Sporadic use of the term for some of the subject matter occurred subsequently, such as the use by Étienne Serres in 1838 to describe the natural history, or paleontology, of man, based on comparative anatomy, and the creation of a chair in anthropology and ethnography in 1850 at the National Museum of Natural History (France) by Jean Louis Armand de Quatrefages de Bréau. Various short-lived organizations of anthropologists had already been formed. The Société Ethnologique de Paris, the first to use Ethnology, was formed in 1839. Its members were primarily anti-slavery activists. When slavery was abolished in France in 1848 the Société was abandoned.
Who used the term anthropology to describe the natural history of man?
A: Étienne Serres

Theoretical obligations between a samurai and his lord (usually a daimyo) increased from the Genpei era to the Edo era. They were strongly emphasized by the teachings of Confucius and Mencius (ca 550 BC), which were required reading for the educated samurai class. Bushido was formalized by several influential leaders and families before the Edo Period. Bushido was an ideal, and it remained fairly uniform from the 13th century to the 19th century — the ideals of Bushido transcended social class, time and geographic location of the warrior class.
When was Bushido formalized?
A: before the Edo Period

 Capacitors deviate from the ideal capacitor equation in a number of ways. Some of these, such as leakage current and parasitic effects are linear, or can be assumed to be linear, and can be dealt with by adding virtual components to the equivalent circuit of the capacitor. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effect is non-linear and normal (i.e., linear) network analysis cannot be used, the effect must be dealt with separately. There is yet another group, which may be linear but invalidate the assumption in the analysis that capacitance is a constant. Such an example is temperature dependence. Finally, combined parasitic effects such as inherent inductance, resistance, or dielectric losses can exhibit non-uniform behavior at variable frequencies of operation.
Upon dealing with leakage current and parasitic effects in a realistic model of a capacitor, what sort of methods can then be applied?
A: The usual methods of network analysis

Seeking national reconciliation between revolutionaries and Catholics, the Concordat of 1801 was signed on 15 July 1801 between Napoleon and Pope Pius VII. It solidified the Roman Catholic Church as the majority church of France and brought back most of its civil status. The hostility of devout Catholics against the state had now largely been resolved. It did not restore the vast church lands and endowments that had been seized during the revolution and sold off. As a part of the Concordat, he presented another set of laws called the Organic Articles.
Along with Napoleon, who signed the Concordat of 1801?
A:
Pope Pius VII
