A Critical Review On Recent Methods Used For Economically Viable And Eco-Friendly Development Of Microalgae As A Potential Feedstock For Synthesis Of Biodiesel, Yogesh C. Sharma, Bhaskar Singh, John Korstad
A Critical Review On Recent Methods Used For Economically Viable And Eco-Friendly Development Of Microalgae As A Potential Feedstock For Synthesis Of Biodiesel, Yogesh C. Sharma, Bhaskar Singh, John Korstad
College of Science and Engineering Faculty Research and Scholarship
Microalgae are being considered as a viable feedstock for large-scale production of biodiesel. However, though it may look simpler to obtain lipids from microalgae, the overall process of choosing an algal strain, cultivation, harvesting, dewatering, and extraction of oil is quite complicated and not economically prudent at this time. A thorough understanding of algae and the overall biodiesel production process discussed in this paper is vital so that focused research might lower the costs involved. Various diverse species of microalgae are currently being used as feedstocks for biofuel. Heterotrophic culture may be preferred over photoautotrophic cultivation. For cultivation, specially fabricated …

Relationship Of Surface Changes To Metal Leaching From Tungsten Composite Shot Exposed To Three Different Soil Types, Deborah Felt, Steven Larson, Chris Griggs, Catherine Nestler, Michelle Wynter
Relationship Of Surface Changes To Metal Leaching From Tungsten Composite Shot Exposed To Three Different Soil Types, Deborah Felt, Steven Larson, Chris Griggs, Catherine Nestler, Michelle Wynter
United States Army: Publications
Physical changes that occur on the surface of fired shots due to firing and impact with soil may increase the dissolution of muniton metals. Increased metal dissolution could potentially increase metal transport and leaching, affecting metal concentrations in surface and groundwater. This research describes the relationship between the surface changes on fired tungsten–nickel–iron (94% W:2% Ni:4% Fe) composite shots and metals leaching from those shots. Tungsten composite shot was fired into, and aged in, three soil types (Silty Sand, Sandy Clay, and Silt) in mesoscale rainfall lysimeters to simulate live-fire conditions and subsequent interactions between the metals of the composite …

United States Army: Publications
We have previously shown that a hydrophobic alkylating compound, 1,5-iodonaphthyl-azide (INA) can efficiently inactivate the virulent strain of Venezuelan equine encephalitis virus (VEEV), V3000 in vitro. In this study, we have evaluated the safety of INA-inactivated V3000 and V3526 and the protective efficacy of INA-inactivated V3000. INA-inactivated V3000 and V3526 did not cause disease in suckling mice. RNA isolated from the INA-inactivated V3000 and V3526 was also not infectious. Immunization of adult mice with INA-inactivated V3000 induced an anti-VEEV antibody response and protected mice from virulent VEEV challenge. The protective efficacy of INA-inactivated V3000 increased with the use of adjuvants. …

A Possible Pathway For High School Science In A Stem World, Cary Sneider
A Possible Pathway For High School Science In A Stem World, Cary Sneider
Publications
Today‘s high school science teachers find themselves in a period of transition. For the past decade there have been calls for replacing a narrow focus on science education—the traditional courses in physics, chemistry, biology, and Earth and space science—with a broader curriculum on STEM (that is, the four allied fields of science, technology, engineering, and mathematics). However, at present there are no guidelines on what that broader curriculum should include or how it should be designed, and the gulf that has separated science and mathematics seems as wide as ever, despite decades of efforts to bridge the two disciplines. Next …

Much of the national attention on science, technology, engineering, and mathematics (STEM) education tends to concentrate on science and mathematics, with its emphasis on standardized test scores. However as the National Academy of Engineering Committee on K-12 Engineering Education stressed, engineering can contribute to the development of an effective and interconnected STEM education system (Katehi, Pearson, & Feder, 2009). In addition, engineering can provide authentic learning contexts for science, technology, and mathematics. Numerous K-12 engineering initiatives have emerged across the U.S. developing curriculum and conducting teacher professional development (Brophy, Klein, Portsmore, & Rogers, 2008). The focus of pre-college engineering education …

Design Problems For Secondary Students, David H. Jonassen
Design Problems For Secondary Students, David H. Jonassen
Publications
Are there different kinds of design problems? According to Brown and Chandrasekaran (1989), Class 1 design problems are open-ended, non-routine creative activities where the goals are ill-structured, and there is no effective design plan specifying the sequence of actions to take in producing a design model. Class 2 problems use existing, well-developed design and decomposition plans (e.g. designing a new automobile). Class 3 designs are routine where design and decomposition plans are known as well as customary actions taken to deal with failures (e.g., writing a computer program). Jonassen (2011) argued that problems vary in terms of structuredness, complexity, and …

Accidental Releases Of Hazardous Materials And Relevance To Terrorist Threats At Industrial Facilities, Laura J. Steinberg, Nicholas Santella
Civil and Environmental Engineering - All Scholarship
Hazardous material releases, some with serious consequences, are a common occurrence in the U.S. Of late, the hazards posed by releases caused by terrorist attacks or natural disasters have been of particular concern. Although terrorism directed at hazardous material handling industries within the U.S. has not yet resulted in a significant incident, there is much recent experience with serious accidental releases resulting from natural disasters. Case studies are developed from a number of recent natural disasters and severe weather events that resulted in large releases of hazardous materials. These case studies are used to illustrate parallels between the risks posed …
Development Of A Cognitive Work Analysis Framework Tutorial Using Systems Modeling Language, Wilfred Henry Wells
Development Of A Cognitive Work Analysis Framework Tutorial Using Systems Modeling Language, Wilfred Henry Wells
Electronic Theses and Dissertations
At the present time, most systems engineers do not have access to cognitive work analysis information or training in terms they can understand. This may lead to a disregard of the cognitive aspect of system design. The impact of this issue is system requirements that do not account for the cognitive strengths and limitations of users. Systems engineers cannot design effective decision support systems without defining cognitive work requirements. In order to improve system requirements, integration of cognitive work requirements into the systems engineering process has to be improved. One option to address this gap is the development of a …
