Chemistry
A volume of 40.0 mL of aqueous potassium hydroxide (KOH) was titrated against
a standard solution of sulfuric acid (H2SO4). What was the molarity of the
solution if 19.2 mL of 1.50 M H2SO4 was needed? The equation is 2KOH
(aq)+H2SO4(aq)=K2SO4(aq0+2H2O(l)

Why is cryptology important in information security
Computer Network Security
Organizations use a wide variety of encryption technologies for various
purposes. A key aspect of security is using the correct and necessary levels
of encryption and hashing. The type of encryption and hashing needed varies by
the type of organization: government, military, healthcare, academic,
business, or financial. Address at least two of the following questions in
your response.
Why is cryptology important in information security?
What would be the implications of not using cryptographic technologies?
Why might vendors propose proprietary encryption methods? Why is this suspect?
What are the benefits of using encryption? What are the negatives or costs of
using encryption?

Explain what is the mole percent of butane in the mixture
Chemistry
A gas sample is known to be a mixture of ethane and butane. A bulb of 200.0
cm^3 capacity is filled with the gas to a pressure of 100.0 x 10^3 Pa at 20.0
degrees C. If the weight of the gas in the bulb is 0.3846 g, what is the mole
percent of butane in the mixture?

Computer Network Security
After reading your memo, your manager agrees that steps need to be taken to
get his team to think about security. He has asked you to help.
Create either a PowerPoint presentation, or a training manual, that will help
get the team to think about security. This training document should cover the
following key areas:
1. Explain common organizational security threats (avenues of attack).
2. Convince the team that a majority of security issues derive from personnel.
3. Explain the risks to the organization”s database environment.

Qualitative Research Designs
You have focused on the features and considerations of quantitative research
designs. However, quantitative designs are not appropriate for all research
questions. Perhaps you are concerned with how patients react when confronted
with negative test results, or you wish to study how views on a certain health
topic change over time. In each of these cases, the emphasis is more on
understanding the thinking and experiences of an individual or group than on
numerical measurements. For these types of questions, a qualitative or mixed
methods research design is the most appropriate.
For this Discussion, you focus on the different types of qualitative research
designs, when they are used, and why they are important.
To prepare:
Reflect on the comments made by Dr. Mauk in this week’s media presentation on
the value of qualitative research in nursing.
Locate the journal Qualitative Health Research in the Sage Premier database in
the Walden Library.
From this journal, select an article of interest to you that was published
within the last 3 years.
Review the information on different qualitative research designs in Chapter 20
of your course text.
Determine what qualitative research design was used in your selected article
and evaluate whether it was the best choice.
Consider ethical issues involved in the study and how the researchers
addressed them.
Think about how using a quantitative design would have affected the type of
data gathered.

Computer Network Security
Explores the use of a one-time pad version of the Vigenère cipher. In this
scheme, the key is a stream of random numbers between 0 and 26. For example,
if the key is 3 19 5…, then the first letter of plaintext is encrypted with
a shift of 3 letters, the second with a shift of 19 letters, the third with a
shift of 5 letters, and so on.
a. Encrypt the plaintext sendmoremoney with the key stream 9 0 1 7 23 15 21 14
11 11 2 8 9
b. Using the cipher text produced in part (a), find a key so that the cipher
text decrypts to the plaintext cashnotneeded.

Measures of crime
Select a crime and write a report addressing the following:
Summarize the statistics from the last two reporting years. Be sure to include
demographic information such as ethnicity, race, age, gender, marital status,
employment status, socioeconomic group, etc., and moderator variables related
to the crime.
Examine the reliability and validity of these statistics. Are they accurate?
Why or why not? Be sure to discuss how age, gender, race, ethnicity, and
socioeconomic level are related to offending and representation in the
criminal justice system.
Explain whether certain populations are overrepresented in the statistics. If
so, why?
Describe the shift in roman empire
Describe the shift in roman empire
First, describe the shift in the Roman Empire that created Byzantium in the
East and what would eventually become Europe in the West and explain the
impact of this political, religious, and social split on the art produced in
these regions in this era. Provide specific examples of particular works of
art or architecture to illustrate your points. Second, trace the subsequent
development of art in the East and the West from the Early through the High
and Late Middle Ages by citing specific works of art or architecture and
describing characteristic features these works exemplify. Be sure to include
the each of the following terms in your discussion:
