In this first module we have explored the historical ideas of the na.pdf
In this first module we have explored the historical ideas of the nature of the Universe. In the
days of Ptolemy and Copernicus, the Universe was all things, so the question of the whether the
Sun went round the Earth or the Earth went round the Sun was a question about the nature of the
Universe. Of course today, being citizens of the 21st Century, the question is moot, the Earth
goes round the Sun, and there is lots of stuff beyond the Solar System that makes up the
Universe. But, where does this idea come from, and what is the evidence supporting
it?
For this first forum we will investigate this question in two parts.
For the first post, due Friday, 1/22 by 11pm, try to organize a response to the questions:
Does the Earth revolve around the Sun?
How do you know?
What is the evidence supporting your answer?
Solution
For some time after it was accepted that planets (including Earth) circle the Sun, there was no
direct proof that it is Earth that moves, and not the Sun.
Ancient astronomer Aristarchus thought that Earth goes around the Sun since he discovered that
the Sun is much bigger than Earth. Copernicus (who is usually credited with the idea that planets
go around the Sun) thought that Solar system centered on the Sun is more logical and beautiful,
but had no definite proof. Kepler discovered that laws governing of orbits become much more
simple if the Sun is in their center. Newton has shown that this is caused by the universal law of
gravity. If gravity works, Earth and other planets have to go around the Sun, because it is much
heavier.
There was no straightforward proof for the motion of Earth until 1725 when James Bradley
discovered stellar aberration. This is (apparent) yearly change in positions of all stars in the sky
due to Earth\'s own motion. Aberration arises due to adding up of the speed of light coming from
the star and Earth\'s own speed. This is a very complex phenomenon and its description requires
some math.
Another, much simpler, consequence of Earth\'s motion is stellar parallax. If Earth changes its
position relative to the stars, then the stars should appear to change position in the course of the
year.
A common experiment illustrating parallax is just looking at a close object (a finger, a pencil etc)
with one eye at the time. When you switch from one to the other eye, the object will appear to
move against the background. Closer the object is to your eyes, more pronounced the effect is.
Parallax should not be confused with aberration: parallax arises from the change of Earth\'s
position and depends on the distance to the star, while aberration is caused by Earth\'s great
speed and does not depend on how far the star is.
Parallax of a star was first measured by Bessel in 1838. It was not measured before because this
change of star\'s apparent position is very small (the stars are very far from us). This was a very
important discovery because Aristotle himself mentioned the lack of observable stellar parallax
as the.
If someone says to you, I believe there might be planets around K-.pdf
If someone says to you, \"I believe there might be planets around K-type stars\", how would you
respond? Defend your answer with the formation of the solar system.
Solution
A K-type star is the main sequence star on an HR-digram because the they are hydrogen-burning
stars. K-type stars usually weigh around 0.45 to 0.8 solar masses, and they have a surface
temperature of 3,900 and 5,200 K, they live on the main sequence for a very long time
approximately 15 to 30 billion years. Researchers believe that the solar system was formed from
a cloud of gas and dust in space was perturbed, maybe by the explosion of a nearby star. This
explosion made waves in space which compressed the cloud of gas and dust. Compressing made
the cloud start to collapse under its on gravity, a, forming a solar nebula. Just like an Ice-skater
that spins faster as she pulls in her arms, the cloud begins to spin as it collapses. Eventually, the
cloud grows hotter and denser in the center, with a disk of gas and dust surrounding it that was
hot in the middle but cool at the edges. As the disk got thinner and thinner, particles began to pile
together and form clumps. Some clumps got bigger, as particles and small clumps stuck to them,
eventually forming planets or moons. Near the center of the cloud, where planets likeEarth
formed, the only rocky material could stand the great heat. Icy matter settled in the outer regions
of the disk along with rocky material, where the giant planets likeJupiter formed. As the cloud
continued to fall in, the center eventually got so hot that it became a star, the Sun, and blew most
of the gas and dust of the new solar system with a strong stellar wind. By studying meteorites,
which are thought to be left over from this early phase of the solar system, scientists have found
that the solar system is about 4600 million years old. A K-type star will need similar conditions
to form it self and the debris form the star formation can lead to the formation of planets..

Explain how a SYN flood attack works.
Solution
An attacker would send an initial request asking for acknowledgment from the receiving server.
The receiving server would place this in a line with recognizing information, using a small
amount of memory and resources to do so. The server would look forward to a fast return from
its acknowledgment but the attacker would not do so or just not react. The server would wait for
a predefined timeout stage to reject the connection request..

Time invariant systems means whose response remains constant even the time changes.
Hence given cascaded response will be also Have Time invariant response..
By using MIMO technique, the throughput can be increased greatly wit.pdf
By using MIMO technique, the throughput can be increased greatly without increasing the signal
power and channel bandwidth.
Solution
It is a True statement.Spatial multiplexing enables a MIMO transmitter/receiver pair to increase
its throughput without increasing bandwidth usage or transmit power. Multiplexing increases
throughput linearly with the number of transmit or receive antennas whichever is lower. The
transmitter sends signals carrying different bit streams from each of its antennas. Each receiver
antenna receives a linear combination of the transmitted signals.

Transport layer is the fourth layer in the OSI reference model. The main function of the transport
layer is it acts as a bridge between two layers that is the third layer application layer which
transport layer takes some packets from application layers and breaks it in to some sub parts and
send those to the next one that is network layer. It maintaions the same sequence without any
disturbance and mainly folows the order. The packets which are taken from the upper layer that
is application layer in the form of segments. The application layer makes use of the transport
layer because these are the host layers. Application layer defines TCP/IP application protocols

why?
2. From the measured value of CS potential in tap water, determine whether it corrodes or not,
knowing
that E0(Fe/Fe+2) = - 440 mV vs. Standard Hydrogen Electrode (SHE.).
3. CS in tap water develops different potential from that of CS in brine. Explain why?
4. Are the measured values of potential (E0) for Zn / Zn+2 and Cu / Cu+2 under standard
conditions same as those given in the text book? If Not, explain why?
5. What happens to E if metal ion concentration decreases. Explain why?
Solution
SOlution
1) Carbon steel is made up of iron and carbon while stainless steel is made up of chormium and
iron . So reduction potential of two alloys are different based on the metals used.
2) The reduction potential of CS is less than that of hydrogen, so it will be more reactive or more
prone to oxidation and will corrode.
3) Due to difference in the enviroment the tendency to undergo oxidation or reduction changes.
In water we are considering only hydrogen reduction while in brine salts are also included.
4) They are not exactly same , might me due to some erroe in measurements or due to difference
in temperature conditions.Since, standard reduction potential depends upon the temperature,
pressure and concentration
5) decreaing the concentration of metal ion will decrease the value of potential of cell(E) ..

a) Meiosis results in the production of four daughter cells(sperm or egg) with half the number of
chromosomes from the original cell and mitosis results in the production of two daughter cells
identical to the original cell.
Mitosis takes place in the somatic cells of the body and the meiosis takes place in the sexual
reproductive cells or the \'germ cells\' of the body. In mitosis, the cells divide once resuting in
two daughter cells having same number of chromosome as parent cell. The genetic constitution
of the daughter cell as identical to parent cell. In meiosis there are two cell divisions resuting in
four daughter cells having half the number of chromosomes as parent cell (reduced from diploid
to haploid). The genetic constituion of the daughter cell is different from parent cell..

What are some invasive species on the Hawaii islands. When and howw.pdf
What are some invasive species on the Hawaii islands. When and how/why were they
introduced? What impact have they had? 100 words or more please.
Solution
Hawaii has been invaded by a number of invasive species – both plants and animals. Some of the
invasive species and their effects are,
Rosy wolf snail (Euglandina rosea) – introduced to control the African snails, which are an
agricultural pest, the Rosy wolf snail has destroyed the native snails of Hawaii. It has eliminated
up to half of the 800 endemic species of snails in Hawaii
Miconia (Miconia calvescens) – introduced as an ornamental plant, it forms dense thickets that
blocks sunlight and kills other plants
Fountain grass (Pennisetum setaceum) – it is a highly aggressive species that is more vigorous
than the native plants. It quickly reestablishes after fire and alters the natural fire regime
Fire tree (Myrica faya) – it forms dense monocultural stands. As a result it poses threat to native
plants especially on young volcanic sites and lowland forests. It was introduced as an ornamental
and as firewood plant.
Guava (Psidium gujava) – introduced for edible fruit cultivation. It forms dense thickets and
poses threats to the native flora and fauna of Hawaii.
Mongoose – it was introduced to kill large rat population present in the sugarcane fields of
Hawaii. If failed to kill the rats but harms the ground nesting birds on the island..

I had this experience once when we were implementing quality improvement in an organization.
Our organization has been recently merged with another entity. These two entities have different
systems. When we designed a questionnaire to system owners, we devised it on the basis of
systems of our original unit and for the other unit , we didnot put extra effort and devises
standard questions for them. This led to incorrect results that investment of X amount is
sufficient to improve performance by Y. In actually, the performance of our unit has improved
by Y but the overall organization performance improved by 10% of Y only as other units
performance reduced due to this recommendations..

The final electron acceptor(s) associated with photosystem II is/are:
Solution
The final electron acceptor associated with photosystem II is \"ADP\".
The PS II pigment complex absorbs solar energy; high-energy electrons (e-) leave the reaction-
center chlorophyll a molecule. PS II takes replacement electrons from H2O, which splits,
releasing O2 and H+ ions.Oxygen is released as oxygen gas (O2). The H+ ions temporarily stay
within the thylakoid space and contribute to a H+ ion gradient. As H+ flow down
electrochemical gradient through ATP synthase complexes, chemiosmosis occurs.
State the principles of management as enumerated by Henry Fayol. Exp.pdf
State the principles of management as enumerated by Henry Fayol. Explain any eight of them?
Solution
14 principles of Management are statements that are based on a fundamental truth. These
principles of management serve as a guideline for decision-making and management actions.
They are drawn up by means of observations and analyses of events that managers encounter in
practice. Henri Fayol was able to synthesize 14 principles of management after years of study,
namely:
1. Division of Work
In practice, employees are specialized in different areas and they have different skills. Different
levels of expertise can be distinguished within the knowledge areas (from generalist to
specialist). Personal and professional developments support this. According to Henri Fayol
specialization promotes efficiency of the workforce and increases productivity. In addition, the
specialization of the workforce increases their accuracy and speed. This management principle of
the 14 principles of management is applicable to both technical and managerial activities.
2. Authority and Responsibility
In order to get things done in an organization, management has the authority to give orders to the
employees. Of course with this authority comes responsibility. According to Henri Fayol, the
accompanying power or authority gives the management the right to give orders to the
subordinates. The responsibility can be traced back from performance and it is therefore
necessary to make agreements about this. In other words, authority and responsibility go together
and they are two sides of the same coin.
3. Discipline
This third principle of the 14 principles of management is about obedience. It is often a part of
the core values of a mission and vision in the form of good conduct and respectful interactions.
This management principle is essential and is seen as the oil to make the engine of an
organization run smoothly.
4. Unity of Command
The management principle ‘Unity of command’ means that an individual employee should
receive orders from one manager and that the employee is answerable to that manager. If tasks
and related responsibilities are given to the employee by more than one manager, this may lead
to confusion which may lead to possible conflicts for employees. By using this principle, the
responsibility for mistakes can be established more easily.
5. Unity of Direction
This management principle of the 14 principles of management is all about focus and unity. All
employees deliver the same activities that can be linked to the same objectives. All activities

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.

What are the main responsibilities of the Transport Layer? What are the main services provided
by the Transport Layer to the Application Layer?
Solution
Transport layer is the fourth layer in the OSI reference model. The main function of the transport
layer is it acts as a bridge between two layers that is the third layer application layer which
transport layer takes some packets from application layers and breaks it in to some sub parts and
send those to the next one that is network layer. It maintaions the same sequence without any
disturbance and mainly folows the order. The packets which are taken from the upper layer that
is application layer in the form of segments. The application layer makes use of the transport
layer because these are the host layers. Application layer defines TCP/IP application protocols
and how host programs interface with Transport layer services to use the network..

1. CS in tap water develops different potential from that of SS in same environment. Explain
why?
2. From the measured value of CS potential in tap water, determine whether it corrodes or not,
knowing
that E0(Fe/Fe+2) = - 440 mV vs. Standard Hydrogen Electrode (SHE.).
3. CS in tap water develops different potential from that of CS in brine. Explain why?
4. Are the measured values of potential (E0) for Zn / Zn+2 and Cu / Cu+2 under standard
conditions same as those given in the text book? If Not, explain why?
5. What happens to E if metal ion concentration decreases. Explain why?
Solution
SOlution
1) Carbon steel is made up of iron and carbon while stainless steel is made up of chormium and
iron . So reduction potential of two alloys are different based on the metals used.
2) The reduction potential of CS is less than that of hydrogen, so it will be more reactive or more
prone to oxidation and will corrode.
3) Due to difference in the enviroment the tendency to undergo oxidation or reduction changes.
In water we are considering only hydrogen reduction while in brine salts are also included.
4) They are not exactly same , might me due to some erroe in measurements or due to difference
in temperature conditions.Since, standard reduction potential depends upon the temperature,
pressure and concentration
5) decreaing the concentration of metal ion will decrease the value of potential of cell(E) ..

4. The difference between meiosis and mitosis.
a) Meiosis results in the production of four daughter cells(sperm or egg) with half the number of
chromosomes from the original cell and mitosis results in the production of two daughter cells
identical to the original cell.
Mitosis takes place in the somatic cells of the body and the meiosis takes place in the sexual
reproductive cells or the \'germ cells\' of the body. In mitosis, the cells divide once resuting in
two daughter cells having same number of chromosome as parent cell. The genetic constitution
of the daughter cell as identical to parent cell. In meiosis there are two cell divisions resuting in
four daughter cells having half the number of chromosomes as parent cell (reduced from diploid
to haploid). The genetic constituion of the daughter cell is different from parent cell..

What are some invasive species on the Hawaii islands. When and howw.pdf
What are some invasive species on the Hawaii islands. When and how/why were they
introduced? What impact have they had? 100 words or more please.
Solution
Hawaii has been invaded by a number of invasive species – both plants and animals. Some of the
invasive species and their effects are,
Rosy wolf snail (Euglandina rosea) – introduced to control the African snails, which are an
agricultural pest, the Rosy wolf snail has destroyed the native snails of Hawaii. It has eliminated
up to half of the 800 endemic species of snails in Hawaii
Miconia (Miconia calvescens) – introduced as an ornamental plant, it forms dense thickets that
blocks sunlight and kills other plants
Fountain grass (Pennisetum setaceum) – it is a highly aggressive species that is more vigorous
than the native plants. It quickly reestablishes after fire and alters the natural fire regime
Fire tree (Myrica faya) – it forms dense monocultural stands. As a result it poses threat to native
plants especially on young volcanic sites and lowland forests. It was introduced as an ornamental
and as firewood plant.
Guava (Psidium gujava) – introduced for edible fruit cultivation. It forms dense thickets and
poses threats to the native flora and fauna of Hawaii.
Mongoose – it was introduced to kill large rat population present in the sugarcane fields of
Hawaii. If failed to kill the rats but harms the ground nesting birds on the island..

I had this experience once when we were implementing quality improvement in an organization.
Our organization has been recently merged with another entity. These two entities have different
systems. When we designed a questionnaire to system owners, we devised it on the basis of
systems of our original unit and for the other unit , we didnot put extra effort and devises
standard questions for them. This led to incorrect results that investment of X amount is
sufficient to improve performance by Y. In actually, the performance of our unit has improved
by Y but the overall organization performance improved by 10% of Y only as other units
performance reduced due to this recommendations..

The final electron acceptor(s) associated with photosystem II isare.pdf
The final electron acceptor(s) associated with photosystem II is/are:
Solution
The final electron acceptor associated with photosystem II is \"ADP\".
The PS II pigment complex absorbs solar energy; high-energy electrons (e-) leave the reaction-
center chlorophyll a molecule. PS II takes replacement electrons from H2O, which splits,
releasing O2 and H+ ions.Oxygen is released as oxygen gas (O2). The H+ ions temporarily stay
within the thylakoid space and contribute to a H+ ion gradient. As H+ flow down
electrochemical gradient through ATP synthase complexes, chemiosmosis occurs.
State the principles of management as enumerated by Henry Fayol. Exp.pdf
State the principles of management as enumerated by Henry Fayol. Explain any eight of them?
Solution
14 principles of Management are statements that are based on a fundamental truth. These
principles of management serve as a guideline for decision-making and management actions.
They are drawn up by means of observations and analyses of events that managers encounter in
practice. Henri Fayol was able to synthesize 14 principles of management after years of study,
namely:
1. Division of Work
In practice, employees are specialized in different areas and they have different skills. Different
levels of expertise can be distinguished within the knowledge areas (from generalist to
specialist). Personal and professional developments support this. According to Henri Fayol
specialization promotes efficiency of the workforce and increases productivity. In addition, the
specialization of the workforce increases their accuracy and speed. This management principle of
the 14 principles of management is applicable to both technical and managerial activities.
2. Authority and Responsibility
In order to get things done in an organization, management has the authority to give orders to the
employees. Of course with this authority comes responsibility. According to Henri Fayol, the
accompanying power or authority gives the management the right to give orders to the
subordinates. The responsibility can be traced back from performance and it is therefore
necessary to make agreements about this. In other words, authority and responsibility go together
and they are two sides of the same coin.
3. Discipline
This third principle of the 14 principles of management is about obedience. It is often a part of
the core values of a mission and vision in the form of good conduct and respectful interactions.
This management principle is essential and is seen as the oil to make the engine of an
organization run smoothly.
4. Unity of Command
The management principle ‘Unity of command’ means that an individual employee should
receive orders from one manager and that the employee is answerable to that manager. If tasks
and related responsibilities are given to the employee by more than one manager, this may lead
to confusion which may lead to possible conflicts for employees. By using this principle, the
responsibility for mistakes can be established more easily.
5. Unity of Direction
This management principle of the 14 principles of management is all about focus and unity. All
employees deliver the same activities that can be linked to the same objectives. All activities
must be carried out by one group that forms a team. These activities must be described in a plan
of action. The manager is ultimately responsible for this plan and he monitors the progress of the
defined and planned activities. Focus areas are the efforts made by the employees and
coordination.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
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.
