Industrial farm animals such as broilers housed in large tunnel-vent poultry system provide for a protein source of close to 100 million Filipinos. An efficient animal production facility, tunnel-vent system operates on a Climate Controlled System (CCS) which is controlled by a central computer. However, in the Philippines, there were recorded evidences of system malfunction and failure posing a great public concern due to obnoxious gases which inevitably attract household flies flocking nearby communities. This research delved on an in-depth study on the mechanism of operations of a tunnel-vent poultry production system in the northeastern part of the Philippines and used the baseline data to design, test and evaluate a prototype biofilter to mitigate odor as the GIST of the study. The designed simple, low-cost and environment-friendly prototype biofilter is made up of locally available materials. It is composed of a plenum, an exhaust fan and a supporting structure. The plenum is subdivided into four (4) drawers separated by screens to house filter media. Series of drawers was conceived in anticipation of choice and density of biomass filter materials. The exhaust fan which is 30.48 cm (12-in ø) operates on a suction mechanism which guides and pushes the air to pass through the filter media by as much as 230 cfm. The supporting structure provides for stability and protection of the biofilter and the exhaust fan. Performance evaluation showed positive and promising result. Thus, further study on upscaling and field testing of the biofilterin actual tunnel-vent system for odor mitigation is necessary. © 2017 WIT Press.

The lack of infrastructure for water treatment and distribution remains a major problem in many low-income regions across the globe. Many available water treatment technologies may not be successfully implemented due to economic constraints and low social acceptability. In this study, we test the extent to which Moringa oleifera (MO)-functionalized carbon biofilter columns can effectively remove bacterial contamination in water. MO proteins were adsorbed onto two carbon adsorbents, granular activated carbon (GAC) and rice husk ash (RHA), and were then used as packing materials for a biofilter column. Synthetic contaminated water (non-pathogenic E. coli in water) was fed at the top of the column at fixed flow rates, and coliform removal in the column was evaluated by monitoring the coliform breakthrough in the filtered water. A semi-factorial experimental design was adopted to evaluate the influence of column bed height, type of adsorbent, and contact time on the E. coli removal efficiencies. As a control, parallel experiments using bare carbon adsorbents were also performed. The effectiveness of MO-functionalized adsorbents was evaluated through ANOVA comparison of the breakthrough data from the experimental and control columns. Results show that the MO-functionalized adsorbents effectively remove E. coli from contaminated water. Generally, E. coli removal rates were higher in MO-functionalized RHA than in MO-functionalized GAC. These findings suggest the potential use of MO-based biofilters in water disinfection. Due to the low cost and availability of MO in many low-income regions, MO-functionalized adsorbents can be used as an inexpensive water treatment alternative in these areas. © 2017 IEEE.

Juveniles of the spiny siganid Siganus spinus were sampled from three sources in April, May and June 2008 for a study of its early life-history through otolith microstructure analysis. Specimens were obtained from bagnet catches in off-reef sites and seine nets in seagrass beds operating in Lagonoy Gulf, Philippines, and from the guts of skipjack tuna Katsuwonus pelamis caught by hand-line in an offshore area about 72 km east of the mouth of the gulf. The core, hatch ring, first feeding rings, and settlement increment of spiny siganid were identified and their widths measured. Mean daily otolith ages were 20.6, 22.1 and 21.7 of specimens from the gut, off-reef site and seagrass bed, respectively. Sagittae of the youngest (17-, 18- and 19-day-old) specimens from the tuna gut do not have settlement marks. Planktonic larval duration is 17 days. Most settlement (59%) occurred at the 20th increment on the evidence of its highest reduction in width and lessening of opacity. During the settlement process the juveniles swim from the fringing coral reefs to the seaweed beds then finally to the seagrass beds, wherein settlement volume is highest on or about the new moon date. The short, pelagic larval duration and restricted settlement timed on or 1-2 days near the new moon are integral elements in the settlement strategy of the fish. © 2010 Blackwell Verlag, Berlin.

Increased awareness on climate change causing fossil fuels created a global movement to produce and use ethanol. As a result, several regulatory standards coupled with financial incentives which support the use of ethanol have been implemented in the past decade. However, the selling price of ethanol in the global market is still not competitive due to its high processing costs. In an attempt to reduce the market price of ethanol, we test the extent to which rumen fluid obtained from slaughterhouse wastes can effectively convert cellulose into glucose. The hydrolase collected was filtered to remove inactive rumen microorganisms and this was subsequently fermented into ethanol. Control experiments were also performed to also assess the fermentability of the unfiltered hydrolase. A semi-factorial experimental design was adopted to evaluate the influence of initial rumen fluid concentration, initial rice hull dosage, and contact time on the glucose yield. Factor interactions and its effects on the glucose yield were assessed through two-way ANOVA comparison of the experimental data. Results show that the rumen fluid effectively hydrolyzed the cellulose into glucose. Even though a higher ethanol yield was observed for the filtered hydrolase, significant ethanol concentration produced in the unfiltered hydrolase indicated minimal inhibition of ethanol fermentation activity in solution. These findings suggest the potential use of rumen fluid in producing fermentable carbohydrates for the production ethanol. Due to the voluminous generation of slaughterhouse wastes annually, rumen fluid can be an inexpensive alternative source of cellulolytic enzymes that are essential for fermentation of glucose into ethanol. © 2017 IEEE.

Trends in health and well-being are taking the lead in the beverage consumption movement. The waning attractiveness of carbonated beverage may be attributed to the negative impression of the sugar content linking it to health problems. Studies show that coconut water is found to be as effective as a sports drink for rehydration. However, while coconut water may be an old commodity which is usually consumed as fresh, pasteurized coconut water (PCW) becomes a new entrant in the Philippine beverage industry. As a new player, penetrating the market of the giant beverage manufacturers seem to be risky and challenging. The study aimed to determine the market potential of bottled pasteurized coconut water and to identify product positioning opportunity in the beverage market. The study employed random consumption survey and product test. Van Westerndorp price sensitivity meter was used in determining the ideal price for PCW. The properties of PCW against the respondents' top beverage were used as bases for product positioning. The study revealed that PCW is widely accepted by the general consumers and the target market using common beverage attributes. PCW is positioned as a functional health drink that could serve as a substitute beverage to bottled water and sports drink. The natural and functional appeal of PCW may serve as its product differentiation tool in penetrating the beverage market and attracting consumers with active and healthy lifestyle. With high market acceptability, there is a huge potential for PCW to infiltrate the Philippine beverage industry.

Eichhornia crassipes (Mart.) Solms. plantlets were grown in 0.1 and 1.0 ppm treatment solutions of Hoagland’s hydroponic solutions modified with Hg(NO3)2 in order to examine the specific cellular and biochemical mechanisms involved in the tolerance of this plant exposed to mercury. This study assessed the responses of chloroplast pigments, i.e., carotenoids and chlorophylls, and evaluated the enzymatic and nonenzymatic antioxidant systems. Inductively coupled plasma-atomic emission spectrometry (ICP-AES) revealed varying Hg2+ levels in the young and mature leaf tissues, with greater amounts of Hg2+ found in the tissues of the young leaves. Total chlorophyll levels, notably those of chlorophyll a, chlorophyll b, and carotenoids, showed significant elevation in young leaf tissues, while a decrease in their levels was observed in mature leaf tissues in comparison to those of the control plants. These results lend support to the protective role of increased chlorophyll and carotenoid levels in the photosynthetic apparatus of young E. crassipes leaves in the presence of Hg2+. The antioxidant responses of Hg-treated E. crassipes plants were also measured, revealing a highly significant increase in catalase units, catalase and ascorbate peroxidase activities, and mercury-binding thiols in leaves from Hg-treated plants. Moreover, substantial differences in the degree of oxidative injury between the cells in leaves from the control and Hg-treated plants were evidenced by the lipid peroxidation activities monitored. The Hg-treatment-induced significant decrease in malondialdehyde (MDA) levels was observed in 0.1-ppm Hg(NO3)2-exposed plants, while a highly significant increase in MDA levels was noted in 1.0-ppm Hg(NO3)2-exposed plants. The high degree of lipid peroxidation at 1.0-ppm Hg treatment was evidently counteracted by the compensatory protective mechanism brought about by the increased levels in chloroplast pigments and the enhanced activities of the antioxidant systems. E. crassipes responded to mercury treatments by enhancing the synthesis of chlorophyll and carotenoid pigments, enzymatic, and nonenzymatic antioxidant substances, concomitantly increasing the antioxidative activities, thus rendering E. crassipes capable of tolerating Hg-induced stress. The potential of E. crassipes as a phytoremediator is evident. © 2014, Springer International Publishing Switzerland.

The effects of Moringa oleifera Lam. on the reproduction in male mice were studied. Twenty four male ICR mice divided equally into four groups were administered with the hexane extract of the leaves of M. oleifera by gavage at doses of 0.5, 5 and 50 mg/30 g BW daily for 21 days. The vehicle corn oil was used as control. Data on body weights, weights of reproductive organs, diameter of seminiferous tubule, stage of maturity, and levels of serum luteinizing hormone and follicle stimulating hormone were obtained and analyzed using one-way ANOVA and Tukey's test. Significant findings were: increased weights of testis (at medium and high doses); epididymis (at all doses); seminal vesicle (at the high dose) and also increased seminiferous tubule diameter (at all doses); increased thickness of epididymal wall (at medium and high doses); higher score for lumen formation (at the high dose) and epididymal maturity (at all doses). No significant effects on the level of the 2 hormones were obtained. © 2010 Academic Journals.

Association between air pollution and a multitude of health effects are now well established. Given ubiquitous exposure to some level of air pollution, the attributed health burden can be high, particularly for susceptible populations. In order to perform air quality measurements that are representative of a larger domain or a certain degree of pollution, a study on the air quality condition of the three main cities in the Bicol Region, namely; Legaspi, Naga and Iriga was conducted. The study focused on the parameters in determining air quality conditions. It also sought after the air condition in terms of Total Suspended Particulates (TSP) in the study areas and identified the main sources of the pollutants in the monitoring stations or observatories. The method used the comparative ex-post facto approach to compare and measure the total suspended particulate content in the three cities. The study revealed that the results are within the criteria, which means that the air is not yet dangerous to the health of the residents. Based on the emission inventory conducted by EMB Office from 2005, cars and utility vehicles were identified as the significant contributor of TSP. Burning of wood and dried leaves were primary sources of incomplete combustion in the stations. Carbon monoxide from vehicle exhausts is also a source of pollutant. In the light of the findings of the study, it is recommended that the residents in the subject cities must be aware of the Clean Air Act Program to comply with what they are expected to do, and be able to perform their duty on how to have a clean air and environment. A continuous implementation of the anti-smoke belching campaign as well as an intensified information and education advocacy will definitely help in the attainment of a better air quality in each city. © 2012 WIT Press.

Long-term, excessive harvesting of juvenile fish could lead to significant decline in their settlement strength. In the Philippines, the exploitation of siganid juveniles forms an important traditional fishery but no assessment of the exploitation status of such fishery had been made. The present study is a comprehensive assessment of the siganid juvenile fishery caught by bagnet in Lagonoy Gulf (Southeastern Luzon) by analyzing the temporal trend of their catch and effort statistics. Seven species of siganid juveniles composed the catch, which was dominated by Siganus canaliculatus (78%), S. spinus (8%) and S. argenteus (3%). Total catch 2001 through 2004 was 175 tonnes (t), 154 t, 130 t and 65 t, respectively. The total catch as well as the catch-per-unit-effort declined steeply in these 4 years. Juvenile occurrences or 'runs' were observed throughout the year except in some months in the later quarters of 2003 and 2004. Catches for all 4 years were always highest in April and May, occurring on or about the new moon mostly at the Albay East Coast. Overfishing must be stopped in order to prevent the collapse of this resource. © 2010 Blackwell Verlag, Berlin.

The use of visible and infrared bands, which have higher spatial resolution, is explored as an alternative to readily available satellite-derived rainfall estimates based on microwave and radar measurements. Data from the Moderate Resolution Imaging Spectroradiometer (MODIS) were used to develop the rainfall retrieval algorithm. Precipitating clouds were defined using the confident cloudy areas derived from MODIS cloud mask (MOD35) While cloud water path (CWP), cloud effective radius (CER), and cloud top temperature (CTT), which are all derived from the MODIS cloud (MOD06) products, were utilized as proxies to formulate rainfall estimate models. Regression analysis was applied using rainfall measurements from selected synoptic weather stations as training dataset. Among the models created, the model that best estimates the rainfall incorporates CWP, CER and CTT. This model has the highest R-square and the least root-mean-square error (RMSE).
