Mass timber products (MTPs) are being adopted in new building constructions and remodels in the last three decades, credited to their renewable and low carbon footprint characteristics. However, there are no mass timber manufacturers currently existing in Atlantic Canada. Extended distances of transporting MTPs to this region from other Canadian provinces may sacrifice the environmental benefits of using MTPs. This study was aimed to understand, via conducting a cradle-to-gate life cycle assessment (LCA), the envir [...]

Esophageal cancer is a disease with difficult clinical management, and palliative therapy is the only predominant treatment. This retrospective study analyses the results of clinical management of elderly patients (>75 years of age) who were treated with esophageal stenting for malignant dysphagia due to primary esophageal cancer, including squamous cell carcinoma (SCC), esophageal adenocarcinoma (EAC), as well as secondary esophageal malignant strictures due to non-small cell lung cancer (NSCLC). Patients with [...]

This narrative review highlights recent advances and ongoing trials using nutrition approaches for healthy aging. Focus will be placed on nutrition therapies that target cognition (“the mind”) and mobility (“the muscle”), both critical components to maintaining a high quality of life for older adults. For “the mind,” two seemingly incongruent therapies are being investigated to improve cognition–the MIND diet (high in carbohydrates and anti-oxidant fruits and vegetables) and the ketogenic diet (low in carbohydrates [...]

Acute or persistent pain is a common occurrence and is often undertreated in older patients, especially those with an inability to communicate verbally (ICV). Regular comprehensive pain assessment, including self-rating and/or behavior scales, is critical but difficult to implement in routine clinical practice. The choice of the most appropriate scale for each patient is not easy, even for trained and skilled medical personnel. Indeed, the use of scales for short pain-behavior exposes to pain under-detection due to [...]

Biogas is a promising resource for the production of H2 since it liberates energy by recycling waste, along with the reduction of CO2. In this paper, the biogas dry reforming membrane reactor is proposed to produce H2 for use in fuel cells. Pd/Cu alloy membrane is used to enhance the performance of the biogas dry reforming reactor. This study aims at understanding the effect of operating parameters such as feed ratio of sweep gas, pressure in the reactor, and reaction temperature on the performance of the biogas dr [...]

In the last decade, development in nanotechnology has been used intensively. By studying nanotechnology and nanomaterials, we can generate excellent responses in healthcare related to neurological disorders. It also includes easy diagnosis of diseases in their early stages, delivery of genes, and many more. Neurological disorders are one of the most sensitive topics. Therefore, nanomaterials promise to treat neurological disorders as they are highly efficient. Nanomaterials will significantly expand our knowledge o [...]

As the 80 million “baby boomers” reach retirement, they bring their relaxed attitudes toward drug use to create a clinically significant population of geriatric drug abusers. Opioid use disorder (OUD) brings with it special considerations in the elderly population: age-related changes to drug disposition, brain changes in the elderly, polypharmacy, and the likelihood of comorbid conditions (such as cardiovascular or pulmonary diseases) and pain syndromes. Thirteen percent of patients in a New York city methadone cl [...]

The COVID-19 pandemic has drastically changed the lives of people, as well as the production and economic systems throughout the world. The flow of raw materials and products, the supply of labor and manpower, and the purchasing power have all been changed to the detriment of individual health and well-being. Such a situation requires placing even more emphasis on the search for virtuous agricultural systems compatible with the goals of economic and environmental development so clearly defined at the world level in [...]

In this study, uncertainties during the assessment of the electrochemical impedance spectrum of the polymer electrolyte fuel cell (PEFC) attributed to inductive artefacts at high frequencies and inductive loops at low frequencies as well as oxygen diffusion time constant are discussed. A validated impedance model represented as an equivalent electrical circuit of a PEFC allowed the simulation of the effect of inductive artefacts, inductive loops and oxygen diffusion time constant on electrochemical impedance spectr [...]

Rhodamine (RhB) adsorption was carried out on MCM-41 and MCM-41 calcined. The effect of parameters such as pH was investigated. The reusability potential of MCM-41 was also established and the mechanism of RhB adsorption was discussed. MCM-41 was synthesized and calcined, with all samples characterized by X-Ray Diffractometry, X-ray Fluorescence by Dispersive Energy, Infrared Spectroscopy, Scanning Electron Microscopy, and Thermogravimetric analysis. The results of the characterization techniques performed confirme [...]
