Polymer–Metal Composites Materials for Healthcare Device
An ideal medical implant requires optimized properties on both bulk and microscopic scale that can hardly be accomplished by using a single material. Metallic implants such as titanium-based implants possess excellent mechanical properties in general but suffer from corrosion; polymeric implants can be multifunctional and biodegradable, however, difficult to provide some crucial mechanical properties like ductility. With the advance in polymer science and metallurgy, the polymer–metal composite materials serve as an emerging class of healthcare device with optimized bulk and microscopic properties, such polymer–metal composite devices provide good mechanical support, good bio-integration, good hygiene, and minimize bacterial infection and reduced hypersensitivity reactions.

Evolved Expendable Launch Vehicle
Evolved Expendable Launch Vehicle (EELV) is an expendable launch system program of the United States Air Force (USAF), intended to assure access to space for Department of Defense and other United States government payloads. The program, which began in the 1990s with the goal of making government space launches more affordable and reliable, resulted in the development of the Delta IV and Atlas V. Along with the newer Falcon 9, these launch systems are the primary methods for launching U.S. military satellites. The USAF plans to use the EELV family of launch vehicles until at least 2030. Follow-on technologies are being considered, one of which was the Reusable Booster System, discontinued in 2012.

Major High-Voltage Insulator Contamination Level Classification Techniques
Insulators are considered one of the most significant parts of power systems which can affect the overall performance of high-voltage (HV) transmission lines and substations. High-voltage insulators are critical for the successful operation of HV overhead transmission lines, and a failure in any insulator due to contamination can lead to flashover voltage, which will cause a power outage. The electrical performance of HV insulators is highly environment sensitive. The main cause of these flashovers in the industrial, agricultural, desert, and coastal areas, is the insulator contamination caused by unfavorable climatic conditions such as dew, fog, or rain. The different methods adopted to identify the contamination level on high-voltage insulators are discussed.

The Role of ALDH2 in Cardiovascular Disease Management
Mitochondrial aldehyde dehydrogenase 2 (ALDH2) is a cardioprotective enzyme that catalyzes the bio-activation of GTN to NO. Nitrate tolerance is accompanied by an increase in oxidative stress, endothelial dysfunction, and sympathetic activation, as well as a loss of the catalytic activity of ALDH2 itself. On the basis of current knowledge, nitrate intake in the diet would guarantee a concentration of NO such as to avoid (or at least reduce) treatment with GTN and the consequent onset of nitrate tolerance in the course of cardiovascular diseases, so as not to make necessary the increase in GTN concentrations and the possible inhibition/alteration of ALDH2, which aggravates the problem of a positive feedback mechanism.

Using Remote Sensing in Soil Salinization Mapping
Meeting current needs without compromising future generations’ ability to meet theirs is the only path toward achieving environmental sustainability. As the most valuable natural resource, soil faces global, regional, and local challenges, from quality degradation to mass losses brought on by salinization. These issues affect agricultural productivity and ecological balance, undermining sustainability and food security. Therefore, timely monitoring and accurate mapping of salinization processes are crucial, especially in semi-arid and arid regions where climate variability impacts have already reached alarming levels. Salt-affected soil mapping has enormous potential thanks to recent progress in remote sensing.

Accessible Higher-Education: A Framework for Continuous Improvement
The SARS-CoV-2 Coronavirus pandemic (COVID-19) forced educational institutions to move their programs to the virtual world, revealing needs such as the lack of accessibility of online resources and content. In this context, the Erasmus+ project "Technological Assistance to Accessibility in Virtual Higher Education (EduTech)”, proposed tools and knowledge focused on improving accessibility in Higher Education Institutions (HEIs). In this article, a framework that integrates all the findings of the EduTech project is presented. The proposed framework is aimed at facilitating the adoption of good practices related to technological accessibility in HEI. The framework considers the limitations and needs of the institutions in terms of governance and resources for improving accessibility. The framework was adopted by four Latin American HEIs to establish a continuous improvement strategy according to their needs and current level of accessibility focus. This research also shows the results and suggests that the proposal is adaptable to the needs of HEIs, allowing its implementation regardless of their organizational structure and their current level of attention to accessibility.

Vegetarian Diets and Chronic Kidney Disease Complications
A growing body of evidence has demonstrated that higher consumption of plant-based foods and the nutrients found in vegetarian and plant-based diets are associated with numerous health benefits, including improved blood pressure, glycemic control, lipid levels, body mass index, and acid–base parameters. Furthermore, there has been increasing recognition that vegetarian and plant-based diets may have potential salutary benefits in preventing the development and progression of chronic kidney disease (CKD). While increasing evidence shows that vegetarian and plant-based diets have nephroprotective effects, there remains some degree of uncertainty about their nutritional adequacy and safety in CKD (with respect to protein-energy wasting, hyperkalemia, etc.).

Aneurysm prevention in Kawasaki Disease
 A form of systemic vasculitis that affects mostly small and medium-sized vessels, Kawasaki disease (KD) is most commonly found in children under the age of 5 years old. Though its etiology is unknown, KD has been the most frequent acquired heart disease in developing countries. The most severe complications of KD are coronary artery lesions (CAL), including dilation, fistula, aneurysm, arterial remodeling, stenosis, and occlusion. Aneurysm formation has been observed in 20-25% of KD patients that do not receive intravenous immunoglobulin (IVIG) treatment, and in 3-5% that do receive it. Coronary artery dilation has been found in about 30% of KD patients in the acute stage, although mostly in the transient form. Diminishing the occurrence and regression of aneurysm is a vital part of treating KD. This review is focuing on coronary artery aneurysm prevention in KD.

Radiation Therapy
Tumor radioresistance is associated with a failure to achieve loco-regional disease control following radiotherapy with the highest acceptable doses. Radiobiology research focused on tumor radioresistance has pointed out several mechanisms attenuating the efficacy of tumor irradiation and several treatment answers to overcome such radio-resistance. Personalized medecine allows us to adapt the treatment to diseases according to patient specificities and characteristics. Novel radiotherapy such as heavy ion therapy enable a better balance between high doses to the tumor and low doses to the surrounding healthy tissues.

Multidrug Resistant Gram-Negative Bacteria
Antibiotic resistance has increased markedly in Gram-negative bacteria, causing severe infections intractable with traditional drugs and amplifying mortality and healthcare costs. Consequently, to find novel antimicrobial compounds, active on multidrug resistant bacteria, is mandatory. In this regard, cationic antimicrobial peptides (CAMPs)—able to kill pathogens on contact—could represent an appealing solution. However, low selectivity, hemolytic toxicity and cost of manufacturing, hamper their massive clinical application. In the recent years—starting from CAMPs as template molecules—less toxic and lower-cost synthetic mimics of CAMPs, including cationic peptides, polymers and dendrimers, have been developed. Although the pending issue of hemolytic toxicity and biodegradability is still left not completely solved, cationic antimicrobial polymers (CAPs), compared to small drug molecules, thanks to their high molecular weight, own appreciable selectivity, reduced toxicity toward eukaryotic cells, more long-term activity, stability and non-volatility. With this background, an updated overview concerning the state of the art of the main manufactured types of CAPs, active on Gram-negative bacteria, is herein reported, including synthetic procedure and action’s mechanism. Information about the antibacterial activity, advantages and drawbacks of the most appealing compounds was also provided.

Discriminative Measurement for Radon Isotopes
Radon and thoron measurement studies have been widely conducted and reported all over the world. Generally, the techniques used relate to the passive nuclear track detectors. Though some surveys shown that passive monitors for radon are sensitive to thoron, and hence the measured results might be probably overestimated the radon concentration. This study investigated the radon and thoron measurement in domestic and international using passive radon-thoron discriminative measuring device, commercially named RADUET. This paper attempts to provide an understanding and evident roadmap for discriminative measurements of radon isotopes.
