Stress cannot be measured directly, but can be determined indirectly through measuring deformation. When a force is applied to an object, it causes the object to deform through strains, which are fractional changes in length that can be measured directly. For homogeneous, linear elastic, and isotropic materials, stresses and strains are directly related, so by measuring strains, stresses can be determined, although they cannot be measured directly.

Eratosthenes Estimation of the Circumference of the Earth This que.pdf
Eratosthene\'s Estimation of the Circumference of the Earth This question investigates
something that is quite famous and amazing especially for its time. It briefly looks at the work of
Eratosthenes and what he did to estimate the circumference of the Earth. Now perhaps he
idealized the Earth as a perfect sphere to make it easier, but his estimate was pretty close to the
actual, modern value! In your answer, offer commentary and narration regarding what I have
given on the following pages. Please do NOT copy and paste answers and narration from the
Internet! I think YOU (yes YOU there reading this!!) will enjoy this famous mathematical
episode from history. Please make sure that you address and answer ALL questions in this
scenario. Please answer in paragraph form with excellent prose!
Solution
Answer:-
According to the statement
Eratosthenes calculated the circumference of the Earth without leaving Egypt. He knew that at
local noon on the summer solstice in Syene (modern Aswan, Egypt), the Sun was directly
overhead. He knew this because the shadow of someone looking down a deep well at that time in
Syene blocked the reflection of the Sun on the water. He measured the Sun\'s angle of elevation
at noon on the same day in Alexandria. The method of measurement was to make a scale
drawing of that triangle which included a right angle between a vertical rod and its shadow. This
turned out to be 1/50th of a circle. Taking the Earth as spherical, and knowing both the distance
and direction of Syene, he concluded that the Earth\'s circumference was fifty times that
distance.
His knowledge of the size of Egypt was founded on the work of many generations of surveying
trips. Pharaonic bookkeepers gave a distance between Syene and Alexandria of 5,000 stadia (a
figure that was checked yearly)Some say that the distance was corroborated by inquiring about
the time that it took to travel from Syene to Alexandria by camel. Carl Sagan says that
Eratosthenes paid a man to walk and measure the distance. Some claim Eratosthenes used the
Olympic stade of 176.4 m, which would imply a circumference of 44,100 km, an error of
10%,but the 184.8 m Italian stade became (300 years later) the most commonly accepted value
for the length of the stade,which implies a circumference of 46,100 km, an error of 15%. .It was
unlikely, even accounting for his extremely primitive measuring tools, that Eratosthenes could
have calculated an accurate measurement for the circumference of the Earth for three important
assumptions he made (none of which are perfectly accurate):
Eratosthenes later rounded the result to a final value of 700 stadia per degree, which implies a
circumference of 252,000 stadia, likely for reasons of calculation simplicity as the larger number
is evenly divisible by 60.Repeating Eratosthenes\' calculation with more accurate data, the result
is 40,074 km, which is 66 km different (0.16 %) from the currently accepted polar circumference
of the Earth.

Find the derivative of the function y = e^xlnxSolution .pdf
Find the derivative of the function y = e^x/lnx
Solution
y = e^x / ln x is the same thing as y = f(x) / g(x) To find the derivative, use
g(x)f\'(x) - f(x)g\'(x) / g(x)^2 Therefore, (ln x) (e^x) - (e^x)(1/x) / (ln x)^2 f\'(e^x) = e^x g\'(ln
x) = 1/x simplify and get (ln x)(e^x) - (e^x) / x(ln x)^2 or (e^x)(ln x - 1) / x(ln x)^2.
Explain which type of packet, TCP or UDP, is easier to spoof and why.pdf
Explain which type of packet, TCP or UDP, is easier to spoof and why it is easier.
Solution
UDP packets are easier to spoof than TCP packets
Both TCP and UDP are used for sending bits of data called packets.
Whether we’re sending a packet via TCP or UDP, that packet is sent to an IP.
One of the reasons TCP is more secure than UDP is the difficulty in spoofing TCP
communications. TCP is connection oriented – once a connection is established, data can be sent
bidirectional. It is more reliable because it ensures that all segments are received in order and any
lost segments are retransmitted.
UDP spoofing is trivial since there is no notion of connection.UDP is a simpler, connectionless
Internet protocol.Multiple messages are sent as packets in chunks using UDP. UDP does not
guarantee if all segments are received or not. When the connection is bad, UDP segments can get
lost without a trace or arrive in the wrong order.
So, the UDP packets can be easily spoofed than TCP packets..
Ella is a 15-year old high-school freshman. She lives in a small sub.pdf
Ella is a 15-year old high-school freshman. She lives in a small suburban town with her younger
brother, Brody, and her parents, Minka and Bruce. In the past, Ella was always a straight-A
student. She loved school and had many close friends. She was actively involved in cheerleading
and drama club. Ella\'s parents report that over the last 6 months, Ella\'s grades have dropped
significantly. She decided that cheerleading is \"not cool\" and she does not want to be in the
drama club any more. She lost about 15 pounds and is often arguing with her brother and her
family. She does not like to socialize with her friends anymore and is always on the computer but
will not share what she is doing. Ella\'s parents recently reconciled after a 4-month separation.
Bruce was just discharged from a substance-use inpatient center where he was receiving
treatment for alcohol dependence. Her mother carries a diagnosis for anorexia nervosa but has
not displayed any symptoms for 5 years. Both of her parents have been actively engaged in
family counseling and individual therapy as well.
Based on this scenario, answer the following:
What additional information would be helpful for you to effectively form a diagnosis?
What theory of adolescent development would you use to gain an understanding of what is
happening with Ella? Remember, it is often necessary to consider and even apply more than one
theory when working with an adolescent.
How would you compare and contrast the development of Ella\'s issues from a cognitive, social,
and psychodynamic perspective?
Which theory best supports the behaviors that we are currently seeing with Ella?
Solution
The additional information that is required is whethere ella has gone for depression checkups or
has been detected with depression and if she has received therapies.
The theory is the ecological theory which tells about the interaction between indisvisual and the
environment.This is given by URIE BRONFENBRENNER.This theory tells about yow the
adolescents are influenced by family, peers, religion, schools, the media, community, and world
events.
Ella\'s case is the case of depression causes due to social anxiety as she doesnt want to meet
people and her family was seprated for 4 months. She is going through phases but it doesnt
include cognitive anxiety.
The theory of social cognitive learning is very important for her to understand the relations and
society..
Companies and people often buy and sell stocks. Often they buy th.pdf
Companies and people often buy and sell stocks. Often they buy the same stock for different
prices at different times. Say one owns 1000 shares a certain stock (such as Checkpoint), one
may have bought the stock in amounts of 100 shares over 10 different times with 10 different
prices.
We will analyze two different methods of accounting, FIFO and LIFO accounting used for
determining the “cost” of a stock. This is also known as the dollar cost average basis. This
information is typically calculated when a stock is sold to determine if a profit or loss was made.
In our version of FIFO accounting, the price of a commodity is averaged starting with the first
purchase of that item. Say we sell 250 shares of a stock, according to this method the dollar cost
averaged purchase price is determined by averaging the prices on the first 250 shares bought. In
our version of LIFO accounting, the price of a commodity is averaged starting with the last
purchase of that item. Say we sell 250 shares of a stock, according to this method the dollar cost
average purchase price is determined by averaging the prices on the last 250 shares bought.
In this assignment, you will be using a queue for storing data for FIFO accounting, and a stack
for LIFO accounting. Implement your queue using Link list and implement your stack using the
stack class in java.util. Make sure you use the stack and queue abstract data types (ADT) defined
for stacks and queues. Both your stack and queue should have records with the following fields:
The stock Ticker symbol (a string).
The stock Ticker symbol (a string).
The number of shares of a stock (an int
The purchase price for those shares (decimal).
You can assume that the first element of the structure is the security bought first, the second was
bought second, etc.
Your program should have the user able to enter information about various stocks, the amount of
shares, and the price. The user can then enter a query about a certain stock and the cost according
to the LIFO and FIFO accounting methods for a certain number of shares.
The following could be your menu:
Press 1 to enter a new stock
Press 2 to find the LIFO and FIFO dollar cost average for the number of shares sold.
If 1 is pressed, the user needs to enter the stock symbol, Stock name, the number of shares
bought, and the price per share when purchased.
If 2 is pressed, the user needs to enter the stock symbol being queried and the number of shares
you wish to sell. Once that information is entered the dollar cost averaged price per share for
both the LIFO method and the FIFO method should be displayed.
Implement the program described above using the Java programming language to meet the
overall requirements described above. Use the blow data.

What are ways in which brands cut through advertising clutter?
Solution
brand may be anything which is used to distingwish their product/ service from its competitiors\'.
a brand may be a letter,symbol, slogan, photo, caption or combination of any of these.
advertising clutter is the process where it focusses on exposing many advertising messages to
customers. Marketing clutter refers to the normally excessive amount of ad messages consumers
are exposed to on a daily basis. To cut through the clutter, you must try to find the right time and
place to connect with target customers and deliver impacting, creative messages for business.
the different forms are: print clutter, broadcast clutter, mailers and handouts..

Solution
Voluntry response involve the brain, control movement via sending out the motor impulse and it
is voluntry in nature For example, any person uses sight to walk straight. but reflex action is a
response is a involuntry response and cannot be controled for example any person removes its
hand immediately after touching any hot suraface.
In voluntry response the motor signals are initiated by known thoughts and it sensory stimuli
response. reflex response cannot be initiated by previous thoughts and the stimulus of reflex
response signal travels along a sensory nerve to the spinal cord and the sognal comes back via of
a motor nerve
Most of the reflex signals could be processed in the spine with some exception.
voluntry stimulation is initiated at Cerebral cortex of the Brain.The singal travels from cerebral
cortex to the spinal cord.
Reflex action initiated by stimulation of receptor present on skin and dendrites and sensory
neurons are responsible for the travelling of impulse to the central spinal cord..

we are interested in comparing the mean costs of electrical energy produced by nuclear and coal
powered electrical power plants. Pilot studies have indicated the variation in the costs associated
with the two types of plants are sn= $.224 and sc= $ .20.How many plants of each type should be
sampled in order to estimate the difference mean costs with a 95% confidence interval to within
$.01?
Solution
sn = 0.224 and sc = 0.20
Let sample sizes be n1 and n2
SE = 0.224/rtn1 + 0.20/rtn2
Margin of error = z alpha/2 (SE)
For 95% z = 1.96
Hence 1.96(0.224/rtn1 + 0.20/rtn2) = 0.01
As there is one equation and two variables assume n1 = n2
Then we have
0.424/rtn1 = 0.01/1.96 = 0.0051
Or rt n1 = 8.313
n1 =69.111
or n >70 for each sample..

pine tree-sporophyte.Pine trees are conifers (cone bearing) and carry both male and female
sporophylls on the same mature sporophyte.Therefore,they are monoecious plants.
pine cone -gametophyte.In the male cones(staminate cones),the microsporocytes give rise to
pollen grains by meiosis.Female cones (ovulate cones) contain two ovules per scale.One
megaspore mother cell undergoes meiosis in each ovule.Three of the four cells break down
leaving only a single surviving cell which will develop into a female multicellular
gametophyte.It encloses archegonia.Each archegonium contains an egg.
deciduous leafy plants-sporophyte

Solution
Introduction
A Stake is any interest, share, or claim that a group or individual has in the outcome of a
corporation’s policies, procedures, or actions toward others. Stakes may be based on any type of
interest.
Stake Holders :
The stakes of stakeholders are not always obvious. The economic viability of competing firms
can be at stake when one firm threatens entry into a market.
A Stake holder is any individual or group who can affect or is affected by the action, decision,
policies, practices or goals of the organization,”
We begin by identifying the focal stake holder. This is the company or group that is the
focus or central constituency of an analysis.
There are three types of General environment, Task environment, Internal environment.
General Environment:
In general environment, stake holders of organizations, is comprised of economic, legal-political,
technological, socio - cultural and natural environment conditions. Managers must be concerned
about economic conditions in the general environment, particularly those that influence customer
spending, resource supplies, and investment capital.
Internal Environment:
The primary stakeholders of a firm are owners, customers, employees an suppliers comes under
in internal environment, Primary importance to a firm’s survival are its stock holders and board
of directors. The CEO and other top level executives can be stake holders, but in the stake
holder analysis they are generally considered actors and representatives of the firm.BP’s
CEO and top - level team are focal stakeholders. A fully developed internal analysis includes a
broader evaluation of all of the organization’s resources and capabilities to determine strengths,
weaknesses, and opportunities for competitive advantage, and to identify organizational threats
should be corrected.
Task environment:
Secondary stakeholders include all other interested groups, such as the media, consumers,
lobbyists, courts, government, competitors, the public, and society are comes under in task
environment. It involves evaluation of the broad and task environment to determine trends,
threats, and opportunities and to provide a foundation for strategic direction.
The broad environment consists of domestic and global environmental forces such as social -
cultural, technological, political, and economic trends. The broad environment forms the
context within which the firm and its task environment. The task environment consists of
external stake holders.

Prior to 1950, the death rate was high, which kept the numbers of hum.pdf
Prior to 1950, the death rate was high, which kept the numbers of humans from increasing
rapidly. In the 19th Century, the agricultural revolution increased food production. The industrial
revolution improved methods of transporting food and other good. In the 20th Century, advances
in medicine, sanitation and nutrition have decreased the death rates further. These factors
combined to produce the rapid growth of the human population in the 20th century. As with any
population, humans are also limited by factors such as space, amount of food and disease. The
carrying capacity is the number of individuals that a stable environment can support. Authorities
disagree on the maximum number of people that the earth can support, though the numbers
generally range for 8 to 10 billion. As the population approaches its limit, starvation will
increase. Some countries have a much higher growth rate than other. Growth rate is the number
of people born minus the number of people that die. Compare the growth rates of the following
countries. Most countries are trying to reduce their growth rate. Zero population growth means
that as many people are being born as there are dying - to achieve zero population growth, each
couple would need to have no more two children (to replace the parents). Even if this number is
achieved, the population will continue to grow because the parents will still live on for decades,
as their children have children and their children have children and so forth. The United States
reached zero population growth in the 1980\'s, and yet the overall population of the US still
increases. Analysis: What factors contributed to the world\'s overall population growth in the
last 150 years, Why does a population not level off during the same year it reaches zero
population growth? If the carrying capacity of the earth was 9 billion people, when would this
number be reached (according to your graph)? What will happen when the human population
exceeds the earth\'s carrying capacity?
Solution
1. The agricultural revolution led to an increase in the food production.Through industrial
revolution the methods of transporting food and other goods were improved.Advances in
medicine,nutrition and sanitation decreased the death rate among individuals.All these factors led
to increase in the world population in the last 150 years.
2. The population does not level off once zero population growth is achieved because the parents
of the children will continue to live for many more years.Once the children will become parents
they will also continue to live ,so the population is not levelled even if zero population growth is
observed because of the survival of the parets for many more years.
3. The carrying capacity of 9 billion people will be reached by 2030-2040.
4. When the human population exceeds the carrying capacity starvation will take place.People
would fight over the limited resources,which would lead to increase in death rate..

Please explain this in detail. Thank you.
1. How would you test whether or not a species is capable of and uses chemotaxis?
2. How would you test whether or not a trait is cooperative? why?
3. Do you think that group selection affects evolution of natural populations? Why or why not?
4. Do you think that group selection affects evolution of natural populations? Why or why not?
Solution
Ques-1: How would you test whether or not a species is capable of and uses chemotaxis?
The movement of anyt species towards a substance where higher concentration of substance is
located therefore it can be examined this chemotaxis behaviors of any bacteria or eukaryote
based on \"chemotaxis assays\" (Agar-plate techniques or two chmber Boyden plate techniques)
choosing the chemoattractant and chemorepellent features of selected chemicals character of
ligands. The chemotxis can be examined based on the species migration towards the
chemoattractant & motility can be examined by surface colonization.
For instance, chemotaxis: CheY is a phosphoprotein that predominantly utilizes intermediary
metabolites. These metabolites are including, carbamoyl associated phosphate donors
responsible for chemoattrcat properties & promote migration of species towards it. CheY possess
solely a regulatory domain with a specific structure that is a/B followed by having a 5-stranded
parallel with 5 helices of 8 sheets. Bacterial flagellar-containing species are attracted to amino
acid such for instance CheY possess a single individual tryptophan thereby it can produce
structural conformational change at Trp-58 that is adjacent to the site of phosphorylation, Asp-
57..

4. Discuss the features of different types of advanced materials wit.pdf
4. Discuss the features of different types of advanced materials with examples
Solution
Answere: Advanced materials are divided according to the there material properties and
applications.
Solid materials have been conveniently grouped into three basic classifications:
1.Metals,
2.Ceramics, and
3.Polymers.
viz. semiconductors, biomaterials, automobile,smart materials, and nanoengineered materials;
Examples include electronic equipment (camcorders, CD/DVD players, etc.), computers, fiber-
optic systems, Aero spacecraft, aircraft, and military rockets.
Semiconductors
Semiconductors have electrical properties that are intermediate between the eletrical conductors
(viz. metals and metal alloys) and insulators (viz. ceramics and polymers). Furthermore, the
electrical characteristics of these materials are extremely sensitive to the presence of minute
concentrations of impurity atoms, for which the oncentrations may be controlled over very small
spatial regions. Semiconductors have made possible the advent of integrated circuitry that has
totally revolutionized the electronics and computer industries (not to mention our lives) over the
past three decades.
Biomaterials
Biomaterials are employed in components implanted into the human body for replacement of
diseased or damaged body parts.These materials must not produce toxic substances and must be
compatible with body tissues (i.e., must not cause adverse biological reactions). All of the above
materials—metals, ceramics, polymers,composites, and semiconductors—may be used as
biomaterials.
Materials of the Future:
Smart Materials
Smart (or intelligent) materials are a group of new and state-of-the-art materials now being
developed that will have a significant influence on many of our technologies.The adjective
“smart” implies that these materials are able to sense changes in their environments and then
respond to these changes in predetermined manners—traits that are also found in living
organisms. In addition, this “smart” concept is being extended to rather sophisticated systems
that consist of both smart and traditional materials. Actuators may be called upon to change
shape, position, natural frequency, or mechanical characteristics in response to changes in
temperature, electric fields, and/or magnetic fields.
Four types of materials are commonly used for actuators: shape memory alloys, piezoelectric
ceramics, magnetostrictive materials, and electrorheological/magnetorheological fluids.
For example, one type of smart system is used in helicopters to reduce aero-dynamic cockpit
noise that is created by the rotating rotor blades. Piezoelectric sensors inserted into the blades
monitor blade stresses and deformations; feedback signals from these sensors are fed into a
computer-controlled adaptive device,which
generates noise-canceling antinoise.
Nano engineered Materials
Until very recent times the general procedure utilized by scientists to understand the chemistry
and physics of materials has bee.

with the two types of plants are sn= $.224 and sc= $ .20.How many plants of each type should be
sampled in order to estimate the difference mean costs with a 95% confidence interval to within
$.01?
Solution
sn = 0.224 and sc = 0.20
Let sample sizes be n1 and n2
SE = 0.224/rtn1 + 0.20/rtn2
Margin of error = z alpha/2 (SE)
For 95% z = 1.96
Hence 1.96(0.224/rtn1 + 0.20/rtn2) = 0.01
As there is one equation and two variables assume n1 = n2
Then we have
0.424/rtn1 = 0.01/1.96 = 0.0051
Or rt n1 = 8.313
n1 =69.111

1. The agricultural revolution led to an increase in the food production.Through industrial
revolution the methods of transporting food and other goods were improved.Advances in
medicine,nutrition and sanitation decreased the death rate among individuals.All these factors led
to increase in the world population in the last 150 years.
2. The population does not level off once zero population growth is achieved because the parents
of the children will continue to live for many more years.Once the children will become parents
they will also continue to live ,so the population is not levelled even if zero population growth is
observed because of the survival of the parets for many more years.
3. The carrying capacity of 9 billion people will be reached by 2030-2040.
4. When the human population exceeds the carrying capacity starvation will take place.People
would fight over the limited resources,which would lead to increase in death rate..

1. How would you test whether or not a species is capable of and uses chemotaxis?
2. How would you test whether or not a trait is cooperative? why?
3. Do you think that group selection affects evolution of natural populations? Why or why not?
4. Do you think that group selection affects evolution of natural populations? Why or why not?
Solution
Ques-1: How would you test whether or not a species is capable of and uses chemotaxis?
The movement of anyt species towards a substance where higher concentration of substance is
located therefore it can be examined this chemotaxis behaviors of any bacteria or eukaryote
based on \"chemotaxis assays\" (Agar-plate techniques or two chmber Boyden plate techniques)
choosing the chemoattractant and chemorepellent features of selected chemicals character of
ligands. The chemotxis can be examined based on the species migration towards the
chemoattractant & motility can be examined by surface colonization.
For instance, chemotaxis: CheY is a phosphoprotein that predominantly utilizes intermediary
metabolites. These metabolites are including, carbamoyl associated phosphate donors
responsible for chemoattrcat properties & promote migration of species towards it. CheY possess
solely a regulatory domain with a specific structure that is a/B followed by having a 5-stranded
parallel with 5 helices of 8 sheets. Bacterial flagellar-containing species are attracted to amino
acid such for instance CheY possess a single individual tryptophan thereby it can produce
structural conformational change at Trp-58 that is adjacent to the site of phosphorylation, Asp-
57..

4. Discuss the features of different types of advanced materials wit.pdf
4. Discuss the features of different types of advanced materials with examples
Solution
Answere: Advanced materials are divided according to the there material properties and
applications.
Solid materials have been conveniently grouped into three basic classifications:
1.Metals,
2.Ceramics, and
3.Polymers.
viz. semiconductors, biomaterials, automobile,smart materials, and nanoengineered materials;
Examples include electronic equipment (camcorders, CD/DVD players, etc.), computers, fiber-
optic systems, Aero spacecraft, aircraft, and military rockets.
Semiconductors
Semiconductors have electrical properties that are intermediate between the eletrical conductors
(viz. metals and metal alloys) and insulators (viz. ceramics and polymers). Furthermore, the
electrical characteristics of these materials are extremely sensitive to the presence of minute
concentrations of impurity atoms, for which the oncentrations may be controlled over very small
spatial regions. Semiconductors have made possible the advent of integrated circuitry that has
totally revolutionized the electronics and computer industries (not to mention our lives) over the
past three decades.
Biomaterials
Biomaterials are employed in components implanted into the human body for replacement of
diseased or damaged body parts.These materials must not produce toxic substances and must be
compatible with body tissues (i.e., must not cause adverse biological reactions). All of the above
materials—metals, ceramics, polymers,composites, and semiconductors—may be used as
biomaterials.
Materials of the Future:
Smart Materials
Smart (or intelligent) materials are a group of new and state-of-the-art materials now being
developed that will have a significant influence on many of our technologies.The adjective
“smart” implies that these materials are able to sense changes in their environments and then
respond to these changes in predetermined manners—traits that are also found in living
organisms. In addition, this “smart” concept is being extended to rather sophisticated systems
that consist of both smart and traditional materials. Actuators may be called upon to change
shape, position, natural frequency, or mechanical characteristics in response to changes in
temperature, electric fields, and/or magnetic fields.
Four types of materials are commonly used for actuators: shape memory alloys, piezoelectric
ceramics, magnetostrictive materials, and electrorheological/magnetorheological fluids.
For example, one type of smart system is used in helicopters to reduce aero-dynamic cockpit
noise that is created by the rotating rotor blades. Piezoelectric sensors inserted into the blades
monitor blade stresses and deformations; feedback signals from these sensors are fed into a
computer-controlled adaptive device,which
generates noise-canceling antinoise.
Nano engineered Materials
Until very recent times the general procedure utilized by scientists to understand the chemistry
and physics of materials has bee.

Create all!! Code Using Doubly Linked List In this project, you should write a simple line editor.
Keep the entire text on a linked list, one line in a separate node. Stan the program with entering
EDIT file, after which a prompt appeals along with the line number. If the letter I is entered with
a number n following it. then insert the text to be followed before line n. If I is not followed by a
number, then insert the text before the current line. If D is entered with two numbers n1 and m.
one n. or no member following it. then delete lines 11 through 111. line 11. or the current line.
Do the same with the command L. which stands for listing lines. If A is entered, then append the
text to the existing lines. Entry E signifies exit and saving the text in a file. Here is an Example:
Solution

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.

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.

Can we measure stress directlySolutionStress is defined as in.pdf
- 1. Can we measure stress directly? Solution Stress is defined as internal resisting force per unit area. When we apply a force to an object then object is deformed then we can say that forces produces strains (fractional change in length) Hence Deformation can be measured directly and no need of other physical quantities required to measured deformation in object. Hence, they are primary function. We know that strains and stresses are directly related to each other for homogeneous, linear elastic and isotropic materials. Hence we can not measure stress directly.
