The interaction of catalyst particles with reducible support materials can drastically change their reactivity. On rutile TiO, processes like particle encapsulation (caused by the "strong metal-support interaction", SMSI) have long been known to depend on the initial reduction state of the oxide. Despite this knowledge, sample stoichiometry has rarely been controlled in a reproducible manner in the surface science literature.

A promising method for optimizing rubber processing in a short period of time is the use of simulation routines. However, process simulations have only recently enabled meaningful predictions of not only the part's state of cure but also its mechanical characteristics.

Methods: A prospective mixed-methods approach was utilized including chart review of infants who died in a regional NICU over a twenty-six-month period and surveys of their neonatologists, neonatal fellows, and nurses.
Results: 40 infants died during the study period and 120 staff surveys were completed.

Mushrooms containing amatoxins generate the highest number of fatal mycete poisonings on the planet. These toxins are produced not only by Amanita species, such as the well-known Amanita phalloides, but also by other genera, including Lepiota. In this work we report the treatment of a 51-year-old male patient weighing 79 kg who was referred to the hospital after 36 h of ingesting mushrooms.

One tool that can help providers identify when biases are impacting the clinical care they are providing and enable them to take corrective action in real time is the "Ladder of Inference" (LOI). The LOI is an instrument that elucidates the process by which we take in information about another person, filter that data through our own interests, needs, perspectives and biases, and then use it to draw conclusions about the individual.
