Show moreThis thesis reports on our preliminary development of methods used to assess the risks that polymer/clay nanocomposite (PCN) food packaging pose to consumers. PCN with 1% - 7% (w/w) montmorillonite (MMT) clay and 3 mass equivalents of maleic anhydride-grafted polyethylene (MAPE) as a compatibilizer dispersed in low-density polyethylene (LDPE) was successfully extruded into thin, free-standing films using a pilot-scaled microcompounder with 65 mm film device. These films had good optical clarity and a reasonably consistent thickness of 35 ± 3 μm. An oxygen permeability analyzer was used to measure oxygen transmission rate and permeability of these fabricated films to demonstrate that they perform similarly to PCN barrier materials intended for commercial applications; these results showed that the films with the highest amount of added clay had better barrier properties than the neat LDPE films. In preparation of experiments to assess whether clay particles can be released from these materials during intended conditions of use, we also explored effective digestion and trace-metal analysis (Inductively Coupled Plasma-Optical Emission Spectroscopy) methods of both pure clay and MMT/MAPE/LDPE films. This work resulted in an effective digestion protocol to fully digest neat clays and PCN films, as well as an analysis method that provides for a 5-orders-of-magnitude linear detection range and single-digit parts-per-billion detection limits for aluminum and magnesium. Silicon was a more challenging element and efforts to eliminate environmental contamination of samples with this element were unsuccessful. While the work presented in this thesis is largely preliminary and numerous questions remain unanswered, the PCN fabrication and ix characterization methods developed here will be invaluable in our future efforts to understand the risks that nanocomposite food packaging materials pose to human health.

Show moreWith increasing penetration of renewable energy, uncertainty challenges ISOs to keep power balance in real-time. As ramping issues draw public attention, many ISOs have instituted flexible ramping products to ensure ramping reserve at generation side. However, not all the ramping reserves are deliverable when a transmission line is already congested. In the real-time market, if an uncertain load estimation is known at peak time t+10mins previously, SCUC/SCED is able to spare transmission reserve by changing the dispatch at time t with additional uncertain load constraints at t. To spare transmission reserve under uncertainty, this research proposes an uncertain load estimation to generate an estimated uncertain load and uncertainty constraints at t+10 in SCUC/SCED: with the help of a stochastic optimization model, uncertainties are quantified as a random actual load y and utilized in a modified stochastic model for undeliverable ramping reserve issues; once the optimal total system generation x is obtained, treated as an estimated uncertain load, uncertainty constraints are added at t+10mins in SCUC/SCED to obtain a secure dispatch at t. Therefore, transmission ramping reserve is ensured by a change in dispatch at t. Numerical results show that this design enhances the economy and scalability of power systems. In addition, scalability analysis proves it works for any scale of power systems with multiple local peak loads.

Show moreInformal observations of a practical and creative approach piloting Blended Library Instruction for undergraduate Civil Architecture and Engineering students, in collaboration with faculty. At Illinois Institute of Technology students don’t receive library instruction as a required class or in tandem with a composition class. Faculty will schedule one-time sessions, which ideally should be planned with a class assignment in mind, but students are rarely engaged with a one time instruction. Many have IKIA syndrome or I Know It Already syndrome. The Millennials are a group that has integrated technology into every aspect of their lives and they assume that retrieving useful or necessary information will be easy. When they discover this isn’t the case lack of time, heightened anxiety, and increased frustration can prevent them from doing their best work. By intentionally creating a similar crisis prior to library instruction, students were more interested in what they stood to gain during pending library instruction. In this presentation we will discuss: 1) A creative means of delivering library instruction to a traditionally challenging population: engineering undergraduate students 2) Qualitative information collected via multiple assignments and interpreted in a quantitative fashion, as well as our observations. 3) A method for preparing students for library instruction that can be applied in almost any discipline without asking the instructor to sacrifice class time.

Show moreOutbreaks of salmonellosis associated with nut butter have raised public concerns of sanitation issues in nut butter processing. The high fat, low-moisture characteristics of nut butters significantly affect the efficiency of regular cleaning and sanitizing programs, allowing cross-contamination issues to persist on processing equipment. Besides organic matter in food soil, microbial load could also be a factor affecting efficacy of chemical sanitizers. The FDA Food Code (2005) require a 5-log bacterial reduction in testing the efficacy of a chemical sanitation method. As a result, evaluation of microbial transfer is essential for establishing methods for equipment sanitation. The first study of this thesis (Section 4.1) evaluated the survival of Salmonella serovars in almond butter at 25 ± 2 oC. This was achieved by investigating the survival of Salmonella Tennessee and Salmonella Oranienburg in inoculated almond butter sample for up to two weeks. These Salmonella serovars were inoculated into creamy almond butter separately and stored at 25 ± 2 oC. Results showed that Salmonella populations decreased slowly and could survive in almond butter for at least two weeks. This study also investigated the effect of initial inoculum level, contact time, food-contact material and bacterial serovar on the subsequent potential for transfer of bacteria to equipment surfaces (Section 4.2). Almond butter inoculated with Salmonella Oranienburg and Tennessee at different inoculums levels (~3, 6, 9 log CFU/g) were spread on 16 cm2 coupons made of polyethylene, polyurethane, Delrin and stainless steel. Microbial analysis was conducted after physically removing all visible nut butter with laboratory wipes. Results for S. Oranienburg and Tennessee followed similar trends of microbial transfer with regards to inoculum level and food-contact surface. The amount x of Salmonella transferred to a food-contact surface was dependent on initial inoculation levels. An average of 0.88 ± 0.22, 1.53 ± 0.15, and 4.59 ± 0.06 log CFU S. Tennessee per 16 cm2 were transferred to the four different food-contact surface types for low, medium, and high inoculum level, respectively. An average of 1.25 ± 0.24, 2.08 ± 0.08, and 4.55 ± 0.35 log CFU S. Oranienburg per 16 cm2 were transferred to the same four different foodcontact surfaces for low, medium, and high inoculum levels, respectively. The third part of this study (Section 4.3) determined the transfer of Salmonella from contaminated food-contact coupon surfaces to almond butter. Uninoculated almond butter was applied on the surface of previously contaminated food-contact coupon surfaces. More than 5 log CFU/16 cm2 Salmonella could transfer to clean almond butter after immediate contact (within 5 min) with the contaminated area. These findings help advance our understanding of factors affecting microbial transfer between nut butters and processing equipment surfaces. This research can be used to support future cleaning and sanitation studies for nut butter processing equipment.

Show moreThis paper explores how TV fans use social media. By revtewmg academic perspectives on fandom ofTV shows and social media in past several decades, this paper discusses the way that audiences react to TV shows using the affordance of social media. At the begirming, this article traces the image, activities, and meaning of fandom. Fans were portrayed as deviant creatures until the late 80s. This image was clarified when people looked into fans and their creative works. Scholars realized that fans productively generated creative products based on the given materials, which reflected the social experience of the creators. Therefore, fandom was soon understood as a way of fans to resist the dominant culture in the society. Later on, social media offer fans an immediate, widespread platform to contribute to the TV conversation. With this platform, normal fans show up. Different from productive fandom, median fans are less active in making new meanings of the TV program. Interestingly, a large number of TV audiences are using social media during the broadcast, participating in the discussion of shows. This evidences the convergence of the traditional media, TV, and the new media, social media. It is also found that comments of TV viewers on social media in turn, influence the content of the TV show. Rather than merely spectators, fans are a part of the TV production. As a special case, gender is discussed from the perspective of fandom. Female composers dominant the fan-writing world. Study the producers and products of fan fiction may provide valuable insights into gender dilemmas in the real world. At the end of this essay, 1 summarize how social media atTect the participation of TV fans and discuss remaining questions worthy of future research. Since fandom becomes ubiquitous in the social media age, it is possible to explore fandom as a way to better understand our daily life.

Show moreThe turbulent boundary layer is one of the most fundamental and important applications of fluid mechanics. Despite great practical interest and its direct impact on frictional drag among its many important consequences, no theory absent of significant inference or assumption exists. Numerical simulations and empirical guidance are used to produce models and adequate predictions, but even minor improvements in modeling parameters or physical understanding could translate into significant improvements in the efficiency of aerodynamic and hydrodynamic vehicles. Classically, turbulent boundary layers and fully-developed turbulent channels and pipes are considered members of the same “family,” with similar “inner” versus “outer” descriptions. However, recent advances in experiments, simulations, and data processing have questioned this, and, as a result, their fundamental physics. To address a full range of pressure gradient boundary layers, a new approach to the governing equations and physical description of wall-bounded flows is formulated, using a two variable similarity approach and many of the tools of the classical method with slight but significant variations. A new set of similarity requirements for the characteristic scales of the problem is found, and when these requirements are applied to the classical “inner” and “outer” scales, a “similarity map” is developed providing a clear prediction of what flow conditions should result in self-similar forms. An empirical model with a small number of parameters and a form reminiscent of Coles’ “wall plus wake” is developed for the streamwise Reynolds stress, and shown to fit experimental and numerical data from a number of turbulent boundary layers as well as other wall-bounded flows. It appears from this model and its scaling using the free-stream velocity that the true asymptotic form of u′2 may not become self-evident until Re ≈ 275, 000 or δ+ ≈ 105, if not higher. A perturbation expansion made possible by the novel inclusion of the scaled streamwise coordinate is used to make an excellent prediction of the shear Reynolds stress in zero pressure gradient boundary layers and channel flows, requiring only a streamwise mean velocity profile and the new similarity map. Extension to other flows is promising, though more information about the normal Reynolds stresses is needed. This expansion is further used to infer a three layer structure in the turbulent boundary layer, and modified two layer structure in fully-developed flows, by using the classical inner and logarithmic profiles to determine which portions of the boundary layer are dominated by viscosity, inertia, or turbulence. A new inner function for U+ is developed, based on the three layer description, providing a much more simplified representative form of the streamwise mean velocity nearest the wall.

Show moreWe simulate the 3D O(1) (Ising) and O(4) spin models by the Monte Carlo method. Interesting high-order cumulants from the 3D Ising and O(4) universality classes are presented and discussed. They all show the non-monotonic or sign change behavior. The critical behavior is instructive to that of the high-order cumulants of the net baryon number in the QCD phase transitions. Maybe it’s difficult to distinguish the universality classes by the high-order cumulants in the heavy ion collisions.
