Saturday, October 22nd, 2011The preparation of ethanol from cellulose-, starch-, and sugar-containing raw materials involves the following general steps: Pretreatment-the physical or chemical conversion of the raw material to a hydrolyzable substrate. Hydrolysis-the enzymatic reaction that converts the starch or cellulose to sugars. Yeast fermentation-the conversion of sugars to ethanol and carbon dioxide. Purification-the separation of ethanol from [...]
Golden Rice battles blindness
Friday, October 21st, 2011AS someone who spends long, unpredictable hours in developing Golden Rice, scientist Dr. Antonio Alfonso has been described by his colleagues at the Philippine Rice Research Institute (PhilRice) as “Mr. Patient.” Alfonso was tapped as early as 2004 to lead a research team that will develop the world’s first vitamin A-fortified, genetically modified (GM) rice [...]
GM mosquitoes mulled vs dengue
Thursday, October 20th, 2011A DENGUE scare occurred in the Philippines in the last couple of months what with the big number of cases and harrowing testimonies of dying patients reported in the media.

Clean water for evacuation centers, lotion vs dengue at young inventors’ exhibit
Thursday, October 20th, 2011MORE than 450 young Filipino inventors and professionals exhibited their inventions that aim to help address some major concerns in the country. Technological University of the Philippines (TUP) College of Electronic Engineering Technology third year students presented a prototype that would give clean drinking water and lightning system with the use of solar energy in [...]
Health-promoting approach to tap Philippine indigenous plants
Saturday, October 15th, 2011The Philippines is home to at least 13,500 species of higher vascular plants, indicating the high variety and variability of living organisms in this country. It holds the reputation of being the only country in the ASEAN region identified as a biodiversity hotspot (ACB, 2009). With this distinction, it is not difficult to imagine that [...]

Brick Clamps
Wednesday, October 12th, 2011Introduction The use of brick clamps is by far the oldest and most rudimentary method of firing bricks. When “scoved” (that is, plastered on the outside for greater efficiency), they become scove clamps or kilns. If the clamp is enclosed within four permanent walls, it becomes a rectangular Scotch kiln, but in its most basic [...]

Rural schools may not have enough paper for their students and market goods may be wrapped in old newspapers if at all. Often this is because resources are not available to invest in modern papermaking factories, which require large amounts of energy and raw materials [...]
Boat Design, Construction, and Propulsion
Saturday, October 8th, 2011Traditional fishing vessels have evolved to complement the sea conditions and fishing methods unique to each particular region. Like fishing gear, boats have passed the test of time. Nevertheless, traditional craft are not without their problems. They often have a very limited range of operation and are not able to go beyond heavily fished nearshore [...]
Fisheries Technologies for Developing Countries
Thursday, October 6th, 2011Overview Many of the fishermen in developing countries are locked into economic systems that result in relative poverty. Although the technologies they use have evolved in accord with indigenous biological resources and socioeconomic realities, there may be opportunities for improvement. Existing technologies from other developing regions might be transferred to these fisheries and some of [...]
