Submarine groundwater discharge (SGD) nutrient fluxes from un-sewered suburban landscapes pose a significant eutrophication risk to coastal waters. In unconsolidated coastal aquifers, nutrients recharged to groundwater undergo diffuse discharge to the coastline during SGD. Defining pathways of nutrient attenuation is required for land management professionals to take effective nutrient remediat...
Colombia's discharge fee system for water effluents is often held up as a model of a well-functioning, economic incentive pollution control program in a developing country. Yet few objective evaluations of the program have appeared. Based on a variety of primary and secondary data, this paper finds that in its first 5 years, the program was beset by a number of serious problems including limite...
We report here on the development of neutron and photon sources for use in imaging and active interrogation applications, where there is a growing urgency for more advanced interrogation tools. These devices include high yield D-D, D-T and T-T fusion reaction based neutron generators and also low energy nuclear reaction based high-energy gamma generators. One common feature in these various dev...
Storage battery is the integrant back power supply in the communication system, and its using life and security reliability are specially concerned by users. To avoid the accidents induced by the individual battery failure in the long-term using process, the running status of the storage battery must be maintained and monitored periodically. A new and advanced capacity measurement technology, i...
To investigate the role of the seepage zone in transport, chemical speciation, and attenuation of nitrogen loads carried by submarine groundwater discharge, we collected nearshore groundwater samples (n 5 328) and examined the distribution and isotopic signature (d15N) of nitrate and ammonium. In addition, we estimated nutrient fluxes from terrestrial and marine groundwater sources. We discuss ...
Less-frequent and inadequate sampling of sediment data has negatively impacted the long continuous records required for design operation hydraulic facilities. This data-scarcity problem is often found in most river basins Taiwan. study aims to propose a parsimonious probabilistic model based on copulas infill daily suspended loads using streamflow discharge. A copula-based bivariate distributio...
Whole-arm motor tasks performed by nonhuman primates have become a popular paradigm to examine neural activity during motor action, but such studies have traditionally related cell discharge to hand-based variables. We have developed a new robotic device that allows the mechanics of the shoulder and elbow joints to be manipulated independently. This device was used in the present study to exami...
