Maria Ines Rosana D. Balangue-Tarriela National Institute of Geological Sciences College of Science UP Diliman Geology, Alteration, and Mineralization of the Kay Tanda Epithermal Gold Deposit, Lobo, Batangas, Philippines, Resource Geology, 69 (4): 351-384, 2019 The Philippine Archipelago is dotted with numerous ore deposits of different types, including but not limited to laterite deposits, massive sulphides, porphyry copper deposits and epithermal Au deposits. The Kay Tanda mineral deposit in Batangas province is one of the least studied Philippine epithermal deposits. Epithermal deposits are formed by hot circulating solutions with temperatures not more than 300degC (hydrothermal fluids) depositing metals ( gold, […]

Jose P. Peralta1, Lhumen A. Tejano1 and Honey Lyn R. Gomez1 1Institute of Fish Processing Technology, College of Fisheries and Ocean Sciences (UP Visayas) True Bulk As-antisite Defect in GaAs(110) Identified by DFT Calculations and Probed by STM/STS Measurements, Applied Surface Science, 511: 145590, doi: 10.1016/j.apsusc.2020.145590, 2020 Most people nowadays are suffering from different health problems (hypertension, diabetes, cancer, etc.,) even at a very young age. To control/ minimize the occurrence of these diseases, synthetic drugs have been developed and administered to patients. However, these synthetic or “unnatural” drugs have caused some negative effects such as cough, skin rashes, taste […]

Josefina T. Dizon Institute for Governance and Rural Development College of Public Affairs and Development UP Los Baños Water Governance Framework in Sta. Cruz River Watershed, Laguna, Philippines, Journal of Environmental Science and Management, 22(1): 54-66, 2019 Deforestation due to illegal cutting, charcoal making, quarrying, mining, and destructive farming practices resulted to insufficient water supply for irrigation in the Sta. Cruz River Watershed. Since the National Irrigation Administration has transferred to the Irrigators’ Association (IA) the ownership of the irrigation system, the model proposes that the IA plays a central role in the management of the irrigation system. Thus, its leadership, […]

Gilbert R. Peralta Department of Mathematics and Computer Science College of Science UP Baguio Analysis of a Nonlinear Fluid-Structure Interaction Model with Mechanical Dissipation and Delay, Nonlinearity, 32: 5110-5149, 2019 The interaction between a solid and a fluid has been studied extensively in the past decades. Applications typically arise in several engineering designs and blood flow models. The research takes into account a model where there is a delay in the feedback control on the structural component. This entails that there is a time-lag for the control to be effective. It is known that delays can lead to instability. Nevertheless, the […]

Ong2 1Environmental Engineering Program, College of Engineering (UP Diliman) 2School of Technology (UP Visayas) Optimization, Isotherm, and Kinetic Studies of Diclofenac Removal from Aqueous Solutions by Fe-Mn Binary Oxide Adsorbents, Environmental Science and Pollution Research, 26: 32407–32419, 2019 This study focused on the removal of diclofenac (DCF), a widely used non-steroidal anti-inflammatory drug, from aqueous solution using Fe–Mn binary oxide (FMBO) adsorbents. The selected FMBO combination takes advantage of the superior adsorption ability of iron (III) oxide and the excellent oxidation potential […]

Karlo de leon1, Michael Francis Ian G. Vega II1 1National Institute of Physics, College of Science (UP Diliman) Weak Gravitational Deflection by Two-power-law Densities Using the Gauss-Bonnet Theorem, Physical Review D, 99 (12): 124007, 2019 Light rays bend around galaxies. In general relativity, the presence of mass curves spacetime, and this curvature bends light. Every galaxy then, depending on how mass is arranged inside it, has its own signature on how it deflects light. This allows us to “see” how mass may be distributed in a galaxy just by looking at how it deflects light around it. Knowing this is important […]

Margaret M. Calderon Institute of Renewable Natural Resources College of Forestry and Natural Resources UP Los Baños The Effects of Petroleum Product Price Regulation on Macroeconomic Stability in China, Energy Policy, 132: 96-105, 2019 Petroleum products are important to all countries – various sectors of society have become dependent on these products for all kinds of economic activities. The growing scarcity of fossil fuel has resulted in increasing petroleum product prices (PPP), and countries closely monitor fluctuations in world crudeoil prices (WCOP), especially when there are world oil price shocks. China is no different, and it has undertaken measures to regulate […]

Galay Department of Veterinary Paraclinical Sciences College of Veterinary Medicine UP Los Baños Induction of Intracellular Ferritin Expression in Embryo-derived Ixodes Scapularis Cell Line (ISE6), Scientific Reports, 8 (1): 16566, 2018. https://doi: 10.1038/s41598-018-34860-3 Ticks are obligate blood-sucking parasites of humans and animals that also transmit various diseases. Due to their feeding habit, ticks are exposed to large amount of iron. Iron is an essential trace mineral, but it is toxic in large amounts. Hence, iron metabolism is crucial in tick survival. Ferritin and iron-regulatory protein (IRP) are among the molecules involved in iron metabolism. This study investigated the induction […]
