Volumetric mass transfer coefficient (kLa) study with Pressure Swing Rotating Bubble Cap (PSRBC) sparger in a semi-batch bubble column

The present investigation is focused on evaluating the effect of sparger rotation on the mass transfer performance in terms of volumetric mass transfer coefficient ( k L a ) in a semi-batch Bubble Column equipped with a Pressure Swing Rotating Bubble Cap (PSRBC) sparger. In semi-...

Multimodal imaging reveals no evidence for magnetite-based magnetoreceptors in the mole-rat eye

Magnetoreception is widespread across animals, but its sensory mechanism remains unresolved. One leading hypothesis proposes that single-domain magnetite is coupled to mechanosensitive ion channels. In subterranean Ansell's mole-rats, such receptors have been proposed to reside i...

Estimating the undercount of intimate partner violence using multiple systems data

Abstract Reliable estimation of the underreported incidence of intimate partner violence (IPV) is essential to understand the true magnitude and public health burden. An integrated data system that combines multiple sources is commonly used to estimate such a hard-to-count popula...

Effects of Depression and Stress on Oral Self-care among Perinatal Women: A Longitudinal Study

Abstract Objectives: Perinatal oral health care is essential for the well-being of both women and fetal health. Oral health care involves both professional and self-care. Depression or stress during the perinatal phase can reduce oral hygiene maintenance and need intervention to...
