Food security refers to the availability of food and one’s access to it. A household is considered food-secure when its occupants do not live in hunger or fear of starvation. According to the World Resources Institute‚ global per capita food production has been increasing substantially for the past several decades.[1] In 2006‚ MSNBC reported that globally‚ the number of people who are overweight has surpassed the number who are undernourished - the world had more than one billion people who were

Information security Information Security Attributes: or qualities‚ i.e.‚ Confidentiality‚ Integrity and Availability (CIA). Information Systems are composed in three main portions‚ hardware‚ software and communications with the purpose to help identify and apply information security industry standards‚ as mechanisms of protection and prevention‚ at three levels or layers: physical‚ personal and organizational. Essentially‚ procedures or policies are implemented to tell people (administrators

For my project‚ I had to create my own acid-base indicator and find out what happens when it is placed in an acidic solution (vinegar) and a basic solution (dissolved baking soda). I chose my indicator to be a fruit because fruits can be very effective at determining how acidic or basic a substance is. My fruit was a blueberry‚ but I couldn’t use raw blueberries because it’s not going to give me the best results. I had to make blueberry juice. I did this by placing several blueberries in a blender

CYBER-PHYSICAL SYSTEMS SECURITY FOR THE SMART GRID A. C´ardenas ‚ R. Moreno‚ “Cyber-Physical Systems security for the Smart Grid‚” CPS Workshop 2011. The authors focus on giving a brief overview of why traditional security mechanisms for power systems are inadequate and the need for CPS security. They briefly describe the functional areas of the grid: State estimation-need for SE‚ mathematically modeling it‚ testing bad measurements. Constructing the network topology based

Acid-Base Titration Background Information A titration is a controlled addition of one substance into another substance. In an acid-base titration‚ the experimenter will add a base of known concentration to an acid of unknown concentration (or vice-versa). The goal of the titration is usually to use the substance of known concentration to determine the concentration of the other substance. In order to run a titration‚ the following materials are needed: • A buret filled with the base (or acid) of

SECURITY OF WIRELESS COMMUNICATIONS Introduction Wireless devices‚ like all technologies that provide external access to corporate networks‚ present security challenges. With wireless standards and practices still rapidly evolving‚ it is important to understand the strengths and limitations of available technologies in order to implement a secure solution. Extending current security policies to encompass wireless devices requires an understanding of the security features of both wireless devices

Security Brutality Before the year 2000 airports were smooth transportation services. People could enter an airport and basically walk right on to their planes without being hassled by airport security. Air travel safety precautions changed dramatically after the September 11‚ 2001‚ terrorist attacks that targeted passenger planes in the United States. After many years of upping security in airports‚ the Transportation Security Administration knew that metal detectors weren’t enough to pick up

Computer Security Many commercial software packages are designed with computer security features that control who can access the computer. These types of access controls use a process called identification and authentication. Identification verifies that the user is a valid user‚ and authentication verifies that the user is who he or she claims to be. Three common methods of authentication are remembered information‚ possessed objects‚ and biometric devices. With remembered information‚ a

Lab Report: Acid and Base Indicator Lab The title of my lab report is “Acid and Base Indicator Lab” this lab is testing what household solutions area bases depending on what color they changed. You have to use the pH balance scale to determine Acid‚ Base‚ and Neutral. On this lab we used 7 different solutions to determine if it’s either base‚ acid‚ and neutral. These are ammonia‚ vinegar; drain cleaner‚ soft drink‚ baking soda‚ detergent‚ and lemon juice are the solutions that are going to be
