1. Traditionally the assessment of river water quality has been based solely on the measurement of physical, chemical and some biological characteristics. While these measurements may be efficient for regulating effluent discharges and protecting humans, they are not very useful for large-scale management of catchments or for assessing whether river ecosystems are being protected. 2. Measuremen...

An independent Science Advisory Panel (The Panel) was formed to assist the Alaska Department of Environmental Conservation evaluate the effects of wastewater discharges from cruise ships in Alaskan waters. The Panel evaluated the dilution of wastewater discharges from moving cruise ships. The results of that evaluation were used in turn to evaluate possible effects on water quality. This paper ...

Our long-term goal is to determine if submarine groundwater discharge (SGWD) is an important mechanism for delivering contaminants (i.e. heavy metals, organics) to harbors. We plan to accomplish this goal using a suite of naturally-occurring radium isotopes as tracers of SGWD and the dispersion of contaminants from the embayment (Buesseler/WHOI). In addition, we plan to develop a comprehensive ...

In both humans and animals brief synchronizing bursts of epileptiform activity known as interictal epileptiform discharges (IEDs) can, even in the absence of overt seizures, cause transient cognitive impairments (TCI) that include problems with perception or short-term memory. While no evidence from single units is available, it has been assumed that IEDs destroy information represented in neur...

BACKGROUND AND PURPOSE Comprehensive multicenter data on treatment of pediatric moyamoya in the United States is lacking. We sought to identify national trends in the diagnosis and treatment of this disease. METHODS A total of 2454 moyamoya admissions from 1997 to 2012 were identified from the Kids Inpatient Database. Demographics, inpatient costs, interventions, and discharge status were ana...

The formation of particles in low-pressure silane discharges has been studied extensively over the last decade. In this paper we try to identify, by numerical simulations, the precursors of the dust formation and we examine the gas-phase reactions leading to larger clusters, and finally to nanometer or micrometer sized particles. A one-dimensional fluid model is used, which incorporates silicon...

MRSA was isolated from pus, urine, breast discharge, blood culture, cerebrospinal fluid, and ascetic fluid [2]. The extensive use of antibiotics over the last 50 years has led to the emergence of bacterial resistance and to the dissemination of resistance genes among pathogenic organisms [3]. In addition, since few cells in a population might actually express resistance, these heterogeneous str...

We quantified groundwater discharge and associated nutrient fluxes to Monterey Bay, California, during the wet and dry seasons using excess (224)Ra as a tracer. Bioassay incubation experiments were conducted to document the response of bloom-forming phytoplankton to submarine groundwater discharge (SGD) input. Our data indicate that the high nutrient content (nitrate and silica) in groundwater ...
