    The primary purpose of this research was to collect the information necessary to one day develop an environmentally sound and economically feasible water conservation management plan for the Illinois Wesleyan University campus. Freshwater resources are steadily being depleted due to pollution and climate change, while demand for potable water continues to rise alongside an exponentially growing global population. Due to this reason, water conservation is becoming an ever-important practice for municipalities, institutions, and even individuals in pursuit of maintaining a sustainable freshwater supply. Reducing demand upon the water supply of a community remains the best practice for maintaining sustainable freshwater resources. For this reason, Illinois Wesleyan University is looking for ways to reduce its overall water demand. Through extensive archival research into water conservation strategies and the City of Bloomington water supply, in-depth interviews with key informants on Illinois Wesleyan’s campus, and identification of ‘model university water management plans’, this project aims to create a comprehensive report that lays the foundation for the development of Illinois Wesleyan University’s first water management plan

    Lecturepg. 72-78The application of oil-free-integrated motor-compressors has become increasingly popular in recent years. One of the significant features of this class of machinery is compactness, providing space-savings compared to traditional-oil-lubricated compressors with associated gearboxes and lubrication systems. The integration of a turbo separator with such a compressor has resulted in the creation of a new class of turbomachinery promising even greater system compactness. This new machine type provides further size reduction benefits through the elimination of large static separation vessels often required on traditional compressor trains. A compressor manufacturer has successfully developed a centrifugal compressor with integrated turbo separator from design, development, and prototype testing on a demonstration rig through to manufacture, testing, and shipment of a production unit. This paper focuses on the details and results of the testing performed at the manufacturer’s factory that confirmed the soundness and acceptability of the design. Rigorous testing of the demonstration rig has confirmed acceptable rotordynamic performance including stable operation over a wide range of operating pressures and liquid injection rates. The rotordynamic performance of this machinery type has been demonstrated to be virtually insensitive to liquid injection

This population has also rapidly increased their use of new social networking technologies (e.g. mobile camera/ video phones; Facebook and YouTube) and are said to be obsessed with identity, image and celebrity. This research project explored the ways in which new technologies are being used by a range of young people (and others, including marketers) in drinking practices and drinking cultures in Aotearoa/NZ. It also explored how these technologies impact on young adults’ behaviours and identities, and how this varies across young adults of diverse ethnicities (Maori [indigenous people of NZ], Pasifika [people descended from the Pacific Islands] and Pakeha [people of European descent]), social classes and genders. We collected data from a large and diverse sample of young adults aged 18-25 years employing novel and innovative methodologies across three data collection stages. In total 141 participants took part in 34 friendship focus group discussions (12 Pakeha, 12 Maori and 10 Pasifika groups) while 23 young adults showed and discussed their Facebook pages during an individual interview that involved screencapture software and video recordings. Popular online material regarding drinking alcohol was also collected (via groups, interviews, and web searches), providing a database of 487 links to relevant material (including websites, apps, and games). Critical and in-depth qualitative analyses across these multimodal datasets were undertaken. Key findings demonstrated that social technologies play a crucial role in young adults’ drinking cultures and processes of identity construction. Consuming alcohol to a point of intoxication was a commonplace leisure-time activity for most of the young adult participants, and social network technologies were fully integrated into their drinking cultures. Facebook was employed by all participants and was used before, during and following drinking episodes. Uploading and sharing photos on Facebook was particularly central to young people’s drinking cultures and the ongoing creation of their identities. This involved a great deal of Facebook ‘work’ to ensure appropriate identity displays such as tagging (the addition of explanatory or identifying labels) and untagging photos. Being visible online was crucial for many young adults, and they put significant amounts of time and energy into updating and maintaining Facebook pages, particularly with material regarding drinking practices and events. However this was not consistent across the sample, and our findings revealed nuanced and complex ways in which people from different ethnicities, genders and social classes engaged with drinking cultures and new technologies in different ways, reflecting their positioning within the social structure. Pakeha shared their drinking practices online with relatively little reflection, while Pasifika and Maori participants were more likely to discuss avoiding online displays of drinking and demonstrated greater reflexive self-surveillance. Females spoke of being more aware of normative expectations around gender than males, and described particular forms of online identity displays (e.g. moderated intake, controlled selfdetermination). Participants from upper socio-economic groups expressed less concern than others about both drinking and posting material online. Celebrity culture was actively engaged with, in part at least, as a means of expressing what it is to be a young adult in contemporary society, and reinforcing the need for young people to engage in their own everyday practices of ‘celebritising’ themselves through drinking cultures online. Alcohol companies employed social media to market their products to young people in sophisticated ways that meant the campaigns and actions were rarely perceived as marketing. Online alcohol marketing initiatives were actively appropriated by young people and reproduced within their Facebook pages to present tastes and preferences, facilitate social interaction, construct identities, and more generally develop cultural capital. These commercial activities within the commercial platforms that constitute social networking systems contribute heavily to a general ‘culture of intoxication’ while simultaneously allowing young people to ‘create’ and ‘produce’ themselves online via the sharing of consumption ‘choices’, online interactions and activities

    A Portable Electronic Nose For Hydrazine and Monomethyl Hydrazine Detection

    The Space Program and military use large quantities Hydrazine (Hz) and monomethyl hydrazine (MMI-I) as rocket propellant. These substances are very toxic and are suspected human carcinogens. The American Conference of Governmental Industrial Hygienist set the threshold limit value to be 10 parts per billion (ppb). Current off-the-shelf portable instruments require 10 to 20 minutes of exposure to detect 10 ppb concentration. This shortcofriing is not acceptable for many operations. A new prototype instrument using a gas sensor array and pattern recognition software technology (i.e., an electronic nose) has demonstrated the ability to identify either Hz or MM}{ and quantify their concentrations at 10 parts per billion in 90 seconds. This paper describes the design of the portable electronic nose (e-nose) instrument, test equipment setup, test protocol, pattern recognition algorithm, concentration estimation method, and laboratory test results

    The main objective of this design was to fulfill a need for a new airplane to replace the aging 100 to 150 passenger, 1500 nautical mile range aircraft such as the Douglas DC9 and Boeing 737-100 airplanes. After researching the future aircraft market, conducting extensive trade studies, and analysis on different configurations, the AC-120 Advanced Commercial Transport final design was achieved. The AC-120's main design features include the incorporation of a three lifting surface configuration which is powered by two turboprop engines. The AC-120 is an economically sensitive aircraft which meets the new FM Stage Three noise requirements, and has lower NO(x) emissions than current turbofan powered airplanes. The AC-120 also improves on its contemporaries in passenger comfort, manufacturing, and operating cost
