Calcium‚ Magnesium‚ and Cytoplasmic Streaming in Physarum Polycephalum Eugenia Rita Lee Dr. Bonner BIO 111 Introduction: Physarum polycephalum is a type of slime mold of the myxogastria class that prefers warm and damp conditions. It can go through three forms‚ plasmodium‚ sclerotium‚ and sporangia. The plasmodium is the primary active state‚ where P. polycephalum consists of protoplasmic veins and multiple nuclei. During this stage‚ the slime mold surrounds its’ food and secretes enzymes

Chapter 1 From X-Rays to Ion Beams: A Short History of Radiation Therapy James M. Slater Abstract Radiation therapy (RT) developed in several eras. Patients’ needs for more effective treatment guided the efforts. The development of ion beam therapy (IBT) can be seen as a corollary in this continuous endeavor to optimize disease control while minimizing normal-tissue damage. It could not have materialized‚ however‚ without the curiosity‚ ingenuity‚ and perseverance of researchers‚ engineers

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.
