Shape memory polymers (SMPs) are highly attractive materials for medical devices. Specifically, SMP foams are currently being used as embolic devices in peripheral and cerebral vascular applications. To ensure the proper function and safety of these materials in their intended applications, it is important to understand how processing treatments, such as aging, sterilization, and foam composition can influence their degradation. Here, SMP foams were treated with industry relevant processing parameters, and the infl [...]

As the climate crisis has progressed, scientists have begun to ask, "How does a rapidly warming ecosystem impact human behavior?" As aggression scholars and non-professional environmentalists, it has become increasingly clear that the impact of the climate crisis, without intervention, will dramatically increase humans' exposure to risk factors known to cause aggressive and violent behavior. This article describes a model that explains the indirect and direct effects of the climate crisis on aggression and violence [...]

Children with inflammatory bowel disease (IBD) have a high prevalence of vitamin D insufficiency secondary to factors such as malabsorption and decreased intake. In recent years the benefits of optimal vitamin D status have been highlighted for their potential to improve the disease course and long-term outcomes in this population. Clinical benefits have been seen to bone health, the immune system, and gut health, with further improvements to disease and treatment outcomes. Recommendations for vitamin D treatment p [...]

As the older population increases, there is an increase in age-related chronic diseases, especially heart failure. It affects 25% of over 75-year-old outpatients and represents the leading cause of hospitalization and death in older people. This review aimed to point out the main characteristics concerning heart failure in older people, taking into account clinical symptoms, diagnosis, and treatment. An extensive search on heart failure was made on PubMed and Google, using the keywords older people, heart failure, [...]

The present report provides a phenomenological theory for monolayer graphene, in which two worlds, the quantum and the classical, meet and complete each other in the most natural manner. In the present report, electron mass-vortex representation is introduced, and the surface tension excitation states in the monolayer graphene are defined. The band-mass of the electrons at the Dirac’s point was calculated through the mathematical introduction of a mass-dispersion relation. As a consequence, the Dirac’s [...]

The demand for high energy density rechargeable batteries beyond lithium-ion batteries has increased for electric vehicles. In the present study, a novel high energy density rechargeable aqueous lithium battery was proposed. The battery was composed of a lithium metal anode, a lithium-stable non-aqueous electrolyte, a water-stable lithium-ion conducting solid electrolyte of Li1.4Al0.4Ge0.2Ti1.4(PO4)3-epoxy-TiO2 separator, and a hydroquinone sulfonic acid (HQS)/benzoquinone sulfonic acid (BQS) redox couple in an aqu [...]

The transport sector accounts for approximately 25% of CO2-emissions in the EU and Austria, primarily due to passenger car transport powered by fossil fuels. Replacing conventional cars with sustainable alternatives is crucial for reducing emissions, improving air quality, and mitigating climate change while decreasing vehicle kilometers driven. This study analyzes policy strategies for Austria’s road passenger transport sector up to 2050 to determine their potential for significant CO2 reduction. Four scenar [...]

This study examined the techno-economic specifications for a Waste-to-Suburban Cooking Energy critical infrastructure project in Southwestern Nigeria. Technological and project economic data for the W2E project were obtained from strategic sources and energy project foresight/analysis framework used. The results showed residential upgraded biogas-for-cooking demand of approximately 10,243 m3/month, and municipal solid waste (MSW) input of approximately 80 tonnes/month. The planned biogas plant had estimated costs o [...]

This study presents a mixed methods evaluation of a transdiagnostic Compassion Focused Therapy (CFT) group intervention, for adults with long-term health conditions (LTHCs). It aims to assess whether group completion was associated with improved outcomes in mood, overall well-being and the extent of LTHC interference in confidence for managing daily activities. Additionally, it examines the extent to which changes were related to processes targeted by CFT. The ‘Living Well with Illness’ group consisted of eleven we [...]

Background: Mild Cognitive Impairment [MCI] is a transition stage between normal aging and dementia. It seems to be useful to treat MCI before the onset of early dementia, though no pharmacological treatment is recommended [1]. These case studies aimed to assess the efficacy of long-term repetitive Transcranial Magnetic Stimulation [rTMS] treatment on cognition, and clinical changes, in elderly MCI patients. Methods: Three patients with MCI were treated by rTMS with different parameters of stimulation, targeting th [...]
