More positive North Atlantic Oscillation cools the subpolar North Atlantic in the past century

Published: October 2022

Abstract
Sea surface temperature (SST) in the subpolar North Atlantic has significantly decreased at a rate of -0.39 (\(\pm 0.23\)) K/century during 1900–2020, which runs counter to global warming due to anthropogenic forcing. The cooling in the subpolar North Atlantic, known as the North Atlantic cold blob, could be driven by a host of mechanisms involving both the ocean and atmosphere. Here, we present evidence that changes in the atmospheric circulation over the North Atlantic, in particular a centennial trend towards a more positive phase of the North Atlantic Oscillation (NAO), could have contributed to the cold blob. The positive NAO intensifies the surface wind over the subpolar North Atlantic and induces excessive heat loss from the air-sea interface. According to an idealized mixed layer heat balance model, the NAO induced heat loss alone cools the subpolar North Atlantic by 0.26 K/century, which explains 67% of the observed cold blob SST trend. Thus, besides ocean circulation, including the slowdown of the Atlantic Meridional Overturning Circulation, the large-scale atmospheric circulation might have played an equally important role in prompting the century-long SST changes in the subpolar North Atlantic.

Published: October 2022

Monitoring of cardiospecific markers is significant during intensive care.The objective: to compare the diagnostic and prognostic significance of cardiac markers in newborns with somatic and surgical pathology.Subjects and Methods. The study included 76 newborns aged 1 to 14 days with somatic or surgical disorders. The changes in the concentration of cardiomarkers in newborns and their relationship with echocardiography data and non-invasive hemodynamic parameters are presented, their prognostic ability is assessed.Results. Rigidity of non-invasive hemodynamic parameters, and echocardiography data was revealed. In the somatic group, regression of NT-proBNP from 8,307 ng/ml (3,600; 9,000) to 1,717 ng/ml (1,041; 5,011) was regarded as a marker of resolution of hypervolemia against the background of cardiovascular maladaptation. The increase in NT-proBNP from 4,710 ng/ml (3,400; 6,989) to 7,987 ng/ml (3,397; 9,000) in the postoperative period requires a revision of the infusion therapy program with the priority of volume restriction.Conclusions. Stabilization of the condition of patients in the groups is accompanied by a decrease in the concentration of markers of myocardial tension (MB-fraction of creatine phosphokinase, troponin T).Measurement of NT-proBNP concentration allows assessment of fluid overload in critically ill neonates.

Published: October 2022

As micro e pequenas empresas desempenham um papel de extrema importância na dinâmica e no desenvolvimento econômico e social do país, e, apesar da tendência de multiplicação destes estabelecimentos, observa-se uma dificuldade de sua perpetuação. O objetivo deste trabalho foi estudar os aspectos relacionados à sobrevivência desses estabelecimentos. Foram analisados os fatores de sucesso ou fracasso para melhor entender os que influenciam direta ou indiretamente a permanência desses negócios no mercado. Para isso, foi feita inicialmente uma pesquisa bibliográfica sobre o assunto, levantando dados sobre os condicionantes do sucesso das micro e pequenas empresas. Posteriormente, foi escolhida o município de Pedro Leopoldo/MG, onde realizou-se uma pesquisa de abordagem qualitativa, do tipo descritiva, por meio da aplicação de questionários a empresários locais, visando identificar as características das empresas, perfil dos gestores, percepção dos mesmos sobre dificuldades enfrentadas, fatores de sucesso dos negócios, além de questões relacionadas ao efeito da pandemia COVID – 19. Os resultados obtidos sugerem que as principais dificuldades encontradas pelos empresários estão ligadas a fatores econômicos, como a carga tributária e as taxas de juros elevadas e a recessão econômica. Uma boa estratégia de vendas e bom conhecimento do mercado onde atua, aliados a características pessoais do empresário, como criatividade, capacidade de liderança, persistência e de assumir riscos, em conjunto, demonstram ser fundamentais para o bom desempenho empresarial, conforme esta pesquisa.

The effect of coconut water consumption on the post exercise recovery heart rate AbstractThis study aims to determine the effect of giving coconut water to the recovery pulse after physical activity. This study used a quasi experiment design with a pretest post test control group design. The subjects of this study were 10 subjects who were not athletes, aged 16-20 years who were not injured or treated by a doctor, did not take supplements of sources of vitamins and minerals. Or supplements that function as power plants as long as the research takes place and are willing to take part in the research. The results of the examination of the pulse recovery control group showed an average value of the pre-test pulse 140 / minute. While the post test shows the average recovery pulse rate of 156 / minute. So it can be concluded that there is no effect of giving mineral water to the recovery pulse after physical activity. By consuming 350 mL of coconut water 30 minutes before doing physical activity can accelerate the rate of recovery pulse.
