Receita pública e bem-estar social nos municípios mineiros emancipados no período de 1988 a 1997

O movimento de descentralizações política, administrativa e fiscal intensificado a partir de 1988 tinha como objetivo promover a transferência de poder, recursos e atribuições para os governos locais. Além disso, esse fenômeno impulsionou o processo de emancipação municipal com o intuito de aproximar o poder público da sociedade, promovendo a melhoria da prestação de serviços. Este estudo apresenta a análise das receitas públicas e do bem-estar social dos municípios mineiros emancipados no período de 1988 a 1997. Para tanto, utilizaram-se testes de médias no intuito de comparar o desempenho dos municípios emancipados com o desempenho de seus municípios de origem. Como conclusão, verificou-se que os novos municípios são beneficiados com as transferências governamentais e possuem a mesma capacidade de arrecadação tributária dos seus municípios de origem. Não obstante, isso não permitiu que os citados municípios apresentassem nível de bem-estar superior em relação aos municípios de origem, assim como maior eficiência na gestão desses recursos, uma vez que estão mais próximos dos usuários

Ba+2 ion trapping using organic submonolayer for ultra-low background neutrinoless double beta detector

If neutrinos are their own antiparticles the otherwise-forbidden nuclear reaction known as neutrinoless double beta decay can occur. The very long lifetime expected for these exceptional events makes its detection a daunting task. In order to conduct an almost background-free experiment, the NEXT collaboration is investigating novel synthetic molecular sensors that may capture the Ba dication produced in the decay of certain Xe isotopes in a high-pressure gas experiment. The use of such molecular detectors immobilized on surfaces must be explored in the ultra-dry environment of a xenon gas chamber. Here, using a combination of highly sensitive surface science techniques in ultra-high vacuum, we demonstrate the possibility of employing the so-called Fluorescent Bicolor Indicator as the molecular component of the sensor. We unravel the ion capture process for these molecular indicators immobilized on a surface and explain the origin of the emission fluorescence shift associated to the ion trapping

A Computer Model for the Generation of Visual Compositions

This paper describes a computer model for visual compositions. It formalises a series of concepts that allows a computer agent to progress a visual work. We implemented a prototype to test the model; it employs letters from the alphabet to create its compositions. The knowledge base was built from examples provided by designers. From these examples the system obtained the necessary information to produce novel compositions. We asked a panel of experts to evaluate the material produced by our system. The results suggest that we are in the right track although much more work needs to be done

Use of N-acetylcysteine plus simethicone to improve mucosal visibility in upper digestive endoscopy via systematic alphanumeric-coded endoscopy: a randomized, double-blind controlled trial

Background The use of antifoaming and mucolytic agents prior to upper gastrointestinal (GI) endoscopy and a thorough systematic review are essential to optimize lesion detection. This study evaluated the effect of simethicone and N-acetylcysteine on the adequate mucosal visibility (AMV) of the upper GI tract by an innovative systematic method. Methods This randomized, double-blind controlled trial included consecutive patients who underwent diagnostic upper GI endoscopy for screening for early neoplasms between August 2019 and December 2019. The upper GI tract was systematically assessed by systematic alphanumeric-coded endoscopy. Patients were divided into 4 groups: 1) water; 2) only simethicone; 3) N-acetylcysteine + simethicone; and 4) only N-acetylcysteine. The following parameters were assessed in each group: age, sex, body mass index, level of adequate mucosal visibility, and side-effects. Results A total of 4564 images from upper GI areas were obtained for evaluation. The mean AMV in the 4 groups was 93.98±7.36%. The N-acetylcysteine + simethicone group had a higher cleaning percentage compared with the other groups (P=0.001). There was no significant difference among the remaining groups, but several areas had better cleaning when a mucolytic or antifoam alone was used. No side-effects were found in any group. Conclusion The combination of N-acetylcysteine plus simethicone optimizes the visibility of the mucosa of the upper GI tract, which could potentially increase diagnostic yield. © 2024 Hellenic Society of Gastroenterology
