Exploring the multi-dimensionality of permanence and stability: Emotions, experiences and temporality in young people’s discourses about long-term foster care in Ireland

open access: yesQualitative Social Work, 2019
This paper focuses on qualitative findings on how young people in long-term foster care in Ireland interpret permanence and stability. We focus principally on subjective and relational permanence, emphasising the significance of these concepts for social

Ladder‐Type Benzene‐Perylene Dyes with Efficient Laser Properties in the Near‐IR by Detracting/Activating Low/High Frequency Vibronic Modes

open access: yesAdvanced Functional Materials, EarlyView.
The NNR‐n series of oligomeric nanographenes delivers exceptional emission performance. This work shows that this performance is originated by their ladder‐type structure, which effectively deactivates low‐frequency vibronic modes. This deactivation neglects the main pathway for non‐emissive deactivation, even in the near‐infrared region. The potential

The effect of time delay in plant--pathogen interactions with host demography

open access: yesMathematical Biosciences and Engineering, 2014
Botanical epidemic models are very important tools to study invasion, persistence and control of diseases. It is well known that limitations arise from considering constant infection rates.

Combinatorial Synthesis of Next Generation Water‐Soluble Quaternized N‐Halamine Oligomers with Long‐Lasting Antiviral Properties

open access: yesAdvanced Functional Materials, EarlyView.
A combinatorial library of dual‐functional antiviral oligomers incorporating N‐halamine and quaternary ammonium functionalities is developed for long‐lasting antiviral activity. The lead materials exhibit rapid and durable antiviral activity against SARS‐CoV‐2 variants and influenza H1N1, with 4 to 5 log reduction in viral copies at 5 mg mL−1 ...

An SEIR epidemic model with constant latency time and infectious period

open access: yesMathematical Biosciences and Engineering, 2011
We present a two delays SEIR epidemic model with a saturation incidencerate. One delay is the time taken by the infected individuals to becomeinfectious (i.e. capable to infect a susceptible individual), the seconddelay is the time taken by an infectious

Permanence and global stability of a May cooperative system with strong and weak cooperative partners

open access: yes, 2018
In this paper, a May cooperative system with strong and weak cooperative partners is proposed. First, by using differential inequality theory, we obtain the permanence and non-permanence of the system.

Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

open access: yesAdvanced Functional Materials, EarlyView.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Advanced Flame Retardant Strategies and Fire Performance Assessment for Safer Photovoltaics in Buildings: A Two‐Part Review

open access: yesAdvanced Functional Materials, EarlyView.
The integration of photovoltaic (PV) systems into building structures introduces distinct fire risks with critical implications for occupant safety. This review examines the key fire hazards associated with PV implementation and explores mitigation strategies, including flame‐retardant additives.

“Prejudice, in fact, is ignorance”: accessibility actions proposal for the inclusion and permanence of employees with disabilities at a federal university in the countryside of Rio Grande do Sul [PDF]

open access: yesAvaliação: Revista da Avaliação da Educação Superior
Law guarantees the entry of people with disabilities into the labor market. However, just making the vacancy possible does not guarantee the full inclusion and permanence of these people in the work environment.
