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.

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 (412 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.

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.

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 optimal control synthesis controller in improving the percentage overshoot and the settling time.

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.

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.
