Differences in early developmental rate and yolk conversion efficiency in offspring of trout with alternative life histories [PDF]

, 2016
Partial migration, in which some individuals of a population migrate while other individuals remain resident, is generally associated with ontogenetic shifts to better feeding areas or as a response to environmental instability, but its underlying ...

Electrochemical Nitrate Reduction Reaction to Ammonia at Industrial‐Level Current Densities

Advanced Science, EarlyView.
This review starts from the mechanism and theoretical basis of electrochemical nitrate reduction reaction (NO3−RR), and systematically summarizes and discusses the design strategies of industrial‐level current density catalysts. In addition, the progress of industrial‐level NO3−RR‐based electrolyzers, including flow reactor and membrane electrode ...

The Economic Well-Being of Farmers As An On-going National Public Policy Issue [PDF]

Aggregate farm income is the standard measure of farm household economic well-being. In Canada farm groups have used a multi-year decline in one measure of farm income - realized net income, to press for increased financial transfers.

A Yolk@Shell Photothermal Structure for Integrated Solar‐Driven Undrinkable Water Purification and Thermoelectric Power Generation

Advanced Science, EarlyView.
A yolk@shell structured photothermal evaporator was prepared via simple sol‐gel and spray coating methods. By taking advantage of the unique yolk@shell structure, the position of the TE module within the evaporator can be optimized without affects its water evaporation performance. This results in efficient and stable evaporation (3.08‐3.17 kg m−2 h−1)‐

Study on the growth and reproduction of Hypophthalmichthys Molitrix in the low reaches of the Yellow River

All Life
This study elucidated the growth and reproductive characteristics of Hypophthalmichthys molitrix in the lower Yellow River. A relationship equation between length (L) and weight (W) was established as W = 2.0 × 10−5 × L3.0037, with maximum limit body ...

Self‐Healing Liquid Metal‐Elastomer Circuits for Robust Underwater Electronics

Advanced Electronic Materials, EarlyView.
Soft electronics for underwater environments require materials that maintain function under mechanical strain and environmental exposure. This work shows that liquid metal‐elastomer composites preserve, or even improve, their electromechanical and self‐healing performance after aging in ambient, freshwater, and saltwater, highlighting their promise for

Toxicokinetics and bioconcentration of polycyclic aromatic hydrocarbons in freshwater isopods [PDF]

, 1999
A novel method based on a first-order two-compartment model was used to determine the bioconcentration and toxicokinetic rate constants of six different polycyclic aromatic hydrocarbons (PAHs) in the freshwater isopod Asellus aquaticus, a common species ...
