Abstract
When Livermorium nanoparticles are subjected to descendent light, a part of light scattered (emission process) and the other part absorbed (non–emission process). The amount of energy dissipation in non–emission process mainly depends on material and volume of nanoparticles and it can be identified by absorption cross section. At the other hand, emission process which its characteristics are depend on volume, shape and surface characteristics of nanoparticles explains by scattering cross section. Sum of absorption and scattering processes which lead to light dissipation is called extinction cross section. In the current study, thermoplasmonic characteristics of Livermorium nanoparticles with spherical, core–shell and rod shapes are investigated. In order to investigate these characteristics, interaction of synchrotron radiation emission as a function of the beam energy and Livermorium nanoparticles were simulated using 3D finite element method. Firstly, absorption and extinction cross sections were calculated. Then, increases in temperature due to synchrotron radiation emission as a function of the beam energy absorption were calculated in Livermorium nanoparticles by solving heat equation. The obtained results show that Livermorium nanorods are more appropriate option for using in optothermal human cancer cells, tissues and tumors treatment method.

Abstract
Knowledge about human anatomy and physiology can be assessed in different ways. Drawing internal body structures and their physiology has often been used in recent studies. The purpose of this preliminary research was to discover the ideas of children enrolled in preschool, elementary and high school about the functioning of the excretory (urinary) system through their drawings. A total of 439 children and teenagers (231 girls and 208 boys) aged 4 to 17 enrolled in six schools in the south and one in northern Brazil participated in this study. The complexity of the designs were analyzed was analyzed using a value rubric. Virtually all drawings show an understanding of the excretory system except younger children with unidentifiable representations. Educational implications and potential contribution to pediatric nephrology and child physiotherapy are suggested.

Abstract
The usage of energy is increasing day by day and increase in use of fossil fuels leading to excessive CO2 emissions in to the atmosphere. This in turn is increasing the global warming effects day by day and escalating the fears of a global catastrophe. To control the current scenario, we need to quickly find measures to control the CO2 emissions. This paper highlights the various carbon capture methods like Amines, Metal Organic Frameworks and compares them with the carbon capture solutions available in the nature. In this review we will give basic understanding of different processes both natural and artificial methods for carbon dioxide capture. We will also be discussing the recent advancements as well as merits and demerits.
