Lyme Disease: An Influential Outdoor Hazard, Kevin Kang

Dartmouth Undergraduate Journal of Science

Lyme disease is an important, common illness in New England. A relatively new illness, it was discovered about forty years ago in the town of Lyme, Connecticut. Now, it has become the most common vector-transmitted illness in the United States, with over 30,000 cases annually. Lyme disease arises when a bacterium is transmitted to a human via deer tick bite, so those of us involved in outdoor sports are most likely to contract the disease. Inhabitants of New England and the northeastern U.S. are most vulnerable to the disease, as 95% of Lyme Disease cases occur in only 14 out …

Towards Simulating The Human Brain, Logan T. Collins

Flight Dynamics: Flying Qualities Of Handling Factors Are Engineered Into The Aircraft Design, Nihad E. Daidzic

Aviation Department Publications

Flight dynamics is an aerospace engineering discupline that addresses aircraft stability and controllability. It is also mathematically very intensive and is traditionally the most difficult in the pilot training curriculum. Ultimately, it does not matter how good steady-state performance of an aircraft design is if its flying (handling) qualities are deficient. Paradoxically, the first airplane Wright Flyer, was statically and dynamically unstable, had large control authority, and was difficult to fly. We've come a long way since those early days, but stability is still vitally important in aircraft design and flight ops. The focus of this article will be airplane …

Investigation Of The Durability Of Sisal Fiber/Pla Biocomposite Through Evaluation Of Biodegradability By Means Of Microbial Growth, T Kittikorn, S Kongsuwan, R Malakul

Journal of Metals, Materials and Minerals

The aim of this work was to investigate the microbial biodegradation of 3-(trimethoxysilyl) propyl methacrylate (TPM) modified (silanized) sisal fibres/PLA biocomposites by Aspergillus niger. The modification of the sisal fibres performed excellently, improving hydrophobicity as well as mechanical properties. Compared to the unmodified sisal/PLA biocomposite, it produced superior interfacial adhesion between the fibres and the PLA matrix. In addition, silanization also increased the crystal size and crystallinity in the biocomposite, which decreased thermal decomposition to an observed maximal activation energy of 213 kJ/mol. This indicated the stability of silanized sisal biocomposite in resisting degradation. After the microbial growth test, despite …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The extent of damage in Washington, DC, from the 2011 M_W 5.8 Mineral, VA, earthquake was surprising for an epicenter 130 km away; U.S. Geological Survey “Did-You-Feel-It” reports suggest that Atlantic Coastal Plain and other unconsolidated sediments amplified ground motions in the city. We measure this amplification relative to bedrock sites using earthquake signals recorded on a temporary seismometer array. The spectral ratios show strong amplification in the 0.7 to 4 Hz frequency range for sites on sediments. This range overlaps with resonant frequencies of buildings in the city as inferred from their heights, suggesting amplification at frequencies to …

Publications

Coordination of uranyl (U(VI)) with carboxylate groups on functionalized graphene oxide (GO) surfaces has been shown to alter the reduction potential of the sorbed uranium ion. A quantitative measure of the reduction potential and qualitative estimation of sorption/desorption processes were conducted using cyclic voltammetry, and the proposed coordination environment was determined using the surface sensitive attenuated total reflection mode of infrared spectroscopy (ATR-FTIR). GO is a nanostructured material possessing a large amount of oxygen-containing functional groups both on basal planes and at the edges, which can form strong surface complexes with radionuclides. The presence of these functional groups on the …

Into The Deep: The Role Of Paradigms In Understanding Engineering Education For Sustainable Development, Iacovos Nicolaou, Eddie Conlon, Brian Bowe

Articles

This article presents summary findings of a mixed methods research project exploring the provision of education for sustainable development (SD) in seven Irish engineering degree programmes. Drawing on Sterling’s (2004) iceberg metaphor and Critical Realism it seeks to identify the underlying socio-cultural barriers preventing a holistic integration of SD in engineering education. It argues that the current focus is predominantly on the environmental dimension of SD and that there are a set of reinforcing mechanisms facilitating the provision of disciplinary education aimed at producing technically proficient, employable graduates in which the social dimension of SD is marginalised. This is underwritten …

Reliability-Based Designs Procedure Of Earth Retaining Walls In Geotechnical Engineering, Juan Camilo Viviescas, Juan Pablo Osorio, Julio E. Canon

Articles

The design and construction of foundations, retaining structures and slopes are usually based on deterministic formulations that do not allow the distinction between the natural variability and the inherent dispersion in the geotechnical parameters. Due to the inherent variability of the soil properties, there is a growing trend to implement reliability-based designs in geotechnical engineering to reduce design uncertainties by probabilistic methods. The reliability designs require the definition of the probability density functions of the geotechnical properties, as well as knowledge of the spatial variability of soils. This paper identifies the procedures, type of soil investigations, simulations and the most …
