For each enzyme, there is a small range of pH within which it works optimally. Enzymes have&nbsp.active sites in their structures. The active site is the part of the enzyme that has the correct shape and the functional groups required to bind to the substrate (Dunford, 1999). Enzyme activity can be measured in any one of these two ways: observing the rate at which the substrate disappears during a reaction or measuring the rate at which the product is formed. Enzyme assays are used in such measurements.

Two methods have been developed for use in measuring the number of substrates or products in a chemical reaction: continuous and fixed-timed assays. Continuous essays make use of a spectrophotometer to measure the rates at which the substrate disappears and products form in real-time (Leskovac, 2003). To measure the peroxidase activity a change in the amount of product formed will be evaluated over time. For the breakdown of peroxide by peroxidase, the simplest molecule that can be measured is O2 gas, the product of the decomposition of peroxide.

To accomplish this the real volume of O2 gas produced is measured by the use of an indicator. For this experiment, an indicator (pyrogallol) that shows the presence of O2 gas will be used (Dunford, 2010). 2.50 cm3, 0.35 cm3, 0.10 cm3, and 0.35 cm3 of deionized water, buffer solution (at a pH of 6.0), hydrogen peroxide, and pyrogallol respectively were pipetted into two separate cuvettes labeled Cuvette 1 and Cuvette 2. The contents of the cuvettes were then mixed well using a small glass rod. The spectrophotometer was set to 420 nm after which Cuvette 1 was placed into it. 0.1 ml of the buffer solution was added to the cuvette and then stirred using a small glass rod.

The readings of the spectrophotometer were recorded every 10 seconds for 5 minutes. Cuvette 2 (blank) was placed into the spectrophotometer. 0.1 ml of&nbsp.the enzyme was added to it and stirred using a small glass rod. The readings of the spectrophotometer were recorded every 10 seconds for 5 minutes.&nbsp.

Hi, I am looking for someone to write an article on disseminating organizational it security Paper must be at least 2000 words. Please, no plagiarized work!

The position requires that they purchase different parts for the computer network. Also, training and supervising prospective IT employees fall under the senior administrator’s job description.&nbsp.(Northcutt, 2002)

Information technology system lapses and breaches of data security may disrupt the Company’s capacity to function in the customary course of operation by potentially triggering delays or termination of customer orders, blocking the manufacture of goods, or causing the unpremeditated disclosure of Company information.

Management has engaged in steps to address these concerns for its systems by executing important network security and in-house controls. (Conti, 2007)

Information system security breaches

Information system security is the practice of defending information from unauthorized access, use, disclosure, disruption, modification, perusal, inspection, recording, or destruction. It is a general term that can be used regardless of the form the data may take. Companies store vast amounts of information.

The Various state laws recurrences to notify people who could be affected by security breaches. Some of the most encountered security breaches at the company include Physical Security Breach, Electronic Security Breach, Data Capture Security Breach, Hackers breach, Carelessness breach, Underreach, and Secrets breach. User authentication policy is the most applied in the company&nbsp.(Conti, 2007)

User Authentication policies

Account policy

The Account policy section of the system administration terminal allows him/her to set up an accounting policy.

accounting unit policy ours the account-related policies like password and account lockout policies. Once you have come up with an accounting policy, you can allocate the policy to all the users. (Microsoft, 2003)

As a best practice, senior administrators of IT should create and maintain typical user accounts whenever possible. If there is more than one administrator in the company, there is a need to create a personalized account for each of the administrators. Consequently, when an action is believed to be more administrative performed, it is possible to trace to the individual.

Create a 2 pages page paper that discusses gender roles in families.

Mad MenThe show on the “Mad Men” is an interesting series that reflects on the societal changes in terms of gender roles and issues that concern the women today. These issues were neglected by the past generations of women and they saw them as normal. According to the different views in the article I would like to conquer with some of the views and opinions of the various writers who have expressed opinions about the value that the show portrays in the contemporary society. First ResponseAccording to the first respondent, the show is based on the past, the 1960(s).

During this time, there were different gender roles as women were viewed just as subordinates and not equal partners in the society. The series presents, through its characters a society that undermines the power of women. For instance, women are given tasks that are feminine in a way. In the whole series, the women are just secretaries that are working under their bosses who are males. There are also women who are homemakers .There is a scene where the sectaries discuss the contraceptive pills.

They take pills in order to continue sleeping with their bosses. This shows how men viewed women in the past. The series is a throwback. However, things have changed since that time. The current society is a totally different society, women have been empowered by the changes in time and societal beliefs. The women are voiceless in the whole series in that the males mistreat them and no one talks about it. For example, when Joan is raped by her fiancé, she never talks about it in the first place.

This is a violation of her rights. She is rendered voiceless in this scene. This typically describes how women were viewed back then.Second ResponseThe second respondent views the series as a reminder of how the situation was for women in the 1960(s). This is, in my view, appreciating change, because of that past we see women appreciating how much space they have in the contemporary society. The society of back in those days had so many stereotypes about the women and gender roles. On the other hand, it also presents two choices for the women today.

The two choices are detailed in two characters in the series. In the series, we have the characters of Betty and Peggy. Betty is the stylish wife while Peggy is that woman who is keen about her career and really works hard in her job. This show emphasizes the changes that have occurred at the work place as being of help to the women. The changes have given them space to perform, unlike in the past that there were a lot of stereotypes that hindered their performance at the work place.These two scenarios are of importance to the current generation.

They are presented with a chance to be either of the two. This move is positive in the fight for equality in the 21st century. However, most of the women today have had to choose the lifestyle of a Becky. They admire that life that is of less hard work and more of just being provided for. A few in the society have learnt to appreciate the women taking advantage of the empowerment that has since enabled them be major partners in various ways in the world issues.Referencehttp://www.forbes.

Complete 4 pages APA formatted article: Economic Characteristics of Steel Industry. Increasing population in many parts of the world especially in BRIC countries has also increased the requirement of steel based products such as new vehicles, appliances and building infrastructures. Government is the first force that plays two critical roles. First, local and international sustainable and environmental laws are put into effect to protect the environment from adverse effects of steel producing plants. Second, when the steel firms require protection, it inflicts tariffs and trade regulations plus tax breaks or subsidies. however this can be minimized by providing Free Trade Agreements. Steel industry is highly influenced by technology and fuel prices. Technology has not only improved the quality of steel products but also the continuously growing fuel prices force the steel producing companies to figure out and implement new, innovative, and cost-effective technology and practices. During the past few years, the mergers and acquisitions have not only enhanced the growth of steel industry but also made the industry more cost competitive where competition is primarily based on prices. Recycling of steel and scrap material is another critical driving force which plays an important part in the joint projects.
