Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

Assessment of risk factors for congenital heart disease through prenatal fetal echocardiography and the correlation with postnatal diagnoses

Background: Congenital Heart Disease (CHD) constitutes a significant cause of morbidity and mortality in newborns. Identifying CHD prenatally and understanding associated risk factors can aid in early diagnosis, intervention, and postnatal management. This study aims to assess risk factors for CHD using prenatal fetal echocardiography (FE) and investigate their correlation with postnatal diagnoses. Patients and Methods: In this study, we included 993 pregnant women presenting to the pediatric cardiology outpatient clinic between December 2018 and December 2020, considered at risk for CHD. We retrospectively evaluated the cases’ postnatal echocardiography data with detected CHD during fetal echocardiography. Results: The average age of the patients was 29.8±5.7, and the mean gestational week was 23.61±3.9. Among the pregnant women, 253 (25.47%) were primiparous, 740 (74.53%) were multiparous, 103 cases (9.32%) involved multiple pregnancies, and 259 (26.08%) had chronic diseases. The most common reason for fetal echocardiography referral was the suspicion of CHD in fetuses with dysmorphic findings detected during obstetric ultrasonography. Among the cases, 329 (33.1%) were classified as low-risk, while 664 (66.9%) as high-risk. Among all patients, the most commonly observed prenatal CHD were Ventricular Septal Defects (VSD) (8.2%), Hydrops Fetalis (6.1%), and large Atrial Septal Defects (ASD) (3.9%). The overall prevalence of CHD was 31.6%. The accuracy of postnatal echocardiography in confirming the diagnoses made with fetal echocardiography was 94%. Conclusion: Prenatal diagnosis of congenital heart diseases is crucial for planning prenatal and postnatal management and providing families with the option of pregnancy termination in severe anomalies. Fetal echocardiography has shown significant potential for early diagnosis of CHD, even in low-risk fetuses, and its inclusion in routine prenatal screenings by increasing the number of experienced specialists and centers could play a crucial role in reducing CHD-related mortality and morbidity rates

Measurement of the charge ratio of atmospheric muons with the CMS detector

We present a measurement of the ratio of positive to negative muon fluxes from cosmic ray interactions in the atmosphere, using data collected by the CMS detector both at ground level and in the underground experimental cavern at the CERN LHC. Muons were detected in the momentum range from 5 GeV/ c to 1 TeV/ c . The surface flux ratio is measured to be 1.2766±0.0032(stat.)±0.0032(syst.) , independent of the muon momentum, below 100 GeV/ c . This is the most precise measurement to date. At higher momenta the data are consistent with an increase of the charge ratio, in agreement with cosmic ray shower models and compatible with previous measurements by deep-underground experiments.We present a measurement of the ratio of positive to negative muon fluxes from cosmic ray interactions in the atmosphere, using data collected by the CMS detector both at ground level and in the underground experimental cavern at the CERN LHC.

Transverse-momentum and pseudorapidity distributions of charged hadrons in pppp collisions at s\sqrt{s} = 7 TeV

Charged-hadron transverse-momentum and pseudorapidity distributions in proton-proton collisions at $\sqrt{s} = 7$~TeV are measured with the inner tracking system of the CMS detector at the LHC. The charged-hadron yield is obtained by counting the number of reconstructed hits, hit-pairs, and fully reconstructed charged-particle tracks. The combination of the three methods gives a charged-particle multiplicity per unit of pseudorapidity \dnchdeta|_{|\eta| < 0.5} = 5.78\pm 0.01\stat\pm 0.23\syst for non-single-diffractive events, higher than predicted by commonly used models. The relative increase in charged-particle multiplicity from $\sqrt{s} = 0.9$ to 7~TeV is 66.1\%\pm 1.0\%\stat\pm 4.2\%\syst. The mean transverse momentum is measured to be 0.545\pm 0.005\stat\pm 0.015\syst\GeVc. The results are compared with similar measurements at lower energies.Charged-hadron transverse-momentum and pseudorapidity distributions in proton-proton collisions at sqrt(s) = 7 TeV are measured with the inner tracking system of the CMS detector at the LHC.
