Snap, crackle and pop: when sneezing leads to crackling in the neck

Transformations of a crackling jet noise waveform and potential implications for quantifying the “crackle” percept

Testing two crackle criteria using modified jet noise waveforms.

The jet sound quality "crackle" has historically been studied and quantified using the statistics of the pressure waveform. Some investigators have suggested crackle, and its associated shock content, may be better quantified using the statistics of the time derivative of the waveform. Modified waveforms are used to evaluate crackle prediction criteria based on the skewness of each variable. Th...

Wired for Sound: The Essential Connection Between Music and Development

Magazines and network news shows are abuzz reporting the newly discovered links between intellect and music. Dateline NBC entitled their coverage of the new music research "Perfect Pitch." "ZZZt!" "Crackle!" and "Zap!" said Newsweek, in efforts to describe the neural bridges being formed in an infant's brain when stimulated by a parent's voice. "Rat-a-tat-tat" declares Time magazine, describing...

Thyroid dose and dose reduction method from CT scan of head and neck

Introduction: Computed tomography (CT) consists of 11% of all imaging methods, but accounts for approximately 67% of radiation exposure due to diagnostic cases. More than one-third of all CT scans are done in the head and neck area. The thyroid gland is irradiated during CT head and neck. According to studies, this gland has the highest levels of radiation-induced cancer, and i...

Experimental and Numerical Pore Scale Study of Residual Gas Saturation in Water/Gas Imbibition Phenomena

Residual gas saturation is one of the most important parameter in determining recovery factor of water-drive gas reservoir. Visual observation of processes occurring at the pore level in micromodels can give an insight to fluid displacements at the larger scale and also help the interpretation of production performance at reservoir scale. In this study experimental tests in a glass micromod...
