JAVA A double-ended queue is a list that allows the addition and.pdf
**JAVA** A double-ended queue is a list that allows the addition and removal of items from
either end. One end is arbitrarily called the front and other the rear, but the two ends behave
identically. Specify, design and implement a class for a double-ended queue. Include operations
to check if it is empty and to return the number of items in the list. For each end, include
operations for adding and deleting items. Use doubly linked list for your implementation. Call
your class Deque (pronounced \"deck\").

Let f(z) be an entire function such that fn+1(z) equivalent 0, Prove.pdf
Let f(z) be an entire function such that fn+1(z) equivalent 0, Prove that f is a polynomial of
degree at most n?
Solution
We can prove the above formula using mathematical induction.
So lets us take multiple cases.
For f(x) = x, f(x)\'=1, f(x)\'\'=0. so for f(x)^2 the polynomial power is 1,
for f(x)=x^2, f(x)\'=2x, f(x)\'\'=2, f(x)\'\'\'=0, so for f(x)\'\'\' the polynomial is 2.
So we can deduce that for a polynomial with n power it should be differentiated n+1 times to get
fn+1(z)=0,
So it could be stated otherwise if fn+1(z)=0 then f(z) has a power of atmost x^n..

How are the forelimbs of humans, the wings of birds, the wings of ba.pdf
How are the forelimbs of humans, the wings of birds, the wings of bats, the wings of insects
similar, how are they different, and what do we think happened in the past evolution of these
structures ?
Solution
All these structures mentioned, that is, the forelimbs of humans, the wings of birds, the wings of
bats, the wings of insects have a similarfunction because they all are used for movement. But
they are structurally very dissimilar. Hence they are also known as analogous characters.
The independent evolution of characters in members of different species with similar function
but differences in structure and ancestral origin is known as convergent evolution. This type of
evolution leads to the formation of analogous characters or traits. The convergent evolution of
flight of birds, bats and insects is known as functional convergence, as their function is similar.
In the very past, there must have been a common ancestor, from whom the wings and forelimbs
were evolved and structurally became different in the course of evolution..

Germ cells are set aside during animal development and give rise to .pdf
Germ cells are set aside during animal development and give rise to the gonads during
embryogensis. Discuss the implications of this with regards to inheritance of the genetic
mutations inherited from a parent vs. mutations acquired during the lifespan of the organism.
Solution
Inheritance of the genetic mutations inherited from a parent:
Genetic mutations inherited from a parent are also called germline mutations because they are
present in the parent’s germ cells i.e. their egg or sperm cells. These cells give rise to the gonads
during embryogenesis. When embryogenesis takes place the resulting fertilized egg cell receives
DNA from both parents. The mutated germ cells thus result in formation of mutated DNA
making it an inherited mutation.
Mutations acquired during the lifespan of the organism:
When mutation takes place during lifespan and in some cells of the body, it results in acquired
mutation. These can be caused by environmental factors such as ultraviolet radiation from the
sun, or can occur if a mistake in DNA copieng during cell division. Acquired mutations takes
place in somatic cells which are other than the germ cells. Such mutations which are not
inherited do not take place in germ cells..

Discuss the various methods of intellectual property protection available to businesses and
individuals.
Solution
The World Trade organisation (WTO) divides intellectual property in two main areas:
(i) Copyright and rights related to copyright. back to top
The rights authors have over literary and artistic works of their creation (such as books and other
types of creations, like paintings, sculpture, computer programs, music and films), are protected
by copyright, for a minimum time of 50 years after the author’s death.
Also are protected by copyright (neighbouring) the rights of performers such as actors, singers,
musicians, producers of phongrams and broadcasting agencies. The main purpose of copyright
laws is to protect and encourage authors and creators to keep working on their artistic and
creative products, having a legal base to cover them as owners of their work.
Industrial property
Industrial property is divided in two areas:
Industrial property is protected by law so as to encourage inventors, technology creators in all
areas to do their work, and to ensure they are the owners of their own work and gained

by evidence would support the theory of evolution. Devise a hypothesis that explains the
geographical distribution of modern species, that is backed by evidence would refute the theory
of evolution. regarding chapter 22 descent with modification campbell 10ed
Solution
One of the difficulties in knowledge the ecological basis for species range distributions is
knowing the general significance of abiotic factors like temperature, precipitation, topography, or
earth situations (i.e., bioclimatic or potential niche) vs. biotic interactions among species like
predation, opposition or mutualisms (biotic or noticed niche) in deciding wherever species can be
found geographically. Moreover, if weather change stands to improve species geographic
locations, we however don\'t know if their biotic interdependencies, established by their
interactions, will become unravelled called community disassembly or if community can transfer
as intact units. Modern analyses of species geographic range distributions concentration on
bioclimatic niches, with restricted work to think about biotic interactions.
Classically there were two hypotheses for the progress of humans, the multiregional hypothesis -
modern Homo sapiens evolved simultaneously for the duration of the old world from archaic
Homo sapiens Homo sapiens with exchange of with exchange of genetic data by gene flow and
the out-of-Africa hypothesis - modern humans evolved in Africa and transferred out changing
previously widely dispersed archaic humans. The newest kind, the modern horse (Equus), is a lot
larger in size, is one-toed, and has teeth appropriate for grazing. The transitional forms are well
preserved as fossils, as are a great many other types of extinct horses that evolved in different
directions and remaining no living descendants..

Consider managers (supervisors) that you have worked for in the past.pdf
Consider managers (supervisors) that you have worked for in the past. What type of power did
they have? Was it effective?
Must be a good sized paragraph and site information
Solution
earlier i worked with 2 different kind of people who were my bosses. the previous one is Naveen,
HOD of management studies in the college. he is a consultative manager, he recieves the targets
and orders from the top level people and once he recieves the orders he called all of us and ask
how to implement and what are the limitations and possibilities. here he have the ultimate power
to do it and implement it. and some times he distributes the work along with power to others and
they work in their own limitations.
when ever he feels that if any activity involves much risk, then he used to call top level people
and explain them about the consequences and the decision of them. if they ask to proceed he can
move forward otherwilse they rethinks about the task and re-assign it by doing some
modifications.
the power has been enjoying by him is given by the position (HOD) and he is the answerable
person to the higher authorities. he is the whole responsible person to the failures and even for
success also. yes, it was effective and it makes sense. ofcourse some times it leads to delay the
work and once a while fail also..

Discuss the following questions briefly
1.In the 1980s a stronger dollar hurt Caterpillars competitive position, but in 2008 a stronger
dollar did not seem to have the same effect. What had changed?
2. How did Caterpillar use strategy as a \"real hudge\" to reduce its exposure to foreign exchange
risk? What is the downside of its its approach?
3. Explain the difference between transaction exposure and translation exposure using the
material in the Caterpillar case to illustrate your answer.
Solution
1.In the 1980s a stronger dollar hurt Caterpillars competitive position, but in 2008 a stronger
dollar did not seem to have the same effect. What had changed?
Confidence in US Assets: The dollar started to strengthen again in 2008, foreing investment in
US assests was strong, Treasury bills was safe haven in economic stom
Deal with Unions: in the 80´s : employee layoffs and striks, outsourcing parts of production .
Mid 2000s: reached deal with union, increase of productivity.
Change in company structure: Centralized to decentralized, own pricing decisions, own product
desings, improved quality and efficiency
Improvement in product technology & energy efficiency.
2. How did Caterpillar use strategy as a \"real hudge\" to reduce its exposure to foreign exchange
risk? What is the downside of its its approach?
Caterpillar´s global foot print: \"From Calgary to Cairo and from Sydney to Salt Lake city
Caterpillar operates hundreds of offices and facilitites across the world. Caterpillar´s global
presence, product breadth and financial strenght enable us wo tin in today´s competitive market
place.
Forward Exchange: When 2 parties agree to exchange and execute the deal at some specific date
in the future.
Downside of its approach:
Currency´s value is determinated by market force, government intervention as well as demand
and supply of currency:
Globalisation: More competition within the global market that have adopted globalisation
Forward Exchange: Based on future expectation of the foreign exchange market
3. Explain the difference between transaction exposure and translation exposure using the
material in the Caterpillar case to illustrate your answer.
Transaction Exposure: The extent to which income from invididual transactions is affected by
fluctuation in foreign exchange valus
1980´s
Us dollar strenfthens
Foreign payable to Caterpillar become more expensive
Loss of foreign sales = reduced revenues + Limited means of managing transaction exposure =
Massive reduction in future cash flows
Translation Exposure: The extent to which consolidated financial results of a corporation are
affected by movements in exchange rates.

What are the three forms of Business Organizations Answer the follow.pdf
What are the three forms of Business Organizations? Answer the following Accounts: (A)Asset
(L)Liability (SE)Stockholders\' Equity 1. Cash 2. Common Stock 3. Accounts Payable 4. Rent
Expense 5. Sales or Revenue 6. Accounts Receivable What is the first financial statement to be
prepared? What are the three Activities of a Business? Financial Accounting provides
information for decision makers primarily inside or outside the entity? What are the Rules of
Accounting called? Write the Accounting Equation? Can it be written another way?
Solution
The three forms of business organizations are Sole proprietorship, Partnership, and a
Corporation.
1. Cash – (A)
2. Common stock – (SE)
3. Accounts payable – (L)
4. Rent expense – (SE)
5. Sales or Revenue – (SE)
6. Accounts receivable – (A)
The first financial statement to be prepared is the Income Statement.
The three activities of a business are Operating activities, Investing activities, and Financing
activities.
Financial Accounting provides information for decision makers primarily outside the entity such
as shareholders, creditors, etc.
The Rules of Accounting are called the Generally Accepted Accounting Principles or GAAP for
short.
The Accounting Equation is typically written as:
Assets = Liabilities + Stockholders’ Equity
It can also be written in two more ways as under:
Liabilities = Assets – Stockholders’ Equity; or
Stockholders’ Equity = Assets - Liabilities.
Anatomy Question Use your own words.A girl with a defective heart.pdf
Anatomy Question: Use your own words.
A girl with a defective heart receives a new heart transplanted from another child who was killed
in an accident. The patient is given an antilymphocyte serum containing antibodies against her
lymphocytes. The transplanted heart is not rejected, but the patient dies of an overwhelming
bacterial infection. Why was the antilymphocyte serum given? Why was the patient so
vulnerable to infection?
Solution
Ans: antilymphocyte serum is given or suppress immune response to stop graft rejection as the
heart received is not matched with receiver due to different HLA or MHC on the donor and
recepient tissues. So that heart I.e allograft can\'t be rejected by host immune system.
But here comes a problem I.e host immune system is compromised due to antilymphocyte
serum,so no longer host immune system can fight against disease.so host is more prone to
diseases and soon dies.

Which statement is not true promoters are transcribed the Pribnow .pdf
Which statement is not true? promoters are transcribed the Pribnow box found in bacteria,
consists of TATAAT Enhancers are DNA sequences exons are spliced activators are proteins
Solution
Promoters are transcribed
This statement is false because promoters are regions which binds to transcription factors that
initiate transcription upstream. Thus they are the regions that regulate the transcription but itself
is not transcribed.
Exons are spliced
The above sequence is correct because in alternative splicing some exons may be included and
some are spliced to generate multiple RNA from single DNA sequence.
Hence option A is correct..

might undergo annealing (happens in PCR).
Which ANN do you prefer amidst of the variety of ANNs Justify the r.pdf
Which ANN do you prefer amidst of the variety of ANNs? Justify the reason beyond this.
Solution
Recurrent neural network are the best type of Artificial neural network among various other
varieties of ANN (Feedforward neural network , Radial basis function (RBF) network , Kohonen
self-organizing network , Learning vector quantization , Modular neural networks , Physical
neural network).
Reason:
1) Recurrent neural network allows bi-directional data flow from Input source to Output
Destination and vice versa.While on the other hand, other networks like Feedforward neural
network propagates data linearly from input to output.
2) Connections are symmetric in Recurrent neural network and also it demonstrate learning of
latent variables..

Life story analysis examines people's life histories through interviews to understand their unique experiences and common themes. The life story interview involves a collaborative process between the interviewer and interviewee to construct a narrative account. These life stories are then evaluated not based on factual accuracy but how people use accounts of their lives. Analyzing life stories highlights important influences, relationships, and life themes while also acknowledging personal perspectives and narratives.
What could be the genotype of the parents who have a. Two kids one o.pdf
What could be the genotype of the parents who have a. Two kids one of which is tongue roller
and the bitter taster (homozygous for both traits) and the other is a non-roller and non-taster.
Note, both abilities are dominant traits b. Two kids, both of which are non-rollers and non-
tasters.
Solution
Answer:
(a) Since one of the kids is a non-roller and non-taster (homozygous recessive, bbrr) and the
other is homozygous dominant (BBRR), the genotypes of the parents should be heterozygous
dominant (BbRr).
Crossing BbRr * BbRr, we get (in F1)
Proportion of BBRR = 1 / 16 and bbrr = 1 / 16
(b) Both the kids are non-rollers and non-tasters. So, both are homozygous recessive for the
traits. The genotypes of each parents should contain atleast one recessive allele for each trait.
Therefore, the genotype of the parents are:
- b - r and - b - r.

two different ways the turbine blade is protected from oxygen during manufacturing.
Solution
[1] Direct Chemical Attack or Chemical or Dry Corrosion
Whenever corrosion takes place by direct chemical attack by gases like\' oxygen, nitrogen and
halogens, a solid film of the corrosion product is formed on the surface of the metal which
protects
the metal from further corrosion. If a soluble or volatile corrosion product is formed, then the
metal
is exposed to further attack. For example, chlorine and iodine attack silver generating a
protective
film of silver halide on the surface. On the other hand, stannic chloride formed on tin is volatile
and
so corrosion is not prevented.
Oxidation corrosion is brought about by direct action of oxygen at low or high temperatures
on metals in the absence of moisture. Alkali metals (Li, Na, K, etc.) and alkaline earth metals
(Mg, Ca, Sn, etc.) are readily oxidized at low temperatures. At high temperatures, almost all
metals
except Ag, Au and Pt are oxidized. Alkali and alkaline earth metals on oxidation produce oxide
deposits of smaller volume. This results in the formation of a porous layer through which
oxygen can
diffuse to bring about further attack of the metal. On the other hand, aluminium, tungsten and
molybdenum form oxide layers of greater volume than the metal from which they were
produced.
These non-porous, continuous and coherent oxide films prevent the diffusion of oxygen and
hence the rate of further attack decreases with increase in the thickness of the oxide film.
The protective or non-protective nature of the oxide film is determined by a rule known as the
Pilling-Bedworth rule. The ratio of the volume of the oxide formed to the volume of the metal
consumed is called the Pilling-Bedworth rule. According to it, if the volume of the oxide layer is
greater than the volume of the metal, the oxide layer is protective and non-porous. On the other
hand,
if the volume of the oxide layer formed is less than the volume of the metal, the oxide layer is
non
protective and porous.
[2] Electrochemical Theory or Wet Corrosion
According to the electrochemical theory, the corrosion of a metal in aqueous solution may be
a two-step process, one involving oxidation and another reduction. It is known that two metals
having different electrode potentials form a galvanic cell when they are immersed in a
conducting
solution. The emf of the cell is given by the difference between the electrode potentials.
When the electrodes are joined by a wire, electrons flow from the anode to the cathode.
The oxidation reaction occurs at the anode, i.e. at the anode the metal atoms lose their electrons
to
the environment and pass into the solution in the form of positive ions.
Fe Fe2+ + 2e-
3
Thus, there is a tendency at the anode to destroy the metal by dissolving it as ions. Hence
corrosion always occurs at anodic areas.
The electrons released at the anode are conducted to the cathode and are responsible for
various cathodic rea.
The final answer is supposed to be about 2 increase Name Page 2 of.pdf
The final answer is supposed to be about 2% increase Name: Page 2 of 8 l attest that the work
shown on this quiz is entirely my own, and was done without the aid of unauthorized materials
such as the internet, in accordance with the University of Pittsburgh at Johnstown\'s Academic
Integrity Policy 2. In 2012, the population of a country was 65 million and the projected
exponential rate of increase is 5.2 per l ,000. If the environmental impact per GDP is reduced by
15% by 2040, how will this affect the GDP per capi maintained at the 2010 levels? ta assuming
the total environmental impact in 2040 is CE 1610: Engineering and Sustainable Development
Solution
I = PAT
dI/dt = dP/dT + dA/dt+ dT/dt
We are keeping technology constant,
Population changes by 5.2 every year P = P0 x ert = 65 x 2.728 x 0.0052 = 75.11 million
Change in population % = 15.55%
Change in environmental impact per capita GDP = -15% i.e Change in GDP/change in
population = -15%
x/15.55 = - 0.15 ; x = -2.3325%.

Consider managers (supervisors) that you have worked for in the past.pdf
Consider managers (supervisors) that you have worked for in the past. What type of power did
they have? Was it effective?
Must be a good sized paragraph and site information
Solution
earlier i worked with 2 different kind of people who were my bosses. the previous one is Naveen,
HOD of management studies in the college. he is a consultative manager, he recieves the targets
and orders from the top level people and once he recieves the orders he called all of us and ask
how to implement and what are the limitations and possibilities. here he have the ultimate power
to do it and implement it. and some times he distributes the work along with power to others and
they work in their own limitations.
when ever he feels that if any activity involves much risk, then he used to call top level people
and explain them about the consequences and the decision of them. if they ask to proceed he can
move forward otherwilse they rethinks about the task and re-assign it by doing some
modifications.
the power has been enjoying by him is given by the position (HOD) and he is the answerable
person to the higher authorities. he is the whole responsible person to the failures and even for
success also. yes, it was effective and it makes sense. ofcourse some times it leads to delay the
work and once a while fail also..
Caterpillar is one of the Americas major exporters. The company sell.pdf
Caterpillar is one of the Americas major exporters. The company sells its construction
equipment, mining, equipment and engines to some 200 contries.
Discuss the following questions briefly
1.In the 1980s a stronger dollar hurt Caterpillars competitive position, but in 2008 a stronger
dollar did not seem to have the same effect. What had changed?
2. How did Caterpillar use strategy as a \"real hudge\" to reduce its exposure to foreign exchange
risk? What is the downside of its its approach?
3. Explain the difference between transaction exposure and translation exposure using the
material in the Caterpillar case to illustrate your answer.
Solution
1.In the 1980s a stronger dollar hurt Caterpillars competitive position, but in 2008 a stronger
dollar did not seem to have the same effect. What had changed?
Confidence in US Assets: The dollar started to strengthen again in 2008, foreing investment in
US assests was strong, Treasury bills was safe haven in economic stom
Deal with Unions: in the 80´s : employee layoffs and striks, outsourcing parts of production .
Mid 2000s: reached deal with union, increase of productivity.
Change in company structure: Centralized to decentralized, own pricing decisions, own product
desings, improved quality and efficiency
Improvement in product technology & energy efficiency.
2. How did Caterpillar use strategy as a \"real hudge\" to reduce its exposure to foreign exchange
risk? What is the downside of its its approach?
Caterpillar´s global foot print: \"From Calgary to Cairo and from Sydney to Salt Lake city
Caterpillar operates hundreds of offices and facilitites across the world. Caterpillar´s global
presence, product breadth and financial strenght enable us wo tin in today´s competitive market
place.
Forward Exchange: When 2 parties agree to exchange and execute the deal at some specific date
in the future.
Downside of its approach:
Currency´s value is determinated by market force, government intervention as well as demand
and supply of currency:
Globalisation: More competition within the global market that have adopted globalisation
Forward Exchange: Based on future expectation of the foreign exchange market
3. Explain the difference between transaction exposure and translation exposure using the
material in the Caterpillar case to illustrate your answer.
Transaction Exposure: The extent to which income from invididual transactions is affected by
fluctuation in foreign exchange valus
1980´s
Us dollar strenfthens
Foreign payable to Caterpillar become more expensive
Loss of foreign sales = reduced revenues + Limited means of managing transaction exposure =
Massive reduction in future cash flows
Translation Exposure: The extent to which consolidated financial results of a corporation are
affected by movements in exchange rates.

What are the three forms of Business Organizations Answer the follow.pdf
What are the three forms of Business Organizations? Answer the following Accounts: (A)Asset
(L)Liability (SE)Stockholders\' Equity 1. Cash 2. Common Stock 3. Accounts Payable 4. Rent
Expense 5. Sales or Revenue 6. Accounts Receivable What is the first financial statement to be
prepared? What are the three Activities of a Business? Financial Accounting provides
information for decision makers primarily inside or outside the entity? What are the Rules of
Accounting called? Write the Accounting Equation? Can it be written another way?
Solution
The three forms of business organizations are Sole proprietorship, Partnership, and a
Corporation.
1. Cash – (A)
2. Common stock – (SE)
3. Accounts payable – (L)
4. Rent expense – (SE)
5. Sales or Revenue – (SE)
6. Accounts receivable – (A)
The first financial statement to be prepared is the Income Statement.
The three activities of a business are Operating activities, Investing activities, and Financing
activities.
Financial Accounting provides information for decision makers primarily outside the entity such
as shareholders, creditors, etc.
The Rules of Accounting are called the Generally Accepted Accounting Principles or GAAP for
short.
The Accounting Equation is typically written as:
Assets = Liabilities + Stockholders’ Equity
It can also be written in two more ways as under:
Liabilities = Assets – Stockholders’ Equity; or
Stockholders’ Equity = Assets - Liabilities.
Anatomy Question Use your own words.A girl with a defective heart.pdf
Anatomy Question: Use your own words.
A girl with a defective heart receives a new heart transplanted from another child who was killed
in an accident. The patient is given an antilymphocyte serum containing antibodies against her
lymphocytes. The transplanted heart is not rejected, but the patient dies of an overwhelming
bacterial infection. Why was the antilymphocyte serum given? Why was the patient so
vulnerable to infection?
Solution
Ans: antilymphocyte serum is given or suppress immune response to stop graft rejection as the
heart received is not matched with receiver due to different HLA or MHC on the donor and
recepient tissues. So that heart I.e allograft can\'t be rejected by host immune system.
But here comes a problem I.e host immune system is compromised due to antilymphocyte
serum,so no longer host immune system can fight against disease.so host is more prone to
diseases and soon dies.

Which statement is not true promoters are transcribed the Pribnow .pdf
Which statement is not true? promoters are transcribed the Pribnow box found in bacteria,
consists of TATAAT Enhancers are DNA sequences exons are spliced activators are proteins
Solution
Promoters are transcribed
This statement is false because promoters are regions which binds to transcription factors that
initiate transcription upstream. Thus they are the regions that regulate the transcription but itself
is not transcribed.
Exons are spliced
The above sequence is correct because in alternative splicing some exons may be included and
some are spliced to generate multiple RNA from single DNA sequence.
Hence option A is correct..

When extracting DNA of an fruit how does the environemnt (how hot or cold the onion is) affect
the DNA?
Solution
The temperature of the extraction will determine the working of the enzymatic systems (internal
and external). As increasing the temperature will hamper the the enzymes, further the DNA
might undergo annealing (happens in PCR).
Which ANN do you prefer amidst of the variety of ANNs Justify the r.pdf
Which ANN do you prefer amidst of the variety of ANNs? Justify the reason beyond this.
Solution
Recurrent neural network are the best type of Artificial neural network among various other
varieties of ANN (Feedforward neural network , Radial basis function (RBF) network , Kohonen
self-organizing network , Learning vector quantization , Modular neural networks , Physical
neural network).
Reason:
1) Recurrent neural network allows bi-directional data flow from Input source to Output
Destination and vice versa.While on the other hand, other networks like Feedforward neural
network propagates data linearly from input to output.
2) Connections are symmetric in Recurrent neural network and also it demonstrate learning of
latent variables..

what is life story analysisSolutionThe life history has l.pdf
Life story analysis examines people's life histories through interviews to understand their unique experiences and common themes. The life story interview involves a collaborative process between the interviewer and interviewee to construct a narrative account. These life stories are then evaluated not based on factual accuracy but how people use accounts of their lives. Analyzing life stories highlights important influences, relationships, and life themes while also acknowledging personal perspectives and narratives.
What could be the genotype of the parents who have a. Two kids one o.pdf
What could be the genotype of the parents who have a. Two kids one of which is tongue roller
and the bitter taster (homozygous for both traits) and the other is a non-roller and non-taster.
Note, both abilities are dominant traits b. Two kids, both of which are non-rollers and non-
tasters.
Solution
Answer:
(a) Since one of the kids is a non-roller and non-taster (homozygous recessive, bbrr) and the
other is homozygous dominant (BBRR), the genotypes of the parents should be heterozygous
dominant (BbRr).
Crossing BbRr * BbRr, we get (in F1)
Proportion of BBRR = 1 / 16 and bbrr = 1 / 16
(b) Both the kids are non-rollers and non-tasters. So, both are homozygous recessive for the
traits. The genotypes of each parents should contain atleast one recessive allele for each trait.
Therefore, the genotype of the parents are:
- b - r and - b - r.

Use the Intermediate Value Theorem to show that there is a root of the equation in the given
interval. cos = ex - 2, (0, 1)
Solution
f(x)= cos x -e^x +2
f(0)= 2
f(1)= -0.18
Since the function is continuous in the interval and changes signs the intermediate value
theormem says there will be a root in the interval..
two different ways the turbine blade is protected from oxygen during.pdf
two different ways the turbine blade is protected from oxygen during manufacturing.
Solution
[1] Direct Chemical Attack or Chemical or Dry Corrosion
Whenever corrosion takes place by direct chemical attack by gases like\' oxygen, nitrogen and
halogens, a solid film of the corrosion product is formed on the surface of the metal which
protects
the metal from further corrosion. If a soluble or volatile corrosion product is formed, then the
metal
is exposed to further attack. For example, chlorine and iodine attack silver generating a
protective
film of silver halide on the surface. On the other hand, stannic chloride formed on tin is volatile
and
so corrosion is not prevented.
Oxidation corrosion is brought about by direct action of oxygen at low or high temperatures
on metals in the absence of moisture. Alkali metals (Li, Na, K, etc.) and alkaline earth metals
(Mg, Ca, Sn, etc.) are readily oxidized at low temperatures. At high temperatures, almost all
metals
except Ag, Au and Pt are oxidized. Alkali and alkaline earth metals on oxidation produce oxide
deposits of smaller volume. This results in the formation of a porous layer through which
oxygen can
diffuse to bring about further attack of the metal. On the other hand, aluminium, tungsten and
molybdenum form oxide layers of greater volume than the metal from which they were
produced.
These non-porous, continuous and coherent oxide films prevent the diffusion of oxygen and
hence the rate of further attack decreases with increase in the thickness of the oxide film.
The protective or non-protective nature of the oxide film is determined by a rule known as the
Pilling-Bedworth rule. The ratio of the volume of the oxide formed to the volume of the metal
consumed is called the Pilling-Bedworth rule. According to it, if the volume of the oxide layer is
greater than the volume of the metal, the oxide layer is protective and non-porous. On the other
hand,
if the volume of the oxide layer formed is less than the volume of the metal, the oxide layer is
non
protective and porous.
[2] Electrochemical Theory or Wet Corrosion
According to the electrochemical theory, the corrosion of a metal in aqueous solution may be
a two-step process, one involving oxidation and another reduction. It is known that two metals
having different electrode potentials form a galvanic cell when they are immersed in a
conducting
solution. The emf of the cell is given by the difference between the electrode potentials.
When the electrodes are joined by a wire, electrons flow from the anode to the cathode.
The oxidation reaction occurs at the anode, i.e. at the anode the metal atoms lose their electrons
to
the environment and pass into the solution in the form of positive ions.
Fe Fe2+ + 2e-
3
Thus, there is a tendency at the anode to destroy the metal by dissolving it as ions. Hence
corrosion always occurs at anodic areas.
The electrons released at the anode are conducted to the cathode and are responsible for
various cathodic rea.
The final answer is supposed to be about 2 increase Name Page 2 of.pdf
The final answer is supposed to be about 2% increase Name: Page 2 of 8 l attest that the work
shown on this quiz is entirely my own, and was done without the aid of unauthorized materials
such as the internet, in accordance with the University of Pittsburgh at Johnstown\'s Academic
Integrity Policy 2. In 2012, the population of a country was 65 million and the projected
exponential rate of increase is 5.2 per l ,000. If the environmental impact per GDP is reduced by
15% by 2040, how will this affect the GDP per capi maintained at the 2010 levels? ta assuming
the total environmental impact in 2040 is CE 1610: Engineering and Sustainable Development
Solution
I = PAT
dI/dt = dP/dT + dA/dt+ dT/dt
We are keeping technology constant,
Population changes by 5.2 every year P = P0 x ert = 65 x 2.728 x 0.0052 = 75.11 million
Change in population % = 15.55%
Change in environmental impact per capita GDP = -15% i.e Change in GDP/change in
population = -15%
x/15.55 = - 0.15 ; x = -2.3325%.
