The Rings of Saturn There are many planetary subsystems with.pdf
The Rings of Saturn There are many planetary subsystems within our solar system. Most of the
planets have moons orbiting them, but only theuj2 Jovian planets have rings. On no planet are the
rings more enchanting to behold than those of Saturn. The sixth planet boasts 7 primary rings, A
through G. From the planet outward they are: D,C,B,A,F,G, and E. The extent of the E ring is truly
enormous. At 26 Saturn diameters, it is the largest planetary ring in the solar system. With a small
telescope, however, it is the astonishing view of the A and B rings and the Cassini division
between them that stands out so spectacularly. Figure 1 shows the orientation and relative
positioning of the primary ring structures and moons of Saturn. rigure 1 - satum with Rings and
Moons (Credit: NASA/IPL) The rings are composed of icy water and dust ranging in size from

particulates to large meter sized boulders (Figure 2). Some of the ring material clumps together
forming elongated aggregate debris. Some of these structures are loosely held together and may
disaggregate according to the forces and momentum governing their motion. Data from the
Cassini spacecraft suggests an interesting cascade of material from the inner rings onto Saturn.
Complex inorganic grains embedded in water were discovered to be freefalling in Saturn's
gravitational field onto the upper atmosphere. The material included particulates combined with
gases such as: water, silicates, ammonia, methane, and carbon dioxide. Additionally, some of the
gas had sufficient electric charge to be captured and accelerated by Saturn's planetary magnetic
field causing those particles to spiral along trajectories determined by the field line orientation.
Figare 3 - Influence of Saturn's Magnetic Field (Credit: NASA/IPL) Even though other forces
generated from electric and magnetic fields have some influence on the ring material, it is gravity
that keeps the rings bound in their orbits. The planet has help in this regard with a few moonlets
such as Pan orbiting in the Encke Gap between the A and F rings to shepherd the material. The A,
B, and C, main rings are less than 100 meters thick in most places and it is estimated that all the
rings were developed in only the last few hundred million years. The shattering of a comet or a
small moonlet torn apart by Saturn's gravity could have provided the material from which the rings
are composed.1. If the average thickness of the rings is 100 meters, what is the ring volume in m3
? Assume all the rings are combined into one ring structure of height 100m that extends from r=
6.7107m to R=1.4108m above Saturn's equator. The equation to calculate the volume is:
VolumeofRing=(R2r2)h 2. If the density of the ring is similar to water at 1000kg/m3, what is the
mass of the ring? Density=volumemass 3. Cassini measured the mass of Saturn's rings and it is
now estimated to be about 40% of the mass of.

The Protocol We present the protocol sequentially though if.pdf
The Protocol We present the protocol sequentially, though if we are concerned with minimizing the
number of back-and-forth rounds we can send some of the messages in parallel with each other
(and use some additional shortcuts) to achieve a 4 round protocol. - Input: A has input (a0,a1){0,1}
2 and B has input b{0,1}. - Desired Output: A should receive no output while B should receive ab{0
,1}. 1. BA:B chooses u{0,1}n, draws (k,z)Com(u) and sends z to A. 7 2. AB: A chooses u{0,1}n and
sends u to B. 3. AB:A draws (N,e,d)RSAGen() and sends (N,e) to B. 4. BA:B sends (y0,y1)ZN2 to
A where y0 and y1 are prepared as follows (recall b is B's input bit): - yb is set to yb=xe for a
random xZN; . y1b is set to y1b=uu where u and u are the strings used in rounds 1 and 2(
indicates the bit-wise XOR of two strings; we are using that since n=log(N), any n-bit binary string
can be converted to an integer modN ). 5. BA : B and A use the zero knowledge proof system with
B playing as the prover and A playing as the receiver, where: Statement: The statement which is
used as common input to both players is (z,u,y0,y1)L5. BA:B and A use the zero knowledge proof
system with B playing as the prover and A playing as the receiver, where: - Statement: The
statement which is used as common input to both players is (z,u,y0,y1)L where membership in L
holds if there exists (k,u,i) such that Decom(z,k)=u and yi=uu -Witness: B uses (k,u,1b) as his
witness, where k is the decommitment string from the first round, u is the committed value in the
first round and b{0,1} is B's input bit. If A rejects B's proof then A aborts the protocol; otherwise A
continues. 6. AB:A computes (x0,x1)ZN by setting xi=yid for i=0,1 where d is the secret RSA
exponent generated in round 3. Additionally, A draws r0,r1{0,1}n and sends (r0,r1,w0,w1) to B
where wi=xi,riai{0,1} for i=0,1. - Output: B outputs the bit wbx,rb{0,1}. Intuition. In order to
understand the protocol, first imagine that the protocol consists only of rounds 3,4,6 and in round 4
, B chooses yb as stated above, but draws y1bZN. This simpler protocol will satisfy correctness
(since B will output ab ), and it will be secure against a corrupt A (since the only information sent
by B is (y0,y1) and both yi are simply random elements of ZN ). However, security against B is
problematic since B could choose x0,x1ZN and set yi=xie for i=0,1 and then would be able to learn
both of A's bits (a0,a1). So the role of the extra rounds is essentially to boost security against B.
So to summarize, the simpler scheme is secure as long as B generates (y0,y1) as he is supposed
to (i.e., if yb=xe for random xZN and y1bZN ), but fails if B is able to deviate. At a high level, the
function of the extra rounds is to ensure that one of the two yi is random in ZN. This works by
running a type of "coin flipping" procedure in rounds 1 and 2 , and then using the ZK proof in round
5 to prove that one of the yi is equal to the output of this procedure (B proves th.

The protocol will use the following building blocks The Inn.pdf
The protocol will use the following building blocks. The Inner Product Prediction Challenge for
RSA. Recall that the RSA based cryptographic constructions involve a composite integer NN
where N=pq for large primes p,qN. Additionally, a public exponent e is chosen along with N,
whereas the secret exponent d satisfies de =1mod(p1)(q1) and is known by only one of the two
players. Recall that de=1mod(p1)(q1) ensures xed=xmodN, whereas given (N,e), recovering d is
as hard as factoring N. In the protocol below we will write (N,e,d)RSA.Gen() to indicate that (N,e,d)
are generated as above. Finally, recall that the RSA assumption assumes that when (N,e,d)RSA
.Gen () and xZN is drawn, one cannot output x if given (N,e,y) where y=xe (of course if one is
given (N,e,d,y) then one can simply compute x=yd ). In homework 6 1, problem 3 we saw the
following "inner product prediction" version of the RSA game: given (N,e,y,r) where (N,e,d)RSA.
Gen(),xZN,y=xe and r{0,1}n where n=log(N), output x,r. We showed that any adversary who can
win the inner product prediction game for RSA with probability 1/2+ for non-negligible >0 can be
used to build (via the techniques of Goldreich-Levin) another adversary who can break the RSA
assumption with non-negligible probability. Blum's Commitment Scheme. The protocol below will
use Blum's non-interactive commitment scheme as a building block. While Blum's scheme allows
Alice to commit to a single bit, Alice can commit to an n-bit string by committing independently to
each bit. For an n-bit string u{0,1}n, we write (z,k)Com(u) to indicate that z and k are respectively
the collections of commitment and decommitment strings when Blum's scheme is used to commit
to each bit of x. Recall binding says that for any z, there is at most one k such that the
decommitment procedure succeeds when run with input (z,k). Recall the hiding game for this
commitment scheme is played between a challenger C and adversary A as follows. - A sends (u0,
u1) to C where u0,u1{0,1}n; - C draws b{0,1} and (z,k)Com(ub) and sends z to A; - A sends b{0,1}
to C signaling the end of the game; A wins if b=b. Hiding security demands that no efficient
adversary can win this hiding game except with probability 1/2+ for negligible >0.Zero-Knowledge
Proofs. Our OT protocol will use a ZK proof system as a key building block for one of the parties to
prove to the other that a particular quantity in the protocol has been computed correctly. As a
simple example to help understand the role that the ZK proof plays, imagine that early on in the
protocol, A sends z to B where (z,k)Com(0). Then while z is supposed to be a commitment to 0 ,
hiding says that B cannot actually tell what value is hidden inside, so it is possible that an
adversarial A might have actually drawn (z,k)Com(1). In this case, it might be useful to have A
prove to B using a ZK proof that in fact z is a commitment to 0 . For this to work, the statement is "
zL " where membership in L holds whenever ther.

character count both files (1etcers only) Enter 2 for total word count both files (no punctuation)
Enter 3 for unique word count both files Enter 4 for unique word count only in textl and only in textz
Enter 5 for unique words eount in both files Enter 6 to quit Each of the first five options should be
handled by one function that you write. For example, with option 1, this call would be made: ch1,
ch2 = charcount (text1, text 2) t handle option 1 where text1 and text2 are strings of text read from
the selected files and ohl and ch2 are the total number of characters in each file. In a similar
manner the other functions would be: wordi, word2 = wordsopt2 (text1, text2) i handle option 2 etc
for the other options - use good naming conventions. You will also need a menu function which

THE PROBLEMATIC WHISTLEBLOWER Paul ODoherty is the ethics o.pdf
THE PROBLEMATIC WHISTLEBLOWER Paul O'Doherty is the ethics officer for a medium-sized
petroleum company. The company has a comprehensive ethics program that is his responsibility.
The program includes a code of business conduct that outlines the values that guide behaviour,
identifies conflicts of interest, specifies appropriate and inappropriate practices, and provides an
approach to reporting violations or suspected wrongdoing. One aspect of the reporting system is
an employee Hotline; employees can contribute in written form, such as by email, or orally, by
telephone or in person. Participants must identify themselves and all communications go directly
to Paul. He reports directly to the corporate secretary and legal counsel; the identity of the
employee is not disclosed and confidentiality is maintained except in rare cases where there is
legal action. Paul is a member of the Ethics Practitioners' Association of Canada (EPAC).
According to EPAC, the skills of an ethics officer include "facilitating constructive dialogue on
ethics-related issues, analyzing ethics issues and problems, and providing coherent, realistic
solutions to ethical issues." 31 His job has been rewarding and he has enabled the company to
keep abreast of developments in the ethics area. The company has received awards for its ethics
program and is recognized as a leader in corporate ethics. Recently, Paul has been experiencing
a problem with the Hotline component of the ethics program. An employee is making numerous
complaints to the Hotline, almost weekly. The complaints cover many aspects of the employee's
department: unfair treatment by a supervisor, stealing of office supplies by coworkers,
management favouritism in assigning holidays, reporting an employee who is moonlighting. and
quality of service given to customers. All of the complaints have been investigated according to the
procedures outlined in the corporation's reporting guidelines. The investigations have been costly,
in terms of both money and time. None of the complaints has been determined to be justified and
many lack credibility. Paul has reluctantly concluded that the employee is a whiner or
troublemaker, but he cannot state this to others. It appears that the employee's reporting practices
have been damaging to department morale. The challenge now is to decide whether something
should be done about the situation. Questions What stakeholders are involved in this situation?
What actions should be taken to address this situation? What are the ethical implications of each
action? What ethical principle or principles should be followed in resolving this situation?.

The process for converting present values into future values.pdf
The process for converting present values into future values is called compounding or
discounting. This process requires knowledge of the values of three of four time-value-of-money
variables. Which of the following is not one of these variables?
Line A: 0%, 21%, 11% Line B: 0%, 21%, 11% Line C: 0%, 21%, 11%
Investments and loans base their interest calculations on one of two possible methods: the
simple or complex interest and the compound or uncomplicated interest methods.
The principal of the time value of money is probably the single most important concept in financial
management. One of the most frequently encountered applications involves the calculation of a
future value. The process for converting present values into future values is called . This process
requires knowledge of the values of three of four time-value-of-money variables. Which of the
following is not one of these variables? The duration of the investment (N) The inflation rate
indicating the change in average prices The interest rate (I) that could be earned by invested funds
The present value (PV) of the amount invested All other things being equal, the numerical
difference between a present and a future value corresponds to the amount of interest earned
during the deposit or investment period. Each line on the following graph corresponds to an
interest rate: 0%,11%, or 21%. Identify the interest rate that corresponds with each line. Line A:
Line B: Line C:Investments and loans base their interest calculations on one of two possible
methods: the interest and the interest methods. Both methods apply three variables-the amount of
principal, the interest rate, and the investment or deposit period-to the amount deposited or
invested in order to compute the amount of interest. However, the two methods differ in their
relationship between the variables. Assume that the variables I, N, and PV represent the interest
rate, investment or deposit period, and present value of the amount deposited or invested,
respectively. Which equation best represents the calculation of a future value (FV) using:
Compound interest? FV=(1+I)N/PVFV=PV+(PVIN)FV=PV(1+I)N Simple interest? FV=PVINFV=PV
+(PVIN)FV=PV(PVIN)Identify whether the following statements about the simple and compound
interest methods are true or false. Nicholai is willing to invest $35,000 for six years, and is an
economically rational investor. He has identified three investment alternatives (A, B, and C) that
vary in their method of calculating interest and in the annual interest rate offered. Since he can
only make one investment during the six-year investment period, complete the following table and
indicate whether Nicholai should invest in each of the investments. Note: When calculating each
investment's future value, assume that all interest is earned annually. The final value should be
rounded to the nearest whole dollar..
The problems associated with the nomenclature include a Sc.pdf
The problems associated with the nomenclature include:
a) Scientific name not italicised
b) Scientific name not underlined
c) Incorrect capitalisation
d) Unnecessary restatement of genus
e) No problem
The Linnaean system of nomenclature is widely used, but often incorrectly applied. Identify the
problems associated with the nomenclature in each of the following sentences. See The nature of
data lesson. "The most common species recorded on our transects was Eucalyptus Racemosa
ssp. Rossii (58%). The remaining 42% comprised four species that are locally common- E.
Mannifera, E. Macrorhyncha and E. Polyanthemos." "Many Australian tree species are widely
grown in California, especially those in the genus Eucalyptus. There are over two hundred species
of Eucalyptus currently being grown in California, several of which have naturalized. Dr. Matt Ritter
will discuss the implications of naturalized eucalypts in California, the controversy associates with
their propagation and removal, and the widespread myth of their allelopathy." We examined
climate sensitivity in Podocarpus lawrencei-Australia's only alpine conifer. Most of the Australian
macropods have suffered significant declines in numbers and/or distribution since European
settlement, some to extinction. There has been little adverse effect on the larger kangaroos (red
kangaroo (Macropus rufus), western grey kangaroo ( M. fuliginosus), eastern grey kangaroo
(Macropus giganteus).A composite linkage map was constructed from four individual maps for the
conifer Picea glauca. Comparisons with two other composite linkage maps developed for the
species complex P. mariana, P. rubens, and for P. abies revealed remarkable conservation of the
gene content. The combined information from these three Picea species validated and improved
large-scale comparisons between genera in the family Pinaceae by allowing identification of
linkage groups between Picea and Pinus, and between Picea and Pseudotsuga menziesii.
Evidence indicated instability in part of the P. menziesii genome. Overall, the macrostructure of the
Pinaceae genome was well conserved, which is notable given the Cretaceous origin of its main
lineages..
The patient is a male age 17 from Bethlehem Pennsylvania .pdf
The patient is a male, age 17 from Bethlehem, Pennsylvania. He was admitted to the clinic with a
deep, red, swollen abscess on the back-right shoulder. The patient is a student at a local high
school where he wrestles for the varsity team. The patients dad is a high school teacher and
wrestling coach and his mother is a human resources manager. The family has a history of high
blood pressure (paternal) and breast cancer (maternal). The teenager enjoys hanging out with his
friends and playing video games. Nine days ago after a match against a rival team, he noticed a
red lump on his shoulder. Four of his teammates had similar sores on their arms, chest, and face.
The young mans father applied a topical antibiotic ointment to the area and covered it with an
adhesive bandage.
A few days later, the young mans parents noticed that the bump appeared red and somewhat
swollen. Concerned, the boys father again applied antibiotic ointment, applied an adhesive
bandage, and held the son out of practice. The next day, the sore still appeared raised and
inflamed. After a few days, it began to feel hard and hot to the touch, and the patient often
complained of tiredness and headaches. He was febrile upon admission to the clinic. The abscess
on his shoulder is roughly 1.5 inches in diameter, with a yellowish center and weeping, crusted
tips.
Let's learn a little bit more about the skin.
Complete the blanks: (1),(2)
Skin consists of two principal parts, the epidermis, and the ___________(2) ________________.
The ___________(1) ________________ is the thin outer portion, composed of several layers of
epithelial cells. The outermost layer of the epidermis, the stratum corneum, consists of many rows
of dead cells that contain a waterproofing protein called keratin.
The ___________(1) ________________, when unbroken, is an effective physical barrier against
microorganisms composed mainly of connective tissue.
The ___________(2) ________________ is the inner, relatively thick portion of skin, composed
mainly of connective tissue. The hair follicles, sweat gland ducts, and oil gland ducts in the dermis
provide passageways through which microorganisms can enter the skin and penetrate deeper
tissues.
Perspiration provides moisture and some nutrients for microbial growth. However, it contains salt,
which inhibits many microorganisms; the enzyme lysozyme, which is capable of breaking down
the cell walls of certain bacteria; and antimicrobial peptides.
Sebum, secreted by oil glands, is a mixture of lipids (unsaturated fatty acids), proteins, and salts
that prevents skin and hair from drying out. Although the fatty acids inhibit the growth of certain
pathogens, sebum, like perspiration, is also nutritive for many microorganisms..

The protocol will use the following building blocks The Inn.pdf
The protocol will use the following building blocks. The Inner Product Prediction Challenge for
RSA. Recall that the RSA based cryptographic constructions involve a composite integer NN
where N=pq for large primes p,qN. Additionally, a public exponent e is chosen along with N,
whereas the secret exponent d satisfies de =1mod(p1)(q1) and is known by only one of the two
players. Recall that de=1mod(p1)(q1) ensures xed=xmodN, whereas given (N,e), recovering d is
as hard as factoring N. In the protocol below we will write (N,e,d)RSA.Gen() to indicate that (N,e,d)
are generated as above. Finally, recall that the RSA assumption assumes that when (N,e,d)RSA
.Gen () and xZN is drawn, one cannot output x if given (N,e,y) where y=xe (of course if one is
given (N,e,d,y) then one can simply compute x=yd ). In homework 6 1, problem 3 we saw the
following "inner product prediction" version of the RSA game: given (N,e,y,r) where (N,e,d)RSA.
Gen(),xZN,y=xe and r{0,1}n where n=log(N), output x,r. We showed that any adversary who can
win the inner product prediction game for RSA with probability 1/2+ for non-negligible >0 can be
used to build (via the techniques of Goldreich-Levin) another adversary who can break the RSA
assumption with non-negligible probability. Blum's Commitment Scheme. The protocol below will
use Blum's non-interactive commitment scheme as a building block. While Blum's scheme allows
Alice to commit to a single bit, Alice can commit to an n-bit string by committing independently to
each bit. For an n-bit string u{0,1}n, we write (z,k)Com(u) to indicate that z and k are respectively
the collections of commitment and decommitment strings when Blum's scheme is used to commit
to each bit of x. Recall binding says that for any z, there is at most one k such that the
decommitment procedure succeeds when run with input (z,k). Recall the hiding game for this
commitment scheme is played between a challenger C and adversary A as follows. - A sends (u0,
u1) to C where u0,u1{0,1}n; - C draws b{0,1} and (z,k)Com(ub) and sends z to A; - A sends b{0,1}
to C signaling the end of the game; A wins if b=b. Hiding security demands that no efficient
adversary can win this hiding game except with probability 1/2+ for negligible >0.Zero-Knowledge
Proofs. Our OT protocol will use a ZK proof system as a key building block for one of the parties to
prove to the other that a particular quantity in the protocol has been computed correctly. As a
simple example to help understand the role that the ZK proof plays, imagine that early on in the
protocol, A sends z to B where (z,k)Com(0). Then while z is supposed to be a commitment to 0 ,
hiding says that B cannot actually tell what value is hidden inside, so it is possible that an
adversarial A might have actually drawn (z,k)Com(1). In this case, it might be useful to have A
prove to B using a ZK proof that in fact z is a commitment to 0 . For this to work, the statement is "
zL " where membership in L holds whenever ther.

an employee Hotline; employees can contribute in written form, such as by email, or orally, by
telephone or in person. Participants must identify themselves and all communications go directly
to Paul. He reports directly to the corporate secretary and legal counsel; the identity of the
employee is not disclosed and confidentiality is maintained except in rare cases where there is
legal action. Paul is a member of the Ethics Practitioners' Association of Canada (EPAC).
According to EPAC, the skills of an ethics officer include "facilitating constructive dialogue on
ethics-related issues, analyzing ethics issues and problems, and providing coherent, realistic
solutions to ethical issues." 31 His job has been rewarding and he has enabled the company to
keep abreast of developments in the ethics area. The company has received awards for its ethics
program and is recognized as a leader in corporate ethics. Recently, Paul has been experiencing
a problem with the Hotline component of the ethics program. An employee is making numerous
complaints to the Hotline, almost weekly. The complaints cover many aspects of the employee's
department: unfair treatment by a supervisor, stealing of office supplies by coworkers,
management favouritism in assigning holidays, reporting an employee who is moonlighting. and
quality of service given to customers. All of the complaints have been investigated according to the
procedures outlined in the corporation's reporting guidelines. The investigations have been costly,
in terms of both money and time. None of the complaints has been determined to be justified and
many lack credibility. Paul has reluctantly concluded that the employee is a whiner or
troublemaker, but he cannot state this to others. It appears that the employee's reporting practices
have been damaging to department morale. The challenge now is to decide whether something
should be done about the situation. Questions What stakeholders are involved in this situation?
What actions should be taken to address this situation? What are the ethical implications of each
action? What ethical principle or principles should be followed in resolving this situation?.
The problem at the center of RSA is finding the eth root of.pdf
The problem at the center of RSA is finding the eth root of the ciphertext c modulo N where N = pq
is a product of (distinct) primes. This is hard to do for large N if you dont know the factors p and q,
but once you know p and q it becomes easy! Write a finction findRoot(c,e,p,q) which solves the
equation xe c mod N for x where N = pq.
The process for converting present values into future values.pdf
The process for converting present values into future values is called compounding or
discounting. This process requires knowledge of the values of three of four time-value-of-money
variables. Which of the following is not one of these variables?
Line A: 0%, 21%, 11% Line B: 0%, 21%, 11% Line C: 0%, 21%, 11%
Investments and loans base their interest calculations on one of two possible methods: the
simple or complex interest and the compound or uncomplicated interest methods.
The principal of the time value of money is probably the single most important concept in financial
management. One of the most frequently encountered applications involves the calculation of a
future value. The process for converting present values into future values is called . This process
requires knowledge of the values of three of four time-value-of-money variables. Which of the
following is not one of these variables? The duration of the investment (N) The inflation rate
indicating the change in average prices The interest rate (I) that could be earned by invested funds
The present value (PV) of the amount invested All other things being equal, the numerical
difference between a present and a future value corresponds to the amount of interest earned
during the deposit or investment period. Each line on the following graph corresponds to an
interest rate: 0%,11%, or 21%. Identify the interest rate that corresponds with each line. Line A:
Line B: Line C:Investments and loans base their interest calculations on one of two possible
methods: the interest and the interest methods. Both methods apply three variables-the amount of
principal, the interest rate, and the investment or deposit period-to the amount deposited or
invested in order to compute the amount of interest. However, the two methods differ in their
relationship between the variables. Assume that the variables I, N, and PV represent the interest
rate, investment or deposit period, and present value of the amount deposited or invested,
respectively. Which equation best represents the calculation of a future value (FV) using:
Compound interest? FV=(1+I)N/PVFV=PV+(PVIN)FV=PV(1+I)N Simple interest? FV=PVINFV=PV
+(PVIN)FV=PV(PVIN)Identify whether the following statements about the simple and compound
interest methods are true or false. Nicholai is willing to invest $35,000 for six years, and is an
economically rational investor. He has identified three investment alternatives (A, B, and C) that
vary in their method of calculating interest and in the annual interest rate offered. Since he can
only make one investment during the six-year investment period, complete the following table and
indicate whether Nicholai should invest in each of the investments. Note: When calculating each
investment's future value, assume that all interest is earned annually. The final value should be
rounded to the nearest whole dollar..
The problems associated with the nomenclature include a Sc.pdf
The problems associated with the nomenclature include:
a) Scientific name not italicised
b) Scientific name not underlined
c) Incorrect capitalisation
d) Unnecessary restatement of genus
e) No problem
The Linnaean system of nomenclature is widely used, but often incorrectly applied. Identify the
problems associated with the nomenclature in each of the following sentences. See The nature of
data lesson. "The most common species recorded on our transects was Eucalyptus Racemosa
ssp. Rossii (58%). The remaining 42% comprised four species that are locally common- E.
Mannifera, E. Macrorhyncha and E. Polyanthemos." "Many Australian tree species are widely
grown in California, especially those in the genus Eucalyptus. There are over two hundred species
of Eucalyptus currently being grown in California, several of which have naturalized. Dr. Matt Ritter
will discuss the implications of naturalized eucalypts in California, the controversy associates with
their propagation and removal, and the widespread myth of their allelopathy." We examined
climate sensitivity in Podocarpus lawrencei-Australia's only alpine conifer. Most of the Australian
macropods have suffered significant declines in numbers and/or distribution since European
settlement, some to extinction. There has been little adverse effect on the larger kangaroos (red
kangaroo (Macropus rufus), western grey kangaroo ( M. fuliginosus), eastern grey kangaroo
(Macropus giganteus).A composite linkage map was constructed from four individual maps for the
conifer Picea glauca. Comparisons with two other composite linkage maps developed for the
species complex P. mariana, P. rubens, and for P. abies revealed remarkable conservation of the
gene content. The combined information from these three Picea species validated and improved
large-scale comparisons between genera in the family Pinaceae by allowing identification of
linkage groups between Picea and Pinus, and between Picea and Pseudotsuga menziesii.
Evidence indicated instability in part of the P. menziesii genome. Overall, the macrostructure of the
Pinaceae genome was well conserved, which is notable given the Cretaceous origin of its main
lineages..
The patient is a male age 17 from Bethlehem Pennsylvania .pdf
The patient is a male, age 17 from Bethlehem, Pennsylvania. He was admitted to the clinic with a
deep, red, swollen abscess on the back-right shoulder. The patient is a student at a local high
school where he wrestles for the varsity team. The patients dad is a high school teacher and
wrestling coach and his mother is a human resources manager. The family has a history of high
blood pressure (paternal) and breast cancer (maternal). The teenager enjoys hanging out with his
friends and playing video games. Nine days ago after a match against a rival team, he noticed a
red lump on his shoulder. Four of his teammates had similar sores on their arms, chest, and face.
The young mans father applied a topical antibiotic ointment to the area and covered it with an
adhesive bandage.
A few days later, the young mans parents noticed that the bump appeared red and somewhat
swollen. Concerned, the boys father again applied antibiotic ointment, applied an adhesive
bandage, and held the son out of practice. The next day, the sore still appeared raised and
inflamed. After a few days, it began to feel hard and hot to the touch, and the patient often
complained of tiredness and headaches. He was febrile upon admission to the clinic. The abscess
on his shoulder is roughly 1.5 inches in diameter, with a yellowish center and weeping, crusted
tips.
Let's learn a little bit more about the skin.
Complete the blanks: (1),(2)
Skin consists of two principal parts, the epidermis, and the ___________(2) ________________.
The ___________(1) ________________ is the thin outer portion, composed of several layers of
epithelial cells. The outermost layer of the epidermis, the stratum corneum, consists of many rows
of dead cells that contain a waterproofing protein called keratin.
The ___________(1) ________________, when unbroken, is an effective physical barrier against
microorganisms composed mainly of connective tissue.
The ___________(2) ________________ is the inner, relatively thick portion of skin, composed
mainly of connective tissue. The hair follicles, sweat gland ducts, and oil gland ducts in the dermis
provide passageways through which microorganisms can enter the skin and penetrate deeper
tissues.
Perspiration provides moisture and some nutrients for microbial growth. However, it contains salt,
which inhibits many microorganisms; the enzyme lysozyme, which is capable of breaking down
the cell walls of certain bacteria; and antimicrobial peptides.
Sebum, secreted by oil glands, is a mixture of lipids (unsaturated fatty acids), proteins, and salts
that prevents skin and hair from drying out. Although the fatty acids inhibit the growth of certain
pathogens, sebum, like perspiration, is also nutritive for many microorganisms..
