Finding predictive factors of exercise adherence in randomized controlled trials on low back pain: an individual data re-analysis using machine learning techniques.

Objective: To identify predictors of adherence in supervised and self-administered exercise interventions for individuals with low back pain.

Design: Cohort study.

Setting: Rehabilitation.

Valorization of corn stover in a single experimental unit: The synergistic effects of steam explosion and semi-continuous subcritical water processing.

Lignocellulosic waste, like corn stover (CS), is widely produced and serves as a key feedstock for biofuels and biochemicals. Semi-continuous subcritical water hydrolysis (SWH) is an eco-friendly method that breaks down cellulose and hemicellulose bonds. To boost fermentable sugar (FS) yields, steam explosion (SE) pretreatment was tested on CS, achieving a cellulose content of 74.

Aim of the study was to assess the use of pharmacological therapies provided in Nursing Homes and Protected Residences of the Umbria Region, with reference to central nervous system medications. In 2022, 200 ddd (defined daily doses) per 100 bed-days were administered in Umbria's long term care facilities, representing a 6.2% decrease compared to the previous year.

The involvement concept-replaceable or irreplaceable? A case for a conceptual analysis of a core concept of media psychological communication research.

The concept of involvement has enriched media psychological communication studies for more than three quarters of a century. The original concept of Sherif and colleagues-the so-called ego-involvement-has been extended piece by piece by various researchers over the decades, so that already in the 1980s voices were raised questioning the usefulness of such a broad meta-concept. In this article, we try to answer the question whether the involvement concept has become obsolete in the meantime by taking a more differentiated look at three different central understandings of the involvement concept (involvement as ego-involvement, as personal relevance and as mode of reception) and discussing their explanatory value.

Rapid 3D printing of unlayered, tough epoxy-alcohol resins with late gel points dual-color curing technology.

Additive manufacturing technologies and, in particular, vat photopolymerization promise complex structures that can be made in a fast and easy fashion for highly individualized products. While the technology has upheld this promise many times already, some polymers are still out of reach or at least problematic to print reliably. High-performance epoxide-based resins, which are regulated by chain transfer multifunctional alcohols, are a typical example of resins with late gel points, which require long irradiation times and high light intensities to print.
