Show moreCadmium is considered as one of the most toxic metals and is also classified as a carcinogen. It has similar properties to zinc, iron and copper, which allows it to cause changes in cellular functions. Metallothionein is a metal binding protein, which helps to reduce the toxicity of cadmium in biological systems. When there is excessive cadmium compared to available Metallothionein, unbound, labile cadmium induces indirectly oncogenicity and directly renal damage. The effect of micromolar and supra-micromolar concentrations of cadmium toxicity in causing cancer has been studied widely. Our hypothesis instead aims at the effects of submicromolar concentrations of cadmium chloride on aggressiveness of existing prostate cancer. Hence in this study prostate cancer cells such as PC-3 and LnCaP are exposed to various concentration of cadmium chloride. One of the characteristics of aggressive prostate cancers is Epithelial Mesenchymal Transition(EMT). Our results show that nanomolar concentrations of cadmium chloride induces EMT in PC-3 cells, but not in LNCaP cells. M.S. in Biology, May 2013 Show less

Show moreAs cities expand the amount of impervious surface area increases, which increases the amount of stormwater runoff generated. Urban stormwater runoff contributes to the degradation and poor biological conditions of rivers and streams throughout the United States (USEPA, 2013). Currently, there are several different tools (i.e. computer software and models) available for stormwater managers to assess the effectiveness of best management practices (BMPs) to meet stormwater quality and quantity goals. In an effort to a create a single model that allows stormwater managers to evaluate the effectiveness of BMPs and associated cost information, the U.S. Environmental Protection Agency developed System for Urban Stormwater Treatment and Analysis INtegration (SUSTAIN) (USEPA, 2009). In this study, SUSTAIN is used to determine what BMPs are necessary to meet the Illinois Institute of Technology (IIT) 2020 Sustainability Plan’s goal of achieving 100 percent capture and retention of all stormwater runoff on the IIT campus by the year 2020. Multiple BMPs were simulated in currently available green space and parking lots to evaluate the level of runoff reduction and associated cost of BMP installation. Although the simulations show that reductions in runoff are possible without affecting the current layout of the campus, 100 percent capture and retention is not possible for the entire IIT campus. While the 2020 goal of 100 percent reduction cannot be met for the entire campus, significant reductions in runoff can still be realized with the use of BMPs in different sections of campus with high associated costs.

Show moreBoltzmann transport equation is a theoretical framework for the description of thermodynamics or charge reactions in a system not in equilibrium, which can be applied to the analysis of the interactions of mobile charges with an electromagnetic wave. When the dimensions of the object are small compared to the wavelength, the induced dipole moment provides a means to characterize the collective response while providing insight to the nature of the charge-field interactions. Semiconductor nanoparticles exhibit surface plasmon resonance in the terahertz frequency range and are of current interest for the development of components and circuits in that part of the electromagnetic spectrum. By changing the plasmon frequencies of doped semiconductors through the change of carrier concentration, new opportunities arise for plasmonic manipulation in terahertz region leading to various promising applications. Despite the Drude model's long-term success and convenience in describing the electrical conductivity of metals in terms of dielectric functions, some aspects of polarization are not accounted for by bulk properties. By incorporating the transport equations of the charge carriers with Maxwell's equations, screening effects of charge carriers can be accounted for, enabling the internal field, space charge and induced dipole moment of a semiconductor nanoparticle to be studied.The computations performed for elementary dimer structures in overlapping cases revealed the internal field screening, while the complex dipole moments show dispersion and absorption effects. The numerical algorithms are implemented using the finite element method to investigate the surface plasmon resonance (SPR) induced on the semiconductor particles. Unique SPR modes evolution is observed as the thickness of the overlap region is varied. The characteristics can be interpreted by the migration of local space charge as the level of overlap is varied. This degree of freedom provided by a semiconductor nanodimer could be employed to control the local field near a simple cluster of nanoparticles, with potential for application in sensing and circuit components in the terahertz frequency range.

Show moreThe Delta Tau Delta fraternity wants to make their current house as energy efficient and green as possible. We will look at all aspects of the DTD house and their operations to create a more energy efficient fraternity. During this IPRO we will consider possible alternatives to many issues including but not limited to: mechanical heating system, building envelope, thermal properties of buildings perimeter, roofing materials, air infiltration, ventilation, and occupancy trends. In general, we will collect information regarding the existing conditions and itemize all improvements that could be made to create a more energy efficient fraternity. In addition, we will look for grant assistance to help pay for future energy efficiency upgrades. This will allow us to address what is possible through comparison of funding and needs.
