a chemical intermediate in the production of polyurethane foams, elastomers, and coatings; paints; varnishes; wire enamels; sealants; adhesives; and binders. It is also used as a cross-linking agent in the manufacture of nylon polymers. Exposure Limits and Health…

called corrective feedback or knowledge of results. Students are shown the portions of a task that have been successfully achieved as well as the areas that need further growth. Feedback on the process relates to students’ strategies for error detection. For this reason, feedback at this level is more effective than at the task level for enhancing deeper learning (Hattie & Timperley, 2007, pp. 81-112). These two forms of feedback are in place to get the student to move from focusing on the…

Based on the information you researched, evaluate the level of responsibility of the company in terms of the effectiveness of the response to the security breach. Provide support for your rationale. The accounting field has over past few decades witnessed a number of changes mostly due to increased advancement in technology level. There has been an improvement from paper-based journal and ledgers to a new level of accounting system that is completely automated (The WritePass Journal, 2012). The…

Rather, simultaneously cracking gibberish codes until it reveals a somewhat revealing message. Innumerable codes have been introduced to the world, yet only a few have stood out, testing the brains of some of the greatest hackers in the world to the limit. A notable example of a common code includes the pigpen cipher, which exchanges letters for symbols, featured as fragments of a grid. An additional example is the Caesar cipher,…

avoiding such attacks such as Intrusion Detection System (IDS) which is the most popular method of defense [29]. A defense federation is used in [29] for guarding against such attacks. Under this technique each cloud is loaded with separate IDS. The different intrusion detection systems work on the basis of information that is exchange between these systems. In case a specific cloud is under attack, the cooperative IDS alert all other components in the system. Trustworthiness of a cloud is…

Both firewalls and intrusion detection systems are used to monitor network traffic and implement network security policies. Research these technologies and determine how they are similar and how they differ. Are both needed? Explain your answer in a short paper. Firewall From a definition standpoint, a firewall is a hardware or software used in a networked environment to block unauthorized access by individuals while permitting authorized communications to and from the user. The firewall is…

Security Onion intrusion detection system will be selected, installed, and evaluated. A trial deployment of the intrusion detection system will be attempted in a restricted environment, then a simulated attack will be carried out, and the results analysed. Security Onion is an IDS tool that is used to monitor network security, and log management. It contains other tools like sguil, snort, Bro, Suriacata, and OSSEC amongst others. The main functions of Security Onion are capturing packets,…

A murderer is someone who is narcissistic, often mentally ill and selfish. They have no compassion and don’t feel anything most of the time. That’s definitely the case for Larry Bittaker and Roy Norris also known as the “Toolbox Killers” as well as Ian Brady and Myra Hindley also known as the “Moors Murderers.” Lawrence “Larry” Bittaker was born in Pittsburgh, PA and was adopted as a baby. Because of his adopted fathers job, he was forced to move from place to place before they finally settled…

drug addiction (EMCDDA). Cocaine and its metabolites can be detected in hair, urine, saliva and blood1. It can be also be detected in surface water, waste water treatment plants2 and in banknotes3. Different methods have been reported for cocaine detection; enzyme immunoassay3, 4, 5, 6 , gas chromatography (GC) and liquid chromatography (LC), capillary electrophoresis (CE), immunoassay, thermal desorption tandem mass spectrometry (TD-MS2) and ion-mobility spectrometry (IMS)3.…

peak areas. The limit of detection and limit of quantification of the instrument were calculated 0.02 and 0.06 μg/ml, respectively. The accuracy of the method validation…
