Drought Effects On Germination Rate Of Two Sagebrush Species, Artemisia Cana And Artemisia Arbusula, And Comparison Of Seed Counts Using A Photography App And Weighing, Sam S. Kelly, Cessair E. Mckinney

Environmental Science & Management Senior Capstones

Sagebrush steppe ecosystems have been impacted by climate change, grazing, and invasive plants. While some widespread sagebrush species have been well-studied, including big sagebrush (Artemisia tridentata), others like silver sagebrush (Artemisia cana) and low sagebrush (Artemisia arbuscula) are understudied. To learn more about how to restore these important ecosystems, we conducted a germination study of two sagebrush species. We germinated seeds from A. cana in petri plates and in soil to compare the rates of germination in both methods, while A. arbuscula seeds were germinated only in petri plates. We also tested the efficiency …

A Multi-Stage Machine Learning Approach To Predict Dengue Incidence: A Case Study In Mexico, Annalisa Appice, Yulia R. Gel, Iliyan Iliev, Vyacheslav Lyubchich, Donato Malerba

Faculty Publications

© 2013 IEEE. The mosquito-borne dengue fever is a major public health problem in tropical countries, where it is strongly conditioned by climate factors such as temperature. In this paper, we formulate a holistic machine learning strategy to analyze the temporal dynamics of temperature and dengue data and use this knowledge to produce accurate predictions of dengue, based on temperature on an annual scale. The temporal dynamics are extracted from historical data by utilizing a novel multi-stage combination of auto-encoding, window-based data representation and trend-based temporal clustering. The prediction is performed with a trend association-based nearest neighbour predictor. The effectiveness …

Making The Water Cycle Accessible And Relevant For English Language Learners, Summer Teed

Graduate Research Papers

The Impact Of Confidence-Based Marking On Unit Exam Achievement In A High School Physical Science Course, Casey Clark

Graduate Research Papers

High school teachers begin each year with a plethora of content standards to teach, however, instructing students how to learn is hardly ever considered. Metacognition and learning how to learn are not present in high school science content standards. The ability to self-regulate our knowledge is essential to assumptions about learning (Cubukcu, 2009). Students are expected to use metacognitive strategies, even if they do not have them. When students work through problems, it is common to expect them to go back and recheck their work. This is a form of metacognition and self-regulation. Asking students apply metacognition can help them …

Resource Estimation For Alpagut-Dodurga Coal Field And Determination Of Spatial Distribution Of Coal Quality Parameters, Yavuz Gül, Oğuzhan Küçükkarasu

Turkish Journal of Earth Sciences

In this study, coal seams of the Alpagut-Dodurga coal field, located in one of Anatolia's most important Tertiary-aged basins of the Çankırı-Çorum Basin, were modeled in 3 dimensions by using Netpro/Mine software and geostatistical methods for the estimation of resource amount. Additionally, the spatial distributions of coal quality parameters (lower calorific value, ash content, and moisture content) were determined using the same software and mapped thematically. Mining activities with inaccurate methods and planning lead to unacceptable reserve losses. The selection and planning of effective and economic production methods could be possible with three-dimensional modeling, accurate determination of spatial distributions of …

Coseismic Surface Deformation And Fault Model Of The 27 May 2017 Mw 5.2 Saruhanlı-Manisa (Western Turkey) Earthquake From Insar, Ahmet Murat Akoğlu

Turkish Journal of Earth Sciences

The shortened revisit times and accurate orbits of the new generation of radar satellites like Sentinel-1 improved the applicability of the synthetic aperture radar interferometry (InSAR) technique to investigate more moderate size events. Here the technique is used to characterize the 27 May 2017 Mw 5.2 Saruhanlı (Manisa) earthquake that took place in western Turkey in the Gediz Graben. Though seismological focal mechanism solutions of the earthquake clearly indicated that the event is due to normal faulting, the nodal plane ambiguity and the presence of two closely located faults in the epicentral region prevented the assessment of the causative fault. …

Determination Of Deformations By Using The Psi Technique At A Common Dump Site Ofthree Different Open-Pit Marble Mines In Turkey, Fati̇h Poyraz, Yavuz Gül, Burakhan Duymaz

Turkish Journal of Earth Sciences

Slopes are formed to carry out mining activities such as stripping, ore production, transportation, and waste management in open-pit mines. The instability of slopes is a potential source of risks for mine safety. An unexpected slope failure may damage people, buildings, and equipment in the immediate area. Moreover, it leads to the disruption of mining production and an increase in production cost. For this reason, the regular examination and systematic monitoring of slopes should be performed to determine the early warning signs of failure. Thus, it may be possible to reach acceptable risk levels and to plan and implement the …

Controls On Deep-Water Slope Channel Complex Fill, Propagation, Stacking, Andorientation In The Middle Eocene-Oligocene Kırkgeçit Formation, Elazığ, Eastern Turkey, Hasan Çeli̇k, Bryan Cronin

Turkish Journal of Earth Sciences

Deep-water channels are well-exposed along the northern margin of the east-west oriented Late Paleocene to Oligocene Elazığ Basin of eastern Turkey. The deep-water slope channel complexes are characterised by their association with prominent normal faults, where they seem to have controlled their geometries at the northern margin. The channels were fed by coarse-grained sediment shed by subaqueous gravity flows such as high and low-density turbidity currents, and both cohesive and noncohesive debris flows, from elevated hinterland across narrow shelves and through canyons and gullies into the channels. The faulting and subsequent folding along the northern basin margin created a significantly …
