Resorcinol/formaldehyde(RF)foam resin is an attractive material as a low-density target in high-power laser–plasma experiments because of its fine network structure,transparency in the visible region,and low-Z element(hydrogen,carbon,and oxygen)*** this study,we developed disk-shaped RF foam and deuterated RF foam targets with 40–200μm thickness and approximately 100 mg/cm^(3) density having a network structure from 100 nm to a few micrometers cell *** deuteration,the polymerization rate was drastically slowed down owing to kinetic isotope *** targets were used in high-power laser experiments where a megaelectronvolt proton beam was successfully generated.

Vertical Farming Using Hydroponic System: Toward a Sustainable Onion Production in Nueva Ecija, Philippines

Open Journal of Ecology 2018年第1期8卷 25-41页

The development of new technology for food production is essential to sustain man’s needs for survival. The use of farmlands for food production and industrial purposes goes beyond the carrying capacity of the environment. The study determined the applicability of Vertical Farming using Hydroponic Technology to onion production in Nueva Ecija, Philippines. The country is known as the onion capital of Southeast Asia. The study measured the technology’s sustainability and acceptability to onion farmers. By using experimental method, interview, and Focused Group Discussions (FGD), the study established its viability. Three phases of field experiments were conducted in August 2016, May 2017 and July 2017 using the Vertical Farming and Hydroponics Technology and Single Factor Analysis of Variance. The results showed that there is significant difference in the growth of onion bulb per week and the suitability and comparability of the technology to conventional farming. The study concluded that the VFH technology is acceptable to most onion farmers except the aspect of the cost of initial investment which requires government subsidy for the ordinary onion grower to avail of this new and sustainable technology in onion production.

Sustainability of E-Trike as Alternative Mode of Public Transportation System: The Case of Cabanatuan City, Philippines

引用

Open Journal of Civil Engineering 2017年第3期7卷 362-377页

作者： Felipe E. Balaria marilou P. Pascual Mercedes D. Santos Arjay F. Ortiz Arneil G. Gabriel Teodora Luz Soto Mangahas Nueva Ecija University of Science & Technology Cabanatuan City Philippines

The City of Cabanatuan is dubbed as the “Tricycle Capital of the Philippines”. Tricycle is a three wheeled vehicle used to transport people. Cabanatuan has about 30,000 registered gas-fed four-stroke motorized tricycles. Tricycle operation in this City has become the source of livelihood for around 10,000 families. Its number has tremendously increased despite growing competition and declining net daily income and the adverse effects it brings to the environment. The study analyzed the different aspects in the adoption of E-trikes (electric tricycles) as a mode of public transport system replacing motorized tricycles in the city. The conceptual framework of sustainable development was used to analyze the data. Basic accounting method in determining return on investment and payback period were used to compare the cost and return from among the current mode of transportation as against the adoption of E-trike. Data gathering employed the interviews, survey questionnaires and focus group discussion. The three areas of sustainability measured in the study were economic, socio-political and environmental. The study showed that from among 412 tricycle driver-operators randomly selected, majority were amenable to the shift from engine propelled tricycle to E-trike. However, cost of E-trike deters adoption and full implementation by the City Government. Political issue is also?the?utmost consideration since work displacement is imminent among the stakeholders once adoption of this mode takes place. On the other side, E-trike was found to be sustainable in the long run both on the point of view of operators and the riding public. The paper recommended that policy regulation be laid down, adopted, and implemented by the local government unit in response to the Philippines Cleaner Air Act.
