Moving into Administrative Work with a Masters in Education Essay Example

Moving into Administrative Work with a Masters in Education Essay Example Moving into Administrative Work with a Masters in Education Essay Moving into Administrative Work with a Masters in Education Essay The career of a teacher can be told in the stories they carry with them from the classroom; the students they have had an impact on, the lessons they have taught, the faces they have seen grow, and the years which they have dedicated to a school. There is much honor in the work of a teacher and those who love education often find themselves traveling down various paths throughout their career. In fact, many teachers find that at some point in their careers they are interested in moving into the administrative end of education, in which there are many fine careers that help to shape the curriculum and operations of our schools. Typically what many of these positions will require, however, is a Masters in Education; a degree that would have traditionally required someone to go back to school to earn. Many times the thought of juggling the schedule necessary to complete such a degree in this conventional manner is too overwhelming for older students who have had a break in their schooling and now have many responsibilities to which to attend. But with some research it is often duly noted that online degree programs are more prevalent than ever before; a result of the continued growth and popularity of the Internet. More and more people are recognizing the benefit of online learning and utilizing the flexibility and convenience of the Internet to pursue their goals. With the ability to earn a Masters in Education online, teachers are able to continue their work in the classroom and begin their journey towards the next phase in their career. The convenience of completing their work during off-hours gives them far more flexibility and the time they need to really buckle down and earn the degree that will deliver them with many additional opportunities.

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.
