The Cagayan State University is the largest state institution of higher learning in the Cagayan Valley Region, in terms of enrollment and number of curricular program offerings. The University was established through Presidential Decree 1436, later amended by Republic Act 8292 by the integration of all publicly supported higher education institutions in the province of Cagayan.The university is composed of eight campuses in the growth areas in the three congressional districts of Cagayan; the Aparri, Lal-Lo and Gonzaga campuses in the 1st District; the Piat, Lasam and Sanchez-Mira campuses in the 2nd District; and in the 3rd District, the Andrews and Carig campuses in Tuguegarao City. Each campus is headed by an Executive Officer except in Andrews Campus where the University President concurrently acts as the CEO. The seat of governance of the university is at the Andrews Campus, where the central administration holds office.The university offers courses in liberal arts, social science, law, medicine and allied professions, business and economics, natural science, engineering, technology, agriculture and fisheries and teaching, among others. It offers the most graduate and undergraduate courses of all the universities in the province of Cagayan.In March 2012, Dr. Romeo R. Quilang, former President of the Isabela State University , was elected by the CSU Board of Regents to serve as the CSU System's fourth president. Wikipedia.

Batch adsorption study was utilized in evaluating the potential suitability of chitosan-coated bentonite (CCB) as an adsorbent in the removal of indium ions from aqueous solution. The percentage (%) removal and adsorption capacity of indium(III) were examined as a function of solution pH, initial concentration, adsorbent dosage and temperature. The experimental data were fitted with several isotherm models, where the equilibrium data was best described by Langmuir isotherm. The mean energy (E) value was found in the range of 1-8kJ/mol, indicating that the governing type of adsorption of indium(III) onto CCB is essentially physical. Thermodynamic parameters, including Gibbs free energy, enthalpy, and entropy indicated that the indium(III) ions adsorption onto CCB was feasible, spontaneous and endothermic in the temperature range of 278-318K. The kinetics was evaluated utilizing the pseudo-first order and pseudo-second order model. The adsorption kinetics of indium(III) best fits the pseudo-second order (R2>0.99), which implies that chemical sorption as the rate-limiting step. © 2014 Elsevier B.V.

FM broadcast stations must transmit power only in areas where the signal is needed. This paper presents a simpler method of shaping the azimuth electric field pattern of an antenna system for FM broadcast applications to exhibit a radiation pattern similar to a directional desired radiation pattern without minor lobes. The method is simpler than the trial-and-error method of adding parasitic elements to achieve a certain desired pattern. It makes use of a uniform linear antenna array composed of two basic antennas or bays with omnidirectional pattern. Radiation patterns are realized by determining the optimum value of the distance between bays and their phase relationship. Genetic Algorithm (GA) is used in determining these optimum values assuring a radiation pattern that resembles the desired pattern. Some GA parameter values fitted for pattern shaping are first determined to improve accuracy and consistency before the GA optimization process is run. Two sample directional patterns are presented to demonstrate the performance of the method. Results show that the proposed method produces near zero cost function values resulting to radiation patterns having very close semblance to the desired pattern. An antenna simulation software is used to validate the results in each sample desired pattern. © 2011 Praise Worthy Prize S.r.l. - All rights reserved.

The per capita fish consumption in the Philippines has not significantly changed through the years (1987-2003), but the increase in human population has created an ever-increasing demand for food fish. The Philippine Bureau of Fisheries and Aquatic Resources has responded to the food fish shortage by promoting mariculture. We support this policy within a comprehensive planning and management framework that includes siting and density of mariculture facilities. The case of Bolinao-Anda, Pangasinan is presented in this article to highlight the multi-faceted process for a successful mariculture enterprise. We use remote sensing tools to track the responses of stakeholder groups to various local legislation, mariculture-induced disasters, and scientific recommendations. Using hydrodynamic models, we assess these responses and highlight potential adjustments that may alleviate the pressure on and maintain the ecosystem health of the Bolinao-Anda coastal waters. © 2014 Copyright © 2014 AEHMS.

In this study, Cu(II) removal under batch and fixed-bed conditions using chitosan-coated kaolinite (CCK) was investigated. The surface morphology of CCK was characterized using scanning electron microscopy. Batch experiments showed that 1:20 chitosan to kaolinite ratio can provide satisfactory Cu(II) removal. Kinetics study revealed that adsorption is best described by pseudo-second order equation (R2> 0.99). The isotherm data of Cu(II) adsorption using different ratios of CCK fitted well with Langmuir model (R2 > 0.98). The Langmuir constant, qmL has the following values of 11.2, 9.4 and 8.9 mg g-1 for 1:5, 1:10 and 1:20 chitosan to kaolinite ratio. In fixed bed studies, Cu(II) uptake increases and longer breakthrough time are attained as pH becomes more acidic. In addition, about 93% of Cu(II) removal from real groundwater system was attained using 2 g CCK.

The Philippines is one of the countries where adequate iodine status has been achieved. However, iodine deficiency still remains an important public health problem in this country. In this study, we evaluated iodine nutrition status and investigated an awareness status of iodine deficiency targeting high school students of Tuguegarao, Philippines. A total of 260 students provided samples for urinary iodine analysis, among which 146 students completed thyroid volume measurement by ultrasonography and answering the questionnaires. The median urinary iodine level was 355.3 μg/L and only 3.8% of the students were in the range of iodine deficiency status according to the ICCIDD criteria. Although 62.3% of students answered that they can list problems resulting from iodine deficiency, a majority of students (70.5%) were unable to identify problems other than goiter. They did not appreciate that adequate iodine levels are important during pregnancy and for development of children. 33.6% of students answered that they did not use iodized salt and the biggest reason was that they did not find it necessary. Based on these results, we suggest that a future strategy should be focused on vulnerable groups to completely eliminate iodine deficiency, including women at their reproductive ages and during pregnancy. © 2014 Bu Kyung Kim et al.
