PIP Water Transport and Its pH Dependence Are Regulated by Tetramer Stoichiometry
(Cell Press, 2016-03)
Many plasma membrane channels form oligomeric assemblies, and heterooligomerization has been described as a distinctive feature of some protein families. In the particular case of plant plasma membrane aquaporins (PIPs), ...
Forest Structure Affects the Stoichiometry of Periphyton Primary Producers in Mountain Streams of Northern Patagonia
(Springer, 2016-11-02)
Riparian zones are major components of stream ecosystems that influence the physical, chemical, and biological parameters. In particular, the distribution of vertical foliage and the structure of riparian vegetation determine ...
Crop residues used as food drive enzyme activation and enzymatic stoichiometry in casts of the earthworm Aporrectodea caliginosa (Savigny, 1826)
(Elsevier Science, 2021-10)
Earthworms are drivers of soil processes as soil structure formation and organic mattercycling. Through providing soil microbiota with mucus, temperature, and organicresources within their guts, earthworms enhance their ...
Biodegradation of bisphenol A and its metabolic intermediates by activated sludge: Stoichiometry and kinetics analysis
(Elsevier, 2016-01)
Bisphenol A (BPA) has been described as a estrogenic compound. However, it is used in the production of polycarbonate, epoxy resins and other plastics. Mixed microbial cultures, such as activated sludge, have been proposed ...
Light intensity regulates stoichiometry of benthic grazers through changes in the quality of stream periphyton
(University of Chicago Press, 2019-06)
In mountain streams, light is a key factor for primary production and primary producer nutrient stoichiometry, or the relative composition of carbon (C) compared to phosphorous (P) and nitrogen (N) in primary producers. ...
Glyphosate photodegradation: Stoichiometry, kinetic and catalytic effects
(Inderscience Enterprises, 2019-10)
Photodegradation of glyphosate (PMG) in aqueous solution by the action of UV-light and the catalytic effect of copper and copper-alga Ulva lactuca is described. The photodegradation kinetic reaction of PMG can be explained ...
Effects of oxygen non-stoichiometry on the physical properties of the YBaCo2 O5 + δ layered cobaltites
(Elsevier Science, 2006-10)
We have synthesized the layered cobaltites YBaCo2 O5 + δ with different oxygen contents (δ1 and δ2), and characterized its structural and physical properties using various experimental techniques within the 80-500 K ...
Exsolution and electrochemistry in perovskite solid oxide fuel cell anodes: Role of stoichiometry in Sr(Ti,Fe,Ni)O3
(Elsevier Science, 2019-11-01)
The exsolution of metal cations from oxides under reducing fuel conditions results in the formation of surface metallic nanoparticles, which can reduce Solid Oxide Fuel Cell anode polarization resistance. However, the loss ...
