Methods to predict the use of new technology at locations other than where experimental data exist also involved the use of spatially explicit analysis and the concept of geographic equivalence. First, the geographic characteristics of areas were identified in which experimental data existed on the performance of crops using new technology. Then, areas of geographic equivalence were identified ...

[1] Tide-induced variations in subsurface air pressure, mainly between 1.0 to 2.0 kPa, are observed in coastal areas in Hong Kong. A two-dimensional model which couples the two-phase air-water flow in unsaturated and saturated zones successfully reproduces the observed air pressure under no rain conditions. The simulation reveals that significant increases in air pressure depend on the tidal ra...

Schistosomiasis remains a global public health problem affecting about 240 million people. In Zambia, 2 million are infected while 3 million live with the risk of getting infected. Research and interventions relating to schistosomiasis are mainly linked to disease epidemiology. Malacological and ecological aspects of the disease are superficially understood. Developing effective control measure...

background: screening of students ´ health problems could lead to timely prevention and control of many health disorders. this study aimed to determine the nationwide prevalence of common disorders through school health screening program in iran methods: this cross-sectional national screening program was conducted in 2007-2008 among first- and third-grade- stu­dents in primary schools, first- ...

American tegumentary leishmaniasis (ATL) is a disease transmitted to humans by the female sandflies of the genus Lutzomyia. Several factors are involved in the disease transmission cycle. In this work only rainfall and deforestation were considered to assess the variability in the incidence of ATL. In order to reach this goal, monthly recorded data of the incidence of ATL in Orán, Salta, Argent...

This paper reports the preliminary results obtained from an FAO/IAEA coordinated research project (CRP) involving eight countries. Results obtained are discussed with respect to sources and sinks of water and nutrients in water conservation zones that help farmers to use water when it is required. Three types of water conservation zones, namely farm ponds, wetlands and riparian buffer zones wer...
