Common-sense concepts

The sensing mechanisms of common humidity sensors related to conductive active materials, which can be simply attributed to the variations in resistivity due to the separation of conductive materials and variations in polymer permittivity, are generally plagued by drawbacks such as cumbersome fabrication processes, high cost and low performance. Herein, we prepared Zn/Cellulose filter paper (CFP)/Nanoscale carbon ink (NCI)/Cu structure humidity power generators (ZHGs) based on the power generation principle of typical zinc-air batteries, using active metals with strong conductivity as electrodes, and the redox reactions that took place in the zinc-air battery can convert the chemical energy in the electrode into a stable electrical energy...

INTRODUCTION: Several classifications of psychodermatology disorders have been proposed, with most of them based on two to four main disorder category groups. However, there is, to date, no classification that has resulted from a consensus established by psychodermatology experts. The DSM-5-TR (Diagnostic and statistical manual of mental disorders (5th ed.), Text Revision) and the ICD-11 (International classification of diseases (11th revision)) also do not provide a systematized approach of psychodermatology disorders...

INTRODUCTION: The presence of calling in medicine has been shown to be related to a preponderance of positive outcomes among medical students. However, only a few studies examined the antecedents of calling. Of this group, little is known about how a calling emerges and develops in a crisis situation. This study examines the processes underlying the emergence and development of calling when confronted with COVID-19. METHODS: Semi-structured interviews were conducted with medical students (N = 28) from China from February to March 2020...

Disinfection of water is essential to prevent the growth of pathogens, but at high levels, it can cause harm to human health. Therefore, accurate monitoring of disinfectant concentrations in water is essential to ensure safe drinking water. The use of multiple disinfectants at different stages in water treatment plants makes it necessary to also identify the type and concentrations of all of the disinfectant species present. Here, we demonstrate an effective approach to identify and quantify multiple disinfectants (using the example of free chlorine and potassium permanganate) in water using single-walled carbon nanotube (SWCNT)-based reagent-free chemiresistive sensing arrays...

In classical radar imaging, such as in Earth remote sensing, electromagnetic waves are usually assumed to propagate in free space. However, in numerous applications, such as ground penetrating radar or non-destructive testing, this assumption no longer holds. When there is a multi-material background, the subsurface image reconstruction becomes considerably more complex. Imaging can be performed in the spatial domain or, equivalently, in the wavenumber domain (k-space). In subsurface imaging, to date, objects with a non-planar surface are commonly reconstructed in the spatial domain, by the Backprojection algorithm combined with ray tracing, which is computationally demanding...

Two steps are able to lead to a significant decrease in the incidence of skin cancer overall and/or to its parallel and successful surgical treatment. The first step concerns its non-occurrence or less frequent clinical manifestation and is largely related to the modern concept known as prevention, but not the one mainly related to solar radiation, but: 1) informing patients about the possible contamination of certain drugs with carcinogens/nitrosamines/NDSRIs and 2) making clinicians aware of the modern concept of limited to completely eliminated intake of nitrosamines/NDSRIs in medications...

BACKGROUND: Cerebral palsy (CP) is one of the most common childhood disabilities, impacting many areas of a child's life. Increasingly, quality of life (QOL) measures are used to capture holistic wellbeing of children with CP. However most validated QOL measures for children are based on adult perspective only, with limited focus on child perspective. Conceptual differences between children's and adults' definitions of QOL may reflect different underlying QOL models which contribute to measurement score divergence...

Patients often ask, "why me?" but questions arise regarding what this statement means, how, when and why patients ask, how they answer and why. Interviews were conducted as part of several qualitative research studies exploring how patients view and cope with various conditions, including HIV, cancer, Huntington's disease and infertility. A secondary qualitative analysis was performed. Many patients ask, "why me?" but this statement emerges as having varying meanings, and entailing complex psychosocial processes...

Objective: In emergency medicine, airway management is a core skill that includes endotracheal intubation (ETI), a common technique that can result in ineffective ventilation and laryngotracheal injury if executed incorrectly. We present a method for automatically generating performance feedback during ETI simulator training, potentially augmenting training outcomes on robotic simulators. Method: Electret microphones recorded ultrasonic echoes pulsed through the complex geometry of a simulated airway during ETI performed on a full-size patient simulator...

The second external cause of death from unintentional injuries is falls in people over 60 and is a worldwide Public Health problem. Associated factors are identified early in Primary Health Care. Thus, we analyze professional narratives about older adults/old age and the organization of services in the presence of fall-inducing frailty. A structured narrative was applied under the following stages: understanding the context, setting/plot/character analysis, and interpretive synthesis. Data were collected from August to November 2022, distributing 21 health professionals in three Narrative Focus Groups...

AIM: To explain the process by which nurses' roles are negotiated in general practice. BACKGROUND: Primary care nurses do important work within a social model of health to meet the needs of the populations they serve. Latterly, in the face of increased demand and workforce shortages, they are also taking on more medical responsibilities through task-shifting. Despite the increased complexity of their professional role, little is known about the processes by which it is negotiated...

INTRODUCTION: The main aim was to gain insight into the experience of adult people with a diagnosis of at least 6-months of mild or moderate persistent asthma according to the Global Initiative for Asthma (GINA), and their emotions, beliefs, and expectations during the first wave of COVID-19. METHODS: Qualitative semi-structured interviews using the Interpretative Phenomenological Analysis (IPA) were carried out by phone involving 31 people (mean age=58.2; SD=16...

BACKGROUND: The advent of deep brain stimulation (DBS) of the subthalamic nucleus (STN) for Parkinson's disease 30 years ago has ushered a global breakthrough of DBS as a universal method for therapy and research in wide areas of neurology and psychiatry. The literature of the last three decades has described numerous concepts and practices of DBS, often branded as novelties or discoveries. However, reading the contemporary publications often elicits a sense of déjà vu in relation to several methods, attributes, and practices of DBS...

BACKGROUND: Smell loss is a common problem with an estimated 5% of the population having no functioning sense of smell. Viral causes of smell loss are the second most common cause and the coronavirus (COVID-19) pandemic is estimated to have caused 20,000 more people this year to have a lasting loss of smell. Isolation, depression, anxiety, and risk of danger from hazards such as toxic gas and spoiled food are all negative impacts. It also affects appetite with weight loss/gain in two-thirds of those affected...

While the role of autobiographical memory in self-representation is well established, the identity function of future thinking has received much less attention. Yet, most people commonly imagine future events that convey meaningful information about the person they wish or expect to become. In three experiments, we assessed the extent to which thinking about such self-defining future events influences the current content of self-representation (i.e., the working self-concept). Participants were asked to think about either a past or future self-defining event, or a control topic, before describing aspects of their identity in the form of "I am" statements (Experiments 1 and 3) or completing scales assessing self-related dimensions (Experiments 2 and 3)...

This quality improvement report details how Sultan Bin Abdulaziz Humanitarian City (The City), the largest rehabilitation facility within Middle East with a capacity of 511 beds and more than 20 nursing in-patient units improved the quality and patient safety culture in nursing services after successfully adopting and implementing the zero harm programme.In healthcare settings, the idea of zero harm including zero incidents, zero injuries and injury-free are commonly used to highlight the importance of patient safety...

BACKGROUND: Recent studies found that post-traumatic and dissociative symptoms are common in people with depressive symptoms. Although a trauma-related subtype of depression has been proposed, little is known about the persistence and clinical consequences of these symptoms. OBJECTIVE: This one-year follow-up study investigated the persistence and clinical consequences of post-traumatic and dissociative symptoms in people with depressive symptoms. METHODS: We analyzed longitudinal data from an international sample of people self-reporting depressive emotions ( N  = 152) (mean Patient Health Questionnaire-9 score = 17...

Across the millennia, and across a range of disciplines, there has been a widespread desire to connect, or translate between, the senses in a manner that is meaningful, rather than arbitrary. Early examples were often inspired by the vivid, yet mostly idiosyncratic, crossmodal matches expressed by synaesthetes, often exploited for aesthetic purposes by writers, artists, and composers. A separate approach comes from those academic commentators who have attempted to translate between structurally similar dimensions of perceptual experience (such as pitch and colour)...

Concrete is the most commonly used construction material nowadays. With emerging cutting-edge technologies such as nanomaterials (graphene, carbon nanotubes, etc.), advanced sensing (fiber optics, computer tomography, etc.), and artificial intelligence, concrete can now achieve self-sensing, self-healing, and ultrahigh performance. The concept and functions of smart concrete have thus been partially realized. However, due to the wider application location (coastal areas, cold regions, offshore, and deep ocean scenarios) and changing climate (temperature increase, more CO2 emissions, higher moisture, etc...

Nucleic acids are major targets for molecular sensing because of their wide involvement in biological functions. Determining their presence, movement, and binding specificity is thus well pursued. However, many current techniques are usually sophisticated, expensive, and often lack single-nucleotide resolution. In this paper, we report the force-induced visualization method that relies on the novel concept of mechanical force to determine the functional positions of nucleic acids with single-nucleotide resolution...
