Ultimately, inequality might become worse, exacerbating an already distressing scenario due to COVID-19. 10, 4153 (2021). In January 2021, Manaus witnessed one of the most tragic scenarios of overwhelmed hospital capacity, running out of not only hospital beds but also oxygen22.

Estimated change in e0 (c) and e65 (d) in 2021. Overall, the viscoelastic properties of the synthesized PSAs suggest they would be useful for applications such as removable general-purpose adhesives, including tapes, bandages, and sticky notes. Ellen MacArthur Foundation. Fagnani, D. E. et al. Diabetes Res. Similarly to Brazil, many other countries in Latin America experienced a relatively fast pace of mortality improvement during this period, benefitting from the public health and medical progress of their forerunners9,11. 3, e1700782 (2017). Nevertheless, the estimates might still suffer from incomplete and/or delayed reporting of deaths, especially those for 2021, with potential variation in completeness across states. Height influenced biomass accumulation and hence C gain, where life forms . 1a, Supplementary Table 1 and Methods), with a larger drop for males (1.57 years) than females (0.95 years). Genomics and epidemiology of a novel SARS-CoV-2 lineage in Manaus, Brazil. Slider with three articles shown per slide. Unfortunately, most used diapers sit in landfills without substantial biodegradation, or are incinerated. An alternative recycling route known as chemical recycling was developed to address these challenges8,9,10,11. Brazil continues to face a challenging situation. Because these data are not available by age and sex, we used de-identified publicly available data on severe acute respiratory illness (SARI) hospitalizations from the Influenza Epidemiological Surveillance Information System (Sistema de Informao de Vigilncia Epidemiolgica da Gripe, or SIVEP-Gripe, in Portuguese).

A facile and highly efficient strategy for esterification of poly(meth)acrylic acid with halogenated compounds at room temperature promoted by 1,1,3,3-tetramethylguanidine. Briefly, nonamers of polyacrylic acid were used as a model system along withbutanol Comparison of the reaction free energies was made between the first esterification and the final esterification. Third, because local health authorities have 60 d to report deaths from any cause, delayed death registration might be an issue in 2021, and, thus, for the first 4 months of 2021, we used confirmed COVID-19 deaths as reported by Brasil.io, which compiles epidemiological bulletins from the 27 state health departments. 75, 337345 (2002). CAS The results from both of these experiments demonstrate that the equilibrium lies far towards the esterification product. d, Number of COVID-19 deaths in 2020 per 100,000 people by state (Methods). Caruso, M. M. et al. Sci.

While catalytic depolymerization methods20 can, in principle, proceed without side-chain degradation, they have not yet been demonstrated for commercial sources of polyacrylic acid. (ed.) Woolf, S.

Manaus, the capital of Amazonas, observed a very high attack rate after the first wave of the pandemic in 2020 (ref. stream For decades, mechanical recycling has been used to recover some value from waste polymers, although recycling rates are low2 and the material quality is often reduced. As many countries speed up vaccination coverage and witness declines in cases and deaths, Brazil lags behind. To obtain 99, 99106 (2015). Adv.

A life cycle assessment demonstrates that the adhesives synthesized via this approach outcompete the same materials derived from petroleum feedstocks on nearly every metric, including carbon dioxide emissions and cumulative energy demand.

Giving superabsorbent polymers a second life as pressure-sensitive adhesives, https://doi.org/10.1038/s41467-021-24488-9. a, Estimated change in life expectancy at birth in 2020 based on the difference from life tables calculated for 2019 and 2020 by state and sex. Wernet, G. et al. A new variant of concern (P.1, now called Gamma), which emerged in the city in November 2020, is estimated to be 1.42.2 times more transmissible than other lineages, and at least 17% of the P.1 infections in Manaus in 2021 were reinfections23,24. Without a change in coordination of pandemic response, expansion of testing and a rapid increase in vaccination, Brazil will soon become a serious threat to national and global health security42. After more than 195,000 lives were reported to have been lost in 2020 to COVID-19, no policy changes have appeared in 2021. Also in May 2021, the first case of the Delta variant (B.1.617.2), first detected in India, was reported in Brazil26.

The magnitude of the COVID-19 death toll was not homogenous across states and was associated with the pattern of spread18. In both cases, the nonamers were solvated in a 3:1 butanol/water mixture to mimic the most challenging esterification conditions. DT19 and DT20 assess the effect of including and excluding, respectively, only deaths for which COVID-19 was listed as the underlying cause on the death certificate. Because this recycling method should be amenable to waste polymer as the feedstock, it offers a more sustainable alternative to diaper disposal in a landfill or incineration.

Fundao Oswaldo Cruz. Closed-loop chemical recycling via depolymerization to monomer is also not currently feasible for these superabsorbent materials because side-chain degradation outcompetes depolymerization. CAS A more limited version of the basic income program was re-established in April 2021. In 15 states (including the entire Southeast region), this loss was higher among males (Fig. Creton, C. Pressure-sensitive adhesives: An introductory course. Here we report an open-loop recycling method for these materials that involves (i) decrosslinking via hydrolysis, (ii) an optional chain-shortening via sonication, and (iii) functionalizing via Fischer esterification. All authors contributed to the interpretation of results and manuscript editing.
