Titration of nicotine intake in smokers switching to reduced nicotine content cigarettes with access to alternative nicotine systems: Secondary analysis of a randomized clinical trial

open access: yesAddiction, Volume 121, Issue 7, Page 1899-1906, July 2026.
Abstract Background and aims Mandated reduction of the nicotine content of cigarettes to reduce addictiveness to minimal levels has the potential to substantially reduce combusted cigarette use and promote public health. This paper examined the hypothesis that when people who smoke cigarettes are switched to very low nicotine content (VLNC) cigarettes ...

Incorporating County‐Level Spatial Resolution in Maize Life Cycle Emissions Analysis in Illinois, USA

open access: yesGCB Bioenergy, Volume 18, Issue 7, July 2026.
Spatial life cycle analysis (LCA) shows that the carbon intensity (CI) of maize grain used for ethanol production in Illinois, USA varies across the state, with an average carbon intensity of 14%–17% lower than the national average used in policy decisions.

Energy‐Efficient Combustion Technologies and Burner Designs for Glass Melting Furnaces

open access: yesInternational Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Glass production is one of the most energy‑intensive manufacturing processes, requiring furnace temperatures above 1600°C. These temperatures depend on burners that must balance thermal efficiency with emission reductions. This article reviews the development of combustion systems in glass furnaces, focusing on their impact on energy ...

From Post‐Fire Interventions to Community Resilience: Learning and Adaptation in a Cross‐Border Region

open access: yesSociologia Ruralis, Volume 66, Issue 3, July 2026.
ABSTRACT This paper explores the concept of community resilience in the context of cross‐border wildfire management in the Bohemian and Saxon Switzerland National Parks. It focuses on three interrelated dimensions: institutional preparedness, inclusive community engagement and adaptive learning in the aftermath of natural disasters.

Flow and combustion in disc and pent-roof SI engines [PDF]

open access: yes, 2006
Reported in this thesis is a study of combustion in a disc-shaped combustion chamber spark ignition engine, and in-cylinder flow and combustion in an idealised pent-roof spark ignition engine. Both engines were skip fired, to remove residuals and ensure

The Importance of Tire Wear Particles for Atmospheric Ice Nucleation

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Tire wear particles (TWPs) are prevalent microplastic particles in the atmosphere and pose significant environmental and health risks to humans. Here, we investigated the ice nucleation activity (INA) of TWPs under mixed‐phase cloud conditions (∼−20.0°C < T < −5.0°C) and its changes caused by different environmental exposures, including UV and

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

open access: yesAdvanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.
