Indicate the functions of the agent process in a network operating sys.docx
Indicate the functions of the agent process in a network operating system?
Solution
Answer: In a network operating system, an agent process is involved in the following:
1. In interpreting user commands
2. In deciding whether to allow entry of an host to network services or not.
3. To maintain database of relations among user, remote host and task. For example, information about hosts to which access is allowed for each user, log-in details, nature of allowed tasks etc.
4. In file management including allowing access to files to users as per their authorization at remote hosts.
5. In mapping the textual host name to host address.
6. In maintaing its own directory structure.
7. In maintaining a fixed set of files, common uitlity procedures etc. available to the users of network.
8. May hide file naming and other local conventions from remote user, if required.
9. May provide an environment in which a directory entry can be made for all remote files being accessed by each interested user.

Interpretation 102-4 in the AICPA Code of Professional Conduct calls f.docx
Interpretation 102-4 in the AICPA Code of Professional Conduct calls for differences of opinion between the controller and CFO to be first taken up with:
the CEO.
the board of directors.
the external auditors.
the SEC.
Solution
According to AICPA guideline code 102-4 requires that any financial interpretation should be made in such a manner that it does not represent misstatement of fact. In this connection very often differences in the opinion is observed among two or more members. such difference can be solved in the followng manner:
1. Members will sit together and discuss among themselves on the issue. If it is observed that interpretation properly reflect the fact without any misinterpretation and higher authority is of the same view, then it will be accepted. No changes are required.
2. If members are doubted on these points, then it should be referred to next higher authority. That authority must be within the organization.
In this problem difference in opinion has been observed between controller and chief financial officers. They belong to middle level.There next higher authority is members of board of directors. External auditors or SEC are not belonging to the organization. They are outside authority. Chief financial officer is responsible for financial planning, record keeping andreporting to higher authority. He is directly responsible to Chief executive officer or President of the company.
Thus in this case difference of opinion should be first taken up with CEO. Thereafter if required, it can be taken up with board of Directors.
Answer: Thus correct answer is CEO.

internet domain names are linked to trademark issues- Technology makes.docx
internet domain names are linked to trademark issues. Technology makes it easy to copy and distribute musiceand movies without paying royalties. Business conducted on the internet raise security and privacy issues. What legal concerns are raised by these issues?
Solution
Companies that are solely based on the internet to generate traffic and revenues are faced with an extraordinary amount of breaches. Copying and distributing violates many known laws such as property rights, copy right infringements, as well as many types of torts. Equally important is a breach of the system itself. This breach can and may cause numerous violations putting this company in non-compliance regarding federal codes and state statues. For example, if servers are accessed through an unauthorized fashion, the data stored within may be stolen, compromising property of the company as well as the copyrights to the original owners of that data. The major concerns that currently plague all internet functioning companies are unauthorized access to their networking infrastructure. Such access will greatly affect the company

Internet network management framework as consisting of three major par.docx
Internet network management framework as consisting of three major parts: MIB, SMI, SNMP. To what extent do you believe this constitutes a framework? Are additional parts needed? Why isn’t ASN.1 considered part of the framework?
Solution
In my opinion there major parts of the network management framework can be considered a framework because each serves as a component within the network itself, with this said there are no other parts needed. ASN.1, or abstract syntax notation 1, serves as a base for the SMI, SMI has an ample amount of data types to be thought of as a separate entity.
SMI(structure of management Information) This is a format used to define operations and variables related to objects in the MIB. SMI is more of a language then a structure and it is a language used to define the management information. A cogent language is needed to ensure that data is not vague. SNMP(Simple Network Management Protocol.) SNMP is a protocol used to manage the management communications between devices. This is the short version of SNMP in any case
ASN.1(Abstract Syntax Notation One) Is \". ..a standard and notation that describes rules and structures for representing, encoding, transmitting, and decoding data in telecommunications and computer networking
ASN.1 not considered part of the framework:
ASN.1 for SNMP, the group responsible for SNMP deviated from ASN.1 in various ways which make it impossible for general purpose ASN.1 Tools to fully handle SNMP MIBs. They not only use the withdrawn ASN.1 MACRO notation, but use it in such a way that even ASN.1 Tools which still support the obsolete ASN.1 MACRO notation cannot properly handle the MIB definitions. You need a special tool created specifically for SNMP MIBs to fully parse and handle them properly

international ECO 305 course- how does culture embrace globalization a.docx
international ECO 305 course.
how does culture embrace globalization and the economy ???
Solution
Globalization continues to be a divisive subject among political activists, academics, business leaders, and policymakers. Some look at the rapid economic and political changes taking place around the world and see injustice. Others observe these same changes and see progress. On both sides of the debate, however, much of the discussion takes place among elites. What do average citizens around the world think about the powerful global forces transforming their societies? Survey research suggests that most people embrace the idea of a globalized world, albeit cautiously.
The main economic premises of globalization are generally accepted in regions throughout the world. People tend to believe their countries will benefit from trade, free enterprise, and investment by foreign companies. These views are especially common in many of the world

International business is conducted outside of the home country- Natio.docx
International business is conducted outside of the home country. Nations represent cultural diversity, with unique values, metaphors, stereotypes, idioms and language. How will you deal with people from another country? How will you function effectively when visiting countries with distinctive cultures, such as Mexico, China, Russia, Japan, or Switzerland?
Solution
There is no culture-free theory of management. Managing other people is the responsibility
of people who, like everyone else, have been enculturated and socialized into a cultural
set of values and beliefs that governs their thinking, emotions, and behaviors. Like communication,
management is culture bound. Moreover, managerial perceptions regarding the
factors that lead to organizational success vary across cultures. Unfortunately, many U.S.
managers are ill equipped to handle overseas assignments. In fact, roughly 40% to 50% of all
U.S. managers sent abroad receive no formal cross-cultural training.
As a result, up to 40% of overseas assignments are unsuccessful. Although fostering competent intercultural
managerial skills represents an enormous challenge, the rewards of successful international commerce are extraordinary. Professor Philip Rosenzweig of Harvard University argues that successful cross-cultural
management depends on the abilities of managers to communicate effectively. Rosenzweig
points out that communication is especially important during the initial stages of a business
relationship. Depending on the culture, the process of building trust among business
partners may take days, weeks, or even months. Moreover, Rosenzweig asserts, this process
cannot be accelerated. Rosenzweig recognizes that many American managers prefer

Insight Communications Promotes employees with good technical skills i.docx
Insight Communications Promotes employees with good technical skills into supervisory positions and then teaches them leadership skills.Is this the vst way for the company to get supervisors to lead well?Why and why not
Solution
This is the best way for the company to get supervisors to lead well.
1) This is because the already skilled employees of the comapany are turned into supervisors.
2) They have a know-how of how work is done in the company.
3) They have better rapport(communications ) with other employess.
If instead of this a supervisor is hired as a completly new employee, he will then only have the leadership and management skills. He won\'t have technical skills like an internal employee of the company. This is a major demerit because a person is supervising othe employees who dosen\'t know about the technical work the employees are doing. How can he supervise them?
4) They have a technical know-how.
5) the will cost the company less to convert alredy existing staff to supervisor tha to hire a new one

Infrared radiation is also called IR- Describe how it is different fro (1).docx
Infrared radiation is also called IR. Describe how it is different from visible light. What emits IR? Can animals use it? Explain how emission of IR sometimes “wastes†energy. Give examples showing how IR is used in modern technology.
Solution
Infrared Radiation consists of electromagnetic waves with wavelengths ranging from 700 nm to 1 mm. These radiations cannot be detected by human eye. On the other hand, visible light consists of electromagnetic waves ranging from 380 nm to 700 nm. These radiations can be detected by human eye.
IR are also known as thermal radiations. All objects emit and absorb IR. The hotter the object, the more IR it will emit. Dark surfaces are good emitters of IR.
Some animals have the ability to sense IR, known as IR vision. These animals have specialised IR sensing organs known as pit organs. For example: snake, mosquitoes, bed bugs and vampire bats are kind of animals that uses IR sensing to track their prey or any potential danger approaching them.
Infrared radiations are associated with thermal energy. In most of the devices, emission of thermal energy is waste of energy. For example: a light bulb generates heat along with light energy on passage of electricity. Now this heat energy is not a useful energy and gets wasted in the environment.
Use of IR in Modern technology:
1. It is used in heat sensitive thermal imaging cameras. They are used to study heat patterns of humans and animals. They are also used as night cameras.
2. IR is used in gas monitoring and analyzing systems. These systems are used for testing air samples to see what gases are contained in that sample.
3. It is used in thermal imaging and thermal motion detection. Thermal imaging is used by firefighters to see where a burning building is too hot to safely enter. Thermal imaging is used for space imaging and to know the temperature of distant stars.

Infrared radiation is also called IR. Describe how it is different from visible light. What emits IR? Can animals use it? Explain how emission of IR sometimes “wastes†energy. Give examples showing how IR is used in modern technology.
Solution
basic differences are- The electromagnetic spectrum comprises all wavelengths of light from the very short (gamma rays) to the very long (radio waves). Both visible and IR light are near the middle of the spectrum
The wavelength of an electromagnetic wave is the distance between peaks (or troughs) of the wave. IR radiation has longer wavelengths than visible light.
The frequency of a wave is a measure of how many times the wave oscillates between its minimum and maximum amplitude in one second. The frequencies of IR waves are less than the frequencies of visible ligh
All objects on Earth emit ir r adiation
Blood-sucking insects, such as bedbugs and mosquitoes, rely on their infrared vision to feed themselves. They can \"see\" body heat and use the heat signature of the carbon dioxide (CO2) gas that humans and other animals naturally exhale to locate their prey.

Name the four classes of coding methods. Identify whether each compression method is lossy or lossless: Morse Code_____Run Length Encoding_____JPEG_____Say the relative frequencies of four symbols in an alphabet are 1/2,1/4,1/8 and 1/8. What is the entropy (numerical value) of the alphabet? Suppose we want to compress two sound recordings, A and B that are in.WAV format and equally long. If the entropy of A is twice that of B, which recording has a greater amount of randomness? Which recording should we expect to be shorter in compressed form?
Solution
As already short answer provided for other questions except Q10, I am answering it.
10)
Relative frequencies of four symbols in an alphabet are, ½, ¼, 1/8, 1/8,
So P(1) = ½
P(2) = ¼
P(3) = 1/8
P(4) = 1/8
Entropy of the alphabet = H(P) = - [ P(1) logP(1) + P(2) logP(2) + P(3) logP(3)+ P(4) logP(4)]
= - [1/2log(1/2) + ¼ log(1/4) +1/8 log(1/8) +1/8 log(1/8)]
= - [(-0.150514998) + (-0.150514998) + (-0.112886248) + (-0.112886248)]

Solution
Yes your answer is right.
i) Half reaction represents either the anodic half or cathodic half reaction.Here the question is asked about half reaction in iron electrode. In the given cell, Fe is acting as cathode. Hence it should undergo reduction. your equation representing reduction of Fe 2+ to Fe is right.
ii) Ionic equation including state symbols is asked. Ionic equation is nothing but the overall cell reaction represented in ionic form. Simply it is combination of cathode half reaction and anode half reaction. In the given cell, Magnesium is the anode. It undergoes oxidation. i.e. Mg(s) to Mg 2+ by loss of two electrons. We have already seen the cathode half reaction of reduction of Fe. Combining these two half reactions we get the overall ionic reaction
Mg (s) + Fe 2+ (aq) --------> Mg 2+ (aq) + Fe (s)

Beryllium oxide (BeO) prefers the Wurtzite structure type (typical of ZnS) while LiF prefers the rock-salt structure type (typical of NaCI). Why does this happen? Use the following terms/words in your explanation a) ionic radii b) chemical bonding
Solution
Beryllium oxide prefers wurtzite structure type whereas LiF prefers rocksalt type structure.
If we look all these elements, namely, Be, O, Li, and F falls in the second period of periodic structure. Atomic radius decreases from left to right in the periodic table. This is because of addition of an electron in the same shell of the atom which compresses the atom due to more attraction towarrds the nucleus. The electronegativity of elements increases from left to right since it is inverse property of atomic radii. Atomic radius of Be 2+ is less than Li + whereas atomic size of O 2- is more than F - . Moreover, LiF is ionic in natute due to coulombic interaction of highly electropositive atom (Li) and highly electronegative atom (F). On the other hand, BeO is having covalent character along with ionic character in their chemical bond. Thus, BeO prefers wurtzite structure type whereas LiF prefers rocksalt type structure.

Indonesian lenders are the most profitable business in the world- The.docx
Indonesian lenders are the most profitable business in the world. The average return on equity is 23% more than double the 9% in the US. The main issue is he limited supply of official lenders, prompting an average interest of 16-20% for short term loans (BusinessWeek, 2/24/13). Some consider this a form of usury. Usury is an excessive or exorbitant interest charge. In order to prevent usury, and politicians trying to save the \"little guy\" from the clutches of the greedy \"money lenders\", Indonesian government steps in and sets the upper limits on what can be charged for loan to 18%. Today, market forces pushed the interest rate at 20%, only $10 million in loans were made but 32 million were demanded. Graph the loan market and show the impact of setting upper limits on interest rate. Please explain.
Solution
it happend because of the government intervention, according to this expanation it is obeserving that the Indonesian business entities are in need of funds and even there are some people, having with surplus funds.
becuse of the ceiling in interest the flow of funds declined into the market, if the situation runs for a long while it leads to create many problems.
the supply is lesser than demand of funds, so automatically the lenders seek high interest rates other wise they wont ready to lend their money at lesser interest rates.

Indicate whether the following characteristics are primarily associate.docx
Indicate whether the following characteristics are primarily associated with public sector or private sector projects.
Profits
Taxes
Disbenefits
Infinite life
Corporate bonds
Solution
a) sector projects are always indicated to public sector as for a public sector a particlar region is divided into different area so we always have sector projects for public sector
b) profits are always for private sector becuase a public sector is always a government sector
Government never expects profits but in a public sector they are more intrested in profits
c) taxes are always associated with private sector as public sector is tax free as it is government firm
d) disbenifits are always for a public sector due to one fact public sector never thinks about benifits it thinks about welfare
e) infinite line is nothing but dead line but it will be associated with both public and private sector but in private sector it is more associated because they always have dead lines for any projects but in public sector they never care about infinite line
f) corporate bonds are associated with both the sectors as they have inter linking connections with all firms

Interpretation 102-4 in the AICPA Code of Professional Conduct calls f.docx
Interpretation 102-4 in the AICPA Code of Professional Conduct calls for differences of opinion between the controller and CFO to be first taken up with:
the CEO.
the board of directors.
the external auditors.
the SEC.
Solution
According to AICPA guideline code 102-4 requires that any financial interpretation should be made in such a manner that it does not represent misstatement of fact. In this connection very often differences in the opinion is observed among two or more members. such difference can be solved in the followng manner:
1. Members will sit together and discuss among themselves on the issue. If it is observed that interpretation properly reflect the fact without any misinterpretation and higher authority is of the same view, then it will be accepted. No changes are required.
2. If members are doubted on these points, then it should be referred to next higher authority. That authority must be within the organization.
In this problem difference in opinion has been observed between controller and chief financial officers. They belong to middle level.There next higher authority is members of board of directors. External auditors or SEC are not belonging to the organization. They are outside authority. Chief financial officer is responsible for financial planning, record keeping andreporting to higher authority. He is directly responsible to Chief executive officer or President of the company.
Thus in this case difference of opinion should be first taken up with CEO. Thereafter if required, it can be taken up with board of Directors.
Answer: Thus correct answer is CEO.

internet domain names are linked to trademark issues- Technology makes.docx
internet domain names are linked to trademark issues. Technology makes it easy to copy and distribute musiceand movies without paying royalties. Business conducted on the internet raise security and privacy issues. What legal concerns are raised by these issues?
Solution
Companies that are solely based on the internet to generate traffic and revenues are faced with an extraordinary amount of breaches. Copying and distributing violates many known laws such as property rights, copy right infringements, as well as many types of torts. Equally important is a breach of the system itself. This breach can and may cause numerous violations putting this company in non-compliance regarding federal codes and state statues. For example, if servers are accessed through an unauthorized fashion, the data stored within may be stolen, compromising property of the company as well as the copyrights to the original owners of that data. The major concerns that currently plague all internet functioning companies are unauthorized access to their networking infrastructure. Such access will greatly affect the company

Internet network management framework as consisting of three major par.docx
Internet network management framework as consisting of three major parts: MIB, SMI, SNMP. To what extent do you believe this constitutes a framework? Are additional parts needed? Why isn’t ASN.1 considered part of the framework?
Solution
In my opinion there major parts of the network management framework can be considered a framework because each serves as a component within the network itself, with this said there are no other parts needed. ASN.1, or abstract syntax notation 1, serves as a base for the SMI, SMI has an ample amount of data types to be thought of as a separate entity.
SMI(structure of management Information) This is a format used to define operations and variables related to objects in the MIB. SMI is more of a language then a structure and it is a language used to define the management information. A cogent language is needed to ensure that data is not vague. SNMP(Simple Network Management Protocol.) SNMP is a protocol used to manage the management communications between devices. This is the short version of SNMP in any case
ASN.1(Abstract Syntax Notation One) Is \". ..a standard and notation that describes rules and structures for representing, encoding, transmitting, and decoding data in telecommunications and computer networking
ASN.1 not considered part of the framework:
ASN.1 for SNMP, the group responsible for SNMP deviated from ASN.1 in various ways which make it impossible for general purpose ASN.1 Tools to fully handle SNMP MIBs. They not only use the withdrawn ASN.1 MACRO notation, but use it in such a way that even ASN.1 Tools which still support the obsolete ASN.1 MACRO notation cannot properly handle the MIB definitions. You need a special tool created specifically for SNMP MIBs to fully parse and handle them properly

international ECO 305 course- how does culture embrace globalization a.docx
international ECO 305 course.
how does culture embrace globalization and the economy ???
Solution
Globalization continues to be a divisive subject among political activists, academics, business leaders, and policymakers. Some look at the rapid economic and political changes taking place around the world and see injustice. Others observe these same changes and see progress. On both sides of the debate, however, much of the discussion takes place among elites. What do average citizens around the world think about the powerful global forces transforming their societies? Survey research suggests that most people embrace the idea of a globalized world, albeit cautiously.
The main economic premises of globalization are generally accepted in regions throughout the world. People tend to believe their countries will benefit from trade, free enterprise, and investment by foreign companies. These views are especially common in many of the world

International business is conducted outside of the home country- Natio.docx
International business is conducted outside of the home country. Nations represent cultural diversity, with unique values, metaphors, stereotypes, idioms and language. How will you deal with people from another country? How will you function effectively when visiting countries with distinctive cultures, such as Mexico, China, Russia, Japan, or Switzerland?
Solution
There is no culture-free theory of management. Managing other people is the responsibility
of people who, like everyone else, have been enculturated and socialized into a cultural
set of values and beliefs that governs their thinking, emotions, and behaviors. Like communication,
management is culture bound. Moreover, managerial perceptions regarding the
factors that lead to organizational success vary across cultures. Unfortunately, many U.S.
managers are ill equipped to handle overseas assignments. In fact, roughly 40% to 50% of all
U.S. managers sent abroad receive no formal cross-cultural training.
As a result, up to 40% of overseas assignments are unsuccessful. Although fostering competent intercultural
managerial skills represents an enormous challenge, the rewards of successful international commerce are extraordinary. Professor Philip Rosenzweig of Harvard University argues that successful cross-cultural
management depends on the abilities of managers to communicate effectively. Rosenzweig
points out that communication is especially important during the initial stages of a business
relationship. Depending on the culture, the process of building trust among business
partners may take days, weeks, or even months. Moreover, Rosenzweig asserts, this process
cannot be accelerated. Rosenzweig recognizes that many American managers prefer

Insight Communications Promotes employees with good technical skills i.docx
Insight Communications Promotes employees with good technical skills into supervisory positions and then teaches them leadership skills.Is this the vst way for the company to get supervisors to lead well?Why and why not
Solution
This is the best way for the company to get supervisors to lead well.
1) This is because the already skilled employees of the comapany are turned into supervisors.
2) They have a know-how of how work is done in the company.
3) They have better rapport(communications ) with other employess.
If instead of this a supervisor is hired as a completly new employee, he will then only have the leadership and management skills. He won\'t have technical skills like an internal employee of the company. This is a major demerit because a person is supervising othe employees who dosen\'t know about the technical work the employees are doing. How can he supervise them?
4) They have a technical know-how.
5) the will cost the company less to convert alredy existing staff to supervisor tha to hire a new one

Infrared radiation is also called IR- Describe how it is different fro (1).docx
Infrared radiation is also called IR. Describe how it is different from visible light. What emits IR? Can animals use it? Explain how emission of IR sometimes “wastes†energy. Give examples showing how IR is used in modern technology.
Solution
Infrared Radiation consists of electromagnetic waves with wavelengths ranging from 700 nm to 1 mm. These radiations cannot be detected by human eye. On the other hand, visible light consists of electromagnetic waves ranging from 380 nm to 700 nm. These radiations can be detected by human eye.
IR are also known as thermal radiations. All objects emit and absorb IR. The hotter the object, the more IR it will emit. Dark surfaces are good emitters of IR.
Some animals have the ability to sense IR, known as IR vision. These animals have specialised IR sensing organs known as pit organs. For example: snake, mosquitoes, bed bugs and vampire bats are kind of animals that uses IR sensing to track their prey or any potential danger approaching them.
Infrared radiations are associated with thermal energy. In most of the devices, emission of thermal energy is waste of energy. For example: a light bulb generates heat along with light energy on passage of electricity. Now this heat energy is not a useful energy and gets wasted in the environment.
Use of IR in Modern technology:
1. It is used in heat sensitive thermal imaging cameras. They are used to study heat patterns of humans and animals. They are also used as night cameras.
2. IR is used in gas monitoring and analyzing systems. These systems are used for testing air samples to see what gases are contained in that sample.
3. It is used in thermal imaging and thermal motion detection. Thermal imaging is used by firefighters to see where a burning building is too hot to safely enter. Thermal imaging is used for space imaging and to know the temperature of distant stars.

Solution
basic differences are- The electromagnetic spectrum comprises all wavelengths of light from the very short (gamma rays) to the very long (radio waves). Both visible and IR light are near the middle of the spectrum
The wavelength of an electromagnetic wave is the distance between peaks (or troughs) of the wave. IR radiation has longer wavelengths than visible light.
The frequency of a wave is a measure of how many times the wave oscillates between its minimum and maximum amplitude in one second. The frequencies of IR waves are less than the frequencies of visible ligh
All objects on Earth emit ir r adiation

What is the entropy (numerical value) of the alphabet? Suppose we want to compress two sound recordings, A and B that are in.WAV format and equally long. If the entropy of A is twice that of B, which recording has a greater amount of randomness? Which recording should we expect to be shorter in compressed form?
Solution
As already short answer provided for other questions except Q10, I am answering it.
10)
Relative frequencies of four symbols in an alphabet are, ½, ¼, 1/8, 1/8,
So P(1) = ½
P(2) = ¼
P(3) = 1/8
P(4) = 1/8
Entropy of the alphabet = H(P) = - [ P(1) logP(1) + P(2) logP(2) + P(3) logP(3)+ P(4) logP(4)]
= - [1/2log(1/2) + ¼ log(1/4) +1/8 log(1/8) +1/8 log(1/8)]
= - [(-0.150514998) + (-0.150514998) + (-0.112886248) + (-0.112886248)]

Solution
Yes your answer is right.
i) Half reaction represents either the anodic half or cathodic half reaction.Here the question is asked about half reaction in iron electrode. In the given cell, Fe is acting as cathode. Hence it should undergo reduction. your equation representing reduction of Fe 2+ to Fe is right.
ii) Ionic equation including state symbols is asked. Ionic equation is nothing but the overall cell reaction represented in ionic form. Simply it is combination of cathode half reaction and anode half reaction. In the given cell, Magnesium is the anode. It undergoes oxidation. i.e. Mg(s) to Mg 2+ by loss of two electrons. We have already seen the cathode half reaction of reduction of Fe. Combining these two half reactions we get the overall ionic reaction

Inorganic Chemistry - Wurtzite vs- Rock-Salt Structures Beryllium oxid.docx
Inorganic Chemistry - Wurtzite vs. Rock-Salt Structures
Beryllium oxide (BeO) prefers the Wurtzite structure type (typical of ZnS) while LiF prefers the rock-salt structure type (typical of NaCI). Why does this happen? Use the following terms/words in your explanation a) ionic radii b) chemical bonding
Solution
Beryllium oxide prefers wurtzite structure type whereas LiF prefers rocksalt type structure.
If we look all these elements, namely, Be, O, Li, and F falls in the second period of periodic structure. Atomic radius decreases from left to right in the periodic table. This is because of addition of an electron in the same shell of the atom which compresses the atom due to more attraction towarrds the nucleus. The electronegativity of elements increases from left to right since it is inverse property of atomic radii. Atomic radius of Be 2+ is less than Li + whereas atomic size of O 2- is more than F - . Moreover, LiF is ionic in natute due to coulombic interaction of highly electropositive atom (Li) and highly electronegative atom (F). On the other hand, BeO is having covalent character along with ionic character in their chemical bond. Thus, BeO prefers wurtzite structure type whereas LiF prefers rocksalt type structure.

Indonesian lenders are the most profitable business in the world. The average return on equity is 23% more than double the 9% in the US. The main issue is he limited supply of official lenders, prompting an average interest of 16-20% for short term loans (BusinessWeek, 2/24/13). Some consider this a form of usury. Usury is an excessive or exorbitant interest charge. In order to prevent usury, and politicians trying to save the \"little guy\" from the clutches of the greedy \"money lenders\", Indonesian government steps in and sets the upper limits on what can be charged for loan to 18%. Today, market forces pushed the interest rate at 20%, only $10 million in loans were made but 32 million were demanded. Graph the loan market and show the impact of setting upper limits on interest rate. Please explain.
Solution
it happend because of the government intervention, according to this expanation it is obeserving that the Indonesian business entities are in need of funds and even there are some people, having with surplus funds.
becuse of the ceiling in interest the flow of funds declined into the market, if the situation runs for a long while it leads to create many problems.
the supply is lesser than demand of funds, so automatically the lenders seek high interest rates other wise they wont ready to lend their money at lesser interest rates.

Indicate whether the following characteristics are primarily associate.docx
Indicate whether the following characteristics are primarily associated with public sector or private sector projects.
Profits
Taxes
Disbenefits
Infinite life
Corporate bonds
Solution
a) sector projects are always indicated to public sector as for a public sector a particlar region is divided into different area so we always have sector projects for public sector
b) profits are always for private sector becuase a public sector is always a government sector
Government never expects profits but in a public sector they are more intrested in profits
c) taxes are always associated with private sector as public sector is tax free as it is government firm
d) disbenifits are always for a public sector due to one fact public sector never thinks about benifits it thinks about welfare
e) infinite line is nothing but dead line but it will be associated with both public and private sector but in private sector it is more associated because they always have dead lines for any projects but in public sector they never care about infinite line
f) corporate bonds are associated with both the sectors as they have inter linking connections with all firms

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

In which part of the atmosphere is the ozone layer found- (B) Stratosp.docx
- 1. In which part of the atmosphere is the ozone layer found? (B) Stratosphere (C) MesosphereDThermosphere Burning coal often produces a toxic gas that could lead to the formation of acid rains. Identify the gas (B) N (C) CO (D) SO In the liquid state, molecules of which compound interact with one another by hydrogen bonding? (A) CH,CH (B) CH,F (C) CH OH (D) All of them Molecules of this substance attract each other by London dispersion force only (B) N O (C) SO (D) SiO2 Solution 1. The ozone layer is found in the (B) Stratosphere. 2. Burning coal produce (D) SO2. 3. In liquid form (C) Methanol interact with one another through hydrogen bonding. 4. (D) SiO2 London dispersion force exists. --------------------------------------------------------------------------------- 1. The Ozone Layer absorbs UV radiation from the Sun, at stratosphere air is very thin, and the ozone layer are at a height 20-60 km from earth surface. 2. Burning coal produce SO2 gases, which combine with oxygen and form SO3 gas which reacts with water in the atmosphere and form H2SO4. 3. Methanol form H-bonds with neighboring CH3-OH molecules tough CH3-O-H….OH-CH3 type hydrogen bonds. Other compounds CH3CH3 and CH3F don’t have any strong H-bond donor atom. 4 Among the series, CO2, N2O, SO2, SiO2 except for SiO2 all are polar molecules, they interact through dipole-dipole interaction. SiO2 is a non-polar polymer, London dispersion force exists.
