A Mathematical Tightening of Instantaneous Indoor and Outdoor Dry-Bulb and Wet-Bulb Temperature Tolerances

open access: yesEnergies, 2020
To reduce the inaccuracy in energy efficiency evaluation, indoor and outdoor dry-bulb and wet-bulb temperature (D&WBT) tolerances in the currently enacted Chinese room air conditioner (RAC) national standard were tightened into narrower intervals in ...

Formation and Application of High Reflectivity Controllable Barium Sulfate Microspheres

open access: yesCrystals, 2018
This paper investigated the influence of reaction conditions on particle morphology. X-ray powder diffraction (XRD), particle size distribution (PSD), and scanning electron microscopy (SEM) were used to characterize the morphology of barium sulfate.

Grouping Methods of Cluster Dynamics Model for Precipitation Kinetics

open access: yesMetals, 2020
Due to its simplicity and efficiency, cluster dynamics modeling has been widely used to simulate microstructure evolution in materials, such as defect formation in metals. However, its computation cost becomes prohibitive when the clusters grow too large,

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

Emissions of Arsenic in Sweden and Their Reduction

open access: yesEnvironmental Health Perspectives, 1977
The role of arsenic in Sweden is generally described, including raw materials, exports/imports, products, consumption, etc. An attempt was also made to estimate the transport of arsenic in Sweden. The quantities of arsenic in raw materials, the emissions of arsenic from such processes as copper smelters and chemical industries, and the amounts of ...

Is carbon removal delaying emission reductions?

open access: yesWIREs Climate Change, 2023
AbstractCarbon dioxide removal is rapidly becoming a key focus in climate research and politics. This is raising concerns of “moral hazard” or “mitigation deterrence,” that is, the risk that promises of and/or efforts to pursue carbon removal end up reducing or delaying near‐term mitigation efforts.
