Translation and the Problem of Realism in Philippine Literature in English. Kritika Kultura, 23: 99-127, August 2014.

To the degree that Philippine literature in English is translational it cannot be realistic: realism is a signifying practice that presupposes a monocultural ground, upon which the “consensus” of representational fidelity can happen. And yet, much of the criticism of this literature, as produced by Filipinos themselves, has generally failed to take note of this crucial precondition, enacting a ruinous category mistake that, among other things, unwittingly confounds contemporary departures from the referential towards the “avant-garde” and/or antimimetic modes, as these are espoused by young Filipino poets and fictionists alike. Finally, this paper argues that the various literary practices encoded in Philippine anglophone writing still need to be postcolonially specified, their translated or syncretic qualities critically recognized and acknowledged, and that this kind of interpretive labor needs to be made not only by locally engaged critics but also by Filipino writers who purport to champion more theoretically informed and self-reflexive “performances” or texts.

Utilization of Moringa oleifera Leaf Meals as Plant Sources at Different Inclusion Levels in Fish Meal Based Diets Fed to Lates calcarifer. ABAH Bioflux, 6 (2): 158-167, July-December 2014.

Growth performance in terms of weight gain (%) and SGR showed that performance of the fish fed control diet and the test diet having 10% inclusion level of MOLM (MOLM-10) was highly significant to those fish fed with MOLM-20 and MOLM-30 dietary treatments (P<0.05). A number of studies showed that M. oleifera leaf meal could be used to substitute FM up to 10 % level in Clarias gariepinus (Ozovehe 2013) and this are also in agreement with the findings obtained by Tagwireyi et al (2008) for Oreochromis niloticus fry without any negative effects on the growth and feed efficiency.

On Subgroups of Crystallographic Coxeter Groups. Acta Crystallographica A- Foundation and Advances, 69: 445-451, July 2013.

A framework is presented based on color symmetry theory that will facilitate the determination of the subgroup structure of a crystallographic Coxeter group. It is shown that the method may be extended to characterize torsion-free subgroups. The approach is to treat these groups as groups of symmetries of tessellations in space by fundamental polyhedra.

Coincidences of a Shifted Hexagonal Lattice and the Hexagonal Packing. Acta Physica Polonica A, 126 (2): 516-519, August 2014.

Hexagonal lattices are represented by an array of dots wherein any three adjacent dots (that do not lie on a line) form the same equilateral triangle.  Suppose that a lattice is rotated (or reflected) about the origin.  If this rotated (or reflected) copy intersects the original lattice to form another lattice, then the intersection formed is called a coincidence site lattice (CSL).  CSLs are used to study geometric properties of grain boundaries.  By a grain boundary of a crystal, we mean the interface where crystallites of different orientations meet.  They are considered as structural defects of a crystal and may have effects on a crystal’s strength, thermal conductivity, and other properties.  The idea of CSLs has recently been extended for shifted lattices (i.e. lattices shifted by a fixed distance) and multilattices (i.e. unions of several shifted copies of a lattice).  In this paper, we first solve the coincidence problem for shifted hexagonal lattices.  We identify their CSLs and describe the rotations and reflections that generate such CSLs.  These results allow us to investigate the coincidences of the well-known hexagonal packing, or popularly called the “honeycomb lattice”.  The hexagonal packing turns out to be a multilattice that is formed by combining the hexagonal lattice with a certain shifted copy of it.  Using the multilattice framework together with a special case of the shifted hexagonal packing, we are able to solve the coincidences of the hexagonal packing.

Aedes aegypti Larvicide from the Ethanolic Extract of Piper nigrum Black Peppercorns. Natural Product Research, 29 (5): 441-443, 2015.

Catchy title of research: An active component of the DOST Ovicidal-Larvicidal Mosquito Traps determined.

The increasing number of dengue fever cases and deaths, especially among children, has long been a problem in our country. A few years back, the Department of Science and Technology (DOST) had introduced an ovicidal-larvicidal mosquito trap as a solution to decrease populations of the dengue virus vector (female Aedes aegypti mosquito). This OL traps had utilized P. nigrum peppercorns (commonly known as black pepper) as the larvicidal agent. As of the time that these OL traps were introduced, people only knew that black pepper contained larvicidal components but there has been no study yet that had identified these larvicidal compounds from the native black pepper found in the country. This study aims to identify the larvicidal components of local black pepper. Using extraction and chromatographic techniques, a compound was isolated. The compound’s larvicidal activity was verified by a modified version of the 2005 World Health Organization guidelines for laboratory testing of mosquito larvicides. Using spectroscopic techniques, we have identified that isolated compound as oleic acid. Thus, one of the compounds responsible for the larvicidal effect of P. nigrum against A. aegypti is oleic acid.
