Many engineering and technology departments at the collegiate level have developed extensive online and hybrid (face-to-face and online) course offerings (Bourne, Harris, & Mayadas, 2005). These courses may meet several goals such as increasing access, reducing university costs, providing schedule flexibility, and increasing curriculum offerings. An additional opportunity for computer-based learning is to increase student success by offering asynchronous learning modules to extend content beyond traditional lectures.


Coupling Dynamic Vehicle-Track Interaction Over Coupled Short And Long Wavelength Rail Defects, Chatpong Chiengson, Sakdirat Kaewunruen, Akira Aikawa 2017 University of Birmingham

Coupling Dynamic Vehicle-Track Interaction Over Coupled Short And Long Wavelength Rail Defects, Chatpong Chiengson, Sakdirat Kaewunruen, Akira Aikawa

There are over 100 million of train journeys around the world every day. The dynamic interactions between vehicle and track impose vibrations and acoustic radiations and become moving vibro-acoustic sources along the railway corridor. Especially when there is imperfection of either wheel or rail, the dynamic amplification of loading conditions and reflected vibration effects on infrastructure and rolling stocks is significantly higher. In practice, imperfection of rail tracks can be classified into short wave length and long wave length defects. The short wavelength defects include high-frequency related rail surface defects such as dipped joint rails, rail squats, rolling contact fatigues ...

Safety is the first priority in operating transportation and transit systems. The public and customers rely on operators to assure them the reliable and safe day-to-day uses of public transports. However, based on recent factual evidences, extreme physical and cyber threats are no longer uncommon and these unpreventable measures are even more dangerous to the public’s daily lives. Such clear examples are the terrorist attacks in Saint Petersburg in 2017, in London in 2017, in Stockholm in 2017, in Brussels in 2016, in Nice in 2016, and so many more. These examples have one thing in common. The transportation ...

An Analysis Of The Environmental Impact Of Electric Vehicles, Ashley Schmid 2017 Missouri University of Science and Technology

An Analysis Of The Environmental Impact Of Electric Vehicles, Ashley Schmid

S&T’s Peer to Peer

Electric cars have the reputation as a possible solution to many modern environmental and economic issues. Electric motors have been an interest of many inventors since the 1830s, but fully electric vehicles were not prevalent until 2008 when Tesla Motors released the Roadster. The looming energy crisis is one of the main motivations for the advancement in renewable and alternative fuel technologies, but since the early 60s, it has been the environmental lobby that has been pushing for this change. The environment suffers from industrialized nations as the amount of greenhouse gas emissions reach new heights every year. Filtration systems ...

Biomass recalcitrance, the resistance of cellulosic biomass to degradation, is due in part to the stability of the hydrogen bond network and stacking forces between the polysaccharide chains in cellulose microfibers. The fragment molecular orbital (FMO) method at the correlated Møller–Plesset second order perturbation level of theory was used on a model of the crystalline cellulose Iα core with a total of 144 glucose units. These computations show that the intersheet chain interactions are stronger than the intrasheet chain interactions for the crystalline structure, while they are more similar to each other for a relaxed structure. An FMO chain ...

Aptamers can be highly specific for their targets, which implies precise molecular recognition between aptamer and target. However, as small polymers, their structures are more subject to environmental conditions than the more constrained longer RNAs such as those that constitute the ribosome. To understand the balance between structural and environmental factors in establishing ligand specificity of aptamers, we examined the RNA aptamer (NEO1A) previously reported as specific for neomycin-B. We show that NEO1A can recognize other aminoglycosides with similar affinities as for neomycin-B and its aminoglycoside specificity is strongly influenced by ionic strength and buffer composition. NMR and 2-aminopurine (2AP ...


Team-Based Learning In Engineering Classrooms: Feedback Form And Content Adds Value To The Learning Experience, Monica H. Lamm, Micheal Dorneich, Diane T. Rover 2017 Iowa State University

Team-Based Learning In Engineering Classrooms: Feedback Form And Content Adds Value To The Learning Experience, Monica H. Lamm, Micheal Dorneich, Diane T. Rover

Monica H. Lamm

An instructional strategy called Team-Based Learning (TBL) has been implemented by the authors in courses that emphasize fundamental engineering concepts that are core to the discipline. TBL is an alternative to conventional classroom lecture instruction. In a TBL course, students are placed on permanent learning teams and the teams work together, during class time, to apply course concepts and solve discipline-relevant problems called application exercises. The goal of introducing TBL in these engineering courses is to enhance the quality of student learning by incentivizing student engagement with course content and fostering team skills. This is achieved by using application exercises ...


Computational And Experimental Analyses Converge To Reveal A Coherent Yet Malleable Aptamer Structure That Controls Chemical Reactivity, Tianjiao Wang, Julie A. Hoy, Monica H. Lamm, Marit Nilsen-Hamilton 2017 Iowa State University

Computational And Experimental Analyses Converge To Reveal A Coherent Yet Malleable Aptamer Structure That Controls Chemical Reactivity, Tianjiao Wang, Julie A. Hoy, Monica H. Lamm, Marit Nilsen-Hamilton

Monica H. Lamm

As short nucleic acids, aptamers in solution are believed to be structurally flexible. Consistent with this view, most aptamers examined for this property have been shown to bind their target molecules by mechanisms that can be described as “induced fit”. But, it is not known to what extent this structural flexibility affects the integrity of the target−aptamer interaction. Using the malachite green aptamer (MGA) as a model system, we show that the MGA can protect its bound target, malachite green (MG), from oxidation over several days. Protection is reversed by an oligonucleotide complementary to the MGA binding pocket. Computational ...
