editorial.pmd EDITORIAL i In this issue, we feature articles on applied mathematics, ecotoxicology, material science and engineering, and biodiversity. The diversity of data and information reflects the dynamism of the Science and Technology fields in the University. It is noteworthy that two of the articles featured in this issue are very relevant to current events in the country. The article on the “Optimized Drying Parameters of Water Hyacinths” describes the utilization of the aquatic plant that may clog the waterways. The article on the “Notes on Common Macro Benthic Reef Invertebrates of Tubbataha Reef Natural Park” reveals the probable damage brought about by the USS Guardian and, recently, a Chinese fishing vessel that ran aground in the World Heritage Site. All the articles in this issue show that developing countries like the Philippines practice science and technology that are significant to human endeavors. Again, this is a manifestation of the nationalism of our scientists and technologists. More power to them! MARCO NEMESIO E. MONTAÑO, PhD Editor-in-Chief
