Aquatic Effects of a Localized Oil Spill on Lake Conway, AR and Its Tributaries [PDF]

open access: yes, 2015
Oil spills, no matter where they occur, elicit environmental concern and avoiding these disasters should be a priority. Old pipelines that are not regularly maintained and carry large amounts of crude oil long distances are of particular concern.

The Molecular Mechanism of Calcification in Aquatic Organisms [PDF]

open access: yesBioscience, Biotechnology, and Biochemistry, 2013
Biomineralization is a process of mineral deposition by organisms. Calcium salts are the major component of various biominerals, calcium carbonate being the predominant type in aquatic organisms. The mechanism of biomineralization has been conventionally analyzed by microscopic observation.

A Chirality‐Converted Bacteriolytic Dodecapeptide Regulates Vibrio‐Induced Polymicrobial Infection and Ameliorates Invasion‐Associated Gut Microbiota Disequilibrium

open access: yesAdvanced Science, EarlyView.
Multidrug‐resistant Vibrio infections are rising rapidly and threaten coastal populations worldwide. This study introduces D‐zp37, a chirality‐engineered antimicrobial peptide with exceptional potency against resistant Vibrio species. D‐zp37 kills planktonic cells, blocks mixed‐species biofilms, disrupts essential bacterial stress responses, and shows ...

Determination of Silver Binding to Natural Organic Matter Using Ion Selective Electrode [PDF]

open access: yes, 2017
Natural organic matter (NOM) is considered an important factor in the protection of the aquatic environments; organic ligands can complex with metals, to decrease their toxicity and bioavailability. NOM is measured as dissolved organic carbon (DOC) in mg

Physiological Effects of Five Different Marine Natural Organic Matters (NOMs) and Three Different Metals (Cu, Pb, Zn) on Early Life Stages of the Blue Mussel (Mytilus galloprovincialis) [PDF]

open access: yes, 2017
Metals are present in aquatic environments as a result of natural and anthropogenic inputs, and may induce toxicity to organisms. One of the main factors that influence this toxicity in fresh water is natural organic matter (NOM) but all NOMs are not the

Vacuum–Laser Fabrication of Programmable Soft Actuators

open access: yesAdvanced Science, EarlyView.
A rapid and accessible fabrication strategy for inflatable soft actuators is presented, combining vacuum sealing with laser cutting of low‐cost thermoplastic pouches. The method enables precise sealing, fast fabrication, and programmable multi‐cell geometries.

Effects of light intensity and photoperiod on ovarian development of Procambarus clarkii (Girard, 1852): Comparative proteomics analysis, growth performance and biochemical

open access: yesAquaculture Reports
Physiological and biochemical analysis showed that the decrease in photoperiod could inhibit the growth and ovarian development of Procambarus clarkii, while the decrease in light intensity could promote the growth of P.

Aquatic biosurvey of the Lovell River on UNH land [PDF]

open access: yes, 2003
We assessed the physical, chemical and biological conditions at two sites along the Lovell River on University of New Hampshire (UNH) -owned conservation land. The discharge was 4.4 m3 s-1 at Site 1 and 5.7 m3 s -1 downstream at Site 2.

Policies and regulations in Mexico with regard to genetic technology and food security [PDF]

open access: yes, 2016
In 1988 the first application for field trials of a GMO was formally received in Mexico. Since then a Biosafety law, few bylaws and national official standards were enacted in order to regulate the safe use of GMOs and to evaluate, control and avoid ...
