Hazard and Operability Analysis of an Ethylene Oxide Production Plant

The purpose of this work was to evaluate potential hazards and failures as part of the design and economic analysis for a chemical plant that would produce 150,000 tons of ethylene oxide per year. The Hazard and Operability (HAZOP) method of analysis was used to accomplish this goal. This method of hazard analysis involves brainstorming potential errors in a system by examining each element of each process unit in full detail. This project was focused on the reactor unit because the reactor has several important parameters that could fail, resulting in safety issues within the system. Input for this analysis was received from the other members of the process team: Justin Brown, Alyssa Matarazzo, and Kyle Tynan as well as faculty mentors Dr. Thomas Stanford and Dr. Vincent Van Brunt. Through this analysis, many areas of concern for plant safety were found such as the ratio of hydrocarbon to oxygen causing an explosion hazard in the reactor, and the buildup of pressure in the reactor causing equipment failure. Additionally, safety precautions have been suggested such as adding a pressure relief system to the reactor, implementing controls on process parameters such as temperature and pressure, and writing emergency shutdown procedures in the case of system malfunction. These safety precautions are important for protecting the employees of the plant and the surrounding community

The Friends of Hospice Thrift Store Marketing Plan

The Friends of Hospice Thrift Shop is preparing to launch an expansion of their business by obtaining more square footage at their current location to develop a “boutique” atmosphere, with the goal of attracting more customers. Although the rental cost is quoted as being greater than the current cost of renting the space presently in use, it is hoped that the additional space will pay for itself by bringing in greater revenue. Furthermore, a trial-based reduced rate will be proposed in order to determine the success level of this expansion project, and whether profits will cover expenses to justify a permanent increase in the shop’s dimensions. It is believed that this growth will prove worthwhile because more people are frequenting thrift shops seeking low cost options due the status of the economy. At the Hospice Thrift Store, customers can find inexpensive, quality goods. This is especially appealing to low income clients, like senior citizens, who quantitatively comprise the majority of the current target market. The up-and-coming new generation of teenagers and twenty-something’s is another market worthy of targeting because of the products they seek. The new boutique can be marketed to this new demographic, who seek the new trend of vintage style. The shop relies on some newspaper advertising as well as word-of-mouth from loyal, satisfied customers. The ‘Heart in a Shopping Cart’ logo inspires everyone to feel welcome in the shop’s atmosphere and feel good about their purchase, knowing the funds go to a good cause. The primary marketing objective is to achieve steady profit growth over the course of the sixth month trial period. Upon presenting this marketing plan in May 2014, concepts have been implemented over the long term. Key words: The Friends of Hospice Thrift Shop, Marketing Plan, retail, marketing objective, consignment shop, advertising, boutique

Cryptococcal Neuroradiological Lesions Correlate with Severity during Cryptococcal Meningoencephalitis in HIV-Positive Patients in the HAART Era

Cryptococcal meningoencephalitis has an overall global mortality rate of 20% in AIDS patients despite antifungals. There is a need for additional means of precise assessment of disease severity. We thus studied the radiological brain images available from 62 HIV-positive patients with cryptococcocal meningoencephalitis to analyse the brain lesions associated with cryptococcosis in relationship with disease severity, and the respective diagnostic contribution of magnetic resonance (MR) versus computed tomography (CT)

Borders I: Baja California

While visiting California Western School of Law in San Diego, where there is so much tension over the US/Mexico border, Patricia saw an art installation around the idea of borders jointly produced by the arts communities in San Diego and Tijuana. This quilt expresses the irony of constructing a fence between people - in this case continuing out to sea so that one wonders if the fish observe the lines. Quilt Detail: In memory of Esequiel Hernandez, Jr., a Texas teenager killed while tending goats near his home at the border, 1997. Quotation from Robert Frost\u27s poem Mending Wall: He only says Good fences make good neighbors. Before I built a wall I\u27d ask to know What I was walling in or walling out.https://digitalcommons.law.umaryland.edu/quilts/1017/thumbnail.jp
