Response of deep-water agglutinated foraminifera to dysoxic conditions in the California Borderland basins [PDF]

open access: yes, 1995
Analysis of agglutinated benthic foraminifera from surface samples collected in the San Pedro and Santa Catalina Basins reveals a predictable relationship between the proportions of morphogroups with decreasing bottom water oxygen levels and with the ...

Advancing design strategies in smart stimulus‐responsive liposomes for drug release and nanomedicine

open access: yesBMEMat, EarlyView.
Schematic illustration of stimulus‐responsive liposomes designed for controlled drug release and nanomedicine. The innermost circle represents different liposomal structures, including unilamellar, multilamellar, and multivesicular liposomes. The middle layer illustrates the responsive phospholipid components.

Neuroprotective effects of some creatine derivative compounds

open access: yesJournal of Biological Research, 2010
Some derivatives more lipophylic than creatine, thus theoretically being capable to better cross the blood-brain barrier, were studied for their neuroprotective effect in mouse hippocampal slices.

Close mixed-planting with paddy rice reduced the flooding stress for upland soybean

open access: yesPlant Production Science, 2022
Close mixed-planting is a new concept of mixed cropping that allows greater complementary effects under various stress conditions; in this system, oxygen and/or water transfer occurs through the tightly entangled root system of the two species.

Actively decaying or just poorly preserved? Can we tell when plant and invertebrate remains in urban archaeological deposits decayed? [PDF]

open access: yes, 2004
We have recendy argued that poorly preserved delicate macrofossil remains of plants and invertebrates in near-surface deposits in York are in active decay, rather than being preserved in stasis, part-way down the decay trajectory.

Low-dose alum application trialled as a management tool for internal nutrient loads in Lake Okaro, New Zealand [PDF]

open access: yes, 2008
Aluminium sulfate (alum) was applied to Lake Okaro, a eutrophic New Zealand lake with recurrent cyanobacterial blooms, to evaluate its suitability for reducing trophic status and bloom frequency.

Tailoring Se‐Mediated Co‐Co Dual‐Atom Sites for Oxygen and Iodide Electrocatalysis Toward High‐Efficiency and Ultradurable Zinc‐Air/Iodide Hybrid Batteries

open access: yesCarbon Energy, EarlyView.
A Se‐mediated Co dual‐atom catalyst replaces sluggish oxygen evolution with efficient iodide oxidation in zinc‐air/iodide hybrid batteries. Se‐induced d‐p orbital hybridization optimizes adsorption, enabling a low 0.365 V voltage gap and superior durability, fundamentally overcoming conventional kinetic bottlenecks.

Evidence of late Quaternary environmental change in a continental east Antarctic lake from lacustrine sedimentary pigment distributions [PDF]

open access: yes, 2005
A sediment core from Progress Lake, one of the oldest lacustrine sequences in East Antarctica, contains distinct zones dating from a previous interglacial (most likely Marine Isotope Stage 5e, c.

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

Spontaneous running wheel exercise during pregnancy prevents later neonatal-anoxia-induced somatic and neurodevelopmental alterations

open access: yesIBRO Neuroscience Reports
Introduction: About 15–20 % of babies that suffer perinatal asphyxia die and around 25 % of the survivors exhibit permanent neural outcomes. Minimization of this global health problem has been warranted.
