Transuranium element

Transuranium element, any of the chemical elements that lie beyond uranium in the periodic table—i.e., those with atomic numbers greater than 92. Twenty-six of these elements have been discovered and named or are awaiting confirmation of their discovery. Eleven of them, from neptunium through lawrencium, belong to the actinoid series. The others, which have atomic numbers higher than 103, are referred to as the transactinoids. All the transuranium elements are unstable, decaying radioactively, with half-lives that range from tens of millions of years to mere fractions of a second. Since only two of the transuranium elements have been found in nature (neptunium and plutonium) and those only in trace amounts, the synthesis of these elements through nuclear reactions has been an important source of knowledge about them.

Neutron capture

It is believed that these heavier elements, and some isotopes of lighter elements, have been produced by successive capture of neutrons. Two processes of neutron capture may be distinguished: the r -process, rapid neutron capture; and the s -process, slow neutron capture. If neutrons are added to a stable nucleus, it is not long before the product nucleus becomes unstable and the neutron is converted into a proton. Outside a nucleus, a neutron decays into a proton and an electron by a process called beta decay (β-decay). Inside a nucleus it can be stable if the nucleus does not contain too many neutrons. In slow neutron capture, neutrons are added at a rate such that whenever an unstable nucleus is formed, it beta-decays before another neutron can be added. If neutrons can be added more rapidly, as in the r -process, the unstable nuclei formed cannot decay before additional neutrons are added until a nucleus is eventually produced that will not accept a further neutron. This nucleus, however, will eventually be subject to beta decay, thus permitting further neutron capture.

Computer architecture, structure

Computer architecture, structure of a digital computer, encompassing the design and layout of its instruction set and storage registers. The architecture of a computer is chosen with regard to the types of programs that will be run on it (business, scientific, general-purpose, etc.). Its principal components or subsystems, each of which could be said to have an architecture of its own, are input/output, storage, communication, control, and processing. https://aap-qa.apps.venturit.org/playlist/education-systems

Conservation of Water

Water is one of the basic necessities for every living being and we cannot imagine a life without water. It is the natural resource and the main constituent of our planet earth. Water is the universal solvent and plays a key role in the existence of various forms of life on the planet earth. It is widely used for various purposes such as washing, bathing, cleaning, cooking, drinking, and other industrial and domestic uses. Water is a colourless and odourless substance that is essential for the survival of living beings. There are various sources of water such as wells, rivers, ponds, lakes, oceans, big dams, and streams. As we all know, nearly 70 to 80 percent of the Earth’s surface is covered by water, among which only 1-2 per cent water is pure and suitable for human use. Conservation of water mainly refers to protect, preserve, and control the usage of water and its resources. It is the system introduced to manage freshwater, reduce the wastage and protect the water and its resources in order to reduce and to avoid the scarcity. Therefore, we all should come forward to create awareness about conservation of water among our own friends, family, neighbours, society, etc. Conservation of water is very much essential as it saves life on earth.

The atomic nature of the elements

Paralleling the development of the concept of elements was an understanding of the nature of matter. At various times in history, matter has been considered to be either continuous or discontinuous. Continuous matter is postulated to be homogeneous and divisible without limit, each part exhibiting identical properties regardless of size. This was essentially the point of view taken by Aristotle when he associated his elemental qualities with continuous matter. Discontinuous matter, on the other hand, is conceived of as particulate—that is, divisible only up to a point, the point at which certain basic units called atoms are reached. According to this concept, also known as the atomic hypothesis, subdivision of the basic unit (atom) could give rise only to particles with profoundly different properties.

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly—the natural satellites—two are larger than the smallest planet, Mercury. One of Billions. Our solar system is made up of a star, eight planets and countless smaller bodies … Meet Me in the Orion Arm. Our solar system orbits the center of the Milky Way Galaxy at about … A Long Way Round. It takes our solar system about 230 million years to complete one orbit around … Spiraling Through Space. There are three general kinds of galaxies: elliptical, spiral and irregular.
