Oceanography also called oceanology or marine science‚ is the branch of Earth science that studies the ocean. It covers a wide range of topics‚ including marine organisms and ecosystem dynamics; ocean currents‚ waves‚ and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers blend to further knowledge

funds provided by companies thus giving corporations more power than the public. Although state regulators claim the water is safe to drink‚ the “wastewater contains cancer-causing chemicals as well as barium‚ which causes high blood pressure‚ and radium‚ which is radioactive” (Caruso‚ 2011). Therefore‚ corporations can buy power from the government regardless of the negative effects it may have on human life.

Sources of air pollution refer to the various locations‚ activities or factors which are responsible for the releasing of pollutants in the atmosphere. These sources can be classified into two major categories which are: Anthropogenic sources (human activity) mostly related to burning different kinds of fuel • "Stationary Sources" as smoke stacks of power plants‚ manufacturing facilities‚ municipal waste incinerators. Power plant is also used to refer to the engine in ships‚ aircraft and other

In this study‚ three different methodologies have been employed for the determination of 226Ra by means of liquid scintillation technique. The first one (referred to as "Rn-LSC-28" hereafter and the tables and figures) is based on the method of Prichard and Gessel (1977) and Cooper et al. (1988) and also used by Escobar et al. (1996)‚ Zouridakis et al. (2002) and Aleissa et al. (2012). In this procedure‚ 8 mL of each standard solution was transferred to a high density polyethylene vial‚ covered with

On December 7th we paused to remember the bombing of Pearl Harbor seventy-five years ago that began World War II. By the end of World War II‚ the nuclear bomb ushered in a whole new form of warfare. Due to the work of Otto Hahn‚ Lisa Meitner and Dr. Fritz Strassman‚ the creation of the atomic bomb would pave the way the world would look at war with the discovery of the process of nuclear fission. Otto Hahn traveled throughout Europe studying with some of the greatest scientists to develop nuclear

Isotopes‚ sub-atomic particles and relative atomic mass Sub-atomic particles A subatomic particle is a particle smaller than an atom: it may be elementary or composite. In 1905‚ Albert Einstein demonstrated the physical reality of the photons‚ hypothesized by Max Planck in 1900‚ in order to solve the problem of black body radiation in thermodynamics. In 1874‚ G. Johnstone Stoney postulated a minimum unit of electrical charge‚ for which he suggested the name electron in 1891. In 1897‚ J. J. Thomson confirmed
