The psychological wellbeing of women operating mining machinery in a fly-in fly-out capacity
… in a “bluecollar” work role and the impact of fly-in fly-out (FIFO) mining on their wellbeing. An Interpretative Phenomenological Approach (IPA) was used as a framework to explore the experiences of 19 female machine operators through in-depth interviewing at one mineral mine site in …

Extruded Cellular Fly Ash Construction Materials
Bulk densities and crushing strengths of honeycomb samples consolidated by sintering and by autoclaving were studied as a function of their respective compositions and processing conditions. Typical bulk densities, crushing strengths, and SDR obtained were 1.13 g/cm$\sp3,$ 97 MPa (14,100 psi), and …

CO2 sequestration using brine impacted fly fish
It was hypothesized that South African FA and brine could sequester CO2 through mineral carbonation. A statistical approach was undertaken to optimize the % CaCO3 formed from FA/brine/CO2 interaction with input parameters of temperature, pressure, particle size and solid/liquid ratio (S/L) being …

The effect of fly ash on clay
… studies to determine the effect of mixing fly ash with regional swelling of clayey soils indicated these mixtures were superior in certain engineering properties. Mixtures of clay soil, and fly ash at 10, 20, 30, and 40 percent exhibited reduced plasticity and swelling characteristics while …

On-the-Fly Dynamic Dead Variable Analysis
… information to find more dead variables on-the-fly and further reduce the size of the explored state space. We introduce a definition for the maximal state space reduction possible through an on-the-fly dead variable analysis and then show that our algorithm produces a maximal reduction in the …

On-the-fly assembled multistage adaptive testing
… MST designs that assembled items on-the-fly have shown great potential to concurrently tap the strengths and reduce the weaknesses of both CAT and MST designs (Han & Guo, 2014; Zheng & Chang, 2014; Wang, Lin, Douglas, & Chang,2014). As innovative MST designs are still at their infancy …

Evaluating shrinkage of fly ash - slag geopolymers
… on a user-friendly geopolymer made with Class F fly ash, slag, potassium silicate, and potassium hydroxide. Slag used was constant at 5% of the total mass of the mix. The SiO2 to Al2O3 ratio was kept constant at 3.6, the K2O to SiO2 ratio varied between 0.9 - 2.4 for molarity variations between 4 …

L1 adaptive control within Learn-to-Fly
… to test the feasibility of the NASA Learn-to-Fly concept. The objective of Learn-to-Fly is to reduce or eliminate the need for ground-based aerodynamic modeling in favor of in-flight modeling and control law determination. Due to the initial (high) uncertainty levels, an L1 adaptive control …

Butterflies fly away: insect decline in California, USA
… investigates factors associated with butterfly decline in the western United States. Specifically, I use a combination of observational and experimental approaches to assess the importance of climate change and pesticide use in causing the decline of butterflies over the past 50 years. …

Genetic Intervention in Sensory Systems of a Fly
Die vorliegende Arbeit vergleicht Transgene, die in Drosophila Neuronen exprimiert wurden, um diese abzutöten oder zu blockieren. Tetanus Neurotoxin erwies sich als sehr effizient, um chemische Synapsen zu blockieren. Synapsen, die aus einer chemischen und einer elektrischen Komponente bestehen, …

Interplanetary Trajectory Optimization with Automated Fly-By Sequences
… optimization programs that have an unconstrained fly-by sequence, the design variable limits have the largest impact on the results. When the number of potential fly-by sequences is too large it prevents the solver from converging on an optimal solution. This work demonstrates HGGA is effective in …

Setting and nanostructure of slag-fly ash binders
Slag fly ash binders (SFB) are room temperature hardening binders that have high strength, reasonable setting time, and lower carbon footprint when compared to ordinary Portland cement (OPC). The precursors for SFB are industrial byproducts, namely slag and fly ash. The inexpensive nature of the …
