Describe what is happening in Italy (or you may substitute Argentina or Iran) and how that might impact things like exchange rates, inflation and/or interest rates. Solution Let we take example of Iran, As we all know that USA has put a number of sanctions on Iran due to which trade with Iran is difficult, Country like India which Import a major portion of its crue oil import from Iran, now after these sanctions, India could not buy crude oil from Iran and this will also happen with other countries too. So this types of sanctions will force Countries like India to look for another partner for Oil import and this will have impact on its currency exchange rates as other oil exporting countries may demand different price for the crude oil. on other hand after so many sanctions Supply of curde oil will increase and prices may also increases which will result in more pressure on countries and this will have impact on exchange rate and when prices of crude oil will increase it will impact economy and inflation will also increase and general price level will also increase..

Our best evidence to data suggests that the Earth formed 4.6 billion .pdf
Our best evidence to data suggests that the Earth formed 4.6 billion years ago. What life forms
existed on Earth during the following periods. (Match the correct answer to each question; you
may use each answer more than once.) What happened during the first billion years (4.5-3.6
billion years ago)? What happened during the second billion years (3.6-2.6 billion years ago)?
What happened during the third billion years (2.6-1.6 billion years ago)? What happened during
the third billion years (2.6-1.6 billion years ago)? What happened during the fourth billion years
(1.6-0.6 billion years ago)? What happened during the last 600 million years (0.6 billion years
ago to present)? A. no life existed B. unicellular life appeared C. unicellular life forms were the
only living things on Earth d. multicellular life appeared. E. dinosaurs dominated the entire
period F. mammals dominated the entire period
Solution
What happened during the first billion years? (4.6 -3.6 billion years ago?) A. no life existed.
Reason: Earth was formed over 4.6 billion years ago.Before that there was no life.
What happened during the second billion years? (3.6 -2.6 billion years ago?) C.Unicellular life
forms were the only living things on earth.
Reason:Unicellular life appeared first about 3.6 billion years ago.
What happened during the third billion years? (2.6-1.6 billion years ago?) B.unicellular life
appeared.
Reason:Unicellualr life appeared on earth during this period.
What happened during the fourth billion years? (1.6 -0.6 billion years ago?) D.multicellular life
appeared.
Reason:Multicellular life appeared 1.5 billion years ago.
What happened during the last 600 million years (0.6 billion years ago to pesent?) E and F.

one human resource manager recently got a thank you note on her iPho.pdf
one human resource manager recently got a thank you note on her iPhone that said “Thx 4 the
Iview! Wud to wrk 4 u!!!” The manager had liked the candidate’s interview, but after getting the
note, she put him in the reject pile. Do you think it was fair for the manager to automatically
reject the candidate? Should “textspeak” be considered acceptable workplace communication?
Discuss.
Solution
as per the above explanation we can not say that what the manager has did and because of the
text mail only he rejected the candidate. and some times it may not possible to select the
candidate even he did best in the interview. there would some one else who performed best than
the other. in those times, he may reject the good one to choose the best.
and based on the above explanation it can be observed that the interviwer is a lady and the
interviewee is a gent or boy. she may not like expressing his ability and interest to work in the
firm. and she have not decided and discolsed it to the guy that he is selected or rejected. she may
put it hold and mean while by looking at his message she may refused the application.
but, because of the only message if she rejected him, it is not fair..
Mutations rII1 and rII2 are known to fall into the rIIA and rIIB cis.pdf
Mutations rII1 and rII2 are known to fall into the rIIA and rIIB cistrons (genes) respectively.
Mutations rII1 and rII2 are used to infect E. coli B at very low multiplicity of infection (m.o.i.)
and the progeny phage collected. These phage are then used to infect strain K at very low m.o.i..
The resulting phage are diluted and plated on both E. coli B and E. coli K. Do you expect more
plaques on strain B, on Strain K, an equal amount on both or is it impossible to tell? Explain
Solution
Strain B have more plaques because it supports the growth of all viruses,wild type T4 as well as
rII mutants which are able to complete their lifecycle in this strain thus giving total number of
viruses developed.
Strain K have low number of plaques because in this strain only wild type T4viruses can grow
and complete their lifecycle..
Money laundering has become a mechanism for financing terrorist acti.pdf
Money laundering has become a mechanism for financing terrorist activities. Describe how and
why terrorist organizations use money laundering a tool for financing their activities. How can
investigators detect and investigate these schemes? What specific types of evidence will be
useful to investigate these crimes? Identify a real case of money laundering as an example in
your answer
Solution
Money laundering is process by which the criminals use the financial system to make illigetimate
money appear legitimate through a web of complex transactions.
Process of money laundering:
(i) Placement Stage : This is the initial stage in money laundering where in criminals move
physical cash in to the banking channel.
(ii) Layering stage : In this stage , the money deposited in the banks is routed through complex
financial transactions where the link to the origin of the funds is broken.
(iiI) Integration Stage : The illicit funds are now pushed in to the economy and financial system
by providing legitimate explanation for illegitimate funds.
Terrorist agencies use money laundering tools to finance their activities since in such a prcess it
is very difficult to establish the link to the illegally gotten money and trace it back to the crime.
Investigators can detect such schemes if they find any inconsistent business activites of
companies or individuals outside their routine activities. Such activities can include unusual high
cash transactions, dealing in multiple currencies, transactions which do not meet the business\'
core activities.
Some of the ways in which investigators can investigate the schemes are as below :
(i) The first step is to identify the business or individual profile of the criminal who has engaged
in such an activity.
(ii) If a business group or an organisation is involved then the next step is to identify the key
personnel who run the group since they will be directly involved in this.
(iii) The third step is identify the money flow patterns of the company and the location of the
bank accounts of the organisation.
(iv) Obtaining the financial records and the books of the company and corroborating the same
with externally obtained bank statements.
One of the world\'s most famous terrorist organisation Al Qaieda has been involved in multiple
terrorist crimes that has killed millions till date uses money laundering techniques to finance
their activities. The organisation had multiple financial interests through banks, holding
companies, foundations,properties and charities in Britain , France and many other European
countries. The organisation mainly took the help of BCCI in Britain in the 1980s before the bank
was closed down by Bank of England..

Independent auditors must provide dual opinions. What are these two opinions and what is the
difference in them?
Solution
Dual opinion is the opinion on the effectiveness and effective working of internal controls
adopted by the firm to avoid accounting manipulations . Firm adopt internal controls to present
financial statements at very best fair and transparent manner. So to avoid any deceit and
manipulation activities to hide any or miss any issue , internal controls are adopted . Auditors
also check the effectiveness of these controls and provide their opinion at the time of auditing the
financial statements.
Imperialism and Nationalism are often incongruous concepts that exis.pdf
Imperialism and Nationalism are often incongruous concepts that exist simultaneously in a given
context. During the period after WWI, nationalism was used to create new states in Europe and
the Middle East. Although these nations were recognized as independent, self-governing states,
they were either directly or indirectly connected to previously existing states. Discuss the ways
which Nationalism influenced the formation of new states. In your discussion, speak to the role
of imperialism to uphold, hinder or complicate the formation or survival of these states. Is it
possible to separate imperialistic goals from nation building? Support your argument with
evidence.
Solution
The First World War saw the colonial empires of France and Britain mobilised to aid European
and imperial war efforts. This mobilisation and the difficulties of demobilisation placed
considerable strain on imperial systems which were only partly addressed through post-war
reforms. The Great War also unleashed an unprecedented ideological challenge to colonial rule
embodied in the ideas of Woodrow Wilson which took form through the mandatory system.
Although there were some restrictions placed on the activities of the colonial powers, both
Britain and France maintained their imperial rule, often violently suppressing anti-colonial
nationalist challenges.
From a colonial perspective the First World War did not end cleanly. Major combat operations
on the Western Front may have ceased on 11 November 1918, but a raft of smaller conflicts,
some of which had emerged out of the upheavals of 1914-1918 and others which were only
tangentially related to the Great War, lingered on into the immediate post-war years. For
example, it was not until spring 1919 that, rather belatedly, German efforts launched at the start
of the war to stoke an Afghan challenge to the British Raj actually bore fruit. The Third Anglo-
Afghan War was more than just a continuation of the seemingly interminable struggle between
British imperial and Afghan forces along India’s north-western frontier. It was, in part, the
continuation of Germany’s Weltkrieg, an attempt to globalise the European struggle of 1914-
1918 in order to distract the Entente powers from the main theatre of operations.[1]
Unfortunately for Wilhelm II, German Emperor (1859-1941), the German army was defeated on
the Western Front before this globalisation of the war could achieve its aim of forcing the British
to choose between a European victory and their empire.
The Third Anglo-Afghan War was not an isolated event in the wake of the First World War.
Indeed, the decade following 1918 saw a major inter-state conflict being replaced by myriad
smaller ones, often within collapsing states and imperial polities. This was a point not lost on
contemporaries. In particular it was noted by, and arguably defined the thinking of, the arch-
pessimist of Britain’s post-war situation, General Sir Henry Wilson (1864-1922), the British
army’s Chief of the.

Explain why it can be problematic to base morality and ethics only o.pdf
Explain why it can be problematic to base morality and ethics only on religion.
Solution
The existence of ethics as a science, moral as a positive framework out of religion is as old as
civilization. Aristoteles and Platon stated that gods did not need of men, so religious moral is
unuseful. But, other authors as C.S. Lewis recognize that is possible moral behavior without be a
religious practice, however, the criterion of categorization between good or bad is not
sustainable, because it would be a preference choice, without transcendence.
Philosophers as Nietzsche, Kant or Holyoake agree about religion operates as an exogenous
imposition of behaviors, that they do not have any ethic value, because they are not self-
motivated, instead, non religious ethic is more valuable in this sense.
There is a general accepted principle about the religious freedom and the laicity of the State,
because religions has different emphasis and moral codes among the world, and the imposition
of demand ethical behaviors have been addressed to an specific religion is a violation of the
rights of the non followers of this faith.
However, society requires an objective system of convivence which respects everybody believes,
since there the need of a rational way of ranking moral decisions.
Other aspect is that it has been argued that many religious moral codes do not promote the self
superation, just they keep you saved of to be a criminal..

The Human Microbiome is defined a the collection of microbes- bacteria, viruses and single cell
eukaryotes that inhabits the human body. Microbes in adult human body are estimated to
outnumber human cells by a number of ten to one.

Consider an extension of the queue abstract data type, called a .pdf
Consider an extension of the queue abstract data type, called a minqueue, which supports
operations ENQUEUE, DEQUEUE, and FINDMIN. Assume that the elements to be stored are
integers (or any other totally ordered data type). FINDMIN simply returns the smallest element
in the minqueue, but does not remove it. Using a standard implementation of a queue, the
FINDMIN operation takes O(n) time in the worst case. However, consider a more clever data
structure for this abstract data type which works as follows: There are two regular queues used.
The first queue is called the ”real queue” and the second queue is called the ”helper queue”.
When the ENQUEUE(x) operation is performed, the element x is enqueued in the regular way on
the real queue. The element x is also enqueued at the end of the helper queue. However, if the
element y immediately ”in front” of x on the helper queue is larger than x, then y is removed
from the helper queue. This process of x annihilating the element immediately in front of it is
repeated until the element immediately in front of x is less than or equal to it or x is at the front
of the helper queue.
Describe how the DEQUEUE and FINDMIN operation are implemented in this data structure.
Give the worst case running time for each of ENQUEUE, DEQUEUE, and FINDMIN using this
data structure.
Give an argument using the potential method to show that any sequence of n ENQUEUE,

Case study on Queensland Health Payroll Debacle & Queensland Governm.pdf
Case study on Queensland Health Payroll Debacle & Queensland Government Bans IBM from
IT contracts.
Questions:
7. What could IBM have done to prevent the release of its defective payroll system?
Solution
The queensIsland had banned IBM for further contracts, following report about payroll system it
was blamed towards vendorers.
In 2010, government started introduction of IBM based Payroll system which makes million
bollers over budget and indulge payments to thousands of people.projects initiall expectations is
6.19 million dollars but current estimation cost about 1.2 billion dollars.
Early the qeens government has launced enquiry. the report that resluts out from enqury had
given in the week.the report gaves a critcal of all members including IBM.The problms which
makes project comes dowm, in major failure is by multiple peoape to loose up their
responsibility properly,” Richard who led enquery had said that..
then IBM is not allowed to any of the contracts with the state .which was said by Queeens
Government.
But IBM bought an application to claim up the damage, argue that in agrment signed in 2010 the
Government has waved its rights to sue.
This afternoon supreme court judge ruled IBM favour.it means that state government cannot go
for current damage
some defect are found in payroll system when it is launced in 2010 which produce a result that
many of the employees in the queen state had remaind withe unpaid and underpaid..

All businesses, small or large, depend on data centers. Answer the f.pdf
All businesses, small or large, depend on data centers. Answer the following questions related to
data centers:
Define data centers in terms of hardware, software, networks, and client-server
architecture/networks
What is the relationship between a business firm\'s MIS infrastructure and a business firm\'s data
center.
What are the implications of cloud computing for data centers?
How are SAAS, PAAS, and IAAS related to a firm\'s MIS infrastructure?
Solution
Data Centers : Its a place of hosting number of system and their related components.
Datacenters in terms of hardware, software, networks, client server architecture- could be
defined as physical components present collectively like caes, connectors, power supply units,
keyboard, mouse, audio speaker. Basically all the physical component that group up and come
up a large server to support applications running on it and handle the load.These server as the
clients to host the incoming and outgoing traffic to an application like consider a bank system
which has complete running website which constitue of the software part will be having
numerous amount of incoming request where simultaneously muliple user will be hitting the
system at once so the server(present in data center) should be able to handle so many request
which will require proper network system, CPUs etc to server it..

4. Records of the missions of Baja California in the form of baptism.pdf
4. Records of the missions of Baja California in the form of baptisms and burial records provide
an ideal opportunity to examine the consequences of what is known as the \"Colombian
Exchange,\" the movement of organisms large and small between the Old and New Worlds after
the appearance of Columbus in 1492. The data below are two time series of the numbers of
baptisms at two Central Baja missions, San Jose de Comondu and San Gertrudis. The data are for
the decade 1770 - 1779.
(a)
How would you generally describe the trend of baptisms for the two missions over this period?
Do the missions appear to show similar trends? Justify your response by appealing to the graph.
(b)
One of the influences of the meeting of the Old and New Worlds was the transmission of
diseases to the native populations, who had developed no natural immunity from European
diseases. If there were anecdotal evidence for an outbreak of disease during this time, which
mission and what year seems to be the most likely candidate? Again, justify your response by
appealing to the graph.

Anthophyta Which phyla have roots? Bryophyta Monilophyta Coniferophyta Anthophyta
Which phyla have stems? Bryophyta Monilophyta Coniferophyta Anthophyta Which phyla
have stomata and guard cells? Bryophyta Monilophyta Coniferophyta Anthophyta
Solution
Please find the answers below:
Part 32: Choice 4 (Anthophyta, or modern day plants or angiosperms are the most advanced
nature of plants which contain complex vascular tissues. They have separate conducting tissues
for water and food. Their sieve tubes contain companion cells and other accessory cells as well.)
Part 33: Choice 4 (As described above, anthophytes represent the modern day flowering plants or
angiosperms. They contain a true stem which gets lignified with time and becomes hard.
Although weak and tender stems are also visible and present in ferns and other lower plants, a
true hard lignified stem is found in conifers and angiosperms only)
Part 34: Choice 4 (The lower plants like bryophytes, pteridophytes etc do not contain true
vascular tissues. They are also devoid of any stomatal openings and guard cells. True stomata
and guard cells appeared in the flowering plants with diverse functions. Though some conifers
also contain stomata but generally, their stomatal openings are minimized to prevent evaporation
of water.).
Where do hydrogen bonds occur in the DNA structure and how does hydr.pdf
Where do hydrogen bonds occur in the DNA structure and how does hydrogen bonding
contribute to the secondary structure of DNA?
Solution
Ans). The two strands of DNA stay together by hydrogen bonds that is complementary
nucleotide base pairs. Two hydrogen bonds occur between the adenosine and the thymine base
pairs, and three hydrogen bonds occur between the cytosine and the guanine.
Secondary structure is the set of interactions between bases. In DNA the two strands of DNA are
held together by hydrogen bonds..
What is the concept of spoiled identity as it relates to disability.pdf
What is the concept of spoiled identity as it relates to disability?
Do you believe that some of all aspects of spoiled identify are inevitable?
Solution
While interacting with someone we tried to present ourselves to the other participants stigma is
an attribute that is discrediting do whatever we are trying to portray to others a particular identity
is set to be spoiled by having a stigma associated with it
Goffman points of that stigma will have great effect on the human beings. Anyone who is
disqualified from social acceptance is stigmatized. Stigma includez physical deformities
blemishes or tribal stigma like race and religion.
The stigmatized people are rejected and their face discrimination in the society. All these things
show the effect on self esteem academic achievement, performance et.
Stigmatization is a process in which the minorities are the inferior portions disqualified by the
powerful are superior people the stigmatized people become socially excluded based on their
characteristics that led to the stigma.
. Due to disabilities or external deformities like leprosy Muscular dystrophy cleft lip are
considered as what type of stigma gosselin emphasized how stigmatized people manage their
child identity before the normal people he also focused on stigma not as fixed or inherent
attribute of a person but described it as an experience.
In a research it was found that obese and overweight women feel uncomfortable and I\'m not
very social which makes other people which come into contact with them become an interesting
and it was found that the overweight women developed lower self esteem. Sometimes it is
inevitable but research is going on to rule out this..

What causes concrete to be hard (change from a fluid state into a ha.pdf
What causes concrete to be hard (change from a fluid state into a hardened state)?
Solution
Concrete is prepared by mixing cement, water, and aggregate together to make a workable paste.
It is molded or placed as desired, consolidated, and then left to harden. Concrete does not need to
dry out in order to harden as commonly thought.
The concrete (or specifically, the cement in it) needs moisture to hydrate and cure (harden).
When concrete dries, it actually stops getting stronger. Concrete with too little water may be dry
but is not fully reacted. The properties of such a concrete would be less than that of a wet
concrete. The reaction of water with the cement in concrete is extremely important to its
properties and reactions may continue for many years.
When water is added to cement, each of the compounds undergoes hydration and contributes to
the final concrete product. Only the calcium silicates contribute to strength. Tricalcium silicate is
responsible for most of the early strength (first 7 days). Dicalcium silicate, which reacts more
slowly, contributes only to the strength at later times..
What are parametric and nonparametric inferential testsName and d.pdf
What are parametric and nonparametric inferential tests?
Name and define the two types of chi-square tests.
Solution
There are two types of test data and consequently different types of analysis. Parametric data has
an underlying normal distribution which allows for more conclusions to be drawn as the shape
can be mathematically described. Anything else is non-parametric.
Parametric methods are those for which we know that the population is approximately normal, or
we can approximate using a normal distribution after we invoke the central limit theorem.
Non Parametric methods are statistical techniques for which we do not have to make any
assumption of normality for the population we are studying.
Chi-squared test of independence, Chi-squared Goodness of fit.
Two terrestrial ecosystems based on photosynthesis and and chemolith.pdf
Two terrestrial ecosystems based on photosynthesis and and chemolithosynthesis
(hydrothermal vents) trap their energy from specific energy sources. Tidal squeezing
has also been suggested. The type of energy sources define the character of the
ecosystems observed. What other energy source can you identify that might drive
other kinds of ecosystems elsewhere in the universe? Speculate on the type of
organisms that might evolve based on that energy source. What would be the
characteristics of the primary producers (the organisms that trap the energy)? How
can the energy be transferred to the rest of the food chain? What would a planet, where
such organisms evolved, be like?
DO NOT use energy sources listed above. Use an energy source that is plausible within
the laws of physics.
Just looking for a few main ideas that I can dive into to finish this promt..
Solution
i) Cosmic ray is other kind of energy source that might drive other kinds of ecosystems
elsewhere in the universe.
ii) The organism might evolve
iii) Characteristics of primary producer:
iv) The components present in the cosmic ray are absorbed by primary producer. Primary
consumer by eating the primary producer absorbed their organic substances and metabolizes
them. Secondary consumer behaves quite similarly eating the previous organism. In this way this
process goes on from one category organism to another. The transfer of energy through the food
chain determines some heat to be lost into the environment according to the thermodynamics
which indicates that secondary consumer will have less energy than primary consumer and
primary consumer have less energy than producer.
This transfer of energy from one trophic level to next is called efficiency of food chain.
v) In this scenario.

Operation Blue Star - Saka Neela Tara
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Explain why it can be problematic to base morality and ethics only o.pdf
Explain why it can be problematic to base morality and ethics only on religion.
Solution
The existence of ethics as a science, moral as a positive framework out of religion is as old as
civilization. Aristoteles and Platon stated that gods did not need of men, so religious moral is
unuseful. But, other authors as C.S. Lewis recognize that is possible moral behavior without be a
religious practice, however, the criterion of categorization between good or bad is not
sustainable, because it would be a preference choice, without transcendence.
Philosophers as Nietzsche, Kant or Holyoake agree about religion operates as an exogenous
imposition of behaviors, that they do not have any ethic value, because they are not self-
motivated, instead, non religious ethic is more valuable in this sense.
There is a general accepted principle about the religious freedom and the laicity of the State,
because religions has different emphasis and moral codes among the world, and the imposition
of demand ethical behaviors have been addressed to an specific religion is a violation of the
rights of the non followers of this faith.
However, society requires an objective system of convivence which respects everybody believes,
since there the need of a rational way of ranking moral decisions.
Other aspect is that it has been argued that many religious moral codes do not promote the self
superation, just they keep you saved of to be a criminal..

The Human Microbiome is defined a the collection of microbes- bacteria, viruses and single cell
eukaryotes that inhabits the human body. Microbes in adult human body are estimated to
outnumber human cells by a number of ten to one.
The Human Microbiome project is a United States National Institute of Health initiative with a

Consider an extension of the queue abstract data type, called a .pdf
Consider an extension of the queue abstract data type, called a minqueue, which supports
operations ENQUEUE, DEQUEUE, and FINDMIN. Assume that the elements to be stored are
integers (or any other totally ordered data type). FINDMIN simply returns the smallest element
in the minqueue, but does not remove it. Using a standard implementation of a queue, the
FINDMIN operation takes O(n) time in the worst case. However, consider a more clever data
structure for this abstract data type which works as follows: There are two regular queues used.
The first queue is called the ”real queue” and the second queue is called the ”helper queue”.
When the ENQUEUE(x) operation is performed, the element x is enqueued in the regular way on
the real queue. The element x is also enqueued at the end of the helper queue. However, if the
element y immediately ”in front” of x on the helper queue is larger than x, then y is removed
from the helper queue. This process of x annihilating the element immediately in front of it is
repeated until the element immediately in front of x is less than or equal to it or x is at the front
of the helper queue.
Describe how the DEQUEUE and FINDMIN operation are implemented in this data structure.
Give the worst case running time for each of ENQUEUE, DEQUEUE, and FINDMIN using this
data structure.
Give an argument using the potential method to show that any sequence of n ENQUEUE,
DEQUEUE, and FINDMIN operations requires only O(n) time. Or namely, the amortized
complexity of these operations is O(1).

the real queue. The element x is also enqueued at the end of the helper queue. However, if the
element y immediately ”in front” of x on the helper queue is larger than x, then y is removed
from the helper queue. This process of x annihilating the element immediately in front of it is
repeated until the element immediately in front of x is less than or equal to it or x is at the front
of the helper queue.
Describe how the DEQUEUE and FINDMIN operation are implemented in this data structure.
Give the worst case running time for each of ENQUEUE, DEQUEUE, and FINDMIN using this
data structure.
Give an argument using the potential method to show that any sequence of n ENQUEUE,
DEQUEUE, and FINDMIN operations requires only O(n) t.
Cordia Corporation is planning a 15 year project with an initial inv.pdf
Cordia Corporation is planning a 15 year project with an initial investment of $2,500,000.
The project will have $400,000 cash inflows per year in years 1-5 ;
$200,000 cash inflows in years 6-10, and
$40,000 cash inflows in years 11-15.
a) Determine this project\'s intemal rate of return.
b) If Cordia\'s opportunity cost of capital is 8%, should they accept or reject this project?
c) Explain your reason for your decision in part (b).
Solution
a) Computation of IRR:
IRR is an interest rate where the net present value of inflows are outflows equals zero.
With the help of trial and error method we can find the IRR:
First let us find from 5% rate and then we can increase or decrease as per the requirement (here,
our target is to get NPV= 0).

Case study on Queensland Health Payroll Debacle & Queensland Governm.pdf
Case study on Queensland Health Payroll Debacle & Queensland Government Bans IBM from
IT contracts.
Questions:
7. What could IBM have done to prevent the release of its defective payroll system?
Solution
The queensIsland had banned IBM for further contracts, following report about payroll system it
was blamed towards vendorers.
In 2010, government started introduction of IBM based Payroll system which makes million
bollers over budget and indulge payments to thousands of people.projects initiall expectations is
6.19 million dollars but current estimation cost about 1.2 billion dollars.
Early the qeens government has launced enquiry. the report that resluts out from enqury had
given in the week.the report gaves a critcal of all members including IBM.The problms which
makes project comes dowm, in major failure is by multiple peoape to loose up their
responsibility properly,” Richard who led enquery had said that..
then IBM is not allowed to any of the contracts with the state .which was said by Queeens
Government.
But IBM bought an application to claim up the damage, argue that in agrment signed in 2010 the
Government has waved its rights to sue.
This afternoon supreme court judge ruled IBM favour.it means that state government cannot go
for current damage
some defect are found in payroll system when it is launced in 2010 which produce a result that
many of the employees in the queen state had remaind withe unpaid and underpaid..

All businesses, small or large, depend on data centers. Answer the f.pdf
All businesses, small or large, depend on data centers. Answer the following questions related to
data centers:
Define data centers in terms of hardware, software, networks, and client-server
architecture/networks
What is the relationship between a business firm\'s MIS infrastructure and a business firm\'s data
center.
What are the implications of cloud computing for data centers?
How are SAAS, PAAS, and IAAS related to a firm\'s MIS infrastructure?
Solution
Data Centers : Its a place of hosting number of system and their related components.
Datacenters in terms of hardware, software, networks, client server architecture- could be
defined as physical components present collectively like caes, connectors, power supply units,
keyboard, mouse, audio speaker. Basically all the physical component that group up and come
up a large server to support applications running on it and handle the load.These server as the
clients to host the incoming and outgoing traffic to an application like consider a bank system
which has complete running website which constitue of the software part will be having
numerous amount of incoming request where simultaneously muliple user will be hitting the
system at once so the server(present in data center) should be able to handle so many request
which will require proper network system, CPUs etc to server it..

4. Records of the missions of Baja California in the form of baptism.pdf
4. Records of the missions of Baja California in the form of baptisms and burial records provide
an ideal opportunity to examine the consequences of what is known as the \"Colombian
Exchange,\" the movement of organisms large and small between the Old and New Worlds after
the appearance of Columbus in 1492. The data below are two time series of the numbers of
baptisms at two Central Baja missions, San Jose de Comondu and San Gertrudis. The data are for
the decade 1770 - 1779.
(a)
How would you generally describe the trend of baptisms for the two missions over this period?
Do the missions appear to show similar trends? Justify your response by appealing to the graph.
(b)
One of the influences of the meeting of the Old and New Worlds was the transmission of
diseases to the native populations, who had developed no natural immunity from European
diseases. If there were anecdotal evidence for an outbreak of disease during this time, which
mission and what year seems to be the most likely candidate? Again, justify your response by
appealing to the graph.

Anthophyta Which phyla have roots? Bryophyta Monilophyta Coniferophyta Anthophyta
Which phyla have stems? Bryophyta Monilophyta Coniferophyta Anthophyta Which phyla
have stomata and guard cells? Bryophyta Monilophyta Coniferophyta Anthophyta
Solution
Please find the answers below:
Part 32: Choice 4 (Anthophyta, or modern day plants or angiosperms are the most advanced
nature of plants which contain complex vascular tissues. They have separate conducting tissues
for water and food. Their sieve tubes contain companion cells and other accessory cells as well.)
Part 33: Choice 4 (As described above, anthophytes represent the modern day flowering plants or
angiosperms. They contain a true stem which gets lignified with time and becomes hard.
Although weak and tender stems are also visible and present in ferns and other lower plants, a
true hard lignified stem is found in conifers and angiosperms only)
Part 34: Choice 4 (The lower plants like bryophytes, pteridophytes etc do not contain true
vascular tissues. They are also devoid of any stomatal openings and guard cells. True stomata
and guard cells appeared in the flowering plants with diverse functions. Though some conifers
also contain stomata but generally, their stomatal openings are minimized to prevent evaporation
of water.).
Where do hydrogen bonds occur in the DNA structure and how does hydr.pdf
Where do hydrogen bonds occur in the DNA structure and how does hydrogen bonding
contribute to the secondary structure of DNA?
Solution
Ans). The two strands of DNA stay together by hydrogen bonds that is complementary
nucleotide base pairs. Two hydrogen bonds occur between the adenosine and the thymine base
pairs, and three hydrogen bonds occur between the cytosine and the guanine.
Secondary structure is the set of interactions between bases. In DNA the two strands of DNA are
held together by hydrogen bonds..
What is the concept of spoiled identity as it relates to disability.pdf
What is the concept of spoiled identity as it relates to disability?
Do you believe that some of all aspects of spoiled identify are inevitable?
Solution
While interacting with someone we tried to present ourselves to the other participants stigma is
an attribute that is discrediting do whatever we are trying to portray to others a particular identity
is set to be spoiled by having a stigma associated with it
Goffman points of that stigma will have great effect on the human beings. Anyone who is
disqualified from social acceptance is stigmatized. Stigma includez physical deformities
blemishes or tribal stigma like race and religion.
The stigmatized people are rejected and their face discrimination in the society. All these things
show the effect on self esteem academic achievement, performance et.
Stigmatization is a process in which the minorities are the inferior portions disqualified by the
powerful are superior people the stigmatized people become socially excluded based on their
characteristics that led to the stigma.
. Due to disabilities or external deformities like leprosy Muscular dystrophy cleft lip are
considered as what type of stigma gosselin emphasized how stigmatized people manage their
child identity before the normal people he also focused on stigma not as fixed or inherent
attribute of a person but described it as an experience.
In a research it was found that obese and overweight women feel uncomfortable and I\'m not
very social which makes other people which come into contact with them become an interesting
and it was found that the overweight women developed lower self esteem. Sometimes it is
inevitable but research is going on to rule out this..

What causes concrete to be hard (change from a fluid state into a ha.pdf
What causes concrete to be hard (change from a fluid state into a hardened state)?
Solution
Concrete is prepared by mixing cement, water, and aggregate together to make a workable paste.
It is molded or placed as desired, consolidated, and then left to harden. Concrete does not need to
dry out in order to harden as commonly thought.
The concrete (or specifically, the cement in it) needs moisture to hydrate and cure (harden).
When concrete dries, it actually stops getting stronger. Concrete with too little water may be dry
but is not fully reacted. The properties of such a concrete would be less than that of a wet
concrete. The reaction of water with the cement in concrete is extremely important to its
properties and reactions may continue for many years.
When water is added to cement, each of the compounds undergoes hydration and contributes to
the final concrete product. Only the calcium silicates contribute to strength. Tricalcium silicate is
responsible for most of the early strength (first 7 days). Dicalcium silicate, which reacts more
slowly, contributes only to the strength at later times..
What are parametric and nonparametric inferential testsName and d.pdf
What are parametric and nonparametric inferential tests?
Name and define the two types of chi-square tests.
Solution
There are two types of test data and consequently different types of analysis. Parametric data has
an underlying normal distribution which allows for more conclusions to be drawn as the shape
can be mathematically described. Anything else is non-parametric.
Parametric methods are those for which we know that the population is approximately normal, or
we can approximate using a normal distribution after we invoke the central limit theorem.
Non Parametric methods are statistical techniques for which we do not have to make any
assumption of normality for the population we are studying.
Chi-squared test of independence, Chi-squared Goodness of fit.
Two terrestrial ecosystems based on photosynthesis and and chemolith.pdf
Two terrestrial ecosystems based on photosynthesis and and chemolithosynthesis
(hydrothermal vents) trap their energy from specific energy sources. Tidal squeezing
has also been suggested. The type of energy sources define the character of the
ecosystems observed. What other energy source can you identify that might drive
other kinds of ecosystems elsewhere in the universe? Speculate on the type of
organisms that might evolve based on that energy source. What would be the
characteristics of the primary producers (the organisms that trap the energy)? How
can the energy be transferred to the rest of the food chain? What would a planet, where
such organisms evolved, be like?
DO NOT use energy sources listed above. Use an energy source that is plausible within
the laws of physics.
Just looking for a few main ideas that I can dive into to finish this promt..
Solution
i) Cosmic ray is other kind of energy source that might drive other kinds of ecosystems
elsewhere in the universe.
ii) The organism might evolve
iii) Characteristics of primary producer:
iv) The components present in the cosmic ray are absorbed by primary producer. Primary
consumer by eating the primary producer absorbed their organic substances and metabolizes
them. Secondary consumer behaves quite similarly eating the previous organism. In this way this
process goes on from one category organism to another. The transfer of energy through the food
chain determines some heat to be lost into the environment according to the thermodynamics
which indicates that secondary consumer will have less energy than primary consumer and
primary consumer have less energy than producer.
This transfer of energy from one trophic level to next is called efficiency of food chain.
v) In this scenario.

Operation Blue Star - Saka Neela Tara
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdf
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.
2024.06.01 Introducing a competency framework for languag learning materials ...
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Describe what is happening in Italy (or you may substitute Argentina.pdf
- 1. Describe what is happening in Italy (or you may substitute Argentina or Iran) and how that might impact things like exchange rates, inflation and/or interest rates. Solution Let we take example of Iran, As we all know that USA has put a number of sanctions on Iran due to which trade with Iran is difficult, Country like India which Import a major portion of its crue oil import from Iran, now after these sanctions, India could not buy crude oil from Iran and this will also happen with other countries too. So this types of sanctions will force Countries like India to look for another partner for Oil import and this will have impact on its currency exchange rates as other oil exporting countries may demand different price for the crude oil. on other hand after so many sanctions Supply of curde oil will increase and prices may also increases which will result in more pressure on countries and this will have impact on exchange rate and when prices of crude oil will increase it will impact economy and inflation will also increase and general price level will also increase.
