The balance of payments of a country is a systematic record of all e.pdf
The balance of payments of a country is a systematic record of all economic transactions
between the residents of a country and the rest of the world. BOP presents a classified record of
all receipts on account of goods exported, services rendered and capital received by residents and
payments made by them on account of goods imported and services received from the capital
transferred to non-residents or foreigners.
It adopts a double-entry book-keeping system. It has two sides: credit side and debit side.
Receipts are recorded on the credit side and payments on the debit side.
Current account of BOP
BOP on current account is a statement of actual receipts and payments in short period. It includes
the value of export and imports of both visible and invisible goods. There can be either surplus or
deficit in current account.The current account includes:- export & import of services, interests,
profits, dividends and unilateral receipts/payments from/to abroad. BOP on current account
refers to the inclusion of three balances of namely – Merchandise balance, Services balance and
Unilateral Transfer balance.
Capital Account of BOP
The capital account records all international transactions that involve a resident of the country
concerned changing either his assets with or his liabilities to a resident of another country.
Transactions in the capital account reflect a change in a stock – either assets or liabilities. It is
difference between the receipts and payments on account of capital account. It refers to all
financial transactions. The capital account involves inflows and outflows relating to investments,
short term borrowings/lending, and medium term to long term borrowing/lending.

REITs are Real Estate Investment Trusts. REITs are considered as a unique vehicle for studying
capital structure decisions due to the fact that REITs do not use the conventional models and
approaches like the net income approach or the net operating income approach or the Modigliani
and Miller approach to determine their capital structure. Their capital structure usually exhibits
use of low leverage with use of debt that has longer maturity. REITs maintain a much higher
proportion of fixed rate debt and tend to avoid or reduce its dependence on secured debts. REIT
shuns the use of variable rate debt and there exists an inverse relationship between the value of
REIT and leverage.
Research and empirical studies suggests that the optimal capital structure of REITs is one that
has the highest “q ratio”, low leverage, and higher proportion of fixed rate debts.

AnswerThe given experiment is related to the bacterial transforma.pdf
Answer:
The given experiment is related to the bacterial transformation. Bacterial transformation is the
transfer of foreign genetic material (either DNA or RNA) into the recipient cell through direct
uptake from the environment. It is a process involves exchange of genetic material between of
two organisms through non-reproductive mode in contrast to the traditional reproduction
(vertical transfer through sexual or asexual reproduction). It results to the change in the genotype
of the recipient cell due to incorporation of newly acquired DNA into the recipient genome
through either recombination or insertion.
The transformants can be identified using a selective medium. The identification of the
transformants (containing the vector/foreign molecule) require the presence of a suitable marker
genes on the vector molecule, whose expression provides a means of identifying cells containing
it (transformants). The most popular marker used for it are: a) Antibiotic resistant gene, b) colour
substance developing gene, c) galactosidase gene complementation.
In the given experiment 3 markers were used:
a) The vector (pGLO plasmid) contain the gene for Green Fluorescent Protein (GFP) and the
ampicillin resistance gene (which codes for beta-lactamase). Because it shares a bidirectional
promoter with a gene for metabolizing arabinose, the GFP gene is expressed in the presence of
arabinose, which makes the transgenic organism express its fluorescence under UV light. GFP
can be induced in bacteria containing the pGLO plasmid by growing them on +arabinose plates.
b) Ampicillin antibiotic, inhibits the cell wall synthesis. It acts as a competitive inhibitor of the
enzyme transpeptidase.
c) Arabinose (as a carbon source for bacteria).
The genetic transformation resulting to the change the phenotype of the organism (E. coli in case
of the given experiment). The results found after the transformation experiment would be in
observed in 4 type of plates.
1) Control plate (Growth medium only)
2) Control plate (Growth medium+ampicillin)
3) Transformant plate (Growth medium+ampicillin+pGLO)
4) Transformant plate (Growth medium+ampicillin+pGLO+arabinose)
The observations of control plate (E. coli cells before transformantion experiment) might provide
reference data to determine if any genetic transformation has occurred. Thus, we have to record
the a) Number of colonies, b) Size of the colony, c) Color of the colonies, d) Distribution of the
colonies on the plate, e) Visible appearance when viewed with ultraviolet (UV) light), f) The
ability of the cells to survive and multiply in the presence of an antibiotic ampicillin.
Expected Results:
*Plate 1: The results would obtained that countable (between 30-300), small, circular, shiny,
colourless colonies of E. coli were distributed throught out the plate. They would be non-
fluorescent when obsered under UV-light.
*Plate 2: No colonies will be developed in the presence of ampicillin because the E. coli is non
resistant .

Answer A] Water solventates any substances that .pdf
Answer: A] Water solventates any substances that may dissociate into charged ions.
Taking salt for example (NaCl), the water will allow the solid salt to dissociate into Na+ and Cl-
ions. How does it do this chemically? Water molecules are polar. Hence, they surround the ions
in something called a hydration shell. Water is H2O, the hydrogens have a positive dipole
whereas the oxygen has a negative dipole. The negative sides of the water molecule (oxygen)
will all surround and face the positive charged Na+ ions. The positive sides of the water
molecule (hydrogens) will surround the negatively charged Cl- ions. B] A hydrogen bond is
formed between an hydrogen atom on one molecule and an electronegative atom on another
molecule (oxygen, flourine, nitrogen, etc.). The hydrogen atom on the first molecule must be
covalently binded to an electronegative atom as well. Overall hydrogen bond: O-H...O (dotted
line is the hydrogen bond). In water, these bonds are rapidly formed and destroyed. It is not a
covalent bond, but sort of an interaction force between water molecules. Physically, this may be
seen with ice. Ice forms crystal-like structures due to the neat organization of these hydrogen
interactions. C] Water will tend to isolate hydrophobic substances. Water is polar and hence
likes to mix with other polar substances. Since hydrophobic substances are non-polar, the water
will physically separate out the hydrophobic substances in solution. In chemical terms, the water
will just form clatherates (organized shells of water) around any hydrophobic substance. This can
be seen if you add oil to water. It just doesn\'t mix.

Here some of the reasons why list instead of a vector:
(i) Storing large data, that is if few elements contains more data then it is inefficient in storing
into
vectors. But this can easily done using lists.
(ii) Iterations, insertning and deleting will take more time in vectors comparitively to lists.
(iii) In lists searching and traversing are inconsequential.
(iv) Splice and merge methods are not available in vectors. If we try to do using vectors then
operation will be more expensive.

(1)Through antibiotic resistance, bacteria will resist the action of.pdf
(1)Through antibiotic resistance, bacteria will resist the action of antibiotic and there are
different ways through which bacteria will become antibiotic resistance.
Conjugation: Here the resistant bacteria will transfer genetic material responsible for antibiotic
resistance to another bacterium by forming direct contact with them through sex pilus.
Transduction: The resistance traits of one bacterium will get packed into the head portion of the
virus (bacteriophage) and the release phage progeny from these antibiotic resistant bacteria will
infect susceptible bacteria and transfer the antibiotic resistance genes to them.
Transformation: Here bacteria capable of undergoing transformation will take up short fragments
of naked DNA responsible for antibiotic resistance from the surrounding environment by direct
uptake.
By undergoing genetic mutation: By undergoing genetic mutations, the bacteria will produce
chemicals which will eliminate the action of antibiotics and in some cases the target will be
modified to escape from antibiotic action.
(2) The genetic code is universal and bacterial cell will try to translate the gene to produce the
protein, but the proteins will not similar to human proteins because
Bacteria are lacking splicing mechanism it cannot splice out the introns from exons and thus it
will try to transcribe and translate the gene with both introns and exons giving different proteins.
In addition to this the proteins produced by bacteria will be different form human cells because,
bacteria used 70S ribosomes and the translation it does is different from the human ribosome and
another thing is codon usage is different in bacteria and we will have different genomic tRNA

payments made by them on account of goods imported and services received from the capital
transferred to non-residents or foreigners.
It adopts a double-entry book-keeping system. It has two sides: credit side and debit side.
Receipts are recorded on the credit side and payments on the debit side.
Current account of BOP
BOP on current account is a statement of actual receipts and payments in short period. It includes
the value of export and imports of both visible and invisible goods. There can be either surplus or
deficit in current account.The current account includes:- export & import of services, interests,
profits, dividends and unilateral receipts/payments from/to abroad. BOP on current account
refers to the inclusion of three balances of namely – Merchandise balance, Services balance and
Unilateral Transfer balance.
Capital Account of BOP
The capital account records all international transactions that involve a resident of the country
concerned changing either his assets with or his liabilities to a resident of another country.
Transactions in the capital account reflect a change in a stock – either assets or liabilities. It is
difference between the receipts and payments on account of capital account. It refers to all
financial transactions. The capital account involves inflows and outflows relating to investments,
short term borrowings/lending, and medium term to long term borrowing/lending.

REITs are Real Estate Investment Trusts. REITs are considered as a unique vehicle for studying
capital structure decisions due to the fact that REITs do not use the conventional models and
approaches like the net income approach or the net operating income approach or the Modigliani
and Miller approach to determine their capital structure. Their capital structure usually exhibits
use of low leverage with use of debt that has longer maturity. REITs maintain a much higher
proportion of fixed rate debt and tend to avoid or reduce its dependence on secured debts. REIT
shuns the use of variable rate debt and there exists an inverse relationship between the value of
REIT and leverage.
Research and empirical studies suggests that the optimal capital structure of REITs is one that
has the highest “q ratio”, low leverage, and higher proportion of fixed rate debts.

AnswerThe given experiment is related to the bacterial transforma.pdf
Answer:
The given experiment is related to the bacterial transformation. Bacterial transformation is the
transfer of foreign genetic material (either DNA or RNA) into the recipient cell through direct
uptake from the environment. It is a process involves exchange of genetic material between of
two organisms through non-reproductive mode in contrast to the traditional reproduction
(vertical transfer through sexual or asexual reproduction). It results to the change in the genotype
of the recipient cell due to incorporation of newly acquired DNA into the recipient genome
through either recombination or insertion.
The transformants can be identified using a selective medium. The identification of the
transformants (containing the vector/foreign molecule) require the presence of a suitable marker
genes on the vector molecule, whose expression provides a means of identifying cells containing
it (transformants). The most popular marker used for it are: a) Antibiotic resistant gene, b) colour
substance developing gene, c) galactosidase gene complementation.
In the given experiment 3 markers were used:
a) The vector (pGLO plasmid) contain the gene for Green Fluorescent Protein (GFP) and the
ampicillin resistance gene (which codes for beta-lactamase). Because it shares a bidirectional
promoter with a gene for metabolizing arabinose, the GFP gene is expressed in the presence of
arabinose, which makes the transgenic organism express its fluorescence under UV light. GFP
can be induced in bacteria containing the pGLO plasmid by growing them on +arabinose plates.
b) Ampicillin antibiotic, inhibits the cell wall synthesis. It acts as a competitive inhibitor of the
enzyme transpeptidase.
c) Arabinose (as a carbon source for bacteria).
The genetic transformation resulting to the change the phenotype of the organism (E. coli in case
of the given experiment). The results found after the transformation experiment would be in
observed in 4 type of plates.
1) Control plate (Growth medium only)
2) Control plate (Growth medium+ampicillin)
3) Transformant plate (Growth medium+ampicillin+pGLO)
4) Transformant plate (Growth medium+ampicillin+pGLO+arabinose)
The observations of control plate (E. coli cells before transformantion experiment) might provide
reference data to determine if any genetic transformation has occurred. Thus, we have to record
the a) Number of colonies, b) Size of the colony, c) Color of the colonies, d) Distribution of the
colonies on the plate, e) Visible appearance when viewed with ultraviolet (UV) light), f) The
ability of the cells to survive and multiply in the presence of an antibiotic ampicillin.
Expected Results:
*Plate 1: The results would obtained that countable (between 30-300), small, circular, shiny,
colourless colonies of E. coli were distributed throught out the plate. They would be non-
fluorescent when obsered under UV-light.
*Plate 2: No colonies will be developed in the presence of ampicillin because the E. coli is non
resistant .

Answer A] Water solventates any substances that .pdf
Answer: A] Water solventates any substances that may dissociate into charged ions.
Taking salt for example (NaCl), the water will allow the solid salt to dissociate into Na+ and Cl-
ions. How does it do this chemically? Water molecules are polar. Hence, they surround the ions
in something called a hydration shell. Water is H2O, the hydrogens have a positive dipole
whereas the oxygen has a negative dipole. The negative sides of the water molecule (oxygen)
will all surround and face the positive charged Na+ ions. The positive sides of the water
molecule (hydrogens) will surround the negatively charged Cl- ions. B] A hydrogen bond is
formed between an hydrogen atom on one molecule and an electronegative atom on another
molecule (oxygen, flourine, nitrogen, etc.). The hydrogen atom on the first molecule must be
covalently binded to an electronegative atom as well. Overall hydrogen bond: O-H...O (dotted
line is the hydrogen bond). In water, these bonds are rapidly formed and destroyed. It is not a
covalent bond, but sort of an interaction force between water molecules. Physically, this may be
seen with ice. Ice forms crystal-like structures due to the neat organization of these hydrogen
interactions. C] Water will tend to isolate hydrophobic substances. Water is polar and hence
likes to mix with other polar substances. Since hydrophobic substances are non-polar, the water
will physically separate out the hydrophobic substances in solution. In chemical terms, the water
will just form clatherates (organized shells of water) around any hydrophobic substance. This can
be seen if you add oil to water. It just doesn\'t mix.

Transformation: Here bacteria capable of undergoing transformation will take up short fragments
of naked DNA responsible for antibiotic resistance from the surrounding environment by direct
uptake.
By undergoing genetic mutation: By undergoing genetic mutations, the bacteria will produce
chemicals which will eliminate the action of antibiotics and in some cases the target will be
modified to escape from antibiotic action.
(2) The genetic code is universal and bacterial cell will try to translate the gene to produce the
protein, but the proteins will not similar to human proteins because
Bacteria are lacking splicing mechanism it cannot splice out the introns from exons and thus it
will try to transcribe and translate the gene with both introns and exons giving different proteins.
In addition to this the proteins produced by bacteria will be different form human cells because,
bacteria used 70S ribosomes and the translation it does is different from the human ribosome and
another thing is codon usage is different in bacteria and we will have different genomic tRNA
pool and the post-translation modification present in human cells is missing in bacteria.
(3) Not all bacteria present in environment can be culturable, what you can see through

stocks, their capital grows very fast as the stocks go up. They also get direct dividend from the
company. They do not have to pay any entry and exit load. They can directly expose to the stock
market.
Cons of investing directly in individual stocks- Investors are directly exposed to risk, pertaining
to particular stock, some stocks are more risky and some are less. Investing directly into
individual stocks does not provide benefit of diversification. Bonds\' prices get fluctuated over
the period of time. It is a risky move.
Pros of Investing indirectly through a mutual fund- Investing into mutual funds gives these
benefits-
Cons of Investing indirectly through a mutual fund- Investing into mutual funds has its own
disadvantage also. It charges some hidden fees and entry and exit loan.

Answer (4): After the slow down in economy and financial markets, new act were being passed
and investors are getting back the confidence in the stock markets. People invested into growth
mutual funds as the market was at lower level. Their mindset was bullish towards the market so

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.
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

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic Imperative
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
