We report a case of interrupted inferior vena cava (IVC) as a rare developmental defect. Inferior vena cava interruption is usually accompanied with azygos and hemiazygos continuation, and is asymptomatic. Consequently, venous blood from the caudal part of the body reaches the heart via the azygous vein and superior vena cava. A 50 year old female who came for routine health check-up was found ...

The stability behavior of low immersion helical end milling processes is investigated in this paper. Low radial immersion milling operations involve interrupted cutting which induces chatter vibration under certain cutting conditions. Time Finite Element Analysis (TFEA) is suggested for an approximate solution for delayed differential equations encountered during interrupted milling. An improve...

Second language learners perform worse than native speakers under adverse listening conditions, such as speech in noise (SPIN). No data are available on heritage language speakers' (early naturalistic interrupted learners') ability to perceive SPIN. The current study fills this gap and investigates the perception of Russian speech in multi-talker babble noise by the matched groups of high- and ...

Vocal production can be highly deterministic, such that once the central nervous system generates a signal to call, the vocalization is emitted immune to external events. Conversely, vocal production can be modulated by auditory feedback such that interference or disruption can cause an individual to stop calling or, if it continues to call, for the acoustic morphology of the signal to change. ...

background noise exposure is known as a risk factor for hearing loss and one of its effects is noise-induced stress. cortisol as a stress hormone is used in noise-induced stress assessments. objectives the aim of this study was to measure and compare saliva cortisol concentrations in the morning and evening in normal work day and rest day in both case and control groups and to assess the associ...

With the development of mechanized civilization, transportation of goods and people has become fast and convenient, at the expense of transportation noise which has become a serious problem. This paper aims at comparing the acoustical environment of a modern multi-million city (Tokyo) with the situation one to three centuries ago in the corresponding old city (Edo); also at that time one of the...

This study investigated the effects of two parameters (i.e., interruption rate, and duty cycle of interruption) on the perception of periodically interrupted Mandarin speech. Normal-hearing listeners were instructed to identify consonant/vowel/tone/word from isolated Mandarin words and recognize Mandarin sentences when they were temporally interrupted by square wave. Results showed that consist...

conclusions due to the long exposure to the loud noise during the day, hearing loss in drivers is significant. the left ear displays greater loss than the right ear. therefore, strategies to prevent hearing loss in drivers could include education, lifestyle changes and compliance issues related to hearing health, use of personal protective equipment, conducting periodic examinations and early t...

Segmenting the mandibular canal from cone beam CT data, is difficult due to low edge contrast and high image noise. We introduce 3D coherence filtering as a method to close the interrupted edges and denoise the structure of the mandibular canal. Coherence Filtering is an anisotropic non-linear tensor based diffusion algorithm for edge enhancing image filtering. We test different numerical schem...

Strong coupling of electronic and vibrational degrees of freedom entails a low-bias suppression of the current through single-molecule devices, termed the Franck-Condon blockade. In the limit of slow vibrational relaxation, transport in the Franck-Condon-blockade regime proceeds via avalanches of large numbers of electrons, which are interrupted by long waiting times without electron transfer. ...
