Pouring the product on ice has two effects: Firstly, this reduces the temperature of the mixture. Reducing the temperature of any solution will reduce the solubility of dissolved solutes (such as the product). Secondly, the ice will slightly dissolve at room temperature, increasing the amount of water in your product solution. Methyl m-nitrobenzoate is not soluble in water (which is why you did the reaction in glacial acid instead of dilute water solutions), so this will aid in its precipitation out of solution.

Types of physical situations or occurrencesIt is important to und.pdf
Types of physical situations or occurrences:
It is important to understand the spectrum of threats to information systems so that responsible
administrators can make sure that anticipation measures are widespread.The three types of
physical situations or occurrences that can constitute a threat to information systems within an
enterprise are:
1. Environmental threats:
Natural disasters are the source of a wide range of environmental threats to the information
processing facilities. It is possible to evaluate the risk of different types of natural disasters and
take suitable precautions so that catastrophic loss from natural disaster is prevented.
2. Technical threats:
These threats include electrical power, electromagnetic interference. Electrical power is
important for the operation of information system. All the electrical and electronic devices
require power without interuptions. Power utility problems like low voltage, high voltage and
noise may occur.
Example: Most of the computers are designed to withstand long-drawn-out voltage reductions of
about 20% without shutting down and without operational error. Therefore no damage occurs but
service is interrupted.
3. Human caused threats:
The human-caused threats are unauthorized physical access, theft, destruction of equipment or
data, mis-use of the resources. These threats are difficult to handle compared to environmental
and technical threats. The human caused threats are less predictable than other types of physical
threats.

The term illegal acts, refers to violations of laws or governmental .pdf
The term illegal acts, refers to violations of laws or governmental regulations. Illegal acts by
clients are acts attributable to the entity whose financial statements are under audit or acts by
management or employees acting on behalf of the entity. Illegal acts by clients do not include
personal misconduct by the entity\'s personnel unrelated to their business activities.
When the auditor concludes, based on information obtained and, if necessary, consultation with
legal counsel, that an illegal act has or is likely to have occurred, the auditor should consider the
effect on the financial statements as well as the implications for other aspects of the audit.
The auditor should assure himself that the audit committee is adequately informed as soon as
practicable and prior to the issuance of the auditor\'s report with respect to illegal acts that come
to the auditor’s attention. The auditor need not communicate matters that are clearly
inconsequential and may reach agreement in advance with the audit committee on the nature of
such matters to be communicated. The communication should describe the act, the circumstances
of its occurrence, and the effect on the financial statements. Senior management may wish to
have its remedial actions communicated to the audit committee simultaneously. Possible
remedial actions include disciplinary action against involved personnel, seeking restitution,
adoption of preventive or corrective company policies, and modifications of specific control
activities. If senior management is involved in an illegal act, the auditor should communicate
directly with the audit committee. The communication may be oral or written. If the
communication is oral, the auditor should document it.

Strategic planning has long been used as a tool for transforming and.pdf
Strategic planning has long been used as a tool for transforming and revitalizing corporations,
government agencies and nonprofit organizations. Recently, however, skepticism about planning
has been on the rise. Political and economic uncertainty is the norm and the pace of
technological and social change has accelerated.
No organization exists in a static environment. Social, political and economic trends continually
impact the demand for its offerings and services. Even as advances in technology present new
opportunities, they also generate new expectations. Needs and community demographics are all
subject to change. So too are methods for delivering programs and services. It is thus essential
that a strategic plan reflect the external environment. Programs, services and operations should
be reexamined and reshaped in light of current realities and future projections.

Mandibles refer to the feeding appendages (or jaws) using which food.pdf
Mandibles refer to the feeding appendages (or jaws) using which food is ingested. Depending on
the type of organism and the prey that has to be captured, the structure of the mandible has
evolved over the ages. There are evolutionary and phylogenetic relationships to be considered
with regard to common features in the development of mandibles in insects and vertebrates too.
This is because several insect and crustacean adult mandibles are built in such a way that food is
mainly handled with the lower portion of the jaw.
Insect mandibles have evolved in accordance with the type of food or prey different species need
to catch. Common food sources for insects include algae,other insects, fish, other plants etc.
Insects may pierce the surface of their food and suck out fluids,or graze their food to separate it
from mud and ingest it. They can even bite off some portions of their food before ingestion or
engulf their food as a whole.Some insects chew leaves and other parts of plants. Their mandibles
have evolved accordingly.
Vertebrates have a variety of food sources and do not depend on any single trophic level for their
survival. The muscles that enable mastication of food move the lower jaw of vertebrate
mandibles. In humans, the voice box also moves the mandible. Most vertebrates either engulf
their food or shred it. Many have teeth for feeding, and can be either herbivores or carnivores.
Octopuses are invertebrates having a clever feeding mechanism. They use their long tentacles to
explore crevices for their prey. On capturing their prey, they immediately inject their poisonous
saliva to immobilize it, after which they use their beaks to crush and ingest their prey. They
mostly eat crabs, mollusks, lobsters etc. If the shell of their prey is too tough to break, they use
salivary papilla to drill a pinhole and eat the meat of their prey. Thus, the octopus has evolved a
feeding mechanism suitable to it.

Instruction FormatMachine instruction has an opcode and zero or m.pdf
Instruction Format:
Machine instruction has an opcode and zero or more operands. Architectures are differentiated
from one another by the number of bits allowed per instruction (16, 32, and 64 are the most
common), by the number of operands allowed per instruction, and by the types of instructions
and data each can process. More specifically, instruction sets are differentiated by the following
features:
• Operand storage in the CPU (data can be stored in a stack structure or in registers) • Number of
explicit operands per instruction (zero, one, two, and three being the most common)
• Operand location (instructions can be classified as register-to-register, register-to-memory or
memory-to-memory, which simply refer to the combinations of operands allowed per
instruction)
• Operations (including not only types of operations but also which instructions can access
memory and which cannot) • Type and size of operands (operands can be addresses, numbers, or
even characters)
The following are some common instruction formats:
• OPCODE only (zero addresses)
• OPCODE + 1 Address (usually a memory address)
• OPCODE + 2 Addresses (usually registers, or one register and one memory address)
• OPCODE + 3 Addresses (usually registers, or combinations of registers and memory)
Instruction Length:
The traditional method for describing a computer architecture is to specify the maximum number
of operands, or addresses, contained in each instruction. This has a direct impact on the length of
the instruction itself. Instructions on current architectures can be formatted in two ways: • Fixed
length-Wastes space but is fast and results in better performance when instruction-level
pipelining is used, as we see in Section 5.5. • Variable length-More complex to decode but saves
storage space.
Memory organization affects instruction format. If memory has, for example, 16 or 32-bit words
and is not byte-addressable, it is difficult to access a single character. For this reason, even
machines that have 16-, 32-, or 64-bit words are often byteaddressable, meaning every byte has a
unique address even though words are longer than 1 byte.
COMMON BUS Structure:
The basic computer has eight registers, a memory unit, and a control unit. Paths must be
provided to transfer information from one register to another and between memory and registers.
The number of wires will be excessive if connections are made between the outputs of each
register and the inputs of the other registers. A more efficient scheme for transferring
information in a system with many registers is to use a common bus. It is known that how to
construct a bus PC AR 11 0 11 0 15 0 15 0 7 0 7 0 IR TR INPR AC DR 15 0 15 0 Memory 4096

seven registers and memory are connected to the common bus. The specific output that is
selected for the bus lines at any given time is determined from the binary value of the selection

Natural disasters are the source of a wide range of environmental threats to the information
processing facilities. It is possible to evaluate the risk of different types of natural disasters and
take suitable precautions so that catastrophic loss from natural disaster is prevented.
2. Technical threats:
These threats include electrical power, electromagnetic interference. Electrical power is
important for the operation of information system. All the electrical and electronic devices
require power without interuptions. Power utility problems like low voltage, high voltage and
noise may occur.
Example: Most of the computers are designed to withstand long-drawn-out voltage reductions of
about 20% without shutting down and without operational error. Therefore no damage occurs but
service is interrupted.
3. Human caused threats:
The human-caused threats are unauthorized physical access, theft, destruction of equipment or
data, mis-use of the resources. These threats are difficult to handle compared to environmental
and technical threats. The human caused threats are less predictable than other type.
The term illegal acts, refers to violations of laws or governmental .pdf
The term illegal acts, refers to violations of laws or governmental regulations. Illegal acts by
clients are acts attributable to the entity whose financial statements are under audit or acts by
management or employees acting on behalf of the entity. Illegal acts by clients do not include
personal misconduct by the entity\'s personnel unrelated to their business activities.
When the auditor concludes, based on information obtained and, if necessary, consultation with
legal counsel, that an illegal act has or is likely to have occurred, the auditor should consider the
effect on the financial statements as well as the implications for other aspects of the audit.
The auditor should assure himself that the audit committee is adequately informed as soon as
practicable and prior to the issuance of the auditor\'s report with respect to illegal acts that come
to the auditor’s attention. The auditor need not communicate matters that are clearly
inconsequential and may reach agreement in advance with the audit committee on the nature of
such matters to be communicated. The communication should describe the act, the circumstances
of its occurrence, and the effect on the financial statements. Senior management may wish to
have its remedial actions communicated to the audit committee simultaneously. Possible
remedial actions include disciplinary action against involved personnel, seeking restitution,
adoption of preventive or corrective company policies, and modifications of specific control
activities. If senior management is involved in an illegal act, the auditor should communicate
directly with the audit committee. The communication may be oral or written. If the
communication is oral, the auditor should document it.

Strategic planning has long been used as a tool for transforming and.pdf
Strategic planning has long been used as a tool for transforming and revitalizing corporations,
government agencies and nonprofit organizations. Recently, however, skepticism about planning
has been on the rise. Political and economic uncertainty is the norm and the pace of
technological and social change has accelerated.
No organization exists in a static environment. Social, political and economic trends continually
impact the demand for its offerings and services. Even as advances in technology present new
opportunities, they also generate new expectations. Needs and community demographics are all
subject to change. So too are methods for delivering programs and services. It is thus essential
that a strategic plan reflect the external environment. Programs, services and operations should
be reexamined and reshaped in light of current realities and future projections.

Mandibles refer to the feeding appendages (or jaws) using which food.pdf
Mandibles refer to the feeding appendages (or jaws) using which food is ingested. Depending on
the type of organism and the prey that has to be captured, the structure of the mandible has
evolved over the ages. There are evolutionary and phylogenetic relationships to be considered
with regard to common features in the development of mandibles in insects and vertebrates too.
This is because several insect and crustacean adult mandibles are built in such a way that food is
mainly handled with the lower portion of the jaw.
Insect mandibles have evolved in accordance with the type of food or prey different species need
to catch. Common food sources for insects include algae,other insects, fish, other plants etc.
Insects may pierce the surface of their food and suck out fluids,or graze their food to separate it
from mud and ingest it. They can even bite off some portions of their food before ingestion or
engulf their food as a whole.Some insects chew leaves and other parts of plants. Their mandibles
have evolved accordingly.
Vertebrates have a variety of food sources and do not depend on any single trophic level for their
survival. The muscles that enable mastication of food move the lower jaw of vertebrate
mandibles. In humans, the voice box also moves the mandible. Most vertebrates either engulf
their food or shred it. Many have teeth for feeding, and can be either herbivores or carnivores.
Octopuses are invertebrates having a clever feeding mechanism. They use their long tentacles to
explore crevices for their prey. On capturing their prey, they immediately inject their poisonous
saliva to immobilize it, after which they use their beaks to crush and ingest their prey. They
mostly eat crabs, mollusks, lobsters etc. If the shell of their prey is too tough to break, they use
salivary papilla to drill a pinhole and eat the meat of their prey. Thus, the octopus has evolved a
feeding mechanism suitable to it.

Instruction FormatMachine instruction has an opcode and zero or m.pdf
Instruction Format:
Machine instruction has an opcode and zero or more operands. Architectures are differentiated
from one another by the number of bits allowed per instruction (16, 32, and 64 are the most
common), by the number of operands allowed per instruction, and by the types of instructions
and data each can process. More specifically, instruction sets are differentiated by the following
features:
• Operand storage in the CPU (data can be stored in a stack structure or in registers) • Number of
explicit operands per instruction (zero, one, two, and three being the most common)
• Operand location (instructions can be classified as register-to-register, register-to-memory or
memory-to-memory, which simply refer to the combinations of operands allowed per
instruction)
• Operations (including not only types of operations but also which instructions can access
memory and which cannot) • Type and size of operands (operands can be addresses, numbers, or
even characters)
The following are some common instruction formats:
• OPCODE only (zero addresses)
• OPCODE + 1 Address (usually a memory address)
• OPCODE + 2 Addresses (usually registers, or one register and one memory address)
• OPCODE + 3 Addresses (usually registers, or combinations of registers and memory)
Instruction Length:
The traditional method for describing a computer architecture is to specify the maximum number
of operands, or addresses, contained in each instruction. This has a direct impact on the length of
the instruction itself. Instructions on current architectures can be formatted in two ways: • Fixed
length-Wastes space but is fast and results in better performance when instruction-level
pipelining is used, as we see in Section 5.5. • Variable length-More complex to decode but saves
storage space.
Memory organization affects instruction format. If memory has, for example, 16 or 32-bit words
and is not byte-addressable, it is difficult to access a single character. For this reason, even
machines that have 16-, 32-, or 64-bit words are often byteaddressable, meaning every byte has a
unique address even though words are longer than 1 byte.
COMMON BUS Structure:
The basic computer has eight registers, a memory unit, and a control unit. Paths must be
provided to transfer information from one register to another and between memory and registers.
The number of wires will be excessive if connections are made between the outputs of each
register and the inputs of the other registers. A more efficient scheme for transferring
information in a system with many registers is to use a common bus. It is known that how to
construct a bus PC AR 11 0 11 0 15 0 15 0 7 0 7 0 IR TR INPR AC DR 15 0 15 0 Memory 4096
words 16 bits per word 6 system using multiplexers or three-state buffer gates. The outputs of
seven registers and memory are connected to the common bus. The specific output that is
selected for the bus lines at any given time is determined from the binary value of the selection

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

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.
