Describe the stages of malaria and the site of protozoal activity on.pdf
Describe the stages of malaria and the site of protozoal activity on each.
Solution
The life cycle is almost the same for all the five species that infect humans and follows three
stages:
(I) ifection of a human with sporozoites
(II) asexual reproduction
(III) sexual reproduction
The human contamination starts The point when a contaminated female anopheles mosque
nibbles an individual and injects contaminated with sporozoites spit under the blood coursing
library. That is the principal existence stage of plasmodium (stage from claiming infection).
The following phase done intestinal sickness life cycle may be the a standout amongst agamic
generation that is isolated under different phases: those pre- erythrocytic (or better,
exoerythrocytic) and the erythrocytic period. Inside best 30- 60 minutes after those parasites
inoculation, sporozoites Figure their approach through blood coursing library will their principal
target, those liver. Those sporozoites enter the liver phones Also start isolating prompting
schizonts creation in 6- 7 days. Each schizont provides for conception on many merozoites
(exoerythrocytic schizogony) that need aid At that point discharged under the blood stream
checking those end of the exoerythrocytic period of the agamic regenerative stage.
It is worth specifying that, concerning p. Vivax and p. Ovale, sporozoites might not take after the
propagation cost step and sit tight lethargic (hypnozoites) in the liver; they might be actuated
then afterward quite a while prompting relapses entering those blood stream (as merozoites)
following weeks, months alternately Significantly A long time. Those exoerythrocytic stage may
be not pathogenic Also doesn\'t prepare manifestations alternately indications of the malady. Its
span may be not the same to the greater part parasite species.
Merozoites discharged under the blood stream, are guided towards their second target, those red
platelets (RBCs). Concerning illustration they attack under those cells, they Stamp those starting
of the erythrocytic stage. Those 1st stage after intrusion may be a ring stage that evolves under a
trophozoite. The trophozoites would not capable on digest the haem Along these lines they
change over it clinched alongside haemozoine Furthermore digest the globin that is utilized
Concerning illustration a hotspot from claiming aminoacids for their propagation cost. The
following cell division stage is those erythrocytic schizont (initially adolescent et cetera full
grown schizont). Each develop schizont provides for conception should new era merozoites
(erythrocytic schizogony) that, after RBCs rupture, are discharged in the blood stream in place
will attack different RBCs. This is At parasitaemia happens Furthermore cinical manifestations
show up. Those liver period happens main When same time those erythrocytic stage undergoes
various cycles; the merozoites arrival then afterward every cycle makes the febrile waves.

and Thelma quickly made arrangements to purchase the business, and Hoosier Burger Restaurant
was born. The restaurant is moderately sized, consisting of a kitchen, dining room, coun- 1-27
ter, storage area, and office. Currently, all paperwork is done by hand. Thelma and Bob have
discussed the benefits of purchasing a computer system; however, Bob wants to in- vestigate
alternatives and hire a consultant to help them. Perishable food items, such as beef patties, buns,

Solution
Part a
There are four phases in the SDLC: planning and selection, analysis, design, and
implementation/operation.
Planning and Selection
The planning and selection phase of the SDLC is utilized once the need for a new or upgraded
information system has been recognized. In regards to Hoosier Burger, Bob Mellankamp, the
owner, has expressed the desire to computerize their information systems; however he is open to
other alternatives as well.
Analysis
The Analysis phase of the SLDC evaluates the current system and then establishes alternative
options to best suit the needs of the organization. In regards to Hoosier Burger, the analysis
should be centered on the organization’s current procedures in the handling of forecasting
information, inventory usage, and basic sales information
Design
The design phase of the SLDC is meant to take into consideration the needs of the business
owner, and the specifics they are looking for in their information systems. In regards to the
Hoosier Burger case, an example of this would be ensuring that the logical and physical designs
of the new system will provide access to the point of sales information as requested by the
owners.
Implementation and Operation
In regards to Hoosier Burger, implementation and operation of the new system would require the
ability to make changes in the system depending on the needs of the owners.
Part B
Major system characteristics and examples are:
Part C
The success of any organization depends on the interactions between its subsystems. The text
states, “Breaking the subsystems down into their components reveals even more about the inner
workings of the system and greatly enhances our understanding of how the overall system
works,” The vital subsystems in regards to Hoosier Burger include the register and sells, food
inventory, food preparation, and data reports. The register allows the system to operate, the food
inventory allows for the sales to be made, the food preparation allows for customers to purchase

Write a program that converts an infix expression into an equivalent.pdf
Write a program that converts an infix expression into an equivalent postfix expression. The
rules to convert an infix expression into an equivalent postfix expression are as follows (C++):
Initialize pfx to an empty expression and also initialize the stack.
Get the next symbol, sym, from infx.
If sym is an operand, append sym to pfx.
If sym is (, push sym into the stack.
If sym is ), pop and append all of the symbols from the stack until the most recent left
parentheses. Pop and discard the left parentheses.
If sym is an operator:
Pop and append all of the operators from the stack to pfx that are above the most recent left
parentheses and have precedence greater than or equal to sym.
Push sym onto the stack.
After processing infx, some operators might be left in the stack. Pop and append to pfx
everything from the stack.
In this program, you will consider the following (binary) arithmetic operators: +, -, *, and /.
You may assume that the expressions you will process are error free. Design a class that stores
the infix and postfix strings. The class must include the following operations:
getInfix: Stores the infix expression.
showInfix: Outputs the infix expression.
showPostfix: Outputs the postfix expression.
convertToPostfix: Converts the infix expression into a postfix expression. The resulting postfix
expression is stored in pfx.
precedence: Determines the precedence between two operators. If the first operator is of higher
or equal precedence than the second operator, it returns the value true; otherwise, it returns the
value false.

Write a Java program that mimics the framework for an online movie i.pdf
Write a Java program that mimics the framework for an online movie information system similar
to IMDB written in Java. Create an abstract base class, two subclasses, and one interface to
provide basic functionality for the system. Use the provided UML, the class descriptions, and the
test output to determine the proper behavior for your classes.
Create an interface Rateable that: Provides a method vote(int numVotes, int voteScore).
Create an abstract class Movie that: Implements the Rateable and Comparable interfaces.
Provides the data fields: title, releaseYear, genre, numVotes, and voteScore. Provides four
constructors: o Default, no-arg constructor o Three convenience constructors that allow as
parameters: the title the title and releaseYear the title, releaseYear, and genre. Provides an
abstract getInfo() method. Provides a concrete toString() method that returns the only movie
title. Provides a concrete getRating() method that returns: o -1 if numVotes is 0, o
voteScore/numVotes otherwise. Implements the Rateable interface’s vote() method by
increasing the existing values of numVotes and voteScore by the amount passed in the
appropriate parameter. Implements the Comparable interface’s compareTo() method by
comparing ratings. Movies should be sorted in descending order, meaning that a higher rating
should be considered “less than” a lower rating.
Create a concrete class Horror that: Automatically sets the genre to Horror in its constructors.
Adds a data attribute for number of deaths, numOfDeaths, with the appropriate getter/setter
methods.
2
Provides a getInfo() method that returns “title, genre, releaseYear (rating): numDeaths deaths”
with the appropriate values. o Detects if it receives a -1 from getRating() and uses “No ratings”
as the rating. o To pass LiveLab’s auto-grader, make sure ratings are limited to one decimal
place (see documentation on using String.format() which works similar to System.out.printf()).
Create a concrete class Comedy that: Automatically sets the genre to Comedy in its
constructors. Adds a data attribute, hasProfanity, to indicate whether there is profanity in the
film with the appropriate getter/setter methods. Provides a getInfo() method that returns “title,
genre, releaseYear (rating): Profanity/No Profanity” with the appropriate values. o Detects if it
receives a -1 from getRating() and use “No ratings” as the rating. o To pass LiveLab’s auto-
grader, make sure ratings are limited to one decimal place (see documentation on using
String.format() which works similar to System.out.printf()).
NOTE: Movie, Horror, and Comedy should provide all of the appropriate accessor/mutator
methods for their data fields. For brevity, these are not included in the UML.
Main method Create the horror movies: o A Nightmare on Elm Street, 1984, 4 deaths o Final
Destination 5, 2011, 94 deaths1 o Saw, 2004, 6 deaths Create the comedy movies: o Napoleon

Which microtubule (MT) population binds to chromosomes during mitosi.pdf
Which microtubule (MT) population binds to chromosomes during mitosis?
Interpolar MTs
Kinetochore MTs
Astral MTs
Either MT population is able to bind chromosomes because they are functionally redundant
MTs do not associate with chromosomes at all
Solution
a)Astral microtubules: These originate at the poles of the cells near the membrane of the cell and
assist in the orientation or the arrangement of the spindle apparatus.
b) polar microtubules: These are longest extending from one end of the cell to the other end and
intertwine with each other and help n seperation of the cells.
c) Kinetochore microtubulues: these are the only tubules which are directly attached to the
chromosomes during the mitosis.As the name indicates these are attached to the kinetochore
region of the chromosome and help in seperaation of chromosomes into two..
React to the following statement Knowledge is the technology wh.pdf
React to the following statement:
Knowledge is the technology which has increased globalization. Thus, globalization then leads
to the need for increased education.
Solution
Globalization:
Globalization is a process of interaction and integration among the people, companies,
and governments of different nations, a process driven by international trade and investment and
aided by information technology.
Knowledge is the technology – globalization:
Technology has also enabled the world to become more interconnected, beyond the
economic sphere, with greater access to information and communication which is having a
profound impact on societies.
Information technology was necessary to enable globalisation and this technology
emerged from developed countries. It changed the economic relationship between countries
because it made knowledge an increasingly important component in the production of goods and
services. Knowledge and high tech industries are the fastest growing in the world today and for
countries to compete in these sectors they need to invest substantially in education and training.
Technology has typically been introduced to developing countries by large multi-
national companies doing business there and so the technology used has originated in developed
countries, where most of these companies’ research and development takes place. Many argue
that this is increasing the power of the MNCs in international markets and weakening the
bargaining power of developing countries.
According to the United Nations Educational, Scientific and Cultural Organization
(UNESCO) in their 2009 World Conference on Higher Education report, Over 2.5 million
students were studying outside their home country. UNESCO also predicted that the number of
international students might rise approximately to 7 million by the year 2020. The main
destinations preferred by international students are the United States, United Kingdom,
Germany, France, Canada and Australia. Overall, the number of international students more than
doubled to over 2 million between 2000 and 2007. However the sharpest percentage increases of
international students have occurred in New Zealand, Korea, the Netherlands, Greece, Spain,
Italy and Ireland.
Globalization and Education:
According to Edward Fiske, “If Americans are to continue to prosper and to exercise
leadership in this new global context, it is imperative that we understand the new global forces
that we have both shaped and had thrust upon us. The alternative is to be at their mercy”.
The effects of globalization have been far-reaching. While the living standards of the
world are still highly uneven, 400 million people have moved out of extreme poverty since
1980—more than at any other time in human history. The growth and urbanization of a global
middle class is creating huge new markets for goods and services of all kinds.
Globalization is often viewed as a zero-sum game in which one nation\'s economic
growth comes at the expense.

Evidence of the oldest fossil of multicellular organisms was seemed to be made by smooth,
wormlike organisms and are known as furrows. These fossils tell us very less about the animals
they belong to except there external shape. The fossils of first large, complex multicellular
organisms who were still soft-bodied were found for the first time in Ediacaran organisms(they
are named after the place they are found), these organisms resembled modern day jellyfish or
worms and disappeared later. In their places, animals of all the modern phyla evolved like
jellyfish, corals, sponges, molluscs, flatworms, annelid worms, echinoderms, insects and
chordates consisting of both soft and hard body parts. Jawless fish were the one to have consist
of skull and were place in vertebrates during the evolution. Arthropods were the first land
animals and bony fish and sharks the first water animals to be comprised of true exoskeleton..

Solution
Public Company Accounting Oversight Board has been established as a part of the Sarbanes and
Oxley Act , 2002 with a view to protect investors interest in public companies through a
oversight over companies accounting and auditing practices. PCAOB is mainly focused on
implementing effective auditing practices, improving audit quality and maintain public trust in
the financial and auditing reports.
The Sarbanes and Oxley Act 2002, passed after major financial crimes such as Enron is a United
States Federal Law. It has eleven titles and establishes corporate accountability and civil and
criminal liabilities for white collar crimes. Title 1 contains provisions of the Public Company
Accounting Oversight board.
Some of the major provisions of the Act are :
(i) It requires public companies to evaluate and disclose the functioning of internal controls and
independent auditors have to agree to such disclosure.
(ii) Financial reports are to be certified by the Chief Financial Officer and Chief Executive
Officer.
(iii) Auditor independence , and outrightly prohibits any non audit work which can be carried out
by an independent auditor.
(iv) Prohibits personal loans to directors of the companies
(v) Accelerated reporting of insider trading
(vi) It also requires public companies to have an indepedent audit committee to oversee the
relationship between auditor and the company
(vii) Enhanced criminal and civil liabilities for any violations.

Microprocessor An alarm system is to have 4 different devices, ea.pdf
Microprocessor An alarm system is to have 4 different devices, each with its sensor. One of the
sensors is to have interrupt address 83. Show and explain how that address is created using
switches and how the INTA signal is used to enable a tri-state buffer/driver to place the address
on the data lines.
Solution
Sometimes in digital electronic circuits we need to isolate logic gates from each other or have
them drive or switch higher than normal loads, such as relays, solenoids and lamps without the
need for inversion. One type of single input logic gate that allows us to do just that is called the
Digital Buffer.
Unlike the single input, single output inverter or NOT gate such as the TTL 7404 which inverts
or complements its input signal on the output, the “Buffer” performs no inversion or decision
making capabilities (like logic gates with two or more inputs) but instead produces an output
which exactly matches that of its input. In other words, a digital buffer does nothing as its output
state equals its input state.
Then digital buffers can be regarded as Idempotent gates applying Boole’s Idempotent Law
because when an input passes through this device its value is not changed. So the digital buffer is
a “non-inverting” device and will therefore give us the Boolean expression of: Q = A..
List three branches of the United States government and write a sent.pdf
List three branches of the United States government and write a sentence for each that describes
its function
Solution
The three separate branches of government: the legislative, the executive and the judicial.
Legislative Branch
The legislative branch is made up of the two houses of Congress—the Senate and the House of
Representatives. The most important duty of the legislative branch is to make laws. Laws are
written, discussed and voted on in Congress.
Executive Branch
The President is the head of the executive branch, which makes laws official. The President is
elected by the entire country and serves a four-year term. The President approves and carries out
laws passed by the legislative branch. He appoints or removes cabinet members and officials. He
negotiates treaties, and acts as head of state and commander in chief of the armed forces.
The executive branch also includes the Vice President and other officials, such as members of
the cabinet. The cabinet is made up of the heads of the 15 major departments of the government.
The cabinet gives advice to the President about important matters.
Judicial Branch
The judicial branch oversees the court system of the U.S. Through court cases, the judicial
branch explains the meaning of the Constitution and laws passed by Congress. The Supreme
Court is the head of the judicial branch. Unlike a criminal court, the Supreme Court rules
whether something is constitutional or unconstitutional—whether or not it is permitted under the
Constitution..
John is 5 years old and was diagnosed with cystic fibrosis following.pdf
John is 5 years old and was diagnosed with cystic fibrosis following intestinal obstruction after
birth. He has frequent infections despite respiratory therapy. Answer the following question
regarding Cystic Fibrosis.
1)John’s parents would like to have another child. What is the probability that the child will have
cystic fibrosis?
2)Describe the basic pathophysiology of cystic fibrosis and the effects in the body.
3)What are the effects on airflow of mucus obstruction in the lungs?
4)Why does John have frequent infections?
5)Why does John have fluid-electrolyte imbalances particularly when experiencing a high fever?
Solution
1) Since Cystic Fibrosis is an autosomal recessive disease, the chances of its occurrence are 1 in
four births. John\'s first child is having Cystic Fibrosis, still, the chance is 25% for the next child
to have the disease. The child may or may not have cystic fibrosis.
2) In cystic fibrosis, there is a mutation in the CFTR gene and different mutation in the gene
cause different protein formation which results in mild or severe disease. The gene is responsible
for the formation of a protein that anchors on the outer walls of the exocrine glands including
lungs, pancreas and sweat glands. The encoded protein creates a channel which is responsible for
the movement of halogens from inside and outside of the body. the nonfunctioning of the protein
results in the blockage of the channels of the affected organs and causes infection and
remodeling of the lungs. There is damage in the digestive system due to the accumulation of
digestive enzymes. Due to this, there are chances that the patient will acquire chronic infection
and proliferation of bacteria in the accumulated mucus in the lungs.
3) The airflow in the lungs gets affected in cystic fibrosis as there is deposition of mucus in the
small airways of the lungs. Since the mucus gets lined is dehydrated and is difficult to clear and
eventually obstructs the air pathway causing the destruction in alveoli and deposition of foreign
particles in the airways. This can lead to frequent chronic infections.
4) The reason behind the frequent infection of John is the mucus deposition in the air pathways
which leads to the proliferation of bacteria in the nutrient-rich mucus. These bacteria forms
biofilms inside which is difficult for the immune cells to penetrate and which makes the
condition severe.
5) This condition of John is due to the improper transfer of ions in the body due to the narrowing
of the channels. This gets severe as the body fights with the soaring body temperature as well as
the defect in the channels of ions transport..

and we should come together to save the effected people.
yes, in the last decade we faced many natural calamities like, Tsunamis, Earthquaques, Heavy
rains and floods and so on. there are some people who have taken insurance and there are some
who does not taken insurance. but irrespective of all these one should come forward to help them
and to support them to recover. we can not minimise the loss what happend, but we can support
them to recover faster.
individuals, organisations and nations also should come forward to save the effected people, it is
humanity and no one deny or object it..

Write a Java program that mimics the framework for an online movie i.pdf
Write a Java program that mimics the framework for an online movie information system similar
to IMDB written in Java. Create an abstract base class, two subclasses, and one interface to
provide basic functionality for the system. Use the provided UML, the class descriptions, and the
test output to determine the proper behavior for your classes.
Create an interface Rateable that: Provides a method vote(int numVotes, int voteScore).
Create an abstract class Movie that: Implements the Rateable and Comparable interfaces.
Provides the data fields: title, releaseYear, genre, numVotes, and voteScore. Provides four
constructors: o Default, no-arg constructor o Three convenience constructors that allow as
parameters: the title the title and releaseYear the title, releaseYear, and genre. Provides an
abstract getInfo() method. Provides a concrete toString() method that returns the only movie
title. Provides a concrete getRating() method that returns: o -1 if numVotes is 0, o
voteScore/numVotes otherwise. Implements the Rateable interface’s vote() method by
increasing the existing values of numVotes and voteScore by the amount passed in the
appropriate parameter. Implements the Comparable interface’s compareTo() method by
comparing ratings. Movies should be sorted in descending order, meaning that a higher rating
should be considered “less than” a lower rating.
Create a concrete class Horror that: Automatically sets the genre to Horror in its constructors.
Adds a data attribute for number of deaths, numOfDeaths, with the appropriate getter/setter
methods.
2
Provides a getInfo() method that returns “title, genre, releaseYear (rating): numDeaths deaths”
with the appropriate values. o Detects if it receives a -1 from getRating() and uses “No ratings”
as the rating. o To pass LiveLab’s auto-grader, make sure ratings are limited to one decimal
place (see documentation on using String.format() which works similar to System.out.printf()).
Create a concrete class Comedy that: Automatically sets the genre to Comedy in its
constructors. Adds a data attribute, hasProfanity, to indicate whether there is profanity in the
film with the appropriate getter/setter methods. Provides a getInfo() method that returns “title,
genre, releaseYear (rating): Profanity/No Profanity” with the appropriate values. o Detects if it
receives a -1 from getRating() and use “No ratings” as the rating. o To pass LiveLab’s auto-
grader, make sure ratings are limited to one decimal place (see documentation on using

Which microtubule (MT) population binds to chromosomes during mitosi.pdf
Which microtubule (MT) population binds to chromosomes during mitosis?
Interpolar MTs
Kinetochore MTs
Astral MTs
Either MT population is able to bind chromosomes because they are functionally redundant
MTs do not associate with chromosomes at all
Solution
a)Astral microtubules: These originate at the poles of the cells near the membrane of the cell and
assist in the orientation or the arrangement of the spindle apparatus.
b) polar microtubules: These are longest extending from one end of the cell to the other end and
intertwine with each other and help n seperation of the cells.
c) Kinetochore microtubulues: these are the only tubules which are directly attached to the
chromosomes during the mitosis.As the name indicates these are attached to the kinetochore
region of the chromosome and help in seperaation of chromosomes into two..
React to the following statement Knowledge is the technology wh.pdf
React to the following statement:
Knowledge is the technology which has increased globalization. Thus, globalization then leads
to the need for increased education.
Solution
Globalization:
Globalization is a process of interaction and integration among the people, companies,
and governments of different nations, a process driven by international trade and investment and
aided by information technology.
Knowledge is the technology – globalization:
Technology has also enabled the world to become more interconnected, beyond the
economic sphere, with greater access to information and communication which is having a
profound impact on societies.
Information technology was necessary to enable globalisation and this technology
emerged from developed countries. It changed the economic relationship between countries
because it made knowledge an increasingly important component in the production of goods and
services. Knowledge and high tech industries are the fastest growing in the world today and for
countries to compete in these sectors they need to invest substantially in education and training.
Technology has typically been introduced to developing countries by large multi-
national companies doing business there and so the technology used has originated in developed
countries, where most of these companies’ research and development takes place. Many argue
that this is increasing the power of the MNCs in international markets and weakening the
bargaining power of developing countries.

Public Company Accounting Oversight Board has been established as a part of the Sarbanes and
Oxley Act , 2002 with a view to protect investors interest in public companies through a
oversight over companies accounting and auditing practices. PCAOB is mainly focused on
implementing effective auditing practices, improving audit quality and maintain public trust in
the financial and auditing reports.
The Sarbanes and Oxley Act 2002, passed after major financial crimes such as Enron is a United
States Federal Law. It has eleven titles and establishes corporate accountability and civil and
criminal liabilities for white collar crimes. Title 1 contains provisions of the Public Company
Accounting Oversight board.
Some of the major provisions of the Act are :
(i) It requires public companies to evaluate and disclose the functioning of internal controls and
independent auditors have to agree to such disclosure.
(ii) Financial reports are to be certified by the Chief Financial Officer and Chief Executive
Officer.
(iii) Auditor independence , and outrightly prohibits any non audit work which can be carried out
by an independent auditor.
(iv) Prohibits personal loans to directors of the companies
(v) Accelerated reporting of insider trading
(vi) It also requires public companies to have an indepedent audit committee to oversee the
relationship between auditor and the company
(vii) Enhanced criminal and civil liabilities for any violations.

1. The folding of the polypeptide chain as a result of interactions betweent he side chains of
amino acids that lie in different regions of the primary sequence
2. Regular arrangement of amino acids within localized regions of the polypeptide
3. The interactions between different polypeptide chains in protiens composed of more than one
polypeptide
4. Polypeptide chain coils around itself, with the CO group of the peptide bond forming a
hydrogen bond with the NH group of a peptide bond located four residues downstream in the
linear
polypeptide chian.
5. Polypeptides form protiens upon proper folding, the three-dimensional state of the chian - this
is due to the constituent amino acids, so the shapes of protiens are determined by their amino
acid sequences
6. Two or more parts of a polypeptide chain that lie side by side with hydrogen bonds between
them; can be oriented either parallel or antiparallel to each other
7. These are the building blocks that execute the tasks directed by the information encoded in
genes. Their functions include: forming structural componenets of the cell, transportring and
storing small molecules, transmitting info between cells, providing defense against infection, and
to function as enzymes.
8. These are nonpolar molecules that consist of long chains of hydrocarbons. Their functions
include: a form of energy storage, major components of membranes, and important roles in
signaling as steriod hormones and as messenger molecules.
9. Can form hydrogen bonds with water molecules. Can form hydrogen bonds with other polar
molecules. Can interact with positively or negatively charged ions
10. These are inorganic ions that are involved in a number of cell processes such as: co-enzymes,
signaling messengers, and buffer systems.
11. These are the principle information molecules of the cell. Their functions include: making up
genetic material, to transfer info from nubleus to cytoplasm, catalyzing reactions, and serving as
template for protien synthesis.
12. These can be either simple or complex sugars. Their functions include: major source of
nutrients, starting material for other cell constituents, when conjugated to proteins they serve as
markers to target protiens to different cell locations.

Microprocessor An alarm system is to have 4 different devices, ea.pdf
Microprocessor An alarm system is to have 4 different devices, each with its sensor. One of the
sensors is to have interrupt address 83. Show and explain how that address is created using
switches and how the INTA signal is used to enable a tri-state buffer/driver to place the address
on the data lines.
Solution
Sometimes in digital electronic circuits we need to isolate logic gates from each other or have
them drive or switch higher than normal loads, such as relays, solenoids and lamps without the
need for inversion. One type of single input logic gate that allows us to do just that is called the
Digital Buffer.
Unlike the single input, single output inverter or NOT gate such as the TTL 7404 which inverts
or complements its input signal on the output, the “Buffer” performs no inversion or decision
making capabilities (like logic gates with two or more inputs) but instead produces an output
which exactly matches that of its input. In other words, a digital buffer does nothing as its output
state equals its input state.
Then digital buffers can be regarded as Idempotent gates applying Boole’s Idempotent Law
because when an input passes through this device its value is not changed. So the digital buffer is
a “non-inverting” device and will therefore give us the Boolean expression of: Q = A..
List three branches of the United States government and write a sent.pdf
List three branches of the United States government and write a sentence for each that describes
its function
Solution
The three separate branches of government: the legislative, the executive and the judicial.
Legislative Branch
The legislative branch is made up of the two houses of Congress—the Senate and the House of
Representatives. The most important duty of the legislative branch is to make laws. Laws are
written, discussed and voted on in Congress.
Executive Branch
The President is the head of the executive branch, which makes laws official. The President is
elected by the entire country and serves a four-year term. The President approves and carries out
laws passed by the legislative branch. He appoints or removes cabinet members and officials. He
negotiates treaties, and acts as head of state and commander in chief of the armed forces.
The executive branch also includes the Vice President and other officials, such as members of
the cabinet. The cabinet is made up of the heads of the 15 major departments of the government.
The cabinet gives advice to the President about important matters.
Judicial Branch
The judicial branch oversees the court system of the U.S. Through court cases, the judicial
branch explains the meaning of the Constitution and laws passed by Congress. The Supreme
Court is the head of the judicial branch. Unlike a criminal court, the Supreme Court rules
whether something is constitutional or unconstitutional—whether or not it is permitted under the
Constitution..
John is 5 years old and was diagnosed with cystic fibrosis following.pdf
John is 5 years old and was diagnosed with cystic fibrosis following intestinal obstruction after
birth. He has frequent infections despite respiratory therapy. Answer the following question
regarding Cystic Fibrosis.
1)John’s parents would like to have another child. What is the probability that the child will have
cystic fibrosis?
2)Describe the basic pathophysiology of cystic fibrosis and the effects in the body.
3)What are the effects on airflow of mucus obstruction in the lungs?
4)Why does John have frequent infections?
5)Why does John have fluid-electrolyte imbalances particularly when experiencing a high fever?
Solution
1) Since Cystic Fibrosis is an autosomal recessive disease, the chances of its occurrence are 1 in
four births. John\'s first child is having Cystic Fibrosis, still, the chance is 25% for the next child
to have the disease. The child may or may not have cystic fibrosis.
2) In cystic fibrosis, there is a mutation in the CFTR gene and different mutation in the gene
cause different protein formation which results in mild or severe disease. The gene is responsible
for the formation of a protein that anchors on the outer walls of the exocrine glands including
lungs, pancreas and sweat glands. The encoded protein creates a channel which is responsible for
the movement of halogens from inside and outside of the body. the nonfunctioning of the protein
results in the blockage of the channels of the affected organs and causes infection and
remodeling of the lungs. There is damage in the digestive system due to the accumulation of
digestive enzymes. Due to this, there are chances that the patient will acquire chronic infection
and proliferation of bacteria in the accumulated mucus in the lungs.
3) The airflow in the lungs gets affected in cystic fibrosis as there is deposition of mucus in the
small airways of the lungs. Since the mucus gets lined is dehydrated and is difficult to clear and
eventually obstructs the air pathway causing the destruction in alveoli and deposition of foreign
particles in the airways. This can lead to frequent chronic infections.
4) The reason behind the frequent infection of John is the mucus deposition in the air pathways
which leads to the proliferation of bacteria in the nutrient-rich mucus. These bacteria forms
biofilms inside which is difficult for the immune cells to penetrate and which makes the
condition severe.
5) This condition of John is due to the improper transfer of ions in the body due to the narrowing
of the channels. This gets severe as the body fights with the soaring body temperature as well as
the defect in the channels of ions transport..

In the previous years, 2004 and 2005 Nationwide paid out more than $1 Billion in claims due to
hurricanes. Given the limited information you have, what would have been your decision? Why
or why not? Please discuss
Solution
here what we need to discuss? Hurricanes and Tsunamis are the natural disasters, where one can
not stop them and can not blame others. the only thing here is we need to fight against the loss
and we should come together to save the effected people.
yes, in the last decade we faced many natural calamities like, Tsunamis, Earthquaques, Heavy
rains and floods and so on. there are some people who have taken insurance and there are some
who does not taken insurance. but irrespective of all these one should come forward to help them
and to support them to recover. we can not minimise the loss what happend, but we can support
them to recover faster.
individuals, organisations and nations also should come forward to save the effected people, it is
humanity and no one deny or object it..

If the sensitivity of the system is indeed low, can the data set still be used to describe the trends?
Solution
Yes, the sensitivity of a surveillance system data of epidemics can be used to describe
monitoring trends even if the sensitivity of the system is indeed low, as long as the sensitivity
remains constant. The alternations in sensitivity is mainly happen when increased awareness of a
health related disorder or any change in method of performing surveillance.
