Analysis Of A Gravity Wave Horizontal Blocking Event Using Hodograph Techniques Applied To Sodium Lidar Data, Neal R. Criddle

All Graduate Theses and Dissertations, Fall 2023 to Present

Atmospheric gravity waves are ubiquitous and important events in Earth’s atmosphere with impacts on space weather and associated technological effects. The population of gravity waves is determined by their formation mechanisms, and their interactions with the background atmosphere. These gravity waves transport energy and momentum into the near Earth space environment, and are responsible for movement of chemical species. Predicting the occurrence of space weather effects, then, is in part a process requiring the characterization of gravity waves. Case studies of unique and interesting gravity wave events are an important part of this process. These allow for the investigation of …

Assessing The Attitudes Of General Education Kindergarten Teachers Making Classroom And Teaching Adaptations For Students With Disabilities, Joseph Graul

All Graduate Theses and Dissertations, Fall 2023 to Present

The transition from preschool to kindergarten can be particularly challenging for children with disabilities in inclusive classrooms (general education classrooms where typically developing children and children with disabilities are taught together) as children face new academic, social, and behavioral expectations. Classroom and teaching adaptations can help these students succeed, making the transition to kindergarten and elementary education smooth and effective. This study looks at how general education kindergarten teachers feel about making various classroom adaptations for children with disabilities and compares current teachers’ views to those of a similar 1999 study conducted by Vaughn et al. which this study replicates. …

Of the 50 third-grade students, 34 participated in eight weeks of observations conducted during lunch recess. Accelerometers and GPS units were utilized to collect data during the observations. The majority of settings on this playground were identified as inclusive. Children with disabilities didn’t engage in organized games as often as …

Mathematical And Statistical Methods To Harness Limited Data In Models For Ecological Space Use Under Global Change, Sarah C. Bogen

All Graduate Theses and Dissertations, Fall 2023 to Present

The dynamics of how plants and animals use space in their habitats has important implications for the fields of ecology and conservation. However, understanding and responding to these spatial and temporal dynamics is often limited by data availability, financial resources and biases. As average global temperatures increase, suitable habitats shift poleward and require local populations to move with suitable habitat, adapt to the changing environment, or risk extinction. Capacity to persist without movement may be estimated by considering changes to a combination of habitat characteristics. Capacity to track suitable habitat may be modeled through synthesizing information on species demographic mechanisms …

Supervised Generative Adversarial Networks For Time Series Generation In Embedding Space, Mohammadreza Eskandarinasab

All Graduate Theses and Dissertations, Fall 2023 to Present

Time series data, such as weather forecasts, stock market trends, or heart rate monitors, plays a vital role in many areas of our lives. However, creating realistic synthetic time series data for research and testing purposes has been a significant challenge due to limitations in existing methods, which often struggle with accuracy and consistency. In this study, we developed two new approaches to generate high-quality time series data more effectively. The first method introduces a dual-feedback system that helps the model learn and replicate real data patterns more accurately by providing guidance at different stages of the learning process. The …

Bioactivity And Synergism Of Tagpo (Ardisia Tomentosa) Molluscicidal Extracts, Darwin C. Gomez, Grechelle Socias, Rosemarie Galanza, Florlyn C. Gayas Ma., Fe T. Piedad, Brian John Sarno

The Philippine Agricultural Scientist

Population control of golden apple snails (GAS, Pomacea canaliculata) is beneficial in rice farming; however, the associated control measures can be expensive and time-consuming. Currently, farmers use synthetic molluscicides such as niclosamide to control GAS infestation, but this has some drawbacks. For example, niclosamide has broad toxicity to non-target organisms and negatively affects the growth of rice seedlings. Plant extracts with potent bioactivity and low toxicity to non-target organisms are attractive alternatives to synthetic molluscicides. In this study, the bioactivity of the crude fruit extract of tagpo (Ardisia tomentosa) was assessed against GAS and tilapia (Oreochromis niloticus) fries. The potential …

The Philippine Agricultural Scientist

This study aimed to evaluate the effects of maturation media and duration on the in vitro maturation (IVM) of Cỏ goat oocytes for the in vitro production of Cỏ goat embryos. In Experiment 1, the highest percentage of matured oocytes and blastocyst rates were observed in the IVM medium consisting of tissue culture medium (TCM) 199 + 10% fetal calf serum (FCS) + 50 ng/mL follicle stimulating hormone (FSH) + 100 μM cysteamine + 10 ng/mL epidermal growth factor (EGF) + 100 units/mL penicillin G potassium + 0.1 mg/mL streptomycin sulphate (P < 0.05). In Experiment 2, Cỏ goat oocytes were cultured in the same IVM medium for 20, 22, and 24 h, respectively. The matured oocyte and blastocyst rates of the 20-h group were lower than those of the 22- and 24-h groups (61.56% vs. 76.81% and 73.48%; 13.76% vs. 24.75% and 24.72% respectively; P < 0.05), while there was no difference between the 22- and 24-h groups (P > 0.05). In conclusion, the TCM 199 medium supplemented …
