Nitrogen Uptake By Two Plants In Response To Plant Competition As Regulated By Neighbor Density, Xuan Jia, Chaohe Huangfu, Dafeng Hui
Nitrogen Uptake By Two Plants In Response To Plant Competition As Regulated By Neighbor Density, Xuan Jia, Chaohe Huangfu, Dafeng Hui
Biology Faculty Research
Plant species may acquire different forms of nitrogen (N) to reduce competition for the same resource, but how plants respond to neighbors with different densities in their N uptake is still poorly understood. We investigated the effects of competition regime on the uptake of different N forms by two hygrophytes, Carex thunbergii and Polygonum criopolitanum, by conducting a hydroponic test of excised roots and an in situ experiment in a subtropical wetland ecosystem. The two species were grown either in monocultures or mixtures with various neighbor densities. Root functional traits and N uptake rates of different N forms were measured. …

Biology Faculty Research
Invasive plants and native weeds (i.e., undesirable plant species) often have negative effects on native ecosystems. However, the effects of weed expansion on soil seed banks and seedling emergence in native forests have not been well investigated. In this study, we used a seedling emergence assay to assess the effects of expansion by a native weed, the perennial C4 herb Wollastonia biflora, on the soil seed bank and above-ground vegetation in forests on Yongxing Island, a coral island in the South China Sea. We found that W. biflora expansion was associated with a reduced abundance of native species in the …
Using Contextualized Materials To Teach English Grammar, Jingyi Yang
Using Contextualized Materials To Teach English Grammar, Jingyi Yang
Master's Projects and Capstones
Grammar learning is the foundation of language learning. Despite its importance, many ESL adult learners consider grammar learning a challenging part, and the effectiveness of grammar instruction has been evaluated low. This is because of inappropriate teaching approaches and the lack of contextualized learning materials. Inappropriate teaching approaches include traditional PPP (Presentation, Practice, Production), which hinder the effectiveness of research-based teaching approaches. Decontextualized and meaningless grammar forms are another underlying challenges of grammar learning. This field project uses task-based language teaching (TBLT) as a theoretical framework. The three literature review themes are the importance and challenges of grammar, grammar instruction …
A Comparison Of The Efficacy Of Methane-Oxidizing Alternative Daily Landfill Covers And Policy Recommendations For Landfill Regulatory Agencies, Eric Lara
Master's Projects and Capstones
Methane (CH4) is a potent greenhouse gas (GHG) that has 28-36 times the greenhouse effect of carbon dioxide (CO2) over a 100-year timespan. Recent remote sensing research conducted by NASA Jet Propulsion Laboratory and Scientific Aviation has indicated that the working face of landfills are sectors of much higher methane emissions than previously considered. A working face location, which is the area of the landfill where daily waste is deposited, lacks the engineering controls present on the rest of the landfill. Controls such as gas collection and extraction wells and substantial covers to ensure surface integrity for methane leaks are …

Frequency Analysis Of Circular Cable Suspended Roofs., Ahmed Badr
Frequency Analysis Of Circular Cable Suspended Roofs., Ahmed Badr
Mansoura Engineering Journal
The main aim of the present work is to investigate the dynamic analysis of circular cable suspended roofs which are the most common forms of suspended roofs using the frequency domain method. Although frequency domain analysis is used basically for linear systems, it may be used to analyze cable suspended roofs for which, wind is considered as the fundamental dynamic factor affecting in these structures. This is due to the fact that the fluctuating wind speed, except for sites in mountainous areas, may be neglected comparing with the mean wind speed. Many circular cable roofs have been analyzed using a …

Berry phase is a powerful concept that unravels the nontrivial role of topology in phenomena observed in chiral magnetic materials and structures. A celebrated example is the anomalous Hall effect (AHE) driven by the nonvanishing Berry phase in momentum space. As the AHE is dependent on details of the band structure near the Fermi edge, the Berry phase and AHE can be altered in thin films whose chemical potential is tunable by dimensionality and disorder. Here, we demonstrate how Berry phase in ultrathin SrRuO3 films provides a comprehensive explanation for the nontrivial Hall response which is conventionally attributed to the …

Item-Based Collaborative Filtering And Association Rules For A Baseline Recommender In E-Commerce, Jessica Lourenco, Aparna S. Varde
Department of Computer Science Faculty Scholarship and Creative Works
In the ever-growing data-driven world today, data increases in many forms, e.g. e-commerce sites uploading new products, streaming services adding TV shows and movies, and music platforms uploading new songs. It would be highly infeasible for end users to quickly browse all this data. Hence recommender systems can benefit end users (individuals as well as companies) in efficiently finding suitable products. Rather than making end users search through a vast array of items, recommender systems can suggest suitable items to users based on popularity of the items and the respective users' buying behavior. Accordingly, in this paper we explore two …

Expanding The Concept Of Comprehensive Area Ratio Parameter To The South-Central States Towards Simplifying The Structural Evaluation Of Flexible Pavements At The Network Level, Nitish R. Bastola
Civil Engineering Theses
The surface deflection bowl data collected through Non-Destructive Testing (NDT) has been widely utilized by various Department of Transportation (DOTs) in the South-Central States and other places. The primary purpose of using deflection-based NDTs in network-level assessment is to identify a weak pavement section that requires further analysis at the project level. The falling weight deflectometer (FWD) test is one of the common NDT based tests utilized by highway agencies in assessing the performance of the flexible pavement. However, a robust method to evaluate pavement sections utilizing FWD data from all the sensors are seldom developed. There is always a …

Frameworks For Part Generation In Multiple Cad Systems And For Cad Simulation With Multiple Users, Jonathan Edwin Sadler
Theses and Dissertations
Companies often require designers to work with and operate between different computer-aided design (CAD) systems. To interoperate between these systems, a neutral design standard for CAD models is needed that allows for generation, customization, and parameterization. Current standards often fail to incorporate file history and design intent. The research proposes a simplified, neutral design format that can be used to generate models in different CAD systems. The format proposes additional functionality not yet found in existing neutral formats or scripts. The system was tested by generating models in both NX and CATIA, then comparing the models for accuracy, flexibility, and …
