This paper examines the economic case for the UK to proceed urgently with the installation of thermal insulation and heat pumps in most UK buildings, in the context of the legal requirement to achieve net-zero carbon emissions by 2050. A recent study by the same authors assumed that such insulation and heat pumps would be in place, and showed how the whole of the UK’s energy demand could be met by low carbon electricity generation and appropriate storage. This paper extends the modelling to consider the risk that i [...]

Background: Learning and memory, unquestionably, are critical for many aspects of life, including acquisition and retention of educational material. The purpose of this brief narrative review is to provide a primer on empirical-based, learning and memory techniques. Methods: A narrative review approach is employed. Results: This review is structured by first discussing contextual factors that influence learning and memory, followed by addressing several specific techniques to help facilitate learning and memory ret [...]

Preoperative sensitization of the cardiac transplant recipient, defined as the presence of anti-Human Leukocyte Antigen (HLA) antibodies before transplant, represents a significant management challenge for physicians. Sensitization prolongs the pre-transplant wait time and is associated with postoperative transplant complications and death. It is critical that sensitized heart transplant candidates be identified and optimized before surgery. In this review, we describe the risk for sensitization, discuss the means [...]

Left ventricular noncompaction cardiomyopathy (LVNC) is a rare form of heritable cardiomyopathy with wide genotypic variability, numerous phenotypic variations, and a wide spectrum of clinical disease from asymptomatic to end stage heart failure. Here, we present a case of a 2-year-old boy who presented to their pediatrician with a cough as a first clinical sign of heart failure, rapidly progressing to severe heart failure. He was found to have mixed LVNC with a restrictive phenotype, a rare phenotype of this form [...]

The FRAXE section of the FMR2 gene, located on the X chromosome, contains varying numbers of trinucleotide repeats; boys with over 200 repeats tend to have mild cognitive impairments, though this is rare. Little is known, however, concerning the phenotypes of individuals with smaller numbers of repeats. Here we answer the research question as to whether the health of ancestors of boys from whom the relevant X chromosome was inherited differed in any way according to the number of FRAXE repeats. Numbers of FRAXE rep [...]

The process of light-induced C-H oxygenation is of high interest as it can be used for the construction of oxygenated compounds. Herein, we report a mild and general method for the efficient synthesis of aromatic ketones following the process of metal-free C-H oxygenation. With air as the oxidant, high functional tolerance was demonstrated, and the desired ketones were obtained in moderate to excellent yields at room temperature (25 oC). Mechanistic studies suggested that the oxidative transformation potentially oc [...]

The purpose of this paper is to demonstrate that the integration of dreamwork and Energy Psychology (EP) can enhance outcomes in the treatment of a range of psychological disorders. The therapeutic process often begins with a peeling away of emotional layers until underlying issues surface. When utilizing dreamwork, however, it is possible to begin at a deeper level. Because dreams address salient unresolved emotional conflicts, dreamwork can quickly bring into consciousness previously unconscious emotional issues [...]

Chronically low blood pressure in older adults is associated with significantly increased long-term risks of dementia and all-cause mortality risk. Yet low blood pressure is generally not treated until an individual begins to experience the acute symptoms arising from very low cerebral perfusion. However, these acute symptoms, such as dizziness, balance difficulty, syncope, increased fall occurrence, vision impairment, and nausea, begin to occur only at very low blood pressure levels, such that mean arterial pressu [...]

Biodiversity—the rich variety of life on Earth—is essential for ecosystem stability and resilience, which, in turn, supports human well-being. However, human activities, such as habitat destruction, pollution, overexploitation, and climate change, are placing unprecedented pressures on global biodiversity, emphasizing the need for urgent conservation measures. In response, biodiversity education and outreach initiatives have become pivotal in fostering conservation awareness and action. This paper critically evalua [...]

By the adoption of a drag-buoyancy equality model, analytical solutions were obtained for the drag coefficients (CD) of Taylor bubbles rising steadily in pipes. The obtained solutions were functions of the geometry of the Taylor bubble and the gas volume fraction. The solutions were applicable at a wide range of Capillary numbers. The solution was validated by comparison with experimental data of other investigators. All derived drag formulas were subject to the condition that Bond number >4, for air-water syste [...]
