Enucleation Followed by Open Packing of Iodoform Gauze in Mandibular Unicystic Ameloblastoma: A Case Report

Vijay Kumar, Raman Kant Sinha

Unicystic ameloblastoma is a clinical subtype of ameloblastoma. According to Ackermann there are three types of unicystic ameloblastoma microscopically. Luminal unicystic ameloblastoma belongs to the Ackermann type-1 unicystic ameloblastoma. They frequently affect young people and may behave aggressively. A general agreement has been made for aggressive type of unicystic ameloblastomas are managed aggressively to eradicate the lesions completely by radic...

Negatively Charged Oxygen Ions as a Plasma Diagnostic Tool: Application to Comets

Sreekala Gopinathan, Sijo Sebastian, Noble Abraham, Savithri Devi, Venugopal Chandu, Renuka Gangadharan
We study the stability of the ion-acoustic (IA) wave in a collisional plasma composed of hydrogen, positively and negatively charged oxygen ions, electrons and neutral atoms. This composition approximates very well the plasma environment around a comet. A solution of the dispersion relation yields a frequency for the IA wave at around the hydrogen plasma frequency. The growth/ damping rate is sensitively dependent on the ring parameters u⊥s (the ring speed) an...

Simulation and Comparative Analysis of SS-LMS & RLS Algorithms for Electronic Dispersion Compensation

Gurpreet Kaur, Gurmeet Kaur

In this paper electronic feed forward equalization is performed to mitigate the link chromatic dispersion. The equalizer coefficients are computed by a decision-directed process based on the sign-sign least mean square and the recursive least square algorithm. Therefore, this paper evaluates the performance of these algorithms in chromatic dispersion compensation at bit rate of 10 Gb/s. This paper compares these two adaptation algorithms for receiver based on analogue elec...

Test Site/In-Situ Data for Earth Observation in Case of Limited Field Data Access

Rustam B. Rustamov, Sabina N. Hasanova

Remote sensing (RS) is the method making possible of observing, recording and collecting of objects or features on the Earth from distant places. There is no direct contact with the investigated objects. It is reflecting radiation scattering from the Earth surface content information in the form of wavelengths in different range of spectrum. Main source of the information comes from satellites forming as space image. A further step of the analyses of spa...

Validation of Optimum Algorithm Parameters Required to Estimate Vocal Tract Shape for Children Using LPC Analysis

Nilashree S. Wankhede, Milind S. Shah

Severe or profound deafness in hearing impaired children, can curb their ability to speak due to the lack of auditory feedback. There has been a considerable attempt in developing commercial speech training aids for such children which give feedback of acoustic and articulatory parameters. Speech training aids based on visual feedback of vocal tract shape (VTS) are reported to be useful for the improvement in speech production. Since realistic VTS estima...

A HILIC Mechanism Discussion for the Retention of HP-β-CD

Jianqiang Wei, Hui Wang, Song Wu
A hydrophilic interaction liquid chromatography (HILIC) method coupled with a refractive index (RI) detector was developed for the determination of hydroxypropyl-β-cyclodextrin (HP-β-CD). This HILIC method used simple acetonitrile/water (80/20, v/v) as the mobile phase to provide sufficient retention for HP-β-CD. The method was found to be specific without interference from the other constituents in pharmaceutics. The method was also validated for linearity and accuracy of t...
