The positron decay of 15O goes directly to the ground state of 15N; no excited states of 15N are populated and no gamma rays follow the beta decay. Yet a source of 15O is found to emit gamma rays of about 0.5 MeV. Explain the origin of these gamma rays. Solution When a nucleus has too many protons, it tends to positron decay. A positron is an antimatter beta particle. When a positron meets with an electron it annihilates it! Both particles disappear and two gamma rays are produced instead. Electron–positron annihilation e + e+ + When a low-energy electron (beta particle) annihilates a low-energy positron (antielectron), they can only produce two or more gamma ray photons, since the electron and positron do not carry enough mass-energy to produce heavier particles, and conservation of energy and linear momentum forbid the creation of only one photon. When an electron and a positron collide to annihilate and create gamma rays, energy is given off. Both particles have a rest energy of 0.511 mega electron volts (MeV). When the mass of the two particles is converted entirely into energy, this rest energy is what is given off. The energy is given off in the form of the aforementioned gamma rays. Each of the gamma rays has energy of 0.511 MeV. This the reason why when rays originates in radioactive decay of Oxygen-15 by positron emission.

Radiation interactions
This document discusses the interaction of ionizing radiation with matter. It describes three main types of ionizing radiation: photons, charged particles, and neutral particles. For photons, the key interaction mechanisms are coherent scattering, the photoelectric effect, the Compton effect, and pair production. Charged particles like electrons and protons interact through soft collisions, hard collisions, and delta ray production. Neutral particles like neutrons interact primarily through scattering, absorption, and fission. The document provides details on the energy transfers and secondary emissions that result from each interaction mechanism.
Basic Interactions Between X Rays and Matter
X-rays can interact with matter through various processes. The most common interactions in diagnostic radiology are the photoelectric effect, Compton scattering, and coherent scattering. In the photoelectric effect, an incoming x-ray photon ejects an inner shell electron, leaving behind characteristic radiation. Compton scattering involves x-ray photon deflection by a free electron, producing scatter radiation. Coherent scattering changes a photon's direction but not its energy. These interactions have different probabilities depending on the photon energy and the electron binding energy.

This document discusses the dual wave-particle nature of X-rays and their interaction with matter. It notes that X-rays can behave as both waves that propagate through space, as well as particles called photons. The key interactions discussed are photoelectric effect, Compton scattering, and pair production.
The photoelectric effect results in a photon being absorbed by an atom, ejecting an electron and leaving the atom ionized. Compton scattering involves a photon ejecting an electron from an atom but also being deflected and losing some energy. Pair production occurs when a photon interacts near the nucleus of an atom and transforms into an electron-positron pair.

Minooka Valence Electros
Valence electrons are the outermost electrons of an atom that can be gained or lost to form ions. Atoms are most stable when they have 8 valence electrons, as this allows them to achieve a full valence shell configuration. Atoms will gain or lose electrons through bonding to reach the stable configuration of 8 valence electrons. Metals tend to lose or gain one electron to achieve stability, while non-metals gain or lose 7 electrons. During flame tests, atoms absorb energy and their electrons become excited, moving to higher energy states. When the electrons fall back to the ground state, they emit photons of light of specific colors.
Nuclear
The document discusses several topics in atomic and nuclear physics:
1) Light can be described as photons and the photoelectric effect occurs when light ejects electrons from metal surfaces.
2) Compton scattering demonstrates that X-rays lose energy when scattered, showing them to have particle-like properties.
3) X-rays are produced when high-energy electrons interact with atoms, and their wavelength depends on the electron's lost kinetic energy.
4) Light exhibits both wave and particle properties in experiments, known as wave-particle duality.

Meredith Ward is the assistant chief accountant at Frazier Company, .pdf
Meredith Ward is the assistant chief accountant at Frazier Company, a manufacturer of computer
chips and cellular phones. The company presently has total sales of $20 million. It is the end of
the first quarter. Meredith is hurriedly trying to prepare a trial balance so that quarterly financial
statements can be prepared and released to management and the regulatory agencies. The total
credits on the trial balance exceed the debits by $1,000. In order to meet the 4 p.m. deadline,
Meredith decides to force the debits and credits into balance by adding the amount of the
difference to the Equipment account. She chooses Equipment because it is one of the larger
account balances; percentage-wise, it will be the least misstatedMeredith “plugs” the difference!
She believes that the difference will not affect anyone’s decisions. She wishes that she had
another few days to find the error but realizes that the financial statements are already late.
Who are the stakeholders in this situation?
What are the ethical issues involved in this case?
What are Meredith’s alternatives?
Solution
Part A
The stakeholders in this situation are:
- the Frazier company, the company and its shareholders.
- Meredith Ward who is employee working at a position of assistant chief accountant.
- Users of the company’s financial statements.
Part B
Meredith\'saction of adding $1,000 to the Equipment account is unethical. The total of equipment
account is intentionally misstated. The misstatement of equipment account by $1000 will also
result into misstatement of other account by $1000 to avoid error that may arise due to
imbalance. If the amount would have been immaterial and there is no intention to commit fraud
(cover up an embezzlement or other misappropriation of assets), Meredith’s action might not be
considered unethical in the preparation of interim financial statements. However, if Meredith is
considered to be violating a company accounting policy by her action, in that case her behaviour
is believed to be unethical.
Part C
Meredith’s alternatives are:
1. Identify the error causing the imbalance though it requires more time than deadline
2. She should honestly inform her supervisor of the imbalance and suffer the consequences.
3. making the adjustment in the next quarter, identifying the error after deadline.

account balances; percentage-wise, it will be the least misstatedMeredith “plugs” the difference!
She believes that the difference will not affect anyone’s decisions. She wishes that she had
another few days to find the error but realizes that the financial statements are already late.
Who are the stakeholders in this situation?
What are the ethical issues involved in this case?
What are Meredith’s alternatives?
Solution
Part A
The stakeholders in this situation are:
- the Frazier company, the company and its shareholders.
- Meredith Ward who is employee working at a position of assistant chief accountant.
- Users of the company’s financial statements.
Part B
Meredith\'saction of adding $1,000 to the Equipment account is unethical. The total of equipment
account is intentionally misstated. The misstatement of equipment account by $1000 will also
result into misstatement of other account by $1000 to avoid error that may arise due to
imbalance. If the amount would have been immaterial and there is no intention to commit fraud
(cover up an embezzlement or other misappropriation of assets), Meredith’s action might not be
considered unethical in the preparation of interim financial statements. However, if Meredith is
considered to be violating a company accounting policy by her action, in that case her behaviour
is believed to be unethical.
Part C
Meredith’s alternatives are:
1. Identify the error causing the imbalance though it requires more time than deadline
2. She should honestly inform her supervisor of the imbalance and suffer the consequences.
3. making the adjustment in the next quarter, identifying the error after deadline.

Discuss the term renaissance (what does it mean) and the developmen.pdf
Discuss the term renaissance (what does it mean?) and the development of the Italian
Renaissance. Describe its features and some of its notable figures - artistic and literary. What is
new about this time and what themes are based on past art, architecture, and literature? What
relationship does the Italian renaissance have to the Protestant reformations? Respond to two
other people
Solution
The term ‘renaissance ‘ accurately means rebirth in a contracted sense it is used to describe the
revival of interest in the classical civilization of Greece and Rome renaissance was marked by a
series of new development in the field of art ,literature, religion, philosophy, science and politics
.the period of served as a bridge between medieval and modern west Europe
Renaissance began with the rediscovery of Greco –roman evolution which had been neglected
during the middle ages .it emphasized reason a questioning attitude experimentation and free
enquiry
This is contrasted with medieval reason with faith authority and tradition it glorified the
individual and approved worldly pleasure
Art and architecture during renaissance was in fluenced by classical Greece ad Rome renaissance
painting emphasized realism attention to detail and desire for perfection
In the era of Renaissance Literature, it was considered as division between the middle ages and
modern era. The Humanists considered that the man should be considered as subject of study and
not god. Printing press was one of the inventions during that era. Famous Writers include
William Shakespeare, John Milton, Philip Sidney
During the late 15thCentury is when ItalianRenaissance had started in Tuscany. It is well known
for cultural achievements. The work also includes literatures, Art, Architecture etc.
In the course of Renaissance the principles of art and architecture became integrated in the
recognition of classical antiquity. Florence had become the centre of culture and artistic event for
art. Artist had begun to appear from the role of artisan in which oil based paints were used for the
first time at this period. Artist here started to paint everyday life instead of religious scene. One
of the famous painter being Michelangelo, Leonardo Da vinci.
The causes for reformation was due to Political, Economic, Intellectual etc..
Consider a binary SNP matrix M with 1 representing the derived allele.pdf
Consider a binary SNP matrix M with 1 representing the derived allele, and 0 as the ancestral
allele. The SNP matrix has n haplotypes. The HAF vector of a haplotype h in M, denoted c_h, is
obtained by taking the binary haplotype vector and replacing non-zero entries (derived alleles
carried by the haplotype) with their respective frequencies in the sample. Define the HAF score
of h as: HAF (h) sigma_j c_h[j] where the sum proceeds over all segregating sites j in the
genomic region. Derive an expression for the Expected value of HAF (h) for h randomly
sampled from a neutrally evolving sample of n individuals.
Solution
SNP (Single Nucleotide Polymorphism)
Frequency of SNPs is greater than that of any other type of polymorphism.
Having the understanding of the structure and frequencies of haplotypes is very important for
associating genetic polymorphisms with a given trait. It also helps in inferring the genetic
genealogy of alleles in a population.
Single nucleotide polymorphism (SNP) haplotypes can be determined without ambiguity when
an individual does not have more than one heterozygous site in a given genomic region.
The Haplotype Allele Frequency (HAF) score assigned to individual haplotypes in a sample
naturally captures many of the properties shared by haplotypes carrying a favored allele.
Haplotype: Combinations of genetic variants occurring on the same DNA molecule. Each gene
in the diploid genome has two sequences, one on each haplotype.
Methods for detecting the genomic signatures of natural selection have been heavily studied.
They have been successful in identifying many selective sweeps.
For most of these sweeps, the favored allele remains unknown, making it difficult to distinguish
carriers of the sweep from non-carriers.
In an ongoing selective sweep, carriers of the favored allele are likely to contain a future most
recent common ancestor.
a) Expected value of HAF (h) for h randomly sampled from a neutrally evolving sample of n
individuals.
Consider a neutrally evolving sample of n individuals. We assume that all sites are biallelic, and
at each site, we denote ancestral alleles by 0 and derived alleles by 1. We also assume that all
sites are polymorphic in the sample. The HAF vector of a haplotype h, denoted by c, is obtained
by taking the binary haplotype vector and replacing non-zero entries (derived alleles carried by
the haplotype) with their respective frequencies in the sample. For parameter , we define the -
HAF score of c as:
where the sum proceeds over all segregating sites j in the genomic region. The 1-HAF score of a
haplotype amounts to the sum of frequencies of all derived alleles carried by the haplotype. The -
HAF score is equivalent to the -norm of c raised to the th power..

Can someone explain to me the classification of PRRs in immuniology
Classification of PRRs
: a) signaling b) endocytic
Solution
Prr are pattern recognition receptors, which play a very crucial part in immune system.
On the basis of ligand specificity, localisation , function and evolutionary relation ships , they
can be classified into two
A) signalling prr. They include large family of cytoplasmic NOD like receptors, and membrane
bound TOLL like receptors
B) endocytic prr . They engulf and destroy micro organisms, diaease causing antigens with the
help of phagocytes without any relay of intra cellular signals..

All Newsweek (March 20. 2011) Theyre the sort of scores that driv.pdf
All Newsweek (March 20. 2011) They\'re the sort of scores that drive high-school history
teachers to drink. When NEWSWEEK recently asked 1,000 U S. citizens to take America\'s
official citizenship test 30 percent couldn\'t name the vice president Seventy-five percent
couldn\'t correctly say why we fought the Cold War forty-five percent were unable to define the
Bill of Rights. And 6 percent couldn\'t even circle Independence Day on a calendar. Don\'t get us
wrong: civic ignorance is nothing new. For as long as they\'ve existed. Americans have been
misunderstanding checks and balances and misidentifying their senators. And they\'ve been
lamenting the philistinism of their peers ever since pollsters started publishing these dispiriting
surveys back in Harry Truman\'s day. (He was a president, by the way) According to a study by
Michael X. Delli Carpini, dean of the Annenherg School for Communication, the yearly shifts in
civic knowledge since World War II have averaged out to \"slightly under I percent.\" In a
sample of 10 individuals, what is the probability 4 arc could not name the vice president? In a
sample of 12 individuals what is the probability at least 8 arc not able to correctly say why we
fought the Cold War? In a sample of 15 individuals, what is the probability no more than 10 are
unable to define the Bill of Rights? In a sample of 9 individuals, what is the probability that 2, 3,
4, or 5 could not circle Independence Day on a calendar?

The positron decay of 15O goes directly to the ground state of 15N; n.pdf
- 1. The positron decay of 15O goes directly to the ground state of 15N; no excited states of 15N are populated and no gamma rays follow the beta decay. Yet a source of 15O is found to emit gamma rays of about 0.5 MeV. Explain the origin of these gamma rays. Solution When a nucleus has too many protons, it tends to positron decay. A positron is an antimatter beta particle. When a positron meets with an electron it annihilates it! Both particles disappear and two gamma rays are produced instead. Electron–positron annihilation e + e+ + When a low-energy electron (beta particle) annihilates a low-energy positron (antielectron), they can only produce two or more gamma ray photons, since the electron and positron do not carry enough mass-energy to produce heavier particles, and conservation of energy and linear momentum forbid the creation of only one photon. When an electron and a positron collide to annihilate and create gamma rays, energy is given off. Both particles have a rest energy of 0.511 mega electron volts (MeV). When the mass of the two particles is converted entirely into energy, this rest energy is what is given off. The energy is given off in the form of the aforementioned gamma rays. Each of the gamma rays has energy of 0.511 MeV. This the reason why when rays originates in radioactive decay of Oxygen-15 by positron emission
