Getting Therapeutic Sound Waves Through Thick Skulls（图）
Therapeutic Sound Waves Thick Skulls
2017/9/1
Ultrasound brain surgery has enormous potential for the treatment of neurological diseases and cancers, but getting sound waves through the skull and into the brain is no easy task. To address this pr...
Low vitamin D status in Europe: moving from evidence to sound public health policies
Low vitamin D status public health policies
2018/11/28
There is no doubt that interest in vitamin D has burgeoned over the past few decades. Between 1995 and 2015, annual peer-reviewed, vitamin D–related publications have quadrupled (1). Over this same pe...
Sound separates cancer cells from blood samples
Sound separates cancer cells blood samples
2015/4/13
Separating circulating cancer cells from blood cells for diagnostic, prognostic and treatment purposes may become much easier using an acoustic separation method and an inexpensive, disposable chip, a...
New 'T-ray' tech converts light to sound for weapons detection, medical imaging
New 'T-ray' tech light to sound weapons detection medical imaging
2014/6/12
A device that essentially listens for light waves could help open up the last frontier of the electromagnetic spectrum—the terahertz range.
Manufacturing sound absorber based on combined recycling of polyethylene trephetalat and polystyrene at low and median frequencies
plastic recycling polyetylen trephetalat (PET) polyetylen (PE) combined recycling low frequency sound absorber
2009/12/15
Background and aim: Noise pollution is one of the main cause of occupational hearing loss. According to WHO reports in many countries workers have been exposed to 85 - 90 dB noise level. The purpose o...
Relation between speaking space of the /s/ sound and freeway space in dentate and edentate subjects
Phonetics Dental occlusion Denture complete Jaw relation record
2009/10/20
The purpose of this study is to assess the relation between the speaking space of the /s/ sound and the freeway space in two subject groups. One group had natural dentition (Group I, n = 61) and the o...
Contraction Gap versus Shear Bond Strength of Dentin Adhesive in Sound and Sclerotic Dentins
Contraction gap Shear bond strength Sclerotic dentin
2009/9/14
To evaluate the effect of a dentin adhesive on sclerotic dentin, contraction gap width and shear bond strength were measured. Dentin cavity wall was pretreated with an experimental dentin bonding syst...
Hardness and Elasticity of Sound and Caries-affected Primary Dentin Bonded with One-step Self-etch Adhesive
Hardness Young's modulus Nanoleakage Caries-affected dentin Sound dentin
2009/9/14
Biomechanical properties of bonded dentin are important for resin restorations. We hypothesized that there are no differences in the hardness and elasticity of sound and caries-affected primary dentin...
The accuracy of human sound localization in 360 degrees of azimuth was determined underwater in a free field. The location indicator was a pointer in the median plane. Accuracy of the response was def...
Calculation of the relative speed of sound in a gas mixture
frequency spectrum speed sound gas mixture
2009/7/20
Since the frequency spectrum of a voice signal is directly dependent on the velocity of sound, studies of speech spectra include the problem of calculating the speed of sound in the gas mixture being ...
Noise-induced neurologic disturbances in divers exposed to intense water-borne sound:two case reports
noise hearing divers
2009/6/8
Divers may be exposed to intense noise underwater. Two cases of neurologic disturbances during experimental exposures to 15 min of continuous underwater sound are described. Sound exposure in the firs...
Effects of Stimulation Side on the Auditory Evoked Magnetic Fields: Objective Assessments of Sound Localization in Bone-conducted Ultrasonic Perception
ultrasound bone-conduction MEG N1m laterality auditory cortex
2009/6/5
Bone-conducted ultrasound (BCU) is perceived even by those who are profoundly sensorineural deaf. A novel hearing-aid using BCU perception, which transmits amplitude-modulated ultrasound by bone-condu...
Effects of Rise-time of Sound Stimulus on Auditory Evoked Magnetic Fields
Auditory cortex N1m rise-time sound energy rising-speed
2009/6/5
Although several studies have reported that the rise-time of sound stimulus affects on auditory evoked magnetic fields, effects of each parameter which vary in connection with rise-time—whole energy, ...
Recreational scuba divers' aversion to low-frequency underwater sound
low frequency underwater sound diver
2009/6/5
Increasing use of active low-frequency sonar by submarines and ships raises the risk of accidental exposure of recreational divers to low-frequency underwater sound (LFS). This study aimed to characte...
