When the body needs to conserve water, the kidneys excrete a hyperton.pdf
When the body needs to conserve water, the kidneys excrete a hypertonic urine. What do the
terms Isotonic and hypertonic mean? Since the fluid that is to become urine begins as plasma (an
isotonic solution), what must happen change it to a hypertonic urine? Explain.
Solution
Answer
An isotonic solution refers to two solutions that have same concentration of solutes, where as a
hypertonic solution is the one where the concentration of solutes is greater than the other
solution.
So, the fluid that is to become urine begins as plasma is isotonic
When this fluid passes through the different parts of Nephron (Bowmans capsule, Proximal
convoluted tubule, distal convoluted tubule) it looses only water but not solutes
Hence, the urine becomes more and more concentrated.
This is known as hypertonic urine.

What two things are added to NADP+ to convert it into NADPH H+ and .pdf
What two things are added to NADP+ to convert it into NADPH? H+ and electrons electrons
and ATP H+ and ATP H+ and CO2 electrons and CO2
Solution
H+ and electrons.
NADP (Nicotinamide Adenine Dinucleotide Phosphate) exists in two forms: NADP+is the
oxidized form andNADPHis the reduced form.
NADP+ takes 2 electrons from Ferredoxin at the end of the electron transport chain to generate
NADP. An H+ ion in the stroma binds through the extra electron, generating NADPH. All of this
is facilitated by Ferredoxin-NADP+reductase..

What impact did the Industrial Revolution have on American society b.pdf
What impact did the Industrial Revolution have on American society between 1870 and 1940?
Was it largely beneficial or not? Or was its impact more mixed? In your answer, be sure to
consider the economic, social, and environmental consequences of industrialization.
Solution
Before the industrial revolution. America was an agrarian society. Almost everyone farmed.
After the Industrial revolution, more people lived in cities and worked in factories than ever
before. Cities grew larger and more crowded, which prompted the rise of better transportation,
land speculation, real estate boom. The standard of living rose.
The Industrial Revolution was a big turning point in American history. It changed the whole
composition of families who had too move to the city so that they could work. It was one of the
main contributions to the growth of cities. Frankly speaking early Industries weren\'t too fond of
their workers either so this also led to the rise of labor unions that \'til this day still exist (your
teacher is probably part of one). Big picture is that Industrial Revolution eventually led to the
transportation revolution and also reduced the cost of production leading to mass production and
cheaper items for Americans
Considering the impact of the Industrial Revolution on American society is both complicated as
well as interesting for the reason there are countless social issues to examine when analyzing the
impact that this milestone era had upon the citizens of America. Primarily, though, the
consequence of the Industrial Revolution is that, by means of making more effective the
manufactured goods\' production, it aided to trim down the commodities costs for consumers,
therefore allowing a number of items once measured luxuries to turn out to be within reach for
vast sectors of American population. Together with the price structures reducing for a number of
items, from crop tools to furniture to textiles, Americans took in a high standard of living.
The increase in living standard of Americans translated to the nation\'s general public enjoying
more amenities and conveniences for a comparatively economical cost. Moreover, the economy
of the nation enjoyed spurts of outstanding growth all through this era on account of exports and
consumer spending. One more advantage of the Industrial Revolution in this regard is that
several jobs were created to fulfill the requirements of machinery operation and assembly lines..

What are the major inputs to the MRP systemSolutionMaterial r.pdf
What are the major inputs to the MRP system?
Solution
Material requirements planning (MRP) is a computer-based inventory management system
designed to assist production managers in scheduling and placing orders for items of dependent
demand. Dependent demand items are components of finished goods—such as raw materials,
component parts, and subassemblies—for which the amount of inventory needed depends on the
level of production of the final product..
Type I alveolar cells(a) allow rapid diffusion of gases through t.pdf
Type I alveolar cells:
(a) allow rapid diffusion of gases through their membranes.
(b) secrete a chemical known as surfactant.
(c) are phagocytic.
(d) A, B, and C.
(e) None of the above.
Solution
(a) allow rapid diffusion of gases through their membranes.
Type I alveolar cells are squamous which gives more surface area to each cell and cover
approximately 90–95% of the alveolar surface. Type I cells are involved in the process of gas
exchange between the alveoli and blood. These cells are extremely thin.These cells need to be so
thin to be readily permeable for enabling an easy gas exchange between the alveoli and the
blood..
The memory cycle times have been much longer than processor cycle ti.pdf
The memory cycle times have been much longer than processor cycle times; this speed gap
between the memory and the processor means that the processor must wait for memory to
respond to an access request. The obvious method of increasing the speed of the memory system
is by using a higher speed memory technology. Once the technology is selected, the access
speeds can be increased further by different address decoding and access techniques. Described
in details at least 3 of them
Solution
The different techniques are:
1. Banking: The main memory is built out of several physical-memory modules. Each and every
module is a memory bank of a certain capacity and consists of a MAR and a MBR. In
semiconductor memories, each module corresponds to either a memory IC or a memory board
consisting of several memory ICs. The consecutive addresses lie in the same bank. If each bank
contains 2n = N words and if there are 2m = M banks in the memor y, then the system MAR
would contain n + m bits.
2. Multiport Memories: Multiple memories are available in which each port corresponds to an
MAR and an MBR . Independent access to the memory can be made from each port. The
memory system resolves the conflicts between the ports on a priority basis. Multiport memories
are useful in an environment where more than one device accesses the memory. Examples of
such systems are a single-processor system with a direct-memory access (DMA), I =O controller,
and a multiprocessor system with more than one CPU.
3.Instruction Buffer: The instruction buffer, Providing a first-in, first-out (FIFO) buffer between
the CPU and the primary memory enhances the instruction fetch speed . Instructions from the
primary memory are fed into the buffer at one end and the CPU fetches the instructions from the
other end. As long as the instruction execution is sequential, the two operations of filling the
buffer and fetching from the buffer into CPU can go on simultaneously. But when a jump
(conditional or unconditional) instruction is executed, the next instruction to be executed may or
may not be in the buffer. The buffer management requires hardware component to manage the
queue and mechanisms to identify the address range in the buffer and to freeze and unfreeze the
buffer. INTEL 8086 processor uses a 6 -byte long instruction buffer organized as a queue. CDC
6600 uses an instruction buffer that can store eight 60-bit words, that is, 16–32 instructions, since
the instructions are either 15- or 30-bits long..
Suppose you land on a previously unexplored South Pacific island. Yo.pdf
Suppose you land on a previously unexplored South Pacific island. You find three novel bird
species. Two are small, one of these specializing in seed eating, the other in eating grubs and
insects. Both show highly camouflaged coloration. The third bird species is substantially larger
and is a dedicated predator; this third species specializes in preying on small rodents and the
other two bird species. Its coat is brightly colored. Which of the following is the statement about
the evolutionary relationships of these three species that we can make with the most confidence?
[\"Relationship\" and \"relatedness\" here refers to phylogenetic history. Closely related species
descended from the same ancestral species recently. In contrast, more distantly related species
last had a common ancestor further in the past
A) We cannot draw any conclusions about phylogenetic relationships of these species based on
the data given; we would need additional data, like insights into selective history or fossil
evidence.
b.We cannot draw any conclusions about phylogenetic relationships of these species based on the
data given; bird evolution works differently than mammalian evolution.
Suppose you are a member of an island population of people that contains about 1000
individuals and that has remained stable in size (with no new immigration) for many dozens of
generations. Now suppose you could time travel into the future 300 years (ten generations).
Which of the answers below is the best description, first, of the fraction of the future population
of the island that are expected to be your descendants (on average) and, second, how closely
related you are to those future descendants in comparison to your relatedness to the other
contemporary residents of the island? [Note that \"relatedness\" here refers to the specific
parameter \"r\" as discussed it in TOPIC 5, that is, \"genetic relatedness\" from the gene\'s
perspective.]
Most or all of the future residents of the island would be my descendants and I would be more
than twice as closely related to them than I am to any randomly chosen member of the
contemporary population.
Approximately 10% of the future population of the island would be my descendants and I would
be roughly 10 times more closely related to them as I am to any randomly chosen member of the
contemporary population.
Most or all of the future residents of the island would be my descendants and I would be no more
closely related to them than I am to any randomly chosen member of the contemporary
population.
d) Approximately 20% of the future population of the island would be my descendants and I
would be roughly 5 times more closely related to them as I am to any randomly chosen member
of the contemporary population.
A) We cannot draw any conclusions about phylogenetic relationships of these species based on
the data given; we would need additional data, like insights into selective history or fossil
evidence.
b.We cannot draw any conclusions abou.
State two factors that have contributed to the development of emergi.pdf
State two factors that have contributed to the development of emerging infectious diseases.
For either Rabies or Anthrax, provide the following information:
1.Causative agent (e.g., viral, bacterial, parasitic)
2.Symptoms (at least two)
3.Geographic distribution
4.Host factors
5.Responsible vector
6.Potential human hazards
7.A method of control
Solution
1. The causative agent of rabies is virus called Rabies virus (RV) or Lyssavirus which is a
negative stranded ribonucleic acid virus belonging to rhabdovirus family.
The causative agent of Anthrax is a bacillus bacterium called Bacillus anthracis which is a large
Gram positive rod shaped aerobic belonging to Rhabdoviridae family.
2. The symptoms of Rabies are initially similar to flu which includes fever, muscle weakness and
tingling. Other symptoms include insomnia, anxiety, excess salivation, hydrophobia, problems in
swallowing etc.
The symptoms of Anthrax are different depending upon the route of infection. The symptoms of
cutaneous anthrax are raised itchy bump like insect bite alongwith swelling in the lymph glands
and sore. The symptoms of gastrointestinal anthrax include nausea,vomiting, headache. loss of
appetite, severe bloody diarrhoea, swollen neck etc. The symptoms of pulmonary anthrax include
flu like symptoms with shortness of breath, coughing up blood, nausea etc.The symptoms of
injection anthrax include redness and swelling of the area of infection, shock,meningitis,
multiple organ failure etc.
3. Rabies is present in mammals in most parts of the world. Per year Most of the estimated 55
000 human rabies deaths occur in Africa and Asia.
Sporadic cases of Anthrax occur in animals worldwide. However there are occasional outbreaks
in Africa, central and southern Asia.
4. Like many rhabdoviruses, Rabies virus has an extremely wide host range. Many mammalian
species in the wild has been found infecting , while in the laboratory it has been found that birds
can be infected, as well as cell cultures from mammals, birds, reptiles and insects.
Anthrax is spread from infectious animal products by contact with the spores of the bacteria.
Contact is by breathing, eating, or through an area of broken skin. It does not typically spread
directly between people.
5. There are three vectors for rabies:
c. Tissue transplants (such as corneas) from infected humans.
In its infectious form, anthrax is a spore that usually populates the soil but which, in rare cases,
can become airborne and inhaled. With cutaneous anthrax, the bacteria infects the host through
direct penetration of the host skin.
It depends on the death of its host for propagation which is different from many pathogenic
organisms. Once the host is dead, its body starts decaying and the bacteria in the bloodstream are
exposed to oxygen. These bacteria turn into spores which populate the surrounding soil.. The
spores can be eaten up by herbivores or from cutaneous infection.
Anthrax does not appear to be transmissable from person to per.

Research and prepare a presentation to demonstrate a scenario in whi.pdf
Research and prepare a presentation to demonstrate a scenario in which object-based storage is a
better choice over SAN and NAS.
Solution
Since there is no privelege to provide you an attachement of slide deck, we are providing you the
scenario based idea in which object-based storage is a better choice over SAN and NAS.So here
it is:
Even though several storage type exists, a single type of storage solution doesnot fit everybody\'s
needs.
Object storage is of major importance (current pretty much good option) in large storage
deployments, especially in the cloud based scenario.
Representing the data may be different from storing data. Also, scaling out storage has strained
both the NAS (Network Attached Storage) and SAN(Storage Attached Networks) storage
models.
SAN is a high speed network that makes connections between storage devices and servers.The
server can only access data on the devices, which are directly attached to it.If server crashes or
anything happens to the server, access to data will fail. There is a limit in the number of storage
devices the server can access. SAN is primarily used for higher performance block level storage
of data.
Network Attached Storage shares files over the network. Not storage devices over the network.
Any server that shares its own storage with others on the network and acts as a file server is an
example for simplest form NAS. NAS devices are computers within themselves and shares their
storage space with others. If you share a folder with access control using SAMBA, its NAS.
NAS is primarily used for long distance small IO operations.
Object storage which is famous in Cloud nowadays is like NAS but not exactly. Here each data
block is replicated on serveral storage disks for integrity. Each of these storage models uses their
own protocols. Object storage - Swift in OpenStack private cloud is good example. Ceph is also
converged storage solution which is gaining momentum at highest rate nowadays.And Object
storage is developer\'s choice where in data can be accessed anytime, easily & anywhere with an
internet connection using REST APIs..

Looking at the symptoms of SARS is not really enough to diagnose it..pdf
Looking at the symptoms of SARS is not really enough to diagnose it. The initial symptoms are
similar to that of the flu. So, what other factors would have to be used to distinguish it from the
flu and other respiratory illnesses? What criteria is used to diagnose SARS? What kinds of tests
are needed? Explain.
Solution
Answer:
SARS (Severe Acute Respiratory Syndrome) is a serious respiratory disease that is contagious.
The SARS vrus is basically coronavirus and belongs to the same family of common cold virus.
The symptoms of SARS are similar to those of flu and the patient go on to develop pneumonia in
most cases. SARS is very rare and the only way to diagnose SARS is whether or not the patient
got exposed to the SARS virus.
Criteria to diagnose SARS quickly:
1. Direct isolation and identification of the SARS virus
2. PCR of the virus with specific primers (Detection of SARS-CoV in samples such as blood)
3. Antibody tests for the virus (ELISA and Immunofluorescence assay for the SARS virus)
Other laboratory tests include:
1. Blood clotting test
2. Blood chemistry test
3. Chest X-ray
4. Arterial blood tests.

How does friction heating effect pressure dropSolutionHeat tr.pdf
How does friction heating effect pressure drop?
Solution
Heat transfer is not the consequence (or effect) of pressure drop. In the absence of a temperature
gradient, it is possible to have pressure drop in a flow without heat transfer. Similarly, in
unconfined convection over an external surface (imagine flow over a hot flat plate or for more
simplicity, an aircraft flying at altitude), it is possible to have heat transfer without a pressure
drop. (The pressures in front of the aircraft as well as behind the aircraft are the same!)
Both pressure drop and heat transfer are consequences of a velocity gradient. For real fluids, a
velocity gradient produces a shear force which is overcome by a sacrifice of fluid pressure (as in
pipe flow). On the other hand, a velocity gradient gives rise to convective diffusion.
In general, heat transfer is the desired effect while pressure drop is how we pay for that
effect.This relationship is simply and beautifully brought out by the simplest of all analogies, the
Reynolds Analogy. The friction factor fand the Conburn \'j\' factor are related as f/j 2. In other
words, f can never be less than 2 x j.h and f which are convection and friction factor parameters ..

Answer:
NRC :National Resource Council
National Resource Council is first organised in 1916 by National academy of sciences. NRC
deals with criminal cases using DNA testing.
In 1992, NRC-I report was issue about DNA testing known as \"DNA Technology in Forensic
Science\".NRC-I deals with the DNA testing using the Restriction Fragment Length
Polymorphism (RFLP).
In 1996, NRC-II report was issued known as \"The Evaluation of Forensic DNA Evidence\".
NRC-II deals with DNA testing using Polymerase chain reaction (PCR).
4. Proper planning of a software project unless the project is trivia.pdf
4. Proper planning of a software project unless the project is trivial in size, is obviously
important for a software project to succeed. What information must be included in software
project planning document? Explain in a paragraph or two (15pt.) 5. Risk management is one of
CMMI KPA (Key Process Area). Explain its concept in a paragraph or two (10pt.)
Solution
Typically many of the project\'s key stakeholders, that is those affected by both the project and
the project\'s end result, do not fully understand the nature of the project plan. Since one of the
most important and difficult aspects of project management is getting commitment and buying,
the first step is to explain the planning process and the project plan to all key stakeholders. It is
essential for them to understand the importance of this set of documents and to be familiar with
its content, since they will be asked to review and approve the documents that pertain to them.
Components of the Project Plan Include:
Baselines. Baselines are sometimes called performance measures, because the performance of
the entire project is measured against them. They are the project\'s three approved starting points
and include the scope, schedule, and cost baselines. These provide the \'stakes in the ground.\'
That is, they are used to determine whether or not the project is on track, during the execution of
the project.
Baseline management plans. These plans include documentation on how variances to the
baselines will be handled throughout the project. Each project baseline will need to be reviewed
and managed. A result of this process may include the need to do additional planning, with the
possibility that the baseline(s) will change. Project management plans document what the project
team will do when variances to the baselines occur, including what process will be followed,
who will be notified, how the changes will be funded, etc.
Other work products from the planning process. These include a risk management plan, a quality
plan, a procurement plan, a staffing plan, and a communications plan.
Step 2: Define roles and responsibilities. Not all key stakeholders will review all documents, so it
is necessary to determine who on the project needs to approve which parts of the plan. Some of
the key players are:
Step 3: Hold a kickoff meeting. The kickoff meeting is an effective way to bring stakeholders
together to discuss the project. It is an effective way to initiate the planning process. It can be
used to start building trust among the team members and ensure that everyone\'s idea are taken
into account. Kickoff meetings also demonstrate commitment from the sponsor for the project.
Here are some of the topics that might be included in a kickoff meeting:
Step 4: Develop a Scope Statement. The Scope Statement is arguably the most important
document in the project plan. It\'s the foundation for the rest of the project. It describes the
project and is used to get common agreement among the sta.

What are the major inputs to the MRP systemSolutionMaterial r.pdf
What are the major inputs to the MRP system?
Solution
Material requirements planning (MRP) is a computer-based inventory management system
designed to assist production managers in scheduling and placing orders for items of dependent
demand. Dependent demand items are components of finished goods—such as raw materials,
component parts, and subassemblies—for which the amount of inventory needed depends on the
level of production of the final product..
Type I alveolar cells(a) allow rapid diffusion of gases through t.pdf
Type I alveolar cells:
(a) allow rapid diffusion of gases through their membranes.
(b) secrete a chemical known as surfactant.
(c) are phagocytic.
(d) A, B, and C.
(e) None of the above.
Solution
(a) allow rapid diffusion of gases through their membranes.
Type I alveolar cells are squamous which gives more surface area to each cell and cover
approximately 90–95% of the alveolar surface. Type I cells are involved in the process of gas
exchange between the alveoli and blood. These cells are extremely thin.These cells need to be so
thin to be readily permeable for enabling an easy gas exchange between the alveoli and the
blood..
The memory cycle times have been much longer than processor cycle ti.pdf
The memory cycle times have been much longer than processor cycle times; this speed gap
between the memory and the processor means that the processor must wait for memory to
respond to an access request. The obvious method of increasing the speed of the memory system
is by using a higher speed memory technology. Once the technology is selected, the access
speeds can be increased further by different address decoding and access techniques. Described
in details at least 3 of them
Solution
The different techniques are:
1. Banking: The main memory is built out of several physical-memory modules. Each and every
module is a memory bank of a certain capacity and consists of a MAR and a MBR. In
semiconductor memories, each module corresponds to either a memory IC or a memory board
consisting of several memory ICs. The consecutive addresses lie in the same bank. If each bank
contains 2n = N words and if there are 2m = M banks in the memor y, then the system MAR
would contain n + m bits.
2. Multiport Memories: Multiple memories are available in which each port corresponds to an
MAR and an MBR . Independent access to the memory can be made from each port. The
memory system resolves the conflicts between the ports on a priority basis. Multiport memories
are useful in an environment where more than one device accesses the memory. Examples of
such systems are a single-processor system with a direct-memory access (DMA), I =O controller,
and a multiprocessor system with more than one CPU.
3.Instruction Buffer: The instruction buffer, Providing a first-in, first-out (FIFO) buffer between
the CPU and the primary memory enhances the instruction fetch speed . Instructions from the
primary memory are fed into the buffer at one end and the CPU fetches the instructions from the
other end. As long as the instruction execution is sequential, the two operations of filling the
buffer and fetching from the buffer into CPU can go on simultaneously. But when a jump
(conditional or unconditional) instruction is executed, the next instruction to be executed may or
may not be in the buffer. The buffer management requires hardware component to manage the
queue and mechanisms to identify the address range in the buffer and to freeze and unfreeze the
buffer. INTEL 8086 processor uses a 6 -byte long instruction buffer organized as a queue. CDC
6600 uses an instruction buffer that can store eight 60-bit words, that is, 16–32 instructions, since
the instructions are either 15- or 30-bits long..
Suppose you land on a previously unexplored South Pacific island. Yo.pdf
Suppose you land on a previously unexplored South Pacific island. You find three novel bird
species. Two are small, one of these specializing in seed eating, the other in eating grubs and
insects. Both show highly camouflaged coloration. The third bird species is substantially larger
and is a dedicated predator; this third species specializes in preying on small rodents and the
other two bird species. Its coat is brightly colored. Which of the following is the statement about
the evolutionary relationships of these three species that we can make with the most confidence?
[\"Relationship\" and \"relatedness\" here refers to phylogenetic history. Closely related species
descended from the same ancestral species recently. In contrast, more distantly related species
last had a common ancestor further in the past
A) We cannot draw any conclusions about phylogenetic relationships of these species based on
the data given; we would need additional data, like insights into selective history or fossil
evidence.
b.We cannot draw any conclusions about phylogenetic relationships of these species based on the
data given; bird evolution works differently than mammalian evolution.
Suppose you are a member of an island population of people that contains about 1000
individuals and that has remained stable in size (with no new immigration) for many dozens of
generations. Now suppose you could time travel into the future 300 years (ten generations).
Which of the answers below is the best description, first, of the fraction of the future population
of the island that are expected to be your descendants (on average) and, second, how closely
related you are to those future descendants in comparison to your relatedness to the other
contemporary residents of the island? [Note that \"relatedness\" here refers to the specific
parameter \"r\" as discussed it in TOPIC 5, that is, \"genetic relatedness\" from the gene\'s
perspective.]
Most or all of the future residents of the island would be my descendants and I would be more
than twice as closely related to them than I am to any randomly chosen member of the
contemporary population.
Approximately 10% of the future population of the island would be my descendants and I would
be roughly 10 times more closely related to them as I am to any randomly chosen member of the
contemporary population.
Most or all of the future residents of the island would be my descendants and I would be no more
closely related to them than I am to any randomly chosen member of the contemporary
population.
d) Approximately 20% of the future population of the island would be my descendants and I
would be roughly 5 times more closely related to them as I am to any randomly chosen member
of the contemporary population.
A) We cannot draw any conclusions about phylogenetic relationships of these species based on
the data given; we would need additional data, like insights into selective history or fossil
evidence.
b.We cannot draw any conclusions abou.
State two factors that have contributed to the development of emergi.pdf
State two factors that have contributed to the development of emerging infectious diseases.
For either Rabies or Anthrax, provide the following information:
1.Causative agent (e.g., viral, bacterial, parasitic)
2.Symptoms (at least two)
3.Geographic distribution
4.Host factors
5.Responsible vector
6.Potential human hazards
7.A method of control
Solution
1. The causative agent of rabies is virus called Rabies virus (RV) or Lyssavirus which is a
negative stranded ribonucleic acid virus belonging to rhabdovirus family.
The causative agent of Anthrax is a bacillus bacterium called Bacillus anthracis which is a large
Gram positive rod shaped aerobic belonging to Rhabdoviridae family.
2. The symptoms of Rabies are initially similar to flu which includes fever, muscle weakness and
tingling. Other symptoms include insomnia, anxiety, excess salivation, hydrophobia, problems in
swallowing etc.
The symptoms of Anthrax are different depending upon the route of infection. The symptoms of
cutaneous anthrax are raised itchy bump like insect bite alongwith swelling in the lymph glands
and sore. The symptoms of gastrointestinal anthrax include nausea,vomiting, headache. loss of
appetite, severe bloody diarrhoea, swollen neck etc. The symptoms of pulmonary anthrax include
flu like symptoms with shortness of breath, coughing up blood, nausea etc.The symptoms of
injection anthrax include redness and swelling of the area of infection, shock,meningitis,
multiple organ failure etc.
3. Rabies is present in mammals in most parts of the world. Per year Most of the estimated 55
000 human rabies deaths occur in Africa and Asia.
Sporadic cases of Anthrax occur in animals worldwide. However there are occasional outbreaks
in Africa, central and southern Asia.
4. Like many rhabdoviruses, Rabies virus has an extremely wide host range. Many mammalian
species in the wild has been found infecting , while in the laboratory it has been found that birds
can be infected, as well as cell cultures from mammals, birds, reptiles and insects.
Anthrax is spread from infectious animal products by contact with the spores of the bacteria.
Contact is by breathing, eating, or through an area of broken skin. It does not typically spread
directly between people.
5. There are three vectors for rabies:
c. Tissue transplants (such as corneas) from infected humans.
In its infectious form, anthrax is a spore that usually populates the soil but which, in rare cases,
can become airborne and inhaled. With cutaneous anthrax, the bacteria infects the host through
direct penetration of the host skin.
It depends on the death of its host for propagation which is different from many pathogenic
organisms. Once the host is dead, its body starts decaying and the bacteria in the bloodstream are
exposed to oxygen. These bacteria turn into spores which populate the surrounding soil.. The
spores can be eaten up by herbivores or from cutaneous infection.
Anthrax does not appear to be transmissable from person to per.

Research and prepare a presentation to demonstrate a scenario in whi.pdf
Research and prepare a presentation to demonstrate a scenario in which object-based storage is a
better choice over SAN and NAS.
Solution
Since there is no privelege to provide you an attachement of slide deck, we are providing you the
scenario based idea in which object-based storage is a better choice over SAN and NAS.So here
it is:
Even though several storage type exists, a single type of storage solution doesnot fit everybody\'s
needs.
Object storage is of major importance (current pretty much good option) in large storage
deployments, especially in the cloud based scenario.
Representing the data may be different from storing data. Also, scaling out storage has strained
both the NAS (Network Attached Storage) and SAN(Storage Attached Networks) storage
models.
SAN is a high speed network that makes connections between storage devices and servers.The
server can only access data on the devices, which are directly attached to it.If server crashes or
anything happens to the server, access to data will fail. There is a limit in the number of storage
devices the server can access. SAN is primarily used for higher performance block level storage
of data.
Network Attached Storage shares files over the network. Not storage devices over the network.
Any server that shares its own storage with others on the network and acts as a file server is an
example for simplest form NAS. NAS devices are computers within themselves and shares their
storage space with others. If you share a folder with access control using SAMBA, its NAS.
NAS is primarily used for long distance small IO operations.
Object storage which is famous in Cloud nowadays is like NAS but not exactly. Here each data
block is replicated on serveral storage disks for integrity. Each of these storage models uses their
own protocols. Object storage - Swift in OpenStack private cloud is good example. Ceph is also
converged storage solution which is gaining momentum at highest rate nowadays.And Object
storage is developer\'s choice where in data can be accessed anytime, easily & anywhere with an
internet connection using REST APIs..

How does friction heating effect pressure dropSolutionHeat tr.pdf
How does friction heating effect pressure drop?
Solution
Heat transfer is not the consequence (or effect) of pressure drop. In the absence of a temperature
gradient, it is possible to have pressure drop in a flow without heat transfer. Similarly, in
unconfined convection over an external surface (imagine flow over a hot flat plate or for more
simplicity, an aircraft flying at altitude), it is possible to have heat transfer without a pressure
drop. (The pressures in front of the aircraft as well as behind the aircraft are the same!)
Both pressure drop and heat transfer are consequences of a velocity gradient. For real fluids, a
velocity gradient produces a shear force which is overcome by a sacrifice of fluid pressure (as in
pipe flow). On the other hand, a velocity gradient gives rise to convective diffusion.
In general, heat transfer is the desired effect while pressure drop is how we pay for that
effect.This relationship is simply and beautifully brought out by the simplest of all analogies, the
Reynolds Analogy. The friction factor fand the Conburn \'j\' factor are related as f/j 2. In other
words, f can never be less than 2 x j.h and f which are convection and friction factor parameters ..
HELP!!! Ive looked up online cut cant seem to find this answer. Use .pdf
HELP!!! Ive looked up online cut cant seem to find this answer. Use any resources available on
the internet to explain the difference between the NRC I and NRC II reports?
Solution
Answer:
NRC :National Resource Council
National Resource Council is first organised in 1916 by National academy of sciences. NRC
deals with criminal cases using DNA testing.
In 1992, NRC-I report was issue about DNA testing known as \"DNA Technology in Forensic
Science\".NRC-I deals with the DNA testing using the Restriction Fragment Length
Polymorphism (RFLP).
In 1996, NRC-II report was issued known as \"The Evaluation of Forensic DNA Evidence\".
NRC-II deals with DNA testing using Polymerase chain reaction (PCR).
4. Proper planning of a software project unless the project is trivia.pdf
4. Proper planning of a software project unless the project is trivial in size, is obviously
important for a software project to succeed. What information must be included in software
project planning document? Explain in a paragraph or two (15pt.) 5. Risk management is one of
CMMI KPA (Key Process Area). Explain its concept in a paragraph or two (10pt.)
Solution
Typically many of the project\'s key stakeholders, that is those affected by both the project and
the project\'s end result, do not fully understand the nature of the project plan. Since one of the
most important and difficult aspects of project management is getting commitment and buying,
the first step is to explain the planning process and the project plan to all key stakeholders. It is
essential for them to understand the importance of this set of documents and to be familiar with
its content, since they will be asked to review and approve the documents that pertain to them.
Components of the Project Plan Include:
Baselines. Baselines are sometimes called performance measures, because the performance of
the entire project is measured against them. They are the project\'s three approved starting points
and include the scope, schedule, and cost baselines. These provide the \'stakes in the ground.\'
That is, they are used to determine whether or not the project is on track, during the execution of
the project.
Baseline management plans. These plans include documentation on how variances to the
baselines will be handled throughout the project. Each project baseline will need to be reviewed
and managed. A result of this process may include the need to do additional planning, with the
possibility that the baseline(s) will change. Project management plans document what the project
team will do when variances to the baselines occur, including what process will be followed,
who will be notified, how the changes will be funded, etc.
Other work products from the planning process. These include a risk management plan, a quality
plan, a procurement plan, a staffing plan, and a communications plan.
Step 2: Define roles and responsibilities. Not all key stakeholders will review all documents, so it
is necessary to determine who on the project needs to approve which parts of the plan. Some of
the key players are:
Step 3: Hold a kickoff meeting. The kickoff meeting is an effective way to bring stakeholders
together to discuss the project. It is an effective way to initiate the planning process. It can be
used to start building trust among the team members and ensure that everyone\'s idea are taken
into account. Kickoff meetings also demonstrate commitment from the sponsor for the project.
Here are some of the topics that might be included in a kickoff meeting:
Step 4: Develop a Scope Statement. The Scope Statement is arguably the most important
document in the project plan. It\'s the foundation for the rest of the project. It describes the
project and is used to get common agreement among the sta.

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.
