Malaria has reemerged as a significant public health disease threat in Peru, especially within the Amazon Basin region. This resurgence of human cases caused by infection with Plasmodium falciparum and Plasmodium vivax is thought to be associated with the spread of Anopheles darlingi, the principal South American malaria vector, into new areas of the Amazon Basin. However, comprehensive studies...

The climate changes will be much more significant over the next 100 years and may lead to the heavy rainfall event. The heavy rainfall causes the flood hazard in the lowlands and geologic hazard in the mountains. Floods are also related to the changes in social economic conditions and land use. Recently, floods have been increasing due to rapid urbanization and human activity in the lowlands. T...

In the majority of lumped water balance models of river basins, groundwater is represented by a single reservoir, and groundwater discharge is described by a singlevalued function of storage in the reservoir. It is demonstrated that single-valued storagedischarge functions are often incapable of representing the actual storage-discharge characteristics of a river basin. An alternative discharge...

[1] We present estimates of nitrogen (N) inputs to the Changjiang River basin for the period 1968–1997. The total N input is approximately 7.8 10 kg in 1997, which is a threefold increase over 1968 levels. N fixation was often a dominant input before 1978, providing about 2.2 10 kg year , while N fertilizer dominated N input after 1983, supplying an additional input of some 4.4 10 kg year . Mor...

8 9 In order to determine the structure of the Chalk in the London Basin, a combined cognitive and 10 numerical approach to model construction was developed. A major difficultly in elucidating the 11 structure of the Chalk in the London Basin is that the Chalk is largely unexposed. The project had to 12 rely on subsurface data such as boreholes and site investigation reports. Although a high de...

[1] We present major, volatile, and trace elements for quenched glasses from the Fonualei Spreading Center, a nascent spreading system situated very close to the Tofua Volcanic Arc (20 km at the closest), in the northeast Lau Basin. The glasses are basalts and basaltic andesites and are inferred to have originated from a relatively hot and depleted mantle wedge. The Fonualei Spreading Center sh...

abstract evapotranspiration (et) determination is a key factor for irrigation scheduling, water balance, irrigation system design and management and crop yields simulation. therefore many scientists have tried to estimate evapotranspiration in different spatial and temporal scales. remote sensing is a one of new technique in estimation of et in regional scales. so, in this study it’s tried to e...

Design Based Research (DBR) is a new and still-emerging approach to research about design, learning, and allied areas. This article reports one designer’s experiences within a DBR project. Whereas most reports of DBR focus on the outcomes of the design itself, the current paper offers a hermeneutical perspective by focusing on the personal narrative of the designer. Using Edelson’s (2002) categ...
