The influence of data characteristics on detecting wetland/stream surface-water connections in the Delmarva Peninsula, Maryland and Delaware.

The dependence of downstream waters on upstream ecosystems necessitates an improved understanding of watershed-scale hydrological interactions including connections between wetlands and streams. An evaluation of such connections is challenging when, (1) accurate and complete datasets of wetland and stream locations are often not available and (2) natural variability in surface-water extent influences the frequency and duration of wetland/stream connectivity. The Upper Choptank River watershed on the Delmarva Peninsula in eastern Maryland and Delaware is dominated by a high density of small, forested wetlands.

Velocity constancy in a virtual reality environment.

During everyday life the brain is continuously integrating multiple perceptual cues in order to allow us to make decisions and to guide our actions. In this study we have used a simulated (virtual reality--VR) visual environment to investigate how cues to speed judgments are integrated. There are two sources that could be used to provide signals for velocity constancy: temporal-frequency or distance cues.

[Rhinitis therapy. Experiences with triprolidine hydrochloride/pseudoephedrin hydrochloride, a decongestive and antiallergic therapeutic agent].

63 patients were treated with the combination of pseudoephedrine hydrochloride and triprolidine hydrochloride (Actifed). Indications were infectious, allergic and vasomotoric rhinitis. The 63 patients divided in 32 children in the age of 2 to 12 years and 31 adults in the age of 14 to 56 years.

Characteristics of mastadenovirus h 8, the causative agent of epidemic keratoconjunctivitis.

Adenovirus 8 (Ad 8, strain 1127) has the general structural features of an adenovirus; it produces the genus-specific hexon antigen. The fiber length of 12 nm corresponds to that of other subgenus D adenoviruses. In hemagglutination-inhibition, Ad 8 is related to Ad9 and Ad 15/H9.
