Positron emission tomography - Essay Example Isotopes with the tendency to radioactivity refer to atoms with an unstable nucleus. The inner core, which consists of the nucleus, has unbalanced energy. The dense package of neutron and proton makes the nucleus unstable. The lack of stability is the basis for the decomposition process. Therefore, through decomposition, the nuclei transform its configuration and components to a less strength and steady condition. This decomposition obeys the exponential law, which states ‘the number of decomposition per second is always equivalent to the amount of the undecayed nuclei available.' The law is also applicable to the rate of decay (activity). The decay depends on the half-life of the nuclide. Half-life is the duration/time that a nucleus takes to be halved.Positrons refer to the subatomic molecules that are equal in mass to an electron with characteristic of carrying a positive charge. When the positron decay (ÃŽ ²+), its nuclei changes one of the core protons (p) to a neutron (n) , while emitting positron (ÃŽ ²+) to attain a positively charged nature referred to as neutrino (ÃŽ ½).Upon the release from the initial nucleus, the high positron moves across a few millimeters through the tissue until it attains thermalization, during the acquisition of thermal energy, the positrons arrive at thermal energies. They begin connecting with electrons either through annihilation that produce two 511 keV photons to take anti-parallel positrons frame or through development of the hydrogen.

Action Plans - Essay Example As the groups vision suggests, this year we will ensure that Whirlpool’s Innovation Group get a proper name by ensuring that Whirlpool products are the most preferred brands in the associated home of the near future. We will also ensure that every activity that is being carried out in the organization is in line with the mission by ensuring that our products empower our clients in homes across the world. Ladies and gentlemen, Whirlpool’s Innovation Group has set various goals to ensure that the company achieves its mission including; identifying technologies central the connected goals, integrating Whirlpool products with the connected home and ensuring that new technologies make customer’s lives easier. In addition, Whirlpool’s Innovation Group has gone a step further developing various corporate ventures. For instance, Whirlpool’s Innovation Group recently developed a partnership with universities (Smart Zones) as well as Tech Scouting. To achieve its various goals and objectives, Whirlpool’s Innovation Group is planning to establish a presence at one or more Smart Zones for developing connected home technologies for Whirlpool. Additionally, it is planning to establish a scouting group with the purpose of investigating developments in connected homes. Last and not least, the Whirlpool’s Innovation Group is planning to Leverage Smart Zone presence to facilitate technology scouting. As I close, allow me to stress on the action plans, if Whirlpool’s Innovation Group manages to effectively implement these actions plans success will be automatic. The number of connected will determine the metric of our actions home our products release to the market (Whirlpool Corporation, 2015). Results and Updates Full-Year 2015 Guidance.
