Published: July 2020

Introduction: Heterogeneous Fenton is one of the Advanced Oxidation Processes (AOPs) and has been proven to be effective on azo dye degradation. However, a low-cost catalyst and factors affecting the processes of this system were further investigated.
Methods: In this study, pellets of iron alumina pillared bentonite (PFeAPB) were prepared by dispersing iron ions on alumina pillared bentonite pellet. Catalyst activity and lifetime were investigated via efficiencies of Methyl Orange (MO) decolorization and Chemical Oxygen Demand (COD) removal, a typical dye type of textile wastewater. Characteristics of the PFeAPB catalyst were examined by X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) surface area, and X-ray fluorescence (XRF).
Results: Results of batch experiments showed that specific surface area of the PFeAPB catalyst was 111.22 m2/g higher than its precursor by 2 times (57.79 m2/g). Goethite, Hematite and Maghemite phases with approximately 11.5% of iron elements containing in the catalyst were detected via XRD and XRF. Experimental conditions of pH, initial MO solution, Hydrogen Peroxide concentration, reaction time and catalyst loading were 2.0 ± 0.1, 12.7 mmol/L, 150 min and 20 g/L, respectively, to achieve 88.68 ± 5.69% of MO decolorization and 50.27 ± 6.05% of COD removal while dissolved iron in this heterogeneous Fenton process was below standard limit (2 ppm). Catalyst activity decreased by 5.22% in decolorization efficiency after the two first reusages.
Conclusion: These primary results showed the potential of applying PFeAPB catalyst in heterogeneous Fenton process with low iron leaching into water.

We evaluate how the Indonesian stock market has reacted to the banking diversification revenue strategy in the period of 2009-2016. The market reactions are measured by the ratio of market equity capitalization to its book value equity (MB) and market viability or solvency is proxied by the bank’s market-based Z score. Using panel data regression, we find that the higher the level of diversification of bank revenue response positively by the market indicating by improving on banks’ capitalization ratio and market solvency. It shows that revenue diversification could produce a significant impact on bank profitability and reduce the probability of bank failure. Additionally, our results reveal that the larger size of the bank, the riskier the bank, however,these larger banks could achieve higher market equity capitalization that protects them from insolvency problems. Banks having large book equity capital response positively by the market, it indicates a positive relationship between this variable and Z score.

now the enterprise of heat power engineering represents the interconnected complex of technical means, de-vices and mechanisms which main purpose-accumulation and transfer of energy to the final consumer. Due to the specifics of its work at each stage of the thermal power plant performed a variety of tasks. Depending on the tasks, the system of the complex itself is formed with the selection of installations, energy storage facilities, as well as treatment facilities. In the process of realization of their direct functions, such enterpris-es have an impact on the environment, which is rather negative. Therefore, the problem of interaction be-tween heat and power enterprises and the environment is particularly acute.
Both the work of the enterprise itself and the work on its construction cause irreparable harm to the envi-ronment. Plant interventions such as fuel selection and energy conversion efficiency measures reduce emis-sions of many air pollutants, including CO2, per unit of energy generation. Optimization of energy efficiency in the generation process depends on many factors. However, it is impossible to make the enterprise com-pletely environmentally friendly for many reasons, however, it is necessary to assess correctly the possible risks of operation of this type of production and take adequate measures to minimize the harm caused to the environment.

Due to Covid -19 Pandemic educational institutions have closed in 107 countries affecting more than 860 million students. Information and communications technology have been widely adopted in most educational institutions in order to support e-learning through different learning methodologies. Information and communication technologies have changed the face of managing information in crisis, warning, impact and response. Information and communication technologies are changing the way that users are responding to environmental and health disruptions. In conflict zones it is dangerous for people to travel and maintain normal activities. However with mobile phones and internet applications and data on cloud, people can coordinate and communicate to help restore activities through negotiating travel, increasing situational awareness and conducting online social interaction. Security and compliances have become the key and mandatory for the organisation as data is growing in exponential form. Privacy laws applies not only to government operations but also to private enterprises and commercial transactions to understand how user data is being handled, processes to customer and visitor. It exploits to keep certain data confidential and if exposed it has to be with consent of user. Crisis management is designed to protect an organization and its stakeholders from threats and/or reduce the impact felt by threats. All the stages has discussed in detail along with diagram keeping concern in a crisis has to be public safety. A failure to address public safety intensifies the damage from a crisis. Reputation and financial concerns are considered after public safety has been remedied.

Published: July 2020

Background: Optimal timing for CABG surgery after myocardial infarction remains a matter of debate. The aim of our study was to analyze the effect of timing of CABG after acute myocardial infarction on operative mortality and morbidity.
Methods: This prospective study included 60 patients who underwent isolated CABG within 30 days of acute myocardial infarction over 20 months (from the first of November 2014 till the end of June 2016) in Kasr Al-Ainy University Hospitals. Patients were divided into two groups; the early group (0 – 3 days) included 14 patients (23.3%) and the late group (4 – 30 days) included 46 patients (76.7%). The primary outcome was all-cause hospital mortality.
Results: Our study included 43 males (71.7%) and 17 females (28.3%). The mean age was 58.4 ± 7.3 years. The total mortality rate was 8.3%. Patients undergoing early CABG experienced a higher mortality rate than those undergoing late CABG (21.4% vs 4.3%, P = 0.043). Also, early CABG was associated with more postoperative complications. Cardiogenic shock and early CABG were independent risk factors of mortality.
Conclusion: CABG in the first 3 days after acute myocardial infarction was associated with high mortality and morbidity in comparison with late CABG. This suggests that CABG may best be deferred for more than 3 days after acute MI in non-urgent cases.

Published: July 2020

Background: Mitral valve diseases are commonly associated with pulmonary hypertension. The aim of this study was to evaluate the effect of preoperative administration of sildenafil on the outcome after mitral valve replacement in patients with pulmonary hypertension.
Methods: This prospective randomized study was carried out on 67 patients who had a mitral valve replacement and associated high systolic pulmonary artery pressure more than 50 mmHg. Patients were randomized into three groups: group A (n= 20) received preoperative sildenafil for one week, group B (n=22) received sildenafil for one month, and group C (n= 25) did not receive sildenafil. All patients had transthoracic echocardiography preoperatively, one week and one month postoperatively.
Results: There was no difference in preoperative and operative variables among groups. Dobutamine support was required in 15 patients (60%) in group C vs. 6 patients (30%) in group A and 5 patients (22.5%) in group B (p= 0.012). Duration of mechanical ventilation was significantly longer in group C (389.2 ± 48.79 minutes) compared to group A and B (295.5 ± 17.01 and 281.4 ± 39.44 minutes, respectively, p<0.001). ICU stay was longer in group C (61.72 ± 13.69 hours) compared to groups A and B (53.55 ± 14.49 and 45.64 ± 13.43 hours, respectively, p=0001). The hospital stay was longer in group C (8.0 ± 1.80 days) compared to group A and B (6.05 ± 0.94 and 6.27 ± 1.24 days, respectively; p< 0.001). The transthoracic echocardiographic study one month after the operation showed that pulmonary artery systolic pressure significantly lower in groups A and B (28.30 ± 3.3 and 28.2 ± 4.98 mmHg, respectively) compared to group C (43.12 ± 4.99 mmHg) (p <0.001). There was no statistically significant difference between groups A and B regarding PASP after five days (p= 0.287) or one month (p= 0.939).
Conclusion: We found that preoperative administration of oral sildenafil in patients with pulmonary hypertension undergoing mitral valve replacement may reduce pulmonary hypertension postoperatively. We could not find a difference in the administration of sildenafil for either one week or one month preoperatively.

Published: July 2020

Background: Pericardial effusion and tamponade are common following valve surgery. The optimal treatment of symptomatic pericardial effusions remains controversial. The objective of this study was to present our experience in non-surgical management of delayed postoperative pericardial effusion.
Methods: This retrospective study was conducted on 64 patients who had delayed pericardial effusion after cardiac surgery from 2016 to 2020. Eight patients were excluded due to the presence of inaccessible posterior or clotted pericardial effusion and were managed surgically, and 56 patients had percutaneous drainage of the pericardial fluid and were included in the analysis.
Results: The mean age was 46.84±11.67 years (range: 22- 68 years), and 46.43% were females. The patients had coronary artery bypass grafting (n= 9), Aortic valve replacements (n= 13), Mitral valve surgery (n= 21), double valve replacements (n= 8) and combined procedures (n= 5). All patients complained of varying degrees of exertional dyspnea. There were statistically significant differences between INR in different cardiac surgeries. Mean INR following mitral valve replacement (4.72±0.63) was significantly higher than in aortic valve replacement patients (3.32±0.34; p<0.001) and aortic valve patients (1.76±0.24; p<0.001). Fifteen patients (26.78%) had a large pericardial effusion. Successful drainage was achieved in all cases. Complications were pneumothorax (n= 2, 3.57%), recurrent effusions (n= 4, 7.14%), arrhythmias (n= 7, 12.5%), myocardial punctures (n= 2, 3.57%) and no mortality was reported.
Conclusions: percutaneous drainage of postoperative pericardial effusion under radiological guidance is generally safe. Pericardial effusion is common after mitral valve surgery, which could be related to higher INR in these patients.

A gamificação enquanto função educativa é um excelente método alternativo para propiciar o ensino-aprendizagem do educando, por ser uma metodologia ativa e motivadora, com resultados positivos em todos os artigos revisados que aplicaram metodologias com gamificação no ambiente escolar. Desta forma, o presente artigo destaca a necessidade de se chegar ao estado da arte da gamificação combinada com a educação. Laboriosamente, o estado da arte foi alcançado com metodologia própria, fundada em três indagações a serem respondidas com auxílio de 22 pesquisas revisadas. As citadas indagações a serem respondidas são: (a) qual a conceituação de gamificação? (b) qual importância de pesquisar a gamificação no contexto educacional? e (c) por que a gamificação deve ser utilizada como recurso didático na educação? O primeiro critério situa o leitor quanto à origem e a conceituação da gamificação. A importância de pesquisar a gamificação indica o que torna o assunto relevante dentro do mundo acadêmico. O último questionamento revela o porquê a gamificação é utilizada como recurso didático na educação. Para atingir o estado da arte na área, foi necessário tirar proveito da seleção de periódicos indexados na forma de artigo da plataforma de diretórios de periódicos CAPES/MEC, acolhendo artigos de qualquer ano e de qualquer idioma. Foi utilizada nas buscas a combinação do termo “gamificação” aos termos “educação” e “ensino”, assim como seus derivados (ex.: ensino-aprendizagem e recurso didático).
