Abstract:
The study conducted by Rompicharla mandal, Guntur district. Dental fluorosis is a developmental disturbance
of dental enamel, caused by successive exposures to high concentrations of fluoride during tooth development,
leading to enamel with lower mineral content and increased porosity. The severity of dental fluorosis depends
on when and for how long the overexposure to fluoride occurs, the individual response, weight, degree of
physical activity, nutritional factors and bone growth. The risk period for esthetic changes in permanent teeth is
between 20 and 30 months of age. The recommended level for daily fluoride intake is 0.05 - 0.07 mg F/Kg/day,
which is considered of great help in preventing dental caries, acting in re-mineralization. A daily intake above
this safe level leads to an increased risk of dental fluorosis. Currently recommended procedures for diagnosis of
fluorosis should discriminate between symmetrical.....

Abstract:
Oral cavity cancer, or oral cancer, is a malignant tumor that starts in mouth. It is one of the most widely
recognized of all cancer which affects human beings. Oral cancer can be averted by staying away from tobacco
items, constraining liquor use, sun protection on the lower lip, HPV immunization, and evasion of paan. Oral
malignancy can be relieved at high rates with basic and practical medications, whenever distinguished at its
earlier stages. At earlier stages, Oral cancer can be automatically diagnosed. The basic aim of this "A Novel
Method for Automatic Detection of Early Stage Oral Cancer" is a simple, efficient and automatic oral cancer
detection system with the utilization of available software for non-specialists/clinicians/specialists. In this
approach, Pre-processing of image is performed by utilizing anisotropic diffusion filter for removing the noise
and enhancing the image quality.....

Abstract:
As the population is increasing rapidly, Energy demands also needs to be fulfilled efficiently, for that
supervision and monitoring of power system in various dynamic events have to be done precisely, Such tasks
are normally done by Supervisory control and Data Acquisition System(SCADA) and Phasor Measurement
Unit(PMU) also. PMU is best among all in terms of accuracy and time delaying as it uses Global Positioning
System for synchronization with other PMU's, and strong phasor estimation algorithm with less number of
samples giving accurate and real time tracking of power system in normal events as well as dynamic events.
This paper evaluates Modified Least square method for various dynamic events as per IEEE standard of
synchrophasor measurement. Morever dynamic events taken here are not model based signals, in earlier
literatures model based signals were used, that problem is eliminated in this paper..

- Comparing Natural Gas Energy Security in Asia and Europe:

Abstract:
According to the IMF (International Monetary Fund) , Asian economic growth is driving the world's economy,
accounting for more than 60% of the global economy. The Asian economy also accounted for more than 70% of
the world's increased energy demand from 2000 to 2017. According to WEO 2018 (World Energy Outlook
2018), issued by the IEA, Asia will account for 46% of total global energy demand in 2040. In a new policy
scenario (NPS), even in 2040, 74% of energy demandwill rely on fossil resources, of which 34% will be natural
gas. A key element of energy security in natural gas importing countries is the diversification of importing
partners. While natural gas diversification in Asia is advancing at a rapid pace, the diversity of natural gas
importers has decreased in recent years in some European countries. The 2015 Paris Agreement affected
countries using natural gas in many ways. Because of environmental measures taken in some European
countries,renewable energy has already becoming cheaper than natural gas in electricity market.........

Abstract:
The present work is focused on the numerical solution of unsteady two dimensional accelerating laminar
boundary layer flow and heat transfer of an incompressible fluid over a moving wedge in the presence of
variable viscosity. The system of partial differential equations governing the flow and reduced to a system of
non-linear ordinary differential equations by using similarity transformations, then solved numerically by an
implicit finite difference scheme along with quasilinearization technique. The obtained numerical results are
presented graphically in terms of velocity, temperature, as well as, for the skin friction and local nusselt number
for several values of variable viscosity parameter ( ) and Falkner-Skan parameter (m) along with Prandtl
number(Pr)..

Abstract:
The purpose of this project is to design and produce a miniature polymer granule extruder which can 3D print
just like a filament 3D printer with the same rate and quality. This project went through three different stages.
The first stage involved researching similar projects and different design ideas for the extruder. The second
stage consisted of designing a miniature polymer granule extruder using CAD software, in particular
SolidWorks, and then testing the design on a SolidWorks simulation before producing the extruder. During the
final stage, the practical stage, a prototype of the extruder was produced and then attached to the 3D desktop
printer to run tests on two materials: sugar and high-density polyethene (HDPE). A successful miniature
polymer granule should work as well as a filament 3D printer.

Abstract:
Unlike other water river basins in Morocco, Oum Er-Rbia basin is extensively used to meet both local and
regional water demands. Agricultural activities carried out within the basin account for 21% of the national
agricultural added value. Moreover, an additional 181 Mm3/year is transferred to neighboring basins, namely
Tensift and Bouregreg to come up with their water shortages. Besides, the basin surface water generates 70% of
national hydropower. Extensive use of both groundwater and surface water resources of this basin conjugated
with dry and wet years sequences have consequently compromised its role in securing the regional water
balance. In this work, statistical downscaling using SDSM was applied to predict future climate, particularly
temperature and precipitation, at the.....

Abstract:
Noise induced hearing loss (NIHL) is becoming a common occupational problem that affects
thousands of workers in Nigerian oil and gas industries. NIHL is a serious consequence of exposure to high
noise levels (>85dBA). In this study, a comprehensive approach, including noise survey, dosimetry and
audiometry, was employed to evaluate noise levels and hearing thresholds of workers in a typical oil and gas
industrial plant. The results obtained revealed a direct relationship between noise intensity and hearing loss
among workers. Workers whose noise levels were above the Occupational Safety and Health Administration
(OSHA) exposure limit of 90dBA were more prone to risk of hearing loss than workers whose noise levels were
below the limit. Hearing fit test data further suggest that hearing protection devices (HPDs) and human factors
such as physiology and skill in using HPDs, contribute....

Abstract:
Wireless communication is one of the most popular areas in the communication field today.
Development of next generation wireless networks depends on suitable wireless and access techniques. These
techniques needs to provide high data rates and should maintain a certain level of robustness against errors.
There are numerous challenges to implement these systems. These problems include propagation effects in
particular multipath propagation, capacity limits due to spectral availability, the need for asynchronous access,
Intersymbol Interference (ISI). Orthogonal Frequency-Division Multiplexing (OFDM) effectively mitigates
intersymbol interference caused by the delay spread of wireless channels. Therefore, it has been used in many
wireless systems and adopted.....
