Dental anatomy is the study of morphology of various teeth in human dentitions. The application of dental anatomy in clinical practice is important, and dentist should have a thorough knowledge regarding the morphology of the teeth. At times as a result of genetic variation, environmental factors, diet of an individual and race, variations in the morphology of the teeth can be observed. These v...

-In radial distribution network with no discontinuities in feeders’ impedances the shape of traveling wave induced by an SLG fault inception will be modeled by multiple refractions and reflections from busbar, fault and loads. The initial propagation zone presents a rigorous polarity disposition of residual currents, with sound residuals having the same polarity. We can determine the minimal sa...

Dens invaginatus is a developmental anomaly resulting from infolding of the surface of the tooth crown before calcifi cation has occurred. While several mechanisms have been proposed for the cause of this phenomenon the exact etiology is not known. The malformation shows a broad spectrum of morphologic variations and frequently results in early pulp necrosis. The nature of the problem may incre...

OBJECTIVES To evaluate the frequency of developmental dental anomalies in the Indian population. METHODS This prospective study was conducted over a period of 1 year and comprised both clinical and radiographic examinations in oral medicine and radiology outpatient department. Adult patients were screened for the presence of dental anomalies with appropriate radiographs. A comprehensive clini...

The quality of static phones (e.g. vowels, fricatives, nasals, laterals) generated by articulatory speech synthesizers has reached a high level in the last years. Our goal is to expand this high quality to dynamic speech, i.e. whole syllables, words, and utterances by re-synthesizing natural acoustic speech data. Re-synthesis means that vocal tract action units or articulatory gestures, describ...

Are voiceless approximants categorically distinct from voiceless fricatives? We address this question by means of acoustic analysis of voiceless laterals in Icelandic, Welsh, and the endangered variety Estonian Swedish. All three have a voiceless lateral functioning in contrast to a voiced lateral approximant. The analysis focused on duration – including any period of voicing (‘pre-voicing’) ju...

This paper presents jaw movement data for the coronal consonants of Central Arrernte. It compares jaw movement for stops with jaw movement for nasals and laterals, across dental, alveolar, retroflex and alveo-palatal places of articulation. Results suggest that when there is a clear spectral peak for the release burst, as is the case primarily for the palatal, but also for the alveolar and retr...

The relationship between root stunting caused by the cereal cyst nematode and levels of two root growth inhibiting hormones, abscisic acid and ethylene, was investigated in aseptically cultured root segments and in intact roots of two oat cultivars differing in tolerance to the nematode. Cultured root segments of oat cultivars New Zealand Cape (tolerant) and Sual (intolerant) were inoculated wi...

In the project HERON, we developed a framework for articulatory speech synthesis for European Portuguese. The system combines several modules, developed or adapted in the project. The Linguistic Processing model uses new syllabification and grapheme-to-phone modules developed in the project. The construction of the gestural scores is performed using an adapted version of TADA (TAsk Dynamic Appl...
