However, since " bronze " is a somewhat imprecise term, and historical pieces have variable compositions, in particular with an unclear boundary with brass, modern museum and scholarly descriptions of older objects increasingly use the more cautious and inclusive term " copper alloy " instead.

However, there is debate ongoing between groups that believe the evidence indicates substantial extinction of these species at the K – T boundary, and those who believe the evidence supports multiple extinctions and expansions through the boundary.

However, current research cannot ascertain whether the extinctions occurred prior to or during the boundary interval itself.

However, the use of data from coral fossils to support K – Pg extinction and subsequent Paleocene recovery must be weighed against the changes that occurred in coral ecosystems through the K – T boundary.

However, an open disk is not compact, because a sequence of points can tend to the boundary without getting arbitrarily close to any point in the interior.

However, the treatment of boundary conditions in these calculations has led to some controversy.

However no part of the shared boundary was afterwards demarcated.

However, near a refractive boundary ( say a nucleus within the cytoplasm ), the difference between the ordinary and the extraordinary beam will generate a relief in the image.

However, the McMahon Line lay south of the boundary India claims.

However, if the angle of incidence is greater ( i. e. the ray is closer to being parallel to the boundary ) than the critical angle – the angle of incidence at which light is refracted such that it travels along the boundary – then the light will stop crossing the boundary altogether and instead be totally reflected back internally.

However, Babylonian techniques of observational measurements were in a rudimentary stage of evolution and it was probably beyond their capacity to define in a precise way the boundary lines between the zodiacal signs in the sky.

However to help to determine an interval in years across the BC / AD boundary, it is more convenient to use a slightly different convention that includes a year zero and to represent earlier years as negative numbers.

However, small clusters do not exhibit sharp first order phase transitions such as melting, and at the boundary it is not possible to completely categorize the cluster as a liquid or solid, since these concepts are ( without extra definitions ) only applicable to macroscopic systems.

However, Powell lost his seat in the election by 731 votes to the Social Democratic and Labour Party's Eddie McGrady, mainly due to demographic and boundary changes that resulted in there being many more Irish Nationalists in the constituency than before.

However, Clay's specific proposals for achieving a compromise, including his idea for Texas ' boundary, were not adopted in a single bill.

However, as the potential function grows fast near the boundary of the Mandelbrot set, it was necessary for the creator to let the landscape grow downwards, so that it looked as if the Mandelbrot set was a plateau atop a mountain with steep sides.

However, this visible difference is merely a consequence of a deeper distinction: a DCT implies different boundary conditions than the DFT or other related transforms.

However, as the spacecraft's dataprobes had failed upon atmospheric penetration, no data from within the Venusian boundary was retrieved from the mission.

However, the commission established by the 1920 treaty redrew the boundary.

However, in this case as elsewhere it was necessary to arrive at a single standard to be applied to all situations, representing an averaging of conditions, and thus to fix particular points in time which would be considered the dividing points between daytime and nighttime conditions.

However, a major factor in binding dirt is the attraction between surfaces that goes under the name of Van der Waal's forces.

However, there are relatively few such political constituencies, and, as has been pointed out, there is seldom a clear-cut distinction between the educational interests of one social class and those of another.

However, there is a crucial difference between the two histories.

However, Ancient Egyptian is highly divergent from Proto-Afroasiatic ( Trombetti 1905: 1 – 2 ), and considerable time must have elapsed in between them.

However, as has been pointed out by Alexis Manaster Ramer and Paul Sidwell ( 1997 ), Strahlenberg actually opposed the idea of a closer relationship between the languages which later became known as " Altaic "..

However Juhanen ( 1992 ) is skeptical about an affiliation of Japanese to Altaic languages, while Róna-Tas ( 1998: 77 ) remarked that a relationship between Altaic and Japanese, if it ever existed, must be more remote than the relationship of any two of the Indo-European languages.

However, when forced to choose between Poirot and his wife in that novel, he initially chooses to betray Poirot to the Big Four so that they would not torture and kill his wife.

However, the rail link between Abkhazia and Georgia proper has been closed for a number of years, forcing Armenia to receive rail cars laden with cargo only through the relatively expensive rail-ferry services operating between Georgian and other Black Sea ports.

However, physicists distinguish between atomic physics — which deals with the atom as a system consisting of a nucleus and electrons — and nuclear physics, which considers atomic nuclei alone.

However, there is no one-to-one correspondence between words in ASL and English, and the inflectional modulation of ASL signs — a dominant part of the grammar — is lost.

However, there is an interesting contrast between the belief that exposure of signs to a hearing infant will aid them in language development, whereas a deaf infant at times must show the inability to learn an oral language before they are taught sign language.

However, this did not explain similarities between different atoms, as expressed by the periodic table, such as the fact that helium ( 2 electrons ), neon ( 10 electrons ), and argon ( 18 electrons ) exhibit similar chemical behavior.

However, the book On the Sizes and Distances of the Sun and Moon, which has long been ascribed to Aristarchus, says that he calculated the distance to the sun to be between 18 and 20 times the distance to the Moon, whereas the true ratio is about 389. 174.

However, despite the fact that he never officially bore the name Octavianus, to save confusing the dead dictator with his heir, historians often refer to the new Caesar — between his adoption and his assumption, in 27 BC, of the name Augustus — as Octavian.

However, these claims were given up in about 1870 during the War of the Pacific between Chile, the allied Bolivia and Peru, in a diplomatic deal to keep Argentina out of the war.

However, it does seem clear that his first notable work, Summa Quoniam Homines, was completed somewhere between 1155 and 1165, with the most conclusive date being 1160, and likely was developed through his lectures at the school in Paris.

However, commonly there are delays in regulatory and legislative actions to limit the use of antibacterials, attributable partly to resistance against such regulation by industries using or selling antibacterials, and to the time required for research to test causal links between antibacterial use and resistance.
