Question: James Stuart was a specialist in the roles of what type of moderate-to-very-fast music typically used in comic opera?
Context: Deep cement mixing (DCM) is a civil engineering deep foundation technique where a binder material, typically cement, is injected into the ground for ground stabilization and land reclamation.  In ground stabilization applications it is typically used to obtain a better load bearing capability of the existing soil, e.g. in order to bear buildings and other structures.  In land reclamation applications it is typically used when cheaper techniques such as dredging or draining cannot be applied because of environmental concerns due to contaminated soil that these two techniques would release.  The expansion of the Hong Kong International Airport and Tokyo's Haneda Airport are examples of this. James F. Stuart (23 December 1928, Baton Rouge, Louisiana — 7 March 2005) was an American opera director and operatic tenor.  He began his career performing and touring with Dorothy Raedler’s American Savoyards.  He became a specialist in the patter roles of Gilbert and Sullivan, including Sir Joseph Porter, K.C.B. in "H.M.S. Pinafore", Ko-Ko in "The Mikado", and Reginald Bunthorne in "Patience" among others.  In 1979 he founded the Ohio Light Opera in Wooster, Ohio, serving as the company's artistic director for two decades.  During his tenure there he also often worked as producer, stage director, translator, and performer.  He himself performed in fifty of the more than two hundred productions mounted by the company while he was director.  He also sang on twenty of the company's live operetta recordings, which encompassed works by both Americans and Europeans. James Stuart, 2nd Earl of Bute (before 1696 – 28 January 1723) was the son of James Stuart, 1st Earl of Bute and Agnes Mackenzie. Paracetamol, also known as acetaminophen or APAP, is a medication used to treat pain and fever.  It is typically used for mild to moderate pain.  The quality of the evidence regarding the use for fever relief in children is poor.  It is often sold in combination with other ingredients such as in many cold medications.  In combination with opioid pain medication, paracetamol is also used for more severe pain such as cancer pain and after surgery.  It is typically used either by mouth or rectally but is also available intravenously.  Effects last between two and four hours. Industrial enzymes are enzymes that are commercially used in a variety of industries such as pharmaceuticals, chemical production, biofuels, food & beverage, and consumer products.  Due to advancements in recent years, biocatalysis through isolated enzymes is considered more economical than use of whole cells.  Enzymes may be used as a unit operation within a process to generate a desired product, or may be the product of interest.  Industrial biological catalysis through enzymes has experienced rapid growth in recent years due to their ability to operate at mild conditions, and exceptional chiral and positional specificity, things that traditional chemical processes lack.  Isolated enzymes are typically used in hydrolytic and isomerization reactions.  Whole cells are typically used when a reaction requires a co-factor.  Although co-factors may be generated in vitro, it is typically more cost-effective to use metabolically active cells. The patter song is characterised by a moderately fast to very fast tempo with a rapid succession of rhythmic patterns in which each syllable of text corresponds to one note.  It is a staple of comic opera, especially Gilbert and Sullivan, but it has also been used in musicals and elsewhere. James Stuart, 4th Earl of Moray (c. 1611 – 4 March 1653) was the son of James Stuart, 3rd Earl of Moray and Lady Anne Gordon.

Pure pursuit is a type of pursuit curve used in aerial combat in which an aircraft pursues another aircraft by pointing its nose directly towards it.  This is in contrast with lead pursuit, in which the chasing aircraft points ahead of the aircraft it is following (typically used when attempting a gun attack) and lag pursuit, in which the chasing aircraft points behind the aircraft it is following (typically used when attempting a rear-aspect missile attack). Adoption studies are one of the classic tools of behavioral genetics.  These studies are used to estimate the degree to which a trait varies in response to environmental and genetic variation.  Adoption studies are typically used together with twin studies when estimating heritability.  There are two adoption study designs.  The adoptee's method investigates similarities between the adoptee and their biological and adoptive parents.  Similarity with the biological parent is expected to be heritable genetic effect, while similarity with the adoptive parent is associated with home-environment, called the shared environmental effect.  The familial method compares non-biological siblings who are reared in the same household.  Similarity to non-biological siblings raised in the same household is attributed to shared environment effect, as the siblings are biologically unrelated but share the home environment.  Variation that cannot be accounted by either genetics or home-environment is typically described as non-shared environment.  Adoption studies are one of the key tools in behavioral genetics and are typically used in combination with twin studies when making habitability estimates.
