I need help making these adjustments to my \"class Persons_Information\" In your Person class: Add a constant field to store the current year (review the Week 4 Lesson if you aren\'t sure how to create a constant) : Assign a value to the current year field when it is declared (do not add it to the constructors). Add fields to store a person\'s age in years and how many years they have been with the college: Do not add mutator or accessor methods for these fields. Set the visibility modifier to private for these fields. Modify both constructors to set default values for both fields. Add processing actions: Add a method to calculate a person\'s age in years only. Add a method to calculate how long a person has been in college in years only. Make both methods private. Do not take any input or display any output in these methods. Modify the toString() method: Call the method to calculate the person\'s age. Call the method to calculate how long the person has been in college. Add the person\'s age to the String. Add the person\'s time in college to the String. Add output messages for each field so that the user knows what they are looking at. Format the string using the new line escape sequence \ so that each field and it\'s message is on a separate line. *** This is what I have so far. 48 class Persons_Information 49 { 50 private String personName; 51 private String currentAdress; 52 private String permanentAdress; 53 private int idNumber; 54 private String birthDate; 55 private int personAge; 56 private int entryYear; 57 private int totalYears; 58 59 public Persons_Information() { 60 personName = \"\"; 61 currentAdress = \"\"; 62 permanentAdress = \"\"; 63 idNumber = 0; 64 birthDate = \"\"; 65 personAge = 0; 66 entryYear = 0; 67 totalYears = 0; 68 } 69 70 public Persons_Information (int atIdNumber) { 71 idNumber = atIdNumber; 72 personName = \"\"; 73 currentAdress = \"\"; 74 permanentAdress = \"\"; 75 birthDate = \"\"; 76 personAge = 0; 77 entryYear = 0; 78 totalYears = 0; 79 } 80 81 //intput 82 83 public void setPersonName(String personName) { 84 this.personName = personName; 85 } 86 87 public void setCurrentAdress(String currentAdress) { 88 this.currentAdress = currentAdress; 89 } 90 91 92 public void setpermanentAdress(String permanentAdress) { 93 this.permanentAdress = permanentAdress; 94 } 95 96 public void setIdNumber(int id) { 97 idNumber = id; 98 } 99 100 public void setBirthDate(String birthDate) { 101 this.birthDate = birthDate; 102 } 103 104 public void setPersonAge(int pa) { 105 personAge = pa; 106 } 107 108 public void setEntryYear(int ey) { 109 entryYear = ey; 110 } 111 112 public void setTotalYears(int ty) { 113 totalYears = ty; 114 } 115 116 //output 117 118 public String getPersonName() { 119 return personName; 120 } 121 122 public String getCurrentAdress() { 123 return currentAdress; 124 } 125 126 public String getPermanentAdress() { 127 return permanentAdress; 128 } 129 130 public int getIdNumber() { 131 return idNumber; 132 }.

Add a method to calculate how long a person has been in college in years only.
Make both methods private.
Do not take any input or display any output in these methods.
Modify the toString() method:
Call the method to calculate the person\'s age.
Call the method to calculate how long the person has been in college.
Add the person\'s age to the String.
Add the person\'s time in college to the String.

In your Person classChange the visibility of all fields from priv.pdf
In your Person class:
Change the visibility of all fields from private to protected.
Change the visibility of the methods to calculate age and time in college from private to
protected.
Create a Student class:
Inherit from the Person class.
Add fields to store:
Students major.
Students GPA.
Do not add any other fields.
Create a default constructor (it should not have any parameters) for the Student class
Create mutator and accessor methods for the major and GPA fields.
Override the toString() method from the Person class:
Include all of the same information found in the Person class toString() method.
Make sure you call the methods to calculate the persons age in years and their time in college in
years (Note that these methods are in the Person class but, because you inherit from the Person
class, you will be able to call them from the Student class).
Add an opening message stating the person is a Student.
Add the Students major to the string.
Add the Students GPA to the string.
Add output messages for each field so that the user knows what they are looking at.
Format the string using the new line escape sequence \ so that each field and it\'s message is on a
separate line.
In your test class:
Create a Student object.
Ask the user for all of the information for the student:
ID Number
Name
Current Address
Permanent Address
Year of Birth
Year entered college
Major
GPA
Call the toString() method to display all of the information.

So Far I have these two classes but I need help with my persontest c.pdf
So Far I have these two classes but I need help with my persontest class:
The next step is to add method calls for the accessor methods after each input:
//Reading and updating values
System.out.print(\"\ Enter Person Name: \");
person1.setPersonName(sc.nextLine());
System.out.println(\"You entered: \" + person1.getPersonName());
Call the accessor function each time you ask for input, after capturing that input. Then repeat for
a second Person, only this time call the constructor that takes the student id as a parameter.

Repeat Programming Project 2 in Chapter 5. This time, add the following four constructor
methods: one for each instance variable, one with two parameters for the two instance variables,
and a default constructor. Be sure that each constructor sets all the instance variables. write a
driver program to test each of the methods, including each of the four constructors and at least
one true or false case for each of the test method.

define a class name Employee whose objects are records for employee..pdf
define a class name Employee whose objects are records for employee. Derive this class from the
class person given in the listing 8.1. An employee record inherits an employee\'s name from the
class Person. In addition, an employee record contains an annual salary represented as a single
value of type double, a hire date that gives the year hired as a single value of type int, and an
identification number that is a value of type String. Give your class a reasonable complement of
constructors, accessor methods, and mutator methods, as well as an equals method. Write a
program to fully test your class definition

In your Person classAdd a constant field to store the current yea.pdf
In your Person class:
Add a constant field to store the current year (review the Week 4 Lesson if you aren\'t sure how
to create a constant) :
Assign a value to the current year field when it is declared (do not add it to the constructors).
Add fields to store a person\'s age in years and how many years they have been with the college:
Do not add mutator or accessor methods for these fields.
Set the visibility modifier to private for these fields.
Modify both constructors to set default values for both fields.
Add processing actions:
Add a method to calculate a person\'s age in years only.
Add a method to calculate how long a person has been in college in years only.
Make both methods private.
Do not take any input or display any output in these methods.
Modify the toString() method:
Call the method to calculate the person\'s age.
Call the method to calculate how long the person has been in college.
Add the person\'s age to the String.
Add the person\'s time in college to the String.
Add output messages for each field so that the user knows what they are looking at.
Format the string using the new line escape sequence \ so that each field and it\'s message is on a
separate line.

In your Person classChange the visibility of all fields from priv.pdf
In your Person class:
Change the visibility of all fields from private to protected.
Change the visibility of the methods to calculate age and time in college from private to
protected.
Create a Student class:
Inherit from the Person class.
Add fields to store:
Students major.
Students GPA.
Do not add any other fields.
Create a default constructor (it should not have any parameters) for the Student class
Create mutator and accessor methods for the major and GPA fields.
Override the toString() method from the Person class:
Include all of the same information found in the Person class toString() method.
Make sure you call the methods to calculate the persons age in years and their time in college in
years (Note that these methods are in the Person class but, because you inherit from the Person
class, you will be able to call them from the Student class).
Add an opening message stating the person is a Student.
Add the Students major to the string.
Add the Students GPA to the string.
Add output messages for each field so that the user knows what they are looking at.
Format the string using the new line escape sequence \ so that each field and it\'s message is on a
separate line.
In your test class:
Create a Student object.
Ask the user for all of the information for the student:
ID Number
Name
Current Address
Permanent Address
Year of Birth
Year entered college
Major
GPA
Call the toString() method to display all of the information.

So Far I have these two classes but I need help with my persontest c.pdf
So Far I have these two classes but I need help with my persontest class:
The next step is to add method calls for the accessor methods after each input:
//Reading and updating values
System.out.print(\"\ Enter Person Name: \");
person1.setPersonName(sc.nextLine());
System.out.println(\"You entered: \" + person1.getPersonName());
Call the accessor function each time you ask for input, after capturing that input. Then repeat for
a second Person, only this time call the constructor that takes the student id as a parameter.

define a class name Employee whose objects are records for employee..pdf
define a class name Employee whose objects are records for employee. Derive this class from the
class person given in the listing 8.1. An employee record inherits an employee\'s name from the
class Person. In addition, an employee record contains an annual salary represented as a single
value of type double, a hire date that gives the year hired as a single value of type int, and an
identification number that is a value of type String. Give your class a reasonable complement of
constructors, accessor methods, and mutator methods, as well as an equals method. Write a

Hello. Im working on an assignment that tests inheritance and comp.pdf
Hello. I\'m working on an assignment that tests inheritance and composition but I\'m still
learning so I\'m having trouble. I will provide the code I have so far.. The class i need help
creating is going to be a patient class. \"Design the class Patient, inherited from the class Person,
with additional data members to store a patient’s ID, age, date of birth, attending physician, the
date when the patient was admitted in the hospital, and the date when the patient was discharged
from the hospital. Therefore, the Patient IS-A Person and HAS-A Doctor and several Dates (i.e.,
date of birth, admit date, discharge date). You should use the class Date to store the date of birth,
admit date, discharge date, and the class Doctor to store the attending physician. Add appropriate
constructors and methods to initialize, access, and manipulate data members.\" Thank you for the
help! I\'m still learning so if you don\'t mind leaving documentation comments so I can follow
the code, it would be a huge help. Thanks again.

Java questionI am having issues returning the score sort in numeri.pdf
Java question
I am having issues returning the score sort in numerical order for more than 2 entries. I had to
develop an enhancement which allowed the application to sort the list by score. The easiest
solution is probably to create a second student class (perhaps called StudentScore) that
implements the IComparable interface to sort by score rather than by name
StudentSortApp
import java.util.*;
public class StudentSortApp
{
public static void main(String[] args)
{
System.out.println(\"Welcome to the Student Scores Application.\"+\"\ \");
Scanner sc = new Scanner(System.in);
System.out.print(\"Enter number of students to enter: \");
int numberofStudents = sc.nextInt();
//arrays storing student name and score
Student[] students = new Student[numberofStudents];
StudentScore [] studentScores = new StudentScore [numberofStudents];
int t = 0;
for (int i = 0; i < numberofStudents; i++)
{
System.out.println(\"\");
String studentLastName = Validator.lastName(sc, \"Student \" + (i+1) + \" Last name: \");
String studentFirstName = Validator.lastName(sc, \"Student \" + (i+1) + \" First name: \");
int studentScore = Validator.validScore(sc, \"Student \" + (i+1) + \" score : \");
students [t] = new Student(studentFirstName, studentLastName , studentScore);
studentScores [t] = new StudentScore(studentFirstName, studentLastName , studentScore);
t = t + 1;
}
//output
System.out.println(\"\");
System.out.println(\"Last Name Sort\");
Arrays.sort(students, 0, numberofStudents);
for(Student i: students)
System.out.println(i.getlastName()+\", \"+i.getfirstName()+\": \"+i.getScore());
System.out.println();
System.out.println(\"Score Sort\");
Arrays.sort(studentScores, 0, numberofStudents);
for(StudentScore i: studentScores)
System.out.println(i.getlastName()+\", \"+i.getfirstName()+\": \"+i.getScore());
}
}

Overview You are tasked with writing a program called Social Security.pdf
Overview You are tasked with writing a program called Social Security that prompts the user to
enter the data (name and date-ofbirth)for a collection of people. The program will then process
this collection (array) of People (objects we create in another file) to determine who qualifies for
Social Security benefits. Specifications For our Social Security program we will need two java
files 1. Person java The person class which stores the data for a specific individual 2.
SocialSecurity.java (The driver) Details for these two class files appear below. Person ava UML
diagram name: String birthdate: LocalDate Person0 Person (newName: String, month: int, day:
int, year: int) NetName newName: String) void getName(): String set BirthDate month int, day:
int, year int) void get BirthDate 0 LocalDate toString(): String calculate Age(myBirth
LocalDate) int Person ava method description Two constructors 1. A Default constructor that
creates a Person whose name and birthdate are set to null. 2. A parameterized constructor that
accepts a String representation of the name, and three integers corresponding to the month, day,
and year in which the person was born. Setters and getters for the two instance variables. A
toString0 method that prints the person in the form dob

i need help to edit the two methods below so that i can have them wo.pdf
I have to make a program for my C class and im stuck on the part where i have to calculate the
variance with elements from my array. This is exactly what im suppose to do:
Reset the sum variable to 0
Using another for loop (which needs its own loop variable), run through all valid elements of the
array, starting from index 0. Inside the loop:
Use the sum variable to accumulate the numerator of the variance formula shown on page 1.
After the end of this loop, compute the variance by dividing the new sum by the
dataElementsToProcess parameter.
this is the entire function
bool GenerateStatistics(FILE *fp2, double myArray[], int dataElementsToProcess)
{
if (fp2 == NULL && myArray == NULL && dataElementsToProcess < 1)
{
return false;
}
else
{
int i = 0,o = 0;
int sum = 0, sum1 = 0;
double maxValue = 0;
double minValue = DBL_MAX;
double mean, variance, stdDeviation;
for (int i = 0; i < 600; i++)
{
sum += myArray[i];
if (myArray[i] > maxValue)
{
maxValue = myArray[i];
}
if (myArray[i] < minValue)
{
minValue = myArray[i]; }
}
mean = sum / dataElementsToProcess;
sum = 0;
for (int o = 0; o < 600; o++)
{
sum += myArray[o];
}
variance = sqrt(pow((sum - mean), 2) / (dataElementsToProcess));
stdDeviation = sqrt(variance);
fprintf(fp2, \"Reaction Rate Statistics:\ \ \");
fprintf(fp2, \"Number of experiments = %d\ \", dataElementsToProcess);
fprintf(fp2, \"Minimum rate\\t\\t= %f\ \", minValue);
fprintf(fp2, \"Maximum rate\\t\\t= %f\ \", maxValue);
fprintf(fp2, \"Arithmetic mean\\t\\t= %f\ \", mean);
fprintf(fp2, \"Variance\\t\\t= %f\ \", variance);
fprintf(fp2, \"Standard deviation\\t= %f\ \ \ \", stdDeviation);
}
return true;
}
Solution
Here in the function you have
average - mean
Noofelements - dataElementsTo Process
Variance formula is
V = summation over i=1 to n ((xi - mean )*(xi - mean))
So perform like this using a for loop over my_array
double V=0.0
for(int i=0;i<600;i++)
{
V=V+pow((my_Array[i]-mean),2)
}
Now calculate standard deviation using sqrt of variance
sd=0.0
sd=sqrt(V).

Goal
In this assignment students will practice inheritance and polymorphism in C++.Objectives
Class Programming: Given an object-based entity with specific functionality, students should be able to create an equivalent C++ class to represent it.
Problem:
1. Add to class patientType the date when the patient was admitted in the hospital, and the date when the patient was discharged from the hospital (Use the class Date class you wrote in the prelab) to store admit date, discharge date. Modify constructors and add member functions to initialize access, and manipulate the new added data members.
2. In main(), create a vector of pointers to type TeamPerson. Fill it up with at least three objects. One of TeamPerson, one of doctorType and one of patientType.
3. Print all the data of the three objects of the vector. Make sure each object is printed according to its print function.

I need help for my next project due next tuesday can you help me in .pdf
I need help for my next project due next tuesday can you help me in writing this program and
can you make it a simple program easy as possible.
note here are the parameters of the program in bold:
Design a class named Employee. The class should keep the following information in fields:
• Employee name
• Employee number in the format XXX–L, where each X is a digit within the range 0–9
and the L is a letter within the range A–M.
• Hire date
Write one or more constructors and the appropriate accessor and mutator methods for the class.
Next, write a class named Production Worker that extends the Employee class. The
Production Worker class should have fields to hold the following information:
• Shift (an integer)
• Hourly pay rate (a double)
The workday is divided into two shifts: day and night. The shift field will be an integer value
representing the shift that the employee works. The day shift is shift 1 and the night shift is
shift 2. Write one or more constructors and the appropriate accessor and mutator methods for
the class. Demonstrate the classes by writing a program that uses a Production Worker object.
Each class needs a no-arg constructor and a constructor that initializes all fields with data (The
Production Worker class constructor should receive data for the Employee class fields as well)
Create a method within the Employee and Production Worker classes called display Info.
(display Info accepts no arguments and returns void) To display the data for each constructor, the
demonstration class will call the subclass display Info method and it will call the superclass
display Info method. User input is not required for the demonstration class.

Okay So basically what you have to create a C Program for an application. This should be called

Are silenced genes associated with high or low levels of DNA methyla.pdf
Are silenced genes associated with high or low levels of DNA methylation?
Solution
1.Genes are silenced by methylation(adding methyl groups). Gene silencing is the process of
turning off genes,so that it will not produce proteins through translation process.
2. Gene silencing is done by adding methyl groups to the genes. So that gene is inactive.
So we conclude that silenced genes associated with high methylation. Because when gene is
methylated only then silencing of gene occurs..

Hello. Im working on an assignment that tests inheritance and comp.pdf
Hello. I\'m working on an assignment that tests inheritance and composition but I\'m still
learning so I\'m having trouble. I will provide the code I have so far.. The class i need help
creating is going to be a patient class. \"Design the class Patient, inherited from the class Person,
with additional data members to store a patient’s ID, age, date of birth, attending physician, the
date when the patient was admitted in the hospital, and the date when the patient was discharged
from the hospital. Therefore, the Patient IS-A Person and HAS-A Doctor and several Dates (i.e.,
date of birth, admit date, discharge date). You should use the class Date to store the date of birth,
admit date, discharge date, and the class Doctor to store the attending physician. Add appropriate
constructors and methods to initialize, access, and manipulate data members.\" Thank you for the
help! I\'m still learning so if you don\'t mind leaving documentation comments so I can follow
the code, it would be a huge help. Thanks again.

Java questionI am having issues returning the score sort in numeri.pdf
Java question
I am having issues returning the score sort in numerical order for more than 2 entries. I had to
develop an enhancement which allowed the application to sort the list by score. The easiest
solution is probably to create a second student class (perhaps called StudentScore) that
implements the IComparable interface to sort by score rather than by name
StudentSortApp
import java.util.*;
public class StudentSortApp
{
public static void main(String[] args)
{
System.out.println(\"Welcome to the Student Scores Application.\"+\"\ \");
Scanner sc = new Scanner(System.in);

int numberofStudents = sc.nextInt();
//arrays storing student name and score
Student[] students = new Student[numberofStudents];
StudentScore [] studentScores = new StudentScore [numberofStudents];
int t = 0;
for (int i = 0; i < numberofStudents; i++)
{
System.out.println(\"\");
String studentLastName = Validator.lastName(sc, \"Student \" + (i+1) + \" Last name: \");
String studentFirstName = Validator.lastName(sc, \"Student \" + (i+1) + \" First name: \");
int studentScore = Validator.validScore(sc, \"Student \" + (i+1) + \" score : \");
students [t] = new Student(studentFirstName, studentLastName , studentScore);
studentScores [t] = new StudentScore(studentFirstName, studentLastName , studentScore);
t = t + 1;
}
//output
System.out.println(\"\");
System.out.println(\"Last Name Sort\");

Arrays.sort(studentScores, 0, numberofStudents);
for(StudentScore i: studentScores)

variance with elements from my array. This is exactly what im suppose to do:
Reset the sum variable to 0
Using another for loop (which needs its own loop variable), run through all valid elements of the
array, starting from index 0. Inside the loop:
Use the sum variable to accumulate the numerator of the variance formula shown on page 1.
After the end of this loop, compute the variance by dividing the new sum by the
dataElementsToProcess parameter.
this is the entire function
bool GenerateStatistics(FILE *fp2, double myArray[], int dataElementsToProcess)
{
if (fp2 == NULL && myArray == NULL && dataElementsToProcess < 1)
{
return false;
}
else
{
int i = 0,o = 0;
int sum = 0, sum1 = 0;
double maxValue = 0;
double minValue = DBL_MAX;
double mean, variance, stdDeviation;
for (int i = 0; i < 600; i++)
{
sum += myArray[i];
if (myArray[i] > maxValue)
{
maxValue = myArray[i];
}
if (myArray[i] < minValue)
{
minValue = myArray[i]; }
}
mean = sum / dataElementsToProcess;
sum = 0;
for (int o = 0; o < 600; o++)
{
sum += myArray[o];
}
variance = sqrt(pow((sum - mean), 2) / (dataElementsToProcess));
stdDeviation = sqrt(variance);
fprintf(fp2, \"Reaction Rate Statistics:\ \ \");
fprintf(fp2, \"Number of experiments = %d\ \", dataElementsToProcess);
fprintf(fp2, \"Minimum rate\\t\\t= %f\ \", minValue);
fprintf(fp2, \"Maximum rate\\t\\t= %f\ \", maxValue);
fprintf(fp2, \"Arithmetic mean\\t\\t= %f\ \", mean);
fprintf(fp2, \"Variance\\t\\t= %f\ \", variance);
fprintf(fp2, \"Standard deviation\\t= %f\ \ \ \", stdDeviation);
}
return true;
}
Solution
Here in the function you have
average - mean
Noofelements - dataElementsTo Process
Variance formula is
V = summation over i=1 to n ((xi - mean )*(xi - mean))
So perform like this using a for loop over my_array
double V=0.0
for(int i=0;i<600;i++)
{
V=V+pow((my_Array[i]-mean),2)
}
Now calculate standard deviation using sqrt of variance
sd=0.0
sd=sqrt(V).

I need help for my next project due next tuesday can you help me in .pdf
I need help for my next project due next tuesday can you help me in writing this program and
can you make it a simple program easy as possible.
note here are the parameters of the program in bold:
Design a class named Employee. The class should keep the following information in fields:
• Employee name
• Employee number in the format XXX–L, where each X is a digit within the range 0–9
and the L is a letter within the range A–M.
• Hire date
Write one or more constructors and the appropriate accessor and mutator methods for the class.
Next, write a class named Production Worker that extends the Employee class. The
Production Worker class should have fields to hold the following information:
• Shift (an integer)
• Hourly pay rate (a double)
The workday is divided into two shifts: day and night. The shift field will be an integer value
representing the shift that the employee works. The day shift is shift 1 and the night shift is
shift 2. Write one or more constructors and the appropriate accessor and mutator methods for
the class. Demonstrate the classes by writing a program that uses a Production Worker object.
Each class needs a no-arg constructor and a constructor that initializes all fields with data (The
Production Worker class constructor should receive data for the Employee class fields as well)
Create a method within the Employee and Production Worker classes called display Info.
(display Info accepts no arguments and returns void) To display the data for each constructor, the
demonstration class will call the subclass display Info method and it will call the superclass
display Info method. User input is not required for the demonstration class.

Are silenced genes associated with high or low levels of DNA methyla.pdf
Are silenced genes associated with high or low levels of DNA methylation?
Solution
1.Genes are silenced by methylation(adding methyl groups). Gene silencing is the process of
turning off genes,so that it will not produce proteins through translation process.
2. Gene silencing is done by adding methyl groups to the genes. So that gene is inactive.
So we conclude that silenced genes associated with high methylation. Because when gene is
methylated only then silencing of gene occurs..
A south facing window is 2.1 m high and 4.2 m long. A horizontal diff.pdf
A south facing window is 2.1 m high and 4.2 m long. A horizontal diffuse reflector is places in
front of the window and hinged at the bottom edge of the window. Radiation data for an hour are
I = 1.61 MJ/m^2, I_d = 0.33 MJ/m^2, I_b = 1.28 MJ/m^2 and R_b = 2.31. If the (diffuse)
reflectance of the reflector is 0.85, what will be the total irradiation per unit area on the window?
Solution
we know that total radiation=incident radiation=beamed radiation.
Write an extended summary (They say”) of Sheryl Sandbergs Lean.pdf

If You Weren\'t Afraid.\" In your last paragraph, make a claim about Sandberg\'s essay(\"I
Say\"). Use this template to frame the \"I Say\" paragraph:
My own experience yields a point that is similar/different/both similar and different. (INSERT
A BRIEF PERSONAL STORY HERE THAT IS RELEVANT. YOUR STORY CAN BE
BASED ON YOUR WORK EXPERIENCE, YOUR SCHOOL EXPERIENCE, OR AN
EXPERIENCE YOU HAVE HEARD ABOUT. You can use other evidence, but I want you to
focus on the summary here, so there is no need to invest tons of time researching and reading.
) What I take away from my own experience/this example/this research is.....
Solution
Although this question is also not related with Economics.
But I would like to share my real experience here-I had only one brother ( we are 4 sisters and 1
brother ) .He was very pempared from the childhood. My father was a doctor ,he loved his five
kids equally, but my mother and two elder sisters always pampered him.He could not get proper
education even after his marrige he was not able to take proper decisions.But he was very good
and loveble persone. He loved me very much .In 2013 Feb-Doctore declared that he was in the
last stage of cencer.Although he was feeling some problem last six months but he ignored
them.He never told me about his problems.He always pretented that he was very happy and
healthy.But when he was not able to tolerate he told me and showed me all reports.that time he
was weeping bitterly .I took him in many hospitals but was not able to save his life.It was the
greatest lose of life..

With a blow count of 14 the density of the soil is Select one 15e bit.pdf
With a blow count of 14 the density of the soil is Select one 15e bitery dense. SC. Medium
Solution
solution-
if blow count is between 4 to 10 then the soil is loose, if blow count is between 10 to 30 then it
will be medium dense and if it is between 30 and 50 then it will be dense and greater than 50
means soil is very dense.
Here no of blow count is 14 it means soil is medium dense.Hence option c is correct.

Solution
The Greek economic crisis is the result of multiple reasons, like slow down of GDP growth rate,
higher government deficit and government debt. But the primary reason is excessive government
spending that was not matched by adequate tax reveneue. This resulted in highe government
(fiscal) deficit which was funded by higher borrowing. Higher government debt led to the
soverign debt crisis in Greece..

There are several things fundamentally wrong in this illustration. Po.pdf
There are several things fundamentally wrong in this illustration. Point out two of them. Point
them out, describe why they are wrong, and what they were supposed to be. You can look up
anything (especially the lecture 12). size or shape of illustration do not apply (e.g. RNA primer
looks like only a few bases, but that is okay, or Helicase is triangular, but that is fine, too).
Solution
1: Since lagging strand is discontinuously synthesized in form of Okazaki fragments, RNA
primer serve to form primer for synthesis of each of these fragments. So, RNA primer should be
located adjacent to the DNA pol at lagging strand.
2: DNA pol alpha serve to form RNA/DNA primers for lagging strand synthesis. These primers
are then exptended by DNA pol delta. At lagging strand, only DNA pol alpha is shown..

Suppose that 14 of people are left handed. If you pick two people a.pdf
Suppose that 14% of people are left handed. If you pick two people at random, what is the
probability that
(1) they both are left handed? (round your answer to 2 decimal places)
(2) only one of them is left handed? (round your answer to 2 decimal places)
Solution
1)
P(both left handed) = 0.14*0.14 = 0.0196 [ANSWER]
********************
b)
There are two ways to do this, that is, the first one is left handed and the scond is right handed, or
the other way around.
Hence, we mutliply the product of probabilities by 2:
P(one is left handed) = 2*0.14*(1-0.14) = 0.2408 [ANSWER].

Solution
(1)
Ionic bonds result when complete transfer of valence electron(s) between atoms
Example: NaCl, KCl
Covalent bonds result when valence electrons are shared between atoms.
Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared
between two atoms: Example: HCl,
Nonpolar covalent bonds are a type of chemical bond where two atoms share a pair of electrons
with each other. Example: CCl3, H2
A hydrogen bond is the attractive force between the hydrogen attached to an electronegative
atom of one molecule and an electronegative atom of a different molecule
Example: Hydrogen bonding occurs between electronegative oxygen of water with hydrogens of
other water molecules..
NEED HELP ON C HOMEWORKIntroduction Programmers for a Better Tomo.pdf
NEED HELP ON C HOMEWORK
Introduction: Programmers for a Better Tomorrow
Programmers for a Better Tomorrow is an organization dedicated to helping charities, medical
societies, and scholarship organizations manage various tasks so that they can focus on making
the world a better place! They have asked you and your classmates to help them develop some
new programs to benefit their organizations.
Problem: Food Bank Management (foodbank.c)
Programmers for a Better Tomorrow is now in partnership with a local Food Bank which
distributes food items to people in need. People come in to a Food Bank and make their
donations, and others might come in to make a request for any food item they want.
A Food Bank Management Program is used to keep track of the stock the Food Bank has (i.e.,
the donations), keep a record of requests that come in, fulfilling requests and printing the status
report which consists of the amount of stock present in the food bank and the requests that are
not yet fulfilled.
The program will require you to make at least one array. You may choose to make multiple one-
dimensional arrays: one to serve as a Donations Table and one to serve as a Request Table. The
index of the array will represent the inventory type. The value in the array will represent the
amount present or needed of that type.
You may, instead, choose to combine these to two arrays into a single two-dimensional array.
There are 5 inventory types:
Protein
Dairy
Grains
Vegetables
Fruits
Your program should allow the user the following options:
Enter a Donation
Enter a Request
Fulfill Requests
Print status report
Exit
Option 1:
Ask the user for the inventory type and amount of the donation to be made. When the donation
has been added to the donations table, the program should notify the user by printing out
“Donation Added”.
Option 2:
Ask the user for the inventory type and amount of the request to be made. When the request has
been added to the requests table, the program should notify the user by printing out “Request
Added”.
Option 3:
Check each type of inventory in the Request Table.
For each item that has a value in the request table, check to see if there is inventory of the same
type in the donations table.
If there are no donations of that type, print “ requests cannot be fulfilled.” Replace with the
correct inventory type (Dairy, Fruit, etc.).
If there is some inventory in the donations table, but not enough to process all requests, print “
requests will be partially fulfilled”. Reduce both the donation and request amounts based on how
much of the request was able to be fulfilled. Replace with the correct inventory type (Dairy,
Fruit, etc.).
If there is enough inventory to fulfill the request, print “type x> requests will be fulfilled.”
Reduce the appropriate amount from the Donations Table and remove the amount from the
Request Table. Replace with the correct inventory type (Dairy, Fruit, etc.).
Option 4:
Print both tables, indicating which is for donations a.

Our understanding of genetic inheritance and the function of DNA i.pdf
Our understanding of genetic inheritance and the function of DNA in producing the
characteristics of the individual have been developing for more than 150 years. Consider our
current state of knowledge. Link genetic characteristics to DNA structure. Explain how DNA
through the process of protein synthesis is responsible for the ultimate expression of the
characteristics in the organism. Describe how interference in protein synthesis can result in
disruption of cellular and bodily processes? How does the significance of one class of proteins,
the enzymes, relate to the importance of proper nutrition throughout life?

disruption of cellular and bodily processes? How does the significance of one class of proteins,

Solution
1.The gene encoding the production of protein is transcribed into the gene language required for
the next stage which is RNA. The RNA is then transcribed into protein for protection or the
function assigned. This is a simple illustration of how DNA can regulate expression of
characteristics.There are 2 parts to this process:translation and transcription.The gene for a
particular trait undergoes a process called transcription. This is a process in which the language
of the body\'s make-up is transcribed from one cell language to another (DNA to RNA) which
the body will recognize in order to carry out the next process. The next process is the translation
of the information from RNA to the actual product, which is the protein. Specific proteins play
specific roles so the body synthesizes the specific protein for the specific job at the specific time.
2.Errors in protein synthesis disrupt cellular fitness, cause disease phenotypes, and shape gene
and genome evolution.errors in protein synthesis reduce organism fitness: disruption of
translational fidelity with common antibiotics such as streptomycin and kanamycin kills bacteria;
cells with impaired translational proofreading ability display altered morphologies and suffer
severe fitness defects, as do cells with elevated rates of transcription errors in an essential gene;
defects in translational fidelity and in protein folding cause disease phenotypes in mouse
models.Synthesis and degradation of non-functional proteins may also be costly without being
obviously harmful. Ribosomal throughput dedicated to a polypeptide that will ultimately fail to
function represents an opportunity cost, particularly for fast-growing organisms. Expression of

2024.06.01 Introducing a competency framework for languag learning materials ...
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
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.

I need help making these adjustments to my class Persons_Informati.pdf
- 1. I need help making these adjustments to my "class Persons_Information" In your Person class: Add a constant field to store the current year (review the Week 4 Lesson if you aren't sure how to create a constant) : Assign a value to the current year field when it is declared (do not add it to the constructors). Add fields to store a person's age in years and how many years they have been with the college: Do not add mutator or accessor methods for these fields. Set the visibility modifier to private for these fields. Modify both constructors to set default values for both fields. Add processing actions: Add a method to calculate a person's age in years only. Add a method to calculate how long a person has been in college in years only. Make both methods private. Do not take any input or display any output in these methods. Modify the toString() method: Call the method to calculate the person's age. Call the method to calculate how long the person has been in college. Add the person's age to the String. Add the person's time in college to the String. Add output messages for each field so that the user knows what they are looking at. Format the string using the new line escape sequence so that each field and it's message is on a separate line. *** This is what I have so far. 48 class Persons_Information 49 { 50 private String personName; 51 private String currentAdress; 52 private String permanentAdress; 53 private int idNumber; 54 private String birthDate; 55 private int personAge; 56 private int entryYear; 57 private int totalYears; 58 59 public Persons_Information() {
