Laboratory Scenarios - Essay Example According to the National Institute for Occupational safety and Health (2006), anyone entering or using the lab has to have detailed knowledge of the dangers and risks involved, and the risks presented by each of the reagents in the laboratory. This knowledge is important in helping the lab users to indentify potential risks and take the appropriate measures to prevent these risks from occurring. Below is a detailed analysis of three laboratory situations that clearly do not follow the safety procedures and that put lab users at great danger. In Scenario 2, there are deliberate safety procedures that were overlooked. The student was working in the lab late night. This means that the lab might not be well lit and since it was late night, the student might have been fatigued thus placing the bottle wrongly at the counter making it to shutter and spill the contents. The student had no safety clothing or lab protective gear, making the contents to spill on her clothing. The bottle was wrongly used for unintended purpose, since it originally contained chloroform and the label canceled out. In addition, the student was cleaning the floor with bare hands without the use of gloves, which is a great health risk. She was cut in the process, and decided to ignore the first aid criteria by only applying a simple bandage. Moreover, she found it not necessary to alert others and especially reporting to the lab supervisors concerning the case. One of the relevant authorities that are concerned with such cases is the Clinical and Laboratory Standards Institute that sets and writes guidelines and safety procedures to be followed in the laboratory, as would be suited to the case above (Merrick et al, 2006). The body designs and outlines documents that contain quality clinical practices that have to be followed in such chemistry labs. This lab seems not to comply with any of the lab practices and guidelines and as Hampton (2011)

Telecommunications and Networking - Essay Example The imaginary Internet cloud of a corporate network environment is trustworthy for data transportation. Moreover, it is incorporated with advanced cloud generalization. In order to extend the cloud-computing concept, there are services along with network components consisting of routers, switches, application servers, and data servers. The components of the network are installed to operate at the back-end for providing advanced services that are proficient to develop web application (What is cloud computing?). Moreover, cloud computing consists of applications that are represented as a service on the web and the provision of hardware / software services provided by companies operating data centers. Likewise, the services provided over the Internet are referred as (Software as a Service) ‘SaaS’. Few sellers use the term (Infrastructure as a service) IaaS and (Platform as a service) PaaS ’in order to demonstrate their products and services. However, these terms are avoided and not accepted globally, due to variation (ARMBRUST, FOX et al. 2010). The Commerce Department’s National Institute of Standards and Technology (NIST) have illustrated some helpful definitions that focus on three concepts (Ryan, Loeffler 2010): Cloud infrastructure as a service ‘IaaS’ consists of provisioning elementary computing resources. Cloud software as a service ‘SaaS’ access software application that operates on a cloud infrastructure. Cloud platform as a service (PaaS) provides the accessibility to users for implementing and developing applications with programming language and tools supported by the providers. The core components of a cloud are consists of the data center hardware and software. When these resources are made available to the public, they are referred as public clouds and the service provided by the cloud is called as utility computing. Moreover, private clouds are only available to private organizations and are not accessible by public. Accordingly, cloud computing is the combination of ‘SaaS’ and utility computing (ARMBRUST, FOX et al. 2010). Furthermore, cloud computing is a successful contributor economically for cyber infrastructure as it â€Å"makes applications dramatically easier to develop and deploy, thus expanding the feasible scope of applications possible within budget and organizational constraints, and shifting the scientist’s and engineer’s effort away from information technology development and concentrating it on scientific and engineering research. Cyber infrastructure also increases efficiency, quality, and reliability by capturing commonalities among application needs, and facilitates the efficient sharing of equipment and services† (Vouk 2008)(Vouk 2008). Business Trends Information Technology organization has already invested millions since the 1990’s, to contribute in reshaping cloud computing. For instance, a popular slogan from Sun that was â€Å"Network is a computer† was recognized in 1980’s. Furthermore, salesforce.com, a ‘SaaS’ enabled website is providing services since 1999. Today, cloud computing represents a more innovative and productive approach, in order to provide online services along with online operating systems. Microsoft Azure provides an online operating
