The Ratio of Isotope to Normal Carbon in Bone and Charcoal
- The specimens were found to be 17,500 to 18,300 years old by determining the ratio of isotope to normal carbon in bone and charcoal.
- Is it natural to use commas when mentioning the ratio of isotope to normal carbon in bone and charcoal? Or is it specific to newspaper articles?
- When I translate it to English, it becomes something like 'By determining the ratio of isotope to normal carbon in bone and charcoal, the specimens were found to be 17,500 to 18,300 years old.'

carbon「炭素」には質量数がそれぞれ12, 13, 14 の３種類があります。 このような同一元素でありながら，質量数の異なるものが複数存在する元素を同位体 isotope と言います。 an isotope of carbon といえば carbon-12, carbon-13, carbon-14 のいずれかを表します。 ここでは放射性同位体である carbon-14 を表していますが，特に12とか14というのは問題でないため，まず a type of carbon「炭素の一種」と言っておいて，単に a type「一つの型」だと不明瞭なので，an isotope of carbon と言い直しています。 an type of carbon, or an isotope of carbon というのを簡潔に，かつ明確にしたのが a type, or isotope, of carbon です。 a type of の部分にコンマにはさまれる形で挿入することになります。 ここでは an isotope of carbon は carbon-14 を表していますが，単に an isotope でこの14の方を表すわけではありません。

By determining the fraction of a type, or isotope, of carbon in bone fragments and charcoal, the specimens were found to be 17,500 to 18,300 years old.The authors say that the ages are more precise than previous efforts because a series of more than 40 radiocarbon-dated samples support the estimate.The work is reported in the Proceedings of the National Academy of Sciences.The Yuchanyan cave was the site where the oldest kernels of rice were found in 2005, and it is viewed as an important link between cave-dwelling hunter-gathere peoples the farmers that arose later in the basin of the nearby Yangtze River.The previous oldest -known example of pottery was found in Japan, dated to an age between 16,000 and 17,000 years ago, but debate has raged in the archaeological community as to whether pottery was first made in China or Japan. 最古の陶器が中国で発見された。中国湖南省の玉蟾岩（Yuchanyan：玉ヒキガエル岩）の洞窟の中で見つかった陶器の例は、科学者に知られている最古の例である。刻印の破片あるいは骨の破片および炭の中の同位元素の判定により、試料は１７５００から１８３００年たっていることが分かった。著者らは、この時代（１７５００～１８３００年前）は４０以上の時代が特定された一連の試料により立証された推定なので、以前の取組より正確であると述べた。その成果（業績）は全米自然科学協会誌に報告された。玉蟾岩の洞窟は２００５年に最古の米粒が発見された現場であり、そしてそれは狩猟採集民と揚子江近くの盆地に後に発生した農民を結びつける重要なものとみなされた。陶器の以前最古と知られていた例は日本で発見され、 １６０００および１７０００年前の間の年代と推定された。しかし、考古学界において、論争は陶器が最初に中国あるいは日本で造られたかどうかについて高まった。

Although the magnitude of the variations of carbon-14 is strongly attenuated through the carbon cycle after being produced by the GCRs in the atmosphere (Siegenthaler and Beer, 1988), carbon-14 in tree-rings preserve the information on the variations in solar cycles and the magnetic dipole polarity of the sun. Therefore, the variability of the “11-year” solar cycle in association with the century-scale variations of solar activity can be monitored to asses its influence on climate. The lengths of sunspot periods have been modulated by a few years since the 11-year sunspot cycle was firstly found by Schwabe (1843). The maximum range observed so far is ~ 9 to ~ 14 years, but most of the cycles fit in ~ 10–12 years with the overall average being 11 years. However, we have previously found a change in average cycle length during the Maunder Minimum ((Miyahara et al., 2004); see Supplementary Fig. S1). The sunspots were scarce through 1645–1715 AD due to the anomalous weakening of the magnetic activity at this time, yet the carbon-14 abundances show the appearance of significant cyclic changes in magnetic activity. The average length of the cycles through the 70 years was about 14 years with the 28-year period of magnetic polarity reversals. The relationship between the cycle length of the “11-year” variation in sunspots and its magnitude has been investigated in several papers (Clough, 1905, Solanki et al., 2002 and Rogers et al., 2006). A consistent feature is the inverse correlation between cycle amplitudes and cycle lengths that maybe related to the change of the meridional flows inside the convection zone of the sun (Hathaway et al., 2003).

The diffculties and disputes which attended the first revival of science have recurred in the present century in consequence of the growth of geology. It is in truth only the old question over again－precisely the same point of theology which is involved, although the difficulties which present themselves are fresh. The school books of the present day, while they teach the child that the earth moves, yet [they] assure him that it is a little less than six thousand years old and that it was made in six days. On the other hand, geologists of all religious creeds are agreed that the earth has existed for an immense series of years－to be [to be=it should be] counted by millions rather than by thousands:and that indubitably more than six days elapsed from its first creation to the appearance of man upon its surface. By this broad discrepancy between old and doctrine is the modern mind startled, as were the men of the sixteenth century [startled] when [they were] told that the earth moved.

Note that in the twenty-nine centuries between 1000 B.C. and 1900, life expectancy increased by almost thirty years, and in the seventy years between 1900 and it increased almost another twenty-four years. These striking increases are misleading, however, because the averages reflect to a very large extent reductions in infant mortality. The figures we have been discussing-the ones in the first row of the second section-are life expectancies at birth. The second row of this table shows the life expectancies at the age of sixty-five years. It can be seen that in 1970, the average sixty-five-year-old could expect to live about fifteen more years, to the age of about eighty-nine years longer than the average life expectancy of the newborn infant. That is, when you were born you could expect to live seventy-one years, and as you grew older and survived longer, you could expect to live longer. (See P＆L Close-up, Life Expectancy: How Long Is long?) お願いします。

Then, in the mid-nineteenth century, the world's population started to increase rapidly. In the 100 years between 1830 and 1930, the population of the world grew from 1 billion to 2 billion people. By 1960, just thirty years later, the world's population had hit 3 billion. Fifteen years later, the population reached 4 billion. Then, just eleven years later, there were 5 billion people on Earth. In 1999, we passed the 6 billion mark. Today, the world's population grows by 76 million people every year. By the year 2050, researchers predict that the population of the world will be 9.1 billion.

１．参議院選挙が７月10日行われる The Upper House election is held on July 10. ２．今回から18歳、19歳も投票する From this time on, the ages of 18 and 19 people can vote. ３．18歳での投票は早すぎるとずっと思っていた。 I thought all the time the vote at 18 years old was too early. ４．しかし、イギリスのEU離脱問題のお蔭で、考えが変わった。 But thanks to the issue of EU secession, I changed my thought. ５．イギリスで国民投票が行われ、離脱が決まった。 England held a referendum on the matter of EU secession and decided leave from EU. ６．18歳から24歳の若い人は、73%が残留支持だった。 73% of young people from 18 to 24 years old were remain supporter. ７．自分たちが投票に行かなくとも、残留に決まると思い、投票に行かなかった But many young people did not go for a vote. Because they thought even if they did not go to the vote, it was decided on remaining in any case. ８．若者たちは、「年寄り世代が、若者の将来を決めてしまった」と今になって怒っている They are now regret and angry. And they said, “An old generation has decided the future of the youth”. ９．18歳と言えば、20から30年後、中年の働き盛りである。 Speaking of 18 years old, 20 to 30 years later, they are a person who is in his or her prime. 10．他方、イギリスで65歳以上の人の60%が離脱に賛成だったという。 On the other hand, 60% of people 65 years or older were agreeable to the secession. 11．20から30年後、彼らの多くがこの世にいない But 20 to 30 years later, most of them will not be in the world anymore. 12．30年後の事を考えると、選挙権は18歳でいいかも知れない When I think about 30 years later, 18 years old may be enough for the right to vote. 以上です。回答者様の考えとは違うかも知れませんが、宜しくお願い致します。
