Isotope

practical solution for waste management are still undergoing research. A possible leakage of the radioactive material could lead to a deadly disaster, releasing radioactive substances containing radioisotopes with long half-lives meaning that these isotopes stay in the atmosphere in some form or the other. These radiations can have a lasting effect on human life. There are two ways in which radioactive material harms the human body, it either kills cells in your body directly or it can cause…

What is the most important element of an engineer’s job? Speed or safety? There is no doubt that most engineers choose the public’s safety as their first priority instead of speed, for even a small difference between draft and reality can lead to engineering disaster. For some engineers who hold the speed as the highest goal, they had left several sever disasters caused by flaws in their engineering design; from their unforgettable experience, engineers put more thought in to the design before…

engineers developed countless designs and theories, however the final design was a true masterpiece of engineering. Unlike the Hydrogen bomb, which uses nuclear fusion, the Atomic bomb uses nuclear fission. According to The Atomic Heritage Foundation“The isotopes uranium-235 and plutonium-239 were selected by the atomic scientists because they readily undergo fission … When a uranium-235 atom absorbs a neutron and fissions into two new atoms, it releases three new neutrons and some binding…

these tools, several human bones, and teeth were also found. Chris Lepre, geologist, dated the artifacts by the layer of ash it was found in. The volcanic ash below the below the tool site set a “floor” on the site’s age. Based on the ratio of argon isotopes in the ash, Lepre could date the site to be 3.3 million years old. These findings can conclude that humans existed during that time, and were already becoming…

The plane that dropped the bomb is known as the Enola Gay, flown by Colonel Paul Tibbets. The bomb was ten feet and called the "Little Boy” it was created using uranium-235, a radioactive isotope of uranium. “Within three miles of the explosion, 60,000 of the 90,000 buildings were demolished” . The city was completely destroyed and full of rubble. “Hiroshima 's population has been estimated at 350,000; approximately 70,000 died immediately…

Iran nuclear framework deal How did Iran come to be? Iran is known officially as The Islamic republic of Iran. Is one of the world’s oldest civilisation dated between 3800 to 3200 BC. Home to 78 million people Iran has the second largest population in Middle East after Egypt. Comprised of multiple ethnic and religious groups and has Farsi as its official language. As of 2015 Iran is under a distinctive political system feeding back to 1979 constitution which blends religion and democracy with a…

Medical Stem Cell Usage Stem cell research and therapies have the ability to perform medical miracles. There are ethical and legal justification concerns surrounding the topic that are holding back huge advances in therapeutic studies and cures to diseases. Lifting certain restrictions on stem cell therapies and research could provide new ways and opportunities to save lives. Stem cell research should be continued further and given more legal wiggle room due to it’s enormous medical…

Studying plants alongside her lab partner Bill Hagopian, acclaimed geobiologist and geochemist Hope Jahren is known for her…

excepted one. The colder the atoms are the slower they move and the slower they decay. The second part is the smaller DNA fragments show to remain more connected. The reasoning is that there is less opportunity for the gens to contain an unstable isotope. That is why the results show that the small base pairs in colder environments such as the Greenlandic ice cores. These conclusions make sense and have…

In the Momona Ethiopian Journal Of Science, in an article titled “Investigating the Relationship between Team Cohesion and Self-Presentation among Different Competitive Team Sports of Ethiopian Universities”, T.A. Haddera (2016) was looking at cohesiveness within a team dynamic, “because it’s not only associated with group level outcomes such as performance but also with individual outcomes.” Again, this reinstates that there is a paradoxical nature to team sports in that you have individuals…
