We utilized biodiversity indices and multivariate techniques to investigate the relationship between environmental conditions and net phytoplankton composition and abundance during early (November) and mid (February) northeast (NE) monsoon, intermonsoon (May), and southwest (SW) monsoon (August) in Panguil Bay, an exploited mangrove estuary in Northern Mindanao, Philippines. Phytoplankton were composed of diatoms, dinoflagellates, and cyanobacteria. The centric diatom Coscinodiscus wailesii was the most common, but outnumbered by the chain-forming diatom Thalassionema frauenfeldii in SW monsoon. The harmful algal bloom dinoflagellate Ceratium furca became common in the warmest intermonsoon month of May, but its numbers did not reach bloom level. Two distinct assemblages (deeper, more saline, low abundance but high diversity stations located near the mouth of the bay, and shallower, less saline, high abundance but low diversity inner stations) appeared to oscillate horizontally with NE and SW winds. Depth, tide, and monsoon-related variables (total suspended solids, salinity, and dissolved nitrates) significantly influenced changes in phytoplankton community structure in Panguil Bay. © International Society for Tropical Ecology.

A multivariate analysis of stomach contents was used to investigate the trophic ecology of nighttime-collected Acetes intermedius in 2 adjacent near-shore estuaries in Iligan Bay, northern Mindanao, the Philippines from Feb. 1999 to Jan. 2000. Thirteen diet categories were observed indicating that A. intermedius is an omnivorous zooplanktivore with copepods, ostracods, decapod crustacean larvae, gastropod and bivalve veligers, and amorphous materials as dominant food items. Juveniles, however, showed a predominance of amorphous and fine materials. A linear ordination redundancy analysis showed that peak abundances of different dietary items coincided with monthly rainfall and sea surface temperature. The most common prey item of copepod fragments dominated in Mar. to June, months with high rainfall and warmer seas. Other common prey items, ostracods, bivalve and gastropod veligers, decapod crustacean fragments, chaetognaths, and tintinnids were correlated with cooler months from July to Nov. Peaks of most common ingested prey items were associated with dominance of equivalent zooplankton categories. The present study demonstrates that this species occupies an environmentally cued omnivorous feeding niche between lower-trophic-level plankton, particularly mesozooplankton, and higher predators in the pelagic zone of Iligan Bay.

This paper presents a digitally controlled way of generating the sinusoidal signal with less memory consumption. Moreover, this paper also presents a new switching frequency modulation technique. This technique utilizes the concept of spread spectrum frequency modulation that is used to suppress the electromagnetic interference (EMI) caused by high switching frequencies. Measurement results at the output sine pulse-width generation show that when the spread spectrum technique was applied to the conventional triangular wave and the fundamental, second, and third harmonics of switching frequency were reduced, respectively, by 12.8, 11.2, and 16.4 dB trading off with the slight increase in total harmonic distortion (THD) of 0.092% from a THD of 2.34%. While in the inverter output, there was a 14-dB reduction in EMI peak in exchange to 0.12% increase in THD from a THD of 2.57%. © 2005-2012 IEEE.

Although Acute Stress Disorder (ASD) was introduced in the Diagnostic and Statistical Manual of Mental Disorders, fourth edition for a number of years already, only few studies have examined ASD in its latent level. Utilizing 998 respondents who experienced a deadly flashflood, the results revealed that of the 7 models, Dysphoric arousal model fitted best whereas the new DSM-5 single factor model received the lowest fit. The findings of the study are pertinent in the current changes of ASD in DSM-5 and would elucidate further ASD’s latent structure that best represent Asian sample, particularly Filipinos. © 2015, Springer Science+Business Media New York.

In the Philippines, some laws and regulations concerning chemical safety and security do exist. However, in general, an effective system of enforcement is still lacking. Moreover, chemical safety and security concerns are not a high priority, at least, especially in most state-run academic institutions. This paper explores the safety and security practices presently used in some state and private universities in Mindanao, Philippines. The Mindanao region has been considered a hot-bed of terrorism in the Philippines which makes security a main concern even in the academe. Although these universities generally use chemicals in typically small quantities, they are still considered a vulnerable target for chemical theft and diversion. The security measures currently employed as well as the needs and difficulties encountered to improve chemical safety and security practices are discussed. © 2011 Division of Chemical Health and Safety of the American Chemical Society.
