Our goal is to develop computational approaches for studying groups of agents with natural mobility and social interactions. Such systems differ in many ways from engineered mobile systems because their agents can move on their own due to complex natural behaviors as well as under the control of the environment (for example drifting to follow wind patterns). We wish to model such systems using ...

Population densities of Belonolaimus longicaudatus, Pratylenchus brachyurus, and Trichodorus christiei were determined from soil samples taken weekly in Tifton, Georgia during a 14-month period (except for April and May) at 15-cm increments to a depth of 105 cm. Belonolaimus longicaudatus predominately inhabited the top 30 cm of soil that was 87-88% sand, 6-7% silt, and 5-7% clay. No specimens ...

Ocean Drilling Program (ODP) Leg 156 examined hydrological, geochemical, structural, and sedimentological processes at the toe of the northern Barbados accretionary prism (Shipley, Ogawa, Blum, et al., 1995). As part of this program, more than 400 samples were collected from Sites 948 and 949 for grain-size analysis. The primary objective of these analyses was to accurately determine weight per...

Abstract Hydrometer method is the standard that normally used to determine fine particle size distributions for soil classification purposes. This study aims develop new enable quick determination of silt-clay distribution compared hydrometer requires procedure pretreatment and additional 24 hours required complete test. The various samples were collected from seven different locations includin...

This study reports results of sediment bioslurry treatment and earthworm bioaccumulation for polycyclic aromatic hydrocarbon (PAH) contaminants found in sediment dredged from Milwaukee Harbor. A significant finding was that bioslurry treatment reduced PAHs on the sediment clay/silt fraction but not on the sediment coal-derived fraction and that PAH reduction in the clay/silt fraction correlated...

An outbreak of tsetse-transmitted trypanosomiasis resulted in more than 50% losses of domestic pigs in the Eastern Region of Ghana (source: Veterinary Services, Accra; April 2007). In a control trial from May 4(th)-October 10(th) 2007, the efficacy of insecticide-treated mosquito fences to control tsetse was assessed. Two villages were selected--one serving as control with 14 pigsties and one e...

Plant immunity is modulated by several abiotic factors, and microbiome has emerged as a major biotic driver of plant resistance. Recently, few studies showed that plants also modify resistance to pests pathogens in their neighborhood. Several types neighborhood could be identified depending on the biological processes at play: intraspecific interspecific competition, kin stranger recognition, p...

We propose an extension to the HTTP protocol that allows specification of domain borders in the form of fences – a service provider is empowered with the ability to specify what exactly they would like to accept as being within their domain. The extension also provides a second asset which is a policy specification or data visa; these visas specify what types of data can be brought into the fen...
