Executive Summary i. Provide a succinct overview of your strategic plan on coca cola.
Solution
Coca Cola is a global beverage brand based at USA. It has a strong positioning in soft drink and
non -alcoholic beverages. Due to global shift in the mindset of consumers, it should restructure
its strategic plan to take leadership position in soft drink as well as Fast moving consumer goods
(FMCG) products across the global market. It should revise its strategic intent by moulding its
mission as to produce more hygienic and less soda as ingradinets products in soft drink.
Globally, consumers are health conscious so they are not showing interest in more soda based
drink. So, Coca Cola will plan its product designing strategies to attract more no. of customers as
well as getting a sophisticated share in the carbonated soft drink. Even, it is utilizing its brand
value in making its current business plans, policies, procedures etc. more focused towards the
sustainable development. In this, only those process or products are utilized which refine the
excessively use of water, plants etc. as an inputs its manufacturing for global supplies..

Essay questionPorter Combining business strategy What is itmeani.pdf
Essay question:
Porter Combining business strategy: What is itmeaning? - What is the idea? - Why is it
important?
Solution
Strategy According to Michael Porter
In a 1996 Harvard Business Review article [5] and in an earlier book [6], Porter argues that
competitive strategy is \"about being different.\" He adds, \"It means deliberately choosing a
different set of activities to deliver a unique mix of value.\" In short, Porter argues that strategy is
about competitive position, about differentiating yourself in the eyes of the customer, about
adding value through a mix of activities different from those used by competitors. In his earlier
book, Porter defines competitive strategy as \"a combination of the ends (goals) for which the
firm is striving and the means (policies) by which it is seeking to get there.\" Thus, Porter seems
to embrace strategy as both plan and position. (It should be noted that Porter writes about
competitive strategy, not about strategy in general.)
COMBINATION STRATEGIES
Can forms of competitive advantage be combined? Porter asserts that a successful strategy
requires a firm to aggressively stake out a market position, and that different strategies involve
distinctly different approaches to competing and operating the business. An organization
pursuing a differentiation strategy seeks competitive advantage by offering products or services
that are unique from those offered by rivals, either through design, brand image, technology,
features, or customer service. Alternatively, an organization pursuing a cost leadership strategy
attempts to gain competitive advantage based on being the overall low-cost provider of a product
or service. To be \"all things to all people\" can mean becoming \"stuck in the middle\" with no
distinct competitive advantage. The difference between being \"stuck in the middle\" and
successfully pursuing combination strategies merits discussion. Although Porter describes the
dangers of not being successful in either cost control or differentiation, some firms have been
able to succeed using combination strategies.
Research suggests that, in some cases, it is possible to be a cost leader while maintaining a
differentiated product. Southwest Airlines has combined cost cutting measures with
differentiation. The company has been able to reduce costs by not assigning seating and by
eliminating meals on its planes. It has then been able to promote in its advertising that one does
not get tasteless airline food on its flights. Its fares have been low enough to attract a significant
number of passengers, allowing the airline to succeed.
Another firm that has pursued an effective combination strategy is Nike. When customer
preferences moved to wide-legged jeans and cargo pants, Nike\'s market share slipped.
Competitors such as Adidas offered less expensive shoes and undercut Nike\'s price. Nike\'s
stock price dropped in 1998 to half its 1997 high. However, Nike reported a 70 percent increase
in earnings for.
During oogenesis, will the genotypes of the first and second polar b.pdf
During oogenesis, will the genotypes of the first and second polar bodies be identical? Explain.
Solution
No. The oocyte development occurs through meiosis, which divides the chromosomes. Crossing
over of homologus chromosomes also takes place which adds differences in the daughter cells
produced. Moreover, the first and secondary polar bodies are produced in different phases of
meiosis. As they divide before the mitotic phase of meiosis, the two polar bodies cannot br
identical..

Determine whether each series is convergent or divergent.
4)Determine whether the series converges or diverges.
5)Determine whether the sequence converges or diverges.
Solution
a)
Looking at the right-hand side of the Riemann zeta-function, we recognizeit to be a p-series with
p = x. We know that p-series only converge when p > 1and that they diverge whenever p <= 1,
so the domain of the Riemann zeta-function is
(1,)={x:x>1}.

Describe the primary differences between WEP, WPA, and WPA2 protocol.pdf
Describe the primary differences between WEP, WPA, and WPA2 protocols. b. Describe how
algorithms enhance the security of the above protocols.
Solution
differences between WEP, WPA, and WPA2 protocols:
Wired Equivalent Privacy (WEP)
Wired Equivalent Privacy (WEP) is the most widely used Wi-Fi security algorithm in the world.
This is a function of age, backwards compatibility, and the fact that it appears first in the
encryption type selection menus in many router control panels.
WEP was ratified as a Wi-Fi security standard in September of 1999. The first versions of WEP
weren’t particularly strong, even for the time they were released, because U.S. restrictions on the
export of various cryptographic technology led to manufacturers restricting their devices to only
64-bit encryption. When the restrictions were lifted, it was increased to 128-bit. Despite the
introduction of 256-bit WEP encryption, 128-bit remains one of the most common
implementations.
Despite revisions to the algorithm and an increased key size, over time numerous security flaws
were discovered in the WEP standard and, as computing power increased, it became easier and
easier to exploit them. As early as 2001 proof-of-concept exploits were floating around and by
2005 the FBI gave a public demonstration (in an effort to increase awareness of WEP’s
weaknesses) where they cracked WEP passwords in minutes using freely available software.
Despite various improvements, work-arounds, and other attempts to shore up the WEP system, it
remains highly vulnerable and systems that rely on WEP should be upgraded or, if security
upgrades are not an option, replaced. The Wi-Fi Alliance officially retired WEP in 2004.
Wi-Fi Protected Access (WPA)
Wi-Fi Protected Access was the Wi-Fi Alliance’s direct response and replacement to the
increasingly apparent vulnerabilities of the WEP standard. It was formally adopted in 2003, a
year before WEP was officially retired. The most common WPA configuration is WPA-PSK
(Pre-Shared Key). The keys used by WPA are 256-bit, a significant increase over the 64-bit and
128-bit keys used in the WEP system.
Some of the significant changes implemented with WPA included message integrity checks (to
determine if an attacker had captured or altered packets passed between the access point and
client) and the Temporal Key Integrity Protocol (TKIP). TKIP employs a per-packet key system
that was radically more secure than fixed key used in the WEP system. TKIP was later
superseded by Advanced Encryption Standard (AES).
Despite what a significant improvement WPA was over WEP, the ghost of WEP haunted WPA.
TKIP, a core component of WPA, was designed to be easily rolled out via firmware upgrades
onto existing WEP-enabled devices. As such it had to recycle certain elements used in the WEP
system which, ultimately, were also exploited.
WPA, like its predecessor WEP, has been shown via both proof-of-concept and applied public
demonstrations to be vulnerable to intrusion. Inte.

Why would you pin a file to a taskbar button\'s jump List? You can use a feature called ___ to
list the thumbnails of open windows as you snap a window into place. How can you quickly
minimize all open windows on the desktop? Explain how to create a virtual desktop. Name two
ways you can change the appearance of a tile on the Start menu. What can you do with the
Reader app? Explain how to personalize the user icon on the Start menu.
Solution
1. How do you change the position of taskbar buttons?
Simply right click on the taskbar button, and drag it to the desired location, and leave it.
2. Why would you pin a file to a taskbar buttons Jump List?
Usually, the file which needs a frequent access, something like Windows Explorer, and if you
are
an accountant something like MS-Word, for a photographer something like PhotoShop, these
files
will be accessed almost regularly multiple times a day. So, to make such kind of files handy,
we could pin those files to the taskbar, so that they can be opened with just a click away.
3. You can use a feature called __Aero__ to list the thumbnails of open windows as you snap a
window into place.
Aero is the one which features Snap(to resize open windows), Peek(view open windows), Shake
(close all windows except the selected one) etc.
4. How can you quickly minimize all open windows on the desktop?
Just click on the right corner of the taskbar, which shows a label Show Desktop when your
mouse hovers there.
5. Explain how to create a virtual desktop?
The steps required to create a virtual desktop include:
-> Open a Task View pane which is available on the taskbar, or by pressing WindowKey + Tab
-> In the Task View pane, click New desktop which creates another virtual desktop..

What was the causes of the Vietnam war What was the causes of .pdf
What was the causes of the Vietnam war?
What was the causes of the Vietnam war?
Solution
The causes of the Vietnam War were derived from the symptoms, components and consequences
of the Cold War. The causes of the Vietnam War revolve around the simple belief held by
America that communism was threatening to expand all over south-east Asia
The US entered the conflict in South Vietnam based on the much maligned \"Domino Theory\"
concept. From the perspective of the Nation\'s leader, this was a very real threat both in terms of
nation\'s falling one by one to communism and with regards to the resultant impacts.
The most significant driver for US involvement in South Vietnam was the Korean War. It
established the notion of a \"civil war\" in which the northern communists were extensively
supported by outside forces and that a conventional invasion was the greatest threat.
On June 25, 1950, North Korea invaded South Korea. The US and its allies spent three years
fighting a very brutal war against the North Koreans, the Chinese and the Soviets. Eventually, it
ended in a stalemate. By definition, on June 25, 1950, this was a civil war.However, by the time
the US entered the Vietnam conflict, there was ample near term historical precedence for the
spread of communism.
In 1954, Vietnamese communist forces defeat the French which leads to the 1954 Geneva
convention in which the region was divided into North and South Vietnam, Laos, and Cambodia.
In 1959, the government of Laos collapses and the Pathet Lao (communist forces backed by the
North Vietnamese) begin to fight for control of the country. A civil war backed by external
communist forces.
It was evident to the US and its allies that communism was spreading throughout the region.
Each state which fell served as a launch point for communist operations in nearby countries
(China into Korea and Vietnam, China and North Vietnam into Laos and Cambodia). Therefore
to prevent further spread to allies to include Thailand and Japan among others, communism had
to be contained.
Based on the results of communist rule in the countries that fell, it seems the concerns were
genuine. South Vietnam asked for help from its SEATO allies and the US responded as it should
under treaty obligation.
The argument that this was civil war substantially underplays the assistance the North
Vietnamese received from the Chinese and Soviets. It was as much a civil war as the Korean
War was.
Some 1.5 million Chinese were executed during the land reforms and counter-revolutionary
executions following the Chinese victory in 1948. In the early 1960s, following the Great Leap
Forward, approximately 2.5 million people were executed, Up to 1 million people were executed
or died in concentration camps in North Korea by the start of the US involvement in Vietnam.
Between 1953 and 1956, the Land reform in North Vietnam carried out by the Communists
resulted in the deaths, by various estimates, of almost 200,ooo landowners via public kanga.

This is for an homework assignment using Java code. Here is the home.pdf
This is for an homework assignment using Java code. Here is the homework:
Objective:
Write a game where you are an X trying to get an ice cream cone in a mine field
Before the game starts, a field of mines are created.
The board has to be first initialized
There mines occupy a tenth of the board (IE (BoardSize x BoardSize)/10 = the number of mines)
The mines are randomly placed on the board. If a space which is already occupied (either by the
player, the ice cream cone, or another mine) is selected then another space must be selected until
an empty space is found.
The player is placed at 0,0
The ice cream cone is placed at a random location on the board
At each turn, the player chooses to move in the X or Y direction by entering either -1, 0, or 1,
where
-1 is going one space in the negative direction
1 is going one space in the positive direction (remember positive for Y is down)
0 is staying still
9 quits the game
Anything other than these values should prompt the player that they have inputted an invalid
value and then not move in that direction (IE 0).
Before each turn the board is displayed indicating where the player (X) and the goal (^) are
located. Unoccupied spaces and mines are denoted by and underscore (_). Remember mines need
to be hidden so they are also underscores (_). The board is maximum 10 spaces long and wide.
Once the player reaches the ice cream cone the player wins
If the player lands on a space with a mine they are killed and the game is over
After the game is over, the player should be prompted whether or not they want to play again.
Example Dialog:

Would you like to play again?
This is the code I have so far. And it works fine. But when you land on a bomb or the ice cream
and it ask you to play again, if you say yes then it doesn\'t reset the game board. Instead it just
continues from where the \"X\" last was on the board. How can I reset the board at the end if the
user wants to play again?

ObjectiveCreate a graphical game of minesweeper IN JAVA. The boar.pdf
Objective:
Create a graphical game of minesweeper IN JAVA. The board should consist of 10x10 buttons.
Of the 100 spaces there should be at least 20 randomly placed mines. If the button is clicked and
it is not a mine then it clears itself. If a space has been cleared then it should indicate how many
of its eight neighbors are mines. If a space is clicked and it is a mine then the game is over and
the player is asked if they want to play again. Finally, if all the non-mine spaces have been
clicked then the player is prompted that they won.
Solution

Locate an article where the technique of Polymerase chain reaction (PCR) is used.Describe the
technique briefly based on your study material, and explain how this technique provided the
authors with the key information for their results and conclusions.
Solution
This article fairly explain the PCR technique.
\"Activation of Wnt/beta-catenin/Tcf signaling pathway in human astrocytomas\"
In this article Semi -Quantitative PCR technique is used for the analysis of mRNA levels of -
Catenin/Tcf Signaling components.
Initially total RNA isolated from Freezed brain Astrocyte tissue. From thios RNA, cDNA
synthecized using Takara cDNA reverse transcriptase kit. Then the produced cDNA is amplified
with different primers of the -Catenin/Tcf Signaling components that include Dvl-1, Dvl-2, Dvl-
3, beta-catenin, c-myc and cyclin D1.
The mRNA levels were positively correlated with the histological malignancy. Our studies tend
to suggest that Wnt/beta-catenin/Tcf signaling pathway is implicated in malignancy of
astrocytomas.
It is said that the CEO and other corporate leaders are keepers of t.pdf
It is said that the CEO and other corporate leaders are keepers of the organization\'s memory.
Please discuss this.
Solution
Organizational memory comprises of largely undocumented experience, insights, knowledge,
and skills acquired over the years, passed on to the newcomers through personal contacts,
meetings, training courses, and mentor-protégé relationships. A lot happens within the
organization which is not documented but is discussed over meetings, experiences and learnings
passed over to successors. Some of that knowledge is explicit knowledge that core members can
access easily, and are not easily documented. These are generally oral communications and is
shared or observed in presence of senior business leaders including CEOs. When those learnings
cease to provide any value proposition to the organization, “unlearning” has to occur, so that new
learnings are inculcated and new milestones are pursued in order to sustain the business..
Arrange these compounds in order of increasing boiling point. I. buta.pdf
Arrange these compounds in order of increasing boiling point. I. butanal II. diethyl ether III. 2-
butanol 0 Type here to search
Solution
Answer is option 2) II < I < III.
Reason: butanol will have higher boiling point due to hydrogen bonding, next highest is butanal
since it is a highly polar compound when compare to diethyl ether.diethyl ether is least polar and
lesser boiling point..

Solution
As per Thomas L.Friedman
Now the real IT revolution is about to begin as all the complementarities between these tools
start to really work together to level the playing field. One of those who pulled back the curtain
and called this moment by its real name was HP’s Carly Fiorina, who in 2004 began to declare in
her public speeches that the dot-com boom and bust were just “the end of the beginning.” The
last 25 years in technology, said Fiorina, have been just “the warm-up act”. Now we are going

In a liquid-liquid extraction, the first liquid added was 30mL of 0..pdf
In a liquid-liquid extraction, the first liquid added was 30mL of 0.20M NaOH with
Thymolphalein Indicator (blue color). Then, 30mL of 0.25M of Cinnamic Acid in Ethyl Acetate
was added. These two immicicble liquids formed two layers when added together.
Describe why the aqueous layer turns colorless during the extraction process. Be specific in your
explanation.
Solution
Since the transition range of thymolphthalein indicator is around 9.3 to 10.5, below this it is
colorless. Here the ethyl acetate does not deprotonate completely as all the NaOH is exhasusted
to deprotonate the .20 M of acid. Remaining .05 M of acid could not be neutralize and thus
contributing in lowering the pH. Hence, the pH is below 9.3 and indicator turns colorless
indicating more concentration of acid than base..
How is the resistance of a solution is a function of the nature of t.pdf
How is the resistance of a solution is a function of the nature of the substance dissolved in it.
What is conductivity and how is it related to resistance. What is specific conductivity? Please
explain.
Solution
Consider a polar solvent water where the ionic substances or electrolytes get split up into ions
and dissolve in water but the non polar substances do not dissolve in water. Therefore resistance
of a solution depends upon nature of substance dissolved. Conductivity is a degree to which a
specific material gets to conduct electricity. Conductivity is the inverse of resistivity. Specific
conductivity is the measure of ability to which a substance cab conduct electricity on the whole..

Describe the primary differences between WEP, WPA, and WPA2 protocol.pdf
Describe the primary differences between WEP, WPA, and WPA2 protocols. b. Describe how
algorithms enhance the security of the above protocols.
Solution
differences between WEP, WPA, and WPA2 protocols:
Wired Equivalent Privacy (WEP)
Wired Equivalent Privacy (WEP) is the most widely used Wi-Fi security algorithm in the world.
This is a function of age, backwards compatibility, and the fact that it appears first in the
encryption type selection menus in many router control panels.
WEP was ratified as a Wi-Fi security standard in September of 1999. The first versions of WEP
weren’t particularly strong, even for the time they were released, because U.S. restrictions on the
export of various cryptographic technology led to manufacturers restricting their devices to only
64-bit encryption. When the restrictions were lifted, it was increased to 128-bit. Despite the
introduction of 256-bit WEP encryption, 128-bit remains one of the most common
implementations.
Despite revisions to the algorithm and an increased key size, over time numerous security flaws
were discovered in the WEP standard and, as computing power increased, it became easier and
easier to exploit them. As early as 2001 proof-of-concept exploits were floating around and by
2005 the FBI gave a public demonstration (in an effort to increase awareness of WEP’s
weaknesses) where they cracked WEP passwords in minutes using freely available software.
Despite various improvements, work-arounds, and other attempts to shore up the WEP system, it
remains highly vulnerable and systems that rely on WEP should be upgraded or, if security
upgrades are not an option, replaced. The Wi-Fi Alliance officially retired WEP in 2004.
Wi-Fi Protected Access (WPA)
Wi-Fi Protected Access was the Wi-Fi Alliance’s direct response and replacement to the
increasingly apparent vulnerabilities of the WEP standard. It was formally adopted in 2003, a
year before WEP was officially retired. The most common WPA configuration is WPA-PSK
(Pre-Shared Key). The keys used by WPA are 256-bit, a significant increase over the 64-bit and
128-bit keys used in the WEP system.
Some of the significant changes implemented with WPA included message integrity checks (to
determine if an attacker had captured or altered packets passed between the access point and
client) and the Temporal Key Integrity Protocol (TKIP). TKIP employs a per-packet key system
that was radically more secure than fixed key used in the WEP system. TKIP was later
superseded by Advanced Encryption Standard (AES).
Despite what a significant improvement WPA was over WEP, the ghost of WEP haunted WPA.
TKIP, a core component of WPA, was designed to be easily rolled out via firmware upgrades
onto existing WEP-enabled devices. As such it had to recycle certain elements used in the WEP
system which, ultimately, were also exploited.
WPA, like its predecessor WEP, has been shown via both proof-of-concept and applied public
demonstrations to be vulnerable to intrusion. Inte.

Why would you pin a file to a taskbar button\'s jump List? You can use a feature called ___ to
list the thumbnails of open windows as you snap a window into place. How can you quickly
minimize all open windows on the desktop? Explain how to create a virtual desktop. Name two
ways you can change the appearance of a tile on the Start menu. What can you do with the
Reader app? Explain how to personalize the user icon on the Start menu.
Solution
1. How do you change the position of taskbar buttons?
Simply right click on the taskbar button, and drag it to the desired location, and leave it.
2. Why would you pin a file to a taskbar buttons Jump List?
Usually, the file which needs a frequent access, something like Windows Explorer, and if you
are
an accountant something like MS-Word, for a photographer something like PhotoShop, these
files
will be accessed almost regularly multiple times a day. So, to make such kind of files handy,
we could pin those files to the taskbar, so that they can be opened with just a click away.
3. You can use a feature called __Aero__ to list the thumbnails of open windows as you snap a
window into place.
Aero is the one which features Snap(to resize open windows), Peek(view open windows), Shake
(close all windows except the selected one) etc.
4. How can you quickly minimize all open windows on the desktop?
Just click on the right corner of the taskbar, which shows a label Show Desktop when your
mouse hovers there.
5. Explain how to create a virtual desktop?
The steps required to create a virtual desktop include:
-> Open a Task View pane which is available on the taskbar, or by pressing WindowKey + Tab
-> In the Task View pane, click New desktop which creates another virtual desktop..

What was the causes of the Vietnam war What was the causes of .pdf
What was the causes of the Vietnam war?
What was the causes of the Vietnam war?
Solution
The causes of the Vietnam War were derived from the symptoms, components and consequences
of the Cold War. The causes of the Vietnam War revolve around the simple belief held by
America that communism was threatening to expand all over south-east Asia
The US entered the conflict in South Vietnam based on the much maligned \"Domino Theory\"
concept. From the perspective of the Nation\'s leader, this was a very real threat both in terms of
nation\'s falling one by one to communism and with regards to the resultant impacts.
The most significant driver for US involvement in South Vietnam was the Korean War. It
established the notion of a \"civil war\" in which the northern communists were extensively
supported by outside forces and that a conventional invasion was the greatest threat.
On June 25, 1950, North Korea invaded South Korea. The US and its allies spent three years
fighting a very brutal war against the North Koreans, the Chinese and the Soviets. Eventually, it
ended in a stalemate. By definition, on June 25, 1950, this was a civil war.However, by the time
the US entered the Vietnam conflict, there was ample near term historical precedence for the
spread of communism.
In 1954, Vietnamese communist forces defeat the French which leads to the 1954 Geneva
convention in which the region was divided into North and South Vietnam, Laos, and Cambodia.
In 1959, the government of Laos collapses and the Pathet Lao (communist forces backed by the
North Vietnamese) begin to fight for control of the country. A civil war backed by external
communist forces.
It was evident to the US and its allies that communism was spreading throughout the region.
Each state which fell served as a launch point for communist operations in nearby countries
(China into Korea and Vietnam, China and North Vietnam into Laos and Cambodia). Therefore
to prevent further spread to allies to include Thailand and Japan among others, communism had
to be contained.
Based on the results of communist rule in the countries that fell, it seems the concerns were
genuine. South Vietnam asked for help from its SEATO allies and the US responded as it should
under treaty obligation.
The argument that this was civil war substantially underplays the assistance the North
Vietnamese received from the Chinese and Soviets. It was as much a civil war as the Korean
War was.
Some 1.5 million Chinese were executed during the land reforms and counter-revolutionary
executions following the Chinese victory in 1948. In the early 1960s, following the Great Leap
Forward, approximately 2.5 million people were executed, Up to 1 million people were executed
or died in concentration camps in North Korea by the start of the US involvement in Vietnam.
Between 1953 and 1956, the Land reform in North Vietnam carried out by the Communists
resulted in the deaths, by various estimates, of almost 200,ooo landowners via public kanga.

This is for an homework assignment using Java code. Here is the homework:
Objective:
Write a game where you are an X trying to get an ice cream cone in a mine field
Before the game starts, a field of mines are created.
The board has to be first initialized
There mines occupy a tenth of the board (IE (BoardSize x BoardSize)/10 = the number of mines)
The mines are randomly placed on the board. If a space which is already occupied (either by the
player, the ice cream cone, or another mine) is selected then another space must be selected until
an empty space is found.
The player is placed at 0,0
The ice cream cone is placed at a random location on the board
At each turn, the player chooses to move in the X or Y direction by entering either -1, 0, or 1,
where
-1 is going one space in the negative direction
1 is going one space in the positive direction (remember positive for Y is down)
0 is staying still
9 quits the game
Anything other than these values should prompt the player that they have inputted an invalid
value and then not move in that direction (IE 0).
Before each turn the board is displayed indicating where the player (X) and the goal (^) are
located. Unoccupied spaces and mines are denoted by and underscore (_). Remember mines need
to be hidden so they are also underscores (_). The board is maximum 10 spaces long and wide.
Once the player reaches the ice cream cone the player wins
If the player lands on a space with a mine they are killed and the game is over
After the game is over, the player should be prompted whether or not they want to play again.
Example Dialog:

Would you like to play again?
This is the code I have so far. And it works fine. But when you land on a bomb or the ice cream
and it ask you to play again, if you say yes then it doesn\'t reset the game board. Instead it just
continues from where the \"X\" last was on the board. How can I reset the board at the end if the
user wants to play again?

ObjectiveCreate a graphical game of minesweeper IN JAVA. The boar.pdf
Objective:
Create a graphical game of minesweeper IN JAVA. The board should consist of 10x10 buttons.
Of the 100 spaces there should be at least 20 randomly placed mines. If the button is clicked and
it is not a mine then it clears itself. If a space has been cleared then it should indicate how many
of its eight neighbors are mines. If a space is clicked and it is a mine then the game is over and
the player is asked if they want to play again. Finally, if all the non-mine spaces have been
clicked then the player is prompted that they won.
Solution
2 files need to be made.

Locate an article where the technique of Polymerase chain reaction (.pdf
Locate an article where the technique of Polymerase chain reaction (PCR) is used.Describe the
technique briefly based on your study material, and explain how this technique provided the
authors with the key information for their results and conclusions.
Solution
This article fairly explain the PCR technique.
\"Activation of Wnt/beta-catenin/Tcf signaling pathway in human astrocytomas\"
In this article Semi -Quantitative PCR technique is used for the analysis of mRNA levels of -
Catenin/Tcf Signaling components.
Initially total RNA isolated from Freezed brain Astrocyte tissue. From thios RNA, cDNA
synthecized using Takara cDNA reverse transcriptase kit. Then the produced cDNA is amplified
with different primers of the -Catenin/Tcf Signaling components that include Dvl-1, Dvl-2, Dvl-
3, beta-catenin, c-myc and cyclin D1.
The mRNA levels were positively correlated with the histological malignancy. Our studies tend
to suggest that Wnt/beta-catenin/Tcf signaling pathway is implicated in malignancy of
astrocytomas.
It is said that the CEO and other corporate leaders are keepers of t.pdf
It is said that the CEO and other corporate leaders are keepers of the organization\'s memory.
Please discuss this.
Solution
Organizational memory comprises of largely undocumented experience, insights, knowledge,
and skills acquired over the years, passed on to the newcomers through personal contacts,
meetings, training courses, and mentor-protégé relationships. A lot happens within the
organization which is not documented but is discussed over meetings, experiences and learnings
passed over to successors. Some of that knowledge is explicit knowledge that core members can
access easily, and are not easily documented. These are generally oral communications and is
shared or observed in presence of senior business leaders including CEOs. When those learnings
cease to provide any value proposition to the organization, “unlearning” has to occur, so that new
learnings are inculcated and new milestones are pursued in order to sustain the business..
Arrange these compounds in order of increasing boiling point. I. buta.pdf
Arrange these compounds in order of increasing boiling point. I. butanal II. diethyl ether III. 2-
butanol 0 Type here to search
Solution
Answer is option 2) II < I < III.
Reason: butanol will have higher boiling point due to hydrogen bonding, next highest is butanal
since it is a highly polar compound when compare to diethyl ether.diethyl ether is least polar and
lesser boiling point..

As per Thomas L.Friedman
Now the real IT revolution is about to begin as all the complementarities between these tools
start to really work together to level the playing field. One of those who pulled back the curtain
and called this moment by its real name was HP’s Carly Fiorina, who in 2004 began to declare in
her public speeches that the dot-com boom and bust were just “the end of the beginning.” The
last 25 years in technology, said Fiorina, have been just “the warm-up act”. Now we are going

In a liquid-liquid extraction, the first liquid added was 30mL of 0..pdf
In a liquid-liquid extraction, the first liquid added was 30mL of 0.20M NaOH with
Thymolphalein Indicator (blue color). Then, 30mL of 0.25M of Cinnamic Acid in Ethyl Acetate
was added. These two immicicble liquids formed two layers when added together.
Describe why the aqueous layer turns colorless during the extraction process. Be specific in your
explanation.
Solution
Since the transition range of thymolphthalein indicator is around 9.3 to 10.5, below this it is
colorless. Here the ethyl acetate does not deprotonate completely as all the NaOH is exhasusted
to deprotonate the .20 M of acid. Remaining .05 M of acid could not be neutralize and thus
contributing in lowering the pH. Hence, the pH is below 9.3 and indicator turns colorless
indicating more concentration of acid than base..
How is the resistance of a solution is a function of the nature of t.pdf
How is the resistance of a solution is a function of the nature of the substance dissolved in it.
What is conductivity and how is it related to resistance. What is specific conductivity? Please
explain.
Solution
Consider a polar solvent water where the ionic substances or electrolytes get split up into ions
and dissolve in water but the non polar substances do not dissolve in water. Therefore resistance
of a solution depends upon nature of substance dissolved. Conductivity is a degree to which a
specific material gets to conduct electricity. Conductivity is the inverse of resistivity. Specific
conductivity is the measure of ability to which a substance cab conduct electricity on the whole..

Introduction to Quality Improvement Essentials
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.

How to Break the cycle of negative Thoughts
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
