Nanozymes for Environmental Pollutant Monitoring and Remediation

open access: yesSensors, 2021
Nanozymes are advanced nanomaterials which mimic natural enzymes by exhibiting enzyme-like properties. As nanozymes offer better structural stability over their respective natural enzymes, they are ideal candidates for real-time and/or remote ...

Measuring the development of social-emotional competence using behavioral rating scales in the context of school-based social and emotional learning

open access: yesSocial and Emotional Learning: Research, Practice, and Policy, 2023
Universal progress monitoring of student social-emotional competence (SEC) has increasingly been adopted as part of regular educational practices in the context of schoolwide social and emotional learning (SEL). However, an evidence base has not yet been

Linearly polarized field of a flat aperture

open access: yesФизика волновых процессов и радиотехнические системы, 2023
The article analyzes a flat circular aperture and proposes to use a new analytical expression that describes the radiation pattern of an elementary radiator of an antenna aperture depending on time and integration angle.

Shoaling Wave Shape Estimates from Field Observations and Derived Bedload Sediment Rates

open access: yesJournal of Marine Science and Engineering, 2022
The shoaling transformation from generally linear deep-water waves to asymmetric shallow-water waves modifies wave shapes and causes near-bed orbital velocities to become asymmetrical, contributing to net sediment transport.

Numerical Study on the Orthogonality of the Fields Radiated by an Aperture

open access: yesMathematics, 2023
This work studies the orthogonality of the fields radiated by the different modes of a radiating aperture. Waveguide modes exhibit an orthogonality property at the aperture cross-section that can be used to simplify calculations.

The Curvilinear Relationship between Age and Emotional Aperture : The Moderating Role of Agreeableness [PDF]

open access: yes, 2017
The capability to correctly recognize collective emotion expressions (i.e., emotional aperture) is crucial for effective social and work-related interactions. Yet, little remains known about the antecedents of this ability.

Clinical Implementation of Proton Therapy Using Pencil-Beam Scanning Delivery Combined With Static Apertures

open access: yesFrontiers in Oncology, 2021
Proton therapy makes use of the favorable depth-dose distribution with its characteristic Bragg peak to spare normal tissue distal of the target volume. A steep dose gradient would be desired in lateral dimensions, too.

Micro-morphological adaptations and tolerance assessment of selected vascular plant species exposed to vehicular exhausts

open access: yesEnvironmental Research Communications, 2023
The vehicular exhausts on roadsides negatively affect living organisms and disturb their environment. These negative impacts of vehicular exhausts on plants demand a scientific investigation of roadside plants in Abbottabad, Pakistan.
