Show moreThe increasing use of recycled polypropylene in food packaging raises concerns about chemical migration. FDA’s surrogate testing protocol using hexane or heptane as a diluent has evaluated the efficiency of industrial recycling processes in removing contaminants from reclaimed polyethylene terephthalate (PET). Different conditions to optimize surrogate testing of polypropylene (PP) may be needed due to the different sorption behavior of PP relative to PET. This study examines how the interaction between the surrogate contaminant, diluting solvent, and polymer impacts the sorption of surrogate contaminants into PP. Methyl salicylate (MS) and phenylcyclohexane (PCH) were selected as surrogate contaminants based on the current FDA testing protocol and solubility parameters. Swelling and sorption experiments were performed at 40°C for up to 14 days on different types of PP (monophasic homopolymer polypropylene (h-PP), monophasic random copolymer (r-PP), and/or heterophasic block copolymer (heco-PP)) in n-hexane, 2-propanol, and ethanol as diluting solvents. Sorption of 1% (v/v) MS and PCH from each diluting solvent into h-PP was quantified by GC-MS. Results showed that the PP polymers in n-hexane swelled 10%-155% more than the alcohols. Both MS and PCH sorption in n-hexane required a much shorter time, approximately 12 h, to reach equilibrium in comparison to the alcohols, which required 2–10 days. The equilibrium sorption concentration of 1% MS into h-PP from n-hexane was 55% and 136% higher, respectively, compared to sorption of MS from 2-propanol and ethanol. On the other hand, the equilibrium sorption concentration of 1% PCH into h-PP from 2-propanol and ethanol was 11-12% higher compared to the sorption of MS from n-hexane. Our data indicates that solvent swelling cannot be overlooked when determining realistic initial contamination levels in PP. This research will assist the FDA in updating the Recycled Plastics Guidance for Industry and enhance the FDA’s ability to fulfill its mission of protecting and promoting public health.

Show moreMy project is an urban redevelopment following catastrophe. A catastrophic explosion in 2010 left a portion of Nanjing city destroyed. The project proposes a new urban plan to rebuild the neighborhood and restore the community. A powerful explosion at an abandoned plastics factory in Qixia district of Nanjing city has left several people dead and dozens injured. Buildings and vehicles within 100m of the factory destroyed, 3000 citizen got the key of the street and buildings suffered varying degrees of damage in the area 8 miles in circumference. The blast was caused by a leak from a gas pipeline inside the factory, the blast happened after workers dismantling the plant damaged a propylene pipeline. The leaked gas was then ignited when a car engine was started at the scene. There were a community college and several kindergartens in this area, fortunately, it was summer break at that time, no students hurt reported. It is a unique opportunity to develop a plan in an urban context when the prior years of development have been wiped away. The purpose of the project is giving condos return to 3000 people who lost their houses in the explosion and planing mix-used buildings of the community for next 20 years. At present, many old nerghbourhoods in China are being replaced by new ones. In the most cases, the existing urban patternes are erased and a town is built with out any links to what had previouly existed there. My ptoposal is reusing most of the existing tree line streets, river and bridges. The key of this proposal is sustainability, first idea is using existing river to develop a nice wetland park and the second idea is farming gradens.

Show moreHybrid and Plug-in hybrid electric vehicles (HEVs and PHEVs) have received increasing attention from the automotive industry over the recent years. They are typically more efficient and they produce lower emissions than similar ICE-based vehicles, which significantly reduces their negative impact on the environment. In this study, design considerations of two fundamental parts of plug-in vehicles, traction motor and battery charger circuit, have been investigated toward the drivetrain applications in a solar assisted plug-in electric auto rickshaw. Switched reluctance motors (SRM) have been seen as potential candidates for propulsion systems over the last few years. They are robust, capable of performance in harsh operating conditions and have a wide speed range. Conventional SRM configurations have a higher number of stator poles than rotor poles. This PhD. dissertation presents the advantages of a novel SRM configuration with the number of rotor poles greater than number of stator poles and investigates the challenges in its design. Practical design considerations have been proposed and by using them a 3 phase 5 hp 6/10 SRM is designed, constructed and tested. A PHEV is a series or parallel hybrid electric vehicle equipped with a high energy density battery to extend the mileage and get better fuel efficiency. Since the capacity of the battery is higher than the sum of the energy that can be supplied by the internal combustion engine and regained from the regenerative braking, external charging from the grid is necessary. This research also investigates the requirements of the battery charger circuit and proposes low cost topology composed of a PWM boost rectifier cascaded with a bidirectional DC/DC converter. Operation of the circuit has been x xvii analyzed by deriving its mathematical model. Feedback controller requirements to control the input and output current and DC bus voltage have been studied. Critical issues to be considered in parameter selection of the voltage and current controller are explained in terms of universal input operation. In order to verify the analysis presented, an experimental hardware setup has been built and tested.

Title: IMPROVED METHODS FOR DETECTING PARTIALLY HYDROLYZED GLUTEN IN FOOD

Show moreCeliac disease is an autoimmune disorder in susceptible individuals caused by the consumption of gluten, a class of storage proteins present in wheat, barley and rye. There is no cure for celiac disease, and the only effective treatment is strict adherence to a gluten-free diet. Manufacturers who label their products as “gluten-free” must ensure that these products contain < 20 ppm gluten. Analytical methods currently exist for detecting and quantifying gluten in foods. However, quantifying gluten in fermented or hydrolyzed foods presents an analytical challenge. In order to develop reliable and accurate gluten analytical methods, a better understanding is needed with respect to gluten hydrolysis reactions that occur in fermented and hydrolyzed foods. In addition, research is needed to determine ways to control gluten in food production facilities that produce gluten-containing and gluten-free products on the same processing line. The objectives of this project were to: 1) evaluate the effectiveness of different cleaning procedures on removing gluten from a pilot-scale beer brewing line, 2) assess gluten cross-contact from a shared beer brewing line, 3) track the changes in gluten detection in traditionally brewed soy sauce at different stages of production using five commercial gluten ELISA kits and 4) evaluate the effects of an enzyme (a prolyl endopeptidase- Brewers Clarex®) on detecting gluten in beer brewed with barley malt as an ingredient. A pilot-plant scale beer brewing line located at the University of Wisconsin-Madison (UW-Madison) was used to produce sorghum beer (gluten-free beer), barley malt-containing beer and Clarex®-treated barley malt beer. Three cleaning methods (a push-through cleaning treatment, a hot water rinse, and a full cleaning procedure involving the use of an alkaline detergent) were evaluated for effectiveness at removing gluten residue from the pilot-scale brewing line at UW-Madison. Cleaning study results indicated that a hot water rinse and a push-through cleaning treatment with sorghum beer were less effective in removing gluten from equipment in the brewing line than a full cleaning procedure that included use of an alkaline detergent solution followed by a final hot water rinse. Gluten-free sorghum beer samples used to evaluate cross-contact from an inadequately cleaned brewing line were analyzed, and up to 105.1± 9.3 ppm (μg/mL) gluten was detected using the RIDA Competitive ELISA test kit which is designed to detect hydrolyzed gluten. Model soy sauce products were produced in a pilot-plant at Kikkoman R&D Center in Japan, and samples were obtained at different stages of production. Studies that traced gluten in soy sauce products found that high levels of gluten could be detected at the early stages of production prior to fermentation. However, gluten concentrations in soy sauces after fermentation were below the limit of quantitation (LOQ) for all of the gluten ELISA kits evaluated in the study. Use of Clarex® during the production of barley malt beer resulted in substantial reductions in the amount of gluten (intact and partially hydrolyzed) detected in beer compared to the control treatment without added enzyme. Although, gluten was detected at levels >20 ppm in some Clarex®-treated beer samples, filtration treatment further reduced gluten concentrations in these beer samples below 20 ppm gluten. Results of this project indicate that use of adequate cleaning procedures is needed to control gluten in food production facilities that have shared processing lines. Some fermentation and hydrolysis reactions that occur in food result in substantial reductions in gluten content as measured by ELISA. However, more work is needed to determine if celiac-reactive peptides still remain in these products.

Show moreBio-polymeric materials derived from renewable biomass have successfully replaced conventional materials in many applications. Despite covering 10-15% of the current global plastic market, the application of the Bio-polymeric materials in the field of building facades has hitherto been limited. Unlike the conventional façade materials, Bio-polymeric materials can lessen the carbon footprint of the building façade significantly, reduce a considerable percentage of heat loss, and contribute in alleviating the amount of C&D waste dumped in landfills each year. This will help in saving the natural resources, conserving landfill spaces, decreasing pollution rates, and reducing the overall building weight and energy consumption. Accordingly, this research aims at developing a revolutionary lightweight building façade panel, made from Bio-polymeric agri-based materials, to replace the curtain wall glass and aluminum panel in office buildings, and to assess its impact on the environment, the building energy consumption, thermal performance and structural stability. To achieve that, the research discusses in the first place the potentiality of employing these materials while exploring the main physical and environmental challenges they may confront when introduced to the building facades realm. Secondly, the research adopts rigorous selection criteria to facilitate proposing innovative opaque/transparent materials capable of handling all the environmental, thermal, optical, functional, and economic considerations of the building facade. Thus, 1236 state-of-the-art Bio-polymeric materials have been exposed to a strict methodical screening process through structured quantifiable constraints. MCDM methods have then been employed to enable sorting and ranking the resulted set of candidates considering their order-of-preference in achieving the aforementioned performance criteria. Finally, computational simulation tests have been carried out to ensure that the BioEnclos© Façade Panel satisfies all the energy and building code requirements in terms of heat transfer, energy performance, optical properties, and structural behavior. Consequently, the simulation findings have demonstrated the great capabilities the BioEnclos© Façade Panel can provide to the future of the building façades. Through its several options, the BioEnclos© Façade Panel can reduce the weight of the entire building façade by a range of 43-53%. It also can improve the façade’s thermal resistance and energy savings by a range of 31-52%. In addition, it can maximize the visible light transmittance through the façade’s assembly by a range of 15-31%. Moreover, the BioEnclos© Façade Panel can be commissioned in different colors/textures with good UV radiation resistance, self-extinguishing abilities, exceptional 50-70% reduction in CO2 emissions, and multiple end-of-life options.
