Consider the incompressible and irrotational flow around a Rankine half-body... Consider the
incompressible and irrotational flow around a Rankine half-body (cf. Figure 1). The flow can be
modeled using the superposition of a source at point (a. b) and a uniform flow in the redirection.
Suppose that we would like to model the flow around a halfbody that is inclined (relative to the
horizontal) at an angle alpha (i.e. it is rotated CCW by an angle alpha). Find the velocity
potential function Psi for the inclined half-body in terms of x and y coordinates. Find the stream
function Phi for the inclined half-body in terms of x and y coordinates. Utilizing your answer to
part (a), find expressions for the velocity components u and v. Utilizing your answer to part (b).
find expressions for the velocity components u and v. Show that the Laplacian of Psi is equal to
zero. Show that the Laplacian of Phi is equal to zero. Find an expression for the pressure
coefficient that is valid for all points in the flow. Neglect gravitational forces, and assume that
Bernoulli\'s equation applies.
Solution
ø = øUniform flow(UF) + øSource(S)
= - (q/2) ln(r )- Ux
‘q= volume flow rate per unit width
r- Radius
b) Stream function,
j = jUF + jS
= (q/2) - Vy
c) Velocity component from (a)
Ur= Ucos + m/(2r)
d) Velocity component from (b)
V = Usin
e) The equation for z component of vorticity is
v/ x - u/ y =
For irrotational flows , the condition irrotantionality is = 0
v/ x - u/ y = 0
Now in irrotantionality, the scalar function of ø is as follows
‘u = ø/x v= ø/y ………………(1)
Substituting this in vorticity equation, we get
2 ø/xy - 2 ø/yx
=2 ø/xy -2 ø/xy
= 0
Which illustrates that we can write velocity vector u = (u,v) as gradient scalar function of ø. i.e.
If u = ø, x u = 0
Substituting 1 in continuity equation (u/x + v/y= 0)
2 ø/x2 + 2 ø/y2 = 0
As from above we can see laplacian of ø is zero.
f) The equation for z component of vorticity is
v/ x - u/ y =
For irrotational flows , the condition irrotantionality is = 0
v/ x - u/ y = 0
Now in irrotantionality, the scalar function of ø is as follows
‘u = /x v= /y ………………(1)
Substituting this in vorticity equation, we get
2 /xy - 2 /yx
=2 /xy - 2 /xy
= 0
Which illustrates that we can write velocity vector u = (u,v) as gradient scalar function of ø. i.e.
If u = ø, x u = 0
Substituting 1 in continuity equation (u/x + v/y= 0)
2 /x2 + 2 /y2 = 0
As from above we can see laplacian of is zero.
g) Continuity equation, u/x + v/y= 0
Assuming liquid to be perfect with steady flow& neglecting gravity eulers equation can be
described as
u u/x + v v/y = - (1/p) p/x
u v/x + v v/y = - (1/p) p/y
Simplifying this equations
(u2/2)/x + v u/y = (p/p)/x
Adding & subtracting
/x ( u2/2 + v2/2 ) -/x ( (v2/2) + v u/y = - P/x
Rearranging,
/y (u2/2 + v2/2 + P/) = - u (v/x - u/y)
We know that equation for z component of vorticity is
v/x - u/y = 0 (for irrotational flows)
u2/2 + v2/2 + P/ = H (bernouli equation)
H is constant
If flow is uniform @ speeds U

Write a short essay that compares the stories of the birth of Jesus .pdfatulkapoor33
Write a short essay that compares the stories of the birth of Jesus by Matthew and Luke. What
parts of the Gospels point to the divinity of Jesus? How do the stories differ? Read any
footnotes.Be prepared to discuss the differences in how the Gospels begin and the meaning of the
texts.
Solution
Jesus’ birth takes place near the end of the reign of Herod the Great (Matt 2:1; Luke 1:5).
2. The names of the principal characters: Mary, Jesus’ future mother, and Joseph his adopted
father.
3. Mary is a virgin engaged to Joseph but they have not begun to live together nor have they
consummated their marriage (Matt 1:18; Luke 1:27, 34; 2:5).
4. Joseph is of Davidic descent (Matt 1:16-20; Luke 1:27; 2:4).
5. An angel from heaven announces the birth of Jesus (Matt 1:20-21; Luke 1:28-30).
6. Jesus is recognized as a son of David (Matt 1:1; Luke 1:32).
7. Jesus’ conception will take place miraculously i.e. through the Holy Spirit (Matt 1:18, 20;
Luke 1:35).
8. Joseph is not involved in the conception—unlike similar stories in the OT in which it is a
barren woman who conceives though through normal means (Matt 1:18-25; Luke 1:34).
9. The name Jesus is given by the angel prior to his birth (Matt 1:21; Luke 1:31). The Greek for
this in fact is strikingly similar which greatly increases the likelihood to hold on purely historical
critical grounds that this tradition predates both gospels:
10. Jesus is identified as “savior” by the angel (Matt 1:21; Luke 1:31).
11. Jesus is born after Mary and Joseph begin to live together (Matt 1:24-25; Luke 2:4-7).
12. Jesus is born in Bethlehem (Matt 2:1; Luke 2:4-7).
13. The family has a house in Bethlehem (Matt 2:10; Luke 2:7—which I believe refers to
Joseph’s ancestral home in Bethlehem rather than an “inn” or a stable).
14. The family settles in Nazareth sometime after the birth of Jesus (Matt 2:22-23; Luke 2:39,
51).(Matt 1:21): .And she will give birth to a son and you will call his name Jesus.(Luke
1:31): , .And you will give birth to a son and you will call his name Jesus..

Write a 500 word essay on: How Emotionally Intelligent am I? Using Daniel Goleman
article\"What makes a leader
Solution
Developing more emotional intelligence (EI) is very important for a successful career. When
individuals have high levels of EI, they build strong effective relationships and manage difficult
situations more successfully. Emotional intelligence is an intelligence having to do with
perceptive and understanding emotional information. Emotional information is in every place.
Emotions speak basic feeling states from one individual to other -- they mention urgent messages
such as \"let\'s get together\".
Psychologist Daniel Goleman fined five elements that make up emotional intelligence. These
are:
Leadership is build through emotional intelligence, which itself can only be achieved through
time, determination, and promise. Without emotional intelligence, leadership is weak,
inaccessible, and remote. True leaders show sympathy, kindness, and behave to their peers and
subordinates alike..
Why is it significant that many antibiotic resistance genes are foun.pdfatulkapoor33
Why is it significant that many antibiotic resistance genes are found on the loops of DNA (mini-
chromosomes) called plasmids?
1. Plasmids can be passed among cells—allowing rapid spread, even between species of bacteria.
2. Antibiotic resistance genes aren’t found on the main bacterial chromosome.
3. Antibiotics and antibiotic resistance genes are produced naturally, often by soil-dwelling
bacteria.
4. Point mutations that confer resistance to a drug can’t occur unless that drug is in the
environment.
Solution
1. Plasmids can be passed among cells—allowing rapid spread, even between species of bacteria.
Plasmids are the extra DNA carried by bacteria; they are transferred to other cells during the
process of conjugation. It is advantageous for the bacteria to carry bacterial resistance genes on
plasmids because they can be transferred from one bacteria to the other and can be transferred
even between species..

which of the following is true with respect to the 3 classes of chem.pdfatulkapoor33
which of the following is true with respect to the 3 classes of chemical messengers in the body.
a) hormones are released from endocrine cells and travel in the plasma to target cells b)
paracrines are proteins that are released from a secretory cell and travel through the plasma to
neighboring cells c) neurotransmitters are chemical messengers, which are released by the nerve
and bind to receptors on the postsynaptic cell d) both A and C e) all of the above
Solution
Correct answer is : All of the above
There are 3 types of Chemical messengers
1.Paracrines –
• Local chemical messengers
• Exert effect only on neighboring cells in immediate environment of secretion site
2.Neurotransmitters
• Shortrange chemical messengers
• Diffuse across narrow space to act locally on adjoining target cell (another neuron, a muscle, or
a gland)
3.Hormones
• Longrange messengers
• Secreted into blood by endocrine glands in response to appropriate signal
• Exert effect on target cells some distance away from release site
We will see each of this one by one
The human body secretes and circulates some 50 different hormones. A wide variety of these
chemical substances are produced by endocrine cells, most of which are in glands. The hormones
then enter the blood system to circulate throughout the body and activate target cells. The
endocrine system, tightly linked to the nervous system, controls a large number of the body’s
functions: metabolism, homeostasis, growth, sexual activity, and contraction of the smooth and
cardiac muscles.
When a hormone diffuses outside of a capillary, it can act on a target cell – a cell with receptors
that correspond to it. There are two types of hormonal activity. A steroid hormone is capable of
crossing through the cell membrane of the target cell. It unites with a receptor protein located
inside the nucleus, which stimulates or blocks the cell’s genetic activity. A protein hormone, on
the other hand, cannot penetrate the target cell. It attaches to the cell’s membrane and activates a
receptor that releases, in turn, a messenger within the cell.
b) paracrines are proteins that are released from a secretory cell and travel through the plasma to
neighboring cells
In paracrine signaling, the signaling molecules released by a cell only affect target cells in close
proximity to it. The conduction of an electric impulse from one nerve cell to another or from a
nerve cell to a muscle cell (inducing or inhibiting muscle contraction) occurs via paracrine
signaling. The role of this type of signaling, mediated by neurotransmitters, in transmitting nerve
impulses.
Paracrine signaling is a form of cell-to-cell communication in which a cell produces a signal to
induce changes in nearby cells, altering the behavior or differentiation of those cells. Signaling
molecules known as paracrine factors diffuse over a relatively short distance (local action), as
opposed to endocrine factors (hormones which travel considerably longer distances via the
cir.
Which of the following is NOT a difference between the smooth ER and .pdfatulkapoor33
Which of the following is NOT a difference between the smooth ER and the rough ER? The
rough ER has ribosomes; the smooth ER does not. The smooth ER works to detoxify poisons;
the rough ER aren\'t got time for that. The smooth ER creates lipids while the rough ER makes a
lot of membrane proteins. The smooth ER makes phospholipids, but the rough ER does not. The
rough ER makes secretory proteins; the smooth ER does not.
Solution
The smooth ER are engaged in generation of lipids and phospholipids along with detoxification
of poisons from the cells. On the other hand, rough ER are engaged in genertion of proteins since
they carry ribosomes on their surface where translation takes place. Importantly, the rough ER
are involved only in generation of primary sequence of proteins i.e. a polypeptide sequence.
They do not help in folding or generation of secondary structure of proteins. Moreover, the
polypeptide synthesized on rough ER contains a leader seqeunce which helps the nascent
polypeptide to golgi apparatus for transport. This suggests that the rough ER are not involved in
generationof secretory protein.
Thus, this information suggests that choice E is correct..

westphalian order is about what? what are the human principle of westphalian? how westphalian
is underpressure of globalization?
Solution
i) Westphalian order: is the principle of international law that each nation state has sovereignty
over its territory and domestic affairs, to the exclusion of all external powers, on the principle of
non-interference in another country\'s domestic affairs, and that each state (no matter how large
or small) is equal in international law. As European influence spread across the globe, the
Westphalian principles, especially the concept of sovereign states, became central to
international law and to the prevailing world order.
ii) Collectively known as the Westphalian system, the principles are:
iii) During the 1980s and early 1990s, the imperative of globalization and interdependence led to
international integration, and the erosion of Westphalian sovereignty. The European Union\'s
concept of shared sovereignty is also somewhat contrary to historical views of Westphalian
sovereignty, as it provides for external agents to influence and interfere in the internal affairs of
its member countries..
Warren Delaney believed that his home was his “castle,” and during t.pdfatulkapoor33
Warren Delaney believed that his home was his “castle,” and during the summer months every
year, his “castle” was a tiny cabin nestled in the woods of upstate New York. Delaney was an
Economics professor at a small college in Florida, and for him, there was no better way to “rest
and recharge” after a hectic academic year than to head north for the cozy confines of his cabin.
For several consecutive years, Warren’s cabin had been vandalized and/or burglarized during
the winter months while he was in Florida. During the winter of 2006, several windows had been
shattered. In the winter of 2007, several pieces of furniture had been stolen. At some point during
the winter of 2008, the bedroom mattress had been ripped apart for some unexplained reason,
with foam and fabric scattered about the bedroom floor. On each of these occasions, the
perpetrator had forced the front door lock open, and had entered the cabin through the front door.
Warren envisioned a way to stop the criminal(s) responsible for these violations. He spring-
loaded a shotgun in the living room of the cabin, and pointed it directly at the front door. The
shotgun was configured so that if someone opened the front door while he was away, it would
fire at the intruder.
Warren returned to his cabin in May 2010 and came upon a grisly scene. The front door had
been opened, and at the threshold was the partially-decomposed body of what appeared to be a
middle-aged man, dead of a shotgun blast to the chest. Warren immediately called the local
sheriff, Officer Brian Mulholland. Upon arriving at the scene and briefly questioning Warren,
Officer Mulholland arrested him.
Was the arrest valid? Did Warren Delaney commit first-degree murder? Did Warren use
justifiable force in this situation?
Solution
Yes, the arrest was valid. This is a case of culpable homicide involving the illegal killing of a
person either with or without an intention to kill.
Here the person has died. The killing was unlawful, wilful and predetermined. It was a planned
murder. So it will be considered a first degree murder.
Justifiable force is use of force in defense, home protection, in defense of property. But the case
is that the force led to the person dying. Warren had planted the gun in such a way that the
intruder will be shot and killed. So the use of force is not justifiable..

This phenomenon is primarily responsible for the redistribution of he.pdfatulkapoor33
This phenomenon is primarily responsible for the redistribution of heat across the plant Coriolis
effect curvature of the Earth Adiabatic cooling Biome
Solution
The solar heat gained by our planet from the sun is not even. The uneven heat is redistributed
across the planet by air circulation, water vapour, ocean current, earth rotation. Due to uneven
heat the climate and weather patterns are maintained.
These are the following phenomenon primarily responsible for the redistribution of heat.
Coriolis effect: The Earth rotates once every 24 hours. Due to that rotation, the uneven heat
energy from the sun is redistributed by moving air masses, water vapor and ocean currents. This
effect is called coriolis effect.
Curvature of the earth causes uneven distribution of solar heat. Therefore the solar flux is
maximum at equator than the polars.
Adiabatic cooling is the process of reducing heat through a change in air pressure caused by
volume expansion. In nature when there is very hot, the air close to earth becomes lighten and
moves up and to fullfil that place cold heavy air comes. that results in redistribution of heat
across the earth..

Solution
14. B. Choanoflagelleates share common ancestry with animals.
Analysis of the combined data set (concatenated) along with sequences from other closely
related species (animals and fungi) demonstrate that choanoflagellates are strongly supported as
monophyletic and confirm their position as the closest known unicellular living relative of
animals.
15. B. Multicellular haplaid gamete producing organism.
Two single-celled haploid gametes, fuse to form a single-celled diploid zygote. The single-celled
diploid zygote germinates, dividing by the normal process (mitosis),The result is a multi-cellular
diploid organism, called thesporophyte(because at maturity it produces spores).
When it reaches maturity, the sporophyte produces one or moresporangia(singular: sporangium)
which are the organs that produce diploid spore mother cells (sporocytes). These divide by a
special process (meiosis) that reduces the number of chromosomes by a half. This initially results
in four single-celled haploid spores, each containingnunpaired chromosomes. The single-celled
haploid spore germinates, dividing by the normal process (mitosis), which maintains the number
of chromosomes at n. The result is a multi-cellular haploid organism, called
thegametophyte(because it produces gametes at maturity).
16. B. Haploid, gametes.

Multiple choice Which Protozoa phyla is responsible for red tides an.pdfatulkapoor33
Multiple choice: Which Protozoa phyla is responsible for red tides and can be toxic?
Euglenozoa Trypanosomatidea Ciliophora Dinozoa Multiple choice: Which class of Cnidarians
includes corals and anemones? Hydrozoa Scyphozoa Cubozoa Anthozoa Multiple choice:
Adhesive cells in Ctenophores are called: Cnidocysts Nematocystes Nerve net Colloblasts
Solution
Please find the answers below and explanations in parentheses:
Answer 7: Choice 4 (red tide is a phenomenon observed by presence of large amount of algal
blooms in sea with appearance of red coloration of water. These algal blooms are basically
dinoflagellates by nature with colored cell coatings in reddish appearance. Together, these
phytoplanktons give appearance of large red-tides in the sea and are termed as Red tide)
Answer 8: Choice 4 (the class anthozoa of cnidarian organisms include the forms which make up
sedenatry life-style such as corals and sea anemones. They are always sedentary in nature but
produce motile sperms which can perform sexual reproduction. Examples include sea anemone,
Montastraea cavernosa, the corals of the great Australian coral reef etc.)
Answer 9: Choice 4 (Colloblasts are small unique cells distributed in the tentacles of the
ctenophora which help in attaching to the substratum and also help in capturing the prey. They
contain digestive tentacles and sometimes eosinophilic cells inside them which penetrate through
the substrate/prey and help in attaching to them.Thus, colloblasts are the functional cells of
cnidarians for capturing prey).

Mainly stuck on why this is not readily available and used in the United States. EcoCute is a
transcritical CO2 heat pump used extensively in Europe and Japan. Investigate this technology
and compare its operational schematic and accompanying T s diagram with that shown in Fig.
10.18. Explore why this technology is not readily available and used within the United States.
Compare its use for a 1000 ft2 dwelling in your locale with a more conventional air-cooled
residential heat pump using a synthetic refrigerant in terms of costs (operational and
environmental impact. What are the impediments to its deployment in the United initial) and
States? Create a PowerPoint presentation of your findings and a supporting project report
Solution
To specifically answer your question, a transcritical CO2 heat pump uses C02 or R744 as the
natural refrigerant which has the following the implications in terms of its behaviour:
1. It combines with water in air to form carbonic acid which has corrosive properties over metal
and can damage limestone and marble.
2.Breathing air that has even ~10% of Co2 content can prove life threatening.
3. R744 is one and a half times heavier than air therefore when released to air, it will accumilate
at low elevations .
As far as its use in the United States is concerned, there are legal liabilities over the long term for
the manufactureres of Co2 heat pumps. Hence it is not readily available as compared to Japan
and Europe..
Java ProgrammingImplement an auction application with the followin.pdfatulkapoor33
Java Programming
Implement an auction application with the following features/functionality:
Inputs for an item and minimum bid amount.
Inputs for bidder name, bid amount and maximum bid. You will implement a class called Bid to
hold this information.
Label controls to show the current high bidder’s name, bid amount and maximum bid. For bid
amounts, you may assume all bids will be a whole dollar value just to simplify things a bit.
A list box to show all entries when the auction is over. You will use the pop() method to retrieve
each bid off the stack and display it. This feature is intended more for test/debug purposes.
You will implement a Stack class that will keep the highest bid at the top of the stack. It must
have the classic stack operations of push() to place an item on the stack, pop() to remove the top
item from the stack, and top() to view the top item on the stack but not remove it. You may use a
linked list of your own design, an array, or the built-in Java Array List or Linked List classes as
the underlying data structure. You may also add an item count property if you want.
The auction will work by the following rules:
When the initial bid is made, it must be greater than or equal to the item’s minimum bid amount
to be placed on the stack.
When another bid is made that is greater than the current high bidder’s maximum bid, that bid
will be pushed to the top of the stack and become the new highest bid.
If another bid is made that is greater than the current high bid but less than or equal to the
current high bidder’s maximum amount, the current high bidder’s bid will be raised to match but
the new bid will not be placed on the stack.
Your application should have a message box or label to indicate the status of the bid operation.
There is no limit on the number of bids.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Consider the incompressible and irrotational flow around a Rankine h.pdf
1. Consider the incompressible and irrotational flow around a Rankine half-body... Consider the
incompressible and irrotational flow around a Rankine half-body (cf. Figure 1). The flow can be
modeled using the superposition of a source at point (a. b) and a uniform flow in the redirection.
Suppose that we would like to model the flow around a halfbody that is inclined (relative to the
horizontal) at an angle alpha (i.e. it is rotated CCW by an angle alpha). Find the velocity
potential function Psi for the inclined half-body in terms of x and y coordinates. Find the stream
function Phi for the inclined half-body in terms of x and y coordinates. Utilizing your answer to
part (a), find expressions for the velocity components u and v. Utilizing your answer to part (b).
find expressions for the velocity components u and v. Show that the Laplacian of Psi is equal to
zero. Show that the Laplacian of Phi is equal to zero. Find an expression for the pressure
coefficient that is valid for all points in the flow. Neglect gravitational forces, and assume that
Bernoulli's equation applies.
