Assessment of Initial Stay Time and Work‐Rest Scheduling Over Consecutive Moderate‐Intensity Workdays in Hot Environments in Young and Older Males and Females

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Initial stay time (IST), the duration of continuous work before core temperature reaches 38.0°C, has been characterized in young and older adults but not across consecutive work periods or in conjunction with standard work‐rest cycles.

A Dithio Vinylthio C2 Synthon Enabling Crystalline and Luminescent Sulfur‐Decorated Polymers

open access: yesAngewandte Chemie International Edition, EarlyView.
Transforming CaC2 into a modular C2 building block enables the synthesis of α,ω‐bis(vinylthio) monomer and its conversion into crystalline, sequence‐defined sulfur‐decorated polymers. Their dense thioether clustering induces nonconventional luminescence and provides structure–function control in a more‐sustainable polymer platform.

Electronic Resonance Network Stabilized Crystal Structure in High‐Nickel Cathodes for Lithium‐Ion Batteries

open access: yesCarbon Energy, EarlyView.
Transition metal (TM) ions with empty eg orbitals induce single‐electron delocalization in Ni3+ to form the resonance structure of Ni─OO─TM through the high‐entropy effect. High‐nickel cathode materials with electron resonance structure have the advantages of improving thermodynamic stability, suppressing phase transitions, and mitigating lattice ...

INFLUENCE OF ARTIFICIAL LUNG VENTILATION ON REAL ENERGY EXPENDITURE VALUE OF SURGICAL INTENSIVE CARE UNIT PATIENTS

open access: yesКреативная хирургия и онкология, 2017
Elective or emergence surgery often is closely connected with development of hypercatabolism-hypermetabolism syndrome. Non-effective and late nutritional support in surgical critically ill patients lead to several consequences and complications such as ...

Pyrrolic‐Nitrogen‐Enriched Aerogels With Magnetic Responsiveness Enable Cooperative Hydrogen‐Bond Regulation for High‐Performance Solar Interfacial Evaporation

open access: yesCarbon Energy, EarlyView.
A pyrrolic‐nitrogen‐enriched ferromagnetic aerogel enables sophisticated cooperative regulation of hydrogen bonding, whereby this dual‐regulatory mechanism effectively reduces vaporization enthalpy while simultaneously enhancing molecular dynamics. The system demonstrates exceptional self‐cleaning capability and exhibits superior performance in the ...

Inverse Compton Contribution to the Star-Forming Extragalactic Gamma-Ray Background

open access: yes, 2012
Fermi has resolved several star-forming galaxies, but the vast majority of the star-forming universe is unresolved and thus contributes to the extragalactic gamma ray background (EGB). Here, we calculate the contribution from star-forming galaxies to the

Unravelling the initiator‐only stage in alginate grafting: Radical‐induced depolymerization and its impact on acrylamide grafting efficiency

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Free‐radical grafting of natural polymers often assumes that initiators only create active sites before monomer addition. We tested this by exposing sodium alginate to potassium persulphate (KPS) under typical grafting conditions without monomer (acrylamide).

Indirect calorimetry to estimate energy requirements for growing and finishing Nellore bulls

open access: yesJournal of Integrative Agriculture, 2017
Determination of nutritional requirements is the basis for diet formulation. The objectives of this study were to determine the net energy requirements for maintenance (NEm) and weight gain (NEg) in Nellore bulls during the growing and finishing phases ...

Co‐Firing Slow Solidification Process for Growing Indium‐Doped Cs3Cu2I5 Single Crystals With Record‐Breaking X‐Ray Detection Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel brand‐new co‐firing slow solidification process has been used to prepare Cs3Cu2I5: In single crystals (SCs), which demonstrate record‐breaking X‐ray detection performance. The regular‐shaped Cs3Cu2I5: In wafer obtains a high light yield (74 368 Ph MeV−1), which is the highest related to indium‐doped Cu‐based perovskites.
