Optimization Of Nitrate Removal From Aqueous Solution By Acid-Activated Rice Straw Supported Nano Zero-Valent Iron Using Response Surface Methodology, Dalia A. Ali Eng, Nagwa Mahmoud Al-Mansi Prof, Mohamed Amin Sadek Prof., Ahmad Wafiq Abolnasr Dr.

Chemical Engineering

Rice straw is one of the most common agricultural wastes due to its large production amounts. Energy valorization of rice straw is a technology used for nitrate removal as the produced ashes used to generate the adsorbent by means of an alkali dissolution followed by acid precipitation. The novelty of the proposed process is that the production of the nano zero-valent iron supported acid-activated rice straw (AARS-nZVI) adsorbent is carried out without the energy valorization process but, through an acid activation for rice straw followed by precipitation of nZVI particles on its surface. The new adsorbent synthesis, characterization and application …

Feasibility And Implications Of The Modular Construction Approach For Rapid Post-Disaster Recovery, Jin Choi, Pedram Ghannad, Yong-Cheol Lee

Civil and Environmental Engineering and Construction Faculty Research

The adverse social and financial impacts of catastrophic disasters are increasing as population centers grow. In recent years, destroying homes and infrastructures has resulted in a major loss of life and created countless refugees. For example, Hurricane Katrina in August 2005 damaged over 214,700 homes in New Orleans and forced over 800,000 citizens to live outside of their homes due to flooding. After disastrous events, the government agencies have to respond to post-disaster housing issues quickly and efficiently and provide sufficient resources for temporary housing for short-term disaster relief and reconstruction of destroyed and damaged housing for full rehabilitation. Modular …

Solar Pv Feasibility Study On Higher Education Institutions In Connecticut, Sai Pujitha Karanam

Master's Theses

One of the most common issue in Connecticut (CT) is the high electricity rates. CT stands among the top five states for its high electric rates due to limitation in transmission facilities and storage of natural gas. Education institutions serve as good places to install photovoltaic systems as they have a large number of buildings available. Photovoltaic systems are a growing alternative energy source that reduces the electricity demand and hence higher education institutions should start implementing these technologies to reduce the burden of paying more for electricity bills.

The primary objective of the study was to analyze the economic …

Particle Studies In The Lab And Pilot-Scale Coal Combustion Systems, Dishant Khatri

McKelvey School of Engineering Graduate Student Theses & Dissertations

In the past century, coal contributed more to the global electricity supply than any other source. Currently, it alone accounts for over 35% of the global electricity supply. Though coal is globally well-distributed and can provide cheap, stable, and reliable energy on demand, it emits a large amount of carbon dioxide—a greenhouse gas responsible for global warming. Additionally, it is a major source of particulate matter (PM) pollution. Thus, in recent years, to reduce the impact of coal on climate, several policies have been introduced to phase out coal. However, replacing coal with intermittent renewables has led to a reduction …

Advanced Materials For Air Pollutants Removal In A Combustion System, Sungyoon Jung

McKelvey School of Engineering Graduate Student Theses & Dissertations

Air pollutants directly or indirectly impact human health and the environment. Large quantities of CO2, volatile organic compounds (VOCs), and particulate matter are emitted from combustion systems, and cause climate change, smog formation, and pose serious health risks. The increasing demand for the remediation of air pollutants at the source has drawn much attention to the use of advanced materials due to their high reactivities and special properties. In order to achieve the successful application of advanced materials for the remediation of problematic emissions, three aspects, (1) synthesis method, (2) characterization of materials’ structural properties, and (3) evaluation of materials’ …

Influence Of Aggregates In Concrete On Fiber-Optic Based Thermal Integrity Profiling Analysis Of Concrete Structures, Ruoyu Zhong, Wen Deng

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Fiber-optic sensor has drawn wide attention in the non-destructive testing and evaluation of civil engineering materials due to its high accuracy and resolution as well as cost-efficiency. Currently, using optical fiber as the temperature sensor is proposed to conduct the thermal integrity profiling (TIP) of concrete structures. However, concrete is not a thermally homogeneous material as assumed in current studies of concrete TIP. Its essential components, such as aggregates may cause thermal inhomogeneity problems when implementing fiber-optic sensors for TIP. In this paper, we use the concrete structures with different grades of aggregates to conduct numerical simulation for non-destructive thermal …

Isolation And Characterization Of Bacteria In A Toluene-Producing Enrichment Culture Derived From Contaminated Groundwater At A Louisiana Superfund Site, Madison Mikes

LSU Master's Theses

In an effort to better understand the role that various microbes may play in toluene production, bacteria from a toluene-producing enrichment culture derived from contaminated groundwater at a Superfund site were cultivated and isolated on low nutrient solid media. A total of 14 solid medium formulations containing varying pH ranges, carbon sources, solidifying agents, and incubation gas headspaces were used to obtain 278 isolates in pure culture. Isolated bacteria, identified using partial 16S rRNA gene sequences, were most closely related with the genera Anoxybacillus, Azospira, Bacillus, Bradyrhizobium, Cellulosimicrobium, Micrococcus, and Propionicimonas.

Resonance Of Droplets In Constricted Capillary Tubes: Critical Factors And Nonlinearity, Chao Zeng, Wen Deng, M. Bayani Cardenas

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Resonance of droplets in constricted capillary tubes responding to external vibratory excitation can be theoretically characterized by the abstract coefficients such as resonant frequency and rate of damping. A physically sound model, however, is needed to relate these abstract coefficients to the fluid properties of two-phase fluid, geometric properties of tube, and features of excited waves. A hydrodynamic model, based on the moving-boundary control volume concept and the transient oscillatory velocity profile, was developed to characterize the resonance of droplets. This model was validated against computational fluid dynamics simulation results expressed in both time and frequency domains. Dominant factors including …

Study The Effect Of Damping Change During The Dynamic Analysis Of A Reinforced Concrete Bridge With Neoprene Cushions, Mais Ghassoun

Emirates Journal for Engineering Research

The damping ratio has a important effect on the dynamic behavior of the bridges. and it is customary when designing to assume it as a predetermined fixed value independent of the response amplitude and frequency of the structure . A lot of experimental research worked on identifying them, but the dependence of damping and other dynamic characteristics of vibration amplitudes and their impact on responses and the results of the analysis need more scrutiny and simulation due to the difficulty of conducting vibration experiments for structures of realistic dimensions and large weights such as a RC bridge, which necessitated a …
