The author writes a genuine story using a narrative medicine writing style [1]. She relates how she applied mindfulness awareness and meditation practices to accompany her best friend, Abigail (Abigail is a pseudonym), who struggled through stages 3 and 4 breast cancer, including its noxious treatments and upsetting side effects. Clinical practice can be enhanced with narrative competence in that it helps the author recognize, interpret and be touched by patients’ stories, including all aspects of illness experienc [...]

The ever-growing urgency to combat climate change has led the civil construction industry to develop and adopt sustainable construction materials and methods. The so-called recycled concrete aggregate (RCA) emerges as an alternative to decrease the carbon footprint of new concrete construction, the disposal of waste concrete, and the use of non-renewable natural resources such as cement and aggregates. RCA can be produced from crushing waste concrete; yet challenges remain when using RCA in concrete especially its [...]

The human brain has been repeatedly shown to exhibit intercellular/somatic genomic variations at the chromosomal level, which are involved in the neuronal diversity in health and disease. Brain-specific chromosomal mosaicism (aneuploidy) and chromosome instability play a role in the normal and pathological neurodevelopment, neurodegeneration and aging of the central nervous system. Regardless of achievements in somatic cell (single-cell) genomics, there is still no consensus on the amounts of chromosomally abnormal [...]

Extreme temperatures, drought, and high soil salinity are some of the significant abiotic stresses that can severely impact crop yields, posing a threat to global food production. Comprehensive studies on model plant species are crucial for understanding their biochemical, physiological, and molecular responses to abiotic stresses. Identifying stress response mechanisms and potential targets can aid in developing stress-tolerant crop varieties. Additionally, elucidating the functions of reactive oxygen species is e [...]

Oil and gas wellbores that are drilled into the earth’s crust need to be plugged and abandoned, to restore the geological seals once they are no longer producing. The main aim of Plugging and abandonment (P&A) is to ensure that there is no leakage of hydrocarbons into the environment. Since offshore P&A is challenging due to subsurface temperature and pressure conditions, testing zeolite as an additive for improvement of cement properties is an intriguing research topic. This initial research aims to [...]

Visual external costs are significant elements in the cost-benefit analysis of wind farm locations. This has been demonstrated well in the literature. However, in the assessment of the visual costs, a large share of the earlier studies used no or only simplistic visualizations of the visual impacts at stake. The cost estimates thus rely on the respondents’ ability to imagine the visual impacts associated with wind turbines of different sizes and at different locations. This has been argued to potentially reduce the [...]

The kinetics of dearomatization of a kerosene fraction processed using a zeolite catalyst (0.9 HZSM-5) at different temperatures (160-200°C), the molar ratio between the aromatic hydrocarbons present in the kerosene fraction and n-decene (1:(0.5-4)), and the reaction time (1-3 h) were studied. Based on the obtained data, a kinetic model for kerosene dearomatization is proposed. It is assumed that the single-center Riedel mechanism is followed. The stage associated with the interaction between n-decene adsorbed on t [...]

(1) Background: Endoscopy has become the primary diagnostic and treatment technique for non-variceal upper gastrointestinal bleeding. Despite advancements in therapeutic methods and instrumentation, endoscopic hemostatic failure occurs in 10% of patients. This study aimed to analyze endoscopic findings in patients with failed hemostasis and to elucidate strategies for endoscopists and gastroenterologists to facilitate improved treatment outcomes. (2) Methods: A total of 128 patients received hemostatic treatment fo [...]

In advanced heart failure, orthotopic heart transplantation (OHT) remains the standard for definitive treatment. Patients with heart failure and concomitant pulmonary hypertension (PH) represent a challenging subgroup, with poor outcomes following OHT. Recently, Mechanical Circulatory Support (MCS) devices have been utilized as a bridge to OHT for these patients. Patients with MCS devices who underwent OHT were evaluated at a single center. Patients were stratified into three groups, depending on baseline pulmonary [...]

Spectrophotometry has been widely used to retrieve the dielectric function of a bulk iridium sample using an extended version of the Drude–Lorentz model. The parameters of the model are optimized using a spectral-projected-gradient-method-assisted acceptance-probability-controlled simulated annealing approach. Furthermore, optimized values of Drude parameters corresponding to the optical response of electrons and holes (scattering frequency of electrons, the ratio between scattering frequencies of holes and electro [...]
