The process of metal additive manufacturing (AM) involves creating strong, complex components by using fine metal powders. Extensive use of AM methods is expected in near future for the production of small and medium-sized batches of end-use products and tools. The ability to detect loads and defects would enable AM components to be used in critical applications and improve their value. In this study, the Surface Response to Excitation (SuRE) method was used to investigate wave propagation characteristics and load [...]

Understanding the pathophysiology of disease can be an essential step to determining where and how to intervene for preventive or corrective health. Intrauterine growth restriction (IUGR) has been defined in livestock species as impaired gestational development of a fetus or its parts [1]. This broad category of ailments described by low fetal weight is accompanied by susceptibility to adult onset of chronic disease through fetal programming of numerous organ systems and their functions. This concern affects humans [...]

Catalytic pyrolysis is an attractive alternative for converting biomass into energy and chemicals to replace fossil sources. This has encouraged the search for efficient catalysts that can directly remove oxygenated products during pyrolysis, since they are the main problem in the processing and use of the products obtained. The catalytic and non-catalytic pyrolysis of medium density fiber (MDF) over beta zeolite-supported nickel (3 and 5%) was performed using the biomass/catalyst of 1.0/0.2 ratio. The thermokineti [...]

Adverse and traumatic childhood experiences can have profound negative health and mental health consequences across the lifespan. Prevention and early intervention strategies to mitigate such impacts and foster resilience are essential, yet extant approaches often do not consider the systemic nature of trauma exposure, particularly among communities most impacted by the COVID-19 pandemic and historic disinvestment. Addressing the impacts of trauma early in life is critical in order to mitigate their long-term effec [...]

Patients in the intensive care unit are confronted with an extreme situation that may cause stress and anxiety. The negative experiences may cause patients to suffer for the long-term after leaving the intensive care unit. One such stressor in the intensive care unit is non-invasive ventilation. Positive therapeutic suggestions under hypnosis can help patients in intensive care to enhance their well-being by helping them to deal with specific stress like being ventilated. The aim of our study is to assess the effec [...]

Pneumocystis jirovecii is an atypical fungus transmitted via the airborne route between humans. This fungus is exclusively associated with humans and almost each individual has encountered it at least once before reaching the age of two. P. jirovecii can be cleared and spontaneously resolutive in immunocompetent, whereas it can be responsible for severe Pneumocystis pneumonia (PCP) in immunocompromised patients. In the next decades, the putative increase of the population of immunocompromised patients is likely to [...]

The current status of a project is described which aims to demonstrate the technical and economic feasibility of converting the vast wind energy available over the globe’s oceans and lakes into storable energy. To this end, autonomous high-performance sailing ships are equipped with hydrokinetic turbines whose output is stored either in electric batteries or is fed into electrolysers to produce hydrogen which then is compressed and stored in tanks. In the present paper, the previous analytical studies which showed [...]

In the U.S., older adults aged 65 or above comprise nearly one quarter of the solid organ transplant (SOT) waitlists, and the number of transplants performed in this age group continues to increase. There are no specific guidelines for the assessment and follow up of the older SOT candidate or recipient. Older adults are at increased risk of infectious complications after SOT. Despite these complications and even with the use of suboptimal donors, overall outcomes are favorable. We provide an overview to specific c [...]

Performance degradation, including system deterioration, corrosion, and energy loss in solar PV systems, can be caused by environmental conditions such as high humidity, frequent rainfall, and temperature swings in tropical nations. Over the years, photovoltaic energy has been successfully developed to have low production costs and high efficiency. It has been the main reason that solar energy is one of the fastest-growing renewable energies in the world, with a generation of 821 TWh of electricity since 2021, repr [...]

This study analyzed the degree of loneliness, as well as acculturation and adaptation factors related to it among African migrants. The study sample consisted of 759 migrants (48.5% females) from four ethnocultural groups (Angolans, Cape Verdeans, Guineans, and Mozambicans) living in Portugal. Participants’ mean age was 37 years, and the mean length of sojourn in this country was 21 years. Participants completed self-reported questionnaires to evaluate social contacts, language proficiency, ethnic identity, perceiv [...]
