An employee is assigned to one department and a department may have m.pdf
An employee is assigned to one department and a department may have many employees
assigned to it. An employee may work on many projects and each project an employee works on
the date and hours worked is recorded. A project is assigned a name, budget, start date and
completion date. An employee can be assigned to a project on more than one occasion.
Solution
Arelation is in 2nd normal form if all non key attributes are fully functionally dependent on
primary key.
A relation is in 3rd normal if it is in 2nd normal form and no non key attribute is transitively
dependent on the primary key.
The relation
(EmployNo,EmpName,DepartNo.DepartName,projectNo,Projectname,ProjectStartDate,ProjectE
ndDate,Budget,EmpDateWorked,EmpHoursWorked)
is not in 2nd normal form and thus not in 3rd normal form
functional dependencies
EmployNo --------> EmpName
DepartNo --------> DepartName
ProjectNo ---------> ProjectName
ProjectNo ---------> ProjectStartDate
ProjectNo ---------> ProjectEndDate
ProjectNo ---------> Budget
ProjectNo ---------> EmpDateWorked
ProjectNo ---------> EmpHoursWorked
based on these functional dependencies we can make three tables
EMPLOYEE (EmployNo,EmpName)
DEPARTMENT(DepartNo,DepartName)
PROJECT(ProjectNo,ProjectName,ProjectStartDate,ProjectEndDate,Budget,EmpDateWorked,E
mpHoursWorked)
There is no transitive dependency in these tables and all non key attributes are fully functionally
dependent on primary keys(underlined ). So the tables are in 3rd Normal Form..

Whats the Schema Table Column Row Attribute Entity Pri.pdf
What\'s the Schema ? Table ? Column ? Row ? Attribute ? Entity ? Primary Key ? Foreign Key ?
Solution
Schema is a subdatabase(database is divided into various subdatabases) which contains database
objects .The database objects are tables,views etc
Table:A table consists of various rows and columns.Data is arranged in rows and columns.
Column:column in the database contains data which are of same type.
Row :table contains various rows and columns.The rows in table is called as tuples .
Attribute :The database table contains various attributes.It represents database fields
Entity:Entity is a single object .We are going to staore the date regarding that object which is
called as entity
Primary key:
Primary key is a unique value in the table by using which we can uniquely idenfy the rows or
records in the table.
Primary key is NOT NULL+UNIQUE
It is constraint which maintains the data integrity of the table in the database.
That means if we specified a column with primary key constraint.Then in that column we must
have to provide the value(Not to leave empty) and also that value must be unique.
If we want to uniquely identify particular records in the table we have to use these primary
keys.Primary keys must not be NULL and should be UNIQUE.
Ex:Suppose we are storing the employee information in the employee table.
The employee table has fields like : employeeId,employeeName,Salary
Here No two employees have same employeeID\'s .It will be unique.
If we want to get the information of the particular employee we can use his employeeID inorder
to uniquely identify.The value with which we can uniquely identify the records in a table is
called PrimaryKey.here We can say employeeId is a primary key.
Foreign Key:
A foreign key is a primary of one table but it appears like a field in another table.Here both the
two tables are in relation with each other .
Suppose there is a student table which contains studentId as primary key.
There is a course table which contains courseID as primary key.
There is a studentCourse table which contains studentId and courseId as fields.But studentId is
the primary of student table and courseId is primary key of course table.But those two primary
keys are acting as fields as in studentCouse table.
here Field (studentID) of studentCouse table is linked with studentId field of Student table
and field (courseId) of studentCouse table is linked with courseId field of course table
So we may call studentId,courseId are foreign keys of studentscourse table.
Foreign keys - Contain one or more columns whose values match a primary or alternate key in
some other table..

Solution
The groups that produce sporangia on leaves are :-
a. Lycophyta
c. Monilophyta
Explanation: Lycophyta is one of the four phyla of seedless plants having vascular or conducting
tissue. Unlike higher plants, lycophytes do not produce seeds. They carry sporophylls- the leaves
that bears the spores. On the other hand phylum Bryophyta includes mosses whose reproduction
is carried out with the help of sporophyte. In mosses the sporophyte is a capsular structure
growing at the end of the stalk called the seta. Again, Monilophyta includes ferns. They differ
from lycophtes by having true leaves. they also carry sporophyll for reproduction. Hepatophyta
includes liverworts while Anthecerophyta includes hornworts. They both come under phlum
Bryophyta and reproduction is carried out through sporophyte..
What is tax research What is the purpose of conducting tax research.pdf
What is tax research? What is the purpose of conducting tax research? Are results of tax research
conclusive
Solution
Tax research is undertaken to answer taxation questions. The tax research process includes the 1)
identification of pertinent issues, 2) determination of proper authorities, 3) evaluation of the
appropriateness of these authorities, and 4) application of these authorities to specific facts. The
tax research process is similar to that of traditional legal research. The researcher must find
authority, evaluate the usefulness of that authority, and apply the results of the research to a
specific situation. Tax research is simply the study of the sources/nature of federal tax law, and
it\'s explanations and interpretations. Possible sources for tax research are the IRS and the Tax
Court. These results are not always conclusive. \"explanations and intrepretations\" are, by their
nature, subjective and open to change. The change could be a higher court ruling on a matter ,or
a change in the basic law itself.
Tax research is important because taxes are important. They have priority demands on cash flow
and substantial impacts on the bottom line. Entrepreneurs and managers in today\'s rapidly
changing, increasingly global environment must consider the tax implications of contemplated
transactions, since tax planning works much better before rather than after a proposed
transaction. “Tax research is important because once key issues are spotted, decision makers
must judge the specific affected rules and rulings. No one knows all the rules in any area,
particularly in multiple Jurisdictions--e.g., Federal, state, and local; and foreign--and for various
kinds of taxes--e.g., income, value added, and payroll” (Karayan, 2003)..

Question I need help with c++ Simple Classes Assigment. i get this .pdf
Question: I need help with c++ Simple Classes Assigment. i get this code working but i have to
change my setID from numbers in loop{1,2,3,4,5} to setID to *char which it have to start with
lastName, then lastName, then year of birth.
c++ Simple Classes Assignment
In this assignment, you will write a struct plus two simple classes and then write a program
that uses them all. The first class is a Date class. You are given code for this at the end of this
assignment, but you must make some modifications. The other is a Patient class; you are given
the class definition and you must write the implementation. The program will keep track of
patients at a walk-in clinic. For each patient, the clinic keeps a record of all procedures done.
This is a good candidate for a class, but to simplify the assignment, we will make a procedure
into a struct. We will assume that the clinic has assigned all care providers (doctors, nurses, lab
technicians) with IDs and each procedure (“office visit”, “physical exam”, “blood sample taken”,
etc.) also has an ID. Each patient will also have an ID, which is formed by the last name
concatenated with the first name and the year of birth. All other IDs (care providers, procedures)
will be just integers.
When the user runs the program at the start of the day, it first tries to read in from a binary file
called CurrentPatients.dat. It will contain the number of patients(in binary format) followed by
binary copies of records for the patients at the clinic . This information should be read and stored
in an array of Patient objects. There will be a separate array, initially empty at the start of the
program that will store patient records for all patients who are currently checked in at the clinic.
It then asks the user to enter the current date and reads it in. It should then presents the user with
a simple menu: the letter N to check in a new patient, R for checking in a returning patient, O to
check out a patient, I to print out information on a particular patient, P to print the list of patients
who have checked in, but not yet checked out, and Q for quitting the program.
The following tasks are done when the appropriate letter is chosen.
N: The new patient’s first name, last name, and birthdate are asked for and entered. The new
patient ID will be the last name concatenated with the first name and the year of birth. (Example:
SmithJohn1998) The primary doctor’s ID is also entered. The new patient object is placed in
both arrays: one keeping all patients, and one keeping the patients who checked in today.
R: The returning patient’s ID is asked for, and the array holding all patients is searched for the
patient object. If found, a copy of the patient object is placed in the array for all currently
checked in patients. If not found, the user is returned to the main menu after asking them to
either try R again, making sure the correct ID was entered, or choose N to enter the patient as a
new patient.
O: Using the patient’s ID.

Do antidepressants help? A researcher studied the effect of an antidepressant on depression. He
randomly assigned subjects with moderate levels of depression to two groups. One group
received the antidepressant and the other a placebo. Subjects were blinded with respect to the
treatment they received. After four weeks, the researcher interviewed all subjects and rated the
change in their symptoms based on the comments of subjects during the interview. Critics said
that the results were suspect because the ratings were not blind. Explain what this means and
how lack of blindness could bias the reported results.

Much of the heat that drives convection in the mantlea. Is generat.pdf
Much of the heat that drives convection in the mantle
a. Is generated by friction between the core and mantle as Earth rotates
b. Is transferred to the mantle from the white hot core by conduction
c. Remains from the original formation of Earth from the sun
d. Is produced by radioactive decay or uranium and thorium
Solution
Answer: (d)
Mantle convection is the slow creeping motion of Earth\'s solid silicate mantle caused by
convection currents carrying heat from the interior of the Earth to the surface.
Much of the heat that drives convection in the mantle is due to radiogenic heat from the fission
of the radioisotopes uranium, thorium, and especially potassium found naturally in the earth\'s
core and mantle..

Solution
Darwin proposed \'descent with modification\' by observing the beaks of finches in Galapagos
Islands. Although all of them belonged to the same species, they vary in shape of their beaks
according to the habitat they live. The best adapted to the habitat would survive long, reproduce
and pass the genes to next generation. All these species are divergent species share a common
ancestor
The correct answer is Divergent species share a common ancestor..

Check all that are characteristics of cardiac muscle. Cells are long and cylindrical. Cells are
short and branching. Cells have multiple nuclei at the periphery of the Cells have one or two
nuclei in the center of the. They are composed of thick and thin filaments. This functional
contractile unit is the sarcomere.
Solution
Cardiac muscle fibres are essentially long and cylindrical cells.
Cardiac myocytes are narrower and much shorter than skeletal muscle cells which are normally
spindle-shaped.
The cells that constitute cardiac muscle, called cardiomyocytes or myocardiocytes, mostly
contain contain one nucleus but many mitochondria sometimes two to four nuclei also exist.
Cardiac muscle has cross striations formed by rotating segments of thick and thin protein
filaments.
The SARCOMERE is the contractile unit of the myocardial cell.
It contains myosin and actin filaments as well as troponin and tropomysin. Shortening of
sarcomeres causes contraction by the sliding filament..

Operation Blue Star - Saka Neela Tara
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Question I need help with c++ Simple Classes Assigment. i get this .pdf
Question: I need help with c++ Simple Classes Assigment. i get this code working but i have to
change my setID from numbers in loop{1,2,3,4,5} to setID to *char which it have to start with
lastName, then lastName, then year of birth.
c++ Simple Classes Assignment
In this assignment, you will write a struct plus two simple classes and then write a program
that uses them all. The first class is a Date class. You are given code for this at the end of this
assignment, but you must make some modifications. The other is a Patient class; you are given
the class definition and you must write the implementation. The program will keep track of
patients at a walk-in clinic. For each patient, the clinic keeps a record of all procedures done.
This is a good candidate for a class, but to simplify the assignment, we will make a procedure
into a struct. We will assume that the clinic has assigned all care providers (doctors, nurses, lab
technicians) with IDs and each procedure (“office visit”, “physical exam”, “blood sample taken”,
etc.) also has an ID. Each patient will also have an ID, which is formed by the last name
concatenated with the first name and the year of birth. All other IDs (care providers, procedures)
will be just integers.
When the user runs the program at the start of the day, it first tries to read in from a binary file
called CurrentPatients.dat. It will contain the number of patients(in binary format) followed by
binary copies of records for the patients at the clinic . This information should be read and stored
in an array of Patient objects. There will be a separate array, initially empty at the start of the
program that will store patient records for all patients who are currently checked in at the clinic.
It then asks the user to enter the current date and reads it in. It should then presents the user with
a simple menu: the letter N to check in a new patient, R for checking in a returning patient, O to
check out a patient, I to print out information on a particular patient, P to print the list of patients
who have checked in, but not yet checked out, and Q for quitting the program.
The following tasks are done when the appropriate letter is chosen.
N: The new patient’s first name, last name, and birthdate are asked for and entered. The new
patient ID will be the last name concatenated with the first name and the year of birth. (Example:
SmithJohn1998) The primary doctor’s ID is also entered. The new patient object is placed in
both arrays: one keeping all patients, and one keeping the patients who checked in today.
R: The returning patient’s ID is asked for, and the array holding all patients is searched for the
patient object. If found, a copy of the patient object is placed in the array for all currently
checked in patients. If not found, the user is returned to the main menu after asking them to
either try R again, making sure the correct ID was entered, or choose N to enter the patient as a
new patient.
O: Using the patient’s ID.
Do antidepressants help A researcher studied the effect of an an.pdf
Do antidepressants help? A researcher studied the effect of an antidepressant on depression. He
randomly assigned subjects with moderate levels of depression to two groups. One group
received the antidepressant and the other a placebo. Subjects were blinded with respect to the
treatment they received. After four weeks, the researcher interviewed all subjects and rated the
change in their symptoms based on the comments of subjects during the interview. Critics said
that the results were suspect because the ratings were not blind. Explain what this means and
how lack of blindness could bias the reported results.

Much of the heat that drives convection in the mantlea. Is generat.pdf
Much of the heat that drives convection in the mantle
a. Is generated by friction between the core and mantle as Earth rotates
b. Is transferred to the mantle from the white hot core by conduction
c. Remains from the original formation of Earth from the sun
d. Is produced by radioactive decay or uranium and thorium
Solution
Answer: (d)
Mantle convection is the slow creeping motion of Earth\'s solid silicate mantle caused by
convection currents carrying heat from the interior of the Earth to the surface.
Much of the heat that drives convection in the mantle is due to radiogenic heat from the fission
of the radioisotopes uranium, thorium, and especially potassium found naturally in the earth\'s
core and mantle..

In explaining what we now call evolution, Darwin often used the phrase “descent with
modification.” Fundamental to this idea is that-Natural selection is the primary mechanism of
evolution.-We have knowledge of the genetic basis of evolutionary change.-Earth has been
shaped by slow-acting forces that are still at work today.-Divergent species share a common
ancestor.-Species are immutable.In explaining what we now call evolution, Darwin often used
the phrase “descent with modification.” Fundamental to this idea is that-Natural selection is the
primary mechanism of evolution.-We have knowledge of the genetic basis of evolutionary
change.-Earth has been shaped by slow-acting forces that are still at work today.-Divergent
species share a common ancestor.-Species are immutable.
Solution
Darwin proposed \'descent with modification\' by observing the beaks of finches in Galapagos
Islands. Although all of them belonged to the same species, they vary in shape of their beaks
according to the habitat they live. The best adapted to the habitat would survive long, reproduce
and pass the genes to next generation. All these species are divergent species share a common
ancestor
The correct answer is Divergent species share a common ancestor..

Check all that are characteristics of cardiac muscle. Cells are .pdf
Check all that are characteristics of cardiac muscle. Cells are long and cylindrical. Cells are
short and branching. Cells have multiple nuclei at the periphery of the Cells have one or two
nuclei in the center of the. They are composed of thick and thin filaments. This functional
contractile unit is the sarcomere.
Solution
Cardiac muscle fibres are essentially long and cylindrical cells.
Cardiac myocytes are narrower and much shorter than skeletal muscle cells which are normally
spindle-shaped.
The cells that constitute cardiac muscle, called cardiomyocytes or myocardiocytes, mostly
contain contain one nucleus but many mitochondria sometimes two to four nuclei also exist.
Cardiac muscle has cross striations formed by rotating segments of thick and thin protein
filaments.
The SARCOMERE is the contractile unit of the myocardial cell.
It contains myosin and actin filaments as well as troponin and tropomysin. Shortening of
sarcomeres causes contraction by the sliding filament..

Goldstein and brown were lucky. If they had used the JD allele to compare with wild type rather
than an allele that results in complete loss of the LDLr protein, the graph of _____ would look
much different.LDL binding
Solution
Answer is LDL import.
NPVY domain recruits clathrin and other proteins responsible for the endocytosis of LDL,
therefore this mutation inhibits LDL internalization. \"JD\" mutant results from a single point
mutation in the NPVY domain.

A Strategic Approach: GenAI in Education
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.
