Protecting Blueberries from Freezes in Florida

open access: yesEDIS, 2023
Blueberries bloom in late winter or early spring in Florida, making the flowers and young fruit highly susceptible to freeze and frost injury. Killing freezes can occur as late as mid to late March throughout much of Florida, long after the initiation ...

Trauma-related dissociation and the autonomic nervous system: a systematic literature review of psychophysiological correlates of dissociative experiencing in PTSD patients

open access: yesEuropean Journal of Psychotraumatology, 2022
Background: Neurophysiological models link dissociation (e.g. feeling detached during or after a traumatic event) to hypoarousal. It is currently assumed that the initial passive reaction to a threat may coincide with a blunted autonomic response, which ...

Psychophysiological reactions during the trauma-film paradigm and their predictive value for intrusions

open access: yesEuropean Journal of Psychotraumatology, 2023
Background: Adequate adaptation of the autonomic nervous system (ANS) is crucial in potentially life-threatening situations. The defence cascade provides a descriptive model of progressing dominant physiological reactions in such situations, including ...

Self-healing in cementitious composite containing bacteria and protective polymers at various temperatures

open access: yesMagazine of Civil Engineering, 2021
Autonomous sealing of cracks in concrete through bacteria-induced calcification has become a topic of great concern in the last two decades. This paper is focused on two main issues of the so-called bio-based self-healing concrete, i.e. protection of the
