Ingestion Rates of Five Species of Pacific Northwest Echinoderm Larvae on Natural and Artificial Particles
Ingestion rates for five species of echinoderm larvae, the sea stars Dermasterias imbricata, Pisaster ochraceus, and Evasterias troschelii, the sea urchin Strongylocentrotus purpuratus, and the sand dollar Dendraster excentricus, were investigated by assigning larvae to three natural and one …

Grazing on <i>Synechococcus spp.</i> by the Red-Tide Dinoflagellate <i>Karenia brevis</i>: Implications for Bloom Dynamics in the Gulf of Mexico
… isolate. Maximum <em>K. brevis</em> ingestion rates were measured within the first 2 to 6 hours in laboratory incubations augmented with <em>Synechococcus</em> prey and rates ranged from 7.2 to 48.0 <em>Synechococcus K. brevis</em><sup> -1</sup> hr<sup>-1</sup>. I calculated a lower …

Nutritional regulation of egg production of Calanus Finmarchicus in the North Atlantic
… in situ conditions to determine egg production rates and the ingested quantities of C, N, EPA and DHA. Biomass contributions towards growth were determined and the biochemical composition of the eggs was examined. In order to accurately determine ingestion rates, a method to account for …

Adaptive batching of streams to enhance throughput and to support dynamic load balancing
… such as server load variation, changes in data ingestion rates, and workload characteristics. In this thesis, we explore the effects of the batch size on the performance of streaming workloads by developing an adaptive batching framework and building load-balancing algorithms on top of this …

Empirical Evaluation of Edge Computing for Smart Building Streaming IoT Applications
… performance and (2) enables processing of higher ingestion rates by eliminating network bottleneck.

Zooplankton abundance, community composition and grazing in the James River Estuary (Virginia, USA)
… abundance, community composition and grazing rates were assessed at three locations which included a site with high algal production (near the VCU Rice Center) and two sites where algal production was lower. Grazing rates were measured by determining the rate of phytoplankton decline (as …

Contextualization and Sodium Diet Implications of Occoquan Reservoir Salinization
… varied due to the wide range in drinking water ingestion rates. The purpose of these analyses is to assist with stakeholder convergence around the level of threat salinization poses to the reservoir and to initiate discussions of what an acceptable threshold for management could be.

Application of a Non-intrusive Optical Non-spherical Particle Sizing Sensor at Turboshaft Engine Inlet
Particulate ingestion has been an ongoing issue in the aviation industry as aircraft are required to operate in hostile environments. Ingesting particulates such as sand or dust can erode and damage engine components. This damage will affect the life cycle of parts and compromise the safety of the …

Microbial risk assessment for recreational use of the Kallang Basin, Singapore
… level based on appropriate dragon-boat racer ingestion rates. Statistical analysis showed that a high correlation existed between adenovirus concentrations and E. coli concentrations. Future studies should analyze specific locations along the Kallang Basin that contribute to high …

Carbohydrate intake and metabolism during prolonged endurance exercise
It is well accepted that CHO ingestion can improve endurance performance. However, a number of questions remain open regarding fine-tuning CHO intake recommendations during prolonged endurance events. A way to measure the bioavailability of ingested CHO is to measure exogenous CHO oxidation with …

Investigation of prey ingestion and digestion in the ciliate predator Tetrahymena pyriformis and the impact on growth
… evaluated the effect of four prey states on ingestion, digestive vacuole (DV) formation, digestion and growth in the ciliate Tetrahymena pyriformis. The prey included several strains of live RFP-expressing heterotrophic bacteria (Live), heat-killed-DTAF-stained heterotrophic bacteria (Dead), …

The ecology and feeding biology of thecate heterotrophic dinoflagellates
… was known about their feeding mechanisms, rates or food preferences. The population dynamics of these microheterotrophs were studied in a temperate estuary over a 13 month period, along with co-occurring diatoms, ciliates and pigmented (photosynthetic) dinoflagellates. The timing of several …

Effects of native forest and pastoral land use on the population dynamics and trophic role of the New Zealand freshwater crayfish Paranephrops planifrons (Parastacidae)
… the faster egg development and greater growth rates of juvenile P. planifrons in pasture sites, although food source may also have been a significant factor. Crayfish in pasture streams consumed more invertebrates than in native forest streams where leaf detritus dominated stomach contents. In …

The effects of sodium chloride ingestion on fluid balance and body fluid distribution during exercise
… of this thesis was to determine whether the ingestion of a concentrated sodium chloride solution (100mEq/1) during exercise would expand the plasma volume when fluid was ingested at approximately half the rate at which it was being lost as sweat. Six male cyclists exercised for 90 minutes in …
