Mechanical Behavior of Lithium-Ion Battery Separators under Uniaxial and Biaxial Loading Conditions.

The mechanical integrity of two commercially available lithium-ion battery separators was investigated under uniaxial and biaxial loading conditions. Two dry-processed microporous films with polypropylene (PP)/polyethylene (PE)/polypropylene (PP) compositions were studied: Celgard H2010 Trilayer and Celgard Q20S1HX Ceramic-Coated Trilayer. The uniaxial tests were carried out along the machine direction (MD), transverse direction (TD), and diagonal direction (DD).

Elasto-Static Analysis of Composite Restorations in a Molar Tooth: A Meshless Approach.

Dental caries and dental restorations possess a long history and over the years, many materials and methods have been invented. In recent decades, modern techniques and materials have brought complexity to this issue, which has created the necessity to investigate more and more to achieve durability, consistency, proper mechanical properties, efficiency, beauty, good colour, and reduced costs and time. Combined with the recent advances in the medical field, mechanical engineering plays a significant role in this topic.

Maternal and postweaning probiotic administration alleviated footshock-induced anxiety in both sexes of adolescent Balb/c mice.

: Effects of maternal probiotics administered during pregnancy as well as consumption by offspring in the post-weaning period on anxiety behavior were examined.: In addition to anxiety levels measured by EPM and OFT, the expression level of the hippocampal genes, and serum sex hormones in male and female mice that received foot shock stress were assayed in the pubertal period.: The results of this study showed that consumption of probiotics in the foot shock-stressed offspring in both sexes could significantly increase the length of stay in the EPM open arm compared to the control group, however, the offspring of the probiotic-treated dam did not.

Applying Machine Learning for Intelligent Assessment of Wheelchair Cushions from Pressure Mapping Images.

Pressure ulcers are skin and underlying tissue injuries caused by the cells' lack of oxygen and nutrition due to blood flow obstruction from constant pressure on the skin. It is prevalent in people with motion disabilities, such as wheelchair users. For both prevention and healing, wheelchair users should occasionally change their sitting posture, use cushions that evenly distribute the pressure, or relieve pressure from the sensitive areas.

Troponin is a useful marker in clinical decision making in hospitalized patients with COVID-19 infections.

Background: COVID-19 was introduced by the World Health Organization (WHO) as a global pandemic. The disease manifestations ranges from a mild common cold to severe disease and death. It has a higher mortality rate in people with a history of comorbidities, including cardiovascular disease (CVD) and can also contribute to cardiac injury.
