Bone cement is commonly utilized to secure prosthetic joints in the body because of its robust fixation, stability, biocompatibility, and immediate load-bearing capability. However, issues such as loosening, leakage, and insufficient bioactivity can lead to its failure. Therefore, improving its mechanical, physical, and biological properties is crucial for enhancing its efficiency.

However, the pandemic has also highlighted the harms to gig workers-who are exposed either to income loss, or to infection while carrying out essential work, but excluded from labour protections. We examine the COVID-19 policies of 191 platforms in 43 countries to understand how the crisis has shifted the conventions of the gig economy.

Brain tumors are considered to be a leading cause of cancer death among young people. Early diagnosis is thus essential for treatment. The brain segmentation process is still challenging due to complexity and variation of the tumor structure, intensity similarity between tumor tissues and normal brain tissues.

The aging population is growing increasingly more diverse, with one in four older adults from an ethnic minority group by 2050, while the nursing force will largely remain members of a single race White population. The purpose of this review is to appraise the state of nursing knowledge in relationship to meeting the needs of elders in unique racial/ethnic groups using two approaches: evaluating the efficacy of current knowledge and evaluating the state of nursing knowledge about ethnocultural gerontological nursing based on an integrative review of nursing literature. Thirty-four articles were reviewed.

View Article and Find Full Text PDFAs ethnic diversity increases in the United States with the anticipated increase in dementia, it is critical to understand the implications of dementia and culturally appropriate communication for ethnic minority older adults with dementia. Utilizing the Ethno-Cultural Gerontological Nursing model and the Progressively Lowered Stress Threshold model, this article describes the relationship between nursing assistants' communication style and behavioral symptoms of dementia, focused on Korean American older adults with dementia residing in nursing homes. The discussion includes reviewing currently available studies, nursing implications, and suggestions for future studies.

The proposed clustering algorithm, which is a RAdius based Clustering ALgorithm (RACAL), uses a distance based principle to map the distributions of the data by utilising the premise that clusters are determined by a distance parameter, without having to specify the number of clusters. Additionally, the proposed clustering algorithm is enhanced with a partial supervision strategy and it is demonstrated that it is able to segment blood vessels of small diameters and low contrasts.

The ability of laboratories to recover this species may be dependent on the culture conditions and the media used. Three dogs living in the households of 2 of these 6 patients had C.
