Water immersion during labour and birth has become increasingly popular and widespread in many countries, in particular in midwifery-led care settings. Nevertheless, there is a dearth of quality data about waterbirth, with currently available findings mostly arising from observational studies and case series. The lack of high-quality evidence and the controversial results reported by different studies determined a "behavioral gap" without clearly objective, consistent indications allowing for a sound and evidence-based decision making process. Although water immersion in the first stage of labour is generally considered a safe and cost-effective method of pain management for women in labor, concerns still linger as to the safety of immersion during the second stage of labor and delivery, particularly in terms of neonatal risks and medico-legal implications.

Macroalgae widely distribute in intertidal zones, one of blue carbon organisms. However, the regulatory mechanisms of tide on the carbon sequestration of macroalgae are still unclear. This study explored the effects of desiccation-rewetting cycles induced by tide on dissolved organic carbon (DOC) release from Ulva pertusa, which is prevalent from high to low tidal zones.

Multifunctional coatings have great application value in the protection of Marine equipment, ships and ship facilities, but they still suffer from the disadvantages of high preparation cost and complicated synthesis methods. Herein, employing a simple method to synthesize black carbon nitride (BCN), as the filler in polydimethylsiloxane (PDMS) to construct BCN/PDMS composite coating with a multifunctional anti-corrosion/antifouling coating capable of photothermal self-healing property. Experimental results exhibit that the BCN/PDMS coating can still possesses excellent corrosion resistance after 28 d of immersion in the simulated seawater, and the impedance modulus still manages to reach 6.

To further elucidate the variations of secondary oxidation spontaneous combustion risk of lignite under different air flows and immersion time. Secondary oxidation experiments of short-term water-immersed coal and long-term water-immersed coal were conducted under four air flows. The results show that, the presence of a temperature inflection point during primary oxidation process, when coal temperature exceeds it, both the oxygen consumption rate and heat release intensity of long-term water-immersed coal are lower, furthermore, decrease in air flow leads to reduction in the temperature inflection point.

Article Synopsis
- Using alternating currents (AC) can effectively prevent the formation of mineral crystals on surfaces in contact with super-saturated fluids, such as heat exchangers and pipes.
- The study demonstrates that periodic charging and discharging of the electrical double layer (EDL) on titanium sheets in super-saturated CaCO solutions inhibits both crystal nucleation and growth due to enhanced ion migration.
- Operating at 4 V and frequencies between 0.1-10 Hz results in over 96% reduction in turbidity and over 92% reduction in calcium carbonate coverage, showcasing a promising method for controlling mineral scaling in various industrial applications.
