Abstract:
South American Monsoon Time Scale is proposed and designed by me
to study the South American monsoon. This is very useful to
study the South American monsoon. So scientists can make this
South American Monsoon Time Scale and make further research &
develop, promote & propagate it. Find out it by searching it’s
name South American Monsoon Time Scale in all websites or can
get by sending your email to
scientistgangadhar@yahoo.com
I call on world scientists to invent this scale and break down
the mysteries of the aforesaid monsoon. Scientists who want to
invent this scale have trouble in making it, kindly contact me
via my personal email id
gangadhar19582058@gmail.com
and take my assistance in making it. I will help you in making
this scale. A sample scale will also be made and send to you.
For this, a certain amount should be sent for expenses. For
this, they must send the list of events of climate just like
dust storms, monsoon low pressure systems etc. last 140 years
since 1880 formed over the South American monsoon region in the
procedure cited below reference. In addition to this, a certain
amount should be sent for expenses. You need to design the
computer model later.

Abstract:
According to
Einstein's
theory of
General Relativity,
space itself can be curved by mass. As a result, the density of
the universe —
how much mass
it has spread over its volume — determines its shape, as well as
its future. To put it in other words, if the cosmic triangle is
spherical, then the universe is closed; if it is hyperbolic then
the universe is open. In case the cosmic triangle is Euclidean,
then the universe is flat. In this brief work, by applying.

Kidney
Primarily from
Wikipedia, the free encyclopedia
(https://en.wikipedia.org/wiki/Kidney)
Mark Herbert, PhD
World Development Institute, 39
Main Street, Flushing, Queens, New York 11354, USA,
ma708090@gmail.com
Abstract:
The
kidneys are two bean-shaped
organs
found in
vertebrates.
They are located on the left and right in the
retroperitoneal
space,
and in adult humans are about 12 centimetres (41⁄2
inches) in length.
They receive blood from the paired
renal arteries;
blood exits into the paired
renal veins.
Each kidney is attached to a
ureter,
a tube that carries excreted
urine
to the
bladder.

nikebello73@gmail.com
Abstract:
Fruit shapes of
Pycnanthus angolensis were carried outto determine roundness
and ellipsoid ratios. Matured trees of Pycnanthus angolensis
(20.0±5.0years) were purposively selected from Osun (Gbongan,
Ajaba), Ekiti (Otun, Ayetoro) and Oyo (Idito, Adewumi) States,
based on availability. Fruit morphology was determined by
measuring weight (g), width (cm) and length (cm) of 100 samples
per location and was used to determine, roundness ratio and
ellipsoid ratio. Roundness ratio was derived using formular. The
largest diameter ranged from 3.6 to 5.0 and smallest diameter
ranged from 2.1 to 3.4, rounded fruits ranged between
116.0 to139.7 and
ellipsoid fruits ranged from 1.5 to 2.0.
Idito had the highest rounded ratio (139.7)
followed by Adewumi,
(134.8) and Otun (130.4).
Others were Gbongan (126.6),
Ajaba (126.2)
and last were Ayetoro (116.0).
With regards to their
ellipsoid ratio, the result showed that Ajaba had the highest (2.0)
level of ellipsoid followed by Gbongan 1.5 and Otun 1.6. Adewumi,
Ayetoro and Gbongan had similar ellipsoid ratio (1.5). The
fruits are rounded to ellipsoids, 3.6 - 5.0 cm x 2.1 - 3.4cm.
The Pycnanthus angolensis from Ajaba had the highest
ellipsoid fruits and Idito had the highest rounded fruits.

Abstract:
In this paper, modelling designing and simulation of a simple
voltage amplidyne system is done using robust control theory. In
order to increase the performance of the voltage amplidyne
system with H
optimal control synthesis and H
optimal control synthesis via
-iteration controllers are used. The open loop response of the
voltage amplidyne system shows that the system can
amplify the input 7 times. Comparison of the voltage amplidyne
system with H
optimal control synthesis and H
optimal control synthesis via
-iteration controllers to track a desired step input have been
done. Finally, the comparative simulation results prove the
effectiveness of the proposed voltage amplidyne system
with H

Abstract:
Gravity
or
gravitation is a
natural
phenomenon
by which all things with
mass
or
energy—including
planets,
stars,
galaxies,
and even
light—are
brought toward one another. Gravity is a physical connection
between
space
and
matter
that is precisely described by Einstein’s
geometric theory
of gravity.
In simple terms, the theory states that matter curves the space
around it, and it moves with respect to the curvature of space,
including curvature caused by other matter.

Abstract:
The objective of the present study was to access the “Attitude
of High and Higher Secondary School Students towards Physical
Education”. The present study was conducted on eight hundred
(500 male and 300 female) students between age group 16 to 20
years. The subjects were the students of High and Higher
Secondary Schools of North Kashmir, Jammu and Kashmir. To
examine the attitude of students toward Physical Education the
questionnaire developed by Claudia Cockburn (1999) was
administered on all the subjects. The responses collected from
the given subjects were converted into raw data with the help of
frequency distribution technique. The data was further tabulated
as results of the study through percentage method.

On the historical evolution
of panoramic technology and the analysis of the concept of
panoramic industry standards

Yitong Technology Company Limited
Abstract:
This article elaborates on the
history of panoramic technology and the concept of panoramic
industry standards. In the existing literature, it is difficult
to find very authoritative panoramic technology and industry
articles. Entering the 21st century, "Panorama" has quickly
entered the public's field of vision since 2010. An endless
stream of technology companies have invested a lot of capital,
manpower and material resources to promote panoramic technology
and panoramic products, including success and failure cases.
Panorama technology is moving from unpopular technology to mass
technology. In this process, it will encounter drastic changes
in user perception, technological innovation, and industrial
evolution. This requires us to objectively sort out the
development process of panorama technology, and then understand
the panorama from a global perspective. The effect of
technology.
