The relevance of studying the cognitive and behavioral dynamics of psychopathy lies in its importance for improving diagnosis, therapeutic interventions, and reducing crime, thereby contributing to public safety. This study aimed to investigate how cognitive and behavioral mechanisms influence psychopathy. A combination of methods was employed, including the Levenson Self-Report Psychopathy Scale, semi-structured interviews, and the analysis of non-verbal reactions. The sample consisted of eight participants (four [...]

Aging models are important input into wind farm maintenance and financial viability models. Aging of wind turbines depends on many factors, including both ambient and usage conditions. This paper presents a virtual age based maintenance model for wind turbines considering the effect of wind speed and ambient air temperature on turbine aging. Two maintenance thresholds (i.e., corrective threshold and preventive threshold) and three repair actions (i.e., unscheduled corrective, scheduled corrective and preventive act [...]

The use of Pd-Cu bimetallic catalysts in the reduction of aqueous nitrate ions by hydrogen was studied. The catalysts were supported on multi-walled carbon nanotubes (MWCNTs), activated carbon (AC), and Titania, and the influence of the support on the nitrate reduction activity in water was then investigated. The catalysts were characterized before and after use by FT-IR, XRD, SEM, EDX, and Laser Granulometry. It was found that the surface characteristics of the support have an influence on the catalyst activity, w [...]

Background: Given the stigma and fear associated with Alzheimer’s disease (AD), combined with the progressive nature of the disease, the diagnosis of AD or mild cognitive impairment (MCI) is often very difficult; yet, there may still be ways to experience some positive outcomes following diagnosis. We aim to assess the psychological impact of a diagnosis of MCI or early dementia on positive well-being. Methods: Individuals with a diagnosis of MCI or AD were mailed surveys with the Silver-Lining Questionnaire. Resul [...]

Many multinational retail companies are exposed to financial risk related to climate change. Carbon management is important in keeping global temperature increases below 1.5°C to prevent the exacerbated impacts of climate change. Auchan Retail in Auchan Holding provides a good example of carbon management in the retail sector. Auchan Retail's major emissions are the indirect emissions throughout their value chain (scope 3 emissions). The total estimated emission of scopes 1, 2 and 3 are 37,822,573.9 t CO2e. [...]

Islet cell transplantation is a developing treatment for patients suffering from severe Type-1 diabetes. The long-term insulin independence after islet cell transplantation has been difficult to achieve, and this has been linked to several factors. One of the major cause of poor long-term outcome is inflammation surrounding the islets. Inflammation in islets is caused at several stages, donor induced, during organ preservation, islet isolation stress, peri-transplant inflammation or instant blood mediated inflammat [...]

Pediatric brain tumors account for approximately 25% of all cancers in children and are currently the leading cause of cancer-related deaths in the pediatric population with an estimated incidence of 5.14 cases per 100,000 person years [1]. Up to 10-15% of all pediatric brain tumors arise in the brainstem, with the majority of these classified as the diffuse intrinsic pontine glioma (DIPG) subtype [2]. The outcome of children with DIPG remains dismal with a median survival of <1 year. Owing to the unique locatio [...]

Background: The leaves of Mitragyna speciosa (kratom), a tropical tree that is indigenous to Southeast Asia, have been used traditionally to increase stamina, as a digestive aid, and as an analgesic. Kratom use is now increasingly popular in the rest of the world because of easy availability through the Internet and real, or perceived, views of efficacy and safety. Methods: PubMed and MedLine searches were conducted of published articles available in English. Results: Mitragynine and 7-hydroxymitragynine are the pr [...]

Renal cysts are present in a wide variety of hereditary renal diseases in children. The term polycystic kidney disease (PKD) refers to two specific hereditary diseases, distinguished by the usual age of onset and genetic cause: autosomal recessive polycystic kidney disease/congenital hepatic fibrosis (ARPKD/CHF, MIM *606702) and autosomal dominant polycystic disease (ADPKD-OMIM *601313 and OMIM *173910). ARPKD/CHF is characterized by cystic dilations of the renal collecting ducts and developmental defects of biliar [...]
