what led to the decline of the Roman Empire?" The fall of the Western Roman Empire was caused by three of the many reasons: internal decay‚ lack of money‚ and invading tribes. First‚ one of the reasons that led to the decline of the Western Roman Empire was internal decay. It has been said that the Roman’s military crisis was a huge factor in this internal decay. According to Indro Montanelli‚ "the military crisis was the result of shortage of children." The children in Rome were not old enough

Both the dental examination and the periodontal exam instruments will be used to score caries and tooth decay. For proper visibility‚ natural light and a hand held flash light will be used. Cotton pads will be used to dry the mouth and mouthwash and bottled water will be provided with cups to rinse after the examinations. The dental examination form is used to mark all teeth with tooth decay or cavities. Every dental examination will vary and can last from 2 minutes to 15 minutes depending on the

Write about the ways Tennyson tells the story in ‘Tithonus’ Tennyson tells the story of Tithonus with very mixed emotions. One minute he is in the depths of despair‚ and next confessing his desire for his lover. In Tithonus‚ a variety of techniques are used to show the narrator’s thoughts and feelings. One of the techniques involved is repetition. ‘Ay me! ay me!’ This repetition hints at how strong his despair is‚ slowly decaying but not dying as an immortal. The exclamation marks show that

Abandoned former factories‚ shops and buildings start to decay and become derelict and useless due to disuse and no maintenance. This process of decentralisation and urban decay occurred in Pyrmont-Ultimo in the 1950s as industry started to move out into the suburbs which caused a major decline in population. By the 1990s Pyrmont-Ultimo ’s population had decreased to

in the form of radiation‚ until a stable nucleus is produced; this is called the radioactive decay. Four isotopes as well as their uses are mentioned subsequently. Americium: Americium is a silvery metal‚ which corrodes slowly in air and is soluble in acid. It has the isotopes: Am-243‚ Am-242 and Am-241‚ with a half-life of 432 years‚ which was the first isotope to be isolated. The isotope Am-241 decays by emitting alpha particles and intense gamma radiation to become neptunium-237. Americium

which is relatively weak on the subatomic scale‚ and are therefore able to travel great distances through matter without being affected by it. How are neutrinos being created? Neutrinos are created as a result of certain types of radioactive decay‚ ornuclear reactions such as those that take place in the Sun‚ in nuclear reactors‚ or when cosmic rays hit atoms. Most neutrinos passing through the Earth emanate from the Sun. Types of Neutrino i. electron neutrinos ii. muon neutrinos

use of multiple tones‚ diction‚ imagery‚ and metaphors are used to convey a deeper understanding of the experience of the poem. Heaney also uses these literary devices to help express his theme. The theme implies that pleasure does not last and decays like everything else. Throughout this poem‚ Heaney uses multiple tones to help get a better idea of the experience of picking blackberries. In the first stanza he is excited and enthusiastic about going to pick the blackberries. By describing

In nuclear physics and nuclear chemistry‚ nuclear fission refers to either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei)‚ often producing free neutrons and photons (in the form of gamma rays)‚ and releasing a very large amount of energy‚ even by the energetic standards of radioactive decay. The two nuclei produced are most often of comparable but slightly different sizes‚ typically with a mass ratio of products of about

beta radiation not spreading far around the body‚ this keeps tissue damage mostly limited over the intended area. After the use of iodine-131 by a patient the majority of the radionuclide clears the body after around three days through radioactive decay and also through sweating and urination. For this reason‚ patient isolation is advised due to iodine-131 being a gamma radiation emitter. Radioactive iodine may still be present in small amounts in the weeks after administration due to the thyroid
