A technique for laboratory estimation of net trophic transfer efficiency of polychlorinated biphenyl (PCB) congeners to piscivorous fish from their prey is presented. To maximize applicability of the laboratory results to the field, the piscivorous fish should be fed prey fish that are typically eaten in the field.

Microbial eukaryotes are both a source of photosynthetically-derived carbon and top predatory species in permanently ice-covered Antarctic lakes. This report describes an enrichment culture approach to isolate metabolically versatile microbial eukaryotes from the Antarctic lake, Lake Bonney, and assesses inorganic carbon fixation potential using a radioisotope assay for Ribulose-1,5-bisphophate carboxylase oxygenase (RubisCO) activity.

Source: Jose Roberto Moreto, Gustaaf Jacobs and Xiaofeng Liu, Department of Aerospace Engineering, San Diego State University, San Diego, California The delta wing, shown in Figure 1D, is a popular design in high-speed airplanes due to its superb performance in transonic and supersonic flight regimes. This type of wing has a small aspect ratio and high sweep angle, which reduces drag at high subsonic, transonic and supersonic flight regimes. The aspect ratio is defined as the wing span divided...
FAQs
Seasonal and short-term water-level changes can shift the observed shoreline position, so a measurement may describe conditions at one time rather than a permanent boundary. Engineers should record the water level and relevant site conditions alongside the shoreline location. Those records make repeat surveys more comparable and help distinguish actual shoreline movement from temporary variation.
Shoreline position alone does not capture how land and water meet at a site. Bank geometry describes the form of the edge, while local conditions add context for interpreting the measurement. Together, these observations support engineering judgments about erosion, infrastructure placement, and flood-related exposure, rather than treating every shoreline point as physically equivalent.
Each is identified as a way to establish the lake boundary, but the surrounding documentation remains important regardless of the method. Engineers should connect the located edge with water level, bank geometry, and local site conditions. This preserves the context needed to compare observations over time and apply them to design or shoreline management.
A useful record should pair the shoreline position with water level, bank geometry, and local site conditions. Engineers may establish the position through a field survey, GPS, level measurements, or remote sensing, then preserve the associated conditions for later comparison. This combination creates a more interpretable dataset for design and shoreline management than location data alone.
It supports reservoir planning, flood-risk evaluation, erosion monitoring, habitat protection, and infrastructure placement. In each case, the measurement supplies a documented relationship between the lake and adjacent land. Repeated observations are especially valuable where the shoreline changes, because engineers can compare positions and conditions over time when assessing risks or planning work near the edge.
Consistent methods and recorded water conditions allow measurements from different dates to be compared more reliably. Engineers can use those comparisons to identify patterns in shoreline movement and account for changing conditions during design or assessment. The result is a stronger basis for flood-risk evaluation, erosion monitoring, and placing infrastructure where shoreline shifts matter.
