Endoscopic Ultrasonography in Children with Eosinophilic Esophagitis—A Review

Endoscopic ultrasonography (EUS) is a diagnostic endoscopy of the upper gastrointestinal tract, during which ultrasound of nearby organs is also performed. It is also possible to perform a fine needle aspiration biopsy. Currently, EUS is performed more frequently in adults. Despite some limitations, this diagnostic method is also more and more often performed in pediatric patients. Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus, which also occurs in children, and leads to irreversible fibrosis of the esophagus wall, if left untreated. Traditional methods of diagnosing and monitoring EoE treatment have significant limitations, and the use of EUS and total esophageal wall thickness (TWT) assessment may bring measurable benefits. Several studies have shown an increased thickening of TWT in EoE in children compared to pediatric patients with gastroesophageal reflux disease, and a decrease in TWT in adults who responded to EoE treatment. These results suggest that EUS and TWT measurement may become an important test in diagnostics, monitoring the effectiveness of therapy, assessing disease progression, and in individualizing the method and duration of EoE treatment also in children.

A Review of Microplastics Risk Assessment in the Coastal Environment

Pollution from microplastics has recently become a prevalent threat to the ecosystem. Microplastics with a dimension less than or equal to 5 mm are smaller. There are many ways that microplastics can reach the atmosphere. By various mechanisms, the breakdown of macro plastics will happen. Chemical degradation, tire abrasion, is the most common forms of degradation. Microplastics (MPs) pollution in the coastal and marine ecosystem is currently a global problem. Transferring MPs from land to sea and allowing them to enter the food chain has a direct negative impact on marine life and human health. The combined toxicity effects of MicroPlastics (MPs) and other contaminants in marine environments, as well as their toxicity effects and mechanisms based on a variety of environmentally important test organisms, were also covered in this study.

Serendipity or a Missed Chance? On the Interaction Between Vaccine Distribution and the EU Recovery Funds

In this article, we discuss the interaction between the Covid-19 vaccine rollout in EU member states and the effective use of grants and soft loans from the EU pandemic recovery fund. With some of the national spending plans for the Recovery Fund still awaiting initial submission (Bulgaria), others pending the Commission’s endorsement (Poland, Hungary) or formal Council’s approval (Romania, Estonia), and various other national plans in their implementation stage, the next challenge for policymakers will be to ensure that the initial and subsequent tranches of EU funds are released as economies reopen. We claim that special attention ought to be paid to Central and Eastern Europe, where some countries are lagging in their vaccine rollout and/or the preparation for their use of the EU recovery funds. This is likely to be an important test for EU institutions in determining the stability and coherence of the European project as a whole.

Application of Cohesion Theory in CET-4 Listening Comprehension

Cohesion is a very important part of learning English. The Cohesion Theory of Halliday and Hasan is of great importance for people to acquire the knowledge of cohesion. This study is aimed at applying this Cohesion Theory in CET-4 listening comprehension which is an important test for Chinese college students. This study uses the test papers of CET-4 in June 2021 as examples to demonstrate that it is obvious that there are certain cohesive relations between the listening materials and the correct answers. It is also practicable to apply the Cohesion Theory in listening comprehension of CET-4. It mainly analyzes the cohesive devices applied in figuring out the correct choices by understanding the cohesive relations between the listening materials with the right answers. It demonstrated obviously that there exists the cohesive relations between the listening materials with the right answers in the test, and both the grammatical device and lexical device are often used interactively. The cohesive devices can serve as the important clues for students to make the right choices. The findings of this study suggest that the application of the Cohesion Theory in CET-4 listening comprehension is practicable and effective. It can not only help the students get good performance in the CET-4 tests, the same approach can also be used in other important tests. 

ENSAIO NÃO DESTRUTIVO (END) DE ANÁLISE DE VIBRAÇÕES APLICADO À MANUTENÇÃO PREDITIVA

Predictive maintenance consists of monitoring data obtained from monitoring, with the main results of increasing the availability and reliability of equipment. Several non-destructive testing can be performed by this type of maintenance, with vibration analysis being one of the most common. The aim of this study is to evaluate the relevance of vibration analysis in the context of industrial predictive maintenance, as well as its applicability in mechanical and electrical equipment. The scientific production of this article was based on the experiments carried out by several authors in their areas of expertise, based on bibliographic source. It was concluded that the vibration analysis is an important test for the application of predictive maintenance, being able to be implemented in several equipments, besides being a method that contributes directly to the reduction of costs in the supply chain. Finally, it is necessary to take into account that there are points of attention that must be considered for a more adequate implementation of the method.

Pancreatic lipase: why laboratory community does not take enough care of this clinically important test?

Although being the recommended laboratory test to diagnose acute pancreatitis, serum pancreatic lipase (LIP) is among the poorly standardized laboratory tests, and laboratory stakeholders often appear to not take enough care of the quality of its measurements. Here we discuss some important issues that, if not correctly managed and solved, make misdiagnosis of acute pancreatitis by using serum LIP a real possibility. First, the current unavailability of a suitable higher-order reference material to be used as common calibrator should be filled up to definitively improve the inter-method bias. Second, knowledge of the analytical characteristics that may explain the defective performance of LIP assays should be deepened. IVD manufacturers should be more explicit in providing this information, including description of their internal protocol for transferring LIP values from internal references to commercial calibrators. Third, recommended models for accurately estimating measurement uncertainty and reliably defining analytical performance specifications for LIP measurements should be applied. Finally, investments considering alternative options for measuring LIP (e.g., targeted to the development of automated LIP immunoassays) should be warranted. All involved stakeholders (standardization bodies, higher-order reference providers, in vitro diagnostics manufacturers, and laboratory professionals) should contribute to fill the existing gap.

Leak Testing

While the exercise of pressurizing a piping system and checking for leaks is sometimes called pressure testing, the Code refers to it as leak testing. The main purpose of the test is to demonstrate that the piping can confine fluid without leaking. When the piping is leak tested at pressures above the design pressure, the test also demonstrates that the piping is strong enough to withstand the pressure. For large bore piping where the pipe wall thickness is close to the minimum required by the Code, being strong enough to withstand the pressure is an important test. For small bore piping that typically has a significant amount of extra pipe wall thickness, being strong enough is not in question. Making sure that the piping is leak free is important for all piping systems.

Advertisement Click Fraud Detection

Mobile ads are tormented with deceitful clicks that may be an important test for the advertising network. Albeit documented promotion systems utilize various methods to acknowledge click fraud, they don’t shield the client from conceivable intrigue among distributors and advertisement systems. What’s additional, promotion systems can’t screen the client’s action for click fraud location once they're entertained to the advertising web content following clicking the ad, i.e., in a web site there will be focuses or some specific spots after we click on the actual spot it'll be entertained to the advertising web site. We propose another publically support-based mostly framework referred to as Click Fraud Crowdsourcing (CFC) that works in conjunction with the two promoters and advertisement organizes therefore as to defend the two gatherings from any conceivable click dishonorable acts. The framework profits by each a worldwide view, wherever it accumulates various promotion demands examining to various advertising organize distributer publicist blends, and a nearby read, wherever it will follow the clients’ commitment in every advertising website.

Review and Assessment of the Effect of Hydrogen Gas Pressure on the Embrittlement of Steels in Gaseous Hydrogen Environment

Hydrogen gas pressure is an important test parameter when considering materials for high-pressure hydrogen applications. A large set of data on the effect of hydrogen gas pressure on mechanical properties in gaseous hydrogen experiments was reviewed. The data were analyzed by converting pressures into fugacities (f) and by fitting the data using an f|n| power law. For 95% of the data sets, |n| was smaller than 0.37, which was discussed in the context of (i) rate-limiting steps in the hydrogen reaction chain and (ii) statistical aspects. This analysis might contribute to defining the appropriate test fugacities (pressures) to qualify materials for gaseous hydrogen applications.
