Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Production of the chironomids of the Uchinsk Reservoir. [Translation of: Methods for the estimation of production of aquatic animals. (Handbook and papers) (ed. G. G. Vinberg) p226-239. Minsk, Vysheishaya Shkola, 1968] [PDF]

, 1968
The method of E.V. Borutski was used for determining the production of chironomids, that is, the dynamics of the number and biomass of the larvae were analysed, their death, a calculation of emergence and the number of deposited egg layings was carried ...

A mesocosm experiment investigating the effects of substratum quality and wave exposure on the survival of fish eggs [PDF]

, 2010
In a mesocosm experiment, the attachment of bream (Abramis brama) eggs to spawning substrata with and without periphytic biofilm coverage and their subsequent survival with and without low-intensity wave exposure were investigated.

The impacts of coastal protection structures in California’s Monterey Bay National Marine Sanctuary [PDF]

, 2005
This report outlines the potential impacts of coastal protection structures on the resources of the Monterey Bay National Marine Sanctuary. At least 15 miles of the Sanctuary’s 300-mile shoreline are currently armored with seawalls and riprap revetments.

Complex Interactions of Fish, Snails, and Littoral Zone Periphyton [PDF]

Ecology, 1998
This study examines the interaction of predation and resource-based effects of fish on freshwater periphyton communities. Current theory predicts that fish primarily influence periphyton communities by controlling herbivore densities. But fish may also influence algal communities by increasing available nutrients via nutrient recycling.

A model for the Guaraní expansion in the La Plata Basin and littoral zone of southern Brazil

, 2015
Since the 19th century, it has been proposed that the wide geographic distribution of the Guarani indigenous populations in large areas of South America was the result of prehistoric movements of large numbers of people through the main rivers of the La ...

Parallel Electrical Integration of Photo Bio Electrochemical Systems (photo‐BESs): Performance Gains and Load Dependency

Advanced Materials Technologies, EarlyView.
Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.

Rotifers of the upper Paraná River floodplain: additions to the checklist

Brazilian Journal of Biology
Rotifers present a high diversity in freshwater ecosystems. This study registered 11 genera and 42 species, new records for the Upper Paraná River floodplain. These results showed an increase in rotifer diversity in this ecosystem from 184 to 230 species.

Using coarse-scale physical lake characteristics to model lake sturgeon (acipenser fulvescens) feeding habitat and their prey [PDF]

, 2012
Coarse-scale, physical lake characteristics (lake fetch, shoreline exposure, and littoral-zone slope) were investigated as to their ability to predict benthic macroinvertebrate communities and lake sturgeon feeding along shorelines in the southern ...
