News of recent publications by Filipino researchers
YBa2Cu3Oy (YBCO) belongs to a class of oxide materials collectively referred to as “high-Tc (critical temperature) superconductors (HTS),” i.e., materials that exhibit superconductivity above the boiling point (77K) of liquid nitrogen. However, as these materials are typically brittle, in order to be used for potential applications they have to be processed into a useable form,…
In a recent paper entitled “Research productivity in education and psychology in the Philippines and comparison with ASEAN countries” published in Scientometrics, Lorelie Vinluan (University of the Philippines, Diliman) examined the country’s research productivity in the field of education and psychology. This type of study is important as it will help determine available experts in…
The law of reflection states that with respect to an imaginary line that is perpendicular to the surface of the reflecting object, light will be reflected at the same angle and at the same plane as it was incident. Euclid, writing in Catoptrics, already had a mathematical description of this law in 300 BC [1]. In the…
Several years ago, we reviewed the scientific publication performance of the Philippines and some of its neighboring countries including Indonesia, Malaysia, Thailand, and Vietnam. Using the Science Citation Index Expanded, we looked at the number of publications coming from these countries between 1980 and 2006. See Box 1. Our findings showed that Malaysia and Thailand…
Post contributed by Dr. Elmer Estacio, currently affiliated with the Far Infrared Center, University of Fukui. His area of research is on MBE-grown terahertz semiconductor emitters and development of high-speed terahertz time-domain spectroscopy techniques. The terahertz (THz, 1012 Hz) frequency region bridges the gap between electronics (microwave band) and photonics (IR and visible light bands).…
Dengue fever is a mosquito-borne viral disease that’s becoming an increasing problem in tropical and subtropical regions. It is an infection that causes a severe influenza-like illness, and sometimes a deadly complication called dengue haemorrhagic fever. Some of the symptoms of dengue include sudden onset of high fever which may last 2 to 7 days,…
Recently, there has been a growing interest in finding alternative forms of energy. This is mostly driven by increasing prices of oil, concerns over greenhouse gases emission from fossil fuels, and some form of government subsidies. One of the alternatives which has been gaining much public and scientific attention is biofuel, a type of fuel…
To understand better the possible effects of climate change in the Philippines, it is critical to collect, record, collate and analyze all data and information with possible links to climate change so that appropriate scenario-building and extrapolations can occur. The Philippines, being an archipelago and a developing country, is highly vulnerable to the adverse impact…
With the reproductive health bill currently under consideration in Congress, issues regarding population and family planning has recently received heightened media coverage. In a recent paper entitled “News framing of population and family planning issues via syntactic network analysis” appearing in the International Journal of Modern Physics C, Legara and colleagues, all researchers from the…
