An investigation has been made to study the off-centered stagnation flow of a couple stress fluid over a rotating disk. The model developed for the governing problem in the form of partial differential equations has been converted to ordinary differential equations with the use of suitable similarity transformation. The analytical approximation has been made with the most promising analytical approach, homotopy analysis method (HAM). The convergence region of the obtained solution is determined and plotted. The effects of couple stress and nondimensional parameters have been observed on the flows of couple stress fluid. Also comparison has been made with the Newtonian fluid as the special case of considered problem.

Iron is the most abundant transition metal in the brain and is essential for brain development and neuronal function; however, its abnormal accumulation is also implicated in various neurological disorders. The olfactory bulb (OB), an early target in neurodegenerative diseases, acts as a gateway for environmental toxins and contains diverse neuronal populations with distinct roles. This study explored the cell-specific vulnerability to iron in the OB using a mouse model of intranasal administration of ferric ammonium citrate (FAC).

Improving crop salinity management requires enhanced understanding of salinity responses of leaf and fine-root traits governing resource acquisition, ideally in relation to ion accumulation at intra- or inter-specific levels. We hypothesized that these responses are coupled towards integrated resource conservation for plants under prolonged salt treatment. We tested the hypothesis with a glasshouse experiment on saplings of six contrasting hybrids, subjected to either control or salt treatment (reverse osmosis water versus 3.

Marine heatwaves are increasingly common due to human-induced climate change. Under prolonged thermal stress on coral reefs, corals can undergo bleaching, leading to mass coral mortality and large-scale changes in benthic community composition. While coral mortality has clear, negative impacts on the body condition and populations of coral-dependent fish species, the mechanisms that drive these changes remain poorly resolved.

The long-term stability of Pt-based catalysts is critical to the reliability of proton exchange membrane fuel cells (PEMFCs), and receives constant attention. However, the current knowledge of Pt oxidation is restricted to unrealistic PEMFC cathode environment or operation, which questions its practical relevance. Herein, Pt oxidation is investigated directly in a PEMFC with stroboscopic operando high energy X-ray scattering.

Recurrent pregnancy loss (RPL), defined as two or more consecutive miscarriages before 20 weeks of gestation, affects 1-2% of couples worldwide. Pro-inflammatory cytokines, such as TNF-α, IL-1β and IL-6 play critical roles in early pregnancy, while anti-inflammatory cytokines like TGF-β and IL-10 promote immune tolerance to prevent harmful inflammatory responses that play important role in placental and fetal development. This aim of the study is to analyse the levels of inflammatory cytokines in blood serum from RPL patients and healthy women (control).
