PICOT question for Infection Control nurse clinical Work

1.In the past few years, your hospital has installed antibacterial foam dispensers on all the nursing units. You’ve had nurses asking you if the foam is just as effective as washing their hands with water and soap.

Open to check your PICO analysis of the scenario.

P: hospital nurses
I: using antibacterial foam
C: hand washing with soap and water
O: decreased bacteria count

In hospital nurses, does antibacterial foam decrease bacteria count on hands as much as hand washing with soap and water?

Project-3 (200 Pts) Computing Frequency & Prob. Of words Due Date: 3/12

Your complete project is not in a SINGLE xxxxxp3.java file, where xxxxx is the
first 5 characters of your last name and p3 is the project number.
It does not read input from System.in. i.e. command prompt.
Using package or any java utilities such as arraylist, LinkedList ,map, queue….i.e.
the whole code should be written by yourself as explained in class.
Given a *.txt document as input, write an efficient java program xxxxxp3.java to compute
frequency and probability of words in input using binary search tree(bst).
FYI:The output of this project is the input for next project to compute optimal biniary
search tree (obst) for words in any document.
Please write your Last name, First name and Student ID at the beginning of your java file
as well as at the beginning of the output. Your main method should be as follow:
public static void main(String args[]) throws exception{
xxxxxp3 obstinput = new xxxxxp3 ();
// xxxxx is the first 5 characters of your last name
System.out.print(“ntProgram to compute frequency and probability of words in
+ *.txt file.nPrepared by Last: , First:
+ ntStudent ID: Date: “);
// read input and build bst tree
obstinput.buildbstree();
// Print created bst in ascending order in a user friendly manner.
obstinput.printbstree();
}// end main method
To compile at the command prompt: javac xxxxxp3.java
To execute at the command prompt: java xxxxxp3 < any data file

For the following input

public and static void main string and new is the first chars and of your last name void try
scanner public static and void main string new is the first void chars of your void last
name try scanner public and static void main string new is the
The output should be
Input sorted by words, Total number of words = 48
Word Freq Prob
1- and 5 0.1042
2- chars 2 0.0417
3- first 2 0.0417
4- is 3 0.0625
5- last 2 0.0417

National framework for protecting critical infrastructure

Look at a real-world scenario and how the Department of Homeland Security (DHS) plays into it. In the scenario, the United States will be hit by a large-scale, coordinated cyber attack organized by China. These attacks debilitate the functioning of government agencies, parts of the critical infrastructure, and commercial ventures. The IT infrastructure of several agencies are paralyzed, the electric grid in most of the country is shut down, telephone traffic is seriously limited and satellite communications are down (limiting the Department of Defense’s [DOD’s] ability to communicate with commands overseas). International commerce and financial institutions are also severely hit. Please explain how DHS should handle this situation.

You must do the following:

1) Create a new thread. As indicated above, please explain how DHS should handle the situation described in the preceding paragraph.

Physics Energy

  1. If a population grows at the rate of 2% per year, in how many years will it approximately double?
  2. A big coal digger is moving an average of 23 tons of subbituminous Wyoming coal per minute into dump trucks. This coal has an energy content of 10,750 Btu/lb. How many gigawatts (GW) of power does this flow of coal represent?
  3. Suppose 2 large tankers containing liquefied natural gas (LNG) leave a gas export terminal every day. The methane is stored in liquid form in the tankers, at -260°F, in a volume 600 times smaller than would be needed in gas form, at STP (Standard Temperature and Pressure: 0°C temperature, 1 atm pressure). Suppose the average tanker at this port carries an amount of LNG equivalent to 118 million cubic meters of methane at STP. The energy content of methane is 38.5 MJ per cubic meter at STP. How many gigawatts (GW) of power does this daily flow of natural gas through the port represent?
  4. Consider a heat engine that has an exhaust temperature of 227 degrees Celsius. If the Carnot efficiency for this engine is 34%, what is its high temperature (in degrees Celsius)?
  5. Suppose a region has been sprinkled with Cs-137 by a nuclear accident, and the radiation from the soil from Cs-137 is 581 times the normal background radiation. After waiting for 120.7 years, what would be the ratio of this Cs-137 radiation to the normal background radiation? The half-life of Cs-137 is 30.17 years.
  6. Suppose a bicyclist is burning 49 Calories per mile traveled. Convert this rate of energy use to a number of “miles per gallon of gasoline equivalent,” by comparing this to the caloric content of one U.S. gallon of gasoline (132 MJ). (This is similar to the number of miles per gallon of, e.g., olive oil, because gasoline and vegetable oils have similar mass density (~0.72 g/cc vs. ~0.9 g/cc) and caloric density (~11.6 Cal/g vs. ~9 Cal/g).)
