Predicting the hydraulic conductivity of compacted soil barriers in landfills using machine learning techniques
No full textMachine learning models (MLMs) were developed to predict saturated hydraulic conductivity of compacted soil barriers and help to identify appropriate soils for the construction of landfill liners and covers. Data from hydraulic conductivity tests on compacted soil barriers were collected from the literature and compiled into a database for MLM construction. The database contains 329 records of hydraulic conductivity tests associated with 12 selected impact factors covering physical properties, compaction efforts, and hydration and mineralogy behaviors of compacted soil barriers. Three machine learning algorithms (random forest, gradient boosting decision tree, and neural network) were used to develop MLMs, and a statistical technique (multiple linear regression) was used to compare the precision of predictions with the MLMs. Results from this study showed that the random forest model provided the best prediction of the hydraulic conductivity of compacted soil barriers, with 100% of predicted hydraulic conductivity within 100-time differences to measured hydraulic conductivity and 93% within 10-time differences. Feature importance analysis showed that void ratio after compaction, fines content, specific gravity, degree of saturation after compaction, and plasticity index of soils are the top-five factors (in descending order) that influence the hydraulic conductivity of compacted soil barriers and are recommended for a precise prediction. Three predictive MLMs were created for industries as simple tools to screen the soils prior to the construction of compacted soil barriers in landfill liners and covers
Eating Disorders and Metabolic Diseases
No full textEating disorders are complex diseases with multifactorial causes. According to the and the , the major types of eating disorders include anorexia nervosa, bulimia nervosa, and binge eating disorder. The prevalence of eating disorders is alarmingly increasing globally. Moreover, the COVID-19 pandemic has led to more development and worsening of eating disorders. Patients with eating disorders exhibit high rates of psychiatric comorbidities and medical comorbidities such as obesity, diabetes, and metabolic syndrome. This paper aims to review and discuss the comorbidities of eating disorders with those metabolic diseases. Eating disorder treatment typically includes a combination of some or all approaches such as psychotherapy, nutrition education, and medications. Early detection and intervention are important for the treatment of eating disorders

No full textOrganisational Culture Research in Healthcare: A Big Data Bibliometric Study
No full textAcross international healthcare, organisational culture and work environment have become central to all patient safety. However, there is a lack of comprehensive overview to assess and track the evolution of the literature on organisational culture in healthcare. This study aims to describe the current situation and global trends in organisational culture research in healthcare. The methodology is based on bibliometric mapping using scientific visualisation software (CiteSpace and VOSviewer). The big data were collected from the Web of Science core citation database. After applying the search criteria, we retrieved 1559 publications, which have steadily increased over the last two decades. In addition, 92 countries and regions have published studies on organisational culture in healthcare. The United States has made significant contributions to this field. In particular, organisational culture occupies an important position in the quality management of different types of care and caregiving. At the same time, organisational culture in healthcare may be inadequately researched in terms of theoretical underpinnings, which in turn leads to a lack of widespread dissemination of practice, and research on organisational culture in healthcare through evidence-based medicine may remain a significant focus and hot topic throughout the research field in the coming years
