Identifying the environmental conditions that determine the distribution of an endangered estuarine fish to manage risk of entrainment

open access: yesFrontiers in Ecology and Evolution
Allocation of scarce water resources to meet beneficial but competing end uses has become commonplace in drought-stricken western North America. In the Sacramento-San Joaquin Delta in California, regulatory agencies endeavor to protect the endemic and ...

Evaluation of a large-scale flow manipulation to the upper San Francisco Estuary: Response of habitat conditions for an endangered native fish

open access: yesPLoS ONE, 2020
While flow is known to be a major driver of estuarine ecosystems, targeted flow manipulations are rare because tidal systems are extremely variable in space and time, and because the necessary infrastructure is rarely available.

Batch-sequential design and heteroskedastic surrogate modeling for delta smelt conservation

open access: yesThe Annals of Applied Statistics, 2022
Delta smelt is an endangered fish species in the San Francisco estuary that have shown an overall population decline over the past 30 years. Researchers have developed a stochastic, agent-based simulator to virtualize the system, with the goal of understanding the relative contribution of natural and anthropogenic factors suggested as playing a role in

Investigation of Molecular Pathogen Screening Assays for Use in Delta Smelt

open access: yesSan Francisco Estuary and Watershed Science, 2022
Pathogen surveillance must be part of any population supplementation or reintroduction program for the conservation of threatened and endangered species. The unintended transmission of pathogens can have devastating effects on these already at-risk populations or the natural ecosystem at large.

Comparative Analysis of Metal Preloading Technologies in Batteries and Capacitors

open access: yesEcoEnergy, EarlyView.
Metal preloading strategies play an important role in efficient batteries and hybrid capacitors to compensate for the consumed metals at the first discharge. This article reviews recent progress in preloading technologies in lithium‐ion and other metal‐ion systems.

Lipid correction of hydrogen stable isotope ratios in fish

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Lipids are known to affect stable isotope ratio of organisms, especially δ13C values, and simple arithmetic lipid‐correction procedures have been developed based on the carbon to nitrogen ratio (C : N) that is a proxy for lipid content. Equivalent issues will likely arise with the increasing use of hydrogen isotopes in ecology, but as yet no ...

Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

open access: yessteel research international, EarlyView.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Evaluating the impact of captive ancestry on the growth and survival of Delta Smelt in a captive environment

open access: yesAquaculture Reports
Delta Smelt Hypomesus transpacificus, is an endangered fish endemic to the California San Francisco Bay-Delta, USA. Extreme declines of the wild Delta Smelt population have prompted use of cultured fish to supplement the wild population since 2021 to ...

Modification of the biological intercept model to account for ontogenetic effects in laboratory-reared delta smelt (Hypomesus transpacificus)* [PDF]

open access: yes, 2007
We investigated age, growth, and ontogenetic effects on the proportionality of otolith size to fish size in laboratory-reared delta smelt (Hypomesus transpacificus) from the San Francisco Bay estuary.

Effect of Intrinsic Carbon in Hot Briquetted Iron on Melting and Refining Efficiency under Electric Arc Furnace Conditions for Sustainable Steelmaking with Active Use of H2‐Reduced Iron

open access: yessteel research international, EarlyView.
The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...
