Calculate the effects of the following pulse sequences on thermal equilibrium magnetization.

/in /by

 (a) In a sample of 1000 atoms,if 50 atoms decay in 5seconds, what is the radioactivity measured in mCi, of the sample?

b) in order to produce a level of radioactivity of 1mCi, how many nuclei of 99mTc (

?

= 3.22X10^(-5)s^(-) ) must be present? What mass of the radionuclide does this correspond to?(Avogadro’s number is 6.02X10^(23).

c) A radioactive sample of 99mTc contains 10mCi activity at 9 am.What is the radioactivity of the sample at 3pm on the same day.

2) In a nuclear medicine scan using 99mTc, the image SNR for a 30-min scan was 50:1 for an injected radioactive dose of 1 mCi (3.7X10^(7) disintegrations per second). Imaging began immediately after injection.

a) if the injected dose were doubled to 2mCi, what would be the image SNR for a 30-min scan?

b) if the scan time were doubled to 60min with an initial dose of 1mCi, what would be the image SNR?

3) Assuming that there are 6.7X10^(22) protons in 1cm^(3) of water, what is the magnetization contained within this volume at a magnetic field strength of 1.5T?

4) Calculate the effects of the following pulse sequences on thermal equilibrium magnetization. The final answer should include x,y, and z components of magnetization.

a) 90x (a pulse with tip angle 90 degrees , applied about the x axis).

b)80x.

c) 90x 90y (the second 90 degrees pulse is applied immediately after the first).

d)80x80y

This assignment is due on Saturday January 20, 2013 at 6am EST, it is very important to use APA format throughout this entire assignment and the similarity scores cannot be more than 15{0e601fc7fe3603dc36f9ca2f49ef4cd268b5950ef1bbcf1f795cc00e94cdd119}. Were require you must include an abstract, title page , page number, and a reference list all formatted in APA. And it is important that you clearly present the report in different sections as the questions and below underlining each section as you give the responses to avoid confusing .
COMMUNITY ASSESSMENT (100 Points Total) Provide a report based on the outline below. At least 8 pages excluding title and references page.
The following categories are grouped according to community systems, and will be the focus of this community assessment. Much of the data will be found through computer databases, windshield survey and talking with key informants in the community if possible . Cite or reference each source of data collected.
SECTION ONE: Impacts of Health and Social Services (Section is worth 20 Points)
Location and History of Community or population chosen ( i.e., when did the parish program or clinic or homeless shelter start and who started it?)
Determine what geographical area your Community Assessment should consider. It should be census track (very small) or zip code level OR (large) at the county, and city levels. Just be sure to be able to collect enough data to complete the template for your chosen community.
Vital and Demographic Statistics of the Community in General
Population density
Population; composition ( gender, age, and race distribution and ethnic origin )
Population characteristics ( marital status and family types )
Mortality characteristics ( infant & maternal mortality rates, leading cause of death )
Morbidity characteristics ( incidence and prevalence rates of specific diseases )
Values, Beliefs, and Religious Practices – demonstrate a good understanding of the underlying beliefs and values of the population chosen.
Health & Social…

Anton van Leewenhoek
Leopold Auenbrugger
Edward Jenner
Gabriel Andral
Rudolf Virchow
Gregor Mendel
Louis Pasteur
Paul Ehrlich
Robert Koch
Karl Landsteiner
Rosalind Franklin

For this writing assignment you are to choose two individuals from our timeline. The individuals should be separated by time. Here is the scenario: you are the more contemporary (current) of the two medical pioneers and you are writing your memoirs. You are to write on how your predecessor influenced your field of study or the direction of your research.
Speculate on how future generations will benefit from these contributions. Please include at least two specific events which occurred and correlate them.
When completing this assignment, you should include, at MINIMUM, the following:
The name of the historical individual you are portraying and the date you are writing your memoir
The type of research you are engaged in
The individual(s) that you would like to acknowledge
How your predecessor influenced you
How future generations will benefit
Give your memoir an appropriate title
Minimum of 500 words & 4 paragraphs (Max. 800 words & 7 paragraphs) not including your list of citations and free of spelling and grammatical errors.
