Coulomb's Law and Nuclear Stability
- Coulomb's law states that like charges repel and unlike charges attract.
- In nuclear chemistry, the stability of a nucleus relies on the balance between coulombic repulsion and short-range attraction.
- If the repulsion outweighs attraction, the nucleus disintegrates, emitting particles and/or radiation. If attractive forces prevail, the nucleus is stable.

From Coulomb's law we know that like charge repel and unlike charges attract one another. We would thus expect the proton to repel one another strongly, particularly when we consider how close they must be to each other.This indeed is so. However, in addition to the repulsion, there are also short-range attractions between proton and proton, proton and neutron, and neutron and neutron. The stability of any nucleus is determind by the difference coulombic repulsion and the short-range attraction. If repulsion outweighs attraction, the nucleus disintegrates,emitting particles and/or radiation. If attractive forces prevail, the nucleus is stable. 核化学に関する英文です。

「わたしたちはクーロンの法則によって、同じ電荷は反発し合い、異なる電荷は互いに引き合うということを知っている。そこで陽子同士も強く反発し合い、特に距離が近ければその反発の度合いも大きいだろうという予想がされる。実際そうである。しかしながら、反発する力だけでなく、陽子と陽子、陽子と中性子、あるいは中性子と中性子の間において、その距離が近ければ引き合う力も働く。原子核がどれくらい安定しているかは、クーロンの法則におけるような反作用と、近い距離における引力との相違によって決まる。もしも反発力が引力を上回れば、原子核は素粒子および（または）放射線を放出して崩壊する。もしも印訳が上回れば、その原子核は安定している」

The principal factor that determines whether a nucleus is stable is the neutron-to-proton ratio. For stable atoms of elements having low atomic number, the n/p value is close to 1. As the atomic number increases, the neutron-to-proton ratios of the stable nuclei become greater than 1. This deviation at higher atomic numbers arises because a larger number of neutrons is needed to counteract the strong repulsion among the protons and stabilize the nucleus. この英文を和訳してください。核化学に関する英文です。

It is salutary to realize the fundamental isolation of the individual mind. We have no certain knowledge of any consciousness but our own. We can only know the world through our own personality. Because the behaviour of others is similar to our own, we suppose that they are like us; it is a shock to discover that they are not. As i grow older I am more and more amazed to discover how great are the differences between one man and another. I am not far from believing that everyone is unique.

The organization was paying for computer projects at universities all over the USA. But Bob Taylor was not happy with the results. He went to see his boss, Charlie Herzfeld. Charlie, we have a problem, he said. What is that? Herzfeld asked. We are throwing money away, said Taylor. We are paying different people all over the USA to do exactly the same study. What is wrong with them ? shouted Herzfeld, who had a strong Austrian accent and scared many of the people who woreked for him. Dont not they go to meetings? We pay for them to go to meetings. Why do not they just tell each other what they are doing? No, Charlie, that is not the problems, explained Taylor. Of course our people talk to each other. The trouble is that their computers do not. Their computers do not talk? What do you mean? asked Herzfeld. Well, look at my office. I have got connections there to all of our biggest computers. But if I want to communicate with the people at Santa Monica, I have to sit down at one machine. And if I want to talk to the computer at Berkeley, I have to get up from that machine, go over and sit at another one, and use a completely diffrent computer language.

We cannot, we must not, refuse to protect the right of every American to vote in every election that he may desire to participate in.And we ought not, and we cannot, and we must not wait another eight months before we get a bill. We have already waited 100 years and more and the time for waiting is gone. So I ask you to join me in working long hours and nights and weekends, if necessary, to pass this bill. And I don't make that request lightly, for, from the window where I sit, with the problems of our country, I recognize that from outside this chamber is the outraged conscience of a nation, the grave concern of many nations and the harsh judgment of history on our acts.

Systems theory is a fascinating new discipline. By looking at each part of a system and determining the effect it has on other parts, a map of the process can be made. This analysis helps make it clear how changes in one part of the system affect other parts and the system as a whole. A common example now is the melting of ice in the Arctic. If the summer temperature stays under a particular point, the amount of melted ice stays small. However, if the average temperature of the air in the summer is too high, the system might enter a state where all the ice melts. This happens because of a feedback loop: since ice reflects a lot of sunlight away from the Arctic, if there is less ice than usual, then more water will absorb sunlight and warm up. With more warm water present, more ice melts, and more water gets warmed up; this cycle continues, and accelerates. Soon, there is no more ice left. As for the mercury cycle, the ocean methylation process is not completely understood, so we are not yet able to figure out how to prevent mercury from methylating and entering the food chain. Once the process is understood, we hope to be able to control the amount of methylation so as to protect our marine food supply.

From the time that life first appeared on Earth, species have gone extinct. Extinction is a natural part of evolution. Species that are best at adapting to their environment survive. Other species are unable to adapt quickly enough – so they die off. So, why do endangered species get so much attention today? One reason is much of the extinction happening these days is unnatural. The leading reason for a species to become endangered is loss of habitat. As humans cut down forests for farmland, expand cities, or pollute waterways, to name a few ways that habitat is destroyed, animals, plants, and insects find it harder and harder to survive. Thus, the effect of humans on the natural world is causing species to become endangered, and, ultimately, go extinct. Another leading reason for a species to become endangered is climate change. For example, the lizards in this article could probably adapt to a gradual change in temperature. However, the rapid change in the climate, and the consequent decrease in lizard birthrate, threaten to doom many lizard species. If human activity is a major reason for climate change, then it would seem that we are changing our world far too rapidly for species to naturally adapt. Humans are highly adaptable, but most species need a lot of time to get used to changing conditions.

英文を和訳していただけるかたのみで、 お願いできますでしょうか？ ３つの段落になっています。 どうぞよろしくお願いいたします But what else? You may think I have told you all you could possibly want to know. It isn’t so. SOUL MATE TWO, is the same length and just as detailed as soul mate one, it follows a similar pattern, if you loved this reading you will love Soul Mate Two. Astrology is a bit like archaeology in that each additional reading on the same subject we must dig into a deeper layer of the chart and more time and work is involved. SOUL MATE THREE, if you still want more, if your spirit still has a hunger to taste the romance in your future. If it wants to look again into the mirror of time. Then Soul Mate Three is the last of these readings, it will reveal anything that is not covered in soul mate one or two. I cannot tell more than that because I never know what it will show in your particular reading until I look at your own chart, Again it is deeply penetrating and more difficult to do, because each time we look we have to go deeper it take a bit longer. May they bring love light and enlightenment into your spirit.

I feel great energy coming from you. For a long time I have an idea to write a book together with someone from another culture, especially Japan, that I am crazy for Japan. We could write in distance, create a few characters some 4 probably, 2 would be you (if you agree) and me. So, I would write from my character and send to you, you would add something and send to me, and have a small book at the end. Is this a good idea? It is interesting for me to blend different cultures. It can be something like Haruki Murakami style. Please answer me in my mail address. @@@@@@@@@@@@@@@ Isn't it exciting? I cannot wait what you gonna answer me. Maybe we will become big and famous one day. Thank you. Bye
