THE PREVALENCE OF DENTAL DISEASES AMONG WOMEN OF FERTILITY AGE
Numerous studies have been conducted to assess the dental health of women across different age groups, determine the prevalence of dental diseases, and establish preventive measures for complications through a novel treatment approach.
However, it is crucial to conduct a comparative analysis of women in the reproductive age group based on their place of residence. This will allow for an assessment of the dental services provided to them and a determination of the demand for specialized care in rural areas. Such research contributes to the advancement of ecological dentistry alongside clinical and preventive dentistr
Excitation functions of related temperatures of {\eta} and {\eta}0 emission sources from squared momentum transfer spectra in high-energy collisions
The squared momentum transfer spectra of and , produced in
high-energy photon-proton ()
process in electron-proton () collisions performed at CEBAF, NINA, CEA,
SLAC, DESY, and WLS are analyzed. The Monte Carlo calculations are used in the
analysis of the squared momentum transfer spectra, where the transfer undergoes
from the incident to emitted meson or equivalently from the target
proton to emitted proton. In the calculations, the Erlang distribution and
Tsallis-Levy function are used to describe the transverse momentum spectra of
emitted particles. Our results show that the average transverse momentum
(), the initial-state temperature (), and the
final-state temperature () roughly decrease from lower center-of-mass
energy () to higher one, and at several special , this tendency is
broken
Initial and final-state temperatures of emission source from differential cross-section in squared momentum transfer in high energy collisions
The differential cross-section in squared momentum transfer of ,
, , , , , ,
, , and produced in high energy virtual
photon-proton (), photon-proton (), and proton-proton
() collisions measured by the H1, ZEUS, and WA102 Collaborations are
analyzed by the Monte Carlo calculations. In the calculations, the Erlang
distribution, Tsallis distribution, and Hagedorn function are separately used
to describe the transverse momentum spectra of the emitted particles. Our
results show that the initial and final-state temperatures increase from lower
squared photon virtuality to higher one, and decrease with increasing of
center-of-mass energy.Comment: 18 pages, 6 figures. Advances in High Energy Physics, Accepte
Rapidity and Energy Dependences of Temperatures and Volume Extracted from Identified Charged Hadron Spectra in Proton-Proton Collisions at a Super Proton Synchrotron (SPS)
The standard (Bose-Einstein/Fermi-Dirac or Maxwell-Boltzmann) distribution
from the relativistic ideal gas model is used to study the transverse momentum
() spectra of identified charged hadrons (, , ,
, , and ) with different rapidities produced in inelastic
proton-proton () collisions at the Super Proton Synchrotron (SPS). The
experimental data measured by the NA61/SHINE Collaboration at the
center-of-mass (c.m.) energies , 7.7, 8.8, 12.3, and 17.3 GeV are
fitted well by the distribution. It is shown that the effective temperature
( or ), kinetic freeze-out temperature (), and initial
temperature () decrease with the increase in rapidity and increase with
the increase in c.m. energy. The kinetic freeze-out volume () extracted from
the , , , , and spectra decreases with the
rapidity and increase with the c.m. energy. The opposite tendency of ,
extracted from the spectra, is observed to be increasing with the rapidity
and decreasing with the c.m. energy due to the effect of leading protons.Comment: 27 pages, 14 figures. Entropy, accepte
