A device for studying fluid-induced cracks under mixed-mode loading conditions using x-ray tomography.

We introduce an innovative instrument designed to investigate fluid-induced fractures under mixed loading conditions, including uniaxial tension and shear stress, in gels and similar soft materials. Equipped with sensors for measuring force, torque, and fluid pressure, the device is tailored for compatibility with x-ray tomography scanners, enabling non-invasive 3D analysis of crack geometries. To showcase its capabilities, we conducted a study examining crack-front segmentation in a hydrogel subjected to air pressure and a combination of tension and shear stress.

Serum Lipid, Amino Acid and Acylcarnitine Profiles of Obese Cats Supplemented with Dietary Choline and Fed to Maintenance Energy Requirements.

Obesity is a health concern for domestic cats. Obesity and severe energy restriction predispose cats to feline hepatic lipidosis. As choline is linked to lipid metabolism, we hypothesized that dietary choline supplementation would assist in reducing hepatic fat through increased lipoprotein transport and fatty acid oxidation.

Examining the Relation Between Gender Nonconformity and Psychological Well-Being in Children: The Roles of Peers and Parents.

No study to date has simultaneously tested how poor peer relations, generic risk factors, and parental attitudes impact the behavioral and emotional challenges of children who vary in their gender expression. In a community sample, the present study investigated various hypothesized psychosocial and generic risk factors regarding the association between childhood gender nonconformity (GNC) and psychological well-being. Canadian parents/guardians reported on their children aged 6-12 years (N = 1719, 48.

Children's bias in appraisals of gender-variant peers.

Past research suggests that children have biased negative appraisals of gender-variant (GV) peers (i.e., peers who display behaviors/interests that do not align with gender stereotypes).

Body composition of medium to giant breed dogs with or without cranial cruciate ligament disease.

Objective: To describe the body composition of dogs with or without cranial cruciate ligament (CCL) disease.

Study Design: Cross-sectional.

Animals: Adult dogs in which CCL disease was diagnosed (n = 30) and adult dogs without clinical signs of orthopedic disease (n = 30).
