‐infrared region by off‐stoichiometry using the vacancy sites as quasi‐substitutional virtual elements. This work advances the stoichiometry engineering of perovskite oxides using oxide molecular beam epitaxy, allowing synthesis beyond ...

Evaluation of integral exposure energy load on aural analyzer of miners [PDF]
The individual exposure integral noise load on workers before the beginning of hearing impairment was determined for a group of 20 male miners who had worked with drilling equipment and harvesters for 8 to 20 years before the onset of the disability ...

Human response to vibration in residential environments (NANR209), executive summary [PDF]
, 2012 The aim of the Defra-funded project NANR209 ‘Human response to vibration in residential environments’ was to develop exposure-response relationships for vibration experienced in residential environments from sources outside of the residents’ control. The

Advanced Functional Materials, EarlyView.This review synthesizes the evolution of radiative heat transfer, emphasizing the transition from far‐field to near‐field regimes. Traditional frameworks, such as Planck's law, are revisited alongside modern innovations like fluctuational electrodynamics. Applications span nanoscale thermal management, energy harvesting, and thermophotovoltaic systems.

Advanced Functional Materials, EarlyView.The relationship between primary polymer structure and pattern quality in the directed self‐assembly of chemically modified polystyrene‐block‐poly(methyl methacrylate) derivatives is explored. The perpendicular lamellae are aligned, with a periodicity below 20 nm. No parallel orientations or dislocations form, and line patterns are well defined over an

Noise Induce Stress Assessment via Salivary Cortisol Measuring
بهداشت و ایمنی کار, 2013 Introduction: Noise exposure is known as a risk factor for hearing loss and one of its effects is noise-induced stress. Cortisol, as stress hormone- is used in noise-induced stress assessments studies.
