of forgetting – specifically trace decay‚ displacement‚ interference and/or cue dependent forgetting. Forgetting from STM is usually explained in terms of the information being removed from a limited capacity store. This is due to a lack of availability. The capacity and duration of LTM are in effect unlimited. Not being able to retrieve information from LTM may be due to lack of accessibility. One explanation for forgetting in short term memory is trace decay. This explanation of forgetting in

Rutherford directed a narrow beam of α-particles‚ all of the same kinetic energy‚ in an evacuated container at a thin gold film‚ in order to identify the structure of an atom: The α-particles need to be of the same kinetic energy otherwise slow α-particles would be deflected more than faster α-particles on the same initial path. The container needs to be evacuated

In Joseph Conrad’s book Heart of Darkness ‚ Conrad represents the decay of the indigenous scenery as a metaphor to the decay within developed countries‚ specifically in England. This decay is a direct result of the actions taken by the society within this indigenous scenery. Within the book Heart of Darkness greed is a immense description toward the English and the scenery

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

and so iodine 131 can treat thyroid disorders (e.g. tumours) Iodine 131 has a half life of just over 8 days‚ emits beta particles and gamma rays as it decays. This half life is long enough for it to be transported form where it is produced to where it needs to be used but it is also short enough to minimise patients exposure to radiation It decays into non-radioactive gas‚ Xenon 131‚ which can easily escape without interfering bodily functions Beta particles can destroy abnormal tissue.

8.01 Lab Report FLVS The purpose of this hands-on lab is to model the concept of half-life using a sample to represent radioactive atoms. Materials 200 M&M® candies‚ pennies‚ or other small candy/item with two distinct sides shoe box or other small box with a lid Procedure 1. Place 200 candies in the shoe box‚ lettered sides up. The candies will stand for atoms of a hypothetical radioactive element. 2. Cover the box and shake it vigorously for three seconds. This is one time interval.

Forgetting is the inability to recall or recognise information that was once stored in the memory and is now not available or cannot be accessed. There are four main theories to forgetting; trace decay‚ cue dependant‚ displacement and interference. Displacement seeks to explain forgetting in the short term memory. According to Shiffrin and Atkinson’s model of memory‚ the short term memory has certain characteristics such as limited capacity so if information is not rehearsed‚ it would be forgotten

The bizarre outcome is further emphasized throughout by the symbolism of the decaying house‚ which parallels Miss Emily ’s physical deterioration and demonstrates her ultimate mental disintegration. Emily ’s life‚ like the house which decays around her‚ suffers from lack of genuine love and care. The characteristics of Miss Emily ’s house‚ like her physical appearance‚ are brought about by years of neglect. For example‚ the house is located in what was once a prominent neighborhood
