Bacteriological contamination of water sources, often due to improper handling of human waste, poses significant public health risks. This study investigates coliform bacteria contamination in water sources across the Fako Division of Cameroon. Twenty water samples were collected from various sources, including streams, community water, springs, boreholes, and wells, and analyzed for total coliforms using Violet-Red-Bile-Lactose (VRBL) Agar. Additionally, 352 household questionnaires were administered in four towns [...]

Background: The 2018 Alzheimer's Disease Facts and Figures special report includes two new guidelines for measuring dementia symptoms. The first requires that a biomarker (biological factor) be added to a doctor's clinical judgment of the cause of symptoms when determining whether dementia is present. The second involves identifying four stages of dementia: normal cognition, preclinical, MCI and dementia. Now only those with defining brain pathologies and significant symptoms will be judged to be persons with stage [...]

Background: Fluorescence In Situ Hybridization (FISH) has become routine for bio-medical research and medical diagnosis, thereby offering a variety of probes and ready-to-use kits that fulfil requirements for many applications. However, conventional FISH relies on chemical and/or thermal denaturation to improve target accessibility and uses huge amounts of DNA that needs to be bonded to the target site. COMBinatorial Oligo-nucleotide FISH (COMBO-FISH) offers possibilities to circumvent these shortcomings. Methods: [...]

Performance evaluations of wood and other lignocellulosic-based composites involve complex scenarios of several factors such as material heterogeneity and geometry that often leads to complicated, expensive, and time-consuming experimental procedures. Hence, the application of computational modeling and simulation is desirable to mitigate these biocomposites’ performance testing challenges. This review paper, therefore, presents an outlook on the finite element method (FEM) application in probing performance charac [...]

This research review sought to examine the patterns of engagement in advance care planning (ACP) and utilization of end-of-life (EoL) care treatment services including, but not limited to hospice care, in distinct older Asian American ethnic groups. The review of existing research suggested evidence that empirical studies about different older subpopulations of Asian Americans remains scarce. This research analysed 30 small-scale studies on older Asian Americans’ attitudes and engagement in EoL care planning. The r [...]

Since Charcot [1], researchers and theorists have associated hypnotic responsiveness with dissociation. However, contemporary researchers have typically not documented impressive or statistically significant correlations between the most commonly used measure of dissociation, the Dissociative Experiences Scale-II [2, 3] and hypnotic responsiveness. We examined the ability of two measures of non-pathological dissociation, which have received scant attention in the hypnosis literature, the Wessex Dissociation Scale ( [...]

Energy storage devices (ESD) including batteries, and supercapacitors are becoming progressively imperative in the transition to a renewable energy future, as they enable the integration of intermittent renewable sources into the grid and provide backup power during outages. There are already reviews available on various energy storage materials and systems. However, the challenges in the choice of suitable materials and fabrication technology are yet to establish for the commercialization of affordable and efficie [...]

The complete spectrum of neuropsychiatric effects of SARS-CoV-2 acute respiratory distress syndrome has yet to be fully appreciated, particularly in intubated patients. Manifestations including delirium and catatonia need to be considered in intubated COVID-19 patients. Medications known to exhibit neuroprotective effects, like valproate, can assist in agitation related to sedative withdrawal during extubation. This case series reports on the management of agitation, delirium, and catatonia in COVID-19 patients dur [...]

This paper investigates the composition, properties and reactivity of a red mud waste generated in Saudi Arabia with a view to find alternative materials to replace construction binders of high environmental impact. The phase transformation triggered by the sintering of the RM up to 1000°C is determined with thermal and X-Ray Diffraction analyses. Reactivity is investigated with chemical and physical methods including the Chapelle test, setting times, mechanical index and microscopy. The RM is clearly pozzol [...]

Background: Adult learners often engage in formal education because they want to create changes in their lives and are determined to succeed in their chosen field. However, they also come with emotional "baggage" of early educational experiences, frequently have to deal with a multitude of competing demands, have financial strain, may face a lack of support, illness and/or injury. In addition, they are often dealing with the challenges of unfamiliar academic work, competing deadlines and initially lack basic academ [...]
