Status of (3686), (4040), (4160), Y (4260), (4415) and X (4630) charmonia like states
We examine the status of charmonia like states by looking into the behaviour
of the energy level differences and regularity in the behaviour of the leptonic
decay widths of the excited charmonia states. The spectroscopic states are
studied using a phenomenological Martin-like confinement potential and their
radial wave functions are employed to compute the di-leptonic decay widths.
Their deviations from the expected behaviour provide a clue to consider them as
admixtures of the nearby S and D states. The present analysis strongly favour

(4.1 GeV) hybrid, \\backslash\backslash\backslash^\circ^\circc \bar{c}c \bar{c}\backslash$psi \$ (4415) is still not clear as it does not fit to be pure or
admixture state
Subcritical and supercritical fluid extraction a critical review of its analytical usefulness
Subcritical R134a is suggested as a low-pressure alternative to supercritical CO2 in the supercritical fluid extraction technology in particular of palm oil application. Therefore, a measurement of solubility of palm oil in subcritical Rl34a will be carried out at temperatures of 40, 60, 70 and 80°C and pressures up to 300 bar. The solubility of carotene are also will be measured using UV Spectrophotometer. Results obtained from this study will be compared with the previous work and for the first time, simulation for the SFE process of palm oil will be performed using Artificial Neural Network (ANN) and it will be implemented in comparisons as well when the operating conditions of the previous findings are different from this study. It is expected that the solubility of the palm oil in subcritical Rl34a is much higher than SC-C02, and it is expected that R134a could be a viable alternative solvent to supercritical carbon dioxide as R134a could be perform well at a lower pressure used whereas can achieved a higher solubility compared to SC-C0
Talon cusp affecting primary dentition in two siblings: a case report
The term talon cusp refers to a rare developmental dental anomaly characterized by a cusp-like structure projecting from the cingulum area or cement-enamel junction. This condition can occur in the maxillary and mandibular arches of the primary and permanent dentitions. The purpose of this paper is to report on the presence of talon cusps in the primary dentition of two southern Chinese siblings. The 4 years and 2 months old girl had a talon cusp on her maxillary right primary central incisor, while her 2 years and 9 months old brother had bilateral talon cusps on the maxillary primary central incisors. The presence of this rare dental anomaly in two siblings has scarcely been reported in the literature and this may provide further evidence of a hereditary etiology.Article Link:

Clinical Manifestation and Management of Extra-Esophageal Gastroesophageal Reflux Disease
GERD is a condition that gastric content go back into the esophagus. This condition could came disturbances in the respiratory tract, heart and otolaryng. Those extra-esophageal clinical manifestation are common but often miss our attention. So it is important to explorate it further. The management of extra-esophageal GERD is similar with management of GERD. It is included life style modification and reducing refluxate with controlling pH with aggressiveness
Status of quarkonia - like negative and positive parity states in a relativistic confinement scheme
Properties of quarkonia - like states in the charm and bottom sector have
been studied in the frame work of relativistic Dirac formalism with a linear
confinement potential. We have computed the mass spectroscopy and decay
properties (vector decay constant and leptonic decay width) of several
quarkonia - like states. Present study is also intended to identify some of the
unexplained states as mixed P-wave and mixed S-D wave states of Charmonia and
Bottomonia. The results indicate that the X(4140) state can be an admixture of
two P states of charmonium. And the charmonium like states X(4630) and X(4660)
are the admixed state of S - D waves. Similarly, the state recently
reported by Belle II can be a mixed P - states of bottomonium. In the
relativistic framework we have computed vector decay constant and the leptonic
decay width for S wave charmonium and bottomonium. The leptonic decay width for
the mixed states are also predicted. Further, both the masses
and the leptonic decay width are considered for the identification of the
quarkonia-like states.Comment: 14 pages, 2 figure
