The quest to decarbonize the energy space to avert the negative climate change consequences calls for using low/zero-carbon energy conversion technologies in the energy generation space. The Organic Rankine Cycle is a low/zero-carbon energy conversion technology for recovering waste heat from low to medium-temperature heat sources and for biomass conversion. Therefore, this paper presents the thermodynamic optimization, with an artificial bee colony algorithm, of different ORC configurations, including simple organ [...]

Wheelchair basketball (WB) is a health and inclusion opportunity for people with disabilities. In the scientific literature, no evidence defines WB as a symmetrical or asymmetrical sport; however, it would be helpful to deepen this aspect because it could improve the quality of training programs and consequently speed up WB performance. In WB, the biomechanical role of the shoulders is crucial. Therefore, the symmetry index and the activation of the bilateral supraspinatus and biceps brachii muscles were investigat [...]

There are several definitions of sympathy, empathy, and compassion on the internet. I have chosen the above definitions to emphasize their salient differences, for the following reason: In medical school, in the early 1960s, we were taught not to sympathize with patients, but to empathize: By empathizing, one can retain some professional objectivity toward the patient, in order to be of some help. To sympathize, on the other hand, was to immerse oneself in the patient’s suffering and lose one’s professional per [...]

In this study, we report the complete chloroplast genome of Actinidia arguta var. purpurea. The chloroplast genome is 157,369 bp long as the circular (GC ratio is 37.22%). It has four subregions: a large single-copy (LSC) region of 88,609 bp, a small single-copy (SSC) region of 20,470 bp, and two inverted repeat regions (IRs) of 24,145 bp in each. The chloroplast genome of A. arguta var. purpurea contains a total of 113 unique genes, which are 79 protein-coding genes, 4 rRNA genes, and 3 [...]

Lesbian, gay, bisexual, transgender, and queer (LGBTQ+) elders are vulnerable to both the “usual” types of elder abuse (physical, sexual, emotional, and financial abuse, along with neglect), and with abuse that is specific to the context and history of LGBTQ+ elders. Training for adult protective services, long-term care ombudsmen, and other professionals who work with abused elders therefore should include information and skill-building in responding to this population. Research into effective training about LGBTQ [...]

Disasters such as the COVID-19 pandemic exact a toll on vulnerable populations in terms of morbidity and mortality, but they also provide opportunities for personal growth and development and demonstration of personal and collective resiliency. This inductive thematic analysis explores self-perceived negative and positive impacts of the COVID-19 pandemic on 2994 Canadians aged 55+. Data derive from response to two open-ended questions included in a national online survey (View Survey (sfu.ca)) conducted between Aug [...]

Core sediment (sapropel) samples were collected from Lake Okunozero, the Republic of Karelia, Russia, to assess the distribution of heavy metals and their main fractions, probable sources of pollution, and potential ecological and toxicological risks for the water body. Heavy metal concentrations were measured by the mass spectrometry method using an XSeries-2 ICP-MS. The sequential extraction of heavy metals from sapropel samples was performed using the scheme of Tessier. According to the Russian Interstate Standa [...]

Covid-19 pandemic has been infecting a substantial portion of the world population, thereby revealing quality deficits in health care in the majority of the countries around the globe. Severe illness and mortality from Covid-19 infection are present predominantly in minorities; especially they are more frequent in geriatric patients. Unfortunately, our knowledge is limited about what accounts for the variability in immune response from one person to another. This question is far from being merely academic, and find [...]

We present a case of a 74-year-old woman with deep intracerebral hemorrhage (ICH), probable cerebral amyloid angiopathy (CAA), and probable antiphospholipid syndrome (APS). Due to the high hemorrhagic risk, it was decided not to use anticoagulants. In a period of three months, she had two separate cerebral ischemic events and died of stroke-related complications. The use of oral anticoagulation (OAC) in this patient is neither supported nor contra-indicated by current literature, even though past medical history su [...]
