Flora Malesiana is a multi-volume flora describing the vascular plants of Malesia (the biogeographical region consisting of Indonesia, Malaysia, Singapore, Brunei, the Philippines, and Papua New Guinea), published by the National Herbarium of the Netherlands since 1950. It currently consists of 204 full treatments, covering about 20% of a total ...
If an atom has more electrons than protons, then it has an overall negative charge and is called a negative ion (or anion). Conversely, if it has more protons than electrons, it has a positive charge and is called a positive ion (or cation). The electrons of an atom are attracted to the protons in an atomic nucleus by the electromagnetic force.
Atomic units are chosen to reflect the properties of electrons in atoms, which is particularly clear in the classical Bohr model of the hydrogen atom for the bound electron in its ground state: Mass = 1 a.u. of mass; Charge = −1 a.u. of charge; Orbital radius = 1 a.u. of length; Orbital velocity = 1 a.u. of velocity [44]: 597
Particle physics or high-energy physics is the study of fundamental particles and forces that constitute matter and radiation.The field also studies combinations of elementary particles up to the scale of protons and neutrons, while the study of combination of protons and neutrons is called nuclear physics.
The establishment of this committee was based on the many nuclear tests carried on in the 1950s by several countries, especially the United States, in different regions of the Pacific, that have given rise to the concerns of radioactive material falling in parts of Indonesia. The task of this committee was to investigate the effect of nuclear ...
Environmental issues due to Indonesia's rapid industrialisation process and high population growth, have seen lower priority given to preserving ecosystems. [3] Issues include illegal logging, with resulting deforestation, and a high level of urbanisation, air pollution, garbage management and waste water services also contributing to the forest deterioration.
Thaumatophyllum bipinnatifidum (common names: split-leaf philodendron, [1] lacy tree philodendron, selloum, horsehead philodendron, [2] guaimbé [citation needed]) is a plant in the genus Thaumatophyllum, in the family Araceae.
The program for nuclear power in Indonesia includes plans to build nuclear reactors in the country for peaceful purposes. Indonesia prohibited development of nuclear weapon or any offensive uses due to signing the Treaty on the Non-Proliferation of Nuclear Weapons on 2 March 1970 and ratified it as Law No. 8/1978 on 18 December 1978.
