The Effects of Using Different Adhesive on the Thickness Swelling Ratio of LVL Produced from Scotch Pine

open access: yesBioResources, 2022
Most wood properties are affected by changes in moisture content below the wood fiber saturation point. In this study, the thickness swelling ratios of laminated veneer lumber (LVL) produced from Scotch pine (Pinus sylvestris L.) bonded by using ...

Decarbonising Respiratory Care: The Impact of a Low‐Carbon Salbutamol Pressurised Metered‐Dose Inhalers

open access: yesAllergy, EarlyView.
Healthcare systems contribute up to 5% of global GHG emissions, with inhalers contributing a proportion of these. The carbon footprint of current salbutamol inhalers (pMDI with HFA‐134a propellant and DPI) and a planned salbutamol pMDI with low‐GWP propellant HFA‐152a was quantified across seven countries.

Bronchodilator responsiveness and onset of effect with budesonide/formoterol pMDI in COPD [PDF]

open access: yesRespiratory Medicine, 2011
Chronic obstructive pulmonary disease (COPD) patients are thought to have limited bronchodilator response, determined by changes in forced expiratory volume in 1s (FEV(1)). In this study, we assessed bronchodilator response in patients with COPD using not only FEV(1) but also changes in lung volume expressed as forced vital capacity (FVC) and ...

Recycling Polyurethane Materials: A Comparison of Polyol from Glycolysis with Micronized Polyurethane Powder in Particleboard Applications

open access: yesBioResources, 2014
Three different types of recycled polyurethane (PUR) material, two in powder form from a pulverizing process (one < 50 µm and one < 250 µm) and one in polyol form from a glycolysis process, were used as substitutes for polymeric methylene diphenyl ...

In Vitro Performance of Valved Holding Chambers in Paediatric Asthma Controller Therapy

open access: yesActa Paediatrica, EarlyView.
ABSTRACT Aim Research on the drug delivery of inhaled corticosteroids and combination medications via valved holding chambers (VHCs) with children's breathing patterns is limited. We aimed to evaluate the in vitro performance of commercially available VHCs without facemasks under preschooler breathing conditions, focusing on total delivered dose and ...

π‐Extended Chiral Molecular Triangular Prisms Exhibiting Boosted Circularly Polarized Luminescence Upon Self‐Assembly

open access: yesAggregate, Volume 7, Issue 6, June 2026.
A pair of π‐extended chiral triangular prisms based on pyromellitic diimide is synthesized from enantiopure macrocyclic precursors. They exhibit orange fluorescence and solvent‐dependent self‐assembly, enabling chiroptical inversion and amplification with |glum| values up to 1.15 × 10−2. Single‐crystal structures reveal solvent‐controlled conformations
