Abstract This article describes a study of One Nation/One Project, a national post-pandemic arts-and-public-health initiative in the US. This values-based, convergent mixed-methods study found significant associations between arts participation, social cohesion, and well-being and offers a theory of change that illustrates these associations, as well as how arts participation increased social cohesion and enhanced well-being. At a moment when the severities of social divisions and loneliness are increasing in the US, this theory of change may enhance socia cohesion and well-being by encouraging cross-sector collaboration between the arts, public health, and municipal sectors and supporting investment in the arts.

Effluents from the textile industry, particularly those containing synthetic azo dyes, poses a significant environmental threat, necessitating the development of more effective and sustainable pollutant removal methods. Traditional dye removal techniques often fall short in efficiency and environmental impact, prompting the exploration of enzymatic degradation as a promising alternative. This study focuses on chloroperoxidase, a natural biocatalyst recognized for its ability to oxidize synthetic dyes into less harmful products. By exploring the mechanistic distinction between chlorination and oxidative processes, we investigate the enzyme’s specific degradation pathways for azo dyes and the resulting by-products. Utilizing analytical techniques, including liquid chromatography/mass spectrometry (LC/MS), and density functional theory (DFT), we gain insights into the decolorization mechanism, revealing that the enzyme preferentially generates oxidative products through C–N bond cleavage as its initial degradation step. These findings underscore not only the unique mechanistic properties of chloroperoxidase but also its potential as a biocatalyst for industrial applications. This study advocates further research into the optimization of enzyme-based systems, highlighting their relevance in advancing greener chemical practices in the textile industry, thus contributing to more sustainable manufacturing processes.

Novel trisubstituted ethylenes, , alkyl ring-substituted octyl phenylcyanoacrylates, RPhCH=C(CN)CO2CH2(CH2)6CH3 (where R is H, 2-methyl, 3-methyl, 4-methyl, 4-ethyl, 4-propyl, 4-i-propyl, 4-butyl, 4-t-butyl, 4-i-butyl) were prepared and copolymerized with styrene. The ethylenes were synthesized by the piperidine catalyzed Knoevenagel condensation of ring-substituted benzaldehydes and octyl cyanoacetate, and characterized by CHN analysis, IR, 1H and 13C NMR. All the ethylenes were copolymerized with styrene in solution with radical initiation (ABCN) at 70°C. The compositions of the copolymers were calculated from nitrogen analysis.

Novel oxy ring-trisubstituted isobutyl phenylcyanoacrylates, RPhCH=C(CN)CO2CH2CH(CH3)2 , where R is 2-ethyl, 4-(4-bromophenoxy), 2-(4-chlorophenoxy), 2-(4-fluorophenoxy), 4-(4-methoxyphenoxy), 3-(4-methylphenyl), 4-(4-methylphenyl), 4-acetoxy, 2,5-dimethyl were synthesized by the piperidine catalyzed Knoevenagel condensation of ring-substituted benzaldehydes and isobutyl cyanoacetate and characterized by CHN analysis, IR, 1H and 13C NMR. The acrylates were copolymerized with styrene in solution with radical initiation (ABCN) at 70°C. The compositions of the copolymers were calculated from nitrogen analysis.

The acrylates were copolymerized with styrene in solution with radical initiation (ABCN) at 70C. The compositions of the copolymers were calculated from nitrogen analysis.

The broadcast market currently faces changes which are very challenging for imaging solutions; the change from HD to UHD, and the introduction of HDR. In phases of change, more flexible solutions are needed. The Dynamic Pixel Management (DPM) technology already available in some FT-CCDs offered a unique solution for lossless switching between 4:3/16:9 aspect ratios, as well as between all the different HD formats, including 2.37:1 widescreen. Smaller UHD pixels do not offer the same performance as larger HD pixels and, until now, CMOS imagers have not allowed the pixel size to be changed. This is a real limitation for anyone who needs to produce in UHD as well as in HD. The new CMOS-based Xensium <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">HAWK</sup> imagers with DPM <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Ultra</sup> technology offer a solution to select the pixel size for native UHD or native HD, to deliver UHD or HD performance with no compromise. This paper explains the background and the development of the flexible pixel size through the DPM <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Ultra</sup> technology.
