This case report describes a 5-year-old child who sustained fatal craniocervical injuries as the result of an inflating automobile air bag. Although air bags have in general been shown to reduce the severity of injury to occupants of vehicles involved in front-end collisions, a growing number of incidents suggests that in some instances the air bag system itself may cause injuries, some of which can be serious or even fatal. Small children and infants in infant seats travelling in the front passenger seat appear to be particularly at risk. The increasing number of reports of air bag mediated injuries highlights the need for changes in both system design and possibly the threshold speed required for air bag deployment.

In Kemerovo Region (Kuzbass, Southwest Siberia), there is the largest coal basin in Russia and one of the largest in the world. Active moss biomonitoring was applied to assess the impact of potentially toxic elements on air pollution in five urban areas of the region. In each of the chosen urban regions, the moss bags were exposed in November and December of 2022 at locations with varying degrees of anthropogenic pressure.

Electrically rechargeable zinc-air batteries (ZABs) are emerging as promising energy storage devices in the post-lithium era, leveraging the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) at the air cathodes. Efficient bifunctional oxygen electrocatalysts, capable of catalyzing both the ORR and OER, are essential for the operation of rechargeable ZABs. Traditional Pt- and RuO/IrO-based catalysts are not ideal, as they lack sufficient bifunctional ORR and OER activity, exhibit limited long-term durability, require high overpotentials and are expensive.

Background: Giant hydronephrosis as an rare condition is often caused by chronic ureteral obstruction. Nephroplication is a crucial procedure to improve urinary drainage in the kidney-sparing surgery for patients with giant hydronephrosis. However, traditional nephroplication via suturing kidney has technical difficulty and many potential risks.

Landfilling is common in developing countries since it is the easiest and cheapest way of waste disposal, however, it leads to serious environmental problems such as soil, water, and air pollution. A landfill has a life span of fifteen years after which it is closed leaving the site unusable, as a result, effective methods are needed for restoring and reclaiming the closed landfill site for future use. Phytoremediation has emerged as a viable and environmentally friendly method, which uses green plants to remove pollutants from soil, air, and water.

Empirical studies worldwide show that warming has variable effects on plant litter decomposition, leaving the overall impact of climate change on decomposition uncertain. We conducted a meta-analysis of 109 experimental warming studies across seven continents, using natural and standardised plant material, to assess the overarching effect of warming on litter decomposition and identify potential moderating factors. We determined that at least 5.
