A pilot scale plant at Technology Readiness Level (TRL) 6 comprising an electrochemical ex-cell continuous production of sodium peroxodicarbonate and a thermal depolymerization plug flow reactor for kraft lignin conversion is established. Due to the labile nature of the "green" oxidizer peroxodicarbonate, special attention must be paid to the production parameters in order to optimize its use. A simplified design model describing steady-state and transient operations is formulated and finally validated against experimental data from the electrolysis setup. Design trade-offs are visualized, and their impact on specific energy consumption is evaluated. The pilot plant was operated for a 20-month period for more than 1200 h on-stream. Optimized process conditions result in vanillin yields of 8 wt % and thus prove the successful scale-up.

Purpose: The primary challenge in infant care is developing a comprehensive, rapid, and reliable assessment tool that is minimally dependent on subjective evaluations and applicable in various inpatient settings. This study aims to develop and assess the structural validity of the Infant Nursing Assessment Scale (INA), enabling a comprehensive evaluation of hospitalized newborns and infants.
Design And Methods: A development and validation study based on cross-sectional design was undertaken.

Objective: To review and synthesize existing evidence on the effect of mirror therapy (MT) on motor and functional recovery and the effect of unimanual and bimanual MT in individuals with subacute stroke.
Methodology: PubMed, Physiotherapy Evidence Database, Cochrane, and Airiti Library were searched for relevant studies. Randomized and pilot randomized controlled trials comparing MT with sham MT or conventional therapy were included.

Objectives: Ataxia is a common symptom in patients with Cerebellar subtype of Multiple system atrophy (MSA-C), but effective treatments remain elusive. The present study aims to investigate whether repetitive transcranial magnetic stimulation (rTMS) over the bilateral cerebellum could relieve ataxia in patients with MSA-C.
Patients And Methods: This is a single-center, randomized and double-blind trial.
Introduction: Fighter pilots are a population particularly vulnerable to developing mental fatigue, which puts the safety of military operations at risk. Although there is no gold standard tool for its assessment, Yoshitake's Feeling of Fatigue Scale (FFS) appears promising for application to fighter pilots as it has already been validated for Brazilian commercial airline pilots. The objective of this study was to evaluate the psychometric properties of the FFS in Brazilian fighter pilots.

Introduction: Many questions are still being asked about the actual health effects of exposure to a fume event for airline crewmembers. To shed new light on this controversy about so-called aerotoxic syndrome, we undertook a large-scale epidemiological study.
Methods: We present a retrospective cohort study involving 14,953 crewmembers, including 2577 exposed to a fume event and 12,376 matched controls to estimate the hazard ratio of a subsequent sickness.
