A case study of a young man with a viral infection In the late winter of 2009 Jeff, a 19 year old
male, living in the dorms at college came down suddenly with a virus which kept him out of
classes for 3 days. Jeff\'s day started out as a regular day and he went to his classes as he
normally does. As the day went on Jeff began to tired and worn out but he figured it was just due
to a lack of sleep and feel stress. That night he laid down for bed and recognized he was running
a slight fever so he thought he would just sleep it off and feel better in the morning. The next
morning when he awoke he had a high fever, chills, body aches and nausea. Jeff only left his bed
that day to go to the bathroom a couple times fever, or to get a glass of water. As day went on his
symptoms only got worse, by that night his fever chills, and aches were also accompanied by
diarrhea. The next day Jeff then began experiencing it vomiting on top of his current symptoms
and was unable to drink water or eat any food without 2 days making his stomach feel worse. By
that night he was beginning to feel much better, and within 2 days he had almost fully recovered.
What was Jeff suffering from? How do we know this wasn\'t the flu? How should his illness
have been treated? What were his risk factors for becoming infected? How many people are
infected each year in the US with this virus? How can you prevent infection with this virus?
What is the mode of transmission and reservoir for this virus?
Solution
ANSWER:
1) jeff was suffering from Gastroenteritis...
2)We know that was not flu because the symptoms of flu was highfever,bodyaches, chills and
sweat, persistent cough,headache,nasalcongestion,sorethoratand weakness.diarrhea not occur in
flu....
3)Drinking enough fluids, and learning what to eat will keep you comfortable. have to manage
diarrhea,control nausea,and vomiting and get plenty of rest will help to treat disease....
4)RISK FACTORS: Gastroenteritis is caused by the people with weak immune system ,
ingestion of viruses, certain bacteria, or parasites. Food that has spoiled may also cause illness.
Young children may develop signs and symptoms of gastroenteritis as a reaction to a new food.
HIGH RISK FACTORS INCLUDE:
5)It is estimated that three to five billion cases of gastroenteritis resulting in 1.4 million deaths
occur globally each year.IN U.S 10,00O PEOPLE ARE INFECTED......
6)Prevention:Wash your hands after using the toilet and before handling food. Don’t prepare
food for other people until your symptoms improve. Avoid close contact with others during your
illness. After your symptoms stop, try to wait at least 48 hours before returning to work.
You can also help prevent bacterial gastroenteritis infections by avoiding unpasteurized milk,
raw meat, or raw shellfish. Use separate cutting boards and utensils for raw and cooked meats
when preparing meals. Wash salads and vegetables thoroughly. Make sure to store food at either
very hot or very cold temperatures i.
A disease is a condition that impairs the proper function of the body or of one of its parts. Every living thing, both plants and animals, can succumb to disease. Hundreds of different diseases exist.
Each has its own particular set of symptoms and signs, clues that enable a physician to diagnose the problem.
Every disease has a cause, although the accuses of some remain to be discovered. Every disease also displays a cycle of onset, or beginning, course, or time span of affection, and end, when it disappears or it partially disables or kills its victim.
YOUR IMMUNE SYSTEM - Your best weapon and defense against the virus infection is your immune system. In this research keynote slides, you will find ways to boost and strengthen your immunity to fight all odds.

Let D P2(R) P1(R) defined by D(p) = p . Where p is the deriva.pdfarihanthtoysandgifts
Let D : P2(R) P1(R) defined by D(p) = p\' . Where p\' is the derivative of p. Find the null space
of D. Is this map injective ?
Solution
Any constant scaling of that function will be zero as well.
Since the null space is not just 0, then any two vectors in the null space map to zero, thus it
cannot be one one.
T(1,x,x2) = (0,1,x) The transformation doesn\'t contain the {0} therefore null D 0 therefore the
map is not injective..
Islam and Supply-Side EconomicsSupply-side economics has a long hi.pdfarihanthtoysandgifts
Islam and Supply-Side Economics
Supply-side economics has a long history, dating back to at least the fourteenth century. The
greatest of medieval historians, Abu Zayd Abd-ar-Rahman Ibn Khaldun (1332–1406), included
in his book, The Muqaddimah (1377), an Islamic view of supply-side economics. He pointed out
that “when tax assessments . . . upon the subjects are low, the latter have the energy and desire to
do things. Cultural enterprises grow and increase . . . (Therefore) the number of individual
imposts (taxes) and assessments mounts.” If taxes are increased in both size and rates, “the result
is that the interests of subjects in cultural enterprises disappears, because when they compare
expenditures and taxes with their income and gain and see little profit they make, they lose all
hope.” Ibn Khaldun concluded that “at the beginning of a dynasty, taxation yields large revenue
from small assessments. At the end of a dynasty, taxation yields small revenue from large
assessments.”
(A) How do this Islamic scholar’s theories apply to the modern world?
Solution
Ans:
In the course of the most recent 50 years there has been reestablished enthusiasm for Islamic
nations in looking at the relationship in the middle of Islam and science in the range of its
history. In the wake of picking up autonomy the majority of the Islamic nations have been
attempting to deal with their religious convictions and the Western ideas of science and training.
The instruction frameworks embraced by the greater part of the Islamic nations have been
founded on supposed common Western training. Subsequently a social dichotomy is seen in their
social orders between a conventional Islamic training from one viewpoint confined to religious
gatherings, and a common Western instruction in standard schools, schools and colleges.
Training is seen as a method for securing logical learning and innovation, so as to advance
monetarily in the cutting edge world. On the other hand, training has unsuccessfully attempted to
mix Islamic thinking with this Western instruction framework.
Islamic Nature view :
The Islamic perspective of nature amid the Golden Age was for humankind \'to study nature with
a specific end goal to find God and to utilize nature for the advantage of humanity\'. Nature
could be utilized to give sustenance to humankind and its abundance was to be similarly
circulated among all people groups. All exercises that made damage humanity and thus
devastated nature were illegal. Devastation of the common equalization was disheartened, for
instance, pointless executing of creatures or evacuation of vegetation may thus prompt starvation
because of absence of nourishment. This perspective was an expansion of the thought that
\"man\" had been set on earth as God\'s illustrative.
Supply-side financial aspects is a macroeconomic hypothesis which contends that monetary
development can be most adequately made by putting resources into capital, and by bringing
down boundaries on the .

Increasingly there is political discussion in carbon dioxide as well.pdfarihanthtoysandgifts
Increasingly there is political discussion in carbon dioxide as well as CO as a pollutant. Clearly
all hydrocarbons have CO2 as a product. Discuss how coal and methane rate in terms of carbon
dioxide.
Solution
The amount of CO2 produced when a fuel is burned is a function of the carbon content of the
fuel. The heat content, or the amount of energy produced when a fuel is burned, is mainly
determined by the carbon (C) and hydrogen (H) content of the fuel. Heat is produced when C and
H combine with oxygen (O) during combustion. Natural gas is primarily methane ( CH4), which
has a higher energy content relative to other fuels, and thus, it has a relatively lower CO2-to-
energy content. Water and various elements, such as sulfur and non-combustible elements in
some fuels reduce their heating values and increase their CO2-to-heat contents..

In January 2017, Bramble Corp., a newly formed company, issued 10400.pdfarihanthtoysandgifts
In January 2017, Bramble Corp., a newly formed company, issued 10400 shares of its $8 par
common stock for $13 per share. On July 1, 2017, Bramble Corp. reacquired 1040 shares of its
outstanding stock for $10 per share. The acquisition of these treasury shares
increased total stockholders\' equity.
Solution
If company acquired treasury stock then company\'s total stockholder\'s equity decreased in total.
but does not decrease number of issued shares but decrease no. of outstanding share.
If company acquired treasury shares then (1040*10) = 10400
then total stockholder\'s equity decreased by $10400
so answer is d) decreased total stockholders\' equity..

Identify the unique characteristics of auditing professionSoluti.pdfarihanthtoysandgifts
Identify the unique characteristics of auditing profession
Solution
ANSWER:
Auditing refers to evaluating the effectiveness of a company\'s internal controls. An audit is an
assessment of an individual, process, system, firm, organization, institution, company, project, or
product. Audits are carried out to check and verify the reliability of any given information and
give an evaluation of the internal control of the system.
Unique Characteristics of auditing profession:
--Pursue goals: A unique auditing profession is a important because it facilitates to pursue for the
attainment of several corporate purposes. It helps to prevent and identify irregular transaction,
measure the performance of the corporate, maintain adequate business records and to enhance
the productivity.
--Fraud Prevention: Auditing serves vital role for companies in the prevention of fraud.
Recurring analysis of the operations and maintaining rigorous systems in the company can
prevent and detect various forms of accounting irregularities and other fraud activities. Audit
professionals helps in the design and modification of the control systems the purpose of which
includes, among other things, prevention of fraud.
-- Cost of Capital: Unique audit systems profession reduces the several forms of risk in an
enterprise, including its information risk (the risk of material misstatement in financial
reporting), the risk of suboptimal management due to insufficient information on its operations
and also the risk of fraud and misappropriation of assets.
--Prevents debilitating misstatements: A unique auditing system helps in preventing debilitating
misstatements in a company’s records and reports
--A thirst for knowledge: Auditors needs to strive to cultivate a deep knowledge of the company
consisting of its culture, key players and competitive environment. It is main factor that is
guaranteed to set audit apart from other auditing and risk compliance professionals
--Innovation: Every company has its own inner workings and to be a unique auditing manager or
compliance officer needs creativity. Combine innovation with current company\'s processes to
provide impressive results.
--Communication/People skills: The ability to read people and adapt for any given situation is a
key driver in those who progress up the internal or external auditing career ladder effectively..
Hemophilia is a recessive trait. The dominant trait is normal blood d.pdfarihanthtoysandgifts
Hemophilia is a recessive trait. The dominant trait is normal blood dotting A gene that can cause
hemophilia is located on the X chromosome. If a homozygous normal female marries a normal
male, they children might have which of the following phenotypes: Select one: a. normal
females, hemophiliac females, and hemophiliac males. b. normal females, hemophiliac females,
normal males, and hemophiliac males. c. normal females and hemophiliac males d. normal
females and normal mates. e. normal females, normal males or hemophiliac males.
Solution
In X - linked recessive inheritance males are more prone to disease because they carry the
disease trait. If the affected offspring’s mother has brother or father containing the same trait
then the mother pass the trait to her offspring. The affected males produce unaffected daughters
who can produce 50% affected sons. Hemophilia is the example of X - linked recessive trait.
When a homozygous normal female marries to a normal male the offspring produced are normal
females and normal males. Option d is correct..
Explain the purpose of the Medium Access Control (MAC) timing paramet.pdfarihanthtoysandgifts
Explain the purpose of the Medium Access Control (MAC) timing parameters Short InterFrame-
Space (SIFS), Point (coordination function) Interframe Space (PIFS), and Distributed
(coordination function) Interframe Space (DIFS). Explain why they should be carefully chosen.
Why has a station at least to wait one DIFS prior to transmission?
Solution
Answer
The purpose of the given MAC timing parameters are as below:
SIFS : Short Interframe Space, is the amount of time in microseconds needed by a wireless
interface to process a received frame and to respond with a response frame. It is given by the
difference in time of the first symbol of the response frame in the air and the last symbol of the
received frame in the air. A SIFS time comprises of the delay in receiver RF, PLCP delay and the
MAC processing delay, which depends on the physical layer used.
Point (co-ordination function) Interframe Space: it co-ordinates the communication within a
network.It is the time or duration for which PCF waits to grasp a channel.
Distributed (co-ordination function) Interface Space: it controls the access to the physical
medium. If DFC protocol finds that the medium is continuously idle for DIFS duration, it is then
permitted to transmit a frame. If during the DIFS interval the channel is found busy then that
channel is discarded and another channel is looked for.
A station has to wait for atleast one DIFS prior to transmission because generally it waits for
PIFS duration which is of shorter duration than DIFS and if PIFS is not available it moves to
DIFS duration which gets lapsed if a channel is not found. Therefore, atleast one DIFS duration
wait is required to know if a channel is found for the transmission or not..
explain why HCO3- levels can be calculated from pH and pCO2 levels.pdfarihanthtoysandgifts
explain why HCO3- levels can be calculated from pH and pCO2 levels
Solution
pH is defined as the negative log of the Hydrogen ion concentration: -log[H+].
(also, pH=pK+log [HCO3]/ 0.03 x pCO2). The pH is the product of two components,
respiratory and metabolic, thus allowing for the effect of the pCO2, ie, any change in the pH
unexplained by the pCO2 resulting ina metabolic abnormality.
CO2 and water combine to form carbonic acid or H2CO3, present with concentrations of
bicarbonate (HCO3-)and hydrogen ions (H+) in equilibrium amounts. A change in the
concentration of the reactants on either side of the equation affects the subsequent direction of
the reaction. Eg., a rise in CO2 will also raise carbonic acid formation (H2CO3) which leads to
raised levels of both HCO3- and H+ (\\pH)..
Describe the arrangement of neurons in the primary motor cortexS.pdfarihanthtoysandgifts
Describe the arrangement of neurons in the primary motor cortex
Solution
The primary motor cortex or M1 is found to be located in the dorsal portion of the frontal lobe in
the brain.
This is the region which is involved in coding force and direction of movement and M1 works
along with posterior parietal cortex, premotor cortex, the supplementary motor area etc to
execute its actions.
In M1 region we can find Betz cells (large neurons) along with other cortical neurons, these will
send long axons till the end of the spinal cord, so that they can synapse onto the interneuron
circuitry of the spinal cord. They also send neurons on the alpha motor neurons located in the
spinal cord to have connection with the muscles.
Using Golgi method, the morphology and the spatial arrangement of neurons in the primary
motor cortex has been studies, which revealed the presence of great variety of pyramidal and
non-pyramidal cells in M1 region and main difference between these cells is due to their
difference in shape, size and also with respect to dimensions and distribution of dendritic trees.
It has been reported that columnar aggregation formed were observed in sub-layers III b and c,
formed by the somata and dendritic trees of pyramidal and non-pyramidal cells, these are 100-
300 micron wide and are found to be separated by cell-sparse spaces of 50-100 micron width.
In these aggregations, we can find several bundles formed by apical dendrites of pyramidal cells.
The columnar width was not surpassed by most non-pyramidal cells of dendrites.
In layers III and V, the dendrites and somata of pyramidal cells were found to be showing a
preferential orientation in the same direction and they will run parallel to the main axis of the
gyrus.
But in layers II, IV, and V, what aggregations we found in layer III were not found but in layer
V, around the giant Betz cells, there was a loose assemblage of neurons of all sizes group were
found to be located.
The radii of myelinated fibers entering and leaving the white matter were found to be forming
radial appearance in Layer VI.
The vertical, columnar organization and the asymmetry of somata and dendritic trees were found
to be more pronounced when it comes to the boundary of the central sulcus and boundary of
precentral gyrus..

THE FORMULA TO BE USED IS
V=U+AT...WHERE
V=FINAL VELOCITY....FT/SEC.
U=INITIAL VELOCITY....FT/SEC.
A = ACCELERATION ..HERE IT IS DUE TO GRAVITY WHICH IS ACTING AGAINST
THE MOTION ..ITS VALUE IS -32 FT/SEC.SEC.
T=TIME OF TRAVEL...SEC
WE HAVE U=?
V=0....AS IT REACHED THE HIGHEST POINT AND WILL STOP AND FALL BACK
FROM THERE.
T=2.5 SEC.
0=U-32*2.5
U=32*2.5=80 FT/ SEC.
IF YOU ARE IN MKS UNITS THEN A=-9.8 M/SEC.SEC
U=9.8*2.5=24.5 M/SEC.

Embracing GenAI - A Strategic ImperativePeter Windle
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.

A case study of a young man with a viral infection In the late winte.pdf
1. A case study of a young man with a viral infection In the late winter of 2009 Jeff, a 19 year old
male, living in the dorms at college came down suddenly with a virus which kept him out of
classes for 3 days. Jeff's day started out as a regular day and he went to his classes as he
normally does. As the day went on Jeff began to tired and worn out but he figured it was just due
to a lack of sleep and feel stress. That night he laid down for bed and recognized he was running
a slight fever so he thought he would just sleep it off and feel better in the morning. The next
morning when he awoke he had a high fever, chills, body aches and nausea. Jeff only left his bed
that day to go to the bathroom a couple times fever, or to get a glass of water. As day went on his
symptoms only got worse, by that night his fever chills, and aches were also accompanied by
diarrhea. The next day Jeff then began experiencing it vomiting on top of his current symptoms
and was unable to drink water or eat any food without 2 days making his stomach feel worse. By
that night he was beginning to feel much better, and within 2 days he had almost fully recovered.
What was Jeff suffering from? How do we know this wasn't the flu? How should his illness
have been treated? What were his risk factors for becoming infected? How many people are
infected each year in the US with this virus? How can you prevent infection with this virus?
What is the mode of transmission and reservoir for this virus?
Solution
ANSWER:
1) jeff was suffering from Gastroenteritis...
2)We know that was not flu because the symptoms of flu was highfever,bodyaches, chills and
sweat, persistent cough,headache,nasalcongestion,sorethoratand weakness.diarrhea not occur in
flu....
3)Drinking enough fluids, and learning what to eat will keep you comfortable. have to manage
diarrhea,control nausea,and vomiting and get plenty of rest will help to treat disease....
4)RISK FACTORS: Gastroenteritis is caused by the people with weak immune system ,
ingestion of viruses, certain bacteria, or parasites. Food that has spoiled may also cause illness.
Young children may develop signs and symptoms of gastroenteritis as a reaction to a new food.
HIGH RISK FACTORS INCLUDE:
5)It is estimated that three to five billion cases of gastroenteritis resulting in 1.4 million deaths
occur globally each year.IN U.S 10,00O PEOPLE ARE INFECTED......
6)Prevention:Wash your hands after using the toilet and before handling food. Don’t prepare
food for other people until your symptoms improve. Avoid close contact with others during your
illness. After your symptoms stop, try to wait at least 48 hours before returning to work.
You can also help prevent bacterial gastroenteritis infections by avoiding unpasteurized milk,
2. raw meat, or raw shellfish. Use separate cutting boards and utensils for raw and cooked meats
when preparing meals. Wash salads and vegetables thoroughly. Make sure to store food at either
very hot or very cold temperatures if you’re storing them for more than a couple of
hours.drinking bottled water while traveling abroad and getting recommended vaccines...
7)MODE OF TRANSMISSION AND RESERVOIR:Rotavirus is transmitted predominantly via
the faecal–oral route. Rotavirus has been detected in respiratory secretions. Because the virus is
stable in the environment, transmission can occur through ingestion of contaminated water or
food, and contact with contaminated surface.
HUMANS ARE THE RESERVIORS FOR THE VIRUS.....
